Problems solved by technology

Secondly, through the research and investigation of the above-mentioned existing yam harvester, it is found that there are two unrealizable problems in the current yam harvester: 1) The device still needs a lot of manpower to complete subsequent harvesting after ditching
2) In the follow-up manual harvesting project, it is easier to damage the tubers of yam
In this way, the integrity of Chinese yam can be improved, and the tuber of Chinese yam can be damaged as little as possible, but so far there is no equipment that can solve the above-mentioned technical problems, which is the weak point of the prior art

Abstract

The invention discloses a method for harvesting yam by means of a yam harvester. When the yam is harvested, two spiral drill rods are located on the two sides of one planting row of the yam, harvesting work of the first planting row is started, an input main shaft is connected with a tractor rear-axle output main shaft through a universal coupler, power is thus conveyed to a drive bevel gear, the drive bevel gear is meshed with a driven bevel gear, the driven bevel gear is fixed with a transmission main shaft, the transmission main shaft is thus driven to rotate, power is transmitted to a main transmission gear and then to a screw rod gear and spiral drill rod gears, and the spiral drill rods are thus driven to rotate; the screw rod gear is in key joint with a sleeve, an inner hole of the sleeve is in clearance fit with the outer cylindrical surface of a screw rod, the sleeve is connected with a lifting nut through a hinge, the lifting nut rotates in a following mode, the lifting nut is in threaded connection with the screw rod, the lifting nut is connected with a lifting platform through a bearing, the lifting platform is driven to descend, descending of the lifting platform drives descending of the screw rod gear, and power of the screw rod gear is provided by the main transmission gear.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a method for harvesting yams by a yam harvester. Background technique [0002] At present, there are three solutions to the problem of yam harvesting, namely: single-sided yam harvester; double-sided yam harvester; chain yam harvester. Secondly, through the research and investigation of the above-mentioned existing yam harvester, it is found that the current yam harvester has two unrealizable problems: 1) the device still needs a lot of manpower to complete subsequent harvesting after ditching. 2) In the subsequent manual harvesting project, it is easier to damage the tubers of Chinese yam. In order to overcome these problems, it is necessary to try to make the soil where the yam is located loose after the yam harvester ditches, so that the combination of the yam and the soil is no longer tight. After the installation operation, the process of manually collecting yams can ...
