Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stem and stalk bundle collecting and releasing apparatus for collecting and severing bundles of stalk and stalk bundles in a cutting and binding machine such as a binder and releasing the bundle to the field.
More specifically, the present invention relates to a technique for reliably collecting stem and stem bundles and a technique for reliably releasing the stems.

[0002]

2. Description of the Related Art As a conventional stalk / culm bundle collecting / discharging device, a binder device disclosed in Japanese Utility Model Laid-Open No. 59-628 is known. In other words, a thin front and back stock bar for receiving the stem of the bundle of stems and stems after bundling from below, a backrest surface, and a lateral spike receiving portion are arranged on the lateral outside of the binding device. By feeding the stem stalk bundle backward by the accompanying movement due to the contact between the lower end of the stalk and the ground with the progress, three to four stem stalk stalks are collected on the stock bar. Then, the tip receiving portion is swung downward around the left and right axes to release the support of the tip side portion, thereby causing the three to four stem culm bundles to fall laterally outward to be released.

[0003]

The prior art stem and stalk bundle collecting and discharging apparatus uses the relative movement with respect to the ground and the gravity due to the progress of the airframe to collect several bundles without special power and to collect the ground. It is an economical means that can be released upwards, but there is room for improvement in terms of operational certainty. That is, as shown in FIG. 6 of the above-mentioned publication, the lower end of the stem and stalk bundle is slid on the stock receiving rod (reference numeral 22) by a drag action by contacting the lower end with the ground. On the other hand, if the ground has irregularities or undulations, the dragging and transporting action of the stem culm bundle becomes difficult to be exerted, and the released stem culm bundle may be clogged at a lateral position of the bundling device.

Further, since the releasing operation when the tip receiving portion is swung downward is a relatively passive means of utilizing the natural falling action of the stem and stem due to gravity, in some cases, the releasing operation is performed laterally outward. When the transfer force becomes insufficient and the stems are dragged to scatter the stem stalk bundle on the ground even after falling to the ground, the stock receiving rod and the stock wiping rod (reference numeral 23 in the drawings of the aforementioned publication) ) And could continue dragging. An object of the present invention is to re-examine the stalk stalk bundle collection and release device so that the stalk stalk bundle can be reliably collected without clogging, and the stalk stalk bundle can be reliably released onto the ground without being dragged. is there.

[Means for Solving the Problems]

[Configuration] A first invention is directed to a mounting portion capable of receiving and mounting a stem of a stem stalk bundle released from the binding device toward the lateral outside of the body, and a stem mounted on the mounting portion. A head receiving portion for supporting and supporting the tip side portion of the culm bundle, the culm bundle collecting mechanism capable of placing and holding the tied stem culm bundle in a standing upright posture, and comprising the culm bundle collecting mechanism. A forced release mechanism is provided for forcibly releasing and transferring the placed and held stem-and-stem bundle toward the outside of the machine, and the collected stem-and-stem bundle is allowed to fall laterally outward on the outer end side of the tip receiving part. Provide a receiving member capable of switching the posture between the action posture to prevent and the retreat posture to allow lateral and lateral movement, and the receiving member is in the operation posture when collecting the stem / culm bundle in which the forced release mechanism does not operate, and , So that the catching member is in the retracted posture when the stem-and-stem bundle is released when the forcible release mechanism operates,
The receiving member and the forced release mechanism are linked.

A second invention is configured such that, in the first invention, the operation of switching the posture of the receiving member from the operating position to the retracted position when the stem / culm bundle is released is performed by a downward movement of the receiving member due to its own weight. It is characterized by having.

According to the structure of the first aspect, the bundle of stems and culms after bundling is sequentially fed by the releasing operation of the bundling device and collected on the mounting portion, and is brought into contact with the ground as in the conventional case. Since this does not cause the feeding action, the stem culm bundle can be collected in the mounting portion regardless of the unevenness or unevenness of the ground. Since the stem stalk bundle placed and held in the stem stalk bundle collection mechanism is forcibly released by the forced release mechanism, there is no possibility of being in an incomplete release state such as dragging the collapsed stem stalk bundle for a while as in the past, The stem stalk bundle can be quickly and reliably discharged onto the ground.

[0008] Since the receiving member is provided on the outer end side of the tip receiving portion, it is possible to prevent the stem and stalk bundles collected in the mounting portion from falling down laterally and outwardly, so that an accident from the mounting portion can be prevented. Can be collected without falling. Then, at the time of release after the forced release mechanism is activated, the receiving member retreats and moves, so that the stem and stalk bundle can be satisfactorily released laterally outward without the receiving member becoming an obstacle.

According to the second aspect of the present invention, the posture switching operation from the working posture of the receiving member to the retracted posture when the stem / culm bundle is released is performed by the descending movement of the receiving member by its own weight. Therefore, it is not necessary to distribute the power for forcibly releasing the retreating movement of the receiving member. Therefore, it is possible to improve the driving efficiency by enhancing the release action or reducing the power loss.

Further, even if the power for returning the lowered receiving member to the original position is provided by the power for returning the forcible release mechanism, a relatively large output is not required at the time of release. Thus, the receiving member can be sufficiently returned and moved without requiring power more than the output required for forced release.

[Effect] Also in the mowing and binding machine according to claim 1 or 2, the stalk and stalk bundle collecting mechanism for placing and collecting the stalk and stalk bundle and the forced release mechanism for forcibly releasing the stalk and stalk bundle are adopted. A stalk stalk bundle collection and release device that operates more reliably, with a reliable stalk stalk bundle collection action without clogging of the stalk and lumps during collection, and a reliable stalk stalk bundle release action without dragging. was gotten.

In the stem-and-culm bundle collecting and releasing device according to the second aspect, the structure in which the receiving member is switched to the retracted posture by its own weight descends has the advantage that the driving efficiency of the forced release mechanism can be improved. .
