Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for harvesting underground crops.

For example, when harvesting underground stem crops such as potatoes using a digging machine, conventionally, before digging up the underground stem crops,
Alternatively, at the same time, the stems and leaves growing on the ground were harvested, and underground crops were dug up without cutting the stems and leaves, and then the stems and leaves were removed. In the case of this method, the cut stems and leaves or at least the remaining stems will be mixed into the underground stem crops that are dug up, so the underground stem crops will be damaged such as peeling due to friction with the remaining stems, etc. It was extremely inconvenient.

In addition, when digging underground crops, cutting the stems and leaves in advance and then digging up the underground stem crops is extremely inefficient if the cutting of the stems and leaves and the digging of the underground stem crops are not done at the same time. It had the disadvantage of being bad.

The present invention has been made in view of the above circumstances, and is designed to remove the stems and leaves of underground stem crops without leaving any remaining stem parts, and to prevent damage to the underground stem crops during digging. To efficiently pull out the stems and leaves by simultaneously digging out underground stem crops in a process adjacent to the process of pulling out the stems and leaves. The purpose of this paper is to provide a harvesting method and device that can achieve this goal.

An embodiment of the present invention will be described with reference to the drawings.

It is formed by mounting an endless band 22, such as a sieve rod 21, through a sprocket 19 and an endless chino 20 between rotating shafts 17 and 18 on both sides.

The above-mentioned structure forms the stem and leaf pulling device A.

Note that the above-mentioned upper restraining body may be formed by a roller instead of the sliding plate 13.

Next, B is an excavation device, and the excavation device B includes one side frame plate 1b of the above-mentioned both side frame plates 1at1b, and a frame plate 1C disposed opposite to the outside of this one side frame plate 1b. Both side frame plates 1b and 1c are constructed as a machine frame, and a digging blade 23 as a digging body is provided at the front lower part between the both side frame plates 1b and Ic. It is formed by arranging a sieve conveyor body 24 in series, and by arranging a second cross conveyor body 25 in series at the rear of this soil sieve conveyor body 24.

The upper sieve conveyor 24 has the above-mentioned both side frame plates 1btlc.
Rotating shafts 26 and 27 are horizontally mounted on the front and rear sides of the machine, and an endless chain 29 is hung and rotated via a sprocket 28 on both sides between the front and rear rotating shafts 26 and 27. It is formed by passing the horizontal rods 30 at regular intervals, and the second horizontal feed conveyor body 25 is connected to the rear parts of the both side frame plates 1 b and 1 c via support frames 6 to provide rotation on both sides. The shafts 31 and 32 are mounted on a shaft, and a sprocket 33 and an endless chino 34 are mounted between the rotating shafts 31 and 32 on both sides.
It is formed by rotating an endless band 36 made of a sieve rod 35 through the sieve rod 35.

The main frame 37 is located between the front upper parts of the above-mentioned both side frame plates 1 b and 1 c.
The main transmission 38 is attached to the center of the main frame 3γ and the upper front of the main transmission 38
A connecting frame 3 for a tractor (not shown) is located in front of both measuring sections.
9 is protruded from the front part of the main transmission 38, and an input shaft 38b is protruded from the front part of the main transmission 38. a rear rotational vertical shaft 9 as a drive shaft; a rear rotation shaft 27 as a drive shaft in the upper sieve conveyor body 24; and the first and second traverse conveyor bodies 16.

The upper stems and leaves 43 are guided between the weeding frames 4 and introduced between the guide bodies 2 and pulled up, and the ground on both sides is dug by the sliding plates 13, and then conveyed to a pair of endless conveyor bodies. 3, and as the endless conveyor body 3 rotates, it is pulled out while being transferred rearward and upward, and is transferred and placed on the first lateral conveyor body 16. It is released to the ground from the transfer end.

At the same time as the foliage part pulling out device A pulls out the foliage part 43, the ridge 41b is removed in the process adjacent to the foliage part pulling process.
, the digging blade 23 in the digging device B digs up the potatoes 42 in the ridge 4Ib from which the stems and leaves 43 have been removed in the previous step, transfers them onto the soil sieve conveyor body 24, and transfers them onto the soil sieve conveyor body 24. The body 24 sifts off the soil and transfers the potatoes 42 as a harvest onto the second lateral conveyor body 25, and the potatoes 42 are discharged to the ground from the transfer end of the second lateral conveyor body 25. Ru.

According to the present invention, when harvesting underground crops by digging, the pair of guide bodies on both sides pull up the stem and leaves, and the pair of soil holding bodies on both sides suppress the soil located on both sides of the stem and leaf. Since the endless conveyor body pulls out the stems and leaves, the fallen stems and leaves are raised up, and the stems and leaves are pulled out while the soil is held down by the soil suppressing body, so only underground stem crops can be placed underground. In this state, the foliage, including the part located underground, will be pulled out from the root, allowing for good separation from the underground rhizome crops that will be dug up afterwards, and the foliage will be left underground. In addition, since the underground stem crops are excavated in an adjacent process at the same time as the stems and leaves are pulled out, the underground stem crops are not contaminated with underground stem crops. Digging and harvesting will be carried out successfully and efficiently.
