Floating header and a combine harvester comprising the same

Abstract

The invention provides a floating header and a combined harvester with the same. The floating header comprises a slide plate group, a plate spring group and a fine adjustment floating mechanism. The slide plate group is positioned at the bottom of a header, and the fine adjustment floating mechanism comprises a cutter floating assembly; the fine adjustment floating mechanism comprises tension springs, a guide rod and roller trains; the slide plate group comprises a plurality of large and small slide plates; one end of each plate spring is fixed onto the corresponding slide plate, and the other end of each plate spring backwardly and downwardly extends to be hinged onto a rear main frame of the header by a hinge pin; one end of each tension spring is fixed to the end, which is close to a cutter, of the corresponding plate spring, and the other end of each tension spring is hung on a front lower main frame of the header by the aid of a long bolt; one end of the guide rod is hinged onto the plate springs, the upper portion of the guide rod is limited in the certain roller train, and the guide rod can slide up and down under the effect of the certain roller train; the roller trains are fixed onto frames on the side walls of the header. The floating header and the combined harvester have the advantages that the productivity can be effectively improved when grains are harvested by the combined harvester, and the grain harvest loss can be reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a floating header for grain harvesting and a combine harvester containing the floating header. Background technique [0002] A few days ago, with the continuous improvement of the level of science and technology, harvesting of grains no longer requires manual harvesting, but harvesting with harvesters. The current harvesters include headers and harvester frames for cutting grains. The header and the frame of the harvester are connected by a feeding chute. Because the current header cannot float up and down freely, when harvesting grains such as soybeans, the distance between the pods of soybeans and the ground is relatively small. When the rigid header harvests soybeans, if the header is too high, many pods will not be able to be cut off, that is, the phenomenon of "cat ear stubble" will appear. Therefore, it is necessary to improve the current grain harvester hea...

[0002] A few days ago, with the continuous improvement of the level of science and technology, harvesting of grains no longer requires manual harvesting, but harvesting with harvesters. The current harvesters include headers and harvester frames for cutting grains. The header and the frame of the harvester are connected by a feeding chute. Because the current header cannot float up and down freely, when harvesting grains such as soybeans, the distance between the pods of soybeans and the ground is relatively small. When the rigid header harvests soybeans, if the header is too high, many pods will not be able to be cut off, that is, the phenomenon of "cat ear stubble" will appear; Therefore, it is necessary to improve the current grain harvester head to harvest grain more effectively
