[0002] At present, the headers on the grain combine harvester are all set on the bridge and move with the harvester. Due to structural design defects, the headers of this type of harvester do not have the function of lateral profiling. During operation, due to the The horizontal length is long, and the header can only be harvested in the same plane. When the terrain is inclined, it may result in missed harvesting of grains in the lower terrain

The invention discloses a horizontal profiling device for a cutting table of a grain harvester, which relates to the technical field of agricultural machinery. It includes the frame, the lower end of the frame is fixedly connected with the bridge, the second mounting plate is installed at the front end of the bridge, the upper articulated shaft is fixedly arranged in the middle of the frame, and the cutting platform is provided with profiling wheels at both ends of the cutting platform; The end of the platform away from the harvesting direction is fixedly connected with a first mounting plate; the first mounting plate and the second mounting plate are connected in rotation through an upper articulated shaft. The invention can realize the horizontal profiling of the header along with the ground surface; the load of the profiling process can be reduced due to the bearing effect; the pressure of the header on the profiling wheel is reduced due to the assist of the spring; the damping of the hydraulic cylinder Therefore, the action is soft during the profiling process of the header.
Description
technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a transverse profiling device for a header of a grain harvester. Background technique [0002] At present, the headers on the grain combine harvester are all set on the bridge and move with the harvester. Due to structural design defects, the headers of this type of harvester do not have the function of lateral profiling. During operation, due to the The horizontal length is long, and the header can only be harvested in the same plane. When the terrain is sloped, it may result in missed harvesting of grains in the lower terrain. Contents of the invention [0003] The main purpose of the present invention is to provide a horizontal profiling device for the header of a grain harvester to solve the above-mentioned technical problems. [0004] In order to achieve the above purpose, the present invention provides a horizontal profiling device for a grain harvester he...
