Description

A kind of tubers material length grading machine
Technical field
The utility model relates to agricultural product sorting technology field, be specifically related to a kind of tubers material length grading machine, for carrying out length grading to tubers material, the tubers material that relates to is as the material such as potato, sweet potato, may be used for the front length grading to material of storage in postpartum, also can be used for preserving rear or adding the length grading of man-hour to material.
Background technology
China produces the several hundred million ton of the tubers agricultural product such as potato, sweet potato per year, along with the raising of living standards of the people and the needs of overseas market, require more and more higher to the classification of these tubers agricultural product, process and the requirement such as export packing and storage with the selling by grade, the processing that meet tubers agricultural product.
Mainly or rely on and manually complete, the labour of needs is many, works powerful for the sorting of current China tubers agricultural product, and the result of classification because of the individual difference of labourer, difference is comparatively large, the uniformity of classification is poor, and efficiency is lower.
For potato, the manual grading skill that peasant household adopts at the edge of a field is mainly classified by the overall size of potato, sorting is carried out by impression or experience, it is also take into account potato diameter and length two factors that peasant household empirically carries out sorting, makes the potato of the same grade specification sorted out visually close to consistent; And the disadvantage that manual grading skill exists is exactly lack unified operative norm between personnel, different personnel to the operative norm of the fresh potato of same grade specification different and after bringing up classification product not there is uniformity, thus have impact on the price of peasant household's sale, and then have impact on the income of peasant household.
Chinese patent literature CN103111412A discloses a kind of tubers material length grading machine, comprise frame and multiple classification rotating roller be set in parallel in frame, multiple classification rotating roller is arranged along the direction vertical with mass transport direction, multiple classification rotating roller comprises the many sorting cover rollers be intervally installed and catches roller, sorting cover roller rotates along mass transport direction, catching roller and sorting, overlap roller rotation direction contrary, and the rotation external diameter of seizure roller is less than or equal to the rotation external diameter that roller is overlapped in sorting; Sorting cover roller comprises the first power transmission shaft and the first rubber roll, first rubber roll suit is fixed on the first power transmission shaft, multiple rubber sorting bucket is axially formed along the first rubber roll is whole, multiple rubber sorting bucket is uniform along the circumference of sorting cover roller, and rubber sorting bucket is by being placed on the sorting space every dish, the first rubber roll being divided into multiple equal length on the first power transmission shaft.
Realizing in process of the present utility model, utility model people finds that above-mentioned patent document at least exists following problem:
A. actually using, is all promote material by extruding and the mode of to collide to travel forward, do not had once follow-up material or material density little, will cause that material can not advance, original place and roller friction.
B. former hierarchical approaches is because of the irregular diameter of material and length, and motion mode cause classification after the material of various length mix, classification is extremely inaccurate, and classification efficiency is very low.
C. because material motion mode and violent passive collision determines broken skin rate and damage ratio is very high, classification is extremely inaccurate, and classification efficiency is very low.
D. can only by material with a length dimension for line of demarcation is divided into two parts, a part is less than this size, and another part is greater than this size, can not reach and carry out series, unified section by various length requirement, can not meet consumers' demand.
