Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation and fertilization technology, specifically to an integrated water and fertilizer irrigation device for improving crop yield per unit area. Background Technology

[0002] By dissolving fertilizer in water for irrigation, nutrients can be distributed more evenly in the soil and closer to crop roots, greatly improving fertilizer utilization. In this regard, the integrated water and fertilizer irrigation technology, as highlighted in the Henan Provincial Key Research and Development and Promotion Project (Science and Technology Breakthrough) (Project No. 232102110051), has significant advantages. It dissolves fertilizer in water for irrigation, allowing nutrients to be evenly distributed in the soil in ionic form, closer to crop roots, reducing nutrient fixation and loss in the soil. Compared with traditional fertilization methods, fertilizer utilization can be increased by 20%-30%, effectively promoting crop growth and increasing yield. At the same time, this technology combines fertilization and irrigation, eliminating the need for separate fertilization operations, saving a lot of labor and time costs, improving agricultural production efficiency, and allowing farmers to devote more energy to other agricultural production management aspects, optimizing agricultural production, and indirectly contributing to increased yield per unit area. It can be called a highly efficient means to increase crop yield per unit area.

[0003] However, current water and fertilizer irrigation still faces problems in practical applications. Many integrated water and fertilizer irrigation devices on the market have various structures such as accelerated mixing and auxiliary spraying to achieve diverse effects. Although these structures can operate independently step by step, they lack unified and reasonable coordination, making the installation process complicated and causing great inconvenience to subsequent users. Even if there is an integrated structure, it is difficult to adjust flexibly according to the actual situation, which to some extent limits the full realization of the advantages of this technology and requires further optimization and improvement.

A pulverizing shaft is rotatably connected inside the filter cylinder. Wheels are fixedly mounted at the top of both the pulverizing shaft and the output shaft of the drive motor. There are four wheels in total. Two belts are driven onto the surfaces of the two wheels at corresponding heights. The wheel at the top of the drive motor output shaft is connected to the drive motor output shaft via a ratchet bearing. The ratchet bearing includes a mounting housing welded to the bottom of the wheel. A ratchet body is rotatably connected to the inner side of the mounting housing. The surface of the ratchet body has several ratchet teeth. A limiting spring is fixedly mounted on the inner wall of the mounting housing for limiting movement. A pawl is fixedly mounted at one end of each limiting spring for limiting movement. The pawl abuts against the ratchet teeth on the surface of the ratchet body. There are four pawls in total. Three limiting springs are provided between each pawl and the inner wall of the mounting housing. The output shaft of the drive motor is sleeved inside the ratchet body. The filter cylinder is threaded to the bottom of the upper protective cover. Pulverizing blades are mounted on the surface of the pulverizing shaft.

[0008] Preferably, the adjustment unit includes a connecting frame bolted to the surface of the storage cylinder for support. The connecting frame is threaded onto the surface of the storage cylinder. A supporting shaft is rotatably connected to the top of the connecting frame. Two wheels of a different height are fixedly installed at the middle of the supporting shaft and the middle of the drive motor. Another belt is driven onto the surfaces of the two wheels of the different height. A half gear is fixedly installed on the surface of the supporting shaft near the connecting frame. An auxiliary outer tube is rotatably connected inside the connecting frame. A full gear is fixedly installed at the top of the auxiliary outer tube. The full gear and the half gear mesh with each other. The full gear and the half gear have different radii. A connecting plate with a hole is welded to the bottom of the auxiliary outer tube. A torsion spring for resetting is fixedly installed between the top of the connecting plate and the bottom of the connecting frame. A torsion spring is installed between the auxiliary outer tube and the connecting frame. A through hole is provided on the surface of the auxiliary outer tube.

[0009] Preferably, the spraying unit includes a spraying inner tube that is non-contact sealed and rotatably connected to both the auxiliary outer tube and the connecting plate with the opening. The bottom end of the spraying inner tube is non-contact sealed and rotatably connected to a pipe responsible for conveying water and connected to the outlet of the storage cylinder. A water pump that drives the water flow is installed in the middle section of the pipe.

