[0001] This application relates to the field of feed pelleting technology, and more specifically, to a feed pelleting apparatus. Background Technology

[0002] In the field of feed production, feed pelleting equipment plays a key role in improving feed quality, facilitating storage and transportation, and promoting animal intake and digestion.

[0003] Chinese patent CN220573401U discloses a feed pellet mill. A second servo motor, a first screw, and a second limit rod drive a pressing assembly to descend, extruding material through the discharge hole of a fixed disc. The first servo motor and reciprocating screw rotate, driving a cutting assembly to move reciprocally. Multiple cutting blades simultaneously move reciprocally to cut the extruded material, achieving pelleting and preventing inconsistent particle lengths. The cut material falls onto a screen for screening, allowing smaller, non-compliant particles to pass through.

[0004] However, the discharge hole size of the fixed plate of the above-mentioned feed pellet mill is fixed, and the feed pellets produced have a single particle size, which cannot meet the diverse market demand. Different equipment needs to be replaced when producing feed with different particle sizes, which undoubtedly increases the equipment purchase cost. Summary of the Invention

[0005] The purpose of this application is to provide a feed pelleting device that can solve the technical problem that existing feed pelleting machines produce feed pellets with a single particle size, which cannot meet the diverse market demands, and that different equipment needs to be replaced when producing feed with different particle sizes, which undoubtedly increases the equipment procurement cost.

[0006] This application provides a feed pelleting device, including a support frame, an extrusion cylinder fixedly mounted on the support frame, a feed hopper at one top end of the extrusion cylinder, an extrusion assembly on the extrusion cylinder, a baffle fixedly mounted at the end of the extrusion cylinder away from the feed hopper, a material tray rotatably mounted on the side of the baffle away from the extrusion cylinder, a plurality of discharge areas equally spaced around the center of the material tray, discharge holes uniformly arranged in the discharge areas, the area of ​​the discharge holes in each discharge area being different, a through hole with the same area as the discharge area on the baffle, a locking assembly for locking the material tray on the baffle, and a pelletizing assembly for cutting the material extruded from the discharge holes into pellets on the support frame.

[0007] Furthermore, an annular limiting groove is provided on the side of the baffle near the material tray, and an annular connecting member adapted to the annular limiting groove is fixed on the material tray, and the annular connecting member is rotatably connected to the annular limiting groove.

[0008] Furthermore, the locking assembly includes a locking seat and a locking bolt. The locking seat is fixed to the baffle plate and has a threaded hole adapted to the locking bolt. The material tray has a plurality of positioning holes adapted to the locking bolt. The positioning holes correspond one-to-one with the discharge area. The locking bolt is threadedly connected to the locking seat through the threaded hole. The end of the locking bolt passes through the threaded hole and can be inserted into the positioning hole.

[0009] Furthermore, the extrusion assembly includes a rotating shaft, a helical blade, and a drive motor. The rotating shaft is rotatably disposed inside the extrusion cylinder, the helical blade is fixed on the rotating shaft, the drive motor is fixed on the bracket, and one end of the rotating shaft extends outside the extrusion cylinder and is connected to the output shaft of the drive motor.

[0010] Furthermore, the pelletizing assembly includes a pelletizing motor and a pelletizing blade. The pelletizing motor is fixed on the bracket, and the pelletizing blade is fixed on the output shaft of the pelletizing motor. The pelletizing blade abuts against the feed tray.

[0011] Furthermore, the support is provided with a pellet receiving hopper, which is located below the material tray.

[0029] like Figure 1-4As shown, this application provides a feed pelleting device including a support 1, an extrusion cylinder 2 fixedly mounted on the support 1, a feed hopper 3 at one top end of the extrusion cylinder 2, an extrusion assembly 4 mounted on the extrusion cylinder 2, a baffle 5 fixedly mounted at the end of the extrusion cylinder 2 away from the feed hopper 3, a feed pan 6 rotatably mounted on the side of the baffle 5 away from the extrusion cylinder 2, multiple discharge areas 61 evenly spaced around the center of the feed pan 6, discharge holes 62 evenly arranged in each discharge area 61, each discharge hole 62 having a different area, a through hole 51 with the same area as the discharge area 61 on the baffle 5, a locking assembly 7 for locking the feed pan 6 on the baffle 5, and a pelletizing assembly 8 for cutting the material extruded from the discharge holes 62 into pellets on the support 1. Specifically, the discharge areas 61 are arranged in a fan shape, and there are three discharge areas 61. In use, the appropriate discharge area 61 is selected by rotating the feed pan 6, aligning the selected discharge area 61 with the through hole 51 on the baffle 5, and then... The feeding tray 6 is locked by the locking component 7 to ensure that it will not rotate randomly during the pelleting process. The feed raw materials enter the extrusion cylinder 2 through the feed hopper 3. The extrusion component 4 applies pressure to the material in the extrusion cylinder 2, causing the material to move from the end of the extrusion cylinder 2 away from the feed hopper 3 and be extruded from the discharge hole 62 of the feeding tray 6. The material extruded from the discharge hole 62 is in the shape of a long strip. At this time, the pelleting component 8 starts to work. The pelleting component 8 cuts these long strips of material into pellets of a certain length through the cutting action, thus completing the entire pelleting process. The feed pelleting device of this application has multiple discharge areas 61 on the feeding tray 6, and the discharge hole 62 of each area is of different size. By rotating the feeding tray 6 to select different discharge areas 61 and locking the feeding tray 6 with the locking component 7, feed pellets of different sizes can be produced to meet the diverse market demands. Compared with the traditional pelleting device with a fixed discharge hole 62 size, different particle sizes can be produced without changing the equipment, reducing equipment purchase costs.

