The invention discloses a hob type weeding machine for a paddy field and an implementation method of the hob type weeding machine, and belongs to the technical field of agricultural production. The hobbing cutter type weeding machine for the paddy field comprises a rack, paddy field wheels are symmetrically arranged on the outer side of the rack, a grass collecting box is arranged on the advancing side of the rack, a hobbing cutter device is arranged on the side, opposite to the grass collecting box, of the rack, a weeding assembly is arranged on the side, away from the grass collecting box, of the hobbing cutter device, and the hobbing cutter device is matched with the weeding assembly. The problems that an existing weeding machine cannot adapt to paddy field operation, and paddy field weeds cannot be prevented from growing again are solved. Through the unique design of the hob device and the weeding assembly, the first sawtooth strip on the weeding plate is matched with the third sawtooth strip on the tooth-shaped annular belt, weeds are firmly clamped and wound into a gap between the bottom of the weeding plate and the bottom of the tooth-shaped annular belt, the weeds are pulled up with roots along with continuous rotation of the weeding plate, and the weeding effect is achieved. The problem that a traditional weeding machine can only cut off weeds and cannot thoroughly remove the weeds is solved, and the weeding efficiency is improved.

This invention relates to the field of secondary water supply technology, and discloses a secondary pump station-based differentiated water supply system. The system includes an activated carbon filtration device, an ultrafiltration device, a nanofiltration device, an ultrafiltration water tank, a nanofiltration water tank, a sodium hypochlorite disinfection control device, and an ozone disinfection control device. During water usage, a flow sensor detects the total water consumption and real-time water flow over a period of time, and based on the detection results, either the sodium hypochlorite disinfection control device or the ozone disinfection control device is selected for disinfection. This invention provides a secondary pump station-based differentiated water supply system that introduces ozone or sodium hypochlorite disinfection into the water flow after activated carbon filtration and ultrafiltration. While ensuring that the disinfectant levels in the tap water meet requirements, it maximizes the taste of the drinking water and avoids the problem of microbial regrowth in domestic water pipes and drinking water pipes due to insufficient residual disinfectant after activated carbon filtration, effectively preventing secondary pollution of the water supply.

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 relates to the technical field of tap water secondary water supply, and discloses a secondary pump room dual water supply system which comprises an activated carbon filtering device, ultrafiltration equipment, nanofiltration equipment, an ultrafiltration water tank, a nanofiltration water tank, a sodium hypochlorite disinfection control device and an ozone disinfection control device. The total water consumption and the real-time water flow in a period of time are obtained through detection of the flow sensor, and one of the sodium hypochlorite disinfection control device and the ozone disinfection control device is selected for disinfection according to a detection result. According to the dual water supply system for the secondary pump room, ozone disinfection or sodium hypochlorite disinfection is introduced into the water flow filtered by the activated carbon and the ultrafiltration membrane, so that the taste of direct drinking water is guaranteed to the greatest extent on the premise of guaranteeing that the disinfectant index of water at the tail end of a faucet meets the requirement; meanwhile, the problem of regrowth of microorganisms in the domestic water pipeline and the direct drinking water pipeline caused by insufficient disinfectant residue after the raw water is filtered by the activated carbon is also avoided, and secondary pollution of water supply is effectively avoided.

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.