[0011] The beneficial effects of the above technical solution are as follows:

[0012] In this solution, the drive motor can simultaneously drive various units to cooperate with each other, realizing functions such as water and fertilizer storage, mixing, crushing and spraying, providing crops with an integrated irrigation solution, which helps to increase crop yield. The cooperation between the mixing shaft and mixing blades, as well as the crushing shaft and crushing blades, can achieve multi-stage melting and mixing of fertilizer and water, which greatly improves the mixing effect and reduces the traditional water and fertilizer mixing time and actual working cycle. By connecting the top of the drive motor output shaft and the wheel with a ratchet bearing, the opening and closing of the crushing unit can be controlled by changing the drive mode, thereby controlling the total amount of fertilizer fed, thereby changing and adjusting the water and fertilizer concentration, so that the crops can be in a more suitable water and fertilizer environment for growth, ensuring irrigation and fertilization efficiency.

[0013] In this design, the adjustment unit achieves the reciprocating rotation of the auxiliary outer pipe through the intermittent meshing of half-gears and full-gears and the action of torsion springs. This allows for the adjustment of parameters such as irrigation flow and angle to adapt to the needs of different crops and different growth stages, improving the accuracy and adaptability of irrigation. The spraying unit delivers water and fertilizer to the inner spraying pipe via a water pump and uses transmission gears to rotate the inner spraying pipe, achieving uniform spraying of water and fertilizer. The non-contact sealing treatment can reduce water and fertilizer leakage to a certain extent, improving irrigation efficiency and reducing water and fertilizer waste. At the same time, the rotating inner spraying pipe can expand the spraying range, making irrigation more comprehensive. Attached Figure Description

Detailed Implementation

[0024] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 9 As will be clearly shown in the detailed description of the embodiments, all structural contents mentioned in the following embodiments are based on the accompanying drawings.

[0025] Example 1: This example provides an integrated water and fertilizer irrigation device for increasing crop yield, such as... Figure 1-3 As shown, it includes a support base frame 1, a storage cylinder 2 welded to the inner side of the support base frame 1, an upper protective cover 3 snapped onto the top of the storage cylinder 2, a drive motor 11 mounted on the top of the upper protective cover 3 by bolts, a stirring unit set inside the upper protective cover 3, a crushing unit set between the drive motor 11 and the upper protective cover 3, an adjustment unit and a spraying unit set between the drive motor 11 and the storage cylinder 2, and the spraying unit part of the structure is threaded on the top of the support base frame 1;

[0026] In this embodiment, the support frame 1 provides fixed support for the overall structure and provides a stable working environment for the storage cylinder 2, which is welded to the inside and used to store liquid. The storage cylinder 2 can store liquid and limit the upper protective cover 3 for sealing protection. At the same time, it can also provide installation space for the stirring unit, crushing unit, adjustment unit and spraying unit in conjunction with the upper protective cover 3. The stirring unit is responsible for stirring and mixing water and fertilizer, reducing the traditional water and fertilizer mixing time. The crushing unit can crush and screen larger fertilizer particles to further improve water and fertilizer mixing. The adjustment unit is responsible for assisting and limiting the spraying, improving the flexibility of spraying control, and working with the spraying unit to achieve reasonable and efficient control of the actual spraying.

[0027] Example 2, based on Example 1, is improved in that, as follows: Figure 4 As shown, the stirring unit includes a stirring shaft 8 rotatably mounted inside the upper protective cover 3 and located inside the storage cylinder 2. The stirring shaft 8 is rotatably connected inside the upper protective cover 3. Stirring blades 22 are mounted on the surface of the stirring shaft 8. A drive gear 12 is fixedly mounted on the surface of the output shaft of the drive motor 11 near the drive motor 11. A driven gear 23 is fixedly mounted on the top of the stirring shaft 8. The drive gear 12 and the driven gear 23 mesh with each other. The stirring blades 22 are located inside the storage cylinder 2.

