DETAILED DESCRIPTION

[0023] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a grinding device with a multi-stage grinding function, including a body 1, the top surface of the body 1 is fixedly connected to a chassis 3, the surface of the body 1 is fixedly connected to a bracket 4, the top surface of the body 1 passes through and is fixedly connected to a feed port 5, and a grinding part 2 is arranged inside the body 1, and the grinding part 2 includes: a motor 21, a rotating shaft 22, a grinding knife 23, a first screen 24, grinding balls 25, a connecting rod 26, an insert rod 27, a linkage block 28, a spring 29, a guide groove 210, a limit frame 211, a second screen 212, a cross bar 213, a vertical groove 215, and an inclined groove 216.

[0024] The motor 21 is fixedly connected to the inner wall of the chassis 3, and the output shaft of the motor 21 is fixedly connected to the rotating shaft 22, which penetrates the body 1 and is rotatably connected. The surface of the rotating shaft 22 is fixedly connected to the grinding knife 23. The raw walnuts to be used for walnut oil production are poured into the body 1 through the feed port 5, and the motor 21 is started. The output shaft of the motor 21 will drive the grinding knife 23 to rotate during the rotation process, and the grinding knife 23 will perform preliminary cutting and grinding on the walnut raw materials during the rotation. The first screen 24 is penetrated by the rotating shaft 22, and the rotating shaft 22 penetrates and is fixedly connected with the grinding ball 25. In the preliminary grinding stage, the relatively fine walnut raw materials will fall through the first screen 24, and will slide along the surface of the grinding ball 25 to the bottom of the grinding ball 25, and the grinding ball 25 will be driven to rotate by the rotating shaft 22. During the rotation of the grinding ball 25, the walnut raw material will be squeezed between the grinding ball 25 and the inner wall of the body 1 for grinding. The surface of the grinding ball 25 is fixedly connected with a connecting rod 26. The bottom end of the insertion rod 27 passes through the top surface of the connecting rod 26 and is slidably connected. The top surface of the insertion rod 27 is fixedly connected with a linkage block 28. In the initial grinding stage, the grinding knife 23 cuts and grinds larger walnut raw materials that cannot pass through the first screen 24. During the rotation of the grinding ball 25, the connecting rod 26 will be driven to rotate together, and the connecting rod 26 will drive the linkage block 28 to rotate together with the center of the rotating shaft 22 as the axis through the insertion rod 27. A guide groove 210 is opened on the inner wall of the body 1. The linkage block 28 passes through the guide groove 210 and is slidably connected. The top surface of the linkage block 28 is fixedly connected to the bottom surface of the first screen 24. A spring 29 is fixedly connected to the bottom surface of the linkage block 28. During the rotation process, the linkage block 28 will first slide along the guide groove 210. After sliding a certain distance along the guide groove 210, the linkage block 28 will enter the inclined groove 215, causing the linkage block 28 to contact the inclined surface of the inclined groove 215, forcing the linkage block 28 to contact and push the insertion rod 27 to insert into the interior of the connecting rod 26, and causing the spring 29 to be compressed. The bottom surface of the spring 29 is fixedly connected to the top surface of the connecting rod 26. The inner wall of the machine body 1 is also provided with an inclined slot 216 and a vertical slot 215. When the linkage block 28 continues to slide, it will move to the position of the vertical slot 216. The width of the vertical slot 216 is wider than the inclined slot 215 and the guide slot 210. When the linkage block 28 enters the vertical slot 216, the compressed spring 29 will lift the linkage block 28, so that the linkage block 28 lifts the first screen 24, thereby causing the first screen 24 to generate an upward impact force. The guide slot 210 is connected with the inclined slot 216 and the vertical slot 215. The inner side of the machine body 1 is fixedly connected to the limit frame 211, and the rotating shaft 22 passes through the limit frame 211 and is rotatably connected. The inner side of the machine body 1 is fixedly connected to the second screen 212, and the surface of the rotating shaft 22 is fixedly connected to the cross bar 213.The bottom surface of the cross bar 213 is connected with a scraper bar 214, and the bottom surface of the scraper bar 214 is in contact with the surface of the second screen 212. When the grinding balls 25 grind the walnut raw materials in the second stage, the ground raw materials will fall onto the surface of the second screen 212, and the rotating shaft 22 will drive the scraper bar 214 to rotate through the cross bar 213 during the rotation process, and the scraper bar 214 will scrape the second screen 212. There are two groups of connecting rods 26, and the two groups of connecting rods 26 are symmetrically arranged with the center line of the grinding balls 25 as the symmetry axis.

[0025] Based on the above embodiment, the raw walnuts to be used for walnut oil production are poured into the machine body 1 through the feed port 5, and the motor 21 is started. The output shaft of the motor 21 drives the grinding knife 23 to rotate during the rotation process, and the grinding knife 23 performs preliminary cutting and grinding on the walnut raw materials during the rotation. In the preliminary grinding stage, the relatively fine walnut raw materials will fall through the first screen 24, and will slide along the surface of the grinding balls 25 to the bottom of the grinding balls 25, and the grinding balls 25 are driven to rotate by the rotating shaft 22. During the rotation process, the grinding balls 25 will squeeze the walnut raw materials between the grinding balls 25 and the inner wall of the machine body 1 for grinding, and finally fall to the surface of the second screen 212. In the preliminary grinding stage, the larger walnut raw materials cut and ground by the grinding knife 23 cannot pass through the first screen 24. During the rotation process of the grinding balls 25, the connecting rod 26 is driven to rotate together, and the connecting rod 26 drives the linkage block 28 to rotate together with the center of the rotating shaft 22 as the axis through the insertion rod 27. When the linkage block 28 continues to slide, it will move to the position of the vertical groove 216, and the width of the vertical groove 216 is wider than the inclined groove 215 and the guide groove 210. When the linkage block 28 enters the vertical groove 216, the compressed spring 29 will lift the linkage block 28, so that the linkage block 28 lifts the first screen 24, thereby generating an upward impact force on the first screen 24, forcing the larger walnut raw materials on the surface of the first screen 24 to bounce up and be ground by the grinding knife 23 again, so as to prevent some raw materials from being unable to enter the next grinding stage due to the initial grinding stage. The multi-stage grinding can promote the grinding efficiency and prevent the first screen 24 from being blocked.

[0026] When the grinding balls 25 perform the second stage grinding of the walnut raw materials, the ground raw materials will fall onto the surface of the second screen 212, and the rotating shaft 22 will drive the scraper bar 214 to rotate through the cross bar 213 during the rotation process, and the scraper bar 214 will scrape the second screen 212 to prevent the second screen 212 from being blocked and keep the discharge smooth.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
