Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a vibrating ridge painting device that is attached to a tractor or the like and mechanically creates ridges in rice fields.

(B) Prior Art Applications have been filed for technologies relating to vibrating ridge coating equipment.

However, in the conventional vibrating ridge coating equipment, the vibrating body for vibrating the shaping plate is elastically suspended and supported from the ridge coating frame by a vibration isolator.
If this resonates and abnormally vibrates in the rotation range that occurs during ridge coating vibration, or if the shaping plate is pushed backwards due to resistance from the mud, it may move too far backwards, damaging the vibration isolator, or causing vibrations. There was a problem in that the vibrating body A was pulled too much and the support part was damaged.

(c) Problems to be Solved by the Invention The present invention solves the problem of the vibration-generating body in the vicinity of the resonance rotation speed when the resonance frequency or resonance rotation speed that causes such abnormal vibration is known in advance. A resonance rotation avoidance clutch is installed on the vibrating body drive shaft to stop rotation, or power is transmitted in the normal rotation speed range, but rotation is not performed in unnecessary rotation speed ranges that are likely to induce resonance above and below. In this way, a high/low rotation stop clutch is installed on the input shaft.

(d) Means for Solving the Problems The problems to be solved by the present invention are as described above, and the means for solving them will now be explained.

In a vibrating ridge coating device that applies mud to ridges by vibrating the shaping plate 1 with a vibrating body A, the resonance of the vibrating body A is placed on the path of the vibrating body drive shaft 32 that drives the vibrating body A. It is equipped with a resonance rotation avoidance clutch C that interrupts power transmission in the rotational speed range.

Furthermore, in a vibrating ridge coating device that ridges muddy soil by vibrating the shaping plate 1 with a vibrating body A, an input shaft 3 transmits power from a PTO shaft of a tractor to the vibrating ridge coating machine.
3, a high/low rotation stop clutch D is interposed to cut off the power in a rotation speed range lower than the operating rotation speed range and in a rotation speed range higher than the operating rotation speed.

(E) Embodiment The problems to be solved by the present invention and the means for solving them are as described above.Next, the structure of the embodiment shown in the attached drawings will be explained.

FIG. 1 is a plan view of a vibrating ridge coating device of the present invention attached to a tractor work equipment mounting device, FIG. 2 is an enlarged rear view showing the specific configuration of the vibrating ridge coating device, and FIG. 3 4 is a plan sectional view showing the configuration of the resonance rotation avoidance clutch C, FIG. 5 is a rear sectional view, and FIG. 6 is a rear view showing a configuration in which the vibrating body A is driven by other power. It is a diagram.

The vibration Nicho painting station of the present invention is attached to a three-point link type work equipment mounting device for a tractor, which is constituted by a top link and a lower link.

The rear end of the universal joint connected to the PTO shaft of the tractor is connected to the input shaft 33 via the high/low rotation stop clutch D, which is a main part of the present invention, to transmit power.

The input shaft 33 passes through the main body frame 10 of the vibrating ridge coating device and protrudes rearward, and the rear end of the input shaft 33 has a check mark to check whether the rotation speed of the input shaft 33 is within the resonance rotation speed range. A rotation speed sensor 34 is attached to detect the rotation speed.

An alarm buzzer 41 is attached to the front part of the main body frame 10 to issue an alarm when the rotation speed detected by the rotation speed sensor 34 reaches a dangerous state.

Furthermore, in the front part of the main body frame 10, there is a clutch that extinguishes smoke only when the clutch is engaged by the high/low rotation stop clutch D, and issues a warning when rotation is stopped in a rotation speed range that induces resonance. A disconnect lamp E is provided.

Two sprockets 60 and 62 are fixedly mounted on the input shaft 33, and the sprocket 60 transmits power to a sprocket 61 on the speed increasing shaft 38.

A pulley 65 is fixed to the part where the speed increasing shaft 38 protrudes into the main body frame 10, and the belt wound around the pulley 65 is attached to the pulley 6 on the scraping drive shaft 35.
6 is being driven.

Further, a sprocket is fixed to a portion of the scraping drive shaft 35 that projects forward of the main body frame 10, and the slope scraping shaft 67 and the top surface scraping shaft 68 are driven by the sprocket.

A slope scraping rotary body 6 is fixed to the cough slope scraping shaft 67, and an upper surface scraping rotary body 7 is attached to the upper surface scraping shaft 68.

