Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a swinging packer that rakes and supplies threshed waste straw into the bundling space and projects upward from below the bottom surface of the waste straw supply path. A regulating device for preventing the floating straw from floating by the swinging packer,
This invention relates to a threshing straw binding device that swingably extends from the upper side to the lower side of the supply path and is biased downward.

[Conventional technology]

Conventionally, there is a device configured as described above, as shown in Japanese Utility Model Application Publication No. 104332/1983. In this example, the shape of the restrictor is fan-shaped, and the lower edge of the restrictor is inclined. By arranging the waste straw in such a manner that it blocks the waste straw supply path, when sending the waste straw to the bundling space, the waste straw comes into contact with the lower edge of the regulating device, and while lifting the regulating device, in other words, it moves downward. While floating is suppressed by the biasing force, the waste straw is sent into the bundling space.

Moreover, since the regulating device of this example has an arcuate surface formed on the swing end side, the structure is such that the waste straw fed into the bundling space does not flow backwards due to the arcuate surface.

[The problem that the idea aims to solve]

Now, considering the restricting device in the above example, in this example, the lower edge of the restricting device is arranged in an inclined position as described above, so the lower edge of this restricting device is located on the side of the waste straw supply path. It is separated from the bottom surface of the waste straw supply path on the side, and is close to the bottom surface of the waste straw supply path on the lower side of the waste straw supply path.

Therefore, when the waste straw is sent to the bundling space, a gap is formed between the waste straw and the regulating device on the upper side of the supply path, and the lifting of the waste straw cannot be prevented, making it impossible to convey it smoothly. However, there is room for improvement.

In particular, the swing packer used for conveying the waste straw has a structure that makes it easy to apply an upward force to the waste straw in the upper side of the area where the conveying force is applied to the waste straw. Therefore, it is easy to cause the inconvenience that it is difficult to carry out smooth conveyance, and if the volume of the waste straw is small, this inconvenience is exacerbated.

An object of the present invention is to rationally construct a device that does not easily lift the waste straw from the bottom surface of the waste straw supply path in the conveyance area of the swing packer even when the volume of the waste straw is small.

[Means to solve the problem]

The features of this invention are as mentioned above, the swinging pack car,
In the threshing waste straw binding device provided with a regulating device, the regulating device is set and arranged in a posture substantially parallel to the bottom surface of the waste straw supply path, and the extending end of the regulating device is provided with:
The present invention is characterized in that a rising portion is provided with a length approximately equal to the total height of the supply channel to restrict the backflow of waste straw to the upstream side of the supply channel, and its operation and
The effects are as follows.

[Effect]

When the above characteristics are configured as shown in FIGS. 4 and 5, for example, the regulating devices 18 and 19 are arranged in an attitude substantially parallel to the bottom surface 17 of the waste straw supply path, so that the waste straw is not sent to the supply path 15. In this case, both on the upper and lower sides of the waste straw conveying direction,
It becomes possible to bring the waste straw into contact with the regulating tools 18, 19, and since a stronger biasing force acts on the regulating tools 18, 19 on the upper side than on the lower side, the swinging packer 1
Even if a strong force is applied upward from 6, the removed straw is prevented from floating.

Further, the extending ends of the restrictors 18 and 19 are provided with rising portions 18a and 19a, and the rising portions 18 and 19 are provided with rising portions 18a and 19a.
Since the lengths a and 19a are set to be approximately equal to the total height H of the supply path 15, it is possible to reliably prevent the waste straw fed into the bundling space 10 from flowing back.

[Effect of idea]

Therefore, even when the volume of waste straw is small, in the conveyance area of the swing packer, the waste straw can be smoothly fed without floating from the bottom of the waste straw supply path, and moreover, the backflow of the waste straw fed into the bundling space can be avoided. This resulted in a device that can prevent this and make the binding in a well-organized state.

〔Example〕

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

As shown in FIG. 1, when a grain culm bundle is artificially supplied to a receiving table 1, the supplied grain culm is supplied to a handling room by a clamping conveyance device 4 consisting of a feed chain 2 and a clamping rail 3, and is threshed. A harvester is constructed by mounting a threshing device 5 configured such that threshed waste straw bundles are carried out of the machine by the transport device 4 on a self-propelled machine base having a crawler traveling device, a driving unit (not shown), etc. It has been done.

A device 6 for tying a plurality of threshed waste straw bundles at a time on the waste straw discharge port side of the threshing device 5, and a device for raking and supplying the waste straw bundles from the clamping and conveying device 4 to the receiving port of the bundling device 6. 7, and the number of waste straw bundles supplied to the binding device 6 is measured based on the number of times a swing contact sensor 8 makes contact with the transported waste straw bundles at the terminal end of the clamping and conveying device 4. In addition to providing a device 9, the binding device 6
A one-turn clutch (not shown) is connected to the measuring device 9 so as to be operated every time the number of measurements by the clutch reaches a set value, and as a result, along with the threshing process,
A plurality of threshed waste straws are tied together and released.

The waste straw binding device 6 is constructed as follows.

That is, as shown in FIG.
A string supply section having a string supply needle 11 and the like is provided below the string holder 1 , and a string holder 1 is provided above the binding space 10 .