[0028] In this embodiment, one end of the stirring shaft 8 is rotatably connected to the inside of the upper protective cover 3. This rotatable connection ensures that the stirring shaft 8 can rotate smoothly. At the same time, the stirring blades 22 can also increase the speed of liquid flow and ensure the actual water-fertilizer mixing efficiency. The drive motor 11 drives the stirring shaft 8 to rotate through the drive gear 12 and the driven gear 23. With the help of the stirring blades 22 on the stirring shaft 8, the added fertilizer and water are accelerated to contact, mix and dissolve, which greatly reduces the occurrence of fertilizer accumulation and uneven water-fertilizer mixture.

[0029] Example 3, based on Example 2, is improved in that, as follows: Figure 5 , Figure 8 and Figure 9As shown, the pulverizing unit includes a filter cylinder 24 bolted to the bottom of the upper protective cover 3 and located inside the storage cylinder 2. A pulverizing shaft 5 is rotatably connected inside the filter cylinder 24. Rotary wheels 6 are fixedly mounted at the top of both the pulverizing shaft 5 and the output shaft of the drive motor 11. There are four rotary wheels 6 in total. Two belts 7 are driven onto the surfaces of two rotary wheels 6 at corresponding heights. The rotary wheels 6 at the top of the output shaft of the drive motor 11 are connected to the output shaft of the drive motor 11 via ratchet bearings. The ratchet bearings include a mounting housing 26 welded to the bottom of the rotary wheels 6. The inner side of the mounting housing 26... A ratchet body 29 is rotatably connected. The surface of the ratchet body 29 has several ratchet teeth. A limiting spring 27 for limiting is fixedly installed on the inner wall of the mounting housing 26. A pawl 28 for limiting is fixedly installed at one end of the limiting spring 27. The pawl 28 abuts against the ratchet teeth on the surface of the ratchet body 29. There are four pawls 28. There are three limiting springs 27 between each pawl 28 and the inner wall of the mounting housing 26. The output shaft of the drive motor 11 is sleeved inside the ratchet body 29. The filter cartridge 24 is threaded to the bottom of the upper protective cover 3. The crushing shaft 5 is equipped with crushing blades 21.

[0030] In this embodiment, by setting up the rotating wheel 6 and cooperating with the belt 7, the purpose of transmission with the drive motor 11 can be achieved. At the same time, the rotating wheel 6 at the top of the output shaft of the drive motor 11 is connected to the output shaft of the drive motor 11 through a ratchet bearing, which can ensure that the belt 7 can only control the crushing and feeding work in one direction. (When the ratchet bearing is actually working, if the output shaft of the drive motor 11 drives the ratchet body 29 to rotate clockwise, the ratchet teeth and pawl 28 of the ratchet body 29 are locked together, and the ratchet body 29 and the mounting shell 26 rotate. When the output shaft of the drive motor 11 rotates counterclockwise, the ratchet teeth and pawl 28 of the ratchet body 29 are at the same angle, and with the help of the limiting spring 27, the pawl 28 repeatedly disengages from the ratchet teeth on the surface of the ratchet body 29. At this time, no force is generated to push the mounting shell 26, so there is no force to push the ratchet body 29.) The filter cartridge 24, with its rotating housing 26, directly filters and restricts fertilizer to ensure feeding requirements. The crushing shaft 5 is rotatably connected inside the filter cartridge 24. This connection method improves the smoothness of the filter cartridge 24's rotation and its operational stability. The crushing blades 21 further increase the efficiency of the crushing process. The drive motor 11 drives the filter cartridge 24 in one of its designed directions. With the aid of a ratchet bearing, when there is no relative movement between the output shaft of the drive motor 11 and the corresponding rotating wheel 6, it drives the crushing shaft 5 and the crushing blades 21 connected to it to rotate, thus crushing the fertilizer and assisting in feeding. When the drive motor 11 rotates in the opposite direction, due to friction and other external forces, it cannot drive the crushing shaft 5 and the crushing blades 21 to rotate, stopping the crushing and feeding of fertilizer, thus precisely ensuring control of the water-fertilizer mixture concentration.

