Description

  The present invention relates to a self-propelled fertilizer spreader, and relates to a configuration in which a plurality of types of fertilizer can be mixed in a hopper and sprayed in a streak shape or a strip shape.

As a background art, a fertilizer spreader that inputs a plurality of types of fertilizer into a hopper, mixes these fertilizers in the hopper, and spreads the fertilizer on a predetermined field is provided with a plurality of There is an agitator blade with a rake angle attached to an arm, and this agitator blade rotates to mix a plurality of fertilizers, and after mixing, discharge from one feeding port and try to spread a wide width with a rotating spray plate. It is known. (Patent Document 1)
Japanese Utility Model Publication 4-53231

  According to a known technique, when mixing, the fertilizer is mixed while being lifted by a stirring blade having a rake angle, and it takes time to mix the bottom surface of the hopper and the upper layer portion. In addition, after mixing, it is discharged from a single feed outlet and spreads and spreads widely using a rotating spray plate. There is a case where waste is also applied to the part. For this reason, the self-propelled manure spreader which can mix a fertilizer in a short time and can carry out a streak-like or strip-like dispersion is provided.

  In order to solve the above-mentioned problems, a rotating shaft having stirring blades is provided in a U-shaped bowl to constitute a stirring unit that transfers fertilizer while stirring in one direction. A pair is installed adjacent to each other in the opposite direction, and a scraping material capable of moving the fertilizer is provided on the ridge adjacent to the end in the transfer direction so that the fertilizer is continuously circulated. A plurality of outlets are provided on the bottom of the end side, and a shutter plate for adjusting the amount of fertilizer falling is provided in close contact with the outlet, and the outlet provided for each outlet of the shutter part is flexible. The guide tube is configured such that the distal end portion of the guide tube can hold a plurality of guide tubes individually or in desired positions of the lateral support material provided over the longitudinal direction of the U-shaped ridge. The fertilizer spreader is characterized by the fact that the fertilizer spreader is mounted on a self-propelled cart. Those that provided the machine. The fertilizer spreader is characterized in that a plurality of discharge ports are provided over the length of one half of the length of the hook at the end side in the transfer direction with respect to the length direction of the hook. is there.

  As described above, a stirring portion that moves while stirring in one direction to a U-shaped bowl, and a scraping material in which fertilizer can move to the adjacent bowl at the end in the transfer direction by combining them in opposite directions to each other Since it is continuously circulated and stirred, a smooth flow of fertilizer is formed, enabling high-speed stirring, and when spraying, it is discharged and sprayed directly from the bottom of the U-shaped bowl of the stirring section, Smooth mixing and spraying work with few bridges. Furthermore, since the discharge port extends over a length of 1/2 on the end side in the transfer direction of the koji, it can be discharged until the fertilizer residue is minimized, so there is no waste of fertilizer.

  In addition, a flexible guide tube is provided in the drop port provided in the shutter plate for adjusting the fertilizer fall amount of the discharge port, and the tip of the guide tube is at a desired position in the longitudinal direction of the U-shaped ridge. Since each can be attached independently, for example, when the guide tube tip is attached to the planting ridge part of the crop, it can be sprayed only on the planting ridge part, and fertilizer is applied only to the necessary part. Can be sprayed in streaks or strips, so fertilizer is not wasted. Furthermore, since it is mounted on a self-propelled cart, the whole can be made compact, and fertilizer can be efficiently distributed in a narrow place such as greenhouse pipe house cultivation.
