Description

Technical Field

[0001] This invention belongs to the field of rice hulling machine technology, specifically, it relates to a rice hulling machine with anti-clogging function for rice processing and its usage method. Background Technology

[0002] Rice hullers are core equipment in rice processing production lines. They are mainly used to remove the outer husk of paddy rice and separate paddy rice from brown rice. They are widely used in large-scale grain processing industries. In the actual processing of paddy rice, the raw paddy rice usually contains various large impurities such as straw, broken branches, mud lumps, and clumps of rice grains. These impurities need to be screened out in advance during the feeding screening stage to prevent them from entering the core structure of the hull and affecting the hulling precision and the quality of the finished rice.

[0003] In continuous and large-scale rice processing production, a large amount of paddy raw materials are continuously and rapidly fed in. Various impurities mixed in are very easy to accumulate and adhere to the surface of the screen plate, clogging the screen holes and causing a significant decrease in screening efficiency. Once the screen holes are clogged, problems such as insufficient screening of raw materials, backflow of impurities, and paddy accumulation and blockage will occur. This will not only cause the processing production line to stop and be stuck, affecting the continuity of production, but also reduce the quality of the finished product of subsequent rice hulling processing because the impurities are not completely removed.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] A rice huller with anti-clogging function for rice processing includes a mounting frame and a second feed hopper mounted above the mounting frame. The second feed hopper has a screening plate inside its cavity and two sliding slots, each with a drive wheel. A rotating rod is mounted on one side wall opposite the two drive wheels, and a sleeve is mounted on the rotating rod. The sleeve has multiple circumferentially arranged and equidistant front and rear shovels, each symmetrically positioned. Each front and rear shovel is used to remove large impurities from the rice to prevent clogging of the screening plate. A front and rear collecting plate, also symmetrically positioned, is mounted above the second feed hopper and is used to collect large impurities removed by the front and rear shovels.

[0007] In a preferred embodiment of the present invention, a first feed hopper is provided on one side wall of the inner cavity of the mounting frame, a first discharge hopper is provided on the front side of the mounting frame, a second discharge hopper is also provided on one side wall of the mounting frame, a control panel is also provided on the front side of the mounting frame, and support seats are provided around the bottom of the mounting frame, with the four support seats being symmetrical to each other in pairs.

[0008] In a preferred embodiment of the present invention, the two opposite side walls of the inner cavity of the second feed hopper are also provided with tracks, the two tracks are symmetrical to each other, and four sliding rods are slidably arranged on each of the two tracks. Each sliding rod is symmetrical to each other in pairs, and the side walls of each sliding rod that are longitudinally opposite to each other are respectively arranged on the front collection plate and the rear collection plate.

[0009] In a preferred embodiment of the present invention, the rotating rod is provided with an irregular cross mounting plate between the drive wheel and the sleeve, and the two irregular cross mounting plates are respectively composed of multiple steeply inclined surfaces, gently inclined surfaces and moving surfaces.

[0010] In a preferred embodiment of the present invention, the outer surfaces of the two irregular cross mounting plates are provided with irregular slide rails, the two irregular slide rails are slidably provided with sliding balls, the two sliding balls are provided with rolling bearings, the two rolling bearings are symmetrical to each other, and the two rolling bearings are provided with positioning rods, the two positioning rods are symmetrical to each other.

[0011] In a preferred embodiment of the present invention, a rotating rod is provided on the opposite side wall of the two drive wheels, the two rotating rods are symmetrical to each other, the other end of the two rotating rods is rotatably mounted on the mounting plate, the two mounting plates are symmetrical to each other, and the two mounting plates are respectively slidably mounted on the opposite side wall of the inner cavity of the second discharge hopper.

[0012] In a preferred embodiment of the present invention, a movable slide groove is provided on one side wall opposite to the two mounting plates. The two movable slide grooves are symmetrical to each other. A sliding rod slides in the inner cavity of each of the two movable slide grooves. The two sliding rods are symmetrical to each other. A return spring is provided above each sliding rod. The other ends of the two return springs are respectively provided on the movable slide groove.

