Description

Technical Field

[0001] This utility model relates to the field of water and fertilizer mixing technology for pomelo cultivation, and in particular to a water and fertilizer mixing device for pomelo cultivation. Background Technology

[0002] In pomelo cultivation, water and fertilizer management is a crucial aspect, but traditional methods suffer from low efficiency and resource waste. Water and fertilizer mixing devices have emerged to address this issue. By precisely controlling the water-to-fertilizer ratio, they achieve uniform irrigation and improve nutrient absorption efficiency. This device combines modern irrigation technology, reducing manual operation and labor intensity while avoiding environmental pollution caused by over-fertilization. Its intelligent design automatically adjusts according to soil moisture and the pomelo's growth needs, ensuring healthy crop growth and improving yield and quality, making it an ideal choice for efficient management in modern agriculture.

[0003] Currently, common water and fertilizer mixing devices for pomelo cultivation on the market have certain technical defects in the fertilizer mixing process, especially during fertilizer feeding. Because fertilizer contains various impurities (such as stones and sand), these impurities increase flow speed and pressure during feeding, leading to blockages in the fertilizer pipes or poor water flow. This phenomenon not only reduces irrigation efficiency but may also result in uneven fertilizer mixing, thus affecting the normal growth and yield of the pomelo.

[0004] In response to this technical problem, this application proposes a water and fertilizer mixing device for pomelo cultivation. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water and fertilizer mixing device for pomelo cultivation. This device effectively avoids the problem of blockage in the discharge pipe that may be caused by undissolved impurities in the fertilizer flowing into the irrigation system with the mixed liquid, ensuring continuous and stable water and fertilizer integrated irrigation operations, guaranteeing timely and sufficient precise nutrient supply to pomelo trees, improving the fertilization efficiency of pomelo cultivation, and meeting the needs of precision fertilization.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A water and fertilizer mixing device for pomelo cultivation includes a mixing chamber. A discharge pipe is fixedly connected to and passes through the front end of the mixing chamber. A fixing ring is fixedly connected to the inner wall of the discharge pipe. A drive motor is fixedly connected to the bottom end of the mixing chamber. The drive end of the drive motor is connected to a connecting frame and a transmission rod through a stirring assembly. A discharge chamber is installed on the outer wall of the top of the fixing ring. Several filter screens are fixedly connected to the outer wall of the discharge chamber. The left and right ends of the discharge chamber are connected to locking blocks through an installation assembly.

[0008] Furthermore, the stirring assembly includes a first bevel gear fixedly connected to the drive end of the drive motor, and a second bevel gear fixedly connected to both the connecting frame and the bottom end of the transmission rod. The first bevel gear and the second bevel gear are meshed together.

[0009] Furthermore, a connecting shell is fixedly connected to the inner wall of the discharge hopper, and an inner stirring frame is rotatably connected to the top of the connecting shell.

[0010] Furthermore, a splined shaft is fixedly connected to the bottom end of the inner stirring rack, a mating groove is provided at the top end of the transmission rod, and the bottom end of the splined shaft is installed on the inner wall of the mating groove at the transmission rod.

[0011] Furthermore, both ends of the connecting frame are fixedly connected to an outer stirring plate, and the outer wall of the outer stirring plate is in close contact with the inner wall of the mixing chamber.

[0012] Furthermore, the installation assembly includes fixed pipes fixedly connected to both ends of the discharge hopper, with the bottom ends of the fixed pipes installed on the inner walls of both ends of the fixed ring.

[0013] Furthermore, a fixing screw is threaded to the top end of the fixing tube, and a splined shaft is fixedly connected to the bottom end of the fixing screw.

[0014] Furthermore, each of the locking blocks is fixedly connected to a return spring at one end, and the opposite end of the locking block is in close contact with the bottom end of the spline shaft.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, during installation, the transmission rod connects with the splined shaft inside the connecting housing. The drive motor is started to drive the first bevel gear to rotate, which in turn drives the second bevel gear, causing the connecting frame and transmission rod to rotate. The transmission rod drives the splined shaft, which in turn drives the inner mixing frame to rotate, stirring the fertilizer and pre-added water in the discharge bin, promoting fertilizer dissolution. The dissolved mixture permeates through the filter screen into the mixing bin, while impurities remain in the discharge bin. The rotation of the connecting frame further stirs the fertilizer in the mixing bin, ensuring uniform mixing. This device achieves efficient water and fertilizer mixing and filtration, preventing impurities from clogging the discharge pipe, ensuring the normal operation of the irrigation system, and improving the fertilization efficiency of pomelo cultivation.

