Efficient spraying machine special for machinery-picked cotton

Abstract

The invention discloses an efficient spraying machine special for machinery-picked cotton. The efficient spraying machine comprises a vehicle body, walking wheels arranged below the vehicle body, a plant divider installed on the outer sides of the walking wheels and cameras arranged on the vehicle body and located ahead of the walking wheels. The efficient spraying machine is convenient to operate; the plant divider is simple in structure and convenient to operate; the positions of plant-divider protecting plates arranged in front of the wheels of the cotton spraying machine can be conveniently and rapidly adjusted vertically, machinery damage to cotton plants is reduced, repeated disassembling is avoided, material resources and manpower are saved, and plant dividing and spraying efficiency is improved; due to high-speed rotating air flow generated by high-pressure air and spraying head bodies, liquid pesticide can penetrate through plant canopies, and the liquid applying rate of leaves can be greatly increased; the overall height of high-pressure spraying air bellows can be adjusted through a lifting hydraulic cylinder, and atomized liquid pesticide can be simultaneously sprayed onto roots, stems and the plant canopies of the machinery-picked cotton; the positions of plant-canopy spraying heads at the upper portions of the high-pressure spraying air bellows can be adjusted, and proper installation positions can be selected along with growth of cotton plants.

Description

technical field [0001] The invention belongs to the technical field of machine-picked cotton equipment, and in particular relates to a special high-efficiency sprayer for machine-picked cotton. Background technique [0002] my country is a large agricultural country with nearly 1.8 billion mu of arable land, and cotton is one of the main crops. At present, there are two forms of cotton planting: manual picking and machine picking. Machine picking cotton has obvious advantages in terms of picking input costs and comprehensive economic benefits. Whether it is artificially picked cotton or machine-picked cotton, it is necessary to spray drugs to prevent pests and diseases. The pests and diseases of machine-picked cotton are mainly three insects and two diseases, namely: cotton aphid, red and white spider, cotton bollworm, fusarium wilt, and verticillium wilt sick. Due to the large planting area of ​​machine-picked cotton, relying on manual backpack sprayers to spray pesticide...

Problems solved by technology

Due to the large planting area of ​​machine-picked cotton, relying on manual backpack sprayers to spray pesticides is inefficient

At present, the number of high-efficiency mobile plant protection machinery and equipment in my country is insufficient, and the level of mechanized plant protection operations is not high. Manual machinery still accounts for a large proportion of plant protection machinery in use. The phenomenon of "running, running, dripping, and leaking" is common, which affects the utilization rate of pesticides and the control effect. , It is easy to cause safety hazards such as environmental pollution, personal injury accidents and excessive pesticide residues

Some of the existing machine-picked cotton sprayers are simply powered by small four-wheel tractors, and carry out plant protection operations on cotton fields with spray boom sprayers, and some have introduced air curtain spray boom sprayers, self-propelled full hydraulic large-scale Boom sprayer, the spray effect is not good

The planting density in the machine-picked cotton area is high, and the existing air-curtain boom sprayers are all hydraulic first-level atomization, and the air-curtain-type air volume is very small, and the main canopy of machine-picked cotton cannot be sprayed through; the conventional self-propelled The full-hydraulic large-scale boom sprayer has the following problems: (1) At the cotton seedling stage, the control of cotton aphids can only be prevented by direct combat, and the control effect is not ideal, causing great harm to the growth of cotton seedlings. The spraying of micro-fertilizers cannot guarantee the liquid penetration rate on the back of the leaves, and the utilization rate of micro-fertilizers is low, which is not conducive to the rapid emergence of cotton seedlings; (2) the control effect on cotton red and white spiders in the middle and late stages is very poor, because Conventional boom sprayer has a very low liquid penetration rate on the back of the middle and lower leaves of cotton, and the ovicide cannot fully contact the body wall of the egg, so that the efficacy of the ovicide cannot be exerted; (3) Conventional boom sprayer The control effect on cotton bollworm in the middle and later stages is not ideal; (4) the defoliation effect is poor. The defoliation rate is about 60% after spraying the defoliation agent once. The cost will increase the cost and increase the mechanical damage rate

(5) Mechanized plant protection spraying equipment is mostly used for spraying and dusting, about 10 spraying operations per year, the rear wheel tires of large tractors are wide, the front wheel clearance is not high enough, the hanging spraying device installed on the spray boom, and the sealing line The rolling caused by the inability to walk in a straight line will cause about 8% of the mechanical damage to the machine-picked cotton, which will affect the growth of cotton and cause economic losses; It is short, the protective plate has a high clearance, the effect of grain separation is poor, and the mechanical damage is serious. If it is installed in advance, the protective plate will drag the ground during the process of spraying, causing a missed machine. The grain separating protective plate can only be added when it reaches the field. installed, then disassembled during transfer, low efficiency
