Variable amplitude spraying machine

Abstract

The invention discloses a variable amplitude spraying machine. The spraying machine comprises a handcart with travelling wheels, a liquid medicine tank, a petrol engine, a water pump, a vertical bracket, a horizontal bracket, spraying devices, a lifting device and recycling devices, wherein the liquid medicine tank, petrol engine and water pump are arranged on the chassis of the handcart, the vertical bracket is arranged on the front end of the handcart, the horizontal bracket is connected with the vertical bracket through a slider, the horizontal bracket is connected with a plurality of spraying devices and recycling devices, the spraying devices and the recycling devices are arranged symmetrically, the horizontal strut in the middle of each two adjacent spraying devices is provided with a hollow conical spray head, and the lifting device is connected with the horizontal strut. The spraying machine of the invention can be adjusted according to the height and line spacing of grapes or other corps growing on trellis, and collect the liquid medicine which can not hit grapes and blow in air and filtrate the collected liquid medicine for reuse so as to increase the utilization of the pesticides and reduce the damage of chemical pesticides to the personnel safety of operators and the environmental pollution.

Description

[0001] the field [0002] The invention belongs to the field of agricultural machinery, and relates to a sprayer, in particular to an amplitude-changing sprayer. Background technique [0003] There are many diseases and insect pests in grapes planted in the open air, and it needs to be sprayed once every 10 to 15 days. If it rains after spraying, it needs to be sprayed again, and pesticides need to be sprayed more than ten times a year. The purpose of using pesticides to control crop diseases, insect pests and weeds is to use the least amount of pesticides to achieve the best control effect without causing negative effects such as human and animal poisoning and environmental pollution. But in fact, only a very small part of the sprayed pesticides can reach the targets to be controlled. Studies have shown that only 25% to 50% of the pesticides sprayed from the spraying equipment can be deposited on the crop leaves, and most of the pesticides are lost. Drifting into the environ...

AI Technical Summary

Problems solved by technology

[0004] The application of liquid recovery and recycling technology has not been seen in the existing vineyard sprayers, and the boom of the sprayer cannot be adjusted in a timely and convenient manner according to the height and row spacing of grapes or other trellis crops, resulting in a limited range of applications
