Description

Technical Field

[0001] The invention relates to the technical field of rice processing, in particular to rice processing production equipment. Background Art

[0002] Rice processing is the process of converting rice into edible rice, which mainly includes cleaning and pretreatment: removing impurities (such as soil, stones, straw, etc.) in rice to ensure the purity of raw materials; rice hulling: breaking and falling off the rice husk through friction between rubber rollers; rice milling: removing the bran layer on brown rice through milling to obtain white rice; polishing: using a polishing machine to apply a small amount of vegetable oil or water mist on the surface of rice, and then rotating and rubbing at high speed to make it smoother and whiter; grading and selection: classifying rice according to factors such as particle size and completeness to improve product quality. It also includes color sorting and quality inspection of finished rice to improve its appearance quality and nutritional value.

[0003] However, the following problems still exist in the rice husking process: (1) When a large amount of rice flows into the husking area at the same time, it is easy to cause local accumulation. This accumulation not only increases the risk of mechanical damage to the rice surface, but also may lead to uneven distribution of squeezing force, which in turn causes uneven cracking of the rice husk, increases the difficulty of husking and reduces the husking efficiency. In addition, the rice is usually only subjected to one friction husking treatment. Due to the limitations of a single treatment, the husking rate of the rice is not ideal. Some rice may not be completely husked and directly flow to the subsequent processing steps, affecting the effect of the subsequent processing steps.

[0004] (2) The existing rubber rollers have low wear resistance and therefore need to be frequently replaced or repaired. To facilitate the disassembly and assembly of the rubber rollers, threaded connections are commonly used. This installation method requires retightening the threaded connection each time the rubber rollers are replaced, which requires a lot of maintenance time and labor intensity. In addition, during long-term use, the threads may gradually wear out, resulting in a decrease in connection strength, which reduces the working stability of the rubber rollers and subsequently has a significant impact on the rice husking effect and efficiency.

The buffer plates 311 can buffer and slow down the rice entering the fixed shell 1 to avoid a large amount of rice directly reaching the processing position and causing blockage. At the same time, the rice husk on the rice can be loosened or broken in advance through the collision between the rice and the buffer plate 311, thereby improving the subsequent rice shelling effect. The guide plate 313 can ensure that the rice flows accurately to the subsequent processing position, and the rice shelling is completed in an orderly and accurate manner on the basis of ensuring the feeding amount and feeding speed.

The rear ends of the two rotating rollers 32 in the same group of shelling parts rotate through the fixed shell 1 and are respectively installed with a large gear 335 and a small gear 336. The large gear 335 and the small gear 336 in the same group of shelling parts are meshed and the number of teeth of the large gear 335 is greater than the number of teeth of the small gear 336. The large gear 335 and the small gear 336 are alternately distributed in the left and right directions.

[0038] See also Figure 1-Figure 5 A funnel-shaped transition shell 4 is installed at the lower end of the fixed shell 1, and a secondary shelling assembly is arranged inside the transition shell 4.

[0039] See also Figure 2-Figure 6 The fixed housing 1 is provided with a cleaning assembly for cleaning the rubber sleeve 321, and the cleaning assembly includes a mounting plate 34. The left and right side walls of the fixed housing 1 and the lower end of the partition 312 are both provided with mounting plates 34 connected to the fixed housing 1 for sliding forward and backward. The side of the mounting plate 34 close to the rubber sleeve 321 is provided with brushes 341 evenly arranged forward and backward. The front end of the mounting plate 34 passes through the fixed housing 1 and a baffle is installed after the mounting plate 34 is installed. The rear side of the fixed housing 1 is provided with a control member for controlling the forward and backward movement of the mounting plate 34, and the control member includes a control column 34 installed at the rear end of the pinion 336. 2. A connecting rod 343 located above the corresponding control column 342 is installed between the rear ends of the left and right adjacent mounting plates 34. A matching rod 344 is installed at the position of the lower end of the connecting rod 343 corresponding to the control column 342. The control column 342 is provided with two spiral grooves 345 distributed on the left and right sides with respect to the corresponding matching rod 344 and slidingly matched with the matching rod 344. The two spiral grooves 345 are connected to each other at their ends. The rear end of the control column 342 located on the left is connected to the output shaft of the motor 1 346. The motor 1 346 is installed at the rear end of the fixed housing 1 through the support 1.

