[0026] Working principle: In the actual design process of the present invention, in order to avoid the following defects existing in the prior art: "In the prior art, in the process of burying the cable, an excavator is first used to dig out a buried groove, and then the cable is laid inside the foundation pit by pulling the cable on the drum with a traction machine. Finally, the foundation pit is buried to achieve the effect of the entire laying. However, the cable laying process of the prior art has the following technical defects: after the cable is pre-laid, the excavated mud and sand cannot be backfilled in time, but is subsequently backfilled by an excavator, which will lead to a decrease in the efficiency of backfilling and cannot ensure that the cable is pre-buried in time." The excavation component 2, the laying component 201, the foundation pit moving component 3 and the synchronous gathering pre-buried component 4 are specifically proposed; Mining Component 2: In the actual process of laying cables, it is first necessary to excavate a foundation pit. In the prior art, the actual excavation depth of farmland is ≥1 meter; the excavation depth of ordinary roads is ≥0.7 meters. Therefore, we need to pre-adjust the excavation angle and depth of the bucket 7 to adapt to the above technical requirements. We can control the rocker arm 5 to rotate on the surface of the N-shaped frame 501 through the first motor 6 to achieve large angle and depth adjustment, and then control the bucket 7 to rotate on the surface of the shaft 36 through the second motor 8 to adjust the small angle and small depth. After the adjustment is completed, the locking pieces 9 at both ends need to be tightened respectively to ensure the accuracy of positioning. After the angle adjustment is completed, preparations for excavation are ready. The power source inside the frame 1 controls the movement of the frame 1, and then the bucket 7 is used to achieve the excavation effect.

[0027] Laying component 201: The laying component 201 is synchronously arranged behind the excavation component 2, achieving the effect of immediate laying. The double-headed motor 12 controls the rotation of the drum 13, and the drum 13 can convey the cable 14 to the sleeve 16 of the bracket 15 during the rotation process to achieve limited positioning. The cable is finally conveyed to a specific part of the foundation pit under the protection of the bushing 19 and the protective cover 17. This equipment achieves the effect of synchronous positioning and pre-embedding, avoiding the problem of reduced positioning accuracy caused by pulling and repositioning in the prior art.

[0028] Pit moving component 3: The foundation pit moving component 3 achieves the dual effects of positioning and moving the device above the foundation pit. It can prevent the equipment from falling into the inside of the foundation pit and can also serve as an auxiliary positioning structure for foundation pit excavation. The transmission wheels 21 on both sides drive the crawler tracks 22 to move around the periphery of the foundation pit under the action of the power source. A certain amount of soil passing space needs to be reserved between the foundation pit and the crawler tracks 22 to prevent the turned-up soil from blocking the movement of the equipment. The crawler track 22 structure simulates a tank device to ensure the stability of operation. In addition, the auxiliary wheel 33 can also modulate the crawler track 22 to ensure the stability of operation.

[0029] Synchronous gathering embedded component 4: The advantage of this component is that it synchronously utilizes the power source of the cable output drum as power, and inputs power to the auger shaft through the belt 28 transmission structure, and the auger 26 set in opposite directions on both sides just falls on the excavated mud and sand. Through the rotation of the auger 26, the mud and sand can be synchronously buried on the surface of the cable 14, achieving the effect of real-time backfilling and pre-embedding, which is a creative transformation and utilization of the drum power source. In addition, the auger 26 structure is set as an inner rotation structure with a large outer side and a small inner side. This structure can well rotate the mud and sand accumulated on the periphery into the interior of the foundation pit, avoiding mud and sand residue.

[0030] In summary, this cable laying equipment achieves the integrated effect of foundation pit excavation, cable laying and mud backfilling, greatly improving the efficiency of the process. The synchronous backfilling structure creatively utilizes the power structure of the drum to achieve the effect of power steering and guided backfilling. One machine has multiple uses and significant efficiency.

[0031] The present invention pre-adjusts the installation angle of the bucket 7 by setting the excavation assembly 2 before laying, and can control the angles of the rocker arm 5 and the bucket 7 by the first motor 6 and the second motor 8, so that the excavation depth of the bucket 7 meets the engineering technical requirements. The assembly avoids the problem of equipment power consumption caused by the additional use of an excavator; through the integrated laying assembly, after the foundation pit is excavated at the front end, the double-headed motor 12 will control the roller 13 to rotate and convey the cable 14 to the casing 16, and the cable 14 will follow the casing 16 to enter the bushing 19 and the protective cover 17, thereby achieving the point-to-point laying effect of the cable 14. This component avoids the problem of reduced positioning accuracy caused by subsequent traction and laying; through the provision of the foundation pit moving component 3, the driving components of the device - the transmission wheel 21 and the crawler 22 are set on both sides of the foundation pit. This design can not only prevent the entire device from sinking into the interior of the foundation pit, but also achieve the auxiliary positioning effect of the foundation pit excavation position through the crawler 22 on both sides, ensuring that the excavated foundation pit is always along the direction of the equipment's running track; through the provision of the excavation and laying integrated structure, the equipment simultaneously achieves the technical effects of excavation, positioning and point-to-point laying, achieves the efficiency of one machine for multiple uses, and avoids the problem of energy waste caused by repeated use of excavators and traction equipment; through the provision of the synchronous gathering type pre-buried component 4, the component synchronously utilizes the rotation effect of the double-headed motor 12 on the roller 13 transmission cable 14, and transmits the rotation torque to the surface of the auger rod through the belt 28 transmission method. The auger 26 on the surface of the auger rod is a gathering structure with a large outer circle and a small inner circle, which can continuously transport the mud and sand just excavated from the outside to the inside of the foundation pit, so that the equipment achieves the effect of digging and burying at the same time, and greatly improves the process efficiency. At the same time, timely burying the cable 14 can also avoid the damage problem that may be caused by the long-term external placement of the cable 14.
