Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is suitable for cleaning sidewalk garbage boxes installed in station rotaries, downtown areas, etc., and surrounding sidewalks, etc., and is particularly suitable for cleaning small vehicles equipped with various cleaning devices. The present invention relates to a road garbage collection vehicle constructed of:

[Conventional technology]

Cleaning of garbage bins filled with cigarette butts, paper scraps, etc. and the surrounding sidewalks was generally done by hand.

In order to eliminate such manual cleaning, conventionally, for example, as disclosed in Japanese Patent Application Laid-Open No. 53-89119, a garbage tank (garbage storage box) is pivotally mounted on the chassis so that it can be raised and lowered, and a hinge is attached to the rear of the garbage tank. A packer (tailgate) rotatably connected to the backer, a sealing means for sealing between the garbage tank and the backer, a separator (cyclone) housed in the packer, and a garbage feeder for feeding garbage into the garbage tank. A garbage collection truck equipped with a suction means in which a feeder, a suction hose, a separator, a garbage tank, and a suction device are connected in sequence is also installed in the upper part of the garbage collection box or input section as disclosed in Utility Model Application Publication No. 63-180606. , a vacuum pump, one or more cyclones connected to at least one of the suction port or the discharge port of the pump, and a cleaning device having a solid-dispersion mechanism such as a bag filter W, the discharge portion of the cleaning device having a flexible Various proposals have been made in which vibrators are connected and the open end of the flexible vibrator is suspended below the input section.

[Problem to be solved by the invention]

However, all of the above conventional examples use a cyclone system and are equipped with a suction hose (or flexible vibrator), but this cyclone is installed at the rear of the vehicle or above it, such as inside the tailgate', the garbage storage box, and the top of the tailgate. Not only is this installation disadvantageous in terms of vehicle turning angle, making it unsuitable for small cars, but the length of the suction hose cannot be made very long due to the storage method.

Moreover, since generally collected garbage and suctioned garbage are mixed in the garbage storage box, when cigarette butts and the like are sucked and collected, the incidence of fires and the like increases.

In addition, in Utility Model Application No. 63-180606, since the suction device is installed on the garbage storage box or the tailgate,
Not only does it not look good, but it also requires a means to transport the garbage separated by the cyclone from inside the tailgate to the garbage storage box.

Furthermore, none of the above conventional examples takes any measures to clean the roads surrounding the garbage bins, and therefore, there is still a problem in that cleaning must still be done manually in such places. was there.

In view of the above, it is an object of the present invention to provide a vehicle that matches the aesthetics of the city, and in particular, a small vehicle that is equipped with various types of cleaning equipment so that garbage can be collected and transported efficiently and hygienically. shall be.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

A machine room 3 partitioned by a partition plate 2 is installed at the front of the vehicle body 1 of the road garbage truck, and double doors 4 are provided on both sides of the machine room 3 to open the space. At the rear of the vehicle body 1, a garbage storage box 5 is disposed which protrudes forward at the upper part and covers the upper surface of the machine room 3, and its lower end is supported by the vehicle body 1 via a pivot 6 so as to be dumpable. .

Inside the machine room 3, a suction device 9 for suctioning butts etc. is housed, which is mainly composed of a small prime mover 7 and a vacuum generating blower 8. 10 is attached. Furthermore, this blower 8
is connected via piping 11 to a small storage box 12 partitioned inside the front of the garbage storage box 5, and
A suction hose 14 wound around a hose reel 13 is connected to this small storage box 12 .

Here, the piping 1 between the blower 8 and the small storage box 12 is connected.
1 is provided with a joint part that can be separated from the dump discharge side.

As shown in FIG. 3, the small-sized prime mover 7 includes an electric actuator 15 that switches the rotation speed between two speeds, low and high speed.
A clutch (not shown) is provided that cuts off power transmission to the blower 8 when the small motor 7 is running at low speed, and connects and transmits the power at high speed. Switching is performed by a temperature sensor relay 18 using a temperature sensor 17 disposed within the temperature sensor 12 .

