Abstract

PROBLEM TO BE SOLVED: To enable the easy and quick practice of operations to uproot floated root vegetables from the ground by relaxing a holding power of the surrounding soil for the root vegetables to be floated while retaining the advantage in halving the traction force and reducing the sinking of root vegetables when passing spade units through the soil. SOLUTION: A pair of spade unit P opposite in the shape of an inverted chevron when viewed from the front together with shanks 20 supporting the spade units P are passed through soil on both left and right sides near roots of cultivated rows of root vegetables R while being vertically vibrated with a vibrating mechanism (d) to hold and lift the root vegetables R together with soil S around the root vegetables R by the pair of spades P. The lifted and moved soil S is shaken by the movement of the vertically moving shanks 20 and the rear end sites of the spade units P moved in the direction opposite to the spade units P and settled ahead of the root vegetables R so as to make the lifted root vegetables R held with the settled soil S. Thereby, the root vegetables R are kept in a state of the heads protruding from the soil S long.

A pair of plows P on both sides of the cultivation line of root vegetables R ... such as burdock
・ Pod is positioned so that P is located, and the plow P ・ P
As shown in the above, the root vegetables R ... are passed through the ground at the left and right sides of the cultivation line, and the root vegetables R ... are moved toward the surface of the ground while holding the soil S where they are vegetated, Root vegetables can be easily extracted afterwards.

[0005]

The root vegetable harvesting means performed by using the root vegetable harvester A of the above-described embodiment is such that the shank 20, 20 and the plow body P, P are integrated by the operation of the vibration mechanism d. When the root crop R is lifted up to the ground surface along with the soil through a pair of plows P and P in the ground near the right and left roots of the cultivation line of the root crop R, since the root crop R is vibrated vertically.
20 and the traction force of the plow P is reduced to half by the vibration, but the root vegetables R are lifted together with the soil S while being held in the surrounding soil, so that the root vegetables are lifted. R is strongly bonded to the soil, and in the case of a viscous soil, the root set R is settled together with the soil S due to the subsidence of the soil performed when the plow P * P passes. Class R
In the work of grasping the head of ... and pulling it out of the ground, the root vegetables R are often broken, and the pulling of the root vegetables R requires a great amount of pulling force. There is a problem that takes time.

The present invention has been made in order to solve this problem which has occurred in the conventional means, and a pair of plows of a harvester are passed under the root of root crops to remove the root crops. While retaining the benefit of halving the traction force when floating on the ground, loosening the holding power of the surrounding soil S on the root vegetables R ... An object of the present invention is to provide a new means for easily and quickly performing the work of extracting the raised root vegetables from the ground.
