Description

Technical Field

[0001] The utility model relates to the technical field of grain processing equipment, in particular to a polishing device for grain processing. Background Art

[0002] Grains such as wheat, rice, oats, buckwheat, and millet are primarily consumed in the form of flour and rice products. Rice processing is a fundamental step in the processing of grains, involving large quantities and a wide range of applications. Rice processing involves hulling (husking) the cleaned grains to create brown rice. Milling and kneading are then used to remove the outer pericarp and seed coat, primarily composed of lignin. Surface dust is then removed by brushing and polishing, resulting in a rice product with a clean, shiny surface and intact grains. Some grains have tough outer skins and loose internal structures, making the rice processing process prone to grain breakage, resulting in low yields and significant resource loss. To minimize breakage, repeated light grinding and polishing are now commonly used.

[0003] At present, the Chinese utility model with publication number CN217042704U discloses a polishing device for grain processing, including a box body, a processing mechanism is arranged in the box body, and there are several processing mechanisms that are evenly distributed in the box body from top to bottom. A feed hopper is arranged on the top of the box body, and the output end of the feed hopper is connected with the input end of the processing mechanism at the top, and the output end of the processing mechanism at the top is connected with the input end of the processing mechanism at the middle end through a connecting pipe. The connecting pipes are respectively arranged on the left and right side walls of the box body, and the output end of the processing mechanism at the middle end is connected with the input end of the processing mechanism at the bottom end through a connecting pipe. The processing mechanism also includes a driving and conveying component and a polishing component. The utility model performs multi-stage polishing processing on grains by arranging driving and conveying components and polishing components in multiple processing mechanisms, changes the traditional lifting and conveying setting, and uses a motor to cooperate with a spiral sheet to transport materials, so that the grains are polished multiple times, ensuring the effect of grain polishing and high work efficiency.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it was found that although the above equipment can solve the problem of single function of the existing peeling and polishing equipment when applied, multiple peeling and polishing require multiple lifting and transportation. Therefore, the current situation of grain rice production has many lifting and transportation equipment, long process flow, large floor space, complicated operation, and repeated mechanical contact and impact causing increased invalid damage to products. At the same time, the floating dust generated by peeling and polishing needs to be collected by another separate equipment, which increases the work efficiency of the processing step and makes it impossible to collect while polishing, and cannot meet the production needs. However, during use, when the grain is discharged through the feed hopper, due to the lack of a quantitative discharge structure, the grain cannot be evenly fed into the interior of the polishing box, thereby reducing the polishing quality of the grain.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 3 As shown, the utility model provides a polishing device for grain processing, including a polishing box 1, a feed hopper 2 and a collecting box 3. The feed hopper 2 is connected to the left side of the top of the polishing box 1, and the collecting box 3 is arranged at the bottom of the polishing box 1. The two sides of the inner wall of the feed hopper 2 are fixedly connected with mounting plates 4, the inner wall of the mounting plate 4 is movably connected with a rotating rod 5 through a bearing, the top of the rotating rod 5 is fixedly connected with a baffle plate 6, the top of the mounting plate 4 is fixedly connected with a discharge plate 7, the surface of the discharge plate 7 and the surface of the baffle plate 6 are both provided with discharge holes 8, the bottom of the mounting plate 4 is fixedly installed with a driving assembly 9, and the left side of the top of the baffle plate 6 is fixedly installed with a scraping assembly 10.

[0023] refer to Figure 1 and Figure 2 The driving assembly 9 includes a driving motor 91, which is fixedly mounted on the bottom of the mounting plate 4. The output end of the driving motor 91 is fixedly connected to a bevel gear 1 92. The top of the bevel gear 1 92 is meshedly connected to a bevel gear 2 93. The top of the bevel gear 2 93 is fixedly connected to the bottom of the rotating rod 5.

[0024] As a technical optimization solution of the present invention, by setting up a drive component 9, the mounting plate 4 can effectively fix the drive motor 91, and the drive motor 91 drives the bevel gear 1 92 to rotate. At this time, the bevel gear 1 92 drives the bevel gear 2 93 to rotate the rotating rod 5, and the rotating rod 5 drives the baffle plate 6 to rotate. When the baffle plate 6 rotates and coincides with the discharge hole 8 on the surface of the discharge plate 7, the interior of the collecting box 3 can be quantitatively discharged, so that the grains fall evenly into the interior of the polishing box 1, thereby improving the quality of grain polishing.

[0025] refer to Figure 2and Figure 3 The scraper assembly 10 includes a C-shaped block 101, which is fixedly installed on the left side of the top of the baffle plate 6. A slide rod 102 is fixedly connected to the right side of the inner wall of the C-shaped block 101. A scraper 103 is movably connected to the surface of the slide rod 102. A pressure spring 104 is sleeved on the surface of the slide rod 102. One end of the pressure spring 104 is fixedly connected to the right side of the inner wall of the C-shaped block 101, and the other end of the pressure spring 104 is fixedly connected to the left side of the scraper 103.

