Description

[Detailed description of the invention] [Industrial application field]

The present invention allows a pipe having a fumarole at the tip to be driven into the soil, and in this state, compressed air is ejected from the fumarole to easily cultivate the soil deeply. This relates to a pneumatic soil conditioner that supplies oxygen and promotes plant activation.

[Conventional technology]

As such a pneumatic soil improvement machine, the present applicant has developed an engine, a compressor driven by the engine, and
An air tank that stores air pressurized by the compressor, a pipe that is connected to the air tank via an operating valve, hangs down from the bottom of the air tank, and has a blowhole at its tip, and a pipe that uses the engine as a power source. A soil improvement machine main body is composed of an automatic driving mechanism that drives the rod into the soil, and a frame body that supports the main body so that it can be raised and lowered, and an engine that drives the soil improvement machine body to the frame body. The proposed system is equipped with an automatic pulling mechanism that pulls out pipes that have been driven into the soil while raising the soil as a source, making it possible to easily and efficiently perform the work of driving and pulling out pipes with little effort. . In this pneumatic soil improvement machine, as mentioned above, the same engine drives the compressor and automatic extraction mechanism, and the operation valve is opened after the pipe is driven into the soil to a predetermined depth. At the same time as the compressed air in the air tank is ejected from the nozzle, an automatic extraction mechanism is activated to pull the pipe out of the soil. Another method has been proposed in which a pipe is embedded in the soil to a predetermined depth, and after blowing out compressed air, fertilizer (liquid fertilizer) is supplied through the pipe for deep fertilization.

[Technical problem of the invention]

However, the soil in a field where trees and crops are planted has different working conditions, such as hardness and softness, so the operation valve is opened with the pipe driven into the soil, and the compressed air stored in the air tank is released. Even if the soil is ejected from the fumarole into the soil, if the soil is hard, cracks may occur in a narrow area and may not be plowed deeply enough. In addition, when compressed air is ejected into the soil from a fumarole and then fertilizer is supplied through a pipe, the fertilizer concentrates in the area around the fumarole and is not dispersed, resulting in less absorption through the roots of trees and crops. It will not be done enough. For these reasons, if fertilizer is supplied through a pipe after compressed air is injected from the fumarole or after the compressed air is injected, the operation valve should be closed after the injection is completed and the fertilizer should be removed from the air tank without immediately pulling out the pipe. Technology is required to accumulate compressed air inside the plant, open the operating valve again when the predetermined pressure is reached, and inject the compressed air again from the blowhole to expand the deep plowing area or spread fertilizer over a wide area. has been done. (Objective of the Invention 1) The present invention was conceived in view of the above circumstances, and has the function of operating an automatic extraction mechanism almost simultaneously with the ejection of compressed air from the jet nozzle, as in the conventional case, as well as the ability to remove the pipe as necessary. To provide a pneumatic soil conditioner which can carry out fumarole work twice or more times in the same place while still being driven into the soil, and which can expand the range of deep plowing.

[Structure of the invention] For this purpose, the present invention provides the soil improvement machine body with an automatic control mechanism that detects the air pressure in the air tank and automatically adjusts the engine to an idling state when the air pressure reaches a predetermined pressure. In addition to providing an opening/closing means for opening and closing the valve and an operating means for operating the automatic extraction mechanism, the automatic extraction mechanism and the automatic control mechanism are interlocked and connected, and the engine is operated at high speed at least while the automatic extraction mechanism is operating. The device is characterized in that the opening/closing means and the operating means, which are maintained in rotation and can be operated individually, are constructed so as to be operable at the same time. 【Example】

