DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ginseng harvester for harvesting ginseng and storing the harvested ginseng in a storage box. The present invention relates to a ginseng harvester that is not likely to break.

[0002]

2. Description of the Related Art Harvested carrots are cut off from the ginseng body before being shipped to the market, and are then washed. The cutting of the leaves of carrot is usually performed manually using a sickle, a kitchen knife or the like. However, such a manual operation has a problem in that the operation efficiency is poor and it takes a long time to process a large amount of ginseng.

[0003] In order to solve such a problem, Japanese Utility Model Publication No. 64-2636 discloses that ginseng with leaves sequentially conveyed on a conveyor belt is placed on the side of the conveyor belt while the leaves are being pulled by a pulling roll. A device has been proposed which leads to an arranged cutter and cuts by the cutter. In this device, the ginseng main body, whose leaves have been cut, flows down along the falling plate and is put into a storage box disposed below the falling plate.

[0004]

In such a device,
When the ginseng body whose leaves have been cut flows down along the falling plate and enters the storage box, the drop between the falling plate and the storage box is large, so it is severely impacted and cracks or breaks Or In particular, when the ginseng main body is initially put into the housing, a large impact is applied to the ginseng main body falling to the bottom of the housing box, so that the ginseng main body is likely to be cracked or broken. In addition, in the state where the ginseng main body is stored in the storage box, if the ginseng main body put into the storage box further violently collides with the ginseng main body stored in the storage box, it is already stored in the storage box. The carrot body may be cracked or broken.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a ginseng that can be reliably stored in a storage box without breaking or breaking the ginseng when harvesting the ginseng. To provide a harvester.

[0006]

The ginseng harvester of the present invention comprises:
A belt conveyor that conveys the harvested ginseng with leaves, and a belt conveyor that conveys the leaves of the ginseng with leaves conveyed on the belt conveyor to the side of the machine body with the leaves of the ginseng pulled in downstream in the conveyance direction of the belt conveyor. The guide direction is arranged in an inclined state and the guide roller is rotated in a predetermined direction, a cutter that cuts a leaf portion of a ginseng with leaves guided by the guide roller, and a ginseng body portion whose leaves are cut are provided. A flow-down plate arranged in a predetermined inclined state toward the outside and downward on the side of the belt conveyor so as to flow down to the side of the belt conveyor, and the storage box is placed below the flow-down plate. And a supporting table supported by the body so that the loaded storage box can rotate from an inclined state along the downflow plate to a substantially vertical state, and mounted on the supporting table. The placed storage box A buffer for urging the support base with a predetermined urging force so as to sequentially transition from the inclined state along the falling plate to the vertical state in accordance with the weight of the ginseng main body put into the storage box. , Is provided.

[0007]

In the ginseng harvester of the present invention, the ginseng with leaves conveyed on the belt conveyor is guided to the side of the machine body in a state where the leaves are drawn in the conveying direction downstream of the belt conveyor by the guide rollers, The leaves are cut by a cutter. Then, the ginseng main body portion whose leaves have been cut flows down in a horizontal state along a downflow plate provided on the side of the belt conveyor, and is housed in a housing box placed on a support table. In this case, the ginseng main body part whose leaves have been cut flows down along the inclined falling plate, and is accommodated in a storage box inclined similarly to the falling plate.
As a result, the relatively flexible ginseng body is successively accommodated in the accommodation box in a horizontal position without breaking or breaking, in order to flow down along the side of the falling plate and the accommodation box. . When the ginseng is accommodated in the accommodation box, the shock absorber shifts the support base from the inclined state to the vertical state sequentially according to the weight of the accommodated ginseng body. The ginseng body part is housed horizontally in the inside of the storage box that shifts to the vertical state, and the ginseng body part newly flowing down along the falling plate is buffered by the ginseng body part housed inside the storage box. Since it functions as a material, it is securely housed inside the housing box without cracking or breaking.

The belt conveyer 20 has an upper surface that is substantially at the same level as the lower surface of the ginseng table 13. The belt conveyor 20 is circulated by the prime mover 11 on the traveling vehicle 10 so that its transport surface moves toward the front of the traveling vehicle 10. On the upper surface of the belt conveyor 20, the ginseng with leaves placed on the ginseng placing table 13 is sequentially transferred and transported.

