Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation and fertilization technology, specifically a water and fertilizer integration system for facility agriculture. Background Technology

[0002] Agriculture is an important foundation of my country's national economy. Traditional irrigation methods involve drawing water from the surface to moisten the soil in the fields. When fertilizing crops, fertilizer is spread manually and then irrigated to allow the fertilizer to dissolve and seep into the soil for the crops to absorb. However, traditional irrigation and fertilization methods not only cause serious waste of water resources but also lead to uneven fertilization and fertilizer waste. Fertilizer and water integration utilizes pressure systems or natural terrain gradients to mix soluble solid or liquid fertilizers with irrigation water. The fertilizer solution, formulated according to soil nutrient content and crop nutrient requirements, is delivered through a controlled pipeline system. This allows the water and fertilizer to blend and then drip-irrigate the crop's root zone evenly, regularly, and quantitatively, maintaining loose and suitable soil moisture for the main root system. However, existing fertigation systems often use groundwater. As the groundwater source deepens, the water temperature decreases, making it difficult to mix the added fertilizer evenly and potentially causing sedimentation. Furthermore, the depth makes it difficult to monitor fertilizer dissolution in the fertilizer tank. This leads to uneven fertilizer dissolution in the irrigation unit, resulting in inconsistent plant growth, pipe blockage, and increased management costs. Therefore, there is a need to develop a facility agriculture fertigation system that can balance irrigation water temperature and improve fertilizer solubility. Utility Model Content

[0003] To address the above technical problems, this utility model provides a facility agriculture water and fertilizer integration system that can balance irrigation water temperature and improve fertilizer solubility. This solves the problems of low groundwater temperature reducing fertilizer solubility and even causing precipitation, as well as difficulty in confirming fertilizer dissolution in fertilizer tanks due to water depth, resulting in uneven plant growth and development in irrigation units, pipe blockage, and increased management costs.

[0004] To solve the above-mentioned technical problems, the present invention provides a facility agriculture water and fertilizer integration system, comprising a fertilizer tank, a pulsator rotatably connected to the bottom inner side of the fertilizer tank, the pulsator being driven by a pulsator motor, a dissolving tank fixedly connected to the top inner side of the fertilizer tank, the dissolving tank having several through holes, an auger conveyor and a stirring motor fixedly connected to the top outer side of the fertilizer tank, the output end of the auger conveyor extending through the top of the fertilizer tank into the interior of the dissolving tank, a stirring shaft extending into the dissolving tank fixedly connected to the output end of the stirring motor, stirring blades fixedly connected to the stirring shaft, a water inlet pipe fixedly connected to one side of the upper part of the fertilizer tank, a discharge pipe fixedly connected to one side of the lower part, and an insulation layer fixedly connected to the outer side of the fertilizer tank.

[0005] Furthermore, the impeller motor and the reduction clutch are fixedly connected to the bottom of the outer side of the fertilizer tank. The impeller is rotatably connected to the bottom of the fertilizer tank through the impeller shaft. The impeller shaft is fixedly connected to the output end of the reduction clutch. A driven wheel is fixedly connected to the input end of the reduction clutch. A driving wheel is fixedly connected to the output end of the impeller motor. The driving wheel and the driven wheel are connected by belt drive.

[0006] Furthermore, the insulation layer includes an insulation shell and a heating rod. The insulation shell is fixedly connected to the outside of the fertilizer tank, and the heating rod is embedded inside the insulation shell.

[0007] Furthermore, a protective shell located outside the reduction clutch and impeller motor is fixedly connected to the bottom of the fertilizer tank, and a support foot is fixedly connected to the bottom of the protective shell.

[0008] Furthermore, a water level monitoring gauge is fixedly connected to the upper part of the fertilizer tank.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] This invention utilizes a dissolving tank, along with a matching stirring shaft and blades, to perform the initial dissolution of fertilizer. The initially dissolved fertilizer then flows downwards into the fertilizer tank through a through-hole. A secondary dissolution is achieved by incorporating a pulsator, pulsator motor, and reduction clutch, preventing the fertilizer from settling due to incomplete dissolution. An insulation layer is installed outside the fertilizer tank, and a heating rod within the insulation layer heats the contents of the fertilizer tank. The insulation shell reduces heat exchange between the contents of the fertilizer tank and the air, maintaining the liquid within the fertilizer tank at a suitable temperature range and preventing incomplete dissolution due to excessively low solute temperature.

