Technical Field
The invention belongs to the field of agricultural irrigation equipment, and particularly relates to a water and fertilizer integrated irrigation device for a field.
Background
Tobacco belongs to large-scale herbaceous plants planted on ridges, and is irrigated by adopting simple and rough ridge-to-ridge flood irrigation in the prior art, but in recent years, the mode is found to easily cause mutual infection of diseases among tobacco plants, particularly, diseases such as black shank, root black rot and the like with high fatality rate are easily infected through water flow. Meanwhile, the invalid evaporation rate of water in flood irrigation among ridges is higher, and the waste of water resources is caused. In the prior art, tobacco plants are irrigated by adopting a similar sprinkling irrigation method, for example, holes are pricked at equal intervals in a plastic pipe, so that each hole is irrigated by draining water corresponding to the root of the tobacco plant, and meanwhile, water and fertilizer integrated irrigation is realized by combining water and fertilizer. However, this approach has two disadvantages: 1) when a pump pumps water into a pipeline, water is discharged from a hole close to the pump at first, and water is discharged from a hole far away from the pump at last, so that water supply and fertilizer supply among tobacco plants are uneven, particularly, tobacco leaves are greedy and late-maturing due to excessive application of nitrogen fertilizer, and further tobacco leaves in the field cannot uniformly fall yellow and mature; 2) the pump machine pressurizes water, so that the pressure of water flow discharged from the holes is large, ridge soil loss and collapse are easily caused, meanwhile, the water flow is easily splashed to other places, and the problem of fertilizing amount difference caused by different water outlet time is aggravated in a phase change manner.

Taking the tobacco ridge operation as an example, the working process of the invention is as follows:
each irrigation pipe is placed between two adjacent cigarette ridges in parallel along the extension direction of the cigarette ridges, meanwhile, the drain pipes extending out of two sides of the side wall of the outer pipe are placed above ridge soil at the roots of the two cigarette ridges, (the row spacing of the cigarette plants has fixed data requirements, so the drain pipes can be arranged and designed during production according to corresponding data), then the water pump is connected with each irrigation pipe, and due to the arrangement of the inner pipe balancing weight, the balancing weight can be effectively kept in a state close to the ground, the situation that the irrigation pipes generate circumferential rotation after pressure water flow is injected into the irrigation pipes is prevented, and finally the two rows of water pipes are in a non-horizontal state.
The water pump is started to pressurize the liquid fertilizer mixture (the liquid fertilizer mixture is described below) and then the liquid fertilizer mixture is pumped into the inner pipe of each irrigation pipe. Because the delivery port of every inner tube shields through the portion of expanding and the dead weight of counter weight pole makes it constitute a gravity valve structure in addition, this just makes the inner tube only by mixed liquid full back, just can act on the bottom surface of the big portion of expanding with water pressure, thereby can push up the portion of expanding and make the delivery port expose after water pressure is greater than the gravity of end cap mechanism. Mixed liquid is discharged to the outer pipe from the delivery port after exposing in, along with mixed liquid in the promotion of outer intraductal liquid level and submergence end cap mechanism back, because the density of bulk portion, water conservancy diversion semi-ring and stopper is far less than mixed liquid, so end cap mechanism relies on mixed liquid to its buoyancy to offset the dead weight of counterweight rod, keeps the normally open state of delivery port to avoided because pump assembly supplies the phenomenon emergence of not enough pressure initiation end cap mechanism shutoff delivery port of certain delivery port department that pressure is not enough or other reasons lead to. So that the water outlets of the shunt pipes are uniform and the mixed liquid is discharged at the same time.
And meanwhile, when the plug mechanism has the maximum ascending stroke under the action of buoyancy, the limiting block at the top of the expansion part pushes against the inner wall of the liquid discharge pipe, the flow guide half rings at two sides of the expansion part are in a coaxial state with the inner pipe and the outer pipe, the mixed liquid discharged from the liquid outlet under pressure is blocked by the inner annular surface of the flow guide half ring, and the mixed liquid is guided to a gap between the flow guide half ring and the inner wall of the outer pipe to flow upwards to the liquid discharge pipe. The whole flow path can form turbulent flow at the joint of the flow guide half ring and the expansion part, the bottom of the flow guide half ring, the joint of the inner wall of the outer pipe and the liquid discharge pipe and the bending part of the liquid discharge pipe, so that the kinetic energy of the mixed liquid can be consumed to reduce the flow speed of the mixed liquid, and meanwhile, the turbulent flow can be utilized to form a shearing effect to improve the water-fertilizer mixing effect of the mixed liquid. Meanwhile, when clear water is injected into the pipeline to clean the pipeline in the later period, the residual water and fertilizer components at the corresponding dead corners of the pipeline can be effectively removed by the turbulent flows.
The mixed liquid discharged from the water outlet still has certain pressure, when the mixed liquid reaches the pipe orifice of the liquid discharge pipe, the mixed liquid pushes the pressure reducing semi-rings and the pressure reducing plates to enable the two pressure reducing semi-rings and the pressure reducing plates to respectively rotate upwards and oppositely around the supporting rod and the supporting shaft relative to the hinge, but due to the existence of the magnet sheet group, the repulsive force of the magnet sheet group resists the upwards and oppositely rotating of the pressure reducing semi-rings and the pressure reducing plates, so that the pressure reducing semi-rings and the pressure reducing plates block the outward discharge of the mixed liquid, the kinetic energy of the mixed liquid is eliminated, the flow rate of the mixed liquid is reduced, the mixed liquid smoothly flows out from the pipe orifice of the liquid discharge pipe and drops on ridge soil.
Compared with the prior art, the invention has the following advantages: the invention has simple structure, can ensure that the drain pipe at each plant can supply water as simultaneously and uniformly as possible, reduces the water pressure to ensure that the water flow is level and flows into ridge soil, and improves the irrigation efficiency.
