Description

Technical Field

[0001] This utility model relates to the field of rice primary processing and hulling technology, specifically a rice primary processing and hulling device. Background Technology

[0002] Paddy processing is the process of converting paddy into products that can be eaten directly or used for other purposes. Generally, the process begins with cleaning the paddy to remove impurities, then hulling it into brown rice, followed by milling to remove the bran layer and obtain polished white rice. Polishing may also be performed to make the rice grains smoother. Finally, the rice is graded, screened, and packaged.

[0003] The existing Chinese patent announcement number CN222197045U, entitled "A Dehulling Device for Rice Processing," clearly states in its abstract that "this utility model involves placing rice into a hopper, adjusting the feeding valve according to the required amount of rice to control the feeding speed and quantity of rice, preventing a large accumulation of rice from reducing dehulling efficiency, and using a feeding pipe and guide chute to transport the rice to the dehulling mechanism. The guide chute is located directly above the dehulling mechanism to prevent rice from splashing everywhere during feeding. The rice is dehulled under the pressure of the dehulling mechanism, and a blower blows air onto the falling brown rice and rice husks. The dehulled brown rice falls onto the conveyor plate and is discharged from the outlet, while the rice husks are blown out through the discharge port of the husk collection hood, thus separating the rice husks from the brown rice. This eliminates the need for a separate dehulling device, reducing the labor intensity of the workers."

[0004] However, due to the differences in physical characteristics of different varieties of rice, such as grain hardness and size, existing dehulling devices, with their fixed spacing between the rubber rollers on both sides, cannot achieve ideal dehulling results for all varieties of rice. Parameter adjustments or equipment selection are often required depending on the rice variety, which presents certain shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a rice primary processing and dehulling device to solve the problem mentioned in the background art that existing dehulling devices are difficult to achieve ideal dehulling effects for all varieties of rice.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rice primary processing and hulling device includes a mounting box and two rubber rollers. The mounting box has four sliding grooves on its front and rear sides, and sliding parts are slidably disposed inside the sliding grooves. The rubber rollers are rotatably mounted inside the sliding parts on the front and rear sides. An adjustment component is disposed at the front of the mounting box, and a drive component is disposed at the rear of the mounting box.

[0008] The adjustment assembly includes a bidirectional threaded rod, a threaded tube is provided on the outer side of the front sliding member, an installation gear is provided on the inner side of the bidirectional threaded rod, an installation groove is provided at the bottom of the installation gear, a spring is provided at the bottom of the inner side of the installation groove, and a retaining tooth is provided at the top of the spring;

[0009] The drive assembly includes a connector and a hydraulic push rod. Two synchronous gears are rotatably arranged inside the connector. A first synchronous pulley is provided on the synchronous gear, and a second synchronous pulley is provided on the outer side of the two rubber rollers.

[0010] In a preferred embodiment of this utility model, the bidirectional threaded rod is rotatably installed, and the two sides of the bidirectional threaded rod are threadedly connected to two threaded tubes.

[0011] In a preferred embodiment of this utility model, the retaining tooth is slidably connected to the mounting groove, and the top of the retaining tooth meshes with the mounting gear.

[0012] In a preferred embodiment of this utility model, a threaded groove is provided on the inner side of the tooth, and a threaded bolt is provided inside the threaded groove, and the threaded bolt is threadedly connected to the threaded groove.

[0013] In a preferred embodiment of this utility model, the threaded bolt is provided with a plug, and two sockets are provided on one side of the mounting groove, and the plug is installed and removed from the sockets.

[0014] In a preferred embodiment of this utility model, the bottom of the hydraulic push rod is fixedly installed, and the top telescopic end of the hydraulic push rod is connected to a connector.

[0015] In a preferred embodiment of this utility model, a motor is provided on the outside of the connector, and a gear is installed on the drive shaft of the motor.

[0016] In a preferred embodiment of this utility model, the mounting gears on both sides mesh with each other, and the two first synchronous pulleys mesh with the two second synchronous pulleys respectively through a synchronous belt.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0018] Beneficial effects: By rotating the mounting gear on the inside, i.e., rotating the bidirectional threaded rod, the sliding parts and rubber rollers on both sides move inward or outward simultaneously through threaded transmission, thus adjusting the distance between the two rubber rollers. This makes it more convenient to dehull different varieties of rice. After the distance between the two rubber rollers is adjusted, stop rotating the mounting gear. The spring pushes the locking teeth, causing them to lock into the bottom of the mounting gear, thus fixing the mounting gear and preventing it from rotating, thereby fixing the distance between the two rubber rollers. The locking teeth are fixed by inserting the insert block into the slot. The motor drives the mounting gear on one side to rotate, and through the gears, synchronous pulleys, and synchronous belts on both sides, the rubber rollers on both sides rotate inward simultaneously, thus dehulling the rice. Even when the rubber rollers on both sides move, the hydraulic push rod drives the connecting parts to extend and retract, thus ensuring that the synchronous belts on both sides are taut.

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] Please refer to Figures 1-5 This utility model discloses a rice primary processing and dehulling device, including a mounting box 1 and two rubber rollers 11. The mounting box 1 is a mounting structure used to install other structures. The two rubber rollers 11 are the main structure of the device and are used to dehull the rice. Four sliding grooves 12 are provided on the front and rear sides of the mounting box 1. Sliding elements 13 are slidably arranged inside the sliding grooves 12. The sliding elements 13 are locked inside the sliding grooves 12 and slide. The rubber rollers 11 are rotatably installed inside the sliding elements 13 on the front and rear sides. That is, the two rubber rollers 11 are installed inside the two pairs of sliding elements 13 and rotate.

