Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an excavator, for example, an excavator that excavates over multiple steps and then collects the harvested products of each step and then lets them dry on the ground in rows. .

(Prior Art) Conventionally, as this type of excavator, for example, as described in Japanese Utility Model Application Publication No. 54-53037,
A cross-feeding conveyor is pivotally attached to the rear part of the rear conveyor so as to be rotatable in the vertical direction, and guide bars on the left and right sides in the front-rear direction are located at the upper left and right sides of the discharge end of the rear conveyor, and the rear side is narrower. The arrangement is fixed in an inclined state, and during excavation work in the first step, the lateral conveyor is rotated upward to open the discharge end of the rear conveyor, and the left and right guide bars are inserted from this discharge end. During the digging work in the second step, the transverse feed conveyor is rotated downward and connected to the discharge end of the rear transport conveyor, and the harvested material is discharged directly rearward through the transverse feed conveyor. A structure is known in which the harvested material is transported horizontally and released toward the harvested product in the first step.

(Problem to be solved by the invention) In the structure described in the above-mentioned publication, during the harvesting operation in the first step, the discharge end of the rear conveyor is opened, and the harvested products are transported through the left and right guide bars at the discharge end. The material is guided toward the widthwise center of the rear conveyor and discharged to the ground, but at this time,
The left and right guide bars in the front-rear direction guide the harvest toward the center in the width direction on the rear transport conveyor and release it toward the rear, so the harvest is often scattered on the ground. This is undesirable because it gathers the crops and releases them in rows, and when the harvested products of multiple rows are neatly arranged in rows and air-dried on the ground, they become scattered on the ground, and each harvested product is picked up after being dried on the ground. There is a problem in that this is not desirable in terms of efficiently carrying out the picking up work.

Therefore, the present invention was developed in view of these points, and when the cross-feeding conveyor is not in use, the crops carried out from the rear conveyor can be collected on the ground and naturally released into rows. To provide an excavator capable of continuously carrying out excavation work without causing the harvested materials to be scattered on the ground, capable of reliably drying the harvested materials in multiple rows on the ground, and capable of continuously carrying out digging work. It is intended for this purpose.
