Differential type separation platform

Abstract

The invention provides a differential type separating platform which comprises a stand; a flexible drum and a rigid drum which are mutually parallel and are connected with a driving device through a transmission device can be rotationally fixed and supported on the stand, and a clearance is arranged between the flexible drum and the rigid drum; the transmission device enables the flexible drum and the rigid drum to oppositely rotate, and the rotational speed of the flexible drum is less than that of the rigid drum; or the transmission device adopts the matching relationship with the outside diameters of the flexible drum and the rigid drum, i.e., the linear speed on the outer circumference of the flexible drum is less than that of the rigid drum; a soft material layer is fixedly arranged on the rigid drum wall of the flexible drum, and the drum wall of the rigid drum is made of rigid material; and a plurality of grooves are arranged on the rigid drum along the axial direction in a penetration way, and the grooves are circumferentially distributed in parallel around the drum wall. The differential type separating platform can effectively separate poppy shells and stems, cannot enable the poppy shells to be extruded into powder due to excessive extrusion, is favorable for the cleaning of the poppy stems, the shells and the seeds in the later period, and also provides a foundation for the manufacturing and the development of the poppy combine harvester.

Description

technical field [0001] The invention relates to a differential speed separation platform for special crops, belonging to the technical field of special machinery. Background technique [0002] Poppy is a special crop, which can be divided into three categories: ornamental poppy, medicinal poppy, and wild poppy according to its use. The medicinal opium poppy is one of the important medicinal plants. At present, all countries use the cultivation of opium poppy as the main source of narcotics and analgesic drugs. In Australia, the United States and other countries, opium poppy planting and harvesting have basically been mechanized, ensuring the safety of opium poppy production. However, due to the limitation of machinery and equipment in my country, a large amount of manpower can only be hired to manually pick poppy shells during the harvest season. With the increase of labor costs, the production costs also increase year by year, and more importantly, production safety canno...

AI Technical Summary

Problems solved by technology

In addition, the agronomic form, physical and mechanical characteristics of poppy are very different from those of traditional grains. Therefore, using the threshing separation device of the current grain combine harvester and the modified separation device, it has been proved by practice that the stalks and shells are very broken. The purpose of separating the stalk and shell of poppy cannot be achieved
