With this constitution, fixation of the separator and formation of the passages can be facilitated as well as clogging of the separator can be prevented.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention includes a garbage storage tank mounted on a chassis, and a suction device that suctions and transports the garbage stored in the vessel to the garbage storage tank via a transport pipe. This relates to garbage suction trucks.

(Prior art) Current garbage collection methods have environmental health problems, so
Recently, a garbage collection method using a garbage suction vehicle as described above has been attracting attention. For example, an appropriate number of the above-mentioned vessels are installed in the basement of a high-rise residential building, and the waste generated from each household is stored in the above-mentioned vessel via a chute, and a waste discharge pipe is connected to each of the above-mentioned vessels. The garbage suction vehicle is equipped with a garbage storage tank and a suction device that communicates with it, and a suction pipe is connected to the garbage storage tank. Then, the suction pipe is docked at the tip of the discharge pipe, and the suction device suctions and transports the waste in the vessel to the waste storage tank. The volumetric efficiency of the tank is low.

Therefore, in order to improve this volumetric efficiency, a garbage compression plate is inserted into the garbage storage tank so as to be movable back and forth, and each time a certain amount of garbage is sucked, the garbage compression plate is moved backward to compress the garbage. , it is possible to make it more compact.

(Problem to be Solved) By the way, if the garbage compression plate is not provided, a separator (eg, punched metal for separating garbage and suction air) may be installed near the intersection of the front wall and the upper wall of the garbage storage tank. If the waste compression plate is inserted, the separator cannot be installed near the intersection between the front wall and the top wall of the waste storage tank, and at least the It is necessary to install the separator behind the retraction stop position (front end stop position) of the waste compression plate.However, in this case, the separator must be placed so that it does not get in the way of the movement of the waste compression plate and at a position where clogging is unlikely to occur. Alternatively, a passage for suction air from the waste storage tank to the suction device must also be provided in a position that does not interfere with the suction pipe and within the limited width, height, etc. of the waste suction vehicle. It is necessary to provide

That is, it is very difficult to attach the separator and the passage to the waste storage tank.

(Means for Solving the Problems) The present invention has been made in view of the above-mentioned circumstances, and includes a garbage storage tank mounted on a chassis, and a suction device that transports garbage stored in a vessel through a transport pipe to the garbage storage tank. In a garbage suction vehicle that sucks and transports garbage to a tank, the garbage storage tank is formed with an opening on the rear surface, and is provided with a door that can freely open and close the opening, and a garbage compression plate is installed in the rear of the garbage storage tank. The transport pipe is inserted so as to be compressible and movable toward the waste storage tank, and the transport pipe is connected to the front upper wall of the waste storage tank, and further connected to the upper wall of the waste storage tank near the front end retraction stop position of the waste compression plate. forms a passage along the upper wall that communicates with the suction device, and has a suction end of the passage facing the rear of the waste compression plate at the front end retraction stop position, and the suction end is connected to the waste storage tank. The garbage suction vehicle is characterized in that a separator is attached on substantially the same surface as the upper wall.

(Function) By making the upper wall of the waste storage tank and the separator exist substantially on the same plane, the separator does not get in the way when the waste compression plate is moved, and moreover, the waste attached to the separator is also removed from the waste compression plate. The plate makes it easy to scrape off (and prevents clogging.Also, by forming the passage for the suction air passing through the separator along the upper wall of the waste storage tank, the passage does not get in the way of the suction pipe. Moreover, it fits within the limited width, height, etc. of the garbage suction truck.

Further, a downwardly curved telescopic pipe 12 is inserted into the undulating pipe 8, and can be extended and contracted by a hydraulic cylinder 13. Furthermore, a flexible tube 14 is suspended from the telescopic tube 12, and a tip tube 15 is connected to the lower end thereof. In the retracted position of the suction pipe D2, the distal end pipe 15 is supported by the support member 3C to prevent the flexible pipe 14 and the like from swinging during traveling.

