Problems solved by technology

[0003] According to the applicant's understanding, most of the potato combined harvesting used in developed countries currently adopts thin rod-type elevating separators, which use two layers of rod conveyor chains in parallel, with seedlings on the upper layer and potatoes on the lower layer, using the difference in operating speed between the two layers of ch

Embodiment 1

[0020] The grooved roller type potato tuber separation and residual seedling removal mechanism of the present embodiment is as follows: figure 1 and figure 2 As shown, the conveying rod lifting chain 9 is surrounded on the excavating conveying device 1 at the front end of the potato combine harvester, and the high end of the conveying rod lifting chain 9 is equipped with a rod pressing roller 5 driven by a power device. Bar top pressure roller 5 such as image 3 As shown, when the outer circumference is uniformly distributed, it is positioned at the pressing roller bars 8 between the interval distribution lifting chain bars.

[0021] The top of the bar pressing roller 5 is equipped with an elastic bar mechanism 12 mainly composed of an elastic curved bar 10 and an elastic bar compression spring 11. The upper end of the elastic curved bar 10 is hinged on the frame, and the lower end Extending from the elastic bar mechanism, it is an arc section matching the outer circle of t...

Abstract

The invention relates to a grooved roller type separating and broken seedling removing mechanism of potato tubers and belongs to the mechanical field of agricultural harvesting machines. The mechanism comprises a conveying bar elevator chain (9) of a surrounding excavation conveying device (1). A bar pressing roller (5) driven by a power device is arranged on a high end of the conveying bar elevator chain (9). An elastic bar mechanism (12) is arranged on the bar pressing roller and extends out of an elastic bent bar (10) which is pressed on the output end of the conveying bar elevator chain. A groove type seedling removing roller (4) engaged to the bar pressing roller is installed under the bar pressing roller via axially-extending grooves uniformly distributed in the outer periphery. The mechanism is capable of allowing seedlings entering thereof to be in concave and convex compression sate, so frictional drawing force is remarkably increased and it is improbable for the seedlings to struggle against the mechanism but being drawn off from potatoes, so seedling removing rate is remarkably increased.

Description

technical field [0001] The invention relates to a tuber separating and removing residual seedling mechanism for a potato combine harvester, in particular to a grooved roller type potato tuber separating and removing residual seedling mechanism, which belongs to the technical field of agricultural harvesting machinery. Background technique [0002] Potato crops such as sweet potatoes and potatoes have the characteristics of planting on high ridges, lush seedlings, thin root tubers and tender flesh. Among them, sweet potato is a creeping plant, and its seedling stem usually grows to 1.5 to 7.0 meters, which can cover the entire ridge and the ground, intertwined and difficult to separate; potato seedlings are upright, and the height is generally more than 0.5 meters. Therefore, before harvesting, the seedling stems are usually crushed and returned to the field with the seedling stem crushing machine, and the crushed broken seedling stems are directly spread on the ridge surface...
