Description

Flow-adjustable pear tree drip irrigation device Technical Field The utility model relates to the technical field of pear drip irrigation, in particular to a flow-adjustable pear drip irrigation device. Background The pear drip irrigation device is mainly applied to the field of pear tree planting as a water-saving irrigation device, and water is accurately conveyed to the root of the pear tree in a drip mode through a pipeline system, so that the water resource utilization efficiency can be effectively improved, and the water demand of pear tree growth is met. Such drip irrigation devices generally comprise the following structure: 1. A water source part which can provide sufficient water quantity for the drip irrigation system and generally comprises a reservoir, a water well, a river and the like; 2. The head junction consists of a water pump, a filter, a fertilizer applicator, a pressure gauge and other devices, wherein the water pump is responsible for lifting a water source, the filter removes impurities in water, the fertilizer applicator realizes the integration of water and fertilizer, and the pressure gauge monitors the pressure of a system; 3. The pipeline system consists of a main pipe, a branch pipe and a capillary pipe, wherein the main pipe and the branch pipe are mainly PVC or PE plastic pipelines for water delivery, the capillary pipe is paved at the root of a pear tree, and a dripper is arranged on the capillary pipe; 4. Drippers are key components for slowly dripping water into soil in the form of water droplets. At present, in order to realize the efficient irrigation of pear trees, farmers and enterprises adopt various drip irrigation devices and modes, part of the drip irrigation devices are fixed, irrigation is carried out through pipelines and drippers buried underground, the drip irrigation device has the characteristics of good stability and difficult damage, the movable drip irrigation device can flexibly move according to the change of pear tree planting areas, the irrigation range is convenient to adjust, and the intelligent drip irrigation device is used in some areas and is provided with a sensor and a control system, so that the soil humidity and the pear tree water demand can be monitored in real time, and the irrigation quantity can be automatically adjusted. However, the above-mentioned embodiment still has following problems, in the aspect of flow regulation, the flow regulation function of most drip irrigation devices is comparatively single, be difficult to carry out accurate regulation according to the water demand of pear different growth stages, the moisture evaporation under the different weather conditions, lead to water waste or irrigation insufficiency, in the aspect of detachable maintenance, the part connection of current drip irrigation devices adopts fixed mode mostly, when the problem such as the component of irrigator, pipeline appear blocking, damage, the operation is complicated with the maintenance, consume a large amount of manpower and time cost, seriously influence drip irrigation system's normal operating and life, but this pear drip irrigation device through adjustable flow and detachable design, effectively solved above-mentioned problem, adjustable flow function can control the irrigation water yield, improve water resource utilization efficiency, promote the pear growth, detachable design is convenient for the maintenance of device, wash, adjustment and transportation storage, reduce use cost, promote equipment life and system's flexibility, provide better solution for the irrigation management of pear planting.
