Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a deep plowing fertilization device that simultaneously performs deep plowing and fertilization of fruit trees, tea plantations, and other plants.

[Conventional technology]

Conventionally, when applying fertilizer to fruit trees, for example, the methods used were to spread the fertilizer around the roots of the fruit tree, or to spread the fertilizer by plowing deeply around the roots, then turning the soil over and applying the fertilizer into the ground. It was.

[Problem that the invention seeks to solve]

However, when fertilizer is applied around the roots, it takes a long time for the fertilizer components to penetrate into the ground and become effective, and there is also a risk that the fertilizer will be dissipated by rainwater.

Another problem was that the roots of fruit trees grew upward toward the fertilizer on the ground, which hindered their ability to establish firm roots. In addition, K requires a considerable amount of time and effort to dig around the roots and spread the fertilizer into the ground, and the roots break, making it impossible to apply fertilizer by deep plowing during the growing season (summer). The present invention has been made to solve the above-mentioned problems. When applying fertilizer to trees in orchards, etc., the present invention is an extremely simple and effective underground dispersion device for deep cultivation of fertilizer at the required time throughout the year. The purpose is to provide.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides a tank having a gas intake port communicating with a high-pressure gas source, and a gas injection port communicating with the outside of the tank, as a gas ejection mechanism that converts compressed gas accumulated in the tank into a gust of wind. a cylinder attached to the cylinder and having a spout on its side; a lid body equipped with an escape port attached to the end of the nuclear cylinder and having a means that can be opened and closed to the outside air; and supplying gas to the lid side. a gas ejection mechanism comprising: a piston that is equipped with a small vent hole for the purpose of operation, and that can slide within the cylinder to open and close the ejection port; and a means for urging the piston to close the ejection port; The other end of the pipe, one end of which is locked to the spout of the gas spouting mechanism, is driven into the ground, and a fertilizer insertion pipe is branched into communication with the upper end of the pipe, and an iK fertilizer spouting hole is provided at the lower end of the pipe. It consists of a pipe for distributing fertilizer.

[For production]

Therefore, as shown in Figure 1, 1 fertilizer dispersion pipe B
After driving the tip 12 of the tank into the ground and inserting fertilizer into the pipe 11 through the fertilizer insertion port 14, the gas blowing mechanism is started, and the high pressure gas accumulated in the tank 1 becomes a gust of wind. The fertilizer is ejected into the ground together with the fertilizer from the ejection hole 13 provided at the tip 12 of the fertilizer dispersion pipe B through the ejection port 3a, thereby achieving the desired fertilization effect.

〔Example〕

Next, embodiments according to the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram of an embodiment of the present invention. FIG. 2 is a cross-sectional view showing the gas ejection mechanism according to this embodiment, and FIG. 3 is a cross-sectional view of the main part when a gust of air is ejected.

Reference numeral 1 denotes a tank for storing compressed gas. In the tank 1, seven flange f51A are formed at the left end in the drawing, and a gas intake port 1a is formed through the right end. Note that the gas intake port 1a is communicated with a compressor C via a check valve 2.

3 is a cylindrical cylinder, and the right end of the cylinder 3 in the drawing is removably attached to and communicates with the 7th rank IAIC of the tank 1;
A lid 4 having an escape port 4a for back pressure gas is detachably attached to the left end, and three ejection pipes each having an ejection port 3a protrude from the side surface of the right end.

Note that the escape port 4a is communicated with the outside air via an on-off valve 5 such as a solenoid valve.

Reference numeral 6 designates a cylindrical piston, which has a communication hole 6a at its right end in the drawing, a small-diameter ventilation hole 6b at its left end, and annular seal members 7 at both left and right ends. 7, and is tightly fitted into the cylinder 3 so as to be slidable left and right.

Reference numeral 8 denotes a spring, and the spring 8 is installed in the cylinder chamber R formed between the lid 4 attached to the left end of the cylinder 30 in the drawing and the piston 6 fitted and pressed into the cylinder 3. Normally, the piston 6 is pushed to the right,
The spout 3a is blocked.

