Description

Technical Field

[0001] The utility model relates to the technical field of soil backfilling, in particular to a soil backfilling device. Background Art

[0002] After trenching and sampling the soil or pre-burying electrical wires, the soil needs to be backfilled into the trench to complete the repair of the ground soil. However, most of the existing soil backfilling is done manually.

[0003] Usually, people directly put the soil into the gully through tools such as shovels and spades, and then use the shovel surface to knock and compact it. However, this backfilling consumes a lot of physical strength of people. For this reason, we propose a soil backfilling device to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art involved in the background technology and proposes a soil backfilling device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The shovel board can be made to fit with the ground, and then people push the installation plate to drive the connecting plate and the shovel board to move, so that the shovel board and the connecting plate push the soil to the inside of the gully, and then the connecting plate and the shovel board rise, so that the shovel board descends to compact the soil, which is more labor-saving to use.

[0008] Preferably, a supporting shaft is provided inside the sliding slot, and the connecting rod is sleeved on the outside of the supporting shaft;

[0009] The sliding stability of the connecting rod can be improved, and then the sliding stability of the connecting plate and the scraper plate driven by the connecting rod can be improved.

[0010] Preferably, a mounting bracket is provided at the middle position of the top end of the mounting plate, a servo motor is provided at the top end of the mounting bracket, a transmission screw is provided at the output end of the servo motor, and the tail end of the connecting rod is sleeved on the outside of the transmission screw and is threadedly connected with the transmission screw;

[0011] The servo motor can be used to drive the transmission screw to rotate, so that the transmission screw drives the connecting rod to move through the threaded structure, so that the connecting rod drives the lifting of the connecting plate and the shovel board more conveniently, thereby making it easier for the shovel board to compact the soil.

[0012] Preferably, a support plate is provided at the end of the connecting rod, the connecting rod and the support plate form a T-shaped arrangement, and the side walls of the support plate and the connecting plate are in contact with each other;

[0013] The contact area between the connecting rod and the connecting plate can be made wider, so that the stability of the connecting plate is better and the connection plate and the shovel plate are prevented from swinging left and right.

[0014] Preferably, both ends of the support plate are provided with connecting blocks, both sides of the connecting plate are provided with limiting grooves, and the connecting blocks extend to the inside of the limiting grooves;

[0015] The connecting plate can drive the shovel plate and the support plate to have a certain movable space, so that the vibration generated by the shovel plate when compacting the soil will not be transmitted to the top of the connecting rod, so that the transmission between the connecting rod and the transmission screw will not be affected.

[0016] Preferably, a fixed shaft rod is arranged inside the limiting groove, and the connecting block is sleeved on the outside of the fixed shaft rod;

[0017] The connection block can be made to slide more stably in the limiting groove, thereby preventing the connection block from being separated from the limiting groove.

[0018] Preferably, a buffer spring is sleeved on the outside of the fixed shaft, one end of the buffer spring is fixedly connected to the connecting block, and the other end of the buffer spring is fixedly connected to the inner wall of the limiting slot;

[0019] The buffer spring can support the connecting block, so that when the connecting plate vibrates, the connecting plate can be buffered by the buffer spring, further preventing the vibration from being transmitted to the top of the connecting rod.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. According to the utility model, the personnel can push the installation plate to drive the connecting plate and the shoveling plate to move, so that the connecting plate and the shoveling plate drive the soil on both sides of the gully to be backfilled into the gully, and then the connecting plate and the shoveling plate rise, and then the shoveling plate drops sharply to complete the compaction of the soil above the gully, thereby making the backfilling and repair of the soil more convenient, saving manpower, and improving work efficiency.

[0022] 2. When the earth-shoveling plate of the utility model is lowered to complete compaction, the vibration force generated can be buffered by the buffer spring, so that the vibration of the connecting plate will not be transmitted to the top of the connecting rod, and the transmission between the driving screw and the connecting rod will not be affected, which is convenient to use.

[0030] For a detailed description of the support plate 12 and the connecting block 13 in this embodiment, please refer to Figure 3 and Figure 4 A support plate 12 is provided at the end of the connecting rod 6, so that the connecting rod 6 and the support plate 12 form a T-shaped arrangement, and the support plate 12 is fitted with the side wall of the connecting plate 3, and connecting blocks 13 are provided at both ends of the support plate 12, and then limiting grooves 14 are provided on both sides of the connecting plate 3, so that the connecting block 13 extends to the inside of the limiting groove 14, and a fixed shaft rod 15 is provided inside the limiting groove 14, and the connecting block 13 is sleeved on the outside of the fixed shaft rod 15, so that a buffer spring 16 is sleeved on the outside of the fixed shaft rod 15, and then one end of the buffer spring 16 is fixedly connected to the connecting block 13, and the other end of the buffer spring 16 is fixedly connected to the inner wall of the limiting groove 14.

[0031] Working principle: When the utility model is in use, a person directly pushes the mounting plate 1 so that the shovel plate 4 fits against the ground, so that the soil can be driven to backfill into the gully during the movement of the mounting plate 1. Then, the servo motor 10 drives the transmission screw 11 to rotate, and the transmission screw 11 drives the connecting rod 6 to rise. The connecting rod 6 drives the connecting plate 3 and the shovel plate 4 to rise through the support plate 12. Then, the servo motor 10 rotates in the opposite direction to drive the shovel plate 4 to descend, so that the shovel plate 4 completes the compaction of the soil.

[0032] When the shovel plate 4 is compacted, it will vibrate when it contacts the soil for a moment, and the vibration can be buffered by the buffer spring 16, so that the stability of the connecting rod 6 itself is better, thereby avoiding the situation where the vibration of the connecting rod 6 causes damage to the driving screw 11.
