Orchard trencher

Abstract

The invention relates to an orchard ditching machine which is characterized by comprising a machine frame (15), an engine (3) and an operation system (4). The engine is arranged at the front portion of the machine frame, a track traveling device (1) and a hydrostatic transmission (HST) (2) are adopted, a ditching device (13) is an inclined swing suspension type, arranged on the rear portion of the machine frame and installed on a swing support (10) with a gearbox (12), the swing support is connected with a fixing support (14) through a hinge, power of the engine is transmitted to the ditching device through belt transmission (8), chain transmission (11) and the gearbox (12), and a lifting oil cylinder (9) controls the depth of ditching operation. The orchard ditching machine ditches gradually, is small in working resistance and good in operation stability of the whole machine, achieves comprehensive control of traveling driving and a working device, and is good in economy and power performance, easy to control and capable of meeting operation environment requirements of orchard ditching.

Description

technical field [0001] The invention relates to a ditching machine for orchards, in particular to a ditching machine suitable for ditching operations in orchards on sloping and flat lands. Background technique [0002] Orchard ditching is one of the important links in orchard production. Most of the trenching operations are on hard slopes, with large operation width and depth, and large resistance during operation. When ditching, it is necessary to work while walking, and the traveling device and the working device move at the same time. The ditching operation requires a low-speed and large driving force, while the transfer speed is relatively high, so the required driving force and speed vary widely. At present, most domestic trenchers are matched with tractors, adopt wheeled chassis platforms, and use mechanical gearboxes. The ditching machine in this way has the following disadvantages: 1) Since the wheeled chassis structure is mostly suitable for flat places, its own s...

AI Technical Summary

Problems solved by technology

This type of ditching machine has the following disadvantages: 1) Since the wheeled chassis structure is mostly suitable for flat places, its own stability is poor, and it is difficult to adapt to the ditching operation environment of sloping orchards

2) The use of mechanical transmissions cannot adapt to the large load changes and harsh environments during ditching operations, and the engine power cannot be fully utilized, resulting in low operating efficiency, frequent shifting of gears during operations, and high labor intensity for drivers

Therefore, at present, the ditching of orchards is almost still done manually, which is time-consuming, labor-intensive, labor-intensive, and inefficient.
