[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] Please refer to Figure 1 , Figure 2 and Figure 3 , a crusher for building construction, comprising: a broken box 1, two broken rollers 6 are arranged in the broken box 1, two drive motors 5 are installed on one side of the broken box 1, the output ends of the two drive motors 5 are connected with the two broken rollers 6, and a material box 4 is installed on the top of the broken box 1.

[0029] Please refer to Figure 2 - Figure 6The barrier mechanism 2 is located in the inside of the crushing box 1 and is used for filtering the crushed materials. The barrier mechanism 2 comprises a barrier filter plate 7 fixed in the inside of the crushing box 1, a pushing assembly located at one side in the inside of the crushing box 1 and used for pushing the filtered materials, an opening and closing assembly located at one side in the inside of the crushing box 1 relative to the pushing assembly and used for opening and closing the space in the inside of the crushing box 1, and a jacking assembly located at both sides of the bottom of the barrier filter plate 7 and used for jacking the filter holes in the inside of the barrier filter plate 7. The jacking assembly comprises rotating shafts 213 installed at both sides in the inside of the crushing box 1 and rotating plates 214 installed at the bottom of the rotating shafts 213. Both sides in the inside of the crushing box 1 are provided with grooves for accommodating the rotating plates 214. One side of each rotating plate 214 is fixed with a plurality of rubber contact blocks 215 uniformly distributed. The rubber contact blocks 215 correspond to the filter holes in the inside of the barrier filter plate 7. One side of each rotating shaft 213 is provided with a control assembly for controlling the rotation of the rotating plate 214. The opening and closing assembly comprises an opening and closing opening provided at one side of the crushing box 1. The top of the opening and closing opening is provided with a groove. The groove is internally provided with an opening and closing plate 23 corresponding to the opening and closing opening. The top of the opening and closing plate 23 is fixed with two counterweights 25 and two ropes 28. The two ropes 28 extend to one side of the top of the crushing box 1 and are jointly fixed with a control plate 26. One side of the crushing box 1 is fixed with a baffle corresponding to the control plate 26. The top of the crushing box 1 is fixed with two guide seats 27 matched with the ropes 28. The pushing assembly comprises an opening groove provided at one side in the inside of the crushing box 1. The opening groove is internally provided with a push plate 22. One side of the crushing box 1 is fixed with an electric push rod 21. The extension end of the electric push rod 21 extends to the inside of the opening groove and is connected with the push plate 22. The push plate 22 corresponds to the opening and closing plate 23.

[0030] When the materials are crushed and fall on the top of the barrier filter plate 7, the completely crushed materials are separated from the incompletely crushed materials through the filter holes, so that the incompletely crushed materials are accumulated on the top of the barrier filter plate 7. When the incompletely crushed materials need to be discharged, the rotating shaft 213 is first rotated to drive the rotating plate 214 to rotate. The rotation of the rotating plate 214 drives the rubber contact blocks 215 to rotate synchronously. The rubber contact blocks 215 are arranged to abut against the filter holes in the inside of the barrier filter plate 7, so as to push out the materials remaining in the inside of the barrier filter plate 7. The control plate 26 is pulled to drive the ropes 28 to move in the guide seats 27. The movement of the ropes 28 drives the opening and closing plate 23 to move. The movement of the opening and closing plate 23 separates the opening and closing plate 23 from the opening and closing opening, so that the opening and closing opening is opened. Similarly, the counterweights 25 can be used to reset the opening and closing plate 23. Then, the electric push rod 21 drives the push plate 22 to move on the top of the barrier filter plate 7. The continuous movement of the push plate 22 enables the materials accumulated on the top of the barrier filter plate 7 to be discharged through the opening and closing opening.

[0031] Further, as shown in Figure 4 , the control assembly includes an arc slot opened on one side of the crushing box 1, the rotating shaft 213 extends to one side of the crushing box 1 and is fixed with a control block 29, one side of the control block 29 is fixed with a sliding block 24 matched with the arc slot, and the inside of the arc slot is provided with a positioning assembly for positioning the sliding block 24; based on this, pulling the control block 29 drives the sliding block 24 to move in the arc slot, and through the mutual cooperation of the control block 29 and the sliding block 24, the rotating shaft 213 drives the rotating plate 214 to rotate more smoothly.

[0032] Further, as shown in Figure 5 , the positioning assembly includes two receiving grooves opened on one side of the arc slot, and two positioning blocks 210 corresponding to the sliding block 24 are installed inside the two receiving grooves. The two positioning blocks 210 and the receiving grooves are connected with extrusion springs 211, and one side of the two positioning blocks 210 is fixed with a movable rod, the movable rod extends to the bottom of the receiving groove and is fixed with a moving plate 212, and one side of the crushing box 1 is provided with a moving groove for the moving plate 212 to move; based on this, when the sliding block 24 needs to slide in the arc slot, first pull the moving plate 212 to drive the movable rod to move, through the movement of the movable rod to drive the positioning block 210 to move, through the movement of the positioning block 210 to drive the extrusion spring 211 to contract, through the contraction of the extrusion spring 211, the positioning block 210 can enter the receiving groove, when the positioning block 210 enters the receiving groove, it is separated from the sliding block 24, so that the sliding block 24 can slide in the arc slot.

[0033] In addition, please refer to Figure 2 , Figure 3 and Figure 7 , the inside of the crushing box 1 is provided with a watering mechanism 3 for watering the two crushing rollers 6, the watering mechanism 3 includes a water tank 31 fixed on one side of the crushing box 1, two water supply pumps 32 are installed inside the water tank 31, guide blocks 33 corresponding to the two crushing rollers 6 are fixed on both sides of the crushing box 1, the inside of the guide block 33 is provided with a water storage pipe 35, and the bottom of the water storage pipe 35 is fixed with a plurality of evenly distributed spray pipes 36, the plurality of spray pipes 36 correspond to the crushing rollers 6, and the water outlet of the two water supply pumps 32 and the water storage pipe 35 are connected with water supply pipes 34.

[0034] The water source in the water tank 31 is delivered to the water supply pipe 34 by the two water supply pumps 32, the water source is delivered to the water storage pipe 35 by the water supply pipe 34, and then sprayed out by the plurality of spray pipes 36, so that the outer wall of the crushing roller 6 can be effectively watered.
