Description

  The present invention relates to a device that can be mounted on a self-propelled device such as a tractor and fertilized while composting fertilizer such as compost, and more specifically, in the case of fertilizer with a high water content, there is no need to clog the conveyor. It is a fertilizer that can be applied at the same time.

  Conventionally, the thing of patent document 1 is proposed as a fertilizer application apparatus used in the field with large ridge intervals, such as sugarcane. This is a method in which the fertilizer in the stirring tank is sent out to the left and right dropping ports by a spiral body, and further, the fertilizer dropped from the stirring tank is sent to the discharge port by screw means.

  However, in the fertilizer application disclosed in Patent Document 1, when the amount of water contained in the fertilizer becomes 45% or more, the fertilizer stirred in the stirring tank becomes clay-like, and it is difficult to send the fertilizer by the screw blades. There was a risk that fertilization could not be carried out smoothly.

  Therefore, in order to solve the above problem, the applicant of the present invention conveys the fertilizer in the lower layer in the storage unit toward the discharge port by the bottom conveyor, and always keeps the fertilizer that tends to stay near the discharge port by the wall conveyor. Therefore, we have developed a fertilizer application system that can apply fertilizer smoothly and in an appropriate amount at all times, even if it is a fertilizer with a high water content.

  Although this fertilizer is advantageous for spreading fertilizer with a high water content, the structure is somewhat complicated, and it takes time and labor for maintenance and inspection, so a fertilizer with a simpler configuration has been desired.

Specifically, the stirring shaft 5 is provided with a spiral stirring blade 51 via a support rod 52 provided to project radially. The agitation shaft 6 is provided with an auger-like agitation blade 61 for agitating and pushing out the contents in the hopper 1. These agitating blades 51 and 61 are both provided so as to be symmetrical with respect to the central portion of the agitating shafts 5 and 6. Specifically, in the upper stirring shaft 5, the direction of the stirring blades 51 is formed symmetrically so that the contents move in the direction of the arrow in the figure from both ends to the center. In the lower agitation shaft 6, the direction of the agitation blade 61 is set symmetrically so that the contents move from the center to both ends while being agitated in the direction of the arrow in the figure.

  The state of stirring and movement of the contents in the hopper 1 by the stirring blades 51 and 61 having the above configuration is as follows. First, the fertilizer of the contents stirred by the stirring shaft 5 is scraped from the front rear side in the hopper 1 to the center side. As a result, the fertilizer scraped to the center side of the hopper 1 concentrates on the stirring shaft 6. The fertilizer concentrated on the stirring shaft 6 moves into the discharge passage 11 by its own weight, and moves as it is being scraped in the discharge passage 11 toward the discharge port 12 by the stirring shaft 6 as it is. And finally, it is discharged from the discharge port 12 to the left and right of the hopper 1 and sprayed.

  Thus, the fertilizer in the hopper 1 moves so as to be always concentrated on the discharge path 11 by being scraped from the front and rear to the center by the stirring shaft 5, and then moved into the discharge path 11, It is pushed out by the stirring shaft 6 in the direction of the discharge port 12 and discharged. By the above stirring and discharging operation, even in the case of a fertilizer having a high water content, there is no fear of staying near the discharge port or clogging, and it is possible to apply fertilizer smoothly and in an appropriate amount at all times.

  Hereinafter, transmission of power from the external drive means will be described. The power transmission means is not limited to the following embodiment, and other known methods may be used.

  The power (rotational force) transmitted from the external power such as the PTO shaft to the joint 4 is transmitted from the pulley P2 attached to the end of the joint 4 to the pulley P1 via the chain C1. As the pulley P1 rotates, the rotating shaft 7 that supports the pulley P1 rotates. The power transmitted to the rotating shaft 7 is transmitted from the pulley P4 to the pulley P3 of the gear box 8 through the chain C2. The power transmitted to the pulley P3 is converted by the gearbox 8 in the direction of the rotation axis by 90 degrees, and is transmitted from the pulley P5 to the pulley P6 via the chain C3. As the pulley P6 rotates, the stirring shaft 6 that supports the pulley P6 rotates.

  Further, the power transmitted to the pulley P9 is transmitted to the pulley P10 via the chain C5. Power is transmitted from the pulley P10 to a pulley P8 provided coaxially, and further transmitted from the pulley P8 to the pulley P7 via the chain C4. As the pulley P7 rotates, the stirring shaft 5 that supports the pulley P7 rotates. With the above configuration, power from the tractor or the like is transmitted to the shaft in the hopper 1.
