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 invention provides a weeding composition containing foxacarb, the active ingredients of the weeding composition comprise foxacarb and pyroxasulfone, and the mass ratio of foxacarb to pyroxasulfone is (1-10): (1-10); or the active ingredients of the weeding composition comprise the foxacarb, the pyroxasulfone and the terbuthylazine, and the mass ratio of the foxacarb to the pyroxasulfone to the terbuthylazine is 1: (2-5): (15-25). The weeding composition disclosed by the invention has a remarkable synergistic effect, can be used for remarkably improving the weeding effect of a medicament, reducing the dosage of the medicament, slowing down the generation of pesticide resistance and relieving environmental pollution, can be used for preventing and removing annual weeds of corn, and has an excellent weeding effect.

This invention provides a herbicidal composition containing benzoxam, wherein the active ingredients comprise active ingredient A and active ingredient B; the mass ratio of active ingredient A to active ingredient B is 1:10-10:1; active ingredient A is benzoxam, and active ingredient B is one or both of pyrimethanil and propyzoxystrobin. This herbicidal composition exhibits a significant synergistic effect, significantly improving the herbicidal efficacy of the herbicide, reducing the dosage required, slowing the development of pesticide resistance, and mitigating environmental pollution. This herbicidal composition can be used for weed control in non-cultivated land, demonstrating excellent herbicidal efficacy.

The invention discloses a weed extruding and rubbing and liquid medicine coating device, and belongs to agricultural machinery. The upper end of a hollow shaft stepping motor is connected with a liquid conveying pipe through a clamping seat, the lower end of a motor shaft is fixedly provided with a hanging shaft through a coupler, a fixing sleeve is rotatably sleeved at the lower end of the hanging shaft, the lower end of the fixing sleeve is sequentially provided with an atomizing nozzle, a seepage cylinder and a cylinder type sun gear from the center to the outside, and the cylinder wall of the tooth root of the sun gear is provided with an axial long-strip-shaped through hole. The sponge axial boss is inserted into the through hole and the outer end is exposed; a rotatable cylindrical planetary gear is mounted on a gear shaft at the lower end of the crank arm and is constantly meshed with the sun gear, and a sponge boss is intermittently extruded by tooth crests; the device realizes physical and mechanical damage to stems and leaves of weeds, and at the same time, the herbicide liquid is applied to the damaged part, so that absorption of the weeds to the liquid is promoted, and the device has the outstanding characteristics of good herbicide effect, low consumption of the liquid, low loss of the liquid, low operation cost and light environmental pollution.

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.
