Description

[Detailed description of the invention] This invention is a fertilizer supply device, especially when applying fertilizer in a fertilizer tank to cultivated land, making it extremely easy to adjust the appropriate amount and temporarily suspend and restart fertilizer application. Regarding fertilization equipment.

Conventional fertilizer application equipment has a fertilizer tank mounted on a trolley, and the fertilizer drop opening at the bottom of the tank is opened and closed using a lever, etc. to drop and temporarily suspend fertilizer use, which not only makes the work extremely complicated, but also makes it difficult to drop and administer fertilizer. There were times when things did not go smoothly. Furthermore, the amount of fertilizer thrown was determined by the size of the droplet and could not be adjusted.

The object of the present invention is to provide a fertilization device that allows easy start and stop of fertilization, allows for efficient use of fertilizer when the fertilization is interrupted, and allows easy adjustment of the amount of fertilization.

Another object of the invention is to
To provide a fertilization device capable of simultaneously fertilizing a row or multiple rows, thereby reliably applying fertilizer to both sides of a row where seeds fall.

Still another object of the present invention is to provide a fertilization device that can be mounted on an agricultural machine equipped with a ridge-cutting claw or the like and can stably and effectively fertilize multiple ridges at the same time while following the uneven ground of cultivated land. It's there.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a side view of a fertilization device according to an embodiment of the present invention, and FIG. 2 is a partial vertical sectional view of the fertilization device shown in FIG. 1. In addition, in FIG. 1, the fertilizer impeller is divided at the center and one side is removed for structural explanation. In FIG. 2, the fertilizer outflow control section and the fertilizer delivery section on one side of the machine frame are omitted from illustration. This fertilization device consists of a fertilizer tank 2 at the top of the device and a fertilizer tank 2.
Fertilizer outflow control section 1 installed below the
and a fertilizer delivery section 3 attached to the outer surface of the fertilizer outflow control section 1. Note that, as will be described later, this fertilization device can be mounted on a tiller, a ridge cutting machine, or the like that is pulled by a tractor or the like, and can be implemented as a ridge cutting fertilization machine or a fertilization seeding machine.

The fertilizer outflow control unit 1 of this embodiment has a box-shaped frame as a whole consisting of front and rear plates, left and right side plates, and a bottom plate, and the upper part of the frame is connected to the lower opening of the fertilizer tank 2. A substantially V-shaped connecting plate 15 is formed. As best shown in FIG. 2, a drive shaft 21, which will be described later, passes through approximately the center of the left and right side plates of the machine frame. Figure 3 is a front view of this machine frame. One machine frame side plate 1
6, a fixed outflow hole 4 is formed in the side plate 16 at a position connected to the V-shape of the connecting plate 15. FIG. 4 is a front view of the regulating plate 18 of the fertilizer outflow regulating section 1. The drive shaft 21 is located approximately at the center of the adjustment plate 18.
A hole 18a into which the adjustment plate 1 is loosely fitted is bored, and the adjustment plate 1
An arc-shaped long groove 18b concentric with the center hole 18a is formed in the upper part of the fixed outflow hole 4.
A regulating outflow hole 14 is bored so that it overlaps with the drain hole 14. As shown in FIG. 5, the adjustment plate 18 is held in close contact with the side plate 16 of the machine frame by passing the drive shaft 21 through its center hole 18a, and is stopped at the long groove 18b and the screw hole 16a of the side plate 16. It is fixed to the side plate 16 with screws 19.

Next, the fertilizer delivery section 3 will be explained. An arc-shaped impeller guide plate 17 that surrounds the adjustment plate 18 is attached to the machine frame side plate 16 so as to be concentric with the drive shaft 21 . The guide plate 17 is the third
Its upper and lower parts are partially removed as clearly shown in the figure. As will be described later, this lower portion will become the fertilizer drop opening 10. FIG. 6 shows the rotary impeller 12 from the back side, that is, in the direction of arrow F in FIG.
It is a figure seen from the direction. This rotary impeller 12 is
A plurality of sending blades 20 are attached radially around the back surface of an end plate 24 that is approximately equal to or slightly larger than the outer diameter of the impeller guide plate 17, and each inner end ( A cylindrical body 22 having the same height as the height of the sending blades is attached to connect the two ends (center side end). The rotary impeller 12 is housed within the impeller guide plate 17 so that the feed blades 20 are in contact with the machine frame side plate 16, and is fixed to the drive shaft 21 at the end plate 24. The drive shaft 21 is rotated by a drive source (not shown) via a transmission gear 23 at the end of the shaft.

