Description

Technical Field

[0001] This utility model relates to the field of pellet mill technology, specifically to a feed particle size screening structure and a pellet mill. Background Technology

[0002] A pellet mill is a device that processes powdered feed into pelleted feed. Pellet mills are widely used in the livestock industry, especially in the poultry, pig, and cattle farming sectors. Pellet mills can convert powdered feed into pellets, making it easier to feed and transport, improving feed utilization. Pelleted feed is generally easier to digest and absorb than powdered feed, promoting animal growth. Pelleted feed can also reduce feed dusting and waste, improving the economic efficiency of feed. Furthermore, through pelleting, various nutrients and drugs can be added to meet the needs of different animals.

[0003] Material is fed into the pressing zone of the pellet mill through the feed hopper. Using the strong pressure of the pressure rollers, the material is squeezed and shaped through the holes of the die, thus compressing the material and forming pellets. Pelletization can reduce feed waste. Since the material contains different kinds of raw materials, and the particle size and shape of different kinds of raw materials are different, larger or irregular particles are prone to blockage or uneven flow during mixing and feeding, which leads to uneven distribution during pelleting. Smaller particles are easy to mix with larger particles, but if the particle size difference is too large, the mixing will be uneven, which can easily lead to inconsistent particle size of the final feed. Utility Model Content

[0004] The purpose of this invention is to provide a feed particle size screening structure and a pellet mill to solve the problem mentioned in the background art, where the material contains different kinds of raw materials with different particle sizes and shapes, which leads to uneven distribution during the pelleting process and thus inconsistent particle size of the final feed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feed particle size screening structure, including a discharge hood, the inner side of which is bonded to the outer side of a connecting pad, and the inner side of the connecting pad is fixed to the frame of a screen plate. A connecting plate is provided on the upper side of the screen plate, one end of which is fixed to the upper side of a semi-toothed disc via a central rod, and the semi-toothed disc is movably connected to the discharge hood via a bearing. The semi-toothed disc is in contact with a full-toothed disc, and the full-toothed disc is movably connected to the discharge hood via a bearing. A connecting block one, a connecting block two, and a connecting spring are provided on the inner side of the semi-toothed disc.

[0006] Preferably, one side of the first connecting block is fixed to the inner side of the half-tooth disc, and one side of the second connecting block is connected to the discharge hood.

[0007] Preferably, the two ends of the connecting spring are fixed to connecting block one and connecting block two respectively, and the lower side of the full-tooth disc is fixed to bevel gear one through the central rod.

[0008] Preferably, the first bevel gear is movably connected to the support plate via a bearing seat, and the first bevel gear is in contact with the second bevel gear.

[0009] Preferably, the second bevel gear is movably connected to the support plate via a bearing seat, and a transmission component is provided on one side of the second bevel gear.

[0010] Preferably, the transmission assembly includes a large gear plate, a small gear plate, and a toothed belt, wherein the bevel gear and the large gear plate of the transmission assembly are fixed to the output end of the drive motor.

[0011] Preferably, the drive motor is connected to the support plate, and the small gear of the transmission assembly is movably connected to the discharge hood through a bearing seat.

[0012] Preferably, a connecting frame is fixed to the side of the small gear plate of the transmission component near the connecting pad, and the connecting frame is pressed against the connecting pad.

[0013] Preferably, the connecting pad is made of deformable rubber material, a rubber plate is bonded to the lower side of the connecting plate, and the half-tooth disc and the full-tooth disc are meshed together.

[0014] A pellet mill includes a pellet mill body, on which the above-mentioned feed particle size screening structure is installed.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: when the feed pellets are discharged through the discharge hood, the drive motor is started at the same time. When the bevel gear two rotates, the connecting plate can push the discharged feed pellets to the left and right, which enhances the screening efficiency of the screen plate on the feed pellets, allowing the main body of the pellet mill to screen the feed pellets. When the large gear plate of the transmission component rotates, the connecting pad drives the screen plate to shake, making it less likely for feed pellets to get stuck on the surface of the screen plate, thus making it easier for the pellet mill to screen the feed pellets quickly.