[0026] As a technical optimization solution of the present invention, by setting up the scraper assembly 10, the U-shaped block 101 can effectively fix the slide rod 102, and the scraper 103 can slide on the surface of the slide rod 102, and then the scraper 103 is pushed to move by the force of the pressure spring 104, so that the scraper 103 can fit with the inner wall of the feed hopper 2, and then the grain can be scraped, so that the grain is separated from the inner wall of the feed hopper 2, and the grain is prevented from being adsorbed and remaining on the inner wall of the feed hopper 2.

[0027] refer to Figure 2 and Figure 3 The surface of the pressure spring 104 is sleeved with a bellows 11 , one end of the bellows 11 is fixedly connected to the right side of the scraper 103 , and the other end of the bellows 11 is fixedly connected to the right side of the inner wall of the U-shaped block 101 .

[0028] As a technical optimization solution of the present invention, by setting the bellows 11, the scraper 103 and the U-shaped block 101 can be effectively fixed to the bellows 11, and the pressure spring 104 can be covered and protected by the bellows 11 to prevent the grain from contacting the pressure spring 104 and affecting its contraction.

[0029] refer to Figure 2 and Figure 3 An annular groove 12 is provided on the inner wall of the feed hopper 2, and balls 13 are movably embedded on the surface of the baffle plate 6. The number of balls 13 is arranged in several groups and distributed in a ring with equal distances. The surface of the balls 13 is movably connected to the inner wall of the annular groove 12.

[0030] As a technical optimization solution of the present invention, by setting an annular groove 12 and a ball 13, when the baffle plate 6 rotates, the ball 13 will be driven to rotate along with it, so that the ball 13 can slide on the inner wall of the annular groove 12, thereby improving the smoothness of the baffle plate 6 during rotation, reducing the friction between the baffle plate 6 and the feed hopper 2, and improving the service life of the baffle plate 6.

[0031] refer to Figure 1 and Figure 2 A control box 14 is fixedly installed on the front side of the polishing box 1, and the control box 14 is electrically connected to the drive motor 91 through a wire.

[0032] As a technical optimization solution of the present utility model, by setting the control box 14, the control box 14 can effectively control the rotation speed of the driving motor 91. When the driving motor 91 drives the first bevel gear 92 and the second bevel gear 93 to rotate at a relatively high speed, at this time, the rotating rod 5 can drive the baffle plate 6 to increase the rotation speed, thereby increasing the discharging speed of the discharging hole 8. When the rotation speed of the driving motor 91 is adjusted slower, the discharging speed of the discharging hole 8 can be reduced.

[0033] Reference Figure 1 and Figure 2 , a slot hole 15 is opened on the right side of the feed hopper 2, and an observation plate 16 is fixedly connected to the inner wall of the slot hole 15.

[0034] As a technical optimization solution of the present utility model, by setting the slot hole 15 and the observation plate 16, the slot hole 15 can effectively fix the observation plate 16. Through the observation plate 16, it is convenient for the user to observe the inside of the feed hopper 2 so as to understand the discharging state inside the feed hopper 2.

[0035] The working principle and usage process of the present utility model: When in use, first, the user pours the grains into the inside of the feed hopper 2. At this time, the grains fall onto the top of the baffle plate 6. Then, the driving motor 91 is started through the control box 14. Next, the driving motor 91 drives the first bevel gear 92 to rotate. At this time, the first bevel gear 92 drives the second bevel gear 93 to rotate. Then, the second bevel gear 93 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the baffle plate 6 to rotate. When the discharging holes 8 on the surface of the baffle plate 6 coincide with the discharging holes 8 on the surface of the discharging plate 7, at this time, the grains can be discharged through the discharging holes 8, thereby achieving the effect of quantitative discharging inside the polishing box 1, making the grains evenly fall into the inside of the polishing box 1, and improving the quality of grain polishing. When it is necessary to adjust the discharging speed of the grains, at this time, the control box 14 controls the rotation speed of the driving motor 91, so that the driving motor 91 drives the first bevel gear 92 and the second bevel gear 93 to increase the rotation speed. At this time, the rotating rod 5 can drive the baffle plate 6 to rotate faster, so that the discharging holes 8 can coincide as soon as possible, thereby increasing the discharging speed of the discharging holes 8. When the rotation speed of the driving motor 91 is adjusted slower, the discharging speed of the discharging holes 8 can be reduced. When the baffle plate 6 rotates, it will带动 the U-shaped block 101 to rotate along with it. Then, under the action of the compression spring 104, the scraping plate 103 is pushed to move, so that the scraping plate 103 can be in contact with the inner wall of the feed hopper 2, thereby scraping the grains and separating the grains from the inner wall of the feed hopper 2, preventing the grains from being adsorbed and remaining on the inner wall of the feed hopper 2.

[0036] To sum up: this kind of polishing device for grain processing, by setting a blanking plate 7, a baffle plate 6, a discharge hole 8 and a driving component 9, can effectively enable the baffle plate 6 to block the grain, and then the driving component 9 drives the baffle plate 6 to rotate on the top of the blanking plate 7. When the baffle plate 6 rotates one circle so that the slots 15 overlap, the grain will fall into the interior of the polishing box 1 through the discharge hole 8, thereby achieving the effect of quantitative discharge, and solving the problem that when the grain is discharged through the feed hopper, due to the lack of a quantitative discharge structure, the grain cannot be evenly entered into the interior of the polishing box, thereby reducing the polishing quality of the grain.