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1The illustrated integrated water and fertilizer system for facility agriculture includes a fertilizer tank 1. A pulsator 16 is rotatably connected to the bottom inner side of the fertilizer tank 1, and the pulsator 16 is driven by a pulsator motor 10. To ensure complete dissolution of the fertilizer, a dissolving tank 4 is fixedly connected to the top inner side of the fertilizer tank 1. The dissolving tank 4 has several through holes 9. An auger conveyor 5 and a stirring motor 6 are fixedly connected to the top outer side of the fertilizer tank 1. To prevent splashing when the fertilizer enters the water and to prevent certain substances in the fertilizer from floating on the surface of the solute and causing incomplete dissolution, the output end of the auger conveyor 5 extends through the top of the fertilizer tank 1 into the interior of the dissolving tank 4. A stirring shaft 7 extending into the dissolving tank 4 is fixedly connected to the output end of the stirring motor 6. A stirring blade 8 is fixedly connected to the stirring shaft 7. A water inlet pipe 2 is fixedly connected to one side of the upper part of the fertilizer tank 1, and a discharge pipe 3 is fixedly connected to one side of the lower part. To ensure that the temperature of the contents of the fertilizer tank 1 is consistent with the surface temperature, an insulation layer 21 is fixedly connected to the outer side of the fertilizer tank 1.

[0015] It should be noted that the auger conveyor device 5 in this utility model is an existing device, mainly composed of a trough, a screw shaft, bearings and other structures. Its specific structure will not be described in detail in this article.

[0016] In order to fully dissolve the fertilizer in the fertilizer tank 1 and prevent certain substances in the fertilizer from settling and accumulating, a pulsator motor 10 and a reduction clutch 11 are fixedly connected to the bottom of the outer side of the fertilizer tank 1. The pulsator 16 is rotatably connected to the bottom of the fertilizer tank 1 through the pulsator shaft 15. The pulsator shaft 15 is fixedly connected to the output end of the reduction clutch 11. The driven wheel 12 is fixedly connected to the input end of the reduction clutch 11. The driving wheel 13 is fixedly connected to the output end of the pulsator motor 10. The driving wheel 13 and the driven wheel 12 are connected by a belt 14.

[0017] In order to avoid the fertilizer being difficult to dissolve due to the low temperature of the solute, and the plant roots being hindered from growing due to the rapid drop in ambient temperature, the insulation layer 21 includes an insulation shell and a heating rod. The insulation shell is fixedly connected to the outside of the fertilizer tank 1, and the heating rod is embedded in the insulation shell.

[0018] In order to protect the drive impeller 16 and increase the stability of the device, a protective shell 19 is fixedly connected to the bottom of the fertilizer tank 1, located outside the reduction clutch 11 and the impeller motor 10. A support foot 18 is fixedly connected to the bottom of the protective shell 19.

[0019] In order to monitor the liquid level in fertilizer tank 1 in real time, a water level monitoring meter is fixedly connected to the upper part of fertilizer tank 1.

[0020] The working process of this embodiment is as follows:

[0021] During use, water enters the fertilizer tank 1 through the inlet pipe. The water level is monitored by the water level gauge 20. After sufficient water is introduced, the fertilizer to be dissolved enters the dissolving tank 4 through the auger conveyor 5. The stirring motor 6 controls the rotation of the stirring shaft 7 and stirring blades 8 to accelerate the dissolution of the fertilizer. The dissolved fertilizer flows downwards into the fertilizer tank 1 through the through hole 9. The impeller motor 10 controls the rotation of the drive wheel 13, which drives the driven wheel 12 through the belt 14. Under the action of the reduction clutch 11, the speed of the impeller motor 10 is reduced and the torque is increased, driving the impeller 16 to work, making the liquid in the fertilizer tank 1 rotate. This performs a second stirring and dissolution of the fertilizer while preventing the precipitation of certain substances in the fertilizer. After stirring, the fertilizer is transported to the farmland through the discharge pipe 3. During the stirring process, in order to make the temperature of the contents of the fertilizer tank 1 consistent with the surface temperature, heating can be achieved by heating rods in the insulation layer 17. The insulation shell retains the temperature inside the fertilizer tank 1, reducing heat exchange with the air.
