Agricultural sprayer uses what physics knowledge

Agricultural sprayer is in the same liquid, high velocity, low pressure; velocity of small, high pressure. The fluid will automatically flow from the high pressure low pressure. In the low agricultural sprayers  flow through a three-way tube, flow to the high speed of the flow of air. The water is of high speed air to tear into droplets of a droplet (ideas out of the water, the tap water was just beginning to slow, gradually increasing the speed of; but later becomes a drop of a drop). These small water droplets sprayed out after a fog. High speed flow obstacles after splitting into small droplets of principle of second kinds of use is to put water into the tube backpack weed sprayer  by high velocity flow, high velocity flow obstacles after splitting into principle of small water droplets. The situation like a faucet after fingers blocked. Agricultural sprayer use of the structure, the cost is low. Centrifugal force principle of liquid thrown out of third is a high-speed rotating liquid atomizing disk will be thrown by centrifugal force, tear into small droplets similar to an umbrella rotation when the situation of ultrasonic Trigger Sprayer  principle of fourth is the principle of ultrasonic atomizer. Vibration can cause "waves" in the water, the ultrasonic vibration frequency is very high, so it's "wave" of the wavelength is very small, so its "spray" -- the small droplets are very small, these small water droplets into the mist.

An antifouling garden sprayer

An antifouling garden sprayer, which comprises a barrel body, a strap, joystick, nozzles and other parts, garden sprayers backpack  is characterized in that: the top part of the barrel body is arranged into a slope to the edge of the middle low elevation, and near the cylinder mouth is arranged around the drainage groove, compared with the back type garden hand sprayers  has the advantages of existing, liquid pollution preventing leak out from the top of the cylindrical body of the manipulator of the body. An antifouling garden sprayer, which comprises a barrel body, a strap, joystick, nozzles and other parts, which is characterized in that: the garden pressure sprayer  of the cylinder body is provided with a slope of garden sprayer to the edge of the middle low elevation, and near the cylinder mouth is arranged around the drainage groove.

Agricultural sprayer put into use

Agricultural sprayer is suitable for water, dry field crops, pest control, realize mechanized spraying pesticide. Agricultural sprayer spray arm around each one about 5 meters long, agricultural sprayers  on the nozzle in the March 18, only 1 people control, pesticide will come out automatically from each nozzle in spray (pictured), fast speed, wide spraying, like a small airplane wings in the fields. It is understood, at present a lot of field of pesticide spraying equipment is still mainly manual, knapsack sprayer, type, technology is relatively backward, the basic use of large flow, coarse droplet, even rain type, full coverage spray pattern, resulting in liquid waste, land and agricultural products exceed the bottle plastic sprayer  drug residues, and labor costs into the larger. Using agricultural sprayer, the control cost can be greatly reduced and the pesticide pollution. The professional cooperatives just sum accounts: in the past, the traditional control of 300 acres, a day to 60 workers, each worker wages need to Knapsack Sprayer  a day; the machine is put into use, now a day can save 5400 yuan, every day as long as 200 yuan cost of oil per acre dosage, only the original manual spraying 60% the field, reduce the pollution. In the spraying efficiency, now 2 man rotation operation, a day can be homework 300 acres to 400 acres, the liquid medicine not only in crop leaf surface and a back surface attached evenly, and can easily reach the roots of crops, water automatically, automatic spray, increased more than 10 times than the manual spraying efficiency.

Agricultural sprayer remind you several advantages and disadvantages of the sprayer

