Description

Technical Field

[0001] This utility model belongs to the field of feed production technology, and in particular relates to a grinding device for feed production. Background Technology

[0002] Feed is a general term for the food of artificially raised animals. In a narrow sense, it refers to the feed for livestock and poultry in agriculture and animal husbandry. Raw materials include more than ten categories such as soybeans, corn, meat and bone meal, and additives. In production, grinding equipment is needed to crush the raw materials to improve digestibility and processing quality, and to produce high-quality feed. Feed grinding is a key process to improve the comprehensive utilization efficiency of feed. By breaking down plant cell walls and increasing surface area, it significantly improves the digestibility of nutrients such as starch and protein for animals. At the same time, the fine texture improves palatability and stimulates feeding. The uniform powder structure is more conducive to the precise mixing of various raw materials, avoiding nutritional imbalances, and providing ideal raw materials for subsequent pelleting or extrusion processing, ensuring stable pellet quality and reducing waste.

[0003] In the feed production process, it is necessary to grind the relevant raw materials in order to carry out the mixing work smoothly. However, during the grinding process, some raw materials are prone to clump together under pressure and stick to the grinding plate, which requires manual cleaning. Manual cleaning is time-consuming and labor-intensive. Moreover, during the screening process, it is necessary to break up the clumps of raw materials, which can easily clog the mesh and affect the screening efficiency. Utility Model Content

[0006] The present invention is further configured as follows: a support frame for supporting the grinding box is fixedly connected to the bottom of the grinding box; a screening assembly is provided inside the support frame; the screening assembly includes a screening drum; a support ring is rotatably connected to the circumferential side of the screening drum; the outer wall of the support ring is fixedly connected to the inner wall of the support frame; a rotating seat is fixedly connected to the outer wall of the support ring; a guide plate is provided below the screening drum; the guide plate is fixedly connected to the inner wall of the support frame; a fixed inclined plate is fixedly connected to one side of the support frame; a second servo motor is installed at the bottom of the fixed inclined plate; the output shaft of the second servo motor is fixedly connected to the screening drum; a drive sprocket is fixedly connected to the output shaft of the second servo motor; a brush rod is rotatably connected between the fixed inclined plate and the rotating seat; a driven sprocket is fixedly connected to the brush rod; and the drive sprocket and the driven sprocket are connected by a chain.

[0007] The present invention is further configured such that: a third servo motor is installed on the outer wall of the grinding box, the output end of the third servo motor is fixedly connected to the corresponding first lead screw, a plurality of guide rods are fixedly connected to the outer wall of the grinding box, the guide rods are equally arranged on both sides of the grinding box, a V-shaped grinding plate is fixedly connected to the inner wall of the grinding box, a shuttle-shaped rolling roller is rolled on the top of the V-shaped grinding plate, the guide rods are slidably connected to the openings inside the support plate, a limit plate is fixedly connected to the bottom of the support plate, and the limit plate is slidably connected to the grinding box.

[0008] The present invention is further configured such that: an electric push rod is installed at the bottom of the support frame, a double U-shaped connecting hook is fixedly connected to the output end of the electric push rod, a material collection box is fixedly connected to the side of the double U-shaped connecting hook opposite to the electric push rod, the material collection box is placed at the bottom of the support frame, and a discharge port is opened on the circumferential side of the screening drum.

[0009] The present invention is further configured such that: a trapezoidal bucket is fixedly connected to the bottom opening of the grinding box, a bent pipe is fixedly connected to the bottom of the trapezoidal bucket, the bent pipe extends into the inside of the screening drum, a traveling gear is fixedly connected to the peripheral side of the shuttle-shaped pressing roller near the support plate, a fixed rack is meshed below the traveling gear, and the fixed rack is fixedly connected to the outer wall of the grinding box.

[0010] The present invention is further configured such that: an annular cavity is provided inside the feed hopper; the material blocking plate is rotatably engaged with the annular cavity to control the quantitative discharge of raw materials; a guide pipe is fixedly connected to the opening at the bottom of the annular cavity; a discharge port is provided at the bottom end of the guide pipe; and the discharge port and the scraper are respectively provided on opposite sides of the shuttle-shaped rolling roller.

[0011] This utility model has the following beneficial effects: 1. This utility model starts the first servo motor, which controls the rotation of the material blocking plate through gear transmission to adjust the discharge speed. At the same time, it drives the scraper to lift to avoid interfering with the grinding. After the raw material falls, the shuttle-shaped crushing roller moves and rotates with the grinding mechanism to crush the material until the raw material covers the V-shaped grinding plate. Then, the material blocking plate and scraper are adjusted to a non-fully reset state. The third servo motor drives the grinding mechanism to reciprocate and crush the material. After crushing, the material blocking plate and scraper are fully reset. The scraper scrapes the raw material into the trapezoidal hopper and enters the screening drum through the curved pipe. This setting can lift the scraper to avoid interfering with the grinding during the discharge and grinding process. During the reciprocating grinding process, it can block the material while avoiding the scraper resetting to interfere with the grinding. When scraping is needed, no material will be discharged and the scraper will reset. The grinding mechanism can then move to scrape the ground raw material into the screening component. It can also scrape off some of the raw material that has hardened on the V-shaped grinding plate to prevent it from affecting the next grinding, thereby improving the grinding efficiency.

