The swivel joint 9 includes a main body 91 connected to the cleaning liquid supply source P, and a rotary pipe 90 having one end rotatably fitted to the main body 91, and the other end of the rotary pipe 90 is fitted to the bracket 20. The base end of the pipe member 50 is the lid 2
And is fitted into the bracket 20 and communicates with the rotary pipe 90 through a port 20a in the bracket 20.

This will be described in more detail below.

The bucket 1 is formed so as to have an inlet / outlet 10 on its upper surface side and an outlet passage 11 on its lower surface side, and its planar shape is arbitrary.

The lid 2 is formed to openably and closably cover the entrance / exit 10 of the bucket 1 and has a bracket 20 at one side end thereof, and the bracket 20 is pivoted to a bracket 12 attached to the bucket 1. Then, the lid 2 is freely opened and closed with the pivotal portion as the center of rotation.

The lid 2 is adapted to be opened and closed when the basket 3 described later moves up and down (see FIG. 3).

In the present embodiment, the basket 3 is formed so that its plane shape is circular, and the main body 30 is formed of a wire mesh, and an object to be cleaned (not shown) can be housed inside thereof. It is becoming like this.

The basket 3 is supported on the upper end side of the shaft 31 at the center of the lower surface side thereof, and is formed so as to be horizontally rotatable.

The lower end of the shaft 31 has a horizontal arm member 32 disposed below.
It is said to be planted at the tip of.

The base end of the arm member 32 is connected to the lower end of a vertical rod 33 which is arranged so as to be retractable in the bucket 1.

The upper end of the vertical rod 33 penetrates the upper surface side of the bucket 1 and projects upward to the outside, and is connected to the upper end of a fluid pressure cylinder 4 described later.

A roller 34 is disposed at the base end of the arm member 32, and the roller 34 is adjacent to the inner wall surface of the bucket 1.

A guide rod 35 is erected on the arm member 32, and a roller 36 is held on the upper end of the guide rod 35.

The basket 3 has a plurality of fins 37 in the peripheral portion of the lower surface of the main body 30 thereof.
0, that is, the basket 3 can be horizontally rotated.

The fin 37 is formed in a flat plate shape in the figure, but it may be formed of a curved plate.
The body 30 which is previously formed like a so-called water turbine is used.
You may make it connect with the lower surface of.

The fluid pressure cylinder 4 is formed so as to expand and contract according to the supply and discharge of air or oil, and the upper and lower ends of the cylinder body 40 are connected to the outer wall of the bucket 1 in a bracket.
41, it is fixedly arranged outside the bucket 1.

A rod body 42 protruding and retracting in the cylinder body 40 projects upward, and an upper end of the rod body 42 is connected to an upper end of the vertical rod 33 by a horizontal bracket 43.

Therefore, when the fluid pressure cylinder 4 is extended, the rod body 42 projects from the inside of the cylinder body 40, and the vertical rod 33 rises in synchronization with the projection of the rod body 42.

As the vertical rod 33 rises, the arm member 32
Is raised, and accordingly, the basket 3 is raised.

Also, the raising of the arm member 32 causes the guide rod to
As the guide rod 35 moves upward, the roller 36 at the upper end of the guide rod 35 comes into contact with the lower surface of the lid 2.

When the arm member 32 continues to be raised, the lid body 2 is pushed up by the roller 36, that is, the guide rod 35, so that the base end side of the lid body 2 is pushed up. It will be opened upward with the end side as the center of rotation.

At this time, the upper surface side opening of the bucket 3 is present in the opening 10 of the bucket 1 or in the vicinity thereof.

Further, if the ascending stroke of the basket 3 is reversed to the descending stroke, the lid 2 is closed, and the basket 3 is further lowered and returned to a predetermined position.

That is, in the present invention, the lid body 2 is automatically opened and closed when the basket 3 moves up and down.

Next, the cleaning nozzle 5 is disposed on the lower surface side of the lid body 2 and is formed so as to be able to spray the cleaning liquid from above the basket 3.

The cleaning nozzle 5 is formed by providing a large number of perforations in the pipe member 50.
Is shown to be formed in a straight line in the present embodiment, the point is that the cleaning liquid needs to be formed so that the cleaning liquid can be entirely sprayed on the upper surface of the basket 3, and therefore, Can have any shape such as a square shape, a circular shape, and a spiral shape.

