Self-propelled green Chinese onion combine harvester

Abstract

The invention relates to agricultural machinery, in particular to a self-propelled green Chinese onion combine harvester. The self-propelled green Chinese onion combine harvester comprises a rack, a soil separating mechanism, a vibration excavating mechanism, a forming torsion mechanism and a quantitative laying mechanism, wherein the soil separating mechanism, the vibration excavating mechanism, the forming torsion mechanism and the quantitative laying mechanism are sequentially arranged on the rack from front to back; the vibration excavating mechanism is located below the soil separating mechanism; the digging mechanism comprises a digging shovel, a spring I, a permanent magnet, a coil and a sliding shaft; the rear end of the digging shovel is fixedly connected with the permanent magnet; the front end of the digging shovel faces the soil separating mechanism; the sliding shaft is sleeved with the spring I, the permanent magnet and the coil; the permanent magnet is located between the spring I and the coil; the two ends of the permanent magnet are fixedly connected with the spring I and the coil respectively; and the two ends of the sliding shaft are fixedly connected with the rack 1. The resistance in the green Chinese onion digging process is reduced, green Chinese onions are conveniently collected, and automatic harvesting of the green Chinese onions is achieved.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a self-propelled scallion combine harvester. Background technique [0002] At present, domestic self-propelled green onion combine harvesters are mostly improved with Japanese green onion harvesters as a reference template, but the soil in Japan is quite different from domestic soil. Japan has volcanic soil and the soil is relatively loose. The difference is large, mainly clay, so there are problems such as large excavation resistance, excavation backed up soil and difficulty in collecting green onions during the excavation process. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defect that prior art exists, has proposed a kind of self-propelled scallion combined harvester, and it has reduced the resistance in the scallion excavation process, is convenient to the collection of scallion, has realized the automatic harvesting of...
