Description

[Detailed description of the invention] [Industrial application field] The present invention mainly relates to a threshing machine mounted on a harvester, and more specifically, it transports the grain culm placed therein in a direction perpendicular to the culm body and threshes the grain. The present invention relates to a threshing machine that includes a supply conveyance device that supplies grain toward a grain supply port of the device and is interlocked and connected to the threshing device.

PRIOR ART

As shown in Japanese Utility Model Publication No. 45-20528, the conventional threshing machine is equipped with a conveying screw interlocked with a threshing device on a grain culm supply stand on which grain culms are placed, and a supply and conveyance device. There is something that consists of

[Problems to be solved by the invention] However, in the conventional structure described above, when it is necessary to temporarily feed grain culms manually during grain culm supply and transportation work, the placed grain culms cannot be moved. After all of the grain culms have been removed, the grain culms that are to be threshed out of the grain culms placed elsewhere must be manually transported and fed into the threshing device, resulting in poor work efficiency.

As a way to solve the above problem, it is possible to install a dedicated clutch between the supply conveyance device and the threshing device to stop the feed conveyance device, but if the stopped supply conveyance device manually supplies grain culms, Expect it to get in the way.

The present invention solves the above problems and provides a threshing machine that has a simple structure and enables manual threshing with the grain culm placed on the feed conveyance device without stopping the feed conveyance device. The purpose is to

[Means for solving problems]

The characteristic structure of the present invention for achieving the above object is to transport the loaded grain culm in a direction perpendicular to the culm body, and to supply the supply conveyance device toward the grain culm supply port of the threshing device. A threshing machine that is interlocked and connected to a device, wherein the grain culm conveyance state is such that the conveyance action section of the supply conveyance device acts on the placed grain culm, and the upper end edge of the guide member provided on the side of the conveyance action section. The feeding and conveying device and the guide member are configured so that their relative heights can be changed so that the grain culm receiving posture can be switched to a grain culm receiving posture located above the conveying action section, and its functions and effects are as follows. That's right.

[Effect]

According to the above configuration, when the guide member is switched to the grain culm receiving posture in which the upper edge thereof is located above the conveyance action part, the grain culm is received and supported by the guide member without being subjected to the conveyance action of the supply conveyance device. This allows for manual feeding by sliding it on this guide member.

〔effect〕

Therefore, it has become possible to easily perform careful manual threshing while placing the grain culm above the supply conveyance device without stopping the threshing device and the endless rotating belt.

〔Example〕

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

FIG. 7 shows a harvester (mobile threshing machine) as an example of a threshing machine according to the present invention. This harvester has a threshing device 2 removably mounted on the fuselage frame 1.

At the rear end of the threshing device 2, a feed chain 9 is installed extending in the left-right direction of the machine, and the stock side of the grain culm is held between the feed chain 9 and a holding rail 10 along the lower side. While the grain is being transported from the left side to the right side of the threshing device 2, the kernels on the ear side are handled by a handling cylinder 11.

The feed chain 9 is wound around a drive sprocket 12a on the right side of the machine body and a driven sprocket 12b on the left side, and is configured so that the rotational power of the engine 3 is transmitted to the drive sprocket 12a. The rotating shaft 13 of the driven sprocket 12b extends forward, and the rotating shaft 13 of the driven sprocket 12b extends forward.
3 is configured to be transmitted to the supply conveyance device 7 via a chain type transmission mechanism 15.

As shown in FIGS. 1 and 2, the feeding and conveying device 7 includes a grain culm supply stand 18 having a width sufficient to receive and support the grain culm bundles placed thereon over almost the entire length.
Two endless rotating bands 20, 20 each having a plurality of protrusions 19 are stretched in the left-right direction at a predetermined interval.

That is, the endless rotating bands 20, 20 are connected to the drive side sprocket 23, which is attached to the output shaft 22 of the chain type transmission mechanism 15, which extends in the front-rear direction.
23 and the driven sprockets 24, 24 on the free end side, power is transmitted as described above, and the endless rotating bands 20, 20 are rotationally driven.
The placed grain culm is conveyed in a substantially horizontal direction perpendicular to the culm body, and is configured to be supplied toward the grain culm supply port 14 of the threshing device 2.

The supply conveyance device 7 is configured to be able to swing around the axis P of the output shaft 22, and includes a holding mechanism 26 that can be slidably fixed to a support frame 25 fixed to the threshing device 2, and a holding mechanism 26. The support arm 27 is pivotally connected to the support arm 26, so that it can be switched and fixed between a substantially horizontal conveyance state and a vertical storage state.

The power of the output shaft 22 is configured to rotationally drive an auxiliary conveying device 28 that locks and conveys the stock side of the grain culm from the terminal end of the supply conveying device 7 toward the starting end side of the feed chain 9. There is.

As shown in FIGS. 1 to 4, guide members 29 are provided on both sides of each of the endless rotating bands 20, 20, and extend toward the conveyance direction.
This guide member 29 has an upper edge 30 that is connected to the endless rotation band 2.
It is configured to be switchable between a conveying state position in which the upper end edge 30 is located below the protrusion 19 serving as a conveying action portion of 0 and 20, and a receiving position in which the upper edge 30 is located above the protrusion 19.

That is, each guide member 29 has a swing arm 31, 3 whose one end is pivotally supported on the grain culm supply table 18.
1, and a toggle spring 32 is stretched between a locking point A at an intermediate position of each of the swing arms 31, 31 and a locking point B of the grain culm supply table 18. be. When the locking point A is below the imaginary line S connecting the locking point B and the swinging fulcrum X of the swinging arms 31, 31, the guide member 29
The lower end edge 33 is in contact with the grain culm supply table 18 and the upper end edge 30 is fixed below the protrusion 19, and the grain is The culm is supplied and transported.

Then, when the guide member 29 is manually raised against the tensile force of the toggle spring 32, the locking point A
When is above the imaginary line S, the swing arm 3
1 and 31 swing upward due to the tensile force of the toggle spring 32, and further swinging is prevented by the locking portion 34, so that the upper end edge 30 is fixed in a state located above the protrusion 19. Then, the grain culm is received by the guide member 29, the endless rotating belt 20 does not act, and the supply to the threshing device 2 is stopped.

[Another embodiment] As shown in FIG. 8, the guide member 29 is
The grain culm supply stand 18 may be provided removably, and may be fitted and fixed into the fitting hole 35 of the grain culm supply stand 18.

The guide member 29 is configured such that the grain culm supply table 18 can be raised and lowered with respect to the endless rotating belt 20 without being provided separately from the grain culm supply table 18.
9 may also be used.

The supplying and conveying device 7 may use a screw instead of an endless rotating band with protrusions.
