Small self-propelled full-width seedling lifting harvester

Abstract

The invention relates to the technical field of traditional Chinese medicine processing, in particular to a small self-propelled full-width seedling lifting harvester. The harvester comprises a rack (20), a walking device (12), an excavating device (2), a conveying device (4), a depth limiting wheel (18), a screening device (8) and a collecting device (22). The conveying device (4) comprises conveying device side plates, a conveying chain plate (15), a first vibrating wheel (30), a toothed soil crushing roller (3), a supporting frame (7), a supporting frame (16), a rolling soil crushing roller(1) and a secondary toothed soil crushing roller (5). The depth limiting wheel (18) is rotationally connected to the front ends of the left conveying device side plate and the right conveying deviceside plate. The screening device (8) comprises screening device side plates, a screening chain plate (21), a second vibrating wheel (14) and a soil removing mechanism. The collecting device (22) is located at a discharging end of the screening chain plate (21). The harvester can adapt to growth characteristics of Ophiopogon japonicus, meet harvesting requirements of Ophiopogon japonicus, save manpower and material resources, and improve labor production efficiency.

Description

technical field [0001] The invention relates to the technical field of processing traditional Chinese medicinal materials, in particular to a small self-propelled full-width seedling harvester. Background technique [0002] Ophiopogon japonicus is a commonly used traditional Chinese medicine in China. It is widely used in TCM clinics and is also the raw material of various Chinese patent medicines and health foods. Modern pharmacological studies have shown that Ophiopogon japonicus mainly contains glucosides, steroidal saponins, alkaloids, sitosterol, glucose, amino acids, vitamins, etc., which have the effects of anti-fatigue, scavenging free radicals, improving cellular immune function and lowering blood sugar. In addition, Ophiopogon japonicus has sedative, hypnotic, anti-myocardial ischemia, anti-arrhythmia, anti-tumor effects, especially for improving the health of the elderly. Ophiopogon japonicus not only has high medicinal value, but also has high economic value. T...

Problems solved by technology

Among the patents and patent applications of these Ophiopogon japonicus harvesters, "Ophiopogon japonicus harvester", "A kind of Ophiopogon japonicus harvester", "Ophiopogon japonicus planting and harvesting device", "Ophiopogon japonicus fruit picking machine", "New type of Ophiopogon japonicus harvesting Both the "Automated Ophiopogon japonicus Harvester" and the "Automatic Ophiopogon japonicus Harvester" adopt a rear-mounted harvesting method. During the harvesting process, the traction machinery at the front will crush the Ophiopogon japonicus seedlings, damage the stems and leaves of Ophiopogon japonicus, and affect the growth of Ophiopogon japonicus. Branch propagation

In addition, the "automatic Ophiopogon japonicus harvester" uses paired drums to rotate and knead to remove soil, which will damage the tuber skin of Ophiopogon japonicus and affect the harvest quality of Ophiopogon japonicus.

"Step-by-step numerically controlled Ophiopogon japonicus excavator" and "A kind of Ophiopogon japonicus harvester" do not meet the agronomic requirements of Ophiopogon japonicus, and "A type of Ophiopogon japonicus harvester" cannot separate the tubers of Ophiopogon japonicus from the soil

[0005] Therefore, it is urgent to develop a kind of Ophiopogon japonicus harvester that meets the harvesting requirements, in order to solve the problems of high work intensity and low labor rate when Ophiopogon japonicus is harvested
