Loss-reduction and loss-prevention elastic control soil-pressing mechanism for potato harvester

Abstract

The invention provides a loss-reduction and loss-prevention elastic control soil-pressing mechanism for a potato harvester. The loss-reduction and loss-prevention elastic control soil-pressing mechanism is characterized by comprising a frame, a floating device, a soil pressing device and a power device, wherein the frame comprises vertical columns, reinforcing rods, vertical plates, transverse rods, connecting rods and lugs I; the floating device comprises supporting arms, a cross rod III, adjusting screw rods, lugs II, spring seat plates and compression springs; one ends of two straight-rod-shaped supporting arms are fixedly arranged at two ends of the cross rod III respectively; two supporting arms are parallel to each other; the soil pressing device comprises mounting plates, a coupler,a soil pressing roller and shields; two mounting plates are fixedly arranged at the positions, close to the lugs II, of the supporting arms of the floating device; a hydraulic motor is mounted at theouter side of one mounting plate with the inner side equipped with five shields; and the power output shaft of the hydraulic motor penetrates through the extending ends of the mounting plates and isconnected with the other end, far away from the soil pressing roller, of the coupler. The loss-reduction and loss-prevention elastic control soil-pressing mechanism provided by the invention has the advantages of loss reduction, loss prevention, good elastic soil-pressing effect, accurate and reliable adjustment, guarantee of a potato exposure rate, and improvement of the harvesting quality.

Description

Technical field [0001] The invention provides a loss reduction and loss prevention elastic control soil pressing mechanism of a potato harvester, which is mainly used for loss reduction and loss prevention in the process of mechanized potato harvesting and increasing the rate of bright potatoes. Background technique [0002] At present, domestic potato harvesting has basically achieved mechanization, and segmented mechanized harvesting still accounts for a large proportion. In the operation process of the existing potato segmented harvester, the potato soil mixture is separated on the separating screen and the soil cleaning and impurity removal process is directly dropped on the ground after harvest. Because the position of the "ditch" is low, that is The ground surface is relatively high compared to the original ridges and furrows. After mechanized operations, although the rows of ridges are excavated, the potato pieces are likely to fall from the end of the separating screen to...

AI Technical Summary

Problems solved by technology

During the operation of the existing potato segmental harvester, the potato-soil mixture falls directly on the surface after harvest after completing the separation and cleaning of soil and impurities on the separation sieve. The ground surface is relatively higher than the original furrow. After mechanized operation, although the furrows are excavated, the potato pieces tend to fall from the end of the separator to the ground and flow sideways to the furrow. Often when potatoes in adjacent rows are harvested, crushing and crushing damage will occur due to the driving of tractor tires and the driving of harvester ground wheels

[0003] At the same time, because the soil after excavation and harvesting is relatively soft, some of the soil through the sieve at the end of the separation sieve will bury the potato pieces, thus affecting the increase in the clear potato rate
