Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled vegetable harvesting machine that extracts and transports various vegetables such as cabbage and Chinese cabbage, which are planted in a field, by an extracting and transferring device.

[0002]

2. Description of the Related Art A crawler-type self-propelled harvesting unit provided with a pulling-out transfer device for pulling out various vegetables such as cabbage and Chinese cabbage planted in a field from the field and transferring the vegetables obliquely upward. 2. Description of the Related Art There is known a vegetable harvesting machine that extends toward the front of a vehicle body and collects vegetables picked up and transferred by a harvesting work unit on a loading platform (for example, Japanese Utility Model Laid-Open No.
122556).

[0003]

By the way, vegetables such as cabbage and Chinese cabbage are generally planted on the ridges in a field. Therefore, the above-mentioned vegetable harvester must inevitably run in a ridged field, and after harvesting, it is necessary to break the ridge and level the land. In the case where there is no levee breaking means, the levee breaking work must be performed separately and the work efficiency is not good, and also, when the crawler traveling device of the vegetable harvester does not match the ridge spacing during harvesting work To
It was not possible to correct the posture of the vegetable harvester by breaking the ridges, and to move the vegetable harvester in the field with an appropriate posture.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems, and in order to achieve this object, a vegetable planted in a field is sandwiched between the vegetables. In a vegetable harvester having a pulling-out transfer device that is pulled out from a field and extending toward the front of the body of a self-propelled vehicle equipped with a crawler running device, a crawler running in a space below the pulling-out transfer device A vegetable harvesting machine equipped with a ridge breaking machine that breaks the ridge after the vegetables are pulled out near the front end of the device.

A ridge breaking machine for breaking a ridge after vegetables are pulled out is a vegetable harvesting machine provided near the rear end of a crawler traveling device at the rear end of a vehicle body.

[0006] Further, after the vegetables have been pulled out, the vicinity of the front end of the crawler traveling device in the space below the pulling-out transfer device and the vicinity of the rear end of the crawler traveling device in the rear end of the vehicle body. Vegetable breakers that break the ridges are arranged respectively, and a vegetable harvester with different working depths of both levee breakers is used.In addition, the above-mentioned both levee breakers are positioned in the width direction of the self-propelled vehicle. It is a vegetable harvester arranged differently.
