Description

Technical Field

[0001] The invention belongs to the technical field of agriculture and relates to a water-fertilizer integrated device, in particular to a monitoring device for a water-fertilizer integrated system. Background Art

[0002] With the continuous development of urbanization, my country's agriculture is constantly developing towards mechanization and scale, and large-scale farmland is increasing. A complete set of automatic fertilization and irrigation systems is essential. Now, water-fertilizer integrated devices are mostly used for plant irrigation. Water-fertilizer integrated devices are generally composed of water supply system, fertilizer supply system, field irrigation system and monitoring system.

[0003] In the fertilizer supply system of the water-fertilizer integrated device, chemical fertilizers are generally pre-dissolved in water at a certain ratio and then transported to the main irrigation pipe through a venturi tube. In order to ensure that the chemical fertilizers are fully dissolved, the water temperature of the dissolved water must be tested and properly heated under low temperature conditions. However, due to the large volume of the reaction container, the water temperature in various places is often uneven, and the current water temperature monitoring sensors are mostly fixed and cannot reflect the lowest temperature, which may cause fertilizer deposition.

[0004] The patent number is CN112189425A, and the patent name is a monitoring device for a water-fertilizer integrated system, which discloses a water-fertilizer integrated system. However, the device has a complex structure, and the sensor is immersed in the fertilizer for a long time, and fertilizer residues are easily attached to the surface, which affects the accuracy of monitoring.

[0005] In order to solve the above problems existing in the prior art, a monitoring device for a water-fertilizer integrated system was developed. Summary of the invention

[0006] The purpose of the invention is to provide a monitoring device for a water-fertilizer integrated system.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A monitoring device for a water-fertilizer integrated system comprises a guide ring connected by a connector fixed on the side wall of the bottom of an inner cavity of a stirring tank, and a rotating shaft arranged at the bottom of the inner cavity of the stirring tank; a vortex plate and a connecting rod are arranged on the rotating shaft, a sliding block is fixedly connected to the end of the connecting rod, the bottom of the sliding block is slidably connected to the side of the guide ring, the top of the sliding block is connected to the rotating rod, and a temperature sensor is installed on the top of the rotating rod; a fixing rod is arranged on the connecting piece, the top of the fixing rod is fixedly connected to an upper cover plate, a rubber pad is arranged at the bottom of the upper cover plate, and an inner cavity of the rubber pad is provided with an inner groove adapted to the surface of the temperature sensor.

[0008] Furthermore, the guide ring is provided with an embedded groove adapted to the sliding block, which can facilitate the sliding of the sliding block.

[0009] The temperature sensor is connected to the external electric control mechanism through the wires built into the rotating rod, the sliding block, the connecting rod and the rotating shaft, and can accurately measure the temperature in the stirring tank at multiple points.

[0010] The temperature sensor is semicircular, and the inner groove is a semicircular groove, which can increase the contact area for easy temperature detection and facilitate the inner groove to wipe the surface of the temperature sensor to maintain cleanliness.

[0011] A driving gear is fixedly connected to the surface of the rotating rod, and a driven gear meshing with the driving gear is fixedly connected to the surface of the fixed rod. When the sliding block drives the rotating rod to move in a circular direction, the driving gear meshes with the driven gear, driving the rotating rod to rotate, and driving the rubber pad to effectively wipe and clean each surface of the temperature sensor, thereby ensuring the cleanliness of the surface and preventing the temperature detection from being affected.

[0012] The rotating rods are provided with two and are symmetrically arranged on both sides of the rotating shaft. The fixing rods are provided with two and are symmetrically arranged on both sides of the rotating shaft.

[0013] The guide ring is arranged at the bottom conical section of the stirring tank and is located below the stirring assembly.

[0014] When in use, mix water and chemical fertilizers, then add them into the mixing tank and stir them through the stirring mechanism. When the stirring mechanism stirs, a clockwise water flow circulation will be formed in the mixing tank. At this time, the water flow drives the vortex plate to rotate, drives the rotating shaft to rotate clockwise, and drives the sliding block to rotate continuously on the guide ring through the connecting rod, drives the two temperature sensors to rotate continuously in the mixing tank to monitor the water temperature in various places. When the sliding block drives the rotating rod to move in a circular direction, the active gear meshes with the driven gear, drives the rotating rod to rotate, and effectively wipes and cleans each surface of the temperature sensor through the rubber pad to ensure the cleanliness of the surface and avoid the occurrence of accuracy problems in the sensor temperature detection.

[0015] Compared with the prior art, the present invention realizes multi-point temperature measurement of the sensor and cleans the surface of the temperature sensor at the same time, has a simple structure and low energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS
