Convenient scarification green Chinese onion harvesting device and method

Abstract

The invention provides a convenient scarification green Chinese onion harvesting device and method, and relates to the field of crop harvesting equipment. The convenient scarification green Chinese onion harvesting device comprises a self-propelled chassis and a digging mechanism, the digging mechanism comprises a digging shovel and a pair of self-rotation augers rotatably connected to the two sides of the digging shovel, and in the advancing direction of the self-propelled chassis, the working ends of the augers extend out of the digging shovel in the axial direction; the digging mechanism isconnected with the self-propelled chassis through a connecting rod mechanism, the connecting rod mechanism drives the digging mechanism to act so as to change the included angle between the digging shovel and the self-propelled chassis and change the distance between the digging mechanism and the self-propelled chassis, and crawler walking wheels at the two sides of the self-propelled chassis canstably drive a harvesting mechanism to move in the manner that the self-propelled chassis is matched with the scarification harvesting mechanism; and the harvesting mechanism adjusts the depth and the burying angle through a connecting rod structure with the variable angle and length, soil loosening and digging are conducted in sequence, and lossless harvesting is guaranteed.

Description

technical field [0001] The present disclosure relates to the field of crop harvesting equipment, in particular to a convenient soil loosening device and method for harvesting scallions. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] In recent years, with the introduction of foreign advanced technology and the vigorous investment in scientific research in my country, many types of green onion harvesters have appeared on the market in my country. The standardization and mechanization of green onion production have become the key to the development of its industry, and restrict the production of green onion. The improvement of planting economic benefits has played a role in fueling the development of the harvest mechanization of green onions. [0004] For some of the existing green onion harvesters, part of the scheme is: the bottom of the...

Problems solved by technology

[0004] For some of the existing green onion harvesters, part of the scheme is: the bottom of the frame is equipped with a device that can pull up the green onions and transport them backwards, and during the transmission process, the green onions can be turned from vertical to horizontal. , but it also relatively increases the phenomenon that the onions are easy to break when harvesting; in addition, there is an adjustment mechanism connected to the frame, and a knife for loosening and loosening the soil is connected to the adjustment mechanism. The adjustment mechanism can drive the knife deep into the soil below the root of the green onion And drive the tool to vibrate, but the efficiency is relatively low and the stability is not high

[0005] The inventor found that the current side traction combine harvester is mainly suitable for large-scale farms in Europe and America, and the small self-propelled combine harvester is mainly suitable for Japanese and Korean family farms, with excellent performance; however, the overall cost of the combine harvester is relatively high, and the equipment is complicated. Large quantities of scallions are planted in the area, but during the harvest process, the method of direct excavation leads to a high damage rate of scallions, which makes it difficult to store and transport long-distance. Requirements, it is difficult to guarantee the non-destructive harvesting efficiency of scallions
