Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is to collect waste collected in a waste storage tank provided in a high-rise house or the like into a waste storage tank of a waste suction vehicle via a transportation pipe by a suction device. The present invention relates to a garbage suction truck for sucking.

(Prior art) Conventionally, waste generated from high-rise houses, etc. is dropped through a chute into a waste room on the basement floor or the first floor, and the waste is compressed and packed in a container and placed on a truck, which is then incinerated. A method of transporting the waste to a waste storage container or a method of loading the waste storage container on the ground and transporting the waste storage container by truck depending on the time is adopted. However, the conventional method is limited in terms of beautifying the town and improving hygiene.

So, the waste is once stored in the waste storage tank installed underground,
A method of sucking this dust by a vacuum suction device and transporting it to a dust storage tank of a truck by pipe is being considered.

(Problems to be Solved by the Invention) Therefore, the appearance of a dust suction vehicle using the above-described suction device is desired.

According to the present invention, a garbage suction car equipped with a waste storage tank is stopped near the discharge pipe of the waste storage tank, a waste suction pipe connected to the waste storage tank is operated, and the waste suction pipe is connected to the discharge pipe. , Of course, it is possible to suck the waste of the waste storage tank into the waste storage tank by the suction device, but if you stop the waste suction truck near the discharge pipe, you can operate the dust suction pipe, The object is to provide a dust suction wheel having a large working radius of the dust suction pipe so that the above can be easily connected to the discharge pipe.

(Means and Actions for Solving the Problem) The waste suction vehicle of the present invention is provided with a waste discharge port at the rear portion and a waste storage tank having a door for opening and closing the discharge port. A dust suction pipe is connected to the dust storage tank.The dust suction pipe vertically supports a swirl pipe on the upper surface of the front end center of the dust storage tank farthest from the dust discharge port. The undulating tube is horizontally supported by the swivel tube via the first flexible tube, and further, a downward bending tube is inserted into and retracted from the undulating tube, and further, the bending tube is laid through the second flexible tube. The connecting pipe for connection is connected.

In the general traveling state, the dust suction pipe is stored from the upper surface to the rear surface of the dust storage tank. Further, at the time of sucking dust, the connection pipe for connection is extended to the side of the dust suction wheel, is connected to the discharge pipe of the dust storage tank, and sucks the dust in the dust storage tank to the dust storage tank by the suction device.

(Example) T ₁ and T ₂ are waste storage tanks provided on the basement floor of the high-rise house B, and are connected to the lower part of the chute S. Downstream of each of the garbage storage tanks T ₁ and T ₂ is projected H to a specific point A (on the side of the road) on the ground via the on-off valves V ₁ and V ₂ and the underground transportation pipe P. The protruding tube H is normally closed with a manhole. V ₃ and V ₄ are opening / closing valves of the chute S connected to the upstream side of the respective garbage storage tanks T ₁ and T ₂ . V ₅ and V ₆ are open / close valves for air introduction pipes to the waste storage tanks T ₁ and T ₂ .

Reference numeral 1 denotes a chassis of a refuse suction vehicle, and a chassis 1 is equipped with a refuse storage tank 2. The rear portion of the dust storage tank 2 is opened as a dust discharge port 2a, and the dust discharge port 2a is opened and closed by an opening / closing door 3 having an upper portion supported by a horizontal shaft 3a. Four
Is a telescopic actuator for opening and closing the opening and closing door 3. The lower part of the rear end of the dust storage tank 2 is horizontally supported by the chassis 1 and can be tilted backward by the telescopic actuator 5. In this embodiment, the means for tilting the dust storage tank 2 rearward also serves as the means for compressing the dust in the waste storage tank 2 rearward.

The VA is a suction device mounted on the chassis 1 between the operator's cab 1a of the waste suction truck and the waste storage tank 2. Although not shown, the suction device VA is configured by connecting a known water task scrubber, a roots blower, and a silencer sequentially from the upstream side. The roots blower is driven by using the power of the vehicle running engine. Further, the air intake end opening of the water scrubber is opened upward. Then, this upward air suction end opening is automatically connected to the air discharge end opening 6 provided downward on the front upper surface of the dust storage tank 2 when the dust storage tank 2 is not tilted,
Further, it is configured to be in a disconnected state when tilted.

