This invention relates to a device for digging up spheres, which enables the harvesting of even row stocks with power equipment, and also enables harvesting of inner row stocks adjacent to the outermost row at the same time.

[Technical background] When harvesting is carried out in a vast field using large-scale mobile power equipment, it is impossible to harvest only the outermost rows of plants on the periphery of the field due to the structure of the power equipment used. As a result, these tasks had to be carried out individually by hand.

[Conventional technology] Power equipment for harvesting spheres in vast fields is
Many of them are not directly equipped with a power source, and are therefore pulled by a working power vehicle such as a tractor, and work with power supplied to them.
Examples include the ``wasabi harvester'' seen in Publication No. 15285. In addition, there are also ideas such as the "Multiple Potato Digging Machine" in Utility Model Publication No. 43-20771, in which multiple individual potato digging machines are installed in parallel on a conveyor with a plow-shaped excavator installed at the front. There are patent application No. 032584 of 1982 filed by the same applicant as the patent applicant.

The position is set immediately before the wheels on one side, and the harvested materials are transferred to the feed conveyor placed in parallel with the digging conveyor, so that the harvested materials can be efficiently loaded onto the hawk conveyor using a bucket mounted on the machine. The purpose is to

In addition, a digging port is also installed at the tip of a feed conveyor that is installed in parallel to the inside of the machine body to the digging conveyor, so that two rows of stocks can be dug and harvested at the same time. It is something.

[Means for Solving the Problem] As a means for achieving the above object, the present invention provides a method for towing a wheeled machine equipped with a digging device, a conveying device such as a hawk conveyor, and a storage device such as a bucket. , and in a tractor that supplies power, a machine body to which one wheel is rotatably attached so as to be able to step on the tracks of one wheel running at an outer position adjacent to the most end row of plants in the field is attached to the front tractor. The rear end of the rear feed-out portion is located immediately before the installation position of the wheels, and the installation position of the digging opening at the front end is set so that at least the center position in its width is located on one side of the tractor. A digging conveyor is provided on the machine body so as to be on the inner extension line of the wheels, and one side thereof is aligned with the track of the wheels on one side in a plan view, and a feed conveyor is provided adjacent to the other side of the digging conveyor. are arranged in parallel, and a rotating roller is installed obliquely above the rear of the digging conveyor, and the spheres being fed are guided by the rotating roller and transferred to the feeding conveyor. It is something.

Further, a digging opening is provided at the tip of the above-mentioned feeding conveyor so that two rows of stocks can be dug out at the same time.

[Operation] When the purpose is to harvest spheres, which are the harvested products of the outermost row of plants that form the outer periphery of a large field, one wheel of the tractor is moved along the adjacent outer side of the outermost row of plants. The wheels on one side of the body towed by this power vehicle are connected so as to maintain a state in which they match the ruts of the wheels on one side of the tractor, and the power is transferred from the tractor via a predetermined device. is supplied, and the cargo handling and conveyance means such as the digging conveyor and hawk conveyor on the machine side are operated, and the tractor is propelled to harvest the end row of stocks located inside one wheel of the tractor. The objects are located in front of the digging port at the front end of the digging conveyor, and as the machine advances, the objects to be harvested are placed on the digging conveyor.

The digging conveyor is arranged such that one side thereof is aligned with the track of one wheel of the tractor,
Moreover, the end of the conveyor belt is located just before the wheels on one side of the machine, and the harvested materials conveyed by rotating rollers installed diagonally on the upper surface are guided and transferred to the feed conveyor adjacent to the center side of the machine. and,
The materials to be harvested on the feed conveyor are transferred to a hawk conveyor by rotating rollers at the rear end, and are raised on the hawk conveyor and thrown into a bucket.