[0013] In a preferred embodiment of the present invention, a connecting rod is provided on one side wall opposite to the two sliding rods, the two connecting rods are symmetrical to each other, and a positioning rod is provided at the bottom of each of the two connecting rods.

[0014] In a preferred embodiment of the present invention, swing arms are movably provided on both sides of the two connecting rods, the four swing arms are symmetrical to each other, and the other ends of the four swing arms are respectively provided on the front collecting plate and the rear collecting plate.

[0015] The following are the steps for using a rice huller with an anti-clogging function for rice processing:

[0016] Step 1: Start the equipment through the control panel, check the operating status of the drive wheel, return spring, and each sliding transmission structure, and confirm that the front and rear collection plates open and close smoothly without jamming, ensuring that the transmission structure of the whole machine operates normally.

[0017] Step 2: Put the rice raw material to be processed into the second feed hopper. The raw material falls onto the surface of the screening plate. The screening plate performs preliminary screening and filtration of large impurities such as straw and gravel in the rice, thus completing the preliminary purification of the raw material.

[0018] Step 3: The drive wheel drives the rotating rod and sleeve to rotate, and the front and rear digging shovels continuously remove the impurities accumulated on the surface of the screening plate to avoid screen blockage and achieve uninterrupted anti-blocking operation.

[0019] Step 4: The irregular cross mounting plate, in conjunction with ball bearings and other transmission mechanisms, drives the connecting rod and swing arm to move in tandem, causing the two sets of collecting plates to reciprocate along the track, precisely receiving the impurities scooped up by the excavator and preventing them from scattering and flowing back.

[0020] Step 5: After screening and purification, the rice raw material enters the equipment for hulling. The finished rice is discharged from the first discharge hopper, and the collected impurities are discharged through the second discharge hopper, completing the entire rice screening and anti-clogging processing process.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] This invention uses a drive wheel to rotate a rotating rod and a sleeve. The front and rear shovels, symmetrically arranged at equal intervals around the circumference of the sleeve, continuously and dynamically remove accumulated impurities from the surface of the screening plate, thus improving the problem of material blockage in the feed screen of traditional rice hullers. Simultaneously, the symmetrically arranged front and rear collection plates accurately collect the impurities removed by the shovels, effectively collecting them and preventing them from scattering and flowing back, ensuring continuous and stable screening operations. This eliminates the need for frequent manual cleaning of the screen surface, significantly improving the screening efficiency and processing quality of rice, and meeting the needs of large-scale rice processing production.

[0023] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0040] Example 1:

[0041] like Figures 1 to 9 As shown, a rice huller with anti-clogging function for rice processing includes a mounting frame 1 and a second feed hopper 16 mounted on top of the mounting frame 1. The inner cavity of the second feed hopper 16 is provided with a screening plate 17. The second feed hopper 16 also has two sliding slots 26, each with a drive wheel 2. A rotating rod 21 is provided on one side wall opposite to the two drive wheels 2. A sleeve 22 is provided on the rotating rod 21, and multiple front digging shovels 2 are arranged circumferentially and at equal intervals on the sleeve 22. 21 and rear shovel 222, each front shovel 221 and rear shovel 222 are symmetrical to each other, each front shovel 221 and rear shovel 222 are used to dig out large impurities in rice to prevent the screening plate 17 from clogging; a front collection plate 3 and a rear collection plate 31 are provided above the second feed hopper 16, the front collection plate 3 and rear collection plate 31 are symmetrical to each other, the front collection plate 3 and rear collection plate 31 are used to collect large impurities in rice shoveled out by the front shovel 221 and rear shovel 222 respectively. Driven by the drive wheel 2, the rotating rod 21 and sleeve 22 rotate. The front and rear digging shovels 221 and 222, which are symmetrically arranged on the circumference of the sleeve 22, continuously and dynamically clean the impurities accumulated on the surface of the screening plate 17, which improves the problem of material blockage in the feed screen of traditional rice hullers to a certain extent. At the same time, the symmetrically arranged front and rear collection plates 3 and 31 can accurately receive the impurities scooped up by the digging shovels, effectively collect the impurities, prevent the impurities from scattering and flowing back, and ensure the continuous and stable operation of screening. There is no need for frequent manual cleaning of the screen surface, which greatly improves the screening efficiency and processing quality of rice processing and meets the needs of large-scale rice processing production.

