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 lateral side edge of the tip end receiving portion on the body side is formed in an arc shape centered on the vertical axis when viewed in the vertical axis direction.

According to a second aspect of the present invention, in the first aspect, the tip receiving portion is formed on a surface.

[0007] A third invention is the first or second invention, wherein:
A tip restricting member extending from the fuselage, which is capable of restricting the tip side portion of the stem / culm bundle from entering between the tip receiving portion and the fuselage.

In a fourth aspect of the present invention, in the first to third aspects, a fall restricting member for restricting a stem and stalk bundle placed on the placing portion from falling to the side opposite to the side where the tip receiving portion exists is provided. Characterized by being provided in an elastically deformable state.

According to the structure of the first aspect, the bundle of stems and stems after binding is sequentially sent by the releasing action of the binding 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.

[0010] Since the tip receiving portion for supporting and supporting the tip side portion is rotated and forcibly released,
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, since the lateral edge of the tip receiving portion on the body side is formed in an arc shape centered on the vertical axis when viewed in the vertical axis direction, the tip receiving portion is rotated by the discharging operation. Also, it is possible to prevent the gap between the tip receiving portion and the body from changing, and to prevent the stem and stalk bundle from entering between the tip member and the body regardless of whether the forced release mechanism is operated or not. become. In addition, even if the next stem / bundle bundle is sent out from the tying device while the tip receiving portion is being released from the collecting action posture, the stem / bundle bundle is laid horizontally along the arc-shaped lateral edge of the tip receiving portion. It is guided to move, and can be transferred to the receiver. That is, even if the spike receiving portion has a rotating structure, the stem and stalk bundle can be sent to the mounting portion without stagnation, and the collection and release of the stem and stalk bundle can be performed continuously.

According to the second aspect of the present invention, since the tip receiving portion is formed on the surface, it is possible to smoothly guide the transfer while supporting the tip side of the stem stalk bundle in a wide area softly and without the catch. As a result, accidental shedding during collection can be avoided.

According to the third aspect of the present invention, the tip restricting member capable of restricting the tip side portion of the stem-and-culm bundle from entering between the tip receiving portion and the body is provided not by the tip receiving portion which is a moving member but by the body. Since it is extended from, for example, by disposing the tip restricting member above or below the tip receiving part, and both can be arranged so that they wrap laterally in plan view,
It is also possible to substantially eliminate the gap between the tip receiving portion and the body, and it is possible to obtain an effective entry preventing action.

According to the fourth aspect of the present invention, since the stalk and stalk bundle placed on the placing portion is provided with the fall-down regulating member for regulating the fall of the bundle to the side opposite to the side where the tip receiving portion exists, the unevenness of the ground is provided. Even if the stem-and-culm bundle is swung back and forth due to running, unevenness, or running vibration, etc. and tilts to the opposite side to the tip receiving part, the tip side part is regulated by the regulating member, and it falls forward or backward and is placed. It is possible to avoid falling from the part to the ground.

Since the restricting member is provided in such a manner that it can be elastically deformed in the front-rear direction, the stem-culm bundle released from the tying device can be moved backward or forward along the spike-receiving portion. When the number of stem stalk bundles collected at the placement part increases and the front-rear spacing between the spike receiving part and the regulating member becomes insufficient while guiding so that it falls down, the regulating member is elastically moved forward or backward. It is deformed and its front-back distance is widened, so that a predetermined number of stem-and-stem bundles can be collected without clogging.

[Effect] In the mowing and binding machine according to any one of claims 1 to 4, the stem and stalk bundle collecting mechanism for placing and collecting the stem and stalk bundle and the forced release mechanism for forcibly releasing the stem and stalk bundle are provided. By adoption, a member capable of reliably collecting the stem and stem bundles without clogging of stems and releasing the stem and stem bundles reliably without dragging, and releasing the stem by rotating the tip receiving device that leans and supports the tip side. The combined use makes it possible to reduce the size and cost of the device.Furthermore, even when the release operation is performed, the stalk stalk bundle collection mechanism can collect the stalk stalk bundle without any inconvenience, and a more efficient stalk stalk bundle collection and release device. Obtained.

In the stem-and-culm bundle collecting and releasing apparatus according to the second aspect, the stem-tip receiving portion has a surface, and thus there is an advantage that the stem and stem bundle can be collected smoothly without fear of shedding.

In the stem-and-culm bundle collecting and releasing apparatus according to the third aspect of the present invention, a simple modification such that the spike restricting member is attached to the fuselage allows the stem to enter into the gap between the spike receiving portion and the fuselage regardless of the release operation. There is an advantage that culm bundle entry can be effectively prevented.

In the stem-and-culm-bundle collecting and releasing device according to the fourth aspect of the present invention, by providing the fall-restricting member on the side opposite to the ear tip receiving part, an effective stem-and-culm bundle guiding action can be obtained at the initial stage of collection by the stem and culm bundle collecting mechanism. In addition, there is an advantage that a secure placement and holding action of the collected stem and stem bundle at the end of collection can be obtained.
