Description

[Detailed description of the invention] This invention is a binder that can bind and release harvested grain culms in fixed amounts at a time.This invention is based on two bundles of bound grain culms that can be bundled together and released to one side of the aircraft. Relating to a release device.

As is well known, the binder moves while reaping a group of grain culms that are planted in multiple rows in the field, binds the harvested grain culms in a fixed amount, and releases the bundles one by one at appropriate intervals to one side of the machine. For some reason, the post-work to collect the emitted bundles became a labor-intensive task.

Therefore, this invention takes out a PTO shaft that is decelerated by 1/2 of the knot shaft that drives the discharge arm, and uses this PTO shaft to create a binder that discharges the bound grain culm bundles in groups of two. A two-bundle discharge device is provided to address the above-mentioned problems.

In other words, with the above reduction ratio, the PTO shaft rotates once for every two rotations of the nodulation shaft, and thereby, the grain culm is bound twice during two rotations of the nodulation shaft.
On the other hand, the shutter linked to the PTO shaft opens and closes once during one rotation of the PTO shaft, and immediately returns to the closed state after opening.

Of the two bundles of tied grain culm bundles that accompany the two rotations of the knotting shaft, the first one is held in a held state by the shutter, and the timing of the release of the next bundle is matched with the release of the next bundle by the PTO. 2 at a time in conjunction with one shutter opening/closing operation associated with one rotation of the shaft.
It allows for the release of bundles.

In addition, as mentioned above, this shutter immediately returns to its original state and remains closed at all times, except when it is being released, so it is able to receive the first bundle and simultaneously release the next bundle. This makes it possible to release two bundles at a time, and it is also possible to easily synchronize the timing of these release operations with the opening and closing of the shutter.

Hereinafter, specific embodiments of this invention will be described with reference to the drawings.

The binder includes a transmission box 2 that pivotally supports the wheels 1, 1;
It is formed by attaching a reaping binding section B to the front part of a drive section A that is composed of an engine, a control handle 4, a speed change operation device 5, and the like.

The reaping binding section B includes a grain culm pulling device 7 tilted from the front part of the reaping frame 6 toward the upper rear, and the reaping device at an appropriate position in the lower space connected to the pulling path 9 formed by this device 7. Along with installing 10 horizontally,
A cross-feeding passage 11 and a grain culm support guide plate 12 tilting backwards are installed on the rear side, and a binding case 13 having a generally L-shape in plan view is disposed at the end of the cross-feeding passage 11. A lateral feed passage 11 is connected to a lateral bundle discharging passage 14 provided in the lateral direction, and a binding device 15 supported and driven by a binding case 13 is installed so as to sandwich this bundle discharging passage 14.

The tying device 15 has a tying part 17 consisting of a knotter bill, a string holder, a discharging arm 16, a tying cover, etc. located at the front of the fuselage across the tying release passage 14, and a tying part 17 including a knotter bill, a string holder, a discharging arm 16, a knot cover, etc. on the rear side of this passage 14. position.

By the way, in the two-bundle discharge device according to this invention, the PTO shaft 23 is projected upward from the extension bundling case 13a by reducing the speed to 1/2 by the gears 21 and 22 from the middle part of the joint shaft 20 that drives the discharge arm 16 intermittently. ,
A traction body 24 having a traction pin 25 fixed to its upper surface is fixed to the protrusion, and one end of a crank 26 is rotatably supported above where it can come into contact with the pin 25.

Further, the end of the inner 28 of the operator 27 is pivotally connected to the other end of the crank 26 by a connecting pin 26a.
The outer 29 is attached to the extension binding case 23a, etc., and the operating tool 2 of the attachment part 30 is attached to the extension binding case 23a.
The PTO shaft 23 is fixed at a position where the axis position of the PTO shaft 23 is shifted upward by a required distance l from the line of action S of 7.

