Description

[Detailed explanation of the invention] The invention is based on a deck that receives and supports the base of the bundle of bundled stems and rods that is intermittently released from the binding device to the outside of the machine body, and a working posture that leans and supports the tip side. A mechanism that engages and holds the receiver in a position where the stem rod bundle is received and supported is provided with a receiver that can be switched to a posture that swings downward by the weight of the leaning stem rod bundle and releases the stem rod bundle. The present invention also relates to a bundled stem rod collecting and discharging device in a reaping and tying machine, which is provided with a mechanism that automatically releases the mechanism when a set amount of stem rod bundles are received and supported by the receiver.

The tied stem stick collecting and discharging device in such a reaping and tying machine can release the tied stem stick bundles in multiple bundles at a time, so that the subsequent collection work of the released stem stick bundles can be streamlined. The receiver is configured to elastically swing and bias the receiver into a stem rod receiving and supporting posture, and after the ejection operation, the receiver automatically returns to its original position by the elastic biasing force. Ta. Therefore, even if a sufficient amount of stem rods are collected, especially if the stem length is short or lightweight, the weight of leaning against the receiver is small, so it is difficult to lean against the receiver. The weight of the stem tends to cause a situation in which it cannot be swung downwards, and if the elastic biasing force is reduced in order to avoid such a situation, the return operation of the receiver after the ejection action is uncertain. As a result, there is a problem in that the desired action of collecting the bundled stem bundles and rods cannot be performed.

In view of the above-mentioned circumstances, the present invention has an object to ensure that the collection and release of stem-rod bundles in appropriate amounts can be performed reliably, while also ensuring the automatic return action of the receiver.

The device for collecting and discharging tied stem rods in a reaping and tying machine according to the present invention is characterized in that, in the above-mentioned device, a drive mechanism is provided for forcibly returning the receiver to the receiving and supporting posture.

In other words, since it is configured to forcibly return automatically through the driving force after the release action, the resistance to the downward swinging of the receiver during the collection action is extremely small, and the leaning stem-rod bundle is Regardless of the fluctuations in weight, the downward swing due to the weight of the stem-rod bundle on which the receiver rests is always performed smoothly and reliably, and the collection and release of the stem-rod bundle in appropriate amounts can be performed reliably and stably. Moreover, after being released, it is now possible to use force to reliably and smoothly return the receiver to its original position.

Hereinafter, an embodiment of the present invention will be described based on the drawings. Fig. 1 shows a device 2 for raising planted grain rods into an upright position, and a device 2 for lifting planted grain rods into an upright position in front of a pair of left and right running wheels 1, 1. Clipper type reaping device 3 that cuts the stock base of the rod
And, the stock base transport device 4A and the ear tip transport device 4B transport the reaped stalks to one side of the machine in a vertical position, and the transported stalks are transported for each fixed amount.
A tying device 5 for tying and releasing the tying to the outside of the aircraft side is provided, and a driving unit 6 and a control handle 7 are provided at the rear of the pair of wheels 1, and a tying device 5 is provided on the side of the tying device 5. This walking type reaping and tying machine is provided with a bundled stalk collecting and discharging device 8 for collecting and discharging a set number of bundled stalks and rods intermittently discharged from a binding device 5 on the lateral outside of the machine body.

FIG. 2 and FIG. 3 show the bundled stem rod collecting and discharging device 8, which moves the base of the bundle of released stem rods backward as a part of it comes into contact with the stump A as the aircraft advances. The deck 9 that receives and supports the deck in a slidable state is positioned in a backward downward tilting position, and the tip side of the ejecting stalk bundle is tilted laterally outward, and the deck 9 is slid backward by its weight. It is supported by leaning against it while it is being moved, and the weight of the leaning stem-rod bundle causes it to swing downward around its front end horizontal axis X, thereby switching from the stem-rod receiving and supporting posture to the posture of releasing the stem-rod bundle. a mechanism 11 that includes a receiver 10 and engages and holds the receiver 10 in a stem-rod receiving and supporting posture; and when a set number of stem-rod bundles are received and supported by the receiver 10, A mechanism 12 that automatically releases and operates the mechanism 11; and a mechanism 13 that automatically returns the receiver 10 to the stem-rod-receiving and supporting posture after release.
and has.

The holding mechanism 11 includes an engagement member 16 that is detachably attached to the engagement piece 15 fixedly connected to the rotating shaft 14 of the receiver 10 on the fixed part side. A spring 17 is provided to move and bias the engaging piece 15 in the engaging direction, and the engaging piece 15
In addition, when the receiver 10 is in a posture other than the stem rod receiving support posture, a cam surface 18 is formed that abuts and holds the engaging member 16 in the non-engaging posture against the biasing force. Then, as the receiver 10 swings back to the stem-rod-receiving supporting posture, the engaging member 16 is automatically engaged with the locking piece 15, and the receiver 1 is automatically engaged with the locking piece 15.
0 is configured to be held in the stem-rod receiving and supporting posture.

The release mechanism 12 causes the arm 21, which is pressed by a cam 20 connected to the timing gear 19 and swings back and forth once, every time the knot drive timing gear 19 of the binding device 5 operates one rotation. The engaging member 16 is provided concentrically with the swinging member 23 that interlocks with the rod 22, and the swinging arm 21 is provided with a locking member that can be freely engaged with and disengaged from the swinging member 23 by swinging, and is in an engaged state. A pawl 24 is attached to disengage and swing the swing member 23 as the swing arm 21 swings back and forth, and when the swing arm 21 swings a set number of times. Only, a regulating mechanism is provided for engaging the pawl 24 with the swinging member 23, and the engaging member 16 is released each time a set number of stem-rod bundles are released.

The above-mentioned regulation mechanism is provided with a second pawl 25 that swings together with the pawl 24, and this second pawl 25
The rotating body 26 is engaged with the outer circumferential surface of the swinging member 23 and rotates by a fixed pitch in one direction each time the swinging arm 21 swings back and forth.
The second
Among the three engaging recesses for the pawl 25, the ones a located apart from each other by a set number of pitches are configured to engage the second pawl 25 deeply so that the pawl 24 engages with the swinging member 23; , what remains b..., nail 24
The second
The claw 25 is configured to engage shallowly. In addition, this regulation mechanism has a plurality of rotating bodies 26 arranged in parallel with different pitch numbers of the engagement recesses a which deeply engage the second pawl 25, and
The claws 25 are selectively engaged with these rotary bodies 26, and the number of binding operations for disengaging the engagement member 16, that is, the number of bundles to be collected, can be set and changed. 26' is a leaf spring for preventing the rotating body 26 from reversing.

The automatic return mechanism 13 includes a member 27 that is pressed by the cam 20 and swings out of the cam action range as the timing gear 19 rotates, and also includes a member 27 that swings out of the cam action range. 14, by the pressing and swinging of the member 27, the receiver 10 swings back to the stem rod receiving and supporting position, and by the downward swinging of the receiver 10, the member 27
