Gap adaptive vertical snapping roll device

Abstract

The invention belongs to the field of agricultural machinery, and especially relates to a gap adaptive vertical snapping roll device. The gap adaptive vertical snapping roll device comprises a mounting frame and two groups of clamping devices arranged on the mounting frame, wherein the two groups of clamping devices rotate in opposite directions; each clamping device comprises a fixed roller device, an adjustment roller device and an adjustment component; one end of the fixed roller device is rotatably arranged on the mounting frame, and the other end thereof is movably connected with the adjustment roller device; the other end of the adjustment roller device is connected with the adjustment component; and the adjustment component is fixed on the mounting frame. According to different thicknesses of corn stalks in the field, the reactive force of the stalks to a snapping roll acts on the adjustment component, so that the adaptive process of the corn stalks in a snapping roll gap can berealized. The congestion problem caused by the retention of the corn stalks because the pressing force between the corn stalks and the snapping roll is too small during the ear-snapping process can be effectively avoided, and a corn stalk snap phenomenon occurring in the ear-snapping process because the pressing force between the corn stalks and the snapping roll is too large is also avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a gap self-adaptive vertical ear picking roller device. Background technique [0002] At present, the ear picking principle of the vertical corn ear harvesting platform is as follows: the corn stalks are fed obliquely with the stalk rollers, and then pass upwards and backwards through the gap between the two ear picking rollers as the two ear picking rollers continue to rotate. gap. The overall shape of the corn plant shows a trend from thick to thin from the root to the top of the plant. Therefore, in order for the corn plant to pass through the gap between the two ear rollers smoothly, the two ear rollers must be aligned. There is sufficient compaction throughout the corn stalk. [0003] Corn plants in the field vary in their growth conditions, and their stalks vary in thickness. At present, the ear picking roller device commonly used in the existing vertical ...

Problems solved by technology

At present, the ear picking roller device commonly used in the existing vertical corn harvesting headers in my country cannot realize the self-adaptive process of corn stalks, so the passing performance of corn stalks during the ear picking process is too poor, resulting in congestion of vertical headers The phenomenon is common and affects the progress of corn harvest

[0004] When the traditional gap-adjustable vertical ear-picking roller device is working in the field, when the stalks of individual corn plants are significantly thinner than those of other plants, it is easy for the ear-picking roller group to fail to clamp and pass through the ear-picking gap. , resulting in the congestion of the header; and when the stalks of individual corn plants are significantly thicker than those of other plants, it is easy to cause the stalks to be broken due to too small clamping gaps. When the broken stalks stay in the When the corn is harvested on the header, it is also easy to cause congestion on the header
