Abstract
Description
Technical Field
[0001] This application relates to the field of rice hulling technology, and in particular to a rice hulling machine that is easy to feed. Background Technology
[0002] A rice huller is a grain processing machine that removes the husk from paddy rice to produce brown rice. Current rice hullers typically have their feed inlet located at the top of the machine, making feeding inconvenient and requiring manual handling, thus increasing the difficulty of rice processing.
[0003] To address the aforementioned issues, patent document CN219580618U discloses a convenient rice huller, the structure of which includes a base, a feeding mechanism, a feeding hopper, a transmission motor, a fixed bracket, a rice huller, and a feeding hopper. The feeding hopper is equipped with a movable shaft, and the feeding mechanism is movably mounted on the feeding hopper via the movable shaft. The rice huller is fixedly mounted on the base, and the feeding mechanism has a feeding hopper at its bottom.
[0004] While the aforementioned solutions can meet the basic requirements for automatic rice lifting and feeding, at least the following shortcomings have been found in actual use: During the process of lifting and conveying rice from the feeding hopper to the feed hopper at the top of the rice huller using the feeding mechanism, when the amount of rice remaining in the feeding hopper is relatively small, a small amount of rice may not be lifted and conveyed, remaining in the feeding hopper, thus resulting in incomplete lifting and conveying of the rice; moreover, the amount of rice entering the rice huller cannot be controlled during the lifting and conveying process, and if the amount of rice entering the rice huller is too large, it will affect the hulling quality of the rice.
[0005] Therefore, we propose a rice huller that is easy to feed to solve the above problems. Utility Model Content
[0006] The purpose of this application is to provide a rice huller that facilitates feeding, capable of lifting and conveying all the paddy rice into the rice huller body without leaving any paddy rice residue in the paddy rice container, achieving efficient and thorough feeding, and controlling the amount of paddy rice fed in, thus avoiding the effect of excessive or insufficient paddy rice entering the rice huller body and affecting the hulling quality.
[0007] The above-mentioned technical objective of this application is achieved through the following technical solution: a rice huller that facilitates feeding, comprising a base and a rice huller body and a lifting and feeding mechanism disposed on the top of the base. The rice huller body is fixedly installed on the top of the base, and a feeding hopper is fixedly installed on the top of the rice huller body. The lifting and feeding mechanism includes two vertical plates, a rice holding tank, two guide columns, and a lifting drive assembly. Both vertical plates are fixedly installed on the top of the base and located on the left side of the rice huller body. Guide grooves are provided on the sides of the two vertical plates that are close to each other. The rice holding tank is located between the two vertical plates, and the top of the rice holding tank has an open structure. The two guide columns are respectively fixedly installed on the front and rear outer walls of the rice holding tank. The ends of the two guide columns that are far apart from each other are slidably installed in the corresponding guide grooves. The lifting drive assembly is disposed on the top of the two vertical plates, and a discharge pipe is fixedly installed at the center of the bottom of the rice holding tank.
[0008] By adopting the above technical solution, the lifting drive component is used to lift the rice container to the top of the feed hopper, so that the rice in the rice container can be discharged from the discharge pipe and enter the feed hopper.
[0009] A further feature of this application is that the guide groove includes a vertical groove portion and an inclined groove portion, and the vertical groove portion and the inclined groove portion are connected.
[0010] By adopting the above technical solution, the guide column and guide groove work together to guide the rice container to rise and fall vertically in the vertical groove and to rise and fall at an angle in the inclined groove. In the later stage of lifting, the position of the rice container can be automatically adjusted so that its feed pipe is accurately aligned with the feed hopper of the rice huller body, ensuring a stable feeding process and preventing rice from spilling.
[0011] A further configuration of this application is as follows: the lifting drive assembly includes two fixed beams, an I-shaped winding wheel, a traction rope, and a motor. The two fixed beams are both fixedly installed on the top right side of the two upright plates. The I-shaped winding wheel is rotatably installed between the two fixed beams. The traction rope is wound on the I-shaped winding wheel. One end of the traction rope is fixedly connected to the right outer wall of the rice container. The motor is fixedly installed on one side of one of the fixed beams. The output shaft end of the motor is fixedly connected to the I-shaped winding wheel.
