Description

Technical Field

[0001] The invention relates to the technical field of feed production, and in particular to a feed production grinding device and a grinding method for beef cattle breeding. Background Art

[0002] According to the Chinese patent publication number "CN117380326B", a patent document entitled "A grinding device and grinding method for the production of feed for beef cattle breeding" is disclosed. The method used in the patent application is to level the rollers and self-clean the annular block used to clean the connecting rod. When the annular block descends, the dust on the top will not remain on the surface of the connecting rod. However, this grinding method usually has the following problems:

[0003] First, the existing grinding device cannot control the grinding degree during the grinding process. If the powder generated by grinding the raw material is not collected in time, the powder generated by the grinding will be compacted as the grinding progresses, and then stick to the grinding piece or directly penetrate into the gaps of the raw material, which will cause low grinding efficiency.

[0004] Secondly, the size of the gap between the grinding piece and the grinding chamber is one of the conditions that determine the degree of grinding. If the gap between the two is too large, the raw materials will not be fully ground and larger particles will be mixed in the mixture. If the raw materials are directly ground by fine grinding, large pieces of raw materials will not be able to enter the gap between the grinding piece and the grinding chamber for grinding. At the same time, the gap areas between the existing grinding pieces and the grinding chamber are of different sizes, so it is easy for large pieces of raw materials to be stuck in a large area, making it impossible to grind this piece of raw material. Therefore, a grinding device is required in which the gap size between the grinding piece and the grinding chamber is a fixed value and the grinding gap can be changed.

[0005] Therefore, we designed a grinding device and a grinding method for feed production based on beef cattle breeding. Summary of the invention

[0019] Preferably, the oil pipe is connected to the oil holes one by one through a plurality of rubber hoses.

[0020] A grinding method based on a feed production grinding device for beef cattle breeding, the specific operating steps are as follows:

[0021] S1: First, the feed to be ground is put into the lifting ball table in the grinding base body, wherein the feed to be ground is located in the gap between the grinding assembly and the lifting ball table, and then the external driving mechanism is turned on to drive the grinding assembly in the ball storage box to rotate together, that is, the feed in the gap between the grinding assembly and the lifting ball table is rotated and ground;

[0022] S2: During the grinding process, the third hemispherical piece is in the initial grinding state with the lifting ball table. At this time, the gap distance between the surface of the third hemispherical piece and the lifting ball table is A. Therefore, when the ball storage box drives the third hemispherical piece to rotate and grind through the fixed shaft, the large pieces of feed will be ground. At the same time, due to the multiple scratching grooves set on the upper surface of the lifting ball table, the third hemispherical piece will continuously push the feed to slide through the scratching grooves during the grinding process of the feed. Therefore, the powder generated during the grinding process will accumulate in the scratching grooves. At the same time, the powder originally attached to the surface of the feed will also be scraped into the scratching grooves during the sliding process of the scratching grooves, that is, the first grinding of the feed is completed, and the collection of the feed powder is completed at the same time;

[0023] S3: During grinding, the rotation of the ball storage box will drive the concave-convex ring plate to rotate together. During the rotation process, the convex block at the bottom of the concave-convex ring plate cooperates with the reset spring in the lifting groove to continuously press the L-shaped rod to drive the L-shaped rod to reciprocate up and down. The L-shaped rod is connected to the lifting ball table, so it will also drive the lifting ball table to rise and fall and slide in the limit ring. During the reciprocating lifting process of the lifting ball table, the feed in the lifting ball table will be continuously shaken, and the position of the feed can be continuously adjusted;

[0024] S4: During the lifting process of the lifting ball table, the lifting ball table will lift and reciprocate with the oil pipe. Since the piston rod reciprocates relative to the oil pipe, the oil will be driven to pump back and forth in the oil hole, thereby driving the sliding plate in the sliding cavity connected to the sliding cavity to slide back and forth. The powder originally in the scratch groove will be in the powder groove on the sliding plate. As the sliding plate slides toward the brush direction, this part of the powder will be brushed into the sliding cavity, and will flow out from the discharge hole into the inclined cavity, and then out from the leakage pipe, thereby completing the grinding of the feed;

