On the outside of the leaning guide plate, the ear side receiver,
The bundle collecting device in the binding machine is supported in such a manner that it is supported in a receiving posture for receiving the ear side of the bundle discharged from the bundling device and a releasing posture in which the bundle is raised and rotated, and the ear side receiver is received by a stopper. It has already been proposed in Japanese Laid-Open Patent Publication No. 62-30532.

(C) Problem to be Solved by the Invention The bundle collecting device in the known binding machine raises and releases the ear-side receiver when collecting a predetermined number of bundles, and immediately after that, the ear-side receiver , It rotates downward to receive the bundle discharged from the bundling device, but at that time, it collides with the stopper and is received, so it may rise due to its reaction.In such a case, the discharged bundle is collected. There was a case where it fell into the field without being caught.

(D) Means for Solving the Problems The present invention provides a leaning guide plate 4 at the rear of the cutting blade, a bundling device 10 at the side, and a bunch collecting device outside the bundling device. The stock receiver 13 is provided in the section, and the ear side receiver 15 is supported on the outside of the leaning guide plate so that the ear side of the bundle discharged from the bundling device is received and the release posture is rotated upward. In the binding machine in which the ear side receiver 15 is received by the stopper 68 provided on the machine body side in the receiving posture, the ear side receiver locking means 76 is provided in the vicinity of the stopper, and the locking means 76 is When the ear side receiver collides with the stopper and rises due to the recoil, the ear side receiver is locked to the machine side so as to prevent this, and the ear side receiver also drives the driver 70 to discharge the bundle. The ear-side receiver is configured to release the lock on the machine body side in conjunction with this when it is rotated upward. After releasing a predetermined number of bundles to the field and rotating downward and being received by the stopper, the ear side receiver tries to rise due to its reaction, but the locking means prevents this rise and the above-mentioned Solved the problem.

(E) Action The grain culm that stands up in the field is cut by a cutting blade, the cut grain culm is guided to a bundling device by a leaning guide plate, and the bunch bundled and released by the bundling device is a bundle collection device provided on the side part. Several bundles are collected by the strain receiver and the ear-side receiver.

When the number of collected bundles reaches a predetermined number, the ear side receivers rotate upward, so that the ear side falls to the field, and the stock base part slides down from the stock receivers.

Then, the ear side receiver is rotated downward until the next bundle is discharged from the binding device and is received in the receiving posture by the stopper.

At this time, the locking means prevents the ear-side receiver from moving upward due to the reaction, so that the bundle discharged next from the binding device can be reliably received.

(F) Embodiment An embodiment of the present invention and its related structure will be described with reference to the drawings. The binder is equipped with a cutting blade, a grass body, and a grain culm raising body 3, 3 on the front portion of a body 2 having wheels 1, 1. Then, the leaning guide plate 4 is provided at the rear part of the cutting blade, and the lateral carrier 5 having a large number of protrusions on the carrying surface
The engine 6 and the handle 7, the side clutch levers 8, 8 and the speed change lever 9 attached to the engine 6 are attached to the rear part of the cutting blade, and the side of the cutting blade is guided by the leaning guide plate 4 and the lateral carrier 5. A binding device 10 for binding and discharging the transported grain culms.
Is provided.

In addition, on the outer lower part of the binding device 10 and the leaning guide plate 4, a stock holder 13 detachably attached by a supporting shaft 11 in the front-rear direction and a hanging rod 12 hanging from the upper part of the grain culm raising body 3, and an upper part Frame
14a is provided with a bundle collecting device composed of a spike-side receiving member 15 pivotally supported by a horizontal shaft 14 so as to be vertically rotatable, and the grain culm is raised by the grain culm raising bodies 3 and cut by the cutting blade. Is conveyed to the side of the machine by the lateral conveyance body 5 while leaning against the leaning guide plate 4, and the packer of the bundling device 10 scrapes the grain culms that have been cut and conveyed to the bundling portion to condense them, and the bundling amount is a predetermined amount. When the door is detected and actuated, the needle wraps the cord like the conventional one, and the knot 20 composed of the building and the holder is knotted,
The discharge arm 21 discharges the bound bundle sideways, the root of the stock rests on the stock receiver 13, the ear side leans and projects outward from the guide plate 4, and inside the ear side receiver 15. It is suspended and supported by a flow guide 4a made of a flexible plate, and on the outer side, it extends from the upper part of the grain culm raising body 3 to the frame body 14a and the outer side of the ear side receiving body 15 is bypassed as shown in FIG. It is guided by the frame 22 that also serves as a guide and a guard, and is received by the ear side receiving body 15.

