Portable instant pesticide flow controlling spray gun

Abstract

The invention discloses a portable pesticide flow control type spray gun, which includes a spray head and a casing, the casing includes a gun handle casing and a gun bore casing; a trigger linkage mechanism and a spray mechanism are arranged in the casing, and the trigger linkage mechanism includes a hinged driven The connecting rod and the trigger connecting rod, the trigger connecting rod is composed of the connecting rod and the trigger, and a trigger fulcrum shaft is arranged at the junction of the connecting rod and the trigger; the injection mechanism includes a sprocket covered with a chain, and one end of the chain is fixed on the teeth of the sprocket, The other end bypasses the sprocket and connects with the piston through the piston shaft passing through the sliding bearing. One end of the jet spring is fixed on the left side of the sliding bearing, and the other end of the jet spring is connected with the jet spring fixing block; On the mandrel of the spring, one end of the torsion spring is fixedly connected with the torsion spring fixed cylinder, and the spring wire at the other end passes through the torsion connecting rod and is connected with the driven connecting rod, and the torsion spring fixed cylinder is fixedly connected with the inner wall of the handle shell. The spray gun can control the flow rate and spray speed of the pesticide in real time, so that the pesticide water can be prepared and used immediately.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, in particular to a spray gun for spraying pesticides. Background technique [0002] In agricultural production, pesticides are indispensable for weeding and pest control. There are many types of pesticide spraying equipment, which can quickly spray pesticides on large areas of crops, but the spraying of pesticides cannot control the uniformity of spraying, because When spraying pesticides with existing spray guns, the spraying speed (pressure) of the pesticides is often constant, which results in a certain sprayed area range, and in the process of spraying pesticides, the height and distance between the operator or the spray gun and the crops are all the same. Not necessarily, if the spray gun is too close to the crops, most of the pesticides may be sprayed directly out of the crops when spraying, resulting in waste of pesticides, or repeated spraying of adjacent crops, insufficien...

[0002] In agricultural production, pesticides are indispensable for weeding and pest control. There are many types of pesticide spraying equipment, which can quickly spray pesticides on large areas of crops, but the spraying of pesticides cannot control the uniformity of spraying, because When spraying pesticides with existing spray guns, the speed (pressure) of spraying pesticides is often constant, which results in a certain range of sprayed areas. In the process of spraying pesticides, the height and distance between the operator or the spray gun and the crops are different. Not necessarily, if the spray gun is too close to the crops, most of the pesticides may be sprayed directly out of the crops when spraying, resulting in waste of pesticides, or repeated spraying of adjacent crops, insufficient or excessive spraying of pesticides will seriously affect the quality of crops Growth and harvest, especially for some precious crops with high economic value and low output, improper spraying of pesticides will directly cause irreparable economic losses
