Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a root vegetable digging machine, for example, a root vegetable digging trencher.

[0002]

2. Description of the Related Art Various trench trenchers have been proposed for digging root vegetables that have grown long and have a long diameter. For example, the actual applicant 4-65021 (actual application 2-109)
No. 626) is an attempt to efficiently harvest the long one without damaging the skin.

[0003]

[Problems to be solved by the device]

In the above-mentioned trencher, in order to dig up a long-length long pear without damaging it carefully, the bottom end of the root vegetable is excavated and the bottom of the root is dug up.
There was a problem that the amount of excavated soil and the amount of floating soil were large.

This large amount of excavated soil that is moved causes a great amount of hard work for an operator who grips and pulls out a long neck at the rear of the trencher. In order to solve this, one or two assistants are needed immediately before the harvester to scrape the excavated soil on the surface to one side or both sides to project the neck.

[0006]

[Means for Solving the Problems]

[0007] A base frame attached to the tractor, an excavating means attached to the base frame for excavating soil to a predetermined depth installed on the side of the root vegetable to be dug, and a base frame at the rear of the excavating means, the front part being rearward. The excavated body installed below the section, the input shaft rotated by the driving force of the tractor PTO shaft, and the rotation transmitted from the input shaft installed at the rear of the base frame in the traveling direction of the base frame. And a rocking motion converting mechanism for converting into a rocking motion on a surface intersecting with, and the tip is located on the upper part of the excavated body, and is rocked on a surface intersecting the traveling direction of the base frame by the rocking motion converting mechanism. Digging machine for root vegetables etc.

[0008] is provided.

When the digging machine according to the present invention is introduced into a field to start harvesting with cultivation ridges such as root vegetables, the excavating means excavates the side portions of the root vegetables. Then, the digging body located at the rear of the digging means lifts the root vegetables together with the surrounding cultivation soil. The tip of the removing means is located on the upper part of the dugout body and is rocked by the rocking motion conversion mechanism in a plane intersecting with the traveling direction of the base frame, so that the cultivation soil floating with the root vegetables moves from the surface layer to the side. Since it is continuously removed, the neck of root vegetables etc. projects. Therefore, the worker can easily grasp and pull out.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described.

FIG. 1 is a perspective view of the invention. The mission 12 is mounted on the base frame 4 and the drive sprockets 13 are arranged on the left and right. An input shaft 3 is connected to the TPO shaft of the tractor (not shown), and the eccentric shaft 11 at the rear end is rotated via the counter shaft 10 by the pulleys 8 and 8'between the upper parts. A boom 6 is fixed to the outside of the base frame 4 and is provided with a tension material to which the excavation chain 7 is attached. Reference numeral 2 denotes a mast stay, the base portion of which is pivotally attached to the base frame 4 and which forms a top hitch 1 at the front of the upper portion and is connected to one end of a hydraulic cylinder 9 at the rear. The other end of the hydraulic cylinder 9 has a base frame 4
The mounting angle of the mast stay 2 changes when the hydraulic cylinder 9 is expanded and contracted by being fixedly attached to the bracket projecting on the rear portion. 5
Is configured to be movable laterally with respect to the base frame by a lower pin.

An upper portion of the support bar 14 is fixed to the base frame, and a lower end of the support bar 14 is rotatably fixed to a front side portion of the dugout body 16. Reference numeral 15 is a connecting bar, the upper part of which is pivotally attached to the eccentric shaft 11 and the lower end of which is fixed to the rear part of the excavating blade body 16. Reference numeral 17 denotes a blade portion which has a plane chevron shape and constitutes the front portion of the excavating blade body to perform an oscillating motion.

Reference numeral 23 is a second counter shaft, and 10 is a counter shaft.
Transmitted from a pulley through. The rotation of the second counter shaft 23 drives the exclusion material 24 via 25 rotating rods.

FIG. 2 is a side view showing a cross section of excavation. The grown long haul moves with the surrounding cultivation soil and moves on the upper surface of the body. The long thighs are lifted up together with the surrounding cultivation soil, the surface layer is scraped off by the excluding material 24, and the long necks are projected.

FIG. 3 is a rear sectional view showing a dug state. 22 indicates the width of the excavation groove formed by the excavation chain 7,
Since the support bar 14 and the connecting bar 15 are propelled in this groove, the propulsion resistance is very small. By the rotation of the second counter shaft 23, the rotating rod of 25 causes the exclusion member 24 to swing as indicated by a dotted arrow. Reference numeral 26 is a base pin at the top of the excluding material.

[0016]

[Effects of the Invention] With the above configuration, even when digging long-rooted isotonic vegetables, the upper-layer excavated soil that has floated up along with the surrounding soil is continuously removed to the side. The person was able to easily grip the neck, and it was a light work.