PA is a dust suction pipe connected to the dust storage tank 2. That is, the base end pipe is vertically swiveled as a swivel pipe 11 on the upper surface of the waste container 2 at the center of the front end. The swirl tube 11 is mounted on the sprocket 12a mounted on the swirl tube 11 coaxially with the shaft 11a, the chain 12b wound around the sprocket, and the upper surface of the dust storage tank 2,
The chain 12b is forcibly swung by a drive device 12 including two telescopic actuators 12c that grasp both ends of the chain 12b.
The undulating pipe 1 is provided at the tip of the swirling pipe 11 via the first flexible pipe 13.
4 is a horizontal shaft support 14a. That is, the tip end of the member 11b protruding from the swivel pipe 11 and the tip end of the member 14b protruding from the undulating pipe 14 are axially supported by 14a, and the extensible actuator 15 provided between the both members 11b and 14b undulates the undulating pipe. 14 is forced ups and downs. The undulating pipe 14 is
In the laid-down state, an intermediate portion thereof is designed to be supported by a support stand 16 which is erected on the upper surface of the dust storage tank 2. A bending tube 17 is inserted at the tip of the undulating tube 14,
The tip of the bending tube 17 is bent downward. The bending tube 17 is forcibly retracted and retracted by the telescopic actuator 18. A connecting pipe 20 for connection is connected to the distal end of the bending pipe 17 via a second flexible pipe 19. Three claws 21 are rotatably supported by a tangential axis on the circumference of the connecting connection pipe 20 at equal intervals on the circumference thereof, and are forcedly rotated by a telescopic actuator 22. These nails 21
Can connect and secure the connection pipe 20 for connection with the discharge pipe H of the transport pipe P. The connection pipe 20 for connection is the dust suction pipe PA.
In the storage state, the support member 23 is provided so as to project from the lower portion of the rear end of the dust storage tank 2 (the lower portion of the opening / closing door 3 in the embodiment). That is, a mountain-shaped convex portion 23a is formed at the center of the upper surface of the support member 23, and the convex portion 23a is formed.
It is fixed by inserting the connecting pipe 20 for connection into.

The operation of sucking the dust dumped in the chute S of the high-rise house B and accumulated in the dust storage tanks T ₁ and T ₂ into the dust storage tank 2 will be described below.

First, the operator stops the dust suction wheel in the solid line state (general running state) shown in FIGS. 1 and 2 at a predetermined position near the special place A as shown in FIG. Then, the expansion / contraction actuator 15 is extended to raise the undulating tube 14. At this time, since the convex portion 23a is mountain-shaped, the connecting pipe 20 for connection is pulled out from the support member 23 without coming into contact with the convex portion 23a. After that, the expansion / contraction actuator 18 is extended to project the bending tube 17 rearward. That is, the dust suction pipe PA is in the state shown by the dashed line in FIG. Next, the swivel tube 11 is driven by the drive device 12.
Is appropriately swung to project the second flexible tube 19 and the connecting tube 20 for connection to the side of the dust suction wheel, and the bending tube 17 is retracted and retracted by the expansion / contraction actuator 18, and the undulation tube 14 is undulated by the expansion / contraction actuator 15. By doing so, the connection pipe 20 for connection is docked with the discharge pipe H of the transport pipe P.

Then, the dust container 2 and the dust suction pipe PA are made to have a negative pressure by the suction device VA, the manhole of the discharge pipe H is adsorbed, the manhole is moved to a predetermined position as appropriate, and the negative pressure is released.

After that, the connecting pipe 20 is docked again to the opened discharge pipe H, and further, the expansion / contraction actuator 22 is contracted to rotate all the pawls 21 inward to fix the connecting pipe 20 to the discharge pipe H. .

Then, for example, when it is desired to suck the waste in the waste storage tank T ₁ , the on-off valves V ₂ , V ₃ , V ₅ and V ₆ are closed and the on-off valve V ₁ is closed.
To open. Further, the suction device VA is operated to substantially vacuum the dust storage tank T ₁ , the transport pipe P, the dust suction pipe PA, and the dust storage tank 2. After that, when the opening / closing valve V ₅ of the air introduction pipe is opened, the waste in the waste storage tank T ₁ is sucked into the waste storage tank 2. If it is not possible to suck all the dust with one suction, the above operation may be repeated.

When sucking the waste in the waste storage tank T ₂ , the on-off valves V ₁ , V ₄ , V ₅ and V ₆ are closed and the on-off valve V ₂ is opened.
By operating the suction device VA, the dust storage tank T ₂ , the transport pipe P, the dust suction pipe PA, and the dust storage tank 2 are substantially evacuated. Then, the open / close valve V ₆ of the air introduction pipe may be opened.

Note that the dust sucked from the dust suction pipe PA easily accumulates on the front part of the dust storage tank 2, so after the dust suction work is completed,
The dust suction pipe PA is returned to the state shown by the solid lines in FIGS. 1 and 2, and the expansion / contraction actuator 5 is extended to tilt the dust storage tank 2 rearward to compress the dust in the dust storage tank 2 rearward. As a result, the waste is evenly stored in the waste storage tank 2.

When discharging the sucked dust, as shown in Fig. 3,
The dust suction pipe PA may be swung to the side, the opening / closing door 3 may be opened, and the dust storage tank 2 may be tilted rearward.

(Effects of the Invention) As described above, according to the present invention, the dust suction pipe PA is the swivel pipe 11 having the vertical shaft 11a on the upper surface of the center of the front end of the waste container 2, and the horizontal shaft 14a with respect to the swirl pipe 11. Since the undulating pipe 14, the undulating pipe 14, and the bending pipe 17 protruding and retracting with respect to the undulating pipe 14 are included, if the dust suction wheel is stopped in the vicinity of the discharge pipe H, the connecting pipe 20 for connecting is connected to the vertical axis. 11a, around the horizontal shaft 14a, and at right angles to the horizontal shaft 14a, the connection pipe 20 for connection can be easily connected to the discharge pipe H without moving the dust suction wheel back and forth. Moreover, since the length of the dust suction pipe PA in the horizontal direction is sufficiently long, its working radius is large, and there is no problem even if the precision of the stop position of the dust suction truck is slightly poor.