[0031] Example 4, based on Example 3, is improved in that, as follows: Figure 6 As shown, the adjustment unit includes a connecting frame 13 that is bolted to the surface of the storage cylinder 2 and used for support. The connecting frame 13 is threaded to the surface of the storage cylinder 2. A support shaft 14 is rotatably connected to the top of the connecting frame 13. Two wheels 6 of the same height are fixedly installed at the middle position of the support shaft 14 and the middle position of the drive motor 11. Another belt 7 is driven on the surface of the two wheels 6 of the same height. A half gear 10 is fixedly installed on the surface of the support shaft (14) near the connecting frame 13. An auxiliary outer tube 16 is rotatably connected inside the connecting frame 13. A full gear 15 is fixedly installed at the top of the auxiliary outer tube 16. The full gear 15 and the half gear 10 mesh with each other. The full gear 15 and the half gear 10 have different radii. A connecting plate 25 with a hole is welded to the bottom of the auxiliary outer tube 16. A torsion spring 18 for resetting is fixed between the top of the connecting plate 25 and the bottom of the connecting frame 13. A through hole is provided on the surface of the auxiliary outer tube 16.

[0032] In this embodiment, the connecting frame 13 provides a safe and stable installation environment for the supporting shaft 14 and the auxiliary outer tube 16, greatly ensuring the overall stability of the structure. The half gear 10 is located on the corresponding driving side and can drive the driven full gear 15 to rotate intermittently. The torsion spring 18 can assist in resetting the full gear 15 when it is unrestricted. When the drive motor 11 is working, it drives the supporting shaft 14 and the half gear 10 to rotate. The half gear 10 drives the full gear 15 and the auxiliary outer tube 16 to rotate. When the contact between the half gear 10 and the full gear 15 is interrupted, the auxiliary outer tube 16 can be reset in a short time by means of the characteristics of the torsion spring 18, and the auxiliary outer tube 16 can be driven to swing back and forth, improving the flexibility of actual irrigation control.

[0033] Example 5, based on Example 4, is improved in that, as follows: Figure 7 As shown, the spraying unit includes a spraying inner tube 17 that is non-contact sealed and rotatably connected to the auxiliary outer tube 16 and the opening connecting plate 25. The bottom end of the spraying inner tube 17 is non-contact sealed and rotatably connected to a pipe 19 that is responsible for conveying water and connected to the discharge port of the storage tank 2. A water pump 20 that drives the water flow is installed in the middle section of the pipe 19. The spraying inner tube 17 and the top of the support shaft 14 are both fixedly equipped with mutually meshing transmission gears 9. The spraying inner tube 17 is also non-contact sealed and rotatably connected to the gear 15 and the auxiliary outer tube 16. The spraying inner tube 17 has a structure that is hollow inside and at the bottom and solid at the top, and has several spraying holes on the surface. The top of the upper protective cover 3 is equipped with a hanging ring 4. A turbidity sensor is installed at the discharge position at the bottom of the storage tank 2. A water inlet is installed on one side of the storage tank 2.

[0034] In this embodiment, when the water pump 20 is working, it draws the mixed liquid from the pipe 19 into the inner spray pipe 17 and sprays it to the outside. In actual operation, the water pump 20 can reasonably adjust the spray pressure according to the spraying requirements. Reasonable spraying will greatly improve the planting and growth environment of crops. When the supporting shaft 14 is driven to rotate, it can drive the inner spray pipe 17 to rotate continuously with the transmission gear 9. The spray nozzle can spray and irrigate crops in a wide range of environments. The drive motor 11 works to drive the supporting shaft 14 to rotate. With the help of two transmission gears 9, the corresponding inner spray pipe 17 rotates. The inner spray pipe 17 and the auxiliary outer pipe 16 with cross section move with each other to irrigate products in different ranges efficiently and flexibly. By setting the hanging ring 4, the upper protective cover 3 can be disassembled. By setting the water inlet, the mixed water can be added. By setting the turbidity sensor, the turbidity of the mixed liquid inside the storage tank 2 can be monitored to monitor the water and fertilizer concentration, helping the staff to achieve excellent irrigation conditions.

