Description

INDUSTRIAL APPLICABILITY The present invention is provided in a dust storage box, a dust input box connected to the dust storage box, and a dust input box, and compresses the dust input from the input port of the dust input box and pushes it toward the dust storage box side. Regarding a garbage truck equipped with a dust loading mechanism, especially regarding its deodorizing measures.

Conventionally, in this type of garbage truck, a deodorizing device that automatically sprays a deodorant according to the movement of a push plate or a rotating plate has been known in order to reduce the odor peculiar to the collected dust. (See, for example, Patent Document 1).

Jitsukaisho 48-10521

However, in the method as in Patent Document 1, when the dust loading mechanism is driven, the pushing plate pushes the dust to which the deodorant is attached into the dust collecting box, so that the dust left in the vicinity of the dust inlet There is a problem that the odor cannot be sufficiently eliminated.

Further, in this method, since the deodorant is sprayed every time the dust is thrown in, the consumption amount is large, and the labor and cost of replenishment become a problem.

The present invention has been made in view of the above points, and an object of the present invention is to effectively deodorize the inside of a dust input box with a consumption of as little deodorant as possible.

In order to achieve the above object, in the present invention, the liquid deodorant is sprayed toward the inner surface of the side wall of the dust input box.

Specifically, in the first invention,
The dust storage box, the dust storage box connected to the dust storage box, and the dust charged from the dust storage box provided in the dust storage box are compressed and pushed into the dust storage box side. The target is a garbage truck equipped with a dust loading mechanism.

And this garbage truck is
A deodorant tank that stores liquid deodorants and
An injection nozzle provided near the inner surface of the side wall of the dust input box and injecting the liquid deodorant toward the inner surface of the side wall.
A supply pipe for supplying the liquid deodorant from the deodorant tank to the injection nozzle is provided.

According to the above configuration, the liquid deodorant is sprayed not on the dust itself but on the inner surface of the side wall of the dust input box, so that the deodorant effect remains even after the dust is pushed into the dust storage box, and at the time of work. It has a high deodorizing effect because it is sprayed on a place where odors are likely to be emitted when driving. Further, by providing the injection nozzle in the vicinity of the inner surface of the side wall, the liquid deodorant can be reliably injected onto the inner surface of the side wall. As a result, the garbage truck of the present invention can prevent the odor from leaking from the inside of the dust input box during traveling. The term "near the inner surface of the side wall" means that the inner surface of the side wall is not too close to the inner surface and is far enough to spray the liquid deodorant.

In the second invention, in the first invention,
The injection nozzle is configured to inject the liquid deodorant toward the inner surface of the side wall in the vicinity of the upper edge of the inlet.

According to the above configuration, by concentrating the region for injecting the liquid deodorant particularly near the upper edge of the inlet, the liquid deodorant falls downward along the inner surface of the side wall due to gravity from that position. Therefore, the deodorant can be attached to a wide range of the inner surface of the side wall. The “near the upper edge of the inlet” means a position appropriately separated from the upper edge of the inlet so that the sprayed liquid deodorant does not immediately come out from the inlet.

In the third invention, in the first or second invention,
The dust input box is provided with a sewage tank for collecting the liquid deodorant sprayed on the inner surface of the side wall of the dust input box.

According to the above configuration, even if a large amount of deodorant is sprayed and the deodorant drips down to the lower end of the inner surface of the side wall, the excess deodorant is left in the sewage hole provided in the bottom plate of the dust input box. Enter the sewage tank from. As a result, it is possible to eliminate the trouble that a large amount of deodorant drips on the ground.

In the fourth invention, in any one of the first to third inventions,
A tailgate that opens and closes the above slot,
An open / close detector that detects when the tailgate is closed,
It is provided with a deodorant supply unit that sends out the liquid deodorant from the deodorant tank in response to the signal of the open / close detection unit.

According to the above configuration, if the liquid deodorant is sprayed only when the tailgate is closed, the consumption amount can be suppressed. In the present invention, since the liquid deodorant is sprayed toward the inner surface of the side wall, the deodorizing effect is maintained even after the dust is stored in the dust storage box, as compared with the case where the liquid deodorant is sprayed directly toward the dust.

In the fifth invention, in any one of the first to fourth inventions,
A tailgate that opens and closes the above slot,
Further equipped with a hopper guide rail that guides the movement of the tailgate,
The injection nozzle is configured to inject the liquid deodorant onto the hopper guide rail as well.

