Description

Technical Field

[0001] The present invention relates to the technical field of crushing equipment, and specifically relates to an automated feed crushing device for pig breeding. Background Art

[0002] When breeding livestock, livestock cubs are generally fed with feed. For example, when feeding piglets, the feed usually needs to be mashed for feeding the piglets. The purpose of mashing is to prevent the feed with large particles and relatively hard surface from causing indigestion in piglets. The reason why the feed usually has a relatively hard surface is that during feed processing, the compression ratio value of the granulator is relatively high, which makes the surface of the feed relatively hard. Piglets are difficult to bite open the feed with a relatively hard surface. In the prior art, a crushing device is used to crush the feed with large particles and relatively hard surface for piglets to eat. However, the current crushing devices usually split the feed as a whole, and the surface hardness of the feed is still relatively high. Moreover, due to the large degree of splitting of the feed, the feed may even become powdery, which may affect the digestive function of piglets and the palatability of the feed. Therefore, a crushing device that can process the feed with a relatively hard surface and does not cause a large degree of splitting of the feed is needed. Summary of the Invention

[0003] The purpose of the present invention is to provide an automated feed crushing device for pig breeding to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: An automated feed crushing device for pig breeding, including a machine base, further including: A rotating seat rotatably connected to the top of the machine base. The rotating seat is axially provided with a plurality of fan-shaped plates in an array. The rotating seat and the plurality of fan-shaped plates together form a disc-shaped structure. The surface of the fan-shaped plate is provided with a plurality of sieve holes. The top surface of the rotating seat is provided with a plurality of concave sliding cavities, and the sliding cavities are located between two adjacent fan-shaped plates; A wedge-shaped part snap-fitted in the sliding cavity and freely sliding up and down. The upward-facing surface of the wedge-shaped part is provided with a first inclined surface. The rotating seat is provided with a reset unit, and the reset unit gives the wedge-shaped part the potential energy to move upward; A lifting unit provided on the top of the machine base. The lifting unit is drivingly connected to a feeding unit. The lifting unit drives the feeding unit to move vertically. The feeding unit is provided with a fixed seat, and the fixed seat is coaxial with the rotating seat; A driving part fixed to the bottom surface of the fixed seat. The bottom surface of the driving part is provided with a second inclined surface that cooperates with the first inclined surface, and the first inclined surface and the second inclined surface are not parallel.

[0005] Through the above technical solution, the feed enters between the fixed seat and the rotating seat, and the rotating seat rotates, so that the driving part drives the feed to the first inclined surface of the wedge part, causing the feed to be squeezed and rubbed by the second inclined surface on the driving part and the first inclined surface on the wedge part, so that the surface of the feed is ground, and then the harder surface of the feed is ground off, and at the same time, the feed will not be split into multiple pieces, so that the palatability of the feed will not be affected, and it is convenient for piglets to feed and digest.

[0006] Further, the machine base is vertically rotatably connected with a main shaft, the rotating seat is coaxially connected with the upper end of the main shaft, and the main shaft is driven to rotate by a reduction motor installed on the machine base.

[0007] Through the above technical solution, the reduction motor drives the main shaft to rotate, and then drives the rotating seat to rotate, so that the fixed seat and the rotating seat can generate relative rotational motion.

[0008] Further, the lifting unit includes columns vertically installed on both sides of the machine base. The upper ends of the two columns are horizontally connected with a mounting plate. A cylinder is vertically installed on the top of the mounting plate. The cylinder is drivingly connected with a lifting plate. Guide columns are vertically connected to both ends of the lifting plate. The mounting plate is vertically embedded with a bushing, and the guide columns are slidably arranged through the bushing.

[0009] Through the above technical solution, the cylinder rod of the cylinder extends or contracts to drive the lifting plate to move up or down, so that the lifting plate can drive the fixed seat to move up and down. At the same time, the guide columns slide in the bushings, which can guide the vertical movement of the lifting plate.

[0010] Further, the feeding unit includes a mounting frame connected to the bottom of the lifting plate. A conveying cylinder is vertically installed at the bottom of the mounting frame. The lower end of the conveying cylinder is connected to the top surface of the fixed seat. A plurality of feeding ports communicating with the conveying cylinder are opened on the top surface of the fixed seat. A servo motor is vertically installed on the mounting frame. The servo motor is drivingly connected with a spiral auger. The spiral auger is coaxially installed in the conveying cylinder, and the conveying cylinder is provided with a hopper penetrating its inner cavity.

[0011] Through the above technical solution, the feed is put into the hopper, and the servo motor drives the spiral auger to rotate, so that the spiral auger can convey the feed to between the fixed seat and the rotating seat through the feeding port, realizing the feeding of the feed.

[0012] Further, a grinding layer is provided on the first inclined surface of the wedge part.

