Description

Technical Field

[0001] This utility model relates to the technical field of feeding equipment, and in particular to a multi-axis auger feeder. Background Technology

[0002] Feeding equipment typically uses augers or conveyor belts for the feeding process of processing equipment. To reduce manual labor, a storage bin is usually installed at the bottom of the feeding equipment. Large transfer equipment such as forklifts are used to deliver materials into the storage bin, enabling continuous feeding of the processing equipment for a period of time, greatly saving manpower (see appendix). Figure 10 ).

[0003] When some materials are in powder form or are relatively moist, they will clump together after accumulating in the storage silo for a period of time, causing the bottom of the silo to become unsupported and interrupting the feeding process, which seriously affects the efficiency of the processing equipment. The existing solution is to manually tap the side wall of the storage silo or use a special agitator to stir the material inside the silo, so that the clump of material inside the silo will disperse and fall, allowing the feeding operation to continue; for example, Chinese Patent: CN120036406A - A feeding device for producing compressed candy.

[0004] However, the above methods can only be applied to small storage silos. For large storage silos, when using a forklift to load materials, a large amount of material falling down can easily bend the agitator, thus affecting the normal use of the equipment.

[0005] Therefore, a feeding device that can solve the above problems is needed. Utility Model Content

[0006] The purpose of this invention is to solve the above problems and provide a multi-axis auger feeder.

[0007] The technical solution of this utility model is: a multi-axis auger feeder, including a feeding auger and a storage bin, wherein the feeding auger is inclined; the storage bin includes a hopper, a dispersing conveyor mechanism and a discharge box connected in sequence from top to bottom, and the discharge box is connected to the feeding auger; after the material is put into the storage bin, it enters the dispersing conveyor mechanism through the hopper, and the material is dispersed and falls into the discharge box; the material is dispersed before feeding to avoid the material from caking in the storage bin and affecting the feeding efficiency.

[0008] The dispersing and conveying mechanism includes a housing and dispersing shafts; the housing is square and open at the top; the top of the housing is connected to the hopper; several dispersing shafts are arranged side by side inside the housing; the ends of the dispersing shafts are connected to drive motors, which are installed outside the housing; several V-shaped material accumulation troughs are arranged side by side at the bottom of the housing, and the dispersing shafts are correspondingly positioned in the material accumulation troughs; the dispersing shafts and material accumulation troughs correspond one-to-one; the hopper is connected to the top of the housing; when the material falls, it falls into the material accumulation trough, and the corresponding dispersing shafts disperse the material in the material accumulation trough.

[0009] The bottom of the shell is also provided with a strip-shaped discharge port, which is matched with the material accumulation trough; the discharge port is connected to the discharge box.

[0010] Several external bearings are installed on the outside of the housing, and the end of the dispersing shaft passes through the housing and mates with the external bearings. This prevents materials or dust from falling into the bearings, affecting their normal operation, and thus extending the service life of the equipment.

[0011] Preferably, the bottom side of the housing is provided with an arc-shaped plate, the size of which matches the size of the dispersing shaft. This avoids dead corners at the inner bottom edge of the housing that could lead to material accumulation.

[0012] Preferably, the dispersing shaft includes a shaft body and a spiral scraper disposed on the outer side of the shaft body; the overall length of the spiral scraper matches the length of the material accumulation trough. When the shaft body rotates, the spiral scraper can push the material in the material accumulation trough towards the discharge port; at the same time, it can scrape the material above the dispersing shaft to prevent the material from caking.

[0013] Furthermore, the discharge port is located in the middle of the bottom surface of the housing, and the length direction of the discharge port is perpendicular to the direction of the dispersing shaft.

[0014] Each dispersing shaft is equipped with two spiral scrapers, which are symmetrically arranged along the center face of the discharge port. When the dispersing shaft rotates, the two opposing spiral scrapers can push the material on both sides of the discharge port toward the middle discharge port, thereby continuously feeding material to the auger. In addition, shortening the overall length of each spiral scraper section can reduce the degree of compression of the material by the spiral scraper during conveying and prevent the material from clumping.

[0015] Furthermore, the spiral scrapers on the adjacent dispersing shafts rotate in opposite directions, and the adjacent dispersing shafts also rotate in opposite directions. The dispersing shafts rotating in opposite directions can crush the material clumps between the dispersing shafts, thereby preventing the material clumps from moving to the discharge port and clogging it.

[0016] Preferably, the storage silo further includes a fixing frame, with the hopper fixedly mounted on top of the fixing frame. The fixing frame lifts the entire storage silo, ensuring the stable operation of the silo's dispersing and conveying mechanism, while also providing sufficient space for the installation of the bottom feeding auger.

[0017] Preferably, the feeding auger includes an auger conveyor shaft, a feeding housing, and a top cover; the feeding housing is U-shaped in general, including an arc-shaped bottom plate and vertically arranged side plates, and the outer diameter of the auger conveyor shaft is fitted with the inner wall of the arc-shaped bottom plate; both ends of the auger conveyor shaft are rotatably connected to the feeding housing; the top cover is fastened to the top of the side plates of the feeding housing; the arc-shaped bottom plate cooperates with the auger conveyor shaft to transport materials along the arc-shaped bottom plate.

