[0002] Rice processing is the process of converting paddy rice into edible rice, which mainly includes cleaning, husking, milling, grading, color sorting and packaging. In this process, the rice is first cleaned and then the husk is removed to obtain brown rice. The brown rice is milled multiple times to remove the bran layer and finally becomes white rice. The white rice is graded according to grain size and quality, and color sorting is used to remove off-color grains to ensure the quality and appearance of the rice. Finally, the rice is weighed and packaged, stored in a dry and ventilated warehouse, and transported to the market when needed. The temperature and humidity must be strictly controlled throughout the entire processing process to prevent the rice from spoiling, and automated equipment is used to improve efficiency and quality.

[0003] The processing of rice requires the use of a vertical rice polishing machine. Although the traditional vertical rice polishing machine has the ability to process rice, it still has some shortcomings. For example, it lacks the ability to filter and remove impurities from the rice before processing, so it is easy for impurities to enter, which not only affects the processing quality of the rice, but also easily causes damage to the equipment. In addition, the structure of its grinding component is relatively fixed, so its grinding specifications are also relatively fixed. Therefore, it is difficult to adjust when there are different grinding requirements, which will cause certain limitations during use. Therefore, a vertical rice polishing machine is proposed to address the above problems. Utility Model Content

[0023] A vertical rice polishing machine comprises a hulling box 1, a fine grinding box 2 is provided below the hulling box 1, the hulling box 1 is arranged with a top open structure, and the bottom of the hulling box 1 passes through the center of the top wall of the fine grinding box 2 and is communicated with the inner cavity of the fine grinding box 2, a filter assembly 3 is provided above the hulling box 1, and a hulling assembly 4 is provided in the inner cavity of the hulling box 1. A filter screen plate 5 is fixedly connected to the inner cavity of the fine grinding box 2, and a fine grinding assembly 6 is provided on the filter screen plate 5. A discharge valve 7 is fixedly connected to the bottom center of the fine grinding box 2 and the discharge valve 7 is communicated with the inner cavity of the fine grinding box 2.

[0024] The filter assembly 3 includes a filter frame 301 that matches the specifications of the top opening of the fine grinding box 2. The two side walls of the filter frame 301 are equidistantly arranged and penetrated by a number of connecting bolts 302. The top two sides of the shelling box 1 are equidistantly arranged and penetrated by a number of connecting screw holes 303 that are equal in number, corresponding in position and matching in specifications to the connecting bolts 302. The filter assembly 3 can have the ability to filter and remove impurities from the rice before processing, so it is not easy for impurities to enter together, which not only provides protection for the processing quality of the rice, but also is not easy to cause damage to the equipment, and its structure is flexible, so it is more convenient when it needs to be replaced or cleaned later; the shelling assembly 4 includes a first motor 401 that is symmetrical and fixedly connected to the rear wall of the shelling box 1, the output end of the first motor 401 penetrates the rear wall of the shelling box 1 and extends to the inner cavity of the shelling box 1 and is fixedly connected to a shelling rubber roller 402, the front end of the shelling rubber roller 402 is rotatably connected to the front wall of the inner cavity of the shelling box 1, and the shelling assembly 4 can hull the rice, thereby preliminarily processing it into brown rice; the fine grinding assembly 6 includes a second motor 601 fixedly connected to the center of the bottom of the filter screen plate 5, and a transmission shaft 602 is fixedly connected to the output end of the second motor 601. The transmission shaft 602 passes through the filter screen plate 5 and extends to the top of the filter screen plate 5. A connecting seat 603 is slidably connected to the transmission shaft 602. The two side walls of the connecting seat 603 are symmetrically and fixedly connected with fine grinding rollers 604. A positioning bolt 605 passes through the center of the front wall of the connecting seat 603. A plurality of positioning screw holes 606 corresponding to the positions of the positioning bolts 605 and matching the specifications are arranged at equal intervals in the longitudinal direction on the transmission shaft 602. The fine grinding assembly 6 can finely grind the brown rice to remove the bran layer and make the rice grains whiter and smoother. In addition, the structure of the fine grinding assembly 6 is relatively flexible, so its fine grinding specifications are also relatively flexible. Therefore, when there are different fine grinding requirements, it can be adjusted, thereby not causing limitations during use.

[0025] Working process: First, power on all electrical appliances and connect them to external controllers. The shelling box 1 can provide space for shelling rice, and the fine grinding box 2 can provide space for fine grinding of brown rice. The filter frame 301 in the filter assembly 3 can filter and remove impurities from the rice through its own mesh before processing, so it is not easy for impurities to enter together, which not only guarantees the processing quality of rice, but also is not easy to cause damage to the equipment. In addition, the installation structure of the filter frame 301 is flexible, so it is more convenient to replace or clean it later. When installing, the filter frame 301 only needs to be removed from the shelling box. The top of the shell box 1 is placed in the shelling box 1. At this time, the hole position of the connecting bolt 302 corresponds to the hole position of the connecting screw hole 303. Finally, it is only necessary to screw the connecting bolt 302 casing into each connecting screw hole 303. Similarly, the shelling assembly 4 can shell the rice, thereby preliminarily processing it into brown rice. When shelling, the first motor 401 is started. The driving directions of the two first motors 401 are opposite, thereby driving the two shelling rubber rollers 402 to rotate relative to each other. When the rice after filtering and impurity removal passes through the two shelling rubber rollers 402, the outer shell of the rice will be peeled off due to friction and extrusion, thereby forming brown rice. The filtered rice The mesh plate 5 can block the brown rice so that it can be filtered out after being finely ground. The fine grinding component 6 can finely grind the brown rice to remove the bran layer and make the rice grains whiter and smoother. In addition, the structure of the fine grinding component 6 is relatively flexible, so its fine grinding specifications are also relatively flexible. Therefore, it can be adjusted when there are different fine grinding requirements, so as not to cause limitations during use. When the brown rice falls on the filter mesh plate 5, the second motor 601 is started, and the second motor 601 drives the two fine grinding rollers 604 to rotate through the transmission shaft 602 and the connecting seat 603, thereby passing through the fine grinding roller 604. 04's own surface abrasive grinds the brown rice it contacts. When there is a need for fine grinding of different specifications and the height of the fine grinding roller 604 is adjusted, first unscrew the positioning bolt 605, so that the fine grinding roller 604 can move in height by sliding longitudinally on the transmission shaft 602 through the connecting seat 603. When the height of the fine grinding roller 604 is adjusted to a suitable position, align the positioning screw hole 606 of a suitable height with the hole position of the positioning bolt 605, and finally screw the positioning bolt 605 into the positioning screw hole 606 for positioning. The discharge valve 7 can discharge the processed rice for subsequent processing.
