Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a harvester, and more specifically, the present invention is related to a harvester, and more specifically, a grain culm is supplied to a threshing device by conveying a placed grain culm bundle in a substantially horizontal direction orthogonal to the culm body. The present invention relates to a harvester equipped with a grain feeding device for feeding grain to the mouth.

[Conventional technology]

The technique of providing a grain culm supply device as described above in the front part of the grain culm supply port of the threshing device is often seen in stationary threshing machines, and an example thereof is shown in Japanese Utility Model Publication No. 45-20528. It is known that a grain culm feeding device is constructed by providing a grain culm transfer spiral on a grain culm feeding table and also having an endless belt for feeding the grain culm transferred by the spiral into the threshing device entrance. .

[Problem that the invention attempts to solve]

Since the above-mentioned grain culm feeding device is arranged to protrude greatly from the threshing device, if it is installed in a harvester, it will be difficult or impossible to move it through the narrow passage between the grain culm drying frame and one pile. It was expected that this would result in a large amount of damage, and it was not possible to immediately apply it to harvesters.

In addition, in threshing work using a harvester,
Depending on the variety of the crop, it may be necessary to carefully handle and feed each bundle individually, but if the above-mentioned grain culm feeding device is installed, the grain culms will get caught in the endless transport belt in front of the threshing device entrance, creating resistance and causing the grain to burp. This hinders manual supply.

An object of the present invention is to provide a harvester with a grain culm feeding device that can be conveniently used without causing the above-mentioned problems.

[Means for solving problems]

The harvester according to the present invention is a harvester having the above configuration, in which the grain culm feeding device is divided into an upper part and a lower part in the middle, and is configured to be bendable at the divided part, and further, the upper part The present invention is characterized in that it is provided with an endless conveying belt that locks and conveys the grain culm bundles in the substantially horizontal direction.

[Effect]

When the grain culm supply device is extended almost horizontally and the grain culm bundles are arranged on the device, the grain culm bundles are pushed forward by the conveying force of the endless conveying belt and the grain culm bundles are placed on the lower side. The grains are fed to the threshing equipment in order. In this case, if the conveyance resistance at the lower part of the grain culm feeder is large, the upper part of the grain culm feeder can be adjusted slightly upward, and the lower part can be tilted backward and downward. It can be fed smoothly into the mouth.

In addition, when moving through narrow passages between frames or between piles, by bending the grain feeder, supporting its upper part almost horizontally in an upward position, and tilting its lower part, Reduce the lateral protrusion of the device. In this case, the grain culm bundle is simply placed on the upper part and transported to the lower side by the endless transport belt provided there, and when it reaches the lower part, it slides down the slope naturally. Then, the grain is fed into the grain supply port of the threshing equipment.

Also, when moving through particularly narrow passages, the upper part of the grain feeder may be folded downward or upward relative to the lower part. However, in this case, the grain culm will be placed on the lower part and handled and fed by hand.

Furthermore, even when the grain culm feeding device is in a horizontally extended state, it is possible to carefully handle and feed one bundle at a time by using the lower part without the endless conveying belt as a feeding stand, as in the past.

[Effect of idea]

As explained above, according to the present invention, by constructing the stalk supplying device so that it can be freely bent, it is possible to move freely through the narrow passages between the racks or single stakes to perform threshing work.

In addition, since the lower part of the grain culm feeding device does not have an endless transport belt, manual feeding can be carried out as before without being hindered by the endless belt.
It is useful in practice.

〔Example〕

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

As shown in Figure 4, crawler running vehicle body 1
An engine 2 and a threshing device A are mounted on the vehicle body 1, and a driving section 3 is formed at the end of the vehicle body 1 to constitute a harvester.

