Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0030] As shown in Figures 1-6 The present application provides a soil construction backfilling device, which comprises a hopper 1, a tamping mechanism 4 and an opening and closing mechanism 6. The hopper 1 is provided with a plurality of wheels 2 at the bottom, and a pair of handrails 3 is installed on one side of the hopper 1. The handrails 3 can be fixed to the outer side wall of the hopper 1 by welding. The bottom of the hopper 1 is provided with an opening. The tamping mechanism 4 comprises a tamping plate 41, which is located on one side of the hopper 1. The opening and closing mechanism 6 is located at the opening of the bottom of the hopper 1. The hopper 1 is further provided with a driving mechanism 5 for driving the tamping plate 41 to move vertically and reciprocally. The wheels 2 are synchronously driven to move vertically and reciprocally during rotation.

[0031] In the present embodiment, the present application is a device for completing soil backfilling operation. Specifically, the soil is poured into the hopper 1 in advance. The operator can hold the handrails 3 to control the movement of the wheels 2 to move to the place where backfilling is needed. At this time, the opening of the bottom of the hopper 1 is opened by the opening and closing mechanism 6, and the device is controlled to move. At this time, the soil in the hopper 1 is discharged to perform backfilling operation. However, the tamping mechanism 4 can be synchronously driven to move vertically and reciprocally by the driving mechanism 5 during the movement of the wheels 2. The tamping plate 41 is used to tamp the ground to improve the compactness of the backfilled soil layer. No additional tamping operation is needed after backfilling, which simplifies the operation steps and improves the construction efficiency.

[0032] As shown in Figure 2 The opening and closing mechanism 6 comprises a shielding plate 61 and a power source for driving the shielding plate 61 to move. The shielding plate 61 covers the opening of the bottom of the hopper 1.

[0033] In the present embodiment, the shielding plate 61 is controlled to move by the power source, so as to cover the opening of the bottom of the hopper 1, thereby making the opening of the bottom of the hopper 1 in a closed state. When the power source controls the shielding plate 61 to move away from the opening of the bottom of the hopper 1, the opening of the bottom of the hopper 1 is in an open state.

[0034] As shown in Figure 6As shown, the power source comprises a mounting plate 62 and a cylinder 63, the mounting plate 62 is mounted to the bottom of the hopper 1, the mounting plate 62 can be fixed to the bottom of the hopper 1 by bolts, the cylinder 63 is mounted to one side of the mounting plate 62, the cylinder 63 is also fixed to one side of the mounting plate 62 by bolts, and the output end of the cylinder 63 is keyed connected with the shielding plate 61.

[0035] In this embodiment, by stretching or shrinking with the cylinder 63, the shielding plate 61 is driven to move horizontally, so as to realize the closing and opening of the opening at the bottom of the hopper 1.

[0036] As shown in the figure, Figure 3 The driving mechanism 5 comprises a pair of fixed blocks 51 and a belt 54, one side of one of the fixed blocks 51 is rotatably connected with a first pulley 52, one side of one of the wheels 2 is mounted with a second pulley 53, the second pulley 53 is fixed to one side of the wheel 2 by bolts, the second pulley 53 is drivingly connected with the first pulley 52 through the belt 54, one side of the other fixed block 51 is rotatably connected with a turntable 56, the first pulley 52 is connected with the turntable 56 through a clutch, the driving mechanism 5 further comprises a connecting rod 55, an eccentric pin shaft 58 is mounted on the outer side wall of the other turntable 56 and away from the center position, the connecting rod 55 is fixedly connected with the tamping plate 41 at the bottom end, and a rectangular frame 57 is mounted at the top end of the connecting rod 55, the eccentric pin shaft 58 penetrates through the rectangular frame 57.

[0037] In this embodiment, when the device moves, the wheels 2 rotate synchronously, under the transmission of the belt 54, the first pulley 52 can be driven to rotate, under the connection of the clutch, the turntable 56 can be controlled to rotate synchronously, by the cooperation of the rectangular frame 57 and the eccentric pin shaft 58, the connecting rod 55 and the tamping plate 41 at the bottom can be driven to move vertically and reciprocally, so as to realize the synchronous driving of the tamping plate 41 to move vertically and reciprocally during the movement of the device, and then the tamping plate 41 is used to tamp the backfilled soil layer.

[0038] As shown in the figure, Figure 4 The clutch comprises a spline sleeve 59, an electric push rod 510 and a spline shaft 511, the spline sleeve 59 is coaxially fixedly connected with the turntable 56, the electric push rod 510 is coaxially fixedly connected with the first pulley 52, the spline shaft 511 is mounted to the end of the electric push rod 510, and the spline sleeve 59 matches with the spline shaft 511.

[0039] In the embodiment, when the spline shaft 511 is inserted into the spline sleeve 59, the spline sleeve 59 and the spline shaft 511 are in a connected state, that is, the first pulley 52 can rotate synchronously with the rotating disc 56, thereby realizing synchronous driving of the vertical reciprocating movement of the ramming plate 41 during the movement of the device. When the backfilling operation is completed and the device is moved, the electric push rod 510 can be controlled to retract, so that the spline shaft 511 is separated from the spline sleeve 59. At this time, the spline sleeve 59 and the spline shaft 511 are in a separated state, that is, the first pulley 52 cannot rotate synchronously with the rotating disc 56, thereby facilitating the movement of the device, stopping the operation of the ramming mechanism 4 and the driving mechanism 5 after the backfilling operation, and reducing the degree of wear.

[0040] As shown in Figure 5 The ramming plate 41 is provided with a pair of connecting blocks 42 on the outer side wall. A threaded rod 43 is threadedly connected to each of the connecting blocks 42. A roller 44 is mounted at the bottom end of the threaded rod 43.

[0041] In the embodiment, when the backfilling operation is completed and the device is moved, the roller 44 can be controlled to move downward by rotating the threaded rod 43, so that the roller 44 abuts against the ground, thereby further facilitating the transportation of the device.

[0042] Working principle:

[0043] By pouring the soil into the hopper 1 in advance, the operator can hold the handrail 3 and control the wheels 2 to move, so that the device moves to the place where backfilling is needed. At this time, the bottom opening of the hopper 1 can be opened by using the opening and closing mechanism 6, and the device can be controlled to move. At this time, the soil in the hopper 1 is discharged and backfilling is performed. During the movement of the device, the wheels 2 rotate synchronously. Under the transmission action of the belt 54, the first pulley 52 can be driven to rotate. Under the connection of the clutch, the rotating disc 56 can be controlled to rotate synchronously. By the cooperation of the rectangular frame 57 and the eccentric pin shaft 58, the connecting rod 55 and the bottom ramming plate 41 can be driven to perform vertical reciprocating movement, thereby realizing synchronous driving of the vertical reciprocating movement of the ramming plate 41 during the movement of the device. In turn, the ramming plate 41 can be used to tamp the backfilled soil layer, thereby improving the compactness of the backfilled soil layer

[0044] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
