Description

Technical Field

[0001] This utility model relates to the field of rice hullers, and more specifically, to a hopper feeding mechanism for a rice huller. Background Technology

[0002] A rice huller is a grain processing machine that removes the husk from paddy rice to produce brown rice. It removes the outer husk, reducing grain breakage and surface damage, and preserving the brown rice as much as possible. It mainly consists of a hopper feeding device, a machine head, a husk separation chamber, a gearbox, and a frame.

[0003] Rice hullers typically have a high hopper. When hulling rice, a conveying device is needed to transport the rice to the top of the hopper. However, in existing rice hullers, a large amount of rice remains inside the conveying device during transport, which can cause blockages. Furthermore, the rice may be crushed and damaged during transport, affecting the quality of the finished rice. Therefore, we have proposed a new hopper feeding mechanism for rice hullers to solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a hopper feeding mechanism for a rice huller. It solves the problem that a large amount of rice remains inside the conveying equipment during the conveying process, which can cause serious congestion. Furthermore, the rice may be squeezed and damaged during the conveying process, affecting the quality of the rice produced later.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A hopper feeding mechanism for a rice huller includes a hopper and a conveyor belt. The hopper is located on one side of the conveyor belt. A transmission control feeding mechanism is fixedly connected inside the conveyor belt, and a support frame is movably connected to the outside of the transmission control feeding mechanism. Several material conveying mechanisms are fixedly connected to the outside of the conveyor belt, and a transmission belt is provided on one side of the bottom of the conveyor belt.

[0009] Furthermore, the transmission control feeding mechanism includes a drive motor, drive wheels, tracks, drive rods, control bars, and control motors. There are two drive wheels arranged symmetrically, located at both ends inside the tracks, and both drive wheels are connected to the tracks for transmission. The output end of the drive motor is fixedly connected to the shaft of one of the drive wheels via a coupling. The control bar is fixedly connected to one end of the drive rod, and the other end of the drive rod is fixedly connected to the output end of the control motor via a coupling.

[0010] Furthermore, the outer side of the track is fixedly connected to the inside of the conveyor belt, the drive rod is laterally located on the opposite side of the two drive wheels, and one end of the drive rod extends to the outer side of the conveyor belt, and the control bar is located on the outer side of the conveyor belt.

[0011] Furthermore, the support frame has two supports, and both ends are movably connected to the shaft of the drive wheel via rotating shafts. The drive rod passes through the two support frames laterally, and the connection between the drive rod and the support frame is movably connected via bearings. The control motor is fixedly connected to the outside of the support frame away from the control bar.

[0012] Furthermore, the material conveying mechanism includes a fixed base, a connecting shaft, an adjusting bar, and a material conveying hopper. The connecting shaft is movably connected to the middle position of one side of the fixed base via a torque spring, and the adjusting bar is fixedly connected to the outside of the connecting shaft. The material conveying hopper is fixedly connected to the end of the connecting shaft away from the fixed base.

[0013] Furthermore, a guide plate is fixedly connected to the inside of the hopper on the side away from the control bar, and a discharge chute is opened on the top side of the hopper, with the bottom end of the discharge chute in contact with the top end of the guide plate.

[0014] Furthermore, the side of the fixed seat away from the connecting shaft is fixedly connected to the outer side of the conveyor belt, and a stabilizing frame is fixedly connected to the end of the fixed seat near the control bar, and the bottom of the hopper is in close contact with the inner side of the stabilizing frame.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] In this scheme, a drive motor drives a track via a drive wheel to drive another drive wheel. At this time, the conveyor belt retracts and follows the track. Simultaneously, the conveyor belt drives the fixed seat to move upward until the other hopper stops at the same height as the conveyor belt. The above operation is repeated. When the hopper containing rice moves to directly above the feed hopper, the control motor is started to rotate the control bar. When the control bar contacts one end of the regulating bar, the control bar continues to rotate upward, thereby lifting one end of the regulating bar upward. This helps to ensure that the equipment can perform uninterrupted feeding operations, improves work efficiency, and avoids a large amount of rice remaining inside the conveyor mechanism when reloading. Furthermore, it ensures stability during feeding and feeding processes and avoids spillage.

[0018] This solution controls the feeding hopper to be cleaned to one side of the feed hopper by rotating the connecting shaft clockwise through the other end of the control bar. The bottom of the other end of the feeding hopper separates from the stabilizing frame, and the rice is conveyed along the guide plate towards the feed hopper until the control bar and the control bar come into contact and separate. At this time, the torque spring reacts on the connecting shaft, causing it to drive the feeding hopper to reset. This facilitates the automation of the feeding, conveying and discharging process. Secondly, the integrated design of the equipment not only improves the overall performance of the equipment, but also reduces the failure rate and maintenance costs. Attached Figure Description

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Example 1:

[0027] Please see Figures 1-4A hopper feeding mechanism for a rice huller includes a hopper 1 and a conveyor belt 2. The hopper 1 is located on one side of the conveyor belt 2. A transmission control feeding mechanism 3 is fixedly connected inside the conveyor belt 2, and a support frame 6 is movably connected to the outside of the transmission control feeding mechanism 3. Several material conveying mechanisms 4 are fixedly connected to the outside of the conveyor belt 2, and a transmission belt 5 is provided on one side of the bottom of the conveyor belt 2.

