[0021] Example 1

[0022] like Figure 1~Figure 2As shown, this embodiment proposes a construction solid waste crusher, including a crusher body 1, a feeding port 2 is opened at the upper end of the crusher body 1, a crushing mechanism 3 is installed in the crusher body 1, a protective mechanism 4 is installed at the upper end of the crusher body 1, an inclined plate 5 is fixedly installed on the inner wall of the crusher body 1, a discharge port 6 is opened at one end of the crusher body 1, and the crushing mechanism 3 includes a driving motor 301, a motor wheel 302, a pulley 303, a belt 304, a bearing 305, an eccentric shaft 306, and a movable The jaw 307, the fixed jaw 308, the pull rod 309, the fixed plate 310, the pull rod spring 311, the driving gear 312, the driven gear 313 and the crushing roller 314, the crusher body 1 is fixedly installed with a driving motor 301 at one end, the output end of the driving motor 301 is fixedly connected with a motor wheel 302, the motor wheel 302 is fixedly installed with a driving gear 312 at one end away from the driving motor 301, the driving gear 312 is meshed with the driven gear 313, and the driving gear 312 and the driven gear 313 are connected. A crushing roller 314 is fixedly installed on the inner wall of the crusher body 1 at one end, a belt 304 is sleeved on the surface of the motor wheel 302, a pulley 303 is symmetrically installed above the motor wheel 302, a belt 304 is sleeved between the pulley 303 and the motor wheel 302, an eccentric shaft 306 is fixedly installed on one end of the pulley 303, bearings 305 are symmetrically fixedly installed on both ends of the eccentric shaft 306, a movable jaw 307 is fixedly sleeved on the outer surface of the eccentric shaft 306, and one side of the movable jaw 307 is located at the crusher body A fixed jaw 308 is fixedly installed on the inner wall, a pull rod 309 is fixedly installed on one end of the movable jaw 307 away from the fixed jaw 308, the other end of the pull rod 309 is movably installed in the middle of the fixed plate 310, and a pull rod spring 311 is movably installed on the other end of the fixed plate 310. The crushing roller 314 and the movable jaw 307 rotate through the cooperation between the driving motor 301 and the driving gear 312, the driven gear 313, the motor wheel 302, and the pulley 303, and a magnet is fixedly installed on the surface of the inclined plate 5.

[0023] In this embodiment, the motor wheel 302 and the crushing roller 314 are rotated by the driving motor 301 during driving, and then the concrete is poured into the loading port 2. When the driving motor 301 is running, the driving gear 312 is driven to rotate, and the driving gear 312 is meshed and connected to the driven gear 313, so that when the driving gear 312 rotates, the driven gear 313 can be driven to rotate synchronously, and the driving gear 312 and the driven gear 313 drive the corresponding crushing roller 314 to rotate. Secondly, the driving motor 301 drives the motor wheel 302 to rotate, and then the crushing roller 314 is driven to rotate by the driving gear 312 and the driven gear 313. At the same time, the motor wheel 302 rotates through the belt 304 so that the pulley 303 can rotate together. The pulley 303 is connected to the eccentric shaft 306. When rotating, the eccentric shaft 306 moves to drive the movable jaw 307, and the eccentric shaft 306 drives the movable jaw 307 to rotate. The movable jaw 307 moves up and down. When the movable jaw 307 rises, the angle becomes larger, thereby pushing the movable jaw 307 to approach the fixed jaw 308. At the same time, the material is crushed or split to achieve the purpose of crushing. The purpose of setting the pull rod spring 311 is to provide a buffer for the movable jaw 307 during the reciprocating movement to avoid damage caused by long-term processing. The concrete is crushed by the cooperation of the movable jaw 307 and the fixed jaw 308, and then falls into the crushing roller 314. After being rolled by two sets of crushing rollers 314, the quality of the concrete after the crushing process is improved, and the crushed concrete falls onto the surface of the inclined plate 5. The inclined plate 5 is at an inclined angle, which is convenient for the crushed concrete to fall out of the discharge port 6. The purpose of setting the magnet is that there will be iron objects such as steel bars in the concrete. After the steel bars are attracted, the discharged concrete does not need to be screened by manpower, which is more convenient.

[0024] Example 2

[0025] like Figure 3~Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes a construction solid waste crusher, the protection mechanism 4 includes a safety cover 401, a transparent glass 402, a T-shaped slider 403, a slide groove 404, a through hole 405 and a fixed rod 406, the safety cover 401 is slidably connected to the upper end of the feeding port 2, and the transparent glass 402 is fixedly installed on one end of the safety cover 401, the crusher body 1 is symmetrically provided with slide grooves 404 at both ends near the feeding port 2, the safety cover 401 is symmetrically provided with T-shaped sliders 403 at the lower end, the crusher body 1 and one end of the T-shaped slider 403 are provided with through holes 405, the inner wall of the through hole 405 is symmetrically and movably connected with a fixed rod 406, the top of the T-shaped slider 403 is in contact with the slide groove 404, and the slide groove 404 is provided with a notch at one end away from the bearing 305.

[0026] In this embodiment, the safety cover 401 is first pulled, and the top of the T-shaped slider 403 at the lower end coincides with the slide groove 404, and is threadedly connected to the through hole 405 through the fixing rod 406 to achieve a fixing effect. The purpose of setting the transparent glass 402 is to observe the state of crushing through the transparent glass 402 during processing. When adding materials, the fixing rod 406 is twisted to remove it from the through hole 405, and the safety cover 401 is pulled until the top of the T-shaped slider 403 is fitted with the fixed block at one end of the slide groove 404 to perform the adding operation, which effectively avoids the splashing of fragments during the crushing process and ensures the safety of the staff.

[0027] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0028] When working, the fixing rod 406 is twisted to be taken out from the through hole 405, and then the safety cover 401 is closed until the top of the T-shaped slider 403 is fitted with the fixing block at one end of the slide groove 404, and the driving motor 301 is started to rotate the motor wheel 302 and the crushing roller 314, and the driving gear 312 is meshed with the driven gear 313, and the crushing roller 314 is driven to operate during operation. The motor wheel 302 drives the pulley 303 through the transmission of the belt 304, and the concrete is poured from the loading port 2, and the safety cover 401 is pushed to overlap the T-shaped slider 403 with the through hole 405. The fixing rod 406 is screwed to fix the safety cover 401, and the pulley 303 drives the eccentric shaft 306 to move the movable jaw 307 up and down. When the movable jaw 307 rises, the angle becomes larger, thereby pushing the movable jaw 307 to approach the fixed jaw 308. At the same time, the concrete is crushed or split, and then falls to the crushing roller 314 for rolling. After the processing, the concrete falls to the surface of the inclined plate 5 and slides to the discharge port 6, which can prevent the fragments from splashing out during processing to cause harm to the workers, thereby improving safety issues and improving the quality of the crushed concrete.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
