Sectioned type allium fistulosum harvester and harvesting method

Abstract

The invention relates to a sectioned type allium fistulosum harvester and a harvesting method. The harvester comprises a crawler chassis, a vibration type excavating device which is hinged to the rearend of the crawler chassis through a horizontal hinge shaft, and an allium fistulosum righting rod which is fixedly connected with the crawler chassis; a pushing device which drives the vibration type excavating device to rotate around the horizontal hinge shaft is installed on the crawler chassis and an engine which is used for driving the crawler chassis to move are installed on the crawler chassis, and the allium fistulosum righting rod extends to the side, located on an allium fistulosum passing route, of the vibration type excavating device. The harvester has the advantages that the operational functions of excavating, soil loosening, pulling and laying are achieved, flexible soil clearing and loosening and ordered laying are achieved, an excavating shovel is allowed to moved up anddown according to different working demands, the uniformity of the excavating depth is ensured, a rocking arm is driven by a motor to drive a soil screening net to vibrate, so that soil block pulverizing and soil clearing are achieved, the allium fistulosum gradually moves towards one side, and the ordered laying of the allium fistulosum is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a segmented green onion harvester and a harvesting method. Background technique [0002] my country is the largest green onion production area in the world. The harvesting methods are generally harvested by the growers themselves or hired labor. The harvesting cost is high, and the quality of manual harvesting is poor. It takes an average of 8 to 10 working hours for a grower to harvest an acre of green onions by himself. It costs an average of about 500 yuan per mu to hire a worker to harvest green onions, while the average cost of mechanized harvesting of green onions is only about 80 yuan per mu. If the mechanized harvesting of green onions is implemented, only the harvesting of green onions will save about 3.3 billion yuan in costs for the nearly 8 million mu of green onions in the country, which will greatly reduce the production cost and promote...

Problems solved by technology

[0003] However, the equipment currently used for harvesting scallions is not mature enough. The patent application number 201510632401.3 discloses a scallion harvester. Although the harvester has a vibrating digging shovel, it does not have the effect of vibrating and shaking the soil, resulting in incomplete soil removal from the roots of scallions.

The patent with the application number 201720368228.5 discloses a self-propelled green onion harvester. Although the soil is crushed and leveled, the green onions are not excavated from the soil. large volume, low efficiency

Therefore, harvesting has become a weak link in the whole process of mechanized production of green onions, which seriously restricts the development of the whole process of mechanized production of green onions
