Description
Technical Field
The invention belongs to agricultural machinery, and mainly relates to a flexible driving double-layer cutter bar moving cutter component for cutting and harvesting hemp.
Background
Due to the special character of the hemp, great difficulty is brought to the research and development of special hemp harvester. At present, most of China adopts a modified rice and wheat harvester for harvesting hemp (also called fiber industrial hemp), however, because the hemp is a fiber crop, the growth speed is high, the plant is high, the thickness and the length of the stem are not uniform, the bast fiber is long and flexible, and the hemp bone is brittle and hard, the traditional single-layer cutter bar moving knife part can cut off the hemp stem when cutting the hemp, but the single-layer cutter bar is easy to bend or break, the blade is thin and easy to curl, the reliability is low, and the applicability to thicker hemp stems is particularly poor; the special cutter has poor effect of cutting the bast fiber during operation, irregular and inconsistent cutting, cutter blockage failure and low operation efficiency, and the cutter bar is easy to damage because the driving swing ring box is in rigid driving connection with the cutter.
Disclosure of Invention
Aiming at the problems in the prior art, the invention researches and designs a flexible driving double-layer cutter bar moving cutter component for cutting hemp with a new structure by combining the actual requirements of the current hemp cutting operation, thereby achieving the purposes of strong cutting capability, good cutting quality, high cutting efficiency, small operation vibration, stable operation, high strength and difficult damage.
The flexible driving rod is formed by connecting a connecting ring, a flexible section and an anti-interference convex section of a blade pressing part in sequence, a swinging ring box connecting sleeve is fixedly installed in the connecting ring, a rigid cutter bar, a flexible cutter bar and a cutting blade are fixedly installed on the lower side part of the flexible driving rod from top to bottom in sequence through a riveting structure, and thus the China hemp cutting flexible driving double-layer cutter bar moving blade part is formed.
The flexible driving rod with the flexible section is adopted to drive the cutting blade in a reciprocating manner, and during operation, the flexible section is transmitted through the connecting sleeve and the connecting ring of the swing ring box along with the driving force of the reciprocating movement of the swing ring box, so that the flexible section can counteract the vertical acting force generated by the flexible section, and the flexible driving is realized; the rigid cutter bar and the flexible cutter bar jointly form a double-layer cutter bar, and the double-layer cutter bar has rigidity and internal flexibility; meanwhile, the structural design of the upper inclination angle of the knife body is 2 degrees with the included angle of 56 degrees of the cutting edges at two sides and the cutting front line, so that the cutting blade can realize good sliding cutting effect in the cutting process of hemp stalks, and is particularly suitable for and meets the cutting requirement of hard hemp with tough fibers at the outer part.

Description of part numbers in the figures: 1. the device comprises a flexible driving rod, 2, a cutting blade, 3, a flexible cutter rod, 4, a rigid cutter rod, 5, a swing ring box connecting sleeve, 6, a connecting ring, 7, a flexible section, 8, a blade pressing part anti-interference convex section, 9, a blade pressing part, 10 and a fixed cutter part.
Detailed Description
The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. A flexible driving double-layer cutter bar moving cutter component for hemp cutting is characterized in that a flexible driving rod 1 is formed by sequentially connecting a connecting ring 6, a flexible section 7 and a blade pressing component anti-interference convex section 8, a swinging ring box connecting sleeve 5 is fixedly installed in the connecting ring 6, and a rigid cutter bar 4, a flexible cutter bar 3 and a cutting blade 2 are fixedly installed on the lower side portion of the flexible driving rod 1 from top to bottom in sequence through a riveting structure. The thickness dimension H of the blade body of the cutting blade 2 is 3 mm, the included angle alpha of the cutting edges at the two sides is 56 degrees, and the included angle beta between the cutting sharp line of the cutting edge and the vertical direction of the blade body is 2 degrees.
When the cutting device is used, the hemp cutting flexible drive double-layer cutter bar moving cutter component assembly is arranged on the fixed cutter component 10 in a clearance fit manner through the pressing blade component 9, and is connected with a swing ring box with power input on a harvester by utilizing the swing ring box connecting sleeve 5 and the connecting ring 6. During operation, the input power of the pendulum ring box pulls the flexible driving rod 1 to and fro through the pendulum ring box connecting sleeve 5 and the connecting ring 6 and drives the rigid cutter bar 4, the flexible cutter bar 3 and the cutting blade 2 to do linear reciprocating motion, and under the cooperation of the fixed cutter component 10, the cutting blade 2 finishes the cutting operation of the hemp stalks.
