Secondary-cutting floating pick device of self-propelled corn harvester

Abstract

The invention relates to a secondary-cutting floating pick device of a self-propelled corn harvester, which aims to automatically adjust the space between two picking rollers and prevent the blockage at the picking rollers of a secondary-cutting opening. The secondary-cutting floating pick device comprises a fixed picking roller device, a movable picking roller device, a transmission shaft device and a lifter shell, wherein the fixed picking roller device comprises a fixed shaft, a fixed picking roller, fixed shaft bearings and a fixed shaft bearing pedestal; and the movable picking roller device comprises a movable shaft, a movable picking roller, movable shaft bearings, a movable shaft bearing pedestal, a right movable shaft rotating arm, a right movable shaft rotating arm, a hanger, asleeve, a washer, a spring and an adjusting nut. The two ends of a round steel sleeve of the fixed picking roller are provided with the fixed shaft bearings, and the two ends of a round steel sleeve of the movable picking roller are provided with the movable shaft bearings; and the fixed shaft and the movable shaft are respectively arranged in the fixed shaft bearings and the movable shaft bearings in a penetrating way, the fixed shaft bearings and the movable shaft bearings are respectively arranged on the fixed shaft bearing pedestal and the movable shaft bearing pedestal, and the fixed shaft bearing pedestal is arranged on the lifter shell.

Description

technical field [0001] The invention relates to a secondary chopping floating pick-up device of a self-propelled corn combine harvester. technical background [0002] When the ears and broken stalks on the header of the existing self-propelled corn combine harvester enter the ear box or peeler from the elevator, the ears and broken stalks will be separated at the exit of the elevator. After falling, the broken stalks will continue to be transported to the secondary pick-up roller at the rear end of the elevator, and picked up by the pick-up roller so that the secondary shredding device at the back can be chopped. Generally, the existing secondary pick-up device is composed of two sets of pick-up rollers with non-adjustable gaps. When the amount of corn stalks entering the pick-up device increases, the load will increase. When it reaches a certain level, the pick-up device will be blocked and the transmission chain will pull. break, and even the elevator will be distorted an...
