[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5A slope gravel paving device includes a base 1 and a gravel storage box 5. The gravel storage box 5 contains gravel raw materials and has a discharge port at the bottom. The discharge port can be provided with an opening and closing component to realize the opening and closing of the discharge port, thereby realizing the falling of the gravel raw materials and the suspension of falling.

[0023] A movable groove 6 is provided on the upper end surface of the base 1, in which a horizontal screw 7 is rotatably provided, a nut 10 is threadedly sleeved on the horizontal screw 7, a vertical frame 2 is provided on the nut 10 through an insertion mechanism, a vertical screw 3 is rotatably provided on the vertical frame 2, the vertical screw 3 is connected to the base 1 through a transmission mechanism, and a lifting block 4 connected to the gravel storage box 5 is threadedly sleeved on the vertical screw 3.

[0024] The plug-in mechanism includes an insert block 13 mounted on the outer wall of the nut 10, the insert block 13 is arranged vertically upward, an arc groove is arranged on the surface of the vertical frame 2 contacting the nut 10, and a slot corresponding to the insert block 13 is arranged on the inner wall of the arc groove. Figure 5 As shown, when the insert block 13 is in the slot and the nut 10 moves on the horizontal screw rod 7, the vertical frame 2 can be synchronously moved.

[0025] The above-mentioned movable connection method can directly lift up the vertical frame 2 to disengage it from the nut 10. It can be conveniently lifted up and disengaged only when the gravel storage box 5 is empty. In the fully loaded state, the downward pressure ensures that the vertical frame 2 will not be displaced and disengaged from components such as the nut 10. Components such as the base 1 can be installed with counterweight blocks to prevent the gravel storage box 5 from being too heavy and causing the device to tilt.

[0026] The transmission mechanism includes a rack 9 mounted on the upper end surface of the base 1, a transmission shaft connected to the vertical screw 3 is mounted on the vertical frame 2, and a gear 11 is provided at the end of the transmission shaft, and the gear 11 is meshed with the rack 9. Figure 3 As shown, when the gear 11 moves with the vertical frame 2 and other components, it can rotate under the intervention of the rack 9, thereby driving the vertical screw 3 in the vertical frame 2 to rotate synchronously.

[0027] A limit block 12 is provided on the outer wall of the nut 10, and the limit block 12 is arranged vertically downward. A limit groove corresponding to the limit block 12 is provided on the inner bottom wall of the movable groove 6. When the limit block 12 is in the limit groove, it can limit the nut 10, thereby preventing it from rotating with the vertical screw 3.

[0028] A limit rod 14 is provided in the vertical frame 2. The limit rod 14 is vertically arranged and parallel to the vertical screw 3. The limit rod 14 slides through the lifting block 4. The function of the limit rod 14 is also to limit the lifting block 4, which realizes the limitation of the lifting block 4, thereby preventing it from rotating with the vertical screw 3.

[0029] A driving motor 8 is installed on one end of the base 1. The output shaft of the driving motor 8 rotates and passes through the outer wall of the base 1 and extends into the movable groove 6. The end of the output shaft of the driving motor 8 is fixedly connected to the end of the horizontal screw 7. The driving motor 8 is a power device and is arranged outside, which has the advantages of good heat dissipation and convenient maintenance.

[0030] When the utility model is used, Figure 1 In this state, the base 1 is on the side of the slope, the gravel storage box 5 is on the upper end surface of the slope, and the initial position is at a low position. At this time, the driving motor 8 is started to drive the horizontal screw 7 to rotate. At the same time, the opening and closing assembly in the discharge port of the gravel storage box 5 is opened to make the gravel raw material fall. The gravel raw material can fall on the slope surface. When the horizontal screw 7 rotates, the nut 10 threadedly mounted thereon can drive the vertical frame 2 to move. During the movement of the vertical frame 2, the gear 11 moves relative to the rack 9 and therefore rotates. The rotation of the gear 11 can drive the vertical screw 3 to rotate synchronously. When the vertical screw 3 rotates, the nut 10 threadedly sleeved thereon will cooperate with the lifting block 4 to drive the gravel storage box 5 to rise. Therefore, the gravel storage box 5 can move obliquely to complete the gravel paving operation on the slope surface.

[0031] In this solution, the vertical frame 2 can be directly lifted up to disengage it from the nut 10, and the plug block 13 can be disengaged from the slot, thereby realizing convenient disassembly of components such as the gravel storage box 5 relative to the base 1, so that the device can be quickly stored when not in use, and the overall weight of the device can be dispersed to facilitate operations such as transportation.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