[0035] Working principle: In use, firstly, with the help of the support frame 1, the structure is installed at the irrigation position, and a large amount of fertilizer is added into the filter cylinder 24. The water inlet is then connected to the external water supply equipment. After connection, an appropriate amount of water is injected, and the drive motor 11 is controlled to drive in one direction. At this time, the drive motor 11 can drive the drive gear 12 to rotate, and the drive gear 12 transmits the driven gear 23, which drives the stirring shaft 8 and the stirring blades 22 to rotate, thus agitating the liquid inside the storage cylinder 2. When the drive motor 11 is working, it also uses the rotating wheel 6 and belt 7. Since the top of the output shaft of the drive motor 11 is connected to the rotating wheel 6 through a ratchet bearing, when the ratchet bearing and the output shaft of the drive motor 11 do not move relative to each other, the crushing shaft 5 is driven. The rotating crushing blades 21, through their cutting friction, pulverize the fertilizer. Simultaneously, the rotating blades 21 push fine fertilizer particles out of the filter holes of the filter cartridge 24, aiding in fertilizer feeding. Furthermore, the small powdery fertilizer particles dissolve more quickly in water, increasing dissolution efficiency. When the drive motor 11 operates, it, along with the other rotating wheels 6 and belt 7, drives the support shaft 14 of the adjustment unit and the half-gear 10 to rotate. During the rotation of the half-gear 10, it drives the full gear 15, which meshes with it, to rotate. The full gear 15 drives the auxiliary outer tube 16, connected to the connecting frame 13, to rotate. When the half-gear 10 rotates to a certain angle, the half-gear 10 disengages from the full gear 15. The meshing full gear 15 and auxiliary outer tube 16 will be reset in a short time by the torque of the torsion spring 18, thereby continuously driving the auxiliary outer tube 16 to swing repeatedly. During the repeated swinging of the auxiliary outer tube 16, the rotation of the support shaft 14, in conjunction with the meshing transmission gear 9, can drive the spray inner tube 17, which is rotatably connected inside the auxiliary outer tube 16, to rotate continuously. (When the adjustment unit and the spraying unit are working together, when the drive motor 11 is working, in conjunction with the rotating wheel 6 and the belt 7, it drives the half gear 10 mounted on the support shaft 14 and the transmission shaft 9 to rotate in the same direction and at the same speed. Since the diameter and number of teeth of the half gear 10 and the full gear 15 are different, at this time, the half gear 10 and one of the transmission gears are driven respectively.) The meshing full gear 15 and another transmission gear 9 rotate in opposite directions. At this time, the full gear 15 and the other transmission gear 9 rotate in the same direction but at different speeds. This drives the auxiliary outer pipe 16 and the spraying inner pipe 17, which are connected to the full gear 15 and the other transmission gear 9 respectively, to work in the same direction but at different speeds. When the spray nozzle on the surface of the spraying inner pipe 17 rotates to the position of the through hole opened in the auxiliary outer pipe 16, external spraying and irrigation can be carried out (in other states, no external spraying occurs). Simultaneously, the water pump 20 is controlled to work, drawing the mixed water and fertilizer from the pipe 19 into the spraying inner pipe 17, and then spraying it out through the spray nozzle. Due to the above mechanical drive, the spraying inner pipe 17 rotates to spray, and the auxiliary outer pipe 16 repeatedly swings to assist spraying.At this time, large-scale and efficient irrigation is carried out on crops. During the irrigation control process, a turbidity sensor can be used to assist in detecting and controlling the concentration of irrigation water and fertilizer. When the concentration exceeds the appropriate level, the drive motor 11 can be reversed. In the reverse state, since all units except the crushing unit work in reverse, such as the stirring unit reversing its stirring, the adjusting unit reversing its rotation, and the spraying unit reversing its spraying (reversing the work does not affect the work process), the crushing unit, due to the characteristics of the ratchet bearing, will not experience significant friction with the wheel 6 connected to the top of the drive motor 11's output shaft when the drive motor 11 rotates in reverse. When the external friction is much greater than the internal friction, the relative movement between the drive motor 11's output shaft and the top wheel 6 causes the crushing shaft 5 and the crushing blades 21 to stop working. This is equivalent to stopping the crushing and feeding of fertilizer. In this way, the water and fertilizer concentration can be maintained within a reasonable range, allowing crops to grow in an optimal soil environment.

[0036] The above is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
