Disc cutter ratooning rice harvesting header and harvester provided with same

Abstract

The invention provides a disc cutter ratooning rice harvesting header and a harvester provided with the same. The disc cutter ratooning rice harvesting header comprises a disc cutter, a header rack, an ear head cutter and a stubble cutter, wherein the ear head cutter is installed at the front end of the header rack, the disc cutter is installed below the header rack and located below the rear portion of the ear head cutter, and the stubble cutter is used for being hinged to a chassis of the harvester and located below the rear portion of the disc cutter. The disc cutter is used in cooperation with the ear head cutter and the stubble cutter, the grass-grain ratio of materials can be reduced, so that the power consumption of the harvester is reduced, the stubble height highly meets the growth requirement of ratooning rice in the regeneration season, on the basis, the disc cutter is used for cutting stalks between the ear head cutter and the stubble cutter at a time, overlong stalks are prevented from falling into the field, long stalks are prevented from being accumulated on the stubble cutter, guarantee is provided for returning the stalks to the field and smooth working of the stubble cutter, market requirements are met, and wide application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a regenerated rice harvesting header with a disc cutter and a harvester equipped with the header. Background technique [0002] Ragnarok rice is a special rice planting model, which is suitable for areas where the sunlight and heat are not enough to grow double-cropping rice, but there is more than enough single-cropping rice. With many advantages, it is an important measure to improve the multi-cropping index of land and ensure food security in our country, and has great promotion prospects in our country. The harvest period of ratooning rice is divided into two seasons. When the first season of rice is harvested, the rice stumps and root system of the lower third of the plant need to be preserved, and after fertilization and cultivation, let it grow another season of rice. At present, the harvesting of the first season of ratooned rice mainly relies ...

AI Technical Summary

Problems solved by technology

At present, the harvesting of the first season of ratooned rice mainly relies on manual harvesting or the use of existing harvesters. The main problems are: manual harvesting is time-consuming and laborious, while harvesting with existing harvesters is a waste of power, and the rolling rate is as high as 40%-50% %, large damage to rice piles, etc., seriously restricting the popularization and planting of ratooning rice

[0003] For example, the utility model patent CN201820287659.3 discloses a four-wheel-drive low-rolling ratooned rice harvester, which includes high-clearance four-wheel drive chassis, header, conveying parts, threshing parts, granary and other components. And the high ground clearance chassis reduces the rolling rate and reduces the damage of the chassis to the rice piles, but the work efficiency is low; the utility model patent CN201620804158.9 discloses a ratooned rice harvester with variable wheel spacing of the driving wheel, including the chassis, and the front end of the chassis is set There are a pair of front wheels, and a rear wheel is arranged at the rear end of the chassis. The two sides of the bottom of the front end of the chassis are respectively equipped with telescopic mechanisms to control the lateral movement of the front wheels on the corresponding side. The front end of the chassis is also equipped with a Taihe threshing device. The invention Although the avoidance of rice piles is realized by adjusting the driving wheel, it cannot meet various production conditions because it uses ordinary traveling wheels, and the machine does not have a grain box, so the work efficiency is low
