Description

Tobacco field irrigation equipment of average flowing back

Technical Field

The utility model belongs to tobacco irrigation equipment field especially relates to a tobacco field irrigation equipment of equal volume flowing back.

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 drawbacks: when the pump machine pumps water into the pipeline, the holes close to the pump machine firstly discharge water, and the holes far away from the pump machine discharge water finally, so that water supply and fertilizer supply among tobacco plants are uneven, especially excessive application of nitrogen fertilizer easily causes greedy and late maturity of tobacco leaves, and further causes that the tobacco leaves in the field can not uniformly fall yellow and mature.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a tobacco field irrigation equipment of equal volume flowing back, the utility model discloses simple structure can make the drain pipe of every tobacco plant department just evenly supply water simultaneously as far as possible, guarantees evenly fertilizeing when improving irrigation efficiency.

In order to solve the technical problem, the utility model discloses a technical scheme as follows:

a tobacco field irrigation device capable of uniformly discharging liquid comprises an irrigation pipe arranged on a tobacco ridge, wherein the irrigation pipe comprises an inner pipe and an outer pipe which are coaxially sleeved and closed at two ends, a plurality of water outlets are axially and equidistantly formed in the position, on the side wall of the top, of the horizontally arranged inner pipe, the water outlets are provided with plug mechanisms, and one end of the irrigation pipe is provided with a water inlet communicated with the inner pipe; the lateral wall of the top of the outer pipe is provided with two drain pipes communicated with the water outlet in a way of extending along the tangential direction at the position corresponding to the water outlet, and the other ends of the drain pipes are vertically bent upwards.

Preferably, the plug mechanism comprises an expansion part which completely covers the water outlet and a counterweight rod which is integrally arranged below the expansion part and passes through the water outlet and then is positioned in the inner pipe.

Preferably, the plug mechanism further comprises a flow guide half ring extending along two sides of the expansion part and a limiting block arranged at the top of the expansion part.

Preferably, the limiting block is positioned on the inner wall of the top contact drain pipe, and the flow guide semi-ring is coaxially arranged with the inner pipe and the outer pipe.

Preferably, the expansion part, the flow guide semi-ring and the limiting block are made of foam plates.

The utility model discloses the working process is as follows:

place every irrigation pipe between the cigarette ridge, make two rows of water pipes that the outer tube lateral wall extends simultaneously arrange the ridge soil top that corresponds the tobacco plant root in (because the plant spacing of tobacco plant has fixed data requirement, so the utility model discloses a layout design can be carried out according to corresponding data when producing to the drain pipe), then through the water inlet of pipe connection water pump and irrigation pipe. And (3) starting a water pump, pressurizing the water-fertilizer mixed liquid (the mixed liquid is described below) and pumping the pressurized liquid into an inner pipe of the 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 the phenomenon of the not enough shutoff delivery port of end cap mechanism of certain delivery port department that water pump supply pressure is not enough or other reasons lead to takes place. So that each water outlet of each irrigation pipe is uniform and discharges mixed liquid 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.

Compared with the prior art, the utility model, have following advantage: the utility model discloses simple structure can just evenly supply water simultaneously as far as possible for the drain pipe of every tobacco plant department, guarantees evenly fertilizeing when improving irrigation efficiency.
