When the inlet of the fertilizer bag B is expanded and gripped as shown in FIG. 5D, the cylinder 243 is operated, and the arm 221 is vertical because the rack 242 connected to one end thereof rotates the pinion 241. As it rises, the inlet of the fertilizer bag B is dragged to the lower side of the clamp 410 (see FIG. 5E).

On the other hand, as can be seen in Figure 5d, when the fixture 411 and the rotating body 412 of the clamp 410 is in the preparation stage, the conveyor 302 is not operated, in this case fertilizer (F) Since the fertilizer supply plate 305 in front of the conveyor 302 is located perpendicular to the conveyor 302, the fertilizer (F) does not fall into the hopper of the metering means (400).

In other words, the conveyor 302 and the cylinder 310 and the link 311 are operated at the same time the gripping operation of the fertilizer bag (B) is made. Accordingly, as shown in FIG. 5E, when the fertilizer bag B moves to the clamp 410 as shown in FIG. 5E, the conveyor 302 is operated and the fertilizer supply plate 305 is operated. The silver is opened by the cylinder 310 and the link 311, so that the fertilizer drops quantitatively in the metering means (400).

Thus, in order to accurately fertilize the fertilizer by a predetermined amount, the present invention includes a load cell 402 as shown in FIG. 5F, and one end of the load cell 402 is connected to the hopper 401 by a fixture 402A, and the load cell The other end of 402 is connected to the frame 100 by a fixture 402B. Therefore, when the fertilizer is first supplied, the fertilizer supply plate 305 is opened wide as shown in FIG. 5E, and when the fertilizer supply amount is gradually reached, the fertilizer supply plate 305 is gradually closed as shown in FIG. 5F, and the hopper ( 401) to accurately weigh the fertilizer is filled.

The supply amount (weight) of such fertilizer is electronically sensed by the load cell 402 and transmitted to a controller not shown, which can be operated by operating the conveyor 302 and the cylinder 310.

After the fertilizer is quantitatively metered by the load cell 402, the fixed body 411 and the rotating body 412 of the clamp 410 in the state where the arm 221 opens the inlet of the fertilizer bag B as shown in FIG. 5E. If the inlet of the fertilizer bag (B) in between, the rotating body 412 is opened by the cylinder 414 by the operation of the sensor (not shown), wherein the fertilizer bag (B) is fixed body 411 It is held firmly by the rubber member 413 and the swinging body 412 of the bar, wherein the arm 221 is dropped as shown in Figure 5f.
