Background technique

At present, there are no large-scale large-scale rainfall machines for farm production in dry farming areas, and no large-scale rainfall machines are found in the agricultural machinery market. Only small-scale sprinklers and structural-type mobile sprinklers are used, but the structural performance is different.

Summary of the invention

The task of the invention is to provide an efficient and practical multi-functional large-scale rainfall machine for large-area crop plant protection in dryland area plains and slope farms, and to improve the farmland automatic monitoring controller monitoring of farm growth by using all-weather agricultural machinery equipment without rain. Improve the environmental protection of water and fertilizer growth elements that are more suitable for the growth of crops, and implement efficient artificial rainfall, mist, smoke, fertilizer, weeding, dusting, disease prevention, and pest control for agricultural production. The task is to complete this task. The dryland area plains and sloping farms need to plan large areas of crops, roads, water pipes, drains and other large-scale crops according to mechanized operations, eliminating the need to smash trenches and flooding floods. Automatically detect the content of various elements in farmland soil, check the water and fertilizer disease requirements of crops, timely supplement crops, need water and fertilizer and disaster prevention, and ensure the harvest of agricultural grain; Multi-function large rainfall machine works like this: Loaded with large scale that has been upgraded by more than four meters High-speed combined harvesting of rainfall machines The plant management machine slowly moves on the farmland road, and connects the underground water pipe into the vehicle water tank to supply water continuously. The vehicle high-pressure water pump is started to supply the pressure water to the pressure liquid tank, and the pressure water of the liquid tank is pressed through the water supply pipe. And the valve is respectively supplied with a plurality of rain machine working injection pipes to work at the same time. At this time, the spray pipe has a plurality of sets of water spray rings simultaneously opening the valve, and a plurality of spray heads installed on the spray ring are sprayed with a large amount of water, and the hydraulic motor drives the fan impeller at a high speed. Rotating generates a huge jet of wind, and sprays the spray water to the farms in the far, middle and near front to implement rapid rainfall. The large rainfall machine can freely adjust the injection angle and range and rainfall density of each jet pipe to adjust the overall jet. After the pipe spray angle, the hydraulic cylinder can make the spray pipe swing to balance the rainfall distribution; the large rain machine has a rotating frame that can perform more than 200 degrees of fan-shaped rotating operation, ensuring wide-width and large-area effective operation; If the water spray ring is used, medium-speed rainfall can be implemented. If a set of water spray rings is closed, the atomized rain can be implemented as a mist operation; Fertilizer to foliar fertilizer, pesticides can be added to govern Insect pests and fogs; adding herbicides to weed the farmland; turning off the water source, inputting smoke or powder from the jet pipe powder input pipe to carry out the smoke spraying operation; at the same time, the large-scale large-scale rain machine can also spray a large amount of high-speed water. Auxiliary fire-fighting and fire-fighting disaster relief can change the local climate humidification to purify the air and the epidemic area spraying and quarantine and reduce disasters; it can also serve the modern military three-chemical chemical mechanized combat operations.
