The top end of the falling groove 11 is arranged at the bottom of the feed hopper 4. Two meshing transmission wheels 12 are movably connected to the upper front side of the inner wall of the falling groove 11. A first motor 13 is fixedly connected to the upper front side inside the falling groove 11. The output shaft of the first motor 13 is fixedly connected to the front side of the right transmission wheel 12. A material crushing roller 14 is fixedly connected to the rear side of the transmission wheel 12. A filter screen plate 15 is fixedly connected to the lower part of the inner surface of the falling groove 11. A scraping mechanism 16 is slidably connected to the top of the filter screen plate 15. Three material lifting grooves 17 are opened on both the left and right sides below the falling groove 11. A material guiding groove 18 is opened at the top of the three material lifting grooves 17. One end of the material guiding groove 18 away from the material lifting groove 17 penetrates through to the upper part of the inner surface of the falling groove 11;

[0026] When crushing limestone, the limestone to be crushed is fed into the falling groove 11 through the feed hopper 4. By starting the first motor 13, the transmission wheel 12 can drive the material crushing roller 14 to crush the limestone. The crushed limestone will fall on the filter screen plate 15 for filtering. The limestone with a larger volume will fall into the inside of the material lifting groove 17 under the scraping of the scraping mechanism 16, and under the lifting of the lifting mechanism 5, it can fall from the material guiding groove 18, so as to perform secondary crushing of the limestone through the material crushing roller 14, making the crushing effect of the limestone better. And the limestone with a larger volume will pass through the filter screen plate 15 and fall into the collection box 3 inside the placement bin 2, completing the crushing process of the limestone.

[0027] Such as Figure 3-4As shown in the figure, the utility model provides a limestone crushing device. The scraping mechanism 16 includes two connecting frames 161, which are respectively fixedly connected to the front and rear sides of the filter screen plate 15. An axially-through sliding groove 1 is formed above the interior of the connecting frame 161. On the left inner wall of the sliding groove 1, a second motor 162 is fixedly connected. The output shaft of the second motor 162 is fixedly connected with a transmission screw 163. A threaded slider 164 is threadedly connected to the outer surface of the transmission screw 163. The threaded slider 164 is slidably connected inside the sliding groove 1. A sliding scraper 165 is fixedly connected to the opposite surfaces of the two threaded sliders 164. The sliding scraper 165 is slidably connected to the top of the filter screen plate 15. A number of L-shaped sliding plates 166 are slidably connected inside the connecting frame 161. The top ends of the L-shaped sliding plates 166 penetrate to the lower part inside the sliding groove 1. The top of the L-shaped sliding plate 166 is of an arc structure. The bottom end of the L-shaped sliding plate 166 penetrates to the bottom of the filter screen plate 15 and is fixedly connected with a knocking block 167. A sliding groove 2 axially-through is formed in the middle of the L-shaped sliding plate 166. A limiting sliding plate 168 is slidably connected inside the sliding groove 2. The limiting sliding plate 168 is fixedly connected inside the connecting frame 161. A top spring 169 is fixedly connected to the top of the limiting sliding plate 168. The top end of the top spring 169 is fixedly connected to the upper surface of the inner wall of the sliding groove 2;

[0028] When filtering limestone through the filter screen plate 15, by starting the second motor 162, the transmission screw 163 can be rotated, and the threaded slider 164 can be driven to slide inside the sliding groove 1, so that the sliding scraper 165 can be driven to slide on the top of the filter screen plate 15, thereby scraping the filtered limestone. At the same time, the sliding of the sliding scraper 165 will also squeeze the L-shaped sliding plate 166, causing the L-shaped sliding plate 166 to slide downward. When the sliding scraper 165 slides off the top of the L-shaped sliding plate 166, under the pushing of the top spring 169, the L-shaped sliding plate 166 can be reset, and the knocking block 167 can be made to knock on the filter screen plate 15, thereby shaking off the filtered limestone and preventing the limestone from clogging inside the filter screen plate 15, ensuring the normal use of the crushing equipment.

[0029] As Figure 5 As shown in the figure, the utility model provides a limestone crushing device. The lifting mechanism 5 includes a connecting housing 51, which is fixedly connected to the top of the crushing equipment body 1. Three driving wheels 52 are movably connected inside the connecting housing 51. An intermediate wheel 53 is meshed and connected to the outer surfaces of two adjacent driving wheels 52. A third motor 54 is fixedly connected to the top of the connecting housing 51. The output shaft of the third motor 54 is fixedly connected to the top of the middle driving wheel 52. A spiral lifting rod 55 is fixedly connected to the bottom of the driving wheel 52. The bottom end of the spiral lifting rod 55 penetrates to the inside of the material lifting groove 17;

[0030] The incompletely crushed limestone will fall into the lifting hopper 17. By starting the third motor 54, the middle driving wheel 52 can be driven to rotate. Under the transmission of the middle wheel 53, the three driving wheels 52 can drive the three spiral lifting rods 55 to rotate simultaneously, facilitating the lifting of the incompletely crushed limestone, so that secondary crushing can be carried out.

[0031] Next, the working principle of the limestone crushing device will be specifically described.

[0032] As Figure 1-5 shown, when the limestone is crushed, the limestone to be crushed is sent into the falling chute 11 through the feed hopper 4. By starting the first motor 13, the driving wheel 12 can drive the crushing roller 14 to crush the limestone. The crushed limestone will fall on the filter mesh plate 15 for filtration. By starting the second motor 162, the transmission screw 163 can drive the threaded slider 164 to slide, so as to drive the sliding scraper 165 to slide on the top of the filter mesh plate 15, thereby scraping the filtered limestone, making the larger-sized limestone fall into the inside of the lifting hopper 17. By starting the third motor 54, the driving wheel 52 can be driven to rotate, so that the larger-sized limestone can be lifted by the spiral lifting rod 55, making the limestone fall from the material guiding chute 18, and then the limestone is secondarily crushed by the crushing roller 14, making the crushing effect of the limestone better. The larger-sized limestone will pass through the filter mesh plate 15 and fall into the collection box 3 in the placement bin 2, completing the crushing process of the limestone.

[0033] The above text generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
