Description

Technical Field

[0001] The utility model relates to the technical field of wheat processing, and particularly relates to a sorting device for wheat processing. Background Art

[0002] In wheat processing, it is necessary to sort wheat to remove impurities in the wheat in order to ensure the quality of the flour processed from wheat. After retrieval, in the prior art (application number: CN202222838703.4), a sorting device for wheat processing is described. It is recorded in the text that "during the up-and-down movement of the dust extraction box, the connecting pipe and the ventilation pipe can both contract or stretch to collect the dust in the sorting cylinder, improving the sorting effect of wheat. During the rotation of the stirring shaft, the staff then turns on the dust extraction pump, so that the connecting pipe below the dust extraction box sucks the floating dust or particles inside the sorting cylinder into the ventilation pipe, and then sucks the dust into the collection box. Subsequently, after double filtration through the upper and lower filters, the air finally discharges from the exhaust pipe, and the dust attached to the surface of the wheat remains inside the collection box". However, in the prior art, when the wheat in the sorting cylinder moves to the pipeline below the dust extraction box along with the rotation of the stirring shaft, the connecting pipe below the dust extraction box is prone to accidentally sucking wheat and blocking the dust suction port. Content of the Utility Model

[0003] In order to overcome the defects of the prior art, a sorting device for wheat processing is provided to solve the problem that in the prior art, when the wheat in the sorting cylinder moves to the pipeline below the dust extraction box along with the rotation of the stirring shaft, the connecting pipe below the dust extraction box is prone to accidentally sucking wheat and blocking the dust suction port.

[0004] To achieve the above object, a sorting device for wheat processing is provided, including: a wheat sorting machine body and a sorting rotating cylinder. The inner side wall of the wheat sorting machine body is connected with a sorting rotating cylinder through a rotating disk.

[0005] A dust collection box is installed on the front surface of the wheat sorting machine body. The side end of the dust collection box is communicated with the dust guiding cavity of the dust removal conduit through a dust suction pipe. The dust removal conduit penetrates through the middle of the sorting rotating cylinder. A branch plate is welded on the outer pipe surface of the dust removal conduit. Dust suction mesh surfaces are arranged on the left and right side surfaces of the branch plate. Strip-shaped scraping plates are fixed on the inner cylinder walls on the front and rear sides of the sorting rotating cylinder. The side ends of the strip-shaped scraping plates are in contact with the dust suction mesh surfaces.

[0006] Further, a feeding port is arranged on the upper end surface of the wheat sorting machine body, a discharging port is arranged on the lower surface of the wheat sorting machine body, and rotating disks are welded on the left and right side surfaces of the sorting rotating cylinder.

[0007] Further, a stepping motor is fixed on the left side end of the wheat sorting machine body. The side end of the stepping motor is connected with the left sorting rotating cylinder of the sorting rotating cylinder through a gear transmission assembly.

[0008] Further, the outer end of the dust removal duct is connected through a bearing to a rotating disk in a penetrating manner. Both the left and right ends of the dust removal duct are connected to dust suction pipes, and a powerful dust suction air pump is installed on the surface of the dust suction pipes.

[0009] Further, the surface of the sorting drum is provided with sorting holes distributed in a ring shape, and a material guiding port is arranged in the middle of the lower surface of the sorting drum; and the material guiding port is located above the discharge port.

[0010] Further, the inner wall of the upper end of the wheat sorting machine body is connected to a fixing plate through an electric push rod, and a hole dredging column is adhered to the lower surface of the fixing plate.

[0011] Further, the dust removal duct, the branch plate, the dust suction mesh surface, and the dust suction pipes form a built-in dust suction mechanism of the sorting drum.

[0012] The beneficial effects of the present utility model are as follows. The sorting device for wheat processing of the present utility model utilizes the dust removal duct penetrating through the middle of the sorting drum. Through the powerful dust suction air pump, the branch plate mesh surface outside the dust removal duct sucks the dust and small-volume impurities raised during the rotational sorting of the sorting drum into the dust guiding cavity and discharges them. At the same time, the strip-shaped scraping plate on the inner barrel wall of the sorting drum scrapes off the wheat adsorbed on the branch plate mesh surface, facilitating more efficient and sufficient suction of the dust and small-volume impurities in wheat sorting, avoiding the dust suction mesh surface being covered and blocked by the accidentally sucked wheat, facilitating the sorting of small-volume and large-volume impurities in wheat, and improving the sorting effect of the wheat sorting device.

