Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a straw binding device that is further attached to the rear of the cutter device of a combine harvester.

(b) Prior Art A technology in which a straw binding device is attached to the rear of a cutter device of a combine harvester is known.

(c) Problems to be solved by the invention Traditionally, binding machines have been provided with binding machine covers, but since they were fixed with bolts, etc., it is difficult to remove straw from the binding machine or the cutter device in front of it. If the tying machine became clogged, the only way to do so was to get in from below and remove the jammed leaves in the cramped space, or to remove the entire tying machine.

In particular, when a binding device is installed at the rear of the cutter device and can be switched freely, there is a problem that if the cutter device is clogged with straw, it becomes difficult to remove the clogged straw because there is a binding section in front. It was hot.

In order to eliminate these problems, this invention has a structure in which the binding machine cover is easy to open with a pivot point at the rear, and an intake guide is also integrally provided on this binding machine cover, so that the binding machine cover can be opened at the same time. The intake guide is also removable.

Previously, even when the tying machine cover was opened, the intake guide protruding from the tying machine was still holding down the clogged waste straw, making it difficult to clean, but this has also been improved. .

(d) Means for solving the problems The problems to be solved by this invention are as described above.
Next, means for solving the problem will be explained.

A tying machine cover 10 that covers the upper part of the straw discharging passage of the straw tying machine is pivotally supported at the rear of the straw tying machine on a pivot support 17 that protrudes upward from the tying mechanism case 18 so as to be able to move up and down. , the binding machine cover 1
0 is supported by bendable opening/closing links 15a, 15b between the tubercle cover 19, and the intake guide 3 is fixed to the opening/closing link 15a, which is the one closer to the tubercle cover 19, of the opening/closing links 15a, 15b. It was established.

(e) Embodiment The problems to be solved by the present invention and the means for solving them are as described above.Next, the structure of the embodiment shown in the attached drawings will be explained.

FIG. 1 is an overall side view of a combine harvester equipped with a straw binding device.

A weed cutting board 1 is provided at the tip of a pulling device 2, and the root part of the grain culm is separated by the weeding board and guided to the pulling device. While being raked in by the raking device 6, it is cut with a cutting blade 7 and guided to the stock transport device 4. The stock transfer device 4 transfers it to the vertical transfer device 5, and then to the feed chain 9 of the threshing device 13. On the other hand, the tip portion is transferred from the raising device 2 to the upper conveying device 8, and from the upper conveying device 8, it is sent to the handling drum inlet of the threshing device 13. The grain culm threshed in the threshing device 13 becomes waste straw and is sent to the waste straw binding device of the present invention.

Figure 2 is a right side view of the straw binding device which is the main part of the present invention, with the binding machine cover 10 open, and Figure 3 is a drawing with the binding machine cover 10 closed. . 4 is a rear perspective view of the binding machine cover part, FIG. 5 is a bottom perspective view of the binding machine cover 10, FIG. 6 is a side view of the opening/closing link of the binding machine cover 10, and FIG. 7 is a front view of the binding machine cover 10. FIG. 8 is a rear view of the binding machine cover.

In FIGS. 2 and 3, a cutter device 31 is provided on the rear surface of the threshing device 13. The straw is sent to the cutter device 31 through the straw removal chain 21 of the threshing device 13.

A cutter opening/closing cover 30 is provided on the top surface of the cutter device 31, and when the cutter opening/closing cover 30 is closed as shown in 30' and the cutter inlet is closed and the cutter outlet is opened, the waste straw is directed to the tying machine. flows to In addition, the cutter opening/closing cover 30 is
0'', when the cutter outlet is closed and the cutter inlet is opened, the waste straw enters the cutter device 31.

Power is transmitted from the drive pulley 23 of the cutter device to the binding machine drive pulley 24 via the V-belt 22. The binding machine drive pulley 24 transmits power into the binding mission case 18. Lower covers 25 are provided on the left and right sides of the binding mission case 18.

The binding machine cover 10, which is the main part of the present invention, is supported by a pivot support 17 that projects upward from the binding mission case 18 so as to be vertically movable. The structure of the pivot body 17 and the binding machine cover 10 is shown in a perspective view from below in FIG. The pivot body 17 is configured in an L-shape, and the horizontal portion serves as a pivot shaft 17a.