[0042] like Figures 1 to 5 As shown in the specific embodiment, a first feed hopper 12 is provided on one side wall of the inner cavity of the mounting frame 1, a first discharge hopper 13 is provided on the front side of the mounting frame 1, a second discharge hopper 15 is also provided on one side wall of the mounting frame 1, a control panel 14 is also provided on the front side of the mounting frame 1, and support seats 11 are provided around the bottom of the mounting frame 1, with the four support seats 11 symmetrically arranged in pairs. In this configuration, the support seats 11 can provide stable support for the entire mounting frame 1, reducing vibration and displacement during equipment operation and improving the overall stability of the machine. The first feed hopper 12, the first discharge hopper 13, and the second discharge hopper 15 have clearly defined functions, respectively adapting to the auxiliary feeding of raw materials, the discharge of finished rice, and the diversion and discharge of impurities. Together with the control panel 14, intelligent control of parameters such as equipment start-up and shutdown and operating speed can be realized to meet the needs of automated processing.

[0043] like Figures 1 to 9 As shown, furthermore, the inner walls of the second feed hopper 16 are also provided with tracks 32 on opposite sides. The two tracks 32 are symmetrical to each other, and four sliding rods 321 are slidably arranged on each track 32. Each pair of sliding rods 321 is symmetrical to each other, and the longitudinally opposite side walls of each pair of sliding rods 321 are respectively set on the front collection plate 3 and the rear collection plate 31. In this arrangement, the symmetrically arranged tracks 32 provide precise sliding guidance for the sliding rods 321, restricting the movement trajectory of the sliding rods 321 and avoiding deviation and jamming. The sliding movement of the sliding rods 321 can drive the front collection plate 3 and the rear collection plate 31 to move smoothly back and forth along the tracks 32, ensuring the smoothness of the dynamic opening and closing operation of the collection plates and ensuring that the impurity collection operation is carried out accurately and orderly.

[0044] like Figures 1 to 9 As shown, furthermore, a non-circular cross mounting plate 4 is provided between the drive wheel 2 and the sleeve 22 on the rotating rod 21. The two non-circular cross mounting plates 4 are respectively composed of multiple steeply inclined surfaces 41, gently inclined surfaces 411, and moving surfaces 412. In this configuration, the non-circular cross mounting plate 4 rotates synchronously with the rotating rod 21. Through its own special curved surface structure of steeply inclined surfaces 41, gently inclined surfaces 411, and moving surfaces 412, it can form differentiated transmission trajectories, providing a stable power transmission foundation for the subsequent reciprocating transmission structure and realizing precise conversion of mechanical motion.

[0045] like Figures 1 to 9 As shown, furthermore, both irregularly shaped cross mounting plates 4 have irregularly shaped slide rails 413 on their outer surfaces. Sliding balls 42 are slidably mounted on both slide rails 413, and rolling bearings 421 are mounted on the two sliding balls 42. The two rolling bearings 421 are symmetrical to each other, and positioning rods 422 are mounted on both rolling bearings 421. The two positioning rods 422 are also symmetrical to each other. In this configuration, the irregularly shaped slide rails 413, in conjunction with the sliding balls 42, can significantly reduce frictional resistance during transmission and improve transmission smoothness. Through the rotational adaptability of the rolling bearings 421, the rotational motion of the irregularly shaped cross mounting plates 4 is converted into the vertical reciprocating linear motion of the positioning rods 422, achieving precise power conversion and stable output.

