[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4 In this embodiment, a pig feed crushing device includes a box body 1, a feed hopper 2 is fixed to the box body 1, and two crushing rollers 13 and two grinding rollers 14 are rotatably connected to the inside, and the rotating shaft ends of the crushing rollers 13 and the grinding rollers 14 are fixed with mutually meshing gears 17, and a side cover 3 is fixed on the left side of the box body 1 to cover the rotating shaft end and the gear 17, and a motor 4 for driving the second grinding roller 14 to rotate is installed on the left side of the side cover 3. A guide portion is installed inside the box body 1 and an anti-blocking portion is installed on the outside of the box body that extends to the inside of the feed hopper 2.

[0020] In the above structure, when one of the grinding rollers is driven to rotate by the motor, the meshing relationship between the gears can simultaneously make the two crushing rollers rotate relative to each other, and the two grinding rollers rotate relative to each other. Therefore, the feed to be crushed is placed in the feed hopper, and the feed is of different sizes. While falling, the anti-blocking part runs to prevent the feed from being blocked in the feed hopper and affecting the feeding. At the same time, the guide part can first guide the feed to the two crushing rollers to complete the rough processing, and then the lower part is collected after falling, and then introduced into the feed hopper. The feed that can fall is guided to the two grinding rollers through the operation of the guide part to complete the processing of the feed, thereby improving the processing quality, making the feed of the same size, reducing the labor workload and making the processing more meticulous to improve the digestion of piglets.

[0021] Wherein 2 is the direction shown, the guide part includes an inclined plate 5, a baffle 6, two upper scrapers 7 fixed on the inner side of the box body 1, and an upper guide plate 8 located between the two upper scrapers 7, and two side stops 15 fixed on the front and rear side walls. The two side stops 15 opposite to each other on the left side are located above the gap between the two grinding rollers 14, and the two side stops 15 opposite to each other on the right side are located above the gap between the two crushing rollers 13. The inclined plate 5 is located below the feed hopper 2 and tilted toward the lower right. The upper guide plate 8 is in a V shape with the opening facing downward, and the bottom of the upper guide plate 8 is respectively in contact with the crushing roller 13 and the grinding roller 14 located in the middle, and the bottom of the two upper scrapers 7 is in contact with the grinding roller 14 on the leftmost side and the crushing roller 13 on the rightmost side. The inner side of the box body 1 is rotatably connected to a rotating rod 27 located above the upper guide plate 8, and a blocking plate 29 that can be in contact with the inclined plate 5 and the baffle 6 is fixed to the outside of the rotating rod 27. A handle 28 is fixed to one end of the rotating rod 27 located outside the box body 1. Therefore, when the feed is introduced into the feed hopper, the handle is first used to rotate the rotating rod to drive the blocking plate and the inclined plate to stick to each other. The inclined plate then guides the feed through the blocking plate and the upper guide plate to the space between the two crushing rollers for crushing. At the same time, under the action of the side guard, the falling feed can be guided to the gap between the crushing roller and the grinding roller.

[0022] Then the crushed feed is introduced into the feed hopper again. Before that, the handle is used to rotate the rotating rod, which drives the baffle plate to stick to the baffle plate, so that the inclined plate guides the feed. Under the guidance of the baffle plate and the upper guide plate, the feed can be introduced into the space between the two grinding wheels to complete the grinding and refining process.

[0023] In addition, if Figure 4 In the direction shown, the anti-blocking part includes two movable holes on the feed hopper, with a sieve plate 25 movably connected between the two movable holes. A connecting plate 24 is fixed to one side of the sieve plate 25 and penetrates one of the movable holes. By moving the connecting plate, the sieve plate moves in the feed hopper, thereby moving the feed inside, so as to prevent the feed from blocking the bottom of the feed hopper and affecting the discharge of the feed.

[0024] Furthermore, a fixed plate 21 is installed on the top of the side cover 3, and two sleeves 22 are installed on the fixed plate 21. A movable plate 19 that is installed on the side cover 3 is sleeved between the two sleeves 22. The movable plate 19 is fixedly connected to the connecting plate 24. The outer sides of the two sleeves 22 are sleeved with a spring 23 located between the movable plate 19 and the fixed plate 21. By moving the movable plate, the movable plate presses the spring and simultaneously moves the connecting plate. When the movable plate is released, the elastic force of the spring can be used to reset the movable plate, driving the screen plate to reset. At the same time, the screen plate can also be moved by moving the movable plate, thereby improving the anti-smear effect.

[0025] Furthermore, an eccentric wheel 18 is fixed to the shaft end of the second grinding roller 14, and the bottom of the movable plate 19 is rotatably connected to a roller 20 that is attached to the side of the eccentric wheel 18. When the motor drives one of the grinding rollers to rotate, the eccentric wheel rotates at the same time. When the eccentric wheel rotates, the roller also rotates. When the eccentric part passes through the roller, it can lift the movable plate to press the spring, and at the same time, the screen plate is moved by the connecting plate. Then, with the cooperation of the spring, the movable plate is driven to reset. Under this cycle, the feed in the feed hopper can be continuously moved to prevent blockage when falling.

[0026] At the same time, an adjustment plate 26 is fixed to the sieve plate 25 by screws, and a waist hole is opened on the adjustment plate 26. Through the waist hole of the adjustment plate, the position can be adjusted on the sieve plate, thereby adjusting the opening size of the feed hopper discharge port, which is convenient for adjusting and discharging according to needs.

[0027] Among them Figure 2 In the direction shown, two lower scrapers 10 are fixed to the inside of the box body 1, located below the crushing roller 13 and the grinding roller 14, and a lower guide plate 12 is fixed between the two lower scrapers 10. The top of the left lower scraper 10 is in contact with the bottom of the leftmost grinding roller 14, and the top of the right lower scraper 10 is in contact with the rightmost crushing roller 13. The top of the lower guide plate 12 extends into the gap between the grinding roller 14 and the crushing roller 13, and the top of the lower guide plate 12 is in contact with and fits with the crushing roller 13. The cooperation between the two lower scrapers and the lower guide plate can form two unloading areas at the bottom of the box body, realizing separate unloading of crushed and ground materials for convenient collection.

[0028] The working principle of the above embodiment is:

[0029] By introducing the feed into the feed hopper, the motor runs, driving the grinding roller to rotate, and also driving the eccentric wheel and gear to rotate. Under the meshing of the gears, the crushing roller and the grinding roller can rotate relative to each other. The eccentric wheel pushes the movable plate through the roller and squeezes the spring. At the same time, the connecting plate drives the screen plate to move in the feed hopper, thereby moving the feed at the bottom to prevent it from being blocked at the discharge port of the feed hopper. The feed slides down through the inclined plate, and then is guided by the baffle plate and the upper guide plate. The feed will fall into the two crushing rollers to complete the crushing process. The crushed feed will be guided and collected by the lower guide plate and the lower scraper. When the feed in the feed hopper is processed, the feed is introduced into the feed hopper again, and the rotating rod is turned by the handle. The rotating rod drives the baffle plate to stick to the baffle. Therefore, under the guidance of the inclined plate, the feed falls and cooperates with the baffle plate and the upper guide plate to guide the crushed feed to the space between the two grinding rollers for fine grinding, and then is collected again by the lower scraper and the lower guide plate.

[0030] In summary, the feed can be broken into smaller pieces, which improves digestibility, reduces manual labor, and improves efficiency.
