The left and right sides of the descending plate 3 are hinged with side plates 15 near the front end, a through hole is provided at the center of the upper side of the top plate 10, the threaded column 4 is rotatably connected to the through hole of the top plate 10 near the bottom end thereof, the lower side of the top plate 10 is welded with a column 9, and the bottom end of the column 9 is welded with a bottom plate 8; the left and right sides of the support plate 21 are welded with side plates 15, a drive motor 17 is installed on the right side of the side plate 15 on the right side, and an active The driving drum 25 has a transmission belt 16 embedded in its outer side surface, a driven drum 26 embedded in its inner side surface of the transmission belt 16, the left and right ends of the driven drum 26 are rotatably connected to the side plate 15, a bracket 22 is welded to the upper side surface of the support plate 21, the bracket 22 is provided with a through hole extending through the left and right sides, a support rod 24 is welded to the inner side of the through hole of the bracket 22, and a supporting wheel 19 and a side wheel 20 are rotatably connected to the outer side surface of the support rod 24; the left and right ends of the driving drum 25 are rotatably connected to the side plate 15.

[0024] When the utility model is carrying out the transportation of crushed stone and soil, the threaded column 4 is driven to rotate by the lifting motor 14. Since the threaded surface on the outer side of the threaded column 4 is meshed and connected in the threaded through hole of the lifting plate 3, the lifting plate 3 moves upward or downward along the support frame 2. At this time, the hydraulic workstation 23 supplies oil to the two groups of hydraulic rods 5 through the oil pipe. The hydraulic rods 5 cooperate with the lifting plate 3 to make the side plate 15 carry the conveyor belt 16 to penetrate into the basement pit according to the depth of the basement pit, and adjust the soil landing height and front and rear positions of the conveyor belt 16 in the basement pit. After the position is determined, the driving motor 17 drives the active drum 25 to rotate, and the active drum 25 drives the conveyor belt 16 between the active drum 25 and the driven drum 26. The outer side surface moves in translation, and the external excavator shovels the gravel and soil into the feed hopper 1, and the gravel and soil falls onto the conveyor belt 16 from the opening at the bottom of the feed hopper 1, and then the side wheels 20 inclined at an angle of 15 degrees cooperate with the supporting wheel 19 to form a concave structure of the conveyor belt 16, so that the gravel and soil are scooped in the middle of the conveyor belt 16 to prevent the gravel and soil from sliding out from both sides of the conveyor belt 16. The gravel and soil are transported into the basement earth pit by the conveyor belt 16, avoiding the external excavator from approaching the building for backfilling work. When a part of the earth pit is backfilled, the rope is tied to the pull ring 12, and the external vehicle uses the rope to pull the gravel and soil backfilling conveying device to move along the edge of the earth pit to the next part relying on the four sets of traveling wheels 6, and backfilling work is carried out again.

[0025] In the disclosed embodiment, two groups of ear plates are symmetrically provided on the left and right sides of the lifting plate 3, each group of ear plates is provided with a through groove structure penetrating from top to bottom, the support frame 2 is inserted into the ear plate through hole of the lifting plate 3, and a threaded through hole is provided on the upper side of the lifting plate 3. The outer side surface of the threaded column 4 is threadedly engaged with the threaded through hole of the lifting plate 3, and the lifting plate 3 is driven by the threaded column 4 to move vertically upward or downward along the support frame 2, thereby changing the height position of the conveyor belt 16 to adapt to the transportation and backfilling of gravel in basements of different depths.

[0026] In the disclosed embodiment, there are two groups of hydraulic rods 5, which are symmetrically distributed on the left and right sides of the conveyor belt 16. The bottom ends of the hydraulic rods 5 are hinged to the front end of the bottom plate 8, and the top ends of the two groups of hydraulic rods 5 are respectively hinged to the two groups of side plates 15, so that the hydraulic rods 5 form a connecting rod motion mechanism between the bottom plate 8 and the side plates 15. The hydraulic rods 5 drive the side plates 15 to complete the transmission of the conveyor belt 16 conveying inclination angle, thereby completing the front and rear adjustment of the gravel falling position.

[0027] In the disclosed embodiment, the outer side surfaces of the support rod 24 near the left and right ends are both 15-degree bent structures, and the two sets of side wheels 20 are respectively rotatably connected to the 15-degree bent structures of the support rod 24, so that the side wheels 20 are tilted at an angle of 15 degrees. The outer side surface at the center position of the support rod 24 is rotatably connected to the supporting rotating wheel 19. The side wheels 20 tilted at an angle of 15 degrees cooperate with the supporting rotating wheel 19 to form an inner concave structure of the conveyor belt 16, thereby preventing gravel and soil from slipping out from both sides of the conveyor belt 16 during transportation on the conveyor belt 16.

[0028] In the disclosed embodiment, the feed hopper 1 is a cylindrical structure that penetrates from top to bottom. The top opening of the feed hopper 1 is larger than the bottom opening of the cylinder. The bottom opening of the feed hopper 1 is opposite to the conveyor belt 16 in vertical direction, so that the gravel and soil can fall accurately onto the conveyor belt 16.

[0029] In the disclosed embodiment, the weight basket 13 is connected to the upper side of the top plate 10 near the rear end by bolts, and two sets of weights 11 are inserted into the inner side of the weight basket 13 to prevent the crushed stone and soil backfill conveying device from tilting forward and falling into the pit due to the excessive weight of the crushed stone and soil being conveyed.

[0030] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The hydraulic rod 5, lifting motor 14, drive motor 17 and hydraulic workstation 23 used above are all common components on the market. When you buy them back and use them, you only need to connect them according to the instruction manual purchased together, so I will not repeat them here.

[0031] The technical solution of the present invention is not limited to the scope of the embodiments of the present invention, and the technical contents not described in detail in the present invention are all well-known technologies.
