Description

Technical Field

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

[0002] When raising livestock, young livestock are generally fed with feed. For example, when feeding piglets, the feed usually needs to be crushed for feeding the piglets. The purpose of crushing is to prevent large particles and feed with a large surface hardness from causing indigestion in the piglets. The reason why the surface hardness of the feed is usually large is that during feed processing, the compression ratio of the pelletizer is high, which makes the surface hardness of the feed large, and it is difficult for the piglets to bite through the feed with a large surface hardness. In the existing technology, crushing equipment is used to crush large particles and feed with a large surface hardness for piglets to eat. However, the current crushing equipment usually splits the feed as a whole, and the surface hardness of the feed is still large. Due to the large degree of feed splitting, the feed may even become powdery, which may affect the digestive function of the piglets and affect the palatability of the feed. Therefore, there is a need for a crushing equipment that can process feed with a large surface hardness without causing the feed to be split to a large extent. Summary of the Invention

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

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] An automated feed crushing device for pig farming, comprising a machine base and:

[0006] A rotating seat rotatably connected to the top of the base, wherein the rotating seat is provided with a plurality of sector plates arranged in an array along its axial direction, wherein the rotating seat and the plurality of sector plates together form a disc-shaped structure, wherein the surface of the sector plates is provided with a plurality of sieve holes, and the top surface of the rotating seat is provided with a plurality of concave sliding cavities, wherein the sliding cavities are located between two adjacent sector plates;

[0007] A wedge-shaped portion is mounted in the sliding cavity and is free to slide up and down. The upward side of the wedge-shaped portion is provided with a first inclined surface. The rotating seat is provided with a reset unit. The reset unit gives the wedge-shaped portion potential energy for upward movement.

[0008] A lifting unit is 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 installed with a fixed seat, and the fixed seat is coaxial with the rotating seat;

[0009] The driving portion is fixed to the bottom surface of the fixing seat, and the bottom surface of the driving portion is provided with a second inclined surface that matches the first inclined surface, and the first inclined surface and the second inclined surface are not parallel.

[0010] 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-shaped portion, so that the feed is squeezed and rubbed by the second inclined surface on the driving part and the first inclined surface on the wedge-shaped portion, so that the surface of the feed is ground, and the surface with higher hardness of the feed is ground away. At the same time, the feed will not be split into multiple pieces, and the palatability of the feed will not be affected. It is convenient for feeding and digestion of suckling pigs.

[0011] Furthermore, the machine base is vertically rotatably connected to a main shaft, the rotating base is coaxially connected to the upper end of the main shaft, and the main shaft is driven to rotate by a reduction motor installed on the machine base.

[0012] Through the above technical solution, the main shaft is driven to rotate by the reduction motor, which in turn drives the rotating seat to rotate, so that the fixed seat and the rotating seat can generate relative rotational motion.

[0013] Furthermore, the lifting unit includes columns vertically installed on both sides of the machine base, the upper ends of the two columns are horizontally connected to a mounting plate, a cylinder is vertically installed on the top of the mounting plate, the cylinder drive is connected to the lifting plate, each end of the lifting plate is vertically connected to a guide column, the mounting plate is vertically embedded with a bushing, and the guide column is slidably inserted into the bushing.

[0014] 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 column slides in the bushing, which can produce a guiding effect on the vertical movement of the lifting plate.

[0015] Furthermore, the feeding unit includes a mounting bracket connected to the bottom of the lifting plate, a conveying cylinder is vertically installed at the bottom of the mounting bracket, the lower end of the conveying cylinder is connected to the top surface of the fixed seat, the top surface of the fixed seat is provided with a plurality of feed ports connected to the conveying cylinder, a servo motor is vertically installed on the mounting bracket, the servo motor drives a spiral auger, the spiral auger is coaxially installed in the conveying cylinder, and the conveying cylinder is provided with a hopper passing through its inner cavity.

[0016] Through the above technical solution, feed is put into the hopper, and the servo motor drives the spiral auger to rotate, so that the spiral auger can transport the feed through the feed port to between the fixed seat and the rotating seat, thereby realizing the feeding of the feed.

[0017] Furthermore, the first inclined surface of the wedge-shaped portion is provided with a grinding layer.