In other words, turn on one engine key switch and turn on the small motor 7.
When driven, the electric actuator 15 is actuated by the current from the current limiter 20, and the small prime mover 7 rotates at a low speed. At this time, the blower 8 is stopped due to the clutch being disconnected. Then, when the blower work switch 16 is turned on, the small electric motor 7 rotates at high speed by switching by releasing the electric actuator 15, and the clutch is connected and the blower 8 rotates.This generates a vacuum and the suction hose 14 is turned on. It becomes possible to suction and collect garbage such as cigarette butts inside the mailbox.

Here, when the embers in the cigarette butt container are sucked in and the inside of the small storage box storage 12 catches fire, the internal temperature sensor 17 detects this and operates the electric actuator 15 to reduce the rotation speed of the small prime mover 7. At the same time, the vacuum generating blower 8 is stopped, and at the same time, a water pump (not shown) is activated to spray water in the fire extinguishing water tank 21 to extinguish the fire. If the temperature sensor 17 is reset after the fire is extinguished, the work can be restarted.

Note that the fire prevention function is activated even when the small motor 7 is stopped during normal operation (5).

In this way, by sucking up cigarette butts, ashes, etc.
It is hygienic by preventing cigarette butts from being blown away by the wind and workers being aroused by odors, and also improves work efficiency and saves labor by removing and suctioning things stuck to the bottom. can be achieved. Furthermore, by operating the blower only during work, it is possible to save energy and reduce noise.

The small storage box 12 is for storing garbage such as cigarette butts and ashes vacuumed by the suction device 9,
A dust filter 22 is provided at the top of the filter 22, and is configured to guide the air that has passed through the filter 22 into the floor 8. At the rear end of the filter 22, a rear opening that communicates with the garbage storage box 5 is opened and closed. A discharge door 23 is provided.

This discharge door 23, as shown in FIGS. 4 and 5,
Its upper end is rotatably supported, and it is disposed at a downward and slightly rearward tilted position, and is further provided with a discharge door locking mechanism 24.

This discharge door lock mechanism 24 prevents the discharge door 23 from being opened by mistake, and also allows the garbage storage box 5, and eventually the small storage box 12, to be dumped (
This is to allow the discharge door 15 to open by its own weight by tilting it (tilt), and the rotary lenoid 25
A connecting rod 26 is rotatably connected to the tip of the rod 25a of the rotary solenoid 25, and the center of the rotary solenoid 25 is rotatably supported via a pin 27a, and the end is rotatably connected to the connecting rod 26. and connect the other end to pin 27b.
It is mainly composed of a lock pin 28 and a bell crank 29 connected to a rotating and sliding white flower via an elongated hole 28a.

As a result, the rotary solenoid 25 is actuated to move the lock pin 28 upward along the guide 30 via the connecting rod 26 of the rod 25a1 and the two bell cranks, thereby causing the lock hole formed in the bracket 31 attached to the discharge floor 23 to move upward. By removing the lock pin 28 from inside 31a,
Without this lock, the lock pin 28 is moved downward in the opposite manner to the above, and the lower end thereof is inserted into the lock hole 31a of the bracket 31, thereby locking the bracket 31.

Here, as shown in FIG. 6, the lock hole 31a has a long structure extending in the vehicle direction, and by positioning the adjustable adjustment plate 32 thereon, the lock hole 31a can be adjusted.
It is possible to make fine adjustments.

Furthermore, a hollow sponge-like gasket 33 for sealing is fixed to the peripheral edge of the inner circumferential surface of the discharge bed 23, which improves the adhesion of the discharge bed 23 when it is closed, and improves the adhesion of the discharge bed 23 during vacuum suction. Designed to prevent air leakage.

The rotary solenoid 25, as shown in FIG.
When the changeover switch 34 is moved from the neutral position to the discharge side and the dump switch 35 is moved from the neutral position to the up or down side, the lock is released and the dump switch 3 is activated.
When the rotary solenoid 5 is set to the neutral position or the diagonal exchange switch 34 is set to the loading side, electricity to the rotary solenoid 25 is cut off, and the rotary solenoid 25 returns to its original position and is locked.

