Description

An Underground crop harvester equipped with gathering device

The present invention is for the crops excavated from the excavation part to be moved backwards along the transport part and separated from the soil to fall to the ground, so as to collect the fall position to the center of the dug as needed or to drive it to either side. By providing a collection device, it is possible to prevent the crops excavated by the tractor wheels from being trampled or crushed again during the continuous excavation of adjacent banks, and to efficiently collect the crops.

In general, a crop harvester (a bulb harvester) is an agricultural machine used to harvest various root crops such as sweet potatoes, potatoes, garlic, ginseng, deodeok, bellflower, etc., which are grown in the ground. It is classified as a harvester, a tractor or a cultivator, and is a towed harvester harvested while driving.

Prior art for the towing-type crop harvester related to the present invention may include Patent Documents 1 to 4, in Patent Document 1, the bulbs protruding from the ground are transported to the rear on a transport conveyor, but the transport conveyor is intermittently driven to drive the bulbs It is configured to remove the soil attached to the inertia, and there is provided a sorting conveyor and a seat provided at the rear, and a bulb harvester configured to allow a work assistant to sit on the seat and sort crops from the sorting conveyor.

Patent Document 2 also discloses a harvester of bulbous crops configured to load a collection container at the rear of the harvester and classify the excavated crops by size when they pass through the sorting unit to be loaded into the collection container.

Patent Document 3 discloses a folding bulb harvester that is provided with a sorting conveyor and a passenger seat at the rear of the harvester to sort and collect the harvested crops.

Patent document 4 also discloses a harvester-boarding harvester.

On the other hand, the above-described prior art traction-type crop harvester (bulb harvester) had a problem that the size of the equipment was too large and the operation was possible in a large field because the sorting conveyor and the sorting worker had to board the rear of the harvester. There was a problem in that it was impossible to harvest by inputting such equipment when the width and shape of the weirs where crops were grown for each region were different.

In addition, as described above, the practice of cultivating crops varies from region to region, and the width and width of the weir are different depending on the type of crop, so a general underground crop harvester without a separate sorting conveyor is used as a tractor. When towing and excavating, the crop falls over a wide area on the bank, so when excavating the next bank, the tractor's wheels trample crops that are already on the excavated site, degrading the marketability, or excavating the crop again. There is a problem that is getting caught in the inside.

The falling direction of falling crops can be changed.

Reference numeral 429 in the figure serves to prevent the crops falling from the end of the secondary inclined guide portion 428 to an extension extending downwards to fall outside the designated lowering position and at the same time to mitigate the impact when falling to the ground. Is done.

Underground crop harvester of the present embodiment configured as described above is separated from the soil while being transported rearward along the transport unit 300 when excavated in a state where both the left and right guide plates 420 are lowered down (see FIGS. 8 and 9 ). When the harvested crops are gathered to the center of the weir, and one of the left and right guide plates 420 and 420' is lifted as shown in FIG. 10 (in the drawing, both guide plates are shown in a lifted state). The crop is intensively dropped in the direction, and the crop transferred to the rear by the guide plate 420 or 420' lowered to the rear lower part falls to the ground, and then collides with the second inclined guide unit 428 to the ground. As it will fall, the guide plates 420 and 420' will fall as the crop is driven to the lifted position.

On the other hand, in this embodiment, since the left and right guide plates 420 and 420' can be maintained in a lifted state, when it is necessary to drop the crop over the entire area of the weir, harvesting may be performed in this state. When moving, it is possible to make both the left and right guide plates 420 and 420' lifted so that the length (length) of the harvester can be reduced.

As described above, according to the present invention, when the crop excavated from the excavation part in front of the frame is transferred to the rear upper part along the transport part and is separated from the soil and then falls to the ground, the crop of the left and right sides is adjusted by adjusting the direction of the guide plate. Since the location can be gathered to the center of the ridge or driven to either side of the left and right sides, it is possible to prevent the crop crushed by the tractor wheel from being trampled or damaged during the continuous crushing operation of the adjacent ridge. The collection efficiency can also be improved, and crops falling by the bone-forming blades, which can be height-adjusted in the lower part of the conveying part, can be prevented from flowing down into the furrow, and the surface of the crop is made by the soft hose inserted into the chain rod of the conveying part. As well as being protected, it can be prevented from rolling forward while transporting to the rear upper part, and a tractor blade is used to cut the soil on both sides of the bone and cut the stem or root of the crop by the disc blade installed to be separated from the frame in front of the frame. It also has the advantage of efficiently harvesting the crops under the ground by reducing the traction load of the plant.
