Description

[Detailed Description of the Invention] The present invention relates to a device for collecting and discharging waste culms in a combine harvester, which is capable of collecting the waste culms discharged from a threshing machine in predetermined amounts and releasing the collected culms into a field.

Conventionally, the waste culm discharged from the threshing machine mounted on the combine harvester was collected in predetermined amounts and discharged into the field. The culm receiver provided below receives the culm from below and collects the culm, and when the collected culm reaches a predetermined amount, the culm receiver rotates downward and collects the collected culm. Since the culms were discharged into the field, when the culms naturally fall from the culm outlet, or when the culms that have fallen onto the culm receiver are blown away by the wind, they may fall onto the culm receiver. Not only is it not possible to collect the culm properly, but the culm discharged into the field remains in the same state as it was discharged from the culm discharge port, that is, the culm direction is in the same direction as the width direction of the machine. Since it is ejected in a direction perpendicular to the other, one end of the ejecting culm comes close to the unharvested field, and the ejecting culm is stepped on in the next reaping process, making it impossible to use the ejecting culm for secondary processing. There were flaws.

The present invention was devised in order to eliminate these drawbacks in view of the above-mentioned actual situation.The present invention has been devised in order to eliminate these drawbacks. A culm guiding body is provided which rotates upward in the opposite direction to the culm receiving body in order to form a discharge path in synchronization with the culm receiving body in a vertical direction that intersects with the culm receiving body. By forming the culm guide body to hang downward from the stock side to the tip side, the culm discharged from the culm outlet by the culm guide body can be prevented from being blown away by the wind. The culm can be collected in an orderly manner, and when the culm is released, the culm guide body, which is longer toward the tip side, provides resistance to the tip side of the culm, so that the plant head side is released first. Discarded straw in a combine harvester capable of discharging straw in a direction away from the unharvested field side, eliminating trampling of the discharged culm in the next reaping process, and supplying straw suitable for secondary processing of the culm. The purpose of the present invention is to provide a collecting culm discharge device.

The structure of the present invention will be explained with reference to an embodiment shown in the drawings. Reference numeral 1 denotes a traveling machine of a combine harvester, and the rear of a grain discharge port 2a of a threshing machine 2 mounted on the traveling machine 1.

When the receiving rod 8b is located at the receiving position inclined rearward and upward, the guide rods 13b, 13c, and 13d hang down approximately vertically to narrow the guide path A of the culm that intersects with the receiving rod 8b. The receiving rod 8b is located at a guiding position formed in a direction, and is interlocked with the rotation of the receiving rod 8b to a discharge position inclined rearward and downward.
The guide rods 13b, 13c, and 13d are rotated rearward and upward so as to be located at open positions where they open and form a discharge path B for the collected culms between them and the receiving rod 8b.

In addition, in the figure, 20 is the driver's seat, 21 is the grain culm reaping part,
22 is a grain storage section, and 23 is a stock clamping and conveying body.

Next, the operation of the present invention constructed as described above will be explained. In order to reap and harvest grain culms using a combine harvester, the grain culms harvested by the grain culm reaping section 21 are lifted up and conveyed, and the stalk side is held by the stalk clamping conveyor 23.
The tip side is threshed by the threshing machine 2 while being held between the ears. The grains are stored in a storage bag in the grain storage section 22, while the culms are discharged from the culm discharge port 2a and transferred to the culm conveying chain 3. The waste culm transported by the waste culm transport chain 3 to the transport end at the rear of the machine body is transferred to either the waste culm cutting device 4 or the waste culm collecting device for post-processing by switching the switching plate 5. be done. That is, when the switching plate 5 is rotating upward as shown by the imaginary line in FIG. 3, the waste culm is supplied to the waste culm cutting device 4, is cut, and is discharged outside the machine. On the other hand, when the switching plate 5 is horizontal as shown by the solid line in FIG. The culms will be collected and discharged outside the aircraft.

Here, the culm discharged from the culm outlet 6 is
The culm will fall onto the lower culm receiver 8, but at this time, the culm will hang down vertically in an intersecting manner toward the base end of the receiving rod 8b of the culm receiver 8. While guided by the trailing edge of the fuselage and the guide rods 13b, 13c, and 13d of the culm guide 13, which has a narrow guide path A extending toward the culm, it falls horizontally onto the lower end of the narrow guide path A. and is received on the receiving rod 8b. Then, the received culms are pressed and collected toward the fuselage by guide rods 13b, 13c, and 13d that are interlocked and connected to the coil bomber 10. Therefore, the culm and the receiving rod 8 falling from the culm discharge port 6
The culms received on the top b will be collected in an orderly manner without being disturbed by being blown away by the wind. Moreover, as the culms are collected, the receiving body 8 rotates in the direction of opening sequentially against the coil bomber 10 along with the guide rods 13b, 13c, and 13d due to the weight of the collected culms. The culm is the guide rod 13b, 1
It continues to be supported in a pressed manner by 3c and 13d.

When the culm received on the receiving rod 8b reaches a predetermined amount, the load due to the weight of the culm overcomes the force of the coil bomber 10, and the receiving rod 8b and the guide rod 1
3b, 13c, and 13d open in opposite vertical directions and are located at the release position and the open position, respectively, and the release path B of the collected culm is formed to be released into the field. At this time, the tip side guide rod 13c is longer and the imaginary line Y-Y connecting the lower end of each guide rod becomes steeper than the imaginary line Even if the contact by the guide rod 13b is released, the tip side guide rod 13d is still in contact with the tip of the culm, so the tip side of the culm receives resistance from the tip side guide rod 13d, and the tip side guide rod 13d The rod 13d serves as a discharge guide, and the culms are discharged from the plant side in advance. Therefore, the collected culms are not discharged in a generally parallel manner in the width direction of the machine in a collected state, as in the case where the guide rods 13e are made of equal length as shown in FIG. , as shown in FIG. 6, it is discharged and guided in a direction that does not reach the uncut land side which is inclined with respect to the width direction of the machine toward the harvested land side. For this reason, the distance from the unharvested field side to the base of the culm is longer than that of the guide rod 13e of the same length (L ₁ <L ₂ ), and the culm released during the next reaping process is trampled. Therefore, the threshed culm can be supplied for secondary processing.

In summary, the present invention provides a culm receiver below the culm discharge port of a combine harvester that receives and collects a predetermined amount of culm, and above the culm discharge port from the culm discharge port. A culm guide that forms a narrow guide path to the culm receiver is rotatably vertically disposed vertically intersecting the culm receiver, and is connected to the culm receiver. The culm discharge path is arranged such that the culm guide body rotates upward in conjunction with the culm receiving body which rotates downward when a predetermined amount of the culm collects. In addition to being interlocked and connected to form a culm, the above-mentioned discharge culm guide is made to hang longer toward the tip side, and is configured as a discharge guide body that comes into contact with the tip side at the time of discharge of the discharge culm and guides the discharge culm toward the harvested land side. , guided by a narrow guide path formed by vertically hanging culm guides,
As the culm falls and is caught on the narrowly partitioned culm receiver, the culm at the time of the fall or the culm on the culm receiver may be blown away by the wind and become disturbed. The culms can be collected in an orderly manner without any problems. Moreover, when releasing the collected culm, the culm guide body, which is longer toward the tip side, acts as a release guide that comes into contact with the tip side of the culm, providing resistance to the tip side, so that the plant head side releases in advance. Since the waste culm can be released and guided in the direction away from the unharvested land side, it is possible to eliminate the trampling of the released waste culm in the next reaping process and to supply the waste culm as it is threshed for secondary processing. be.
