Abstract

The utility model relates to a hand-push type pesticide sprayer, comprising a pesticide box which is fixedly arranged on a handcart. A pesticide cylinder outlet arranged at the upper part of the pesticide box is connected with a spray head by a perfusion tube, and a front chain wheel and a rear chain wheel of the handcart are connected by a chain. The rear chain wheel uses a clutching transmission system to drive a pressing rod to let a pump piston rod on the pesticide box to work, and a dialing device installed on a handlebar is used for controlling the clutching action of the transmission system and the action of a spraying switch. With convenient use, the sprayer can reduce labor intensity, improve work efficiency and spraying quality, and can avoid solution poisoning to affect human body health.

Description

The hand propelled pesticide sprayer

Technical field

The utility model relates to a kind of hand propelled pesticide sprayer, belongs to agricultural equipment.

Background technology

When using existing pesticide sprayer to spray insecticide, the operator backs on the body medicine-chest, and its shortcoming is that capacity is little, and labour intensity is big, inefficiency, and manual sprinkling is inhomogeneous, and it is unhealthful also to leak soup easily.

Summary of the invention

The purpose of this utility model provides a kind of hand propelled pesticide sprayer, and it can reduce labor intensity, and increases work efficiency and sprays quality.

The technical solution of the utility model is: the hand propelled pesticide sprayer, has medicine-chest, it is characterized in that: medicine-chest is packed on the handcart, the cartridge case outlet that is located at medicine-chest top is connected with shower nozzle by woven hose, cartridge nozzle is at the vehicle frame front end, woven hose is provided with spray medicine switch, spanner one side of spray medicine switch is connected with the reset tension spring on being fixed on vehicle frame, opposite side is connected with spray medicine striking device on being packed in handlebar by backguy, the preceding sprocket wheel that is connected with wheel is housed on the axletree of vehicle frame front portion, rear axle and vehicle frame are connected, the back sprocket wheel of flexible connection is housed on the rear axle, before, between back sprocket wheel chain is housed, the axle sleeve of flexible connection also is housed on the rear axle, an end and clutch are connected on the axle sleeve, the double wedge that is located at the clutch end face places the jack on the Chain wheel plate of back, the axle sleeve other end and eccentric wheel are connected, spring is housed in the eccentric wheel, spring housing is contained in the back shaft end, the eccentric wheel outside is hinged with depression bar, air cylinder piston rod on the depression bar other end and the medicine-chest is hinged, on the axle sleeve between clutch and the eccentric wheel, be provided with thumb wheel, the shift fork one end hinged with vehicle frame is provided with the spill gap, the outer ring wheel disc of thumb wheel places the spill gap, and the shift fork other end is connected by backguy and the clutch striking device that is contained on the handlebar.

The advantage of present technique is: 1, be installed on the handcart owing to pesticide box, so more laborsaving and convenient than personnel selection back of the body medicine-chest with handcart band case medicine; 2, explosive payload is many, does not need to fill medicine midway, and has saved the time that turns back to the soup storage from the field; 3, owing to manually control spray medicine automatically on handlebar, medicine-chest is away from human body, so avoided intoxicating phenomenon; 4, spray medicine wide coverage sprays evenly, has improved sprinkling quality and operating efficiency, saves soup than prior art.