[0025] S5: After the third hemispherical part grinds the feed, the volume of the originally large feed will become smaller, and then the electric hydraulic cylinder is turned on to drive the telescopic rod to push the semi-cylinder to move. In the initial state, the third hemispherical part is arranged opposite to the first hemispherical part and the second hemispherical part. Under the push of the semi-cylinder, the threaded strip will slide against the propulsion block in the semicircular hole, and the threaded strip is in a half-circle state, so it will push the second hemispherical part carrying the propulsion block to rotate half a circle and resist the propulsion block on the semi-cylinder plane, ensuring that the second hemispherical part is fixed after rotating half a circle, and finally realizing the rotation switching of the second hemispherical part. During the switching process of the second hemispherical part, the second hemispherical part can not only scrape off the powder originally attached to the surface of the third hemispherical part and drop it on the lifting ball table, but also because of the continuous lifting of the lifting ball table, it is avoided that the second hemispherical part switches and pushes the feed away from the lifting ball table;

[0026] Since the gap distance between the surface of the third hemispherical part and the lifting ball table is A, with the switching of the second hemispherical part, the second hemispherical part is covered on the outer wall of the third hemispherical part, so the gap distance between the surface of the second hemispherical part and the lifting ball table is B. Similarly, for the switching of the first hemispherical part, the gap distance between the surface of the first hemispherical part and the lifting ball table is C, A>B>C, so with the switching of the second hemispherical part and the first hemispherical part, the degree of grinding of the feed will be deepened, thereby completing the control of the degree of grinding of the feed and improving the grinding efficiency.

[0027] The beneficial effects of the present invention are:

[0028] 1. In the process of grinding the feed by the grinding assembly of the present invention, the feed will be continuously pushed to slide through the scratch groove, so the powder generated in the grinding process will be accumulated in the scratch groove, and the powder originally adhering to the surface of the feed will also be scraped into the scratch groove in the process of sliding through the scratch groove, thus completing one grinding of the feed and collecting the feed powder at the same time.

[0029] 2. In the present invention, the gap distance between the surface of the third hemispherical part and the lifting ball table is A. With the switching of the second hemispherical part, the second hemispherical part is covered on the outer wall of the third hemispherical part, so the gap distance between the surface of the second hemispherical part and the lifting ball table is B. Similarly, with the switching of the first hemispherical part, the gap distance between the surface of the first hemispherical part and the lifting ball table is C, A>B>C, so with the switching of the second hemispherical part and the first hemispherical part, the degree of grinding of the feed will be deepened, thereby completing the control of the degree of grinding of the feed and improving the grinding efficiency.

DETAILED DESCRIPTION

[0040] Reference Figure 1-Figure 9 A grinding device for producing feed for beef cattle breeding includes a grinding base body 1 and an external driving mechanism. A plurality of brackets 2 are provided at the bottom of the grinding base body 1. A ball storage box 4 rotates coaxially on the grinding base body 1 through balls 8 and ball grooves 9. The balls 8 are arranged on the outer wall of the ball storage box 4. The ball grooves 9 are opened on the inner wall of the grinding base body 1. A gap is left between the ball storage box 4 and the grinding base body 1. The corresponding feed to be ground is put into the lifting ball table 11 in the grinding base body 1.

[0041] The feed to be ground is located in the space between the grinding assembly and the lifting ball table 11, and then the external driving mechanism is turned on to drive the grinding assembly in the ball storage box 4 to rotate together, that is, the feed in the gap between the grinding assembly and the lifting ball table 11 is rotated and ground.

[0042] An inclined cavity 22 with a conical bottom is provided on the grinding base body 1, and a ring-shaped limiting ring 12 is fixed on the inclined cavity 22. A lifting ball table 11 that slides up and down is provided on the limiting ring 12. During the grinding process, the third hemispherical piece 7 is in an initial grinding state in cooperation with the lifting ball table 11. At this time, the gap distance between the surface of the third hemispherical piece 7 and the lifting ball table 11 is A. Therefore, when the ball storage box 4 drives the third hemispherical piece 7 to rotate and grind through the fixed shaft 27, large pieces of feed will be ground.

