Potato classification device

Abstract

The invention discloses a potato classification device. A rolling classification screen is in a hollow cylinder structure formed by connecting annular classification strip bars; the classification strip bars are divided into a classification area A, a classification area B and a classification area C from left to right sequentially according to the densities, arrayed from lower to higher, of the classification strip bars; a fixed feed port is formed in the higher end of a fixed rolling classification screen on a rack; inclined transmission scraping plates are arranged on a lifting device; a fixed material receiving hopper is arranged above the upper ends of the inclined transmission scraping plates; the lower end of the fixed material receiving hopper is connected with a material receivinghose; the material receiving hose communicates with the interior of the fixed feed port; discharging hoppers are arranged below the rolling classification screen; and material receiving devices are arranged below the end parts of the discharging hoppers. The functions of potato transportation, lifting, potato and soil separation and automatic collection are realized, the rolling classification screen is reliable in structure and easy to operate and is practical, potato and soil rapid separation is realized, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of potato harvesting equipment, in particular to a potato grading device. Background technique [0002] Most places in the country are suitable for growing potatoes. Now the country promotes potatoes as the fourth staple food, and it is the main crop variety in our country. Potatoes are not only agricultural crops, but also economic crops. Potatoes show their unique advantages in deep processing. In addition to being eaten as vegetables, they can also be processed into starch, strips, slices, mud, dextrin, vermicelli, etc., which have extremely high economic value. , is the main source of income for growers in the central and western regions. However, with the expansion of the planting area, the harvest of potatoes has become a big problem, requiring a large amount of labor, high labor intensity and long harvest time. Rising labor costs have seriously restricted the income of growers. Potato planting and h...

Problems solved by technology

Due to the large number of harvested potatoes, manual sorting is time-consuming and labor-intensive. Not only the work intensity of the workers is high, the work efficiency is low, but also the randomness is large, and the classification is not standardized.

The existing grading device does not have grading equipment specifically for potato harvesting. On the one hand, the existing vegetable grading machine has low sorting efficiency and is not easy to clean and maintain. On the other hand, it is easy to cause damage to the sorted vegetables during the sorting process. The holes are easy to block, the screening efficiency is low, and the production cost is high.

In addition, the current potato harvesting machines still scatter the dug potatoes on the ground, which does not solve the problem of centralized collection, and still requires manual picking, which results in low work efficiency
