Gantry type rape brassica campestris harvester

Abstract

The invention discloses a gantry type rape brassica campestris harvester. The harvester comprises a gantry type crawler walking chassis, a cutting device and a conveying and collecting device; and the cutting device comprises a header frame, dividers installed on the two sides of the bottom of the front face of the header frame, a pair of middle sliding rails installed on a truss in the middle of the header frame, a plurality of vertical header devices evenly installed on the middle sliding rails at intervals, a fixed cutter arranged on a beam at the bottom of the rear face of the header frame and a header motor installed on the header frame. The row-aligned harvesting operation of rape brassica campestris is completed by utilizing the vertical header devices, the rape brassica campestris is supported and guided to the conveying and collecting device by utilizing seedling pulling rollers arranged on the vertical header devices, and the conveying and collecting operation of the rape brassica campestris is completed by utilizing the conveying and collecting device. The vertical header devices which operate independently achieve row-to-row harvesting of the rape brassica campestris, and meanwhile the distance between the vertical header devices is adjustable, so that the adaptability of the harvester to harvesting of the rape brassica campestris with different row distances and breadths is effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a gantry type rapeseed harvester. Background technique [0002] Rapeseed is the main oil crop in my country. In 2019, the planting area was 6,583.09 thousand hectares, and the rapeseed output was 13.4847 million tons. Its oil production accounted for more than 50% of the total oil production of oil crops in my country. In recent years, the price of rapeseed has declined, and the income from planting rapeseed has decreased. Studies have shown that proper pruning of rapeseed can increase income by 600 yuan per mu, which is an effective way to increase the benefits of rapeseed planting. [0003] The picking of rapeseed is labor-intensive and low-efficiency. In order to save money and increase income for farmers, mechanized harvesting of rapeseed is an inevitable trend in the development of the situation. It is also of great significance to promote the opt...

[0003] The picking of rapeseed is labor-intensive and low-efficiency. In order to save money and increase income for farmers, mechanized harvesting of rapeseed is an inevitable trend in the development of the situation. It is also of great significance to promote the optimization of labor production structure and ensure the quality and yield of rapeseed.

When the rapeseed is harvested, only a small part of the top of the rapeseed is harvested. As the rapeseed grows, its harvest height and width change continuously. Mechanized harvesting is difficult, and the existing vegetable harvesters are difficult to adapt to its characteristics.
