Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention relates to sweet potatoes, potatoes, onions,
The present invention relates to a harvester for extracting root vegetables such as beets and small-scale agricultural crops from a field for selection.

[0002]

2. Description of the Related Art A conventional harvester is disclosed in Japanese Unexamined Patent Publication No. 30620/1994.
As is known in Japanese Patent Publication, an inclined conveyor for digging agricultural products from the ridges and lifting them up is arranged linearly from the tip of the ski to the rear of the machine, and the harvest container is placed behind it and the operator It was arranged on both the left and right sides of the inclined conveyor. This conventional harvester has a drawback in that the operator has to secure a space on the side of the inclined conveyor, so that the entire length of the machine becomes long and it becomes difficult to change the direction of the harvester and steer the turn.

[0003]

SUMMARY OF THE INVENTION The problems to be solved by the present invention are to solve the drawbacks of the conventional harvester, shorten the length of the machine body, make the sorting work easier, and make the operation and work seats easier. The purpose is to provide a harvester that can be shared and is easy to operate and control.

[0004]

[Means for Solving the Problems] The structure of the present invention which has solved the above problems is as follows: 1) A transverse feed conveyor is provided at the end of an inclined excavation conveyor that excavates agricultural products from ridges and lifts them upward. A harvesting machine characterized by having a working seat that doubles as a sorting seat and a driver seat behind the feed conveyor 2) The harvester described in 1) above, in which a crusher for agricultural products is provided at the end of the horizontal feed conveyor 3) The harvesting machine according to the above 1) or 2), in which the lateral feed conveyor is switched in both left and right directions, and another working seat is provided on the side of the lateral feed conveyor on the opposite side of the working seat that also serves as the driver's seat.

[0005]

In the present invention, the agricultural products in the field are dug up from the field by the tip of the excavation conveyor, lifted by the inclined excavation conveyor, transferred from the end thereof to the transverse feed conveyor, and sent to the left or right. . The operator operates the harvester at the rear of the horizontal conveyor, selects the agricultural products sent by the horizontal conveyor, and transfers only the agricultural products of the required quality and dimensions to the collection box. As described above, the sorting operator selects the agricultural products to be sent by the lateral feed conveyor while looking forward from the driver's seat, which facilitates the sorting while driving, and enables a single person to perform the selective digging work. In addition, since the side-by-side conveyer can expand the place for selection to the left and right, the work seats can be arranged on the left and right, so that the length of the dug conveyor can be shortened and the machine length can be shortened. If the horizontal conveyor can be switched to both left and right directions, agricultural products can be transferred in either direction, and another worker can be lined up on the horizontal conveyor so that the operations and sorting work can be shared. If a crusher is installed at the end of the horizontal conveyor, it crushes agricultural products that are not sorted by the horizontal conveyor so that they do not germinate and may be returned to the field. The volume of the bag container can be reduced.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of the embodiment, and FIG. 2 is a side view of the embodiment. In the figure, 1 is a digging conveyor in which rods are suspended at a fixed pitch between the left and right endless belts, 2 is a lateral feed conveyor, 3 is a working seat that also serves as a driver's seat, and 4 is a collection box for collecting selected agricultural products. Reference numeral 5 is a control unit, 6 is an engine, 7 is a reduced transmission mission, 8 and 9 are different working seats, 10 is a discharge chute provided at the end of the lateral feed conveyor, and 11 is a dug conveyor 1.
The tip of the skim, 12 is a crawler body, 13 is a sweet potato which is an agricultural product, 14 is a V-belt, 15 is a conveyor sprocket of the excavation conveyor 1, 16 is a chain, and 17 is driven via a forward / reverse switchable mission 21. Conveyor roller of the horizontal feed conveyor 1, 18 is a traveling mission, 19 is a crushing and crushing device, and 20 is a crushing roller of the same crushing and crushing device.

In this embodiment, the operator at the work seat 3 is operated by the control unit 5
The operating lever is operated to operate the crawler body 12, and the working machine is caused to travel along the ridge of the field. Sweet potato 1 in the ridge of the field
3 is dug up by the skid point 11 of the digging conveyor 1, and is mounted on the digging conveyor 1 and rises. In the digging conveyor 1, since the bar material is suspended between the endless belts at a constant pitch, sand, stones, etc. attached to the digged sweet potato 13
Small sweet potatoes 13, small pieces of soil fall from the voids between the bars. Sweet potatoes 13 above a certain level are digging conveyor 1
Then, the sheet is transferred to the lateral feed conveyor 2 from its end and is sent to the left or right. When it is sent to the left side, the operator who sits in the working seat 3 that also serves as the driver's seat sorts out the sweet potatoes 13 on the lateral feed conveyor 1, and if the size and quality are above a predetermined level, the laterally feed conveyor 1 is manually operated. It is moved to the collection box 4. The defective sweet potatoes 13 that have not been sorted fall from the end of the lateral feed conveyor 1 to the discharge chute 10 and further between the pair of crushing rollers 20 of the crushing and crushing device 19, and the crushing rollers 20 crush the defective sweet potatoes. However, it is broken and crushed and dropped on the soil in the field below.

If workers are placed in the right working seats 8 and 9,
The lateral feed conveyor 2 is fed to the right, the sweet potatoes 13 are sorted by the operator on the right side, and the qualified products are collected in the collection box 4. The defective sweet potato 13 is crushed and crushed by the crushing roller 20 of the crushing and crushing device 19 on the right side and returned to the field. in this way,
Since the horizontal feed conveyor 2 is provided and sorting is performed on the horizontal feed conveyor 2, a sorting operator can be a driver, and an operator only for sorting can be arranged along the horizontal feed conveyor 2 and the length of the digging conveyor 1 can be increased. It can be shortened. In addition, the sorting work becomes easier.

[0009]

As described above, according to the present invention, the traverse conveyor is provided at the end of the excavation conveyor and the crops can be sorted by the traverse conveyor, so that the driver can perform the sorting work. , Even one person can work efficiently. Since another sorter can be placed along the horizontal feed conveyor, the excavation conveyor can be shortened, the total length of the harvesting device can be shortened, and the operation and transportation are easy. Further, in the case where the crusher is provided at the end of the lateral feed conveyor, since the defective agricultural product is crushed and returned to the field, it is possible to prevent the defective agricultural product returned to the field from germinating and hindering the farming.