In addition, the front of the binding machine cover 10 is an opening/closing link 15.
It is supported by a and 15b. Metal fittings 27, 27 for pivotally supporting the upper end of the opening/closing link 15b are fixedly protruded from the lower surface of the binding machine cover 10.

The structure of the opening/closing link is shown in detail in FIGS. 6 and 7. The opening/closing link has a bent structure in which 15a and 15b are pivoted at the center, and a spring 14 extending beyond the fulcrum is interposed in this bent part. The spring 1 extending beyond this fulcrum urges the binding machine cover 10 downward. When opened, if the center pivot point of the opening/closing link is crossed, the spring 14 acts in the opposite direction to maintain the open state.

Furthermore, intake guides 3a and 3b are fixedly installed on the lower side of the opening/closing links 15a and 15b to smoothly guide waste straw to the binding section.

Conventional intake guides protrude from the nodule cover 19 or its vicinity, like the guide rod 20 that protrudes forward from the nodule cover 19 in FIGS. 2 and 3. However, when the intake guide is taken out from the knot cover 19 etc. as in the past, the intake guide remains even when the binding machine cover is opened, and the straw is removed when the cutter device gets clogged or the inside of the binding machine gets clogged. It was getting in the way when it was being pulled out.

In this invention, the longer intake guide is provided on the side of the binding machine cover such as the opening/closing link, so that when the binding machine cover is opened to clear a blockage, the intake guide 3 is also opened as shown in Figure 2. . By leaving the intake guide near the knot cover 19 as a short guide rod 20, the straw removal can be smoothly guided as before.

Furthermore, even when the cutter device is clogged, it was difficult to open the cutter opening/closing cover 30 when cleaning the clog because of the intake guide of the binding machine, which was previously difficult to do, but this problem has also been solved. A pivot portion of the opening/closing link 15a is provided on the upper surface of the knot cover 19.

If the cutter device becomes clogged with straw,
This is done by an alarm switch provided on the rotating part of the cutter opening/closing cover 30, but if the binding device becomes clogged, the alarm switch 12 is set between the tip of the binding device cover 10 and the upper plate 33 of the cutter device. It is set up. This alarm switch 12 is turned on when the binding machine cover 10 is lifted even slightly by clogged waste straw, and the switch is turned on to warn that the binding machine is clogged. When the blockage becomes even worse, the intake guide 3 is lifted further, the opening/closing link 15 is further lifted, and the lower side of the opening/closing link gradually rotates upward, much later than the alarm switch 12. Then, the engine stop switch 11 is turned ON, a separately provided stop motor is activated, the engine accelerator lever is moved to the stop position, the engine is stopped, and the entire combine is stopped. This engine stop prevents further clogging and destruction of the binding machine.

As shown in FIGS. 6 and 7, there are two intake guides 3a and 3b fixed to the opening/closing link 5a, with one intake guide 3a extending laterally. Another intake guide 3b extends in the direction of the opening/closing link.

As shown in FIG. 8, the pivot shaft 17a of the binding machine cover 10 is attached to the outer surface of the binding machine case 18.

Further, a cover 10b is provided downward from the left side surface of the binding machine cover 10. 16 is a discharge link device.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, when a straw jam occurs inside the straw tying machine, conventionally the tying machine cover is difficult to remove by tightening bolts, etc., and the entire tying machine has to be removed, or the straw gets stuck under the discharge port and the straw is clogged. I was cleaning out a blockage.

In contrast, in the present invention, the binding machine cover 10 is
The front part can be rotated to open and close using the rear part as a pivot point, and an intake guide 3 that guides waste straw to the binding device is provided as a member that rotates together with the binding machine cover, so that clogging of waste straw does not occur in the binding machine. In case, also,
There is a cutter device at the front of the binding machine, and if the cutter device becomes clogged, by rotating and opening the binding machine cover, the intake guide 3 can be removed at the same time as the binding machine cover 10 is rotated to open. This allows the clogged waste straw to be taken out from above the bundling device.

Second, in the past, the intake guide protruded from the nodule cover, etc., so it was necessary to remove it and take out the straw, or bend the intake guide to take it out. However, these problems can be resolved by attaching the intake guide 3 to the binding machine cover 10 side. It was.
