Steering mechanism of a self-propelled fruit forest machine

Abstract

The invention relates to a steering mechanism of a self-walking fruit forest machine. The steering mechanism of the self-walking fruit forest machine comprises a rear vehicle frame, a front vehicle frame and a steering device connected between the rear vehicle frame and the front vehicle frame. The steering mechanism of the self-walking fruit forest machine is characterized in that the steering device comprises a rear steering joint and a front steering joint, the front steering joint is fixedly connected with the front vehicle frame, the rear steering joint is connected with the rear vehicle frame in a rotary mode, the rear steering joint and the front steering joint are hinged through a main rotating pin, and a pair of steering oil cylinders are symmetrically arranged at the two sides of the main rotating pin. The steering mechanism of the self-walking fruit forest machine has the advantages of being flexible in steering, not prone to being turned over and capable of effective eliminating the vehicle frame torsion.

Description

technical field [0001] The invention relates to a plant protection machine, in particular to a steering mechanism of a self-propelled orchard machine. Background technique [0002] Spraying economic crops is one of the means of economical and effective plant protection. The purpose is to eliminate diseases, insects, weeds and other harmful organisms before they are harmed and prevent them from causing disasters. For large-scale operations, the use of large and medium-sized sprayers is the main development trend. Present sprayer kind is more, preferably self-propelled type, promptly has front frame and rear frame, is provided with steering mechanism between front frame and rear frame. The steering mechanism of the current similar machines is generally relatively simple, that is, the front and rear steering connecting plates are directly fixed on the front and rear racks, and a pin shaft is used to connect them. Steer cylinder. This structure has the following defects: Firs...

AI Technical Summary

Problems solved by technology

This structure has the following defects: First, due to the uneven ground when the sprayer is in operation, it is easy to cause the twisting of the front and rear frame, and the rigid connection between the front and rear steering connecting plates cannot effectively eliminate the torsion, which may easily lead to wear and tear of the pin shaft. It will also cause hard damage to the frame; the second is that due to the single-sided steering cylinder, it is easy to cause the front frame to twist and fall suddenly when turning, and then cause damage, and the steering push-pull torque of a single cylinder varies greatly, which increases the driver's Difficult to operate; third, due to the need for hydraulic power transmission between the front and rear frames, multiple hydraulic pipes need to pass through the steering mechanism, and this steering mechanism often causes wear and tear on the hydraulic oil pipes during steering, making the machine failure rate improve