In such a configuration, the fertilizer 25 in the fertilizer tank 2 is transferred from the V-shaped connecting plate 15 at the top of the machine frame to the side plate 1.
The liquid flows through the overlapping portion 26 of the fixed outflow hole 4 of No. 6 and the adjustment outflow hole 14 of the adjustment plate 18 and flows out between the sending blades 20 . Due to the rotation of the rotary impeller 12, the fertilizer flowing out from the outflow holes 4 and 14 is sent downward while being held between the adjacent sending blades 20, and reaches the position of the fertilizer drop opening 10 as shown in FIG. It falls from the tip of the feed blade 20. When temporarily suspending fertilization, the rotation of the rotary impeller 12 is stopped, and the fertilizer inside the impeller is transferred to each feed blade, guide plate 17, adjustment plate 18 (or machine frame side plate 16), and the end of the impeller. It remains stationary while being held between the plate 24 and the cylindrical body 22, and does not flow out from the drop port 10.
To adjust the amount of fertilizer applied, loosen the setscrew 19 of the adjustment plate 18 and rotate the adjustment plate 18 as shown in FIG. 5 to change the area of the overlap between the fixed outflow hole 4 and the adjustment outflow hole 14. Bye. Of course, if the rotational speed of the impeller is constant, the amount of fertilizer applied will be maximum when both outflow holes 4 and 14 are completely aligned.

FIG. 8 is an overall vertical sectional view of a fertilizer application device showing an embodiment of the present invention. In this embodiment, fixed outflow holes 4,
4' is formed, and correspondingly, the aforementioned adjustment plates 18, 18' and fertilizer delivery portions 3, 3' are provided on the left and right side plates 16, 16' of the machine frame. The fertilizer in the fertilizer tank 2 above the machine frame is transferred from the V-shaped connecting plate 15 of the machine frame to the fixed outflow holes 4 and 4' on both sides of the machine frame and the adjustment outflow hole 1.
It flows out to both sides of the machine frame through 8 and 18', and can be applied simultaneously through a pair of drop ports 10 and 10'. In this case, the interval between the falling positions is regulated by the interval between the left and right side plates 16, 16' of the machine frame. Therefore, when this fertilizing device is mounted on, for example, a seeding machine, the position directly below the machine frame is used as the seed position. Fertilizer can be applied accurately and in an appropriate amount to the left and right sides, and the seeds are not covered with fertilizer, thereby preventing the harmful effects of fertilizer burning. One fertilizer application device can apply fertilizer to two rows of a predetermined width from one fertilizer tank, but when fertilization on one side is not required, fertilization on one side can be easily stopped by operating one of the adjustment plates. The amount of fertilizer applied to the left and right sides can also be adjusted separately and independently.

FIGS. 9a and 9b and 10a and 10b respectively show an example in which the present invention is implemented as a four-row fertilization machine pulled by a tractor. In the example shown in FIGS. 9a and 9b, four carts 33 equipped with ridge cutting claws 32 are connected to a tractor 30 via a three-point link 31, and a fertilization device 34 is mounted on each cart. A spring 35 connects the connecting frame 37 of the three-point link 31 and the fertilizer application device 34. A transmission chain 36 is provided between the drive shaft 21 of the fertilizer application device 34 and the axle of the truck 33.
is attached, and automatic fertilization is performed as the trolley 33 travels. The cart 33 is provided corresponding to each ridge position. In this embodiment, the required number of furrows can be easily connected, and since the automatic height and lowering operations are performed independently for each furrow, it is possible to effectively follow uneven cultivated land and perform stable fertilization work. Figure 10a,
b is an example in which four fertilizing devices 34 are connected to a tractor (not shown) via a connecting frame 37 between a pair of wheels 37, 38 of a ridge cutter. The drive shaft 21 of the fertilizer application device 34 is connected to a chain 36 by one axle 39.
Driven through. In this embodiment, simultaneous fertilization of multiple rows can be carried out at low cost and efficiently. In addition, the fertilization device at the end in FIGS. 9b and 10b has the fertilization tank removed.

FIG. 11 is a diagram showing another embodiment of the adjustment plate of the fertilizer outflow control section described above. As is clear from a comparison with the embodiment shown in FIG. 4, in this embodiment, a plurality of fixing round holes 40 are provided in the upper part of the adjustment plate 18 concentrically with the hole 18a of the adjustment plate. The adjustment plate is fixed to the side plate of the machine frame by the aforementioned set screw passed through the hole. By changing the position of the hole through which the set screw passes, the position of the outflow hole 14 of the adjustment plate 18 is changed with respect to the fixed outflow hole of the machine frame. In this embodiment, when a plurality of fertilization devices are connected and used simultaneously as described above, the amount of fertilizer applied by each fertilization device can be adjusted more reliably than when a scale plate is attached to the arcuate long groove. and can be adjusted quickly. Furthermore, since the adjustment plate is fixed by passing a set screw through a round hole, there is no need to worry about the adjustment plate shifting along the long groove after it is fixed, unlike in the case of a long groove.

As mentioned above, according to the present invention, fertilization can be started and stopped easily and immediately by rotating and stopping the impeller drive shaft, and unlike conventional methods, the drop port can be opened and closed each time using a lever or the like. There is no need to do this, and the work can be done more efficiently and safely. Further, the amount of fertilizer applied can be easily and reliably adjusted by adjusting the position of the adjustment plate.
