Technical Field

[0001] The present application belongs to the technical field of agricultural equipment, and more specifically, relates to an integrated water and fertilizer treatment device. Background Art

[0002] In the process of agricultural production, it is often necessary to provide crops with sufficient and uniform water and fertilizer to promote crop growth and development.

[0003] In the related art, a common water-fertilizer treatment device is to mix water and fertilizer, and then transport the water and fertilizer to the crop area that needs fertilization through a pipeline. During the use of the water-fertilizer treatment device, there may be a situation where the water-soluble fertilizer particles are not completely dissolved; and after the water-fertilizer treatment device outputs the water and fertilizer, the incompletely dissolved fertilizer particles are prone to local accumulation in the soil, forming a local nutrient-rich area. This uneven growth environment will affect the absorption and growth of the crop root system, resulting in uneven crop growth. Utility Model Content

[0007] Through the above technical scheme conceived by the present application, compared with the prior art, since the device is provided with a filtering mechanism, after the water-fertilizer stirring mechanism stirs the water-fertilizer and supplies the water-fertilizer mixture to the filtering mechanism, the multi-stage filters in the filtering mechanism can intercept the undissolved fertilizer particles in the water-fertilizer mixture at multiple levels, so that the undissolved particles are intercepted in the filters at each level, and the undissolved fertilizer particles are separated from the solution to reduce the undissolved fertilizer particles in the output water-fertilizer. In addition, since the interception structure intercepts the undissolved fertilizer particles at the upper end of the filter, the undissolved fertilizer particles can be washed away in the process of the water-fertilizer mixture flowing through the filter step by step, which promotes the dissolution of the fertilizer particles.

[0017] By adopting the above technical solution, the provided reinforcement ring is connected to the stirring blade, thereby ensuring the connection reliability of the stirring blade.

[0018] As a further preference, the frame is also provided with a primary filtering mechanism for supplying clean water to the water-fertilizer mixing mechanism.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] The following is combined with Figure 1-5 This application is described in further detail.

[0040] The present application embodiment discloses an integrated water and fertilizer treatment device. Figure 1 The integrated water-fertilizer treatment device includes a frame 1, on which a filtering mechanism and a water-fertilizer stirring mechanism are arranged. The water-fertilizer stirring mechanism can mix and stir water and fertilizer, and supply the stirred water-fertilizer mixture to the filtering mechanism; the filtering mechanism can perform multi-stage filtration on the water-fertilizer mixture. Specifically, the filtering mechanism includes a plurality of filters 2 that are connected in sequence and arranged step by step, and the lower end of the filter 2 at the upper level is connected to the upper end of the adjacent lower-level filter 2; in addition, the internal upper ends of the plurality of filters 2 are all provided with interception structures, and the interception particle sizes of the plurality of interception structures decrease step by step along the flow direction of the water-fertilizer mixture.

[0041] Further, in this embodiment, a plurality of pulleys 1-1 are provided at the bottom of the frame 1, and a handle 1-2 is provided on one side of the frame 1. Preferably, four pulleys 1-1 are provided, and are distributed at the four corners of the bottom of the frame 1. By providing the pulleys 1-1, the device can be quickly transferred, and irrigation in different areas can be conveniently implemented.

[0042] Furthermore, the frame 1 is also provided with a photovoltaic mechanism for providing electric energy and a primary filtering mechanism for supplying water to the water-fertilizer mixing mechanism. The photovoltaic mechanism can convert solar energy into electric energy for the operation of other power-consuming parts in the supply device, which is conducive to the use of the device in remote areas where there is a lack of power supply or the length of the power cable of the external power supply is not enough. The primary filtering mechanism can supply clean water to the water-fertilizer mixing mechanism and filter out insoluble impurities and other substances in the water source.