[0043] The outer side wall of the ball storage box 4 is provided with an intermittent lifting part for driving the lifting ball table 11 to reciprocate and lift. The intermittent lifting part includes a concave-convex ring plate 10 and an L-shaped rod 23. The concave-convex ring plate 10 is coaxially fixed to the outer side wall of the ball storage box 4 in a circular shape. A plurality of protrusions are provided at the bottom of the concave-convex ring plate 10, and the space between two adjacent protrusions is smooth. A lifting groove 24 is provided on the limit ring 12, and the L-shaped rod 23 is lifted and lowered in the lifting groove 24. One end of the L-shaped rod 23 is fixed to the outer side wall of the lifting ball table 11, and the other end of the L-shaped rod 23 is against the plurality of protrusions at the bottom of the concave-convex ring plate 10, wherein a return spring 25 for pushing the L-shaped rod 23 to lift is provided in the lifting groove 24.

[0044] The rotation of the ball storage box 4 will drive the concave-convex ring plate 10 to rotate together. During the rotation process, the convex block at the bottom of the concave-convex ring plate 10 cooperates with the reset spring 25 in the lifting groove 24 to continuously press the L-shaped rod 23 to drive the L-shaped rod 23 to reciprocate up and down. The L-shaped rod 23 is connected to the lifting ball table 11, so it will also drive the lifting ball table 11 to rise and fall and slide in the limit ring 12.

[0045] During the reciprocating lifting process of the lifting ball table 11, the feed inside the lifting ball table 11 will be continuously shaken, and the position of the feed can be continuously adjusted.

[0046] The lifting ball table 11 is provided with a plurality of scratch grooves 13 for scratching the feed and for temporarily storing the feed powder. Since the plurality of scratch grooves 13 are provided on the upper surface of the lifting ball table 11, the third hemisphere 7 will continuously push the feed to slide through the scratch grooves 13 during the grinding process of the feed, so the powder generated during the grinding process will accumulate in the scratch grooves 13. At the same time, the powder originally stuck on the surface of the feed will also be scraped into the scratch grooves 13 during the process of sliding through the scratch grooves 13, thus completing one grinding of the feed and completing the collection of the feed powder at the same time.

[0047] The lifting ball table 11 is also provided with a plurality of sliding chambers 14 connected with the scratch grooves 13, and the sliding plate 15 slides in the sliding chamber 14, and the oil pipe 20 is connected with the sliding chamber 14 through the oil hole 19, and the oil pipe 20 is connected with the oil hole 19 one by one through a plurality of rubber hoses. In the process of lifting and lowering the lifting ball table 11, the lifting ball table 11 will lift and lower back and forth with the oil pipe 20. Since the piston rod 21 reciprocates relative to the oil pipe 20, it will drive the oil to reciprocate in the oil hole 19, thereby driving the sliding plate 15 in the sliding chamber 14 connected with the sliding chamber 14 to slide back and forth.

[0048] The lifting ball table 11 is also provided with a plurality of sliding plates 15 for pushing the powder in the scratch groove 13 into the inclined cavity 22, and the bottom of the lifting ball table 11 is also provided with an oil pulling part for reciprocating the sliding plate 15. The oil pulling part includes an oil pipe 20, which is coaxially fixed to the bottom of the lifting ball table 11, and a piston rod 21 is arranged in the oil pipe 20, the leakage pipe 3 is fixed to the bottom of the grinding base body 1, and the leakage pipe 3 is connected to the inclined cavity 22, and the piston rod 21 is fixed in the leakage pipe 3 through a connecting frame.

[0049] A plurality of powder troughs 16 are provided on the top of the sliding plate 15, and a brush 17 for brushing off the feed powder on the powder trough 16 is provided on the inner wall of the sliding cavity 14 on one side of the scratching groove 13. A discharge hole 18 connected to the inclined cavity 22 is also provided on the sliding cavity 14, wherein the powder originally existing in the scratching groove 13 will exist in the powder trough 16 on the sliding plate 15. As the sliding plate 15 slides toward the direction of the brush 17, this part of the powder will be brushed into the sliding cavity 14, and will flow out from the discharge hole 18 into the inclined cavity 22, and will flow out from the leakage pipe 3, thereby completing the grinding of the feed.

