[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides a gravel cushion layer paving and compacting device for a steep slope, which solves the problems of low automation and relatively poor paving and compacting efficiency of existing gravel cushion layer paving and compacting devices for steep slopes. It is convenient to guide and move the machine body on the steep slope through a guide member, lay and fix the grid belt on the steep slope through a conveying trough, convey the gravel into a storage chamber through an input pipe, and then lay the gravel in the storage chamber into the laid grid belt. When the paving mechanism is running, the linkage compacting plate is lifted and lowered back and forth in the device trough, thereby compacting the gravel conveyed into the grid belt, thereby realizing automated gravel cushion layer paving and compacting operation.

[0017] 2. The present invention provides a device for paving and compacting a gravel cushion layer on a steep slope. During the movement of the machine body, the electromagnet will generate a magnetic push on the fixed hook to push the fixed hook into the guide rail. The friction resistance between the fixed hook and the inner wall of the guide rail is relatively large, so that the buffer spring pushes the fixed hook to pop out at a slower speed. After the mesh belt is guided to a position that fits the guide rails on both sides, the fixed hook slowly pops out and is plugged and suspended with the mesh belt. At the same time, the gravel in the storage chamber is evenly pushed into the connecting net through the compacting cylinder. The mesh belts are connected by the connecting net to hold the gravel. At the same time, the mesh belts on both sides are fixed by the fixed hook to maintain a relatively stable state. No manual paving is required. The compacting cylinder compacts the gravel between the mesh belt and the connecting net during rotation.

[0018] 3. The present invention provides a device for paving and compacting a gravel cushion layer on a steep slope. When the guide cylinder rotates clockwise, the fourth belt drives the compacting cylinder to rotate clockwise, so that the compacting cylinder can push the gravel in the storage chamber to the bottom of the machine body for compaction. The compacting cylinder drives the rotating shaft to rotate through the fifth belt, so that the first belt drives the cam to rotate. During the rotation, the cam intermittently pushes the sliding plate downward, the tension spring is stretched, and the shock-absorbing spring pushes the compacting plate to press down reciprocally, so that the gravel at the bottom can be compacted. At the same time, the buffering effect of the shock-absorbing spring ensures the compaction strength and does not cause excessive extrusion. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The driving member 17 includes a driving motor 26 fixedly installed in the body 1, and the model of the driving motor 26 is preferably YYHS-40. The output end of the driving motor 26 is coaxially fixedly connected with a driving disk 27, and the outer wall of the driving disk 27 is transmission-connected with a second belt 28 transmission-connected to the pulley on the rolling drum 15. A first gear 29 is rotationally connected in the side plate 41, and the first gear 29 is transmission-connected to a third belt 30 transmission-connected to the pulley on the rolling drum 15 through a pulley. The guide drum 16 is coaxially fixedly connected with a second gear 31 meshing with the first gear 29.

[0035] The cushioning mechanism 7 includes a compacting cylinder 32 rotatably connected to the side plates 41 on both sides, one end of the compacting cylinder 32 is connected to a fourth belt 33 connected to the pulley on the second gear 31 through a pulley transmission, and the compacting cylinder 32 is connected to a fifth belt 34 connected to the rotating shaft 24 through a pulley transmission.

[0036] The fixing member 18 includes a plurality of fixing hooks 35 installed on the side of the guide rail 13. The fixing hooks 35 are connected to the guide rail 13 in a sliding manner in the horizontal direction. One end of the fixing hook 35 is fixedly connected to a buffer spring 36 fixedly connected to the guide rail 13. The fixing hook 35 is made of a magnetic metal material. An electromagnet 37 for repelling and pushing the fixing hook 35 is fixedly connected to the body 1.

[0037] In this embodiment, before the gravel paving construction on the steep slope is carried out, the guide rails 13 are now evenly spaced on the steep slope and fixed obliquely on the steep slope surface by bolts and other fixing devices to ensure that the rollers 14 on both sides of the body 1 can move along the guide rails 13, and at the same time, the grid belt 2 can be fitted and fixed to both sides of the guide rails 13. Gravel is input into the input pipe 8 through the conveyor. The body 1 will drive the input pipe 8 to move during the movement of the guide rail 13. The input pipe 8 can use a hard casing to facilitate shaping and telescopic movement. The body 1 is placed on the upper end of the guide rail 13, and the grid belt 2 is passed through the conveying trough 6. After being guided and bent by the rolling cylinder 15 and the guide cylinder 16, it is fitted to the steep slope surface. The top two sides of the grid belt 2 are pre-suspended and fixed to the fixing hooks 35 on both sides to complete the preliminary installation process.

[0038] Thereafter, during the movement of the machine body 1, the electromagnet 37 will generate a magnetic push on the fixing hook 35, pushing the fixing hook 35 into the guide rail 13. The friction resistance between the fixing hook 35 and the inner wall of the guide rail 13 is relatively large, so that the buffer spring 36 pushes the fixing hook 35 to pop out at a relatively slow speed. After the mesh belt 2 is guided to a position that fits the guide rails 13 on both sides, the fixing hook 35 slowly pops out and is plugged and suspended with the mesh of the mesh belt 2. At the same time, the gravel in the storage chamber 9 is evenly pushed into the connecting net 3 through the compacting cylinder 32. The mesh belts 2 are connected by the connecting net 3 to hold the gravel. At the same time, the mesh belts 2 on both sides are fixed by the fixing hook 35 to maintain a relatively stable state. No manual paving is required. The compacting cylinder 32 compacts the gravel between the mesh belt 2 and the connecting net 3 during rotation.

[0039] When the guide cylinder 16 rotates clockwise, the fourth belt 33 will be driven to drive the compacting cylinder 32 to rotate clockwise, so that the compacting cylinder 32 can push the gravel in the storage chamber 9 to the bottom of the machine body 1 for compaction operation. The compacting cylinder 32 drives the rotating shaft 24 to rotate through the fifth belt 34, so that the first belt 25 drives the cam 23 to rotate. During the rotation, the cam 23 intermittently pushes the sliding plate 20 downward, the tension spring 19 is stretched, and the shock-absorbing spring 21 pushes the compacting plate 11 to press down reciprocatingly, so that the gravel at the bottom can be compacted. At the same time, the buffering effect of the shock-absorbing spring 21 ensures that the compaction strength will not be excessively squeezed.

[0040] The driving motor 26 drives the driving disk 27 to rotate, thereby driving the second belt 28 to make the rolling drum 15 rotate counterclockwise. During the counterclockwise rotation of the rolling drum 15 on the steep slope surface, the obstacles remaining on the steep slope will be pushed to the bottom of the steep slope through the surrounding slag discharge groove 40 to avoid affecting the laying of the grid belt 2. The rolling drum 15 drives the first gear 29 to rotate counterclockwise through the third belt 30, so that the second gear 31 drives the guide drum 16 to rotate clockwise. The driving force between the rolling drum 15 and the guide drum 16 can transport the grid belt 2 to the surface of the steep slope to complete the laying.

[0041] It is worth noting that: since the rolling drum 15 can roll on a steep slope surface, and the roller 14 is on the guide rail 13, the electric telescopic rod 38 is in a retracted state at this time. When the machine body 1 reaches the flat ground, the driving frame 39 can be pushed downward by the electric telescopic rod 38, so that the roller 14 lifts the machine body 1, and the rolling drum 15 is separated from the bottom surface. Thereafter, the machine body 1 can be driven to move by the roller 14.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
