[0024] As a technical optimization scheme of the utility model, through setting collecting mechanism 6, when the dust generated in the process of pouring the raw materials in the raw material hopper 3 into the surface grinding machine is sucked into the collecting box 62, the air suction pump 61 is started, the air in the collecting box 62 is sucked outwards, and then the air is transmitted through the pipeline, so that the dust collection pipe 5 supplements the air into the collecting box 62, and thus the dust generated in the process of pouring the raw materials in the raw material hopper 3 into the surface grinding machine is sucked into the collecting box 62, thereby facilitating the user to collect the dust.

[0025] Reference Figure 3 The inside of the collecting box 62 is provided with a filter core 7, and the filter core 7 is connected with the input end of the air suction pump 61.

[0026] As a technical optimization scheme of the utility model, when the dust is sucked into the collecting box 62, the dust gradually approaches the input end of the collecting box 62, and then is blocked by the filter core 7, so that the dust is prevented from entering the inside of the air suction pump 61 to intensify the abrasion of the parts in the inside of the air suction pump 61 and cause damage, thereby prolonging the service life of the air suction pump 61.

[0027] Reference Figure 3 The top of the filter core 7 is fixedly connected with a first magnetic ring 8, the top of the inner wall of the collecting box 62 is fixedly connected with a second magnetic ring 9, and the top of the first magnetic ring 8 is magnetically adsorbed with the bottom of the second magnetic ring 9.

[0031] Reference Figure 2 The inner wall of the collecting box 62 is movably connected with the concentrating box 11, and the front surface of the concentrating box 11 is in contact with the back surface of the box door 63.

[0032] As a technical optimization scheme of the utility model, when the dust is sucked into the collecting box 62 and the suction pump 61 is closed, the dust will gradually fall into the concentrating box 11, and when the dust in the collecting box 62 needs to be cleaned, the concentrating box 11 can be directly taken out for cleaning by opening the box door 63, thereby improving the convenience of the user when cleaning the collecting box 62.

[0034] As a technical optimization scheme of the utility model, when the box door 63 and the collecting box 62 are closed, the rubber pad 12 will be extruded by the box door 63 and the collecting box 62 and deformed, thereby reducing the gap between the closed parts, preventing the suction pump 61 from weakening the suction force of the dust suction pipe 5 when the air in the collecting box 62 is sucked out, and improving the stability of the suction force of the dust suction pipe 5.

[0035] The working principle and usage process of this utility model are as follows: When raw materials need to be transported into the flour mill, the raw materials are first placed into the raw material hopper 3. Then, the conveyor belt 2 is started to drive the raw material hopper 3 to move. Next, the air pump 61 is started to draw the air out of the collection box 62. Then, through the transmission of the conduit, the dust suction pipe 5 replenishes the air into the collection box 62, thus generating suction force in the dust suction pipe 5. Subsequently, when the raw material hopper 3 containing flour raw materials reaches the bend on the right side of the conveyor belt 2, as the raw material hopper 3 gradually tilts, the dust suction pipe 5 simultaneously sucks the dust generated during the process of pouring the flour raw materials into the flour mill into the collection box 62 for centralized collection. This prevents the dust from spreading everywhere, polluting the working environment, and affecting the construction of surrounding workers, thus possessing the advantage of dust suppression.

[0036] In summary, this flour mill's material conveying device, by incorporating a dust suction pipe 5, activates the collection mechanism 6 when raw materials from the hopper 3 are poured into the flour mill. This generates suction through the dust suction pipe 5, drawing in the dust generated as the raw materials are poured out of the hopper 3. This effectively suppresses dust dispersion and solves the problem of dust mixed in with flour raw materials being dispersed during the pouring process, which seriously affects the surrounding air quality and environmental hygiene. Furthermore, this dust can be inhaled by nearby workers, potentially causing respiratory infections.