[0012] By adopting the above technical solution, the traction rope can be raised and lowered by driving the I-shaped winding wheel with a motor. This allows the rice container to slide with the two guide columns in the corresponding guide grooves, greatly reducing the labor intensity of manual feeding and quickly raising the rice to the height of the feeding hopper, thus significantly improving the feeding effect.
[0013] A further feature of this application is that two rotating shafts are rotatably installed between the two upright plates, and I-shaped guide wheels are fixedly mounted on both rotating shafts. The end of the traction rope away from the I-shaped winding wheel passes between the two I-shaped guide wheels.
[0014] By adopting the above technical solution and designing an I-shaped guide wheel, the movement direction of the traction rope can be guided, thereby enabling the traction rope to smoothly pull and lift the rice container.
[0015] A further feature of this application is that the bottom inner wall of the rice container is a sloping surface structure with a central concave depression.
[0016] By adopting the above technical solution, the rice grains can be gathered towards the center under the action of gravity, ensuring that all the rice grains in the rice container flow out from the feed pipe.
[0017] A further provision of this application is that the bottom of the rice container is provided with a feeding control component, which includes an electric telescopic rod, a connecting ear, and a plug. The electric telescopic rod is fixedly installed at the bottom of the rice container, the connecting ear is fixedly installed at the output shaft end of the electric telescopic rod, and the plug is fixedly installed on one side of the connecting ear, with the top of the plug extending into the feeding pipe.
[0018] By adopting the above technical solution, the electric telescopic rod is used to control the vertical movement of the plug, which enables the opening and closing of the plug and controls the amount of material fed. When feeding is required, the electric telescopic rod extends to make the plug leave the feeding pipe, and the rice flows out smoothly; when feeding is not required, the electric telescopic rod retracts, and the plug seals the feeding pipe to prevent rice leakage.
[0019] A further feature of this application is that the inner wall of the feed tube and the outer surface of the plug are both smooth surfaces, and the top of the plug is in sliding sealing contact with the inner wall of the feed tube.
[0020] By adopting the above technical solution, it is ensured that the top of the plug can smoothly enter and exit the feed pipe.
[0021] A further feature of this application is that the top of the plug has a centrally convex arc-shaped surface structure, a vertical rod is fixedly installed at the center of the top of the plug, the top of the vertical rod passes through the feed pipe, and multiple evenly distributed barbs are fixedly installed on the vertical rod.
[0022] By adopting the above technical solution, the top of the plug is designed with a centrally convex arc-shaped structure, which prevents the rice discharged from the feed pipe from piling up on the top of the plug. The design of the upright and the barbed hook can clear the rice in the feed pipe during the reciprocating lifting and lowering of the plug, preventing rice particles from clogging the feed pipe and ensuring smooth feeding.
[0023] A further feature of this application is that a baffle cloth cover is fixedly installed at the bottom of the rice container. The baffle cloth cover is a cylindrical shape with openings at both the top and bottom, and the feeding pipe, electric telescopic rod, connecting lug, and plug are all located inside the baffle cloth cover.
[0024] By adopting the above technical solution, the baffle cloth can effectively prevent rice from scattering during the feeding process, ensuring that all the rice discharged from the feeding pipe falls into the feeding hopper, so that the rice can be dehulled by the rice huller body.
[0025] A further feature of this application is that the top of the base is provided with a clearance hole located between the two vertical plates, and the diameter of the clearance hole is larger than the outer diameter of the baffle cloth cover.
[0026] By adopting the above technical solution and the design of the clearance hole, when the rice container descends to the machine base, it can avoid the baffle cloth cover, the feeding pipe and the electric telescopic rod, thereby allowing the rice container to be stably placed on the machine base.
[0027] This application includes at least one of the following beneficial technical effects:
[0028] 1. The design of this application improves the feeding mechanism, which can lift and transport all the rice into the rice huller body, without leaving any rice residue in the rice container, thus achieving a highly efficient and thorough lifting and feeding effect.
[0029] 2. The feeding control component designed in this application can control the intermittent discharge of rice from the rice container from the feeding pipe and into the feeding hopper, thereby controlling the amount of rice fed and preventing the amount of rice entering the rice huller from being too large or too small, which would affect the hulling quality.
