Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waste straw processing device for a threshing device that can freely switch waste straw discharged from a threshing section between a shredding state and a non-shredding and bundling state.

As a waste straw processing device having the above-mentioned functions, for example, there is a device that separately installs a waste straw cutter and a binding device at the end of each of different waste straw conveyance paths, and switches the waste straw conveyance path to change the processing state. However, in this case, when changing the route, the posture of the waste straw may be disturbed and the processing may be hindered.

Furthermore, if the waste straw cutter and the binding device are mounted on the machine body and are placed one behind the other in the conveyance direction, the entire threshing device becomes longer due to the waste straw processing device, making it inconvenient to store and transport.

To solve this problem, it is conceivable to switch the straw removal processing state by replacing the removal straw cutter and the bundling device at the end of the removal straw conveyance path, but there is a problem that the switching operation becomes troublesome.

In view of these circumstances, the present invention has been developed to provide a threshing device that can easily and efficiently switch waste straw between the two processing states described above, while having a simple structure with a short overall length of the threshing device and a short power transmission system. The purpose of the present invention is to provide a waste straw processing device.

The waste straw processing device of the threshing device of the present invention has a straw cutter that can be freely switched between a shredded state and a non-shredded state in which the straw is passed downward as it is, disposed outside the straw exit of the threshing section. A waste straw bundling device for bundling and releasing the non-shredded waste straw is arranged below the waste straw cutter, and between the waste straw cutter and the bundling device, there are positions in which the shredded straw is guided and discharged to the outside of the machine and a non-shredded straw binding device. It is characterized by being provided with a guide plate that can be freely switched to a position that guides the shredded straw to the binding device.

That is, according to the above structure, many advantages can be obtained as follows.

■ Since the waste straw cutter and the waste straw binding device are arranged above and below, the overall length of the threshing device can be shortened without increasing the length of the waste straw processing device in the front-rear direction.

◎ Regarding the above-mentioned vertical relationship, in the present invention, the cutter is on the top and the bundling device is on the bottom, so it is simple to pass through the waste straw cutter as a long straw and guide the waste straw that falls due to its own weight with a guide plate. With this structure, the waste straw can be supplied to the bundling device, and compared to a system that changes the processing state by switching the waste straw conveyance route, the disturbance in the posture of the waste straw can be suppressed and two-state processing can be performed better.

0! 'l. In order to obtain only the above-mentioned advantages, the present invention has a major feature in that the above-mentioned guide plate is provided between the waste straw cutters and the waste straw binding device which are arranged above and below.

In other words, if the waste straw tying device is located below the waste straw cutter, it is easy to imagine that the shredded straw will fall onto the operating portion of the tying device and accumulate, leading to malfunction of the tying device.

In the present invention, since the shredded straw is guided out of the machine by the guide plate, it is possible to ensure good operation of the binding device provided under the straw removal cutter.

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

Figure 1 shows the entire combine harvester.

2. Reaping device for raising and reaping planted stems from the front to the rear of the traveling vehicle body 1. Vertical conveyance device 3. Threshing device4. A waste straw processing device 5 is installed, and the planted stem culms are pulled up and harvested, conveyed vertically, placed in a horizontal position, and passed to the feed chain 6 of the threshing device 4 so as to be held at the stock end, and then transferred to the threshing section 4a. The waste straw that has been treated and threshed is sent to the waste straw processing device 5, and is configured to be either shredded or non-shredded and bound.

FIG. 2 shows the structure of the waste straw processing device 5. As shown in FIG.

A waste straw conveying device 8 is provided with its starting end facing near the terminal end of the feed chain 6 and the waste straw outlet 7 of the threshing section 4a, and which sends waste straw rearward in a horizontal position.

The two blade shafts 9a and 9b are arranged side by side in the horizontal direction, and one is arranged so as to be far from the other. A disk-shaped cutter 9 that can be freely switched between processing states is disposed below the terminal end of the waste straw conveying device 8.

Then, with the entrance of the focusing space A facing upward, needle 1
A binding device 10 is provided below the cutter 9, and the binding device 10 has a knot 0a and a knot 10b facing each other on both the front and rear sides of the space A.

And, between the upper and lower parts of this cutter 9 and the binding device 10,
A guide plate 11 configured to change the direction of inclination in conjunction with switching of the cutter 9 is provided, and in the shredding state, the guide plate 11 is tilted downward toward the rear side of the binding device 10 to perform shredding. The straw is allowed to fall through the rear side of the bundling device 10, and is tilted downward toward the entrance of the focusing space A of the bundling device 10 in a non-shredded state, so that the long straw that has passed through the cutter 9 is collected into the focusing space. It is designed to guide the user to enter A.

With this structure, the waste straw sent from the waste straw conveying device 8 can be shredded by switching the cutter 9.
It is configured so that it can be switched to a non-shredding and bundling processing state.

In order to transmit power from the threshing device 4 to the waste straw processing device 5, the conveying device 8. Cutter9. A winding transmission device 13 that serially drives the binding device 10 is connected in an interlocking manner.

Furthermore, as shown in FIG. 4, if a bypass path B is provided that bypasses the front side of the cutter 9 and goes from the terminal end of the conveying device 8 to the binding device 10, the cutter 9 can be prevented from getting clogged during shredding. When this occurs, the waste straw can be bundled and released through the bypass path B, thereby preventing clogging of the conveying device 8 and feed chain 6 due to the clogging of the cutter 9, and preventing operations such as threshing and reaping from being obstructed. You will be able to do this.
