Institute of Agricultural Mechanization of Shenyang Pan Yu Sun Hongsong's new technique of extermination of herbs and cultivating grasses has created a good ecological environment for crops and is also an indispensable link in the realization of agricultural mechanization. The 3WZ-1000 type tractor dual-use multi-functional traction fight drugs is a new machine developed by the Shenyang Institute of Agricultural Mechanization. First, the main purpose 1, spraying a variety of chemical herbicides, soy, corn, vegetables, rice and other crops before sowing, pre-emergence soil treatment and seedling grass. 2. Spray various insecticides and sterilizers to prevent crop pests and diseases. 3, spraying foliar fertilizer and various trace elements. Second, the main performance 1, transmission mode The machine uses the ground wheel drive, supporting power is not limited, through the sprocket of the two-stage growth, so that the pump to obtain a certain range of speed during normal operation. This transmission method is simple in structure, easy to install and reliable in performance. It is the best design for the drive system of traction fight drugs, and both animal power and tractors can be towed. 2. The form of the drug pump The machine adopts a dual-cylinder piston pump with stable displacement and an accumulator to make energy utilization more reasonable. Its role is to make the liquid chemical to obtain a stable and uniform injection pressure, reduce the non-uniformity of the hydraulic pump discharge caused by changes in the unit forward speed, and ensure uniform liquid spray volume. 3, filter purification This machine adopts three-stage filtration purification measures, in the drug liquid into the tank, the tank into the pipeline system before the nozzle are set on the filter to avoid the operation of fine sand, debris mixed with liquid medicine, greatly Enhanced atomization of the nozzle. 4. The medicine tank of the medicine tank adopts a spherical structure. Its main feature is that during chemical mixing process, chemicals can be suspended in the container. When the unit passes through convex and concave surfaces, the liquid is kept stable and no vortex phenomenon occurs. Even if there is little liquid left, the unit can still Normal operation. 5, the unique piping system Because the herbicide itself has the characteristics of easy precipitation, often impede the normal spray nozzle, reduce the effect of disinfestation. Therefore, set the return nozzle at the bottom of the ball tank. When the normal operation, through the role of the backwater nozzle, the formation of high pressure backwater, continue to stir the medicine tank of traditional Chinese medicine, and always make the liquid evenly mixed in water. 6, the nozzle drip drip device leakage will cause local overdose, so that the crop injury, dead seedlings, resulting in reduced production. The machine drip-proof system uses the principle of elastic deformation of the spring to fundamentally solve the nozzle drip problem. Through the multi-point operation of more than 600,000 hectares of herbicide-free cultivator for many years, it has proved that the drip-proof device is safe and reliable.
