Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention involves driving a pipe with a fumarole at its tip into the soil, and in that state compressed air is ejected from the fumarole to deeply cultivate the soil. The pneumatic method also supplies air, or oxygen, to the roots of plants such as trees and crops, promoting plant activation.
This is for an improved machine.

[Prior art 7] As such a pneumatic soil conditioner, the present applicant has developed an engine and a compressor driven by the engine, as shown in Japanese Patent Application Laid-Open No. 58-9HO3, for example. ,
an air tank that stores air pressurized by the compressor; a pipe that extends through the air tank and an operating valve and is vertically disposed 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 body is composed of an automatic driving mechanism that drives the soil improvement machine into the soil, and this body, a frame body that supports the body so that it can be raised and lowered, and an engine that connects the soil improvement machine body to the frame body as a power source. Equipped with an automatic pulling mechanism that pulls out the pipe that has been driven into the soil while raising the pipe, the work of driving and handling the pipe can be done easily.
We are proposing something that can be done easily and efficiently with little effort.

In this pneumatic soil improvement machine, as mentioned above, the same engine drives the compressor and the automatic extraction mechanism, and the engine is automatically activated when the air pressure in the air tank reaches a predetermined set pressure. An automatic control mechanism is also provided to keep the engine in an idling state, eliminating unnecessary high-speed rotation of the engine and improving fuel efficiency.

[Technical Problem of the Invention] However, the soil in fields where plants such as trees and crops are cultivated has different soil conditions, such as hardness and softness, and the length of time required to drive the pipe into the soil to a predetermined depth is difficult. is not constant. For this reason, the pipe can be driven smoothly while the compressor is feeding air into the air tank, that is, when the engine is rotating at high speed and the output is high and the automatic driving mechanism is operating. However, if the air pressure in the air tank reaches a certain level before or during pipe driving, the engine will idle and its output will drop, and the automatic driving mechanism will not work properly, which may cause This will cause the engine to stall.

[Object of the Invention] The present invention has been made in view of the above-mentioned circumstances, and during the pipe driving work, the engine is rotated at high speed to maintain a high output state, thereby preventing engine 1~ and automatic driving. To provide a pneumatic soil improving machine which allows efficient deep plowing work by sufficiently operating a driving mechanism to smoothly perform pipe driving work.

[Structure of the Invention] In order to achieve this object, the present invention includes an automatic control system in the soil improvement machine body 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. A mechanism is provided between the main body of the soil improving machine and the main body of the frame, and is activated by the descending movement when the main body of the soil improving machine descends along the main body of the frame while the pipe is driven into the soil by automatic driving n4t4.

It makes the mat theory easier.

Next, the operation of the pneumatic soil conditioner of this embodiment will be explained.

First, with the soil conditioner main body A held at the 1-up position relative to the frame main body B, the frame main body B is tilted, the single wheel 4G is grounded, and the handle 39 is held until the air is I push the soil conditioner. Here, the grounding frame 42 is grounded to the ground surface G (-), and the frame main body is placed upright on the soil as shown in FIG. The upper roller 243 is supported by the mold part 485a (first
1), the lower side 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 body Δ is held by the frame body B and does not descend. Further, the hanging tool 67 is stacked on the winding bobbin 57 in a cylindrical shape, and the clutch 59 is held in the clutch disengaged state in which the clutch pawls 570 and 590 are roughly disengaged, and the response tool 66 is in contact with the rising end side protrusion 7o. In this state, hold the grip 487 of the lever 482 and rotate the lever 482 against the spring 488, so that the receiving mold part 48 of the receiving shell 485
When the support of the rollers 243 by the rollers 5a is released, the soil improvement machine main body A slightly descends with respect to the frame main body B due to its own weight, the lower end of the nozzle 14 touches the ground, and the weight of the soil improvement machine main body A is transferred to the outer pipe 12. By acting, the automatic driving mechanism Aa for sliding movement with the inner pipe 10 is activated, and the receiving body 12 provided at the upper end of the outer pipe 12 is activated.
0 comes into contact with the cam 20a, and the entire weight of the soil improving machine main body A is applied to the mold rest 120 of the outer pipe 12 via the cam 20a. At the same time, since the cam 20a is eccentric (), the mold break 120 is struck by the pressure generated by the rotation of the cam 20a, and the soil improvement machine main body A descends while the outer pipe 12 is struck into the soil. be included.

