Excavating and cable-paving integrated machine

Abstract

The invention discloses an excavating and cable-paving integrated machine. The excavating and cable-paving integrated machine comprises a driving machine base, a knife chain type furrow opener, a balancing turnplate driving bearing, two lifting turnplate driving bearings, a back-filling device and a cable conveying guide wheel, wherein the balancing turnplate driving bearing is arranged on the front part of the driving machine base; the cable conveying guide wheel is arranged at the top of a housing of the balancing turnplate driving bearing; the two lifting turnplate driving bearings are fixedly arranged on the inner walls on two sides of the driving machine base; the knife chain type furrow opener is arranged on the driving machine base; and the back-filling device comprises a back-filling bracket, a back-filling scraper plate, a vibrator and two back-filling turnplate driving bearings. The invention has the advantages that the excavating and cable-paving integrated machine has a simple and compact structure and is easy to assemble and maintain; electromechanical-hydraulic integration, standardization, modular combination and automation control of the whole machine are realized; and the whole machine is easy in coordination control. According to different soil qualities and depths, speed can be adjusted freely, and furrow opening, cable laying and back filling can be finished in one step.

Description

Technical field: [0001] The invention relates to an excavating machine, in particular to an excavating and laying cable integrated machine. Background technique: [0002] In the existing cable trenching and laying project, trenching is first performed with a trencher, then cable is buried, and finally backfilling and ground restoration are performed. Time-consuming, labor-intensive, and labor-intensive, increase construction costs, and cannot meet the needs of cable burying facilities. [0003] After the current opener is installed on a tractor, the take-off and landing of the knife chain is mostly done by hydraulic cylinders, and the take-off and landing range is limited to a certain extent. The ditching depth is controlled by the movement of the cylinder to change the direction of the opener arm’s overturning angle. Lifting, this method has a dead center position. In addition, the layout of the hydraulic lifting arm must be considered when assembled on the tractor. During operat...

Problems solved by technology

Time-consuming, labor-intensive, and labor-intensive, which increases construction costs and cannot meet the needs of cable embedding construction

[0003] The current opener is installed behind the tractor, and most of the lifting and lowering methods of the knife chain are completed by hydraulic cylinders, and the lifting range is limited to a certain extent. The opening depth is determined by changing the direction of the overturning angle of the opener arm by controlling the movement of the oil cylinder. Lifting, there is a dead point in this way. In addition, the layout of the hydraulic lift arm space must be considered when assembling on the tractor. During operation, the opener is connected with the tractor as a whole. The trench dug by the general trench digging machine or trench digging and cable laying machine cannot guarantee that its two walls are perpendicular to the horizontal plane.

[0004] The cable laying is done manually, which is not coordinated with the tractor, which is easy to damage the cable and the laying efficiency is low. When laying multiple cables at the same time, it is difficult for the existing cable laying machine to transport the cables manually and coordinately. , and consume manpower to increase cost

[0005] When the ground is backfilled, the soil cut out by the opener is not backfilled solidly, and it is difficult to restore the landform before trenching