[0050] A ball storage box 4 is provided above the grinding base body 1 and is coaxially fixed with the output end of the external driving mechanism. A grinding assembly for grinding feed is provided on the ball storage box 4. The grinding assembly includes a first hemispherical part 5, a second hemispherical part 6 and a third hemispherical part 7. The first hemispherical part 5, the second hemispherical part 6 and the third hemispherical part 7 are all rotated through a fixed shaft 27.

[0051] The fixed shaft 27 is hollow inside, and the first hemispherical member 5, the second hemispherical member 6 and the third hemispherical member 7 rotate on the outer wall of the fixed shaft 27 through the semicircular hole 31 and the propulsion block 32. After the third hemispherical member 7 grinds the feed, the original large piece of feed will become smaller in volume, and then the electric hydraulic cylinder 26 is turned on to drive the telescopic rod 28 to push the semi-cylinder 29 to move.

[0052] The first hemispherical member 5 , the second hemispherical member 6 and the third hemispherical member 7 are covered in order from large to small radius and rotate on the fixed shaft 27 . The fixed shaft 27 is fixed in the ball storage box 4 , and an electric hydraulic cylinder 26 is fixed on the fixed shaft 27 .

[0053] A plurality of semicircular holes 31 are linearly opened on the outer wall of the fixed shaft 27, and a push block 32 extends into the hollow of the fixed shaft 27. A telescopic rod 28 is fixed to the output end of the electric hydraulic cylinder 26, and a semi-cylinder 29 is fixed to one end of the telescopic rod 28. A threaded strip 30 abutting against the push block 32 is provided on the outer wall of the semi-cylinder 29, and the push of the semi-cylinder 29 drives the third hemispherical part 7, the second hemispherical part 6 and the first hemispherical part 5 to flip in turn.

[0054] In the initial state, the third hemispherical part 7 is arranged opposite to the first hemispherical part 5 and the second hemispherical part 6. Under the push of the semi-cylinder 29, the threaded bar 30 will slide in the semicircular hole 31 against the pushing block 32, wherein the threaded bar 30 is in a half-circle state, and thus will push the second hemispherical part 6 carrying the pushing block 32 to rotate half a circle, and will press against the pushing block 32 in the plane of the semi-cylinder 29, ensuring that the second hemispherical part 6 is fixed after rotating half a circle, thereby finally realizing the rotation switching of the second hemispherical part 6.

[0055] The first hemispherical piece 5, the second hemispherical piece 6 and the third hemispherical piece 7 are attached to each other in sequence, and the first hemispherical piece 5, the second hemispherical piece 6 and the third hemispherical piece 7 all rotate half a circle around the fixed axis 27 and are in the same direction as the opening of the lifting ball table 11. During the switching process of the second hemispherical piece 6, the second hemispherical piece 6 can not only scrape off the powder originally stuck on the surface of the third hemispherical piece 7 and drop it on the lifting ball table 11, but also due to the continuous lifting and lowering of the lifting ball table 11, the switching of the second hemispherical piece 6 can be avoided to push the feed away from the lifting ball table 11.

[0056] Since the gap distance between the surface of the third hemispherical component 7 and the lifting ball table 11 is A, with the switching of the second hemispherical component 6, the second hemispherical component 6 is covered on the outer wall of the third hemispherical component 7, so the gap distance between the surface of the second hemispherical component 6 and the lifting ball table 11 is B. Similarly, for the switching of the first hemispherical component 5, the gap distance between the surface of the first hemispherical component 5 and the lifting ball table 11 is C, A>B>C, so with the switching of the second hemispherical component 6 and the first hemispherical component 5, the degree of grinding of the feed will be deepened, thereby completing the control of the degree of feed grinding and the improvement of grinding efficiency.

[0057] The working principle of the present invention is as follows:

[0058] S1: First, the feed to be ground is put into the lifting ball table 11 in the grinding base body 1, wherein the feed to be ground is located in the gap between the grinding assembly and the lifting ball table 11, and then the external driving mechanism is turned on to drive the grinding assembly in the ball storage box 4 to rotate together, that is, the feed in the gap between the grinding assembly and the lifting ball table 11 is rotated and ground;

