Picking table assembly for potato harvester

Abstract

A picking table assembly for a potato harvester comprises a picking table, a chain harrow, a primary screening feeding device and seedling cutting devices, wherein the chain harrow is rotatably connected to the interior of the picking table, the primary screening feeding device is installed at the bottom of the feeding end of the picking table, and n-shaped fixing frames are fixedly connected to the two vertical side walls of the feeding end of the picking table in a bridging manner; a first power unit for providing rotating power for the chain harrow and a second power unit for providing rotating power for the primary screening feeding device are arranged on the side wall of the picking table; and the seedling cutting devices are symmetrically arranged at the two sides of the n-shaped fixing frames, and drip irrigation pipe guide steel rings are symmetrically and fixedly arranged at the two side walls of the seedling cutting devices and the two side walls of the picking table. According to the picking table assembly for the potato harvester, potato seedlings at the two sides of the picking table are cut off through the seedling cutting devices; deep potatoes in soil is dug by theprimary screening feeding device, and primarily screening of the potato seedlings and the soil is achieved; and the potatoes, the potato seedlings and the soil are conveyed, separated and screened bythe chain harrow, so that the harvesting rate of the potatoes is effectively improved, and the skin integrity of potato harvesting is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a potato harvester, in particular to a pick-up table assembly for a potato harvester. Background technique [0002] The potato harvester is an automatic agricultural harvesting machine that can dig potatoes out of the soil and perform processes such as harvesting, shaking the soil, separating stems, and removing debris, which greatly reduces the burden on farmers. At present, when most of the potato harvesters are working, there are scattered potato vines outside the two sides of the picking table (working width), which makes it difficult to pick up the potatoes, resulting in a low potato harvest rate and unearthed rate, and the potatoes will be destroyed by the potato vines. Pulled and rolled to both sides of the pick-up platform, resulting in pick-up loss and damage to the potato surface; and because the soil depth of potatoes grows at different levels, existing ...
