A bundle collecting device for a binding machine has already been proposed in Japanese Utility Model Laid-Open No. 62-30532.

(C) Problem to be Solved by the Invention In the bundle collecting device in the known binding machine, a bundle counting mechanism for detecting collection of a predetermined number of bundles measures the number of bundles discharged by the binding device by a ratchet mechanism. However, this method becomes costly because reliable operation cannot be obtained unless the processing accuracy of the ratchet gear feed mechanism is increased, and in a reaper binding machine that works in a field with a lot of dust and mud, Since the bundling device and the bundle counting mechanism operate near the ground, the dust and the like may adhere to the device, resulting in uncertain operation.

(D) Means for Solving the Problems The present invention provides a bundling device on the side of a cutting blade, a bunch collecting device on the outside thereof, and a stock receiver on the side of the bundling device, and behind it. On the upper part, an ear side receiver that receives the ear side of the bundle discharged from the bundling device is supported rotatably up and down, and the number of bundles discharged by bundling is counted by the bundle counting mechanism and the count number becomes a predetermined number. In this case, in the cutting and bundling machine in which the ear side receiver is rotated upward to be in the discharging posture, the drive source of the bundle counting mechanism is a drive attached to a shaft that rotates when one rotation clutch of the binding device is activated. The output shaft of the bundle counting mechanism without gears is configured to be decelerated according to the number of bundles collected at one time by a plurality of reduction gears housed in a gear case.

The sliding sliding drive includes a discharging sliding passive body that is mounted in a shifted manner and is interlocked with a clutch of a drive system that raises the ear side receiving body, and a returning sliding passive body that is linked to a return system of the receiving body drive mechanism. The ear-side receiver is configured to return to the receiving position after the discharging operation by intruding into the rotation locus of the body and the return sliding driving body, so that the ear-side receiver reliably operates even in a field with a lot of straw waste, dirt, or dust. In addition, the above-mentioned problems have been solved by making it possible to obtain inexpensively with simple processing.

(E) Action The grain culm that stands up in the field is cut by a cutting blade, and the cut grain culm is bound and discharged by the side bundling device. Several bundles are collected depending on the body.

During such bundle collection, the output shaft of the bundle counting mechanism is rotatably driven via a reduction gear by a shaft that rotates intermittently with one rotation clutch of the binding device engaged. When the rotation number is the same as the number of bundles to be collected, the output shaft makes one rotation and the detection signal is input to the ear side receiver, which causes the ear side receiver to rotate upward and collect the predetermined number of bundles collected at once. discharge.

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 way, the discharge sliding passive body 41 and the return driving passive body 43
However, since the discharge slide drive body 38 and the return slide body 36 are pushed at different timings, the output shaft 42 and the boss 45 rotate by a predetermined angle and then return and rotate by pulling the wires 25, 48, respectively.

Further, the transmission case 32 is housed in a narrow space in front of the wheel 1 in the middle of the machine body in the front-rear direction and in which a packer and a needle on one side of the binding device operate.

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 is composed of a gutter-shaped receiving portion 15a and an arm portion 15b, 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 portion 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 76 that engages and disengages 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 driving mechanism 28 are in the state shown in FIG. 4, a predetermined number of bundles are collected, and the pin 38 of the bundle counting mechanism 23 is armed. Since 41 is pushed to rotate the output shaft 42 and the output arm 46,
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.

At this time, the wire 27 pulls the ear-side receiver 15 until it abuts against the upper stopper pin 67 as shown in FIG. 3, and then relaxes, so that the driver 70 rotates downward and the ear-side receiver 15 self-weights. The stopper lever 71 is urged clockwise by the winding spring 72 to rotate downward due to the control pin 66.
As shown in FIG. 4, the stepped portion 71a receives the control pin 66 and maintains the release position of the ear-side receiver 15 as shown in FIG.

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.

At that time, the driver 70 pushes the receiving pin 78 to rotate the locking means 76 in the clockwise direction in the figure, so that the hook 79 thereof engages with the control pin 66, and the control pin 66 collides with the stopper pin 68. Therefore, the ear side receiver 15 does not rotate upward even if it receives a recoil, so that the ear side of the bundle to be discharged next is not mistakenly received.

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

(G) Effect of the Invention As described above, the present invention provides the binding device 10 on the side of the cutting blade,
A bunch collecting device is arranged on the outside of the bundling device, a stock receiver 13 is provided on the side of the bundling device 10, and an ear side receiver 15 that receives the bunch side of the bunch discharged from the bundling device 10 is provided at the upper rear portion thereof. Is supported rotatably up and down, and the number of bundles bundled and discharged is counted by a bundle counting mechanism, and when the count number reaches a predetermined number, the ear side receiver 15 is rotated upward to be in a discharge posture. In the cutting and binding machine, the drive source of the bundle counting mechanism 23 is a drive gear 31 attached to a shaft that rotates when one rotation clutch of the binding device enters and operates, and the output shaft of the bundle counting mechanism 23 is housed in a gear case. The speed reduction gear is configured to reduce the speed in accordance with the number of bundles collected at one time, and the final reduction shaft 40 of the speed reduction system configured by the reduction gear is attached to the discharge slide driving body 38 and the return slide. The drive unit 36 and the drive unit 36 are installed out of phase with each other to raise the ear side receiver 15. Of the discharge slide drive body 38 and the return slide drive body 36, and the release slide drive body 41 linked to the return system of the receiver drive mechanism 28. Since the ear-side receiver 15 is configured to return to the receiving position after being discharged into the locus after the discharging operation, the shaft rotating when the one-rotation clutch is engaged rotates a predetermined number of revolutions so that a predetermined number of bundles produces a bundle collecting device. Once collected, the discharge sliding drive 38 actuates the discharge sliding passive body 41, whereby the clutch is engaged and the ear side receiver 15 discharges, and then the return sliding drive 36 slides back. The passive body 43 is actuated, the ear side receiver 15 is returned and actuated,
During the cutting and bundling work performed while collecting such a bundle, a large amount of straw dust, dust and the like are generated in the vicinity of the bundling device 10 and the bundle counting mechanism, but the bundle counting mechanism works with simple gear meshing and pins and it. Since it is a combination with an arm, a signal that puts the ear-side receiver 15 into the emitting position and a signal that returns it to the receiving position by performing reliable bundle counting with very little influence of the straw waste, dust, etc. Can be transmitted accurately and for a long time.
