Cyperus esculentus harvester

Abstract

The invention provides a Cyperus esculentus harvester. The Cyperus esculentus harvester comprises a frame, walking wheels, a Cyperus esculentus temporary storage hopper, a power mechanism, a transmission mechanism, a soil-turning rotary-tillage roll, a shovel plate located behind the rotary-tillage roll, a lifting conveyor belt connected with the shovel plate, a double-layer cylindrical sieve-drumroller sieve connected with the lifting conveyor belt, a spiral blade propeller arranged in an inner sieve drum, an axial pushing plate arranged in an outer sieve drum, a circular arc Cyperus esculentus grain receiving groove arranged at the outer end of the outer sieve drum, a stirring sheet extending into the receiving groove from the outlet end of the inner sieve drum, and a conveyor connecting the receiving groove with the Cyperus esculentus temporary storage hopper, wherein the sieve pore of the inner sieve drum is larger than a Cyperus esculentus grain; the sieve pore of the outer sievedrum is smaller than a Cyperus esculentus grain; sieve drums are supported by a roller and driven by a gear ring and a power gear arranged on the outer circumference of the sieve drums. The Cyperus esculentus harvester provided by the invention has the following positive effects: mechanized harvesting of the Cyperus esculentus with grains dispersed and born in soil is realized; and compared withconventional artificial harvesting, the Cyperus esculentus harvester has the following advantages: few Cyperus esculentus grains are remained in the the soil; labor intensity is greatly reduced; production efficiency is tens times higher than the production efficiency of artificial harvesting; and the Cyperus esculentus harvested by the Cyperus esculentus harvester is clean and has few impurities.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a crop harvester for underground grain and fruit. Background technique [0002] Yassa bean is a high-quality oil crop introduced from Africa in recent years. Its seeds are rooted underground, with a particle size of 1-2cm. The surface is uneven and has roots. Due to the small size and large number of fruit seeds, and it is difficult to pull out the seedlings, usually the above-ground seedlings are harvested as high-quality forage grass, and then the soil is turned to harvest the seeds. Since this crop has just been introduced and is introduced from an area with backward mechanical technology, there is no corresponding harvesting machine at present, and it is basically harvested manually, with high labor intensity, low recovery rate and high production cost. Contents of the invention [0003] The object of the present invention is to provide a harvester for t...
