The present invention relates to a bulb crop harvester, and more particularly, to a bulb crop harvester capable of automatically harvesting a bulb crop such as sweet potato and onion with high productivity.

In general, ground bulbs (ie, ground crops) include potatoes, sweet potatoes, onions, garlic, and carrots, and when harvesting these bulbs by manpower, they must be dug up and harvested. In recent years, a harvester, which is a farming machine that can be harvested mechanically and quickly and easily, has been developed. Most of these harvesters are detachably connected to the rear of an agricultural towing vehicle such as a tractor. It is a type that receives various driving force.

However, these harvesters are harvested continuously by excavating only the bulbs grown in the ground, and for the excavation work, the worker must first remove the stems on the ground by hand, which delays the work time and removes many stems. Manpower is required.

In addition, since the bulb crop is usually grown in a state covered with vinyl on the arable land, such vinyl should also be removed manually by the worker prior to the excavation work, which also causes a delay in working time and cost.

The present invention was devised to solve the above problems, and is configured to be integrated with the trackless traveling gas, and has its own power, and can perform the stem removal work and the vinyl recovery work at the same time in parallel with the excavation work. The purpose is to provide a bulb crop harvester that can improve the productivity of harvesting.

Here, the bulb conveying conveyor 500 is not shown, but the configuration is almost similar to the above-described jet conveyor 350, a pair of inner side plate portion 510 which are arranged in parallel with each other along the direction of travel, and predetermined Transfer conveyor 520 and the conveying conveyor is arranged to be rotated in the front and rear direction between the two inner side plate portion 510 to form a closed endless track for rotation with a plurality of rods arranged at a pitch, and the conveying conveyor The third rotational drive unit 530 rotating the unit 520 and the transfer conveyor unit 520 inside both inner side plate parts 510 are provided in the upper part of the micro interval, and gradually transfer the harvested portion to a predetermined region on the center or both sides. The inner convergence plate portion 540 is collected.

In addition, the bulb transfer conveyor 500 may be provided to protrude rearward from the rear end of the caterpillar running gas unit 200.

Further, since the bulb crop is typically grown in a state covered with vinyl on the arable land, such vinyl must also be removed and recovered at harvest, for this purpose, a vinyl recovery unit 600 is provided.

The vinyl recovery part 600 is provided on the rear end side upper portion of the crawler traveling body part 200, and its configuration is a vertical support rod part 610 which is placed on both sides in the upper direction from the rear end side of the crawler traveling body part 200. ), A winding bar unit 620 provided to be rotatable between the two vertical support rods 610, and a winding drive unit 630 for winding to rotate the winding bar unit 620.

Therefore, the vinyl is transported and discharged through the lower bulb conveying conveyor 500 to the winding bar 620 rotated from the upper side by the winding driving unit 630 to be recovered.

The operation of the bulb crop harvester 100 according to the present invention having the above configuration will be briefly described below.

When the operator seats on the driver's seat 230 and starts the operation through the operation panel 240, the power generator 220 is driven. Then, when the operator travels by the operation of the operation panel 240, the carter pillar unit 210 is driven. Rotate and drive.

On the other hand, in the arable land in which the grown bulbous crop is planted, the operation of the control panel 240 reversely operates the first height adjustment cylinder part 370 to lower the front bulb harvesting part 300 downward, and further, the second. By operating the height adjustment cylinder 470, the stem harvester 400 is also positioned at an appropriate height.

Subsequently, the first height adjustment cylinder 370 is operated while driving forward, so that the horizontal blade 330 of the bulb harvesting unit 300 is inserted into the ground.

Next, the bulb harvesting unit 300 and the stem harvesting unit 400 are operated by driving the first rotational drive unit 360 and the second rotational drive unit 460 to move forward.

Accordingly, the stem is removed through the stem harvesting unit 400 while traveling, which is cut by the cutting cutter 430 and the stem cut through the stem compulsory inlet 450 is harvested frame part. 420 After being drawn into the inside and then transferred to both sides by the screw plate 444 of the cutting screw 440 in the harvesting frame portion 420 collected by the push plate 446 of the cutting screw 440. The collected stems are discharged through discharge holes 422 formed at both ends of the harvesting frame part 420.

At the same time, the harvest is made through the bulb harvesting unit 300 with respect to the bulb of the ground from which the stem is removed, which horizontally cuts the soil including the harvest horizontally in the ground at a predetermined depth. Soil and vinyl containing the cut crops are then passed through the soil shaker 340 and the zeolite conveyor unit 350, the soil is soiled and only the harvest and vinyl are continuously transported to the rear.

Subsequently, the harvest and the vinyl passing through the zeto conveyor unit 350 are continuously transported rearward through the bulb transport conveyor unit 500 inside the crawler traveling gas unit 200.

The vinyl conveyed to the rear end of the caterpillar traveling gas unit 200 is initially wound on the winding bar 620 of the vinyl recovery unit 600 by an operator and automatically wound up continuously, and the bulb transport conveyor 500 The harvest transported to the rear end of the tree will fall to the ground.

In this way, the harvested bulbs dropped to the ground may be collected by the worker, and alternatively, may be configured to be dropped and stored in storage containers such as bags without falling directly to the ground.

Thus, it is possible to quickly harvest the bulb crops by the continuous repeating operation as described above.

In the foregoing description, it should be understood that those skilled in the art can make modifications and changes to the present invention without changing the gist of the present invention as merely illustrative of a preferred embodiment of the present invention.

According to the present invention, it is possible to smoothly perform the entire work of stem removal and vinyl recovery at the same time as harvesting the bulb can be achieved to improve the productivity of the harvesting operation.
