Variable-diameter roller type jerusalem artichoke harvester

Abstract

The invention discloses a variable-diameter roller type jerusalem artichoke harvester, comprising a jerusalem artichoke digging assembly, a roller assembly and a miscellaneous residue separation and tuber collection assembly, wherein the jerusalem artichoke digging assembly, the roller assembly and the miscellaneous residue separation and tuber collection assembly are installed on a rack and are connected into a whole by means of the rack; the jerusalem artichoke digging assembly comprises a digging shovel arranged at the front end of the rack, a belt cross rod type lifting conveyer belt and an eccentric wobble wheel, wherein the belt cross rod type lifting conveyer belt can be used for conveying and is arranged at the front end of the rack in a transmission way, and the eccentric wobble wheel is positioned at the front end of the rack and enables the belt cross rod type lifting conveyer belt to shake up and down; the roller assembly comprises a roller rotatably arranged on the rack, aroller filter screen arranged on the roller, and a spiral ring sheet arranged in the roller filter screen; the miscellaneous residue separation and tuber collection assembly comprises a box body which is arranged at the rear end of the roller and can be opened and closed; the box body is internally provided with a receiving groove insulation baffle plate and an inclined jerusalem artichoke tuberguide groove.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a variable diameter drum type Jerusalem artichoke harvester. Background technique [0002] At present, the mechanized harvesting of Jerusalem artichoke in China mainly uses small and medium-sized potato harvesters for operation. The machine tool structure and operating parameters are all set according to potatoes. , the degree of fragmentation of the soil block is not enough, and the loose soil cannot be screened cleanly, so that when the Jerusalem artichoke tubers are laid on the ground, they mix with the soil blocks, loose soil, and residual roots and fall, and are covered by the soil, making subsequent manual picking impossible. At the same time, it is impossible to separate all the Jerusalem artichoke tubers from the root system, and they fall together with the residual roots. Jerusalem artichoke tubers with smaller diameters fall from the gap between the spokes of the ...

[0002] At present, the mechanized harvesting of Jerusalem artichoke in China mainly uses small and medium-sized potato harvesters for operation. The machine tool structure and operating parameters are all set according to potatoes. , the degree of fragmentation of the soil block is not enough, and the loose soil cannot be screened cleanly, so that when the Jerusalem artichoke tubers are laid on the ground, they mix with the soil blocks, loose soil, and residual roots and fall, and are covered by the soil, so that subsequent manual picking cannot be carried out effectively.

At the same time, it is impossible to separate all the Jerusalem artichoke tubers from the root system, and they fall together with the residual roots

Jerusalem artichoke tubers with small diameters fall from the gap between the spokes of the potato harvester's elevator chain, making it impossible to dig out the Jerusalem artichoke tubers
