[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0021] according to Figure 1-Figure 5 As shown, this embodiment provides a building material crushing device, including a feeding base 1, as shown in FIG. Figure 3 and Figure 5As shown, the feeding base 1 includes two groups of symmetrically arranged support seats 10, a conveyor belt 11 is arranged between the two groups of support seats 10, a conveyor belt roller 12 is arranged on the inner side of the conveyor belt 11, and the conveyor belt roller 12 is evenly arranged in a plurality of groups. In this embodiment, nine groups of conveyor belt rollers 12 are evenly arranged, and both ends of the conveyor belt roller 12 shaft are connected to the support seats 10 on both sides through bearings, wherein the nine groups of conveyor belt rollers 12 are driven by a conveyor belt motor. Specifically, among the nine groups of conveyor belt rollers 12, the outermost two groups of conveyor belt rollers 12 are used as driving rollers, which are driven by independent conveyor belts. The conveyor belt motor is driven by the conveyor belt motor, and the conveyor belt motor is located on the outside of the support base 10 and is fixedly connected to the support base 10 through a bracket. Therefore, when working, the conveyor belt motor is started, and then the conveyor belt 11 is driven to rotate through the conveyor belt roller 12. A collection box 2 is placed on the feeding base 1, that is, the collection box 2 is placed on the conveyor belt 11, and its position changes with the rotation of the conveyor belt 11. When it enters just below the crushing box 3, it is in a loading state. After it is full, it is moved out. At the same time, a new set of collection boxes 2 can be placed for the next round of aggregation.

[0022] A limit assembly is installed on the support seat 10, and the limit assembly includes a limit baffle 19, which passes through the support seat 10. An electric push rod 20 is installed on the support seat 10, and the telescopic end of the electric push rod 20 is connected to the limit baffle 19 through a fixed block, such as Figure 3 and Figure 4 As shown, the limit baffle 19 can move horizontally above the conveyor belt 11, and its movement is limited by the electric push rod 20. During operation, in order to ensure that the aggregate box 2 can correctly enter the predetermined position, the electric push rod 20 is started, and the telescopic end of the electric push rod 20 is retracted, so that the limit baffle 19 follows the movement. At this time, the limit baffle 19 is located in the forward direction of the aggregate box 2, thereby blocking the aggregate box 2. When the aggregate box 2 needs to move forward, the electric push rod 20 is started again, and the telescopic end of the electric push rod 20 is extended. At this time, the position of the limit baffle 19 changes, and no limiting effect is produced, so the aggregate box 2 can move forward normally.

[0023] A crushing box 3 is installed above the feeding base 1. Furthermore, a limiting slot 23 is provided on the support seat 10, and a supporting plug plate 24 is provided on the inner side of the limiting slot 23, and the supporting plug plate 24 is connected to the crushing box 3. Therefore, two groups of symmetrically arranged supporting plug plates 24 are provided at the bottom of the crushing box 3. During installation, the cooperation between the supporting plug plates 24 and the limiting slots 23 can achieve a positioning effect. Further, after installation, the supporting plug plates 24 and the support seat 10 are fixedly connected by bolts to enhance the stability of the crushing box 3 after installation.

[0024] A feed port 4 is provided at the upper end of the crushing box 3 for the entry of building materials, and dust collecting components are installed on both sides of the crushing box 3. Figure 1 and Figure 2 As shown, the dust collecting assembly includes a dust collecting box 13, a dust intercepting net 14 is installed on the inner side of the dust collecting box 13, and three groups of dust intercepting nets 14 are provided.

At the same time, two groups of symmetrically arranged air collecting hoods 21 are installed on the inner side of the crushing box 3, and the air collecting hoods 21 are connected to the air intake pipe 16. Dust will be generated in the process of crushing building materials. Therefore, the device can absorb and filter the smoke generated in the crushing box 3 and then discharge it through the cooperation of the dust suction air pump 15 (exhaust pump), the air intake pipe 16, the dust collecting box 13, the dust intercepting net 14 and the air collecting hood 21, thereby reducing the impact of the smoke on the external environment.

[0025] A first crushing roller 5 and a second crushing roller 6 are installed on the inner side of the crushing box 3. The first crushing roller 5 and the second crushing roller 6 are symmetrically provided with two groups. A cutting roller 7 is provided below the second crushing roller 6. The surface of the cutting roller 7 is provided with cutting spikes 8, and the cutting spikes 8 are evenly provided with a plurality of groups.

The independent motors are located on the outer side of the crushing box 3 and are connected to the crushing box 3 through a bracket. That is, in this device, five groups of independent motors are provided, such as Figure 1 As shown, the first crushing roller 5 is responsible for the first stage crushing. When working, the building materials enter between the two groups of first crushing rollers 5 through the feed port 4, and are crushed by the first crushing roller 5. The crushed building materials directly fall between the two groups of second crushing rollers 6. The second crushing roller 6 is used for the second stage crushing. After crushing, it contacts with the cutting roller 7 in a high-speed rotating state, so as to use the force generated by the collision to perform the third stage crushing. A discharge port 9 is provided at the lower end of the crushing box 3, and the crushed building materials enter the aggregate box 2 through the discharge port 9. Furthermore, the surfaces of the first crushing roller 5 and the second crushing roller 6 are provided with crushing protrusions, and the crushing protrusions are evenly distributed in several groups. When the distribution spacing of the crushing protrusions on the first crushing roller 5 is greater than the distribution spacing of the crushing protrusions on the second crushing roller 6.

[0026] Shielding plates 17 are provided on both sides above the cutting roller 7. The shielding plates 17 are inclined and fixedly connected to the crushing box 3. A through opening 18 is provided on the shielding plates 17. The shielding plates 17 are mainly used to prevent the crushed building materials from flying to the top of the crushing box 3. At the same time, through the through opening 18, even if a similar situation occurs, the splashed building materials can enter the bottom of the crushing box 3 through the through opening 18. Two groups of symmetrically arranged guide plates 22 are installed at the bottom of the inner side of the crushing box 3.