[0030] 3. The design of this application is such that the plug drives the upright and the barbed hook to move up and down with the plug, which can clear the rice in the feeding pipe, prevent the rice particles from clogging the feeding pipe, and ensure smooth feeding. The design of the baffle cloth cover can effectively prevent the rice from scattering during the feeding process, and ensure that all the rice discharged from the feeding pipe falls into the feeding hopper for subsequent rice dehulling processing.

[0038] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0039] See Figures 1-6 This application provides a rice huller for easy feeding, including a base 1, a rice huller body 2 and a lifting and feeding mechanism disposed on top of the base 1. The rice huller body 2 is fixedly installed on top of the base 1, and a feeding hopper 3 is fixedly installed on top of the rice huller body 2. The lifting and feeding mechanism includes two vertical plates 4, a rice holding hopper 6, two guide columns 7 and a lifting drive assembly. Both vertical plates 4 are fixedly installed on top of the base 1 and located on the left side of the rice huller body 2. Guide grooves 5 are provided on the side of the two vertical plates 4 that are close to each other. The rice holding hopper 6 is located on the left side of the rice huller body 2. Between the two upright plates 4, the top of the rice holding tank 6 is open. Two guide columns 7 are fixedly installed on the front and rear outer walls of the rice holding tank 6 respectively. The ends of the two guide columns 7 that are far apart from each other are slidably installed in the corresponding guide grooves 5. The lifting drive assembly is set on the top of the two upright plates 4. The lifting drive assembly is used to lift the rice holding tank 6 above the feed hopper 3 to facilitate the addition of rice into the rice huller body 2. The bottom inner wall of the rice holding tank 6 is a sloping surface structure with a central concave shape. A feed pipe 14 is fixedly installed at the center of the bottom of the rice holding tank 6.
[0040] In this embodiment, the guide groove 5 includes a vertical groove and an inclined groove, which are connected. The vertical groove is used to guide the rice container 6 to rise and fall vertically, and the inclined groove is used to guide the rice container 6 to rise and fall tilted.
[0041] In this embodiment, the lifting drive assembly includes two fixed beams 8, an I-shaped winding wheel 9, a traction rope 10, and a motor 11. The two fixed beams 8 are fixedly installed on the top right side of the two upright plates 4. The I-shaped winding wheel 9 is rotatably installed between the two fixed beams 8. The traction rope 10 is wound on the I-shaped winding wheel 9. One end of the traction rope 10 is fixedly connected to the right outer wall of the rice container 6. The motor 11 is fixedly installed on one side of one of the fixed beams 8. The output shaft end of the motor 11 is fixedly connected to the I-shaped winding wheel 9. It should be noted that the traction rope 10 can be made of soft steel wire rope or nylon braided rope, which has the advantages of being strong, wear-resistant, and not easily broken. The motor 11 is a reversible motor.
[0042] In this embodiment, two rotating shafts 12 are rotatably installed between the two upright plates 4. I-shaped guide wheels 13 are fixedly mounted on both rotating shafts 12. The end of the traction rope 10 away from the I-shaped winding wheel 9 passes between the two I-shaped guide wheels 13, which can stably guide the movement direction of the traction rope 10, so that the traction rope 10 can smoothly pull and lift the rice container 6.
[0043] In this embodiment, a feeding control component is provided at the bottom of the rice holding tank 6. The feeding control component includes an electric telescopic rod 15, a connecting ear 16, and a plug 17. The electric telescopic rod 15 is fixedly installed at the bottom of the rice holding tank 6, the connecting ear 16 is fixedly installed at the output shaft end of the electric telescopic rod 15, and the plug 17 is fixedly installed on one side of the connecting ear 16. The top of the plug 17 extends into the feeding pipe 14. The inner wall of the feeding pipe 14 and the outer surface of the plug 17 are both smooth surfaces. The top of the plug 17 slides and seals against the inner wall of the feeding pipe 14. By utilizing the telescopic feature of the electric telescopic rod 15, the plug 17 can be controlled to move vertically back and forth, thereby intermittently sealing the bottom opening of the feeding pipe 14. This controls the rice in the rice holding tank 6 to intermittently enter the feed hopper 3, controlling the amount of rice fed and preventing the amount of rice entering the rice huller body 2 from being too large or too small, which would affect the hulling quality.
