Loss reduction laying and compacting device of potato and onion harvester

Abstract

The invention provides a loss reduction laying and compacting device of a potato and onion harvester. The loss reduction laying and compacting device includes a machine frame, a floating device and asoil pressing walking device. The frame machine includes a stand column, a reinforcing rod, a vertical plate, a cross rod, a connecting rod and a lug. The loss reduction laying and compacting device is characterized in that the floating device includes a supporting arm, a floating arm, an adjusting screw sleeve, an adjusting lead screw and a compression spring, the two U-shaped sides of the supporting arm of a U-shaped structure extend toward a same direction perpendicular to a U-shaped plane, lugs III are arranged at the extended U-shaped sides of the supporting arm, and circular holes with equal diameter and coaxial axis are formed in the lugs III. The soil pressing walking device includes a soil pressing roller, right-angle frames, a soil scraping plate and a ground wheel. The soil pressing roller is supported in a round hole in the end, arm away from a lug V, of the floating arm through pins at the two ends, and the two right-angle frames with right-angle cross-sections are installed on the lower surface of the end, equipped with the soil pressing roller, of the floating arm through a right-angle side plate. The effects of reducing damage and preventing damage are good, the dead weight of the machine can be used to compact the ground surface, the covering rate of potatoes and onions is reduced, and the harvest quality is improved.

Description

technical field [0001] The invention provides a potato and onion harvester damage reduction and laying compaction device, which is mainly used for damage reduction and damage prevention in the mechanized harvesting process of potatoes and onions. Background technique [0002] Potatoes and onions are generally grown using ridge farming. At present, the existing potato and onion segmented harvesters, potato-soil mixture and onion-soil mixture directly drop on the ground surface after harvesting after completing the separation and soil cleaning and impurity removal process on the separation screen. The position of the original furrow was relatively high, so the potato cubes that fell near the edge of the furrow slipped to the furrow, causing crushing damage to the potato cubes and onions due to the running of the tractor tires and the ground wheels of the harvester. At the same time, the scattered soil without compaction will also affect the clear potato rate, or cause the phe...

Problems solved by technology

However, field tests have found that the above two technologies rely only on the weight of the soil roller to compact the harvested ground surface is far from enough, and the insufficient force exerted by the soil roller on the ground surface leads to poor soil compaction effect, resulting in potatoes and Partial side flow and burial of onions, resulting in unnecessary harvest losses