[0018] Through the above technical solution, the grinding layer generates a greater friction force on the feed surface, so that the feed surface can be ground off relatively smoothly.

[0019] Furthermore, a cutting edge is provided at the upper end of the wedge-shaped portion, and a material blocking structure is provided at the driving portion, and the material blocking structure is used in conjunction with the cutting edge.

[0020] Through the above technical solution, when the feed is driven by the driving part to the upper end of the first inclined surface, the driving part will disengage from the wedge-shaped part. At the moment of disengagement, 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. This will not cause the feed to be split into multiple parts and affect the palatability, but will also reduce the volume of the feed, making it easier for suckling pigs to digest and eat.

[0021] Furthermore, the material blocking structure includes a material blocking portion fixed to the outer wall of the driving portion, a material blocking groove is provided on a downward side of the material blocking portion, and an inner wall of the material blocking groove is inclined toward the driving portion.

[0022] Through the above technical solution, the cutting blade will squeeze the feed, so that the feed is squeezed into the material blocking trough. Since the inner wall of the material blocking trough is sloped, the feed continues to be squeezed by the cutting blade for a period of time after being stuck in the material blocking trough, so that the cutting blade can cut the feed.

[0023] Furthermore, the reset unit includes a sliding column that is vertically slidably inserted into the rotating seat, the upper end of the sliding column is fixed to the bottom surface of the wedge-shaped portion, and the lower end is threaded with a nut, and a spring is wrapped around the periphery of the sliding column, and the spring gives the wedge-shaped portion potential energy to move upward.

[0024] Through the above technical solution, the spring has an upward elastic supporting force on the wedge-shaped portion, so that after the wedge-shaped portion is separated from the driving portion, the spring will drive the wedge-shaped portion to move upward.

[0025] Furthermore, the fan-shaped plate is rotatably connected to the rotating seat at one end radially inward of the rotating seat, and the plurality of sliding columns are collectively provided with a lifting ring, which is connected to the sliding column by the nut, and a protrusion is fixed to the upper end surface of the lifting ring, and the protrusion is in contact with the bottom surface of the fan-shaped plate.

[0026] Through the above technical solution, when the driving part contacts 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 of the rotating seat, avoiding the feed delivered by the conveying cylinder between the rotating seat and the fixed seat from accumulating in the middle area of ​​the rotating seat.

[0027] 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 provided on the surface of the rotating seat.

[0028] 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.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 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 portion drives the feed to the first inclined surface of the wedge-shaped portion, so that the feed is squeezed and rubbed by the second inclined surface of the driving portion and the first inclined surface of the wedge-shaped portion, so that the surface of the feed is ground, thereby grinding away the surface of the feed with greater hardness. At the same time, the feed will not be split into multiple pieces, and the palatability of the feed will not be affected. The feed is easy to feed and digest by suckling pigs.

[0031] 2. In the present invention, when the feed is driven by the driving portion to the upper end of the first inclined surface, the driving portion will disengage from the wedge-shaped portion. At the moment of disengagement, the cutting blade will squeeze the feed, causing the feed to be squeezed into the material retaining structure. Driven by the elastic supporting force of the wedge-shaped portion by the reset unit, the cutting blade will move upward and cut the feed stuck in the material retaining structure, so that the feed is cut and large particles of feed can be separated. This will not cause the feed to be split into multiple parts and affect palatability, but will also reduce the volume of the feed, making it easier for the suckling pig to digest and eat.

[0032] 3. In the present invention, when the driving portion contacts the wedge-shaped portion, it will generate downward pressure on the wedge-shaped portion, so that the wedge-shaped portion 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 of the rotating seat, avoiding the feed delivered by the conveying cylinder to the space between the rotating seat and the fixed seat from accumulating in the middle area of ​​the rotating seat.

[0048] Multiple sliding columns 26 are collectively fitted with a lifting ring 19, which is limitedly connected to the sliding column 26 by a nut 18, and a protrusion is fixed to the upper end surface of the lifting ring 19. A short pin 29 is fixed to the side wall of the sector plate 15, and an arc-shaped groove 28 for the short pin 29 to be inserted is opened 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.

