Description

Technical Field

[0001] This utility model belongs to the field of feed production technology, specifically a feed extrusion pelleting device. Background Technology

[0002] Feed is a general term for the food of all domesticated animals. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed ingredients such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives, so that livestock and poultry can eat a comprehensive diet.

[0003] Feed is made by a feed pellet mill through rotary extrusion and cutting of crushed materials such as corn, soybean meal, straw, grass, and rice husks. It is used for subsequent animal feeding, facilitates storage and transportation, and improves feed utilization.

[0004] While existing feed pellet mills can extrude feed raw materials into pellets, after prolonged use, the pelleting efficiency will decrease, or even stop. The reason for this is that the gap between the pressure roller and the ring die increases due to wear. Only by replacing the pressure roller can the machine work again. This is not only time-consuming and labor-intensive, but also increases the user's operating costs. Utility Model Content

[0005] To address the problem that existing feed pellet mills suffer from significant wear on the pressure rollers after prolonged use, requiring replacement which is time-consuming, labor-intensive, and costly, this invention provides a feed extrusion pelleting device.

[0006] This utility model is achieved through the following technical solution:

[0007] A feed extrusion pelleting device includes a base, a worktable mounted on the base, a first motor mounted on the worktable, and a pressing chamber. The output shaft of the first motor is connected to a pressing roller device that is rotatably connected to the bottom of the inner side of the pressing chamber.

[0008] The pressure roller device includes a fixed frame. The side wall of the fixed frame has several evenly distributed polygonal holes. Corresponding connecting rods are slidably connected and installed in the polygonal holes. A retainer is connected and installed at the outer end of the connecting rod. A pressure roller tangent to the inner wall of the pressing chamber is rotatably connected and installed on the retainer. A micro-moving block with an inclined surface is connected and installed at the other end of the connecting rod. A spring block that can elastically support the connecting rod inward is provided on the inner wall of the fixed frame. Several guide posts are connected and installed at the bottom of the fixed frame. A micro-moving plate that slides and cooperates with the inclined surface of the micro-moving block is slidably connected and installed on the guide posts. A threaded hole is provided in the center of the micro-moving plate. A screw that abuts against the inner bottom surface of the fixed frame is threaded and installed in the threaded hole.

[0009] A further improvement of this utility model is that a flange seat is connected and installed at the bottom of the pressing chamber and sleeved on the output shaft of the first motor. A turntable is rotatably connected and installed on the outer wall of the flange seat, which is rotatably connected to the pressing chamber and the worktable. An internal gear is provided at the bottom of the turntable. A second motor is connected and installed on one side of the bottom of the worktable. An external gear that meshes with the internal gear is installed through the output shaft of the second motor and drives the worktable. A scraper that slides tangentially to the outer edge of the pressing chamber is connected and installed on the outer edge of the turntable.

[0010] A further improvement of this utility model is that the side wall of the worktable is provided with an annular groove that slides and nests with the edge of the turntable.

[0011] A further improvement of this utility model is that a conical cover plate is connected and installed on the upper side of the fixed frame.

[0012] A further improvement of this utility model is that the scraper is provided with a cutting edge on the side near the pressing chamber.

[0013] A further improvement of this utility model is that the base is provided with several ventilation holes.

[0014] A further improvement of this utility model is that an opening is provided on the side wall of the workbench, and a baffle that is tangent to the upper surface of the turntable is connected and installed on one side of the opening.

[0015] A further improvement of this invention is that a discharge chute is provided at the lower edge of the opening to guide the feed.

[0016] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0017] When feed ingredients are placed into the pressing chamber, the first motor drives the pressure roller to roll on the inner surface of the pressing chamber, extruding the feed ingredients through the holes in the pressing chamber to produce pellet feed. After prolonged use, if the pellet production efficiency decreases or even stops, the screw can be rotated inwards. The screw will press against the bottom of the pressing chamber, causing the micro-motion plate to slide upwards along the guide post. The micro-motion plate will slide relative to the micro-motion block, squeezing the micro-motion block outwards. Then, through the connecting rod, the gap between the pressure roller and the inner wall of the pressing chamber will be restored to normal, allowing the device to continue producing pellets. This device adjusts the gap between the pressure roller and the pressing chamber through micro-motion adjustment, avoiding the time-consuming and laborious process of disassembling and replacing the pressure roller, reducing user costs, and improving production efficiency.

Detailed Implementation

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] like Figures 1-4 As shown, a feed extrusion pelleting device includes a base 1, a worktable 2 connected and installed on the base 1, a first motor 4 connected and installed on the worktable 2, and a pressing chamber 3 connected and installed on the worktable 2. The output shaft of the first motor 4 passes through the worktable 2 and is connected to a pressing roller device 8 that is rotatably connected to the bottom of the inner side of the pressing chamber 3 through a thrust bearing.

