Description

Detailed Description of the Invention

[0001]

[Industrial field of application] The present invention relates to a configuration of a harvester in a state where roots such as edamame are rooted.

[0002]

2. Description of the Related Art As a method for harvesting edamame and the like, a method in which a root portion is cut and a stem portion is held and pulled out is generally known. Further, there is known a harvesting machine in which a device for picking up green soybeans at the same time as extracting is integrated. In recent years, for the purpose of preventing continuous crop failure, there has been demand for a harvester that promotes the discharge of roots from upland fields and harvests in a "rooted" form to maintain quality after harvesting.
As a known technique related to this "rooted" harvester, Japanese Patent Laid-Open No. 2001-103826 is known. According to this known technique, a walking self-propelled vehicle straddles a ridge in which beans are planted, and the beans are taken out with roots and equipped with a soil removing device.

[0003]

DISCLOSURE OF THE INVENTION In the above-mentioned known walking self-propelled vehicle body, each row of ridges is harvested, and after harvesting the harvested product, it is transferred to the next adjacent ridge and harvested. Below the pulling and conveying device, a landslide device for removing the soil attached to the lower part of the stem and the root during the conveyance by the pulling and conveying device and a soil removing device for removing the soil are provided. The former landslide device has a structure in which projecting teeth that enter into each other's loci protrude from the outer circumference of a pair of rotating counter-arranged drums around the vertical axis, and the latter landslide device rotates horizontally. It has a structure in which the disk is provided with a sand hitting plate, both of which have a complicated structure, and because the disk is forcibly disintegrated and forcibly cleared by rotational driving, there is a problem that the contact portion is largely worn.

[0004]

In order to solve the above problems, in a harvesting machine for extracting edamame or the like with roots, a digging body having a fork rod at the rear part for digging the root of the edamame and the digging body The oscillating means, the pulling / conveying device in which a pair of conveying bodies are inclined to hold and pull out the stem portion of the edamame etc. that has been dug up, and the striking rod is arranged in parallel with the conveying direction of the pulling / conveying device. It provides a harvesting machine for green soybeans, etc., which is provided with a soil removal for the root part. The edible soybean harvester is characterized in that the oscillating means of the dug up body and the oscillating action of the soil removing device are interlocked with each other.

[0005]

As described above, for example, when the harvester for edamame or the like of the present invention is installed and introduced into the cultivation ridge, a dugout body having a fork rod is inserted under the root of edamame or the like and rocks. So, as the root rises, loosen the soil mass attached to the roots of the roots and stems and break it. After the soil mass at the root is loosened and falls between the fork rods, the stalks of edamame or the like are held by the pulling and conveying device at the upper part of the fork rods and lifted. While being pulled out by the pulling-out transporting device and rising, the root of the root part was continuously beaten and adhered for a certain distance by the length of the tapping rod by the tapping rod arranged in parallel to the transporting direction of the transporting device. The soil is thrown away. Further, since the rocking force of the rocking means of the excavated body is used for the soil removing device, it is possible to achieve soil removing with a simple and lightweight structure without using a special power source of the soil removing device. .
