A plurality of fan blades 3 are fixedly connected to the turntable 2. Crushing devices for crushing sundries are respectively arranged on the plurality of fan blades 3. A driving device for driving the turntable 2 to rotate is arranged on the housing 1. In the embodiment of the present application, an air inlet is arranged at the center of the housing 1, and a pipeline can be connected to the air inlet, so as to facilitate directly adsorbing sundries such as fallen leaves on the ground; an air outlet is arranged on one side of the crushing device, and the air outlet can communicate with the trash can of a garbage collection vehicle, which is convenient for subsequent centralized treatment of the absorbed impurities.

[0023] Referring to Figure 1 and Figure 2 , in the embodiment of the present application, the number of the fan blades 3 on the turntable 2 is set to six, and the six fan blades 3 are arranged in a spiral pattern along the center of the turntable 2. The shapes of the six fan blades 3 are all distorted from the center of the turntable 2 to the periphery of the turntable 2. The thickness of the fan blades 3 can be set to 3 - 8 mm, and the material of the fan blades 3 can be Q345 steel. The yield strength of Q345 steel reaches 345 MPa, which is higher than that of ordinary carbon structural steel, and has good plasticity and weldability, facilitating processing operations such as cutting, bending, and welding.

[0024] Referring to Figure 1 and Figure 2 , a maintenance opening 16 is provided at the top of the housing 1. A cover plate is bolted to the housing 1, and the cover plate covers the maintenance opening 16. In the embodiment of the present application, the cover plate can be made of a transparent material, such as acrylic material, so as to facilitate timely observation of the internal situation of the housing 1.

[0025] Referring to Figure 1 and Figure 2 , the driving device includes a driving motor 11 arranged on the housing 1. The turntable 2 is connected to the output end of the driving motor 11 through a connecting component. In the embodiment of the present application, the driving motor 11 can specifically be a 60V 4KW DC brushless stepless speed regulation motor with a speed regulation range of 0 - 4000 R / MIN. The connecting component includes a connecting shaft 12 arranged at the output end of the driving motor 11. A connecting key 13 is arranged on the outer edge of the connecting shaft 12. An installation hole 14 is opened at the center of the turntable 2, and an installation groove 15 matching the size of the connecting key 13 is opened on the hole wall of the installation hole 14. The connecting shaft 12 passes through the installation hole 14 and the connecting key 13 is inserted into the installation groove 15.

[0026] Therefore, start the drive motor 11 to drive the connecting shaft 12 at the output end of the drive motor 11 to rotate. Since the connecting shaft 12 passes through the mounting hole 14 and the connecting key 13 is inserted into the mounting groove 15, the turntable 2 is driven to rotate synchronously with the connecting shaft 12. The precise matching of the connecting key 13 and the mounting groove 15 ensures the transmission accuracy between the drive motor 11 and the turntable 2, reduces the vibration and noise caused by transmission clearance or error, enables the turntable 2 to stably rotate following the connecting shaft 12 at the output end of the drive motor 11, and guarantees the stability and reliability of the transmission.

[0027] Referring to Figure 2 and Figure 3 , Method 1: The crushing device includes a plurality of tooth grooves 4 formed on the end face of the fan blade 3 facing away from the turntable 2. The distance between adjacent tooth grooves 4 gradually increases in the direction from the center of the turntable 2 towards the outer edge of the turntable 2.

After crushing, the gap between the sundries decreases, the volume collected inside the housing 1 increases, and thus the collection efficiency and loading efficiency are improved.

[0029] Referring to Figure 2 and Figure 3 , Method 2: The crushing device includes a plurality of mounting posts 5 provided on the fan blade 3. In the embodiment of the present application, the number of mounting posts 5 on each fan blade 3 is set to four and is evenly distributed on the fan blade 3. Connecting posts 6 are respectively provided on the plurality of mounting posts 5. A cutting block 7 is rotatably connected to the outer edge of the connecting post 6. A connecting hole 9 matching the size of the connecting post 6 is formed on the cutting block 7.

Therefore, the operator can easily and conveniently detach the mounting column 5 from the fan blade 3, thereby realizing the detachable setting of the mounting column 5. It has stronger flexibility and is convenient for replacing and repairing the worn crushing device.

[0032] In addition, it should be noted that the two ways of the crushing device in the embodiments of the present application can be used separately or in combination. When used in combination, taking the number of a plurality of fan blades 3 as six as an example, three of the fan blades 3 can be provided with the crushing device of the first method, and the other three fan blades 3 can be provided with the crushing device of the second method. Different ways of crushing devices can be provided between adjacent two fan blades 3, so as to facilitate dealing with sundries of different sizes and weights at the same time. Light sundries can be cut and crushed by the first method, and heavy sundries can be cut and crushed by the second method, improving the crushing effect on sundries.

[0033] The implementation principle of the embodiments of the present application is as follows: Start the driving motor 11. The driving motor 11 drives the turntable 2 to rotate at a high speed. Thus, the turntable 2 drives a plurality of fan blades 3 to rotate at a high speed to form a negative pressure, causing air to flow into the housing 1 and sucking sundries such as leaves and garbage into the housing 1 at the same time. The high-speed rotation of the fan blades 3 drives the sundries to rotate with the rotation of the fan blades 3. When rotating at a high speed, a plurality of tooth grooves 4 cut the light sundries, and the cutting block 7 shakes on the connecting column 6, and the heavy sundries can be crushed under the knocking of the cutting block 7.
