Description

[Detailed description of the invention] This invention mainly relates to a foliage cutting device for an excavator for digging up agricultural products such as potato and corn.

The excavator is towed by a tractor or tiller,
The digging blade A at the tip is embedded in the soil, and the agricultural products and soil are placed on the elevator B together, and while moving backward, the soil falls through the gap in the lot of the elevator B, leaving only the harvested products on the rear side. Or drop it on the ground
Alternatively, they are stored in a separate container, but as the plants such as potato plants are dug up with their stems and leaves still attached, the stems and leaves often get tangled with the excavator and cannot be sent backwards properly.

When the stems and leaves get entangled, the following ones get caught up in them, and the potatoes etc. immediately clog the elevator B, and the outer surface of the harvested potatoes, etc. gets rubbed by the operation of the elevator and the outer skin comes off. Scratches occur, leading to a decline in quality, and it is necessary to stop the excavator and remove the tangles by hand, which significantly reduces work efficiency.

In order to prevent such tangles of leaves and stems, there were cases where the leaves were harvested in advance, but this was uneconomical as it required 4 to 5 hours per 10 are in the case of barley.

This invention is intended to solve this problem of the conventional machine, and will be explained below based on the attached illustrative drawings.

In the excavator shown in Fig. 1, 1 and 1 are rotary blades, which are disc-shaped with cutting blades on the outer periphery and are used to cut stems and leaves using the power of the excavator. At the positions of the recessed portions 5, 5 on the upper sides of the side plates 2, 2 which stand upright, a part of the cutting edge on the outer periphery is provided so as to protrude from the upper sides.

The cutting blade 1 has some protrusions on its outer periphery, such as a circular saw blade, or a knife-like blade with a sharp outer periphery. Furthermore, if a receiving blade 4 is provided that surrounds a part of the outer periphery of the cutting blade 1, the cutting effect of the stems and leaves will be further improved.

The rotation of the cutting blade 1 is transmitted from the drive shaft of the elevator B by a belt, as an example.

According to this configuration, the stems and leaves of potatoes that have been dug up by the horigori blade A are removed from the side plate 2,
When riding the elevator B while riding on the upper side of 2, the stems and leaves are cut by the cutting blades 1, 1 and reach the structural part behind the cutting blades 1, 1 where the stems and leaves tend to become entangled. When removed, functional disorders caused by entanglement of stems and leaves can be prevented, and the excavation work can proceed normally.

As described above, the present invention is advantageous because it prevents the stems and leaves from becoming entangled by simply providing a simple cutting blade, does not damage the outer surface of the harvested product, and does not reduce quality. There is no need to interrupt work to untangle the leaves,
The overall economic effect is truly great, such as greatly improving work efficiency and eliminating the need to harvest stems and leaves in advance.
This has the effect of making it possible to expand the scale of farming.
