Description

[Detailed Description of the Invention] The present invention relates to a crop storage device for storing root vegetables such as potatoes and onions on the ground or underground in a container provided on a harvester without damaging them.

Conventionally known root crops such as potatoes and onions are dumped by a harvester and placed in a container, bag, tank, etc. supported by an L-shaped pedestal by a feeding conveyor. We are investing.

For example, in the conventional example shown in FIG. 4, a container 3 for storing root vegetables 30, 30, ... to be harvested.
No. 1 has a configuration that allows movement only in the vertical direction.

That is, an L-shaped pedestal 34 is configured to be movable up and down on a support 33 provided at the rear end of the body 32, and the container 31 is placed on this pedestal 34.

Therefore, the root vegetables 30 supplied from the feed conveyor 35 have a large head difference h between the discharge point at the rear end of the conveyor 35 and the fall point to the bottom of the container 31, and the root vegetables 30 are Mutual collisions may damage root vegetables, which has the disadvantage of lowering their commercial value and reducing profits during harvest.

On the other hand, in a transport device for agricultural products installed at a predetermined location, a device is already known that supports a storage container in a slidable manner in order to smoothly and easily store the agricultural products (for example, Japanese Patent Publication No. 55-30323). However, in the above-mentioned apparatus, since the container stores agricultural products at a predetermined location, there is no need to raise and lower the container, and therefore, there is no mechanism for raising and lowering the container.

The present inventor considered combining the above-mentioned conventional techniques and incorporating this into a movable root vegetable harvester. That is, the present invention reduces damage to root vegetables during harvesting by attaching a device to a movable root vegetable harvesting machine that supports a container for storing root vegetables in a manner that allows it to be raised, lowered, and tilted. To provide a crop storage device that allows containers to be easily and quickly loaded and unloaded from a machine.

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

FIG. 1 is a side view of the entire root vegetable harvesting machine. The figure shows a dumping device 1 that digs up root vegetables in a field and throws them away, or throws up the dug up root vegetables and transports them to the rear, and the root vegetables supplied from this dumping device 1. 2, a sorting device 3 for sorting out foreign objects such as stones and wood chips, defective crops, etc.;
A feed conveyor device 5 that conveys the sorted root vegetables 2 to a rear collecting section 4 is connected to a machine body 6 equipped with a sequentially traveling crawler 7, and the root vegetables 2 in the field are continuously harvested and collected. This constitutes Harvest 8.

As shown in FIGS. 2 and 3, the collecting section 4 includes a support 10 having a groove in which the cross roller 9 is inserted.
is installed at the rear end of the fuselage 7 in an upright manner.

The roller mast 11 is attached to the support column 10 by cross rollers 9 so as to be able to move up and down in the vertical direction. It is configured so that it can be raised and lowered in the vertical direction by an actuator 13.

Further, support arms 14, 14 are fixed to the left and right upper ends of the roller mast 11.
A pair of L-shaped pedestals 16, 16 for supporting a container 15 for storing root vegetables 2 are rotatably attached to the upper ends of the vertical sides of the pedestals 4, 14 by means of a support shaft 17. At the upper left and right ends of the pedestal 16, there are rotating arms 1.
8 and 18 are fixed, and there is a hole 1 in each tip.
9 is formed, and actuators 20, 20, which are rotatably supported at the lower part of the roller mast 11 and capable of reciprocating movement, are connected to this with pins 21, 21, etc.

The actuators 20, 20 are shown using hydraulic cylinders, but may be other electric mechanisms capable of reciprocating motion, such as a swing motor or an electric cylinder. Further, the actuator 20 is configured to be controllable from a driving operation section or any other arbitrary position.

Next, the function of storing root vegetables 2 in the container 15 of this invention will be explained.

Place the empty container 15 on the pedestal 16, operate the actuator 13 that raises and lowers the roller mast 11 in the vertical direction, and raise it. Next, actuate the actuators 20, 20 to raise the pedestal 16. It is tilted close to the feed conveyor device 5.

In this way, the head H by which the root vegetables 2 discharged from the feed conveyor device 5 fall becomes smaller. As the amount of root vegetables 2 stored in the container 15 increases, the head H becomes smaller, so the actuators 20, 20 are operated by the control device to always maintain a constant distance. Therefore, damage to the stored root vegetables 2 is extremely reduced, and a decrease in commercial value can be prevented. When the container 15 is full of root vegetables 2, the harvesting operation is stopped, the root vegetable harvester 8 is moved back a little, and the pedestal 16 is lowered to place the full container 15 on the ground. Next, the root vegetable harvesting machine 8 is moved forward, and the empty container 15 is placed on the pedestal 16 by the forklift that has previously carried the empty container 15. Furthermore, the container 15 filled with crops is transported to a predetermined position by a forklift.

According to the present invention, there are the following effects. That is,
In a root vegetable harvesting machine 8 that moves through the field with a traveling crawler 6 and collects and stores root vegetables, the pedestal on which the container is placed can be rotated and tilted close to the feed conveyor 5, so that the feed conveyor device 5 This reduces the head of the root vegetables when they are discharged into the container 15, and the slope of the container 15 can be maintained at an appropriate inclination in response to the increase in the amount of harvested crops, thereby preventing damage to the root vegetables. This has a great practical effect of reducing the loss of profits during harvesting.
