Electromagnetic drive control device for water and fertilizer liquid

Abstract

The invention relates to the technical field of agricultural machinery, in particular to an electromagnetic drive control device for water and fertilizer liquid. The device comprises a water and fertilizer dissolving mechanism, a flow adjusting mechanism and a driving control device; the water and fertilizer dissolving mechanism comprises a fertilizer dissolving container and a traveling wave magnetic field generator; the traveling wave magnetic field generator is arranged in the fertilizer dissolving container; the traveling wave magnetic field generator comprises magnet units arranged at the bottom of the fertilizer dissolving container; the multiple magnet units are arranged in an array manner in the circumferential direction; a liquid outlet pipe is arranged on the fertilizer dissolving container; the flow adjusting mechanism comprises a supporting pipe, a first annular iron core and a cake type coil; the liquid outlet pipe is sleeved with the supporting pipe; the first annular iron core sleeves the supporting pipe; the cake type coil sleeves the supporting pipe; the cake type coil and the first annular iron core are alternately arranged in sequence; the driving control device is respectively connected with the traveling wave magnetic field generator and the cake type coil; and the driving control device is connected with a three-phase alternating-current power supply. Through the electromagnetic drive control device, fertilizer dissolving efficiency can be improved, and the flow speed control cost of the liquid fertilizer is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an electromagnetic drive control device for water and fertilizer liquid. Background technique [0002] At present, drip irrigation technology under mulch film has been popularized in a large area in northern my country. The application of drip irrigation technology under mulch film provides realistic conditions and technical advantages for the simultaneous application of water and fertilizer in the process of crop growth. In the water and fertilizer management process of crops, the fertilizer needed for crop growth is mixed and dissolved with irrigation water, and then the water and fertilizer mixed solution is drip-applied to the crops by using the drip irrigation network under the mulch, which is a relatively common method used in the current agricultural production process. Crop water and fertilizer integrated management technology. Compared with the traditiona...

Problems solved by technology

However, the dissolving efficiency of solid fertilizer in water in the existing method is low, which makes it difficult to control the amount of fertilization and waste fertilizer; moreover, when the flow rate is controlled, due to the large-area pipe network distribution, a water pump that can adjust the speed and a water pump that can adjust the opening are required. There are many solenoid valves, which greatly increase the cost of equipment and field lines and the complexity of control