When the soil conditioner main body △ starts to descend, the response g66, which had been in contact with the upper R end side protrusion 7o and held the check 235 in a loose state as shown in Fig. 9, moves to the rising end side protrusion. As a result of the contact with 70 being released, as shown in FIG. 235, and the I rod 22 is pulled, causing the throttle rod 311 to protrude and maintain the engine 3 at high speed and high output.Therefore, while the soil improvement machine main body A is descending, the automatic driving mechanism Aa is set to high. The outer pipe is efficiently driven into one bag of soil without being activated by the output.When the outer pipe 12 is driven to a predetermined depth and the soil improvement machine main body A reaches its lower end as shown in Fig. 15, the outer pipe is driven into the soil bag efficiently. As shown in FIG.
5 becomes loose, and the engine 3 is left with low output in an idling state.

Also, when the soil conditioner main body Δ descends, the air tank 1
When compressed air is being stored, the engine 3 is maintained at high speed and high output by the automatic control mechanism Ab, so even if the automatic response mechanism is activated, the engine 3 continues to rotate at high speed. Even if the compressed air in the air tank 1 has reached a predetermined pressure when the soil improvement body A starts to descend, and the engine 3 is maintained at low output in an idling state by the automatic control mechanism At+, automatic response is performed. Due to the mechanism, the engine 3 rotates at high speed and has high output.

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 5G to the winding boggon 57, and the lifting tool 65 is not transmitted from the winding bobbin 57. The soil conditioner main body A descends relative to the frame main body B while being unrolled with almost no resistance.

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 arm 915 rotates to open the valve body 911, and the high pressure air in the air tank 1 is ejected into the soil from the blowhole 14a of the nozzle 14 provided at the tip of the outer pipe 12. This fume creates cracks in the soil around the fumarole 14a and cultivates it deeply, and at the same time as this fume, the actuating tool 624 rotates together via the linking tool 622 due to the rotation of the arm 915, so it resists the spring 60. Then, the dock clutch 59 moves toward the take-up bobbin 57, and the clutch pawls 570 and 590 are engaged. 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 Δ increases,
The contact between the lower end protrusion 71 and the response tool 66 is released, the engine 3 rotates at high speed, and the receiver 120 is supported by the stroke tube 11 via the buffer 13 and driven into the soil. Outer pipe 12 is pulled out.

At this time, the engagement between the clutch pawls 570 and 590 of the take-up bod 57 and the dock clutch 59 is achieved by the engagement surface 570.
a, 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 be released inadvertently. Since the rollers 243 of the soil conditioner main body A are guided by the guide rails 38, the upper 4 o'clock position is restricted, and the outer pipe 12 is handled vertically. In addition, as the hanging tool 67 is wound onto the winding bobbin 57, its diameter gradually increases, so that the soil conditioner main body A is slow at the beginning of the rise, and gradually rises faster as it rises. Since the outer pipe 12 can be raised in a short time and the rising 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.

