Description

Technical Field

[0001] The present invention relates to the technical field of intelligent agricultural power machinery, and in particular to an integrated water and fertilizer machine. Background Art

[0002] Water-fertilizer integration is a modern agricultural technology that combines irrigation with fertilization. It sprays water and nutrients accurately and evenly to the crop growth area through a pipeline system, realizing the coordinated management of water and fertilizer, thereby supplying water and nutrients regularly and quantitatively according to the needs of the crop growth stage and improving resource utilization. With the advancement of planting technology, spraying hydrogen-rich water during the watering process has become more and more widely used in the agricultural field. It has the functions of eliminating free radicals, reducing oxidative damage, accelerating the germination and growth of seeds or seedlings, optimizing root development and nutrient absorption, enhancing photosynthesis and organic matter accumulation, optimizing soil microbial communities, and alleviating soil degradation and compaction. Chinese patent document CN219459763U discloses a water-fertilizer integrated hydrogen-rich water supplier, which provides stirring blades and scrapers on the stirring rod, not only using the stirring blades to achieve mixing of hydrogen-rich water and fertilizer, but also avoiding the adhesion of fertilizer to the inside of the supply cylinder, ensuring the full dissolution of fertilizer, providing balanced nutrition for agricultural irrigation and planting, but also facilitating the clearness of the supply cylinder and realizing the recycling of water bodies. Although the above-mentioned device can effectively mix hydrogen-rich water and fertilizer and promote the fusion between water and fertilizer, there are many insoluble solid particulate impurities in the fertilizer. During the irrigation process of the water-fertilizer integrated machine, drip irrigation or spraying is usually used. The insoluble solid particulate impurities easily flow with the water-fertilizer mixture to the drip irrigation head or nozzle, thereby causing the drip irrigation head or nozzle to clog, which not only reduces the uniformity of irrigation but also easily affects the irrigation efficiency. Therefore, the existing technology usually filters the fertilizer liquid entering the pipeline system after the water and fertilizer are mixed to filter out the insoluble solid particulate impurities in the fertilizer liquid to prevent them from clogging the pipeline. However, long-term filtration will cause a large amount of insoluble solid particulate impurities to be deposited on the filter screen, and even the insoluble solid particulate impurities will clog the mesh, requiring the machine to be stopped for cleaning, which is not only time-consuming and labor-intensive, but also affects the smoothness and efficiency of irrigation. Summary of the Invention

[0019] The present invention uses a water storage tank and a first conduit to fill a mixing tank with hydrogen-rich water. Solid fertilizer is added through a feed port. A stirring assembly disposed within the mixing tank achieves uniform stirring and mixing of the hydrogen-rich water and solid fertilizer, achieving a uniform ratio of fertilizer to hydrogen-rich water. After uniform mixing, a filter cartridge filters out water-insoluble solid particles from the water-fertilizer mixture, effectively preventing solid particles from flowing into the spray pipe and potentially clogging the water conduit or drip irrigation head, thereby ensuring efficient and uniform irrigation of the water and fertilizer solution. Furthermore, during the continuous stirring and filtering process, the diverter cartridge, piston assembly, opening and closing assembly, and drive assembly coordinate with the stirring assembly, enabling backwashing of the filter screen (i.e., the curved filter screen) during the continuous stirring process. This effectively prevents solid particle accumulation, filter screen clogging, and the need to stop the machine for cleaning, which can lead to cumbersome operation and low irrigation efficiency. The provision of a spray pipe allows for irrigation operations of varying densities, ensuring efficient operation, and offers greater adaptability and a wider range of applications.

Figure 4 As shown), the two auxiliary synchronization shafts 6344 respectively penetrate the corresponding side walls of the gear box 304 and are rotatably connected; the outer wall of the gear box 304 is connected to the inner wall of the mixing box 30 through the connecting bracket 303 (combined with Figure 3 and Figure 4 shown).

[0038] The side of the transfer box 40 away from the mixing box 30 is connected to the spray pipe 50 through the third conduit 41. The third conduit 41 is provided with a water pump for extracting water. The spray pipe 50 includes a water pipe 51 and a drip irrigation head 52 (such as Figure 10 As shown, the water pipe 51 is fixedly arranged on the end surface of the chassis 10 by a positioning bracket and the two ends of the water pipe 51 protrude from both sides of the chassis 10. The water pipe 51 is located at the bottom of both sides of the chassis 10 and multiple drip irrigation heads 52 are evenly arranged (as shown in FIG.

