BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a walk-behind fertilizer applicator capable of fertilizing not only on both sides of an in-field passage but also on one side thereof and capable of adjusting the spread reach of fertilizer.

[0002]

2. Description of the Related Art Conventionally, a broadcaster or a manual fertilizer sprayer driven by power from a machine such as a riding tractor has been known, and fertilizer is put into a fertilizer hopper and dropped by a fixed amount. It was configured to be scattered and scattered in the horizontal direction by a fan or the like.

[0003]

However, in the prior art, the direction of spraying fertilizer is rearward in the case of a broadcaster and frontward in the case of a manual spreader, and its adjustment width is very small. However, when fertilization on only one side at the edge of the ridge is sufficient, there is a drawback that it cannot be applied. In addition, since the rotation speed is changed by adjusting the spraying distance of fertilizer, it is not possible to make a large adjustment in the case of a broadcaster, and it is very difficult to keep the rotation speed constant in the case of human power.

[0004]

The present invention comprises the following means in order to solve such problems. That is, in a walk-type fertilizer applicator that drives a feeding device by the rotation of a drive wheel to spray fertilizer, two sets of feeding devices are arranged in the front-rear direction, and a shutter that can be opened and closed is provided on the upper portion of the feeding device to select the fertilizer. And a drop chute is provided in the lower part of the feeding device so that the fall position can be adjusted. Fans are arranged below the both drop chutes. The fans are driven by a motor to change the rotation speed of the motor. It is possible to change the flying distance.

[0005]

[Operation] Next, the operation will be described. That is, hoppers are arranged at the upper parts of the two sets of feeding devices provided in the front-rear direction, the hopper lower shutters provided at the bottoms of the respective hoppers are opened, the fertilizer is fed by the rotation of the feeding rolls, and the angle is set by the drop chute. You can change it and let the fertilizer fall on the fan and spray it in the desired direction,
By opening and closing the lower shutter of the hopper, fertilizer can be selectively applied to both sides or one side of the field, and the spraying reaching distance is adjusted by changing the rotation speed of the fan.