[0013] Through the above technical solution, the grinding layer generates a large frictional force on the surface of the feed, so that the surface of the feed can be ground off more smoothly.

[0014] Furthermore, a cutting edge is provided at the upper end of the wedge portion, and a material blocking structure is provided on the driving portion, and the material blocking structure is used in cooperation with the cutting edge.

[0015] Through the above technical solution, when the feed is driven by the driving portion to the upper end of the first inclined surface, the driving portion will be disengaged from the wedge portion. At the moment of disengagement, the cutting edge will squeeze the feed, causing the feed to be squeezed into the material blocking structure. Under the driving of the elastic abutting force of the reset unit on the wedge portion, the cutting edge will move upward and cut the feed stuck in the material blocking structure, so that the feed is cut open, and thus the large-particle feed can be separated. This will neither cause the feed to split into multiple parts and affect palatability, nor reduce the volume of the feed, making it convenient for piglets to digest and consume.

[0016] Furthermore, the material blocking structure includes a material blocking portion fixedly connected to the outer wall of the driving portion. A material blocking groove is formed on the downward-facing surface of the material blocking portion, and the inner wall of the material blocking groove is inclined in a slope shape facing the driving portion.

[0017] Through the above technical solution, the cutting edge will squeeze the feed, causing the feed to be squeezed into the material blocking groove. Since the inner wall of the material blocking groove is inclined, the feed will continue to be squeezed by the cutting edge for a period of time after being stuck in the material blocking groove, enabling the cutting edge to cut the feed.

[0018] Furthermore, the reset unit includes a sliding column vertically and slidably passing through the rotating seat. The upper end of the sliding column is fixedly connected to the bottom surface of the wedge portion, and a nut is threadedly sleeved on the lower end. A spring is wound around the periphery of the sliding column, and the spring imparts potential energy for the wedge portion to move upward.

[0019] Through the above technical solution, the spring has an upward elastic abutting force on the wedge portion. Thus, after the wedge portion is disengaged from the driving portion, the spring will drive the wedge portion to move upward.

[0020] Furthermore, one end of the sector plate facing the radially inner side of the rotating seat is rotatably connected to the rotating seat. A lifting ring is sleeved on a plurality of the sliding columns together. The lifting ring is limited and connected to the sliding columns through the nut, and a protruding portion is fixedly connected to the upper end surface of the lifting ring. The protruding portion is in contact connection with the bottom surface of the sector plate.

[0021] Through the above technical solution, when the driving portion is in contact with the wedge portion, it will generate a downward pressure on the wedge portion, causing the wedge portion to drive the sliding column to move downward, and further causing the lifting ring to move downward. Under the action of its own weight, the sector plate will swing downward along the rotation fulcrum on the rotating seat, enabling the feed on the surface of the sector plate that has not been ground to disperse in the radially outer direction of the rotating seat, avoiding the feed transported by the conveying cylinder between the rotating seat and the fixed seat from accumulating in the middle area of the rotating seat.

[0022] Furthermore, a short pin is fixedly connected to the side wall of the sector plate, and an arc-shaped groove for the short pin to be inserted into is formed on the surface of the rotating seat.

[0023] Through the above technical solution, the short pin slides in the arc groove, so that the fan-shaped plate can be limited when swinging upward or downward, that is, the fan-shaped plate can swing in a small range.

[0024] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the feed enters between the fixed seat and the rotating seat, and the rotating seat rotates, so that the driving part drives the feed to the first inclined surface of the wedge-shaped part, so that the feed is squeezed and rubbed by the second inclined surface of the driving part and the first inclined surface of the wedge-shaped part, so that the surface of the feed is ground, and the surface with greater hardness of the feed is ground away, and at the same time, the feed will not be split into multiple pieces, and the palatability of the feed will not be affected, and it is convenient for suckling pigs to feed and digest; 2. In the present invention, when the feed is driven to the upper end of the first inclined surface by the driving part, the driving part will be out of contact with the wedge-shaped part. At the moment of the out of contact, the cutting blade will squeeze the feed so that the feed is squeezed into the material blocking structure. Driven by the elastic supporting force of the wedge-shaped part by the reset unit, the cutting blade will move upward and cut the feed stuck in the material blocking structure, so that the feed is cut, and then the large particles of feed can be separated, which will not cause the feed to be split into multiple parts and affect the palatability, but can also reduce the volume of the feed, making it easier for suckling pigs to digest and eat; 3. In the present invention, when the driving part contacts with the wedge-shaped part, it will generate downward pressure on the wedge-shaped part, so that the wedge-shaped part drives the sliding column to move downward, and then the lifting ring moves downward. Under the action of its own weight, the fan-shaped plate will produce a downward swinging movement along the rotating fulcrum on the rotating seat, so that the unground feed on the surface of the fan-shaped plate can be dispersed toward the radial outside direction of the rotating seat, avoiding the feed delivered by the conveying cylinder to between the rotating seat and the fixed seat from accumulating in the middle area of the rotating seat.

