Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a mowing section for raising and cutting a planting stem culm in the front of the machine body so as to be able to swing up and down around a horizontal axis, and to this mowing section, A bundling device for bundling the cut stalks and a lifting and transporting device for transporting the bunched stalks to the upper rear in a laid posture are provided at the rear lower part of this lifting and transporting device and the stalks dropped and released from this device. The present invention relates to a mowing and binding machine with a collecting device, which receives and stacks a culm, and is provided with a collecting section capable of dumping around a rear fulcrum.

[Conventional technology]

In the above-mentioned conventional tying and binding machine, for example, the actual cutting shovel 63-173
As shown in Japanese Laid-Open Patent Publication No. 028, the lifting / conveying device was integrally attached to the mowing section.

[Problems to be solved by the device]

However, in the above-mentioned cutting and binding machine, when the cutting height of the stalks is changed and the cutting section is rocked up and down so as not to damage the ground by coming into contact with the ground when traveling on the road or crossing a ridge, the lifting and conveying device. Will also swing together. In addition, in order to effectively load the bundled stem culms in the rear collecting section, the lifting / conveying device is vertically installed in a rearward inclined posture so that the upper part thereof is located above the collecting section in the normal cutting operation state. When the cutting unit is lifted and moved to the stalk collecting place at the end, the rearward inclination angle of the lifting and conveying device becomes large. As a result, when dumping the recovery unit to release the stem culm, the recovery unit may come into contact with the lifting / conveying device.Therefore, it is necessary to set the recovery unit to a small front-rear length. Had the drawback of being constrained.

An object of the present invention is to solve the above-mentioned inconveniences by simply improving the structure without increasing the overall length of the machine body.

[Means for Solving the Problems]

A feature of the present invention resides in that in the harvesting and binding machine with a collecting device described at the beginning, the lifting and conveying device is configured to be swingable around a lower lateral driving shaft core of the lifting and conveying device, and the lateral driving shaft core is provided. Via a link, the lower end of the exterior case of the lifting and conveying device and the lower front part of the machine frame are pivotally connected via a link, A unequal-sided four-link mechanism is formed between the horizontal axis and the lateral drive axis and the pivots at both ends of the link so that the upper part of the lifting and conveying apparatus swings forward as the upper and lower parts of the link move. At some point,
The action and effect are as follows.

[Action]

The lateral drive shaft core of the lifting / conveying device is fixed in position relative to the mowing unit, and the pivot frame fulcrum of the link and the horizontal shaft core as the swinging shaft core of the mowing unit are relative to the machine body. Since the position is fixed, if you swing the cutting unit up and
The lateral drive shaft core oscillates around the lateral shaft core to deform the quadruple link shape, and connects the lateral drive shaft core to the outer case side pivotal fulcrum of the link that determines the attitude of the lifting conveyance device. The link side swings forward, and the upper portion of the lifting / conveying device is swung forward.

[Effect of device]

As a result, the lifting / conveying device standing upright in the rearwardly inclined posture toward the upper part of the collecting section swings in the direction in which the rearward inclination angle becomes smaller during the collecting movement, that is, when the pre-mowing processing section is raised, so that the collecting section. At the time of dumping, it will be separated from the turning locus. Therefore, it is possible to prevent interference with the lifting / conveying device even if the length of the front and rear of the recovery unit is increased without increasing the overall length of the machine. Moreover, a very simple structural improvement in which the case of the lifting and conveying device and the body frame are pivotally connected by a single link is sufficient.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

3 and 4 show a mowing and binding machine with a collecting device according to the present invention. This reaping and binding machine raises and lowers the horizontal stem (P ₁ ) around the horizontal axis (P ₁ ) at the front part of the combine-based traveling machine body by expanding and contracting the hydraulic cylinder (1) to cause the planting stem culm. While connecting the mowing unit (2),
A bundling device (3) for bundling the cut stalks is disposed on the left rear side of the mowing part (2), and the bundling stalks are lifted and conveyed rearward and rearward of the bundling device (3) to open the upper recovery part. A lifting / conveying device (5) for dropping and collecting is provided in (4).

The mowing unit (2) guides the stalks to be mowed by the weeding tool (6) at the front end, and the raising device (7) raises the lodging stalks to the standing posture, and then the clipper type cutting device ( In 8), the plant is cut and mowed, and the cutting stem culm is scraped by the packer (9), and the rear vertical transfer device (10) is installed.
With this configuration, the mowing stem culm in the vertical position is gradually conveyed to the bundling device (3) while changing its position to the sideways falling position.

The recovery part (4) is provided so that it can be dumped around the rear fulcrum (P ₂ ). More specifically, the recovery part (4) has a box shape with an open upper part, and is pivotally supported on the body frame (11) around a rearward sideways fulcrum (P ₂ ) below the rear part, , A hydraulic cylinder (12) is pivotally connected between the middle of the bottom surface and the machine frame (11).
By extending and retracting (2), it is possible to switch between a recovery work posture in which it is stably placed on the machine body frame (11) and a discharge posture in which the front part is swung upward. And the rear wall (13)
Is provided so as to open rearward as it swings up and down.

The lifting / conveying device (5), as shown in FIG.
Inside the outer case (14), the chain with protrusions (17) is wound around the lower drive wheel (15) and the upper driven wheel (16) for interior mounting, and from the front side of the outer case (14). The chain (17) is exposed, and the sandwiching rail (18) is arranged so as to face the exposed chain (17). While the binding stem culms are sandwiched between the chain (17) and the sandwiching rail (18). It is configured to be lifted and transported. Also, in order to efficiently collect the stem culm by dropping it from the upper end into the collecting part (4),
The upper part is erected with the rear part inclined.

The lifting conveyance device (5) is the lifting conveyance device (5).
