Description

DETAILED DESCRIPTION OF THE INVENTION This invention provides hardened U around the roots of crops such as fruit trees.
In order to restore the permeability and drainage of the tiller, an air blower is installed on the tiller, and pressurized air is ejected from the lower part of the tiller to inflate and soften the tiller. This invention relates to a tiller expansion and softening device.

In order to effectively expand and soften the tiller at a sufficiently deep position from the ground surface, the air blower (1υ) must be sufficiently injected (F1). For example, in order to secure this gastric penetration length, that is, the penetration stroke, by using a lifting mechanism σ-◇ such as a 3P link mechanism provided in a traction machine such as a tractor (4+), the third time mechanism a-1
A guide mechanism (K) connected to By lowering the guide mechanism σ9, the lower end of the air blowing body 01 is brought into contact with the ground, and the air blowing body (111) is driven in a straight line to a predetermined depth shown in FIG. 3' by the driving mechanism. However, when pulling out the tilling mechanism (T,) in the penetrating state, the tiller I+r<(1) will move in an arc, causing the air blowing body (101) to move. A lateral force will act, and as shown in Figure 1, the movement 1111
Install the air blower 11 at a height 11) that does not interfere with one crop.
In order to lift the traction machine (11), a holding mechanism equipped on the traction machine (4) is configured to be supported at the upper end of the piston of the lifting cylinder, and the piston is In the downward movement state, the air blowing body is driven straight into the ground via the guide mechanism, and the air blowing body in the penetrating state is pulled out straight and smoothly by the upward movement of the piston. In this way, the air blowing body is held in an upward position relative to the equipment frame, so even if the amount of lift by the lifting mechanism is small, it can be raised to a height that does not hinder movement:
1) is ensured, and since the upper end of the piston is not fixed to the tilling mechanism but simply supporting the tilling mechanism at this upper end, the purchase of the air blower is The ability to divide the input stroke into the lifting amount by the piston and the lifting amount by the lifting mechanism by dividing the button makes it possible to reduce the stroke amount of the lifting cylinder (the piston,
(Compared to the one in which the upper end is fixed to the tilling mechanism), the lifting cylinder has been devised to be shorter and smaller 1

The supply of pressurized air to the striking piston On is carried out from the air reservoir (2) by an air hose (not shown) via the switching valve (4) and the driving valve (1()) as shown in Fig. 11. Also, there are seven cylinders (23 pistons)
The pressure air to η is configured to be supplied to the lifting valve ((). In other words, as shown in FIG.
Install the switching valve (changeover valve) and lifting valve (Q) in parallel, and pivot the grounding detector G to the bracket (7) fixed to the horizontal lever at the base of the bottle. The push plate (39a) of the 4i grounding detector (l) is connected to the spring (4 (FI2) (C2) is provided so that it can be pushed, and in this state, the pressurized air in the air reservoir (2) (2) is supplied to the lifting cylinder (271) via the lifting valve (C), and When connecting the air pipe up to the injection valve (D) so as to release the pressurized air to the atmosphere, and moving the device frame (1) down to the position where the receiving plate (1e) is in contact with the ground, as shown in Figure 11. As the grounding detector 01 freely extends the spring (1), the pushing plate (39a) separates from the spool (C2) (C2), and in this state, the lifting cylinder r23

In addition, the code|symbol (e) is a roller.

In addition, the driving valve (for example, the guide cylinder C%lK of the driving mechanism (11) is attached as shown in Fig. 9, and a resilient actuating piece (f ) using the mounting bracket (41), and the air blower (when the II reaches the specified insertion depth, the actuating piece) connects to the driving valve (B).
Although not shown in the drawings, the passage from the switching valve (5) to the striking piston Gη is closed. In addition, by attaching an air jet valve (gull) to the guide tube (7) and operating the operating lever (4 moats) installed near the driver's seat of the towing machine (4), the ladder wire (4 moats) can be activated.
4 The actuation lever (4 force pushes the spool (I) of the air jet valve (R) and the ball (I) of the air jet valve (I)
When the air tank (13) is opened, the pressure air from the air tank (13) is supplied from the air blower (+1 passage (10a) K) through the passageway (1), and is ejected from the lower blowout hole (10h)... The receiving plate (IIK is a rubber plate attached above or below the receiving plate (10) with a large hole (16a) through which the air blower (II) can freely move up and down as shown in Fig. 13. This hole (1 turn) is closed with a flexible closing plate (4!1), and the air blowing body is tightly fitted into the four holes (2), so the air blowing body ( During the pawning operation of In, even if this air blowing body (1tm) moves slightly in the front and back or left and right directions due to collision with, for example, pebbles underground, the large λ hole in the receiving plate Oe ( Since the air blowing body Q (e does not come in contact with
This long air blowing body (11) is supported by its hole (45R), and the lower part of the air blowing body (11) functions as a guide to be vertically inserted into the ground, and during the underground penetrating operation. Even if there is some movement in the air blowing body as mentioned above, the force of the hole (4!'n) is always brought into close contact with the air blowing body (IIK), and this air blowing after penetrating to a predetermined depth. It is constructed so that the pressurized air that blows out from the body (the blowout hole (1α) of 111) does not freely blow out to the ground surface through the small gap between the air blowing body (11) and the penetration hole formed in the ground around it. do.

