Hereinafter, the present invention will be described in detail with reference to the drawings. In the following description, elements corresponding to each drawing may be provided with the same reference numerals even if they have technically different characteristics.
FIG. 1 (A) is an explanatory view in side view showing the configuration of the crop planting mechanism of the present invention. Also,
FIG. 2 (A) is an explanatory view in side view showing the configuration and operation of the pushing rod portion of the crop planting mechanism shown in FIG. In FIG. 2A, the process of crop extrusion is shown from right to left. As shown in these figures, the present crop planting mechanism 100 for planting bulbous vegetables, potatoes, bulbs, and other massive crops is open for temporarily accommodating the crop G before planting. A planting holder 40 having an upper end 40A and a lower end 40B for discharging the crop, and circulation for circulating the planting holder 40 between a storage position where the crop G is stored and a planting position. The mechanism 200, the pushing rod 6 for pushing the crop G downward by being inserted from the upper end 40A of the planting holder 40 when the planting holder 40 is in the planting position, and the pushing rod 6 at the planting position And a vertical movement mechanism 500 for moving the vertical movement. In particular, as shown in FIG. 2 (A), the pushing rod 6 is mainly composed of a pipe 64 and an inner rod 65 provided so as to be movable up and down in the pipe 64.

When the force point portion of the lever member 63 comes into contact with and is locked to the fixed end 639 as shown in the middle figure, the lowering of the pipe 64 provided with the lever member 63 is stopped. On the other hand, the inner rod 65 that can be moved up and down independently of the pipe 64 has a lever action caused by the fixed end 639 in the lever member 63 having an action point in contact with the upper portion thereof, so that the left side of FIG. As shown in the figure, it is lowered independently of the pipe 64. Thereby, the pushing-out action of the center part of the crop G by the internal basket 65 mentioned above is made smoothly and reliably.
