Description

Technical Field

[0001] The present invention relates to the technical field of screening and conveying equipment, and particularly to a grading and selection machine for agricultural and sideline products. Background Art

[0002] A patent document with the publication number CN221063544U discloses a cottonseed selection device, which includes a selection cylinder. Operation windows are evenly and equidistantly arranged on the side wall of the selection cylinder. A cylinder cover is clamped at the upper end of the selection cylinder, and a driving motor is fixedly installed at the upper end of the cylinder cover. A rotating column is fixedly installed at the output end of the driving motor. Among them, limiting strips are fixedly installed on both side walls of the rotating column; an air separation mechanism is arranged in the inner wall of the selection cylinder. In the scheme, through the design of the selection cylinder, the first air plate, the second air plate, the first retaining ring and the second retaining ring, under the rotation of the first retaining ring, the cottonseeds will be affected by centrifugal force and will be distributed around the outer circle of the first retaining ring. At this time, the air blown out by the second air plate will perform air separation treatment on the cottonseeds. The lighter unqualified cottonseeds will be blown up and, with the cooperation of the first air plate, will be blown towards the inner wall of the selection cylinder and then fall between the first retaining ring and the second retaining ring. The qualified cottonseeds will remain on the first retaining ring to complete the selection, so that the equipment enhances the selection effect of the cottonseeds when in use through the cooperation of screening and air separation; through the design of the selection cylinder, the air disc, the annular groove, the fixed ring and the first threaded ring, when the first threaded ring rotates, it will drive the fixed ring to rotate in the annular groove accordingly. Since the first threaded ring is internally threaded in the selection cylinder, when it rotates, it will adjust the up and down position, and thus can adjust the height of the air disc, achieving the effect of precisely adjusting the wind force.

[0003] The above scheme optimizes and improves the screening of agricultural product cottonseeds. In the prior art, in order to further improve its screening efficiency, a rolling screening method is adopted, and the material is placed into a screening mesh cylinder, and the screening mesh cylinder is rotated by a rotating motor. In the multi-stage screening device in the prior art, when performing screening work, first, the introduction of the material is generally carried out by staff putting the material into the screening mesh cylinder, resulting in poor continuity of its screening work. Moreover, the dust and impurities in the material also need to be pre-cleaned to avoid blocking the screening mesh cylinder; the existing screening devices lack a matching pre-treatment auxiliary mechanism to meet the requirements of agricultural product screening work.

[0037] The number of sets of the air suction box body 708 and the first installation opening 707 is the same, and two air suction box bodies 708 are symmetrically arranged on both sides of the discharge port 702; the number of sets of the collection box 714 and the second installation opening 711 is the same, and one collection box 714 is arranged at the bottom side of the air suction box body 708.

[0038] In this embodiment, the material storage bin 701 in the screening and conveying auxiliary mechanism 7 is arranged above the conveying bench 2. Materials fall from the discharge port 702 at the bottom of the material storage bin 701 onto the conveyor belt 3, and then the materials are conveyed to the screening drum device 1 for the selection work. During this process, the materials to be screened and processed are stored in the material storage bin 701, which can realize the continuous conveying of materials, thereby improving the continuity of the material screening work and having a positive effect on improving the screening work efficiency. Moreover, an auxiliary rotating cylinder 705 is arranged in the discharge port 702 and dispersion strips 706 are arranged on the auxiliary rotating cylinder 705, which has a dispersion effect on the falling materials, avoiding the condensation phenomenon and contributing to the normal progress of the subsequent screening work. Here, two auxiliary rotating cylinders 705 are symmetrically arranged in the discharge port 702, and the number of sets of the auxiliary rotating cylinders 705 is the same as that of the rotation control motors 704. While the dispersion strips 706 on the auxiliary rotating cylinder 705 disperse the materials to avoid condensation, they can also cooperate with the air suction box bodies 708 arranged on both sides of the discharge port 702 to suck air through the air suction pipe body 710 to adsorb the dust and impurities in the materials. The functions in this process are, on the one hand, to improve the quality of the screening work and minimize the mixing of dust and impurities in the product; on the other hand, to avoid the problem that the dust and impurities in the materials block the screening drum when the materials are conveyed to the subsequent screening drum device 1, ensuring the stable progress of the screening work.

[0039] Here, the filter box body 712 is placed in the air suction box body 708, and the positions of the filter box body 712 and the collection box 714 are corresponding and the number of sets is the same.

[0041] Two sets of auxiliary rotating cylinders 705 are arranged at the discharge port 702. On the one hand, it aims to improve the efficiency of dispersing and preventing condensation of materials; on the other hand, after the materials are dispersed by the first auxiliary rotating cylinder 705, they then fall onto the second auxiliary rotating cylinder 705 for further dispersing work. During this process, there is also a corresponding buffering effect on the falling materials, that is, it increases the time for dust and impurities in the materials to be sucked out, and further improves the sufficiency of removing dust and impurities.

[0042] When the materials fall from the discharge port 702 onto the conveyor belt 3, the purpose of arranging the conveying auxiliary soft bristles 6 on the conveyor belt 3 is, on the one hand, to have a corresponding auxiliary effect on the conveying work of the materials, to prevent the materials from slipping on the conveyor belt 3 and causing material accumulation; thus avoiding the problem of materials falling from the conveyor belt 3 during the conveying process; on the other hand, it can further adhere to and remove the remaining dust and impurities in the materials.