[0059] S2: During the grinding process, the third hemispherical member 7 is in the initial grinding state with the lifting ball table 11. At this time, the gap distance between the surface of the third hemispherical member 7 and the lifting ball table 11 is A. Therefore, when the ball storage box 4 drives the third hemispherical member 7 to rotate and grind through the fixed shaft 27, the large pieces of feed will be ground. At the same time, due to the multiple scratch grooves 13 set on the upper surface of the lifting ball table 11, the third hemispherical member 7 will continuously push the feed to slide through the scratch grooves 13 during the grinding process of the feed. Therefore, the powder generated during the grinding process will accumulate in the scratch grooves 13. At the same time, the powder originally attached to the surface of the feed will also be scraped into the scratch grooves 13 during the process of sliding through the scratch grooves 13, that is, the first grinding of the feed is completed, and the collection of the feed powder is completed at the same time;

[0060] S3: During grinding, the rotation of the ball storage box 4 will drive the concave-convex ring plate 10 to rotate together. During the rotation, the convex block at the bottom of the concave-convex ring plate 10 cooperates with the reset spring 25 in the lifting groove 24 to continuously press the L-shaped rod 23 to drive the L-shaped rod 23 to reciprocate up and down. The L-shaped rod 23 is connected to the lifting ball table 11, so it will also drive the lifting ball table 11 to rise and slide in the limit ring 12. During the reciprocating lifting process of the lifting ball table 11, the feed in the lifting ball table 11 will be continuously shaken, and the position of the feed can be continuously adjusted;

[0061] S4: During the lifting and lowering process of the lifting ball table 11, the lifting ball table 11 will lift and lower the oil pipe 20 together. Since the piston rod 21 reciprocates relative to the oil pipe 20, the oil will be pumped back and forth in the oil hole 19, thereby driving the sliding plate 15 in the sliding chamber 14 connected to the sliding chamber 14 to slide back and forth, wherein the powder originally existing in the scratching groove 13 will exist in the powder groove 16 on the sliding plate 15. As the sliding plate 15 slides toward the brush 17, this part of the powder will be brushed into the sliding chamber 14, and will flow out from the discharge hole 18 into the inclined chamber 22, and will flow out from the leakage pipe 3, thereby completing the grinding of the feed;

[0062] S5: After the third hemispherical component 7 grinds the feed, the volume of the originally large feed will become smaller, and then the electric hydraulic cylinder 26 is turned on to drive the telescopic rod 28 to push the semi-cylinder 29 to move. In the initial state, the third hemispherical component 7 is arranged opposite to the first hemispherical component 5 and the second hemispherical component 6. Under the push of the semi-cylinder 29, the threaded bar 30 will slide against the propulsion block 32 in the semicircular hole 31, wherein the threaded bar 30 is in a half-circle state, so it will push the second hemispherical component 6 carrying the propulsion block 32 to rotate half a circle, and resist the propulsion block 32 on the plane of the semi-cylinder 29, ensuring that the second hemispherical component 6 is fixed after rotating half a circle, and finally realizing the rotation switching of the second hemispherical component 6. During the switching process of the second hemispherical component 6, the second hemispherical component 6 can not only scrape off the powder originally attached to the surface of the third hemispherical component 7 and drop it on the lifting ball table 11, but also due to the continuous lifting of the lifting ball table 11, it is avoided that the second hemispherical component 6 switches to push the feed away from the lifting ball table 11.

[0063] Since the gap distance between the surface of the third hemispherical component 7 and the lifting ball table 11 is A, with the switching of the second hemispherical component 6, the second hemispherical component 6 is covered on the outer wall of the third hemispherical component 7, so the gap distance between the surface of the second hemispherical component 6 and the lifting ball table 11 is B. Similarly, for the switching of the first hemispherical component 5, the gap distance between the surface of the first hemispherical component 5 and the lifting ball table 11 is C, A>B>C, so with the switching of the second hemispherical component 6 and the first hemispherical component 5, the degree of grinding of the feed will be deepened, thereby completing the control of the degree of feed grinding and the improvement of grinding efficiency.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