[0039] Example 2:

[0040] As another preferred embodiment of the present invention, based on the water-fertilizer integrated machine described in Example 1, in order to prevent the filter cylinder 61 and the diverter cylinder 62 from leaking during the sliding process of the piston rod 612 and the sliding rod 623, see Figure 2 As shown, a bellows is provided between the piston plate 611 and the inner cavity side wall of the filter cylinder 61 and located at the outer ring of the piston rod 612, and between the rubber stopper 622 and the inner cavity side wall of the diverter cylinder 62 and located at the outer ring of the sliding rod 623. The bellows are coaxially arranged with the corresponding piston rod 612 and sliding rod 623 (the two ends of the bellows are fixedly connected to the corresponding end face of the piston plate 611, the inner cavity side wall of the filter cylinder 61, the end face of the rubber stopper 622, and the inner cavity side wall of the diverter cylinder 62), so as to prevent liquid from leaking from the connection between the piston rod 612 and the filter cylinder 61, and the connection between the sliding rod 623 and the diverter cylinder 62.

[0041] Example 3:

[0042] As another preferred embodiment of the scheme of the present invention, on the basis of the water-fertilizer integrated machine described in Example 1, in order to ensure the stable sliding of the positioning pull plate 613, horizontal slide grooves are respectively provided on the upper and lower outer walls of the filter cylinder 61 and the horizontal slide grooves are parallel to the central axis of the filter cylinder 61. A limit slider is slidingly arranged in the horizontal slide groove and the side surface of the limit slider close to the positioning pull plate 613 is fixedly connected to the positioning link through a horizontal connecting rod.

[0043] Example 4:

[0044] As another preferred embodiment of the scheme of the present invention, on the basis of the water-fertilizer integrated machine described in Example 1, in order to avoid the problem of decreased solubility of hydrogen due to increased temperature during the stirring process, the outer wall of the mixing box 30 is wrapped with an insulation shell, and a circulating water cooling mechanism (for example: an assembly consisting of evenly wound water-cooling pipes and cooling devices) is arranged between the inner cavity of the insulation shell and the outer wall of the mixing box 30, thereby achieving low-temperature stirring and reducing the risk of hydrogen solubility escaping as the temperature increases.

[0045] Example 5:

[0046] As another preferred embodiment of the present invention, based on the water-fertilizer integrated machine described in Example 1, in order to prevent the fertilizer particles from adhering to the inner side wall of the mixing box 30 during the stirring process, a cleaning scraper is provided at one end of the stirring rod 38 in the same row away from the stirring shaft 31, thereby cleaning the side wall of the mixing box 30 in real time during the stirring process.

[0047] Example 6:

[0048] A method for integrated water and fertilizer irrigation containing hydrogen-rich water, using any one of the integrated water and fertilizer machines of Examples 1 to 5, comprising:

[0049] Step 1: First, the hydrogen-rich water in the water storage tank 20 is pumped into the inner cavity of the mixing tank 30 through the water pump on the first conduit 21; when the hydrogen-rich water in the mixing tank 30 reaches a specified liquid level (the liquid level of the hydrogen-rich water can be monitored in real time by setting a liquid level sensor in the mixing tank 30), mixed fertilizer is added through the feeding port 302. After adding a certain amount of mixed fertilizer, the feeding port 302 is closed with a sealing cover to prevent hydrogen from overflowing during the stirring process.

