Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, and in particular to a grain hulling machine. Background Technology

[0002] Cereal processing refers to the process of using cereals as raw materials and processing them through a series of mechanical, physical, and chemical methods to change their original form and properties and make them into various products that meet people's different needs. After harvesting, many cereals such as rice, wheat, and corn are usually covered with a husk or chaff. The function of a dehulling machine is to remove these husks so that the grains can be better processed later.

[0003] Some traditional grain processing hulling machines do not have a mechanism to adjust the feed flow rate when feeding grains. The feed speed depends entirely on the natural falling speed of the grains or the fixed conveying speed of the feeding device. This makes it impossible to flexibly adjust according to the working status of the hulling machine and the characteristics of the grains, which easily leads to the problem of mismatch between the feed speed and the processing capacity of the hulling machine. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the feeding speed of grains in the hulling machine cannot be controlled in the existing technology. Therefore, we propose a hulling machine for grain processing.

[0005] To achieve the above objectives, this application adopts the following technical solution: a grain dehulling machine, comprising a dehulling machine body, a discharge pipe installed at the bottom end of the dehulling machine body, a feed pipe installed at the top end of the dehulling machine body, an adjustment groove provided on one side of the feed pipe, a fixed plate fixedly connected to the top end of the dehulling machine body, a fixed block fixedly connected to the top end of the fixed plate, an adjustment rod slidably connected inside the fixed block, a handle fixedly connected to one side of the adjustment rod, a flow limiting plate fixedly connected to the other side of the adjustment rod, sliding grooves provided at both the front and rear ends of the fixed block, a sliding rod slidably connected inside the sliding grooves, a push-pull plate fixedly connected to the end of the sliding rod away from the fixed block, a first elastic spring sleeved on the surface of the sliding rod, the front and rear ends of the first elastic spring being fixedly connected to the fixed block and the push-pull plate respectively, and several limiting grooves provided at both the front and rear ends of the adjustment rod, with the sliding rod inserted into the limiting grooves.

[0006] Preferably, the top and bottom of the fixed block are provided with first sliding grooves, and the top and bottom of the adjusting rod are fixedly connected with first sliders, and the inside of the first sliding groove is slidably connected to the first sliders.

[0007] Preferably, a second sliding groove is provided on both sides of the sliding groove, and a second slider is fixedly connected to both sides of the sliding rod, with the interior of the second sliding groove slidably connected to the second slider.

[0008] Preferably, two energy storage springs are fixedly connected to the side of the handle near the fixing block, and the side of the energy storage springs away from the handle is fixedly connected to the fixing block.

[0009] Preferably, the end of the sliding rod has a bevel.

[0010] Preferably, the top of the flow restrictor is provided with an inclined chamfer.

[0011] Preferably, a connecting block is fixedly connected to one side of the inside of the feed pipe, a second elastic spring is fixedly connected to the bottom end of the connecting block, a pressing plate is fixedly connected to the bottom end of the second elastic spring, and the bottom end of the pressing plate is designed to fit against the top end of the flow limiting plate.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, when the operator needs to adjust the speed at which grains enter the hulling machine, the two push-pull plates are pulled outwards, causing the sliding rod to be pulled out from inside the limiting groove, thus releasing the fixing of the adjusting rod. At this time, the adjusting rod is moved, causing the flow-limiting plate to move to a suitable position for grain feeding. Then, the sliding rod is aligned with the limiting groove, and the elastic force of the first spring is released, causing the sliding rod to be inserted into the limiting groove, thereby fixing the position of the flow-limiting plate. By adjusting the opening of the flow-limiting plate, the speed at which grains enter the hulling machine can be precisely controlled. This helps to maintain a suitable filling amount and flow rate of grains in the hulling machine, avoiding machine overload, jamming, or even damage due to excessive feeding, and also preventing production efficiency from being affected by excessively slow feeding.