[0046] Example 2:

[0047] The difference between the above embodiments and this embodiment is that: Figures 1 to 9 As shown, a rice huller with anti-clogging function for rice processing has two drive wheels 2 with rotating rods 23 on opposite side walls. The two rotating rods 23 are symmetrical to each other. The other ends of the two rotating rods 23 are rotatably mounted on mounting plates 24. The two mounting plates 24 are symmetrical to each other and are slidably mounted on opposite side walls of the inner cavity of the second discharge hopper 15.

[0048] like Figures 1 to 9 As shown, in a specific embodiment, a movable slide groove 241 is provided on one side wall of the two mounting plates 24 facing each other. The two movable slide grooves 241 are symmetrical to each other, and a sliding rod 242 slides inside the cavity of each movable slide groove 241. The two sliding rods 242 are symmetrical to each other, and a return spring 243 is provided above each sliding rod 242. The other end of the two return springs 243 is respectively provided on the movable slide groove 241. In this configuration, the movable slide groove 241 provides a vertical sliding limit for the sliding rod 242, and the return spring 243 can provide an elastic return force during the up and down movement of the sliding rod 242, realizing the automatic rebound and reset of the sliding rod 242, ensuring the continuous cycle of reciprocating transmission operation. At the same time, the mounting plate 24 can slide slightly along the inner wall of the second discharge hopper 15 to adapt to the displacement deviation of the overall transmission structure.

[0049] like Figures 1 to 9 As shown, furthermore, a connecting rod 25 is provided on one side wall opposite to the two sliding rods 242. The two connecting rods 25 are symmetrical to each other, and a positioning rod 422 is provided at the bottom of each connecting rod 25. In this configuration, the positioning rod 422 transmits the vertical reciprocating power to the connecting rod 25, causing the connecting rod 25 to move vertically and reciprocally in sync with the sliding rod 242. The connecting rod 25, as an intermediate transmission connector, can stably transmit power, ensuring synchronous linkage of the transmission structures on both sides and avoiding problems such as asynchronous transmission and structural jamming.

[0050] like Figures 1 to 3 As shown, furthermore, swing arms 251 are movably mounted on both sides of the two connecting rods 25, with the four swing arms 251 symmetrically arranged in pairs. The other ends of the four swing arms 251 are respectively mounted on the front collecting plate 3 and the rear collecting plate 31. In this configuration, the swing arms 251 play a core role in reversing the motion, converting the vertical reciprocating motion of the connecting rods 25 into the horizontal reciprocating motion of the front collecting plate 3 and the rear collecting plate 31, realizing the dynamic opening and closing action of the collecting plates, adapting to the rotational impurity removal rhythm of the digging shovel, and accurately completing the impurity collection and avoidance operation.

[0051] Example 3:

[0052] This invention also discloses a method for using a rice huller with anti-clogging function for rice processing, the steps of which are as follows:

[0053] Step 1: Start the device through the control panel 14, check the operating status of the drive wheel 2, return spring 243, and each sliding transmission structure, and confirm that the front collection plate 3 and the rear collection plate 31 open and close smoothly without jamming, to ensure that the transmission structure of the whole machine operates normally.

[0054] Step 2: The rice raw material to be processed is put into the second feed hopper 16. The raw material falls onto the surface of the screening plate 17. The screening plate 17 performs preliminary screening and filtration of large impurities such as straw and gravel in the rice, thus completing the preliminary purification of the raw material.

[0055] Step 3: Drive wheel 2 drives rotating rod 21 and sleeve 22 to rotate, and uses front digging shovel 221 and rear digging shovel 222 to continuously remove impurities accumulated on the surface of screening plate 17, avoid screen hole blockage, and achieve uninterrupted anti-blocking operation.

[0056] Step 4: The irregular cross mounting plate 4, in conjunction with ball bearings and other transmission mechanisms, drives the connecting rod 25 and the swing arm 251 to move in tandem, causing the two sets of collecting plates to reciprocate along the track 32, precisely receiving the impurities scooped up by the excavator and preventing the impurities from scattering and flowing back.

[0057] Step 5: The screened and purified rice raw material enters the equipment for hulling. The finished rice is discharged from the first discharge hopper 13, and the collected impurities are discharged through the second discharge hopper 15, completing the entire rice screening and anti-clogging processing process.