[0017] 2. In this utility model, after the fertilizer is put into the feeding bin, the fixing pipe is connected to the fixing ring, the fixing screw is rotated, and the spline shaft is driven to squeeze the card block to pop out and securely lock the feeding bin. When the fixing screw is rotated in the opposite direction, the reset spring causes the card block to retract, and the feeding bin is easily disassembled. This design simplifies the fertilizer feeding process, ensures stable operation of the device, facilitates quick fertilizer replacement, improves the fertilization efficiency of pomelo planting, and meets the needs of precision fertilization.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1-3This utility model provides an embodiment of a water and fertilizer mixing device for pomelo cultivation, comprising a mixing chamber 1, a discharge pipe 2 fixedly connected to the front end of the mixing chamber 1 and passing through it, a fixing ring 3 fixedly connected to the inner wall of the discharge pipe 2, a drive motor 9 fixedly connected to the bottom end of the mixing chamber 1, a connecting frame 5 and a transmission rod 6 connected to the drive end of the drive motor 9 via a stirring assembly, a discharge chamber 4 installed on the outer wall of the top of the fixing ring 3, the stirring assembly including a bevel gear 10 fixedly connected to the drive end of the drive motor 9, bevel gears 11 fixedly connected to the bottom ends of both the connecting frame 5 and the transmission rod 6, the bevel gears 10 and 11 being meshed, a connecting shell 14 fixedly connected to the inner wall of the discharge chamber 4, an inner stirring frame 8 rotatably connected to the top of the connecting shell 14, a splined shaft 15 fixedly connected to the bottom end of the inner stirring frame 8, a fitting groove opened at the top end of the transmission rod 6, the bottom end of the splined shaft 15 being installed on the inner wall of the fitting groove at the transmission rod 6, and outer stirring plates 7 fixedly connected to both ends of the connecting frame 5, the outer wall of the outer stirring plate 7 being tightly attached to the inner wall of the mixing chamber 1.

[0028] Specifically, in the installation and operation of the water and fertilizer mixing device for pomelo cultivation, one of the core steps is to ensure that the transmission rod 6 is precisely aligned with the splined shaft 15 nested inside the connecting shell 14. When the device is started, the drive motor 9 operates, first driving the bevel gear 10 connected to it to rotate; the bevel gear 10 then meshes and drives the bevel gear 11, which is designed in pairs with it, to rotate as well. This transmission action effectively transmits power to the connecting frame 5 and the transmission rod 6 fixedly connected to it through mechanical connection, causing them to rotate together. The rotation of the transmission rod 6 directly drives the splined shaft 15 connected to it to rotate synchronously, thereby driving the inner stirring frame 8 built into the bottom of the feeding bin 4 to start working. The rotation of the inner stirring frame 8 performs preliminary strong stirring and mixing of the fertilizer granules pre-added to the feeding bin 4 and the introduced water source, promoting the rapid and complete dissolution of the fertilizer to form a preliminary water and fertilizer mixture. The dissolved liquid fertilizer mixture is then permeated and screened by the filter screen set at the bottom of the feeding bin 4 under the action of gravity. The mixture enters the lower mixing chamber 1, while undissolved or larger impurity particles are effectively blocked and retained in the discharge chamber 4. At the same time, as the connecting frame 5 rotates as a whole, it directly and continuously stirs the water-fertilizer mixture in the mixing chamber 1. This not only ensures a more uniform distribution of the components in the mixture and prevents local concentrations from being too high or too low, but also further promotes the solubility and stability of the fertilizer. Through the series action of material dissolution, filtration and stirring of the mixture in the mixing chamber 1 achieved by the connecting frame 5 driving the inner stirring frame 8, the device efficiently completes the dual tasks of uniform mixing of water-fertilizer solution and impurity filtration. This not only significantly improves the preparation and mixing efficiency of water and fertilizer required for pomelo planting, but more importantly, it effectively avoids the problem of blockage of discharge pipe 2 caused by undissolved impurities in fertilizer (especially some organic or compound fertilizer components that are prone to caking) flowing into the irrigation system with the mixture. This ensures continuous and stable water and fertilizer integrated irrigation operations and guarantees that pomelo trees receive timely and sufficient precise nutrient supply.