When the outer pipe 12 is removed from the soil, the soil improving machine body △ rises above the grounding frame 42, and the upper row 5243 is moved from below to the oblique side 485 of the catch 485.
b against the spring 488 to retract the catch 485 out of the guide rail 38 and reach above it. When the soil conditioner main body Δ rises to the upper R limit, the collision between the abutment plate 52 and the engagement arm 642G moves the dock clutch 68 in the direction away from the take-up bobbin 57 via the shifter 624a, and the clutch pawl 570 and 590,
The clutch 59 is brought into the disconnected state. As a result, the driving force is not transmitted from the engine 3 to the winding bobbin 57.
The lifting operation is stopped. In this state, the receiving part 485a of the receiving shell 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 descend from this point. Receptacle 48
5, and the soil improvement machine main body △ is held at the stop position. Further, the response tool 6G comes into contact with the epigastric end side protrusion 70, and the engine 3 becomes in an idling state.

Then, the frame main body B is folded down and the pneumatic soil conditioner is moved using the wheels 4G from the place where the air is blown into the soil to the next mulberry harvesting place.

Further, the compressed air in the air tank 1 is emptied by being ejected from the jet nozzle 14a due to the opening operation of the valve body 911, so that the sensing unloader 2G is activated and the operation unloader 29 is activated, and its 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 an idling state to high speed rotation, and the compressor 7 rotates at high speed. is 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. Air tank 1
When the compressed air inside reaches a predetermined pressure, the sensing unloader 2G
acts, and the rod 29a of the operation unloader 29 moves to the twelfth position.
Throttle rod 3 is pushed up as shown in the imaginary line in the figure.
11 is lowered and the engine 3 is in an idling state, the rod 3f3a of the operating unloader 36 is moved to the valve plate 71.
3 to stop the compression operation of the compressor 7.

In the above embodiment, after the pipe is driven into the soil to a predetermined depth, the operation valve is opened to blow the compressed air in the air tank into the soil from the blowhole, and the automatic extraction mechanism is activated almost at the same time to remove the pipe. The operation of the operating valve and the automatic extraction machine 414 are linked to pull out the fuel from the soil, and during high-speed rotation of the engine during the period from when the air tank is empty immediately after blowing up to when the pressure is accumulated to a predetermined set pressure. The pressure delivery capacity of the compressor is set so that the pipe removal is completed, but the pressure delivery capacity of the compressor is so large that the pressure inside the air tank accumulates at the predetermined set pressure J: before the pipe removal is completed. Even in such a case, due to the structure in which the automatic response device 414 and the automatic control mechanism of the present invention are interlocked and connected, the engine will continue to rotate at high speed from the descending end to the ascending end of the soil improvement machine body. , regardless of the capacity of the compressor, the engine is kept at high speed during pipe insertion and removal,
Both tasks can be done efficiently without stalling.

[Effect of the invention] As explained above, the air soil conditioner according to the present invention has the following effects:
The work of inserting and pulling out fumarole pipes can be easily done with less power, making it easier to install and remove fumarole pipes. The machine is equipped with an automatic control mechanism that detects the air pressure in the air tank and automatically sets the engine to idling when the air pressure reaches a predetermined set pressure, eliminating unnecessary high-speed rotation of the engine and reducing fuel consumption. can be improved.

In addition, an automatic response mechanism is provided at Nj+ between the soil improvement machine body and the frame body, which is activated by the downward movement of the soil improvement machine body with respect to the 71 mm body, and this automatic response I! lI
The structure and automatic control mechanism are interlocked and the engine is kept at high speed at least while the soil improvement machine is descending, so that it can be used in soil areas where trees, crops, and other plants are planted. The soil is hard and it takes a relatively long time for the automatic driving mechanism to drive the pipe into the soil to the specified depth, and even if the air in the air tank accumulates to the specified set pressure during driving, The engine does not go into the low-output state of idling, but maintains high-speed rotation and high-output state, making it possible to drive the pipe smoothly without stalling.Furthermore, before starting to drive the pipe, Even if the air pressure has accumulated up to a predetermined pressure and the engine is in an idling state, when the soil conditioner body begins its downward movement relative to the frame body, the engine is automatically maintained at a high speed rotation and high output state, and the pipe Driving can be done smoothly and effective deep plowing work can be carried out.
