Abstract

The invention relates to a power sprayer free of water carrying and belongs to the technical field of agricultural machinery. The power sprayer is characterized in that a pesticide box and a water pump are respectively fixed on an underframe, the pesticide box is communicated with a flowmeter through a pesticide inlet pipe, a pesticide liquid control valve is arranged at the bottom of the flowmeter, a water sucking filter box is communicated with the flowmeter through a water inlet pipe, the flowmeter is communicated with a water pump inlet through a pesticide mixing water inlet pipe, a water pump outlet is communicated with a spray gun through a pesticide mixing water outlet pipe, and the pesticide mixing water outlet pipe is simultaneously communicated with the pesticide box through a release valve and a pesticide returning pipe. The power sprayer free of water carrying has the advantages that the power sprayer can be operated by one or two persons, is convenient, flexible, large in spraying area and high in efficiency, a heavy process of carrying clean water and mixing pesticides is omitted mainly, and the power sprayer is extremely suitable for paddy field pesticide spraying.

Description

Exempt from the backwater motor atomizer

Technical field

The invention belongs to the agricultural machinery technology field.

Background technology

At present, spraying insecticide in the paddy field generally is to adopt two kinds of mechanical work, and a kind of is large-scale sprayer, and it can be implemented large tracts of land and spray, operating efficiency is high, and spray effect is good, and its deficiency is to be only suitable in the large tracts of land operation, the plant equipment cost is high simultaneously, needs several individuals to operate simultaneously, and operation requirements is high; Another kind is the manual hydraulic spray of one man operation's back of the body back of the body formula, is suitable for the flexible operation of small size, and operating efficiency is not high, labor intensity of operating staff is large, wherein, the exactly needs of labour intensity maximum often add clean water in medicine-chest, become spraying agent to blend agricultural chemicals.

Summary of the invention

The objective of the invention is: a kind of backwater motor atomizer of exempting from is provided, and it can be fetched water on the spot and blend agricultural chemicals and implement the paddy field operation of spraying insecticide.

Technical scheme of the present invention is: medicine-chest and water pump are separately fixed on the underframe, medicine-chest is communicated with flowmeter by drug-feeding tube, be provided with the liquid control valve in the flowmeter bottom, the suction filter cartridge is communicated with flowmeter by water inlet pipe, flowmeter is communicated with unit fixed on water pump suction by mixing the medicine water inlet pipe, exit of pump is communicated with spray gun by mixing the medicine outlet pipe, mixes the medicine outlet pipe and is communicated with medicine-chest by graduated release valve and time pencil simultaneously.

Regulate handle in suction and be provided with hand throttle, regulate line in suction and be provided with the backguy converter.

Water inlet pipe entrance at the suction filter cartridge is provided with inlet non return check valve, and the water inlet pipe entrance outside in the suction filter cartridge is fixed with backing plate.

The invention has the beneficial effects as follows: but one or two people's operation, convenient, flexible, spray area is large, and efficient is high, and main is to have removed from needing mixed this heavy program of medicine of fortune clean water, very applicable for paddy field spray medicine.

Fig. 2 is A-A sectional top view of the present invention;

Fig. 3 is the present invention's filter cartridge package assembly cutaway view that absorbs water.

Embodiment

Below in conjunction with accompanying drawing the present invention is described further:

As shown in Figure 1, 2, the 1st, medicine-chest, the 2nd, underframe, the 3rd, water pump, the 4th, graduated release valve, the 5th returns pencil, the 6th, water inlet pipe, the 7th, suction filter cartridge, the 8th, suction pull bar, the 9th, handle, the 10th is regulated in suction, and line, the 11st is regulated in suction, flowmeter, the 12nd, drug-feeding tube, the 13rd mixes medicine water inlet pipe, the 14th, mixes medicine outlet pipe, the 15th, spray gun, the 16th, liquid control valve, the 17th, backguy converter, the 18th, hand throttle, the 19th, inlet non return check valve, the 20th, backing plate.

Discharge orifice is arranged at the bottom at medicine-chest 1, drug-feeding tube 12 is sent into medicine in the flowmeter 11 from discharge orifice, flowmeter 11 is transparent hollow cylinder, so that observe, in flowmeter 11 bottoms liquid control valve 16 is installed, to regulate that dose enters what, suction filter cartridge 7 actual integral body are box bodys that fixedly form by the sieve plate outside, so that the silt during suction in the filtering water, water inlet pipe 6 entrances at suction filter cartridge 7 are provided with inlet non return check valve 19, inlet non return check valve 19 is by an elasticity glueballs with tail, be affiliated on water inlet pipe 6 entrances by " people " font steel wire, all there is the edge of sticking up the front and back of suction filter cartridge 7, so that drag, the water inlet pipe 6 entrances outside in suction filter cartridge 7 is fixed with backing plate 20, is convenient to water inflow water inlet pipe 6 to form the slit, backguy converter 17 is engines that control drives water pump, can realize by directly controlling on the engine or controlling by hand throttle 18.When water pump 3 just starts or throttle when excessive, mix the parts such as medicine outlet pipe 14 and spray gun 15 and can cause very large hydraulic pressure, easily will mix the parts such as medicine outlet pipe 14 and spray gun 15 and water pump 3 and cause damage, therefore, on mixing medicine outlet pipe 14, be provided with back again pencil 5 and graduated release valve 4, when generation hydraulic pressure is excessive, automatically open-minded by graduated release valve 4, liquid is entered in the medicine-chest 1 by returning pencil 5.

Claims

1. exempt from the backwater motor atomizer for one kind, comprise medicine-chest, it is characterized in that: medicine-chest and water pump are separately fixed on the underframe, medicine-chest is communicated with flowmeter by drug-feeding tube, be provided with the liquid control valve in the flowmeter bottom, the suction filter cartridge is communicated with flowmeter by water inlet pipe, and flowmeter is communicated with unit fixed on water pump suction by mixing the medicine water inlet pipe, exit of pump is communicated with spray gun by mixing the medicine outlet pipe, mixes the medicine outlet pipe and is communicated with medicine-chest by graduated release valve and time pencil simultaneously.

2. a kind of backwater motor atomizer of exempting from as claimed in claim 1 is characterized in that: regulate handle in suction and be provided with hand throttle, regulate line in suction and be provided with the backguy converter.
