Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] In order to make full use of the sandy soil characteristics of planting Chinese yam, the present invention at first provides a kind of root crop harvesting method, and it comprises the following steps:

[0040] refer to figure 1 , figure 2 Shown, at first cut the rhizome 200 both sides of Chinese yam and the soil 100 at the bottom, form section around the rhizome 200, make the soil (for example Figure 4 , Figure 5 The soil in 1000) is separated from the more distant soil.

[0041] Next, the soil (for example, the soil 1000 ) surrounding the crop rhizome is lifted. Preferably, the lifting process is gradual rather than abrupt vertical lifting.

[0042] Next, the lifted soil (for example, soil 1000) is dropped rapidly, and the sandy soil is broken up. The soil (such as soil 1000 ) surrounding the crop rhizome 200 is loose...

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 ...
