With the vigorous development of the breeding industry and the continuous progress of the feed industry, the performance of the feed raw material grinding device is becoming increasingly demanding.

[0007] According to the above technical solution, the connecting shaft, the first rotating rod and the connecting frame are provided in two sets. The two sets of the connecting shaft, the first rotating rod and the connecting frame are symmetrically distributed on the left and right sides of the fixed ring, and the two sets of the connecting frames are rotatably connected to the inside of the T-shaped frame. By setting two sets, the T-shaped frame can drive the first gear, the second rotating rod and the grinding ball to perform circular motion.

[0008] According to the above technical solution, the second grinding assembly includes a second servo motor, which is fixedly connected to the top of the base plate. A first rotating shaft is fixedly connected to the top of the second servo motor. A composite pulley is fixedly connected to the periphery of the first rotating shaft. A first transmission belt is driven to the periphery of the composite pulley. A rotating disk is driven to the inner side of the first transmission belt. A pull ring is fixedly connected to the inner side of the rotating disk. A fixed column is fixedly connected inside the rotating disk. The fixed column is rotatably connected to the inside of the support platform. A rectangular frame is fixedly connected to the top of the fixed column.

[0009] According to the above technical solution, the top of the first rotating shaft is rotatably connected to the bottom of the support platform, the pull ring is rotatably connected to the bottom of the support platform, and the top of the one-way threaded rod is rotatably connected to the fixed column, so as to facilitate the movement of the limiting frame and the grinding bucket under the action of the one-way threaded rod.

[0010] According to the above technical solution, the limiting frame is slidably connected to the inside of the fixed column, and the protective sleeve is slidably connected to the inside of the grinding hopper. This facilitates the protection sleeve in preventing the feed material from entering the inside of the fixed column when the feed material in the guide hopper enters the grinding hopper and when the feed material in the grinding hopper is being discharged.

[0011] According to the above technical solution, the bottom of the grinding bucket is in contact with the top of the support base, and four support bases are provided. The four support bases are symmetrically distributed inside the protective box, so that when the limiting frame drives the grinding bucket down to a certain position, the support base can support the grinding bucket, so that the limiting frame can continue to drive the baffle to move for material feeding.

[0012] According to the above technical solution, the feeding mechanism includes a second transmission belt, which is driven to the periphery of the composite pulley. A pulley is driven to the inner side of the second transmission belt, and a drive shaft is fixedly connected inside the pulley. The drive shaft is rotatably connected to the support platform and the support frame. A first bevel gear is fixedly connected to the periphery of the drive shaft. A second bevel gear meshes with the top left side of the first bevel gear. A bidirectional threaded rod is fixedly connected inside the second bevel gear.

A sealing plate is fixedly connected to the inner side of the movable frame. The sealing plate is slidably connected inside the protective box and is located at the bottom of the grinding box.

[0013] According to the above technical solution, the movable frame and sealing plate are provided in two sets. The two sets of movable frames and sealing plates are symmetrically distributed around the bidirectional threaded rod, and the tops of the two sets of sealing plates are in contact with the bottom of the grinding box, so as to facilitate the sealing of the bottom of the grinding box under the action of the sealing plate.

[0014] According to the above technical solution, the limiting mechanism includes an L-shaped frame, which is fixedly connected to the rear side of the support platform. A cylinder is fixedly connected to the rear side of the L-shaped frame. An insert block is fixedly connected to the output end of the cylinder through the L-shaped frame. A second gear is inserted into the inner side of the insert block. The second gear is fixedly connected to the bottom of the drive shaft. A connecting plate is fixed to the bottom of the second gear. A connecting frame is fixedly connected to the bottom of the insert block. A limiting wheel is fixedly connected to the inner side of the connecting frame. The limiting wheel is located around the connecting plate.

[0015] According to the above technical solution, the insert block is V-shaped, the outer periphery of the limiting wheel is in contact with the outer periphery of the connecting disc, and the limiting wheel is made of wear-resistant material, which facilitates the limiting of the drive shaft when it does not need to work under the action of the second gear and the V-block.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This feed production raw material grinding device, through its first grinding component, seals the bottom of the grinding box under the action of a sealing plate when grinding is required for feed production. A measured amount of feed can then be added into the grinding box, positioned on top of the sealing plate. A first servo motor drives a first rotating rod to rotate, causing the connecting frame to move accordingly. This causes the T-shaped frame to drive a second rotating rod and a first gear to perform circular motion inside the fixed ring. As the first gear rotates, it meshes with an internal gear, further rotating the mounting frame and grinding balls under the action of the first and internal gears. This allows for preliminary grinding of the feed under the action of the grinding balls. Furthermore, the rotation of the grinding balls causes a guide rod to move, guiding the feed and preventing accumulation while ensuring the quality of the grinding. Two sets of connecting frames, including the first rotating rod and the connecting frame, are symmetrically distributed on the left and right sides of the fixed ring, and the two sets of connecting frames are rotatably connected to the T-shaped frame. Inside the frame, not only is the grinding area increased, but the grinding efficiency is also improved, causing the grinding balls to move in a circular motion. The protective door on the front of the protective box allows the feeder to be removed when grinding is complete, thus enabling material unloading.

