Description

[Detailed Description of the Invention] This invention involves installing an air blower in the tiller to restore the air permeability and drainage of the hardened tiller around the roots of rare crops such as fruit trees. This device is used to blow out pressurized air from the lower part of the plow to expand and soften the plow, and also to supply air into the ground.

In order to improve work efficiency, in plowing machines and plowing machines, which are equipped with multiple tilling mechanisms to process plows in multiple desired locations, the actual condition of the tillers and the area around the roots of fruit trees can be checked. If the air blower can simultaneously blow and eject pressurized air to the necessary locations depending on the topography, etc., work efficiency can be further improved.

Therefore, in this invention, the necessary number of blowing operation members for blowing in pressurized air can be integrated into one another, or each can be operated independently using a multilayer joint. It is structured and long enough to be connected.

The specific structure will be explained based on an example shown in the drawings. As shown in the side view in Fig. 1 and the rear view in Fig. 2, the device is formed by bending a vibrator material. A compressor (2) and an air reservoir (3) (

between the stays (22) (22) fixed to the mounting plates (14) (14) and the horizontal rod (18), which are fitted to the stays (22) (22) and fixed to the mounting plates (14) (14) so that the tilling mechanism (I) can be moved in the front and back direction by fitting into the Nibane (23)
Also, the stays (24) loosely fitted into the rear end openings (20e) (20e) of the front and rear rails (20) (20) and the stays (25) fixed to the mounting plates (14) (14) ) J and the springs (26) (26) are tensioned to prevent the tilling mechanism (1) from coming off the front and rear rails (20) (20). The driving mechanism (K) operates through the inner hole (2) of the guide tube (27) fixedly installed at the bottom of the air tank (9) as shown in
7a), tightly fit the upper part of the air blowing body (8) into the guide tube (2).
When the striking piston (28) strikes the head of the air blowing body (8) by a striking mechanism such as a known air hammer (not shown) installed in At this time, the tilling mechanism (I) also moves downward along the vertical rails (13) (13), and the supply of pressurized air to the striking piston (28) is as follows: The air reservoir (3) is operated via the switching valve (A) and the driving valve (B) as shown in Fig. 6 by means of the upper hose (not shown), and the piston of the lifting cylinder (16). The pressure air to (16a) is configured to be supplied to the lift valve (C). That is, as shown in Figures 2 and 3, a switching valve (A) and a lifting valve (C) are installed in parallel on one vertical rail (13), and fixed to this vertical rail (11). Connect the ground detector (20) with the pin (21) to the installed bracket.
As shown in Fig. 7, the push plate (30a) of the grounding detector (30) is connected to each spool (a1) of the switching valve (A) and the lifting valve (C) by means of a spring (31). , (c1) are provided so that they can be pushed, and in the condition of sound, the pressurized air in the air reservoir (3) (3) is transferred to the lifting cylinder (1) via the lifting valve (C).
θ, and connect it so as to release the pressurized air from the air pipe up to the injection valve (B) to the main 9, and also to the receiving plate r1.
When the device frame (1) is moved down significantly to the position where 3 touches the ground,
As shown in Fig. 7, since the grounding detector (3 (spring C31) is freely extended, the pushing plate (leg) is connected to the sprue A (at).
.

(cl), and in the ζΩ state, the lifting cylinder (16) K remains: the pressure and empty space are released to the atmosphere from the hold valve (9), and the pressure air in the air reservoir (3) C3 is configured to be supplied to the injection valve (Y) via the switching valve (A).

In addition, as shown in Figure 4, the driving valve (B) is attached to the driving mechanism (for example, the guide cylinder), and a resilient actuation piece such as a rubber plate is attached to the nearby vertical rail (3). When the metal fittings (321 are used to fix the air blower,
Although not shown in the drawings, pressing the button closes the passage from the switching valve (a) to the toy2g. In addition, an air jet valve (l) is attached to the guide tube (27), and the air blower valve (l) is installed near the driver's seat of the traction rack (4).
Fix the mounting seat C=Jf in Figure 8 7 on the instep, and install the mounting seat C3 upright. Driving mechanism 0 of K said husband↑

5-(7) is pivotally mounted around the bottle (3), and is attached to the waving operation lever (36), and the wire C
1 to the actuating lever pedestal which is pivotally connected to the guide tube (27) K in Fig. 9, and by turning the blowing operating lever (12) in the direction of the arrow in Fig. 9, the operating wire (11) is pulled and the actuating lever (11) pushes the spool (d) of the air jet valve (D), which opens the σ ball (d1) so that the pressure chamber of the air tank (9) is passed through the passage ( g) to the passage (8a) of the air blowing body (8), and the lower blowing hole (8b)
It is designed to erupt from.

