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.

[0005]

[Means for Solving the Problems]

[Structure] In the first invention, a placing portion capable of receiving and placing a stem of a stem-and-stem bundle released from the binding device toward the lateral outer side of the body, and being placed on the placing portion. A head receiving portion for leaning and supporting the tip side portion of the stem and stalk bundle to constitute a stem and stalk bundle collecting mechanism capable of placing and holding the stem and stalk bundle after bundling in an upright posture,
The tip receiving part in the state of supporting the stem and stem bundle in the forward and backward falling posture,
By being configured to be rotatable around the vertical axis of the vertical provided on the lateral outer side, by driving and rotating the head receiving portion around the vertical axis from the collecting action posture for receiving the head side of the stem stalk bundle,
A compulsory release mechanism that forcibly releases the stem and stalk bundles placed and held on the stem and stalk bundle collection mechanism toward the outside of the aircraft,
A hook portion is provided at an end of the head receiving portion on the side of the machine body, the hook portion being capable of hooking a stem-and-stem bundle in a leaning posture and pushing in a forced releasing direction in accordance with the release rotation of the head receiving portion.

According to a second aspect of the present invention, in the first aspect, a stock former payment member protruding at a base portion of a placement portion of the body in a base portion of a release movement path of a stem and stalk bundle released from the binding device. And the height level of the stock former payment member can be adjusted up and down.

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 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 tip receiving portion for supporting the tip side portion is supported, the tip receiving portion is rotated to forcibly release the tip.
There is no need to provide a release member separately from the tip receiver,
This makes it possible to reduce the size of the stem and stem collecting and discharging device, and also to reduce the number of parts and cost.

Further, a hook portion is provided at the end of the head receiving portion on the side of the fuselage so as to hook the stem stalk bundle in a leaning posture in accordance with the release rotation of the head receiving portion and to push the bundle in the forced release direction. At the time of forcible release of the stem stalk bundle with the rotation of the tip receiving portion, if there is a stem stalk bundle that moves and moves off the tip receiving portion during rotation due to centrifugal force, the hook portion moves away from the stem portion. He catches the bundle and pushes it. That is, it is possible to reliably perform the forcible discharge action by preventing the operation failure due to the centrifugal force from occurring, while having the structure for forcibly releasing by rotation.

[0010] According to the second aspect of the present invention, since the base paying member acting on the base of the stem stalk bundle released from the binding device is provided at the base position of the mounting portion of the body, the stem stalk bundle is provided. When the collection and release device is not installed, the stem of the stem and stalk bundle released from the binding device is hooked to give resistance, and can be released outside the machine while falling sideways ahead of the tip side, and the release position on the ground Can be satisfactorily performed in a state in which they are aligned.

[0011] When the stem-and-stem bundle collecting and releasing device is mounted, the installation height of the stock former payment member can be reduced so as not to obstruct the stem and stem bundle moving from the binding device to the mounting portion. It is possible to transfer the stem and stalk bundles to the mounting portion without falling down on the way. In this way, even when the stock prepayment member is not required, the portable device is carried around the body, so that it is not forgotten to be attached or detached and the risk of loss is reduced as compared with the means for attaching and detaching. Is desirable.

[Effect] In the cutting 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. As well as obtaining a reliable stem stalk bundle collection action without stem stalk clogging and a reliable stem stalk bundle release action without dragging,
The use of a member that releases the tip by rotating the tip support that supports the tip side allows the device to be more compact and reduces costs, and the release of centrifugal force due to the rotary type due to the action of the hook. Defects can be avoided and a stem-and-stem bundle collection and release device that operates better can be obtained.

According to the second aspect of the present invention, there is provided a stem and stem bundle collecting / discharging device which is adapted to a specification with a stem and stem bundle collecting / discharging device without a risk of losing the stock original paying member by mounting the height adjustable stem former payment member on the body. There is an advantage that both a state suitable for the standard specification without the stem and stem bundle collection and release device can be exhibited.

The collecting action posture in which the plate 22 receives the tip side of the stem stalk bundle with the inclined surface 22A facing the front (FIG. 2)
From the state shown in FIG.
It is amplified and interlocked so as to be in the release posture rotated in 0 degrees (the state shown in FIG. 3). That is, by rotating the tip receiving portion 16 using the manual operation force as a driving source, the three to four stem culm bundles placed and held on the stem culm bundle collecting mechanism 13 are directed to the lateral side of the body. The forcible release is performed by the backrest plate 22, and the rotatable backrest plate 22 and the operation handle 2
The forcible release mechanism 14 is constituted by a structure interlocked with 4.

Rear horizontal surface 22B of the backrest plate 22
Is formed in an arc shape centered on the vertical axis P in plan view, which is the vertical axis direction. That is, even if the backrest plate 22 rotates, the left edge 2
The left-right space between 2b and the leaning guide plate 29 of the fuselage is kept unchanged, and effectively restricts the stem-culm bundle from entering the left-right space.

A regulating rod 36 for preventing the stem and stalk bundles from entering between the leaning plate 22 and the leaning guide plate 29 of the leaning plate 22 is provided at the end of the leaning plate 22 at the body side, and a laterally outer end is formed at the time of collection. Receiving rods 28 for restricting the stem and stem bundles from falling laterally outward are provided respectively. Also, the bending rod 3 for restricting the stem stalk bundle from entering between the leaning guide plate 29 and the leaning plate 22.
It is equipped with 0, and by the bent part behind it,
Even when the backrest plate 22 is released, it is possible to restrict entry of the front end side while not hindering the front leaning guide operation on the backrest plate 22.

The above-mentioned regulating rod 36 can be pushed in the forced release direction by hooking the stem-and-stem bundle m in the leaning posture with the rotation of the spike receiving portion 16 on the body side end of the backrest plate 22. It also functions as an important member. That is, due to the centrifugal force generated when the backrest plate 22 rotates,
Even if the leaning stem stalk bundle slides on the inclined surface 22A, the regulating rod 36 positioned at the outermost periphery receives and supports the sliding stem stalk bundle m, and outputs the force to the right of the body. It functions so as to be surely transmitted, and prevents the stem and stalk bundle from falling down in front of the placing portion 15.