According to the above configuration, the liquid deodorant is sprayed not only on the dust itself but also on the hopper guide rail at the rear of the vehicle body, so even after pushing the dust into the dust storage box, the deodorant effect remains and the work is done. It has a high deodorizing effect because it is sprayed on a place where odors are likely to be emitted when driving. In addition, grease is usually applied to the hopper guide rail for smooth movement of the tailgate, and by mixing this grease with the liquid deodorant, the deodorizing effect can be maintained for as long as possible. That is, when the liquid deodorant is completely volatilized, it cannot generate a scent, but by mixing it with a highly viscous grease, the volatility is reduced while maintaining the scent of the deodorant. The deodorant effect is maintained longer than before. In particular, the liquid deodorant can be applied over the entire hopper guide rail by the engaging portion of the tailgate with the hopper guide rail each time the operator opens and closes the tailgate. As a result, the deodorizing effect of the liquid deodorant can be enhanced without the operator's intention. Further, since the tailgate is normally closed when the garbage truck is traveling, the odor leaking from the inside of the dust input box comes out from the gap between the dust input port peripheral edge and the tailgate. A liquid deodorant is applied to the located hopper guide rail. As a result, the garbage truck of the present invention can prevent odor from leaking from the inside of the dust input box during traveling.

In the sixth invention, in the fifth invention,
The liquid deodorant contains a component that is easily mixed with the grease supplied to the hopper guide rail.

According to the above configuration, when mixed with viscous grease, the deodorant component remains on the hopper guide rail, and the deodorant effect can be easily maintained. The grease is not particularly limited as long as it is an industrial grease having a high viscosity.

In the seventh invention, in any one of the fourth to sixth inventions,
The supply pipe extends in the width direction of the dust input box.
An auxiliary injection nozzle is also provided in the middle of the supply pipe in the width direction, and the auxiliary injection nozzle is configured to spray the liquid deodorant on the inner surface side of the tailgate.

According to the above configuration, the odor inside the dust input box is more effectively deodorized by injecting the liquid deodorant not only on the hopper guide rail but also on the inner surface of the tailgate.

In the eighth invention, in any one of the first to seventh inventions,
The supply pipe extends in the width direction of the dust input box.
An auxiliary injection nozzle is also provided in the middle of the supply pipe in the width direction, and the auxiliary injection nozzle is configured to inject the liquid deodorant toward the dust loading mechanism.

According to the above configuration, the deodorant is injected from the auxiliary injection nozzle provided at the center of the dust input box of the supply pipe toward the moving parts such as the sliding plate and the push plate of the dust loading device. , The scent component of the deodorant can be mixed in a wider range with respect to the odor that is about to come out from the inlet.

In the ninth invention, in any one of the first to eighth inventions,
The deodorant tank is provided on the outer surface of the side wall hidden by the openable side panel of the dust input box.

According to the above configuration, since the deodorant tank is hidden in the openable side panel, the appearance is good, and it is easy to check the remaining amount of the liquid deodorant and replenish it.

As described above, according to the present invention, since the injection nozzle for injecting the liquid deodorant toward the inner surface of the side wall of the dust input box is provided, the deodorant in the dust input box is effectively deodorized with as little consumption as possible. It can be performed.

In the open state of the tailgate 22b shown in FIG. 1B, the tailgate 22b is housed above the dust input port 22a and inside the rear surface portion of the dust input box 22. That is, the tailgate opening / closing mechanism is a so-called inner slide type opening / closing mechanism.

The upper end of the tailgate 22b is supported by the tip of the gate support arm 31, and a proximity sensor as an open / close detection unit that detects that the gate support arm 31 descends and the tailgate 22b closes the dust inlet 22a. 32 is provided on the side wall 22e. Grease is supplied to the hopper guide rail 30 for lubrication. The grease may be supplied manually, or it may be supplied from a plurality of locations if it is injected at one location by a centralized pipe.

As shown by a broken line in FIG. 2, a dust loading mechanism 23 for compressing the dust thrown in from the dust throwing port 22a and pushing it toward the dust storage box 21 is provided inside the dust throwing box 22. ing. The dust loading box 22 is provided with an operation switch 22c for operating the dust loading mechanism 23 adjacent to the dust loading port 22a.

The dust loading mechanism 23 includes a rotary plate 23a for scraping the dust thrown in from the dust inlet 22a toward the dust storage box 21 and a pushing plate 23b for pushing the dust scraped up by the rotary plate 23a into the dust storage box 21. And have. The rotary plate 23a is driven by the hydraulic motor 23c, and the push plate 23b is driven by the swing cylinder 23d.