As shown in FIG. 9, each operating wire (31) is connected to the interlocking block (4
0) is fixedly installed, and a connecting body (41) with a U-shaped cross section surrounded by one interlocking block (40) is connected to its operation wire (38).
), and if this connecting body (4I) is rotated in the arrow direction from the position shown in Fig. 10, the other operating wire (2) will fit into the notch groove (41a). The connecting body (41) is fitted onto the other interlocking block (40) of the lever, and when this fitting is done, one of the operating levers (36) is rotated in the direction of the arrow. For example, when the operating wire (11) is pulled, the other locking block (
40) is also moved and the operating wire (11) is also pulled, the coupling device (1I) consisting of the coupling body (1I) mentioned above and the locking blocks (40) and (41) is moved. ). Although this connector (F) is not shown in the figure, it is. For example, a removable connecting pin may be used to connect both blow-in operation levers (36) (36) into one body, or the blow-in operation member (N) may be the above-mentioned static ejection valve (D). It is also possible to form the air blowing valve (D) into an electromagnetically actuated type so that the air blowing valve (D) is electrically actuated to blow out the air. The compressor (2) of the pressurized air supply mechanism (C) controls the rotation of the PTO shaft (42) of the traction machine (4) between the universal joint shaft (43), the input shaft (44), and the pulley (45) ( 46) and a conduction mechanism (47).

When entering the explosives base, lift the lift arms (7) (7) and raise the equipment frame (1) to a height where at least the ground detector (30) is sufficiently far from the ground. If you raise it,
The push plate (30a) is moved by the spring (31) shown in Figure 7 of the rod.
pushes the spool (c1) of the lifting valve (C), so the pressurized air in the air reservoir (3) (3) is supplied to the lifting cylinder (11) K via the holding valve (C) and its piston. (16a) protrudes and sufficiently lifts the tilling mechanism (I),
The air blower (8) will escape from underground. or,
With this upward movement of the tilling mechanism (J), the spool (b) of the driving valve (B) is released from the pushing force by the actuating piece (f), but on the other hand, the spool (al) of the switching valve (A) is the actuating plate (3
0a), the force air in the air reservoirs (3) (3) is shut off by the switching valve (A) (four paths to the striking stone (28)), and the driving operation is stopped. Therefore, the traction machine (4) is moved, the air blowing body (8) is positioned above the desired tilling position, and the lifting mechanism (H) of the traction machine (4) is moved. ) and operate the bar in the downward direction to rotate the lift arms (7) (7) downward, the equipment frame (1) will also move downward, and first the grounding detector (30 ) is grounded, so lift valve (C) is connected as shown in Figure 6.
The spools (c1) and (a1) of the switching valve (A) are also released from the pushing of the pushing plate (30a), so the lifting cylinder (
The pressurized air in 16) is discharged into the atmosphere from the exhaust hole (c2) of the lifting valve (C), and the tilling mechanism (I) also moves downward with the retraction movement of the piston (16a). )
The lower end of is immediately grounded.

In addition, the pressurized air in the air reservoirs (3) (3) passes through the switching lift (A) and the driving valve (B) to the driving mechanism (L)'s driving rest toy (1).
6), the air blowing body (8) is struck to start the driving process, and the plowing plate is gradually crushed, expanded and softened. Then, the tilling mechanism (I) operates the vertical rail (1
3) When the air blowing body (8) gradually penetrates the lower part along (13) to a predetermined depth as shown in FIG. Although not shown in the drawings, the driving stroke ends because the pressurized air flowing from the switching valve (5) toward the striking piston (28) is closed. Therefore, if the blowing operation lever (26) is operated depending on the operating date, the air blowing valve (D) will open and the pressurized air in the air tank (6) will flow from the passage (g) to the passage (8a) of the air blowing body (B). The air flows into the ground and is vigorously ejected into the ground from the lower blowholes (8b), causing air to penetrate into the crushed plowing platform and causing it to swell and soften sufficiently. After blowing out a predetermined amount of pressurized air into the ground, operate the operating lever of the suspension mechanism again to lift the equipment frame (
1) and then move to the next work area.

Since the air blowing operation device in the tiller expansion and softening device according to this invention is constructed as described above, the air blowing operation device is configured as described above, and the air blowing operation device is configured as described above. It becomes possible to connect them integrally and operate them simultaneously, or it becomes possible to operate each blowing operation member (N) independently from each other without using this connector (F). Therefore, the connecting device (F) can be used to blow in pressurized air from all the air blowers depending on the degree of hardness or softness of the part of the tiller, the topography near the fruit tree roots, etc., making the blowing operation extremely easy. It became possible to operate the member (N) in a negative direction.
