AI Technical Summary
Existing stone crushing equipment has the problem that some larger stones are not completely crushed during the crushing process, resulting in inconsistent stone sizes and affecting the crushing effect.
The design employs a spherical crushing chamber and a grinding box. The crushing roller shaft inside the spherical crushing chamber rotates at high speed, and the impact of the arc-shaped crushing blades achieves multiple crushing of the stone. Then, in the grinding box, the stone is ground into powder through the friction of the grinding piles.
It enables rapid crushing and further grinding of larger stones, ensuring uniform size of finished stone products and improving crushing efficiency and product quality.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] Embodiment 1, as Figure 1-Figure 3 As shown, a stone crushing device can automatically crush larger stones into powdered stones that are easy to process. Before use, the stone raw materials are put into the connecting pipe 11 inside the crushing box 1 through the feeding funnel 5. A feeding pipe 6 is connected between the feeding funnel 5 and the connecting pipe 11, which can directly feed the connecting pipe 11. The stones fall into the crushing spherical bin 14 at the bottom through the connecting pipe 11. The device can be started to crush. The first motor 12 is connected to the driving shaft 16, and the driving shaft 16 can drive the crushing rod shaft 20 inside the crushing spherical bin 14 to move forward. The arc-shaped crushing knife 19 connected to the outer wall of the crushing rod shaft 20 also rotates synchronously, and the stone is crushed inside the spherical bin 14 and collides with the crushing rod shaft 20, so that the stone material is swung in the crushing spherical bin 14. During the swinging process, the stone will collide with the arc-shaped crushing knife 19, and the arc-shaped crushing knife 19 will hit the stone to the inner wall of the crushing spherical bin 14, and the stones will collide with each other, thereby realizing the rapid crushing of larger stones. The crushed gravel is input into the grinding box 2 through the discharge port 15 at the bottom for the next processing step.
[0023] Embodiment 2, as Figure 1-Figure 4As shown, a stone crushing device, when the stone falls into the grinding box, the crushed stone can be further ground and processed, two groups of No. 2 motors 21 drive two groups of grinding piles 22 to rotate through the rotating shaft 23, and the mutual friction between the grinding piles 22 can make the stone be ground into a powder state of composite processing standards, and the crushed stone falls into the lower hopper 3, and the finished product of suitable size is filtered out by the filter plate 24, and then transported to the outside of the hopper through the discharge chute 8, thereby completing the processing process, and the crushing and filtering make the size standard of the stone uniform, so that the quality of the finished product is higher.
[0024] How it works
[0025] It should be noted that the utility model is a stone crushing device. When in use, stone raw materials are put into the connecting pipe 11 inside the crushing box 1 through the feeding funnel 5. A feeding pipe 6 is connected between the feeding funnel 5 and the connecting pipe 11, which can directly feed the connecting pipe 11. The stones fall into the crushing spherical bin 14 at the bottom through the connecting pipe 11. The device is started to perform crushing work. The No. 1 motor 12 is connected to the driving shaft 16. The driving shaft 16 can drive the crushing rod shaft 20 inside the crushing spherical bin 14 to rotate. At the same time, the arc-shaped crushing knife 19 connected to the outer wall of the crushing rod shaft 20 also rotates synchronously. The stones are crushed inside the spherical bin 14 and collide with the crushing rod shaft 20, so that the stone materials are crushed. The stones are swung in the crushing spherical bin 14. During the swinging process, the stones will collide with the arc-shaped crushing knife 19. The arc-shaped crushing knife 19 will hit the stones against the inner wall of the crushing spherical bin 14, and the stones will collide with each other, thereby achieving rapid crushing of larger stones. The crushed stones are input into the grinding box 2 through the discharge port 15 at the bottom. When the stones fall into the grinding box, the two groups of No. 2 motors 21 drive the two groups of grinding piles 22 to rotate through the rotating shaft 23. Through the mutual friction between the grinding piles 22, the stones can be ground into a powder state of composite processing standards. The crushed stones fall into the lower bin 3, and the finished products of suitable size are filtered out through the filter plate 24, and then transported out of the bin through the discharge chute 8, thereby completing the processing process.
