(Patent Document 1)
JP 2003-235318 A

  According to a known technique, fertilizer is continuously circulated in a horizontal direction in a pair of adjacent U-shaped bowls and mixed, and a discharge port is provided on the bottom of each bowl, and the fertilizer is dropped from the discharge port. Since it is spread, the spread width is maximum and the hopper width is spread, which is disadvantageous when spread over the entire area.

  For this reason, it is a fertilizer spreader which can mix a fertilizer efficiently in a short time, Comprising: The fertilizer spreader which can be diffused and spread is advantageous when spread over the entire surface.

In order to solve the above problems, a rotating shaft having a stirring blade is provided in a U-shaped bowl to constitute a stirring unit that transfers fertilizer while stirring in one direction, and the transfer directions of the stirring unit are opposite to each other. The first stirring unit and the second stirring unit configured so as to be in the direction are provided adjacent to each other, and a scraping material capable of moving the fertilizer is provided in the basket adjacent to the end in the transfer direction so that the fertilizer is continuously circulated. And a discharge port is provided in the middle part in the front-rear direction of the first stirring part and the second stirring part in the left and right middle part of the spraying work progress direction orthogonal to the transfer direction of the stirring part. 2 Rotate the agitator part so as to scoop up inwardly adjacent to each other, and install a rotating spray plate in which a disc provided with spray vanes is rotatable in the horizontal direction below the discharge port, and dropped from the discharge port It is characterized by having a spreading part that spreads and spreads fertilizer with a rotating spreading plate To provide a fertilizer spreader.

  In order to solve the above problem, in the invention according to claim 2 of the present invention, in the fertilizer spreader, in order to further increase the efficiency of continuous circulation of the fertilizer, A fertilizer spreader is provided in which auxiliary stirring blades formed into a ribbon-like spiral are provided in two rows with the mounting phases of the stirring blade starting end and the starting end being shifted.

  In order to solve the above problem, in the invention according to claim 3 of the present invention, in the fertilizer spreader, in order to more smoothly send the flow of fertilizer sent to the discharge port, the stirring blades of the fertilizer discharge port portion Provides a fertilizer spreader provided with a scraping plate that scrapes the fertilizer to the discharge port.

  As described above, the agitation unit is configured to transfer while stirring in one direction to the U-shaped ridge, and the fertilizer can be moved to the adjacent ridge at the end of each transfer direction by combining the transfer directions in opposite directions. Since a continuous scraping material is installed and stirred continuously, high-speed agitation is possible.Further, the fertilizer in the agitation section is always moving during spraying, so there is little compression action and bridging of the mixed fertilizer and smooth mixing and spraying work is possible. It is possible to provide a discharge port in the middle part of a set of stirring units in a direction perpendicular to the transfer direction of the stirring unit, and to rotate the stirring unit so as to scoop up inwardly adjacent to each other and to fertilize each other at the discharge port As a result, the fertilizer is always supplied evenly from the two agitation units that are transported in the opposite directions so that uniform spraying can be performed to the end.

  In the invention according to claim 2 of the present invention, the fertilizer is moved to the adjacent paddle by the scraping material provided at the end in the transfer direction of the stirring blade, but the start end side in the transfer direction of the stirring blade on the receiving side A stirrer blade formed into a ribbon-like spiral is provided in two strips with the mounting phase of the start end shifted, and the transfer efficiency on the start end side on the receiving side is increased, so that the fertilizer can easily move to the adjacent paddle. A smooth flow of water is formed to improve the efficiency of continuous fertilizer circulation.

  Moreover, in invention of Claim 3 among this invention, by providing the scraping board which scrapes a fertilizer to a discharge port part in the stirring blade of a fertilizer discharge port part, the fertilizer sent to a discharge port is more efficient until the last. Can send well.
