Description

Technical Field

[0001] The utility model belongs to the technical field of straw processing, and in particular relates to an air suction type straw dust removal and sorting device. Background Art

[0002] Straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (usually coarse grains) after the seeds are harvested. For example, the existing wheat straw recycling often uses a baler to pack the straw into a cylindrical shape, and then transports the packaged straw to the recycling factory. Before the straw is packaged, it needs to be dusted and sorted to remove impurities and dust in the straw.

[0003] However, at present, when performing dust removal and sorting operations on straw, most of them use vibration equipment to shake out the dust in the straw. However, when shaking off the dust, dust will be generated, and the dust will cause harm to the air and workers, which is inconvenient to use. Utility Model Content

A box door is hinged on one side of the collection box 6, and a sealing strip is installed on the box door.

[0030] In this embodiment, the filter bag 7 is separated by the partition net 9 to ensure that the filter bag 7 does not contact the air suction end of the fan 8, which is conducive to the fan 8 to extract the air in the box 1 and facilitates the operation of the fan 8.

[0031] In a further preferred embodiment of the utility model, the material dispensing mechanism includes: a one-way screw 10 rotatably installed in the box body 1; a slider 11 threadedly sleeved on the one-way screw 10, and the slider 11 is in sliding contact with the top of the inner wall of the box body 1; a first electric telescopic rod 12 fixedly installed at the bottom of the slider 11; a scraper 13 fixedly installed on the output rod of the first electric telescopic rod 12, and the scraper 13 is in sliding contact with the screen plate 3; a servo motor 14 assembled on one side of the box body 1, and the output shaft of the servo motor 14 is fixedly connected to the one-way screw 10.

[0032] In this embodiment, when it is necessary to perform a material shifting operation on materials piled up in one place, first start the servo motor 14 so that the servo motor 14 drives the one-way screw 10 to rotate, and the one-way screw 10 drives the slider 11 to slide along the box body 1. When the slider 11 slides close to the feed hopper 5, start the first electric telescopic rod 12 so that the first electric telescopic rod 12 drives the scraper 13 to slide, and the scraper 13 slides into the material. Then start the servo motor 14 so that the servo motor 14 drives the one-way screw 10 to rotate, and then the slider 11 drives the scraper 13 to slide left and right, and the material is dispersed, so that the material is evenly dispersed on the screen plate 3, which is beneficial to the subsequent material sorting operation.

[0033] In a further preferred embodiment of the present invention, a curved plate 15 is fixedly installed in the box body 1 , and the curved plate 15 is arranged below the one-way screw 10 , and the curved plate 15 is in sliding contact with the slider 11 .

[0034] In this embodiment, the one-way screw 10 is protected by the arc plate 15 , thereby reducing the contact between the one-way screw 10 and dust, which is beneficial to slowing down the wear of the one-way screw 10 and the slider 11 .