At that time, the bundle counting mechanism 23 provided above the packer and the needle of the binding device 10 inputs a release signal to the drive clutch 26 via the wire 25 when counting a predetermined number of bundles, and the drive clutch 26 drives the power of the axle. As a result, the receiver driving mechanism 28 is operated via the wire 27, so that the ear-side receiver 15 tilts upward, and the collected bundle is discharged in a state gathered in the field.

Next, each device will be described.

(I) Bundle Counting Mechanism The bundle counting mechanism 23 uses a drive gear 31 mounted on the needle shaft 30 of the binding device 10 as a drive source, and the counter case 32 has a gear 33 meshing with the drive gear 31 and a smaller diameter than that. The first shaft 35 that rotatably supports the small gear 34 as one body
And a second shaft fixed to an arm 37 having a pin 36 at the tip and the gear 39 having a pin 38 while meshing with the small gear 34.
40 and an output shaft 42 having an arm 41 fixed to the pin 38 of the gear 39 and fixed to the pin 38 are supported.
The boss 45 with the arms 43 and 44 extending to the left and right is rotatably mounted, and the output arm 46 is fixed to the upper end.
The other end of the wire 25 is connected to the tip end of 46, and the boss 45
The other end of a return wire 48 described later is connected to the one arm 43.

Then, every time the binding device 10 binds and discharges the bundle, the drive gear
The gear 31 rotates once, so that the gear 39 and the second shaft 40 rotate through the large and small gears 33 and 34 in the clockwise direction at a constant angle (1/5 rotation when collecting 5 bundles). When the second shaft 40 makes one rotation in this manner, the arms 41 and 44 are pushed by the pins 38 and 36 with a timing shift, so that the actuating shaft 42 rotates a predetermined angle and then returns and rotates.

Since the drive clutch 26 has the same structure as the known one, the description thereof will be omitted.

(II) Receptor Drive Mechanism FIGS. 1 to 5 show a receiver drive mechanism 28 of the ear side receiver 15. The ear side receiver 15 includes a receiving portion 15a on the gutter and an arm portion 15b. The boss is rotatably supported by the horizontal shaft 14 projecting from the frame 14a, and the receiver driving mechanism 28 has an arm 15b.
A control pin 66 protruding from the control shaft, stopper pins 67, 68 fixed to the mounting plate 65 integrated with the horizontal shaft 14 to receive the control pin 66 at the upper limit position and the lower limit position, and the base portion on the horizontal shaft 14. A driver 70 that is rotatably supported and connects the end of the wire 27 from the drive clutch 26, and an output arm of the bundle counting mechanism 23 that is rotatably supported at the lower part by a mounting plate 65.
It is composed of a stopper lever 71 having a stepped portion 71a for connecting the return wire 48 from 46, and a locking means 76 in which an intermediate bent portion is pivotally supported by a fulcrum pin 75,
The locking means 76 is V-shaped and has the control pin at one end.
It has a hook 79 for engaging and disengaging with respect to 66, and a driver 70 at the other end.
A receiving pin 78 that abuts with is projectingly provided, and the pivot portion is provided with a winding spring 77 for urging the locking means 76 so that the hook 79 thereof is disengaged from the control pin 66.

