[0029] like Figure 1-Figure 10 As shown, a black pepper crushing and grinding device according to the present invention comprises an outer shell 1, a first servo motor 4 and a second servo motor 5 are fixedly mounted on the bottom of the outer shell 1 through a fixed frame, and output ends of the first servo motor 4 and the second servo motor 5 are respectively fixedly connected to a first rotating shaft 6 and a second rotating shaft 7 through couplings;

[0030] Several support plates 8 are staggered and fixedly connected at equal intervals inside the outer shell 1.

[0033] A feed sector tube 16 is movably connected to the top of the frustum slitting disk 13, a feed trough 17 is provided at the bottom of the feed sector tube 16, the height of the feed trough 17 is 2.5 mm, a cutting plate 18 is fixedly connected to the outer wall of one side of the feed sector tube 16, a cutting groove 19 is provided at the bottom of the other end of the cutting plate 18, the height of the cutting groove 19 is 2.5 mm, the inner wall of the cutting groove 19 is ground with an inclined cutting edge 20, a feed discharge trough 21 is provided at the inner bottom of the cutting plate 18, the feed discharge trough 21 is connected with the feed trough 17 and the cutting groove 19, one end of the cutting plate 18 away from the feed sector tube 16 is fixedly connected to a fixing frame 22, a plurality of scraper plates 23 are fixedly connected at equal intervals to the bottom of the fixing frame 22, and the scraper plates 23 are movably inserted in the annular groove 15.

[0034] A cover plate 2 is installed on the top of the outer shell 1, and one end of the feed fan-shaped tube 16 away from the frustum cutting disk 13 is fixed through the cover plate 2.

When the height of the feeding groove 21 is greater than the height of the cutting groove 19, the cutting edge 20 inside the cutting groove 19 can effectively discharge the complete black pepper particles in the ball groove 14 smoothly after cutting.

[0039] When in use, the black pepper to be ground is added to the feeding fan-shaped tube 16. The diameter of the black pepper particles inside the feeding fan-shaped tube 16 is 3.5 to 5 mm. The black pepper particles can fall into the ball groove 14 with a radius of 2.5 mm, and the ball groove 14 on the frustum cutting disk 13 below the feeding fan-shaped tube 16 is completely filled.

The black pepper grains will be cut when it touches the ball groove 14, and some of the cut black pepper grains will remain in the ball groove 14, and the cut black pepper grains will be discharged to the inside of the outer shell 1 along the discharge groove 21 with a height of 5 mm and fall onto the crushing fan blades 9 to be gradually crushed, and the black pepper grains inside the ball groove 14 will continue to rotate with the rotation of the frustum cutting disk 13. When the frustum cutting disk 13 rotates a certain angle, the scraper plate 23 arranged on the fixing frame 22 can scrape out the black pepper grains inside the ball groove 14, and the scraped black pepper grains will also fall into the inside of the outer shell 1 along the inclined surface of the frustum cutting disk 13 and fall onto the crushing fan blades 9 to be gradually crushed. Multiple groups of crushing fan blades 9 can crush the half-cut black pepper grains for multiple times, and finally the crushed black pepper grains will fall into the inside of the grinding chamber for sufficient crushing and grinding. After the grinding is completed, the sealing plate 26 can be opened to take out the crushed black pepper.
