[0028] In order to solve the technical problem that the rice bran is adhered to the rice bran collecting hopper due to the fact that the fan 400 cannot suck away part of the rice bran containing moisture, and the rice bran is prone to accumulate on the rice bran collecting hopper after long-term use, the utility model provides a rice bran collecting hopper and a rice polishing machine, which can realize that the air inlet end of the fan 400 can make the gas enter the rice bran collecting hopper along the air inlet hole 210 and the air flow gap 500 while discharging the rice bran in the rice bran collecting hopper, and the gas flowing along the setting direction of the air flow gap 500 can blow away the rice bran adhered to the circumferential inner wall of the hopper body 200, so that the rice bran is prevented from adhering to the circumferential inner wall of the hopper body 200, and further, the rice bran is prevented from accumulating.

[0029] It should be noted that the rice bran collecting hopper and the rice polishing machine are used in but not limited to the technical field of rice processing equipment, in order to facilitate the description, in the utility model, only the application of the rice bran collecting hopper and the rice polishing machine in the technical field of rice processing equipment is taken as an example for description, and the principle of the application of the rice bran collecting hopper and the rice polishing machine in other types of equipment is substantially the same as that in the technical field of rice processing equipment, which will not be described here.

[0030] Please refer to Figures 1 to 5 , Figure 1 , Figure 3 and Figure 5 are structural schematic diagrams of the rice bran collecting hopper and the rice polishing machine in an embodiment of the utility model, the rice bran collecting hopper is connected to the polishing machine body 100, the polishing machine body 100 has a discharge port, and the rice bran collecting hopper comprises a hopper body 200 and at least one air guide assembly 300; the hopper body 200 is connected to the polishing machine body 100, the inside of the hopper body 200 is hollow, and the hopper body 200 has a feeding end and a discharging end which are communicated with the inside of the hopper body 200; the feeding end of the hopper body 200 is communicated with the discharge port, and the discharging end of the hopper body 200 is arranged at the air inlet end connected to the fan 400; at least one air inlet hole 210 is formed in the circumferential side wall of the hopper body 200; the air guide assembly 300 is arranged in the hopper body 200 and connected to the hopper body 200; an air flow gap 400 is formed between the air guide assembly 300 and the inner wall of the hopper body 200; one end of the air flow gap 400 is communicated with the air inlet hole 210, and the other end of the air flow gap 400 extends towards the discharging end of the hopper body 200; and the other end of the air flow gap 500 is open.

[0031] In the device, the feeding end of the hopper body 200 is communicated with the discharge port of the polishing machine body 100, and the discharging end of the hopper body 200 is arranged at the air inlet end connected to the fan 400, so as to discharge the rice bran in the rice bran collecting hopper; the air guide assembly 300 is connected to the hopper body 200 and has the air flow gap 500 extending along the circumferential inner wall of the hopper body 200; one end of the air flow gap 500 is communicated with the air inlet hole 210, and the other end of the air flow gap 500 is open and extends towards the discharging end of the hopper body 200, so as to guide the gas to flow along the extension direction of the circumferential inner wall of the hopper body 200.

[0032] Furthermore, by setting the air flow gap 500, when the air inlet end of the fan 400 discharges the bran powder in the bran collection hopper, gas can enter the bran collection hopper along the air inlet holes 210 and the air flow gap 500, and the gas flowing along the set direction of the air flow gap 500 can blow away the bran powder adhering to the circumferential inner wall of the hopper body 200, preventing the bran powder from sticking to the circumferential inner wall of the hopper body 200, and further avoiding the accumulation of bran powder, which can solve the technical problem in the prior art that due to the fan 400 being unable to suck away some bran powder containing moisture, the bran powder sticks to the bran collection hopper, and after long-term use, bran powder is likely to accumulate on the bran collection hopper.

[0033] In this embodiment, as Figure 1 、 Figure 3 shown, the cross-section of the hopper body 200 is in a "mouth" shape, and the cross-sectional area of the hopper body 200 gradually decreases in the direction away from the discharge port, and it has four inner walls.

[0034] The hopper body 200 is in a trumpet shape, so that the inner wall of the hopper body 200 forms four inner walls that are respectively inclined downward relative to the discharge port of the polishing machine body 100, which is beneficial for the bran powder to slide down along the inclined inner walls.

[0035] Furthermore, four inclined planes are formed inside the hopper body 200, which is beneficial for the gas entering from the air inlet holes 210 and the air flow gap 500 to blow off the bran powder adhering to the circumferential inner wall of the hopper body 200, and can improve the anti-sticking effect of the device.

[0048] In the embodiment, as shown in Figure 2 , the number of air inlet holes 210 in the hopper body 200 is multiple, the multiple air inlet holes 210 are arranged in the width direction of the inner side wall of the hopper body 200, and the multiple air inlet holes 210 arranged in the same width direction of the inner side wall of the hopper body 200 form a group, and multiple groups of air inlet holes 210 are arranged in the extension direction of the inner side wall of the hopper body 200.

[0049] Multiple groups of air inlet holes 210 and multiple gas guide plates 310 are arranged in the extension direction of the inner side wall of the hopper body 200, the multiple gas guide plates 310 divide the inner side wall of the hopper body 200 into multiple sections, each gas guide plate 310 can sweep the inner side wall of each section, and the gas flowing through the gas flow gap 500 is effectively ensured to be sufficient to blow off the bran adhering to the circumferential inner wall of the hopper body 200, and the anti-adhesion effect of the device can be improved.

[0050] In one embodiment, please refer to Figure 3 , a plurality of air guide assemblies 300 are arranged on the inner wall of one side or multiple sides of the hopper body 200.

[0051] According to the use, the air guide plate 310 can be arranged on the inner wall of one side or multiple sides of the hopper body 200, which can effectively ensure that the gas flowing through the air flow gap 500 is sufficient to blow off the bran adhering to the circumferential inner wall of the hopper body 200, thereby improving the anti-adhesion effect of the device.
