[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, when mounting a chute, the upper end of the chute 26 is clamped and fixed to a base 29 by a pressing plate A. Reference numeral 21 is a lifting conveyor having a loading protrusion 21a, and 22 is a conveyor for carrying the fallen root vegetables C from the lifting conveyor 21.

[0003]

However, in the case of the above-mentioned conventional technique, since the hard pressing plate is arranged on the chute, the root vegetables falling from the feeding conveyor drop and collide with the hard pressing plate. There is a possibility that the root vegetables will be damaged due to the drop collision with the pressing plate, especially when the falling plate collides with the corner of the pressing plate.

An object of the present invention is to prevent damage to the root vegetables from the lifting conveyor by devising the attachment of the chute.

[0005]

The structure, operation and effect of the first invention according to the first aspect of the present invention are as follows.

[Structure] When mounting the chute, the scooping tool is inserted into the upper end of the chute from below to support the chute.

[Operation] Since the scooping tool is inserted through the upper end of the chute from below and the chute is supported by the scooping tool, it is of course not necessary to dispose a pressing plate or the like on the chute. The upper end of the chute is tilted with respect to the scooping tool by inserting the scooping tool, so that the upper half of the chute lifts up in a round shape and the upper half of the chute is elastically deformed downward. As a result, it is possible to expect not only the shock absorption by the elasticity of the chute itself but also the high-performance shock absorption by the elastic deformation of the chute when catching the fall root vegetables. Moreover, since the chute is attached only by inserting the originally provided scooping tool into the upper end portion of the chute, a member for attaching the chute such as a pressing plate is unnecessary.

[Effect] As a result, according to the present invention, it is not necessary to provide anything on the chute that damages the fall root vegetables, and the effect of absorbing the drop impact of the chute itself can be improved, whereby the fall root vegetables are combined. It is possible to receive the spillage without damaging it and to supply the spillage down to the conveyor, and to simplify the chute mounting structure and facilitate the mounting work.
