Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a stock arrangement mechanism for a waste straw binding device.

[Conventional technology]

In the stock arrangement mechanism of this type of waste straw bundling device, an endless rotating band for collecting stock is wound behind the conveyance chain in a state where the end approaches the conveyance chain, and the stocks of waste straw transported by the conveyance chain are wound. There is a known structure in which the ends are pressed to move the plant toward the tip and at the same time the ends of the plant are aligned.

[Problem that the invention attempts to solve]

However, since the pressing force is sufficiently large to perform the above-mentioned actions at the same time, a small number of the stock ends of the waste straw protrude toward the endless rotating belt side compared to the stock ends of other waste straws. In some cases, there was a risk that it would bend. Furthermore, since the waste straw is pressed in a bulky state, the overall transfer is performed relatively well;
It was not very effective in aligning the ends of a few stocks.

In view of the above-mentioned circumstances, the purpose of the present invention is to enable efficient transfer of waste straw and stock arrangement.

[Means for solving problems]

The characteristic structure of the present invention, which has been made to achieve the above object, is that a bucket-shaped protrusion protruding from the outer circumferential surface of the rear part of the conveying chain presses the end of the waste straw and transfers it toward the ear tip. The present invention is equipped with a stock alignment device that winds the endless rotating band for stock gathering and also knocks the ends of the removed straw gathered behind the endless rotating band, and its functions and effects are as follows. That's right.

[Effect]

The waste straw is conveyed from the threshing device in a horizontal position by the conveyor chain, and the end of the plant is pressed by the protrusion of the endless rotating belt at the rear of the conveyance path, and the straw is transferred laterally toward the ear tip, and then it is transferred to the end of the plant. An alignment device knocks the ends of the stock to align them.

Therefore, since the endless rotation band only needs to apply a pressing force to the end of the plant to transfer the waste straw, there is less risk of the waste straw being bent even if the end of the plant protrudes. In addition, the stock alignment device taps the end of the stock, so
Even if the waste straw is stuck together, the shock and vibration when it is struck will loosen the catch and make it easier to line up. Furthermore, since the protrusions protruding from the outer circumferential surface of the endless rotating band are bucket-shaped, they prevent the end of the stock from slipping when pressed by the endless rotating band, and at the end rotating part, the rotation is used to remove straw. push forward.

[Effect of idea]

The above effects work together to make it possible to transfer the waste straw and arrange the stock well.

〔Example〕

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

As shown in Figures 3 and 4, the threshing straw carried out from the handling room (not shown) is placed at the rear of the thresher 1 in a horizontal position, and is transported by holding the stock side at the rear of the machine. In addition to providing a chain 2 and a head side locking chain 3, a shredding device 5 that shreds and discharges the threshed waste straw with a disc cutter 4, and bundles the threshed waste straw in a set amount in a sideways posture and discharges it to the rear of the machine. A bundling device 6, which pinches and conveys the waste straw bundle from the bundling device 6 to a location corresponding to one horizontal side at the rear of the machine,
Conveyance and discharge device 7 that discharges and drops as if standing in a field
is installed at the rear of the threshing device 1, and by vertically swinging the lid 8 around the axis P, it is possible to release the threshed straw in shreds or to stand it up in the field in the form of long straw bundles. This is a threshing and waste straw processing device for a combine harvester.

As shown in FIGS. 2 and 3, on the side of the waste straw conveyance path R for supplying the waste straw to the bundling space S in a sideways posture, the waste straw is distributed on the upper side and the lower side of the conveyance path R. Drive roller 9 and idle roller 10
are supported by a frame 11 so as to be rotatable around the vertical axis, and an endless belt 12, which is an example of an endless rotating belt that acts on the stock end of the waste straw in the conveyance path R, It is wound around both rollers 9 and 10 so as to be rotationally driven to convey the straw to the bundling space S side.

As shown in FIG. 1, the idle roller 10 is
It is located α rearward from the tip side with respect to the drive roller 9,
Its horizontal distance L is approximately 400 mm. Further, as shown in FIG. 2, the endless belt 12 has a width W of about 100 mm.
mm, and a bucket-shaped protrusion 14 with a width of about 50 mm is provided on the outer circumferential surface thereof in a tilted state of about α.
Note that α is approximately 20 degrees. The protrusion 14 has a height h of about 20 mm in a tilted state, a front-to-back width w of about 10 mm, 15 mm of both ends a are formed obliquely, and the peripheral edge is bent forward.

By arranging the idling roller 10 on the lower side of the conveyance path closer to the tip side than the drive roller 9 on the upper side, and by providing protrusions 14 on the endless belt 12, the endless belt 12 moves the waste straw backward. At the same time, the protrusion 14 presses the end of the plant and transfers the waste straw horizontally by about 400 mm toward the head side, and furthermore, in the terminal rotation section, the waste straw is moved almost in front of the action position of the packer 15 of the bundling device 6. It is configured to be pushed forward.

The terminal end side of the endless belt 12, that is, the binding space S
On the stock side, there is a stock arrangement plate 16 that swings about the axis _P2 as a fulcrum and strikes the stock end of the waste straw, and a crank mechanism 17 that swings the stock arrangement plate 16. A device 18 is provided, and after knocking down the ends of the waste straw and bundling it, it is supplied to the rear conveying and discharging device.
