Diameter grading system for rhizome material

Abstract

The invention discloses a diameter grading system for a rhizome material. The system comprises a rack, a rotating conveying chain, multistage rotating rollers and a material conveying device arranged below the multistage rotating rollers, wherein the multistage rotating rollers comprise a fixed roller and a moving roller which are arranged alternately and form a sorting gap; a fixed roller supporting plate and a moving roller adjusting and supporting plate are arranged at two ends of both the fixed roller and the moving roller respectively and arranged on the chain plates on the same side of the rotating conveying chain; the two ends of the fixed roller rotationally move along horizontal friction rails arranged on the rack; a plurality of gap set devices arranged in the conveying direction of the rotating conveying chain are arranged at two ends of the moving roller respectively; the plurality of gap set devices are relatively fixed and connected with the rack and form an integrated flat guide rail after mutually connected; the flat guide rail is arranged obliquely upwards in the material conveying direction; the sorting gap formed between the fixed roller and the moving roller is continuously enlarged in the conveying direction of the rotating conveying chain; a friction wheel fixedly connected with two ends of the moving roller rolls along the supporting surface of the flat guide rail under the driving of the rotating conveying chain.

Description

technical field [0001] The invention relates to the technical field of agricultural product grading for rhizome materials, in particular to a diameter grading system for rhizome materials, which is suitable for sorting rhizome materials such as potatoes, carrots and onions. Background technique [0002] At present, the main consideration for the classification of rhizome materials is to prevent the materials from being damaged or broken during classification, which will affect their storage period. The existing classifiers, such as Chinese patent document CN202343471U, disclose a diameter classifier for tuber materials, including The frame and the transmission mechanism arranged on the frame, the driving device for driving the movement of the transmission mechanism, the multi-stage parallel grading rollers for screening tuber materials, the feeding hopper, the discharging hopper, the distribution hopper and the The conveying direction of the transmission mechanism is a plura...

Problems solved by technology

[0003] (1) When the material is sorted on the rotating roller, it will directly fall into the area formed by the fixed roller and the two traveling rollers. During the conveying process of the material, due to the rotational force exerted by the rotating roller on the material, the sorted The material usually rolls according to its long axis as the rotation axis. When the traveling roller enters the horizontal sorting area from the transition plate, the sorting gap formed by each horizontal support plate is only one sorting size. The selection adopts a sudden step-by-step sorting method, which will bring the following technical problems: the material sorting position is relatively concentrated, that is, any material between the size of the previous level of sorting and the size of the next level of sorting The materials in the gap are directly sorted out by the sorting gap located at the front end of the next level of horizontal pallets, and most of the sorting gaps formed by the latter level of horizontal pallets have no effect on the sorting of materials

[0004] (2) The above-mentioned patent documents only classify the designed grading series. If the grading series is increased to achieve finer size sorting, this requires a large adjustment and modification of the original equipment, which is laborious and laborious
