Description

Technical Field

[0001] The utility model relates to the technical field of sanitation vehicles, in particular to a garbage overflow prevention device for sanitation vehicles. Background Art

[0002] Garbage collection and transfer vehicles are a type of sanitation vehicle, responsible for transporting various types of garbage generated in urban life from the source to the garbage treatment center or transfer station. Some existing garbage collection and transfer vehicles are equipped with a garbage transport carriage for transporting garbage at the rear, and an openable rear compartment door is provided at the rear of the garbage transport carriage, which is used to dump garbage after opening.

[0003] When this type of garbage collection and transfer vehicle is transporting some wet garbage (such as kitchen waste, etc.), since the rear door is often unable to completely and tightly close with the rear end of the garbage loading compartment, a certain gap is likely to exist between the two. The water content in the wet garbage is relatively high, and the water (liquid garbage) contained in the wet garbage is also part of the garbage. It is easy for it to overflow from the gap between the garbage loading compartment and the rear door and flow to the ground during transportation. Since the flowing water often contains a large amount of corrupt substances and has a strong odor, it is easy to cause certain pollution to the area along the way where the garbage collection and transfer vehicle passes. Summary of the invention

[0004] The utility model aims to solve the deficiencies in the prior art and provide a garbage overflow prevention device for a sanitation vehicle.

[0005] The purpose of the utility model is achieved through the following technical scheme: a garbage overflow prevention device for a sanitation vehicle, comprising a garbage loading compartment, a liquid storage tank, and a conduit, wherein the tail of the garbage loading compartment is connected to a rear compartment door, a collecting box is provided at one end of the bottom of the garbage loading compartment close to the rear compartment door, a translation drive mechanism is provided between the collecting box and the garbage loading compartment, and the collecting box is driven to move along the length direction of the garbage loading compartment by the translation drive mechanism; one end of the conduit is connected to the liquid storage tank, and the other end of the conduit extends into the collecting box, and a liquid pump is provided on the conduit.

[0006] In the utility model, after the garbage transporting carriage is loaded with garbage, the garbage transporting carriage is in a loading state, at which time the garbage transporting carriage is in a horizontal state, and the collection box is driven to be in a forward extension state by a translation driving mechanism. When the collection box is in the forward extension state, the gap between the rear door and the rear of the garbage transporting carriage is located directly above the collection box, so that when the moisture (liquid garbage) in the wet garbage overflows from the gap, the moisture will just flow into the collection box below, and the moisture (liquid garbage) will be pumped into the liquid storage tank for storage by means of a liquid pump and a conduit, thereby preventing the moisture (liquid garbage) in the wet garbage from directly falling onto the driving ground during the driving of the sanitation vehicle and causing pollution to the area along the way. In addition, some fine solid garbage (such as food residues, etc.) may also overflow from the gap, and the overflowed solid garbage will also fall into the collection box below, thereby preventing it from falling directly onto the road surface. When the garbage loading compartment is in the dumping state, the rear compartment door is in the open state, and the garbage loaded in the garbage loading compartment will be dumped outward from the tail of the garbage loading compartment; before the garbage loading compartment is in the dumping state, the collection box is driven by the translation drive mechanism to move to the retracted state, at which time the collection box is completely located under the garbage loading compartment, and the collection box does not extend out of the tail of the garbage loading compartment, thus avoiding the collection box from affecting the dumping of the garbage.

[0007] Preferably, the translation drive mechanism includes an electric cylinder, a guide sleeve, and a guide rod. The guide rod is arranged at both ends of the collection box, one end of the guide rod is fixedly connected to the collection box, the guide sleeve is fixed to the bottom of the garbage loading compartment and is arranged corresponding to the guide rod, and the guide rod passes through the guide sleeve; the electric cylinder is fixed to the bottom of the garbage loading compartment, and the telescopic rod on the electric cylinder is connected to the collection box.

[0008] Preferably, the guide rod is parallel to the length direction of the garbage loading compartment.

[0009] Preferably, a liquid level sensor is provided on the inner wall of the collection box. The liquid level sensor and the liquid pump are both connected to the on-board control device on the sanitation vehicle. When the liquid level in the collection box reaches the height of the liquid level sensor, the liquid level sensor is triggered, and the control device controls the liquid pump to start, and the liquid pump draws the liquid in the collection box into the liquid storage tank. The liquid pump stops running after a fixed time; when the liquid level sensor is triggered next time, the liquid pump runs again.

[0010] Preferably, the liquid level sensor is arranged at a position at half the height of the collecting box.

[0011] Preferably, the width of the collection box is greater than the width of the garbage transport compartment.

[0012] Preferably, the liquid storage tank and the liquid pump are fixed on the outer side of the garbage transport compartment.

[0013] Preferably, the upper end of the rear compartment door is hinged to the upper end of the rear portion of the garbage loading compartment.

[0014] Preferably, a fixing buckle for fixing the conduit is provided on the outer side surface of the garbage loading compartment.

[0015] The beneficial effect of the utility model is as follows: in the utility model, when the garbage transport compartment is in a loading state, the collection box is driven to be in a forward state by a translation drive mechanism, and when the collection box is in the forward state, the gap between the rear compartment door and the rear part of the garbage transport compartment is located directly above the collection box, so that when moisture (liquid garbage) in the wet garbage overflows from the gap, the moisture will just flow into the collection box below, and with the help of a liquid pump and a conduit, the moisture (liquid garbage) will be pumped into a liquid storage tank for storage, thereby preventing the moisture (liquid garbage) in the wet garbage from directly falling onto the driving ground during the driving of the sanitation vehicle and causing pollution to the area along the way.
