Description

Hydraulic self-propelled cotton field high clearance spraying vehicle

technical field

The invention relates to an agricultural chemical spraying vehicle, in particular to a hydraulic self-propelled high-gap chemical spraying vehicle for cotton fields.

Background technique

In the management of cotton fields, in order to prevent the occurrence of diseases and insect pests and ensure the normal growth of cotton, it is necessary to spray pesticides. In view of the current rural cotton planting in our country, young and middle-aged laborers go out to work, and the left-behind farmers are too old. Manual spraying still uses a medicine box on the back and a spraying rod for spraying. It is inconvenient to operate, labor-intensive, time-consuming, high in cost, and low in spraying efficiency. . Existing agricultural machinery generally has a low chassis, and the wheel base is fixed or limited in adjustment. The cotton plant height and row spacing are affected by the cotton plant height and row spacing in the later stage of cotton growth. It has caused destructive effects on cotton plants, and field spraying can only be completed by manual spraying operations.

The drug inlet pipe and the return pipe of the triple pump are connected with the liquid medicine tank, and the drug outlet pipe of the triple pump is connected with the nozzle.

During operation, the diesel engine drives the pulley II to rotate, and the pulley II drives the pulley I and the hydraulic oil pump to work, so that the oil in the hydraulic oil tank is output to the hydraulic motor through the hydraulic distributor, and the hydraulic motor drives the front drive wheel to walk through the chain drive; at the same time, the diesel engine Drive the pulley II to rotate, drive the pulley I and the hydraulic oil pump to work, output the oil in the hydraulic oil tank to the steering oil cylinder through the steering gear, and the steering wheel will turn after the steering oil cylinder is pushed; the diesel engine drives the pulley II to rotate, drives the pulley III, and the triple pump to work, triple The pump sprays the liquid medicine in the liquid medicine tank through the medicine outlet pipe and the nozzle, which overcomes the problems of time-consuming and labor-intensive spraying with a hand-held spray rod and poor spraying effect in the prior art.

The left and right sides and the rear side of the frame are fixed with hooks, and the front outer thick arm tube and the rear outer thick arm tube connected with the hook on the rear side of the frame are arranged under the frame, and the left and right sides of the front outer thick arm tube are The front inner thick arm tube connected with the front driving wheel is covered, the left and right sides of the rear outer thick arm tube are covered with the rear inner thick arm tube connected with the rear steering wheel, the front inner thick arm tube and the rear inner thick arm tube are covered All are connected with a hydraulic oil cylinder communicated with the steering gear.

When the wheel base is adjusted, the diesel engine drives the pulley II to rotate, thereby driving the pulley I and the hydraulic oil pump to work, and outputs to the hydraulic cylinder through the hydraulic distributor, and the hydraulic cylinder drives the front and rear inner thick arm tubes to expand and contract in the front and rear outer thick arm tubes to realize Adjustment of the distance between the front drive wheels and the distance between the rear steering wheels.

The spraying arm is made of several joints of the spraying arm body, and the two ends of the spraying arm are connected with the hooks on the left and right sides of the frame; The arm is fixed to the guide rod, and the outer side of the guide sleeve is screwed with locking bolts.

The height between the ground and the spraying arm is realized by adjusting the height of the guide rod through the locking bolt.

The vertical distance between the frame and the ground is greater than or equal to 100cm, and the distance between the front driving wheels and the rear steering wheels is 40cm.

The structure design of the invention is reasonable and reliable, and the wheel base and height can be adjusted according to the row spacing of the cotton field planting rows, which ensures that the wheels and the chassis will not scratch or scratch the cotton plants, saves time and effort, and improves work efficiency at the same time. It has a simple and compact structure. , Easy to operate and low cost.
