[0002] Concrete aggregate refers to the granular loose material that acts as a skeleton or filling in concrete. It is divided into coarse aggregate and fine aggregate. Coarse aggregate refers to pebbles, crushed stones, etc., and fine aggregate refers to natural sand, artificial sand, etc. When processing aggregate, an aggregate crusher is needed to crush it.

[0003] According to the announcement number CN219663971U, an aggregate crusher for producing concrete is disclosed. The aggregate crusher for producing concrete has a crusher housing, a fixed block, a connecting plate, a filter screen, a vibrating block, a fixed plate and a collecting box. The filter screen can effectively filter the crushed aggregate, so that it has higher quality in the subsequent use process, making people feel more at ease when using it, further meeting people's use needs, and bringing convenience to people's work. When the above device is in use, since the distance between the crushing roller and the fixed block is fixed, it is not convenient to adjust the device, and thus cannot meet the processing and use of aggregates of different specifications, so the practicality of the wet device is low.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1 Please refer to Figure 1-Figure 5 , the utility model provides a technical solution:

[0024] A concrete aggregate crusher comprises a box body 1, a vertical plate 2 is fixedly provided on one side of the box body 1, a feed hopper 3 is fixedly provided on the top of the side of the box body 1 away from the vertical plate 2, a crushing seat 4 is fixedly provided on the middle inner wall of the box body 1, a fixing ring 5 is fixedly provided on the lower inner wall of the box body 1, a filter plate 6 is fixedly provided on the lower inner wall of the fixing ring 5, a discharge pipe 7 is fixedly provided on the bottom end of the box body 1, a support 8 is slidably provided on the upper part of one side of the vertical plate 2 close to the box body 1, a rotating rod 9 is rotatably embedded in the bottom end of the support 8, a crushing roller 10 matching the crushing seat 4 is fixedly sleeved on the lower part of the rotating rod 9, a connecting rod 11 is slidably embedded in the bottom end of the rotating rod 9, and a scraper 12 is fixedly provided on the lower part of one side of the connecting rod 11.

[0025] Specifically, Figure 1-Figure 5As shown, a slide groove 13 is provided on the upper part of one side of the vertical plate 2 close to the support 8, and a motor 14 is fixedly provided on the inner wall of the bottom end of the slide groove 13. A screw rod 15 is fixedly connected to the output end of the motor 14. A slider 16 is threadedly sleeved on the screw rod 15. The slider 16 is fixedly connected to the side adjacent to the support 8. The slider 16 is slidably connected to the slide groove 13. A threaded seat matching the screw rod 15 is fixedly embedded on the slider 16. The screw rod 15 can be driven to rotate by the motor 14. At this time, the screw rod 15 will drive the slider 16 to move in the slide groove 13, so that the slider 16 drives the support 8 to move up and down.

[0026] Specifically, Figure 1-Figure 5 As shown, a second motor 17 is fixedly provided on the inner wall of the bottom end of one side of the support 8, and the top end of the rotating rod 9 extends into the support 8. A pulley 18 is fixedly provided at the output end of the second motor 17 and the upper part of the rotating rod 9. The two pulleys 18 are connected by a belt 19. The second motor 17 can drive the corresponding pulley 18 to rotate, so that the pulley 18 drives another pulley 18 to rotate through the belt 19. At this time, the pulley 18 will drive the rotating rod 9 to rotate, so that the rotating rod 9 drives the crushing roller 10 to rotate.

[0027] Specifically, Figure 1-Figure 5 As shown, a cavity 20 is opened in the lower part of the rotating rod 9, and a limit block 21 is slidably provided in the cavity 20. The top end of the connecting rod 11 extends into the cavity 20 and is fixedly connected to the bottom end of the limit block 21. A spring 22 is fixedly provided at the top end of the limit block 21. The top end of the spring 22 is fixedly connected to the top inner wall of the cavity 20. The cross-sections of the limit block 21 and the cavity 20 are both rectangular structures. The limit block 21 can be pushed downward by the spring 22, so that the limit block 21 drives the scraper 12 to move downward through the connecting rod 11 until it contacts the filter plate 6. When the rotating rod 9 rotates, the rotating rod 9 will drive the connecting rod 11 and the scraper 12 to rotate through the limit block 21, so that the scraper 12 can scrape the material on the filter plate 6, thereby facilitating the material to pass through the filter plate 6 and fall into the discharge pipe 7 and be discharged.

[0028] Example 2 Please refer to Figure 2 The difference between this embodiment and the first embodiment is that the inner wall of the bottom end of the box body 1 and the upper part of the crushing roller 10 are both funnel-shaped structures, and the funnel-shaped structure is provided to facilitate the falling of materials.

[0029] The working principle of the utility model is as follows: when in use, the material is placed in the feed hopper 3 and then dropped into the box body 1. At this time, the corresponding pulley 18 can be driven to rotate by the motor 2 17, so that the pulley 18 drives another pulley 18 to rotate through the belt 19. At this time, the pulley 18 will drive the rotating rod 9 to rotate, so that the rotating rod 9 drives the crushing roller 10 to rotate, so that the material can be crushed by the crushing roller 10 and the crushing seat 4. The crushed material will be filtered through the filter plate 6 and fall into the discharge pipe 7. When the device needs to be adjusted, the screw 15 can be driven to rotate by the motor 1 14. At this time, the screw 15 will drive the slider 16 to move in the slide 13, so that the slider 16 drives the support 8 to move up and down, so that the gap between the crushing roller 10 and the crushing seat 4 can be adjusted, so as to facilitate the production of materials of different specifications. When the rotating rod 9 moves, the spring 22 can be used to ensure that the scraper 12 is always in contact with the filter plate 6, so as to facilitate the scraping of the material for filtering.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
