Description

[Detailed Description of the Invention] This invention relates to a two-bundle discharging device for discharging grain culms after cutting and binding into two bundles at a time to the outside of the machine in a binder.

Conventionally, as the aircraft advanced, the grain culms were raised at the front raising part, and the clipper-type cutting blades installed at the rear lower part of the grain culms were used to cut them, and the grain was moved to the side of the aircraft using a carrier and installed at the lower part. A binder is known in which grain culms are bound at a binding part and immediately discharged one bundle at a time from a discharge arm to the outside of the machine.

By the way, the bundles released at intervals in this way are scattered in the field, one bundle at a time, so there is a drawback that it takes time and effort to collect them.

In order to eliminate this drawback, for example, on the side of the machine,
Binders equipped with a shutter that collects a certain number of grain culm bundles and releases them all at once are also known, but these are driven by power from an engine and are mechanically complex and expensive. There were some shortcomings.

Therefore, in order to deal with these problems, this invention does not require a special drive mechanism from the engine.
It is an object of the present invention to provide a binder two-bundle discharge device that discharges grain culms in two bundles at a time.

Examples of this invention will be described below with reference to the drawings.

1 and 2 are front views of a binder equipped with this invention, a schematic side view of the binder, and FIG. 3 is an enlarged view of the two-bundle discharge device, and FIGS. 4a and 4b are A-A in FIG. 3. FIG.

The main parts of the two-bundle discharge device of this invention are comprised of a shutter 1, a control plate 4, a control fixing pin 6, etc.

The shutter 1 is made of a dogleg-shaped plate material, and a support plate 2 is formed on the side of the release arm 12 of a normal binder, and is formed to protrude horizontally from an appropriate position on the machine body toward the outside.
, in a receiving position on a horizontal plane (see Figures 3 and 5).
It is pivoted by a connecting pin 3 so as to be rotatable between the position and the discharge position (see Fig. 5).

A spring 7 is attached between the shutter 1 and the support plate 2 to bias the shutter 1 counterclockwise (towards the inside of the machine), and a stopper 15 fixed to the support plate 2 causes the shutter 1 to rotate counterclockwise. Its movement is regulated, and when it is in that position, it is in a receiving posture in which it receives the emitted bundle from the emitting arm 12.

One end of the control plate 4 is rotatably pivoted near the bent portion of the shutter 1 with a connecting pin 5, and a spring 8 is installed between the shutter 1 and the regulating plate 4 to bias the control plate 4 rearward. It has been intervened.

Opposite side of the shaft attachment part of control plate 4 (free end side)
is formed with a control portion 4a that is controlled by engaging with a control fixing pin 6 protruding from the support plate 2, and the movement of the control plate 4 and the movement of the shutter 1 are controlled via the pin 5. ing.

First, a fixing pin 6 is attached to this control part 4a.
a locking protrusion 4 that is locked to restrict rotation of the control plate 4 and maintain the receiving posture of the shutter 1;
b, an inclined guide part 4c that absorbs the impact force of the first emitted bundle, and a stop notch part 4d that stops and receives it;
Fitting grooves 4e and 2 are fitted by the force of the spring 8 after absorption.
Shutter 1 is activated again due to the impact force caused by the release of the bundled eyes.
Slide guide groove 4 that pushes and guides the two bundles to the release position.
f, guiding release recess 4g for sliding the fixing pin 6 under the control plate 4 to release the engagement;
Guide bending part 4 that returns to the original receiving posture with 8 forces
formed from h.

Note that it is desirable to use a spring material for the control plate 4.

From the outer side of the lower part of the bundling part 13 to the lower part of the shutter 1, a grain culm bundle holder 11 is formed to protrude from the machine body, and above the conveyor plate 14 and on the side of the middle part, there is an auxiliary conveyor plate following it if necessary. 9 is provided, and several soft springs 10 are provided at its outer end facing diagonally forward.

This invention consists of the above-mentioned structure, and its operation procedure will be explained with reference to FIGS.

First, when the grain bundles bound by the binding part 13 as in the conventional manner are discharged by the discharge arm 12, they hit the shutter 1 in the above-mentioned receiving attitude and push the shutter 1 outward.

Then, since the control plate 4 is biased in the counterclockwise direction by the spring 8 via the pin 5, the fixing pin 6 passes from the locking protrusion 4b to the inclined guiding part 4c and is stopped at the stop notch 4d. 5), the shutter does not open any further, and therefore the first emitted bundle remains inside the shutter 1.

When the impact force of this emitted bundle is absorbed, this emitted bundle does not push the shutter, and the force of the spring 7 guides the fixing pin 6 to the fitting groove 4e (see Fig. 5), and the shutter 1 is slightly returned. .

At this time, the lower part of the grain bundle rests on the pedestal 11 and does not fall, and the upper part is supported by leaning against the shutter 1 or by the auxiliary conveyance plate 9 and soft spring 10 provided as necessary. , it may be stably supported without falling backward or forward.

Further, the height of the shutter 1 must be set so that when the emitted bundle hits the shutter 1, it does not fall over and remains inside the shutter.

Next, when the second bundle of grain culms is released and the shutter 1 is pressed, the control plate 4 is urged counterclockwise by the spring 8, and the fixing pin 6 is controlled via the slide guide groove 4f and the guide release recess 4g. The plate 4 is pushed up and the shutter 1 is opened (see FIG. 5), and two bundles of grain culms are released simultaneously.

When the two bundles of grain culm are released, the fixing pin 6 passes through the guiding bending part 4h due to the force of the spring 7.
(See FIG. 5), the shutter stops when it hits the protrusion 15 and returns to its original receiving position.

As described above, in the binder reaping according to this invention, since the grain culm bundles are released in groups of two, the subsequent collection work becomes easier and the time can be shortened.

In addition, mechanically, the shutter is opened and closed using the energy of the released grain culm bundle, and there is no need to provide a special drive mechanism from the engine, making it simple and advantageous in terms of weight and cost. In addition, since this is done automatically, the operator does not need to perform any operations and can concentrate on operating the machine.
Various practical implementation effects can be expected.
