FIG. 3 shows a specific structure of the fertilizer application device.

That is, in the paste tank 40,
In the present embodiment, for example, a high-clay, fast-acting paste fertilizer 38 is stored, and the paste fertilizer 38 is discharged downward little by little from the discharge portion 41 at the bottom of the tank by the action of gravity. Further, the granular tank 44 stores a slow-acting granular fertilizer 42 whose periphery is coated with a special film, and a pay-out roll 45 is provided at a lower portion of the tank. Are fed downward by a predetermined amount.

The mixing means 46 has a transfer conveyor 50 and a stirring section 52. The transfer conveyor 50 has a belt 50a wound between front and rear rollers 51a and 51b, and the belt 50a is a front roller. Drive shaft 4 of 51a
The belt 50a is driven by a motor (not shown) for driving the belt 9 and the feeding roll 45 is interlocked with the belt 50a.

The transfer unit 50 can be closed counterclockwise in the figure with the drive shaft 49 as a fulcrum (shown by a chain line), so that the discharge unit 41 can be closed by a belt 50a. In this state, the movement of the front and rear rollers 51a, 51b and the belt 50a can also be stopped.

The paste fertilizer 38 flowing out of the discharge part 41 spreads thinly on the belt 50a of the transfer conveyer 50 and is transferred by the belt 50a, and immediately behind the discharge part 41 of the paste fertilizer 38. Then, the granular fertilizer 42 is fed out by a predetermined amount from a feed roll 45 and is distributed on the paste fertilizer 38. Thus, the mixed fertilizer (grain-containing paste fertilizer) composed of the paste fertilizer 38 and the granular fertilizer 42 is separated from the belt 50a by the scraper 54 provided at the end of the transfer conveyor 50, and sent to the agitator 52.

The stirrer 52 stirs the paste fertilizer 38 and the granular fertilizer 42 to make the density uniform, and includes a stirrer rod 56 disposed in a stirrer case 52a.
And a motor 58 for rotating the stirring rod 56.
The mixed fertilizer stirred here is sent to the pump 32 side,
The liquid is pumped from the pump 32 toward the pipe 34 and discharged from the nozzle 36 through the indicator / stop portion 48.

FIG. 4 shows an embodiment in which the nozzle 36 is mounted. The nozzle 36 is connected to the connector 35 and the band 3.
It is connected to a conduit 34 by 7 and attached to a float 29 that supports the planting portion 26. The injection depth of the fertilizer can be freely adjusted by operating the depth adjustment lever 39. In this embodiment, the conduit 34
And the inner diameter of the nozzle 36 are substantially the same. As a result, there are no irregularities in the flow channel, and the mixed fertilizer containing grains flows smoothly.

Next, the operation of the present embodiment will be described.

The fertilizer in the fertilizer tanks 30, 30 provided on the left and right rear portions of the driver's seat 22 is pumped by a pump 32 through a pipe 34 to the side streaks of the seedlings transplanted in the field. The mixed fertilizer is injected into a predetermined depth at the center of the side streak or between the streaks of the seedling, for example, at the same time as the planting operation of the seedling, for example, from a nozzle 36 provided below the head. The fertilizer tank 30
Is composed of a paste tank 40 and a granular tank 44 in which a paste fertilizer 38 and a granular fertilizer 42 are individually stored.

Here, a high-viscosity and fast-acting paste fertilizer 38 is placed in the paste tank 40, and a slow-acting granular fertilizer 42 whose surface is coated with a special film is placed in the granular tank 44. In this case, the transfer conveyor 50 shown in FIG.

Then, the paste fertilizer 38 in the tank 40
Flows out of the discharge unit 41 by a predetermined amount by the action of gravity, spreads thinly on the upper surface of the belt 50a of the transfer conveyor 50, and the granular fertilizer 42 drops by a predetermined amount from the payout roll 45 below the granular tank 44 behind. It is sprinkled on the paste fertilizer 38. The paste fertilizer containing granules of the paste fertilizer 38 and the granular fertilizer 42 is scraped by a scraper 54.
The mixture is then separated from the belt 50a and sent to the stirring unit 52, where the mixture is uniformly mixed by the driving of the motor 58, sent to the pump 32, and sent from the pump 32 to the nozzle 36 under pressure.

In this case, since the paste fertilizer 38 and the granular fertilizer 42 are mixed in the stirring section 52, a homogeneous mixed fertilizer can be obtained, and this mixed fertilizer is placed in the subsequent stage of the stirring section 52. By pumping with the provided pump 32, the mixed fertilizer can be fertilized simultaneously and efficiently.

When the fertilizer application operation is stopped, the transfer tank 50 can be rotated in a chain line around the drive shaft 49 of the transfer conveyor 50 so that the paste tank 4 can be rotated.
The 0 discharge port 41 is closed by the belt 50a, and at the same time, the rotation of the feeding roll 45 below the granular tank 44 is stopped. For this reason, the paste fertilizer 3
8 is prevented and the mixing operation is stopped.

[0034]

As described above, according to the present invention, a predetermined amount of each fertilizer is taken out from a liquid tank and a granular tank in which a liquid fertilizer and a granular fertilizer are individually stored, respectively, and mixed. By providing the pump for pumping toward the downstream side of the mixing means, the liquid fertilizer and the granular fertilizer are mixed at the preceding stage of the pump, so that a uniform mixed fertilizer can always be applied to the soil. For this reason, for example, the fertilization of the liquid fertilizer for the initial growth of the crop and the fertilization of the granular fertilizer for the subsequent growth can be simultaneously and efficiently performed.

It is to be noted that if one fertilizer is added from the middle of the pipe, there is a possibility that the liquid fertilizer leaks from the point of the addition and the pumping power of the fertilizer may be reduced. Since the pump is arranged at the latter stage of the mixing means with the fertilizer, there is no risk of fertilizer leaking in the middle of the piping, and the fertilizer can be discharged from the nozzle with a high pumping force.

The mixing means has a transfer section for transferring the liquid fertilizer and the granular fertilizer taken out by a predetermined amount to the pump side, and a stirring section for stirring the liquid fertilizer and the granular fertilizer. Thereby, a predetermined amount of the liquid fertilizer and the granular fertilizer can be taken out and mixed so as to have a uniform density.
