Self-adaptive header of a leaf vegetable combine harvester

Abstract

The invention relates to an adaptive cutting platform of a leafy vegetable combine harvester, which belongs to the technical field of agricultural machinery. The header includes a leaf clip lifting conveying mechanism whose rear end is hinged on the frame column, and a root cutting mechanism and a leaf cutting mechanism at the front and rear ends; the leaf clip lifting conveying mechanism includes a loop conveyor belt clamped inside; root cutting The mechanism includes optical disc knives and serrated disc knives in a V-shaped overlapping distribution; the vertical transmission shafts of the optical disc knives and serrated disc knives are respectively supported on the transmission shaft mounting seats fixed on the corresponding wheel frames, and the vertical transmission shafts of the transmission shafts The upper end is transmission-connected with the power transmission mechanism at the front end of the front outrigger through a universal transmission mechanism containing two-stage universal joints. The invention properly solves the problems of root cutting and conveying of cabbage head harvesting, can realize accurate root cutting and non-destructive conveying, thereby creating conditions for ensuring the harvest quality of mechanical harvesting.

Description

technical field [0001] The invention relates to a soil-surface-headed vegetable harvester header with stems and leaves, in particular to a combined harvester self-adaptive header capable of harvesting various stems, leaves and bulbous vegetables, belonging to the technical field of agricultural machinery . Background technique [0002] The scientific name of green cabbage head is stem tumor mustard, which is the main raw material for making Fuling mustard. For a long time, the harvest of green cabbage has been dominated by manual harvesting, which has high labor intensity and low work efficiency, which has seriously affected the yield, quality and economic benefits of pickled mustard. The unique growth characteristics of cabbage head is the reason why its mechanized harvesting is difficult. First of all, the fibrous roots of the cabbage head are well developed, but the stems and leaves are fragile and easy to break, so there are many problems in harvesting by cutting the r...

Problems solved by technology

[0005] The above-mentioned prior art fails to properly solve the root-cutting and conveying problems when the head of cabbage is harvested

Moreover, no matter whether the overall height of the header is adjusted by the suspension adjustment mechanism or the height adjustment rod, for multi-row (2 rows and above) harvesting, when the root cutting height of the cabbage heads in each row is inconsistent, the independent adjustment of the height of each row cannot be realized. Cutting height, it is difficult to ensure the quality of root cutting
