At this time, the first electric push rod will push the drill bit to continue working downward until it reaches the required depth. At the same time, the starting motor will also start and drive the shell to move forward through the pulley and belt transmission connection. While the shell moves forward, it will cooperate with the baffle plate, so that the loose soil blocks are transported to the backfill component for backfilling under the cooperation of the baffle plate and the shell. At the same time, the rolled cable on the support shaft will be laid and pulled along the groove. When the soil blocks are backfilled into the groove by the backfill component, the compacting component will work at the same time to compact the soil. When the rolled cable is used up, the cable can be replaced by rotating the knob, thereby achieving the purpose of traction and laying.

[0009] The above-mentioned technical solution is adopted. In this solution, when loose soil is transported to the backfill component, the first gear rotates. The rotation of the first gear will drive the backfill plate to move through the first rack and the second rack meshing with it. At this time, the symmetrically arranged backfill plates will move in the center and push the soil blocks on both sides into the groove. When the backfill plate moves, it will drive the spring fixed to it to move, so that the soil blocks in the movement process will be backfilled into the groove.

[0010] A further improvement of the technical solution of the utility model is that the compacting component includes a pressing plate, which is fixedly connected to the output end of the second electric push rod, the pressing plate is slidably connected to the shell, a third rack is fixedly connected to one side of the pressing plate, a second gear is rotatably connected to the partition, the second gear is fixedly connected to the first gear, and the second gear is meshed with the third rack.

[0011] The above-mentioned technical solution is adopted. In this solution, when compaction is required, the second electric push rod will start, pushing the pressure plate to move downward. The movement of the pressure plate will drive the third rack to move. The movement of the third rack will drive the second gear to rotate, thereby achieving the purpose of driving the first gear to rotate. This arrangement can make the soil compacted quickly after backfilling, speed up the working efficiency of the device and reduce labor costs.

[0012] A further improvement of the technical solution of the utility model is that a protective shell is fixedly connected to the partition, and the first rack and the second rack are respectively slidably connected to the protective shell.

This arrangement can greatly protect the stability of the device during operation, and at the same time effectively extend the service life of the parts.

[0014] A further improvement of the technical solution of the utility model is that: limit rollers are symmetrically arranged between the baffles and are rotatably connected.

[0015] By adopting the above technical solution, in which limiting rollers are arranged between the symmetrically arranged baffles, the laying direction of the cable can be changed, so that the cable will not affect the work of other components during the laying work.

[0016] A further improvement of the technical solution of the utility model is that a sliding door is rotatably connected to the shell body, a handle is fixedly connected to the sliding door, and the sliding door is made of transparent glass.

[0017] The above technical solution is adopted, in which the sliding door is made of transparent glass to facilitate the staff to observe the cable inventory in the shell in time, thereby improving the working efficiency of the device. If equipment failure, parts jamming, etc. occur, the staff can observe through the transparent glass door to allow timely discovery and take corresponding measures, thereby avoiding accidents.