Then, as shown in FIGS. 1A and 3, the garbage truck 1 is provided with a deodorant tank 33 for storing the liquid deodorant. The deodorant tank 33 is provided on either the left or right side wall 22e, and includes an electric pump 34 as a deodorant supply unit. A first supply pipe 33a made of a vinyl hose or the like extends from the deodorant tank 33. A harness 34a extending to the electric pump 34 may be co-tightened to the first supply pipe 33a. The tip of the first supply pipe 33a penetrates the side wall 22e and extends inward. As shown in FIGS. 3 and 5, a second supply pipe 33b made of a metal tube or the like is fixed to the crossbar 22f connecting the left and right side walls 22e via the bracket 33c. The tip of the first supply pipe 33a is connected to the second supply pipe 33b, so that the liquid deodorant from the deodorant tank 33 is sent. Main injection nozzles 35 for injecting a liquid deodorant toward the hopper guide rail 30 are provided at both left and right ends of the second supply pipe 33b. The tip of the main injection nozzle 35 is directed toward the hopper guide rail 30 as shown in FIGS. 4A and 4B. The injection region A is capable of appropriately injecting a liquid deodorant onto the hopper guide rail 30.

Further, at the center of the left and right of the second supply pipe 33b, an auxiliary injection nozzle 36 for spraying a liquid deodorant on the inner surface side of the tailgate 22b is provided. The tip of the auxiliary injection nozzle 36 faces the inner surface of the closed tailgate 22b (shown in region B in FIGS. 3 and 5).

When the proximity sensor 32 detects that the tailgate 22b is closed, the electric pump 34 is driven in response to the signal, and the liquid deodorant is sent out from the deodorant tank 33. It is desirable that the liquid deodorant contains a component that is easily mixed with the grease supplied to the hopper guide rail 30. Specifically, since the grease is oily, it is desirable that the grease contains a component having an affinity for oil.

As shown in FIG. 2, the dust input box 22 is provided with a sewage tank 25, and the liquid collected in the bottom plate from the sewage hole (not shown) provided in the bottom plate of the dust input box 22 enters the sewage tank 25. It is designed to enter. As a result, the liquid deodorant sprayed into the dust input box 22 and accumulated on the bottom plate can be collected in the sewage tank 25.

As shown in FIGS. 2 and 3, the deodorant tank 33 is provided on the side wall 22e hidden by the openable side panel 22d of the dust input box 22, so that the appearance is good and the remaining amount of the liquid deodorant remains. Confirmation and replenishment are also easy.

Next, the deodorizing operation of the garbage truck 1 according to the present embodiment will be described.

When the garbage truck 1 is traveling, the tailgate 22b is closed as shown in FIG. 1A.

Upon arriving at the collection place, the worker of the garbage truck 1 opens the tailgate 22b and throws the garbage from the garbage truck 22a as shown in FIG. 1B. Then, the operation switch 22c or the like is appropriately operated according to the amount of the dust loaded to drive the dust loading mechanism 23, and the dust is pushed into the dust storage box 21. At this time, unlike Patent Document 1, the liquid deodorant is not sprayed every time the dust loading mechanism 23 is driven.

Then, when the loading operation is completed, the operator closes the tailgate 22b as shown in FIG. 1A. The tailgate 22b is closed by rotating the gate support arm 31, and at this time, the proximity sensor 32 detects that the tailgate 22b is closed.

Then, electric power is supplied from the harness 34a to drive the electric pump 34. As a result, the liquid deodorant in the deodorant tank 33 is supplied to the second supply pipe 33b through the first supply pipe 33a.

Then, the liquid deodorant is injected from the main injection nozzle 35 toward the pair of hopper guide rails 30. Since the hopper guide rail 30 is previously coated with lubricating grease, a part of the liquid deodorant is mixed with the grease.

At the same time, the liquid deodorant is injected from the auxiliary injection nozzle 36 toward the inner surface of the tailgate 22b. As a result, the liquid deodorant material adheres to the inner surface of the tailgate 22b.

In this way, by injecting the liquid deodorant not only on the hopper guide rail 30 but also on the inner surface of the tailgate 22b, the odor inside the dust input box 22 is more effectively deodorized.

Further, since the liquid deodorant is sprayed only when the tailgate 22b is closed, the consumption amount can be suppressed.

In the present embodiment, since the liquid deodorant is sprayed not on the dust itself but on the hopper guide rail 30 at the rear of the vehicle body, the deodorizing effect remains even after the dust is pushed into the dust storage box 21. Further, since it is sprayed onto the hopper guide rail 30 on the periphery of the dust input port 22a, which tends to emit an odor during work or when traveling with the tailgate 22b closed, the deodorizing effect is high.

