Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 4 , the present utility model provides the following technical solutions: a soil backfilling corner ramming device, including a ramming device body, the ramming device body includes a locking frame 1, an independent adjustment mechanism 2 and a hydraulic pump 3, a bracket 6 is welded on the top of the locking frame 1, a top plate 5 is integrally formed on one side of the bracket 6, a hydraulic pump 3 is screwed to the bottom of the top plate 5, a plurality of independent adjustment mechanisms 2 are installed on the side of the locking frame 1, and the size specifications of each independent adjustment mechanism 2 are the same. A dispersion plate 9 is welded on the top of the locking frame 1, and the bottom of the dispersion plate 9 is pressed on the surface of each independent adjustment mechanism 2. This soil backfilling corner ramming device can be used at the corners of any angle.

[0024] When the present utility model is used, directly pull the handle 7 to move the whole device to the corner position. After starting the hydraulic pump 3 in the middle, the hydraulic pump 3 provides a downward impact force, and then the downward pressure can be applied by means of the bottom locking frame 1 and the independent adjustment mechanism 2 part to achieve the purpose of ramming the soil backfilled at the bottom. For the corner positions of different angles, before the ramming operation, by manually adjusting the rotating arm 13 on the locking frame 1, each independent adjustment mechanism 2 can be controlled to translate, and finally a parallelogram structure is formed between the plurality of independent adjustment mechanisms 2, and the angle at the overall corner is controlled to be the same as the angle of the ramming operation area for adaptation and use.

[0025] In this embodiment, the locking frame 1 includes a locking plate 8, a dispersion plate 9, a guide rod 10 and a rotating arm 13. A clamping plate 11 is integrally formed at the end of the guide rod 10. A linkage groove 14 is formed inside the rotating arm 13. A pull rod 15 is welded to the end of the rotating arm 13. A fixing column 12 is welded to one end of the surface of the locking plate 8. A shaft hole 16 is formed at one end of the rotating arm 13. The rotating arm 13 is sleeved on the surface of the fixing column 12 through the shaft hole 16. There are two dispersion plates 9 and guide rods 10 respectively. The bottom of the bracket 6 is welded to the surface of the locking plate 8 as a whole. The whole rotating arm 13 rotates around the fixing column 12, and the bottom of the rotating arm 13 is attached to the surface of the locking plate 8. By means of the transmission plate 4 at the top cooperating with the dispersion plate 9, the impact force provided by the top hydraulic pump 3 can be evenly diffused into each independent adjusting mechanism 2, ensuring that the impact force during the ramming process can act evenly on the covered area after adjustment at the bottom, and the ramming is more uniform and flat.

[0026] Specifically, by controlling the rotating arm 13 at the edge, it can rotate around the fixing column 12, and through the linkage groove 14 inside the rotating arm 13, the movable columns 18 on each adjusting plate 17 are driven to move simultaneously, controlling the movement of each adjusting plate 17, and the moving distances between each adjusting plate 17 will also vary due to the rotation effect of the rotating arm 13. Through this difference, a stepped state of multiple adjusting plates 17 can be controlled. As shown in the appendix Figure 1 At this time, the whole adjusting plate 17 can form an acute angle and an obtuse angle structure. By controlling the rotation of the rotating arm 13 through the above process until the angle formed between multiple adjusting plates 17 is the same as the angle of the corner to be rammed and constructed.

[0027] The position of each independent adjustment can be directly adjusted by rotating the pull rod 15, and during this adjustment process, it can be ensured that each independent adjusting mechanism 2 always remains in a fitting state, so the stability is higher and the adjustment process is simple and convenient. Specifically, each adjusting plate 17 during the adjustment process is affected by the extrusion of the clamping plate 11 at the outermost edge, ensuring that each adjusting plate 17 always remains in a fitting state.

[0028] In this embodiment, a handle 7 is inserted inside the top of the bracket 6, a transmission plate 4 is installed at the bottom of the hydraulic pump 3, the bottom of the transmission plate 4 is integrally fixed to the surface of the dispersion plate 9, the rear end of the bracket 6 is flush with the side of the locking plate 8, the transmission plate 4 is integrally circular in structure, and there is a gap between the bottom of the transmission plate 4 and each independent adjustment mechanism 2. The independent adjustment mechanism 2 includes an adjustment plate 17 and a movable column 18. The movable column 18 is welded to one end of the surface of the adjustment plate 17. A strip-shaped hole 19 is formed in the side of the adjustment plate 17. Impact plates 20 are arranged at the bottoms of both the adjustment plate 17 and the locking plate 8. The guide rod 10 passes through the inside of the strip-shaped hole 19. Each adjacent adjustment plate 17 is in contact and fit with each other. The inner side of the clamping plate 11 abuts against the side of the outermost adjustment plate 17. The movable column 18 passes through the linkage groove 14 inside the rotating arm 13. By splicing a plurality of independent adjustment mechanisms 2 with each other and through a single locking frame 1, a plurality of independent adjustment mechanisms 2 can be integrated with each other. Subsequently, by changing the relative positions of each independent adjustment mechanism 2, the angles at the corners of the entire independent adjustment mechanism 2 can be adjusted. After matching with the corners of the earthwork backfill to be processed, it can be used for ramming, with high flexibility.

[0029] Specifically, after translating each adjustment plate 17 through the above process and adjusting it to a preset angle at the corner, the hydraulic pump 3 is started at this time. The hydraulic pump 3 provides a downward impact force, which acts on the dispersion plate 9 along the transmission plate 4 and finally acts on each adjustment plate 17, so as to achieve the purpose of ramming the soil at the bottom.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.

This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
