Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to an opening / closing device for a dust input port in which an operating lever of a rotary drum for opening / closing the dust input port can be easily rotated.

[Prior Art] Generally, in a high-rise house, etc., each floor is provided with a dust inlet for throwing in the dust discharged from the home,
The dust input port is provided with a dust input / output opening / closing device that opens and closes the input port and limits the size of the input dust.

As shown in FIG. 4 and FIG. 5, the conventional dust inlet opening / closing device is provided with a rotary drum 2 which opens and closes the dust inlet 1 and temporarily stores the introduced dust.
The rotating drum 2 is provided with an operating lever 3 for rotating the rotating drum 2. The rotary drum 2 has a dust receiving port 4 formed in its body, and the loading port 1 is opened by aligning the dust receiving port 4 with the position of the dust loading port 1.
The size of the thrown-in dust is limited by temporarily storing the thrown-in dust in the drum 2. When the rotary drum 2 is reversed by the operation lever 3, the dust throw-in port 1 is opened. It is adapted to be closed and to be thrown into the lower waste collection container (not shown) from the waste receiving port 4.

[Problems to be Solved by the Invention] By the way, in the above-described device, as shown in FIG. 5, a gear group 5 is provided between the operation lever 3 and the rotary drum 2, and the operation lever 3 is rotated by 90 degrees. When rotating the drum 2
Is turned 180 degrees.

However, in the above device, since the gear group 5 is provided in the transmission means of the rotational force, the weight of the entire device becomes heavy, and since the operation lever 3 is manually operated, during the operation, There is a problem that the operability deteriorates due to the frictional resistance of the gear group 5. Especially, when a general woman operates, there is a problem that it cannot be operated easily.

The present invention was created to solve the above-mentioned problems, and an object thereof is to provide an apparatus for opening and closing a dust entrance that can reduce the weight of the entire apparatus and facilitate manual operation of a rotating drum. There is.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides
In the opening and closing device for the dust input port that has a rotary drum that temporarily blocks the dust input port and receives the dust that has been input, rotate the rotary drum so that the rear end is on both sides behind the rotary pin of the rotary drum. An operating lever is rotatably provided by a moving pin, and the distal ends of the operating levers are connected by a handle, and an elongated hole is provided at the center of each operating lever.
One end of the crank lever is connected to the rotary pins on both sides of the rotary drum, the other end of each crank lever is slidably engaged with the elongated hole, and the operation lever rotates in a rotation range of about 60 degrees. The length and position of the crank lever and the slot are set so that the drum can rotate 180 degrees.

[Operation] When throwing in dust, operate the operating lever to open the throwing port, throw dust into the rotary drum from the opened throwing port, and then operate the operating lever again to reverse the rotary drum. Then, the garbage inlet may be closed.

When rotating the rotary drum, the operation of the operation lever is transmitted to the rotary drum via the crank lever, so the operation of the operation lever can invert the rotary drum at a small operation angle. Since no gear group is used, it can be operated easily by manual operation, and the overall weight of the device can be reduced.

[Embodiment] An embodiment of the present invention will be described with reference to the accompanying drawings.

FIGS. 1 and 2 show an embodiment of the dust input port of the present invention, and FIG. 3 shows an example of a dust collection system in which the present invention is adopted.

In FIG. 3, reference numeral 6 denotes a building as a high-rise house, and each layer of the building 6 is provided with a garbage throwing facility 7, and the garbage throwing facility 7 has a container 8 for storing thrown refuse. Is provided. The storage container 8 is transported to the waste storage / discharge facility 10 by the transfer facility 9, and the waste in the container 8 is temporarily stored in the waste storage / discharge facility 10 and then carried out to the outside by the waste collection vehicle 11. There is.

The dust throwing equipment 7 is provided with an opening / closing device 12 for opening and closing the dust throwing port.

The opening / closing device 12 is, as shown in FIGS. 1 and 2,
A waste input port 1 is formed in the main body 13 of the waste input facility 7,
A rotary drum 2 for opening and closing the charging port 1 is rotatably provided at the dust charging port 1.

As shown in the drawing, the rotary drum 2 has a dust receiving port 4 formed in its body, and by opening the throwing port 1 by aligning the dust receiving port 4 with the position of the dust throwing port 1,
The thrown dust is temporarily stored in the rotary drum 2, and when turned over, the throwing port 1 is closed and the dust is thrown into the storage container 8 below.

An operating lever 14 for rotating the rotary drum 2 is provided on both sides of the main body 13 with the rotary pin 2 interposed therebetween.
It is rotatably provided via 15 and both operation levers 14
The tip ends of are connected by a handle 16, and a long hole 17 is formed in the middle of both operation levers 14.

One end of a crank lever 19 is rotatably connected to a central rotary shaft on both ends of the rotary drum 2 via a rotary pin 18, and the other end of the crank lever 19 is connected via a crank pin 20. Is slidably engaged with the elongated hole 17.

In the present embodiment, the crank lever 19 has a length such that the crank pin 20 is allowed to move in the elongated hole 17 and is rotated 180 degrees when the operation lever 14 is rotated approximately 60 degrees as shown in the figure. The rotary drum 2 that rotates integrally with the rotation of the crank lever 19 is configured to be inverted by 180 degrees.

Next, the operation of the above embodiment will be described.

When throwing in dust, first, in order to open the dust throwing port 1 which is closed as shown in FIG.
After manually rotating from the position indicated by the solid line to the position indicated by the chain line in the figure, the rotary drum 2 is inverted, the dust receiving port 4 is aligned with the dust input port 1, and then the dust is thrown into the rotary drum 2. After throwing in the dust, the operation lever 14 is again rotated to the original position, the rotating drum 2 is reversed, and the throwing port 1 is closed. At this time, dust in the rotary drum 2 is discharged downward from the dust receiving port 4 and put into the storage container 8. Further, when the storage container 8 is full, as shown in FIG. 3, the storage container 8 is transported by the transfer facility 9 and the waste is stored in the waste storage / discharge facility 10. After that, the garbage truck 11 appropriately transports the vehicle to the outside.

When opening and closing the opening and closing device 12, the operation of the operating lever 14
Since it is transmitted to the rotary drum 2 via the crank lever 19, the operation of the operation lever 14 is performed at a small operation angle (rotation angle).
Since the rotating drum 2 can be reversed by using, and the gear group is not used unlike the conventional case, the operation of the operation lever 14 becomes light, and good operability that can be easily operated manually is obtained.
The weight of the entire device can be reduced.

In the present embodiment, the example in which the rotary drum 2 can be inverted 180 degrees with respect to the operation angle of the operation lever 14 of approximately 60 degrees has been shown. It can be appropriately selected.

[Advantage of the Invention] According to the present invention, since the operation of the operation lever is transmitted to the rotary drum via the crank lever, the rotary drum can be reversed at a small operation angle. Since it does not use, the operation of the operation lever is light, and good operability that can be easily operated manually is obtained.
It has excellent effects such as weight reduction of the entire device.
