Description

[Detailed Description of the Invention] This invention aims to restore the air permeability and drainage of the hardened tillage bed around the roots of fruit tree crops, by penetrating the tillage bed with an air blowing body. □ also relates to a tiller expansion and softening device used to blow out pressurized air from the lower part to expand and soften the tiller and supply air into the ground.

In order to automatically start the driving operation of the air blower, when the tilling mechanism equipped with the air blower is lowered to a certain height K, the grounding detector is activated. In a tiller expansion and softening device that is configured to start the driving operation and is equipped with a plurality of tilling mechanisms to improve efficiency, if there are local irregularities on the Murakami surface, When working by lowering the machine frame, only the tilling mechanism that extends over the button-shaped Murakami surface starts the driving operation, which creates areas where swelling, soft crushing is not performed, and efficiency is reduced. Moreover, due to the driving operation of a part of the tilling mechanism, there is a concern that an unbalanced force may be applied to the device frame and damage related members.

・Therefore, in this invention, a plurality of tilling mechanisms are provided in which an air blowing body is driven into the ground by a □ mechanism to blow pressurized air, so that they can be moved up and down linearly along a guide mechanism. This guide mechanism can be freely moved up and down within a certain range to the hanging mechanism of the traction machine K/J4 The hanging mechanism of the traction machine can be freely moved up and down within a certain range, and the grounding detector installed in each tilling mechanism can be grounded. It is configured so that the driving mechanism starts the driving operation by the movement, and even if there are localized irregularities on the special surface,

), for example, a rubber plate □, etc., is fixed to the lvl fitting (41), and the air blower 4 is inserted to the specified insertion depth as shown in Fig. 9. When it reaches this point, the J actuating piece (-) pushes the driving □ valve (shock female spool (+)) and closes the passage from the switching valve (5) to the striking piston C3H, although it is not shown in the figure. In addition, install air blower 1 (J valve 11 to t1) in the guide tube (boot), and install the operating lever (4th floor) near the traction machine (4) 9 driver's seat. When operated, the operating lever (4) is activated by the operation wire (44) to the spool (4) of the odor ejection valve (1).

Since the air blowing body fld!'l is tightly fitted into the closing plate (4 long hole (45a)), the air blowing body (10) is closed.
During the direct entry operation, for example, if you collide with a pebble underground, etc. tp Air blowing force: 0 force; Even if it moves slightly in the front and back or left and right directions, the air blower (II) does not contact the large hole (j6a) of the receiving plate (1 (Q). ,
The penetrating operation H will be carried out smoothly, and due to the elasticity of the closing plate (one), this long air blowing body rl (Il

Also, the upper part of the tilling mechanism (1), for example, the air tank (IZ
A mounting seat (4G) is formed on the upper part of the mounting seat (4G), and a weight θη is removably fixed to this mounting seat (40, for example, with a pole eye 4 or...). The number of levers can be increased or decreased, and the center of gravity of the air blower (1φ) is aligned with the center of gravity of the air blower (1φ) to increase the driving force of the driving mechanism (a). Corresponding to the softness of the silk, the penetrating action is made to be carried out quickly.

Also, as illustrated in Figures 6 and 7, one vertical

When the tiller expansion and softening device is moved to a position R such that it hardly protrudes downward from 0, 3b, for example, a fixed bottle 61 is inserted into both bottle holes (49a) and (13a). By making it possible to fix this tilling mechanism (I) in the holding position, the amount of IJ lift caused by the lIS holding mechanism σ0 of the traction machine (4) can be reduced, and the tilling mechanism (I) can be fixed during movement.

Note that the air blowing body (10) freely rotates around its center of gravity with respect to the guide tube α9 of the driving mechanism σ.
However, the direction of the jet hole (101) provided at the bottom of the jet hole (101) is not fixed, and the jet direction of the pressurized air, that is, the direction of the swelling is also not determined. , Op (a), there is a locking groove (1

When working, raise the lift arm (f8
412 As shown in the figure, the spring (41) pushes the push plate (39a)
In order to push the spool (co) of the two valves (Q), the pressurized air in the air reservoir (2) (2) is supplied to the lifting cylinder (2) via the lifting valve (Q) and its piston (22a ) will protrude and sufficiently lift the tilling mechanism (i), and the air blowing body θ1 will escape from the ground.Also, along with H I'& I+ of this tilling mechanism (1). Illumination valve (Ill)
The spool (b) is released from being pushed by the actuating piece (f) button, but on the other hand, the female spool (al) of the switching valve (N) is pushed by the actuating plate (39a), so the switching valve (A ), the flow path from the air reservoir f21f2) to the striking piston 0η is closed, and the driving operation is stopped.

Therefore, move the traction machine +41 and align the air blower fl (+1. (I O)) above the desired plowing position. When rotated downward, the device frame (1)

(Since the vertical rail 11ηC17 can be moved up and down by allowing the movement of the vertical rail 11C17) between the locking pin 413C1 and the locking pin 413C1; Since the spool (cQ', (at) of the switching valve (A) is released from the pushing force of the pushing force L(:aa), the pressurized air in the lifting cylinder (A) is discharged from the lifting valve (Q). The air is discharged into the atmosphere from the hole (C), and the tilling mechanism (1) moves downward along with the retraction operation of the biston (22, l), so that the air blower (1)
(The lower end of the mechanism is immediately grounded. Also, the pressurized air in the air reservoir (212) passes through the switching valve and the driving valve (r3) to the driving mechanism (

1 (not shown since the actuating piece (f) pushes the spool (bl) of the driving valve (B) when the water penetrates, but it moves from the switching valve (A) to the impact piston 137). Since the incoming pressurized air is closed, the driving operation ends.

When the operating operator operates the control levers (A, 9), the air blow-out valve (- opens and 17 J of pressurized air flows from the air tank (g) to the air blower (1 (J passage)). (

As a result, it ejects into the ground with great force, allowing air to penetrate into the crushed plowing platform, causing it to swell and soften sufficiently. After discharging the specified amount of pressurized air into the ground in this way, operate the control lever of the IIs holding mechanism again to release the equipment frame (1).
) and then move to the next work area. In addition, in addition to the above-mentioned switching valve), driving valve 01), and lifting valve (Q), in addition to the pneumatic valve structure that switches directly on the contact detector side as shown in the example, there are also electromagnetically actuated pneumatic valves.

As described above, the tiller 1 expansion and circulation system according to the present invention guides a plurality of tilling mechanisms (1) that blow pressurized air into the pond by driving the air blowing body (10) through the driving mechanism σ.
