Description

[Detailed description of the invention] The present invention is a threshing device such as a harvester or combine harvester, in which a straw removal device consisting of an endless rotating band with a protrusion and a pinching rail is installed in a working position that projects laterally outward. and,
The present invention relates to a threshing device that can be switched between a non-operating position and a non-operating position close to the threshing device.

In order to provide the pincher rail in the above device, the pincher rail must also be switched between the working position and the non-working position. Either connect the pincer guide to a continuous position corresponding to the conveyance end side of the pincer guide, or
Alternatively, it was installed so that it could be moved in and out of the threshing device. However, in both cases, the pinching rail is composed of a single rod-like object, and
Since the pinch rail was supported by a pressing member,
When the amount of straw to be conveyed and removed changes and the amount of straw to be removed suddenly increases, the tip of the pinching rail becomes far away from the endless rotation band, and the straw that is being conveyed in advance is removed from the rail. It slips through between the loop and the endless rotating belt.
There was a drawback that it caused poor transportation.

In view of the above points, the present invention is designed so that the pinch rail can be rationally switched between a working position and a non-working position while connected to the threshing device, and this configuration is effectively used to transport and remove grains. It is an object of the present invention to enable waste straw to be transported well regardless of fluctuations in the amount of straw.

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

A running vehicle body is provided with a crawler traveling device 1, an engine 2 mounted at the rear, and a control handle 3 extending to the rear. A harvester is constructed by placing the harvester 4 on the side of the engine 2 and mounting a threshing device 5 thereon.

In the figure, 6 indicates a grain culm loading stand, and 7 indicates a paddy bag holder, both of which have two positions: a working position in which they protrude almost horizontally to the outside of the machine, and a non-working position in which they are stored on the side of the machine. It is provided so that it can be switched freely.

A waste straw conveying device 8 is provided in series with the feed chain 4, and the waste straw conveying device 8 is configured to be freely switchable between an active position in which it protrudes outward from the side of the machine and a non-active position in which it is brought close to the threshing device 5. However, in the working position, the threshed straw can be transported to a remote location outside the machine body, while in the non-working position, the entire machine body is constructed compactly.

The straw removal conveying device 8 is constructed by providing a pinching rail 10 below a belt 9 with projections, and wheels 11 and 12 are attached to the belt 9 with projections on the conveyance start end side and the conveyance end side, respectively. The case 13 is provided so as to be able to swing freely between an active position protruding outward from the side of the machine around the rotation axis P of the conveyance start end side wheel body 11 and a non-active position along the feed chain 4. There is. A lock pin 1 having a handle 14 connected to the case 13
5 is provided so as to be able to slide in and out, and a spring 22 is attached to the lock pin 15 to bias the lock pin 15 so as to displace it to the projecting side, and a locking hole (not shown) formed on the side of the threshing device 5 is attached to the lock pin 15. It is configured such that it can be fixed or unfixed in the working position and non-working position by engaging and disengaging the lock pin 15.

The pinching rail 10 is connected to the first rail member 10a.
and the second rail member 10b are pivotably connected to each other so as to be relatively swingable so that the first rail member 10b can bend freely.
The conveyance start end side of a is pivotally connected to the conveyance end side of the pinching guide 4a of the feed chain 4 so as to be relatively swingable, and a first rail member 10a is connected near the pivot point.
A first pressing member 16 is attached to press the belt 9 toward the protrusion belt 9 side. A bracket 17 is attached to the side wall of the threshing device 5, and a pinching rail is attached to the bracket 17 so as to extend over the conveyance terminal end side of the first rail member 10a and the conveyance terminal end side of the second rail member 10b. Second and third pressing members 18 and 19, which press and urge the belt 10 toward the protruded belt 9, are pivotably connected to each other so as to be swingable.

A connecting pin 2 is attached to the tip of the third pressing member 19.
On the other hand, a portion 21 for inserting and removing the connecting pin 20 is provided in succession on the conveyance terminal side of the second rail member 10b, and the pin 20 is inserted into and removed from the cylindrical portion 21. With this, the second rail member 10b is placed in a position along the protruded belt 9, that is, the pincer rail 10 is placed in the operating position, and the pin 2 is
0 is removed from the cylindrical portion 21, the second rail member 10b slides and hangs around the bending fulcrum, and the pinching rail 10 is brought into a non-operating position close to the threshing device 5. There is.

In the present invention, a chain with protrusions may be used in place of the belt with protrusions 9, and these chains are collectively referred to as endless rotating belts with protrusions 9.

This invention uses a combine harvester to remove straw from threshing.
It can also be applied to a waste straw conveying device that supplies waste straw to a waste straw binding device or the like that is attached to the threshing device 5 as an attachment.

In summary, the threshing device according to the present invention moves the pinching rails constituting the straw removal conveying device 8 to the first rail.
the first rail member and the second rail member;
The base end of the rail member is pivotally connected to the conveyance end side of the pinching guide of the threshing feed chain so as to be vertically swingable, and the base end of the second rail member is The first rail member is pivotally connected to the terminal end of the first rail member so as to be able to bend and swing freely in any direction, and the first rail member is connected to the base end and the terminal end of the threshing device. A third rail member is supported so as to be movable downward by first and second pressing members provided between the rail members, and a third rail member is removably constructed and connected to the second rail member and the threshing device. a working position in which the third pressing member is supported by a pressing member and along the rotating belt; and a non-working position in which the third pressing member and the second rail member are disconnected and hanging down along the threshing device. It is characterized by being configured to be switchable.

In other words, the pinching rail 10 is configured with two parts that can bend freely in the vertical direction, and the third pressing member 19 is connected or disconnected to connect the first rail member 10a and the second rail.
The second rail member 1
0b can be switched between the working position and the non-working position.Moreover, by effectively utilizing this configuration, in the working position, the conveyance start end and the conveyance end side of the pinching rail 10, and the portion near the waist bending fulcrum, respectively. is pressed toward the endless rotating belt 9 side by the first to third pressing members 16, 18, and 19, so that, for example, even if the amount of straw to be conveyed increases rapidly, the posture of the second rail member 10b is greatly changed. The first rail member 10a can move downward as a whole without any movement, and the waste straw transported in advance will not slip out from between the second rail member 10b and the endless rotation band 9. Even if the amount of conveyed and discharged straw fluctuates, the pinching rail 10
It is now possible to prevent the waste straw from separating greatly from the endless rotating belt 9, and the waste straw can be transported satisfactorily.