Next, the operation of the pneumatic soil conditioner of this embodiment will be explained. First, with the soil conditioner main body A held in a raised position relative to the frame main body B, the frame main body B is tilted, the single wheel 46 is brought into contact with the ground, and the pneumatic type Pushing the soil conditioner. Here, the grounding frame 42 is grounded and the frame body B is placed in the first position.
Stand it upright on the soil as shown. In this state, the mold receiving part 485 of the G-j folding tool 485 installed in the fall prevention mechanism 48
a supports the upper roller 243 (see Fig. 11), and the lower end of the nozzle 14 of the outer pipe 12 is located slightly above the lower end of the grounding frame 42, and the soil improvement machine main body A is held by the frame main body B and falls. do not. In addition, the winding bobbin 57
The hanging tools 67 are wound up in a spiral manner, and the clutch 59 is held in a clutch disengaged state in which the clutch pawls 570 and 590 are disengaged. In this state, hold the grip 487 of the lever 482 and rotate the lever 482 against the spring 488, so that the mold receiving part 485 of the folding tool 485
When the support of the rollers 243 by a is released, the soil conditioner main body A slightly descends with respect to the frame body B due to its own weight, the lower end of the nozzle 14 touches the ground, and the weight of the soil conditioner main body A is transferred to the outer pipe 12. By acting,
The automatic driving mechanism Aa operates for sliding movement with the inner pipe 10, and the receiver 120 provided at the upper end of the outer pipe 12
comes into contact with the cam 20a, and the entire weight of the soil improving machine main body A is applied to the receiving body 120 of the outer pipe 12 via the cam 20a. At the same time, since the cam 20a is eccentric by Δ1, the receiving body 12 is pushed by the pressing force due to the rotation of the cam 20a.
0 is struck, and the outer pipe 12 is efficiently driven into the soil while the soil improving machine main body A descends. Note that during this driving operation, since the clutch 59 is in the disconnected state, the driving force is not transmitted from the output shaft 56 to the winding bobbin 57, and the lifting tool 65 is almost completely removed from the winding bobbin 57. The number of soil Q while being fed out without resistance
The machine body A is lowered relative to the frame body B. In this way, the outer pipe 12 is connected to the soil improvement machine main body A.
After the pedal is driven in to the required depth to reach the lowering limit of
When 18 is pressed, the valve body 911 opens, and the high pressure air in the air tank 1 is transferred to the nozzle 1 provided at the tip of the outer pipe 12.
It is ejected into the soil from the fumarole 14a of No. 4. This fumarole causes cracks in the soil around the fumarole port 14a and the soil is plowed deeply, but if the soil is hard and it is desirable to expand the crack area by emitting fumes again, the compressed air in the air tank 1 can be left in that state. It is sufficient to press the pedal 918 again after the predetermined pressure is reached. Also, after blowing once, open the cock 701 and transfer the liquid fertilizer in the fertilizer tank 70 to the fertilization pipe 702. A predetermined amount of inner pipe 10 via injection lower 03
and injected into the deeply cultivated soil from the fumarole 14a,
Then, by emitting steam again, the fertilizer is dispersed into the deeply cultivated soil. When the pedals 252 and 918 are pressed simultaneously with the foot f as shown in FIG. 7 during re-injection, the actuating tool 624 rotates together via the linking tool 622 due to the rotation of the arm 250 at approximately the same time as the ejection. , the dock clutch 59 moves toward the take-up bobbin 57 against the spring 60, and the clutch pawls 510 and 590 engage. Therefore, the driving force of the engine 3 is transmitted from the output shaft 56 to the take-up bobbin 57 via the dock clutch 59, the lifting tool 67 is wound onto the take-up bobbin 57, and the soil improvement machine main body A is attached to the frame main body B. begins to rise against the As the soil conditioner body A rises,
A receiving body 120 is supported by the stroke tube 11 via the buffer body 13, and the outer pipe 12 driven into the soil is pulled out. At this time, the engagement between the clutch pawls 570 and 590 of the winding bobbin 57 and the dock clutch 59 is achieved by the engagement surface 570a.