Reference numeral 16 denotes a garbage compression plate (a garbage compression/discharge plate in the embodiment) which is moved back and forth within the garbage storage tank 2 by a hydraulic cylinder 17, and a guide portion 16a is formed in the upper center of the plate to allow the garbage to slide backward. ing. That is, at the frontmost stop position of the garbage compression/discharge plate 16, the guide portion 16a is a suction device connected to the discharge of the swirl tube 5. The suction device F includes a water scrubber 18, a suction blower 19, and a silencer 20.
The pipes 8 to 20e are sequentially formed into pipes 21a to 21g, and the tips thereof are opened upward 21h. Note that the silencer 20b

When the suction blower 19 is activated, it is pushed up by the exhaust pressure and rotated to the open position. There is.

Note that punching metals 23 as separators are attached to the left and right sides of the front upper wall of the garbage storage tank 2, that is, at positions sandwiching the swirl tube 5, and the upper part thereof is formed by a cover 24 as a suction air passage 24&. . Furthermore, a partition plate 25 is attached to the intersection of the front wall and the upper wall of the waste storage tank 2, forming a passage 25B communicating with the double-sided passage 24a. A hole 2e communicating with the passage 25a is provided in the upper part of the front wall of the waste storage tank 2,
A pipe 21a is connected to this hole 2e.

Next, the operation of this embodiment will be explained.

Now, input gates ■l, ■2... are open, and discharge gate E1
, B2... and the inlet valves Vl, V2... are in the closed position, and the garbage thrown in by each household etc. is drained)81.8
2... and is stored in vessels B1, B2...

Therefore, when it is desired to collect the garbage in the vessels B1, B2, etc., the garbage suction vehicle C is first stopped at a predetermined position near the position P where the tip of the discharge pipe D1 is protruded. After that, the suction pipe D2 is rotated, raised and retracted, and the tip pipe 15 is moved to the seventh position.
Dot the tip of the discharge pipe Dl as shown in the figure.

Then, when the suction start switch is turned on, suction transport of the dust to the vessel Bl is started. That is, the input gate E1 is closed, the discharge gate El is opened, and the suction blower 19 is operated to create a negative pressure in the vessel B1, the transport pipe, and the waste storage tank 2. When a constant pressure value is reached, the introduction valve V1 is opened, and subsequently the input gate II is opened. Then, the garbage in the vessel is sucked into the transport pipe while tumbling together with the introduced air, slides down the guide portion 16a, and is sucked and transported toward the rear of the garbage storage tank 2. Moreover, the suction-transported garbage is separated from air by the separator 23 and accumulated in the garbage storage tank 2, and the air is introduced into the water scrubber 18 through the passages 24B and 25a. If the waste in the vessel B1 cannot be sufficiently absorbed by one suction transport, the above-mentioned operation may be repeated. Furthermore, when the suction transport of waste from vessel B1 is completed, the input gate ■1 is opened, the inlet valve ■1 and the discharge gate El are closed, and the suction transport of waste is performed in the order of the next vessels B2, B3, and so on. .

In addition, when a certain amount of garbage is stored in the garbage storage tank 2 during that time, the suction transport is stopped and the garbage compression/discharge plate 16 is moved rearward to the approximate center position of the garbage storage tank 2 by the hydraulic cylinder 17. to compress and compact the waste. At this time, any debris that remains attached to the separator 23 is scraped off by the debris compression/discharge plate 16 and compressed together with other debris. As a result, the volumetric efficiency of the debris storage tank 2 is improved.

Also, when the garbage storage tank 2 is full of garbage, the door 3'? : Rotate upward, open the opening 2a of the waste storage tank 2, and move the waste compression/discharge plate to the rear end position (position shown by the two-dot chain line in Figure 1), and the waste will be discharged to the rear. . Moreover, the garbage pushed into the recess 3a of the door 3 will naturally fall and be released.

(Effects of the Invention) As described above, in this invention, the passage 24a communicating with the suction device F is formed along the upper wall of the garbage storage tank 2 near the front end retraction stop position of the garbage compression/discharge plate 16, and The suction end of 24a faces the rear of the garbage compression/discharge plate 16 at the front end retraction stop position, and the separator 23 attached to the suction end is positioned on a substantially concave surface with the upper wall of the garbage storage tank 2. Therefore, (a) the separator 23 does not get in the way when the garbage compression/discharge plate 16 is moved, and the garbage attached to the separator 23 can be easily scraped off by the garbage compression/discharge plate 16, making it difficult for the separator 23 to become clogged. .

(b) The cover 24 forming the passage 24a does not get in the way of the suction pipe D2, and fits within the limited width, height, etc. of the garbage suction vehicle.
