Description

Technical Field

[0001] This application relates to the field of cereal production feeding technology, and in particular to an automatic feeding device for raw material pretreatment in cereal production. Background Technology

[0002] In automated production lines for cereal products such as oatmeal, the pre-processing and feeding of raw materials is the primary and crucial step. Currently, the industry commonly uses automated feeding equipment such as chain conveyors, bucket conveyors, or belt conveyors to lift and deliver materials. These devices typically consist of a casing, drive components, a circulating conveying unit, and a series of evenly distributed hoppers. During operation, the hoppers receive raw materials at the feeding station and are then conveyed to a designated height or position for unloading.

[0003] However, existing technical solutions still have several problems that need to be addressed in practical applications. First, since oatmeal raw materials are often in flake, powder, or have a certain degree of stickiness, they are prone to sticking or bridging in the hopper, resulting in incomplete unloading. This not only wastes raw materials and contaminates batches, but also requires frequent shutdowns for manual cleaning, which seriously affects production efficiency and continuity. During the conveying process, especially in the unloading section, friction and pressure between the material and the inner wall of the equipment can easily cause material to stick, resulting in material residue on the inclined surface below the hopper, which leads to incomplete unloading. This not only affects production efficiency, but also affects the feeding of subsequent hoppers. Therefore, an automatic feeding device for raw material pretreatment in oatmeal production is proposed to solve the problems mentioned above. Summary of the Invention

[0009] Optionally: The number of hoppers is several and they are installed at equal intervals outside the conveying unit. Automatic feeding is achieved through the cyclic displacement of the conveying unit. The feeding bin is fixed to one side of the machine housing.

[0012] Optionally: the side plate away from the horizontal plate is adapted to the inner wall of the shell, the horizontal plate has an extension groove that slides with the guide block, and a return spring connected to the end of the guide block is installed on the inner wall of the extension groove.

[0013] Optionally: the interior of the horizontal plate is provided with a tube groove communicating with the extension groove, the interior of the limiting seat is hollow and fixed to the bottom side of the material shell, wherein the end of the lifting rod away from the first gravity block passes through the interior of the limiting seat and is rotatably connected to the bottom side of the horizontal plate, and the guide is fixedly set inside the limiting seat.

[0014] Optionally: The guide includes a fastening sleeve fixed inside the limiting seat, a guide rod is threaded inside the fastening sleeve, and a ball bearing that rolls with the guide groove is rotatably installed at the other end of the guide rod, so that the rotation of the lifting rod is achieved through the rolling engagement between the guide and the guide groove.

[0015] Optionally: The swing assembly includes a swing rod hinged to the material feeding side of the shell, wherein a return spring is fixed between the swing rod and the shell, and a ball is fixed to one end of the swing rod.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. In the present invention, during the feeding process, the periodic changes in the spatial position and posture of the hopper during the cyclical movement of the conveying unit change the relative position of gravity. Combined with the knocking vibration triggered by its own gravity, the raw materials that may adhere to the side wall of the shell are effectively loosened, preventing them from caking or forming material arches during the conveying process.

[0020] 2. In this invention, as the conveying unit continues to move, the pushing component moves downward due to gravity, thereby scraping away the material in the hopper. This clears the material from the hopper, ensuring clean discharge and providing clean space for the next feeding.

[0021] 3. In this invention, during the material feeding process, the gravity component comes above the hopper. As the first gravity block drives the pushing component to move downward, the second gravity block slides down along the lifting rod under the action of gravity and inertia, and cooperates with the abutment rod of the first gravity block to push the swing rod again, which further speeds up the material discharge speed, ensures clean unloading, and avoids affecting the subsequent production process due to incomplete material discharge.

[0022] 4. In this invention, the pushing component can flexibly adjust its length and shape according to the distribution of materials in the hopper and the pushing requirements, so as to better adapt to the pushing work under different conditions, improve the accuracy and effectiveness of pushing, and ensure that the materials can be pushed out smoothly.

[0035] The following is in conjunction with the appendix Figure 1 - Figure 10 This application will be described in further detail.

