Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a system in which a one-turn clutch of a drive system for culm bundling and discharge is activated when the door to the bundling culm discharge port is swung by a pressing force greater than the setting of the bundling culm. The present invention relates to an agricultural binding machine that is provided with a spring that is interlocked with an operating member of the clutch to maintain the door in the closed position and maintain the clutch disengaged position of the operating member.

In the above agricultural binding machine, immediately after the door returns to the closed position,
As a reaction to the closing force, the door may rebound slightly to the open side against the spring that maintains the closed position, and as a result, the clutch that should have been disengaged may be engaged again. In order to prevent the above-mentioned empty binding, so-called empty binding is sometimes performed.In order to prevent the above-mentioned empty binding, a friction mechanism is conventionally provided which applies a predetermined resistance to the opening and closing swing of the door, and the frictional resistance prevents the side door from rebounding. However, due to the large number of openings and closings of the door, the friction mechanism was subject to extremely high wear and tear, resulting in a lack of durability.Furthermore, friction resistance was set to prevent wear of the friction mechanism. 9. The readjustment operation to maintain the value is troublesome and the problem arises.

In view of the above-mentioned circumstances, an object of the present invention is to improve durability while reliably maintaining the prevention function by rationally improving the structure for preventing the door from rebounding to the opening side. Another advantage is that readjustment operations are not necessary.

A characteristic configuration of the present invention is that, in the above-mentioned agricultural binding machine h, a door rebound prevention spring F collar is synchronously displaced so as to act on the door immediately after the door swings to the closed position. It is provided so as to be freely displaceable between a working position and a non-working position, and its functions and effects are as follows.

In other words, when the stem culm is east, when it is tied, and when the tied stem culm is released, etc.
In a series of operating processes, the stopper is synchronously displaced between the operating position and the non-operating position with respect to the door operation so that it is located at the operating position immediately after the door returns to the closed position, and the normal opening/closing operation of the door is performed. The stopper effectively prevents the door from bouncing back immediately after it returns to the closed position, and by using the stopper, early damage due to wear that occurs with conventional structures is avoided. This greatly improves durability, and also greatly improves maintainability by eliminating readjustment operations during use by simply adjusting the phase of the stopper at the time of manufacture. I've come to the point where I can do it.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

Figure v, 1 shows a device that is installed on the threshing machine @ Ill and binds and discharges the scraped waste straw supplied by the clamping conveyor chain 1, and the waste straw from the conveyor chain (2) is transferred to the transfer system. Rotary packer (31, tie string (1) T-shaped to be scraped and conveyed to the collecting section (2) through the prisoner; needle (4) to be wound around the collecting section straw; knot building that connects the wound string (1) Various devices such as a chemical 1, a string holder 1111, and an arm (71) for discharging bundled stem culms are arranged above and below the converging part (8), and the converging part (Bl can be opened and closed freely with respect to its discharge port (C)). The door (81) is configured to also serve as the operation sensor of the clutch (91) that connects and disconnects the drive of the various devices, so that when the pressing force of the converging stem culm against the door area exceeds a set value, the door ($1 is Clutch (I)
The needle (4), the nodule structure 1, the holder 1, and the ejection arm 1 are activated at a predetermined timing.

As shown in Fig. 2, the clutch (91) has an operating position that interferes with the rotation locus of a protrusion C111 attached to a gear ring that is constantly driven and rotates, and a non-operating position that is retracted. The latch operated member a, which can freely change its swinging position, is attached to the front clutch cam a:4, which is rotatable around the same axis as the gear, with the latch operated member a being biased toward the operating position by the spring a4. The clutch operating member rJlil is held in a non-operating position against the operated member lI'At spring 04 by engaging the claw-shaped engaged member N (12a) formed on the operating member 11!l.
With this, when the operating member 01t is switched to the unlatching position, the shift latch cam fil is rotated integrally with the gear cry due to the locking action of the projection αl and the force of the operated member a, and the cam llj is The interlockingly connected needles (
4) At the end of one rotation of the cam a-, the operating member 01 is engaged with the locked part (12!L) so as to drive the various devices, and the operated member a'b is deactivated. By returning to the position and holding it, the rotation of the cam ti= is stopped and the needle (
4) It is configured to cut off power transmission to various devices.

In the figure, - is a stopper that allows the forward rotation of the cam a- by its elastic retraction action, and prevents the cam as from reversing by its abutting action against the cam IIs when the rotation of the cam a3 is stopped.

To configure the linked operation structure between the door (8) as the clutch operation sensor and the clutch ill, there is a support shaft lll.
The operating member is attached to the latch bracket (11η), which is rotatable around the same circumference, between a locking position and a non-locking position with respect to the locked portion (12a) K, and the clutch bracket 117) Spring I installed between
A roller is pivotally connected to the clutch bracket 071 in a state in which it is biased towards the locking action position, and is always pressed into contact with the outer circumferential surface of the clutch cam ring by the reaction force of the α-th spring. 17a) k installation.

The formed elongated hole (15a) is locked and connected to the bin (20a), so that when the waste straw is collected, the operating member α
The urging force of the biasing spring (1111) against the IK holds the door (8) in the i-closed position, and the door 181 swings open due to the pressing force of the collecting and discharging straw against the closing biasing force. , pin (20&) and long (15a)
The operation member (II) is connected to the locked part (12 &
), and the clutch (91t-manual seat) is operated.

Then, the roller (1) a is rotated by the rotation of the cam α.
Due to the rocking of the clutch bracket (IT) as the cam alK forms and enters the nine recess (13!L), the reaction force against the spring o1 of the clutch bracket F releases its stopping action. Then, the knot 1 of the door 181, which had been biased toward the closing side by the spring I, was moved to allow the door 181 to open to release the bundled straw, and the cam of the roller (1) &) was actuated in the opposite direction. One door (81t) is configured to close (7) as the vehicle climbs up to the outer circumference.

To describe the opening/closing structure of the door 1111 in more detail, a cam portion (20'b) t'' is integrally formed at the other end of the door arm and is provided with the same number of teeth as the gear so as to be in constant engagement with it. A stopper (■) that prevents the door (III) from opening by contact with the cam part (201) of the door arm is placed on the outer circumferential edge of the idler gear 1211, and is moved to the locking position as the idler gear rotates. The stopper is installed so that it can be rotated between the non-operating position and the non-operating position, and by adjusting the rotational phase between the stopper ■ and the cam driving protrusion 01), the stopper returns to the operating position immediately after the door II!11 returns to the closed position. The mounting phase of the stopper is set so that the stopper is positioned at Doorha 8
The stopper opening is synchronized with one swing to prevent empty bundling caused by the Clara chain 191, which should be maintained in the cut state, being re-entered by the rebound operation of the door 18). It is configured as [$1].

In addition, please install the stopper to prevent the door from rebounding (81
Various improvements can be made to the specific interlocking structure for synchronized displacement with respect to the swing #.Also, instead of having the stopper = -■ act in contact with the door arm -, it may be possible to directly act on the door (1H). or a clutch operating member (IvIK activated, etc.) that is linked to the door (set).
Its direct acting targets can be changed in various ways.

The present invention is directed to an agricultural tying machine for electrical purposes such as removing waste straw and harvesting stems and culms.
