Harvester stalk-poking mechanism for high-stalk crops

Abstract

The invention discloses a harvester stalk-poking mechanism for high-stalk crops. The harvester stalk-poking mechanism comprises two poking cylinder devices, and the two poking cylinder devices are positioned at the two sides of a harvester vehicle in the width direction of the harvester vehicle respectively; each poking cylinder device comprises a fixing shaft, a guidance sleeve, poking figures and a drive component, and the guidance sleeve is provided with a sliding hole; the axis of the fixing shaft and the axis of the guidance sleeve are parallel to each other and eccentric, and one end of the fixing shaft is fixedly connected to the harvester vehicle while the other end of the fixing shaft is movably connected with the guidance sleeve through a crank mounted on the end of the fixing shaft; one end of the crank is fixedly connected with the fixing shaft while the other end of the crank is movably connected to the center axis of the guidance sleeve; when the drive component drives the guidance sleeve to move along the center axis of the guidance sleeve, the poking figures movably connected to the fixing shaft can axially slide in the slide hole; when pushing the high-stalk crops to a conveyor chain, the stalk-poking mechanism can effectively avoid direct transferring the high-stalk crops to the conveyor chain, and have a good effect on harvests of the high-stalk crops.

Description

technical field [0001] The invention relates to the technical field of agricultural harvesting machinery, more specifically, it relates to a stalk pulling mechanism of a high-stalk crop harvester. Background technique [0002] The harvester is one of the commonly used agricultural machinery, and the reel device is a common part on the harvester. At present, harvesters for crops with short and thin stalks (such as rice, wheat, and forage grass, etc.) are all equipped with a lower reel device, which plays a role in supporting and harvesting lodging crops. Corn, sorghum, etc.) are poorly supported by the lower reel alone, and the stalks are prone to lodging forward, which affects the harvesting efficiency of the harvester. [0003] At present, the Chinese patent with the notification number CN202799669U discloses a high-stalk crop harvester, which includes a motor vehicle body, a horizontal main cutter arranged on the front side of the motor vehicle body, and two augers arrang...

Problems solved by technology

Although this kind of harvester can push the crops that are falling forward into the auger backward by the first lever, and then transport the crops backward through the spiral rotation and lifting function of the auger, the dial is directly installed on the harvester. During the rotation of the dial, the lever will drive the high-stalk crops directly to the conveyor chain, which will easily interrupt the high-stalk crops, reduce its use value, and even cause damage to the lever or the conveyor chain, reducing its service life