In addition, grease is usually applied for the smooth movement of the tailgate 22b, and by mixing this grease with the liquid deodorant, the deodorizing effect can be maintained for as long as possible. That is, when the liquid deodorant is completely volatilized, it cannot generate a scent, but when mixed with highly viscous grease, the deodorant component tends to remain on the hopper guide rail 30. The deodorant effect is maintained longer than before by reducing the volatility while maintaining the scent of. Further, since the grease spreads in the hopper guide rail when the roller 24 moves up and down with the opening and closing of the tailgate 22b, the liquid deodorant easily spreads.

Therefore, according to the garbage truck 1 according to the present embodiment, since the main injection nozzle 35 that injects the liquid deodorant toward the hopper guide rail 30 of the dust input box 22 is provided, it is effective with as little consumption as possible. The inside of the dust input box 22 can be deodorized.

(Embodiment 2)
6 to 8 show the garbage truck 101 according to the second embodiment of the present invention, which is different from the first embodiment in that the injection direction is different. In the present embodiment, the same parts as those in FIGS. 1 to 5 are designated by the same reference numerals, and detailed description thereof will be omitted.

Also in this embodiment, as shown in FIGS. 6 and 7, the liquid deodorant is supplied from the deodorant tank 33 to the second supply pipe 133b via the first supply pipe 33a. As shown in FIG. 8, the second supply pipe 133b of the present embodiment is fixed to the crossbar 122f connecting the left and right side walls 22e, and extends in the width direction (left-right direction) of the dust input box 22. Both ends of the second supply pipe 133b extend to the vicinity of the side wall inner surface 122a of the dust input box 22. At each end of the second supply pipe 133b, the same main injection nozzle 135 as in the first embodiment is provided.

Specifically, the pair of main injection nozzles 135 are directed toward the inner surface 122a of the side wall, respectively. In particular, the main injection nozzle 135 is configured to inject a liquid deodorant toward the inner surface 122a of the side wall in the vicinity of the upper edge of the dust input port 22a (region A shown by hatching in FIGS. 6 and 7). '). The number of main injection nozzles 135 is not limited to two, and more may be provided.

Further, in the present embodiment, an auxiliary injection nozzle 136 is also provided in the middle of the second supply pipe 133b in the left-right direction. The auxiliary injection nozzle 136 is configured to inject a liquid deodorant toward the rotating plate 23a, the pushing plate 23b, and the like of the dust loading mechanism 23 (region B'shown in FIGS. 7 and 8).

With the above configuration, also in the present embodiment, when the proximity sensor 32 detects that the tailgate 22b is closed, the electric pump 34 is driven and the liquid deodorant is discharged from the deodorant tank 33. Be sent out.

The liquid deodorant is supplied to the second supply pipe 133b through the first supply pipe 33a, and is ejected from the main injection nozzle 135 and the auxiliary injection nozzle 136 at both ends thereof.

In this way, since the liquid deodorant is sprayed from the main injection nozzle 135 not to the dust itself but to the inner surface 122a of the side wall of the dust input box 22, the deodorizing effect is obtained even after the dust is pushed into the dust storage box 21. As well as remaining, it has a high deodorizing effect because it is sprayed on a place where odor is likely to be emitted during work or running.

Further, by providing the main injection nozzle 135 in the vicinity of the inner surface 122a of the side wall, the liquid deodorant can be reliably injected onto the inner surface 122a of the side wall. As a result, even in the garbage truck 101 of the present embodiment, it is possible to prevent the odor from leaking out from the inside of the garbage truck 22 during traveling.

Further, by concentrating the region A'injecting the liquid deodorant particularly near the upper edge of the dust input port 22a, the liquid deodorant falls downward along the inner surface 122a of the side wall from that position due to gravity. Therefore, the deodorant can be attached to a wide range of the inner surface 122a of the side wall.

Further, the deodorant is sprayed from the auxiliary injection nozzle 136 provided at the center of the dust input box 22 of the second supply pipe 133b toward the moving parts such as the pushing plate 23b and the rotating plate 23a of the dust loading mechanism 23. As a result, the scent component of the deodorant can be mixed in a wider range with respect to the odor that is about to come out from the dust inlet 22a.

Further, even if a large amount of deodorant is sprayed and the deodorant drips down to the lower end of the side wall inner surface 122a, the excess deodorant is sewage from the sewage hole provided in the bottom plate of the dust input box 22. Enter tank 25. As a result, it is possible to eliminate the trouble that a large amount of deodorant drips on the ground.

Further, as shown in the range A'in FIG. 6, the deodorant injected from the main injection nozzle 135 may be adjusted so that a part of the deodorant is adhered to the hopper guide rail 30 of the tailgate 22b. By doing so, the same effect as that of the first embodiment can be obtained.
