Description

Garbage Conveying Mechanism and Street Sweeping Truck having Such Mechanism

The present invention relates to a road sweeper that can clean garbage dumped on roads, parking lots, airfield runways, large playgrounds, and the like. A road sweeper is provided with a transfer mechanism.

The road sweeper of the prior art has adopted a vacuum suction method using a blower to suck the waste into the load. Figure 1 schematically shows a portion of the stack of such a vacuum suction road sweeper. Since the blower 8 requires a large amount of power, a separate auxiliary engine 6 must be used in addition to the main engine.

In the vacuum suction type road sweeper, as can be seen with reference to Fig. 3, the power transmission diagram of which is schematically shown, the main engine 30 operates the cylinders 32 and 33 used for opening and closing the loading compartment outlet 22. The auxiliary engine 31 is used to drive the brush 35 and the blower 34. Therefore, although the conventional vacuum suction type road sweeper can perform the cleaning operation irrespective of driving of the vehicle by using the auxiliary engine, it is necessary to mount the blower 8 and the auxiliary engine 6 so that these devices are limited. It occupies a considerable amount of mounting space, which not only reduces the effective space of the loading box, but also consumes a lot of fuel, costs a lot of manufacturing costs for the cleaning vehicle, and reduces the noise of the auxiliary engine 6 driving the blower 8 and the blower itself during the suction process. There is a problem that a lot of noise occurs.

The present invention is to solve the above problems with the prior art, a garbage transport mechanism for a cleaning vehicle of the method of injecting the collected waste by using a conveyor belt to put into the stacker and a conveyor type road sweeper is installed It aims to provide.

The said object travels by winding on the 1st pulley 26 and the 2nd pulley 27 separated from the said 1st pulley 26 by the predetermined distance, and the said 1st pulley 26 and the 2nd pulley 27. A conveyor belt 210 having a plurality of garbage support members 211 arranged at predetermined intervals along its outer surface as an endless belt, and an inner end of which is an outer end of the support member 211 on the conveyor belt 210. The outlet belt 223 surrounds the conveyor belt 210 so as to be adjacent to the first pulley 26, and has an inlet 223 through which roadbed waste flows, and an outlet connected to the inlet 23 of the loading box 21 near the second pulley 27. A conveyor belt cover 25 having a 224 and supported by a cleaning vehicle by a support means, the first and second being driven by rotation of at least one drive pulley of the first and second pulleys 26, 27. The inlet of the conveyor belt cover 25 is driven by running the conveyor belt 210 wound on the pulleys 26 and 27. Garbage transport mechanism for a cleaning vehicle according to the present invention and the garbage for such a cleaning vehicle, characterized in that the waste introduced into the support 223 is supported on the support member 211 and is raised to be introduced into the loading box 21 through the inlet 23. It is achieved by the road sweeper of the present invention provided with a transfer mechanism.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 illustrates a part of a garbage storage box of a road sweeper provided with a garbage transport mechanism 200 according to the present invention, and includes first and second pulleys 26 and 27, a conveyor belt 210, and a conveyor belt cover 25. The garbage transport mechanism 200 for the cleaning vehicle, etc., the brushes 216 and 217, the stacker 21, and the like are schematically illustrated.

As shown in FIG. 2, the first pulley 26 is spaced apart from the second pulley 27 by a predetermined distance. The first pulley 26 is located near the road surface, the second pulley 27 is located near the inlet of the loading box, and at least one of the first pulley and the second pulley is a driving pulley. The first and second pulleys are elastically supported on the conveyor belt cover 25 by brackets 28 and 29.

The conveyor belt 210 is an endless belt wound around the first and second pulleys 26 and 27 and is provided with a plurality of garbage support members 211 arranged at predetermined intervals along the outer surface. The garbage supporting member 211 is inclined toward the direction of travel of the belt from a plane perpendicular to the outer surface of the conveyor belt 210 so that the garbage can be supported and lifted at the top. Accordingly, the conveyor belt 210 travels over the two pulleys 26 and 27 by the rotation of the driving pulley, and is disposed by the garbage support members 211 spaced apart by a predetermined distance along the outer surface of the conveyor belt. While supporting the garbage flowing into the inlet 223 of the conveyor belt cover 25 from below, it is pulled up sequentially as the conveyor belt 210 travels. The on-site garbage carried on the waste support member 211 is wrapped around the belt 210 and the upper side pulley 26, and the attitude of the support member 211 is reversed. It is fed into the stack 21 through (23).

On the other hand, the conveyor belt cover surrounds the conveyor belt such that the inner surface of the cover 25 is adjacent to the outer end of the support member 211 on the conveyor belt. The first pulley 26 and the second pulley 27 are located near both ends of the conveyor belt cover 25, and the second pulley 26 has an inlet 223 through which the roadbed waste flows in the vicinity of the first pulley 26. It has an outlet 224 connected to the inlet 23 of the loading box in the vicinity of the pulley 27 and is supported by the cleaning vehicle by the supporting means. The conveyor belt cover support means comprises an articulating bracket 222 and / or a shock absorber capable of absorbing the impact by the road surface. The shock absorber may use a hydraulic cylinder (212, 213) or a spring. Between the outlet of the conveyor belt cover and the inlet of the loading box is sealedly connected by a connecting member, which may be, for example, a bellows type connecting member 214 such that the road sweeper is not overwhelmed even when traveling along the uneven road surface. have. The end closer to the road surface of the conveyor belt inlet is provided with a skirt 219 for guiding the incoming waste to the conveyor belt 210, and the end of the conveyor belt cover 25 by the road surface closer to the road surface of the conveyor belt cover 25. There is provided a roller 218 that can be rolled along the road surface to prevent wear.

In addition, the road sweeper according to the present invention is a water tank 215 disposed below the stacking box 21, the watering nozzle connected to the water tank 215 to spray water supplied from the water tank 215 on the road surface 217 may be further provided. As a result, since the cleaning operation is performed while spraying water from the sprinkling nozzle 220, it is possible to prevent dust from scattering during cleaning.

On the other hand, the stacking box 21 of the road sweeper of the present invention, as shown by the dotted line 221 of Figure 2, can be taken off the transport mechanism 200 to take a dump posture, the roadbed garbage accumulated in the stacking box 21 It can be dumped through the outlet 22 of the stacking box (21).

Figure 4 is a schematic view of the power transmission of the conveyor sweeper according to the present invention. The road sweeper according to the present invention, which is configured to transfer roadbed garbage to a loading box using a conveyor type transfer mechanism, has a drive pulley 46, a brush 48, a water pump 47, and an outlet as shown in FIG. Since the opening / closing cylinder 410, the lock cylinder 411, and the dump cylinder 412 are all driven by the main engine 40, they do not consume much power as in the conventional vacuum suction type road sweeper using a blower. It can be seen that there is no need for a separate auxiliary engine to drive the blower as in the prior art vacuum suction road sweeper.

Therefore, the conveyor road sweeper of the present invention does not require a blower, an auxiliary engine, a suction device, a discharge duct, etc. used in a conventional vacuum suction type sweeper by using a conveyor belt, so that the space can be easily used in the production of the sweeper and the parts cost can be reduced. The manufacturing cost can be lowered and the noise and fuel cost problem, which was the biggest problem of the conventional vacuum suction cleaner, can be solved.
