Automatic stacker for small potato harvester

Abstract

The invention belongs to the technical field of agricultural machinery, and relates to an automatic stacker for a small potato harvester. The automatic stacker consists of a bar locking hook, a limiting post, a bar locking hook rotating shaft, a driven shaft, poking teeth, a big chain wheel, a drive plate, a stacker box lower cover, a joggling chain driving shaft, a small chain wheel, a chain and a stacker box; the automatic stacker is used with the small potato harvester; and when potatoes are collected, the poking teeth on the drive plate and the big chain wheel rotate together with the rotation of the drive plate and the big chain wheel till the poking teeth are in contact with the bar locking hook, the bar locking hook is pulled to rotate, the self-locking states of the bar locking hook and the stacker box lower cover fail, the stacker box lower cover is opened under the gravity action of the potatoes, and the potatoes are unloaded. After the potatoes are dumped, the bar locking hook and the stacker box lower cover are quickly reset, so that the bar locking hook and the stacker box lower cover can reach the self-locking states again for next stacking. The automatic stacker is suitable for the small and sectional potato harvester.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to an automatic stacker for a small potato harvester. Background technique [0002] Potato is an important root crop and the fourth largest food crop in the world after corn, wheat and rice. According to relevant data, at present, more than 150 countries around the world are planting and developing potatoes, and nearly 200,000 square kilometers of farmland are used to grow more than 5,000 different varieties of potatoes. The global annual output has exceeded 300 million tons. my country is currently the world's largest potato planting country, accounting for 25% of the world's planting area and 58% of Asia's. However, the proportion of potato mechanized production in my country is only 1%, while in developed countries it has reached more than 70%. [0003] Potato harvesting in developed countries generally uses large-scale potato combine harvesters to complete the p...

Problems solved by technology

Due to the need for a lot of manual picking, the harvesting efficiency is low, and it often happens that the machine waits for people or a harvester needs to be equipped with multiple people to pick up

In addition, there is also the problem of low clear potato rate in scattered potatoes