[0017] 2. This feed production raw material grinding device, through its second grinding component, initially grinds the feed under the action of the grinding box and grinding balls. First, the grinding bucket is positioned at the top of the support base. Then, a third servo motor drives a limit frame connected to the outer thread of a one-way threaded rod to move, inserting the limit frame into the bottom of the grinding bucket. The limit frame, along with a baffle and protective sleeve, slides inside the grinding bucket, sealing the bottom. At this point, the desired feed particle size can be adjusted. Further grinding is then performed by the one-way threaded rod and the limit frame, driving the grinding bucket to grind... The feedstock, which is movable and slidably connected to a suitable position at the bottom of the guide hopper, can enter the grinding hopper after the feedstock has undergone preliminary grinding. Once inside the grinding hopper, the distance between the grinding hopper and the guide hopper can be finely adjusted under the action of the one-way threaded rod. After adjustment, the rotating disk, pull ring, and fixed column can be rotated under the action of the second servo motor, composite pulley, and first rotating shaft. This causes the fixed column to drive the limit frame and grinding hopper to rotate. The cooperation between the grinding rod and the grinding hopper further refines the raw material that has undergone preliminary grinding.

[0018] 3. This feed production raw material grinding device, through its feeding mechanism, firstly drives the second transmission belt, pulley, and drive shaft to rotate under the action of the second servo motor, composite pulley, and first rotating shaft when grinding is required. This causes the first bevel gear to drive the bidirectional threaded rod fixedly connected inside the second bevel gear to rotate. The bidirectional threaded rod drives the moving frame and sealing plate to slide inside the protective box and is located at the bottom of the grinding box. When sealing is complete, the feed can be put into the grinding box and placed on top of the sealing plate. The feed can then undergo preliminary grinding under the action of the grinding balls. When grinding is complete, the sealing plate can be opened to allow the feed to enter the guide hopper inside the protective box for secondary grinding, achieving coordinated operation and improving the grinding quality.

[0019] 4. This feed production raw material grinding device, through its limiting mechanism, seals the bottom of the grinding box under the action of the sealing plate and completes the initial grinding of the feed in the grinding box. When the drive shaft is not required to work, the cylinder drives the insert block to engage inside the second gear, and the insert block drives the connecting frame and the limiting wheel to move, thus limiting the second gear and the connecting plate, thereby limiting the drive shaft. This causes the second transmission belt to slip on the composite pulley without affecting the operation of the grinding bucket driven by the composite pulley and the first transmission belt. It achieves both linkage and separation, ensuring that grinding and sealing / feeding operations do not interfere with each other. The limiting wheel is made of wear-resistant material, and the outer periphery of the limiting wheel is in contact with the outer periphery of the connecting plate. The use of wear-resistant material reduces the wear of the limiting wheel and ensures the stable operation of the limiting mechanism. Attached Figure Description

[0026] See Figures 1-11Furthermore, based on Embodiment 1, the second grinding assembly 32 includes a second servo motor 321, which is fixedly connected to the top of the base plate 6. A first rotating shaft 322 is fixedly connected to the top of the second servo motor 321. A composite pulley 323 is fixedly connected to the periphery of the first rotating shaft 322.

The fixed column 328 is rotatably connected to the inside of the support platform 1. A rectangular frame 3291 is fixedly connected to the top of the fixed column 328. The rectangular frame 3291 is fixedly connected to the protective... Inside box 2, a guide bucket 329 is fixedly connected to the bottom of a rectangular frame 3291, a grinding rod 3295 is fixedly connected to the bottom of the guide bucket 329, a third servo motor 325 is fixedly connected to the bottom of a rotating disk 326, a one-way threaded rod 3292 is fixedly connected to the top of the third servo motor 325, a limit frame 3293 is threadedly connected to the outer periphery of the one-way threaded rod 3292, a grinding bucket 3294 is inserted into the top of the limit frame 3293, the grinding bucket 3294 is slidably connected to the bottom of the guide bucket 329, a baffle 3296 is fixedly connected to the bottom of the inner side of the limit frame 3293, the baffle 3296 is slidably connected to the inside of the grinding bucket 3294, a protective sleeve 3297 is fixedly connected to the top of the baffle 3296, and the grinding bucket 3294 is set on the top of the support base 9.

