Although the crushing equipment in the prior art can achieve the crushing of the backfill, in actual construction, when the width of the backfilled road surface is relatively large, the crushing equipment can only convey the crushed backfill for a short distance. Often, the backfill will accumulate at the edge of the area to be backfilled, and it is necessary to manually transfer the backfill to the remaining positions of the area to be backfilled, which is time-consuming and laborious.

[0003] For example, a Chinese patent discloses a backfill crushing device for road construction [Application No.: 202020833969.8], which includes a mud scraping device and a discharge hopper. A base is installed below the left end of the mud scraping device. A first installation end face is arranged above the base. A second installation end face is arranged below the crushing device.

Detailed Embodiment

[0023] As Figure 1 and Figure 2 shown, a backfill material crushing device for road construction includes a crusher 1. A crushing chamber 2 is arranged inside the crusher 1. A crushing mechanism 3 is arranged on the upper side of the crushing chamber 2. A vertical discharge port 4 is arranged at the bottom of the crushing chamber 2. A telescopic backfill material conveying mechanism 5 is arranged below the vertical discharge port 4. A horizontal discharge port 6 is also arranged on the side of the crusher 1. The telescopic backfill material conveying mechanism 5 horizontally extends outwards from the horizontal discharge port 6. Side baffles 7 are arranged on both sides of the horizontal discharge port 6.

[0024] In the present utility model, the crushing mechanism 3 above the crushing chamber 2 can crush the backfill material. The crushed backfill material can fall onto the telescopic backfill material conveying mechanism 5 through the vertical discharge port, and then the crushed backfill material is output from the horizontal discharge port to the area to be backfilled through the telescopic backfill material conveying mechanism 5. When outputting the backfill material to the area to be backfilled, the telescopic backfill material conveying mechanism 5 can extend and retract, so as to output the backfill material from near to far to different positions in the area to be backfilled, which can effectively reduce the workload of manual shoveling and transportation.

[0025] Specifically, the telescopic backfill material conveying mechanism 5 includes a driving wheel 8, a telescopic support plate assembly 9, a tensioning wheel assembly 10, and a conveyor belt 11 wound around the driving wheel 8, the telescopic support plate assembly 9, and the tensioning wheel assembly 10. The driving wheel 8 is arranged inside the telescopic support plate assembly 9, and the tensioning wheel assembly 10 is arranged below the telescopic support plate assembly 9. The driving wheel 8 can provide the rotating power for the conveyor belt 11 wound around the driving wheel 8, the telescopic support plate assembly 9, and the tensioning wheel assembly 10, so as to output the backfill material from the horizontal discharge port through the conveyor belt. The telescopic support plate assembly 9 can extend and retract, so as to adjust the distance between the backfill material output position and the crusher, so as to realize the backfill material conveying to different positions in the area to be backfilled. The tensioning wheel assembly 10 can cooperate with the telescopic support plate assembly 9 to make the conveyor belt always maintain the same tension degree.

[0026] Specifically, the telescopic support plate assembly 9 includes a fixed plate 12, a movable plate 13, and a translation driving assembly capable of driving the movable plate 13 to extend and retract along the length direction of the fixed plate 12. The translation driving assembly includes a first rotary driver 14. The end of the output shaft of the first rotary driver 14 is fixedly connected with a first threaded rod 15, and the first threaded rod 15 is screwed with the movable plate 13. When the first rotary driver operates, it can drive the first threaded rod to rotate. When the first threaded rod rotates, it can drive the movable plate to move horizontally along the length direction of the fixed plate, so as to be able to adjust the position of the output end of the conveyor belt to be near or far.

[0027] Those skilled in the art should understand that the first rotary driver can be a rotary oil cylinder or a motor, etc.

[0028] Preferably, a limiting structure is arranged between the movable plate 13 and the fixed plate 12. The limiting structure includes a limiting chute 16 recessed inward at the bottom of the fixed plate 12. A limiting slider 17 protruding from the top of the movable plate 13 is inserted into the limiting chute 16. The cross sections of the limiting chute 16 and the limiting slider are in a T shape. The limiting chute 16 and the limiting slider with a T-shaped cross section enable the movable plate to be supported by the fixed plate, making the movable plate more stable. Secondly, it can also limit the movable plate when the movable plate moves.

[0029] Specifically, the tensioning wheel assembly 10 includes a tensioning wheel 18 and a lifting and adjusting assembly capable of driving the tensioning wheel 18 to move towards or away from the telescopic support plate assembly 9. By driving the tensioning wheel to approach or move away from the telescopic support plate assembly 9 through the lifting and adjusting assembly, the tension of the conveyor belt can be adjusted. When the telescopic support plate assembly 9 extends, the lifting and adjusting assembly drives the tensioning wheel to approach the telescopic support plate assembly 9. When the telescopic support plate assembly 9 shortens, the lifting and adjusting assembly drives the tensioning wheel to move away from the telescopic support plate assembly 9.

[0030] Specifically, the lifting and adjusting assembly includes two lifting sliders 19 driven by a lifting assembly. Both ends of the central axis of the tensioning wheel 18 are rotatably connected to the two lifting sliders 19. The lifting assembly includes a second rotary driver 20. A second threaded rod 21 perpendicular to the telescopic support plate assembly 9 is screwed onto the second rotary driver 20. The second threaded rod 21 is screwed to the lifting slider 19. When the second rotary driver operates, it can drive the second threaded rod to rotate. When the second threaded rod rotates, it can drive the lifting slider to move towards or away from the telescopic support plate assembly 9. When the lifting slider moves, it can drive the tensioning wheel 18 to move synchronously.

[0031] Those skilled in the art should understand that the second rotary driver can be a rotary oil cylinder or a motor, etc.

[0032] Specifically, the crushing mechanism 3 includes at least two crushing rollers 22 arranged in parallel.
