The grip part 100 is a member for gripping the bulbous crop. The grip unit 100 may include a grip body 110 constituting the body, a grip finger 120 connected to the grip body 110 , and a grip actuator 130 that operates the grip finger 120 .

At least a portion of the rear end of the grip body 110 may be connected to the body 200 through the body shaft 112 . Accordingly, the grip body 110 may rotate in the vertical direction about the body axis 112 . At this time, according to one embodiment, the body shaft 112 may be provided with a connection pulley 114 in which a connection line 136 to be described later can be surrounded.

The grip finger 120 is connected to the grip body 110 . Accordingly, the grip finger 120 may be pivoted in the vertical direction together with the grip body 110 . Two grip fingers 120 may be provided symmetrically left and right. The rear end of each grip finger 120 is pivotably connected to the grip body 110 about the finger axis, respectively. Accordingly, the grip fingers 120 are pivotably connected in the left and right directions on a horizontal plane. When the grip fingers 120 pivot, the gap between the grip fingers 120 may be narrowed or widened from each other. That is, the grip fingers 120 may operate in a closed state in which the distance between the grip fingers 120 is narrowed and in an open state in which the gap between the grip fingers 120 is widened.

The grip finger 120 may have a clamping forceps structure to stably grip the stem of the bulbous crop. This clamp clamp structure can be quickly made to clamp and release the clamp.

According to a specific example, the grip finger 120 may be provided with teeth. Accordingly, it is possible to stably and firmly grip the bulbous crop.

Further, according to a specific example, the grip finger 120 has a configuration in which at least a portion of the end portion can cross each other. That is, for example, one grip finger 120 may include a protrusion, and the other grip finger 120 may include a depression in which the protrusion of the one grip finger 120 is interpolated. Accordingly, it is possible to stably grip a bulbous crop having a small diameter.

A first gear portion 124 may be provided on the rear inner surface of the grip finger 120 (the surface on which the grip fingers 120 face each other).

The grip actuator 130 is a member that operates the grip finger 120 .

The connection line 136 is a predetermined line connected to the rear end of the grip actuator 130 , and may be, for example, a device such as a wire. When a force pulling the connection line 136 is applied to the rear, the grip actuator 130 may be displaced rearward. On the other hand, if the pulling force as described above is removed, the grip actuator 130 may be restored forward.

At this time, according to one embodiment, as described above, the grip body 110 may be provided with a connection pulley 114 . The connection line 136 may be surrounded by the connection pulley 114 to extend forward and backward of the connection pulley 114 .

The first toothed portion 124 and the second toothed portion 133 may be meshed with each other.

Accordingly, when the grip actuator 130 is displaced forward, the grip finger 120 pivots about the grip axis. At this time, the grip finger 120 is in a closed state.

Conversely, when the grip actuator 130 is displaced rearward, the grip finger 120 pivots about the grip axis. At this time, the grip finger 120 is in an open state.

According to an embodiment, a predetermined elastic member for elastically biasing the grip finger 120 to an open state or a closed state may be provided. A specific shape of the elastic member is not limited. For example, according to the embodiment, an elastic member for elastically tireing the grip finger 120 in an open state may be provided. In this case, when a force for retracting the connection line 136 is generated, the grip finger 120 may be closed. However, when the force is removed, the grip finger 120 may return to the open state by the elastic member.