10. A grinding method based on a grinding device for the production of feed for beef cattle, applied to the grinding device for the production of feed for beef cattle in claim 9, characterized in that: The specific steps are as follows: S1: First, the feed to be ground is placed on the lifting ball table (11) in the grinding base body (1), wherein the feed to be ground is located in the gap between the grinding component and the lifting ball table (11), and then the external driving mechanism is turned on to drive the grinding component in the ball storage box (4) to rotate together, that is, the feed in the gap between the grinding component and the lifting ball table (11) is rotated and ground; S2: During the grinding process, the third hemispherical member (7) is initially in a grinding state in cooperation with the lifting ball table (11). At this time, the gap distance between the surface of the third hemispherical member (7) and the lifting ball table (11) is A. Therefore, when the ball storage box (4) drives the third hemispherical member (7) to rotate and grind through the fixed shaft (27), large pieces of feed will be ground. At the same time, due to the multiple scratching grooves (13) provided on the upper surface of the lifting ball table (11), during the grinding process of the feed by the third hemispherical member (7), the feed will be continuously pushed to slide through the scratching grooves (13). Therefore, the powder generated during the grinding process will be accumulated in the scratching grooves (13). At the same time, the powder originally attached to the surface of the feed will also be scraped into the scratching grooves (13) during the sliding process of the scratching grooves (13). That is, the first grinding of the feed is completed, and the collection of the feed powder is completed at the same time; S3: During grinding, the rotation of the ball storage box (4) drives the concave-convex ring plate (10) to rotate together. During the rotation process, the convex block at the bottom of the concave-convex ring plate (10) cooperates with the return spring (25) in the lifting groove (24) to continuously press the L-shaped rod (23) to drive the L-shaped rod (23) to reciprocate up and down. The L-shaped rod (23) is connected to the lifting ball table (11), so it also drives the lifting ball table (11) to rise and fall and slide in the limit ring (12). During the reciprocating lifting process of the lifting ball table (11), the feed in the lifting ball table (11) is continuously shaken, and the position of the feed can be continuously adjusted; S4: During the lifting and lowering process of the lifting ball table (11), the lifting ball table (11) will lift and lower the oil pipe (20) together. Since the piston rod (21) reciprocates relative to the oil pipe (20), the oil will be driven to pump back and forth in the oil hole (19), thereby driving the sliding plate (15) in the sliding chamber (14) connected to the sliding chamber (14) to slide back and forth. The powder originally existing in the scratch groove (13) will be stored in the powder groove (16) on the sliding plate (15). As the sliding plate (15) slides toward the brush (17), this part of the powder will be brushed into the sliding chamber (14), and will flow out from the discharge hole (18) into the inclined chamber (22), and will flow out from the leakage pipe (3), thereby completing the grinding of the feed; S5: After the third hemispherical member (7) grinds the feed, the original bulk of the feed will become smaller in size, and then the electric hydraulic cylinder (26) is turned on to drive the telescopic rod (28) to push the semi-cylinder (29) to move. In the initial state, the third hemispherical member (7) is arranged opposite to the first hemispherical member (5) and the second hemispherical member (6). Under the push of the semi-cylinder (29), the threaded strip (30) will slide against the propulsion block (32) in the semi-circular hole (31), wherein the threaded strip (30) is in a half-circle state, and thus it will push the second hemispherical member (5) carrying the propulsion block (32). The ball piece (6) rotates half a circle and contacts the push block (32) on the plane of the semi-cylinder (29), ensuring that the second hemispherical piece (6) is fixed after rotating half a circle, and finally realizing the rotation switching of the second hemispherical piece (6). During the switching process of the second hemispherical piece (6), the second hemispherical piece (6) can not only scrape off the powder originally adhering to the surface of the third hemispherical piece (7) and drop it on the lifting ball table (11), but also because the lifting ball table (11) is continuously lifted and lowered, it is prevented that the second hemispherical piece (6) switches and pushes the feed away from the lifting ball table (11); Since the gap distance between the surface of the third hemispherical member (7) and the lifting ball platform (11) is A, as the second hemispherical member (6) is switched, the second hemispherical member (6) is covered on the outer wall of the third hemispherical member (7), so the gap distance between the surface of the second hemispherical member (6) and the lifting ball platform (11) is B. Similarly, for the switching of the first hemispherical member (5), the gap distance between the surface of the first hemispherical member (5) and the lifting ball platform (11) is C, A>B>C, so as the second hemispherical member (6) and the first hemispherical member (5) are switched, the grinding degree of the feed will be deepened, thereby completing the control of the grinding degree of the feed and improving the grinding efficiency.
