Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology belongs to the technical field of the structure of a device such as a reaper that completely supports a collected bundle with a crop support plate and processes it in the next stage.

Therefore, this invention eliminates gaps caused by vibrations, etc. in the focusing section where the front focusing dropper door can freely come into contact with and separate from the crop receiving plate provided at the rear of the focusing device of the reaper. This invention relates to a focusing dropper door structure, in particular, the dropper door abutting part on the outer side of the crop receiving plate has a stepped part, and the tip of the focusing dropper door is bent and comes into elastic contact with the stepped part so as to be releasable. This invention relates to a focusing dropper door structure for a reaper that supports a predetermined number of focused bundles and then releases them into the field.

<Prior Art> As is well known, a rice harvesting machine such as a harvester is generally configured to collect harvested crops into bundles of a predetermined thickness and release them into a field.

For example, as shown in FIG. 1, the binder 1 as a reaping machine is operated in the advancing direction by the handle 2, and the crop is harvested by the pre-processing section 3.
It is transported horizontally and bound by the binding machine 4, and the binding machine 4
The binding bundle is discharged into the slit part 8 between the inner and outer frames 6 and 7 provided in the convergence processing device 5 on the side of the stubble. The head side of the ears is attached to a focusing dropper door 11 fixed to a swinging shaft 10 extending horizontally on the binding machine 4 and a crop receiving plate 12 fixed to the inner and outer frames 6 and 7. Locks in a tilted position,
Due to the rotation of the swing shaft 10 that is intermittently linked to the bundling count by the bundling mechanism 4, the focusing dropper door 11 is separated from the contact portion of the crop receiving plate 12, and is intermittently opened and closed downward to form a predetermined number of bundling bundles 13. I try to release it into the field in an inverted position.

<Problem to be solved by the invention> However, the crops are tied together in a predetermined number of bundles 13, 13.
Crop receiving plate 12 and focusing drop pad door 1 until...
In step 1, the head side of the ear is locked in a tilted position, but by then, a gap is likely to be formed due to vibration etc. in the contact area between the crop receiving plate 12 and the focusing dropper door 11, and the head side of the ear etc. is scattered and the rice ears fall off. However, there were drawbacks such as problems such as binding in the mechanical parts and the like.

As a result, there were some problems that required extra labor for realignment.

To deal with this, there is a technology that attaches the crop receiving plate between the frame and the frame using long holes to absorb the gap formed by vibrations, etc., but this has the drawback that it is difficult to work on site and requires considerable heat to adjust. It was an inconvenience that required practice.

<Purpose of the invention> The purpose of this invention is to solve the problem of locking a predetermined number of focused bundles of a harvester to a crop catch plate in a tilted position based on the above-mentioned conventional technology, and to By providing a stepped portion in the contact area of the drop pad door, and by bringing the focusing drop pad door into elastic contact with the stepped portion, it is possible to absorb the formation of gaps due to vibrations, etc., and to make it possible to lock the head of the ear in a tilted position on the crop receiving plate without spilling. It is an object of the present invention to provide an excellent focusing dropper door structure for a reaper, which is beneficial to the field of mechanical technology application in the agricultural industry.

<Means/effects for solving the problem> In accordance with the above-mentioned purpose, the configuration of this invention, which is summarized in the scope of the above-mentioned utility model registration claim, is to solve the above-mentioned problem. By making elastic contact with the step part on the outside of the crop receiving plate through the bent part, a closed space is always formed even when there is vibration, and the crop receiving plate is held without spilling or catching the head of the focused bundle. A technical measure has been taken in which the plate surface and focusing dropper door are opened and installed in a tilted position in an orderly manner in the field.

<Example> Next, an example of this invention will be described below based on the drawings from FIG. 2 onwards. Note that FIG. 1 will be referred to and the same parts will be described using the same reference numerals.

In the embodiment shown in FIG. 2, the convergence processing device 5' provided outside the binding machine 4 for the binder 1 constitutes the gist of this invention, and its inner and outer frames 6' and 7' are set at a set height above the ground. A crop receiving plate 12' curved upward and rearward is fixed to the rear end of the machine in a side-extending manner via bolts 14. A notch 15 as a stepped portion is formed at the outer end of 12', while a swing shaft 10 that rotates and swings intermittently traverses the inner and outer frames 6' and 7' at a set height above the ground.
The focusing dropper door 11' is fixed at its tip, and its tip is extended backward, and the bent convex part 16 at the tip of the focusing dropper door 11' is attached to the notch 15 of the crop receiving plate 12' so that it can be freely separated. It is attached via the elasticity of the dropper door 11' so that it can be engaged and opened and closed.

As shown in FIG. 3, the crop receiving plate 12' has holes 1 into which bolts 14, 14, . . . for attachment are inserted.
7, 17... are drilled.

In the above configuration, as the binder 1 advances and performs a predetermined harvesting operation on the grain culm rows, the bundles 13, 1 are harvested one after another and bound by the binding machine 4.
3... are discharged to the outer frame 7' side of the convergence processing device 5', locked and placed on the outer frame 7' in an upright position, and when the neck side is also discharged and aligned, the subsequent tied bundles 13 are discharged to form a predetermined bundle, the previously discharged tied bundle 13 is pushed out onto the slit 8 and transferred one after another in an upright position, and the base of the bundle is locked to the already stubbles 9, 9... in an upright position. The crops are conveyed relatively backward while maintaining the same, and are collected into a predetermined number of bundles up to the crop receiving plate 12'.

A notch 15 is provided on the outer side of the crop receiving plate 12', and the protruding end portion 16 of the focusing dropper door 11' is surely engaged in an elastic state to form a focusing closed space. Therefore, the first bundle to be discharged is 13.
It completely surrounds the neck side of the ear and maintains a focused state up to a predetermined number.

When a predetermined number of bundles 13... are bundled, the swing shaft 10 rotates to swing the bundle dropper door 11' downward, and the bundle groups 13, 13, . They are released onto the field in a laid-down position in an orderly arrangement, and then returned to the initial position, and this operation is repeated to continue the cutting and tying process.

It goes without saying that the embodiment of this invention is not limited to the above-mentioned embodiment, and various embodiments are possible, such as making the crop receiving plate a removable attachment type.

<Effects of the invention> As described above, according to this invention, a stepped portion is provided at the abutting portion of the focusing dropper door of the crop receiving plate of a focusing processing device such as a reaping machine, and the tip of the focusing dropper door is bent at the stepped portion. The convex part is in elastic contact and opens and closes intermittently downward when separated, so that the neck side of the bundle that is discharged from the binding machine and sent to the crop receiving plate of the convergence processing device is in contact with the crop receiving plate. An excellent effect is achieved in that it is prevented from being caught between the abutting portions of the plate and the focusing dropper door, or from spilling.

Moreover, since the structure is simply to bring the focusing drop pad door into elastic contact with the stepped part of the crop receiving plate, repeated work is possible without adjustment.The crop receiving plate is curved upward and backward, so It also has the effect that the neck side is completely held and the grain culm does not sag and can be placed in a tilted position even after being released.

Furthermore, since it is only necessary to provide a stepped portion on the crop receiving plate, it is easy to perform, and it has the advantage of being easy to manufacture at low cost.
