Crawler trencher with adjustable trenching depth

Abstract

The invention discloses a crawler trencher with adjustable trenching depth. The crawler trencher comprises a rack, and a driver seat, an operation device, a hydraulic control device and a driving device are arranged on the rack. A walking transmission mechanism and walking crawlers are arranged under the rack, and the walking transmission mechanism is driven by the driving device to drive the walking crawlers to run. A chain transmission mechanism and a work spindle are arranged in the front of the rack, and a trenching cutter device is arranged on the work spindle. The work spindle is driven by the chain transmission mechanism to drive a trenching cutter of the trenching cutter device to rotate for trenching work. The chain transmission mechanism is connected with the driving device, and the work spindle is connected with the hydraulic control device through a hydraulic telescopic rod. The work spindle drives the trenching cutter device to fall and rise under the action of the hydraulic telescopic rod, and therefore the automatic adjustment of trenching depth is realized. The hydraulic control device and the driving device are connected with the operation device. The crawler trencher realizes simple and efficient linear trenching and the automatic adjustment of trenching depth, and is suitable for trenching work of various terrains, such as a terrain with a steep slope, an uneven terrain, etc.

Description

technical field [0001] The invention relates to a crawler type ditching machine with adjustable ditching depth, which belongs to the technical field of ditching mechanical equipment. Background technique [0002] my country is a country with a wide area of ​​plains, many hills, and relatively complex terrain. With the continuous improvement of people's requirements for the ecological environment and the continuous development of science and technology, the existing trenchers with a single function or a combination of several simple functions can no longer be used. To meet the needs of modern social production, its main defects are as follows: [0003] 1. For uneven land, the wheels of existing trenchers are prone to subsidence and deviation, resulting in uneven depth of the excavated drainage ditch and non-straight line of the drainage ditch, which will cause rainwater to be unable to drain from the ground. The ditch is discharged in time and the crops are drowned, which dir...

Problems solved by technology

[0002] my country is a country with a wide area of ​​plains, many hills, and relatively complex terrain. With the continuous improvement of people's requirements for the ecological environment and the continuous development of science and technology, the existing trenchers with a single function or a combination of several simple functions can no longer be used. To meet the needs of modern social production, its main defects are as follows:

[0003] 1. For uneven land, the wheels of existing trenchers are prone to subsidence and deviation, resulting in uneven depth of the excavated drainage ditch and non-straight line of the drainage ditch, which will cause rainwater to be unable to drain from the ground. The ditch is drained in time and the crops are drowned, which directly affects the growth and yield of the crops

[0004] 2. For the hilly areas where bamboo forests grow, the existing trenchers are prone to rollovers, or cannot perform climbing operations at all. Therefore, these areas can only rely on manual trenching, which has high labor intensity and low work efficiency. The quality of the excavated drainage ditches cannot be guaranteed

[0005] 3. Existing trenching machines cannot be constructed on roads, housing bases, etc., and can only be completed by large-scale engineering machinery and equipment or by manual methods, which is time-consuming and labor-intensive

[0006] 4. The trenching depth of the existing trenching machine cannot be automatically adjusted according to the actual construction needs. It needs to be shut down and adjusted manually. This adjustment method not only affects the trenching efficiency, slows down the progress of trenching, but also increases the labor of workers. Labor intensity and operating cost
