And since such a stirring device is arranged between the upper part of the spiral body and the inner wall of the stirring tank, in combination with the rotation of the spiral body, a larger amount of fertilizer is put into the stirring tank, Mass processing is possible.

As in claim 1, the spiral body is supported at the tip of a support bar attached in the radial direction to the horizontal axis in the stirring tank, and the rotation of the spiral body feeds the fertilizer to the discharge port side. The fertilizer in the stirring tank is constantly stirred and pulverized by the rotation of the support bar that rotates together with the spiral body. Therefore, it is possible to spray fertilizer in a pulverized powder state at all times. As shown in FIGS. 2 and 3, the support bar stands in the radial direction with respect to the horizontal axis, and since fertilizer can pass between the support bars, even when a large amount of fertilizer is put into the stirring tank, The problem of overloading does not occur. The spiral body is also attached only to the tip of the support bar, and since it is in the form of a strip or rod, fertilizer can be passed through on both sides, and it does not overload.

Since the direction of the left half and the right half of the spiral body are reversed at the middle of the horizontal axis as in claim 2, the fertilizer can be sent out and sprayed toward the drop ports at the left and right ends. Fertilizer can be applied in the form of large lines.

Since the bottom part of the stirring tank is formed in an arc shape that is slightly larger than the outer diameter of the spiral body, the spiral body also serves as a scraper. The fertilizer can be prevented from adhering and can be uniformly stirred and ground uniformly. In addition, the fertilizer can be quantitatively fed by the interaction between the bottom of the stirring tank and the spiral body.

Since the screw means is provided horizontally in the horizontal duct provided under the discharge port as in claim 4 and the fertilizer discharge port is provided on the delivery side of the screw means, the screw means has fallen from the stirring tank. The fertilizer can be reliably and smoothly delivered to the target discharge port position by the screw means.

As in claim 5, the two rotating shafts are rotated by the output shaft of the tractor, one rotating shaft is connected to the screw means, and the other rotating shaft is connected to the horizontal axis of the helical body. Because of this structure, a single tractor output shaft can drive multiple rotating systems of the fertilizer application.

Since the two stirring horizontal axes are provided in parallel above the spiral body and the radial stirring means is spirally provided on the stirring horizontal axis as in claim 6, the stirring device is configured. Since the fertilizer can pass between the stirring means in the respective radial directions, it is not excessively loaded and can be smoothly stirred and ground. And since such a stirring device is arranged between the upper part of the spiral body and the inner wall of the stirring tank, in combination with the rotation of the spiral body, a larger amount of fertilizer is put into the stirring tank, Mass processing is possible.

Next, an embodiment of how the fertilizer application according to the present invention is practically described will be described. FIG. 1 is a perspective view showing the entire fertilizer application apparatus according to the present invention, in which an upside down stirring tank h is formed in a hopper shape. In the stirring tank h, three horizontal shafts 1, 2, and 3 are supported in parallel with each other, and a spiral body is attached and supported around the lower horizontal shaft 1, and the two upper shafts are supported. On the horizontal shafts 2 and 3, radial stirring bars are arranged and fixed sequentially shifted in a spiral manner.

On the outside of the stirring tank h, two left and right rotating shafts 4 and 5 are horizontally supported in parallel with the horizontal shafts 1 to 3, and the bevel gear in the gear box 6 between the rotating shafts 4 and 5 is attached. And a drive shaft 7 connected to the output shaft of the tractor. A small pulley P1 at the left end of the left rotation shaft 4 is connected to a large pulley P2 for deceleration and a belt B1, and a small gear coaxial with the large pulley P2 and the large gear of the horizontal shaft 1 are connected by a chain. The right end of the horizontal shaft 1 and the right end of the horizontal shaft 2 are connected by a belt or a chain B2, and the left ends of the horizontal shafts 2 and 3 are connected by a belt or a chain B3. Therefore, the horizontal shafts 1, 2, and 3 are rotationally driven by the left rotation shaft 4.

Below the stirring tank h, fertilizer feeding screws are provided on the left end side and the right end side. The right end of the screw shaft is connected to the pulley P3 on the right end of the right rotating shaft 5, the belt, They are connected by a chain B4.

FIG. 2 is a longitudinal cross-sectional view of the stirring tank h in the AA direction. The bottom 8 side of the stirring tank h has an arc shape, and the upper side thereof continues in the form of an open hopper. Reference numerals 9 and 10 denote hopper-like left and right side walls. A support bar 11 is fixed to the horizontal shaft 1 in the stirring tank h in the radial direction as shown in the figure, and a spiral body 12 is attached and supported at the tip of each support bar 11. For example, rod-like stirring means 13 are attached to the upper two horizontal shafts 2 and 3 by sequentially shifting in a spiral manner in the radial direction as shown in the drawing and in the longitudinal direction of the stirring horizontal shafts 2 and 3 as shown in FIG. It is fixed.

