A pesticide sprayer for silage corn

Abstract

The invention discloses a pesticide sprayer for silage corn plants. The pesticide sprayer is characterized by comprising a telescopic sleeve assembly, a spiral pesticide liquid conduit, a spray head assembly, a hydraulic cylinder assembly, a fan cabin, a liquid storage tank, a battery cabin, a walking trolley assembly and a control assembly, wherein the periphery of the telescopic sleeve assemblywith blow holes in the left side and the right side is sleeved by the spiral pesticide liquid conduit; the hydraulic cylinder assembly is arranged inside the telescopic sleeve assembly. The pesticidesprayer has the beneficial effects as follows: the pesticide sprayer can not only reduce the labor burden of a spray implementer, but also improve the pesticide spraying efficiency, and can be also adapted to silage corn self-planting characteristics and plant characteristics, so as to achieve whole plant spraying.

Description

technical field [0001] The invention belongs to the technical field of crop spraying, in particular to a pesticide sprayer for silage corn. Background technique [0002] Silage corn, also known as fodder corn, is one of the three major corn types together with grain corn and fresh corn. This kind of corn has its own characteristics, mainly: it is necessary to harvest all green plants on the ground including ears; the height of the plants is relatively ordinary Edible corn is taller and has larger leaves than ordinary edible corn; the planting density is higher than ordinary edible corn. [0003] Due to the high planting density of silage corn, the row spacing and plant spacing of the plants are very small, and the height of the plants is mostly more than 3 meters, and the whole plant is used as feed, which requires spraying the whole plant with pesticides. At present, there is no specially designed pesticide The sprinkler can meet such spraying requirements: the existing pe...

AI Technical Summary

Problems solved by technology

[0003] Due to the high planting density of silage corn, the row spacing and plant spacing of the plants are very small, and the height of the plants is mostly more than 3 meters, and the whole plant is used as feed, which requires spraying the whole plant with pesticides. At present, there is no specially designed pesticide The sprinkler can meet such spraying requirements: the existing pesticide spraying devices are all simple backpack spraying devices, and such spraying devices have the following problems:

[0004] 1) It cannot meet the requirements of whole-plant spraying of high-plant silage corn. Once the spraying height exceeds 2 meters, the sprayer needs to lift the nozzle upward to spray the pesticide. In this case, it is very easy for the pesticide droplets to invade the sprayer's body. Eyes, mouth, and nose, causing potential health hazards for sprayers, and it is difficult for the maximum height of the spray to reach the top of the plant, which affects the spraying effect

[0005] 2) Since the row spacing of silage corn is very small, the spacing space is often inconvenient for the sprayer to carry the sprinkler on his back for spraying. In addition, due to the small spacing between plants, the leaves of adjacent plants usually overlap and cross each other, and a large number of covered leaves cannot be sprayed. When pesticides are sprayed, the existing spraying devices usually cannot reach the full coverage of the leaves

[0006] 3) The spraying efficiency is low, the spraying area per unit time is small, and the sprayer needs to carry the heavy liquid storage tank on his back, which will increase the possibility of physical damage to the bearer