[0028] Example 2:

[0029] In view of the above embodiment 1, further description is provided, see reference. Figure 1 , Figure 2 , Figure 3 and Figure 4 The transmission control feeding mechanism 3 includes a drive motor 301, drive wheels 302, a track 303, a drive rod 304, a control bar 305, and a control motor 306. Two drive wheels 302 are provided and arranged symmetrically, located at both ends inside the track 303, and both drive wheels 302 are connected to the track 303 for transmission. The output end of the drive motor 301 is fixedly connected to the shaft of one of the drive wheels 302 via a coupling. The control bar 305 is fixedly connected to one end of the drive rod 304, and the other end of the drive rod 304 is fixedly connected to the control motor via a coupling. At the output end of 306, the outer side of the track 303 is fixedly connected to the inside of the conveyor belt 2. The drive rod 304 is laterally located on the opposite side of the two drive wheels 302, and one end of the drive rod 304 extends to the outer side of the conveyor belt 2. The control bar 305 is located on the outer side of the conveyor belt 2. There are two support frames 6, and both ends are movably connected to the axis of the drive wheel 302 through the rotating shaft. The drive rod 304 laterally passes through the two support frames 6, and the connection between the drive rod 304 and the support frame 6 is movably connected through the bearing. The control motor 306 is fixedly connected to the outer side of the support frame 6 away from the control bar 305.

[0030] The drive motor 301 drives the track 303 through the drive wheel 302 to drive the other drive wheel 302. At this time, the conveyor belt 2 follows the track 303 and moves along its trajectory. At the same time, the conveyor belt 2 drives the fixed seat 401 to move upward until the other hopper 404 stops at the same height as the conveyor belt 5. The above operation is repeated. When the hopper 404 containing rice moves to the side directly above the feed hopper 1, the control motor 306 is started to rotate through the control bar 305. When the control bar 305 contacts one end of the regulating bar 403, the control bar 305 continues to rotate upward, thereby lifting one end of the regulating bar 403 upward. This helps to ensure that the equipment can carry out uninterrupted feeding operations and improve work efficiency. At the same time, it avoids a large amount of rice remaining inside the conveyor mechanism when reloading. Secondly, it ensures the stability during feeding and feeding and avoids spillage.

[0031] Example 3:

[0032] In view of the above embodiments 1 and 2, further description is provided, please refer to... Figure 1 , Figure 2 and Figure 3 The material conveying mechanism 4 includes a fixed base 401, a connecting shaft 402, an adjusting bar 403, and a material conveying hopper 404. The connecting shaft 402 is movably connected to the middle of one side of the fixed base 401 via a torque spring, and the adjusting bar 305 is fixedly connected to the outside of the connecting shaft 402. The material conveying hopper 404 is fixedly connected to the end of the connecting shaft 402 away from the fixed base 401. A guide plate 7 is fixedly connected to the inside of the material conveying hopper 404 away from the side of the controlling bar 305. A discharge trough 8 is opened on one side of the top of the material conveying hopper 404, and the bottom end of the discharge trough 8 is in contact with the top end of the guide plate 7. The side of the fixed base 401 away from the connecting shaft 402 is fixedly connected to the outside of the conveyor belt 2. A stabilizing frame 9 is fixedly connected to the end of the fixed base 401 near the controlling bar 305, and the bottom of the material conveying hopper 404 is in close contact with the inside of the stabilizing frame 9.

[0033] The other end of the control bar 403 drives the connecting shaft 402 to rotate clockwise, controlling the conveying hopper 404 to be cleaned to one side of the feed hopper 1. The bottom of the other end of the conveying hopper 404 separates from the stabilizer 9, and the rice is conveyed along the guide plate 7 towards the feed hopper 1 until the control bar 305 contacts and separates from the control bar 403. At this time, the torque spring reaction force is applied to the connecting shaft 402, causing it to drive the conveying hopper 404 to reset. This facilitates the realization of automated conveying, feeding and discharging workflows. Secondly, the integrated design of the equipment not only improves the overall performance of the equipment, but also reduces the failure rate and maintenance costs.

[0034] Based on the above embodiments 1, 2, and 3, the working principle is further described below: In use, rice is conveyed by the conveyor belt 5 to the inside of the feeding hopper 404 at the same height. After filling, the conveyor belt 5 is stopped, and then the drive motor 301 is started, driving the track 303 through the drive wheel 302 to drive another drive wheel 302. At this time, the conveyor belt 2 retracts the track 303 and follows its trajectory. Simultaneously, the conveyor belt 2 drives the fixed seat 401 to move upwards until the other feeding hopper 404 stops at the same height as the conveyor belt 5. The above operation is repeated until the feeding hopper 404 containing rice moves to the inlet hopper 1... When the rice is directly above the side, the start control motor 306 rotates through the control bar 305. As a result, when the control bar 305 contacts one end of the regulating bar 403, the control bar 305 continues to rotate upward, thereby lifting one end of the regulating bar 403 upward. At this time, the other end of the regulating bar 403 drives the connecting shaft 402 to rotate clockwise, controlling the conveying hopper 404 to be washed to one side of the feeding hopper 1. The bottom of the other end of the conveying hopper 404 separates from the stabilizer 9, and the rice is conveyed along the guide plate 7 towards the feeding hopper 1 until the control bar 305 contacts and separates from the regulating bar 403. At this time, the torque spring reaction force is applied to the connecting shaft 402, causing it to drive the conveying hopper 404 to reset.

[0035] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
