Embodiment 1

[0028] Embodiment 1, the flake irrigator used for diverting yellow

[0029]The sheet-shaped irrigator for yellow diversion provided in this embodiment includes an upper casing 1 and a lower casing 2 that cooperates with it. The cross-section along its width direction is a trapezoid with a narrow upper and a lower width, which can reduce the resistance in the direction of the upstream flow; The body 1 is a closed shell, and there are two rows of water inlet grids 3 on its top. Its function is to filter the incoming water, and the larger particles in the water will be blocked by the water inlet grid 3; There is a water outlet grid 4, and a plug plate 5 extending in a direction away from the top of the upper casing 1 is provided near the water outlet grid 4; the lower casing 2 is a casing with an opening at the top, and the lower casing 2 The slot body 7 is arranged at the corresponding position of the insert plate 5, and the slot body 7 is spaced from one end of the width direct...

Embodiment 2

[0031] Embodiment 2, drip irrigation device

[0032] The drip irrigation device provided by the present invention includes a drip irrigation pipe 15 and a plurality of irrigation devices provided in Embodiment 1 arranged in the drip irrigation pipe 15, and a spacing is provided between the irrigation devices along the radial direction of the drip irrigation pipe 15 (not shown in the figure). ); The in-line sprinkler adopts the injection molding technology to realize the integrated design with the drip irrigation pipe 15. The feeding, screening, conveying, quantitative supply and embedding of the sprinkler can be completed continuously and synchronously, and the conveying power can be adjusted according to the production speed of the drip irrigation belt. Ensure that the irrigator can be accurately sent to the bonding position with the drip irrigation pipe 15 and is firmly bonded; the bottom of the drip irrigation pipe 15 is provided with through holes corresponding to the posit...

Abstract

The invention discloses a sheet irrigator for flood diversion and drip irrigation. The irrigator comprises an upper shell body and a lower shell body, wherein the lower shell body is matched with the upper shell body, the upper shell body is a closed shell body, a plurality of water inlet grids are arranged at the top of the upper shell body, at least a row of water outlet grids are arranged at the bottom of the upper shell body, an inserting plate is arranged on the bottom of the upper shell body, which is close to the water outlet grids, and extends towards a direction away from the upper shell body; the lower shell body is provided with an opening at the top, a groove body is arranged in the lower shell body at a position corresponding to the inserting plate, and is matched with the inserting plate, a space is arranged between the groove body and one end of the lower shell body; a water inlet flow passage is arranged in the lower shell body at a position corresponding to the water outlet grids, and extends towards the other side of the groove body through the space; a water outlet of the water inlet flow passage is communicated with at least one silt presedimentation tank, the water outlet of the silt presedimentation tank is communicated with an energy dissipation flow passage; and a water outlet hole is arranged on the bottom of the lower shell body, which is close to thewater outlet of the energy dissipation flow passage. The sheet irrigator can be used for effectively solving the problem of synchronous improvement on hydraulic performance and anti-clogging performance of the irrigator, and is applicable to a flood diversion and drip irrigation system with self-adaptive regulation and control capacity.

Description

technical field [0001] The invention relates to a chip-type irrigation device for drip irrigation for diverting yellow water. Background technique [0002] The Yellow River Basin is a resource-based water-deficient area, with less water and more sand, uncoordinated relationship between water and sand, and extremely unbalanced distribution of water resources and cultivated land resources, which determines the important role of irrigation from the Yellow River in agricultural production. The implementation of total water resources control and the distribution and rational transfer of water rights have become important safeguard measures for the sustainable utilization of water resources in the Yellow River Basin and the coordinated development of social economy and irrigated agriculture. Drip irrigation is a low-pressure and small-flow outflow that transports irrigation water to the root zone of the crop and penetrates into the soil slowly and evenly to meet the needs of crops...