[0043] Specifically, if Figure 1 As shown, the photovoltaic mechanism includes a solar panel 3 and a battery. In this embodiment, the solar panel 3 is connected to the frame 1 through four telescopic rods 4 that can be adjusted and retracted, so that the solar panel 3 can be installed on the frame 1 in a lifting and adjusting manner. The upper ends of the solar panel 3 and the telescopic rods 4 are preferably connected by rotation. The telescopic rod 4 is a prior art, and an electric telescopic rod or a manual telescopic rod can be used, as long as the lifting and lowering adjustment of the solar panel 3 can be achieved. In other embodiments, the solar panel 3 can also be connected to the frame 1 through an adjustable displacement structure, and the solar panel 3 can be turned over, lifted, and moved horizontally on the frame 1 by adjusting the displacement structure. Further, the electric energy generated by the solar panel 3 is stored in the battery, and the battery can supply direct current to the remaining power structures (such as motors, water pumps, etc.) in the device, or be converted into alternating current by an inverter for power supply. In some embodiments, in order to improve the power generation efficiency of the device, the photovoltaic mechanism includes a plurality of solar panels 3, and the plurality of solar panels 3 can be folded.

[0044] Further, such as Figure 2 As shown, in order to provide relatively clean water to the water-fertilizer mixing mechanism, the primary filtration mechanism includes a filter barrel 5, in which a filter medium layer is arranged, and the filter medium layer is composed of quartz sand, quartz gravel, etc.; the upper end of the filter barrel 5 is a bolted cover to facilitate the inspection and maintenance of the filter cartridge 5.

[0045] In addition, the upper end of the filter barrel 5 is connected to a water inlet pipe 6, on which a water pump 7 is installed, and the water pump 7 is electrically connected to the photovoltaic mechanism. The lower end of the filter barrel 5 is connected to a water outlet pipe 8, which is connected to the water-fertilizer mixing mechanism.

[0046] When in use, the water pump 7 draws water from an external source through the water inlet pipe 6 and pumps the water into the filter barrel 5. The drawn water is first coarsely filtered through the filter medium layer to filter out insoluble impurities and other substances in the water source. The filtered water is then sent to the water-fertilizer mixing mechanism through the water outlet pipe 8, and the water-fertilizer mixing mechanism mixes water and fertilizer.

[0047] Further, such as Figure 3-4As shown, in order to mix water and fertilizer, the water-fertilizer mixing mechanism includes a mixing box 9 and a mixing assembly installed on the mixing box 9 for mixing water and fertilizer. The upper end of the mixing box 9 is open, and the mixing box 9 is connected to the filter barrel 5 through the outlet pipe 8 mentioned above. A feeding pipe 10 is connected between the mixing box 9 and the filtering mechanism, and another water pump 7 and a shut-off valve 19 for switching the feeding pipe 10 are also connected to the feeding pipe 10, so that the feeding pipe 10 can be used to supply the water-fertilizer mixture to the filtering mechanism.

[0048] Furthermore, a transmission box 17 is fixed to the upper end of the mixing box 9, and the mixing assembly is mounted in the mixing box 9 through the transmission box 17. The mixing assembly includes a mixing shaft 11 and a power part for driving the mixing shaft 11 to rotate.

[0049] Specifically, the upper end of the stirring shaft 11 is rotatably mounted on the transmission box 17 in the axial direction through a bearing or other rotating connection. The circumferential side of the stirring shaft 11 is connected to a plurality of reinforcement rings 12 through a connecting rod, and a plurality of stirring blades 13 are circumferentially connected to the reinforcement ring 12. When in use, the power member drives the stirring shaft 11 to rotate, so that the stirring shaft 11 with the stirring blades 13 stirs and mixes the materials in the stirring box 9. Then the water-fertilizer mixture produced can be pumped to the filtering mechanism along the feeding pipe 10.

[0050] In this embodiment, the power part includes a motor, which can be electrically connected to the photovoltaic mechanism, and the motor drives the stirring shaft 11 to rotate through a transmission structure; the motor is a prior art and is not shown in the figure. In addition, the transmission structure is preferably a gear transmission structure 14; for example, the gear transmission structure 14 includes two mutually meshing transmission gears, one transmission gear is coaxially connected to the stirring shaft 11, and the other transmission gear is coaxially connected to the output shaft of the motor; in other embodiments, the output shaft of the motor directly drives the stirring shaft 11 to rotate through a coupling, or drives the stirring shaft 11 to rotate through a belt drive, a chain drive or other structures.

