Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a vertical conveyance device between a reaping device and a threshing device to convey the reaped grain culm in a substantially vertical posture, and then changes the posture to a substantially horizontally lying posture. The present invention relates to a grain culm clamping and transporting device in an agricultural machine configured to inherit the clamping and transporting device of the present invention.

Conventionally, the grain culm holding and conveying device in this type of agricultural machinery has been composed of an endless band for transferring the stock end as a stock end holding device and a grain end locking and transporting device, as shown in Japanese Utility Model Publication No. 44-28997, for example. The threshing feed chain was configured to directly receive the grain culms conveyed by the endless belt that engaged with the ears. There was no extra space to feed the grain to the starting end and thresh it by hand, and the threshing feed chain was configured in the form of an atsper chain.
The drawback was that it was difficult to handle manually.

The present invention aims to facilitate manual handling work and to successfully solve new problems caused thereby.

The characteristic structure of the present invention for achieving the above object is as follows:
A threshing device equipped with an underchain-type feed chain is mounted on the machine base, and the starting end of the feed chain, which protrudes forward of the machine body beyond the side wall of the threshing machine on the side of the grain culm supply port, is tilted diagonally downward toward the front of the machine body. The vertical conveying device is configured to inherit grain culms that are in a substantially horizontal horizontal position, and conveys the grain culms that have been harvested by the harvesting device at the front of the machine in a substantially vertical position and delivers them to the starting end of the feed chain. The grain stalk guide rod, which is composed of a device and an ear tip locking and conveying device, and extends from a position near the terminal end of the stock head clamping and conveying device to a position above the conveyance working surface of the starting end of the feed chain, is connected to the grain root clamping and conveying device. It is pivotally connected to the clamping rail, and the free end side is elastically biased toward the feed chain conveying surface side, and this configuration provides the following effects.

That is, the threshing feed chain is constructed in an underchain type, and the starting end side of the feed chain is exposed, and the grain culm placed on the exposed starting end of the threshing feed chain is
Since the grain culm guide rod that is elastically biased can receive the feeding action of the threshing feed chain while preventing the grain from falling off, the vertical conveying device can be connected so that its terminal end is the starting point of the grain culm holding of the threshing feed chain. It is not necessary to arrange them so close that they overlap, and therefore it is easy to form a space for manual threshing at the starting end of the threshing feed chain.

In addition, the grain culm guide rod extends not from the threshing feed chain side but from the pinning rail side of the vertical conveying device, so when threshing by hand, the grain culm is placed on the grain culm guide rod. , manual handling work can be performed while sliding, for example, extending the grain guide rod from the threshing feed chain side, that is,
When handling grain by hand, place the grain on the guide rod and let it slide, such as when pivotally connecting the grain guide rod to the starting end of the clamping rail of a threshing feed chain. If this is not possible, remove the grain stalk guide rods one by one, or lift the grain stalk guide rods upward to a non-working position with one hand, place the grain stalks on the starting end of the feed chain, and then lift the grain stalks by hand. There is no hassle of having to handle the product.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The clamping and conveying device comprises a clipper-type reaping device 1, a feed chain 6, and a clamping rail 7, and clamps and conveys the grain culm to be threshed from above and below. (Threshing feed chain) It has a threshing device 2 whose clamping conveyance direction of 17 is aligned with the direction of movement of the machine body,
Between the two devices 1 and 2 located in the front and back, there is a stock clamping and conveying device 3 that grips and transports the stock base of the harvested grain culm from the left and right in a substantially vertical position, and a stock head holding and conveying device 3 that transports the stock head of the harvested grain culm in a non-clamped state. An intermediate conveying device is constructed by having a tip locking and conveying device 4 for locking and conveying the ears and a bar-shaped guide rod 18 for tipping the ears, and both intermediate conveying devices 3 and 4 are provided.
After changing the reaped grain culm from a substantially upright position to a lying threshing position by making the conveyance terminal end face the starting end of the threshed culm holding conveyance device 17 of the threshing device 2 and the supply port 8 to the threshing chamber 2a. , put the tip of the grain in the threshing chamber 2a,
In a combine harvester configured so that the stock head section is transferred to the clamping and conveying device 17, and equipped with a crawler-type self-propelled device 9 below each of the devices 1, 3, 4, and 2, From the clamping rail 3a of the intermediate grain culm stock clamping and transporting device 3 located on the upper side of conveyance at the grain transfer point between the two grain stalk holding and conveying devices 3 and 17 whose surfaces are perpendicular to each other, to the lower side of conveyance. A single grain culm guide rod 1 is installed on the starting end hanging slope part 6a of the feed chain 6 that protrudes forward of the machine body from the clamping rail 7 on the side of the clamping and conveying device 17 that is located.
This grain guide rod 10 is made of an elastic material, is swingable around a horizontal axis 19, and is elastically biased toward the feed chain 6 via a spring 20. , and is configured to be elastically displaceable in any direction, up, down, left, or right with respect to the two holding surfaces that are orthogonal to each other. In addition, 1 in the figure

Reference numerals 5 and 16 are cover bodies for both the intermediate conveying devices 3 and 4.

Next, to explain its effect, as the aircraft advances, the grain culms planted in the field lift the device 1.
3, and after the root of the crop is harvested by the reaping device, the harvested grain culm is taken over by the two intermediate conveying devices 3 and 4, and the root of the crop is transferred to the clamping and conveying device. 3 is held from the left and right, and
The tip portion is transported from the front to the rear in a substantially upright state with the tip portion latched to the transport device 4. During this conveying action, the tip side of the harvested grain culm, which is in an approximately upright position, is gradually brought down and changed to an approximately recumbent threshing position, and then the stock base is placed on the side of the clamping and conveying device 17 of the threshing device 2, and
The tips of the ears are transferred into the threshing chamber 2a through the supply opening 8 and are then threshed as they are conveyed to the rear of the stock head with their clamps. The grain culm is transferred from the terminal end of the intermediate clamping and transporting device 3 that grips and transports the stock head of the harvested grain culm from the left and right to the starting end of the clamping and transporting device 17 that clamps and transports the stock head from above and below on the threshing device 2 side. When inheriting the stock part, the stock part of the grain culm, which is released from the clamping and conveying device 3 on the upper side of the conveyance and sent out, is moved to the single grain culm pinning guide rod 1 extending from the fixed frame 3a.