[0018] A discharge cylinder is provided at one end of the feeding shell, and the discharge cylinder is connected to the feeding shell; a feed inlet is provided at the end of the top cover away from the discharge cylinder, and the feed inlet is connected to the discharge box. After the material enters from the feed inlet of the feeding auger, it is conveyed to the discharge cylinder by the auger conveyor shaft for the final feeding step.

[0019] An external bearing is installed at the end of the feeding housing. The end of the auger conveyor shaft passes through the feeding housing and engages with the external bearing. This prevents materials or dust from falling into the bearing, affecting its normal operation, and thus extending the service life of the equipment.

[0020] A sprocket is installed at one end of the auger conveyor shaft near the feed inlet, and the sprocket is located outside the feeding housing. A feeding motor is also installed on the outside of the feeding housing, and the feeding motor and the auger conveyor shaft are driven by a chain.

[0021] Furthermore, the discharge box includes a horizontal connecting flange A and an inclined connecting flange B; connecting flange A is connected to the discharge port of the housing, and connecting flange B is connected to the inlet of the feeding auger. Using the discharge box to connect the inlet of the feeding auger and the discharge port of the dispersing conveyor prevents material dust from scattering and affecting the working environment.

[0022] The beneficial effects of this utility model are as follows: The multi-axis auger feeder of this utility model has the following advantages:

[0023] 1. In this utility model, a dispersing and conveying mechanism is set in the storage bin. The material in the hopper will fall into the accumulation trough of the dispersing and conveying mechanism. After the dispersing shaft disperses the material, the material falls into the feeding auger through the discharge port. This can avoid a large amount of material being filled at once, which would cause caking and affect the feeding progress.

[0024] 2. The dispersing shaft of this utility model is equipped with two symmetrical spiral scrapers, so that when the shaft rotates, the two spiral scrapers will provide thrust to the material in different directions, thereby pushing the material on both sides toward the discharge port in the middle of the shell and avoiding the accumulation of material in the storage bin.

[0025] 3. The dispersing shaft of this utility model shortens the overall length of each section of the spiral scraper, which can reduce the degree of compression of the material by the spiral scraper during conveying and prevent the material from clumping. Attached Figure Description

[0038] Example 1: See Figure 1-9 A multi-axis auger feeder includes a feeding auger 2 and a storage bin 1. The feeding auger 2 is inclined. The storage bin 1 includes a hopper 11, a dispersing conveyor mechanism 12, and a discharge box 13 connected in sequence. The discharge box 13 is connected to the feeding auger 2. After the material is put into the storage bin 1, it enters the dispersing conveyor mechanism 12 through the hopper 11. After the material is dispersed, it falls into the discharge box 13. The material is dispersed before feeding to avoid the material from caking in the storage bin 1 and affecting the feeding efficiency.

[0039] The dispersing and conveying mechanism 12 includes a housing 121 and dispersing shafts 122. The housing 121 is square and has an open top. The top of the housing 121 is connected to the hopper 11. Several dispersing shafts 122 are arranged side by side inside the housing 121. A drive motor 124 is connected to the end of the dispersing shaft 122, and the drive motor 124 is installed outside the housing 121. Several V-shaped material collection grooves 123 are arranged side by side at the bottom of the housing 121, and the dispersing shafts 122 are correspondingly arranged in the material collection grooves 123. The dispersing shafts 122 and the material collection grooves 123 are one-to-one. The hopper 11 is connected to the top of the housing 121. When the material falls, it falls into the material collection groove 123, and the corresponding dispersing shaft 122 disperses the material in the material collection groove 123.

[0040] The bottom of the housing 121 is also provided with a strip-shaped discharge port 1211, which cooperates with the material accumulation trough 123; the discharge port 1211 is connected to the discharge box 13.

[0041] The outer bottom surface of the shell 121 is provided with several stiffening plates 1213, all of which are arranged parallel to the discharge port 1211. This increases the strength of the bottom surface of the shell 121, thereby allowing the storage bin 1 to hold more material.

[0042] Several external bearings 3 are provided on the outside of the housing 121. The end of the dispersing shaft 122 passes through the housing 121 and engages with the external bearings 3. This prevents materials or dust from falling into the bearings and affecting their normal operation, thereby extending the service life of the equipment.

[0043] An arc-shaped plate 1212 is provided on the bottom side of the housing 121, the size of which matches the size of the dispersing shaft 122. This prevents dead corners from forming on the inner bottom edge of the housing 121, which could lead to material accumulation.

[0044] The dispersing shaft 122 includes a shaft body 1221 and a spiral scraper 1222 disposed on the outer side of the shaft body 1221; the overall length of the spiral scraper 1222 matches the length of the material accumulation trough 123. When the shaft body 1221 rotates, the spiral scraper 1222 can push the material in the material accumulation trough 123 toward the discharge port 1211; at the same time, it can scrape the material above the dispersing shaft 122 to prevent the material from caking.

