A plurality of nozzles are provided on the U-shaped tube 10, and the plurality of nozzles are all located inside the cover body 4;
[0027] The two first electric push rods 2 are used to push the cover body 4 downward so that the cover body 4 covers the top of the storage cart 1. In this way, when the crushing component crushes and discharges the road concrete, concrete particles and dust are difficult to overflow and are collected by the storage cart 1 as much as possible. When the storage cart 1 is full of crushed concrete, the water pump 3 is activated to spray water along the nozzle on the U-shaped tube 10 to perform dust reduction treatment on the air inside the cover body 4 above the storage cart 1 to reduce the overflow of dust when the storage cart 1 is replaced. With the help of the U-shaped guide plate 5, the storage cart 1 is accurately parked under the cover body 4. The second electric push rod 7 is activated to push the limit block 8 downward so that the limit block 8 can cooperate with the U-shaped guide plate 5 to lock the position of the storage cart 1. In this way, the cover body 4 can accurately cover the top of the storage cart 1 to reduce the overflow of dust when the concrete is discharged.

A transmission belt 17 is sleeved on the first pulley 15 and the second pulley 16.
[0030] The drive motor 14 is used to drive the second pulley 16 to rotate, so that the second pulley 16 pulls the first pulley 15 to rotate with the help of the transmission belt 17. The first pulley 15 drives the crushing roller 13 to rotate, so that the two crushing rollers 13 can rotate simultaneously under the drive of the two drive components to crush the road concrete blocks entering the crushing chamber 11.
[0031] Among them, the crushing bin 11 is provided with two symmetrically arranged reserved grooves 18, and a carrying column 19 is rotatably connected between the front and rear inner walls of the reserved groove 18 through a bearing. A baffle 20 and a carrying plate 21 are fixed to the outer wall of the carrying column 19. The baffle 20 is located inside the crushing bin 11, and the carrying plate 21 is located outside the crushing bin 11. The baffle 20 and the carrying plate 21 are symmetrically arranged about the carrying column 19. A traction rope 22 is fixed to the bottom of the carrying plate 21, and a counterweight 23 is fixed to the bottom end of the traction rope 22. Two symmetrically arranged stoppers 24 are fixed inside the crushing bin 11, and the stoppers 24 are located above the baffles 20;
[0032] When road concrete blocks are put into the crushing chamber 11, the concrete blocks can use their own gravity to squeeze the baffle 20 and rotate around the load column 19, so that the concrete blocks can fall under the baffle 20. After the concrete blocks are put into the chamber, the baffle 20 can be restored to a horizontal state with the help of the counterweight block 23 and the baffle 24. In this way, the feed port of the crushing chamber 11 can be blocked to reduce the overflow of the feed port of the crushing chamber 11 when the concrete is crushed.

[0035] Working principle of this utility model:
[0036] The equipment is fixed in the designated position, and the two driving motors 14 are enabled, so that the two driving motors 14 drive the two crushing rollers 13 to rotate, and push the storage trolley 1 to move. The storage trolley 1 can be parked under the cover 4 with the help of the U-shaped guide plate 5, and the second electric push rod 7 is enabled to extend, so that the second electric push rod 7 pushes the limit block 8 to move downward, and the limit block 8 cooperates with the U-shaped guide plate 5 to limit the storage trolley 1, so that when the two first electric push rods 2 push the cover 4 to move downward, the cover 4 can accurately cover the top of the storage trolley 1, and the two fit tightly, and the road concrete blocks are placed on the crushing trolley in an orderly manner using a forklift. Inside the crushing bin 11, after the concrete blocks enter the crushing bin 11, they will squeeze the baffle 20 under the action of their own gravity and rotate downward around the carrying column 19, so that the concrete blocks can fall under the baffle 20. When there are no concrete blocks above the baffle 20, the baffle 20 can return to a horizontal state with the help of the counterweight block 23 and the baffle 24. The two baffles 20 continue to block the feed port of the crushing bin 11, waiting for the next wave of concrete blocks to be added. Due to the blocking effect of the two baffles 20, the splashing gravel and dust generated when the concrete blocks are crushed are difficult to overflow from the feed port of the crushing bin 11.
[0037] The concrete blocks are crushed by the two crushing rollers 13, and the crushed concrete will be discharged along the discharge port of the crushing bin 11, and the discharged concrete will fall into the interior of the storage trolley 1, and the splashed dust will be blocked by the cover 4 and difficult to overflow. When the storage trolley 1 is full of crushed concrete, the two third electric push rods 25 are activated to retract, so that the two third electric push rods 25 pull the blocking plate 26 to block the crushing bin 11, and the crushing bin 11 no longer discharges material. The water pump 3 is activated to send city water to the U-shaped pipe 10, and water is sprayed along the nozzle on the U-shaped pipe 10 to spray water to reduce dust inside the cover 4 and soak the concrete on the top of the storage trolley 1 with water. In this way, the second electric push rod 7 and the two first electric push rods 2 are controlled to retract, and after the limit block 8 and the cover 4 move up, the storage trolley 1 can be transferred and replaced. At this time, only very little dust will overflow, effectively reducing the intrusion of dust on the surrounding environment and workers.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
