Irrigation system for greenhouse water and fertilizer integration

Abstract

The invention discloses an irrigation system for greenhouse water and fertilizer integration. The system comprises a blending box, a rotating rod is fixedly arranged at the output end of a rotating motor, an EC sensor and a PH sensor are fixedly arranged on the side wall of an inner cavity of the blending box, a water and fertilizer filter screen is fixedly arranged at the joint of a communicatingpipe and the blending box, and brushes are arranged on stirring blades close to the EC sensor, the PH sensor and the water and fertilizer filter screen. A fertilizer box is arranged above the blending box, and an impact ball is fixedly arranged at the end part of an extension rod. A three-way pipe is arranged on the blending box in a communicating mode, a first branch pipe is communicated with aninner cavity of the blending box, a second branch pipe is communicated with a rainwater collecting box, and a third branch pipe is communicated with a water inlet pipe. According to the irrigation system for greenhouse water and fertilizer integration, the rotating rod in the irrigation system can clean the EC sensor, the PH sensor and the water and fertilizer filter screen while stirring water and fertilizer mixed liquid, measurement is accurate, blockage is avoided, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of water and fertilizer irrigation, in particular to an irrigation system for integrating water and fertilizer in a greenhouse. Background technique [0002] In the prior art, a greenhouse water and fertilizer integrated irrigation system with the application number "201910793831.1" includes a shed body; it also includes a water and fertilizer mixing delivery mechanism and an irrigation mechanism, wherein the water and fertilizer mixing delivery mechanism is set in the shed On the outer side of the body, the irrigation mechanism is arranged at the bottom of the ceiling in the shed, and the water and fertilizer mixing and conveying mechanism is connected with the irrigation mechanism through a water pipe, and a power box is arranged on the shed body , the power box is respectively connected with the water and fertilizer mixing conveying mechanism and the irrigation mechanism. The integrated water and fertiliz...

Problems solved by technology

[0003] However, there are still obvious defects in its use: 1. The above-mentioned device does not have the function of detecting the EC value and PH value of the water-fertilizer mixture, and it is difficult to accurately measure the properties of the water-fertilizer mixture. The configuration of the liquid is unreasonable, not only can not play an effective role in fertilizing, but will damage the root system of the plant; 2. The above-mentioned device directly transports the water-fertilizer mixture into the water collection tank through the water delivery pipe, but it cannot guarantee that the fertilizer has completely dissolved in this process. In the water, if the dissolution is not complete, the fertilizer will not only block the water pipe, but also block the sump, irrigation pipe network and irrigation nozzle, making the irrigation system damaged and ineffective, and the maintenance work is cumbersome, which will affect the use; 3. The fertilizer in the above device And water mainly depends on manual addition, it is difficult to accurately measure the amount, and there are often ratio errors, so it is not suitable for fine irrigation management
