Description

[Detailed description of the invention] [Industrial field of application] The present invention has a structure that includes a
Two types of waste straw processing devices, at least one of which is a drive type, are provided, and waste straw sent out from the waste straw transport device by forward and reverse switching is provided between the waste straw transport device and both of the waste straw processing devices. This invention relates to a waste straw processing device for a threshing machine, which is equipped with a waste straw supply device that can be changed between supplying straw to one processing device and supplying straw to the other processing device.

[Conventional technology]

Conventionally, as a device configured as described above, there is one shown in Japanese Patent Application Laid-Open No. 56-96626,
In this reference, the waste straw processing device consists of a cutter and a binding device, and the waste straw supply device is configured in the form of a drum, and a system that transmits power to the binding device in conjunction with switching the rotational direction of the waste straw supply device. The clutch is configured to be operated on and off.

[The problem that the idea aims to solve]

Now, considering the device of the above-mentioned reference, in this reference, the feeding direction of the waste straw can be changed by switching the driving direction of the waste straw supply device, so
This is advantageous in that the number of parts can be reduced because the mechanism for feeding waste straw to two types of waste straw processing apparatuses requires only a single waste straw supply device.

However, this reference requires a transmission system to drive the waste straw supply device and a system to drive the bundling device, so two transmission systems are always required, further reducing the number of parts. There is room for improvement from the viewpoint of reducing the amount of power and reducing the installation space for the transmission system that transmits power to the binding device.

The purpose of the present invention is to rationally improve a device that selectively sends waste straw to two types of waste straw processing devices using a waste straw supply device that is driven in the forward and reverse directions as described above. The drive system of one of the processing devices is configured to have as few parts as possible and to save space.

[Means to solve the problem]

A feature of the present invention is that in an apparatus comprising a waste straw supply device configured as described above and two types of waste straw processing devices, forward and reverse switching is possible in order to transmit forward and reverse power to the waste straw supply device. By driving the waste straw supply device in a predetermined direction, the waste straw supply device is connected between the transmission system in which the mechanism is installed and the waste straw processing device to which waste straw is supplied from the waste straw supply device. , the drive system has a one-way rotating clutch that transmits the power of the transmission system to the waste straw processing device only when driven in this predetermined direction, and its operation and effects are as follows. That's right.

[Effect]

When the above characteristics are configured as shown in FIGS. 1 and 2, for example, when the waste straw supply device 9 is driven in the direction of sending the waste straw to the binding device 8 by operating the forward/reverse switching mechanism 11, The power from the transmission system 10 (common drive rotating shaft) for transmitting the power from the forward/reverse switching mechanism 11 to the waste straw supply device 9 is transmitted to the binding device 8 via the one-way rotation clutch 12. Therefore, the binding device 8 is activated.

Further, when the waste straw supply device 9 is driven in the opposite direction, the power to the binding device 8 is cut off by the one-way rotary clutch 12.

In other words, with this configuration, the transmission system can be shared, and a dedicated transmission system for transmitting power to the bundling device 8 (an example of a waste straw processing device) is not required.

[Effect of idea]

Therefore, by a relatively simple modification of forming a drive system with a one-way rotating clutch to transmit power from the transmission system that transmits power to the waste straw supply device to the waste straw processing device, two types of waste straw processing can be achieved. One of the drive systems in the device can be configured with a small number of parts, and the space in which this drive system is installed can be reduced.

A binding device 8 (an example of a waste straw processing device) having B is arranged with the binding space 5 facing in the front-rear direction.

Between the cutter 4 and the bundling device 8 and the waste straw transport device 3, there is a state in which waste straw sent out from the waste straw transport device 3 is supplied to the cutter 4 and a state in which it is supplied to the bundling device 8 by switching between forward and reverse directions. A waste straw supply device 9 is provided which can be switched between the two states.

The waste straw supply device 9 has conveyor chains 9A, 9A having a length extending from the front part of the cutter 4 to the front part of the bundling device 8, respectively, on the stock side and the head side of the waste straw transport device 3. These conveyor chains 9
A and 9A have clamping rails 9 on the upper conveyance surface, respectively.
