[0024] See also Figure 1-6As shown, a closed grinder for pig feed processing includes a bottom plate 1; a fixing sleeve 2 for supporting an outer casing 3 is installed on the bottom plate 1, and a No. 1 limiting ring 4 is installed in the openings on both sides of the outer casing 3, an inner cylinder 5 is provided in the outer casing 3, and the two ends of the inner cylinder 5 are passed through and arranged in the two No. 1 limiting rings 4, and the two ends of the inner cylinder 5 are respectively installed with No. 2 limiting rings 6, and the two No. 2 limiting rings 6 are located outside the two No. 1 limiting rings 4, and the inner cylinder 5 is evenly distributed with sieve holes 7, and the sieve holes 7 are located in the outer casing 3;

[0025] A closing plate 8 is provided at the opening at one end of the inner cylinder 5. A hole is formed through the side of the closing plate 8. A rotating shaft 9 is provided through the hole. Crushing blades 10 are evenly distributed and installed on one end of the rotating shaft 9 located inside the inner cylinder 5. Fixed plates 11 are longitudinally arranged on the inner wall of the inner cylinder 5, and the crushing blades 10 are cross-arranged in the gaps between the fixed plates 11.

[0026] A feed pipe 13 is provided at the end of the inner cylinder 5 opposite to the closing plate 8, a support ring 14 for supporting the feed pipe 15 is installed on the bottom plate 1, and the bottom end port of the feed pipe 15 is located in the feed pipe 13, and a drive component for driving the inner cylinder 5 is provided on the bottom plate 1.

[0027] During operation, the existing closed crusher has poor crushing effect and cannot ensure the consistency of crushed particle size, resulting in uneven crushing and poor crushing effect, which affects the ratio mixing effect. In this solution, the raw material is fed into the feeding pipe 13 from the feeding pipe 15, and then the feed enters the inner cylinder 5 through the feeding pipe 13. At this time, the No. 1 motor 24 is controlled to operate. When the No. 1 motor 24 operates, it drives the rotating shaft 9 to rotate, and when the rotating shaft 9 rotates, it drives the crushing blade 10 to rotate in the inner cylinder 5 to crush the raw material, and when the crushing blade 10 rotates, it will rotate between the gaps of the fixed plate 11, and at the same time, the driving component drives the inner cylinder 5 to rotate. When the inner cylinder 5 rotates, it will rotate in the outer casing 3, and the inner cylinder 5 is limited and fixed under the limitation of the two No. 2 limit rings 6 and the two No. 1 limit rings 4 to prevent the inner cylinder 5 from escaping from the outer casing 3 when it rotates. At this time, when the inner cylinder 5 rotates, it will drive the fixed plate 11 to rotate around the rotating shaft 9, and When the V-shaped scraper 12 is scraped on the inner surface of the outer casing 3, the raw material debris on the inner wall of the outer casing 3 will be concentrated in the opening groove of the V-shaped scraper 12. When the V-shaped scraper 12 drives the concentrated raw material to move to the bottom discharge port, the raw material debris will fall into the discharge port and remain on the sealing plate 23. Raw material that does not meet the particle size will continue to remain in the inner cylinder 5 for crushing, and raw material that meets the particle size will be continuously discharged from the sieve hole 7. After the crushing is completed, the sealing plate 23 is removed from the sealing block 22 for discharge. The combination achieves the effect of uniform crushing, effectively ensures the consistency of the crushed particle size, and has a better crushing effect than the traditional closed crusher.

[0028] The center lines of the rotating shaft 9, the inner tube 5, and the outer casing 3 all coincide with each other. The inner tube 5 is evenly arranged with V-shaped scrapers 12, and the V-shaped scrapers 12 are located in the fixed sleeve 2. The end of the rotating shaft 9 located outside the inner tube 5 is installed with a No. 1 motor 24, and the No. 1 motor 24 is installed on the base plate 1 through a fixing part.

[0029] See also Figure 1-6 As shown, the drive assembly includes two hollow shafts 16 and two gear rings 19. The two hollow shafts 16 are symmetrically mounted on both sides of the base plate 1 through a bracket, and the two gear rings 19 are symmetrically mounted on both ends of the inner cylinder 5. A rotating shaft 17 is rotatably mounted in the two hollow shafts 16, and gears 18 are respectively mounted at both ends of the two rotating shafts 17. The four gears 18 are symmetrically arranged on both sides of the two gear rings 19, and the four gears 18 are respectively engaged with the two gear rings 19.

