China-hemp cutting flexible driving double-layer cutter bar moving cutter component

Abstract

The invention discloses a China-hemp cutting flexible driving double-layer cutter bar moving cutter component, and belongs to agricultural machinery. A flexible driving rod is composed of a connectingring, a flexible section and a blade pressing part anti-interference protruding section; a swing ring box connecting sleeve is fixedly installed in the connecting ring; a rigid cutter bar, a flexiblecutter bar and a cutting blade are sequentially and fixedly installed on the lower side of the flexible driving rod from top to bottom through a riveting structure; and the thickness of a cutter bodyof the cutting blade is 3 mm, the included angle of cutting edges on the two sides is 56 degrees, and the angle between the cutting lines of the cutting edges and the vertical direction of the cutterbody is 2 degrees. The component is novel, reasonable and simple in structure, stable in operation, small in vibration, low in cutting power consumption, good in cutting quality and effect, reliablein use, not prone to damage, high in operation efficiency, low in cost and particularly suitable for and meets the cutting requirement of hard China hemp with tough fibers on the outer portion.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a flexible-driven double-layer knife bar moving knife part for cutting and harvesting hemp. Background technique [0002] Due to the special properties of hemp, it has brought great difficulties to the research and development of special hemp harvesting machines. At present, in China, most of the modified rice and wheat harvesting machines are used for the harvesting of hemp (also known as fiber industrial hemp). The leather fiber is long and flexible, and the hemp bone is brittle and hard in texture. Although the current single-layer knife rod moving knife part can cut the hemp stem when cutting Hanlin, the single-layer knife rod is very easy to bend or broken, and the blade is thin, easy to roll, low reliability, especially poor applicability to hemp stalks; there is also a special cutter, the bast fiber cutting effect is poor during operation, and the stubble often occurs irregu...

Problems solved by technology

At present, in China, most of the modified rice and wheat harvesting machines are used for the harvesting of hemp (also known as fiber industrial hemp). The leather fiber is long and flexible, and the hemp bone is brittle and hard in texture. Although the current single-layer knife rod moving knife part can cut the hemp stem when cutting Hanlin, the single-layer knife rod is very easy to bend or broken, and the blade is thin, easy to roll, low reliability, especially poor applicability to hemp stalks; there is also a special cutter, the bast fiber cutting effect is poor during operation, and the stubble often occurs irregularly and inconsistently. There is also a knife blocking fault, and the work efficiency is low. At the same time, because the drive pendulum ring box and the cutter are rigidly driven, the knife rod is easily damaged.
