When the fallen leaf collection vehicle is cleaning, the detection component 5 detects the thickness of the fallen leaves on the road and feeds back the detection result to the controller 12. The controller 12 controls the air source component 8 to select a suitable gear to work according to the thickness of the fallen leaves. In addition, the detection component 5 detects the dust near the crushing component 4 and feeds back the result to the controller 12. When the detection result exceeds the preset value in the controller 12, the controller 12 controls the water source component 9 and the dust suppression component 7 to work, so as to avoid the generation of a large amount of dust when the fallen leaves are crushed, causing secondary harm to the environment. When the road surface is relatively wet, the operator controls the starting component 6 through the controller 12 to operate, and the air source component 8 provides the air source for the starting component 6. The starting component 6 blows the wet fallen leaves stuck on the road surface off the ground, which is convenient for the crushing of the crushing component 4 while also avoiding the residue of fallen leaves.

[0037] The garbage bin assembly 2 includes a box body 21, the inner cavity of the box body 21 is divided into an exhaust bin 22, a gas delivery bin 23, a clean water bin 24 and a fallen leaf collection bin 25 by an iron plate. The gas delivery bin 23 is located above the clean water bin 24 and at the end of the box body 21 close to the cab 11. The clean water bin 24 contains a water source for dust suppression.

Filter ports 26 are provided on the side walls of the gas delivery bin 23 and the fallen leaf collection bin 25. A feed pipe 27 is fixedly connected to the bottom wall of the box body 21. One end of the feed pipe 27 extends into the fallen leaf collection bin 25, and the other end thereof is connected to the crushing assembly 4. A position sensor 28 is provided on the top wall of the fallen leaf collection bin 25, and the position sensor 28 is connected to the controller 12 signal. The position sensor 28 is used to detect the position of fallen leaves in the fallen leaf collection bin 25 and feed back the detection value to the controller 12. When the height of the fallen leaves is greater than the preset value in the controller 12, the controller 12 reminds the staff to process the fallen leaves collected in the fallen leaf collection bin 25.

The first dust detection unit 51 and the fallen leaf thickness detection unit 52 are both connected to the controller 12 by signal. The first dust detection unit 51 feeds back the detected dust value to the controller 12. When the dust value is greater than the preset value in the controller 12, the controller 12 controls the dust suppression component 7 to perform dust reduction treatment on the crushing component 4. The fallen leaf thickness detection unit 52 detects the thickness of fallen leaves on the road surface and feeds back to the controller 12.

[0039] The first dust detection unit 51 and the second dust detection unit 29 both use micro-photodetectors. The principle of dust detection is as follows: when dust passes through the light-sensitive area, the scattered light is collected by the micro-photodetector, and the micro-photodetector converts the light intensity signal into a voltage signal. The density of the voltage signal corresponds to the unit concentration of the dust. The converted dust concentration is transmitted to the controller 12 after coefficient conversion. The controller 12 issues corresponding instructions based on the feedback value and the preset value.

[0040] The fallen leaf thickness detection unit 52 includes a micro-photodetector A1 and a micro-photodetector A2, the micro-photodetector A2 is connected to the micro-photodetector A1 by signal, the micro-photodetector A1 is connected to the controller 12 by signal, the micro-photodetector A1 is fixed on the side wall of the crushing seat 41 away from the cab 11, and the micro-photodetector A2 is fixed on the side wall of the crushing seat 41 close to the cab 11.

Take B1, B2, ..., Bn on the upper part of the fallen leaves, a total of n monitoring points, and use the micro-photoelectric detector A1 to measure the straight-line distances from point O to B1, B2, ..., Bn in turn as G1, G2, ..., Gn; then calculate the vertical heights from point O to B1, B2, ..., Bn as H1, H2, ..., Hn through the tangent function formula, calculate the thickness of the fallen leaf points B1, B2, ..., Bn through the formula: (Ln=H0+h-Hn), and calculate the weighted thickness I of the fallen leaves within the detection range of the micro-photoelectric detector A1 through the weighted method, the fallen leaf thickness detection unit 52 converts the weighted thickness I of the fallen leaves into an electrical signal, and then feeds it back to the controller 12.

[0041] The lifting assembly 3 includes a support seat 31, a swing seat 32 and a driving member 33. One end of the support seat 31 is fixedly connected to the automobile chassis 1, one end of the swing seat 32 is hinged to the support seat 31, and the other end is connected to the crushing assembly 4.
