Rhubarb digging machine and its digging method

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a rheum officinale digging harvester and a digging harvest method thereof. The rheum officinale digging harvester comprises a rack, a stalk cutting mechanism, a stalk pulling mechanism, a first collecting box, a double-rod hydraulic drive, a digging and cutting assembly, a conveying mechanism, a second collecting box and a water tank; the stalk cutting mechanism and the stalk pulling mechanism are installed at the front portion of the rack, the first collecting box, the double-rod hydraulic drive and the water tank are installed in the middle of the rack, and a conveying belt I for conveying rheum officinale stalks is arranged between a stalk lifting mechanism and the first collecting box; the double-rod hydraulic drive comprises an oil pump and double oil cylinders in output connection with the oil pump, each oil cylinder is provided with an oil cylinder push rod, the oil cylinder push rod locatedat the front portion of the rack is connected to the digging and cutting assembly, and the second collecting box includes an outer box and a cleaning box located in the outer box. By means of the rheum officinale digging harvester, the mechanized harvest of rheum officinale is achieved, the harvesting efficiency is improved, and the harvester is reasonable, simple and compact in mechanical structure, convenient to manufacture and flexible and convenient to control and operate.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a rhubarb digging machine and a digging method thereof. Background technique [0002] Rhubarb is a collective name for various perennial plants of the Polygonaceae Rhubarb genus, and it is also the name of Chinese medicinal materials. In Chinese literature, "rhubarb" often refers to horseshoe rhubarb. Rhubarb is excavated at the end of autumn when the stems and leaves wither or before germination in the next spring. Remove fine roots, scrape off the outer skin, cut flaps or segments, string them into strings and dry or directly dry. The traditional Chinese medicine rhubarb has the functions of attacking stagnation, clearing damp and heat, purging fire, cooling blood, removing blood stasis, and detoxifying. Rhubarb planting is generally transplanted after seed propagation. Generally, the row spacing is 70-120 cm, the plant spacing is 60-100 cm, and the hole depth ...

AI Technical Summary

Problems solved by technology

Here, since soil removal and cleaning cannot be carried out while digging and harvesting, subsequent processes need to continue to clean the roots, and the efficiency of digging and harvesting is low, which not only increases the labor load, the input cost of the grower, but also prolongs the harvest. cycle
