This invention belongs to the field of agricultural machinery technology and discloses an intelligent agricultural weeding device for agricultural facilities, including a vehicle body. A collection device is located on the outer side of the vehicle body, comprising a connecting frame, a discharge shaft, a sliding column, an L-shaped rod assembly, a threaded block, a diagonal rod, a pushing block, a slot, a triangular block, a spring, and a barb. This invention utilizes the cutting teeth on the outer side of the rotary tiller to thoroughly chop weeds. Combined with the L-shaped rod assembly and the barb on the triangular block, it achieves integrated weeding and collection, preventing weeds from regrowth in the soil and improving weeding efficiency. The collected weeds can be centrally discharged for easy subsequent processing and resource recycling. A probe detects weed information in real time, and the control panel precisely controls the first, second, and third drive motors, achieving automated weeding operations without manual identification or operation, significantly improving weeding efficiency. Simultaneously, it accurately locates weed areas, reducing accidental damage to crops and ensuring agricultural production quality, which is beneficial for practical application and operation.

The present application relates to tea tree planting technical field, disclose a kind of weed removal device for tea tree planting, including drive trolley and setting on drive trolley shell one and shell two, shell two is fixedly arranged in the just above shell one, and shell one is communicated with shell two, the inside of shell two is provided with grass shoveling assembly;The present application is set by grass shoveling assembly, so that oil cylinder one drives mounting plate and oil cylinder two, shovel lifting, oil cylinder two drives two symmetrical inclined shovels open and close, can be in soil with weed and its root system associated part of soil whole shovel, solve the problem that only above stem of weed can be cut in prior art and cannot remove root system;Cooperate with soil breaking component to break up and separate the shoveling object, and weed and its root system are collected by grass storage box, realize the complete removal of weed from root system to stem, effectively avoid weed growth again due to root system residue, significantly improve weeding effect.
