Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a bundle collecting and discharging device for a reaping and tying machine that gathers and discharges bundles of grain culms that have been harvested and bound by the reaping and tying machine.

(b) Prior Art A bundle collection device for a reaping and tying machine that collects several bundles of harvested and tied grain culms and releases them into the field is already known. There are those that discharge the bundles by actuation, and those that count a predetermined number of bundles using a bundle counter and then operate the bundle collection device using power from an axle or the like.

(c) Problems to be solved by the invention The manual method of the known bundle collection device has a simple configuration and can be provided at low cost, but requires a large amount of operating force, making it difficult to continue working for a long time.
In addition, methods that use power from a bundle counter and wheels can easily perform the bundle release operation, but they are extremely costly and the weight of the machine is large, reducing workability in soft fields such as wet fields. .

Furthermore, since the upper receiver in the known bundle collection device was mounted on a shaft installed on the side of the machine in a backward tilted position, when the upper receiver turned downward to release the bundle, the upper receiver released the bundle. There were times when the bundle was caught.

(d) Means for solving the problems The present invention provides a reaping and tying machine in which a lateral conveyance receiver is provided at the rear of the cutting blade, and a tying device is arranged on the side of the reaping and tying machine.
A lower receiver is provided at the lower part of the bundle release side of the bundling device,
A horizontal upper receiver is provided above it near the rear,
Although the upper receiver can be obtained with a simple structure and at low cost by supporting the upper receiver so as to move forward and backward between the bundle receiving position protruding from the back of the horizontal conveying receiver and the evacuation release position, the upper receiver The above-mentioned problems have been solved by making the bundle discharge operation easy and by preventing the bundles on the field from getting caught when the bundles are discharged.

(e) Operation The grain culms cut by the cutting blade are transported horizontally to the binding device by the horizontal transport receiver and are bundled and released.

The stock base of the released bundle rests on the lower receiver, and the panicle side is received leaning against the upper receiver. When the desired number of bundles is collected, the upper receiver is transferred to the horizontal transport receiver. When the machine is retracted to the back of the machine, the collected bundles are released into the field in a tangled state.

At this time, since the upper receiver retracts into the back of the horizontal conveyance receiver, the upper receiver does not rotate downward and catch the discharged bundle when the bundle is released.

(F) Example An example of the present invention will be explained with reference to the drawings.
1 is a machine body having wheels 2, 2 and equipped with an engine 3 at the rear, and a reaping device consisting of grass cutting bodies 4, 4, grain culm pulling bodies 5, 5, cutting blades 6, etc. is attached to the front part. At the rear of the cutting blade 6, a backwardly inclined guide plate 7 is provided.

Further, a knot part 9 and a discharge arm 10 are provided at the front part of the culm collection part 8 on the sides of the cutting blade 6 and the guide plate 7,
A binding device 12 equipped with a packer 11 and a needle is attached to the rear part.

A lower receiver 13 that slides on the ground is removably attached to the outer lower part of the binding device 12,
The guide plate 7 has a cutout window 15 in the middle, and has a floating V-pulley 16 pivotally supported on the binding device 12 side at the back thereof, and a driving V-pulley 17 pivotally supported on the opposite side and driven by the reaping transmission case. V stretched between
A horizontal conveying body 18 made of a belt has a large number of protrusions 2.
0..., and these protrusions 20... project forward from the cutout window 15 to tie the harvested grain culms to the binding device 1.
The shaft 21 of the floating V pulley 16 is supported at its lower part by a bracket 22 integral with a support 19 erected from the body 1,
A friction ring 23 whose outer periphery is coated with rubber or the like is attached to the upper part so as to rotate together.

The upper receiver 25, which supports the ear side of the bundles to be released and collected, is made of an oblong member with a downward U-shaped cross section, and as shown in FIGS. 1, 4, and 5, It fits loosely into a pair of guide frames 26 and 27 so as to be able to move laterally, the inner guide frame 26 substantially allowing lateral movement and turning as shown in FIG. 4, and the outer guide frame 27 as shown in FIG. It is supported to allow lateral and longitudinal movement.

Furthermore, a presser body 28, which is connected to the front surface of the outer guide frame 27 and is made of an elastic plate having a convex portion at its tip, constantly presses the front surface of the upper receiver 25 to prevent friction as shown in FIG. It is in pressure contact with the ring 23,
The swinging arm 30, which is pivotally supported by the bracket 22, has a roller 31 rotatably supported at its front end, and is normally urged by a return spring 32 so that the roller 31 is separated from the upper receiver 25. The portion is connected via a wire 33 to a lever 35 provided on a handle 34.

Furthermore, as shown in FIG. 6, a detection switch 37 is provided at the return position of a member such as the needle 36 (or ejection arm 10, knot portion 8, etc.) that is activated each time the binding device 12 performs the binding operation. Connect switch 37 to engine flywheel magnet 3.
8. If it is inserted into a circuit having a counter 39, reset switch 40, alarm lamp (or alarm buzzer) 41, etc., the worker can perform a discharge operation in a timely manner by engagement without having to count the number of bundles to be collected. can.

In the above-mentioned reaping and binding device, the grain culm cut by the cutting blade 6 of the reaping device is conveyed sideways by the horizontal conveyor 18 while leaning against the guide plate 7, and the grain culm is scraped by the culm collection unit 8 by the packer 11. Concentrate and focus.

When the amount of collected culms reaches a predetermined amount, the needle and the knotting section 9 are operated to knot the culms, and the discharge arm 10 discharges the bundle.

At this time, the front side of the upper receiver 25 is pressed against the friction ring 23 by the presser body 28 and protrudes outward as shown by the solid line in FIG. It is received by the body 13, and the ear side is received in a posture leaning against the upper receiver 25.

When several bundles are focused in this way, the lever 35
When the end of the swinging arm 30 is pulled, the roller 31 pushes the middle part of the upper receiver 25 forward, so the upper receiver 25 is pressed against the rear surface of the friction ring 23, and the grain culm is traversed. Move in the opposite direction to guide plate 7.
The collected bundles are discharged into the field. When the release is complete,
When the lever 35 is released, the roller 31 is moved backward by the return spring 32, so the upper receiver 25 is pushed by the presser body 28, and its front side is pressed against the front surface of the friction ring 23, thereby automatically sending it outward. Then she gets into a bundle-receiving position.

Furthermore, if the upper receiver 25 becomes an obstacle when harvesting around the field, it can be stored on the back of the guide plate 7 by simply squeezing the lever 35, and the lower receiver 13 can also be removed if necessary. I can do it.

(g) Effects of the invention Since the present invention is configured as described above, when releasing the collected bundles, the bundles can be easily released by simply moving the upper receiver 25 in the horizontal direction in and out. It has a simple configuration and can be provided at low cost.

Furthermore, when the bundle is discharged, the upper receiver 25 retreats into the space at the back of the horizontal conveyance receiver and hooks the discharged bundle like a device that rotates around a support shaft in a backward tilted position. Moreover, there is no obstacle to the horizontal transportation of the harvested grain culm.
