[0007] The rotating shaft is rotatably connected to a cover shell covering the spiral sheet, a through hole is provided on the top of the cover shell, and a soil pouring trough is connected to the cover shell at the position of the through hole;

[0008] The soil pouring trough is inclined with respect to the horizontal plane, and the inclination angle of the soil pouring trough is smaller than the rotating shaft, so that a gap is formed between the soil pouring trough and the cover shell;

[0009] The pipeline reel is provided with a hose or a cable, and the hose or the cable enters the excavated trench through the gap and is laid, and then is buried by the broken soil that slides down from the soil pouring chute.

[0010] Furthermore, the support frame includes two parallel support plates, the tops of the support plates are hinged to the rotating shaft, and the support plates are tilted backwards.

[0011] Furthermore, the width of the cover shell and the soil pouring trough is not greater than the total width of the two rotating shaft spiral pieces;

[0018] When working, the carrying platform moves on the set route, the hydraulic pump drives the hydraulic motor, the hydraulic motor drives the rotating shaft, and drives the spiral blade to dig the soil. When the spiral blade digs the soil, it will dig the broken soil between it and the cover, and continuously transport the broken soil to the through hole. When the broken soil reaches the through hole, it will overflow into the soil pouring chute.

[0019] When the spiral blade digs the trench, the hose or cable on the cable drum is laid into the trench through the gap above the cover. Then the broken soil in the pouring trough will bury the hose or cable under the soil.

[0020] The inclination sensor senses the inclination and enables the control system to adjust the power of the hydraulic pump and the travel speed of the carrying platform to ensure consistent groove depth.

[0021] The beneficial effects of this scheme can be seen from the description of the above scheme. The structure is simple and the design is reasonable. (1) The spiral blades dig and transport the crushed soil at the same time, so that the work continuity is good and the digging efficiency is high, thus ensuring the overall work efficiency is high. (2) In addition, with the function of the inclination sensor, it is easy to ensure the uniform depth of the trench, so that the pipeline laying depth is easy to control. (3) Excavation, laying and landfilling are carried out in one, thus avoiding the formation of trenches for a long time, affecting traffic and environmental sanitation. (4) The hydraulic motor is used to drive the excavation because the hydraulic motor has good impact resistance. BRIEF DESCRIPTION OF THE DRAWINGS
