Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rice hullers, in particular to a high-efficiency multi-channel rice huller. Background Art
[0002] A rice huller is a grain processing machine that removes the husk of rice to make brown rice. It can remove the outer shell of rice, reduce the risk of rice grains bursting and damage to the surface, and keep the brown rice as intact as possible.
[0003] A Chinese patent discloses a high-efficiency multi-channel rice huller (authorization announcement number CN214051750U). This patented technology sets a first drive motor to drive the reciprocating screw through the driving gear and the driven gear to make the discharge barrel reciprocate left and right, so that the rice is evenly spread on each processing roller, achieving better processing effect and avoiding secondary processing.
[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: In existing rice hullers, since the depth of the feed pipe is fixed, when the rice variety needs to be changed, if the depth of the feed pipe is not adjustable, it may cause the flow state of the rice during the feeding process to change, thereby affecting the shelling effect. What is more serious is that since the depth of the feed pipe is not adjustable, once a rice variety that is not suitable for the current feed pipe depth is encountered, the operator often has to interrupt production, disassemble and replace the entire feed device. This process is not only cumbersome and time-consuming, but also increases the difficulty of operation and labor intensity, and greatly reduces the continuous operation capacity and production efficiency of the equipment. Utility Model Content
[0005] The technical problem to be solved by the present invention is that in the prior art, since the depth of the feed pipe is fixed, when the rice variety needs to be changed, if the depth of the feed pipe is not adjustable, it is often necessary to stop the machine and replace the entire feed device, which not only increases the difficulty of operation, but also reduces the continuous operation capacity of the equipment. For this reason, we propose an efficient multi-channel rice huller.
[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a high-efficiency multi-channel rice husker, comprising a rice husker body, two feed pipes are installed on the top of the rice husker body, a movable groove is provided on the top of the feed pipe, an extension pipe is slidably connected inside the movable groove, through grooves are provided on both sides of the feed pipe, hollow blocks are fixedly connected on both sides of the extension pipe, clamping grooves are provided at both ends of the inner cavity of the through groove, adjustment grooves and through slots are provided at both ends of the hollow block, a pressing block is slidably connected inside the adjusting groove, one end of the pressing block is fixedly connected to a connecting plate, and one end of the connecting plate is fixedly connected to a clamping plate.
[0007] Preferably, a limiting hole is provided at one end of the connecting plate, a limiting rod is fixedly connected to the interior of the hollow block, and a surface of the limiting rod is slidably connected to the interior of the limiting hole.
[0008] Preferably, one end of the connecting plate is fixedly connected to a return spring, and one end of the return spring is fixedly connected to the interior of the hollow block.
[0009] Preferably, the clamping plate is slidably connected to the inside of the clamping slot, and the outer shape of the clamping plate is consistent with the inner shape of the clamping slot.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.
[0020] Reference Figure 1 - Figure 4 As shown, the utility model provides a technical solution: an efficient multi-channel rice husker, comprising a rice husker body 1, two feed pipes 2 are installed on the top of the rice husker body 1, a movable groove 3 is provided on the top of the feed pipe 2, an extension pipe 4 is slidably connected inside the movable groove 3, a through groove 5 is provided on both sides of the feed pipe 2, a hollow block 6 is fixedly connected on both sides of the extension pipe 4, a clamping groove 7 is provided at both ends of the inner cavity of the through groove 5, an adjustment groove 8 and a through slot 12 are provided at both ends of the hollow block 6, and the interior of the adjustment groove 8 is slidably connected to the feed pipe 2. There is a pressing block 9, one end of the pressing block 9 is fixedly connected to a connecting plate 10, and one end of the connecting plate 10 is fixedly connected to a clamping plate 11. The staff adjusts the extension tube 4 up and down so that the extension tube 4 can slide inside the movable groove 3, and then moves the pressing block 9 to drive the connecting plate 10, so that the clamping plate 11 is inserted into the clamping groove 7 to fix the position of the extension tube 4, so that the extension tube 4 can be adjusted to a suitable height as needed to adapt to the processing needs of different types of rice or different batches, thereby improving production efficiency.