Then, in the cleaning work area, vacuum is generated during suction work, especially inside the small storage box 12, and the gasket 33 of the discharge floor 23 is crushed and the gasket 33 is crushed, so it is necessary to press the discharge floor 23 into close contact with the lock. There isn't.

After the cleaning work is completed, when discharging the garbage in the small storage box 12, press the changeover switch 3 on the operation panel installed in the driver's seat.
4 to the discharge side, the rotary solenoid 25
A current flows through the lock, which activates the lock and releases the lock. In this state, by dumping the garbage storage box 5, the discharge floor 2
3 opens under its own weight and ejects the waste inside.

Note that by making the floor surface of the small storage box 12 slightly upwardly forward, this evacuation performance can be improved, and by making the tip of the lock pin 28 point-shaped as in the illustrated embodiment, This allows it to easily enter the lock hole 31a.

At the rear end of the garbage storage box 5, there is a garbage storage box 5 at the time of dumping.
A rear gate 36 is provided to close an opening that serves as an outlet for discharging dust inside.

As shown in FIG. 8, this rear gate 36 is rotatably supported at its upper end via a hinge 37, and is mounted inside a cylinder cover 38 whose base end is attached to the rear side surface of the garbage storage box 5. The opening is raised and lowered to open and close by the operation of three electric cylinders rotatably connected to the bracket 40, which has the tip of the piston rod 39a attached to the rear gate 36. Here, since the three electric cylinders are arranged in the garbage storage box 5, the piston rod 39a is surrounded and protected by the bellows-type rubber cover 41.
Dust-proof measures are taken.

In this way, the rear gate 36 is raised and lowered by the electric cylinder 39, but a rise completion detection switch 42 and a descent completion detection switch 43 are installed at predetermined locations (not shown) to generate more cylinder thrust (power) than necessary. We are trying not to let that happen.

That is, as shown in FIG. 9, when the changeover switch 34 is set to the discharge side and the rear gate switch 44 is set to the raising or lowering side, the rear gate 36 is raised or lowered by the electric cylinder 39. Then, when the ascent is completed or when the descent is completed, it is detected by the ascent completion detection switch 42 or the descent completion detection switch 43, and the electricity to the three electric cylinders is cut off via the relay switch. .

Furthermore, a hollow sponge-like packing 45 for sealing is fixed to the peripheral end of the inner circumferential surface of the rear gate 36.

As shown in the figure, the vehicle is configured so that dumping can be performed when the body dump safety switch 46 is turned on and the body dump switch 47 is set to the upward side.

By opening and closing the rear gate 36 using the electric cylinder 39 in this manner, the structure is relatively simple and noise generation can be suppressed as much as possible. In addition, since the structure of the electric cylinder 39 is a screw jack type,
The rear gate 36 is supported in the position where the electricity is turned off, thereby eliminating the need for a fall prevention stay, and the electric cylinder 39 itself can fix the rear gate 36, thereby eliminating the need for a locking device for the rear gate. Furthermore, by pulling the rear gate 36 toward the garbage storage box 5 using the electric cylinder 39 and crushing the packing 45,
Leakage of sewage can be reliably prevented.

Further, one side of the garbage storage box 5 is provided with a garbage input opening 48 and four opening/closing doors for opening and closing this opening 48.

As shown in FIGS. 10 and 11, this opening/closing door 49 is rotatably supported at its upper end via a hinge 50, and a bracket 51 whose base end is attached to the garbage storage box 5 can be attached easily. 51a, the tip of the piston rod 52a is rotatably connected to approximately the center of the opening/closing door 49 by gas cylinders 52, which can be flipped up to open and close the opening/closing door 49.

That is, by unlocking the opening/closing door 49 and lifting it upward by hand, the gas cylinder 52 acts as an auxiliary force, allowing it to be opened easily, and the garbage disposal opening 4 can be opened by hand.
8 is ensured.

This gas cylinder 52 is provided with a bellows-type rubber cover 53 to make it dustproof and waterproof, considering the garbage input opening 48 and the outdoors.

In this way, by supporting the opening/closing door 49 by the reaction force of the gas cylinder 52, a fall prevention stay can be made unnecessary.

