Multi-stage soil-breaking rhizoma chuanxiong digger

Abstract

The invention relates to the field of agricultural machinery, and provides a multi-stage soil-breaking rhizoma chuanxiong digger which comprises a rack, and a digging shovel, a throwing, soil breaking, separating and conveying component, a tooth type soil breaking, separating and conveying component and a cleaning component are sequentially arranged on the rack from left to right; the throwing, soil breaking, separating and conveying component comprises a soil shaking sieve, and breaking nails for breaking soil are arranged on the soil shaking sieve; the tooth type soil breaking, separating and conveying component comprises a conveying chain belt, and separating teeth are arranged on the conveying chain belt; the cleaning component comprises a soil cleaning plate rotationally connected with the rack and a baffle arranged above the soil cleaning plate; and one end of the soil shaking sieve is located below the digging shovel, one end of the conveying chain belt is located below the other end of the soil shaking sieve, and one end of the soil cleaning plate is located below the other end of the conveying chain belt. The problems that in the prior art, the soil breaking and separating effects are poor in the rhizoma chuanxiong digging and harvesting process, which causes soil blockage and low stem exposure rate are solved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a multi-stage excavator for crushing Chuanxiong. Background technique [0002] Ligusticum chuanxiong belongs to rhizome traditional Chinese medicinal materials, which are mainly planted in Sichuan. The stems are 40-60 cm high and the rhizomes are well developed. They are about 5 cm below the soil. The tubers are irregular nodular fist-shaped lumps with a strong aroma. The Rhizoma Chuanxiong is harvested manually. First, the stalks on the ground are cut off, and then the Rhizoma Chuanxiong is dug out with a nail-toothed rake. Finally, the Rhizoma Chuanxiong is picked up and dried in the sun. [0003] The existing Chinese herbal medicine rhizome harvester is actually an excavator, and its excavation depth is relatively deep. When the soil moisture content of Chuanxiong is high and the soil is heavy, a large amount of soil and Chuanxiong enter the excavator, resulting in soil-C...
