Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for extracting and harvesting onions and the like. 2. Description of the Related Art Generally, a green onion production area has very hard soil, and some of the soil is hard to excavate due to abnormal hard soil.
Japanese Patent Publication No. 55-47843 is known as this type of burrowing machine for digging onions. A digging rotor is positioned between adjacent ridges of green onions, and is rotated and moved forward to one side of green onions. Sharp diagonally downward. While cutting the root at the lower end at the same time as the shaving, the cutting soil is brought to the other side ridge, and the operator pulls the green onion toward the groove side and pulls out. [0003] According to the above-mentioned conventional construction, after excavating one side of a cultivation ridge of green onions, the worker pulls out one by one, which is very heavy labor and is inefficient. There was a problem. [0004] In order to solve the above problems, a frame connected to a three-point link of a passenger tractor;
A digging blade on one side of the frame, a drive case, a digging portion of a green onion in which a pair of holding members for preventing left and right falling of the green onion are disposed, and the drive case has a gate column type and a transmission shaft is disposed inside. At the lower end, a main shaft is provided from left and right toward the center to drive the soil discharging means, and the pair of holding members are spread forward and forward, and are formed parallel at the center and the rear end is the front end of the holding belt It is characterized in that the upper layer of the deep onion is slid while excavating and excavating the left and right opposing parts of the cultivation ridge wall such as deep green onions, and then is continuously pulled out by the holding belt. A green onion harvesting device was provided. [0005] (2) [Action] While excavating and excavating the left and right opposing parts of the cultivation furrow wall of the deep onion, the soil around the deep onion stem and leaf is moved to the left and right, and at this time, the upper layer of the deep onion is held as a guide. Therefore, the upright posture is maintained and slid back and forth, and the upper part of the deep onion is nipped by a pair of nipping belts and continuously pulled out. An embodiment will be described with reference to the drawings embodying the present invention. FIG. 1 is a plan view showing the embodiment of the present invention, FIG. 2 is a cross-sectional view for explaining a left and right excavation operation of a main part such as a deep green onion, and FIG. 3 is a side view of the main part. [0007] Reference numeral 1 denotes a rear wheel of a tractor, which is not shown but is connected to a frame 2 of a harvesting device by a known three-point link for a riding tractor. The frame 2 comprises a pipe frame 12 and the like, and a pair of grounding wheels 16
Supported by Excavation blade 1 on one side of frame 2
A pair of holding members 8 for preventing the left, right, left and right sides of the drive case 5, the green onion and the like are arranged, and constitute a digging portion of the green onion and the like. Numeral 9 denotes a pair of conveying belts, which are formed of a soft rubber material having an uneven surface. The above-mentioned pair of holding members are formed such that the front part is widened at the front and the center part is formed in parallel, and the rear end is overlapped with the front part of the holding belt 9. Reference numeral 11 denotes a work belt which is a flat belt orthogonal to the rear end of the holding belt 9 and rotated as necessary.
Or let it stand still. 3 is an input case of the tractor PT described above.
Input from O through a transmission means, one of which is transmitted through the inside of the pipe frame 12 and transmitted to the drive case 5. The other of the input case 3 is transmitted to the sub case via a suitable transmission means, and transmits the work belt 11 and the holding belt 9. In FIG. 2, a drive case 5 is formed in a column shape, and a transmission shaft 15 is disposed inside the drive case 5. A main shaft 14 is provided at the lower end from left and right to the center to drive the earth discharging means 13. In this embodiment (3), a large number of claws are attached in the radial direction, and excavated soil is released to the left and right of the green onion. The left and right dump plates may be vibrated. Reference numeral 10 denotes an excavating blade, which is provided obliquely downward from the outside of the drive case 5 to cut the root of the green onion. Reference numeral 8 denotes a holding material which is arranged in a pair on the left and right in a parallel manner, and when the shoulders of the leek ridge begin to collapse, the holding belt 9 prevents the leek from falling down.
Is to be guided to the beginning. The supporting portion of the holding member 8 may be provided with an appropriate elastic material or a predetermined gap may be provided in advance. FIG. 3 illustrates the digging action of the green onion in the planted state.
The above-mentioned discharging means 13 rotates from the left and right to break the shoulder of the ridge, and the excavating blade 10 cuts the root hair at the lower end of the green onion.
Since the left and right discharging means 13 is discharging the shoulder of the furrow, the upper layer of the green onion slides while being prevented from falling down by the pair of holding members 8. The green onion is forcibly guided at the rear end of the holding member 8 to the start end of the holding belt 9. Then, the holding belt 9 pulls out the green onion while gripping the upper part of the green onion and moving to the upper layer. As described above, crops such as deep green onions are forcibly ejected from both shoulders of the cultivation furrow and are successively guided to the holding belt to be pulled out for harvesting work. It became smooth and efficient.