The slope scraping rotor 6 has a scraping claw 6 at a 180 degree position.
b and the scraping rod 6a protrude.

Further, the upper surface scraping rotary body 7 is also provided with a scraping claw 7b and a scraping rod 7a projecting at a position of 180 degrees.

The scraping nails 6b scrape off the old ridges, and the scraping rods 6a create scratches on the exposed new soil surface to improve the adhesion of the muddy soil to be applied next.

Similarly, the actual scraping off of the upper surface of the ridge is performed by the scraping claw 7b, and deep scratches are made on the newly exposed soil using the scraping rod 7a, thereby improving the adhesion of the mud applied to the upper surface.

In addition, another subrocket 62 fixed on the input shaft 33
The chain is connected to the sprocket 6 of the mud throwing drive shaft 40.
It is wound between 3.

On the mud throwing drive shaft 40, the mud tilling claws 2 and the throwing rotary plate 3 are closely fixed.

A chain cover 14 that covers the chain wound between the sprockets 62 and 630 is attached to the rear surface of the main body frame 10.

Further, a pulley 65 fixed on the speed increasing shaft 38 simultaneously drives a pulley 64 of the vibrating body drive shaft 32.

The vibrating body drive shaft 32 is connected to the Beher gearbox II.
The direction is changed within the shaft, and the power is transmitted to the vibrating body A via the flexible shaft F.

In the present invention, in addition to or in place of the high-low rotation stop clutch D, a resonance rotation avoidance clutch C is disposed on the vibrating body drive shaft 32.

In the case of the above-mentioned high/low rotation stop clutch D, the rotation of the scraping drive shaft 35 and mud throwing drive shaft 40, which do not vibrate due to the clutch disconnection lamp E, is also stopped at the same time, so when restarting, the torque is Therefore, only the drive mechanism of the vibration generating body A should be stopped in the resonance rotation speed range (a resonance rotation avoidance clutch C is provided).

As shown in FIGS. 4 and 5, the resonance rotation avoidance clutch C is constructed as a mechanical centrifugal clutch that connects and disconnects the clutches by centrifugal force.

As shown in Fig. 4, the resonance rotation avoidance clutch C is composed of 2 & 1 centrifugal force clutches: a low-speed stop clutch C1 and a high-speed stop clutch C2. The structure is such that driving of the vibrating body A is stopped in a high rotational speed range.

By adjusting the disconnection rotational speed range of the low-speed stop clutch C1 and the high-speed stop clutch C2, it is possible to stop the rotation of the vibrating body drive shaft 32 only in a previously anticipated resonance rotational speed range.

On the other hand, the high/low rotation stop clutch D interposed on the input shaft 33 described above is constituted by an electromagnetic clutch device that inputs and judges the electrical signal of the rotation speed sensor 34 and connects/disconnects the solenoid based on the output signal. There is.

The high/low rotation stop clutch D leaves only the normally used rotation speed range of the vibrating ridge coating machine and does not require the other upper and lower parts, which may cause resonance, so a solenoid is used to stop the rotation. In contrast, the resonance rotation avoidance clutch C is configured to stop the rotation of the vibrating body drive shaft 32 in the resonance rotation region in the low rotation region.

Further, a double mountain-shaped scraping cover 17 is covered above the rotating parts of the slope scraping rotary body 6 and the upper surface scraping rotary body 7 described above.

In addition, a guide plate 4 for making mud that has been tilled by the mud tilling claws 2 and thrown by the throwing rotary plate 3 and the throwing plate 3a falls onto the scraped ridge from above the throwing trajectory. is placed toward the outer end surface of the

Further, a mud cover 24 is arranged along the outer periphery of the rotation locus of the mud tilling claws 2 and the throwing rotary plate 3.

From below the main body frame 10 or the chain cover 1
A gutter body 8 is provided in a protruding manner on a support body protruding from below the base plate 4, and the gutter body 8 supports the entire body during normal ridge coating work.

However, the gutter body 8 cannot be moved if it is not attached to a tractor, so a twin-tailed wheel I6.
G and a single tail wheel 15 are detachably attached.

These twin tail wheels 16, 16 and single tail wheel 15 are necessary when only the vibrating ridge coating machine is moved, and are removed when ridge coating is to be performed.

An adjustment screw tube 21 is fixed to the end of the support fitting 70 that protrudes from the main body frame 10 so that it can be folded down.
By rotating the ridge coating position adjustment lever 9 through an adjustment male screw 2° screwed into the main body frame 10, the positions of the mud guide plate 4 and the shaping plate 1 etc. can be moved vertically in parallel with respect to the main body frame 1O. It can be done.