[0015] 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, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0016] Reference Figures 1-4 As shown, this utility model provides a technical solution: a grain hulling machine, including a hulling machine body 1, a discharge pipe 2 installed at the bottom end of the hulling machine body 1, a feed pipe 3 installed at the top end of the hulling machine body 1, an adjustment groove 4 opened on one side of the feed pipe 3, a fixing plate 5 fixedly connected to the top end of the hulling machine body 1, a fixing block 6 fixedly connected to the top end of the fixing plate 5, an adjustment rod 7 slidably connected inside the fixing block 6, a handle 8 fixedly connected to one side of the adjustment rod 7, a flow limiting plate 9 fixedly connected to the other side of the adjustment rod 7, sliding grooves 10 opened at both the front and rear ends inside the fixing block 6, a sliding rod 11 slidably connected inside the sliding grooves 10, a push-pull plate 12 fixedly connected to the end of the sliding rod 11 away from the fixing block 6, a first elastic spring 13 sleeved on the surface of the sliding rod 11, the front and rear ends of the first elastic spring 13 being fixedly connected to the fixing block 6 and the push-pull plate 12 respectively. Next, several limiting grooves 14 are provided at both the front and rear ends of the adjusting rod 7. The sliding rod 11 is inserted into the limiting groove 14. When the operator needs to adjust the speed at which the grains enter the hulling machine body 1, the two push-pull plates 12 are pulled outward to pull the sliding rod 11 out of the limiting groove 14, thus releasing the fixing of the adjusting rod 7. At this time, the adjusting rod 7 is moved to move the flow limiting plate 9 to a suitable position for grain feeding. Then, the sliding rod 11 is aligned with the limiting groove 14. At this time, the elastic force of the first elastic spring 13 is released, which causes the sliding rod 11 to be inserted into the limiting groove 14, thereby fixing the position of the flow limiting plate 9. By adjusting the opening of the flow limiting plate 9, the speed at which the grains enter the hulling machine body 1 can be precisely controlled. This helps to maintain a suitable filling amount and flow rate of grains in the hulling machine body 1, avoiding machine overload, jamming, or even damage due to excessive feeding, and also preventing excessively slow feeding from affecting production efficiency.

[0017] Reference Figure 4As shown in this embodiment: the top and bottom of the fixed block 6 are provided with first sliding grooves 15, and the top and bottom of the adjusting rod 7 are fixedly connected with first sliders 16. The interior of the first sliding groove 15 is slidably connected to the first slider 16. Through the setting of the first sliding groove 15 and the first slider 16, the position of the adjusting rod 7 can have a stable limiting effect, so that the adjusting rod 7 will not deviate when it drives the flow limiting plate 9 to move, thereby effectively ensuring the accuracy and stability of the position adjustment of the flow limiting plate 9.

[0018] Reference Figure 5 As shown in this embodiment: a second sliding groove 17 is provided on both sides inside the sliding groove 10, and a second slider 18 is fixedly connected to both sides of the sliding rod 11. The interior of the second sliding groove 17 is slidably connected to the second slider 18. Through the setting of the second sliding groove 17 and the second slider 18, the sliding rod 11 can form a stable limiting effect when sliding inside the sliding groove 10, so that the sliding rod 11 will not move excessively, and thus the process of releasing the fixing plate 5 is more stable.

[0019] Reference Figure 5 As shown in this embodiment: two energy storage springs 19 are fixedly connected to the side of the handle 8 near the fixing block 6, and the side of the energy storage springs 19 away from the handle 8 is fixedly connected to the fixing block 6. By setting the energy storage springs 19, when the grain feeding is completed, the adjusting rod 7 is released from the fixing. At this time, the elastic force stored in the energy storage springs 19 is released, which drives the adjusting rod 7 to return to the initial position, thereby achieving the quick reset of the flow limiting plate 9 after use, which is convenient for the next use.

[0020] Reference Figure 5 As shown in this embodiment: the end of the sliding rod 11 is provided with an inclined surface 20. By setting the inclined surface 20, when it is necessary to adjust the position of the flow limiting plate 9, the sliding rod 11 can be slid out from the inside of the limiting groove 14 by pushing the adjusting rod 7, thereby achieving the quick release and fixation of the flow limiting plate 9 and further improving the operating efficiency.