[0026] The pressure roller device 8 includes a fixed frame 15. Eight polygonal holes 16 are provided on the periphery of the fixed frame 15. The polygonal holes 16 can be quadrilateral or pentagonal, etc. A connecting rod 17 is slidably connected to each polygonal hole 16. A retainer 18 is connected to the outer end of the connecting rod 17. A pressure roller 19, tangent to the inner wall of the pressing chamber 3, is rotatably connected to the retainer 18. The surface of the pressure roller 19 has textured protrusions to increase pressure and make the material extrusion smoother. A micro-moving block 20 with an inclined surface is connected to the other end of the connecting rod 17. The inner wall of the fixed frame 15... The upper part is provided with a spring block 21 that can elastically support the connecting rod 17 inward. The spring block 21 can be rubber or spring. The connecting rod 17 is provided with a boss 22 that provides an elastic fulcrum for the spring block 21. The bottom of the fixed frame 15 is connected and installed with four vertically arranged guide posts 23. The guide posts 23 are slidably connected and installed with micro-movement plates 24 that slide with the inclined surface of the micro-movement block 20. The micro-movement plate 24 is an octahedral frustum corresponding to the eight micro-movement blocks 20. The center of the micro-movement plate 24 is provided with a threaded hole 25. The threaded hole 25 is internally threaded and installed with a screw 26 that abuts against the fixed frame 15.

[0027] When feed ingredients are placed into the pressing chamber 3, the first motor 4 drives the fixed frame 15 to rotate, which in turn causes the pressure roller 19 to roll on the inner surface of the pressing chamber 3, extruding the feed ingredients through the holes in the pressing chamber 3 to produce pellet feed. After prolonged use, if the pellet production efficiency decreases or even stops, the screw 26 can be rotated to screw it into the threaded hole 25. The screw 26 will press against the inner bottom surface of the fixed frame 15, causing the micro-motion plate 24 to slide upward along the guide post 23. The micro-motion plate 24 will slide relative to the micro-motion block 20, squeezing the micro-motion block 20 to slide outward. Then, the connecting rod 17 restores the normal gap between the pressure roller 19 and the inner wall of the pressing chamber 3, allowing the device to continue producing pellets. This device adjusts the gap between the pressure roller 19 and the pressing chamber 3 through micro-motion adjustment, avoiding the time-consuming and laborious problem of disassembling and replacing the pressure roller due to wear. The adjustment is convenient and quick, reducing the user's operating costs and improving production efficiency.

[0028] It should be noted that the spring block 21 can keep the connecting rod 17 fixed and prevent the connecting rod 17 from driving the pressure roller 19 to move. The position of the pressure roller 19 can only be changed when the micro-adjustment plate 24 is adjusted. In addition, the outer diameter of the retainer 18 should be smaller than the diameter of the pressure roller 19 to prevent the retainer 18 from contacting the inner wall of the pressure chamber 3 and affecting production. Due to the elasticity of the spring block 21 and the reaction force of the material on the pressure roller 19 during operation, the screw 26 and the threaded hole 25 are subjected to a large force, so that the screw 26 can tightly bite the threaded hole 25 and avoid loosening that would affect production.

[0029] The pressing chamber 3 has a flange seat 7 mounted on the output shaft of the first motor 4 at its bottom. A turntable 9 is rotatably mounted on the outer wall of the flange seat 7. The upper and lower sides of the turntable 9 are rotatably connected to the pressing chamber 3 and the worktable 2 via thrust bearings, allowing the turntable 9 to rotate freely between the worktable 2 and the pressing chamber 3. An internal gear 10 is located at the bottom of the turntable 9. A second motor 11 is mounted on one side of the bottom of the worktable 2. The output shaft of the second motor 11 passes through the worktable 2 and is connected to an external gear 13 that meshes with the internal gear 10. A scraper 14 is mounted on the outer edge of the turntable 9 and slides tangentially to the outer edge of the pressing chamber 3. The second motor 11 drives the external gear 13 to rotate, which in turn drives the internal gear 10 to rotate, thus rotating the turntable 9. The scraper 14 connected to the turntable 9 can cut the extruded feed pellets from the surface of the pressing chamber 3, ensuring that the feed pellets maintain a consistent length, which is beneficial for improving the quality of feed production. The rotating turntable 9 can also transport the pellets for easy collection.

[0030] The workbench 2 has an annular groove 27 on its side wall that slides and nests with the edge of the turntable 9, allowing the outer edge of the turntable 9 to rotate within the annular groove 27. This prevents feed particles from getting stuck in the gap between the side wall of the workbench 2 and the turntable due to gravity, thus affecting the rotation of the turntable.

