[0061] The dust suction mechanism sucks the road surface garbage into the treatment box 2, and conducts rough crushing through the primary treatment mechanism. The garbage enters the secondary treatment mechanism through the first opening 4 at the bottom of the partition 3 for secondary crushing. Finally, the screening mechanism classifies the particles, the qualified garbage is collected, and the unqualified particles are returned to the treatment box 2 through the recycling mechanism for cyclic treatment. The combination of primary coarse crushing and secondary fine crushing avoids large pieces of garbage directly entering the fine components and causing blockages; the unqualified particles after screening are automatically sent back, reducing the need for manual cleaning and improving the resource utilization rate.

[0062] For a further optimized solution, the dust suction mechanism includes a first connecting plate 6 arranged below the vehicle body 1.

The top surface of the first connecting pipe 10 is fixedly connected with a second connecting pipe 11. One side of the second connecting pipe 11 close to the treatment box 2 extends into the top of the treatment box 2 through a fourth connecting pipe 30 and is communicated with the first air guiding part.

[0063] The dust suction mechanism adjusts the distance between the dust suction port 8 and the ground through the electric telescopic rod 7 to ensure the dust suction effect.

[0065] The first air suction fan 12 extracts the garbage through the fourth connecting pipe 30 and sprays it vertically downward onto the first guide plate 13, using gravity to accelerate the garbage to fall to the crushing part. The vertical air flow guides the garbage to fall concentratedly, avoiding scattered accumulation, and using gravity to assist in conveying, reducing the power requirement of the fan.

[0066] For a further optimized solution, the first treatment part includes first guide plates 13 symmetrically and fixedly connected inside the treatment box 2.

[0072] The hair dryer 22 blows air into the secondary treatment area to suspend the light garbage for secondary cutting; the second induced draft fan 23 sucks the crushed garbage into the collection box 5. The suspended state increases the contact probability between the garbage and the shredding rod 20 and improves the secondary treatment efficiency; the second induced draft fan 23 forms a negative pressure to accelerate the garbage transportation and avoid particle residue.

One end of the screening plate 24 away from the driving part is communicated with the first treatment part through a recycling mechanism.

[0074] The screening plate 24 vibrates through the driving part (cam 27). The qualified particles fall to the bottom of the collection box 5, and the unqualified particles are guided to the recycling mechanism through the baffle 25. The vibrating screening plate 24 prevents the sieve holes from being blocked, and the baffle 25 is linked with the recycling mechanism to realize automatic sorting of particles, reducing manual intervention.

[0075] For a further optimized solution, the driving part includes a third motor 26 fixedly connected to the inner wall of the collection box 5. The output shaft of the third motor 26 is fixedly connected to a cam 27, and the cam 27 abuts against the bottom surface of the screening plate 24. The third motor 26 drives the cam 27 to periodically lift the screening plate 24, generating high-frequency vibration to promote screening.