[0027] Furthermore, the top of the first rotating shaft 322 is rotatably connected to the bottom of the support platform 1, the pull ring 327 is rotatably connected to the bottom of the support platform 1, and the top of the one-way threaded rod 3292 is rotatably connected to the fixed column 328, so that the limiting frame 3293 and the grinding bucket 3294 can be moved under the action of the one-way threaded rod 3292.

[0028] Furthermore, the limiting frame 3293 is slidably connected to the inside of the fixed column 328, and the protective sleeve 3297 is slidably connected to the inside of the grinding hopper 3294. This is to prevent the feed material in the guide hopper 329 from entering the grinding hopper 3294 and to prevent the feed material in the grinding hopper 3294 from being discharged, thanks to the action of the protective sleeve 3297.

[0029] Furthermore, the bottom of the grinding bucket 3294 is in contact with the top of the support base 9, and there are four support bases 9 symmetrically distributed inside the protective box 2. This allows the support bases 9 to support the grinding bucket 3294 when the limiting frame 3293 drives the grinding bucket 3294 down to a certain position, so that the limiting frame 3293 can continue to drive the baffle 3296 to move for material feeding. Example 3

[0030] See Figures 1-11Based on Examples 1 and 2, the feeding mechanism 4 further includes a second transmission belt 41, which is connected to the periphery of the composite pulley 323. A pulley 42 is connected to the inner side of the second transmission belt 41. A drive shaft 43 is fixedly connected inside the pulley 42. The drive shaft 43 is rotatably connected to the support platform 1 and the support frame 311. A first bevel gear 46 is fixedly connected to the periphery of the drive shaft 43.

A sealing plate 49 is fixedly connected to the inner side of the movable frame 48. The sealing plate 49 is slidably connected inside the protective box 2. The sealing plate 49 is located at the bottom of the grinding box 313.

[0031] Furthermore, two sets of movable frames 48 and sealing plates 49 are provided. The two sets of movable frames 48 and sealing plates 49 are symmetrically distributed around the bidirectional threaded rod 45, and the tops of the two sets of sealing plates 49 are in contact with the bottom of the grinding box 313, so that the bottom of the grinding box 313 can be sealed under the action of the sealing plates 49. Example 4

[0032] See Figures 1-11 Based on Examples 1, 2, and 3, the limiting mechanism 8 further includes an L-shaped frame 81, which is fixedly connected to the rear side of the support platform 1. A cylinder 82 is fixedly connected to the rear side of the L-shaped frame 81. An insert block 85 is fixedly connected to the output end of the cylinder 82 through the L-shaped frame 81. A second gear 87 is inserted into the inner side of the insert block 85. The second gear 87 is fixedly connected to the bottom of the drive shaft 43. A connecting plate 86 is fixedly connected to the bottom of the second gear 87. A connecting frame 83 is fixedly connected to the bottom of the insert block 85. A limiting wheel 84 is fixedly connected to the inner side of the connecting frame 83. The limiting wheel 84 is located around the connecting plate 86.

[0033] Furthermore, the insert block 85 is V-shaped, the outer periphery of the limiting wheel 84 is in contact with the outer periphery of the connecting disc 86, and the limiting wheel 84 is made of wear-resistant material, which facilitates the limiting of the drive shaft 43 when it does not need to work under the action of the second gear 87 and the V-block.