[0021] Reference Figure 3 and Figure 4 As shown, in this embodiment: a limiting hole 13 is opened at one end of the connecting plate 10, and a limiting rod 14 is fixedly connected to the inside of the hollow block 6, and the surface of the limiting rod 14 is slidably connected to the inside of the limiting hole 13. The limiting hole 13 and the limiting rod 14 are used in conjunction with each other. When the connecting plate 10 moves inside the hollow block 6, it is ensured that the connecting plate 10 will not deviate from the predetermined trajectory during the sliding process, thereby effectively preventing structural failure or performance degradation caused by position offset.
[0022] Reference Figure 3 and Figure 4 As shown, in this embodiment: one end of the connecting plate 10 is fixedly connected to a return spring 15, and one end of the return spring 15 is fixedly connected to the inside of the hollow block 6. When an external force acts on the connecting plate 10, causing it to move relative to the hollow block 6, the return spring 15 will be compressed or stretched. Once the external force disappears, the return spring 15 will use its elastic potential energy to automatically push or pull the connecting plate 10 back to its initial position, making it faster for staff to use.
[0023] Reference Figure 2 and Figure 3As shown, in this embodiment: the snap-in plate 11 is slidably connected to the inside of the snap-in groove 7, and the external shape of the snap-in plate 11 is consistent with the internal shape of the snap-in groove 7. Since the external shape of the snap-in plate 11 is completely consistent with the internal shape of the snap-in groove 7, this design ensures the precise positioning of the two during connection. Once the snap-in plate 11 slides into the snap-in groove 7, a stable connection can be achieved, which is not prone to loosening or dislocation, thereby improving the stability and reliability of the entire structure.
[0024] Reference Figure 2 As shown, in this embodiment: guide grooves 16 are provided at both ends of the inner cavity of the movable groove 3, and guide blocks 17 are fixedly connected to both ends of the extension tube 4. The coordinated use of the guide grooves 16 and the guide blocks 17 can ensure that the extension tube 4 maintains linear motion when moving in the movable groove 3, avoiding deviation or shaking, thereby improving the stability of the overall structure.
[0025] Reference Figure 2 As shown, in this embodiment: the materials of the feed pipe 2 and the extension pipe 4 are both high-strength wear-resistant alloy steel. High-strength wear-resistant alloy steel not only has excellent wear resistance, can withstand the friction and impact generated by rice during the flow process for a long time, reduce equipment failures and downtime due to wear, but also has good corrosion resistance and toughness, ensuring stable operation in a humid and dusty working environment, thereby extending the service life of the equipment.
[0026] Working principle: The staff adjusts the extension tube 4 up and down so that the extension tube 4 can slide inside the movable groove 3, and then moves the pressing block 9 to drive the connecting plate 10, so that the clamping plate 11 is inserted into the inside of the clamping groove 7 to fix the position of the extension tube 4, so that the extension tube 4 can be adjusted to a suitable height as needed to adapt to the processing needs of different types of rice or different batches, thereby improving production efficiency. The limiting hole 13 and the limiting rod 14 are used in conjunction with each other. When the connecting plate 10 moves inside the hollow block 6, it is ensured that the connecting plate 10 will not deviate from the predetermined trajectory during the sliding process, thereby effectively preventing structural failure or performance degradation caused by position offset. When an external force acts on the connecting plate 10, causing it to move relative to the hollow block 6, the return spring 15 will be compressed or stretched. Once the external force disappears, the return spring 15 will use its elastic potential energy to automatically push or pull the connecting plate 10 back to its original position. Its initial position makes it faster for staff to use it. Since the external shape of the clamping plate 11 is completely consistent with the internal shape of the clamping groove 7, this design ensures the precise positioning of the two when connected. Once the clamping plate 11 slides into the clamping groove 7, a stable connection can be achieved, which is not easy to loosen or dislocate, thereby improving the stability and reliability of the entire structure. The coordinated use of the guide groove 16 and the guide block 17 can ensure that the extension tube 4 maintains linear motion when moving in the movable groove 3, avoiding offset or shaking, thereby improving the stability of the overall structure. High-strength wear-resistant alloy steel, this material not only has excellent wear resistance, can withstand the friction and impact generated by rice during the flow process for a long time, reduce equipment failures and downtime caused by wear, but also has good corrosion resistance and toughness, ensuring stable operation in humid and dusty working environments, and extending the service life of the equipment.
