Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a root crop harvesting machine for extracting root crops such as carrots and radishes planted in a field and cutting the foliage.

[0002]

2. Description of the Related Art A conventional root crop harvesting machine is disclosed in Japanese Patent Laid-Open No.
There is one described in 0-178849, and this technique is provided with a rearward rising inclined conveyor belt that conveys backward while pulling out the foliage of root crops planted in a field. On the lower side, a guide mechanism is provided which is composed of a pair of conveyor belts that are arranged in a rearward rising slope that is gentler than the conveyor belt, and a cutter that cuts the foliage is provided behind the conveyor belt and the guide mechanism. Has become.

Then, the root crop is hung and conveyed upward and backward while the foliage portion is sandwiched by the conveyor belt, and is conveyed while sandwiching the vicinity of the root of the foliage portion by the guide mechanism during the transportation. Since the rear rising inclination of the guide mechanism is steeper than the rear rising inclination of the guide mechanism, the foliage is pulled up by the conveyor belt and slides up and down between the guide mechanisms, and the top surface of the root vegetable crop hits the lower surface of the guide mechanism. By contacting them, the root crops could be positioned vertically.

[0004]

In the above-mentioned prior art, since the top surface of the root crop is brought into contact with the lower surface of the guide mechanism, the root crop is reliably positioned vertically and is fed to the cutter in this state. The foliage was able to be cut at a desired cutting height. However, while the conveyor belt and the guide mechanism are inclined rearward and the cutter is also inclined rearward along the guide mechanism, the root crops are conveyed in a hanging posture perpendicular to the ground. Therefore, even if the cutting height is made uniform by the guide mechanism, there is a risk that the cutter will enter the foliage part at an angle, the cuts will be misaligned, and the cutter will cut into the root vegetable crop itself. Was a cause of the deterioration of quality.

The present invention has been made in view of the above problems, and it is possible to change the posture of a root vegetable crop to a posture corresponding to a cutting tool so that the foliage can be cut with a good cut. The purpose is to provide a machine.

[0006]

The present invention takes the following technical means in order to achieve the above object. That is, the harvesting machine according to the present invention is a harvesting machine for root vegetable crops, which is provided with a transport processing section 13 that transports the root vegetable crop S extracted from the field to the cutting tool 50 of the foliage S1. First to convey while holding the foliage S1
A holding portion 24 and a third holding portion 26 that is arranged below the first holding portion 24 and holds the root portion of the foliage S1.
And the first holding part 24 and the third holding part 26 are arranged in parallel, and while carrying the foliage part S1 between the first and third holding parts 24 and 26, the root crop S is conveyed. And a second holding portion 25 for setting the posture of the predetermined posture.

According to this, while the foliage portion S1 is held by the first holding portion 24, the second and third holding portions 25,
26 also holds the foliage portion S1, especially the third holding portion 2
By holding the root portion of the foliage S1 by 6, the root vegetable crop S is positioned up and down, and the second holding portion 25 sets the posture of the root vegetable crop S in a suspended state to a predetermined value. The posture of the root crop S can be changed so as to be perpendicular to the cutting tool 50. As a result, it becomes possible to cut the foliage portion S1 substantially perpendicularly to the root vegetable crop S and at a desired cutting height without the cutting tool 50 obliquely entering the root vegetable crop S.

Further, according to the present invention, the first to third holding portions 2 are provided.
4, 25 and 26 and the cutting tool 50 are arranged in a slanting upward slope, and the first and second holding portions 24 and 25 convey the pair of conveyor belts 2 while nipping the foliage portion S1.
It is configured that the second conveyor belt 30 composed of 0, 30 and constituting the second holding portion 25 is driven at a faster conveying speed than the first conveyor belt 20 constituting the first holding portion 24. It has a feature.

According to this, the first and second conveyor belts 2
The posture of the root crop can be easily changed by the difference in the transfer speed of 0.30, and the root crop S is suitable for the forward leaning posture perpendicular to the cutting tool 50 arranged in the backward rising inclination. The posture can be changed. At this time, it is preferable that the transport speed of the second transport belt 30 is about 1.3 times the transport speed of the first transport belt 20.

According to the present invention, the third holding portion 26 is
A pair of sandwiching members 40 for sandwiching the foliage S1 from the left and right.
The holding member 40 is configured to hold the foliage portion S1 with a holding force weaker than that of the first and second conveyor belts 20 and 30. According to this, by pulling up the foliage portion S1 by the first conveyor belt 20, the foliage portion S1 is easily slipped up and down between the holding members 40, and the lower surface of the holding member 40 surely abuts the top surface of the root crop S. This enables vertical positioning, and when the posture of the root crop S is changed by the second conveyor belt 30, the foliage portion S1 slides between the holding members 40 and the posture is changed appropriately. By sending the root vegetable crop S to the cutting tool 50 arranged at the rear side, more excellent cutting can be performed.
