BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for collecting refuse generated inside a railway vehicle by pneumatic transportation, and more particularly, to an improvement of a refuse input box which is set up on the ground from an air transportation pipe. is there.

[0002]

2. Description of the Related Art As a device for collecting dust generated in a railway vehicle, a device for collecting dust while sucking the dust using air pressure has been proposed.

In this collecting apparatus, as shown in FIGS. 1 and 8, an air transport pipe 3 connected to an air suction device 8 and a garbage storage drum 6 is laid along a railway line 2 or a platform at a vehicle waiting area. The air transport pipe 3 is connected to a garbage input box 9 erected on the ground at a predetermined interval, and the garbage discharged from the entrance and exit of the railway vehicle 1 is input to each input box 9 and the garbage is removed. The air is transported by suction through the air transport pipe 3 and collected in the garbage storage drum 6.

[0004]

The inlet 10 formed in the upper part of the dust input box 9 can be opened and closed by a door 11 in order to prevent the stench of the input dust from leaking outside. . However, conventionally, since the door 11 has a structure that can be opened and closed to the outside, it is opened when dust is input between the vehicles 1 and 1 on the adjacent track 2 as shown in FIG. There has been a problem that the door 11 easily interferes with the vehicle, which also hinders the work of putting dust.

[0005] Further, if a structure is adopted in which trash put in a large number of trash input boxes 9 is directly transported as it is through the air transport pipe 3, dust may be thrown into the air transport pipe 3 beyond its transport capacity, causing clogging. Also, there is a problem that the amount of dust stored in the dust storage drum 6 cannot be properly controlled.

Further, due to the structure in which a large number of dust input boxes 9 are connected to the air transport pipe 3, if there is an air leak at the connection between each input box 9 and the air transport pipe 3, the air transport pipe 3 will be connected to the outside. There is a problem that air enters and the negative pressure inside the transport pipe 3 drops, so that a sufficient trash transport power cannot be obtained.

Therefore, the present invention solves the above-mentioned various problems, and performs the work of charging garbage with good workability and the efficient collection of garbage while maintaining the pneumatic transportation force without air leakage. It is an object of the present invention to provide a collection device that can perform the collection.

[0008]

In order to solve the above-mentioned problems, the refuse collection device of the present invention lays an air transport pipe connected to an air suction device and a refuse storage drum along a railway line or a platform. A garbage input box erected on the ground at a predetermined interval is connected to the air transport pipe, and a door that opens and closes toward the inside of the box is provided at an input port provided at the top of the garbage input box. The drive unit to be rotated is connected, and a dust discharge valve for opening and closing the connection portion is provided at a connection portion between the dust input box and the air transport pipe, and a dust storage chamber is provided inside the input box above the dust discharge valve. The dust discharging valve is formed so as to be slidable in the horizontal direction. A sealing member which is provided with a concave portion on the other side and which is provided with a valve elevating means for moving the roller in the vertical direction by fitting the roller into the concave portion, and which is pressed against the dust discharging valve around the connecting portion by the vertical movement of the dust discharging valve. The structure was adopted to prevent air leakage.

[0009]

In the garbage collecting apparatus having the above-mentioned structure, the door of the input port is turned inside the input box and is not opened outside, so that there is no interference with the railcar and no obstacle to the trash input work. In addition, when the garbage is thrown in, the connecting part is closed with a garbage discharge valve, and the garbage is temporarily stored inside the garbage input box. When the storage room of the input box is full or when the amount of transported refuse in the air transport pipe is small, the refuse discharge valve is opened and the refuse is loaded into the pneumatic transport pipe.

On the other hand, when the dust discharge valve slides to the connecting portion, it moves up and down by the valve elevating means and presses against the seal member, thereby preventing air leakage between the connecting portion and the dust discharging valve.
