Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of spreading fertilizer, etc. using an agricultural tractor.

Traditionally, when spreading fertilizers, etc., a separately purchased mixer was used to mix the mixture, and then the mixture was transferred to the spreader and spread.
In this case, it goes without saying that a separate mixer is required.
Since the equipment and time required to transfer fertilizer from a mixer to a spreader is very time consuming, the present invention has been developed to provide a method of spreading fertilizer that does not use the mixer, and is extremely easy to handle. Another object of the present invention is to make it easy to implement by using existing agricultural tractors.

According to the present invention, a mixing/fertilizer tank attached to the rear of a four-wheeled riding tractor is filled with several types of fertilizers, and a drop opening of the tank is closed by operating a clutch of the four-wheeled riding tractor to fill the tank with fertilizer. The gist is a method of spreading fertilizer, etc. using an agricultural tractor, in which mixing and spreading are carried out in a single tank by rotating a stirring rod inside the tank, and then opening the drop port to spread the fertilizer.

The side entrance relates to a device that can carry out the spraying method of the present invention, and to explain it with a diagram, l is a four-wheeled riding tractor having front wheels and rear wheels, and the rear upper part of the four-wheeled riding tractor 1 has a The front end of the top link 3 is fixed to the shaft 2. The top link 3 has both ends screwed together, the center formed into a turnbuckle with a spiral cylinder, and is expandable and retractable. At the bottom of the top link 3, the front ends of a pair of left and right lower links 6 are attached to an axis I.
J: 5. A three-point link is formed by the top link 3 and the lower link 6, and a side-shaped support 12 is pivoted 4.7 at the rear end. Reference numeral 8 denotes a lift arm 8 provided at the rear end of the four-wheeled passenger tractor l.The upper end of the lift rod 9 is fixed to the tip of the lift arm 8, and the lower end of the lift rod 9 is pivoted to an intermediate position between the front and rear of the lower link 6. Stop 10.

11 is a PTO shaft of a four-wheeled passenger tractor. A mixing/fertilizer tank 16 formed by a vertical cylinder is placed on the upper surface of the support base 12. The mixing/fertilizer tank 16 has a mouth-like shape in every longitudinal section, and has a horizontal bottom plate 27, at the center of which a vertical rotating shaft 18 is attached. Reference numeral 17 denotes a transmission, which is provided below the center of the horizontal bottom plate 27, and the lower end of the rotating shaft 18 is connected to the upper surface of the center of the transmission 17. A plurality of stirring rods 19 protrude from the rotating shaft 18 in the radial direction.

A connecting portion 13 is connected to the PTO shaft 11, and a transmission 17 is connected to the rotating shaft 14 via a universal joint 15.15.

At a position rearward from the center of the horizontal bottom plate 27, drop ports 20.20 are provided at two positions on the left and right, an on-off valve 28 is provided at the lower end of the drop port 20.20, and a horizontal rotating scattering plate 22 is provided below the drop port 20.20. . The opening and closing of the on-off valve 28 can be operated on the tractor l by remote control. The horizontal rotary scattering plate 22 is fixed to the upper end of the vertical rotating shaft 21, and several protrusions 23 each having a cross section shaped like this are attached radially to the upper end. Each scattering prevention plate 24 is provided on the outside, and its base 25 is attached to the outside of the mixing/fertilizer tank 16.

Next, the operation of the above embodiment will be described.

As described above, the configuration of the embodiment of the present invention is such that the front end of the top link 3 is fixed to the shaft 2 at the rear of the four-wheeled riding tractor 1, and the front end of the lower link 6 is fixed to the shaft 5 at the rear of the four-wheeled riding tractor 1. A support stand 12 is pivoted to the rear ends of the top link 3 and lower link 6, respectively, and the lower end of the lift rod 9, which is pivoted to the tip of the lift arm 8, is pivoted to the middle of the front and rear of the lower link 6. stop 10L, transmission 17 installed at the bottom of the mixing/fertilizer tank 16 attached to the support stand 12, and the PTO shaft 1 at the rear of the two-wheeled four-wheeled passenger tractor l.
1 is connected to the rotary shaft 14 via the universal joint 15.15, the preparation is completed.

Next, the drop port 20 remains closed by the on-off valve 28,
For example, put different types of fertilizer A, fertilizer B, and fertilizer C into the mixing/fertilizer tank 16 as shown in FIG. When the PTO shaft 11 is rotated by operating the
By transmitting the rotation to the transmission 17 through the transmission 17 and rotating the rotary shaft 18, the different types of fertilizer A, fertilizer B, and fertilizer C are mixed as shown in FIG. 7. Therefore, when the clutch of the PTO shaft 11 is disengaged from the driver's seat and the hydraulic lever of the tractor 1 is operated, the lift arm 8 rotates upward and the lower link 6 is flailed upward by the lift rod 9. The fertilizer tank 16 is easily raised and moved to a desired position in the field.

At a predetermined position in the field, the hydraulic system of the four-wheeled riding tractor 1 is operated to lower the lift rod 9 pivoted to the tip of the lift arm 8, and at the same time, the mixing/fertilizer tank 16 is lowered.

When the clutch is operated to rotate the PTO shaft 11, the rotation is transmitted to the transmission 17 via the coupling part 13, the universal joint 15, and the rotating shaft 14, rotating the rotating shaft 18 and the rotating shaft 21, 21, and rotating the stirring bar. 19 and the horizontal rotating scattering plate 22 are rotated.

Therefore, when the operating lever for remote control of the tractor 1 is operated to open the on-off valve 28, the mixed fertilizer in the mixing/fertilizer tank 16 is stirred by the stirring rod 19 and falls from the drop opening 20, and is scattered horizontally. It is supplied onto the plate 22.

Since the horizontal rotary scattering plate 22 is formed with a protrusion 23 having a cross section shaped like this, the fertilizer is carried around by the protrusion 23 having a shape and is scattered in the centrifugal direction to the field. It is dispersed.

Traditionally, when spreading fertilizers, etc., a separately purchased mixer was used to mix the mixture, and then the mixture was transferred to the spreader and spread.
In this case, it goes without saying that a separate mixer is required.
The device and time required to transfer fertilizer from a mixer to a spreader was difficult, but in the present invention, several types of fertilizers are filled into a mixing/fertilizer tank attached to the rear of a four-wheeled riding tractor, and the drop opening of the tank is By operating the clutch of the four-wheeled riding tractor with this closed, the stirring rod in the tank is rotated to mix the fertilizer, and then the drop port is opened to spread the fertilizer. Mixing and spreading are performed in one tank. Since it is configured to use an agricultural tractor to spread fertilizer, etc., for example, when you want to mix and spread nitrogen fertilizer, phosphoric acid fertilizer, and processed fertilizer, you can easily mix and spread it without having to purchase a separate mixer. sell.