[0012] 2. This utility model uses a second servo motor to drive the screening drum to reciprocate, causing the clumped raw material to disperse. The powdery raw material falls into the collection box. Once the collection box is full, the electric push rod pushes it out through the double U-shaped connecting hook and replaces it. The second servo motor continues to drive the screening drum to rotate circumferentially, and large particles of raw material are poured out from the discharge port. At the same time, the sprocket and chain drive drive the brush rod to clean the screening drum. This design can disperse the clumped raw material, which is beneficial for screening. The screening and cleaning of the screening drum can be completed by a single second servo motor, which can significantly improve the screening efficiency.

[0024] In this embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the feed hopper 301 has an annular cavity 304 inside. The baffle plate 302 rotates with the annular cavity 304 to control the quantitative discharge of raw materials. The discharge speed can be controlled by adjusting the rotation angle. A guide pipe 305 is fixedly connected to the opening at the bottom of the annular cavity 304. The bottom end of the guide pipe 305 is provided with a discharge port 306. The discharge port 306 and the scraper plate 406 are respectively provided on opposite sides of the shuttle-shaped rolling roller 202.

[0025] The working principle of this embodiment is as follows: During operation, the raw material is first poured into the feed hopper 301, then the third servo motor 102 is started. The third servo motor 102 rotates synchronously and drives the corresponding first lead screw 101 to rotate. The support plate 201 is provided with threaded holes 203, which are threadedly connected to the corresponding first lead screw 101, thereby driving the grinding mechanism 2 to move to the edge of the shuttle-shaped grinding roller 202 facing the V-shaped grinding plate 104. The material blocking plate 302 is placed horizontally, and the scraper plate 406 is placed vertically. This is the initial state. Then the first servo motor 204 is started. The first servo motor 204 simultaneously drives the second bevel gear 401 and the second lead screw 402 to rotate. Because the second bevel gear 401 meshes with the first bevel gear 303, the material blocking plate... The extended end of 302 passes through the feed hopper 301 and the support plate 201 and is fixedly connected to the first bevel gear 303. Therefore, the second bevel gear 401 rotates and drives the material blocking plate 302 to rotate in the annular cavity 304. The speed of material discharge can be controlled by adjusting the rotation angle. The second lead screw 402 and the threaded seat 403 are threadedly connected. The bottom of the threaded seat 403 is hinged to a pull rod 404, and the pull rod 404 is hinged to a hinge rod 405. The hinge rod 405 is fixedly connected to a scraper 406. The rotation of the second lead screw 402 drives the threaded seat 403 to move, thereby driving the pull rod 404 and the hinge rod 405 to rotate, thereby raising the bottom of the scraper 406 by a certain angle, so that the scraper 406 will not interfere with the grinding process during the reciprocating grinding process. The shuttle-shaped pressing roller 2 A traveling gear 205 is fixedly connected to the peripheral side of the support plate 201. A fixed rack 105 is fixedly connected to the outer wall of the grinding box 1. The traveling gear 205 and the fixed rack 105 mesh. As the raw material falls from the outlet, the third servo motor 102 is started, driving the grinding mechanism 2 to move, thereby driving the shuttle-shaped crushing roller 202 to rotate. After the raw material falls, the shuttle-shaped crushing roller 202 crushes the raw material. The grinding mechanism 2 moves to the end so that the raw material fills the V-shaped grinding plate 104. At this time, the first servo motor 204 is started again, causing the blocking plate 302 to rotate until the raw material is just blocked. The lifting angle of the scraper 406 decreases. At this time, the blocking plate 302 and the scraper 406 are not completely reset. At this time, no material is discharged from the outlet 306. The material plate 406 does not scrape the material. The third servo motor 102 rotates forward and backward, causing the grinding mechanism 2 to reciprocate and grind the material. After grinding is completed, the first servo motor 204 is started again, causing the material blocking plate 302 and the scraper plate 406 to reset. The bottom of the scraper plate 406 is in contact with the V-shaped grinding plate 104. The grinding mechanism 2 continues to move, causing the scraper plate 406 to scrape the raw material into the trapezoidal hopper 10. The raw material enters the screening drum 501 along the curved pipe 11. The grinding operation is repeated. Then, the second servo motor 506 is started. The second servo motor 506 rotates forward and backward, driving the screening drum 501 to rotate back and forth within a certain angle range. The ground raw material swings inside the screening drum 501, causing the clumps of raw material to disperse. Under the action of the guide plate 504, the material is ground.Powdered raw materials fall into the collection box 9 below. The screening roller 501 continues to operate. When the collection box 9 is full of powder, the grinding mechanism 2 stops running, and the second servo motor 506 is turned off. Then, the electric push rod 7 starts to push out the collection box 9. The electric push rod 7 and the collection box 9 are connected by a double U-shaped hook 8, which is easy to install and remove. After installing a new collection box 9, the electric push rod 7 retracts to return the collection box 9 to its original position. Then, the second servo motor 506 is started again. At this time, the second servo motor 506 drives the screening roller 501 to rotate in a circular motion, so that the discharge port 511 is aligned with the opening of the collection box 9, and the large particles of raw materials that have not been screened out are discharged from the discharge port 511. The material is poured out because a drive sprocket 507 is fixedly connected to the output shaft of the second servo motor 506, and a driven sprocket 509 is fixedly connected to the brush rod 508. The drive sprocket 507 and the driven sprocket 509 are connected by a chain 510. Therefore, while the screening drum 501 rotates, it drives the brush rod 508 to rotate. The bristles on the brush rod 508 clean the screening drum 501, preventing blockage and improving screening efficiency, until all large particles of raw material in the screening drum 501 are poured out. Then, the electric push rod 7 is activated to push out the collection box 9, replace it with a powder collection box 9, and continue to start the grinding mechanism 2. This process is repeated.
