Description

[Detailed explanation of the invention] The present invention is a system in which an engine, a power sprayer, and a winder are set on a machine frame so that these three parts can be transported and stored as one unit. It is equipped with a hose reel brake for easy operation during storage, storage, and transportation.

Power sprayers are usually equipped with long hoses to deliver water over a wide area. Since it is difficult to wind up this hose when transporting or storing it after work, many hoses are now equipped with a power-driven winding machine.

This winder rotates only a small amount, and only rotates at the number of revolutions required to wind up the hose, and the rotational speed is extremely slow as care must be taken to avoid twisting the hose. In order to achieve this, a belt tension type clutch device is used as the clutch device, so that the hose reel can be rotated slowly by half-clutching the clutch device.

However, I completely connected the clutch,
When the hose reel begins to rotate properly at its original speed, the weight of the hose wound around the hose reel increases and the inertial force becomes large. The hose may get caught in the hose faster than it can be repaired, the hose may twitch when it is caught on an obstacle and break the hose or nozzle, or the nozzle at the end of the hose may become entangled in the hose reel and break.

In order to eliminate this danger, a brake is provided to brake the rotation of the hose reel in conjunction with the direction in which the clutch lever is released.

In addition, this brake device is equipped with a locking device that locks in the braking state, so that the hose reel moves due to pressure fluctuations in the hose during pest control work or when opening and closing the pot, and the hose that remains wound on the hose reel becomes loose. This eliminates the inconvenience of having to unwind and rewind the entire film when winding it up. Furthermore, by providing this locking device, it is possible to prevent the hose from gradually loosening during transport in a car or during work, which would cause problems in the next winding.

The purpose of the present invention is as described above, and the configuration of the present invention will be explained based on the embodiment shown in the attached drawings.

Fig. 1 is an overall side view of the sprayer with a power winder according to the present invention. Fig. 2 is a front view as well. Fig. 3 is a side view with the clutch lever 5 released and the hose reel brake applied. A side view with the clutch released and the hose reel brake also released. FIG. 5 is a drawing with the clutch lever 5 in the "on" state.

is supported by bearings, and engine 1 and power sprayer 2 are installed at the rear.
are placed above and below. The input pulley 14 of the power sprayer 2 is rotated by the V-belt 23 from the engine pulley 16 of the engine 1, and the pulley 1 on the opposite side is rotated.
5, power is transmitted to the drive pulley 4 of the hose reel 3 via a V-belt 13. The V-belt 1
Power is transmitted by applying tension pulley 7 to 3 and tensioning the V-belt. The power is cut off by retracting the tension pulley 7 using the arm 8.

At the water suction hose 18 to the water suction side of the power sprayer 2,
The liquid agent and the like are absorbed, pressurized, and injected into the shaft pipe of the hose reel 3 through the hose 11 on the discharge side. The shaft pipe is connected to the base end of a hose 22 fixed to the hose reel 3 via a swivel joint, and liquid is supplied thereto.

In this way, in the device, the clutch lever shaft 2
A clutch lever 5 and a lock pedal 9 are pivotally supported on the clutch lever shaft 24. The lock pedal is made by bending a round rod into a U-shape and is welded and fixed to a cylindrical body 25, and the cylindrical body 25 is loosely fitted onto the clutch lever shaft 24. The clutch lever 5 has its lower end connected to the cylindrical body 33.
The arm 12 is also welded to the same cylinder body 33. A brake link 6 is pivotally connected to the arm 12, and the rear end of the brake link 6 is pivotally connected to an arm 11 that is interlocked with an arm 8 of a tension pulley 7. Further, a brake shoe fixing body 26 is fixedly installed inside the brake link 6, and the brake shoe 2 is attached to this brake shoe fixing body 26.
7 is fixed.

Further, a cam plate 28 is fixedly attached to the brake link 6 so as to face downward, and a bent end portion of the brake pedal 9 is engaged in a cam groove of the cam plate 28. The cam groove of the cam plate 28 is configured in an "in" shape, and three fulcrums 28a, 28b, and 28c are provided. Further, biasing springs 20 and 21 are interposed in the arm 12 and the brake pedal 9 to bias them rearward and downward.

In the state shown in Figure 5, when the operator manually rotates the clutch lever forward, the biasing spring 2
The tension pulley 7 is moved to V by arm 12, link 6, arm 11, and arm 8 against the
As the belt 13 rotates in the direction of tension, the hose reel rotates and winds up the hose. This fifth
When the operator releases his hand from the state shown in the figure, the arm 12 is pulled by the biasing spring 20 and rotates in the direction in which the tension pulley 7 is released, and the tension pulley 7 rotates to the clutch disengagement position. Similarly, the brake link 6 also moves in the cutting direction, and the cam plate 2
8 similarly moves to the left, but since the brake pedal 9 is biased downward by the biasing spring 21,
It moves from the locking fulcrum point 28b of the cam groove in the direction of 28a, and is locked at this locking fulcrum point 28a, thereby locking the brake link 6 so that it does not move any further. This state is shown in FIG. In FIG. 4, the clutch is disengaged and the brake is not applied.

For normal hose winding operation, press brake pedal 9.
is reciprocated between the engagement fulcrums 28b and 28a.

When the operator wants to brake the rotation of the hose reel 3, the operator rotates the clutch pedal 5 in the clutch disengaging direction and depresses the brake pedal 9, so that the tip of the brake pedal 9 moves to the fulcrum point 2.
Operate to move up to 8c at once. As a result, the brake link 6 and the brake shoe 27 come into contact with the outer periphery of the pulley 4 and the outer edge of the V-belt 13 to apply braking. Since the braking force can be maintained by the biasing spring 20 even after the clutch pedal 5 is released, the braking state can be maintained during transportation or pest control work.

To release this brake lock state, if the clutch lever 5 is rotated even once in the clutch ``engage'' direction, the tip of the brake pedal 9 will come out from the locking fulcrum 28c and will be urged downward by the urging spring 21. Therefore, even if the clutch lever is returned, it will enter the engagement fulcrum 28a and will not return to the engagement fulcrum 28c, which is the lock position. If you press the lock pedal again, the brakes and lock will be applied.

As described above, the present invention, in which an engine, a power sprayer, and a winding machine are set, can also operate the hose reel brake device in conjunction with the clutch lever that connects and disconnects the hose reel driving force of the winding machine. With this configuration, when the rotation of the hose reel is too high and there is no time to untwist the hose,
You can immediately apply the brake by depressing the lock pedal to stop the rotation of the hose reel, and once the brake is applied, the braking state can be maintained until the next time the clutch lever is turned in the ``on'' direction. This prevents the hose from unraveling during transportation or pest control work.
