The shape and structure of the frame 30 as described above is not limited to Figs. 1 and 2, it is sufficient to be made of a shape and structure that can be selectively coupled to the agricultural machinery by fixing the rope spraying unit 50. .

Next, the row sprinkling spraying unit 50 is for spraying two rows of fertilizer on the outside, that is, soil, and is fixed to the frame 30.

Here, the rope spraying unit 50 is composed of a hopper 51, a striking unit 55 and a two-way screw 57 and a shutter (59 of FIG. 3) as shown in FIG.

More specifically, the hopper 51 is fixed to the frame 30 to accommodate the fertilizer, as shown in Figure 2 is formed with two fertilizer discharge ports 53 on both sides of the bottom, The shape of the fertilizer discharge port 53 is not necessarily limited to the drawings.

In addition, the shape and structure of the hopper 51 is not limited to FIG. 2, but is sufficient if the shape and structure of the hopper 51 is fixed to the frame 30 to accommodate the fertilizer.

Next, the striking portion 55 is installed in the hopper 51 in the lateral direction to strike and crush the fertilizer accommodated in the hopper 51, as shown in Figure 2 the third pulley ( It is rotated by 41 to hit the fertilizer accommodated in the hopper (51).

In other words, when the agricultural machine 5 is operated once, the operation time is finely pulverized, the two-row spraying of the fertilizer, the formation of the pits and the coating of the vinyl on the pits are performed at the same time. There is an advantage that can be shortened significantly more.

As described above, by selectively spraying two rows of the fertilizer spraying the fertilizer, which is fixedly installed on the frame, there is no fear that the fertilizer is sprayed to the place where the fertilizer is unnecessary so that the soil is not consumed by the unnecessary fertilizer. Of course, there is no fear of contamination, and the shutter selectively opens and closes the space of the fertilizer discharge port, thereby enabling the operator to selectively spray the fertilizer as much as necessary to spray two rows of fertilizer.

In addition, since the rotary grinds the soil finely, there is no fear that the soil becomes more hardened by the load of the agricultural machine, and the soil and the fertilizer may be more easily mixed.

In addition, one end of the hydraulic cylinder provided in the upper portion of the rotary shaft is coupled to the connecting member formed on the frame and the length is selectively elongated, so that the rope spraying part fixed to the frame if necessary, from the soil to the upper direction At the same time, the agricultural machinery can be operated while rotating a certain height, and at the same time, the center of gravity of the agricultural machinery is moved in the forward direction of the agricultural machinery, so that the operator can operate the agricultural machinery more safely and the mobility of the agricultural machinery is remarkable. There is an effect that can be improved.

Further, since the shutter selectively opens and closes the space of the fertilizer discharge port by the lever provided on the hopper and rotates in the front and rear direction, an operator can more easily open and close the space of the fertilizer discharge port using the shutter. There is an effect that becomes possible.

In addition, the spray direction control unit is selectively mounted on the lower end of the fertilizer discharge port so that the fertilizer is sprayed two lines to the outside through the fertilizer discharge port is selectively sprayed in the front direction or the rear direction of the rotary, so that the operator as needed The fertilizer has the effect of being able to spray two lines on the ground or ground before grinding.
