Description

Technical Field

[0001] The utility model relates to the field of water and fertilizer integrators, and more specifically, to an agricultural fertilization and irrigation integrated device. 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 types by means of a pressure system (or natural terrain drop), and supply water and fertilizer through a controllable pipeline system, so that after the water and fertilizer are fused, drip irrigation is formed through pipelines and drip heads, evenly, regularly and quantitatively infiltrating the root development and growth area of crops.

[0003] In order to reduce the risk of blockage in the corresponding fertilization pipeline of the water and fertilizer integrator, a filter is generally provided on the water and fertilizer integrator to filter out undissolved fertilizer particles, including a disc filter. Although the existing disc filter has a good filtering and anti-blocking effect, the adjacent filter discs are usually closely fitted, and there is a lack of corresponding brushing structure on the outer surface, which is not conducive to quickly and smoothly flushing away the residual particles during backwashing. Therefore, we propose an agricultural fertilization and irrigation integrated device to solve the above problems. Content of the Utility Model

A sealing plug cover 8 is fixedly installed on the third water inlet interface. The water inlet end of the water pump 4 is connected to the bottom of the water tank 2 through a first connecting pipe 9. A second connecting pipe 10 and a third connecting pipe 11 are respectively fixedly connected to the first water inlet interface and the second water inlet interface. The other ends of the second connecting pipe 10 and the third connecting pipe 11 are connected through a fourth connecting pipe 12, and the fourth connecting pipe 12 is connected to the water outlet end of the water pump 4. A sewage discharge pipe 13 and a drain pipe 14 are respectively fixedly connected to the bottom of the filter housing 6. Control valves one 15 are fixedly installed on the second connecting pipe 10 and the third connecting pipe 11, and a control valve two 16 is fixedly installed on the sewage discharge pipe 13.

[0029] The working principle of this agricultural fertilization and irrigation integrated device is as follows:

[0030] When fertilization and irrigation are required, first pour granular or powdered fertilizer into the water tank 2 and add water to stir and mix. Then close the control valve two 16 and the control valve one 15 on the third connecting pipe 11, and open the control valve one 15 on the second connecting pipe 10. At this time, the water pump 4 can be started through the control box 3, and the liquid fertilizer stirred and mixed in the water tank 2 is pumped into the filter housing 6 through the first connecting pipe 9, the fourth connecting pipe 12, the second connecting pipe 10, and the first water inlet interface. At this time, the liquid fertilizer passes through the filter mesh cloth 19 inside the filter housing 6 and enters the communicating pipe 17 through the water permeable holes 1801 and the through holes 1701, and then is discharged through the drain pipe 14 connected to the communicating pipe 17, so as to conveniently reach each irrigation pipeline previously connected to the end of the drain pipe 14, achieving the effect of fertilization and irrigation;

[0031] When the inside of the filter 5 needs to be cleaned, first add clean water to the water tank 2, then open the control valve two 16 and the control valve one 15 on the third connecting pipe 11, and close the control valve one 15 on the second connecting pipe 10. The water is pumped into the filter housing 6 through the first connecting pipe 9, the fourth connecting pipe 12, the third connecting pipe 11, and the second water inlet interface under the drive of the water pump 4, and impacts the turbine blades 21 at the position of the second water inlet interface to make it rotate, and then drives the cleaning rods 23 on a group of square rods 22 to rotate, so as to brush the filter mesh cloth 19 on each hollow disc 18 through the bristles, improving the cleaning efficiency. The cleaning water can be directly discharged through the sewage discharge pipe 13.

[0032] Embodiment 2:

[0033] In view of the above Embodiment 1, for further description, refer to Figure 3 and Figure 4, at the bottom of the inner wall of the filter housing 6 located at the position of the drain pipe 14, a communicating pipe 17 is fixedly installed. A number of communicating holes 1701 are formed on the outer wall of the communicating pipe 17. A hollow disc 18 is fixedly connected to the outer wall of the communicating pipe 17 corresponding to the position of the communicating holes 1701. A number of water permeable holes 1801 are formed on the hollow disc 18. The outside of the hollow disc 18 is communicated with the inside of the communicating pipe 17 through the water permeable holes 1801 and the communicating holes 1701. A filter mesh cloth 19 is fixedly sleeved on the outer surface of the hollow disc 18. At the bottom of the upper cover 7 located at the position of the second water inlet interface, a cross-shaped bracket 20 is fixedly connected. The top of the cross-shaped bracket 20 is rotatably connected with a turbine blade 21 through a rotating shaft, and the bottom of the rotating shaft penetrates to the bottom of the cross-shaped bracket 20.

A brush is fixedly connected to the outer wall of the cleaning rod 23, and the brush is in contact with the outer wall of the corresponding filter mesh cloth 19.

[0034] The arrangement of the communicating pipe 17 facilitates the introduction of the filtered liquid fertilizer into the drain pipe 14 through the filter mesh cloth 19 and the hollow disc 18. The arrangement of the cross-shaped bracket 20 neither hinders the rotational installation of the rotating shaft nor hinders the normal flow of water. The turbine blade 21 can provide driving force for the rotation of a group of square rods 22.

[0035] The above is only the preferred specific implementation manner of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes an equivalent replacement or change, and should be covered by the protection scope of the present utility model.
