Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a culm conveying device in a combine harvester, and particularly to a tip conveying device.

A vertical conveying device is provided for horizontally conveying the stock base and tip of the culm cut by the harvesting section of the combine using a plurality of horizontal conveying devices, and then vertically conveying them separately.

It is known that the grain is supplied to the threshing section.

In this case, the end of the transport of the horizontal transport device and the start of the vertical transport device are placed close to each other to make it easier to transfer the culms, but the arrangement of the devices and the method of power transmission vary. This causes a shift in the feed and also makes the mechanism complicated.

This tendency becomes particularly strong when the tip portion is transported horizontally by two horizontal transport devices, merged into one, and transported vertically by a vertical transport device.

Therefore, the present invention enables smooth transfer from the horizontal conveyance device to the vertical conveyance device without causing any deviation even in the above-mentioned cases, and enables smooth transfer even when the shell culm is short. Another object of the present invention is to provide a shell culm conveying device for a vine combine with a simplified transmission mechanism.

In order to achieve this purpose, the device of the present invention is installed in such a way that the starting end of the vertical conveying device is sandwiched between the conveying end portions of the upper and lower sets of the tip horizontal conveying devices, and from the vertical conveying device to the both horizontal conveying devices. It is characterized by transmitting power to.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, symbol 1 is the combine main body, and this main body 1
, a traveling device 2 is attached, a reaping section 3 is mounted on the front part, and a threshing section 4 is mounted on the rear thereof. A reaping device 6 is provided at the rear of the lower part.

Further, the culm, which is located behind the culm pulling device 5 and above the reaping device 6, is harvested by the reaping device. A shell culm conveying device T is provided for conveying the husks so as to feed them to the handling ports of the threshing section.

The shell culm conveying device 7 includes a stock base horizontal conveyor 8 that transports the base of the shell culm to the machine body side (the above-mentioned foot chain 4a side), and a stock base horizontal conveyor 8 that conveys the base of the shell culm to the body side (the above-mentioned foot chain 4a side), and a vertical conveyor that takes over from the conveying end of this horizontal conveyor 8. a vertical conveyor body 9 for conveying and supplying the foot chain 4a;
The tip of the culm.

The upper tip lateral conveyor 10 and the lower tip lateral conveyor 11, which are transferred to the handling port side in synchronization with the conveyance of the stock part, merge the tip parts conveyed by the lateral conveyors 10 and 11 and move them vertically. It is composed of a vertical tip portion conveying body 12 for conveying.

The conveyance start end side of the tip vertical conveyor 12 is superimposed between the conveyance end sides of the tip upper horizontal conveyor 10 and the lower tip horizontal conveyor 11.

The tip vertical conveyor 12 receives power from one end (not shown) and rotates an idle sprocket wheel 12b via a chain 12a. This transport lug 12
c can be pushed out and retracted from the case 12d.

Further, the rotation shaft 12e of the sprocket wheel 12b is
It protrudes from the case 12d, and the drive sprocket wheel 10a of the tip upper lateral conveyor 10 is fixed to the tip thereof.

Similarly to the vertical conveyance body 12, the tip upper horizontal conveyance body 10 also winds a Nichen 10c between it and the idle sprocket wheel 10b, and conveys lugs 10d, 10d, etc. around this chain 710c.
・This is installed so that it can be pushed out and retracted from the case 10e.

Furthermore, the tip lower horizontal conveyor 11 is attached to the side opposite to the horizontal conveyor 100 of the case 12d of the vertical conveyor 12, and the rotation axis 11b of the driving side sprocket wheel 11a is connected to the vertical conveyor 120 in the case 12d. The above rotating shaft 12e
The sprocket wheel 11c is fixed thereto so as to mesh with the chain 712a, and power is transmitted thereto.

Also in the lower horizontal conveyor 11, the sprocket wheel 11a*
The conveyor lugs 11f and 1 are attached to the chain 711e wound around the
1f... is pivotally mounted so that it can be pushed out and retracted from the case 11g.

Note that the length of the transport lug 12c of the vertical transport body 12 is longer than that of the transport lugs 10d and 11f of the horizontal transport member 10.11.
Also, set the interval widely.

According to such a configuration, the combine introduced into the field, while traveling by the traveling device 2, raises the erect culm by the culm pulling device 5 and reaps the lower part of the culm by the reaping device 6.

The stem part of the cut culm is transferred to the vertical conveyor 9 by the horizontal conveyor 8.
It is transported to the side, taken over by the vertical transport body 9, lifted up, and supplied to the foot chain 4a.

In addition, as the tip of the culm is transported, the upper and lower horizontal conveyors 10 and 11 transport it to the handling port side of the threshing section 4, and then it is taken over by the vertical conveyor 12 and lifted up. As soon as the grains begin to be transported by the foot chain 4a, they are introduced into the handling chamber through the handling port and are threshed.

At this time, the upper and lower sets of the tip horizontal conveyors 10.11 are sprocket wheels 12b, 12c, which are rotated by the deen 12a of the vertical conveyor 12 located between these, respectively.
A drive side sprocket wheel 10d is fixed to the rotating shafts 12e and 11b.

11d, Che 710c suspended on these respectively.
, 11e, etc., so both.

The power is transmitted from the vertical conveyance body 12, and therefore the conveyance lugs 10d and 11f, which are pivotally connected to the chess 710c and 11e, respectively, and the conveyor lug 12c, which is pivotally connected to the chain 12a, are both In addition to rotating synchronously, the culm, which has been gripped at the top and bottom of the tip by the lugs 10d and 11f of the horizontal transport body 10. 12c, the sprocket wheel lla at one end of the tip horizontal conveyance body 10.11 is held at the starting end of the tip vertical conveyance body 12. The sprocket wheel 12b is disposed behind the sprocket wheel 12b, and is disposed at a position shifted from the end of the other lateral conveyor 10, so that the tip of the sprocket wheel 12b is disposed at a position shifted from the end of the other lateral conveyor 10.

This is to prevent it from getting caught in the horizontal conveyor.

The above-mentioned transfer is carried out even more smoothly and reliably, and the power transmission mechanism to the upper and lower set of tip section lateral conveying bodies 10.11 is as follows.
It is located between these carriers.

Moreover, the tip vertical conveyor 12 approaches the combine main body.
Since it is carried out from the side, the structure is simple and compact.Moreover, even with short culms, the tip is pivoted by two upper and lower tiers of tip transverse conveyors, making it smooth and reliable in both the lateral and longitudinal directions. will be transferred to.

As described above, according to the conveying device of the present invention, the tip portion is conveyed horizontally by the two horizontal conveying bodies, and the tips are joined together and reliably connected to the vertical conveying body without being caught in the horizontal conveying body. In addition, the power transmission is simplified and at the same time ensures the connection between both devices, and has the effect of smoothly transferring even short culms without causing displacement of the seed part of the culm. be.
