Technical Field

The utility model relates to the technical field of sanitation sweeper trucks, in particular to a sanitation sweeper truck and a sweeper truck box body.

Background

The sweeping principle of a common environmental sanitation sweeper is that road garbage or sewage is collected by combining sweeping brush collection, high-pressure cleaning and negative-pressure suction. The negative pressure suction is to drive a high-pressure centrifugal fan by a power device to form negative pressure and airflow at a suction device, so that the road garbage is sucked away from the road after reaching the suspension speed. Then the garbage is filtered out in the sweeper box body and is settled at the bottom of the sweeper box body, and clean airflow can be discharged to the outside of the vehicle through the fan and the tail end exhaust duct.

The sweeper box body comprises a box body and a high-pressure centrifugal fan. The high-pressure centrifugal fan is arranged on the box body, and an air inlet of the high-pressure centrifugal fan is communicated with an air outlet of the box body. The high-pressure centrifugal fan and the box body are two independent components, and the high-pressure centrifugal fan and the box body are fixed into a whole through the locking device, so that the structural size of the box body of the sweeper is large.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, the terms "top", "bottom", "upper", "lower", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention but do not require that the present invention must be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

The utility model discloses a sweeper box body which comprises a box body 1 and a fan 3. The fan 3 comprises a casing 5, the box body 1 comprises a top plate 2, and a ventilation opening is formed in the top plate 2. The fan 3 is arranged on the top plate 2. The bottom of the fan 3 is an open structure. The top plate 2 of the box 1 can close the open structure of the casing 5. In other words, the top plate 2 of the box 1 is the bottom plate of the housing 5, and the box 1 and the housing 5 share a plate. So just can reduce the size of motor sweeper box at the direction of height to make the structure of motor sweeper box compacter, do benefit to whole car overall arrangement. In addition, because the chassis 5 omits a bottom plate, the weight of the chassis 5 becomes light, so that not only can materials be saved, but also the process requirements on the box body 1 can be reduced.

In the prior art, the bottom of the housing 5 has a bottom plate, and the bottom plate is provided with an air inlet. When the fan 3 is assembled on the box 1, the air inlet on the bottom plate of the casing 5 needs to be aligned with the ventilation opening on the top plate 2 of the box 1, and a seal needs to be provided between the bottom plate of the casing 5 and the top plate 2 of the box 1, and the air inlet and the ventilation opening are usually overlapped or inserted. The overlapping of the two faces requires a seal to maintain the seal, and the manner of insertion also requires a seal to maintain the seal. In order to improve the smoothness of the whole air duct as much as possible, the air inlet and the vent are required to be ensured to be accurately aligned and tightly attached, so that the processing difficulty and the processing cost of the shell 5 and the box body 1 are improved. In the utility model, the matching relation between the air inlet and the ventilation opening is completely absent, only the periphery of the casing 5 needs to be ensured to contain the ventilation opening, and the size of the open structure at the bottom of the casing 5 is obviously larger than that of the ventilation opening of the top plate 2, so that the assembly is very easy, and the requirement on the machining precision of the casing 5 and the box body 1 is lower. Therefore, compared with the prior art, the utility model reduces the processing difficulty and the processing cost.

The inner flow of the box body 1 enters the inner cavity of the fan 3 through the ventilation opening after being filtered by the filter screen. In order to smooth the air flow at the vent and improve the air inlet efficiency of the fan 3, the utility model arranges a current collector 9 around the vent at the inner side of the top plate 2. The inner side of the top plate 2 can also be understood as the side of the top plate 2 facing away from the fan 3.

Regarding the connection manner of the case 5 and the case 1: the utility model arranges a connecting plate 4 on the periphery of a machine shell 5, and the connecting plate 4 is connected to the top plate 2 of a box body 1 through a bolt 6. Further, the connecting plate 4 is disposed near the bottom of the cabinet 5 so that the connecting plate 4 can be attached to the top plate 2 of the case 1. The specific structure of the connecting plate 4 may be a circle extending around the circumference of the casing 5, or may be a plurality of arrangements around the circumference of the casing 5. If the power of the fan 3 is large, the connection plate 4 is preferably arranged to extend around the circumference of the casing 5 in a circle to improve the firmness of the connection of the fan 3 with the casing 1. If the weight of the fan 3 is light, it is preferable to provide the connection plate 4 in plural arranged around the circumference of the cabinet 5 to improve the assembling efficiency.

In the prior art, an air inlet on a bottom plate of the casing 5 is fitted into a vent hole on a top plate 2 of the box body 1, and a sealing ring 7 is generally sleeved on a circumferential surface of the air inlet in order to seal a gap between the air inlet and the vent hole. However, the sealing ring 7 only overlaps the periphery of the air inlet, and the stability is poor. The utility model arranges a sealing ring 7 between the connecting plate 4 and the top plate 2 of the box body 1, and the sealing ring 7 is a circle arranged around the periphery of the machine shell 5. Sealing washer 7 is compressed tightly between roof 2 and connecting plate 4 of box 1 to sealing washer 7 still can receive the locking effect of bolt 6 on the connecting plate 4, consequently sealing washer 7 can provide effectual sealed, ensures that fan 3's inlet air channel can not take place to leak gas, thereby improves the efficiency of fan.

The fan 3 is a volute fan 3, and the shell 5 of the fan 3 is a volute shell. The air outlet of the fan 3 is along one side of the casing 5 and blows air substantially along the horizontal direction. The motor for driving the fan 3 is directly provided on the ceiling 2 of the housing 5, thus further reducing the height dimension of the sweeper truck body.

The driving motor 13 and the fan 3 are supported by the top plate 2 of the case 1, and in order to ensure the structural strength of the top plate 2, the present invention provides a reinforcing rib 8 on the inner side of the top plate 2. The inner side of the top plate 2 is the side of the top plate 2 back to the fan 3.

The drive motor 13 is provided on the cabinet 5 of the blower 3, and therefore the cabinet 5 also needs to have sufficient strength to support the drive motor 13. The present invention defines the case 5 to be manufactured by welding. The welding process ensures that the housing 5 has a high structural strength.

The utility model also discloses a sanitation sweeper, which comprises a sweeper box body, particularly, the sweeper box body is any one of the sweeper box bodies, the sweeper box body has the effect, and the sanitation sweeper with the sweeper box body also has the effect, so that the sanitation sweeper is not repeated herein.

The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