Reference numeral 11 denotes a pipe for spreading fertilizer, and the upper end 11 of the pipe 11
A is locked at the spout aa<. Further, a fertilizer insertion pipe 16 is protruded from the upper end of the pipe 11 and has a fertilizer insertion opening 14 . 15 is a reverse valve. 1 more
The lower end of the pipe 11 is driven into the ground to form a tip 12.
A fertilizer spout hole 13 is provided for dispersing fertilizer into the ground, and the tip thereof is formed into a pointed shape.

・Next, the operation will be explained. First, the tip 12 of the fertilizer dispersion pipe 11 is driven into the ground to be fertilized to an appropriate depth, then granular or powdered fertilizer is inserted through the fertilizer insertion port 14, and the check valve 15 is closed.

Then, when the compressor C is operated after closing the on-off valve 5 of the gas ejection mechanism, the gas gradually sent from the compressor passes through the check valve 2 and flows from the gas intake port 1a to the tank 1.
The air pressure inside the tank 1 gradually increases. Further, since gas also flows into the cylinder chamber R through the vent hole 6b of the piston 6, the air pressure rises almost simultaneously as the air pressure inside the tank 1 rises.

Note that as the atmospheric pressure inside the tank 1 and the cylinder 3 increases, the pressure difference between this atmospheric pressure and the atmospheric pressure on the jet port 3a side increases, so the outer circumference of the sealing member 7.7 is pressed against the inner wall of the cylinder 3. Leakage of the compressed gas in the tank 1 and cylinder 3 is prevented.

When the on-off valve 5 is opened after the pressure in the tank 1 has risen to a predetermined pressure, the back pressure gas in the cylinder chamber R is released to the outside air through the escape port 4a, and the pressure in the cylinder chamber R is instantly reduced to atmospheric pressure. As a result, a significant difference in air pressure occurs between the inside of the tank 1 and the inside of the cylinder chamber R, so the piston 6 is pushed by the compressed gas inside the tank 1 and rapidly slides to the left in the drawing while compressing the spring 8. The tank 1 and the spout 3a are brought into communication, and the compressed gas accumulated in the tank 1 is instantly discharged as a gust of air from the spout 3a.

FIG. 3 shows a cross-sectional view of the cylinder portion during gust discharge.

The gust of wind discharged from the spout 3a is blown out from a hole 13 appropriately provided at the tip 12 of the fertilizer dispersion pipe 11 driven into the ground. At this time, the fertilizer previously inserted into the pipe 11 is simultaneously blown away and spread into the ground.

Next, as the gas is discharged, the pressure in the tank 1 approaches atmospheric pressure, and the force that presses the piston 6 to the left in the drawing becomes smaller than the restoring force of the spring 8, and the piston 6 is pushed by the spring 8 and slides to the right in the drawing. The preparation for the next operation is completed.

In the above description, the gas ejection mechanism ti:r pumpresa C
Although the gas was compressed into the tank 1 using a compressor, a commercially available high-pressure gas cylinder may be used instead.

In this case, tank 1 and compressor C are omitted. Furthermore, it goes without saying that the present invention is not limited to the gas ejection mechanism of this embodiment, and that any mechanism that converts compressed gas into a gust of air can be used.

〔Effect of the invention〕

As described above, the present invention uses the pressure difference between the high-pressure tank and the cylinder chamber to cause the piston to slide and instantaneously communicate the tank and the spout. It can be changed into a gust of wind,
Fertilizer can be easily spread into the ground from the tip of a pipe driven into a desired location. Therefore, deep plowing and fertilization can be done at the same time, and there is no need to worry about root breakage. For this reason, deep plowing and fertilization work can be carried out throughout the year, and labor is greatly reduced. Furthermore, when air is used as the compressed gas, oxygen is ejected into the ground at the same time as the fertilizer is spread, which has a great effect on activating the soil.