The driving section 3 is provided with a traveling clutch lever 5 projecting from the bonnet 4 covering the engine 2, a pair of left and right side clutch levers 6, 6, a speed change lever 7, etc., and the threshing device A.
A grain culm supply port 8 is formed on the side surface of the vehicle body 1, and a handling port 9 is formed on the rear surface of the device A. By supplying the grains, the grains are threshed by the lower-handling type handling cylinder 11 and the sorted grains can be collected through the grain lifting cylinder 12.

In addition, the harvester is configured so that the grain stalk bundle K is automatically fed by the grain stalk supply device 13,
The grain straw bundle K placed on the grain straw supplying device 13 is
The stalks are transported in a substantially horizontal direction perpendicular to the stalks and supplied to the stalk supply port 8 of the threshing device A.

To explain the grain culm feeding device 13 in detail, as shown in FIGS. 1 and 2, the device 13 is divided into an upper portion 13A and a lower portion 13B in the middle, and is bent at the divided portion. It is freely configured. Two rows of long grooves 13a are formed in the longitudinal direction of the upper portion 13A, and in each of the long grooves 13a, an endless conveying belt 14 consisting of a chain with claws is placed with the claws protruding upward. The grain culm bundle K is secured and conveyed by the protruding pawl. Incidentally, the turning drive is performed by the drive shaft 1 of the endless belt 14 with respect to the counter shaft 15 chain-linked with the rotating shaft 10a of the feed chain 10.
4a are carried out in a chain-linked manner.

Further, rods 13C and 13D are pivotally connected to the lower portions of the upper portion 13A and lower portion 13B of the grain culm feeding device 13 divided as described above, and the lower end of the rod 13C on the upper portion 13A side. are slidably connected along the rod 13D on the lower portion 13B side, and these rods 1
The grain culm feeding device 13 using 3C and 13D,
The upper portion 13A and the lower portion 13B are bent at the dividing portion, so that the upper portion 13A can be maintained in a substantially horizontal state.

Further, the feed chain 10 is attached with a feed chain cover 10A that covers it from above, and a spring 16 is provided on the cover 10A to constantly bias the feed chain 10 toward the upper side. A guide rod 17 is slidably provided, and when the grain culm feeding device 13 is in the feeding position (see FIG. 1), the guide rod 17 is moved by the spring 16 to the feed chain 10.
While the grain culm feeding device 13 is slid upward and protrudes from the cover 10A, it is possible to prevent the grain culm bundle K from getting caught in the cover 10A. In this state (see FIG. 3), the feeding device 13 causes the guide rod 17 to slide toward the downstream side of the feed chain 10 against the elastic force of the spring 16. In this stored state, the hook-shaped tip of the rod-shaped body 18 to which the supply device 13 is attached is configured to be hooked on a U-shaped grooved hook 19 attached to the chain cover 10A, This allows the supply device 13 to be maintained in its stored position.

In the harvester having such a configuration, the grain culm feeding device 13 is located midway through the upper portion 13A and the lower portion 13.
Since the grain culm feeding device 13 is foldably divided into B and B, the amount of protrusion of the grain culm feeding device 13 to the side of the machine body can be reduced by bending the split portion. Further, if the grain culm feeding device 13 is bent as described above, and its upper portion 13A is supported in an upper position substantially horizontally, and its lower portion 13B is inclined, the grain culm bundle K is Just by placing the grain on the portion 13A, it is stopped and conveyed to the lower side by the endless conveying belt 14 provided there, and when it reaches the lower portion 13B, it slides down the slope and naturally passes through the grain culm of the threshing device A. It comes to be fed into the supply port 8.

Further, the upper portion 13A and the lower portion 13B are set in a series of horizontal positions, and the grain culm bundle K placed on the lower portion 13B is pressed by the grain culm bundle K conveyed by the endless conveying belt 14. It is also possible to feed the feed chain 10 sequentially.

Also, the upper part 13A is in a horizontal position than the lower part 13
It is also possible to bend the protrusion downward (or upward) at a substantially right angle with respect to B to further reduce the amount of protrusion.
