Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to underground air supply and fertilization equipment for orchards and the like.

When trying to get a tractor equipped with a tilling device into an orchard to till the topsoil, it is difficult to get into every nook and cranny because the branches are low and there are wires and other objects strung around the area. Also, even if you try to cultivate the topsoil deeply, it will only reach a depth of about 30 cm at most, and it will not be possible to cultivate it any deeper. Recently, an alternative method for tillage, in which compressed air is supplied by piercing a nozzle deep into the soil, has been adopted. This method is quite popular because it is easy to work with, and it can be expected to produce effects similar to those obtained by tilling the land.

According to the present invention, a fertilizer supply device is attached to the above-mentioned known air supply device so that fertilizer can be supplied at the same time as air supply, and the fertilizer can also be supplied easily and accurately.

In the present invention, a nozzle is inserted into the ground to supply air into the ground, and an outlet of a fertilizer supply path is opened in the air supply path to supply fertilizer into the ground together with air. In the fruit tree, a reservoir for measuring a repolva set is formed in the fertilizer supply path, and the fertilizer is supplied in a fixed amount to the air supply path through the metering reservoir. It is used as an underground air supply and fertilization device for gardens, etc.

To explain the embodiment, 1 is a left and right vertical slide frame formed of a channel frame with a U-shaped cross section, and a horizontal ground plate 2 is attached to the lower end of the frame. The upper ends of the vertical sliding frames 1, which are provided at regular intervals, are connected by an upper frame 3, and a vertical cylinder 4 is provided at the front side of the middle of the vertical sliding frames 1.1. The lower end of the cylinder 4 is fixed to the ground plate 2. A blowout air tank 5 is provided between the vertical slide frames 1 and 1.

Rollers are attached to both the left and right sides of the blowout air tank 5, and the rollers fit into the guide grooves of the left and right vertical slide frames 1.1, and the blowout air tank 5 is attached to the vertical slide frame 1.
move up and down as a rail. A driving part 6 is attached to the lower side of the blowout air tank 5. A nozzle 7 is provided at the lower part of the driving part 6. A projecting piece 8 having a horizontal portion is provided on the front surface of the blowout air tank 5.
The upper end of the piston 9 of the cylinder 4 is joined to the lower surface of the horizontal portion of the cylinder.

A supporting metal fitting lO that projects laterally is attached to the blowing air tank 5, and a fertilizer hopper 11 is fixed to the protruding part of the supporting metal fitting lO. Therefore, fertilizer hopper 1
The vibration of the driving part 6 is always transmitted to the drive unit 1 to stir the fertilizer, so that the fertilizer does not get clogged.

A guide vibrator 12 from the blowout air tank 5 is vertically provided on the side of the driving part 6, an opening 13 is formed at the lower end of the guide pipe 12, and a spherical valve 14 is provided on the upper surface of the opening 13. contact forcefully. A mixing chamber 15 is formed below the opening 13, and a vertical cylindrical inflow portion 16 is provided on the side of the mixing chamber 15. Mixing room 1! and the vertical cylindrical inflow part 16 are formed side by side, and the lower surfaces of both are cut horizontally, and the repolver complete metering storage part 17 is brought into contact with the lower side. The repolva complete metering and storage section 17 has a structure in which the upper surface is in close contact with the mixing chamber 15 and the lower surface of the vertical cylindrical inflow section 16 and rotates horizontally, and is rotatably mounted on a shaft 18 . The Repolva complete measurement storage part 17 is provided with about four pothole type measurement recesses 19.
When the repolva complete metering storage section 17 rotates, the mixing chamber 15
The pothole type measuring recess 19 matches the lower surface of the container. A latch 20 is attached to the lower surface of the repolva complete metering storage section 17, and an engaging body 21 is in contact with the latch 20. 22 is a guide tube.

At the top of the vertical slide frame l, there are screw holes 2 at predetermined intervals.
3, and the support metal lO is equipped with an ejection limit switch 2.
4 is provided, and its sensor 25 faces the engaging members 26 and 27 attached to the screw hole 23.

32 shown in Fig. 7 is a deep plowing adjustment plate, and the vertical rod 1
．． A slit 28 through which a threaded rod 29 protruding from 1 is inserted.
and is fixed with a washer 30. Reference numeral 31 denotes an air valve that is activated when the blowout air tank 5 and the driving part 6 move up and down;
As the driving part 6 moves up and down, its operating part 33 collides with the deep plowing adjustment plate 32, which has come into contact with the vertical slide frame l, causing O.
The operating section 33 is configured to turn off.
Attach the wire 34 to the lever 35, and connect the wire 34 to the lever 35.
The air hammer can be operated independently of the deep plowing adjustment plate 32 by operating the lever 35. 36 is a compressor, and 37 is an air hammer.

Next, we will discuss the effect.

When the ground plate 2 is lowered until it touches the ground and the piston 9 of the cylinder 4 is lowered to separate the piston 9 and the protrusion 8, the actuating part 33 of the air valve 31 is activated by the deep plowing adjustment plate 32 attached to the vertical slide frame 1. When the air valve 31 is joined and pressed, the air valve 31 is activated, and the air valve 31 is activated by the air hammer 37 and compressor 36.
Air is sent from the blowout air tank 5 to the air hammer of the driving part 6 for driving, and the nozzle 7 is impulsively driven into the ground to reach a predetermined depth. Then,
The sensor 25 hits the engaging members 26 and 27 to turn the ejection limit switch 24 ON and OFF, energizes the electromagnetic valve to raise the guide pipe 12, and raises the spherical valve 14, which is fixed to the lower end of the guide vibrator 12. Move the opening 13
to open. Then, the air ejected from the opening 13 passes through the mixing chamber 15 and is blown into the pot-hole type measuring recess 19, blowing the fertilizer in the pot-hole type measuring recess 19 into the mixing chamber 15, and sinking it into the ground together with the air. gushes out. By repeating this operation, the repolver set metering storage section 17 is transferred to the engaging body 2.
1 rotates it by 1/4, so the next deep fertilization can be done.

Since the blowout air tank 5 vibrates the fertilizer hopper 11 during the work, fertilizer clogging does not occur.

However, when the nozzle 7 is driven deep into the soil, the operating part 33
However, the deep plowing adjustment plate 32 will disengage and the driving will automatically stop.

In the embodiment shown in FIG. 7, the actuating portion 33 is pulled through the wire 34 by operating the lever 35, thereby allowing the nozzle 7 to be continuously driven mechanically. In the embodiment shown in FIG. 8, by turning on the switch 40, the limit switch 38 is turned on, the solenoid 39 is actuated, and the solenoid 39 continues to actuate the air valve 31 to drive the nozzle 7. A nozzle 7 is inserted into the ground to supply air into the ground, and an outlet of a fertilizer supply path is opened in the air supply path to supply fertilizer into the ground along with the air. In the orchard, a repolva complete metering storage section 17 is formed in the fertilizer supply path, and a fixed amount of fertilizer is supplied into the air supply path via the metering storage section 17. Since we have installed an underground air supply and fertilizer application device such as the above, it is possible to automatically measure and supply fertilizer.

The mouth and measuring mechanism are simple.

C. It is also easy to take out the fertilizer from the storage section.

This effect is achieved.
