Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning vehicle accessories, specifically relating to an air intake filter structure for a garbage collection bin of a sweeper truck. Background Technology

[0002] With the development of technology, street sweepers are frequently seen cleaning streets. Current sweepers generally use a sweeping disc to sweep garbage under the vehicle while simultaneously spraying water to suppress dust. A suction device under the vehicle then draws the garbage into a garbage collection bin. A fan creates negative pressure in the bin to achieve the suction function. Therefore, the garbage collection bin and the fan must be connected for suction. To prevent garbage from entering the fan and damaging it, a filter is usually installed at the air intake to block most larger pieces of garbage. However, due to the complex road environment and the variety of garbage types, garbage often sticks to the filter, causing blockages. This reduces the air intake area, lowers the negative pressure in the collection bin, and affects the garbage suction capacity. Therefore, after completing daily sweeping work, operators frequently need to clean the air intake, especially rinsing the filter to ensure it is not clogged. In addition, after prolonged use, large pieces of trash such as stones and broken bricks can damage the filter and require timely replacement. The air intake is usually located on the innermost side of the trash can, which makes cleaning and replacing the filter extremely inconvenient and troublesome.

[0003] In view of the above, it is necessary to design a simple, low-cost air intake filter structure for the garbage collection bin of a sweeper truck that can effectively block garbage and is easy to replace and clean. To this end, the applicant has made a beneficial design, and the technical solution described below arose from this background. Utility Model Content

[0004] The purpose of this invention is to provide an air intake filter structure for the garbage collection bin of a sweeper truck, which helps to improve the air intake structure so that the filter screen can be quickly replaced to block garbage and facilitate cleaning, thereby reducing the labor intensity of operators.

[0005] The present invention accomplishes its objective as follows: a suction port filter structure for a garbage collection bin of a sweeper truck, comprising a vehicle beam, a garbage collection bin mounted on the vehicle beam, and a fan mounted on the vehicle beam and connected to the garbage collection bin. The characteristic feature is that: a suction port is provided at the connection point between the garbage collection bin and the fan; a suction channel is formed around the suction port towards the fan; a downwardly opening suction hood is formed around the suction port towards the garbage collection bin; a detachable filter device is provided at the opening of the suction hood, comprising a fixed frame hinged to the inner wall of the garbage collection bin and a filter screen pressed between the opening of the suction hood and the fixed frame.

[0006] In one specific embodiment of this utility model, the vehicle beam is supported on a horizontal base by wheels.

[0007] In another specific embodiment of this utility model, the air suction channel extends toward the fan side and is obliquely downward and sealed to the fan.

[0008] In another specific embodiment of this utility model, the fan mechanism comprises an exhaust port, an exhaust port, and a fan mounting base. A sealing ring is formed around the opening end of the exhaust port. The air intake channel is connected to the exhaust port and sealed by the sealing ring. The exhaust port is connected to the outside atmosphere. The fan is fixed to the vehicle beam by the fan mounting base.

[0009] In another specific embodiment of this utility model, a hinge seat is fixed to the inner wall of the garbage recycling bin at the position corresponding to the lower edge of the fixed frame. The hinge seat is hinged to the lower edge of the fixed frame by a set of hinges. A fixed seat is fixed to the lower end of the suction hood at the position corresponding to the upper edge of the fixed frame. The upper edge of the fixed frame is folded upward to form a fixed edge. The fixed edge and the fixed seat are fixedly connected by a set of bolts. A filter clearance opening is formed in the middle of the fixed frame. The filter screen is placed at the filter clearance opening and its four edges are pressed between the opening edges of the fixed frame and the suction hood.

[0010] In another specific embodiment of this utility model, the filter screen is a stainless steel wire mesh.

[0011] The present invention has the following advantages after adopting the above structure: Since the structure of forming a suction hood at the air inlet and setting a detachable filter device at the suction hood is adopted, it can not only effectively block garbage from entering the fan, but also quickly replace the filter screen to reduce the difficulty of cleaning. Moreover, the inclined design of the filter screen makes it difficult for garbage to stick and easy to clean, thereby improving the dust removal effect and reducing the workload of the operators.