[0034] In actual operation, when this device is used, and grinding is required for feed production, the second servo motor 321, the composite pulley 323, and the first rotating shaft 322 drive the second transmission belt 41, the pulley 42, and the drive shaft 43 to rotate. This causes the first bevel gear 46 to drive the bidirectional threaded rod 45 fixedly connected inside the second bevel gear 47 to rotate. The bidirectional threaded rod 45 drives the moving frame 48 and the sealing plate 49 to slide and connect inside the protective box 2, and is located at the bottom of the grinding box 313. The grinding bucket 3294 is located at the top of the support seat 9, and the limiting frame 3293 is located at the bottom of the protective box 2. When the sealing plate 49 is slidably connected inside the protective box 2, the composite pulley 323 and the first rotating shaft 322 can synchronously drive the rotating disk 326 to rotate. The rotating disk 326 drives the bottom of the pull ring 327 support platform 1 to rotate, and the fixed column 328 drives the limiting frame 3293 to rotate. However, the limiting frame 3293 is not inserted into the bottom of the grinding bucket 3294. At this point, a measured amount of feed material can be added into the grinding box 313, which is located on top of the sealing plate 49. The first servo motor 316 drives the first rotating rod 318 to rotate, and the connecting frame 319 moves accordingly, causing T... The T-shaped frame drives the second rotating rod 3193 and the first gear 3192 to perform circular motion inside the fixed ring 314. While the first gear 3192 rotates, it meshes with the inner gear 315, which in turn drives the mounting frame 3195 and the grinding ball 3194 to rotate. The grinding ball 3194 then performs preliminary grinding on the feed. During the rotation of the grinding ball 3194, the guide rod 3196 moves, which guides the feed. This not only prevents the feed from accumulating but also ensures the quality of the feed grinding. There are two sets of connecting frames 319, the first rotating rod 318, and the connecting frames 319, which are symmetrically distributed on the left and right sides of the fixed ring 314. The two sets of connecting frames 319 are rotatably connected to the inside of the T-shaped frame, which not only increases the grinding area but also improves the grinding efficiency, making the grinding ball 3194 move in a circular motion. When the feed material undergoes initial grinding, the third servo motor 325 drives the limiting frame 3293, which is threaded around the one-way threaded rod 3292, to move. The limiting frame 3293 is then inserted into the bottom of the grinding hopper 3294, causing the limiting frame 3293 to slide and connect the baffle 3296 and protective sleeve 3297 inside the grinding hopper 3294, sealing the bottom of the grinding hopper 3294. At this point, the feed material particle size to be ground can be further adjusted. Under the action of the one-way threaded rod 3292 and the limiting frame 3293, the grinding hopper 3294 is moved and slidably connected to a suitable position at the bottom of the guide hopper 329. The second servo motor 321 then reverses, causing the bidirectional threaded rod 45 to drive the moving frame. The sealing plate 49 moves in opposite directions to open the sealing plate 49, allowing the pre-ground feed material to enter the guide bucket 329 inside the protective box 2. When it enters the grinding bucket 3294, the distance between the grinding bucket 3294 and the guide bucket 329 can be finely adjusted under the action of the one-way threaded rod 3292. When the adjustment is completed, the rotating disk 326, the pull ring 327 and the fixed column 328 can be rotated under the action of the second servo motor 321, the composite pulley 323 and the first rotating shaft 322. This causes the fixed column 328 to drive the limit frame 3293 and the grinding bucket 3294 to rotate. The cooperation between the grinding rod 3295 and the grinding bucket 3294 further refines the raw material after the initial grinding. After the initial grinding of the feed material in the grinding box 313 is completed and the drive shaft 43 is no longer needed, the cylinder 82 drives the insert block 85 to engage inside the second gear 87. The insert block 85 then moves the connecting frame 83 and the limiting wheel 84, thus limiting the second gear 87 and the connecting plate 86. This limits the drive shaft 43, causing the second transmission belt 41 to slip on the composite pulley 323. This does not affect the operation of the grinding bucket 3294 driven by the composite pulley 323 and the first transmission belt 324. This achieves both linkage and separation, ensuring that the grinding and sealing feeding operations do not interfere with each other. The limiting wheel 84 is made of wear-resistant material, and its outer periphery is in contact with the outer periphery of the connecting plate 86. The use of wear-resistant material reduces the wear of the limiting wheel 84, ensuring the stable operation of the limiting mechanism 8.

[0035] After two grinding cycles are completed, the one-way threaded rod 3292 can drive the limiting frame 3293 to reverse, causing the limiting frame 3293 to move the grinding bucket 3294 downward. When the grinding bucket 3294 moves to a certain position, it will contact the top of the support base 9. At this time, the grinding bucket 3294 will not continue to move downward, but the limiting frame 3293 will continue to drive the baffle 3296 and the protective sleeve 3297 to move away from the inside of the grinding bucket 3294, so that the ground feed can be unloaded, improving the unloading efficiency. When the protective sleeve 3297 moves downward, it does not need to slide completely out of the grinding bucket 3294, thus providing a certain degree of protection for the fixed column 328 and preventing the feed from entering the fixed column 328 and affecting the rotation of the one-way threaded rod 3292. If a small amount of feed enters, it can be cleaned by external cleaning equipment. After unloading is completed, the protective door 7 can be opened to collect the feed.
