These hedges planted into single or double rows have the functions of separating space, blocking vision, reducing noise, beautifying the environment, and have high ornamental value, so they are mostly planted on both sides of roads in various cities. In spring and summer, hedges grow very fast and are susceptible to diseases and pests, but in order to maintain their neatness and health, they need to be frequently pruned and arranged. The broken leaves and branches pruned from the hedges will fall on the road surface, affecting the city appearance, so the broken leaves and branches pruned from the hedges need to be collected and transported in time to ensure the environment is clean; the broken leaves and branches with diseases and pests should be collected and treated in time to prevent the spread of diseases and pests.

[0074] The working process of the present application is as follows:
[0075] Step one:
