Detailed Implementation

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0020] Existing pulverizing wheels, when crushing smaller concrete particles, only serve as a secondary crusher and cannot guarantee that the particles will reach the preset particle size. This results in significant differences in particle size after crushing, which affects subsequent processing or use. For example, in concrete recycling, uniform particle size is required for further processing or to ensure consistent material quality. Please refer to [link / reference]. Figures 1-3 This embodiment provides a concrete block crushing device, including a crushing box 2 and a connecting slide 3 disposed on the side of a crushing box 1. The crushing box 1 and the crushing box 2 are connected by the connecting slide 3. A crushing mechanism 4 is disposed inside the crushing box 1. The crushing mechanism 4 includes two crushing wheels 41 rotating inside the crushing box 1. A drive assembly 42 is disposed outside the crushing box 1 to make the two crushing wheels 41 rotate relative to each other. The drive assembly 42 includes two gears 422 rotating outside the crushing box 1. Two rotating shafts are fixed to the inner walls of the two gears 422. The two crushing wheels 41 are respectively fixed to the outer walls of the two rotating shafts. A dual-head motor 421 is fixed to the outside of the crushing box 1. One of the gears 422 is fixed to the outer wall of one of the output ends of the dual-head motor 421. Two toothed baffles 43 adapted to the two crushing wheels 41 are symmetrically fixed to the inner wall of the crushing box 1. After the lumpy concrete is fed into the crushing chamber 1, the dual-head motor 421 is started, causing one of its output ends to drive the gear 422 to rotate, which in turn drives the other gear 422, achieving relative rotation of the two crushing wheels 41 to crush the lumpy concrete. Simultaneously, two toothed baffles 43 inside the crushing chamber 1, adapted to the crushing wheels 41, help keep the lumpy concrete within the crushing zone, preventing uncrushed lumps from falling from the sides, thus ensuring they continue to contact the crushing wheels 41 for effective crushing and improving crushing efficiency.

[0021] like Figure 2 and Figure 3As shown, the crushing mechanism 5 driven by the crushing mechanism 4 in synchronization, the crushing mechanism 5 includes a centrifugal cylinder 51 rotating inside the crushing box 2, the outside of the crushing box 2 is provided with a linkage assembly 53 for rotating the centrifugal cylinder 51 to screen and crush the concrete lumps, the linkage assembly 53 includes a linkage shaft 531 fixed to the outer wall of the other output end of the double-head motor 421, the inner wall of the centrifugal cylinder 51 is fixed with a power shaft 533, an installation frame 521 is fixed to the outer wall of the power shaft 533, a transmission assembly is arranged between the linkage shaft 531 and the power shaft 533, the transmission assembly includes a belt pulley one fixed to the outer wall of the linkage shaft 531, the outer wall of the belt pulley one is provided with a belt 532, the belt pulley one is drivingly connected with a belt pulley two through the belt 532, and the belt pulley two is fixed to the outer wall of the power shaft 533. After being processed by the crushing mechanism 4, the lumpy concrete enters the centrifugal cylinder 51 through the communication chute 3, the communication chute 3 is cylindrically arranged, one end of the communication chute 3 is rotatably connected to the inside of the centrifugal cylinder 51, and the communication chute 3 does not extend into the inside of the centrifugal cylinder 51, which ensures that the crushed concrete can be effectively conveyed to the crushing mechanism 5 for further processing. The other output end of the double-head motor 421 drives the linkage shaft 531 to rotate, the power shaft 533 is synchronously rotated through the transmission of the belt 532, and then the centrifugal cylinder 51 is rotated, this rotating power mode can ensure the efficient operation of the centrifugal cylinder 51, after the centrifugal cylinder 51 rotates, the concrete particles meeting the size requirements are thrown out of the centrifugal cylinder 51 due to the centrifugal force, and the concrete particles not meeting the size requirements are intercepted in the centrifugal cylinder 51 by the centrifugal force and cannot pass through the cylinder hole or be thrown out. Since the bottom of the centrifugal cylinder 51 is inclined, it helps the concrete particles meeting the size requirements to smoothly slide out, so as to be distinguished from the particles not meeting the size requirements.

[0022] As Figure 3As shown, the inside of the centrifugal cylinder 51 is provided with a hammering assembly 52 for re-pulverizing the intercepted concrete lumps under the synchronous driving of the linkage assembly 53, the hammering assembly 52 comprises a mounting frame 521 arranged in the inside of the centrifugal cylinder 51, the inside of the mounting frame 521 is rotationally connected with a rotating rod 522, a plurality of gravity plates 523 are fixed on the outer wall of the rotating rod 522 in equal distance laterally, and a plurality of conical protrusions 524 are symmetrically fixed on the two sides of the gravity plates 523. When the concrete particles that do not meet the specifications are intercepted in the centrifugal cylinder 51, with the rotation of the centrifugal cylinder 51, the particles will roll along the inner wall of the centrifugal cylinder 51. At this time, the gravity plates 523 in the centrifugal cylinder 51 will swing through the rotating rod 522 with the rotation of the centrifugal cylinder 51, and the multiple conical protrusions 524 on the outer wall of the gravity plates 523 are used to contact the particles that do not meet the specifications through the hard surface and sharp shape, so as to generate impact force and extrusion effect, and gradually crush the particles, in the process, the particles gradually become smaller, until their size meets the requirements of passing through the cylinder screen, and after the pulverizing effect of the gravity plates 523 and the conical protrusions 524, the particles that do not meet the specifications will finally be crushed to the appropriate size, and can pass through the cylinder hole of the centrifugal cylinder 51 or be directly thrown out of the centrifugal cylinder 51.

[0023] The above is only the preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