[0030] like Figure 2-4 As shown, an annular limiting groove 52 is provided on the side of the baffle 5 near the feed tray 6. An annular connector 63 adapted to the annular limiting groove 52 is fixed on the feed tray 6. The annular connector 63 is rotatably connected to the annular limiting groove 52. Through the tight cooperation between the annular limiting groove 52 and the annular connector 63, it can be ensured that the feed tray 6 rotates smoothly without shaking or deviating. Specifically, a first annular limiting protrusion is provided on the inner side of the end of the annular limiting groove 52 away from the baffle 5, and a second annular limiting protrusion is provided on the annular connector 63. The second annular limiting protrusion is rotatably set in the annular limiting groove 52. Through the cooperation between the first annular limiting protrusion and the second annular limiting protrusion, the feed tray 6 is prevented from separating from the baffle 5 during the operation of the feed pellet mill, ensuring the stability of the pelleting process.

[0031] like Figure 1-4As shown, the locking assembly 7 includes a locking seat 71 and a locking bolt 72. The locking seat 71 is fixed to the baffle 5 and has a threaded hole that matches the locking bolt 72. The feed tray 6 has multiple positioning holes 64 that match the locking bolt 72. Each positioning hole 64 corresponds to a discharge area 61. The locking bolt 72 is threadedly connected to the locking seat 71 through the threaded hole. The end of the locking bolt 72 passes through the threaded hole and can be inserted into the positioning hole 64. The operator rotates the feed tray 6 according to the required feed particle size, rotating the corresponding discharge area 61 to the position aligned with the through hole 51 on the baffle 5. Each positioning hole 64 on the tray 6 represents the locking position of a discharge area 61. After the discharge area 61 is determined, the locking bolt 72 is screwed into the threaded hole of the locking seat 71. Due to the action of the thread, the locking bolt 72 gradually moves towards the tray 6. Finally, the end of the locking bolt 72 passes through the threaded hole on the locking seat 71 and is inserted into the positioning hole 64 of the corresponding discharge area 61 on the tray 6. At this time, the tray 6 is fixed and can no longer rotate at will, thus ensuring that during the pelleting process, the material can only be squeezed out from the discharge hole 62 of the selected discharge area 61, ensuring the accuracy and consistency of the feed pellet size.

[0032] like Figure 2 As shown, the extrusion assembly 4 includes a rotating shaft 41, a spiral blade 42, and a drive motor 43. The rotating shaft 41 is rotatably mounted inside the extrusion cylinder 2, the spiral blade 42 is fixed on the rotating shaft 41, and the drive motor 43 is fixed on the bracket 1. One end of the rotating shaft 41 extends outside the extrusion cylinder 2 and is connected to the output shaft of the drive motor 43. The drive motor 43 drives the rotating shaft 41 to rotate, which in turn drives the spiral blade 42 to rotate. When the feed material enters the extrusion cylinder 2 from the feed hopper 3, the rotation of the spiral blade 42 pushes the material to move towards the feed tray 6 inside the extrusion cylinder 2, while simultaneously squeezing and pushing the material, so that the material is gradually compacted inside the extrusion cylinder 2 and finally extruded from the discharge hole 62 of the feed tray 6 to form a continuous strip of material, so that the subsequent pelletizing assembly 8 can cut it into granules. A sealing ring (not shown in the figure) is provided between the rotating shaft 41 and the extrusion cylinder 2 to prevent material from leaking from the gap between the rotating shaft 41 and the extrusion cylinder 2.

[0033] like Figure 1 and Figure 2 As shown, the pelletizing assembly 8 includes a pelletizing motor 81 and a pelletizing blade 82. The pelletizing motor 81 is fixed on the bracket 1, and the pelletizing blade 82 is fixed on the output shaft of the pelletizing motor 81. The pelletizing blade 82 abuts against the material tray 6. The pelletizing motor 81 drives the pelletizing blade 82 to rotate, thereby cutting the long strip of material extruded from the discharge hole 62 of the material tray 6 into pellets.

[0034] like Figure 1 and Figure 2As shown, the support 1 is equipped with a pellet hopper 9, which is located below the feed tray 6. The pellet hopper 9 can directly collect the feed pellets that are squeezed out from the discharge hole 62 of the feed tray 6 and cut by the pellet cutting component 8, so as to prevent the pellets from scattering around the equipment, making the pellet collection more concentrated and convenient, which is conducive to the subsequent unified sorting, packaging and other operations of the pellets, and maintaining the cleanliness of the working environment.

[0035] like Figure 1 and Figure 2 As shown, a baffle plate 10 is retractably installed at the discharge port of the pellet receiving hopper 9. The baffle plate 10 can flexibly control the discharge time and discharge amount of feed pellets in the pellet receiving hopper 9 as needed. When pellets need to be transferred or enter the next process, the baffle plate 10 can be pulled out to allow the pellets to flow out smoothly. When it is necessary to temporarily stop the discharge or control the discharge speed, the baffle plate 10 can be inserted to block the discharge of pellets, which facilitates material control by the operator according to the actual production situation.

[0036] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
