Description
Technical Field
The invention belongs to garden and agricultural irrigation, and relates to a ring-root pressure-stabilizing irrigator and a working method thereof.
Background
With the improvement of living standard, people have higher requirements on eating fresh fruits and leisure entertainment, so that the planting area of fruit trees, garden nursery stocks and green plants in parks is gradually enlarged. The planting management technology of arbor species is different from that of ordinary crops, and the ordinary irrigation technology is not beneficial to the growth and development of arbor roots.
Novel water-saving irrigation technologies such as small pipe outflow, drip irrigation and micro-sprinkling irrigation are applied, but the trees are only irrigated in a strip shape or a dot shape, the wetting zone is narrow, and the root system of the trees easily grows into a flat shape along the wetting zone. The subsequent technological improvement includes leading water with micro pipe around the tree root, installing several micro nozzles or drippers on the micro pipe, resulting in waste of the irrigation emitter and raised cost. There are also special ring root douches, which are in the form of micro-tubes around the tree root, with water outlets or water outlets installed on the micro-tubes, but the outflow is not uniform. Some seedlings are planted on sloping fields, especially in areas with large terrain difference, and the general root-surrounding irrigators cannot meet the irrigation uniformity requirement.
Disclosure of Invention
The invention provides a ring-root pressure-stabilizing irrigator, which can realize stable irrigator outflow in blocks with different terrains.
The invention adopts the following technical scheme:
a ring root pressure-stabilizing douche comprises a pressure-stabilizing douche and a water outlet pipe connected with the pressure-stabilizing douche;
the pressure-stabilizing irrigator comprises a pressure stabilizer plug-in piece provided with a water inlet and a pressure stabilizer bearing piece provided with a water outlet, and the pressure stabilizer plug-in piece is inserted into an inner cavity of the pressure stabilizer bearing piece; a water filtering window for filtering water is arranged in the voltage stabilizer plug-in, and a flow channel for energy dissipation is arranged below the water filtering window; a pressure compensation cavity is arranged in the pressure stabilizer bearing part, a membrane groove is formed between the bottom of the pressure stabilizer plug-in and the pressure compensation cavity, an elastic membrane is arranged in the membrane groove, and the elastic membrane is positioned on the pressure compensation cavity; the pressure compensation cavity is provided with a pressure compensation cavity converging port; an annular cavity is formed between the outer wall of the pressure compensation cavity and the inner wall of the pressure-stabilizing irrigator bearing piece;
the outlet pipe encircle the trunk round, be equipped with even apopore on the outlet pipe.
In the above technical scheme, further, the water inlet of the pressure-stabilizing irrigator can be directly inserted into the capillary or can be used for introducing water through a hose.
Furthermore, the water outlet of the pressure-stabilizing douche is connected with a water outlet pipe through a hose, and the water outlet pipe is connected with the hose through a tee joint.
Further, the stabilizer insert and the stabilizer holder are fastened together by a bayonet.
The invention also provides a working method of the ring-root pressure-stabilizing irrigator, which specifically comprises the following steps:
water enters the pressure-stabilizing douche from the water inlet of the pressure-stabilizing plug-in unit, then flows out of the water filtering window, and flows into a flow passage section formed by the closing of the pressure-stabilizing plug-in unit and the pressure-stabilizing bearing unit for energy dissipation. After energy dissipation, water flows out of the flow channel, flows into an annular cavity between the outer wall of the pressure compensation cavity and the inner wall of the pressure-stabilizing irrigator bearing piece, and then flows into the pressure compensation cavity through a confluence port of the pressure compensation cavity. The water flow is regulated by the elastic membrane and then flows out from the water outlet of the pressure regulator bearing piece; then the water enters the water outlet pipe through the hose and finally irrigates the tree through the water outlet on the water outlet pipe.
The invention has the following advantages:
in the ring-root pressure-stabilizing irrigator, the water outlet pipe can adopt the size of a common micro pipe in the current market, and holes are uniformly punched on the pipe. The length of the micro-tube can be cut according to the thickness of the tree root, or the micro-tube can be replaced along with the gradual thickness of the tree.
Many similarly assembled emitters in the market at present lack water filtering windows, the inlet of a common tube-on-tube dripper is directly inserted into a capillary tube, or the inlet is provided with simple filtering in a cross shape, so that the interception effect on impurities in water is basically zero, and thus, the emitters are subjected to great blocking risk. In the past, a large amount of silt is accumulated in the douche (including the flow channel), the douche is not maintained timely, and the douche can only be replaced. The pressure-stabilizing douche of the invention is internally provided with a large-area water filtering window, which can well avoid the defects. Even if silt is accumulated, the smoothness of the flow channel cannot be influenced, and the pressure-stabilizing irrigator is divided into two parts, so that the assembly, the disassembly and the cleaning are convenient.
The form and the structural dimensions of the flow channels can be specifically designed and determined according to the flow requirements. Finally, water enters an annular cavity formed between the outer wall of the pressure compensation cavity and the inner wall of the pressure-stabilizing irrigator bearing piece from the water outlet of the flow channel, then enters the pressure compensation cavity along the confluence port of the pressure compensation cavity, and finally flows out from the water outlet of the pressure-stabilizing irrigator bearing piece. The user can directly replace the plug-in of the voltage stabilizer according to the water demand requirement of the plant, and the outflow of the voltage-stabilizing irrigator is adjusted.
The elastic membrane is arranged in a membrane groove formed by the voltage stabilizer plug-in and the voltage stabilizer bearing part and divides the voltage-stabilizing irrigator into an upper water cavity and a lower water cavity. When the water pressure is high, the water flow speed is high, the pressure acting on the elastic diaphragm is high, the elastic diaphragm deforms and extrudes downwards, the water quantity accumulation in the pressure compensation cavity is reduced, and the outflow rate is reduced. When the water pressure is small, the pressure acting on the elastic diaphragm is not enough to deform the diaphragm, the amount of converged water in the pressure compensation cavity is large, and the outflow rate is supplemented. The pressure compensation can well avoid the influence of uneven outflow of the douche caused by uneven terrain. In the same type of ring-root irrigators, the pressure compensation link is lacked. The invention well solves the problems of slope nursery stock planting and maintenance and different growth vigor of nursery stocks due to uneven water content.
