Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to an improvement of a thrower's grain lifting cylinder.

[Conventional technology]

For example, it is common practice to install a thrower on one side of the bottom of a grain tank mounted on the combine main body or on one side of another grain container, and to use the thrower to transfer the grains in the tank or container to another. It is being said. For this purpose, the tip of the grain lifting cylinder of this type of thrower is equipped with an arcuate curved ejector with an ejection port facing downward to accurately transfer the grains to other storage bodies. At the same time, the upper part of the grain lifting cylinder including the curved ejector is rotatable relative to the thrower main body, so that the ejecting direction can be adjusted. This type of device is equipped with a rotating lever at the bottom of the rotating grain lifting cylinder, and by operating this rotating lever, the rotation of the grain lifting cylinder, more specifically, the ejection direction of the curved ejector can be changed. This is what I used to do. However, as shown in Figure 1, the grain harvested and threshed by a combine harvester is stored in a grain tank, and when this tank is full, the combine harvester is moved to a predetermined location and the grain is removed from the road near the field. When transferring grain from a tank to a grain container mounted on the platform of a transport vehicle, such as a truck, which is parked at It is necessary to operate the rotating lever to change the direction of grain release. In other words, there is a problem in that the operator (driver) must change the discharge direction while going back and forth between the loading platform of the transport vehicle and the combine harvester.

Also known is a thrower in which a curved ejector can be independently rotated at the tip of the thrower. There is a device in which the swinging motion of this curved projector is performed using a rope or wire mechanism that can be operated on the ground, but in this device, as well as in the above-mentioned conventional example, the operator can move the swing between the truck loading platform and the combine harvester. There is an operational problem in that the direction of discharge must be changed while reciprocating.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and it solves the problems of the conventional technology by simple and rational means. This allows the worker to independently adjust the swing of the curved ejector on the spot while visually checking the grain release and supply status on the loading platform, reducing the worker's labor and increasing the accuracy of the ejecting direction. It is an object of the present invention to provide a thrower grain lifting cylinder which can improve the efficiency of grain throwing.

[Means for solving problems]

The thrower grain lifting cylinder of the present invention, which solves the problems of the prior art, is provided with an arcuate curved ejector at the tip of the thrower's grain lifting cylinder, and rotates a part of the grain lifting cylinder including the curved ejector. In the thrower that can change the direction of grain discharge by moving, the curved ejector is rotatably attached to the upper end of the rotating grain lifting cylinder, and the grain lifting cylinder is rotated. The present invention is characterized in that mechanisms are provided at a plurality of locations on the rotary grain lifting cylinder, including at least the base of the curved ejector.

And this lower grain lifting cylinder 2a
The upper grain lifting cylinder 2b is rotatable relative to the upper grain lifting cylinder 2b. The coupling and rotation means for the upper and lower grain lifting tubes 2a, 2b are constructed as follows.

That is, a reinforcing tube 4 having an outward flange 4a is attached to the outer periphery of the upper end of the lower grain lifting tube 2a. Further, an outward flange 2c is provided at the lower end of the upper grain lifting cylinder 2b.

The lower part of the upper grain lifting cylinder 2b surrounded by the bending metal 6 and the guide cylinder 5 is rotatably supported with the required sliding resistance against the bending metal 6 and the guide cylinder 5. be done. One side of the bending metal 6 and the stays 7 and 8 provided on the reinforcing tube 4 are connected by a shaft 9, and the grain lifting tube 2 can be bent with the lower surface of the bending metal 6 and the upper surface of the reinforcing tube 4 as boundaries. So,
The upper grain lifting cylinder 2b is folded and accommodated. Reference numeral 10 denotes an L-shaped fixing fitting that is attached to the guide tube flange 5a on the bending metal 6 and penetrates through the bending metal 6, and the vertical side of the fixing fitting 10 is provided on the flange 4a of the reinforcing tube 4. Notch 1

〔effect〕

As described above, according to the present invention, for example, the thrower having the grain lifting cylinder of the present invention is attached to a grain tank mounted on a combine harvester as shown in Fig. 1, and this thrower is used to lift grains in the grain tank. When transferring and supplying grain to a grain container mounted on the platform of a transport vehicle parked on a road close to the field, if the direction of grain release is changed depending on the site situation and grain transport conditions, Not only can you change the direction of grain discharge by operating the rotation control lever, but you can also change the direction of grain discharge by climbing up onto the carrier's platform and visually checking the status of the grain stored in the grain container. Sometimes, the release direction can be changed by manually operating the operating section at the base of the curved ejector directly from the loading platform, without having to go down to the ground and go to the combine harvester as in the past. Therefore, compared to the prior art, this method not only saves the labor of the operator, but also has great practical effects, such as transporting grains under the best conditions.