A, an ordinary hand-operated sprayer: advantages: 1, low price. 2, convenient repair parts prices low. Disadvantages: 1, low efficiency, high labor intensity is not suitable for large area operation. 2, the drug had run, take, drop, leakage phenomenon, operating agricultural sprayers  body easily liquid wet, easy poisoning not environmental protection. 3, repair rate is high too much trouble. Two, automatic pressure sprayer: advantages: 1, high efficiency (3 to 4 times of common manual sprayer), low labor intensity, continuous operation. 2, the vulnerability of small repair rate is the lowest, no use cost. 3, the atomization meet or exceed agricultural sprayer, direct injection process up to 7 to 11 meters. Disadvantages: 1, the backpack pressure sprayer  must spend the first two minutes into the potion to pressure sprayer, can spray. 2, the use of methods and other different sprayers is to read the instructions to use. Three, the electric sprayer: advantages: 1, high efficiency (3 to 4 times of common manual sprayer), low labor intensity, easy to use. 2, the first impression is good, easy sales disadvantages: let n 1, battery decided agricultural sprayer continuous operation time. 2, too many brands of different models accessories not general repair is not easy, repair costs are too high. The warranty period after the battery is almost, a more than 100 pieces, water pump is easy to have trouble isn't too good repair. 3, due to the electrical appliances thing, must by the professional repair. Four, motor-driven backpack weed sprayer  advantages: 1, high work efficiency, good spraying effect. Disadvantages: 1, the purchase price is high, the use of high cost, a barrel of water to a few cents to a dollar money. 2, since the major, noise, pollution, machine temperature is high, operation machine hand environment. 3, need a professional repair.

Common problems agricultural sprayer in use and the elimination method

Agricultural sprayer, spray pressure agricultural sprayers  bad: if the inlet valve is dirt shelved, removable inlet valve, cloth to remove dirt from skin bowl; if damaged, can be replaced with new rubber bowl; if connecting parts not fitted with sealing ring, or because the seal damage and leakage, can add or replace sealing ring. No spraying fog: agricultural sprayer if by tilting hole nozzles were blocked by dirt, can dredge inclined hole; if the nozzle blockage can be disassembled for cleaning nozzle, but can not use iron or steel and other hard objects to poke holes, garden sprayer  the hole expansion, the spraying quality variation; if the tube filter clogged or water valve ball put up, should be cleaning the filter screen and put the dirt cleaning ball. Switch Water Leakage or the screw does not move: if not tighten the switch cap, screw the switch cap; if the wear due to the switch core on the washer, gasket should be replaced; switch does not move, the reason is placed for a long time, or use it for too long, the switch core by chemical etch and bonded to the agricultural sprayer, remove the parts in kerosene or diesel cleaning; are difficult to remove, but after a period of time in kerosene, and then removing can be removed, not available hard knocks. The backpack garden sprayers  Water Leakage: if by loose joints, screw the nut; if damaged because the gasket is not flat or, should the washer flat, or replace the gasket; if the shrinkage of hardening dry washer, can be soaked in animal oil after use.

The work principle of agricultural sprayer

The company carries on the agricultural sprayer in the technology and structure is more improved and adjusted well, to develop wind send remote spray machine intermediate products - Remote backpack garden sprayers  agricultural sprayer, at the beginning of design with high efficiency, high quality products as our design philosophy, in comparison with the similar products, it in high efficiency, energy saving, environmental protection is particularly prominent, the performance of a minute can home garden sprayer  more than 40 square meters area coverage. Fully applicable in the township and rural complex terrain, and in the large area of farmland, more can reflect the machine outstanding performance, with larger area per hour.

Agricultural sprayer advantage:

1 long range, two stage fan, high backpack garden sprayers  pressure, large volume, uniform, fine mist of saving water and medicine. 2.agricultural sprayer penetrating; target is good, the droplet drift less convenient operation. 3 the program control, remote operation. 4 can perform precision spray, high medicament utilization rate, saving medicine, little pollution, low cost. 5 low labour intensity, high work efficiency. 6 and the garden pressure sprayers three hanging, hanging operation; agricultural sprayer device can be adjusted up and down. 7 has the advantages of simple design, convenient repair and maintenance. Parameter description of function: Scope: City Garden, orchard, a greenhouse, health and epidemic prevention, crop pest control.

