Description

[Detailed description of the invention] This invention has a clipper-type cutting blade placed horizontally at the inner depth of a plurality of planted grain culm introduction paths, and the grain culms of each path are pulled rearward in front of this cutting blade. Thereafter, a rotary packer is installed to feed the grain to one side laterally, and an elastic guide rod that presses the introduced grain culm against each rotary packer is installed in a backward cantilevered manner in each route. A binding device equipped with a crank-type plucking packer that acts from the side is provided, and the plucking packer and a rotary plucking car on the terminal end side in the traverse feed direction are arranged opposite to each other across the traverse feed path, and The present invention relates to a binder in which a conveying cover is provided on the rotary packer on the upper side of the rotary packer in traversing, and the terminal end side of the cover extends to the vicinity of the action locus of the scraping packer.

The transport cover for the binder with the configuration described above is
After the grain culm introduced into the left introduction path is cut by the cutting blade, it is smoothly guided to the lateral feed path, and
In order to form this cross-feeding path, the rear surface of the cover is smooth and shaped to follow the cross-feeding path. The conveying cover extends to the right so that it acts as a weeding tool for pushing and separating the weeds, and so that the grain culms introduced into the right introduction path are smoothly introduced into the rotating weeder at the end of the lateral feed path. As shown in FIG.
The extending portion 30B of 0 is manufactured so that when the grain culm is introduced, the elastic guide rod 15 elastically swings and comes into contact with it. A space T is formed between the front of the action locus S of the raking packer 16 and the front of the extension portion 30B, and the reaped grain culm may enter this space. Since none of the conveying devices installed in the binder work, the grain culms that have entered are not only stagnant and difficult to be carried out, but also because the cutting blade 6 is located just below this space T. The raking packer also has the effect of pushing the grain culm forward slightly,
Once the grain culm has been cut, it falls in front of the cutting blade 6 and the root of the grain is cut off again, which causes the problem of uneven grain attachment when tying.

The present invention has been developed in view of the above-mentioned circumstances, and by rationally modifying the shape of the conveyor cover, the space is narrowed, thereby preventing the harvested grain culms from stagnation and the stock base being cut again. The purpose is to eliminate the occurrence of irregularities in grain deposits during bundling.

The present invention is characterized in that the terminal edge of the conveyor cover extension is configured in a shape that follows the rake packer action locus, and the elastic guide rod of the terminal rotary packer is formed at the front edge of the conveyor cover extension. at a point where the corner formed by the terminal edge of the conveyor cover extension and the front edge is provided near the intersection of the elastic guide rod in the received state and the rake packer locus. Its functions and effects are as follows.

In other words, by adopting the above structure, the space in which the grain culms stay is narrowed, so that the harvested grain culms do not stay in the middle of transportation, and the harvested grain culms fall in front of the cutting blade, causing the stock to be cut again. The unevenness of grain deposits at the time of bundling, which is caused by
This also improved the efficiency during threshing of the bundled grain culms.

Next, embodiments of the present invention will be described based on the drawings.

It is formed along the conveyance path B of the device 8. Further, the right side edge 9d of the tapered portion 9A is formed to widen rearward, and is continuous with the front side edge 9e of the extending portion 9B. Further, a terminal edge 9f is formed on the right side of the extending portion 9B,
This terminal edge 9f is molded and manufactured so as to coincide with a part of the working locus S of the raking packer 16, which will be described later, and the front edge 9e is formed so that the grain culm comes into contact with an elastic guide rod 15, which will be described later. so that when the guide rod 15 is elastically swung, the guide rod 15 is closely received.
It is manufactured in a shape that follows the shape of this guide rod 15. The corner formed by the front edge 9e and the terminal edge 9f is called 9C and is shaped into a very small arc.

Further, the conveyor cover 9 has three protrusions below it, and a rotary packer 1 that is driven and rotated around the vertical axis.
0, and rod-shaped guide members 11, 11 are provided on the upper and lower sides of this packer 10, which are bent and formed so as to prevent the reaped grain culm from being caught in the rotating shaft.

In addition, on the lower side of the conveyance path B across the planted grain culm introduction path _A2 on the right side from this packer 10,
Another packer 12 is equipped, and rod-shaped guide members 13, 13 are provided in the same manner as described above.

On the left branching rod 4, there is a plate-shaped elastic guide rod 14 in which a slit is formed in a fork shape from the approximate center to the tip to allow rotation of the rotary packer 10 at the center. The rod-shaped guide material 1

Further, as described above, the center branching rod 4 also has a plate-shaped elastic guide rod 15 with a fork-shaped slit formed from the approximate center to the tip to allow rotation of the guard car 12 on the right side of the fuselage. However, the rod-shaped guide material 13,1
It is bent into a substantially semicircular shape and is attached in a cantilevered manner so as to abut along the rear surface of 3.