[0029] An adjustment assembly is provided at the front of the mounting box 1. The adjustment assembly includes a bidirectional threaded rod 2 with opposite thread directions on both sides. A threaded tube 14 is provided on the outer side of the front sliding member 13. The bidirectional threaded rod 2 is rotatably mounted, and both sides of the bidirectional threaded rod 2 are threadedly connected to the two threaded tubes 14. An installation gear 21 is provided on the inner side of the bidirectional threaded rod 2. By rotating the installation gear 21 on the inner side, the bidirectional threaded rod 2 is rotated. Through threaded transmission, the sliding members 13 on both sides and the rubber rollers 11 move inward or outward simultaneously, thereby adjusting the distance between the two rubber rollers 11. This allows for the hulling of different varieties of rice, making it more convenient to use.

[0030] The bottom of the mounting gear 21 has a mounting groove 22, and the bottom inner side of the mounting groove 22 has a spring 23. The top of the spring 23 has a retaining tooth 3, which is slidably connected to the mounting groove 22. The top of the retaining tooth 3 meshes with the mounting gear 21. After the distance between the two rubber rollers 11 is adjusted, the rotation of the mounting gear 21 stops. The spring 23 pushes the retaining tooth 3, thereby locking the retaining tooth 3 at the bottom of the mounting gear 21, thus fixing the mounting gear 21 and preventing it from rotating, thus fixing the distance between the two rubber rollers 11. The inner side of the retaining tooth 3 has a mounting groove 22, and the bottom inner side of the mounting groove 22 has a spring 23. The spring 23 has a retaining tooth 3, which is slidably connected to the mounting groove 22. The top of the retaining tooth 3 meshes with the mounting gear 21. The device has a threaded groove 31, inside which is a threaded bolt 32. The threaded bolt 32 is threadedly connected to the threaded groove 31. The threaded bolt 32 is provided with a plug 33. There are two insertion ports 24 on one side of the mounting groove 22. The plug 33 is installed and removed from the insertion ports 24. When the retaining tooth 3 is engaged in the mounting gear 21, or when the retaining tooth 3 is disassembled in the mounting gear 21, the plug 33 engages with the two insertion ports 24 respectively. That is, by rotating the threaded bolt 32 on the outside, the plug 33 is inserted into the insertion port 24, thereby fixing the retaining tooth 3.

[0031] A drive assembly is provided at the rear of the mounting box 1. The drive assembly includes a connector 4 and a hydraulic push rod 34. Two synchronous gears 42 are rotatably arranged inside the connector 4, and the mounting gears 21 on both sides mesh with each other. A motor 41 is provided on the outside of the connector 4. The drive shaft of the motor 41 is connected to the mounting gear 21 on one side. That is, the motor 41 drives the mounting gear 21 on one side to rotate, thereby causing the mounting gears 21 on both sides to rotate in opposite directions. A first synchronous wheel 43 is provided on the synchronous gear 42, and a second synchronous wheel 44 is provided on one side of the outside of the two rubber rollers 11.

[0032] The bottom of the hydraulic push rod 34 is fixedly installed, and the top telescopic end of the hydraulic push rod 34 is connected to the connecting piece 4. The two first synchronous pulleys 43 are respectively engaged with the two second synchronous pulleys 44 through the synchronous belt. That is, the first synchronous pulley 43 on the left is engaged with the second synchronous pulley 44 on the left, and the first synchronous pulley 43 on the right is engaged with the second synchronous pulley 44 on the right. Thus, through the synchronous pulleys and synchronous belts on both sides, the rubber rollers 11 on both sides rotate inward at the same time, that is, the rice is hulled. Even when the rubber rollers 11 on both sides move, the connecting piece 4 is extended and retracted through the hydraulic push rod 34, thereby ensuring that the synchronous belts on both sides are taut.

[0033] The working principle of this utility model is as follows: By rotating the mounting gear 21 on the inner side, i.e., rotating the bidirectional threaded rod 2, the sliding parts 13 on both sides and the rubber rollers 11 move inward or outward simultaneously through threaded transmission, thereby adjusting the distance between the two rubber rollers 11. This allows for the hulling of different varieties of rice, making it more convenient to use. Once the distance between the two rubber rollers 11 is adjusted, the rotation of the mounting gear 21 is stopped. The spring 23 pushes the locking teeth 3, causing the locking teeth 3 to engage with the bottom of the mounting gear 21, thus fixing the mounting gear 21 and preventing it from rotating. The spacing between the two rubber rollers 11 is fixed. When the locking tooth 3 is engaged in the mounting gear 21, the insert block 33 mates with the two insertion ports 24. That is, by rotating the threaded bolt 32 on the outside, the insert block 33 is inserted into the insertion port 24, thereby fixing the locking tooth 3. The motor 41 drives the mounting gear 21 on one side to rotate. Through the synchronous pulleys and synchronous belts on both sides, the rubber rollers 11 on both sides rotate inward at the same time, thus removing the husk from the rice. Even when the rubber rollers 11 on both sides move, the hydraulic push rod 34 drives the connecting piece 4 to extend and retract, thereby ensuring that the synchronous belts on both sides are taut.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
