Abstract

PURPOSE:To provide a carrot harvester so designed that carrot stems and leaves are cut in two steps, thereby ensuring clear cut, promising such advantages as to be unnecessary for their recutting. CONSTITUTION:Carrot stems and leaves N1 dug up are held with a carrot conveyor and conveyed backward; during this process, the stems and leaves N1 are put to primary cut with the first cutter, and the carrots N thus cut are transferred to a sorting conveyor, and the lower parts N11 of the stems and leaves N1 of these carrots N being in movement backward on the screening conveyor are cut with the second cutter.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrot harvester.

[0002]

2. Description of the Related Art Heretofore, in this type, the following has been done. 1. Carrots are only removed. 2. Hanging carrots and only roughly cutting the leaves of carrots with a cutter.

[0003]

The problems described in the prior art have the following problems. 1. The foliage is not cut completely. 2. Re-cutting of the foliage is required, the efficiency is equivalent to manual work, and labor is not saved. 3. Sorting work is difficult. 4. Post-processing is difficult because it is carried into the sorting site by rough sorting. (There is disposal of nonstandard products.) 5. It is a wheel type self-propelled device that does not work well during rainfall.

The present application has been made in view of the above problems of the prior art, and an object of the present application is to provide a device capable of solving the above problems.

[0005]

In order to achieve the above object, the present invention is as follows. That is, according to the present application, the ginseng foliage N1 dug up with soil by the digging blade is sandwiched by the ginseng conveyor and is conveyed backward while being conveyed by the first foliage cutter.
1 is first cut at a position slightly higher than the position where the carrot transport conveyor is clamped by the V-belt, and the first cut ginseng foliage N1 is sandwiched by the foliage discharge conveyor and conveyed and discharged laterally. The carrots N that have been primarily cut are directly conveyed backward by the carrot conveyor, and then the carrots N separated from the carrot conveyor are moved to the leading end of the sorting conveyor while being inverted by the carrot alignment guide, and are then sorted. The carrot N that has reached the conveyor is moved rearward with the shoulders N12 of the carrot N aligned outward, and the lower portion N11 of the foliage N1 of the carrot N that has advanced in this manner is the second foliage. It is a carrot harvester that is configured to cut with a cutter. In this case, a pair of left and right ginseng transport conveyors, first foliage cutters, foliage discharge conveyors, ginseng alignment guides, sorting conveyors, second foliage cutters, etc. can be configured.

Are connected through. With such a crank mechanism, the tip of the divider moves up and down. As a result, the entanglement of the foliage of carrots between adjacent ridges can be disentangled, and the entanglement of the foliage can be improved. G is a gear box.

The present invention operates as follows. 1. Place in the field and proceed with this device. 2. Even if the ginseng foliage N1 planted in the adjacent ridge is entangled, it is separated by the oscillating divider 20. 3. The carrot N is dug up with the soil by the digging blade 17. 4. The ginseng foliage N1 is placed on the left and right carrot conveyors 3, 4
It is pinched by the left and right V-belts and is conveyed backward. 5. When the positions of the left and right first foliage cutters 5, 6 are reached,
The carrot foliage N1 is primarily cut at a position slightly above the position where it is clamped by the V-belt.

6. The carrot N that has been firstly cut is conveyed backward as it is by the carrot conveyors 3 and 4. 7. The primary cut carrot foliage N1 is sandwiched between the foliage discharge conveyors 7 and 8 and conveyed laterally.
At this time, the foliage discharge auxiliary belts 7D and 8D attached to the foliage discharge conveyors 7 and 8 are used to convey the foliage N1 of the ginseng being conveyed.
Constantly pushes to the side. 8. Carrots N reaching the rear end with carrot conveyors 3 and 4
Will be separated from the carrot conveyors 3 and 4, but the carrot N is sandwiched by the carrot conveyors 3 and 4, and due to the special structure of the rear end portion as described in the embodiment,
The lower part N11 of the foliage N1 of carrot remains.

9. The carrot N separated from the carrot conveyors 3 and 4 moves to the front end portions of the left and right sorting conveyors 9 and 11, respectively, while being turned over by the carrot alignment guides 10 and 12. 10. The carrot N that has reached the sorting conveyors 9 and 11 moves rearward while aligning the shoulder portion N12 of the carrot N toward the outside. 11. At this time, the shoulder portion N12 of the carrot N is manually brought into contact with the flange 11B2 of the taper roller 11B as shown in FIG. In this case, the defective carrot N is excluded and the defective carrot is discharged from the discharge tube.

12. Ginseng N that progressed in this state
The lower part N11 of the foliage N1 is the second foliage cutter 1 on the left.
3 and the second forage cutter 14 on the right side, respectively. At this time, the carrots are ginseng holding tubes 15, 16
Can be pressed lightly with. 13. The carrot thus treated is stored in a carrot storage bag 22 suspended at the rear ends of the sorting conveyors 9 and 11. The carrot storage bag 22 is supported by a crane 23 standing upright behind the self-propelled device 2.

[0025]

Since the present invention is constructed as described above, it has the following effects. Since the foliage cutting work is performed in 1.2 steps, the cut can be cut surely. 2. No need to rework. 3. 80% of sorting work can be performed. 4. Since there are few nonstandard products, it is possible to improve the efficiency of boxing work in the sorting field.