[0051] After the stirring assembly completes the stirring of the water and fertilizer in the stirring box 9, the water-fertilizer mixture is pumped into the filter 2 of the filtering mechanism by the feeding pipe 10; in order to smoothly perform multi-stage filtration of the water-fertilizer mixture, the filtering mechanism also includes a connecting pipe, which includes a plurality of connecting sections 15 connected in series in sequence, and adjacent connecting sections 15 are detachably connected through a detachable connecting structure; in some embodiments, the feeding pipe 10 for connecting the stirring box 9 and the filtering mechanism can also be composed of a plurality of connecting sections 15 connected in series in sequence, and in some embodiments, a shut-off valve 19 can also be installed on the connecting pipe between two adjacent filters 2. In addition, when necessary, some connecting sections 15 can be hoses.

[0052] Specifically, the detachable connection structure between the connection sections 15 includes but is not limited to flanges, ferrules, clamps, quick-connect joints, etc., as long as the detachable installation between adjacent connection sections 15 can be achieved. In this embodiment, the upper end of the uppermost filter 2 is connected to the mixing box 9 through the feed pipe 10, the upper filter 2 is connected to the adjacent lower filter 2 through a connecting pipe, and the lower end of the lowermost filter 2 (i.e., the filter 2 that finally receives the water-fertilizer mixture) is connected to a discharge pipe 16, which is used to enter the drip system through an external drip interface to irrigate crops.

[0053] Further, such as Figure 5 As shown, the filter 2 includes a water storage cylinder 2-1 and a supporting cylinder 2-2, the supporting cylinder 2-2 is connected to the upper end of the water storage cylinder 2-1, and the diameter of the supporting cylinder 2-2 is smaller than the diameter of the water storage cylinder 2-1, and the water storage cylinder 2-1 and the supporting cylinder 2-2 form a water storage structure with a small upper end and a large lower end. The interception structure includes but is not limited to a filter screen, a filter cylinder 2-3 or a filter plate, etc., as long as it can filter the water flowing between the water storage cylinder 2-1 and the supporting cylinder 2-2.

[0054] In this embodiment, the interception structure is selected as a filter cartridge 2-3, the upper end of the filter cartridge 2-3 is provided with an opening, and the upper circumferential edge of the filter cartridge 2-3 protrudes to form a flange; the lower circumferential surface and the bottom surface of the filter cartridge 2-3 are distributed with a plurality of filter holes. Correspondingly, the inner wall of the upper end of the filter cartridge 2-3 protrudes circumferentially to form a limit plate 2-4, and the filter cartridge 2-3 can be carried and supported in the filter cartridge 2-3 by the limit plate 2-4. It should be noted that the mesh aperture of the filter cartridge 2-3 in each level of filter 2 is gradually reduced along the flow path of the water-fertilizer mixture so that the water and fertilizer can be filtered in multiple stages.

[0055] Furthermore, in this embodiment, an inspection port 2-5 is provided at the upper end of the carrier tube 2-2, and a cover plate 18 is welded, threaded, or snap-connected to the outer end of the connecting section 15 adjacent to the inspection port 2-5; in this design, the connecting section 15 adjacent to the carrier tube 2-2 is connected to the carrier tube 2-2 through the inspection port 2-5, and the liquid outlet of the connecting section 15 faces the inner cavity of the filter cartridge 2-3 in the carrier tube 2-2. The cover plate 18 on the connecting tube covers the inspection port 2-5 of the carrier tube 2-2, and the cover plate 18 and the inspection port 2-5 are sealed by a sealing strip.

[0056] In some embodiments, the cover plate 18 can directly cover the outer end surface of the bearing tube 2-2 through a sealing strip, or the cover plate 18 can also be detachably connected to the bearing tube 2-2 through a flange connection or a clamp connection. Of course, in some embodiments, the interception structure can be selected as a flexible filter screen fixed to the limit plate 2-4 by bolts, and the side wall of the bearing tube 2-2 can be opened and closed with an inspection door, and the filter screen can be directly cleaned or replaced by opening the inspection door.