FIG. 3 is a perspective view of the inside of the stirring tank h, and shows the spiral body 12 and the stirring means 13. As shown in the figure, the horizontal shaft 1 is at the center position of the spiral body 12 and is connected to each other by radial support bars 11. That is, the base ends of the support bars 11... Are attached and fixed to the horizontal shaft 1, and the spiral body 12 is attached and supported at the tip of each support bar 11. Therefore, each support bar 11... Appears radially around the horizontal axis 1 when viewed from a direction perpendicular to the horizontal axis 1 as shown in FIG. When viewed from the perspective view of FIG. 3 or the side view of FIG. 4, the spiral bodies 12 are spirally arranged so that they can be supported at the tip. Therefore, when the horizontal shaft 1, the support bar 11, and the spiral body 12 rotate in the fertilizer f in the stirring tank h, the fertilizer f relatively passes between the support bars 11 and the spiral body 12. Therefore, the load acting on the support bar 11..., The horizontal shaft 1, and the spiral body 12 is small, and there is no possibility of being unable to drive due to an excessive load, and the rotation can be smoothly performed and stirred and pulverized. In addition, the spiral body 12 has a spiral direction reversed in the right half and the left half.

The rod-like stirring means 13 attached to the stirring horizontal shafts 2 and 3 in the radial direction appear radially when viewed from the direction perpendicular to the horizontal shafts 2 and 3, as shown in FIG. When viewed from the side view of FIG. 4 or FIG. 4, they are arranged in a spiral shape. Therefore, when the horizontal shafts 2 and 3 rotate in the fertilizer f in the stirring tank h, the fertilizer f passes relatively between the stirring means 13. The load acting on the motor is small, and there is no fear of being unable to be driven by an excessive load.

As shown in FIG. 3, in the bottom of the stirring tank h, at the position directly below the horizontal shaft 1 for feeding, the drop ports 14 are opened on both the left and right ends, and the screw 15 can be seen below. FIG. 4 is a longitudinal sectional view of the stirring tank h in the direction of FIG. 1B-B. The left and right end portions of the horizontal shafts 1, 2, and 3 are pivotally supported by the left end wall 16 and the right end wall 17 of the stirring vessel h, and the spiral body 12 supported by the horizontal shaft 1 by the support bars 11. The left and right halves are reversed in a spiral direction. Therefore, when the spiral body 12 rotates, the fertilizer f on the lower side of the stirring tank h is sent leftward on the left side and sent on the right side on the right side.

The bottom wall 8 of the agitation tank h has the above-described drop openings 14 and 14 open on the left and right ends, and the discharge cylinder C is connected to the horizontal shafts 1 to 3 below the left and right drop openings 14 and 14. It is provided in a parallel direction, and screws 15 and 15 are incorporated therein. The screw shafts 18 of both the screws 15 and 15 are continuous with each other, and one end thereof is connected to the right end pulley P3 of the right rotation shaft 5 in FIG. 1 by a belt, a chain B4, or the like. Since the left screw 15 and the right screw 15 are opposite to each other, the fertilizer that has fallen into the discharge cylinders C and C from the dropping ports 14 and 14 is sent to the left side by the left screw 15 and the right screw 15 To the right. Since the discharge port 19 is open under the left end of the left discharge cylinder C, and the guide rod 20 is disposed under the discharge port C, the fertilizer sent by the screw 15 is pushed out from the discharge port 19, It falls into the lower basket 20 and is guided to the target fertilization position. Similarly, the fertilizer sent by the right screw 15 is guided to the target position by the right rod 20.

As is clear from FIG. 4, the left half and the right half of the spiral body 12 are spirals in opposite directions, so that the fertilizer f below the stirring tank h is sent to the left half, It falls from the lower drop port 14 into the left discharge tube C, the right half is sent to the right side, and falls from the lower drop port 14 into the right discharge tube C.

In the above embodiment, the support bar 11, the spiral body 12, and the stirring means 13... May be a rod-shaped body or a narrow strip-shaped body. Increasing the width of the strip plate increases the stirring and grinding efficiency, but increases the resistance, causing a problem that the load increases. Further, the feed amount in the direction of the left and right drop openings 14 is determined by the width d (FIG. 2) of the spiral body 12. It is also possible to provide scrapers for preventing the fertilizer from adhering to the inner surfaces of the left and right side walls 16, 17 at both ends of the horizontal shafts 1 to 3. You may provide the scraper which prevents that a fertilizer adheres to the tank bottom wall 8 inner surface.

In FIG. 1, the mounting ears 22 and 22 provided on the horizontal support frame 21 and the mounting shafts 24 and 24 protruding horizontally from the vertical frame 23 are attached to the tractor link. Can raise and lower the entire fertilizer application. Therefore, when not in use, the leg frame 25 extending from the lower end of the vertical frame 23 to the bottom of the stirring tank h is left standing on the ground, and the fertilizer such as compost is put into the stirring tank h during use. In this state, the drive shaft 7 is rotationally driven by the output shaft of the tractor. It is also possible to attach and operate with wheels, pushing or towing, or in front of the cultivator. In addition to driving the drive shaft 7 with the output shaft of the tractor, it is possible to drive with a drive source such as a hydraulic motor.

As described above, since the spiral body is attached and supported via the support bar attached in the radial direction to the horizontal axis in the stirring tank, when the spiral body rotates to send out the fertilizer, The fertilizer is always stirred and pulverized by the support bar and spiral body, and the fertilizer can move relatively easily between the support bar and spiral body, so there is a risk that the load will increase and it will become impossible to drive In addition, a large amount of fertilizer can be processed.

It is a perspective view which shows the whole content of the fertilizer application by this invention. It is a longitudinal cross-sectional view of FIG. 1A-A direction of a stirring tank. It is a perspective view inside a stirring tank. It is a longitudinal cross-sectional view of FIG. 1B-B direction of a stirring tank.