The cylinder 7 is drivingly connected to a lifting plate 6. Guide columns 8 are vertically connected to both ends of the lifting plate 6. The mounting plate 9 is vertically embedded with a bushing. The guide columns 8 are slidably inserted through the bushing. Due to the cooperation between the bushing and the guide columns 8, the lifting plate 6 can be guided when the cylinder 7 drives it to move vertically. The bottom of the lifting plate 6 is screw-connected with a mounting frame 10. A conveying cylinder 4 is vertically installed at the bottom of the mounting frame 10. The lower end of the conveying cylinder 4 is coaxially connected with a fixed seat 3. The fixed seat 3 is located above the rotating seat 16 and is also in a coaxial state with the rotating seat 16. A plurality of feeding ports 14 communicating with the conveying cylinder 4 are formed on the top surface of the fixed seat 3. A servo motor 12 is vertically installed on the mounting frame 10. The servo motor 12 is drivingly connected to a spiral auger 13. The spiral auger 13 is coaxially installed inside the conveying cylinder 4. A hopper 5 is welded to the outer wall of the conveying cylinder 4. The mouth of the hopper 5 faces upward and is communicated with the inner cavity of the conveying cylinder 4. A collecting bin 2 is installed on the top of the machine base 1. The collecting bin 2 covers the outside of the rotating seat 16. The inner diameter dimension of the collecting bin 2 is adapted to the outer diameter dimensions of the rotating seat 16 and the fixed seat 3, and a blanking chute (such as Figure 1 shown in the figure) is installed on the collecting bin 2. The blanking chute is located below the rotating seat 16 and is provided with a through hole for the main shaft to pass through freely on its surface. The blanking chute is in an inclined state. An outlet is formed on the outer wall of the collecting bin 2. The lower end of the blanking chute passes out through the outlet; A plurality of recessed sliding cavities 17 are formed on the top surface of the rotating seat 16. The sliding cavities 17 are located between two adjacent sector plates 15. A wedge-shaped part 22 that can slide up and down freely is snap-fitted and installed inside the sliding cavity 17. A diversion and dispersion cone 27 is provided in the middle of the upper end surface of the rotating seat 16. The diversion and dispersion cone 27 is used to evenly disperse the feed entering between the fixed seat 3 and the rotating seat 16 from the feeding port 14 onto the plurality of sector plates 15. The upward-facing surface of the wedge-shaped part 22 is provided with a first inclined surface. The first inclined surface faces the front side of the rotation direction of the rotating seat 16. A plurality of driving parts 23 are fixedly connected to the bottom surface of the fixed seat 3 along its axial array. The bottom surface of the driving part 23 is provided with a second inclined surface that cooperates with the first inclined surface. The second inclined surface faces the rear side of the rotation direction of the rotating seat 16. The first inclined surface and the second inclined surface are not parallel. Refer to Figure 6 the figure, when the driving part 23 and the wedge-shaped part 22 are as shown in Figure 6When in the shown position, the first inclined surface and the second inclined surface are not parallel, and a grinding space is formed between them. The first inclined surface of the wedge part 22 is provided with a grinding layer (not shown in the figure). The grinding layer can be a diamond abrasive layer with a mesh number of at least 1000. A cutting edge 21 is provided at the upper end of the wedge part 22. The cutting edge 21 is formed by welding with the wedge part 22 or is an integrally formed structure. The material of the cutting edge 21 can be a metal material. The upward side of it is the cutting edge part. A material blocking part 24 is fixedly connected to the outer wall of the driving part 23.

A spring 20 is wound around the periphery of the sliding columns 26. The two ends of the elastic force direction of the spring 20 elastically abut against the inner bottom wall of the sliding cavity 17 and the bottom surface of the wedge part 22 respectively, and the spring 20 gives the wedge part 22 the potential energy to move upward.

[0029] A lifting ring 19 is sleeved on the plurality of sliding columns 26 together. The lifting ring 19 is limitedly connected to the sliding columns 26 through the nuts 18, and a protruding part is fixedly connected to the upper end surface of the lifting ring 19. A short pin 29 is fixedly connected to the side wall of the sector plate 15. An arc-shaped groove 28 for the short pin 29 to be inserted is formed on the surface of the rotating seat 16. When the short pin 29 slides to the uppermost side of the arc-shaped groove 28, the top surface of the sector plate 15 is flush with the top surface of the rotating seat 16.

