Technical Field

The invention relates to a harvesting and processing machine for agricultural and sideline products, in particular to a mechanical device for separating the skin and the bones of yellow kenaf.

Background

The jute and kenaf is a special fiber resource and has wide application. However, the peeling labor intensity is high, the labor and the time are wasted, and each person can only peel 50-100 kg of the fresh skin every day by manual peeling, so the production development is restricted.

In the middle of the 20 th century and the 50 th century, China starts to develop a power peeler for the jute and red ramie, and in the 80 th century, China develops two types of jute and red ramie peeler, namely a broken-bone type peeler and an integral-bone type peeler, but because the peeling efficiency is not high or the peeling quality is poor, the jute and red ramie peeler cannot be widely popularized and applied in production. In contrast, the bone-breaking type operation is simpler and has higher efficiency, so the bone-breaking type prospect is generally considered to be better, and the bone-setting type is difficult to realize mechanization.

A6 HZB-150 type yellow and red ramie boning and peeling machine (see 1983 of China hemp) adopts a rubber roller leather-drawing method, consists of seven parts such as a frame, a striking roller, a rubber roller, a sliding plate, a conveying belt, a feeding housing and a transmission, peels 150 kg of fresh hemp at one hour, and has the disadvantages of complex operation, low efficiency and disordered hemp leather.

In the 4HB-480 type jute and red ramie peeling machine (see No. 5 or ZL201120011151.9 of 2010 of Chinese agricultural machinery), which is developed by the research institute of hemp of Chinese academy of agricultural sciences in recent years, the production efficiency is high (up to 700 kg/h), but the jute bones are crushed, and the bone content of the fresh peel is high (11.691%) by removing the jute bones, leaves, scraps and the like through rolling separation of large and small press rolls and scraping of a peeling roller.

Therefore, the development of the efficient bone-setting peeling machine is a breakthrough technical progress.

The technical scheme of the invention is a clamping, traction and separation mechanism for a bone-setting type jute and red ramie peeling machine. The clamping, traction and separation mechanism is a key part of the whole machine, is arranged at the lower back of the feeding stalk folding mechanism, and consists of an upper clamping and traction body and a lower clamping and traction body which are mutually coupled, and a front hemp stopping stalk and a rear hemp stopping stalk which are arranged at the left side and the right side of the front end of the clamping and traction body. The upper clamping body and the lower clamping body respectively comprise a clamping frame, a driving wheel, a supporting belt wheel and a clamping belt, the wheel shafts of the upper clamping body and the lower clamping body are installed in a staggered mode by half axle distance, the upper clamping body stretches out backwards, the lower clamping body stretches out forwards, the rear hemp blocking stalk is located on the inner side of the front hemp blocking stalk, the inner end of the hemp blocking stalk is inclined forwards when the hemp blocking stalk is blocked by the front hemp blocking stalk and the rear hemp blocking stalk, the top end of the rear hemp blocking stalk is connected with the front lower corner of the feeding stalk folding support side vertical plate, and the top end of the.

The clamping belt is a double-sided wedge-shaped belt, the section of the clamping belt is W-shaped, the upper half part of a longitudinal middle triangular wedge tooth is of an intermittent structure to form a rectangular sawtooth, a steel wire or contract fiber with strong tensile strength is used as a strength layer, rubber or chloroprene rubber with good elasticity is used as the longitudinal wedge tooth on two sides, an upper clamping belt and a lower clamping belt are coupled in a positive and negative phase mode, the rectangular sawtooth surface of the lower belt is the outer side, the front end of the lower belt bypasses a feeding shaft and is driven by a driving wheel arranged on the feeding shaft, the rectangular tooth surface of the lower belt is the outer side, the front end of the lower belt bypasses the feeding shaft and is driven by a driving wheel arranged on the feeding shaft, the rear shaft end of a clamping frame port extends out to facilitate hemp discharge, the upper belt drives forwards and backwards, a belt wheel is manufactured according to the wedge tooth on the section of the clamping belt.

The invention has the beneficial effects that: the transverse feeding type skin-bone separation is realized, the phenomenon of broken bones on the hemp skin of the broken-bone peeling machine and the damage to the hemp skin are eliminated, the energy consumption is reduced (the mechanical properties that the hemp skin has good toughness and strong tensile strength and the hemp skin and the hemp bone are combined by a cambium and are easy to separate are utilized, the defects that the hemp bone is hard and the broken-bone power consumption is large are avoided), and meanwhile, the utilization of the hemp bone (such as carbon preparation) is facilitated.
