A kind of harvester deflection cross bridge and header deflection type harvester

Abstract

The invention discloses an imitated deflection gap bridge for a harvester. The imitated deflection gas bridge comprises a gas bridge body and a hanging plate, wherein an arc-shaped transition plate which is symmetrical about a vertical center line of a gap bridge opening is arranged at one end of the gap bridge body; a hanging plate opening which is formed corresponding to the gap bridge opening is formed in the hanging plate; a positioning mechanism is fixedly arranged below the hanging plate opening; the hanging plate is in fastened connection with one end, provided with the arc-shaped transition plate, of the gap bridge body through the positioning mechanism; a pressing plate is fixedly arranged at the top of the hanging plate; hydraulic cylinders are symmetrically arranged at two ends of the pressing plate, and are electrically connected with a controller which is fixedly arranged on the surface of the gap bridge body; a sliding mechanism which is symmetrical about a center line of the hanging plate opening is also arranged at the two ends of the hanging plate; and the hydraulic cylinders are in sliding connection with the arc-shaped transition plate through the sliding mechanism. When the imitated deflection gap bridge for the harvester disclosed by the invention is used for harvesting bean type crops and short crops, under the state that the gap bridge body does not move, the hydraulic cylinders are used for driving the sliding mechanism fixed on the hanging plate to slide on the arc-shaped transition plate to realize left-right swing, so that a header fixed on the hanging plate is driven to do driven movement.

Description

technical field [0001] The invention relates to a harvester using a parallel deflection to cross a bridge. Background technique [0002] At present, when the existing harvesters harvest dwarf crops or harvest crops in hilly areas, because of the fixed harvesting angle of the header and the influence of terrain, weather and other interference factors, it is easy to cause uneven harvesting of crops, resulting in waste, and harvesting by the harvester. Due to the rapid wear and tear of the table, the field after harvesting by the harvester needs to be re-harvested manually, which brings a large labor burden to the user. Therefore, a simple structure, easy to use and effective mechanism improvement for the deflection operation of the header has been developed. It has become an urgent problem to be solved in related fields. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention designs a harvester using a parallel deflection to cr...