[0030] The working principle of the present invention: Start the cylinder 7. The cylinder rod of the cylinder 7 extends, and then drives the lifting plate 6 to move downward. When the lifting plate 6 moves downward, it will drive the mounting frame 10 to move downward, and then make the fixed seat 3 and the conveying cylinder 4 move downward until the fixed seat 3 is clamped in the collecting bin 2, and the longitudinal distance dimension between the opposite surfaces of the fixed seat 3 and the rotating seat 16 is the same as the longitudinal length dimension of the driving part 23, or in other words, the bottom surface of the driving part 23 is in sliding contact with the top surfaces of the rotating seat 16 and the sector plate 15. Feed is put into the hopper 5. Under the action of gravity, the feed falls from the hopper 5 into the conveying cylinder 4. The external electric control cabinet controls the servo motor 12 to start, so that the motor shaft of the servo motor 12 rotates a fixed number of turns. When the motor shaft of the servo motor 12 rotates, it will drive the spiral auger 13 to rotate, and then squeeze and convey the feed in the conveying cylinder 4 to the feed inlet 14, so that the feed can enter between the fixed seat 3 and the rotating seat 16 from the feed inlet 14, and the feed entering between the fixed seat 3 and the rotating seat 16 from the feed inlet 14 is evenly dispersed onto a plurality of sector plates 15 through the diversion and dispersion cone 27; Start the reduction motor 11. The reduction motor 11 drives the main shaft to rotate. The main shaft drives the rotating seat 16 to rotate, as Figure 5As shown, the rotation direction is clockwise from right to left. The fixed seat 3 is in a stationary state. Therefore, as the rotating seat 16 rotates, the wedge part 22 will rotate towards the driving part 23. During the rotation process, the second inclined surface on the driving part 23 can drive the feed on the rotating seat 16. Since the feed is cylindrical, during the driving process, the feed can change its position by itself, that is, the axial direction of the feed will automatically adjust to be perpendicular to the axial direction of the rotating seat 16, so that the feed can roll on the top surface of the rotating seat 16 and the top surface of the sector plate 15; When the feed is driven by the driving part 23 to the lowest position of the first inclined surface of the wedge part 22 (in the initial state, the spring 20 has an upward elastic abutting force on the bottom surface of the wedge part 22, so that the lowest position of the first inclined surface of the wedge part 22 is aligned with the top surface of the rotating seat 16), since the second inclined surface of the driving part 23 is not parallel to the first inclined surface of the wedge part 22, the feed will be driven into the grinding space enclosed by the first inclined surface and the second inclined surface. And as the rotating seat 16 rotates, the feed always stays in the grinding space. The lowest side of the second inclined surface will limit the feed, so that the feed will not fall onto the sector plate 15 (the sector plate 15 behind the rotating seat 16 in the rotation direction). The driving part 23 will continue to drive the feed to roll in the grinding space, and the feed will be rubbed by the grinding layer, and the harder surface of the feed will be ground off; During the grinding process, the driving part 23 has an extrusion force on the feed, and the feed will have a downward extrusion force on the wedge part 22, so that the wedge part 22 moves downward and compresses the spring 20, and the spring 20 stores elastic potential energy. When the feed is driven to the uppermost position of the first inclined surface of the wedge part 22, the feed will start to contact the cutting edge of the cutting blade 21. When the driving part 23 disengages from the wedge part 22, that is, at the moment when the first inclined surface and the second inclined surface disengage from each other, due to the release of the elastic potential energy of the spring 20, the cutting blade 21 will have an upward extrusion force on the feed, so that the feed is quickly extruded into the material retaining groove 25. The elastic potential energy of the spring 20 continues to be released, and further, the cutting blade 21 cuts the feed along the radial direction of the feed, dividing the feed into two parts or cutting it into several segments. It should be noted that the feed may not achieve the above effects during a single grinding and cutting. As the rotating seat 16 continues to rotate, the feed that has not achieved the grinding and cutting effects cannot fall through the sieve holes of the sector plate 15, so it will continue to be driven by the driving part 23 and undergo the next grinding and cutting, that is, the feed can achieve the required effects through repeated grinding and cutting; In addition, when the wedge-shaped portion 22 moves downward, it will cause the sliding column 26 to move downward, drive the lifting ring 19 to move downward, and further cause the protruding portion to move downward. Under the action of its own weight, the sector plate 15 will swing downward, and then disperse the feed in the middle area of the rotating seat 16 toward the radially outer side of the rotating seat 16, so as to ensure that the feed can be evenly distributed on the sector plate 15 and avoid the situation that when the driving portion 23 drives the feed into the grinding space, some feed cannot be ground due to the accumulation of feed. In addition, in this embodiment, the electric control cabinet controls the servo motor 12 to rotate at a fixed period and a fixed number of turns, so that the amount of feed fed between the fixed seat 3 and the rotating seat 16 each time is uniform, avoiding the occurrence of accumulation.
