Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a straw harvester that cuts and travels a field by providing a mowing unit on a traveling machine equipped with a left-right traveling device.

[Conventional technology]

In this type of straw harvester, a support frame that supports the mowing device is attached to the traveling-machine-side frame at a rising portion located behind the mowing device.

[Problems to be solved by the device]

In such a structure, since the support frame is provided near the ground corresponding to the installation height of the mowing device, the rising part of the supporting frame is also at a low position, and the scraps after mowing are located at this rising part. When the wrapping and the wrapping waste lumps form an agglomerate, the stuffing straw grass may invade into the transportation route of the reaping straw grass that is transported to perform a selective action after cutting, and hinder the transportation state.

An object of the present invention is to provide a traveling device that can effectively use the traveling device to suppress the influence of scraps on the transportation of the mowing straw grass.

[Means for Solving the Problems]

The characteristic configuration according to the present invention is characterized in that a reaping unit is arranged in front of one traveling device of the left and right traveling devices equipped on the traveling machine body, and a support frame for supporting the reaping device of the reaping unit is attached to the traveling device of the one traveling device. The front end of the one traveling device is viewed from the side with respect to the point provided on both lateral sides so that the tip of the traveling device is inserted and the rising portion of the support frame located behind the mowing device. The traveling device is arranged so as to be superposed on or at the front, and the action and effect are as follows.

[Action]

The supporting frame is provided on both lateral sides of one traveling device in the left and right traveling device so that the leading end portion of the one traveling device enters and the front end of the one traveling device with respect to the rising portion of the supporting frame. By setting the position so that it overlaps in side view or by setting it so as to be located in the front, if the state where it overlaps in side view, the front end of the traveling device will be scraped around the rising part as the aircraft travels. The straw can be hooked, peeled off from the rising part and pushed into the ground, and if it is located in the front, the front end of the traveling device can be stomped before the winding as the aircraft travels. Since it can be pushed into the ground by pushing it up, there is no lump of dust and straw on the rising part.

[Effect of device]

Therefore, it is possible to reduce the amount of waste straw protruding into the movement path of the cut straw grass, and to carry the cut straw grass more smoothly. Moreover, the structure adopted for this purpose only needs to be modified such that the front end of the traveling device is arranged so as to overlap the rising portion in a side view or to be positioned in front of the rising portion. It has an advantage that it is not necessary to provide a dedicated tool for removing scraps.

As shown in FIGS. 2 to 4, the weeding device (1) revolves a rod (1a) pivotally supported at the upper and lower ends in a rearward tilted posture in a spindle shape about its pivot axis. It does the action of removing the entanglement of strawberries without rotating them.

Further, the raising devices (2) and (2) are equipped with a large number of raising and lowering claws (2c) attached to a chain (2b) wound around a pair of upper and lower sprockets (2a) and (2a). It is installed in a tilted posture. The holding and conveying device (5) has a pair of left and right holding belts (5a), (5a) of a lateral rotation type equipped with a scraping wheel (32), which are arranged side by side, and the belt (5) made of a soft material is provided.
In steps a) and (5a), it is held so that it does not damage the strawberries, and it is installed in a slightly upwardly inclined posture.

The feeding device (6) is composed of a blower device (6A) having a blowout port (6a) at the end position of the lateral feed conveying device (8), and blows the air discharged from the blower device (6A) laterally of the body. The strawberries are blown out in the horizontal direction, and the strawberries hung and conveyed by the holding and conveying device (5) are blown upward to send out the strawberries.

A pair of left and right mowing devices (3) from the mowing frame (33)
The horizontal portions of the support frames (17) and (17) extend forward at a height close to the field, and the weeding tool is supported at the tip thereof, and the rear end of the horizontal portion of the support frame (17) rises.
