Description

Technical Field

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

[0002] Grain processing polishing equipment is a widely used equipment in the grain processing industry. Grain polishing equipment plays an important role in the field of grain processing, and its quality and technical level directly affect the quality and added value of grain.

[0003] The patent publication number CN219849743U discloses a polishing machine for highland barley rice processing, in which water in a water tank is used to spray highland barley rice through a spray plate, and a driving motor is started to drive a driving shaft to rotate, so that the driving shaft drives the polishing frame to rotate and then the polishing roller polishes the highland barley rice, and a rotating motor is started to drive the polishing cylinder and the polishing roller to rotate in opposite directions to further improve the polishing effect.

[0004] The polishing machine sprays the water in the water tank on the highland barley rice pile to be polished. In order to prevent the highland barley rice from deteriorating or rotting during transportation or storage, the highland barley rice is air-dried before polishing, so that the highland barley rice is very dry. Spraying water on the highland barley rice pile will cause multiple highland barley rice to clump, so that no water film is formed on the surface of some highland barley rice, resulting in friction heat between the highland barley rice and the polishing stick and the polishing cylinder during the polishing process, causing the polishing machine to overheat, affecting its service life, and causing wear on the highland barley rice, thereby reducing the quality of the polished highland barley rice. Utility Model Content

[0005] In view of the problem that the grain cannot be uniformly mixed with water and form a water film during polishing, which causes the equipment to overheat, the utility model is proposed.

[0031] The polishing component 2 includes a separation plate 21 disposed in the middle area of ​​the frame 1, polishing plates 22 disposed on both sides of the separation plate 21, and flannel 221 disposed on the sides of adjacent polishing plates 22 close to each other;

[0032] A cavity is provided inside the separation plate 21, a water inlet pipe is connected to the lower end of the separation plate 21, a water pump is connected to the other end of the water inlet pipe, a water tank is connected to the other end of the water pump, water in the water tank is pumped into the cavity by the water pump, the water inlet pipe is connected to the interior of the cavity, an array of water outlet holes are provided on the surface of the separation plate 21, and the water outlet holes are connected to the interior of the cavity, water droplets 211 are provided in the water outlet holes, and a plurality of water grooves 212 are provided on the surface of the water droplets 211. Due to the obstruction of the water droplets 211, the water inside the cavity cannot be quickly discharged, so that the air inside the cavity is discharged through the gap between the water droplets 211 and the water outlet holes, so that the cavity is filled with water.

[0033] During use, the grain to be polished is put into the feed hopper 12, and then the grain is guided by the feed hopper 12 and discharged from the lower end of the feed hopper 12;

[0034] At this time, the two adjacent polishing plates 22 are moved so that the grain contacts the flannel 221 provided on one side of the polishing plate 22, and the flannel 221 cooperates with the dividing plate to make the grain particles roll, and at the same time, the grain particles rub and move the water droplets 211, so that the water droplets 211 rotate in the water outlet, and then the water trough 212 brings out the water inside the cavity, and the water brought by the water droplets 211 fully contacts and mixes with the grain particles, so that a layer of water film is formed on the surface of the grain particles, and the surface of the grain particles is treated by the continuous friction of the flannel 221.

[0035] Example 2

[0036] Reference Figure 4-7 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0037] A support rod 222 is arranged at one end of the polishing plate 22, a limit plate 13 is arranged at one end of the frame 1, a plurality of limit grooves are arranged at the upper end of the limit plate 13, and rollers 131 are rotatably installed at the bottom of the plurality of limit grooves, an extension rod 223 is arranged at one end of the polishing plate 22 away from the support rod 222, and a clamping plate 224 is arranged at the other end of the extension rod 223.

[0038] A mounting platform is provided at one end of the frame 1 away from the side panel 11, slide rails are provided on both sides of the mounting platform and sliders are slidably provided on the slide rails, a clamping block 14 is provided on the top of the slider, a clamping plate 224 is clamped with the clamping block 14, and bolts are provided on the surface of the clamping plate 224 for fixing the clamping plate 224 with the clamping block 14.

[0039] During use, when the polished grains need to be replaced, in order to ensure the polishing effect of the grains;

[0040] By rotating the bolts, the clamping plate 224 can slide on the clamping block, and then the support rod 222 is adjusted to the limiting groove on the limiting plate 13 so that the distance between two adjacent polishing plates 22 is adjusted. Then, the bolts are tightened so that the clamping plate 224 is fixedly connected to the clamping block again. At this time, the grain particles can be put into the hopper so that the replaced grain particles can be effectively polished.

[0041] The remaining structures are the same as those of Example 1.

[0042] Example 2

[0043] Reference Figure 1-7 , which is the third embodiment of the present utility model, and this embodiment is different from the second embodiment in that:

[0044] A ram horn frame 15 is arranged on the upper surface of the mounting table, a ram horn frame 2 16 is arranged at the rear end of the ram horn frame 15, a motor is arranged at the end of the ram horn frame 2 16 away from the ram horn frame 15 and a screw rod 161 coaxially connected to the motor output shaft, and the screw rod 161 penetrates the ram horn frame 15, a gear rotates in the middle of the ram horn frame 15, the screw rod 161 is engaged with the gear, a moving rod 151 is arranged on both sides of the gear, the moving rod 151 is connected to the clamping block 14 at one end away from the gear, the central axis of the gear penetrates the moving rod 151 and the ram horn frame 15, an eccentric disk 17 is arranged at the eccentric part of the gear, a power groove 1511 is arranged on one side of the moving rod 151, the eccentric disk 17 is arranged in the power groove 1511, and the edge of the eccentric disk 17 is tangent to the groove wall of the power groove 1511.

[0046] During use, the motor output shaft drives the screw 161 to rotate, thereby the gear drives the eccentric disk 17 to rotate in the power slot 1511. Since the eccentric disk 17 is located at the eccentric point of the gear axis, the moving rod 151 makes a linear reciprocating motion back and forth, so that the two adjacent polishing plates 22 move synchronously, and then the grain particles between the polishing plate 22 and the separation plate 21 are rubbed and rubbed to achieve polishing of the grain particles. The polished grain particles will fall onto the screen 18. At this time, the impurity powder generated during the polishing process of the grain particles will be filtered through the holes of the screen 18, and the impurities and powder will be collected through the collection box at the lower end of the screen 18, and then they will be centrally processed to avoid pollution to the environment. At the same time, the grain that has been filtered of impurities will slide to one side and be collected under the action of its own gravity through the inclination angle of the screen 18.