[0058] The implementation principle of a rice huller with anti-clogging function for rice processing according to the present invention is as follows:

[0059] The equipment relies on the installation frame 1 as the main load-bearing structure, and the support seats 11 symmetrically arranged around the bottom can achieve stable support for the whole machine and ensure the stability of equipment operation. The operator can control the operation of the equipment through the control panel 14, and complete the basic processing flow of raw material feeding and finished product discharge in conjunction with the first feed hopper 12, the first discharge hopper 13 and the second discharge hopper 15.

[0060] When processing rice raw materials, the raw materials are first put into the second feed hopper 16 and fall naturally onto the surface of the screening plate 17 inside the second feed hopper 16. The rice raw materials are screened by the screening plate 17 to effectively remove large impurities such as straw, gravel, and lumpy rice mixed in with the raw materials, prevent various impurities from accumulating and adhering to the surface of the screening plate 17, avoid screen hole blockage, and ensure that the rice raw material screening operation is continuous and stable.

[0061] To achieve automated and continuous anti-clogging and impurity removal, two drive wheels 2 installed at the sliding slots 26 on both sides of the second feed hopper 16 operate synchronously. The rotating drive wheels 2 drive the inner connected rotating rod 21 to rotate at a constant speed, which in turn drives the sleeve 22 fixed on the outer side of the rotating rod 21 to rotate synchronously. The outer side of the sleeve 22 is symmetrically and integrally arranged with multiple sets of front digging shovels 221 and rear digging shovels 222. With the sleeve 22, it makes continuous circumferential rotation, which can continuously and dynamically shovel and clean large impurities that are retained and accumulated on the surface of the screening plate 17. This effectively removes the impurities accumulated on the surface of the screening plate 17 and avoids impurities blocking the upper surface of the screening plate 17 and the screen holes. Therefore, it solves the defect of easy material blockage in the feeding and screening process of traditional rice hullers to a certain extent.

[0062] During the continuous rotation of the rotating rod 21, the irregularly shaped cross mounting plate 4 located between the drive wheel 2 and the sleeve 22 can be driven to rotate synchronously. Relying on the special structure of the irregularly shaped cross mounting plate 4 and the transmission adaptation of the sliding ball 42 and the rolling bearing 421, the positioning rod 422 can be driven to perform vertical reciprocating motion. The positioning rod 422 is connected to the connecting rod 25, thereby driving the connecting rod 25 to complete the vertical reciprocating movement synchronously. The transmission direction is reversed by the swing arms 251 symmetrically assembled on both sides of the connecting rod 25. Finally, the front collecting plate 3 and the rear collecting plate 31 connected to the swing arms 251 are driven to perform reciprocating horizontal movement along the track 32, realizing the dynamic opening and closing operation of the collecting plates.

[0063] When the front collecting plate 3 and the rear collecting plate 31 move to a position that fits against the side wall of the sleeve 22, they can accurately receive large impurities scooped up by the front dig shovel 221 and the rear dig shovel 222, realizing the immediate collection and aggregation of impurities and preventing impurities from scattering and flowing back; when the two sets of collecting plates move in opposite directions and detach from the side wall of the sleeve 22, passage space can be reserved for the front dig shovel 221 and the rear dig shovel 222 that have completed the scooping operation to pass smoothly, and at the same time, the next set of integrated front dig shovel 221 and rear dig shovel 222 can rotate to the top of the screening plate 17 to repeat the impurity scooping and cleaning operation.

[0064] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

Step 4: The irregular cross mounting plate (4) is used in conjunction with ball bearings to drive the connecting rod (25) and swing arm (251) to drive the two sets of collecting plates to open and close along the track (32) to accurately receive the impurities scooped up by the digging shovel and prevent the impurities from scattering and flowing back. Step 5: The rice raw material after screening and purification enters the equipment for rice hulling. The finished rice is discharged from the first discharge hopper (13), and the collected impurities are discharged through the second discharge hopper (15), thus completing the entire rice screening and anti-clogging processing process.