[0036] Example 1, such as Figure 1 - Figure 4As shown, this is the first embodiment of the present invention. This embodiment provides an automatic feeding device for raw material pretreatment in oatmeal production. The device comprises an automatic feeding equipment 1 consisting of a housing 11, a feeding bin 12, a drive assembly 13, a conveying unit 14, and a hopper 15. The hopper 15 includes a hollow shell 151 and a side panel 152 fixed to the side wall of the shell 151. The side panels 152 are used for feeding material in two symmetrically distributed units. It should be noted that there are several hoppers 15 installed at equal intervals outside the conveying unit 14. Automatic feeding is achieved through the cyclic displacement of the conveying unit 14. The feeding bin 12 is fixed to one side of the housing 11. The drive assembly 13 is disposed outside the housing 11 to drive the conveying unit 14.

[0037] Specifically, a material discharge channel is provided on the top side of the casing 11 relative to the feeding bin 12. When the conveying unit 14 moves cyclically, the periodic changes in the spatial position and posture of the hopper 15 realize automatic feeding and material feeding. In addition, the casing of the feeding bin 12 is replaced by a screw conveyor for material conveying and cooperates with the hopper 15 for automatic feeding.

[0038] Example 2, as Figure 2 - Figure 10 As shown, this is the second embodiment of the present invention. Unlike the first embodiment, in order to provide feeding and unloading of the hopper 15, a processing unit 2 is provided at the bottom of the shell 151 in this embodiment. The processing unit 2 includes a gravity component 3 disposed at the bottom of the shell 151 and a pushing component 4 and a swinging component 6 disposed on the shell 151. The gravity component 3 is connected to the pushing component 4 and the swinging component 6 respectively, and drives the pushing component 4 and the swinging component 6 respectively as the conveying unit 14 moves, so as to realize the automatic processing of the feeding and unloading process and greatly improve the production efficiency.

[0039] like Figure 5 - Figure 7 and Figure 10 As shown, the gravity component 3 includes a lifting rod 31 that slides through the inside of the hopper 15, a first gravity block 32 and a second gravity block 33 installed on the lifting rod 31. One end of the lifting rod 31 is fixedly engaged with the pushing component 4. Specifically, the lifting rod 31, as a key component of the gravity component 3, slides through the inside of the hopper 15 and is fixedly engaged with the pushing component 4 at one end, serving as a bridge connecting the gravity block and the pushing component 4. It can accurately transmit the gravity of the gravity block to the pushing component 4 to realize the pushing action.

[0040] To drive the swing assembly 6, both gravity block 1 32 and gravity block 2 33 have abutment rods 34 on their outer surfaces, and elastic heads 35 are bolted to the same end of both abutment rods 34. The elastic heads 35 can be made of rubber. The bottom side of the shell 151 is also provided with a limiting seat 5 and a guide 51 for driving the lifting rod 31 to rotate. The lifting rod 31 has a guide groove 37 inside that rolls with the guide 51. The guide groove 37 is spiral in shape. In addition, the surface of the guide groove 37 can be hardened or fitted with a lubricating bushing to further reduce wear. Specifically, gravity block 32 is located at the end of lifting rod 31, gravity block 33 is splinedly connected to lifting rod 31, and a return spring 36 is rotatably installed between gravity block 33 and limit seat 5, which is wound around the outside of lifting rod 31. It should be noted that during the rotation of gravity block 33, due to the connection through return spring 45, a certain shaking effect will be generated, which will cause the side plate 42 to vibrate or shake slightly along the pushing direction. This can be used not only for discharging material from hopper 15 but also for cleaning the pushing assembly 4.

[0041] It should be noted that the weight of gravity block 1 32 is greater than that of gravity block 2 33, and the side of the elastic head 35 is inclined, so that the presence of the two gravity blocks can provide sufficient gravity drive at different stages. In this embodiment, when the conveying unit 14 drives the empty hopper 15 to run below the loading bin 12 and receive material, the hopper 15 is in the first posture, such as horizontal. At this time, gravity block 1 32 is in a low position, and the swing component 6 is not triggered. When the hopper 15 is fully loaded and runs to the lifting section, the gravity of the material causes the pushing component 4 and the lifting rod 31 to move slightly downward, driving gravity block 1 32 to move downward. Its elastic head 35 contacts and presses down the swing component 6, so that it plays a knocking role. When the hopper 15 runs to the unloading position and tilts, gravity block 2 33 slides down along the lifting rod 31 under the action of gravity, pushing the pushing component 4 to perform a scraping action. At the same time, the lifting rod 31 rotates under the action of the guide 51 and the guide groove 37, thereby realizing the rapid unloading operation.

