That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-3 As shown, in the first embodiment of the utility model, a self-cleaning dust collector for the unloading position of a garbage transfer station includes a shell 1, one end of the shell 1 is provided with an air inlet 2, and the other end is provided with an air outlet 3, and a primary filter 4 and a secondary filter 5 are sequentially arranged in the shell 1 along the air inlet direction, and a cleaning component 6 for cleaning the secondary filter 5 is also arranged inside the shell 1, and the cleaning component 6 includes a cleaning nozzle 61, a nozzle pipe 62 for conveying cleaning liquid to the cleaning nozzle 61, and an external water inlet pipe for providing a water source, and a sewage collection bucket 7 is also provided at the bottom of the shell, and the air inlet 2 is provided with an air suction type air collecting hood 21.

[0030] Furthermore, the matrix of the cleaning nozzles 61 has 16 uniform numbers, and the cleaning radius of the cleaning nozzles 61 is greater than or equal to the distance between adjacent cleaning nozzles 61 , so as to facilitate all-round cleaning of the secondary filter screen 5 .

[0031] Furthermore, the shell 1 is a tubular structure, and its diameter gradually increases from the air inlet 2 to the primary filter 4.

[0032] Furthermore, a wind pressure detector 8 is disposed inside the housing 1 .

[0033] Furthermore, an intelligent controller 9 for controlling the operation of the cleaning component 6 is also provided at the outer end of the housing 1 .
