Description

[Detailed description of the invention] [Industrial application field] The original F! A is equipped with a stock alignment device consisting of a reciprocably movable stock end press plate that perfectly aligns the stock ends of the waste straw transported from the threshing device in a sideways position by a conveyance device, and a bundling device. Concerning the waste removal and waste treatment mechanism.

[Conventional technology]

The above-mentioned waste straw processing mechanism is a device that binds and shreds waste straw discharged from threshing equipment mounted on harvesters, combines, etc., but in the bundling state, In harvesters, the grain culm is artificially supplied, so the position of the end of the straw that is sent out from the threshing device is not constant, and in combine harvesters, the length of the harvesting rod and the handling depth must be adjusted frequently. As a result, the position of the stock end of the waste straw sent out from the threshing device is often inconsistent. Therefore, from the viewpoint of subsequent processing such as drying in the sun, it is desirable to bundle the waste straw with the ends of the plants aligned.

Therefore, as a mechanism for feeding waste straw discharged from a threshing device to a binding device while aligning the ends of the straw, for example,
As shown in Japanese Patent Publication No. 57-5487, a fixed guide plate for aligning the ends of the stock is automatically moved in the direction of the culm of the removed straw according to the position of the end of the removed straw being conveyed. There is a mechanism to do this.

[Problem that the invention seeks to solve]

The above-mentioned guide plate type is effective when the waste straw is relatively hard and strong, but if the waste straw is soft and weak, it may cause stem breakage etc. when the waste straw starts to come into contact with the guide plate. This may occur and sufficient stocks may not be available. Therefore, as an example of a means to solve this problem,
There is a mechanism, such as the one disclosed in Japanese Patent No. 8181, which is equipped with a rocking drive type stock end pressing plate and forcibly knocks the stock ends to align, but the rocking drive type reciprocating mechanism such as This requires a larger device space than the guide plate structure.

Here, an object of the present invention is to make the waste straw processing mechanism compact and to improve its functionality by using the above-mentioned stock alignment device equipped with the forcibly driven oscillating press plate.

[Means for solving problems]

The feature of the present invention is that, in the waste straw processing mechanism described above, a pair of position sensors for detecting the presence or absence of waste straw are installed at the plant base on the conveyance route, in the direction of the waste straw culm, and against the stock alignment device. arranged in a fixed position, and the end of the reciprocating operation range of the stock end pressing plate in the stock alignment device is substantially aligned with the position of the pair of position sensors, so that the end of the waste straw stock is located between the position sensors; A drive control mechanism for relatively changing the positions of the stock alignment device and the conveying device in the direction of the straw removal culm is provided, and its functions and effects are as follows.

[For production]

When configured as described above, of the pair of position sensors,
If the position sensor on the tip side is in the detection state and the position sensor on the stock end side is in the non-detection state, the stock end of the discarded straw is not located between the two position sensors. The stock end of the waste straw is fed into the operating range of the stock end pressing plate, and the stock is normally aligned.

For example, if both position sensors become non-detecting,
This means that waste straw will not be sent to the stock alignment device,
The drive control mechanism relatively moves the stock sorter or the conveying device until the position sensor on the tip side enters the detection state.

Also, if both position sensors are in the detection state, the middle of the waste straw stem culm will be fed into the operating range of the stock end pressing plate, so until the position sensor on the plant end side becomes non-detecting, The drive control mechanism moves the stock sorter 1 or the transport device in the opposite direction to that described above.

〔Effect of the invention〕

As described above, by configuring the waste straw processing mechanism so that the stock end of the waste straw can be automatically fed into the operating range of the reciprocating stock end press plate, the waste straw processing efficiency has been improved. In addition, by matching the operating range of the stock end pressing plate with the interval between the position sensors, the operating range of the stock end pressing plate can be used effectively without waste, and the operating range of the stock end pressing plate can be set small. The I/C allows the entire waste straw processing mechanism to be configured compactly.