When the ridge coating position adjustment lever 9 is rotated, the slope scraping rotary body 6, the upper surface scraping rotary body 7, the scraping cover 17, the mud guide plate 4, and the shaping plate 1 are moved in parallel up and down together with the male adjustment screw 20. and vibrating body A, etc.

A parallel movement link mechanism is arranged on the rear surface of the main body frame 10 so as to move vertically in parallel along the slope of the ridge.

The upper and lower parallel links 13, 12 are connected to pivot shafts 27, 29,
It is pivoted at four points 26 and 28, and the pivot shafts 29 and 28
This part is pivotally supported by the rear plate part of the mud guide IFi4.

Therefore, when the adjusting male screw 20 is expanded and contracted up and down by rotating the ridge coating position adjustment lever 9 with respect to the adjustment screw tube 21, the upper and lower parallel links 13 and 12 move up and down, and the portion that contacts the ridge is It moves parallel up and down.

A ridge coating frame 5 is fixed to the adjustment male screw 20 and protrudes forward and backward.

Then, the vibrating body A is suspended from the ridge coating frame 5,
The shaping plate 1 is fixed to the vibrating body A.

Since the vibrating body A is driven by the above-mentioned flexible shaft F and vibrates up and down, it cannot be fixedly supported and needs to be supported suspended from the ridge coating frame 5. .

As shown in FIG. 3, a stopper rod 31 is provided as a part of the regulating body so that the part of the shaping plate 1 suspended and supported from the ridge coating frame 5 does not flow backward.
A stopper elastic body 30 is attached to the inside of the rod 31.

In FIG. 6, the vibrating body A is driven by a separately arranged prime mover G.

By driving only the part of the vibrating body A with a separate prime mover G, the operation of adjusting the rotational speed of the vibrating body A to a rotational speed that does not cause resonance can control the speed of the tractor and the rotation of the PTO shaft of the tractor. This can be done arbitrarily regardless of the number of rotations, and the operator first starts the prime mover G, sets the rotation of the vibrator A to the normal operating speed that does not cause resonance, and then starts the tractor. The PTO shaft can rotate the scraping drive shaft 35 and mud throwing drive shaft 40 of the vibrating ridge coating machine.

This eliminates the problem of unexpected resonance occurring in the vibrating ridge coating machine when increasing the rotational speed of the tractor's engine or increasing the traveling speed.

(F) Effects of the Invention Since the present invention is constructed as described above, it has the following effects.

In the vibrating ridge coating device that ridges mud by vibrating the shaping plate l with the vibrating body A, as claimed in claim (1), on the path of the vibrating body drive shaft 32 that drives the vibrating body A. In addition, a resonance rotation avoidance clutch C is installed that interrupts power transmission in the resonant rotation speed range of the vibrator A, so that the drive of the vibrator A stops in the resonant rotation speed range predicted from the beginning, making it easier to control the vehicle. This makes it possible for the operator to raise the rotation speed to the normal operating speed without worrying about passing the resonant rotation speed without worrying about the accelerator lever.

Also, even if you accidentally reduce the rotation speed of the tractor's PTO shaft to the resonance rotation speed range, it will not rotate in that rotation speed range, so
This makes it possible to avoid damage to the shaping plate l due to resonance and damage caused by collision of the vibrating body A with other parts.

As claimed in claim (2), in a vibratory ridge coating device that ridges mud by vibrating the shaping plate 1 with a vibrating body A, an input shaft transmits power from a PTo shaft of a tractor to the vibrating ridge coating machine. 33 is equipped with a high/low rotation stop clutch D that cuts off the power in the rotation speed range lower than the operating rotation speed range and in the rotation speed range higher than the operating rotation speed, so the rotation speed is lower than the normal operating rotation speed range. Since the drive of the vibrating ridge coating machine can be stopped in both high and low rotation speed ranges,
The vibrating ridge coating machine can be stopped in both low and high rotation speed resonance areas to prevent dangerous situations from occurring.

In addition, by installing a high/low rotation stop clutch D in the input shaft 33, both the scraping drive shaft 35 and the mud throwing drive shaft 40 stop rotating in the resonance region, so the operator can control the vibration type ridge coating machine. This eliminates the fear of starting the ridge coating work when the shaping plate 1 is not vibrating because it can be detected that it is not being driven normally.