A connecting plate 202 is provided on the upper side of the screen plate 2011, and one end of the connecting plate 202 is fixed to the upper side of the semi-toothed disc 203 through a central rod. The semi-toothed disc 203 is movably connected to the discharge hood 2 through a bearing. The semi-toothed disc 203 is in contact with the full-toothed disc 204, and the full-toothed disc 204... The semi-gear disc 203 is movably connected to the discharge hood 2 via bearings. Connecting block 1 2031, connecting block 2032, and connecting spring 2033 are provided on the inner side of the semi-gear disc 203. One side of connecting block 1 2031 is fixed to the inner side of the semi-gear disc 203, and one side of connecting block 2032 is connected to the discharge hood 2. Both ends of the connecting spring 2033 are fixed to connecting block 1 2031 and connecting block 2032 respectively. The lower side of the full gear disc 204 is fixed to bevel gear 205 via a central rod. 5. The bevel gear 205 is movably connected to the support plate 2091 via a bearing housing, and the bevel gear 206 is engaged with the first bevel gear 205. The second bevel gear 206 is movably connected to the support plate 2091 via a bearing housing, and a transmission assembly 207 is provided on one side of the second bevel gear 206. The transmission assembly 207 includes a large gear plate, a small gear plate, and a toothed belt. The large gear plate of the second bevel gear 206 and the transmission assembly 207 is fixed to the output end of the drive motor 209. The drive motor 209 is connected to the support plate 2091, and the transmission assembly 207... The small gear disc is movably connected to the discharge hood 2 via a bearing seat. A connecting frame 208 is fixed on the side of the small gear disc of the transmission assembly 207 near the connecting pad 201, and the connecting frame 208 is pressed against the connecting pad 201. The connecting pad 201 is made of deformable rubber material. A rubber plate is bonded to the lower side of the connecting plate 202. The half gear disc 203 and the full gear disc 204 are meshed together. The first bevel gear 205 and the second bevel gear 206 are meshed together. The large gear disc and the small gear disc of the transmission assembly 207 are meshed together with the toothed belt.

[0024] In specific implementation, according to Figures 1-5The material is fed into the pressing area of ​​the pellet mill body 1 through the feed hopper. The material is compressed and formed into pellets using the pressure rollers and mold of the pellet mill body 1. The feed pellets are then discharged through the discharge hood 2. Simultaneously, the drive motor 209 is started, causing its output to rotate the bevel gear 206 and the large gear disc of the transmission assembly 207. When the bevel gear 206 rotates, it meshes with the bevel gear 205, allowing the bevel gear 205 to rotate along with it, thus driving the large gear disc 207. 04 rotates, with the half-tooth disk 203 meshing with the full-tooth disk 204, causing the full-tooth disk 204 to drive the half-tooth disk 203 to rotate. At this time, the half-tooth disk 203 can drive the connecting plate 202 to rotate, and when the half-tooth disk 203 rotates, it can drive the connecting spring 2033 to extend through the connecting block 2031. When the full-tooth disk 204 and the half-tooth disk 203 disengage, the connecting spring 2033 retracts, causing the connecting spring 2033 to pull the half-tooth disk 203 back to its original position through the connecting block 2031, so that the half-tooth disk 203 can drive the connecting plate 202 to rotate again. 2. Reverse rotation causes the connecting plate 202 to push the discharged feed particles to the left and right, making it easier for the feed particles to be evenly spread on the upper side of the screen plate 2011, thus enhancing the screening efficiency of the screen plate 2011. At this time, small feed particles pass through the screen plate 2011 and fall down, while large feed particles slide off the upper side of the screen plate 2011, thereby allowing the pellet mill body 1 to screen the feed particles. When the large gear plate of the transmission component 207 rotates, the large and small gear plates of the transmission component 207 mesh with the toothed belt, causing the output end of the drive motor 209 to... The connecting frame 208 can be rotated by the transmission component 207. The connecting pad 201 is made of deformable rubber, and the connecting frame 208 and the connecting pad 201 are pressed together, so that when the connecting frame 208 rotates, it can push the connecting pad 201 upward, causing the connecting pad 201 to drive the screen plate 2011 to vibrate. At the same time, the rubber plate bonded to the lower side of the connecting plate 202 has a certain deformation capacity, so that the connecting plate 202 will not affect the vibration of the screen plate 2011, making it less likely for feed particles to get stuck on the surface of the screen plate 2011, thus making it easy for the pellet mill to quickly screen the feed particles.

[0025] The present invention provides a pellet mill, including a pellet mill body 1; the above-mentioned feed particle size screening structure is installed on the pellet mill body 1.

[0026] In summary, when the feed pellets are discharged through the discharge hood 2, the drive motor 209 is simultaneously started, causing the output end of the drive motor 209 to drive the bevel gear 206 and the large gear plate of the transmission assembly 207 to rotate. When the bevel gear 206 rotates, the connecting plate 202 pushes the discharged feed pellets to the left and right. At this time, the feed pellets with smaller diameters pass through the screen plate 2011 and fall down, while the feed pellets with larger diameters slide down from the upper side of the screen plate 2011. When the large gear plate of the transmission assembly 207 rotates, the connecting frame 208 can rotate and push the connecting pad 201, causing the connecting pad 201 to drive the screen plate 2011 to shake, making it less likely for feed pellets to get stuck on the surface of the screen plate 2011, thus making it easier for the pellet mill to quickly screen the feed pellets.
