Electrically-driven double-acting vertical cutter system for oilseed rape combined harvester

Abstract

The invention discloses an electrically-driven double-acting vertical cutter system for an oilseed rape combined harvester. The electrically-driven double-acting vertical cutter system comprises a motor, an eccentric wheel, a limiting block and an eccentric shaft. A first gear is connected to the end of the motor and the motor is fixedly mounted on the box body. The box body is arranged at the outside the first gear. A second gear is installed inside the box body; and the eccentric wheel is fixed at the side of the second gear. The eccentric shaft is installed at the center of the second gear;a crank is connected with the outer side of the eccentric wheel; and a cutter base is installed at the bottom of the crank. The limiting block is fixed at the bottom of the box body. An upper blade and a lower blade are installed on the cutter base. The system has characteristics of fast cutting speed and small vibration. The blank area for oilseed rape harvesting is reduced; and the inertial force of the blade moving direction can be cancelled effectively. Moreover, the structure is simple; and the complex mechanical structure and hydraulic lines are avoided.

Description

technical field [0001] The invention relates to the technical field of rapeseed harvesters, in particular to an electrically driven double-action vertical cutting knife system for a rapeseed combine harvester. Background technique [0002] When the rapeseed combine harvester harvests rapeseed, it mainly divides the grain at the branch part, and cuts off the entangled rapeseed branches with the vertical vertical cutting knife on the side. The traditional rapeseed header vertical cutter cutter is generally mechanically driven, and adopts a single-moving knife cutting form with a moving blade and a fixed blade. The vertical cutting knife cutter of the traditional rape header has a cutting blank area, which pulls the rape branches and increases the loss, and the vibration generated by the harvester is relatively large, causing the deformation and damage of the cutter parts themselves and the header frame. Reduced machine life and harvest quality. In view of the above problems,...

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of rapeseed combine harvester electric drive double-action type vertical cutting knife system, to solve the above-mentioned background technology, it is mostly a single-action knife type cutter, there is a cutting blank area, pulling the rapeseed branches, increasing the loss, and The vibration generated during the operation of the harvester is relatively large, causing deformation and destruction of the cutter parts themselves and the header frame, which reduces the life of the machine and the quality of the harvest