[0045] The discharge port 1211 is located in the middle of the bottom surface of the housing 121, and the length direction of the discharge port 1211 is perpendicular to the direction of the dispersing shaft 122.

[0046] Each dispersing shaft 122 is equipped with two spiral scrapers 1222, which are symmetrically arranged along the center face of the discharge port 1211. When the dispersing shaft 122 rotates, the two opposing spiral scrapers 1222 can push the material on both sides of the discharge port 1211 toward the middle discharge port 1211, thereby continuously feeding material to the feeding auger 2; in addition, shortening the overall length of each spiral scraper 1222 can reduce the degree of compression of the material by the spiral scraper 1222 during conveying, and prevent the material from clumping.

[0047] The spiral scrapers 1222 on adjacent dispersing shafts 122 rotate in opposite directions, and the adjacent dispersing shafts 122 rotate in opposite directions. The dispersing shafts 122 with opposite rotation directions can crush the material clumps between the dispersing shafts 122, thereby preventing the material clumps from moving to the discharge port 1211 and blocking the discharge port 1211.

[0048] The storage bin 1 also includes a fixing frame 14, with the hopper 11 fixedly mounted on top of the fixing frame 14. The fixing frame 14 lifts the storage bin 1 as a whole, ensuring the stable operation of the dispersing and conveying mechanism 12 of the storage bin 1, while also providing sufficient space for the installation of the bottom feeding auger 2.

[0049] The feeding auger 2 includes an auger conveyor shaft 21, a feeding housing 22, and a top cover 23. The feeding housing 22 is U-shaped and includes an arc-shaped bottom plate and vertically arranged side plates 222. The outer diameter of the auger conveyor shaft 21 is fitted with the inner wall of the arc-shaped bottom plate 221. Both ends of the auger conveyor shaft 21 are rotatably connected to the feeding housing 22. The top cover 23 is fastened to the top of the side plates 222 of the feeding housing 22. The arc-shaped bottom plate 221 is fitted with the auger conveyor shaft 21, which can transport materials along the arc-shaped bottom plate 221.

[0050] A discharge cylinder 223 is provided at one end of the feeding housing 22, and the discharge cylinder 223 is connected to the feeding housing 22. A feed inlet 231 is provided at the end of the top cover 23 away from the discharge cylinder 223, and the feed inlet 231 is connected to the discharge box 13. After the material enters from the feed inlet 231 of the feeding auger 2, it is conveyed to the discharge cylinder 223 by the auger conveyor shaft 21 for the final feeding step.

[0051] An external bearing 3 is installed at the end of the feeding housing 22. The end of the auger conveyor shaft 21 passes through the feeding housing 22 and engages with the external bearing 3. This prevents materials or dust from falling into the bearing and affecting its normal operation, thereby extending the service life of the equipment.

[0052] A sprocket 24 is provided at one end of the auger conveyor shaft 21 near the feed inlet 231. The sprocket 24 is located outside the feeding housing 22. A feeding motor 25 is also provided on the outside of the feeding housing 22. The feeding motor 25 and the auger conveyor shaft 21 are driven by a chain.

[0053] The discharge box 13 includes a horizontal connecting flange A and an inclined connecting flange B; the connecting flange A is connected to the discharge port 1211 of the housing 121, and the connecting flange B is connected to the inlet 231 of the feeding auger 2. By using the discharge box 13 to connect the inlet 231 of the feeding auger 2 and the discharge port 1211 of the dispersing conveyor 12, material dust is prevented from scattering and affecting the working environment.

[0054] The working process of this embodiment includes the following steps:

[0055] ① Start the drive motor 124 and the feeding motor 25, and use the loader to push all the material into the hopper 11;

[0056] ②The material falls down along the hopper 11 into the accumulation trough 123;

[0057] ③ The dispersing shaft 122 rotates, and two adjacent dispersing shafts 122 with opposite rotation directions cooperate to crush the lumpy material; the spiral scraper 1222 then pushes the dispersed material toward the discharge port 1211;

[0058] ④ The material enters the feed inlet 231 of the feeding auger 2 from the discharge port 1211 through the discharge box 13;

[0059] ⑤ The auger conveyor shaft 21 rotates, conveying the material from the inside of the feeding shell 22 to the discharge cylinder 223;

[0060] ⑥ The material flows out from the discharge cylinder 223 and enters the subsequent processing steps.

[0061] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that: there are several feeding augers 2, and several discharge ports 1211 are arranged in parallel. The discharge ports 1211 divide the material accumulation groove 123 of the housing 121 into N segments; N spiral scrapers 1222 are arranged on the dispersing shaft 122, and the rotation direction of each spiral scraper 1222 corresponds to the position of the discharge port 1211.

[0062] Each spiral scraper 1222 corresponds to a section of the material trough 123, which can break up the material and push it to the corresponding discharge port 1211, thereby enabling several feeding augers 2 to feed material at the same time.
