(Omitted) so that it is always lifted upward, and as soon as the weight of root vegetables K and the like is applied, it will descend downward.

[0005]

However, the relation between the rubber droop 11 and the locking projection 10 in the root vegetable harvester having the above-mentioned structure has the following problems. That is, as shown in FIG. 3, since the recess 12 is provided so that the rubber dripping 11 and the locking projection 10 for conveyance do not interfere with each other, the locking projection 10 enters the recess 12 of the rubber dripping 11. While there is no gap during the time, the locking protrusion 10 passes through the rubber droop 11,
The recess 12 becomes a gap until the next locking projection 10 passes. Then, as shown in FIG. 4, the rocking container 8
If the rubber drips 11 and the bottom of the rocking container 8 are collected at the beginning of storing the carrot, there is a problem that the tail side of the carrot is thin and the tail is caught in the gap.

[0006]

Therefore, according to the present invention, the root vegetable K is pulled out from the field on one side of the traveling machine body 1 and conveyed to the rear of the machine body, and the root portion after cutting the leaves of the root vegetable machine is supplied to the conveyor A2.
In a root crop harvester that is dropped onto the feed conveyor A2 by a transverse feed roller A3 that is diagonally arranged on the supply conveyor, the vertical and horizontal directions of the conveyor belt of the selection conveyor A4. A plurality of partial projections are provided on the body, and a rubber droop 11 provided with a notch corresponding to the partial projections is provided on the machine body, and the intervals between the partial projections are equal to each other in the vertical and horizontal directions. By setting the interval to be equal to or less than the length of the root vegetable, the root vegetable harvester is prevented from clogging the root vegetable.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIG. FIG. 5 corresponds to the sorting conveyor A4 in FIG. 3 which is a conventional example. The same reference numerals are used for the same members as in the conventional example. The conveyor belt 9 of the sorting conveyor A4 has a plurality of partial protrusions 13, 13 ...
Are arranged vertically and horizontally. And the lateral protrusions 13,
The interval between 13 is such that a small carrot n straddles. Further, on the tip end side of the sorting conveyor A4, a rubber drip 11 having a recess 14 at a position corresponding to the partial projection 13 of the conveyor belt 9 is provided in the machine body 1. The rubber drips 11 function as a buffer or a guide when the carrot n conveyed by the sorting conveyor A4 is accommodated in the rocking container 8 provided in the traveling machine body 1.

Next, the operation will be described. As shown in FIGS. 1 and 2, the root vegetable K is pulled out from the field on one side of the traveling machine body 1, conveyed to the rear of the machine body 1, and the root portion K2 after the leaf portion of the root vegetable is cut is dropped onto the supply conveyor A2. A transverse feed roller A3 is obliquely arranged on the supply conveyor A2.
2 It conveys to the sorting conveyor A4 arrange | positioned on the side.

As shown in FIG. 5, the root portion K2 conveyed onto the sorting conveyor A4 is rubbed with a rubber 1 by a partial projection 13.
It is conveyed in the direction of 1. Here, the root portion K2 is guided while being buffered by the elastic force of rubber, and is housed in the rocking container 8. As described above, the rocking container 8 is normally springed up by the spring so as to easily receive the root portion K2. Rubber dripping 1 at the beginning of storing in the rocking container 8
1 and the rocking container 8 accumulated on the bottom of the container 8, the root side, for example, the tail side of carrot, was thin, so that the tail had entered the gap as in the conventional example (FIG. 4), but as shown in FIG. Since it was made a different structure, the gap becomes smaller,
The conventional problems are solved.

[0010]

As is apparent from the above embodiments, the present invention smoothes root vegetables such as carrots conveyed to the sorting conveyor and the like when moving from the sorting conveyor to the rocking container due to rubber dripping. It can be accommodated in the container. A plurality of recesses 14 are provided in the rubber droop, and by fitting the recesses 14 with partial protrusions provided on the conveyor belt of the sorting conveyor, the gap between the sorting conveyor and the rubber droop is reduced. , There is no room for roots, such as carrot tails, to get into the gap.