It is assumed that the pipe member 50 constituting the cleaning nozzle 5 is arranged so that its substantially entire length extends along the lower surface of the lid body 2, and the base end thereof penetrates the base end of the lid body 2. However, it is guided inside the bracket 20 on the upper surface side, and is rocked integrally with the lid body 2, that is, when the lid body 2 is opened and closed in synchronization.

The proximal end of the pipe member 50 guided into the bracket 20 is fitted into the bracket 20 by an appropriate means as shown in FIG. 4, and the pipe member 50 is fitted into the port 20a in the bracket 20. It is in communication.

A tip of a rotary pipe 90 of a swivel joint 9 is fitted into the bracket 20, and the fitted end is fixedly connected to the bracket 20 by using a pin 21.

On the other hand, the base end of the rotary pipe 90 is rotatably fitted to the main body 91 fixed to the upper end of the bucket 1.

The so-called sealing property is ensured at the fitted end by the interposition of the O-ring 92.

It is needless to say that the inside of the rotary pipe 90 communicates with the port 20a in the bracket 20.

Therefore, when the end of the lid body 2 is lifted as shown by an arrow U in the figure to open the lid body 2 (see FIG. 3), the rotation fixedly connected to the bracket 20 is performed. The pipe 90 is rotated with respect to the main body 91 while ensuring the sealing property.

That is, the cleaning nozzle 5 integrally provided on the lid 2 can be swung following the opening and closing of the lid 2.

A supply pipe 93 is connected to the main body 91 of the swivel joint 9 by means of a pin 94, and the supply pipe 93 is connected to a supply source P (only reference numeral is shown in the drawing). The cleaning liquid of is introduced.

As shown in FIG. 2, the cleaning nozzle 6 is disposed above the basket 3 so as to spray the cleaning liquid from the so-called lateral direction. In the present embodiment, the bucket 1 is used.
A plurality of baskets are arranged so as to surround the basket 3 therein.

Although not shown, the cleaning liquid ejected from the cleaning nozzle 6 is a cleaning liquid from the supply source P, and a predetermined amount of cleaning liquid is ejected together with the cleaning nozzle 5 when the supply source P is operated. Is formed in.

Further, the cleaning nozzle 7 is arranged below the basket 3 and is formed so as to inject the cleaning liquid onto the lower surface portion of the basket 3.

Considering that the cleaning nozzle 7 prioritizes the cleaning from the so-called upper side in this type of cleaning device, it is intended to deal with the fact that the cleaning residue easily occurs on the left and right sides and the lower side. Therefore, it is preferable to dispose it if possible, and it is not absolutely essential to the establishment of the present invention.

The rotating nozzle 8 is formed so that the injection from the nozzle 8 collides with the fins 37 arranged in the peripheral portion of the lower surface of the basket 3, and the injection amount is outside the bucket 1. It is said that the nozzle 8 is arbitrarily controlled by a regulating valve 80 arranged continuously with the nozzle 8.

Therefore, when the cleaning liquid is sprayed from the rotating nozzle 8, the basket 3 is horizontally rotated, and accordingly, the cleaning liquid is supplied to the horizontally rotated basket 3 from above, laterally and further downward. Will be jetted,
It is possible to clean the objects to be cleaned contained in the basket 3 evenly.

By appropriately controlling the injection amount or injection speed of the cleaning liquid from the cleaning nozzles 5, 6, 7 and the rotation nozzle 8, it is possible to shorten the time required for the cleaning work.

In the embodiment described above, when the basket 3 is rotated horizontally, the cleaning solution is used in the present invention, but instead of this, a fluid pressure motor is used,
Alternatively, it goes without saying that an electric motor may be used.

[Effect of device]

 According to the present invention, the following effects can be obtained.

When the arm member is moved up and down by driving the fluid pressure cylinder, the basket and the lid move up and down at the same time, and while the basket is horizontally rotated, the cleaning liquid is sprayed into the basket through the cleaning nozzle. It is possible to automate parts loading / unloading to cleaning, improving workability and shortening work time.

Since the cleaning liquid is sprayed while rotating the basket, the objects to be cleaned, such as machine parts, can be cleaned uniformly and there is no risk of the cleaning residue.

The lid is hingedly connected via a swivel joint and a bracket, and since this swivel joint also serves as a passage for the cleaning liquid, it is not necessary to separately provide a coupling means for the lid and a passage means for the cleaning liquid. The number of points is small, the structure is compact, and a compact and short washing device can be obtained.

Since the swivel joint and the bracket constitute the passage means for the cleaning liquid, a long passage such as a hose is not required and the pressure resistance against the cleaning liquid is improved.
