Single-side rotary digging type small sweet potato harvester

Abstract

The invention relates to the field of harvesters, in particular to a single-side rotary digging type small sweet potato harvester which comprises a harvesting channel and a harvesting device which are arranged on a vehicle body, the harvesting channel is located on one side of the vehicle body, and a strip-shaped material frame is arranged on the other side of the vehicle body in a horizontal state. The harvesting device comprises a rotary digging mechanism, a transferring mechanism and a spiral conveyor, the rotary digging mechanism, the transferring mechanism and the spiral conveyor are sequentially distributed in the length direction of the strip-shaped material frame, and the spiral conveyor is located at the position, close to the end of the strip-shaped material frame, of the strip-shaped material frame. According to the sweet potato harvesting device, sweet potatoes are harvested through cooperation of the rotary digging mechanism, the transferring mechanism and the spiral conveyor, and due to the fact that the rotary digging mechanism harvests soil along with the sweet potatoes in a rotary digging mode, the soil is effectively separated from the sweet potatoes, the sweet potatoes can be harvested, and the harvesting efficiency of the sweet potatoes is improved. The separation effect of the sweet potatoes and the soil is improved.

Description

technical field [0001] The invention relates to the field of harvesters, in particular to a single-side rotary digging type small sweet potato harvester. Background technique [0002] The sweet potato picking technology adopts a variety of harvesting mechanisms, and there is a common problem of insufficient separation of potato and soil, or the phenomenon of separation and broken skin of sweet potatoes due to vibration during the screening process, which affects sales, and the machine harvester has leakage. The rate is often supplemented by manual picking, which is labor-intensive. At present, when sweet potatoes are collected, the soil will be collected together with the sweet potatoes. When the sweet potatoes are subsequently picked up, manual detection is required, which increases the manpower. labor, and the current harvester moves along the soil where sweet potatoes are planted, and collects sweet potatoes while the harvester is advancing. However, when the sweet potato...

AI Technical Summary

Problems solved by technology

[0004]According to the above-mentioned patent, the sweet potato harvester of this patent is equipped with horizontal springs and vertical springs to perform three-dimensional vibration on the sweet potatoes passing through the vibrating screen, so that the potato and soil are separated However, this patent only solves the separation effect of sweet potato and soil, and fails to solve the situation that the sweet potato is easily missed or crushed when collecting sweet potato, and the patent has no effect on the separation of soil and sweet potato through horizontal vibration. Good, some soil with excessive adhesion cannot be shaken out from the sweet potato, therefore, there is a need for a harvester that collects sweet potatoes from the side of the harvester and improves the separation effect of soil and sweet potatoes
