Description

Mulberry leaf collector

Technical Field

The utility model relates to a pick the field, especially relate to a mulberry leaf collector.

Background

At present, the demand of mulberry leaves is increasing in China with the vigorous development of the modern pharmaceutical industry and textile industry. The mulberry leaves are used as traditional Chinese medicinal materials in the pharmaceutical industry and are one of raw materials of a plurality of medicines; in the textile industry, it also plays a vital role as an important food source for silkworms. The mulberry leaf picking is the most arduous link in the mulberry leaf industry. The mulberry tree planting method has a long history and a wide planting region of mulberry tree planting, but the working mode of manually picking mulberry leaves is followed for hundreds of years, the efficiency is low, the damage to hands is large, fingers of mulberry farmers are deformed, bone joints are thick due to long-term picking of the mulberry leaves, and tenosynovitis becomes an occupational disease of the mulberry farmers.

The liberation of hands is the key to the success of the mulberry leaf collector. At present, the mulberry leaf collector in the market of China realizes partial mechanization, reduces the damage to human bodies in the picking process, but still needs the whole participation of human hands, has low degree of mechanization and still has large labor intensity of the human bodies; the mulberry leaves collected at one time are few, the picking efficiency is low, and the efficiency advantage of machinery relative to people cannot be well exerted; the general collector is single and fixed in shape, is difficult to collect the mulberry with low planting standardization degree and is not beneficial to pushing and collecting by people; and the cutter is easy to damage the branches in the working process, thereby causing unnecessary economic loss. Such devices are time consuming and labor intensive, which greatly limits the development of the mulberry leaf industry.

In recent years, partial mechanized small-sized equipment enters the market, the efficiency is improved to a certain extent compared with a manual picking mode, the workload of mulberry farmers is reduced, the manual whole-course control is still needed, the mechanization degree is not high, the labor cost is still high, and the efficiency is further improved.

The prior multi-degree-of-freedom electric mulberry leaf picking machine has the technical scheme as follows: the cutting tool comprises a travelling mechanism, a transmission mechanism, a supporting mechanism and a cutting tool, wherein the travelling mechanism comprises a bottom supporting frame and 4 supporting rollers, the transmission mechanism comprises an eccentric wheel, a sliding block and a fixed sliding chute, the supporting mechanism comprises two multi-degree-of-freedom supporting rod sets, and the cutting tool comprises an upper blade, a lower blade, an adjusting screw and a supporting frame; the action principle is that when the eccentric wheel rotates, the distance from the surface of the eccentric wheel to the rotating center is different, so that the sliding block is pushed to rapidly move back and forth in the fixed sliding groove, and the shearing action of the cutter is guaranteed. Compared with manual picking, the picking machine has great progress, can reduce the labor intensity of mulberry farmers and improve the picking speed of mulberry leaves, but still brings great labor cost to the mulberry farmers because the mulberry leaves are manually held and operated in the whole process; the cutter is single, and the picking speed is not improved qualitatively; the fixed structure has weak adaptability to the mulberry and cannot be generally used for the mulberry with uneven growth status. The picking machine does not exert the mechanical advantage over the manual one well.