[0042] like Figure 5 - Figure 8 As shown, the pushing assembly 4 includes a telescopically connected horizontal plate 41 and side plate 42, which allows the pushing assembly 4 to flexibly adjust its length and shape according to the distribution of materials in the hopper 15 and the pushing requirements, so as to better adapt to the pushing work under different conditions, improve the accuracy and effectiveness of pushing, and ensure that the materials can be pushed out smoothly. Specifically, a guide block 44 and an elastic cloth 43 are fixed on one side of the side plate 42, which can form a flexible sealing function between the horizontal plate 41 and the side plate 42 to prevent materials from getting stuck in the telescopic movement of the horizontal plate 41 and the side plate 42. It should be noted that the elastic cloth 43 is made of a wear-resistant, tear-resistant and flexible material.

[0043] The guide block 44 is telescopically connected to the horizontal plate 41, and the elastic cloth 43 is fixed between the horizontal plate 41 and the side plate 42. In use, the guide block 44 slides in the extension groove 46, providing precise linear motion guidance for the side plate 42 and preventing the pusher plate from deviating or jamming. Specifically, the side of the side plate 42 away from the horizontal plate 41 is adapted to the inner wall of the material shell 151. The horizontal plate 41 has an extension groove 46 that slides with the guide block 44 inside. The inner wall of the extension groove 46 is equipped with a reset spring 45 connected to the end of the guide block 44. Since the material discharge of the hopper 15 is inclined, the reset spring 45 not only provides the reset force for the pusher plate to retract, but also enables the side plate 42 to fit tightly against the material discharge surface of the hopper 15, improving the material pushing effect.

[0044] In this embodiment, the interior of the horizontal plate 41 is provided with a tube groove 47 that communicates with the extension groove 46. The interior of the limiting seat 5 is hollow and fixed to the bottom side of the shell 151. The end of the lifting rod 31 away from the gravity block 32 passes through the interior of the limiting seat 5 and is rotatably connected to the bottom side of the horizontal plate 41. The guide 51 is fixedly installed inside the limiting seat 5.

[0045] To achieve the rotation of the lifting rod 31, such as Figure 9 and Figure 10 As shown, the guide 51 includes a fastening sleeve 511 fixed inside the limiting seat 5. A guide rod 512 is threadedly connected inside the fastening sleeve 511, and a ball bearing 513 that rolls with the guide groove 37 is rotatably mounted on the other end of the guide rod 512. The rotation of the lifting rod 31 is achieved through the rolling engagement between the guide 51 and the guide groove 37. It should be noted that the threaded connection between the guide rod 512 and the fastening sleeve 511 not only allows for wear compensation but also enables the optimal fit to be restored after long-term use, thus extending the service life.

[0046] To facilitate the use of the pusher assembly 4, such as Figure 5 - Figure 7As shown, the swing assembly 6 includes a swing rod 61 hinged to the material discharge side of the material shell 151. A return spring 62 is fixed between the swing rod 61 and the material shell 151, and a ball 63 is fixed to one end of the swing rod 61. Specifically, there can be multiple swing assemblies 6 distributed at equal intervals. It should be noted that the swing rod 61 swings and strikes the material discharge side of the material shell 151, which is the last channel and outlet for material to flow out of the hopper 15. This is the most prone to blockage, which can directly interrupt or hinder the entire discharge process, resulting in residue in the hopper 15. During the unloading process, the inner wall of this surface continuously rubs and contacts the flowing material. Since it is the side wall of the unloading path, the material is prone to adhere and clump here due to pressure, humidity, or static electricity. When the gravity block 32 shifts, the elastic head 35 at the front end of the upper abutment rod 34 contacts and presses down one end of the swing rod 61, causing the other end to swing towards the inner wall of the material shell 151. Since the hopper 15 will have a feeding stage and a discharging stage according to the conveying unit 14, the gravity component 3 will match the movement of the hopper 15 according to the change of gravity, so that the knocking function occurs in the early stage when the material is just filled and the horizontal conveying begins, as well as in the discharging stage. When the material is just loaded, the bridging may have just occurred and the strength is not high. Timely vibration can easily shake it off, preventing it from solidifying into a stubborn blockage that is difficult to deal with in the subsequent conveying process. Therefore, it is much more efficient to deal with it when the discharging is not smooth.

