Specific embodiments

[0021] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0022] Embodiment 1: As Figures 1-3 , it includes a base 100. A conveyor belt 110 is fixedly installed on the outer wall of the top of the base 100. A crushing bin is fixedly installed on the outer wall of the top of the base 100. The crushing bin includes a lower bin body 200 and an upper bin body 220 installed on the top of the lower bin body 200. Semi-circular grooves are formed on the inner walls of both the lower bin body 200 and the upper bin body 220. The crushing roller is rotatably connected between the upper and lower semi-circular grooves through bearings. There are two crushing rollers symmetrically distributed on the left and right. The crushing roller includes a roller shaft 300 and a detachably and fixedly installed shredding roller 320. Shredding edges 330 are detachably installed on the outer wall of the shredding roller 320. A number of shredding edges 330 are evenly distributed. The two crushing rollers are connected by gear meshing transmission. The crushing roller is used for crushing the road backfill material.

[0023] The specific use scenario of this embodiment is: by setting the structure between the lower bin body 200 and the upper bin body 220 as a split structure, the crushing roller can be flexibly installed. At the same time, by setting the crushing roller as a split structure, the structures such as the shredding roller 320 and the shredding edges 330 in the crushing roller that are prone to wear can be replaced separately after wear, which is convenient for improving the economy of equipment use and facilitating the later maintenance of the equipment.

[0024] Embodiment 2: As Figure 3, a C-shaped support frame 120 is fixedly installed at the top of the base 100. The C-shaped support frames 120 are located on the left and right sides of the conveyor belt 110. The two C-shaped support frames 120 cooperate to fixedly install the lower bin 200. The C-shaped support frames 120 play a role in supporting the outer wall of the lower bin 200. A servo motor 230 is fixedly installed on the outer wall of the top of the C-shaped support frame 120. The output shaft of the servo motor 230 is in transmission connection with the outer wall of the roller shaft 300 through a pulley 231 and a belt. The inner wall of the lower bin 200 is arranged in a trapezoidal structure. A discharge hole 210 is opened on the inner wall of the bottom of the lower bin 200. The discharge hole 210 is located above the conveyor belt 110. An open mouth 221 is provided at the top of the lower bin 200.

[0025] The specific usage scenario of this embodiment is as follows: By setting the inner wall of the lower bin 200 in a trapezoidal structure, it is easy for the crushed road backfill material to quickly gather at the discharge hole 210 for discharging. Under the action of driving the servo motor 230 to rotate, the two crushing rollers move towards each other, thereby squeezing the road backfill material, so that the road backfill material between the two crushing rollers can be squeezed and crushed. At the same time, under the action of installing the crushing edges 330 on the surface of the crushing rollers, the friction between the two crushing rollers 320 is increased, and it is convenient to crush and convey the road backfill material between the two crushing rollers 320 for extrusion.

[0026] Embodiment 3: As Figures 3-5 , the crushing roller includes a hollow frame 310. The hollow frame 310 is fixedly installed on the outer wall of the roller shaft 300. The outer wall of the hollow frame 310 is fitted and inserted with a crushing roller 320. The outer wall of the crushing roller 320 is evenly provided with card slots 321. The inner wall of the card slots 321 is evenly provided with insertion holes 322. The bottom outer wall of the crushing edge 330 is evenly fixedly connected with protruding blocks 332. The outer wall of the protruding blocks 332 is in fitting and insertion connection with the inner wall of the insertion holes 322. The outer wall of the crushing edge 330 is set in a U shape. Insertion plates 331 are provided at both ends of the crushing edge 330. Positioning rings 340 are inserted and installed on the outer walls of the left and right ends of the crushing roller 320. The positioning rings 340 are used to fix the cooperation between the crushing edges 330 and the outer wall of the crushing edges 330.

[0027] The specific usage scenario of this embodiment is as follows: After the surface of the crushing edge 330 is frictionally damaged, by removing the upper bin 220 at the top of the lower bin 200, taking out the crushing roller from the semi-circular groove, then removing the two positioning rings 340, and removing the damaged crushing edge 330 for replacement.

[0028] The working principle of the present utility model is as follows: When in use, those skilled in the art turn on the servo motor 230, causing the servo motor 230 to drive one of the roller shafts 300 to rotate. Since the two roller shafts 300 are connected by gear meshing transmission, the two roller shafts 300 rotate towards each other under the drive of the servo motor 230. By putting the roadbed backfill material to be crushed into the opening 221 at the top of the upper bin body 220, under the action of gravity, the roadbed backfill material falls between the two crushing rollers. Under the action of driving the servo motor 230 to rotate, the two crushing rollers move towards each other, thereby squeezing the roadbed backfill material, enabling the roadbed backfill material between the two crushing rollers to be squeezed and crushed. At the same time, with the broken material edges 330 installed on the surface of the crushing rollers, the friction between the two broken material rollers 320 is increased, and it is convenient to crush and convey the roadbed backfill material between the two broken material rollers 320 for extrusion. The crushed roadbed backfill material falls onto the surface of the conveyor belt 110 through the discharge hole 210, and the roadbed backfill material is discharged through the conveyor belt 110 to avoid accumulation at the bottom of the lower bin body 200. After the broken material edges 330 on the surface are damaged by friction, the upper bin body 220 at the top of the lower bin body 200 is disassembled, the crushing roller is taken out from the semi-circular groove, then the two positioning rings 340 are removed, the damaged broken material edges 330 are removed and replaced, and then the crushing roller and the upper bin body 220 are reinstalled.

[0029] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
