Description

Technical Field

[0001] The utility model relates to the field of special vehicles, in particular to a rear door mechanism of a garbage bin cleaning vehicle. Background Art

[0002] Currently, both urban and rural residents have a large number of trash cans, which often become clogged with dirt on the inner and outer walls. The clogged garbage on the inner walls of the trash cans produces a foul odor, and especially during the hot summer months, it breeds bacteria. Currently, many trash can cleaning vehicles have been introduced to the sanitation machinery market. However, the cleaning devices on these vehicles require sanitation workers to move the trash cans onto the cleaning devices for cleaning, resulting in low cleaning efficiency.

[0003] The invention with Chinese patent authorization announcement number CN 113020181B and authorization announcement date June 14, 2022 discloses a trash can cleaning device and a trash can cleaning vehicle. A trash can outer wall cleaning mechanism, a trash can clamping and flipping mechanism, and a control mechanism are installed on the device frame. The trash can clamping and flipping mechanism is located on one side of the trash can outer wall cleaning mechanism. The control mechanism controls the trash can clamping and flipping mechanism to clamp and flip the trash can with the mouth facing upward to the cleaning area in the device frame, and makes the mouth of the trash can face downward, and the outer wall of the trash can is cleaned by the trash can outer wall cleaning mechanism.

[0004] The device operates automatically throughout the cleaning process, eliminating the need for sanitation workers to operate it, resulting in high cleaning efficiency. However, in actual use, it was discovered that the rear door of the device is a single panel. Before loading the trash can, the entire panel needs to be completely flipped over. This requires leaving about 2 meters of open space behind the vehicle when parking. However, many trash cans in cities are not placed in spacious areas, so the trash can needs to be dragged a distance before cleaning, which greatly reduces cleaning efficiency. Summary of the Invention

[0005] The purpose of the utility model is to overcome the defects and shortcomings of the existing technology and provide a rear door mechanism of a garbage bin cleaning vehicle which has a simple structure, is easy to operate and can effectively improve the cleaning efficiency.

[0006] To achieve the above objectives, the technical solution of the present invention is: a rear door mechanism for a garbage bin cleaning vehicle, characterized in that it includes an upper door and a lower door installed on the rear door frame, the upper door is rotatably connected to the top of the rear door frame, the lower door can be flipped and connected to the bottom of the rear door frame through a lower door flip mechanism, and a garbage bin placement rack is vertically installed on the inner wall of the lower door.

[0007] The lower door flipping mechanism includes a flip shaft and a chain transmission mechanism. The sprocket of the chain transmission mechanism is located on the rear door frame. Both ends of the flip shaft are respectively connected to the sprockets. The lower door is sleeved on the flip shaft.

[0008] The trash can placement rack comprises a trash can fixing rack and a trash can lifting rack.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] 1. The utility model separates the rear door into an upper door and a lower door, and installs the trash can placement rack on the inner wall of the lower door. When working, the upper door flips upward and the lower door flips downward. This not only greatly reduces the space required for the rear door, but also greatly increases the door opening speed, thereby improving the cleaning efficiency.

[0011] 2. The utility model adopts a chain transmission mechanism to flip the lower door. The transmission mechanism of the purely mechanical structure has a low failure rate and a high transmission ratio. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural diagram of the present utility model.

[0013] In the figure: rear door frame 1, upper door 2, lower door 3, lower door turning mechanism 4, trash can placement rack 5, turning shaft 6, chain transmission mechanism 7, trash can fixing rack 8, trash can lifting rack 9. DETAILED DESCRIPTION

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0015] See also Figure 1 A rear door mechanism for a trash can cleaning vehicle includes an upper door 2 and a lower door 3 mounted on a rear door frame 1. The upper door 2 is rotatably connected to the top of the rear door frame 1. The upper door 2 is controlled to flip up and down by a cylinder mounted on the roof of the vehicle. The lower door 3 is flipably connected to the bottom of the rear door frame 1 via a lower door flipping mechanism 4. A trash can rack 5 is vertically mounted on the inner wall of the lower door 3. The rack 5 includes a trash can fixing frame 8 and a trash can lifting frame 9. The lower door flipping mechanism 4 includes a flip shaft 6 and a chain drive mechanism 7. The sprocket of the chain drive mechanism 7 is located on the rear door frame 1 (enclosed in the housing). The two ends of the flip shaft 6 respectively pass through the center hole of the sprocket. The lower door 3 is sleeved on the flip shaft 6.

[0016] When the utility model is working, the cylinder rod of the oil cylinder installed on the top of the carriage is contracted, controlling the upper door 2 to flip upward, and at the same time the chain transmission mechanism 7 is started, and the sprocket drives the flip shaft 6 to rotate clockwise, thereby driving the lower door to flip downward. When the upper door 2 and the lower door 3 are flipped into place, the trash can to be cleaned is placed on the trash can lifting frame 9, and the trash can lifting frame 9 lifts the trash can to the trash can fixing frame 8 and fixes it, and then the oil cylinder and the chain transmission mechanism 7 are operated in reverse to close the upper door 2 and the lower door 3 to clean the trash can.
