Description

[Detailed Description of the Invention] This method is used to restore the air permeability and drainage of hardened 491 rock around the edges of crops such as fruit trees. This invention relates to a control device for the driving operation of an air blower in a tiller expansion device used to expand and soften the tiller by blowing out pressurized air from the lower part of the tiller and supplying air into the ground. be. ′ □ In order to automatically start the driving operation of the air blowing body, this air blowing body is installed. In addition, in the case of a tiller expansion device that is configured to start the driving operation and equipped with multiple tilling mechanisms to improve efficiency, if there are local unevenness on the surface of the tilled soil, the device When lowering the machine frame to carry out plowing, the surface of the convex plowed soil is covered with plowing! Only the mechanism operates, resulting in areas where no crushing or crushing is performed, resulting in a significant improvement in efficiency, or when some parts of the tilling mechanism are operated, the equipment may Inconveniences such as unbalanced force acting on the frame and damage to related members are likely to occur. □ Therefore, in this invention, a plurality of □ cultivating mechanisms that drive air blowing bodies into the ground and blow in pressure air by □ mechanisms are attached to the 11) holding mechanism of the traction machine by lifting and lowering the self-cock tilting Q3 rack. □ In the plowing PR-expansion device, which is installed in the equipment frame so that it can be moved up and down in a straight line through a guide mechanism, when each plowing mechanism moves down to a predetermined height, each ground detector is activated and the driving mechanism described above performs the driving operation.

A clutch mechanism is provided for each tilling mechanism to start the tilling mechanism, and the clutch mechanism is connected in such a way that the grounding operation of any one of these grounding detectors causes the ground driving mechanism to operate at the same time. This is an attempt to solve the above-mentioned inconvenience caused by successive J implantations.

In) so that the center of gravity of its installation coincides with the cylinder center:
It is formed to help the driving force of the driving mechanism (in response to the hardness and softness of the board, so that the pawn operation can be performed quickly).

11) is fixed, a bottle hole (13a) is also provided in the mounting plate (13) on the side close to this, and the holding L cylinder (two-color piston (22a) is projected upward as shown in Fig. When the tilling mechanism (I) is lifted high and the lower part of the air blower (10) hardly protrudes downward from the receiving plate (+cl), that is, when this tiller expansion device is in a moving position. , for example, fixed pin aO to both pins J [[49aX +3a)
) so that the tilling mechanism (1) can be fixed in the lifting position, the amount of lift by the 713 holding mechanism OD of the traction machine (4) can be reduced, and the tilling mechanism (I) can be prevented from moving unintentionally during the moving operation. I try not to.

In addition, in the illustrated embodiment, the pressurized air supply mechanism (1) is attached to the center part of the equipment frame (1), whose center part in the left and right direction is suspended by the 11'J holding mechanism (11). Mechanism (1)
(I) are attached to the left and right sides of the device frame (1) in symmetrical positions, so the balance of the entire device at least in the left and right direction is extremely good, and the device frame is in the upper state. When moving the air blowing body (10) downward, the air blowing body (10) moves downward almost vertically without tilting and can penetrate vertically into the ground surface. With σD, the equipment frame can be smoothly raised without tilting even in the middle of the day, and this plowing platform, which is hung in a large overhang shape behind the traction machine (4), is Since the lateral balance of the device was improved, running stability was also improved.The P T (
1 shaft 6υ and input shaft 6 are connected with 6 universal joint shafts,
Each of the input shaft 62 and compressor (3) -
44) Six are linked by conductor + iQ 561.

During the work, if you raise the lift arm f8) (8) and lift the device frame f11 to a height where at least each ground detector (31) is sufficiently far from the ground, the Spring (4) (Push plate (Th

The pressurized air in the air reservoir (2) (2) is supplied to the lifting cylinder (27J) via the lifting valve (c) and the piston (212
, I) protrude and sufficiently lift the transmission mechanism (I), and the air blowing body 00 escapes from underground. In addition, with the upward movement of the tilling mechanism (I), the drive valve (spool (b)) is released from the push by the actuating piece (f), but on the other hand, the spool (a2) of the switching valve (5) ) is pushed by the actuating plate (I on :3), so the air reservoirs (2) (2

Since the flow path to 7) is closed, the driving operation is stopped.

Then, move the towing machine (4), align the air blower (10) above the plowing position of the new house, and
11 If the operating lever of the holding mechanism (II) is operated in the downward direction to rotate the lift arm (8) (R) downward, the device frame (1) will also move downward, and first, at least 1

) is released from the pushing of the pushing plate (3 (1a)), so the pressurized air in the lifting cylinder (2) is exhausted to the atmosphere from the exhaust hole (c3) of the lifting valve (C'l). Since the tilling mechanism (I) also moves downward along with the retracting action of the piston, the lower end of the air blower 00 immediately touches the ground.
The pressurized air is supplied to the driving mechanism (the striking piston (37) marked) through the switching valve (5) and the driving valve (13), and the air blowing body (10) is struck to complete the driving stroke. This will begin to gradually crush and soften the tiller.

Then, when the tilling mechanism (I) gradually moves downward along the vertical rail f17]-11 force and the air blowing body (1 (1) penetrates to a predetermined depth as shown in Fig. 6, the operating piece (f)
Although it is not shown in the figure, since this pushes the spool (1) of the driving valve (13), the pressurized air flowing from the switching valve (5) to the striking piston C3n is closed, so the driving stroke ends.

Then, when the operating operator operates the operating lever (4 increment), the air blowing valve ff opens and the air tank (1 liter) of pressurized air flows from the passage (g) to the passage (I) of the air blower (Hl).
The air flows into Oa) and is ejected into the ground from the lower blowhole (Job)..., causing air to permeate into the crushed plowing platform, causing it to expand and soften sufficiently. Then, once the predetermined amount of pressurized air has been ejected into the ground,
The operator operates the operating lever of the holding mechanism to lift the machine frame (1) and then moves to the next work location.

When the equipment frame (1) is lifted, the spool (c2) of the pushing piece (39a) is pushed and released at the same time as the grounding detector (31φ) is moved away from the ground surface, or Therefore, during the lifting operation, the switching valve (N) is smaller than that in the illustrated example, and the movement of the tJ according to the present invention is necessary.
As mentioned above, the □ driving operation control device in the F-panel expansion device fi operates when the plurality of tilling mechanisms (I) (I)... move down to a predetermined height, the respective grounding detectors C3! 1 is operated to start the driving operation of the respective driving mechanism (r<).

The latch mechanism is connected to one of these grounding, detector (3!J
The grounding action causes the other driving mechanism (K) to operate at the desired time. ! ,! There is one convexity, so there are multiple one convexities.
Since all the driving mechanisms of the ground detector C (even when only a part of the ground is connected to the ground) are activated, swelling, softening and crushing can be carried out efficiently. In addition, it was possible to eliminate accidents such as the unbalanced force caused by one part of the bolt acting on the equipment frame and breaking the related parts.
