[0047] The use process and working principle of this device:

[0048] The equipment is moved to the location where the cable trench is to be operated. According to the backfill location, the construction personnel input an adjustment signal to the control unit to adjust the relative position of the shovel assembly 3 and the backfill location;

[0049] The control and adjustment motor starts, the driving gear 38, the driven gear 37 and the soil loading mechanism rotate, and the backfill soil is transported to the transmission belt 23 through the conveying ramp 35. The control unit controls the driving motor and the reduction motor 46 to rotate, so that the telescopic conveyor 2 transports the backfill soil that slides onto the transmission belt 23, and the soil crushing pieces 42 in the crushing assembly 4 rotate to crush the soil blocks in the backfill soil transported to the vehicle body 11, and the crushed backfill soil falls into the backfill position in the cable trench;

The telescopic end of the lifting and telescopic cylinder 55 shortens, driving the lifting plate 52, the angle-adjusting telescopic cylinder 53 and the scraper 51 to move downward, so that the scraper 51 contacts the backfill soil. At the same time, the telescopic end of the angle-adjusting telescopic cylinder 53 extends, so that the angle between the scraper 51 and the horizontal plane is adjusted to a suitable size to ensure that the extension of the angle-adjusting telescopic cylinder 53 is fixed, so that the scraper 51 performs a leveling operation until the backfill soil is leveled.

[0051] The rotating motor 63 is adjusted to start, and the output shaft of the rotating motor 63 drives the through shaft 62 and the rotating member 64 to rotate, and the moving section 662 on the matching member 66 in each tamping unit moves along the track of the wave groove 641, and at the same time, drives the lifting section 661 to move vertically back and forth along the moving groove 611, so that the tamping plates 67 in the four tamping units tampe the backfill soil at the backfill position in turn to tamp the soil;

[0052] Finally, check the quality of the work and proceed with follow-up work after it is accepted.

[0053] The present invention provides a compaction device for backfilling a cable trench. The backfill soil is excavated and transported through the cooperation of a shovel assembly 3, a telescopic transmission machine 2 and a crushing assembly 4. The larger soil blocks are crushed and then transported to the cable trench. The crushed soil particles become smaller, and the gaps between the soil blocks are reduced after landfilling, so that the foundation is not easy to loosen. At the same time, the telescopic transmission machine 2 adopts a telescopic transmission mechanism, which can move the shovel assembly 3 to a suitable position according to the soil position on both sides of the cable trench, so as to facilitate the transportation of backfill soil over a long distance and meet the needs of large-scale and high-efficiency construction.

[0054] The present invention provides a tamping device for backfilling a cable trench, wherein the tamping assembly 6 includes four tamping units, and four tamping plates 67 are tamped in sequence. The four tamping plates 67 are in contact with the backfill soil to form four tamping points, so that the compacted soil is formed more evenly and is denser after landfill, which helps to increase the bearing capacity of the foundation, so that it can withstand greater loads without settlement or deformation, and also helps to save construction time and thus shorten the construction period.

[0055] The present invention provides a tamping device for backfilling a cable trench. The device can be overall controlled by an embedded control unit to avoid construction workers tamping with handheld equipment, save manpower input, reduce workers' labor intensity, and is not prone to overlap with other operations. At the same time, the device can synchronize backfilling operations with tamping operations to avoid safety hazards and impact on other construction caused by untimely backfilling, thereby effectively accelerating the efficiency of cable trench backfilling construction.
