These bulbs can be harvested by digging the ground with agricultural tools such as hoe. If the cultivation area of the crop is small, it can be easily harvested with little labor, but in large-scale cultivation, a large amount of labor is required, so a harvesting device using mechanical power is used to lower the production cost.

Such an underground plant harvesting apparatus includes an blade part inserted into the ground at a predetermined depth for the mining of bulbs, and a transfer conveyor for transferring soil and bulbs mined by the blade part in the rear area of the blade part to the rear ground. Here, the conveying conveyor is formed in a caterpillar type having a plurality of rods arranged in parallel so as to separate and transport the bulbs provided by the blade part from the soil, and the area adjacent to the blade part along the moving direction is lower. It is arranged to be inclined upward toward the rear so that it can be placed on.

At this time, the underground plant harvesting device is coupled to the rear area of a towing vehicle such as a tractor, and as the towing vehicle advances, the blade is moved in a state in which the blade is inserted at a predetermined depth into the ground, so that the soil and bulbs are moved to the rear area by the blade. It moves upward. Then, the transferred soil and bulbs are placed on a transfer conveyor rotating in a clockwise direction, and foreign substances such as soil or small stones having relatively small particles fall to the ground through the space between the rods and are separated. Here, the bulbs are transferred to the rear area and fall to both sides of the device and are aligned along the traveling direction.

However, in the case of the prior art as described above, if there are many foreign substances such as soil or stones, all foreign substances cannot fall to the ground through the space between the rods and are put into a sack that receives the bulbs. There is a problem in that foreign substances such as the back must be additionally removed.

After that, when the underground plants are sufficiently accommodated in the collection member 241, the upper plate 263 is rotated upwardly to separate from the lower plate 262 as shown in FIG. 7D.

The separated lower plate 262 is directed downward by its own weight so that the collection member 241 can be separated.

Meanwhile, the underground plants delivered from the discharge guide 25 are dropped and accommodated by the collection member 241 seated in the collection device 24, at this time, the height difference of the collection device 24 from the discharge guide 25 The larger the drop, the larger the drop, and the underground plants can be damaged by impact.

In order to prevent this, the sorting part 2 is mounted so as to be elevated at the rear end of the sorting body 21 and the collecting device 24 is fixedly installed on one side of the sorting body. It further includes a cylinder 27 for interlocking with the flow frame 271 lifting and lowering.

The collection device 24 by the flow frame 271 and the cylinder 27 adjusts the height difference from the discharge guide 25, so that the underground plants fall and are accommodated in the collection member 241 by impact. It becomes possible to prevent damage.

Here, since various known technologies exist for the cylinder 27, a detailed description thereof will be omitted.

It will be appreciated by those skilled in the art through the above description that various changes and modifications can be made without departing from the technical idea of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be determined by the claims.
