Description

[Detailed Description of the Invention] The present invention relates to a stirring device installed in a fertilization device attached to a mobile agricultural machine so as to stir the fertilizer put into the fertilizer tank of the device.

Although some of the above-mentioned fertilization devices were previously equipped with an agitation device inside the fertilizer tank, the agitation device communicates with the fertilizer dispensing mechanism, so two or more types of fertilization devices are used. When spraying a mixture of fertilizers, the fertilizer to be sprayed must be sufficiently stirred and mixed outside before being put into the fertilizer tank, making preparations for fertilization work troublesome. was there.

The present invention was developed to solve this problem, and allows for efficient mixing and agitation of two or more types of fertilizers to be sprayed within the tank by using the fertilizer tank of the fertilizer applicator. The purpose is to do so.

The fertilizer agitation device in the fertilizer application device attached to a tractor according to the present invention, which is a distant relative of this purpose, is formed in the shape of a horizontally long box, and the inner cavity of the fertilizer tank of the fertilizer application device is supported on the body of a mobile agricultural machine. A stirring blade for stirring and mixing the fertilizer put into the fertilizer tank is mounted so that it can be operated independently of the drive mechanism of the fertilizer dispensing mechanism provided in the fertilizer tank, and a stirring blade is installed below the stirring blade. The fertilizer tank is characterized in that a shutter is provided at the bottom of the fertilizer tank to prevent the fertilizer from falling into the fertilizer outlet.

Next, an example of implementation will be explained in detail according to the drawings.
In the figure, 1 is a conventionally known four-wheeled riding tractor;
is a conventionally known rotary tiller connected to the rear of the body 10 of the tractor 1, and its machine frame 20 is connected to the lift arm 1 that the tractor 1 has at the rear of the body 10.
It is designed to move up and down freely by the operation of 1, and
A tilling shaft 22 that rotates the tilling claws 21 of the device 2 is driven by a PTO shaft (not shown) provided on the rear surface of the body 10 of the tractor 1.

3 is a fertilizer application device, and a fertilizer tank 30 is the main part of the device.
is formed into a horizontally elongated box shape and supported on a mounting frame 31 provided on the machine frame 20 of the tilling device 2, and a slit-shaped fertilizer is provided at the bottom of the tank 30 facing in the left-right direction of the body 10 of the tractor 1. A transmission mechanism in which a feed-out port 32 is provided, a feed-out roll 33 whose axial direction is in the left-right direction is mounted on the fertilizer feed-out port 32, and its rotating shaft 34 is mounted on the outer surface of one side of the fertilizer tank 30. The input shaft 36 of the transmission mechanism is connected to the body 10 of the tractor 1 described above.
By driving the above-mentioned feed roll 33 by transmitting the power to the rotating shaft of a power take-off shaft provided as appropriate in the fertilizer tank or a power take-off shaft separately provided to freely rotate while grounded, the feed roll 33 is driven. The fertilizer put in the fertilizer tank 30 is fed out and spread, and the top surface of the fertilizer tank 30 is equipped with an opening/closing lid 38, and the feeding opening 32 is provided with a lid 38 facing the outer peripheral surface of the feeding roll 33. This is no different from the previous one in that the tip is provided with an adjusting brush 39 that can be freely adjusted forward and backward with respect to the circumferential surface of the roll 33.

However, the width of the fertilizer tank 30 that stores the fertilizer of the fertilizer application device 3 is narrow in the lower half, and widened in the front and back, as shown in FIGS. 2 and 3. The upper half a which is narrower in width serves as a substantial fertilizer tank, and the narrower lower half serves as a substantial fertilizer tank.
The lower half of the guide gutter is formed to serve as a guide gutter that guides the fertilizer inside toward the above-mentioned outlet 32, and at the upper end of the lower half of the guide gutter, there is a conductive channel in the conduction mechanism 35 described above. The roll 3 is moved in the same direction as the feed roll 33 as shown by arrow A in Figure 2.
A blade wheel-shaped shutter 4 that rotates at a slower speed than the shutter 3 is provided.

In the upper half a which is widened in the front and back, there is a rotating shaft 50 which is supported by the left and right plate walls 30a of the fertilizer tank 30 and rotates, as indicated by the chain line W in FIG. As shown in FIG.
The tank 30 of the rotating shaft 50 is installed.
A handle rod 52 that can be operated and rotated arbitrarily outside the fertilizer tank 30 is connected to the shaft ends protruding from the left and right plate walls 30a.
By rotating the agitating blades 51 in a desired forward or reverse direction by the operation 2, the agitating device can be used to agitate and mix the fertilizer put into the fertilizer tank 30 at any time.

Note that the stirring blades 51 are attached to the rotary shaft 50 in a staggered manner by bending the shaft rod into a triangular shape as shown in FIGS. 3 and 4, or as shown in FIG. 5. They may be formed into any suitable shape, such as when they are formed into a wing plate shape and attached in a staggered manner.

As explained above, the stirring device 5 in the fertilizer application device mounted on a tractor according to the present invention has a stirring blade 51 installed in the wide part of the inner cavity of the fertilizer tank 30 so that the inner cavity can stir the entire area. ... is installed, and the stirring blades 51 ... can be rotated at any time in a desired direction by operating a handle rod 52 provided on the outer surface of the fertilizer tank 30. For example, When spraying a mixture of lime nitrogen and dissolved phosphorus fertilizer, by putting these fertilizers into the fertilizer tank 30 and operating the handle rod 52, the fertilizer to be sprayed can be sufficiently agitated and mixed. That will happen.

This stirring and mixing is carried out by the rotating shaft 5 of the stirring blade 51...
0 can be driven completely separately from the operation of the feed roll 33 and shutter 4, so it can be performed with the feed roll 33 and shutter 4 stopped, so it is possible to apply fertilizer before spreading. Fertilizer tank 30 of device 3
can be used in the same way as a stirring tank for mixing and stirring fertilizers, which not only eliminates the need for a stirring tank, but also enables the spraying work to be carried out immediately after the stirring and mixing work is completed. This makes it easier to mix and spread two or more types of fertilizers, and also to simplify the work process.

Note that the device of the present invention can be used as is, not only as a fertilizing device mounted on a tractor, but also as a fertilizing device coupled and mounted on a harvester.