[0031] A conical cover plate 28 is connected and installed on the upper side of the fixed frame 15. The conical cover plate 28 can disperse the feed raw materials poured into the pressing chamber 3 to the surrounding area, so that the feed raw materials can be squeezed out of the pressing chamber by the pressure roller 19. This can reduce the residue of feed raw materials, prevent the residual feed from deteriorating and affecting the quality, improve the utilization rate of feed, and also prevent the feed raw materials from falling into the fixed frame 15, ensuring that the internal micro-adjustment is not affected by dust. The rotating conical cover plate 28 can also make the raw materials rotate, preventing the raw materials from getting stuck and not falling.

[0032] It should be noted that the surface of the conical cover plate 28 is relatively smooth, and the friction between it and the raw materials is small, so it will not affect the normal operation of the first motor 4.

[0033] The scraper 14 has a cutting edge 29 on the side near the pressing chamber 3. The cutting edge 29 can quickly cut the particles, reduce the resistance of the shearing motion, reduce the workload of the second motor 11, improve the service life of the second motor, and reduce power consumption.

[0034] The base 1 is provided with several ventilation holes 30. The ventilation holes 30 can dissipate heat for the internal motor, prevent the internal motor from operating in a high-temperature environment and reduce the risk, and can also reduce weight, increase structural strength and improve the stability of the device.

[0035] The workbench 2 has an opening 31 on its side wall, and a baffle 32 is connected and installed on one side of the opening 31, which is tangential to the upper surface of the turntable 9. When the pellets fall onto the turntable 9, the moving turntable 9 will cause the feed pellets to rotate. When the rotation reaches the opening 31, the baffle 32 will block the feed pellets, allowing them to rotate out from the opening 31, thus completing the collection of the feed pellets.

[0036] It should be noted that the baffle 32 should be set on the side of the turntable 9 that is away from the opening 31, so that the feed pellets can be blocked at the opening 31 and rolled out from the opening 31 for easy collection.

[0037] The lower edge of the opening 31 is provided with a discharge chute 33 that guides the feed. The discharge chute 33 allows the pelleted feed coming out of the opening 31 to slide into the container, preventing the pelleted feed from breaking after traveling a high vertical distance, which would result in more fragments and affect the quality of the pelleted feed.

[0038] In operation, first start the first motor 4 and the second motor 11 to get all parts of the device running. Then add the feed ingredients to be processed to prevent excessive load during startup, which could overload the motors and affect their lifespan. The added feed ingredients are guided by the conical cover plate 28 to disperse and fall between the pressure roller 19 and the pressing chamber 3. The first motor 4 drives the fixed frame 15 to rotate, and the fixed frame 15 drives the pressure roller 19 to roll on the inner wall of the pressing chamber 3, squeezing the feed ingredients out of the holes on the inner wall of the pressing chamber 3 to form feed pellets. The second motor 11 drives the turntable 9 to rotate, and the scraper 14 on the turntable 9 scrapes the feed pellets off the outer wall of the pressing chamber 3 to obtain feed pellets of uniform size and length. The baffle 32 on one side of the opening 31 of the workbench 2 can prevent the rotation of the feed pellets. The feed pellets rotating on the disc 9 are blocked at the opening 31, facilitating their collection. The pellets then slide from the discharge chute 33 into the collection container, reducing pellet breakage. After a certain period of use, the pressure roller 19 will wear out, causing the gap between it and the pressing chamber 3 to widen. This results in insufficient pressure on the feed raw materials, reducing the production efficiency of the feed pellets. To address this, the conical cover plate 28 needs to be removed, and the screw 26 needs to be screwed into the threaded hole 25 of the micro-motion plate 24. This causes the micro-motion plate 24 to slide outward along the guide post 23, which in turn drives the micro-motion block 20 to slide outward, restoring the gap between the pressure roller 19 and the pressing chamber 3. This avoids the time-consuming and labor-intensive process of replacing the pressure roller 19 or even the pressing chamber 3, effectively improving production efficiency and reducing operating costs.

[0039] It should be noted that both the first motor 4 and the second motor 11 are powerful three-phase motors, ensuring sufficient output power. In order to avoid accidents such as overload, complete circuit protection facilities are also required, such as circuit breakers, overload protectors, fuses and emergency stop devices, to ensure production safety. To improve the automation of production, a material conveying mechanism can be added to convey raw materials into the pressing chamber 3, reducing the intensity of manual labor. A screening mechanism can also be set up to screen the produced feed pellets, screen out the broken feed pellets, and reprocess them to ensure the quality of the feed pellets. The pressure roller 19 still needs to be replaced regularly. This device aims to extend the service life of the pressure roller 19.
