Power chassis for orchards on mountains and hills

Abstract

The invention discloses a power chassis for orchards on mountains and hills. The power chassis comprises a rack, an engine, a gearbox, a left wheel set, a right wheel set, a height difference adjusting device and a ground clearance adjusting mechanism. The engine and the gearbox are connected to the upper portion of the rack, the left wheel set and the right wheel set are connected to the two sides of the rack respectively, and the height difference adjusting device is connected to the left wheel set and the right wheel set through a parallel four-connecting-rod mechanism. The ground clearance adjusting mechanism comprises a ground clearance adjusting oil cylinder fixedly connected to the gearbox, and the axial stretching end of the ground clearance adjusting oil cylinder is connected to the height difference adjusting device. The height of left wheels and right wheels of the power chassis can adapt to the ground slope, the ground clearance can be adjusted, the passage capacity is good, and the power chassis is especially suitable for working under short fruit trees and on uneven grounds. In the work process, when the chassis walks on a cross slope, the height difference adjusting device adjusts the height difference of the left wheels and the right wheels immediately, and the chassis is restored to the horizontal state.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a power chassis that can drive related agricultural machinery to carry out operations such as rotary tillage, weeding, pesticide spraying, fertilization, ditching, and transportation in slope or flat orchards. Background technique [0002] The existing orchard operating power either adopts a hand-held field management machine, or adopts a four-wheel tractor with medium and small horsepower. If these two types of power are under normal conditions, their operation is quite convenient. If there is a corresponding problem in the orchard operation, if the fruit trees are relatively short, not only is it inconvenient for personnel to walk during operation, but also ordinary four-wheel tractors cannot enter under the orchard trees to perform operations. Especially when working in orchards in mountainous and hilly areas, these two types of power are not only not suitable...

AI Technical Summary

Problems solved by technology

If you work in an orchard, there will be corresponding problems. If the fruit trees are relatively short, not only will it be inconvenient for people to walk during operation, but also ordinary four-wheel tractors will not be able to work under the orchard trees.

Especially when working in orchards in mountainous and hilly areas, these two types of power are not only not suitable for working under fruit trees, but also have poor passability, and are not suitable for working on sloped ground.

Although tractors with hydraulically variable ground gaps have appeared in the existing market, they have poor passability and are inconvenient to operate. Therefore, it is necessary to research and develop a tractor with better passability, suitable for orchard operations, and can be controlled by remote control.
