Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain culm pincher transfer device for transporting grain culms along the handling drum of an upper handling type threshing machine.

In the grain culm pinching transfer device of the top handling type threshing machine,
In the Showa era, the feed chain and the clamping rod for holding the grain culm were disposed so that the feed chain was located below the clamping rod, and the clamping rod had a downward U-shaped cross section. It is known from 1941 Utility Model Application Publication No. 10195 and Japanese Patent Publication No. 32-7716.

However, in both of these publications, the inner vertical plate on the side closer to the handling chamber among the left and right vertical plates of the clamping rod having a downward U-shaped cross section is located between the left and right link plates of the feed chain, and the clamping rod has a downward U-shaped cross section. Of both vertical plates in the rod, the outer vertical plate on the far side from the handling chamber is located outside of the outer link plate of both link plates in the feed chain, which is on the outside with respect to the handling chamber. because there is,
The grain culm sandwiched between the feed chain and the clamping rod is connected to the inner link plate of the feed chain located below the grain culm, and the clamping plate located above the grain culm and between both link plates of the feed chain. By being held between the inner vertical plate of the rod, the tip of the grain bends upward, in other words, the tip of the grain culm is connected to the inner link plate of the feed chain at the base of the grain culm and the inner vertical plate of the clamping rod. Due to the clamping between the feed chain and the clamping rod, the grain tends to lift up from the handling barrel, so the threshing action of the tip of the grain by the handling barrel is weak and the grain tends to be left untreated. Since the bend is directed upward, the grain culm is easily pulled out of the grain culm pinching transfer device by the rotation of the handling cylinder when threshing the grain culm.

The present invention solves the drawbacks of the grain culm pinching and transferring device of the conventional top-handling threshing machine.

For this reason, the present invention provides a grain culm pinching transfer device installed outside a handling chamber containing an upper handling type handling cylinder so as to transfer the grain culm along the axial direction of the handling cylinder. It consists of a clamping rod installed along the
The feed chain is disposed below the clamping rod, and the clamping rod is formed into a downward U-shaped cross section, and one of the left and right vertical plates of the clamping rod is placed on the outside with respect to the handling chamber. between the left and right link plates in the feed chain; located respectively in
Further, the lower end edge of the inner vertical plate of the clamping rod is configured to protrude further downward than the lower end edge of the outer vertical plate.

That is, with this configuration, the grain culm being transferred is transferred between the inner link plate of the feed chain located below the grain culm and the inner side of the pincer rod located above the grain culm and inside the inner link plate of the feed chain. Due to the pinching with the vertical plate, the tip part is bent downward in the direction of being pressed against the handling barrel, and the lower edge of the inner vertical plate of the clamping rod is protruded below the lower edge of the outer vertical plate. The tip of the grain is further pushed down by the inner vertical plate of the clamping rod and is pressed more strongly against the handling barrel. If the tip of the grain culm were to press strongly against the handling drum,
Not only can unhandled grains be prevented, but also the amount of grain culms being pulled out due to the rotation of the handling cylinder can be reduced.

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

A receiving net 2 is stretched over the lower part of a handling drum 1 that is pivoted in a handling chamber 22 and rotates in the direction of arrow A, and a swinging transfer plate 4 is oscillated below the receiving net 2 via a grain distribution plate 3. It is freely installed, and a sieve net 5 is provided at the tip of the swinging transfer plate 4. A winnow 6 is provided further below the swinging transfer plate 4, and a sorting pattern 7 is formed extending from the tip of the swinging transfer plate 4 to the dust exhaust pipe 8.

Further, a first grain conveyor 9 and a receiving trough 10 are provided at the bottom of the sieve net 5, and the transfer end thereof is communicated with the first grain lifting machine 11 consisting of a grain frying fan 11' and a grain frying tube 11''. This first grain lifting machine 11 is installed on the outside of the machine wall a on the opposite side to a grain culm pinching transfer device 12, which will be described later.

Reference numeral 15 denotes a stalk for preventing grain removal, which is shaped like a fork in order to swing and sift out grains, cut ears, etc. in the threshed culm. The grain grain removal prevention rod 1
At the lower part of the grain culm 5, an inclined guide plate 17 is disposed obliquely to allow the grains, cut ears, etc. to flow down to the sieve line 16, and a No. 4 funnel 23 is formed at the rear of the handling chamber 22. The device 12 is configured to transfer grain stems from the left supply port 21 in the handling chamber 22 and into the handling chamber 22 and to the rear thereof through the No. 4 funnel 23.

Further, below the sieve line 16, a second grain conveyor 18 and a second receiving gutter 19 are provided perpendicularly to the grain culm pincher transfer device 12 and the grain rack 7, and the terminal end thereof is connected to a second grain lifting fan 20. ' and a second reducing cylinder 20''.The second grain lifting machine 20 is connected to the grain culm pinching transfer device 1.
It is installed on the outside of the machine wall b on the second side, and the upper end opening of the second reducing cylinder 20'' is connected to the grain culm pinching transfer device 12.
It looks into the handling room 22 below.

The grain culm clamp transfer device 12 includes an endless feed chain 13 and a clamp rod 14 provided along the feed chain 13, and rotates the grain culm in the direction of arrow A as shown in FIG. Handling trunk 1
The feed chain 13 of the grain culm clamping transfer device 12 is positioned below the clamping rod 14, and The rod 14 is formed into a downward U-shaped cross section, and the outer vertical plate 14a of the left and right vertical plates 14a and 14b of the rod 14, which is the one farthest from the handling chamber 22, is connected to the left and right sides of the feed chain 13. The inner vertical plate 14b, which is located between the link plates 13a and 13b and which is closer to the handling chamber 22 among the left and right vertical plates 14a and 14b of the clamping rod 14, is the left and right link plate 13a of the feed chain 13, 13b, the inner vertical plate 14b of the clamping rod 14 has a lower end protruding below the lower end edge of the outer vertical plate 14a.

In this configuration, the grain is fed between the feed chain 13 and the pinch rod 14 in the grain culm transfer device 12 on the left supply port 21 side of the handling chamber 22 by a suitable grain transfer device (not shown). The culm is held between the feed chain 13 and the clamping rod 14 and is sequentially transferred to the right side to the handling cylinder 1.
After threshing, the grain is discharged outside the machine through the No. 4 funnel 23.

When the grain culm is pinched and transferred by the feed chain 13 and the pinch rod 14 in the grain culm pinching transfer device 12, the grain culm being transferred is moved by the inner link plate 13b of the feed chain 13 located below the grain culm.
and a pinching rod 1 located above the grain culm and inside the inner link plate 13b of the feed chain 13.
By holding the inner vertical plate 14b of the clamping rod 14 with the inner vertical plate 14b, the tip part is bent in the direction of being pressed against the handling barrel 1 as shown in FIG. By protruding downward from 14a, the tip of the spike becomes a pinched rod 14.
The inner vertical plate 14b is bent so that it is pressed more strongly against the handling cylinder.

An embodiment of the present invention is as described above,
The gist of the present invention is the configuration described in the claims, and with this configuration, the tip of the grain culm held between the feed chain and the clamping rod in the grain culm clamping transfer device is strong against the handling barrel. Because it can be pressed, when threshing with the handling barrel, it is possible to reliably thresh even the ears of grain near the stock head, and the amount of unhandled grain can be significantly reduced. By bending downward due to the clamping between the feed chain and the clamping rod in the transfer device, the clamping becomes even stronger, reducing the need to pull out the grain culm during threshing.
This has the effect of reliably preventing overload on the handling drum and defective threshing that occurs when the grain culm is pulled out by the handling drum.
