DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a combine
The present invention relates to a straw conveying device provided in a threshing device such as a Vesta.

[0002]

2. Description of the Related Art Conventionally, a threshing apparatus such as a combine or a harvester performs threshing by a handling cylinder provided in a threshing room while transporting a harvested culm backward by a feed chain, and discharges after the threshing. The straw is taken off from the end of the feed chain by a straw conveying device and is conveyed obliquely rearward. The straw conveyed obliquely rearward by this straw conveying device is fed into a straw processing device such as a cutter or a knotter, and is shredded or bound.

[0003] In such a threshing apparatus, the straw conveying device is configured to be a nipping and conveying type by a straw chain and a guide rod disposed below and facing the straw chain. Therefore, the amount of the sandwiched straw is excessively large between the straw chain and the guide rod, resulting in clogging, or at the transfer portion from the end of the feed chain to the straw conveying device, due to poor transfer. If the waste is clogged, the threshing work cannot be continued.

Therefore, for example, Japanese Utility Model Application Laid-Open No. 58-18723.
As disclosed in Japanese Patent Publication No. 6, when the lifting force of the straw being conveyed to the straw chain acts more than a predetermined amount, the straw chain is configured to be lifted upward. A technique for opening the space between the guide rod and the guide rod has been considered.

[0005]

Since the above-mentioned conventional straw conveying device is of a sandwiching conveying type, the straw is transported between the straw chain and the guide rod or at a transfer portion from the feed chain. When clogging occurs, it is difficult to remove the clogging, and time and labor are required for this removing operation, resulting in extremely low work efficiency.

The technique disclosed in Japanese Utility Model Laid-Open Publication No. 58-187236 is a kind of safety device. The holding force of the transport chain affects the possibility of opening, and if it is too strong, the safety device is used as a safety device. Will no longer function,
If it is too weak, there is a drawback that ordinary clamping and conveying cannot be performed.

[0007]

The present invention takes the following technical means in order to solve the above-mentioned problems. That is, in the invention of claim 1, threshing is performed by the handling drum 12 provided inside the threshing room 1 while the harvested culm is transported backward by the transport device 8, and the straw after the threshing process is discharged by the straw transport device 13 In the threshing device which takes over from the terminal end of the transport device 8 and transports diagonally rearward,
The straw chain 6 and the guide rod 9 constituting the straw transport device 13 are configured to be able to be separated from each other by raising the straw chain 6, and the rising amount of the starting end side of the straw chain 6 is adjusted to the terminal side. 3. The structure of a straw conveying device in a threshing device characterized in that the threshing device is configured to be larger than the rising amount. In the threshing device in which threshing is carried out by a handling cylinder 12 and threshing after the threshing process is carried over from a terminal end of the transporting device 8 by a straw transporting device 13 and is transported obliquely rearward, the straw transporting device 13 The constructed straw chain 6 and the guide rod 9 are configured to be able to be separated from each other by raising the straw chain 6, and the rising amount at the start end side and the rising amount at the terminal end side of the straw chain 6 are substantially the same. It is characterized by comprising It is obtained by the configuration of the straw discharge conveying device in threshing apparatus.

[0008] With this configuration, the harvested culm is transported by the transport device 8.
While being conveyed rearward, threshing is performed by the action of the handling cylinder 12 provided inside the threshing room 1. And the waste straw after the threshing process is taken over from the transport device 8 to the straw transport device 13 and transported diagonally rearward, and is fed into a cutter or a knotter to be shredded or bound.

During the threshing operation, the straw conveying device 13
In the case where the straw is clogged between the straw chain 6 and the guide rod 9 or in the transfer portion from the transport device 8, the straw chain 6 is raised to separate the straw chain 6 and the guide rod 9 from each other. Let
The clogged straw can be removed. In addition, in the first aspect of the present invention, since the start end of the straw chain 6 rises more greatly than the end, the handover from the end of the transport device 8 to the start of the straw transport device 13 is large. It is released, and the straw trapped here can be easily removed.

According to the second aspect of the present invention, since the starting end and the end of the straw chain 6 rise by substantially the same amount, from the starting end to the end of the straw transporting device 13, The space between the transport chain 6 and the guide rod 9 is wide open, and the straw trapped therein can be easily removed.

[0011]

As described above, in the invention according to the first aspect, threshing is performed by the handling cylinder 12 provided inside the threshing room 1 while the harvested grain culm is transported backward by the transporting device 8,
In the threshing device in which the straw after the threshing process is taken over from the terminal end of the transport device 8 by the straw transport device 13 and transported obliquely rearward, the straw chain 6 and the guide rod constituting the straw transport device 13 are provided. 9 is configured to be able to be separated by raising the straw chain 6, and that the rising amount at the start end side of the straw chain 6 is configured to be larger than the rising amount at the terminal end side. Because of the structure of the straw conveying device, the transfer portion from the end of the conveying device 8 to the start end of the straw conveying device 13 is greatly opened, and the waste clogged here can be easily removed, and the work efficiency can be improved. improves.

According to the second aspect of the invention, the harvested grain culm is threshed by the handling drum 12 provided inside the threshing room 1 while being conveyed backward by the conveying device 8, and the straw after the threshing is discharged. The conveying device 8 by the straw conveying device 13
In the threshing device which takes over from the end of the threshing and conveys obliquely rearward, the straw chain 6 and the guide rod 9 constituting the straw conveying device 13 are configured to be separable by raising the straw chain 6, and Since the rising amount on the starting end side and the rising amount on the terminal end side of the straw chain 6 are configured to be substantially the same, the structure of the straw conveying device in the threshing device is characterized in that
The opening between the transport chain 6 and the guide rod 9 is widely opened from the start end side to the end end side of the straw conveying device 13, so that the straw trapped here can be easily removed, and the working efficiency is increased.
