Description

[0001]
[Industrial application fields]
The present invention relates to a fertilizer spreader mounted on a tractor or the like, and relates to a configuration in which a plurality of types of fertilizers can be mixed in a hopper.
[0002]
[Prior art]
Japanese Utility Model Publication No. 4-53231 is known as a fertilizer spreader that throws a plurality of types of fertilizer into a hopper, mixes these fertilizers in the hopper, and spreads the fertilizer on a predetermined field.
In this fertilizer spreader, a plurality of arms are attached to the axial center of a substantially cylindrical hopper, and a stirring blade having a rake angle is provided. A plurality of fertilizers are mixed by rotating the stirring blade. It is discharged from the feed opening of the slab and is intended to spread a wide width with a rotating spray plate.
[0003]
[Problems to be solved by the invention]
According to a known technique, mixing is performed while lifting the fertilizer with a stirring blade having a rake angle, and it takes time to mix the bottom surface of the hopper and the upper layer portion. Moreover, since it discharges | emits from one feeding opening after mixing, there exists a restriction | limiting in the discharge amount per unit time, and it is not suitable to sow thickly on a straw.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, it can be attached to a tractor, which is a traveling vehicle, and the agitator formed in a ribbon-shaped spiral on a U-shaped hook at the bottom of the horizontally long hopper where fertilizer can be charged and stored constitutes a stirring section for transferring stirring and internally provided a rotating shaft having a blade raw material in one direction, the front and rear adjacent and parallel to the stirring section as the transfer direction of the agitating portion is opposite to each other two provided, at each end of the transport direction of the stirring unit, as well as configured material is continuously circulated provided adjacent each other of the trough to feed scooping member movable to each axis of rotation, Discharge ports were respectively provided on the bottom surface in the transfer direction of the agitator, and a plurality of the discharge ports were provided on the end side in the transfer direction with respect to the length of the ridges so that they could be opened and closed over a half length. The fertilizer spreader characterized by the above is provided. In addition , a flexible fertilizer guide tube is inserted and installed at the shutter opening where the discharge port can be opened and closed, and a fertilizer outlet portion below the guide tube is provided at the lower part of the hopper. The fertilizer spreader as described above, which can be fixed at an arbitrary position of the horizontal support material, is provided.
[0005]
[Action]
As described above, a stirring part that moves while stirring in one direction to a U-shaped bowl is configured, and stirring is performed by continuously circulating in combination in opposite directions, so that high-speed stirring is possible, and stirring is performed when spraying. Since it is discharged and sprayed directly from the bottom surface of the U-shaped ridge, smooth mixing and spraying work can be performed with little compression action and bridge of the mixed fertilizer. Furthermore, since the discharge ports are respectively provided over the length of one half in the width direction on the end side in the transfer direction of the basket, the discharge can be performed until the fertilizer residue is minimized, so that no fertilizer is wasted.