[0050] Step 2: Start the stirring shaft 31 to rotate. The stirring shaft 31 synchronously drives the upper gear 32, the lower gear 35, the stirring rod 38, the upper bevel gear 6341 and the lower bevel gear 6342 to rotate. The upper gear 32 drives the upper gear ring 34 to rotate through the upper connecting gear 33, and the lower gear 35 drives the lower gear ring 37 to rotate through the lower connecting gear 36, thereby realizing the rotation of the rotating bracket 340 of the upper gear ring 34 and the lower gear ring 37. The rotation of the rotating bracket 340 in the opposite direction to the rotation direction of the stirring rod 38 forms a composite rotation with the stirring rod 38 to improve the mixing uniformity between the solid fertilizer and the hydrogen-rich water;

[0051] The mixed fertilizer liquid passes through the arc filter 610 and enters the filter cylinder 61 and the diversion cylinder 62, and is blocked by the piston plate 611 in the filter cylinder 61 to the filter cylinder 61. Figure 2 The left side shown is blocked by the rubber stopper 622 to the left side of the diverter tube 62 (the rubber stopper 622 cooperates with the annular protrusion 621 to form a seal for the diverter tube 62);

[0052] As the stirring shaft 31 continues to rotate, the upper bevel gear 6341 and the lower bevel gear 6342 respectively drive the auxiliary transmission wheel 6345 to rotate through the corresponding transmission bevel gear 6343 and the auxiliary synchronization shaft 6344, and then the cam plate 631 is driven to rotate by the transmission chain 6346, the main transmission wheel 633 and the main synchronization shaft 632. The protruding part of the cam plate 631 gradually supports the corresponding bearing support 615, and pulls the positioning pull plate 613 to slide horizontally along the end away from the mixing box 30 (this During this process, the first spring 614 is stretched); at this time, the positioning pull plate 613 presses against the movable block 625, and the movable block 625 drives the sliding block 624 to follow the movement of the positioning pull plate 613 (during this process, the third spring 627 is stretched). The sliding block 624 pulls the rubber stopper 622 to the side away from the annular protrusion 621 through the sliding rod 623, thereby opening the middle through hole of the annular protrusion 621, so that the fertilizer liquid in the diversion cylinder 62 enters the interior of the transfer box 40 through the second conduit 620.

[0053] As the cam plate 631 continues to rotate, the positioning pull plate 613 and the sliding block 624 continue to move as shown in FIG. Figure 2 As shown in FIG1 , when the adjusting rods 6250 on both sides of the movable block 625 come into contact with the inclined surface structure of the corresponding adjusting block 43, the adjusting rods 6250 and the movable block move downward synchronously during the rightward movement due to the guidance of the inclined surface structure of the adjusting block 43 (during this process, the second spring 626 is compressed), thereby causing the top end of the movable block 625 to move downward to the lower side of the bottom end of the positioning pull plate 613 (as shown in FIG1 ). Figure 11 At this time, due to the elastic force of the third spring 627, the sliding block 624 moves rapidly toward Figure 11As shown, the rubber plug 622 is quickly moved to the left by the sliding rod 623, so that the rubber plug 622 can re-seal the annular protrusion 621. During this process, the protruding end of the cam plate 631 just contacts the side of the corresponding bearing support 615. As the cam plate 631 continues to rotate, the protruding portion of the cam plate 631 no longer presses against the bearing support 615. Due to the elastic force of the first spring 614, the positioning pull plate 613 is pulled as shown. Figure 11 As shown, the piston rod 612 and piston plate 611 push the fertilizer liquid in the filter cartridge 61 toward the inner cavity of the mixing box 30 (at this time, the diverter cartridge 62 is closed), flushing the curved filter screen 610 and preventing solid particles from clogging its mesh. As the positioning plate 613 continues to move left, the curved chamfered structure at the bottom of the positioning plate 613 presses against the inclined surface of the movable block 625, causing it to move downward again, thereby returning the positioning plate 613 to the left of the movable block 625.

[0054] The above cycle realizes the stirring and filtering of the fertilizer liquid and the repeated flushing of the curved filter screen 610.

[0055] Step 3: Control the movement of the entire integrated water and fertilizer machine by driving the rear wheel mechanism, and adjust the movement direction and the horizontality of the chassis 10 in real time through the front wheel mechanism (the horizontal state of the chassis can be monitored in real time by evenly arranging horizontal sensors on the end surface of the chassis 10, so as to achieve adjustment using the front wheel mechanism), so that the entire integrated water and fertilizer machine moves in the area to be irrigated; then, the fertilizer liquid in the transfer box 40 is pumped into the water pipe 51 through the water pump of the third conduit 41, and drip irrigation is achieved through the drip irrigation head 52.