[0018] Referring to Figures 1 to 4 As shown, the utility model provides a sorting device for wheat processing, including: a wheat sorting machine body 1 and a sorting rotating cylinder 3. The inner side wall of the wheat sorting machine body 1 is connected with the sorting rotating cylinder 3 through a rotating disk 32.

[0019] A dust collection box 2 is installed on the front surface of the wheat sorting machine body 1. The side end of the dust collection box 2 is connected with the dust guiding cavity 42 of the dust removal conduit 4 through a dust suction pipe 21. A dust removal conduit 4 penetrates through the middle of the sorting rotating cylinder 3. A branch plate 41 is welded on the outer pipe surface of the dust removal conduit 4. Dust suction mesh surfaces 43 are arranged on the left and right side surfaces of the branch plate 41. Strip-shaped scraping plates 34 are fixed on the inner cylinder walls of the front and rear sides of the sorting rotating cylinder 3. The side ends of the strip-shaped scraping plates 34 are in contact with the dust suction mesh surfaces 43.

[0020] First, the material guiding port 33 of the sorting rotating cylinder 3 is oriented towards the feeding port 11 of the wheat sorting machine body 1. Wheat is poured into the sorting rotating cylinder 3 and the material guiding port 33 is blocked. Then, the stepping motor 13 is controlled to drive the sorting rotating cylinder 3 to rotate and sort. While sorting, the powerful dust suction air pump 22 is started, so that the mesh surfaces of the branch plates 41 arranged in sequence from top left to bottom right on the outer side of the dust removal conduit 4 suck and remove the dust and small-volume impurities raised in the sorting rotating cylinder 3, and the sorting rotating cylinder 3 is conveyed into the dust collection box 2. At the same time, when the sorting rotating cylinder 3 rotates, the strip-shaped scraping plates 34 in the sorting rotating cylinder 3 scrape off the wheat adsorbed by the dust suction mesh surfaces 43, avoiding the wheat covering and obstructing the dust suction mesh surfaces 43. Finally, the sorted wheat is discharged from the discharging port 12 of the wheat sorting machine body 1.

[0022] As a preferred implementation mode, the feeding port 11 is convenient for pouring wheat from the material guiding port 33 of the sorting rotating cylinder 3 into the cylinder. The stepping motor 13 drives the rotating disk 32 and the sorting rotating cylinder 3 to rotate through the gear transmission assembly 14, and the stepping motor 13 can adjust and control the rotating speed and rotating angle of the sorting rotating cylinder 3.

Dust suction pipes 21 are connected to both the left and right ends of the dust removal conduit 4, and a powerful dust suction air pump 22 is installed on the surface of the dust suction pipes 21.

[0024] As a preferred embodiment, the dust removal duct 4 is in a non-rotating state, and the outer sorting rotating cylinder 3 is driven by the rotating disk 32 to rotate and sort wheat. The powerful dust extraction air pump 22 sends the impurities and dust inhaled into the cavity of the dust removal duct 4 into the dust collection box 2 through the dust suction pipe 21.

[0025] In this embodiment, the sorting holes 31 are annularly distributed on the surface of the sorting rotating cylinder 3, and a material guiding port 33 is arranged in the middle of the lower surface of the sorting rotating cylinder 3; and the material guiding port 33 is located above the discharge port 12.

[0026] As a preferred embodiment, the sorting holes 31 facilitate sorting and discharging wheat, leaving larger particle impurities inside the sorting rotating cylinder 3, while smaller impurities are sucked out by the mesh surfaces of multiple groups of branch plates 41 inside the sorting rotating cylinder 3. The material guiding port 33 serves the functions of feeding and discharging.

[0027] In this embodiment, the upper inner wall of the wheat sorting machine body 1 is connected with a fixing plate 51 through an electric push rod 52, and a hole position dredging column 5 is bonded to the lower surface of the fixing plate 51.

[0028] As a preferred embodiment, the electric push rod 52 pushes the hole position dredging column 5 on the lower surface of the fixing plate 51 to move downward, dredge the sorting holes 31 of the sorting rotating cylinder 3, and extrude the impurities or wheat blocked in the holes.

[0029] In this embodiment, the dust removal duct 4, the branch plate 41, the dust suction mesh surface 43 and the dust suction pipe 21 constitute the built-in dust suction mechanism of the sorting rotating cylinder 3.

[0030] As a preferred embodiment, the built-in dust suction mechanism of the sorting rotating cylinder 3 facilitates more efficient and sufficient suction of dust and small-volume impurities in wheat sorting, avoids the dust suction mesh surface 43 being covered and blocked by accidentally sucked wheat, facilitates sorting out small-volume and large-volume impurities in wheat, and improves the sorting effect of the wheat sorting equipment.