[0044] In this embodiment, the top of the plug 17 is a centrally convex arc-shaped structure. A vertical rod 18 is fixedly installed at the center of the top of the plug 17. The top of the vertical rod 18 passes through the feed pipe 14. Multiple evenly distributed barbs 19 are fixedly installed on the vertical rod 18. During the reciprocating lifting and lowering process of the vertical rod 18 and the barbs 19 driven by the plug 17, the rice in the feed pipe 14 can be cleared, preventing the rice grains from clogging the feed pipe 14 and ensuring smooth feeding.
[0045] In this embodiment, a baffle cover 20 is fixedly installed at the bottom of the rice container 6. The baffle cover 20 is a cylindrical shape with openings at both the top and bottom. The feed pipe 14, electric telescopic rod 15, connecting lug 16 and plug 17 are all located inside the baffle cover 20. The top of the base 1 is provided with a clearance hole 21 located between the two upright plates 4. The diameter of the clearance hole 21 is larger than the outer diameter of the baffle cover 20.
[0046] In this embodiment, it should be noted that both the motor 11 and the electric telescopic rod 15 are commercially available, and their wiring connection and control methods are mature technologies in the field, which will not be elaborated here.
[0047] With the above structure, the rice huller provided in this application, which facilitates feeding, allows the following operation: When rice needs to be fed into the rice huller body 2, the motor 11 is started and rotates in reverse. The output shaft of the motor 11 drives the I-shaped winding wheel 9 to rotate in reverse, and the traction rope 10 is gradually released. Since one end of the traction rope 10 is fixed to the outer right side of the rice holding tank 6, under the weight of the rice holding tank 6 and with the sliding cooperation of the guide column 7 in the inclined groove of the guide groove, the rice holding tank 6 can drive the two guide columns 7 to first move downwards along the inclined groove of the guide groove 5, and then descend vertically through the vertical groove of the guide groove 5 until the bottom of the rice holding tank 6 contacts the upper surface of the machine base 1. At this time, the motor 11 stops running, and the baffle cloth cover 20 and the discharge pipe 14... With the electric telescopic rod 15 positioned within the clearance hole 21, the rice container 6 can be stably placed on the machine base 1. Then, an appropriate amount of rice is poured into the rice container 6, and the motor 11 is controlled to rotate in the forward direction. The output shaft of the motor 11 drives the I-shaped winding wheel 9 to rotate in the forward direction, and the traction rope 10 is gradually wound up. Under the tension of the traction rope 10, the rice container 6 begins to rise. During the rising process, the guide posts 7 on the front and rear sides of the rice container 6 first slide upward along the vertical groove of the guide groove 5 to ensure that the rice container 6 rises vertically and smoothly. When the guide posts 7 enter the inclined groove of the guide groove 5, the rice container 6 will tilt and rise until the discharge pipe 14 at the bottom of the rice container 6 is aligned with the feed hopper 3 at the top of the rice huller body 2, at which point the motor 11 stops running.
[0048] Next, the electric telescopic rod 15 is controlled to reciprocate in extension and retraction. The output shaft of the electric telescopic rod 15 pushes the connecting ear 16 and the plug 17 to move vertically reciprocally. By controlling the vertical reciprocating movement of the plug 17, the bottom end of the discharge pipe 14 can be intermittently blocked. This allows the rice in the rice container 6 to be intermittently discharged from the discharge pipe 14 and fall into the feed hopper 3. Then, by controlling the operation of the rice huller body, the rice can be dehulled. This allows the amount of rice fed into the rice huller body 2 to be controlled, avoiding excessive or insufficient rice entering the rice huller body 2, which would affect the dehulling quality.
[0049] During the vertical reciprocating movement of the plug 17, the upright rod 18 and the barbed hook 19 will reciprocate and rise and fall with the plug 17, which can clear the rice in the feed pipe 14, prevent the rice grains from clogging the feed pipe 14, and ensure smooth feeding. The baffle cloth cover 20 can effectively prevent the rice from scattering during the feeding process, ensuring that all the rice discharged from the feed pipe 14 falls into the feed hopper 3 for subsequent rice hulling processing.
[0050] After all the rice in the container 6 has been discharged, the electric telescopic rod 15 is reset so that the plug 17 blocks the bottom opening of the feed pipe 14. Following the above operating steps, the rice can continue to be lifted and the rice can be controlled to enter the rice huller body 2 intermittently.