Then, while collecting the bundle, the ear side receiver 15 and the receiver drive mechanism 28 are in the state shown in FIG. 2, and a predetermined number of bundles are collected, and the pin 38 of the bundle counting mechanism 23 is an arm. Since 41 is pushed to rotate the operating shaft 42 and the output arm 46, the wire
25 is pulled and detection is activated, which causes the drive clutch 26
Is activated, the wire 27 pulls the driver 70 to pull the control pin 66.
The ear-side receiver 15 is rotated upward until it contacts the upper stopper pin 67, so that the collected bundles are discharged all at once in the field. In this case, when the driver 70 rotates, the locking means 76 is hooked by the winding spring 77.
Since the 79 disengages from the rotation trajectory of the control pin 66, the ear side receiver
The 15 can be freely raised and rotated.

At that time, since the wire 27 pulls the ear side receiver 15 until it abuts on the upper stopper pin 67 as shown in FIG. 3, and then relaxes, the driver 70 is provided between the driver 70 and the mounting plate 65. It is rotated downward by the winding spring 70a, and the ear side receiver 15
Is rotated downward by its own weight, but the stopper lever 71 is urged to rotate clockwise by the winding spring 72 and enters into the rotation locus of the control pin 66. Therefore, as shown in FIG. The part 71a receives the control pin 66 to receive the ear-side receiver 1
Maintains a release position of 5.

Next, since the pin 36 of the second shaft 40 of the bundle counting mechanism 23 pushes the arm 44 to rotate the boss 45, the arm 43 pulls the return wire 48, so that the stopper lever 71 rotates counterclockwise. , The step 71a comes off the control pin 66,
The ear side receiver 15 descends due to its own weight, and the control pin 66 is received by the lower stopper pin 68 to be in the receiving posture.

In that case, when the control pin 66 descends, the control pin 66 descends while pushing the hook 79 facing the rotation trajectory out of the trajectory against the winding spring 70a, and further, the control pin 66 pushes out the hook 79 and passes. Then, the driver 70 becomes a control pin.
Since the receiving pin 78 is pushed by the abutment of 66 or the urging force of the winding spring 70a to rotate the locking means 76 clockwise in the drawing, the hook 79 thereof engages with the control pin 66, and the control pin Even if 66 hits the stopper pin 68 and receives a recoil, the ear-side receiver 15 does not rotate upward,
As a result, the ear side of the bundle to be released next is not caught and missed.

Further, the stopper lever 71 returns to the receiving posture by the action of the winding spring 72.

(G) Effect of the Invention According to the present invention, the leaning guide plate 4 is provided at the rear part of the cutting blade, the bundling device 10 is provided at the side, the bundle collecting device is provided outside the bundling device 10, and the stock receiving device is provided at the side of the bundling device. The body 13 is provided, and the ear side receiving body 15 is supported on the outside of the leaning guide plate so as to have a receiving posture for receiving the ear side of the bundle discharged from the bundling device and a raising posture that is rotated upward. In the binding machine in which the receiving body 15 is received by the stopper 68 provided on the machine body side in the receiving posture, locking means 76 of the ear side receiving body is provided in the vicinity of the stopper, and the locking means 76 is the ear side receiving means. When the body collides with the stopper and rises due to the reaction, the ear side receiver is locked to the machine side to prevent this, and the ear side receiver is raised and rotated by the driver 70 to discharge the bundle. It is configured to release the lock on the machine side in conjunction with this, so that the bundle collection device collects a predetermined number of bundles. Then, the ear-side receiver 15 moves up by the driver 70 and can discharge the collected bundle all at once to the field, but after the releasing operation, the ear-side receiver 15 descends due to its own weight. , When the stopper 68 receives it, the locking means 76 of the ear side receiver prevents the ear side receiver from rising due to the reaction, and locks the ear side receiver 15 to the machine body side. Therefore, the ear-side receiver 15 does not rotate upward, whereby the bundle to be discharged next from the binding device can be reliably received and collected. In addition, the ear-side receiver is a driver for discharging the bundle.
Since the locking means 76 interlocks with this and lifts the locking on the machine body when it is rotated upward by the 70, the lifting operation of the ear side receiving body 15 for discharging the bundle can be performed without trouble.
