SUMMARY OF THE INVENTION The above-mentioned prior art has a
Does the belt extend in a straight line in the direction of the aircraft
Et al., Are released to the location where the root has been pulled out, and the non-harvest location
It is necessary to secure a running space between the released root vegetables.
For this reason, a chute for traverse was provided.
Release after sending in the horizontal direction by the width of the left and right of large aircraft such as
There is a problem that it is not possible to easily configure a structure that performs the above. Also,
The feed end side of the conveyor belt is bent horizontally and extended
By using a conveyor belt to pull out root vegetables,
Root vegetables are released to a location away from the place, and
Easily secure a traveling space such as a tractor between the root vegetable discharge locations.
Can be maintained, but the bending angle of the intermediate corner of the conveyor belt is small.
Doing so may prevent root vegetables from clogging or damage at the transport corner.
The bending angle of the intermediate corner of the conveyor belt
The greater the degree, the larger the width of the conveyor belt in the front-rear direction.
And the support structure becomes complicated or the front-rear balance is poor
There is a problem .

[0004]

According to the present invention, however, the present invention comprises a vibrating digging blade , two inner and outer conveyor belts, and a root crop.
Root vegetables harvesting machine that is pulled from
After pulling out from the field, move the transport path
Is formed to extend in a substantially straight line in the
Lateral conveyance with the end of the conveyor belt extending in the lateral direction of the machine
Form a path and start the end of the post-transportation path and start feeding the horizontal conveyance path.
L-shaped corner part connected to the end
Two inner drive pulleys are provided to convey the conveyor belt
Stretching the corner during feeding via two inner drive pulleys
And the non-conveyance between the feed start and end of the inner conveyor belt.
An outer drive pulley is provided on the feeding side to transport outside the corner.
Formed so that the holding and conveying part of the belt is on the loose side of the drive
, Depending on the post-transfer path that extends in the machine
Pull out the root vegetables almost vertically to prevent damage when pulling out
Root vegetables are obtained by the horizontal transport route extending in the horizontal direction of the machine.
To the position away from the pull-out place,
And the two inner drive pulleys
To bend the inner conveyor belt corner in multiple steps.
And, the larger form root pivot angle in cornering portion notwithstanding
Corner angle of the conveyor belt can be formed small,
It can eliminate the problem of root vegetables getting clogged or damaged at the corners,
In addition, the width of the conveyor belt in the front-rear direction is
The problem that the structure becomes complicated or the front-rear balance becomes poor
Drives outer conveyor belt at corners