[0021] Reference Figure 3 As shown in this embodiment, the top of the flow-limiting plate 9 is provided with an inclined chamfer 21. By setting the inclined chamfer 21, when the grains come into contact with the surface of the flow-limiting plate 9, they can slide directly into the interior of the shelling machine body 1 through the flow-limiting plate 9 without accumulating on the flow-limiting plate 9, thereby further reducing the occurrence of blockage and improving the shelling effect.

[0022] Reference Figure 2As shown in this embodiment: a connecting block 22 is fixedly connected to one side of the inside of the feed pipe 3, a second elastic spring 23 is fixedly connected to the bottom end of the connecting block 22, and a pressing plate 24 is fixedly connected to the bottom end of the second elastic spring 23. The bottom end of the pressing plate 24 is designed to fit against the top end of the flow limiting plate 9. When the grains are conveyed into the inside of the hulling machine body 1 through the feed pipe 3, the pressing plate 24 will always fit against the surface of the flow limiting plate 9 due to the elastic force of the second elastic spring 23, thereby preventing the grains from leaking out from the gap between the regulating trough 4 and the flow limiting plate 9, effectively improving the sealing of the grains during the feeding and conveying process.

[0023] Working principle: When the operator needs to adjust the speed at which grains enter the hulling machine body 1, the two push-pull plates 12 are pulled outwards, causing the sliding rod 11 to be pulled out from inside the limiting groove 14, thus releasing the fixing of the adjusting rod 7. At this time, the adjusting rod 7 is moved, causing the flow-limiting plate 9 to move to a suitable position for grain feeding. Then, the sliding rod 11 is aligned with the limiting groove 14. The spring force of the first elastic spring 13 is released, causing the sliding rod 11 to insert into the limiting groove 14, thus fixing the position of the flow-limiting plate 9. By adjusting the opening of the flow-limiting plate 9, the speed at which grains enter the hulling machine body 1 can be precisely controlled, which helps... To maintain a suitable filling amount and flow rate of grains within the hulling machine body 1, preventing machine overload, jamming, or even damage due to excessively fast feeding, and also preventing production efficiency from being affected by excessively slow feeding, the first slide groove 15 and the first slider 16 provide a stable limiting effect during the adjustment of the position of the adjusting rod 7. This ensures that the adjusting rod 7 does not deviate when moving the flow limiting plate 9, effectively guaranteeing the accuracy and stability of the flow limiting plate 9's position adjustment. Furthermore, the second slide groove 17 and the second slider 18 provide a stable limiting effect when the sliding rod 11 slides within the slide groove 10. This prevents the sliding rod 11 from moving excessively, thus making the process of releasing the fixed plate 5 more stable. With the energy storage spring 19, after the grain feeding is complete, the adjusting rod 7 is released, releasing the stored elasticity and causing the adjusting rod 7 to return to its initial position. This achieves quick reset of the flow-limiting plate 9 after use, facilitating future use. With the inclined surface 20, when the position of the flow-limiting plate 9 needs adjustment, pushing the adjusting rod 7 allows the sliding rod 11 to slide out of the limiting groove 14, achieving quick release of the flow-limiting plate 9. To further improve operational efficiency, the inclined chamfer 21 allows grains to slide directly into the hulling machine body 1 through the flow-limiting plate 9 when they come into contact with its surface, preventing them from accumulating on the flow-limiting plate 9. This further reduces blockages and improves the hulling effect. When the grains are conveyed into the hulling machine body 1 through the feed pipe 3, the pressing plate 24 remains in contact with the surface of the flow-limiting plate 9 due to the elastic force of the second spring 23, preventing the grains from leaking out of the gap between the adjusting groove 4 and the flow-limiting plate 9, thus effectively improving the sealing during the grain feeding and conveying process.
