Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to a feeding mechanism for a wheat flour mill which is convenient for screening. Background Art

[0002] A flour mill is a wheat processing machine that relies on external power (such as power generated by an electric motor) to grind wheat into small particles and separate flour particles of different sizes by adjusting the size of the sieve holes to obtain small flour particles. After the wheat is harvested and dried, it needs to be ground into flour by a flour mill. Due to the current limitations of the degree of agricultural mechanization in my country, farmers in most areas dry wheat manually. During the manual drying process, small particles of dust and large particles of impurities are easily mixed into the wheat particles. Although the wheat needs to be cleaned and dried twice before grinding, the mixing of fine particles of dust and large particles of impurities in the wheat particles cannot be avoided.

[0003] The existing wheat mill has the following deficiencies in the feeding process:

[0004] The existing feeding mechanism does not include a screening structure and cannot simultaneously screen out small and large particles of impurities, resulting in the impurities mixed in the wheat grains entering the mill together with the wheat grains, thereby affecting the quality of the flour. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a feeding mechanism for a wheat flour mill that is convenient for screening, which overcomes the deficiencies in the prior art and effectively solves the problem that the prior art cannot simultaneously screen out impurities of small particles and large particles, resulting in impurities mixed in wheat grains entering the flour mill together with the wheat grains, thereby affecting the quality of flour.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A feeding mechanism for a wheat flour mill that is convenient for screening comprises a square tube, a mounting frame is plugged and fixed to the outer wall of one side of the square tube, and a fan is installed in the mounting frame, a dust outlet frame is plugged and fixed to the outer wall of the other side of the square tube, and a screening component is connected to the top of the square tube, the screening component comprises a feed hopper, a coarse filter fixed to the top of the inner wall around the feed hopper, a collecting box connected to one end of the feed hopper, and a vibrating component fixed to the outer walls on both sides of the feed hopper, the vibrating component comprises a first connecting block, a connecting rod fixed to the top of the first connecting block, a telescopic spring movably sleeved on the rod wall of the connecting rod, a second connecting block located at the top of the telescopic spring and movably plugged with the connecting rod, and a limiting block fixed to the top of the connecting rod.

[0008] Pour the raw materials into the top of the feed hopper, and the wheat grains and small particles of dust fall into the square tube through the coarse filter. The feed hopper and the coarse filter are vibrated by the vibration motor, so that the large particles of impurities gradually pass through the opening of the feed hopper and fall into the collection box as the coarse filter shakes. The wheat grains and small particles of impurities falling in the square tube are blown by the fan to the dust outlet frame on the other side of the square tube during the falling process, so that the small particles of impurities are blown out of the dust outlet frame, and the fine filter can effectively prevent the wheat grains from being discharged through the dust outlet frame.

[0009] Preferably, the bottom of the dust outlet frame is an inclined structure, and a fine filter is fixed to the opening of one end of the dust outlet frame away from the square tube.

[0010] The internally inclined dust outlet frame and the fine filter can effectively prevent wheat grains from being discharged through the dust outlet frame.

[0011] Preferably, an opening is provided at one end of the top of the feed hopper, and the opening is flush with the coarse filter screen.

[0012] Large particles of impurities are screened through a coarse filter and made to fall into a collection box from the opening.

[0013] Preferably, a fixing block is fixed to the outer wall at one end of the feed hopper, and symmetrically distributed jacks are provided on the outer wall at one side of the fixing block.

[0014] The collecting box on one side is connected via a fixing block.

[0015] Preferably, fixing rods are fixed to both ends of the outer wall of one side of the collection box, and the fixing rods are plug-fitted with the insertion holes.

[0016] By plugging the fixing rod into the socket, it is convenient to disassemble and assemble the collecting box connected to one side of the feed hopper, which is beneficial to cleaning the large particles of impurities in the collecting box.

[0017] Preferably, the first connecting block is connected and fixed to the outer wall of the square tube, and the second connecting block is connected and fixed to the outer wall of the feed hopper, and a vibration motor is installed on the top of one of the second connecting blocks.

[0018] The feed hopper and the coarse filter are vibrated by a vibration motor to complete the initial screening.

[0019] The beneficial effects of the utility model are:

[0020] The raw materials are poured into the top of the feed hopper, and the wheat grains and small particles of dust fall into the square tube through the coarse filter. The feed hopper and the coarse filter are vibrated by the vibration motor, so that the large particles of impurities gradually pass through the opening of the feed hopper and fall into the collection box as the coarse filter shakes. The fan blows air to the dust outlet frame on the other side of the square tube to blow the small particles of impurities out of the dust outlet frame, and the fine filter can effectively prevent the wheat grains from being discharged through the dust outlet frame, which effectively solves the problem that the prior art cannot simultaneously screen out small and large particles of impurities, resulting in the impurities mixed in the wheat grains entering the mill together with the wheat grains, thereby affecting the quality of the flour.
