Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a material distribution device for a grinding mill. Background Art

[0002] Flour mill (also known as flour milling machine) is mainly used to process wheat, corn and other grain crops, grind them into powder, and then separate the flour and bran through sifting. Flour mill is the main equipment for flour milling of wheat, corn and other grain crops. When processing wheat, corn and other grain crops, they need to be transported to designated equipment for processing, and during processing, a material distribution device is needed.

[0003] Due to the irregular growth conditions of grain crops such as wheat and corn, the particle sizes of materials used for grinding also vary. During the grinding process, most materials are poured in a concentrated manner without being screened, which can easily result in poor grinding effects for materials with larger particles. In addition, during material storage, the materials are easily affected by moisture and agglomerate. The existing material distribution device is not convenient for drying and breaking up the damp and agglomerated materials during transportation, is not convenient for screening materials of different particle sizes, and is not convenient for handling dust during transportation, which causes dust to pollute the material distribution environment and affect the health of operators.

[0004] For example, Chinese patent CN213356269U discloses a feed distribution device for multi-line processing of rice, including a buffer bin, a feed neck and a distribution bin. The top of the buffer bin is closed and a feed port is opened. The bottom of the buffer bin is connected to the distribution bin through a contracted feed neck. The bottom of the distribution bin is transversely divided into multiple partitions by a distribution plate, each partition is connected to a discharge port, and the discharge ports are respectively connected to the feed points of the multi-line processing; a rotating shaft is transversely inserted into the side wall of the buffer bin, and a buffer baffle is welded and fixed to the rotating shaft in parallel; a bent rotating handle is fixed at one end of the rotating shaft.

[0005] The feed distribution device for multi-line rice processing has the following disadvantages: although the amount of material distributed to each partition is adjusted by the swing position of the distribution plate, it is impossible to screen materials with different particle sizes, and it is not convenient to break up damp and agglomerated materials, which affects the subsequent grinding efficiency; and it is not convenient to handle dust during the transportation process, so that the dust pollutes the environment and affects the health of operators.

[0006] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

When the material inside the screening frame 1 moves to the left, the material inside the screening frame 1 falls into the discharge pipe 1 through the dividing trough 1 for discharge. When the screening frame 2 moves to the right, the material inside the screening frame 2 falls into the discharge pipe 2 through the dividing trough 2 for discharge. The discharge pipe 1 cooperates with one of the discharge troughs, and the discharge pipe 2 cooperates with the other discharge trough, thereby completing the material distribution work, thereby improving the screening efficiency of the material distribution device for the grinding mill and having a wider adaptability.

[0015] 3.

Under the action of the filter plate, the dust is filtered by the filter holes and adsorbed on the surface of the filter plate. The filtered air is discharged through the exhaust fan, avoiding polluting the material distribution environment and affecting the health of the staff. With the cooperation of the slot and the limit bar, the dust removal plate can be pulled out along the slot through the limit bar, which is convenient for cleaning the filter plate, thereby improving the dust removal efficiency of the material distribution device for the grinding mill and having a wider adaptability.
