Excavator for Chinese medicinal herbs

Abstract

The invention provides an excavator for Chinese medicinal herbs. The excavator comprises a frame and a transmission system, wherein the frame is provided with a roller shaft; two ends of the roller shaft are respectively provided with a ground roller; the frame is provided with a hanging device; the front end of the frame is provided with a soil shoveling mechanism; a vibrating sieve device is arranged at the rear of the soil shoveling mechanism and connected with the frame through a crank rocker mechanism; the frame located at the rear of the vibrating sieve device is obliquely provided witha front soil-sieving conveying device; the frame located at the rear of the front soil-sieving conveying device is obliquely provided with a rear soil-sieving conveying device; the frame located abovethe central part of the front soil-sieving conveying device is provided with a first pressure roller device which matches with the front soil-sieving conveying device; and the frame located above thecentral part of the rear soil-sieving conveying device is provided with a second pressure roller device which matches with the rear soil-sieving conveying device. The excavator provided by the invention is a Chinese medicinal herb excavating and harvesting combined machine which can complete a plurality of processes like deep loosening, soil sieving and soil-herb separation by one time.

Description

technical field [0001] The invention relates to the technical field of Chinese herbal medicine planting agricultural machinery, in particular to a combined Chinese herbal medicine excavator for deep loosening of soil and separation of medicine and soil in dry farming areas in Northwest China. Background technique [0002] Chinese herbal medicine is an important economic crop in my country, with a wide area of ​​cultivation, high yield, good economic benefits, and strong adaptability to the environment. Its cultivation spreads all over the country, especially in the arid agricultural area of ​​Northwest China, the planting area of ​​Chinese herbal medicine is increasing year by year. However, most Chinese herbal medicines are planted in terraced fields, hillsides and small horizontal plots, and it is difficult to mechanize the whole process of production of Chinese herbal medicines.

AI Technical Summary

Problems solved by technology

However, most Chinese herbal medicines are planted in terraced fields, hillsides and small horizontal plots, and it is difficult to mechanize the whole process of production of Chinese herbal medicines.

[0003] At present, the harvesting mode of Chinese herbal medicine excavators has been widely promoted. The manual digging and harvesting mode is labor-intensive, low in efficiency, and easy to delay the farming time. However, there are few existing Chinese herbal medicine digging machines, such as the serious shortage of Chinese herbal medicine digging machines in the dry farming areas of Northwest China The existing mechanical reliability is poor, the degree of mechanization is low, and the leakage of excavation is serious, which cannot meet the current needs of efficient excavation of Chinese herbal medicines. In addition, the geographical environment for planting Chinese herbal medicines in the dry farming areas of Northwest China is complex, and most of them are terraced fields, hillsides, and small plots. For this reason, We designed a Chinese herbal medicine excavator according to the agronomic requirements and planting environment of the dry farming area in Northwest China. This machine has strong adaptability, good reliability, high degree of mechanization, and low excavation rate, which effectively reduces the cost of Chinese herbal medicine harvesting and improves operating efficiency. , effectively alleviated the pressure of the busy season of Chinese herbal medicine, and played a positive role in promoting the Chinese herbal medicine industry in the dry farming area of ​​Northwest China
