Loss-reducing laying and gathering device of double-shaking separation potato harvester

Abstract

The invention provides a loss-reducing laying and gathering device of a double-shaking separation potato harvester. The loss-reducing laying and gathering device comprises a rack, a floating device, asoil pressing device, a double-shaking device and a driving device, and is characterized in that the rack comprises a longitudinal beam, a transverse beam, a stand column and a vertical plate; the floating device comprises a mounting plate, a rotary table, a floating disc and floating frames; two round holes are formed in two ends of the mounting plate in the shape of a rectangular flat plate along the length direction, wherein the sizes of the round holes are different, and axes of the round holes are perpendicular to a rectangular plate surface; two ends of a soil pressing roller which is cylindrical are supported at tail ends, which are away from a connecting plate, of L-shaped long arms of the two floating frames, and the two ends of the soil pressing roller are provided with pin shafts; a U-shaped soil scraping plate is mounted on the L-shaped long arms of the two floating frames through two U-shaped side edges; and a U-shaped opening of the soil scraping plate faces the forwarddirection of the potato harvester. The loss-reducing laying and gathering device of the double-shaking separation potato harvester has good loss-reducing and loss-preventing effects and is accurate and reliable to adjust. The loss-reducing laying and gathering device has the advantages of limiting protection, resistance reduction and obstacle avoidance, the potato exposing rate can be ensured, andthe harvesting quality is improved.

Description

technical field [0001] The invention provides a double shake separation potato harvester damage reduction laying gathering device, which is mainly used for damage reduction and damage prevention in the process of potato mechanized harvesting. Background technique [0002] At present, in the existing potato segmental harvester, the potato-soil mixture is directly dropped on the ground surface after harvesting after completing the separation and soil removal process on the separation sieve. The ground surface after harvesting is relatively higher than the original furrow, so The potato pieces that fell near the edge of the furrow slipped to the furrow, causing crushing damage to the potato pieces due to the running of tractor tires and harvester wheels. If the post-harvest surface can be leveled according to the operating conditions, that is, a compacting device that can realize convenient adjustment and self-adaptive regulation of the post-harvest surface is used, and the sep...

Problems solved by technology

However, field tests have found that the real-time floating compaction effect of the above two technologies is far from enough, and the insufficient floating compaction effect of the soil rollers leads to poor drag reduction and obstacle avoidance capabilities of the compaction device, resulting in partial lateral damage of potatoes. Flow and burial phenomena, affecting the clear potato yield, resulting in unnecessary potato harvest losses
