Description

[Detailed Description of the Invention] [Industrial field of application] The present invention cooperates with a bundling culm bundle by a chain with protrusions and a holding rail urged toward the side of the protrusions within a predetermined range. The present invention relates to a stem-culd bundle collecting device provided with a lifting and conveying mechanism that nips and conveys upward and rearward in a sideways posture.

[Conventional technology]

Conventionally, as disclosed in Japanese Patent Laid-Open No. 63-198918, a stem-culm transfer passage between a chain with protrusions and a sandwiching rail in a lifting / conveying mechanism has a width in the free state of the sandwiching rail. A technique is known in which the bundle is formed to have the same length over the entire length excluding the inlet and the outlet.

[Problems to be solved by the device]

The lifting / conveying mechanism is designed to urge the nipping rail toward the chain with protrusions so that the stem culm bundle supplied between the two can be hooked with the protrusions of the chain with protrusions and lifted and conveyed upward. is there.

In other words, although the stalk bundle is maintained to be conveyed by the pressing action by the urging of the nipping rail, it has been found that the conventional technique has the following problems.

The stem culm bundle supplied from the inlet part is initially cylindrical, but it tends to gradually deform into a long cylindrical shape due to the pressing force of the nipping rail, and therefore the nipping rail is biased. However, it has been recognized that the culm bundles may be disturbed or dropped due to insufficient clamping force at the upper part of the transfer passage depending on the dispersion of the culm bundles and the binding force of the tying machine.

Therefore, in order to solve the above problem, it is possible to prevent the lowering of the clamping force in the upper part of the transfer passage by increasing the urging force of the clamping rail, but this time, the clamping force in the lower part of the transfer passage becomes stronger than necessary. As a result, resistance increases, which leads to new problems such as a decrease in transport efficiency and a difficulty in supplying the stalk bundle to the inlet.

In view of the above situation, an object of the present invention is to provide a stem culm bundle recovering device capable of surely conveying the stem culm bundle in the upper portion of the transfer passage without lowering the conveying efficiency of the lifting and conveying mechanism.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides the stem-cule bundle collecting device described at the beginning, in which the width of the stem-cullet bundle transfer passage formed between the chain with protrusions and the sandwiching chain is set to the width of the sandwiching rail. In a free state, it is characterized in that it is gradually narrowed toward the lower side of conveyance over the entire length excluding the inlet and outlet of the culm bundle.

[Action]

According to the above configuration, the width of the transfer passage can be adjusted to the cross-sectional change of the stalk bundle, so that the clamping force of the stalk bundle in the lifting / conveying mechanism can be reduced to the entire length excluding the inlet and outlet of the stalk bundle. Can be kept constant over time.

[Effect of device]

Therefore, since the clamping force in the upper part of the transfer passage can be made to be a sufficient value, it is possible to prevent the phenomenon such as the disturbance of transportation and the falling of the stem culm bundle, and the clamping force in the lower part of the transfer passage becomes unnecessarily strong to improve the transfer efficiency. Since it was possible to avoid lowering, it was possible to realize a stalk-and-bundle collecting device having a lifting and conveying mechanism with superior performance compared to the conventional one.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings, showing a case where the present invention is applied to a mowing and binding machine with a collecting device.

As shown in FIG. 3 and FIG. 4, the harvesting section (A) of the same type as the combine is attached to the front part of the traveling machine based on the combine, and the binding device (B) is provided at the rear part thereof, and further after that. To the left and to the left of the control unit (1)
, And a receiving and discharging part (E) at the upper end of the lifting and transporting mechanism (C), and a collecting part (D) at the rear of the receiving and discharging part (E). A shaving and binding machine is configured.

The cutting pretreatment unit (A) is a raising device (2) that causes planted grain culms, which is a type of stem culm, a pair of packers (3), (3) that scrapes the caused grain culm into the center, A mowing device (4) for mowing the collected grain stalks, and a vertical transport device for transporting the harvested grain stalks backwards and upwards while gradually lying down.
It is composed of (5) etc.

As shown in FIGS. 1 and 2, the lifting and transporting mechanism (C)
Is provided with a chain case (6) in a posture in which the chain case (6) is tilted upward and slightly rearward, and extends between the lower drive sprocket (7) and the upper driven sprocket (8) that are axially supported in the chain case (6). The chain with protrusions (9), and the chain with protrusions (9) exposed from the chain case (6) to the front side.
A sandwiching rail (10) is provided along the structure.

More specifically, the chain with protrusions (9) and the holding rail (10)
A path (11) is formed between and for transferring the stem culm bundle sent from the binding device (B) to the receiving and discharging part (E), and the width of this path (11) is In the free state where nothing is caught between the clamp rail (10) and the chain with protrusions (9),
Gradually the entire length excluding the inlet part (12) that receives the stem culm bundle from the bundling device (B) and the outlet part (13) that sends the stem culm bundle to the receiving and discharging part (E) toward the lower side of conveyance. It is configured to be narrow.

The holding rail (10) is provided with upper and lower support rods (14) and (14) arranged around the chain case (6) so as not to interfere with the bundle of stalks for conveyance, so that the chain with protrusions (9) side. The springs (15) and (15) are supported so that they can be biased within a predetermined range.

The nipping rail (10) in the inlet portion (12) is bent so that the lower end of the passage (11) is largely opened so that a bundle of stalks to be supplied can easily enter, and the outlet portion (13)
The nipping rail (10) in (1) is also bent so that the upper end of the passage (11) is widened in order to smoothly receive the bundle of transferred stems and send it to the discharge part (E).

In addition, the shaft of the driven sprocket (8) is attached to the chain case (6).
A rotary tool (16) for extending the grain outwards and for attaching and lifting grain culm is attached to the end on the side of the tip, and a large-diameter rotary shaft (17) that is rotationally driven integrally with the shaft on the stocker side. ) Is fitted. Further, behind the upper end of the lifting / conveying mechanism (C), in other words, behind the terminal end, the grain culm bundles discharged from the mechanism (C) are laid down sideways and temporarily received, and then discharged to the collecting section (D) at once. A stop release (E) is provided.

Therefore, the grain culm bundle supplied to the grain culm inlet portion (12) is clamped by the chain with protrusions (9) and the clamp rails (10), and is conveyed upward and rearward in a sideways posture. Tool (1
