Problems solved by technology

Moreover, in case of hard objects such as stones, it is impossible to dig down, and the chain knife is very easy to wear and damage. If it is damaged, a chain knife needs to be replaced, which is expensive and troublesome to operate.
The earth-discharging auger is usually installed on the main shaft of the chain knife, and its action moves up and down with the chain knife, which is inconvenient to use

Embodiment Construction

[0011] The structure of the present invention will be described in detail in conjunction with the accompanying drawings.

[0012] A small chain trencher such as figure 1 As shown, on the small-sized rubber crawler locomotive 1, the locomotive engine 2, the walking control handle, the hydraulic pump and the hydraulic pump control handle are housed as usual, and the hydraulic pump oil delivery pipe connects the hydraulic cylinder. A ditch opener 4 is installed on one side of the small crawler locomotive 1, and is connected with each component by being contained in the hydraulic cylinder fixed bracket 3 of the small crawler locomotive 1: a base frame 8 is installed on the small crawler locomotive 1, and a base frame Prop 11 is housed on 8, hydraulic cylinder fixed support 3 is installed flexibly at the top of support 11, and hydraulic cylinder fixed support 3 two ends can carry out lifting activity with hydraulic rod telescopic on prop 11. One end of the hydraulic cylinder fixin...

Abstract

A small-sized chain trencher is provided with an opener on a small-sized crawler travel locomotive. The opener is provided with a ditching claw-plate and a plate with on an opener chain at intervals; the lifting of the opener chain is controlled by a hydraulic cylinder; the lifting of a packing auger oil transmission device is controlled by a separate hydraulic cylinder. The travelling gear of the invention adopts the small-sized crawler travel locomotive which has small volume, light weight, small turning radius, good grade climbing performance, and is suitable for being operated in small space or sloping filed orchard areas; the two hydraulic cylinders control the lifting of a transmission shaft of the opener and causes the transmission shaft to run smoothly and safely. A ditching claw replaces a universal chain ditcher, not only has high strength and is difficult to be damaged, but also is convenient for being replaced and easy to be maintained; the ditching claw touches the ground by points, has great force, high efficiency; a packing auger is provided with the hydraulic cylinder to cause the packing auger oil transmission device to completely and independently control the lifting; therefore, the small-sized chain trencher is convenient to use.

Description

technical field [0001] The invention relates to an agricultural machinery, in particular to a ditching machine. Background technique [0002] Trenchers are commonly used construction machinery for laying pipelines and cables. This kind of construction machinery has different models such as shovel trenchers, bucket wheel excavators, and chain trenchers. It is suitable for digging trenches above 50cm. This kind of trencher has complex structure, high cost, and inconvenient movement, so it is not suitable for trenches with narrow width and shallow depth in orchard excavation. [0003] Small trenchers mainly contain two types at present, and one is an auger type, such as ZL96231550.8, and the other is a chain trencher, such as the disclosed chain trencher in Chinese Patent Application No. 200710068041.4. Small trenchers are usually installed on walking tractors. This kind of walking device has a large body width and a large turning radius. It has poor adaptability to work areas...
