Header of corn harvester

Abstract

The invention discloses a header of a corn harvester. The header comprises a header frame, wherein a snapping device used for snapping corncobs is arranged on the header frame and comprises a right spiral snapping roll and a left spiral snapping roll. The right spiral snapping roll and the left spiral snapping roll are arranged on the header frame in parallel with a certain distance. The plane where the axes of the right spiral snapping roll and the left spiral snapping roll are located is parallel with the horizontal surface. The right spiral snapping roll and the left spiral snapping roll can rotate towards opposite directions. A batting device used for batting is arranged on the header frame and comprises two groups of batting chains disposed above the right spiral snapping roll and the left spiral snapping roll. The two groups of batting chains are symmetrically arranged with a certain distance, and a plurality of batting jaws are arranged on the batting chains. Two symmetrical snapping boards are fixedly arranged on the header frame at the positions between the batting device and the snapping device, and the snapping boards are provided with downward bending portions. Batting chain tensioning devices are arranged on the header frame.

Description

technical field [0001] The invention relates to a key part of agricultural machinery, in particular to a corn harvester header. Background technique [0002] The header structure of the traditional corn harvester is as attached figure 1 As shown, including the header frame 1', the header frame 1' is provided with a left-handed ear picking roller 2', a right-hand ear picking roller 3', an ear picking box gear 4', a side reel chain gear box 5' and a middle Reel chain gear box 6'; ear picking box gear 4' has four output ends, two output ends output left-handed ear picking roller 2' and right-hand ear picking roller 3', one output end of ear picking box gear 4' Output to the grain chain box 5', the remaining output end of the picking box gear 4' outputs the middle grain chain box 6'; the left-handed ear picking roller 2' and the right-hand ear picking roller 3' are vertically high One low setting, the left-handed ear-picking roller 2' and the right-handed ear-picking roller 3'...

AI Technical Summary

Problems solved by technology

[0005] The fringing roller adopting the above-mentioned structure has the following problems in use, 1. The structure is complex and the failure rate is high

The number of gearboxes on this type of header is large, the structure of the header frame 1' is cumbersome, the transmission is complicated, it is easy to break down, and the maintenance cost is high.

2. Due to the complex structure, the processing and assembly costs are high

3. Too many gearboxes make it difficult to expand the number of rows, making it difficult to install it on a large multi-row corn harvester

4. The ear is easy to be stuck at the bearing seat of the picking roller

Because the front and rear positions of the bearing seats of the left-handed ear picking roller 2' and the right-hand ear picking roller 3' are the same, and the bearing seats do not move, it is easy to cause the ears to be stuck between the measuring bearing seats

5. The spiral picking rollers are arranged one high and one low, resulting in a complex structure for picking ears
