Stem cutting device for harvesting machine

Abstract

The invention relates to a stem cutting device for a harvesting machine, belonging to the field for the stem cutting device. A left hook (46) and a right hook (47) which are respectively arranged on two sides of a turnover cover (45) which can be sleeved on a turnover cover rotating shaft (44) are respectively matched with a left hook mounting hole and a right hook mounting hole which are arranged on a left hook mounting plate and a right hook mounting plate; a hexagonal sleeve pipe (12) for a delivering tool axis (11), which is sleeved on the delivering tool axis (11), is provided with a blade (7) for the delivering tool axis (11), a grass scraping assembly (10) for the delivering tool axis (11), a cover (39), a positioning block (13) on the right end of the blade (7) for the delivering tool axis, a positioning block (14) on the left end of the blade (7) for the delivering tool axis and a stem triggering-in wheel (15); a hexagonal sleeve pipe (38) for a cutting tool axis is provided with a blade (8) for the cutting tool axis, a grass scraping assembly (9) for the cutting tool axis, the cover (39), a positioning block (36) on the left side of the blade (8) for the cutting tool axis, a positioning block (37) on the right side of the blade (8) for the cutting tool axis, a left grass discharging rolling wheel and a right grass discharging rolling wheel, wherein the left grass discharging rolling wheel and the right grass discharging rolling wheel are welded together; and a left plate welding assembly (3) and a right plate welding assembly (3) are respectively arranged on the left side and the right side. The stem cutting device for the harvesting machine has high efficiency and is convenient for maintenance and installation.

Description

Technical field: [0001] The invention discloses a harvester stalk cutting device, which relates to the field of cutting devices for cutting the stalk after the harvester finishes beating grains. Background technique: [0002] In the past, the harvester directly discarded the stems after the grains were harvested into the field from the cover plate on the harvester. Such a long overall stem is not conducive to the soil to absorb its nutrients. Many small sections are thrown into the soil again, then the small section stems are easily rotted by the soil, and its nutrients are easily absorbed by the soil, so the stem cutting device should be designed for harvesters. Invention content: [0003] The purpose of the present invention is to provide a harvester stalk cutting device, which cuts the stalk into several small sections by the blades on the conveying knife shaft assembly and the grass cutting knife shaft assembly, and throws them into the soil to reach the stalk The rod...

Problems solved by technology

[0002] In the past, the harvester directly discarded the stems after the grains were harvested into the field from the cover plate on the harvester. Such a long overall stem is not conducive to the soil to absorb its nutrients. If many small pieces are thrown into the soil, the small pieces of stems are easily rotted by the soil, and the nutrients are easily absorbed by the soil, so it should be designed for the stem cutting device of the harvester.
