Multi-adaptive self-propelled chemical spraying vehicle

Abstract

The invention discloses a multi-adaptive self-propelled chemical spraying vehicle, and relates to agricultural machinery. The vehicle includes a support frame provided with four wheels, and an overall frame used for mounting an engine, a gearbox, a fuel tank and a driving cab; the bottom of the overall frame is arranged below the lower cross beams of the support frame; a hydraulic cylinder is vertically mounted between the support frame and the overall frame and used for adjusting the height of the overall frame relative to the support frame; the support frame is a hollow support frame in the overhead view direction; the overall frame is narrower than the support frame in the left-right direction, and is longer than the support frame in the front-rear direction; the four wheels are mounted at the parts, longer than the overall frame in the left-right direction, of the support frame front and back; the engine, the gearbox and the fuel tank are mounted on the overall frame at the hollow position of the support frame; the driving cab is mounted at the part, longer than the support frame at the front part, of the overall frame. According the invention, the height of the overall frame can be adjusted according to the height of the crop straw, so that not only is the damage to the crops reduced, but also the center of gravity of the overall vehicle is lowered, and the overturning probability is reduced.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a self-propelled medicine spraying vehicle. Background technique [0002] The self-propelled spraying vehicle is an agricultural vehicle for spraying pesticides on crops. The existing self-propelled spraying vehicles still have the following defects or functions that need to be improved: 1. In order to adapt to field operations in the middle and late stages of growth of high-stalk crops such as cotton, corn, and sugar cane, the chassis of the existing self-propelled spraying vehicles is set to Relatively high, the engine, gearbox and fuel tank are located at the high position of the vehicle body, resulting in the center of gravity of the vehicle is always at a high position; and the terrain in the field is very complicated, resulting in potential safety hazards of dumping and overturning during the driving and operation of the self-propelled spraying vehicle . 2. The distance between ...

Problems solved by technology

3. The terrain of the self-propelled spraying vehicle is complex and varied, and the types of crops are also diverse; the two-wheel steering system is not suitable for farmland operations due to its large steering radius; the four-wheel steering system usually uses mechanical transmission and has a complex structure. It is more difficult to realize the vehicle type whose wheelbase needs to be changed or the working environment where the terrain height changes greatly; some hydraulically driven four-wheel steering systems have poor steering stability due to their structure or oil circuit problems, and it is difficult to maintain after losing the driving oil pressure.
