It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] See also Figure 1-5The utility model provides a technical solution: a stone crusher with dust collection function, comprising a crushing box 1, a feed port 2 is fixedly installed on the top of the crushing box 1, a motor 3 is fixedly installed on the left side of the crushing box 1, a rotating rod 4 is installed on the output end of the motor 3, a fixed block 5 is fixedly installed on the surface of the rotating rod 4, a crushing knife 6 is slidably connected to the bottom end of the fixed block 5, a filter box 7 is fixedly installed on the bottom end of the crushing box 1, a support column 8 is fixedly installed on the bottom end of the filter box 7, a fixed groove 9 is opened on the back of the filter box 7, a baffle 10 is slidably connected inside the fixed groove 9, a pulling block 11 is fixedly installed on the back of the baffle 10, a discharge port 12 is opened on the surface of the filter box 7, a fixed plate 13 is fixedly installed inside the filter box 7, and a The filter plate 14 and the right side of the filter box 7 are provided with a sliding groove 15, and the inside of the sliding groove 15 is slidably connected with a collection box 16, and a handle 17 is fixedly installed on the right side of the collection box 16. By setting the filter box 7, the support column 8, the fixed groove 9, the baffle 10, the pull block 11, the discharge port 12, the fixed plate 13, the filter plate 14, the sliding groove 15, the collection box 16 and the handle 17, a better use effect is achieved. During use, the stone to be crushed is first placed in the crushing box 1 through the feed port 2, so that the crushing knife 6 crushes it. After the crushing is completed, the pull block 11 is pinched and pulled backwards, so that the baffle 10 slides out of the filter box 7 through the fixed groove 9. At this time, the crushed large stone passes through the fixed plate 13 and the filter plate 14 and the discharge port 12. The dust particles will roll out of the filter box 7, and the smaller dust particles will fall into the collection box 16 through the filter plate 14, thus avoiding the situation that the dust generated by the crushing will fall on the ground during use, and the staff will need to perform secondary cleaning after the crushing is completed, as in the existing crusher, because the dust collection structure is not designed. The rotating rod 4 is rotatably connected to the crushing box 1, and the crushing knives 6 are evenly distributed on the surface of the rotating rod 4. The crushing knives 6 are rotatably connected to the crushing box 1, which makes it easier for the rotating rod 4 and the crushing knives 6 to rotate, and prevents the rotating rod 4 and the crushing knives 6 from being stuck by the crushing box 1 during use. The support columns 8 are evenly distributed at the four corners of the bottom of the filter box 7, and between the baffle 10 and the filter box 7 The sliding connection and the sliding connection between the pull block 11 and the filter box 7 make it easier for the baffle plate 10 to slide, thus preventing the baffle plate 10 from being stuck by the filter box 7 during use and causing the baffle plate 10 to be unable to continue sliding. The fixing plate 13 is provided with an inclined angle, and the filter plate 14 is provided with an inclined angle, which makes it easier for the crushed stones to be guided out of the filter box 7 during use and prevents the discharge port 12 from being blocked due to the crushed stones staying on the filter plate 14 during use. The collecting box 16 is slidingly connected to the filter box 7, and the handle 17 is slidingly connected to the filter box 7, which makes it easier for the collecting box 16 to slide, thus preventing the collecting box 16 from being stuck by the filter box 7 during use and causing the collecting box 16 to be unable to slide out of the filter box 7.

[0026] Embodiment 2

[0027] See also Figure 1-3 , 6. A mounting block 18 is fixedly installed at the bottom end of the fixing block 5. A rotating groove 19 is provided on the surface of the crushing knife 6. A bolt 20 is rotatably connected inside the rotating groove 19, which is more convenient for the staff to replace the crushing knife 6 after long-term use. If the crushing knife 6 needs to be replaced after long-term use, first use a tool to remove the bolt 20 and then pinch the crushing knife 6 and pull it downward to make the crushing knife 6 slide out of the mounting block 18. At this time, the new crushing knife 6 is placed inside the mounting block 18 and the bolt 20 is installed back through the rotating groove 19, thereby preventing the need to remove the rotating rod 4 as a whole when the crushing knife 6 needs to be replaced. The crushing knife 6 is slidably connected to the mounting block 18, the bolt 20 is rotatably connected to the crushing knife 6, and the bolt 20 is rotatably connected to the mounting block 18, which makes it more convenient for the bolt 20 to rotate, thereby preventing the bolt 20 from being stuck by the crushing knife 6 or the mounting block 18 during use, resulting in the bolt 20 being unable to continue to rotate.

[0028] Working principle: When in use, first place the crushing box 1 at the required position, so that the support column 8 can support the crushing box 1 steadily, and then place the stones to be crushed inside the crushing box 1 through the feed port 2, then start the motor 3, so that the rotating rod 4 drives the fixed block 5 and the crushing knife 6 to rotate inside the crushing box 1, and the crushing knife 6 can then crush the stones. After the crushing is completed, you can pinch the pulling block 11 and pull it backwards, so that the baffle 10 can slide backwards inside the filter box 7 through the fixed groove 9. When the baffle 10 completely slides out of the filter box 7, the crushed stones will fall down into the filter box 7. At this time, those larger stones will roll out of the filter box 7 through the fixed plate 13, the filter plate 14 and the discharge port 12, but Those smaller dusts will float down through the fixing plate 13 and fall into the collecting box 16. After the crushing is completed, hold the handle 17 and pull it backwards to make the collecting box 16 slide out of the filter box 7 through the sliding groove 15. When the collecting box 16 completely slides out of the filter box 7, the dust inside can be cleaned so that the collecting box 16 can be used. If the crushing knife 6 needs to be replaced after long-term use, first use a tool to remove the bolt 20, then pinch the crushing knife 6 and pull it downward to make the crushing knife 6 slide out of the mounting block 18, then place the new crushing knife 6 in the mounting block 18, and then rotate the bolt 20 corresponding to the rotating groove 19, so that the bolt 20 can firmly fix the crushing knife 6 in the mounting block 18 through the rotating groove 19.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