After the agricultural sprayer control flowers, turf advantage and use method

After the agricultural sprayer spray in prevention and treatment of flowers, grass and crop pests and diseases, compared with the sprayer used, with fast, efficient, convenient, save cost etc.. Specific performance:
A, use less water
After the  agricultural sprayers  is used in the pesticide solution, or only after dilution of very low times, so it does not need a large amount of water.
Two, less dosage
Spraying liquid per 100 grams, rather than tens of kilograms, or even hundreds of kilograms. Therefore, when in use, can greatly reduce the labor intensity, saves labor.
Three, droplet distribution
After the agricultural sprayer is not the solution directly spray on plants, but with the wind so that the diameter is only tens of microns droplet dispersion drift, then around plants "micro flow" effect, the droplet distribution in leaf and the whole plant positive, negative and side. So, than the large amount of water diluted reagent for higher rate of killing pests, especially has developed resistance to pests to some, better. Because of the pesticide liquid killing function than diluted with water several times higher than even a few times.
Four, easy to use
After the agricultural garden sprayers backpack  nose always keep in higher plant height of about 1 meters. Because this kind of spray nozzle saves liquid, liquid outflow to the bottle down. Therefore, when the motor is not open, the bottle should be below the head at the top. During the spraying, should first start the motor, then change the bottle and the position of the head, the bottle at the top, bottle mouth downward, the bottle body is perpendicular to the ground, the medicine liquid can flow automatically.
During the spraying, started by the downwind direction, the route to be separated with a certain distance, the spraying range. The size of back sprayers  should be based on the wind speed and flexibility. Wind hours, spraying range should also be smaller, otherwise should be larger, generally 3 to 3.5 meters is appropriate. Each time in the morning, afternoon or preferably shade, avoid sun exposure. Ultra low volume spraying the best use of systemic insecticides, fumigants or stomach poison. General dosage per 50 grams. For the amount of water available, "equivalent method"

Agricultural sprayer

Agricultural spraying machine is a machine liquid dispersed, is a kind of spraying machinery, agricultural, medical and other uses points (such as industrial), agricultural classification for plant protection machinery agricultural machinery. Commonly known as human driven sprayer, power (engine, motor) driver for sprayer. The spray machine according to the working principle hydraulic, pneumatic and centrifugal sprayer. According to carry way holding, backpack, shoulder type, pedal type, stretcher, transportable, self-propelled, vehicle type, hanging type separation, and aerial spraying machine.

2 principles of editing

A is the Bernoulli principle. The principle of Bernoulli said that at the same flow, velocity, pressure flow rate, pressure big. Low pressure fluid will automatically flow from the high pressure. In the trigger sprayers tube (specific graph cannot be drawn out, their understanding), low flow to the high speed of the flow of air. The water is high speed air to tear into droplets of a droplet (ideas out of the water, the tap water column is beginning to slow,; but later speed increases gradually becomes a drop of a drop). These small water droplets sprayed out after a fog.

The second use is put water into the tube caused by high velocity flow, high flow barriers after splitting into small droplets. Cases like the tap next to large stuffed his fingers. Sprayer household use this structure, low cost.

The third is to make water (water is the charge on the dielectric), the water into droplets repel each other with the same charge. This method is very small droplet. The same principle is also used to give the car paint.

The fourth is the ultrasonic backpack garden sprayers. Vibration can cause "spray" on the surface of the water, the ultrasonic vibration frequency is very high, so the "wave" of the wavelength is very small, so its "spray" -- small droplets are very small, these small water droplets into the fog. The hospital throat spray machine treatment of respiratory diseases is to use ultrasonic .

Easy to cause injury factors on vegetable

First, the types of pesticides factors

Different types of pesticides on different vegetables injury to different degrees. Organochlorine insecticides such as melons and vegetables easy to produce injury, water pressure sprayer fenthion on cruciferous vegetables seedlings produce injury.

Second, the pharmaceutical dosage forms and the use of concentration

Different formulations of pesticide phytotoxicity possibility of different sizes, usually oil> Emulsions> WP> Powder> Milk> granules. Pesticides appear oil, cream and other stratification, precipitation occurs, wettable powder caking, low suspension, powder flocculation, etc. will increase the likelihood of injury produced. Use the higher the concentration, the more prone to injury. Generally soluble in water, small molecular weight pesticides easy to produce injury. Bordeaux mixture on a variety of vegetables such as security, and copper sulfate soluble in water, on a variety of vegetables unsafe.

Three, misuse of pesticides

Because improper storage, causing pesticides mark off, or labels is unclear, or remember name of the drug, or the wrong medicine, or as long as what is grass herbicides can be used, such as herbicides, fungicides or pesticides will the use, or the monocot crop herbicide used dicotyledonous crop fields, and this will have a serious injury, or even never produced.

Fourth, the wrong mix of pesticides

Mix between two or more pesticide misuse, garden water sprayer but also easy to produce injury. Such as Bordeaux mixture and lime sulfur can not mix the two should be used in conjunction with a certain time interval.