. 590a is formed in an advance angle shape and an advance angle shape: Since a lifting force is applied to the winding bobbin 57 and a driving force is applied to the dock clutch 59, the biasing force of the spring 60 will not release the winding inadvertently. It never happens. Since the rollers 243 of the soil improvement machine main body A are guided by the guide rails 38, the posture when ascending is restricted, and the outer pipe 12 is pulled out vertically. In addition, as the hanging tool 67 is wound up on the winding bobbin 57, its diameter gradually increases, so the soil conditioner main body A is slow at the beginning of the rise, and gradually becomes faster as it rises (rises for a short time). In addition, since the lifting speed at the initial stage of pulling out, which requires the greatest force to pull out the outer pipe 12, is slow, there is less burden on the engine 3 and the drive power transmission system.Furthermore, while pulling out the outer pipe 12, Interlocking arm 627. Connecting rod 63° Since the Cheno 35 is pulled through the L-shaped tool 64, the O-rad 311 of the carburetor 300 is pulled up and the engine 3 is rotating at high speed, causing the automatic extraction mechanism C to operate. During the process, the engine rotation becomes idle-linked and does not stall. Then, when the outer pipe 12 is pulled out from the soil, the soil improvement machine main body A rises above the grounding frame 42, and the upper roller 243 is the oblique side 485 of the valuables 485 from below.
b against the spring 488 to pull the valuables 485 out of the guide rail 38 and reach above it. When the soil conditioner main body A rises to its upper limit, the collision between the abutment plate 52 and the engagement arm 624C causes the dock clutch 68 to be moved in the direction away from the take-up bobbin 57 via the shifter 624a, and the clutch pawl 570 and Disengage from 590,
Clutch 59 is placed in the disconnected state. As a result, driving force is no longer transmitted from the engine 3 to the winding bobbin 57,
The lifting operation is stopped. In this state, the receiving mold part 485a of the receiving mold tool 485 re-enters due to the restoring force of the spring 488, and the soil improvement machine main body A slightly descends to this position due to its own weight, but does not fall from here. Valuables 48
5, and the soil improvement machine main body A is held at the stop position. Then, the frame main body B is folded down and the pneumatic soil conditioner is carried out using the wheels 4G from the place where the air has been blown into the soil. Further, the compressed air in the air tank 1 becomes empty due to the jetting out from the jet nozzle 14a due to the opening operation of the valve body 911. Therefore, the sensing unloader 26 is activated, the operation unloader 29 is activated, and the rod 29a is activated. . The narrow rod 32 is pulled through the locking tool 34 of the metal fitting 31, the throttle rod 311 is pulled up, the engine 3 changes from the idle link state to high speed rotation, and the compressor 7 rotates at high speed. 36a is the valve plate 7
The air that is separated from the compressor 13 and compressed by the compressor 7 is sequentially stored in the air tank 1 through the pipe 8. At this time, Cheno 35 is slack. When the compressed air in the air tank 1 reaches a predetermined pressure, the sensing unloader 26 acts to push up the rod 29a of the operating unloader 29 as shown by the imaginary line in FIG. 12, and the throttle rod 311 descends, causing the engine 3 to idle. At the same time, the rod 36a of the operating unloader 36 pushes the valve plate 713 to compress the
Stop the compression operation of step 7. Note that if the soil in the field where the fumarole is to be applied is comparatively soft and the soil is sufficiently deep to be plowed with one fume, the pedals 252, 9
The objective is achieved by pressing down on 18 at the same time. When applying fertilizer at the same time, the cock 701 may be opened when the outer pipe 12 is driven to the required depth, and the fertilization may be sent to the blowhole 14a for subsequent blowing. Effects of the Invention 1 As explained above, according to the pneumatic soil conditioner of the present invention, it is possible to easily drive and handle the fumarole pipe with less power, and moreover, it is possible to easily drive the fumarole pipe and emit the fume once. After that,
We made it possible to emit fumes again in that state, so
Fumarole can be applied multiple times at the same location depending on the soil condition (hard or soft), achieving the desired deep plowing work and oxygen supply. Furthermore, since the air pressure in the air tank is detected and the engine is placed in an idling state when the air pressure reaches a predetermined value, the engine does not need to rotate at high speeds, and fuel efficiency can be improved. Furthermore, the pipe can be pulled out at the same time as the exhaust gas is drawn out while the engine is kept at high speed, and the work can be carried out efficiently without stalling during the drawing process. Furthermore, if the soil conditioner is equipped with a fertilizing device and once the soil is fertilized and then fertilized and aerated again, the fertilizer can be diffused into the deep layer and the fertilization effect can be enhanced.
