[0030] A buffer protection mechanism is provided, and the buffer protection mechanism includes an elastic connection component and a support component. The elastic connection component is arranged at the connection between the end of the dividing plate 108 and the inner surface of the feed box 102, and the support component is arranged on the inner side of the feed box 102 and at the lower surface of the dividing plate 108. When the gravel crusher body 100 is processing larger stones entering through the feed box 102, powder enters the dividing plate 108. When the lower surface of the dividing plate 108 is affected by flying stones, the buffer protection mechanism buffers and protects the dividing plate 108, which is not easily damaged by impact, thereby improving the elastic buffer protection effect of the gravel crusher body 100 on the dividing plate 108 when crushing stones in concrete processing and production.

[0031] In order to facilitate elastic buffering of the lower surface of the dividing plate 108 when it is hit by an elastic connection component, and to facilitate buffering protection, in the present embodiment, preferably, the elastic connection component includes a fixed plate 1081 welded and fixed on both sides of the bottom end of the feed box 102, so that the dividing plate 108 can be easily installed through the fixed plate 1081 for use, and is convenient for elastic installation. A connecting shaft 1083 is provided at the connection between the interior of the fixed plate 1081 and the dividing plate 108, and torsion springs 1084 are installed at both ends of the connecting shaft 1083, and the dividing plate 108 and the interior of the fixed plate 1081 are elastically and tightly connected through the connecting shaft 1083 and the torsion spring 1084. When the lower surface of the dividing plate 108 is hit by flying stones, the torsion spring 1084 is deformed when the dividing plate 108 is subjected to force, and the connecting shaft 1083 is rotated in situ to elastically connect the dividing plate 108, so as to facilitate elastic buffering of the dividing plate 108.

[0032] In order to facilitate the support of the dividing plate 108 through the support assembly and to ensure stable material unloading, in the present embodiment, preferably, the support assembly includes a support plate 1082 which is fixed by bolts on the lower surface of the fixing plate 1081 and is located on the inner side of the feed box 102, and the end of the support plate 1082 is consistent with the lower surface structure of the dividing plate 108, and the dividing plate 108 is elastically connected and is pressed tightly against the surface of the support plate 1082, so as to facilitate tight support.

[0033] The working principle and use process of the utility model are as follows: when the stone crusher for concrete processing is in use, the stone crusher body 100 is stably placed at the position of concrete processing and production through the bottom end of the crushing box 101 contacting the ground, the main motor 104 is moved, and the larger stones enter the crushing box 101 through the feed box 102 and enter through the dividing plate 108. After entering, the main motor 104 drives the crushing roller 107 to rotate, so that the two crushing rollers 107 move towards each other to crush the larger stones entering to form stones. The stones fall on the surface of the screen 106 and are vibrated by the vibration motor to screen the crushed stones. The qualified stones pass through the screen 106 and fall to the bottom and are discharged from the discharge port 105. The unsuitable stones enter the interior of the installation box 103 from the end that passes through the screen 106, and are lifted to the top by the operation of the screw conveying mechanism 109 and enter the crushing box 101 again for re-crushing.

[0034] Then, before the stone crusher body 100 is used, the end of the clamping plate 1060 and the end of the screen 106 can be passed through the installation slot 1062 into the interior of the crushing box 101 until the end of the clamping plate 1060 is engaged in the interior of the clamping slot 1069, the reinforcing connecting plate 1061 is closed in the interior of the installation slot 1062 to engage and install the screen 106, and the internal threaded rotating wheel 1063 is rotated at the end of the threaded rod 1068 to drive the threaded rod 1068 to move, and the threaded rod 1068 moves to the internal limit displacement of the control slide hole 1067. The reinforcing connecting plate 1061 is reinforced in the installation groove 1062 by moving until it is engaged in the clamping hole 1066, and the clamping plate 1060 is reinforced in the clamping groove 1069 by the same operation, so that the screen 106 can be fixedly installed and used. Therefore, when the surface of the screen 106 is damaged by impact due to the long-term crushing operation of the stone crusher body 100, the reverse operation can be performed to disassemble and repair it, and the disassembly and assembly and maintenance are convenient and simple to operate, which improves the convenience of disassembly and replacement of the screen 106 when the stone crusher body 100 processes and produces concrete and crushes stones;

[0035] Finally, when the stone crusher body 100 is processing concrete, the dividing plate 108 is elastically pressed against the surface of the support plate 1082 and supports it, and the material is guided down through the dividing plate 108 when the material is discharged through the feed box 102. Therefore, when the stone crusher body 100 is in crushing operation after feeding, the stone is crushed internally and produces flying, causing the stone to hit the lower surface of the dividing plate 108. The dividing plate 108 is subjected to force and deformed by the torsion spring 1084, driving the connecting shaft 1083 to rotate in situ to elastically move the dividing plate 108 upward for buffering protection. After the force is applied, the dividing plate 108 is automatically restored to its original position and supported by the support plate 1082, so that the dividing plate 108 is easy to buffer and protect during powder processing, and is not easily deformed and damaged when hit during the internal crushing process. The elastic buffering and protection effect of the dividing plate 108 of the stone crusher body 100 on crushing stone in concrete processing is improved, thereby extending the service life.

[0036] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