A guide roller 30 is disposed above the belt conveyor 20 from the middle to the end. The guide roller 30 is inclined with respect to the moving direction of the upper surface of the belt conveyor 20, and its peripheral surface is separated from the conveying surface of the belt conveyor 20 by a predetermined distance at which the ginseng leaves can enter. It is open. The guide roller 30 is rotationally driven so that the lower peripheral surface facing the upper surface of the belt conveyor 20 on which the carrot is placed moves in the same direction as the upper surface of the belt conveyor 20. The ginseng conveyed on the belt conveyor 20 changes its posture with the ginseng main body abutting on the guide roller 30, and the leaves are pulled in between the belt conveyor 20 and the guide roller 30 in a state where the leaves are pulled in. You will be guided to the side of.

The guide roller 30 is provided on the belt conveyor 20.
Is located on the downstream side in the conveyance direction of the belt conveyor 2
0, and a cutter 4 near its end.
0 is arranged. The cutter 40 is a guide roller 3
It is arranged along the axial direction of the guide roller 30 on the upstream side of the belt conveyor 20 in the transport direction from 0, and is orthogonal to the axial direction of the guide roller 30.

The belt conveyor 20 is connected to the cutter 40.
On the upstream side in the transport direction, a falling plate 63 is provided that extends in an inclined state to the side of the belt conveyor 20 along the cutter 40. In the falling plate 63, the side edges in the direction perpendicular to the direction in which the ginseng body flows down are bent upward to form side walls 64 and 65, respectively.

Below the falling plate 63, a support mechanism 50 is provided.
The storage box 66 supported by the is arranged. The ginseng with leaves conveyed along the guide roller 30 has its leaves cut by the cutter 40, the ginseng main body flows down along the falling plate 63, and is stored in the storage box 66 supported by the support mechanism 50. It is thrown into.

FIG. 2 is a sectional view showing the supporting mechanism 50 of the storage box into which the ginseng main body is inserted. As shown in FIG. 2, the support mechanism 50 has a pair of support arms 51 and a support table 52 which is connected to a lower end of each support arm 51 at a right angle so as to extend outward. . Each support arm 51
The upper end is rotatably attached to the bracket 18. The bracket 18 extends horizontally from the gantry 19 of the traveling vehicle 10 below the downflow plate 63 and is bent upward. On the support table 52, a housing box 66 in which the ginseng main body whose leaves have been cut is stored is placed with its opening facing upward.

The base 19 of the cylinder type shock absorber 53 is rotatably supported on the mount 19 of the traveling vehicle 10. The shock absorber 53 is, for example, expanded by a spring provided therein, and the shock absorber 53 contracts when a compressive force is applied. The shock absorber 53 is not limited to such a spring type and may be a hydraulic type or the like. The tip of the shock absorber 53 is rotatably attached to the lower end of the arm 51 that supports the support table 52. Accordingly, when the empty storage box 66 is placed on the support 52, the shock absorber 53 is in the most extended state. In such a state, the support 52 is attached to the lower edge of the falling plate 63. At the close position, it is in an inclined state substantially orthogonal to the downflow plate 63. The buffer 53 includes a support 52
When the weight of the object placed on top increases, the length in the axial direction contracts in proportion to the weight of the object, and when the shock absorber 53 is in the most contracted state, the support 52 is placed in a substantially horizontal state. Become.

The carrot harvester having such a configuration operates as follows. The ginseng with leaves placed on the ginseng placing table 13 of the traveling vehicle 10 is sequentially transferred onto the driven belt conveyor 20. When the carrots conveyed by the belt conveyor 20 come into contact with the guide roller 30 rotating in a predetermined direction, the leaves are drawn into the gap between the belt conveyor 20 and the guide roller 30.
Thereby, the ginseng main body is in a state orthogonal to the guide roller 30 and the belt conveyor 20 along the guide roller 30.
It is moved to the side of.

When the ginseng main body reaches the side edge of the belt conveyor 20 in this manner, the leaves are guided to the cutter 40, and the cutter 40 causes the base end of the leaves closer to the ginseng main body. Be cut off.

The ginseng main body whose leaves have been cut is placed on the falling plate 6.
