Rhizome crop harvesting method and device

Abstract

The invention provides a rhizome crop harvesting method and device. The method comprises the following steps of: segmenting soil on two sides and the bottom of a crop rhizome, and forming a fracture surface around the crop rhizome; lifting soil which surrounds the crop rhizome; quickly lowering the lifted soil; and ensuring that the soil which surrounds the crop rhizome is loose, and pulling out the crop rhizome along the upper end of the crop rhizome or the plant of the crop rhizome. The method fully utilizes the characteristic that the soil in which the rhizome crops, including Dioscorea oppositifolia L. and the like are planted, is loose and fragile to integrally segment the soil which surrounds the Dioscorea oppositifolia L., then, the soil is quickly thrown, the sandy soil which is fragile is decomposed after being knocked, and at the time, the Dioscorea oppositifolia L. can be easily pulled out. Therefore, no furrows need to be dug, a vibration mechanism does not need to be arranged, a transmission mechanism with a complex structure is not used, an integral structure is simple, and manufacturing and repairing are simple and easy to implement.

Description

technical field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a root crop harvesting device. Background technique

[0002] Rhizome crops refer to potatoes, sweet potatoes, yams, etc. It is quite difficult to harvest due to the deep burial, especially yams, because the rhizomes of yams grow upright in the soil and are about one meter long. Such as figure 1 , figure 2 As shown, the rhizome 200 of yam grows upright on the soil 100 , and the plant 201 of yam grows and extends on the surface of the soil 100 . When planting yams, they are generally planted in ridges, such as figure 1 , which can facilitate planting, harvesting and increase yield per mu.

[0003] Because the root crops of yam are long and penetrate deep into the soil, the traditional harvesting method is generally manual harvesting, which requires digging deep ditches in the soil and cannot break the rhizome of yam 200, resulting in huge labor costs. (this is ...
