During existing agriculture forestry planting, irrigation system and fertilization system can not carry out precision behaviour to farmland Make, and then causes the irregular plant growth in entire farmland or fertilizer application amount and water consumption to be much higher than and expect just Normal consumption value, so that the practicability of irrigation system is not high and cost is promoted suddenly;It is to meet the needs of modern agriculture forestry planting, i.e., smart Trueization is realized with a low cost pouring purpose, and inventor designs a kind of Intelligent irrigation system, i.e., is embedded in farmland using multiple Soil moisture sensor, the water content situation of soil in real-time monitoring farmland, and according to the specific fertilising period, intelligence can be passed through Energy irrigation system carries out targetedly pouring to plant all or local in farmland and handles, to ensure liquid manure in maximum journey Agree with the growing way of plant on degree.
It is deployed firstly the need of to liquid manure ratio, i.e., water inlet pipe is connected to external pond, is distinguished by three-way flow divider valve It is filled the water into secondary mixing chamber and primary mixing chamber, then injects fertilizer into primary mixing chamber by feed pipe, and first In grade mixing chamber, the water flow ejected in branched pipe can be acted on directly to flabellum, and then drive central axis and remaining several A flabellum starts turning, so that fertilizer is stirred with the water flow come into primary mixing chamber, and when primary mixing chamber In liquid manure magma when reaching a certain concentration, liquid manure magma can enter in secondary mixing chamber along permeability hole, start main motor, into And PRIMARY STIRRING leaf and secondary paddle is driven to be stirred the liquid in secondary mixing chamber, and when in secondary mixing chamber When strength of fluid reaches irrigation norm, starts water pump, mix the liquid manure liquid finished and be then delivered to each outer tube through delivery pipe In;And when specifically pouring, multiple outer tube equidistant intervals being connected to delivery pipe are arranged in farmland, and due to outside each The two sides of set are equipped with row's spray apertures, and two rows of spray apertures are distributed along the axisymmetrical of outer tube, and two rows of spray apertures and outer The plants on both sides root of casing is corresponding, i.e., the liquid manure in delivery pipe directly can reach root system of plant by spray apertures, and pour institute The liquid manure liquid needed enters in delivery pipe after passing through main control valve, then successively enters in outer tube along multiple electronic valves, starts Driving motor in arc-shaped cover, driving driving gear rotation, and then annular tooth band and inner sleeve is driven to start turning, due to electricity There are gaps between sub- valve and one end end face of inner sleeve face delivery pipe, therefore the rotation of inner sleeve is not by outer tube and electricity The interference of sub- valve, and after inner sleeve turns to spray apertures and permeable hole centering, the liquid in inner sleeve is successively successively by permeable Hole, spray apertures are projected to plant root, and the output end of driving motor persistently rotates, and spray apertures and permeable hole are realized and misplaced, liquid Body stops outer spray, and the liquid manure liquid for falling into plant root before at this time then infiltrates into root system of plant using this section of time slot, this Class mode and the mode different from persistently sprayed, will not absorption to root system of plant and breathing cause excessive load, such as This, moves in circles, and under intermittent periodic quantitatively pouring mode, can improve the absorption of root system of plant to the full extent Efficiency, to realize that the precision low cost of modern reading intelligent agriculture is poured.Wherein, the permeable hole number of rows on inner sleeve can increase or It is to reduce, the injection frequency of liquid in spray apertures on outer tube is replaced with this, i.e., the difference of different plants is poured in matching farmland Filling demand.
Wherein, when liquid manure is deployed, mixing chamber is divided into two chambers, i.e., primary mixing chamber and secondary mixing chamber, The water filling of two chambers carries out simultaneously, and the main chamber that secondary mixing chamber is deployed as liquid manure, and primary mixing chamber is as liquid manure tune The secondary cavity matched, the water needed in water filling is different, and therefore, the internal diameter of the branched pipe of applicant's design is less than the interior of supervisor Diameter, fertilizer, which enters after primary mixing chamber, is mixed to form liquid manure magma with the water of deposition, and the concentration of liquid manure magma is higher at this time, and benefit Liquid manure magma is stirred with central axis and multiple flabellums, to avoid occurring in primary mixing chamber, chemical fertilizer is hardened or heap Product, when the liquid level in primary mixing chamber rises to positioned at plane where the permeability hole of floor level position, liquid manure magma by Gradually from being overflowed into permeability hole into secondary mixing chamber, and there is a large amount of new injection water in secondary mixing chamber, while Under the agitaion of PRIMARY STIRRING leaf and secondary paddle, chemical fertilizer magma can be diluted in a short time, to meet plant filling The demand irrigate;Since branched pipe is constantly injected into primary mixing chamber, it is responsible for and equally continues to fill the water into secondary mixing chamber, so that Multi-stage stirring can be realized by the chemical fertilizer raw material that feed pipe injects, thoroughly avoid occurring during transport blocking or be in granular form Chemical fertilizer occur, reduce the probability of transfer pipeline blocking, while the absorption of plant can be accelerated, increase irrigation efficiency.
The spray apertures are rounded after tiling with permeable hole, and the internal diameter of the spray apertures is greater than the interior of the permeable hole Diameter.Further, spray apertures are rounded after tiling with permeable hole, i.e. the inner wall and end surface side of liquid device to hole in outside injection The impact that edge is formed is smaller, and the liquid sprayed is cylindrical, and liquid increases in the distance radiated to root system of plant, so that spray When hole and permeable hole misplace, the range that the water column of truncation falls into plant root increases, and then improves root system of plant and absorbs to liquid manure Efficiency;Axis due to inner sleeve around outer tube moves in a circle, and the internal diameter of spray apertures is greater than the internal diameter of permeable hole, so that thoroughly Between water hole and spray apertures it is existing by be partially communicated to it is complete be connected to, then to part be connected to, i.e., the water column size sprayed outward by Be gradually increased and then be gradually reduced again, when equal with the internal diameter of permeable hole relative to spray apertures, liquid rotated in inner sleeve one The time that a period sprays from inside to outside extends, and in the case where completing the preset precondition for pouring purpose, reduce driving motor Workload, while increasing pouring efficiency.
Rounded rectangle after the spray apertures and permeable hole tiling, and the width of the spray apertures is greater than the permeable hole Width.Further, the inner wall of rounded rectangle after spray apertures and permeable hole tile, i.e. the liquid device to hole in outside injection And the impact that end face edge is formed is smaller, and the liquid sprayed is cylindrical, liquid increases in the distance radiated to root system of plant When greatly, so that spray apertures and permeable hole misplace, the range that the water column of truncation falls into plant root increases, and then improves root system of plant To liquid manure absorption efficiency;Axis due to inner sleeve around outer tube moves in a circle, and the internal diameter of spray apertures is greater than permeable hole Internal diameter so that between permeable hole and spray apertures it is existing by be partially communicated to it is complete be connected to, then to part be connected to, i.e., spray outward Water column size is by being gradually increased and then being gradually reduced again, and when equal with the internal diameter of permeable hole relative to spray apertures, liquid is in inner sleeve The time that a cycle of pipe rotation is sprayed from inside to outside extends, and in the case where completing the preset precondition for pouring purpose, it reduces The workload of driving motor, while increasing pouring efficiency.