As shown in FIG. 14, as another example of how to attach the lifting cylinder 14Q and its piston (and others), the lower part of the lifting cylinder (Am) is attached to the horizontal rod (4FIJ through the bracket 4η). (Pivotally attached to 41, air tank f

When the head (2, 1) moves upward, it comes into contact with the upper bottom (51a) K of the cylinder GO, and the tilling mechanism (1) is configured to be able to move through this head (c). When the lower end of the air blower 0 is in the ground position, the stroke of the piston (4Fla) is made short enough to leave a gap (a) between the head 12.1 and the upper base (51a). -In addition, the air tank [13]

When working, raise the lift arm (8181) and lift the equipment frame (1) to a height where at least the grounding detector OI is sufficiently far from the ground surface, then the 51/C as shown in Figure 12 Since the pushing plate (C) pushes the spool (C2) of the lifting valve (Q) by the spring 0 (J), the air reservoir (2) (
2) Pressure air is supplied to the lift cylinder C2 via the lift valve (Q).
``3, its piston (no) protrudes to sufficiently hold the tilling mechanism (1), and the air blowing body (11) escapes from the ground. Cultivation mechanism (I
), the spool (b) of the driving valve (I3) is released from the push by the actuating piece (f), but on the other hand, the spool (C2) of the switching valve (A) is moved upward by the actuating plate (39a). ), the pressurized air in the air reservoir (2>(2) is transferred to the switching valve (
5) closes the flow path to the striking piston Qn (therefore, the driving operation is stopped. Therefore, the traction machine (4) is moved to blow air above the desired tilling position. Align the blowing body and operate the operating lever of the lifting mechanism of the traction machine (4) in the downward direction to lift the lift arm (8) (
If you rotate $'l) downward, you can install @ll! The frame of will also move downward, and the grounding detector (31) will touch the ground first, so as shown in Fig. 11, K, lifting valve (q) and spool (C2) of the switching valve (4) In order to be released from the pushing of the pushing plate, the pressurized air in the lifting valve (Q) is discharged into the atmosphere from the exhaust hole (C3) of the lifting valve (Q).
Since the tilling mechanism (I) also moves downward along with the retracting operation of the piston (22a), the lower end of the air blower (11) immediately touches the ground.

In addition, the pressurized air in the air reservoir r2) (2) is supplied to the striking piston (37) of the striking mechanism via the switching valve (4) and the blowing valve (kalo), and the air, air, blowing body ( +(+ is struck to start the driving process, and the tiller will gradually crush and swell.Then, the tilling mechanism (I) will move the vertical rail 0η(
171 until it reaches a predetermined depth as shown in FIG. Therefore, although not shown in the drawing, the pressurized air flowing from the switching valve (A) to the striking piston CSnK is closed, and the driving stroke ends. Therefore, the operating operator can use the control lever (
4 When the hot water is operated, the air blowing valve (1) opens and pressurized air from the air tank (11) is released from the air blowing body (11) from the passage (,9).
0 [Th], the lower nozzle (10b)...
・Air is ejected forcefully into the ground and permeates the crushed plowing platform, causing it to swell and soften sufficiently. Once the predetermined amount of pressurized air has been ejected into the ground, the machine frame (1) is lifted up again by operating the operating lever of the lifting mechanism, and moved to the next work area. I get busy when I move. ``Then, when the device frame (1) is lifted, the 5 pushing pieces (39a
)'s spool (C2) must be adjusted so that it occurs at the same time as the spool (C2) of the lift valve (Q), or earlier. During the lifting operation, the switching valve (5) closes the passage to the driving valve (duck), and during the lifting and pulling operations of the air blowing body (11), the switching valve (5) closes the passage to the blowing piston θD. This prevents the risk of dry firing due to the supply of pressurized air.

It should be noted that the above-mentioned driving mechanism f11), lifting mechanism (c), etc. may be of a known type other than the illustrated example, and the purpose of the present invention can be sufficiently achieved. Included valve (
6), F valve (q also has a grounding detector <31 as shown in the example)
In addition to an air valve structure in which switching is performed directly at the ground detector 01, for example, an electric switch may be operated by the ground detector 01 to open and close an electromagnetically actuated air valve *q.

As described above, the tiller expansion and softening device according to the present invention includes the tilling mechanism (I) that blows pressurized air into the air blowing body (43 underground), and the tilling mechanism (I) that blows pressurized air into the air blowing body (+111). A pressurized air supply mechanism (1), a device frame (1) suspended from the suspension mechanism (4) of the traction machine (4) so as to be able to rise and fall freely;
In this tiller expansion device, which consists of a guide mechanism (8) that guides the tilling mechanism (I) to the device frame (1) so as to be able to move up and down in a straight line, a cylinder and its piston are connected to a lifting cylinder. is attached to the equipment frame, and the tilling mechanism is supported at the upper end of the piston of this lifting cylinder, so when the piston (no) is moved downward, the guide mechanism (
The air blowing body (11) will be driven into the ground in a substitute line shape through S), and the air blowing body (II) in the penetrating state will be pulled out straight by the upper wtb movement of the piston (22a). As a result, the air blower (11) can be driven in and pulled out smoothly without any lateral force acting on the air blower (11).In this way, the air blower (1 (- Since the upper end of the piston is held in an upwardly moved position, a height (h) that does not interfere with the moving operation can be secured even if the lift by the lifting mechanism I is small. The tilling mechanism (I) is not fixed to the tilling mechanism (1) and is simply supported at its upper end, so that the penetration stroke of the air blowing body (11) is performed by lifting by the piston (731). In addition to being able to separate the phases into the amount of lift and the amount of lift by the lifting mechanism σ, the stroke of the lifting cylinder (to) can be made smaller, and the upper end of the piston is fixed to the tilling mechanism. The one of this invention was able to shorten the lifting cylinder 03 compared to the previous one.
