A U-shaped rotary cutting blade 47 is arranged in a front view (or a back view) constituted by attaching a plurality of L-shaped cutting blades 46.

  In this embodiment, three cutting blades 46 are provided on the rotating portion 45 at intervals of about 120 degrees, but the cutting blades 46 may be increased to three or more. In this case, for example, if four cutting blades 46 are provided, the cutting blades 46 are spaced at intervals of about 90 degrees, and if six cutting blades 46 are provided, the cutting blades 46 are spaced at intervals of about 60 degrees. This makes it possible to efficiently remove the root of the hair.

  Further, a hole formed in a position shifted in phase from the position where the cutting blades 46 are connected is formed on the inner side of the rotating portion 45 with a mounting flange 48 which is fanned so as to have substantially the same shape as the rotating portion 45. It attaches to part 48h ... via fixing members 48v, such as a volt | bolt.

  In this embodiment, the fixing member 48v attached to the hole 48h of the attachment flange 48 is attached with a phase shift of about 60 degrees in the circumferential direction from the position where the cutting blade 46 is connected. In other words, the hole portions 48h for attaching the fixing member 48v are formed at substantially intermediate positions between the two cutting blades 46, 46, respectively.

  If the length or weight of the fixing member 48v for attaching the mounting flange 48 is changed, or the weight or diameter of a nut or washer (not shown) is changed, the rotary cutting blade 47 rotates with inertial force due to the flywheel effect.

The soil adhering to the inner surface of the blades 46 can be dropped, and the cutting performance of the cutting blades 46 can be prevented from being hindered by the adhesion of the soil, thereby preventing the cutting efficiency of carrot roots from being lowered.

  Further, when the inclination angle of the extension cover 54b is an acute angle (about 30 to 60 degrees) and the outer line portion is formed in a slightly curved shape instead of a straight line, the soil poured from above tends to slide down the inclination portion of the extension cover 54b. It is possible to prevent soil from accumulating on the extension cover 54b, and it is not necessary to remove the soil accumulated inside the root cutting device 57, thereby improving maintenance.

  Further, the cutting blade 46 forms a cutting action surface 46a that cuts in contact with the lower root of the carrot, and the non-cutting action surface 46b on the upper side in the conveying direction is directed from the inside of the body toward the outside of the body. And the end of the L-shaped cutting blade 46 on the left and right sides of the machine body (outside the machine body) is formed in a substantially straight line with respect to the rotational direction of the rotary cutting blade 47. To do.

Further, the cutting action surface 46a is positioned above the non-cutting action surface 46b, and the cutting blade 46 is inclined upward from the non-cutting action surface 46b toward the cutting action surface 46a.
In addition, a linear portion 44a is formed on the lower side of the guide cover 44 in the conveyance direction, and is inclined downward from the upper side in the conveyance direction toward the lower side, and the linear portion is formed at the lower end of the linear portion 44a in the conveyance direction.

Since it can be dropped, the carrot is prevented from being damaged by the impact of the drop, and the product value of the carrot is improved.

  Further, when the shooter 79 is rotated upward, it becomes a stopper that closes the terminal end side of the sorting and conveying conveyor 78. Therefore, when exchanging a container full of carrots, the carrot can be moved without stopping the sorting and conveying conveyor 78. Since it is possible to prevent the carrot from falling from the end portion, it is necessary to prevent the carrot from being damaged by the impact of the drop and improve the quality of the carrot, and the power of the sorting and conveying conveyor 78 needs to be frequently turned on and off. The work efficiency is improved.

  Further, since the shooter 79 is turned upward to serve as a stopper and the sorting / conveying conveyor 78 is not stopped, the carrot accumulates on the terminal side of the sorting / conveying conveyor 78. Since the carrots that have been brought into contact with the carrots staying at the conveyance start end of the sorting and conveying conveyor 78 are prevented from being damaged, the product value of the carrots is improved.

  Further, by attaching an operation lever 80 for turning the shooter 79 up and down on the left and right outer sides of the shooter 79, the auxiliary worker can turn the shooter 79 up and down while sitting on an auxiliary work seat 88 described later. The labor of auxiliary workers is reduced.
