Technology and the content of the invention of garden sprayerd

Technical field The utility model belongs to the field of [0001] tools, in particular to the back sprayers . The technical background Now [0002] garden sprayerd, the piston rod hole and piston rod cylinder at the top of the piston rod wear because without gap seal, make operation liquid cylinder will leak out from the top, because the operator load carrying forward body, liquid leaking out from the top of the cylinder flow to the operator's back, pollution corrosion body. The content of the invention [0003] the design purpose: in view of the existing garden sprayerd was improved, garden sprayers backpack  design capable of preventing leaking out from the top of the cylinder of liquid pollution control body of the sprayer. In order to realize the aim of the design of [0004], the following technical scheme: which comprises a barrel body, shoulder straps, joystick, nozzles and other parts, which is characterized in that: the top of the barrel body is arranged to the edge of the middle slope low rise, and near the opening of the cylinder around each set drainage groove. Characteristics compared with the prior art, the utility model [0005]: with the proposal, because the design of the slope to the edge set into low rise in the middle of the top of the cylinder, and near the cylinder mouth around each set drainage groove, liquid leakage out of the overland flow to the drainage groove back bucket, so compared with the existing backpack garden sprayers , has the advantages of liquid pollution preventing leaking out from the top of the cylinder body of the manipulator.

Garden sprayer making principles and skills

1, the box is made of engineering plastic From ultra light, less susceptible to chemical erosion, anti UV, prevent the aging of polypropylene produced. High strength, garden sprayers  to deformation. Garden sprayer usually if maintenance is good, can be used 7-8 years. Have a handle, mixer, liquid level indicator, screen, and have comfortable. 2, with right hand or left hand operation convenience Garden sprayer can be garden hand sprayer  with the right or left hand operation. 3, standard parts and accessories, cutting to ensure the supply of Parts and accessories of all, it is easy to replace (such as multi nozzle spray rod and a lengthened spraying bar, hose, protective cover, voltage regulator). 4, have a wide range of optional accessories Garden sprayer to meet the different needs of plant protection (such as special herbicide spray, different backpack weed sprayer  output nozzle etc.). 5, save spraying dosage The watertight and fog fine and uniform, according to garden sprayer, the liquid medicine can save about 20%.

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.
