Description

Technical Field

[0001] The utility model relates to the technical field of agriculture, in particular to a water and fertilizer integration machine. Background Art

[0002] The water and fertilizer integration technology refers to a new agricultural technology that combines irrigation and fertilization. Water and fertilizer integration is to mix soluble solid or liquid fertilizers with irrigation water according to the soil nutrient content and the fertilizer requirement rules and characteristics of crop varieties. After the fertilizer solution and irrigation water are mixed, they are supplied with water and fertilizer through a controllable pipeline system. After the water and fertilizer are mixed, drip irrigation is formed through pipelines and drip heads, evenly, regularly, and quantitatively infiltrating the root development and growth area of crops.

[0003] The patent with the publication number of CN219660386U proposes a water and fertilizer integration machine. By adding solid fertilizer into the filtration tank to contact with the fertilizer solution, insoluble solid fertilizer is filtered out during the dissolution process of the solid fertilizer and the fertilizer solution, avoiding the blockage of the subsequent drip irrigation mechanism. However, when using this device, it is necessary to manually add solid fertilizer and fertilizer solution, so it is necessary to manually weigh the fertilizer solution and solid fertilizer each time, which is not simple and convenient to use. In addition, as the irrigation progresses, the liquid level of the fertilizer solution will drop. And since the filtration tank is located at the top of the machine, after the fertilizer solution drops for a certain period, the solid fertilizer in the filtration tank can no longer contact the fertilizer solution. Therefore, it is necessary to quickly dissolve the solid fertilizer in the fertilizer solution in a short time. If it cannot be completely dissolved, it will affect the actual mixing ratio of the waste water and the solid fertilizer. Therefore, further improvement is needed. Content of the Utility Model

[0023] A plurality of universal wheels 15 are installed on the lower surface of the bottom plate 1.

[0024] The quantitative feeding assembly 5 includes a material bucket 51 fixedly connected to the support rod 4. A feeding port is provided on the top wall of the material bucket 51. The bottom end of the material bucket 51 is fixedly connected to a feeding pipe 52. The bottom end of the feeding pipe 52 passes through the reserved opening 21 and extends into the mixing tank 2. A reduction motor 53 is fixed on the top wall of the material bucket 51. The bottom driving end of the reduction motor 53 is fixedly connected to a vertical shaft 54. A spiral conveyor 55 is fixedly connected to the surface of the bottom end of the vertical shaft 54. The spiral conveyor 55 is located inside the feeding pipe 52.

[0025] The material bucket 51 is used for storing solid fertilizer. By driving the spiral conveyor 55 to rotate in the feeding pipe 52 through the reduction motor 53, the solid fertilizer in the material bucket 51 can be discharged into the mixing tank 2 along the feeding pipe 52. The amount of reduction of the mixing tank 2 measured by the weighing scale 3 is the amount of solid fertilizer added to the mixing tank 2, thus realizing quantitative addition.

[0026] Solenoid valves are installed in the middle of the liquid inlet pipe 6 and the liquid discharge pipe 11. The solenoid valves, the reduction motor 53, the weighing scale 3, the driving motor 9 and the flow meter 7 are all electrically connected to the controller 10.

[0027] The solenoid valves can be controlled through the controller 10, and the solenoid valves, the reduction motor 53, the weighing scale 3, the driving motor 9 and the flow meter 7 operate in cooperation.

[0028] The crushing and mixing assembly 8 includes a driving shaft 81 that is sealingly and rotatably connected to the bottom wall of the mixing tank 2.

A plurality of stirring blades 83 are fixed on the surface of the bottom end of the driving shaft 81.

[0029] The driving motor 9 can drive the blade 82 and the stirring blades 83 to rotate. When the solid fertilizer enters the mixing tank 2 from the feeding pipe 52, the blade 82 will rotate at a high speed and break up the solid fertilizer.

During the drip irrigation process, the solid fertilizer in the mixing tank 2 is always stirred and in contact with the fertilizer solution to ensure the actual mixing ratio. When the filter screen 13 is blocked, the filter box 12 can be unscrewed from the drain pipe 11 and then flushed in the reverse direction to achieve the flushing of the filter screen 13.

[0032] A liquid level sensor 14 is fixedly installed on the inner side wall of the mixing tank 2, and the liquid level sensor 14 is electrically connected to the controller 10. A transparent viewing window 16 is fixed on the side wall of the mixing tank 2.

[0033] The liquid level of the fertilizer solution inside the mixing tank 2 can be known through both the viewing window 16 and the liquid level sensor 14.

[0034] Working principle: Connect the round tube at one end of the filter box 12 to the drip irrigation mechanism. Add the fertilizer solution to the mixing tank 2 through the liquid inlet pipe 6. During the addition process, it is measured by the flow meter 7. After the addition is completed, the solenoid valve on the liquid inlet pipe 6 is closed. Then, drive the auger 55 to rotate by the reduction motor 53, so that the solid fertilizer in the feed hopper 51 is added to the mixing tank 2. During the addition process, the drive motor 9 drives the blade 82 to rotate at a high speed, and the solid fertilizer is broken by the blade 82. After the solid fertilizer is mixed with the fertilizer solution, the mixing is accelerated by the stirring blade 83. After stirring for a period of time, open the solenoid valve on the drain pipe 11, so that the fertilizer solution is discharged along the drain pipe 11, and the filter screen 13 is used to block the undissolved solid fertilizer and impurities.