[0049] Working principle of the present invention:

[0050] 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 drives the mounting frame 10 to move downward, and then the fixed seat 3 and the conveying cylinder 4 move downward until the fixed seat 3 is engaged in the collecting bin 2, and the longitudinal distance between the opposite surfaces of the fixed seat 3 and the rotating seat 16 is consistent with the longitudinal length of the driving portion 23, or in other words, the bottom surface of the driving portion 23 is in sliding contact with the rotating seat 16 and the top surface of the fan-shaped plate 15, and the feed is put into the hopper 5. Under the action of gravity, the feed is fed into the hopper 5. The hopper 5 falls into the conveying cylinder 4, and the external electric control cabinet controls the servo motor 12 to start, causing the motor shaft of the servo motor 12 to rotate a fixed number of circles. When the motor shaft of the servo motor 12 rotates, it will drive the spiral auger 13 to rotate, thereby squeezing 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 through the feed inlet 14, and then be evenly dispersed onto the multiple sector plates 15 by the guide dispersion cone 27.

[0051] Start the reduction motor 11, the reduction motor 11 drives the main shaft to rotate, and the main shaft drives the rotating seat 16 to rotate, such as Figure 5 As shown, the rotation direction is clockwise from right to left, and the fixed seat 3 is in a stationary state. Therefore, as the rotating seat 16 rotates, the wedge-shaped portion 22 will rotate in the direction of the driving portion 23. During the rotation process, the second inclined surface on the driving portion 23 can drive the feed on the rotating seat 16. Since the feed is cylindrical, the feed can change its position during the driving process, 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;

[0052] When the feed is driven by the driving portion 23 to the lowest point of the first inclined surface of the wedge-shaped portion 22 (in the initial state, the spring 20 exerts an upward elastic force on the bottom surface of the wedge-shaped portion 22, so that the lowest point of the first inclined surface of the wedge-shaped portion 22 is aligned with the top surface of the rotating seat 16), since the second inclined surface of the driving portion 23 is not parallel to the first inclined surface of the wedge-shaped portion 22, the feed will be driven into the grinding space surrounded by the first and second inclined surfaces, and as the rotating seat 16 rotates, the feed always stays in the grinding space, and the lowest point 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 on the rear side of the rotating seat 16 in the rotation direction), and the driving portion 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;

[0053] During the grinding process, the driving portion 23 exerts an extrusion force on the feed, and the feed will exert a downward extrusion force on the wedge-shaped portion 22, causing the wedge-shaped portion 22 to move downward and compress the spring 20. The spring 20 accumulates elastic potential energy, and when the feed is driven to the uppermost side of the first inclined surface of the wedge-shaped portion 22, the feed will begin to contact the edge of the cutting edge 21. When the driving portion 23 is out of contact with the wedge-shaped portion 22, that is, the moment the first inclined surface is out of contact with the second inclined surface, the elastic potential energy of the spring 20 is released, causing the cutting edge 21 to exert an upward extrusion force on the feed, causing the feed to be ground. The feed is quickly squeezed into the retaining groove 25, and the elastic potential energy of the spring 20 continues to be released, thereby causing the cutting blade 21 to cut the feed along the radial direction of the feed, dividing the feed into two, or cutting it into several segments. It should be noted that the feed may not achieve the above-mentioned effect in a single grinding and cutting. As the rotating seat 16 continues to rotate, the feed that has not achieved the grinding and cutting effect 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 desired effect by repeatedly grinding and cutting.

[0054] In addition, when the wedge-shaped portion 22 moves downward, it will cause the sliding column 26 to move downward, and drive the lifting ring 19 to move downward, thereby causing the protrusion to move downward. The sector plate 15 will swing downward under the action of its own weight, thereby dispersing the feed in the middle area of ​​the rotating seat 16 toward the radial outside of the rotating seat 16 to ensure that the feed can be evenly distributed on the sector plate 15, and avoid the accumulation of feed when the driving portion 23 drives the feed into the grinding space, resulting in some feed not being able to be ground. In addition, the electric control cabinet in this embodiment controls the servo motor 12 to rotate according to a fixed period and a fixed number of turns, so that the amount of feed delivered between the fixed seat 3 and the rotating seat 16 each time is uniform, avoiding accumulation.