[0047] Example 3, as Figure 8 and Figure 9 As shown, this is the third embodiment of the present invention. Unlike the second embodiment, to improve the telescopic effect of the feeding assembly 4, in this embodiment, a protective assembly 7 located inside the limiting seat 5 is provided on the bottom side of the material shell 151. The protective assembly 7 includes a pressure cylinder 71 fixedly disposed and a piston 72 slidably disposed inside the pressure cylinder 71. The end of the piston 72 extends to the outside of the pressure cylinder 71, and an infusion tube 77 penetrating the inside of the tube groove 47 and fixed to the guide block 44 is fixed to one side of the pressure cylinder 71. The infusion tube... 77 can be a corrugated hose, and a protective pad needs to be installed inside the tube groove 47 to prevent damage to the infusion tube 77. Specifically, the protection component 7 also includes a guide seat 75 rotatably mounted on the bottom side of the material shell 151 and splinedly connected to the lifting rod 31. A ball bearing 74 is rotatably mounted on one end of the piston 72 extending outside the pressure cylinder 71. The outer side of the guide seat 75 is provided with inclined guide surfaces 76 of varying heights. The ball bearing 74 rolls in contact with the inclined guide surfaces 76. A buffer spring 73 is installed outside the piston 72. It should be noted that a storage tank connected to the pressure cylinder 71 needs to be installed inside the limit seat 5. Two check valves are provided on the pressure cylinder 71, and an outlet hole is opened in the guide block 44. Therefore, when the lifting rod 31 moves, the piston 72 reciprocates within the pressure cylinder 71 through the action of the guide seat 75 and the ball bearing 74, thus lubricating and protecting the extension and retraction of the pushing component 4.

[0048] Combined with appendix Figure 1 - Figure 10 The working principle of the above embodiments is as follows:

[0049] The present invention utilizes the periodic changes in the spatial position and posture of the hopper 15 when the conveying unit 14 moves cyclically to change the relative position of gravity block 1 32 and gravity block 2 33, thereby automatically and orderly cooperating with the material shell 151 to perform loading and unloading operations.

[0050] First, during the feeding stage, the conveying unit 14 moves the empty hopper 15 to below the feeding bin 12. The material falls into the hopper 15 and begins to move upward when it is fully loaded. Since there is a certain gap between the pushing component 4 and the bottom side of the shell 151, when the hopper 15 is fully loaded and begins to move upward, the pushing component 4 will be moved downward by the material and the rising gravity. At this time, the gravity block 32 moves downward as well. During the downward movement of the gravity block 32, the elastic head 35 on it will press down the swing rod 61, causing it to swing inward and strike the side of the hopper 15 where the material is being fed.

[0051] As the conveying unit 14 conveys, the hopper 15 moves to the other side of the conveying unit 14. At this time, the feeding side of the hopper 15 faces the feeding part of the casing 11, thus automatically feeding the cereal raw materials. As the conveying unit 14 continues to move, the gravity component 3 moves above the hopper 15. The gravity block 32 moves downward according to gravity, which drives the pushing component 4 to move downward through the lifting rod 31. The pushing component 4 moves downward to scrape the material in the hopper 15. At the same time, during the extension and retraction of the lifting rod 31, it will connect with the guide 51. The rolling engagement of the guide groove 37 causes rotation; at this time, the second gravity block 33 slides down along the lifting rod 31 under the action of gravity and inertia, and cooperates with the abutment rod 34 of the first gravity block 32 to push the swing rod 61 again, speeding up the discharge speed and ensuring clean unloading. During the rotation, the second gravity block 33 will produce a certain shaking effect due to the connection through the second return spring 45, which will cause a small amplitude tremor or shaking of the side plate 42 along the pushing direction. It can be used not only for the discharge of the hopper 15, but also for the cleaning of the pushing assembly 4.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
