Description

TECHNICAL FIELD The present invention relates to a fumarolic soil conditioner, and more specifically,
The present invention relates to a fumarolic soil improvement machine in which a fuming working machine for performing fuming work is mounted on a frame mounted on a tractor or the like so as to be vertically movable.

[Conventional technology]

Soil softening in fields that have been continuously cropped, such as fields that have become harder under the influence of trampling pressure such as tractors, is very preferable from the viewpoint of increasing soil water permeability and water retention, and promoting the growth of crops. Also, supplying air into the soil is very significant in promoting the growth of bacteria.

Therefore, it has been proposed in the past that a large amount of compressed air is instantaneously and explosively supplied into the soil to swell and soften the soil, and at the same time, the air is supplied to grow bacteria.

As a specific prior art thereof, Japanese Patent Publication No. 63-10962 can be cited. The one shown here is equipped with a fume working device for ejecting compressed air into the soil through a three-point hitch mechanism to a tractor, and this fume working device is moved up and down via a lift arm of the tractor. The air-injection work apparatus is configured to lower the air-injection nozzle when a ground signal is obtained by the ground sensor and insert the air deep into the soil to eject compressed air into the soil.

[Problems to be Solved by the Invention]

The above-mentioned fumarolic soil conditioner performs intended work while moving the work equipment attached to the tractor by the tractor.However, during the fumarolic work, the work is temporarily stopped at the fumarolic position and the tractor is operated. The fumarolic working device is lowered to the grounded state, then the fumarolic nozzle is driven into the soil, the fumarolic work is performed by the fumarolic nozzle, and the fumarolic working device is lifted together with the fumarolic nozzle to move to the next fumarolic position. .

Therefore, when performing fumarolic work at a relatively short pitch in the field, the working device must be lowered and lifted together with the fumarolic nozzle for each fuming work, and the working device is lifted and lowered rather than the work of the fumarolic work itself. It is time consuming and wastes work time.

Further, since the timing of the moving work and the blow-off work are performed by a skilled work procedure of a worker such as a tractor, it is difficult for a beginner to work, and there is a problem that the device is damaged if the procedure is incorrect.

Therefore, an object of the present invention is to provide a fumarolic soil conditioner capable of performing efficient work by shortening the time required for lifting and lowering the fumarolic work device as much as possible.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention includes a mounting frame body that is vertically moved by a mobile agricultural machine, and a fusogenic work machine that can be moved up and down with respect to the mounting frame body, , At least a compressor, a pressure accumulator tank, and an air-jet nozzle provided with an ejection port at the tip, and detects a grounded state and a non-grounded state at the lower end of the mounting frame by the vertical movement of the mounting frame. A traveling body is provided, and the traveling body has a function of bringing the fuming working machine into a workable state when a grounded state is detected, and a predetermined rising position of the fuming working machine with respect to the mounting frame body when a non-grounded state is detected.

A pressure gauge 407 is attached to the circuit of the control system 403 to display the pressure in the system.

Next, the soil loosening work by the fumarolic soil conditioner according to the present invention, that is, the work of lifting and lowering only the fuming work machine 300 with respect to the mounting frame 200 to blow compressed air into the soil will be described.

First, to the mobile agricultural machine 100, the mounting frame body 200 equipped with the fuming working machine 300 is mounted by a three-point hitch including the upper link 101 and the lower link 102. In this state, the mounting frame body 200 can be moved up and down by the lift arm 103, maintain an appropriate height when moving on the road, and when mounting or escaping from the field and when entering the field. Hold the lifted state so that the robot does not come into contact with the ground.

Then, when performing a fumarolic work in the field, the mounting frame body 200 is lowered by driving the lift arm 103 until it comes into contact with the field ground, and the traveling body 211 provided at the lower end portion thereof is grounded. When the traveling body 211 is not in contact with the field ground, the traveling body 211 is pulled by the elastic force of the spring 212 via the arm 213 and is rotated about the pivot point 213B.
Since the arm 213 integrated with 211 is in contact with the stopper 213A, the grounding posture is changed from the state shown by the chain line in FIG. 5 to the posture shown by the solid line. When the traveling body 211 is grounded and rotated, the grounding sensor 222 is pressed, and the lowering start valve 415 is switched from the position 415X shown in FIG. 12 to another position 415Y against self-habit.

At this time, part of the power of the mobile agricultural machine 100 is partly driven by the fuming working machine 30 mounted on the mounting frame 200 from the PTO shaft 107 via the conductive shaft 108.
0 is transmitted to the input shaft 312, the pulleys 306 and 307 are rotated together, and the hammer unit 308 and the reduction shaft 311A of the hoisting machine 310 are driven by the driving force from the input pulleys 308A and 309 via the belts 306A and 307A. Is driven by. At this time, the belts 306A and 307A are given a tension suitable for torque transmission by the tension pulleys 306B and 307B.

The hoist 310 has a dog clutch due to the extension of the cylinder 314.
Drum 312 when 313 is engaged against drum 312
Is rotated and the wire 312A is wound up. As a result, the fuming working machine 300 rises and the rising end sensor 202 is moved to the surface cam 330.
When pushed by the cam projection 331, the position of the raising control system 411 of the control system is switched from 411X to 411Y.

The air supplied from the compressor 320 by this position switching is supplied from the accumulator tank 326 to the clutch switching valve 412 via the rising control valve 411, the position 412X is selected, the air cylinder 314 contracts, and the dog clutch 313.
Turns off and hoisting is stopped.