Then, move the tow pin 25 position to the PTO shaft 23.
The traction pin 25 is set at a position where it contacts the crank 26 between the shaft center and the fastening part 30 so that the crank 26 and the inner 28 that pulls it form a square shape (see Fig. 2), It controls the operation and timing of the discharge arm 16.

On the other hand, the outer 29 end of the extended end of the operating tool 27 is fixed to the extension binding case 13a, etc., the inner 28 end is attached with a spring 31 as an extension, and the other end of the spring 31 is attached to the extension binding case 13a. 13a
Pull it to secure it.

Therefore, the crank 26 is always urged toward the fastening portion 30, and the crank 26 is pushed by the traction pin 25 located at the solid line position as shown in FIG.
When the PTO shaft 23 is forcibly rotated half a turn to the position shown by the dashed line on the opposite side, the axis of the PTO shaft 23, which is the rotation fulcrum, is located above the line C connecting the connecting pin 26a and the fastening part 30 (on the line of action S side). Since the crank 26 is placed on the traction pin 25 without stopping,
It immediately rotates in the direction B and returns to the solid line position.

Next, a shutter 32 formed in an appropriate shape to receive the emitted bundle on the lower surface of the extension bundling case 13a near the attachment part of the inner 28 and the spring 31 is positioned outside so as to block the bundling release passage 14. The base part is pivoted 33 to the upper surface of the extension binding case 13a so that it can be opened and closed.In this case, the inner 28 and the spring 31 are arranged in a relationship so that the vicinity of the attachment part of the spring 31 is located at an appropriate position on the base side. The shutter 32 can be opened and closed by the movement of the shutter 32. For example, as shown in the embodiment, a fitting pin fixed to the inner 28 is slidably fitted into a long hole of the shutter 32.

This causes the crank 26 to move to the tow pin 25.
When it is forcibly towed and rotated, it can change between the receiving position and the emitting position of the emitted bundle.

In the embodiment, a shutter arm 32a having a roughly Z-shape in side view is pivoted at the base side 33, and a bundle receiving plate 32b is fixed to the bundle release passage 14 side of the shutter arm 32a.

Therefore, in Fig. 2, the towing pin 25 is now rotated from the solid line position in the direction A and
Crank 26 to the chain line position opposite to the shaft 23
When the shutter is forcibly rotated half a turn, a bundle of discharge arms is sent from the discharge arm 16 to the shutter 32 side, and at the same time, the spring 31 is pulled through the inner 28, and the shutter 32, which had been closed until then, is moved to the solid line position. Since it is opened to the position indicated by the chain line in the A' direction, the new emitted bundle is immediately released to one side of the fuselage together with the previously received single emitted bundle, resulting in so-called two-bundle release.

Then, the crank 26 that has been towed to this chain line position quickly moves to the fulcrum 23 as described above.
The shutter 32 is rotated back beyond this point, and the shutter 32 is moved in the ``low'' direction to return to the original receiving position, and waits for the next discharge by the discharge arm 16.

Next, the remaining towing pin 25 rotates half a turn in the direction B from the chain line position, and on the way to the solid line position,
The crank 26 that had been returned earlier is brought into contact again and towed to return to the initial state.

During this time, the ejection bundle emitted by the ejection arm 16 is transferred to the shutter 3, which has returned to the previous receiving posture.
2 blocks the discharge to the outside of the aircraft, and the bundle is received by the shutter 32.

Then, the tow pin 25 again moves half a turn in the A direction from the solid line position to the chain line position, and the two bundles are released as described above.

As is clear from the above explanation, according to this invention, the first emitted bundle is received with the shutter 32 in the closed receiving position, and the second emitted bundle is then transferred to the previous first bundle. Since the released bundles are combined with the released bundles and released into the field, it is easy to synchronize the timing of the release operation by the release arm 16 and the opening/closing of the shutter 32, and the released bundles released into the fields in two bundles are Since bundles can be collected one by one, the number of man-hours required for collection work can be reduced.