[0030] During operation, in order to ensure the normal use of the crusher in this scheme and improve the crushing effect, in this scheme, by controlling the operation of the No. 2 motor 25, the No. 2 motor 25 will drive one of the rotating shafts 17 to rotate, and when one of the rotating shafts 17 rotates, it will drive the two gears 18 on it to rotate, and when the two gears 18 rotate, they will drive the inner tube 5 to rotate in the outer casing 3 through the gear ring 19, and when the gear 18 rotates, it will drive the two gears 18 on the other side to rotate, and the driving effect is achieved by cooperation, ensuring the normal driving use of the crusher and ensuring the stability of use.

[0031] The hollow shaft 16 is parallel to the center line of the outer casing 3, and a second motor 25 is installed at the end of one of the rotating shafts 17, and the second motor 25 is installed on the base plate 1 through a fixing member. The two gear rings 19 are located outside the two second limit rings 6.

[0032] A side plate 20 is installed outside the opening of the inner cylinder 5 opposite to the feed pipe 13. Holes are evenly distributed through the sides of the side plate 20 and the closing plate 8, and bolts 21 for fastening the side plate 20 and the closing plate 8 are respectively penetrated through the corresponding holes.

[0033] A discharge port is provided under the outer casing 3 , and a sealing block 22 for sealing is installed under the discharge port. A sealing plate 23 for sealing the sealing block 22 is slidably provided in the sealing block 22 , and a sealing plug 26 for sealing is provided in the upper opening of the feeding pipe 15 .

[0034] Working principle: by feeding the raw material into the feed pipe 13 from the feeding pipe 15, the feed will then enter the inner cylinder 5 through the feed pipe 13. At this time, the No. 1 motor 24 is controlled to operate. When the No. 1 motor 24 operates, it will drive the rotating shaft 9 to rotate. When the rotating shaft 9 rotates, it will drive the crushing blade 10 to rotate in the inner cylinder 5 to crush the raw material. When the crushing blade 10 rotates, it will rotate between the gaps of the fixed plate 11. At the same time, the inner cylinder 5 is driven to rotate through the driving component. When the inner cylinder 5 rotates, it will rotate in the outer casing 3. The inner cylinder 5 is limited and fixed under the limitation of the two No. 2 limiting rings 6 and the two No. 1 limiting rings 4 to prevent the inner cylinder 5 from escaping from the outer casing 3 when it rotates. At this time, the inner cylinder 5 will drive the fixed plate 11 to rotate around the rotating shaft 9 when it rotates, and the fixed plate 11 will turn the raw materials in the inner cylinder 5 when it moves. During the turning process of the raw materials, the crushing operation of the crushing blade 10 is coordinated to evenly crush the raw materials. At this time, the raw material debris that meets the particle size will be discharged from the sieve hole 7 and remain in the outer casing 3, and the inner cylinder 5 rotates When the V-shaped scraper 12 is driven to scrape the inner surface of the outer casing 3, the raw material debris on the inner wall of the outer casing 3 will be concentrated in the open groove of the V-shaped scraper 12. When the V-shaped scraper 12 drives the concentrated raw material to move to the bottom discharge port, the raw material debris will fall into the discharge port and remain on the sealing plate 23, while the raw material that does not meet the particle size will continue to remain in the inner cylinder 5 for crushing, and the raw material that meets the particle size will be continuously discharged from the sieve hole 7. After the crushing is completed, the sealing plate 23 is taken out from the closed block 22 for discharge. When the No. 2 motor 25 is running, it will drive one of the rotating shafts 17 to rotate, and when one of the rotating shafts 17 rotates, it will drive the two gears 18 on it to rotate. When the two gears 18 rotate, they will drive the inner cylinder 5 to rotate in the outer casing 3 through the gear ring 19, and when the gear 18 rotates, it will drive the two gears 18 on the other side to rotate, so as to achieve the effect of uniform crushing, effectively ensure the consistency of the crushed particle size, and have better crushing effect than the traditional closed crusher.