In addition, similar to the above-mentioned rear gate 36, a hollow sponge-like gasket 54 for sealing is fixed to the peripheral edge of the inner circumferential surface of the four opening/closing doors, and this gasket 54 is deformed when the four opening/closing doors are closed. By doing so, the sealing here is ensured.

Inside the machine room 3, a road surface cleaner unit 55 is housed to clean the area around the garbage post and the sidewalk in a hygienic and efficient manner.

This road surface cleaner unit 55 is shown in FIGS.
As shown in the figure, it is equipped with a pair of swing wheels 56 and a pair of wheels 57 with swing stoppers, with inverted U-shaped push bars 58 and 59 erected at the front and rear, and surrounded by a pair of side covers 60 and a front Surrounded by a cover 61 and a rear cover 62,
Furthermore, a small vacuum cleaner 68 mainly composed of a small generator 65, a vacuum cleaner motor section 66, and a vacuum cleaner tank section 67 is housed inside a cart 64 to which an upper cover 63 is attached.

Here, the front cover 61 is provided with a latch type flat handle 69, which can be opened and closed via a hinge 70, and the upper cover 63 can also be opened and closed via a hinge 71.

A rubber hose 72 is connected to the vacuum cleaner tank section 67, and a brush 7 is attached to the tip of the hose 72.
3 are connected to each other, and furthermore, a pair of auxiliary wheels 74 are provided on the sides of this brush 73. Further, the position of the brush 73 can be adjusted via a knob nut 75.

In this way, the road surface cleaner unit 5 can be loaded and unloaded freely.
5, it is possible to carry out suction and extraction work of garbage on the road surface over a wide range.

The road surface cleaning unit 55 is normally transported while being housed inside the machine room 3 of the garbage truck, and is removed from the garbage truck as needed for use.
A lifter 76 is provided inside for this loading and unloading.

As shown in FIGS. 14 and 15, the lifter 76 is provided with an electric or hydraulic lifter cylinder 77 facing upward, and a sheave 78 is fixed to the upper end of the cylinder 77. A chain 79 with one end fixed is wound around this sheave 78, and the other end is connected to a movable plate 81 via a joint 80, so that the movable plate 81 moves up and down as the lifter cylinder 77 operates. It has been like that.

This movable plate 81 is configured to move vertically up and down using a plurality of rollers 82 as a guide, and at its lower end is a fork 83 on which the road surface cleaning unit 55 is placed.
The fork 83 is connected to the movable plate 81.
It is designed to move up and down in unison with the body.

Furthermore, this lifter 76 is equipped with a lifter lock mechanism 84.

That is, a lock hole 81a is provided at a predetermined position of the movable plate 81.
A lock pin 85 is provided at a position facing the lock hole 81a, the lower end of which is swingably supported, so that the lock pin 85 is locked when inserted into the lock hole 81a. It has been said that

Furthermore, this lock bin 85 is connected to a swing lever 87 via a connecting rod 86, and by swinging this swing lever 87, the lock bin 85 is moved back and forth.

As a result, for example, when unloading the road surface cleaner unit 55 from a garbage truck, the swinging arm 87 is first swung to move the lock bin 85 backward to unlock it, and in this state, the lifter cylinder 77 is moved down to remove the moving plate. 8
1. Further, the fork 83 is lowered to the road surface, and in this state, the road surface cleaner unit 55 placed on the upper surface is lowered. When loading this, the fork 83 is lowered as described above. , by placing the road surface cleaner unit 55 on the upper surface of the fork 83 and operating the lifter cylinder 77 in this state to raise it, the movable plate 81 and eventually the fork 83 are raised, and when it reaches a predetermined position, the lifter cylinder By stopping the operation of the lock pin 77 and swinging the swing lever 87, the lock bin 85 is inserted into the lock hole 81a and locked.

Furthermore, as shown in Figure 16, when this lock is released,
A full-lock detection switch 88 such as a proximity switch is provided to detect the state of the lock, and when the lock is released, this switch 88 is turned on and the warning light 8 is turned on.
The button lights up to confirm that the lifter lock has been released, and this also turns on and lifter switch 9