[0040] The rice that passes through the buffer and the guide member finally flows to the corresponding shelling member, and under the action of the guide plate 313, the rice can accurately enter between the two corresponding rubber sleeves 321. The two groups of shelling members are conducive to improving the shelling efficiency of the rice. Specifically, the motor 346, the pulley 3 and the corresponding belt can cooperate to drive the control column 342 and the small gear 336 to rotate. When the small gear 336 rotates, it drives the large gear 335 meshing with it to rotate synchronously in the opposite direction. Since the number of teeth of the large gear 335 is greater than the number of teeth of the small gear 336, the rotation speed of the large gear 335 is lower than the rotation speed of the small gear 336. At the same time, the large gear 335 and the small gear 336 respectively drive the corresponding rotating roller 32 and the rubber sleeve 321 to rotate synchronously, and the rotating roller 32 and the rubber sleeve 321 in the same shelling member rotate synchronously in the opposite direction. When the rice is sent When the rice enters between two rubber sleeves 321 rotating at different speeds, the rice husk can be smoothly separated from the rice due to the squeezing and friction between the two rubber sleeves 321 and the shear force brought by the differential motion. At this time, the rice can be smoothly husked under the mutual friction between the rubber sleeves 321. In addition, the longitudinal grooves 322 and the annular grooves 323 provided on the rubber sleeves 321 are conducive to increasing the roughness of the surface of the rubber sleeves 321, thereby improving the friction between the rice and the rubber sleeves 321. Regardless of whether the rice is in a vertical, horizontal or inclined state when entering between the rubber sleeves 321, the rice can always be subjected to uniform force during the squeezing and rubbing process. At the same time, the longitudinal grooves 322 and the annular grooves 323 also help the rice to be dispersed into the rubber sleeves 321, avoid the accumulation or uneven distribution of the rice, prevent the rice from being damaged, and thus improve the husking rate of the rice.

[0041] While the shelling assembly is working, the pulley 1 412 drives the pulley 2 413 to rotate synchronously through the belt, and the rotating shaft 41 and the evenly arranged stirring rods 411 rotate synchronously with the pulley 2 413, stirring the rice and rice husks entering the transition shell 4, increasing the activity and uniformity of the rice and rice husks, facilitating more effective rice husk separation in the subsequent process, performing secondary shelling on the frictioned but still unshelled rice, improving the consistency and quality of shelling, and further improving the shelling efficiency of the rice.

[0042] In the process of the above-mentioned rotating roller 32 driving the rubber sleeve 321 to rotate, the left and right control columns 342 rotate synchronously with the corresponding pinion 336. In the process of the rotation of the control column 342, the corresponding matching rod 344 and the connecting rod 343 are driven to move back and forth through two spiral grooves 345 connected end to end. The mounting plate 34 drives the evenly arranged brushes 341 to move back and forth synchronously with the connecting rod 343. Since the rotating roller 32 drives the rubber sleeve 321 to rotate continuously, the brushes 341 that move back and forth can effectively remove the rice or rice husks attached to the annular grooves 323 or the longitudinal grooves 322 on the corresponding rubber sleeve 321, keep the surface of the rubber sleeve 321 clean, ensure its friction and shelling efficiency, maintain it in an effective and good working state, and avoid clogging of the shelling parts. In addition, the guide plate 313 blocking the rotating roller 32 and the rubber sleeve 321 can prevent the cleaned rice or rice husks from splashing upward.
