Whole-stalk hemp fiber peeling device

Abstract

The invention discloses a whole-stalk hemp fiber peeling device, and belongs to the technical field of agricultural machinery. The whole-stalk hemp fiber peeling device comprises a frame, a power device, a transmission mechanism, a feeding and stalk breaking mechanism, a traction separation mechanism and a fiber extracting mechanism. The feeding and stalk breaking mechanism is arranged right abovethe front of the whole device and comprises a front hemp feeding disk shaft, a rear hemp feeding disk shaft and a stalk breaker, the front hemp feeding disk shaft and the rear hemp feeding disk are the same in diameter and rotation speed and opposite in turning directions, and hemp feeding ports correspond to each other. The traction separation mechanism is arranged at the lower back of the broken stalk feeding mechanism, is longitudinally symmetric and comprises a front-back turning traction unit, a backward traction unit and a hemp stopper, the rotation speed of a traction chain-gear is twice that of a hemp feeding disk, the turning direction of the traction chain-gear is opposite to that of the hemp feeding disk, the number of ratchets of a chain encircling the chain-gear is half of that of the hemp feeding ports, working edges of the ratchets on axial planes of the hemp feeding disk and the chain-gear are flush with those of the hemp feeding ports, and the fiber extracting mechanism comprises a horizontal fiber extractor and a vertical fiber extractor. The whole-stalk hemp fiber peeling device is applicable to whole-stalk harvesting and processing of ramie, jute and kenaf, canbe individually fixedly operated on a site, realizes centralized processing, can also be matched with a fiber extractor and movably operated in the field, and realizes combined harvesting.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to the harvesting and processing of agricultural by-products, in particular to a mechanical device for primary processing of jute, kenaf and ramie fibers. Background technique [0002] Yellow, red, and ramie are all main economic crops in my country, and hemp fiber has been an important textile raw material in my country since ancient times, and enjoys a high reputation in the world. The development of yellow, red and ramie is of great significance for military supplies and civilian use, export trade, economic development of hemp areas and increase of farmers' income. However, harvesting and stripping are labor-intensive, require high technology, are highly seasonal, and consume a lot of labor. The manual peeling of yellow and kenaf can only peel 50-100 kg of fresh skin per person per day, and the manual peeling of ramie per person per day Only 2-5 kilograms of raw hemp...

Problems solved by technology

[0004] However, due to various reasons, such as hemp is a small crop, the planting scale is small, it has not attracted enough attention, and the investment in research and development is seriously insufficient; Numbness, the particularity of the crop itself, the incompatibility of agricultural machinery and agronomy, etc., it is difficult to tackle key problems, the mechanized production and processing technology is relatively backward, the technical level is not high, and some are still very immature, or even blank, and have not fundamentally solved the problem of harvesting. Difficult to process

The working principle of the existing power machinery equipment is that the high-speed rotating blade roller breaks and squeezes the hemp stalks to separate them, which has the following defects: 1. Fiber damage, black color, entrained bone fragments, and poor quality; 2. Longitudinal feeding, intermittent work, can not be matched with the hemp cutting machine, realize joint harvesting, low work efficiency; 3, breaking the hemp bone, power consumption is large, and unfavorable for the use of hemp bone