In this state, the one end portion 217A of the stopper 217 is rotated by the pulling force of the spring 218 and protrudes into the moving area of the locking roller 302Z, so that even if the dog clutch 313 does not restrain the drum 312. The rising state of the fuming working machine 300 is maintained. Also at this time, the ascending control valve 411 is driven by the ascending end sensor 202 to move from the positions 411X to 411X.
It has been switched to Y.

When the traveling body 211 is grounded, the descent start valve 415 has been switched to the position 415Y and thus is in a workable state. In this state, the work start button 413A in the operation unit 106 of the mobile agricultural machine 100. When is pressed, the position of the work start valve 413 is switched from 413X to 413Y, and compressed air is supplied to the air cylinder 219 from the Y position of the lowering start valve 415.

When the air cylinder 219 extends, the extension end 219A stops at the stopper 217.
When the end portion 217A is rotated to release the restraint of the locking roller 302Z, the squirting work machine 300 descends due to its own weight, descends until the squirting nozzle 328 of the driving pipe 327 comes into contact with the ground, and stops descending there.

At this time, since the pressing of the fixed position sensor 203 of the work mode display switching valve 405 is stopped, the work mode display switching valve 405 whose position 405Y is selected by the fixed position sensor 203 is
Position 4 by fusing work machine 300 descending from its home position
Since it is self-returning to 05Y, the air pressure (arrow C1) from the pressure regulator 404 is applied to the mode display button 406B via the work mode display switching valve 405, and this is in the protruding state, so that the fusing work machine 300 is moved from the fixed position. A visual indication that you have moved.

At this time, since the hammer shaft 308C of the hammer unit 308 is driven by the torque input to the input pulley 308A, the eccentric cam 308B is rotated, hits the hit part 329, and is output from the descending end sensor 216. Up to 327
Is driven.

When the driving pipe 327 is driven and the lowering control valve 451 is operated, the unloader 452 is switched from its position 452X to the position 452Y by the air pressure (arrow C1), and the air pressure C2 is already switched to the position 451Y. It is added to the control end 402A of the switching valve 402 via the descending control valve 451 that opens the squirt gas supply system 401 to instantaneously supply compressed air from the tip of the squirt nozzle 328 into the soil to soften the soil.

Almost at the same time, the position 451Y of the lowering control valve 451 is opened to supply compressed air in the direction of arrow C3,
The driving pressure is applied to the clutch switching valve 412 from the shuttle valve 453, the air cylinder 314 of the dog clutch 313 is extended, and the clutch is turned on.

This causes the fuming working machine 300 to rise as the drum 312 winds the wire 312A, and the rising end sensor 202 causes the fuming working machine 300 to rise.
Winding is performed until the completion of the rising of is detected. When the completion of ascent is detected, the hoisting is finished, and the fuming working machine 300 is released from being pulled by the wire 312A. At this time, the stopper 21
The end 217A of 7 is projected to the passing position of the locking roller 302Z by the spring 218, but this roller once kicks the stopper to pass. Therefore, the stopper 217 becomes the locking roller 302.
By supporting Z from the lower side, the downward movement of the fuming working machine 300 is suppressed and held in a fixed position.

Further, while the fuming working machine 300 maintains the ascending completion state, in other words, while it is in the fixed position, air pressure is applied to the work mode display button 406A that displays the fixed position, and it is displayed in a protruding state. There is.

Particularly, when the emergency stop button 414A is pushed to switch the emergency stop valve 414 from the position 414X to the position 414Y, air pressure is applied in the direction of arrow C4, the clutch switching valve 412 is driven via the shuttle valve 453, and the air of the dog clutch 313 is driven. The cylinder 314 is driven in the clutch-on direction to move the hoisting machine 310 and raise the fuming working machine 300. In other words, by pressing the emergency stop button 414A in any case, the fuming working machine 300 is raised and held at the fixed position as described above.

The compressor 320 has a belt 322 on its input pulley 323.
Although power is transmitted from the output pulley 321 via the belt 322, a tension clutch 324 is provided on the belt 322.
By making the solid line state of FIGS. 1 and 5 against 212,
A tension force is applied to the remote control wire 220 to turn on the tension clutch 314 to apply a tension to the belt 322 to transmit power. In other words, the compressor 320 is operated only when the traveling body 211 is grounded.

Further, in the hammer unit 308, since the eccentric cam 308B is constantly rotated, when the nozzle 328 of the driving pipe 327 is in the grounded state, the hit portion 329 comes into contact with the eccentric cam 308B and is hit, and the driving pipe 327 is hit. Is driven into the soil and the face cam 330
Cam protrusion 331 is lowered until it hits the lower edge sensor 216,
The driving pipe 327 is driven to a depth suitable for fumarolic work.

Further, when the squirting work machine 300 is in the ascending state, the hit portion 329 lowers against the spring 329A due to the weight of the driving pipe 327, so that a gap is formed between the hitting portion 329 and the eccentric cam 308B and hitting is not performed.

When the fumarolic work at one place is completed, it moves to the next soil loosening point in sequence.
300 is elevated relative to the mounting frame body 200 and is in a fixed position, the traveling body 211 of the mounting frame body 200 remains in the grounded state, and the mounting frame body 200 is not raised.

Therefore, in the field within one section, the mounting frame body 200
Can continuously perform an insufflation work while the traveling body 211 is in the grounded state.

In addition, when the mounting frame body 200 is moved upward by the mobile agricultural machine 100 in a state in which the fuming working machine 300 is in the fixed position as described above, the traveling body 211 is brought into a non-grounded state, and the fuming working machine 300 is held at a predetermined position. When the work start button 413A is pressed, the fuming working machine 300 is not lowered and is switched to a non-working state.