Further, the conveying device 8 is for laterally conveying the harvested grain culm to the right side of the machine, and the transportation of the harvested grain culm is as follows:
It is set slightly downward to the right so that it runs along the rear edge 9b of the conveyance cover 9, and a crank-type scraper 16 that assists conveyance is driven along an action locus S on the lower side of this conveyance path. The binding device 7 is equipped with the transport cover 9, and as described above, the terminal edge 9f of the conveyance cover 9 is arranged so as to coincide with a part of the working locus S of the scraping packer 16 in a plan view. A rod-shaped blocking member 17 for preventing the reverse flow of the transported grain culm is attached to the body in a cantilevered manner so as to overlap this action locus S in a plan view, and a binding device 7 is installed on the lower side of the transport route. ing.

Next, the harvesting of the planted grain culms will be described in detail based on FIGS. 1 to 4.

The grain culm group introduced into the left planted grain culm introduction path _A1 is acted on by the front part of the conveyance cover 9, and
Further, almost at the same time as the guide rod 14 is pressed, it is raked by the rotary packer 10, and the base of the stock is cut by the cutting blade 6. Then, the group of grain culms from which the stock base has been cut is conveyed to the rear right side by the pack car 10, and is sent to the right side of the fuselage while pressing the elastic guide rod 14 and expanding the conveyance space.
When it reaches this location, it is further conveyed to the right of the machine body by the conveying force of the conveying device 8, and is carried into the binding device 7 by the scraping packer 16. At this time, the right planted grain culm introduction route A ₂
The grain culms from the culm are harvested at the base in the same manner as described above, and are introduced into the raking packer 16 while expanding the conveyance space by pressing the elastic guide rod 15. As described above, the swinging end that swings when pressed comes into contact with the lower bent surface of the front edge 9e of the conveyance cover 9, thereby being regulated, and furthermore, the elasticity of the swinging end is regulated. By the guide rod 15 coming into close contact with the contact surface of the front edge 9e, the scraping packer 1
6 prevents the grain culm group, which is slightly pushed forward, from moving forward.

Next, the group of grain culms introduced from the left and right planted grain culm introduction paths A ₁ and A ₂ , conveyed through the path B, and further introduced into the binding device 7 by the raking packer 16 are cut in a substantially upright posture. They continue to be introduced into the upper surface of the bundling deck 18 with the part facing downward until a certain amount is reached, and when this amount reaches a certain amount, they are tied with strings and released out of the aircraft, which will be described in detail below.

As shown in FIGS. 2 and 4, the binding device 7 is
The binding part 7a composed of a holder, a bill, etc., the scraping packer 16, and the revolving door 19, etc., which has a function of detecting the amount of grain culm introduced by this using pressure and releasing it using rotational force. The revolving door 19 is arranged in the direction R at an angle of 180 degrees.
The door members 20, 20 are rotated 180 degrees in phase so that the bundled grain culms can be released by rotating the door members 20, 20.
is attached to the rotating shaft 21, and this door member 20
is a member with an L-shaped cross section, and has a horizontal part 20 at the bottom.
a is also arranged such that the vertical portion 20b is located on the downstream side of rotation in the rotation direction R, and further,
At the upper end of this vertical portion 20b, receiving members 22, 22 made of synthetic resin and having a fan shape in plan view are fixed with bolts. This is because, as mentioned above, when the grain culms are bundled in an almost upright position and released, the release resistance is lower and better than when the grain culms are released while touching the aircraft, but on the other hand, the grains are This problem is eliminated by supporting the culms by the receiving members 22, 22, which tend to fall over, and the reason why the receiving members 22, 22 are made of synthetic resin is as follows. As described above, the rotating door 19 detects the amount of grain culm introduced by the pressure it receives, and when the pressure reaches a certain pressure or more, a one-turn clutch (not shown) interlocked with the rotating shaft 21 is activated. is operated, the binding section is activated, and immediately after this, the revolving door 19 rotates 180 degrees to release the bundled grain culm, so that the receiving member 2
2 and 22 are lightweight and made of synthetic resin, the rotational inertia is kept low, and after the clutch is operated and the bundled grain culm is released, the rotating door 19 is further moved by the rotational inertia. This is effective in preventing the bundling device 7 from being driven idly when the bundling device 7 is operated.