[0029] Reference Figures 4-5 Several filter screens are fixedly connected to the outer wall of the discharge bin 4. The left and right ends of the discharge bin 4 are connected to the locking blocks 17 through the installation assembly. The installation assembly includes a fixing pipe 12 fixedly connected to both ends of the discharge bin 4. The bottom end of the fixing pipe 12 is installed on the inner wall of the left and right ends of the fixing ring 3. The top end of the fixing pipe 12 is threadedly connected to the fixing screw 13. The bottom end of the fixing screw 13 is fixedly connected to the spline shaft 15. The opposite end of the locking block 17 is fixedly connected to the return spring 16. The opposite end of the locking block 17 is tightly attached to the bottom end of the spline shaft 15.

[0030] Specifically, in the operation of the water and fertilizer mixing device for pomelo cultivation, after the fertilizer is added to the feeding hopper 4, the key fixing step is to precisely insert the fixing tube 12 extending from the upper end of the feeding hopper 4 into the fixing ring 3 pre-installed on the top of the mixing hopper 1, making vertical contact with it. To complete the locking, the operator then rotates the fixing screw 13. This screw moves axially through the spiral pattern matching the inner wall of the fixing tube 12. During the rotation, the fixing screw 13 pushes inward, and its end abuts against and drives the spline shaft 15 inside the feeding hopper 4 to move downward. The downward movement of the spline shaft 15 directly forms a vertical downward squeeze on the locking block 17 arranged at its bottom or side. Under the action of the squeezing force, the locking block 17 overcomes the initial restraint (possibly through an inclined plane or slider mechanism) and pops out radially, so that its end is firmly locked or embedded in the support structure or flange inside the bottom of the fixing ring 3, thereby forming a mechanical interlock and firmly locking the feeding hopper 4 in place. Its working position effectively prevents it from vibrating and loosening during mixing or equipment operation. When it is necessary to disassemble the discharge bin 4 for feeding or maintenance (especially when the fertilizer type needs to be changed frequently or residue needs to be cleaned at different growth stages of pomelo), simply rotate the fixing screw 13 in the opposite direction to make it rotate back and away from the spline shaft 15. At this time, the previously compressed return spring 16 will push the locking block 17 to retract radially towards the center due to its inherent elastic restoring force, so that it is released from the locking state with the fixing ring 3 or the support structure. Once the locking block 17 is fully retracted and reset, the entire discharge bin 4 loses radial constraint, and it can be conveniently and safely removed vertically from above the mixing bin 1. This ingenious snap-locking and quick-release mechanism significantly simplifies the daily fertilization operation process and greatly facilitates growers to timely and efficiently put various forms of fertilizer (powder, granules) into the device according to the precise fertilization needs of pomelo at different growth stages.

[0031] Working principle: After fertilizer is added to the feeding hopper 4, the fixing pipe 12 at the feeding hopper 4 is connected to the fixing ring 3. The fixing screw 13 is rotated to move within the fixing pipe 12, causing the fixing screw 13 to drive the splined shaft 15 to press against the locking block 17, causing the locking block 17 to pop out and press against the bottom of the feeding hopper 4, thus fixing the feeding hopper 4. When the fixing screw 13 rotates in the opposite direction, the spring force of the return spring 16 can retract the locking block 17, allowing the feeding hopper 4 to be disassembled for easy fertilizer addition. During installation, the transmission rod 6 is connected to the splined shaft 15 at the connecting shell 14, and then the drive motor 9 is started to drive the bevel gear. When bevel gear 10 rotates, it drives bevel gear 11, which in turn drives connecting frame 5 and transmission rod 6. The rotation of transmission rod 6 drives spline shaft 15 to rotate inner mixing frame 8, causing fertilizer and pre-added water in dispensing bin 4 to be mixed and the fertilizer to dissolve. After dissolving, the mixture permeates from the filter screen at dispensing bin 4 into the inner side of mixing bin 1, while impurities remain in dispensing bin 4. When connecting frame 5 rotates, it can stir the fertilizer inside mixing bin 1, facilitating fertilizer mixing and thus achieving water and fertilizer mixing and fertilizer filtration, improving mixing efficiency, and preventing impurities from clogging discharge pipe 2, ensuring normal irrigation.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
