Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a liquid fertilizer applicator with automatic fertilizer mixing function. Background Technology

[0002] A liquid fertilizer applicator is an agricultural machine specifically designed for applying liquid fertilizers. It mainly uses a mixing device to fully mix fertilizers with water (or other solvents) to form a uniformly concentrated fertilizer solution, which is then applied evenly and precisely to crops. It is widely used in agricultural production scenarios such as farmland, orchards, and vegetable bases.

[0003] Chinese patent document CN116671328A discloses a fertilizer applicator for uniform fertilization, comprising: a main body of the fertilizer applicator, including a movable support base plate, a storage tank, and a fertilization mechanism. The storage tank and fertilization mechanism are mounted on the movable support base plate and are connected to the storage tank. A lifting mechanism is installed on the top of the storage tank, and a stirring mechanism is installed inside the storage tank. The stirring mechanism is connected to the lifting mechanism. The operator can add liquid fertilizer into the storage tank through the hopper on the storage tank, and then start the fertilization mechanism, lifting mechanism, and stirring mechanism through a control switch and power module. The lifting mechanism can drive the stirring mechanism to rotate up and down inside the storage tank, while the stirring mechanism can stir the liquid fertilizer inside the storage tank. The fertilization mechanism then sprays the liquid fertilizer evenly onto the corn, avoiding uneven mixing and sedimentation of the liquid fertilizer, and ensuring the uniformity of fertilizer composition.

[0004] However, in the above-mentioned solutions and existing technologies, since some fertilizers contain sticky components, such as organic fertilizers and compound fertilizers, they are prone to adhering to the inner wall of the storage tank during the stirring process. The stirring rod in the above invention cannot scrape off the fertilizer adhering to the inner wall of the storage tank during the stirring process. After long-term use, the residual fertilizer may harden and adhere to the inner wall of the storage tank, which not only affects the fertilization effect, but also increases the maintenance cost of the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a liquid fertilizer applicator with automatic fertilizer mixing function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a liquid fertilizer applicator with automatic fertilizer mixing function, comprising a rotating shaft, wherein an annular groove is formed on the outer surface of the rotating shaft, and further comprising a first mounting sleeve and a second mounting sleeve, the first mounting sleeve and the second mounting sleeve being fitted together to form an integral mounting sleeve, a first mounting seat being fixedly connected to the outer surface of both the first mounting sleeve and the second mounting sleeve, a first pin being fixedly connected to the outer wall of the first mounting seat, a connecting rod being rotatably connected to the outer wall of the first pin, a second pin being rotatably connected to the end of the connecting rod away from the first pin, a second mounting seat being fixedly connected to the outer wall of the second pin, and an elastic mounting component and a stirring and scraping component being fixedly connected to the side of the second mounting seat away from the connecting rod.

[0007] Preferably, both ends of the first pin are fixedly connected to a first limiting block, both ends of the second pin are fixedly connected to a second limiting block, and the outer surfaces of the first mounting sleeve and the second mounting sleeve are fixedly connected to two symmetrically arranged connecting plates.

[0008] Preferably, the outer surface of the connecting plate has two symmetrically arranged mounting holes, and a hexagonal bolt is inserted into the mounting hole. The outer wall of the hexagonal bolt is threaded with a fastening nut.

[0009] Preferably, the elastic mounting assembly includes a mounting plate fixedly connected to the side of the second mounting base away from the connecting rod, and a mounting groove is provided on the side of the mounting plate away from the second mounting base, with a movable plate slidably connected to the inner wall of the mounting groove.

[0010] Preferably, both inner walls of the mounting groove are provided with limiting grooves, the inner wall of the limiting groove is slidably connected to a limiting slider, and the side of the limiting slider away from the limiting groove is fixedly connected to the outer wall of the movable plate.

[0011] Preferably, the movable plate has multiple sliding holes on the side near the mounting groove. The sliding holes are arranged in a longitudinal linear array. The inner wall of each sliding hole is slidably connected to a mounting rod. The end of the mounting rod away from the sliding hole is fixedly connected to the bottom of the inner cavity of the mounting groove.

[0012] Preferably, a spring is sleeved on the outer wall of the mounting rod, one end of the spring abuts against the side of the movable plate near the mounting groove, and the other end of the spring abuts against the bottom of the inner cavity of the mounting groove.

[0013] Preferably, the agitating scraping assembly includes a fixed plate fixedly connected to the side of the movable plate away from the mounting groove, the fixed plate having a fixed groove on the side away from the movable plate, and an agitating scraping plate inserted into the inner wall of the fixed groove.

The outer surface of the agitating scraper plate has two through holes that facilitate the passage of the two threaded rods and are symmetrically arranged.

[0015] Preferably, a knob is fixedly connected to the end of the threaded rod away from the threaded groove, and three turning plates are fixedly connected to the outer surface of the knob, the three turning plates being arranged in a ring array.

[0016] Compared with the prior art, this application has the following beneficial effects: By combining the flexible mounting component with the agitating scraper component, centrifugal force is used to unfold and adhere the agitating scraper plate to the inner wall of the storage tank when the shaft rotates. This effectively scrapes away fertilizer adhering to the inner wall of the storage tank while simultaneously mixing fertilizer and water, preventing the fertilizer from hardening over time and ensuring fertilization efficiency. The spring design in the flexible mounting component allows the movable plate to slide elastically during scraping, achieving flexible scraping and preventing damage to the inner wall of the storage tank from excessive scraping force, thus extending the equipment's service life. The agitating scraper component features a detachable design; the agitating scraper plate is fixed to the fixed plate using a threaded rod and threaded groove connection. When the agitating scraper plate needs to be replaced, it can be easily disassembled and installed simply by rotating the threaded rod, making operation simple and convenient.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-8 This invention provides a technical solution: a liquid fertilizer applicator with automatic fertilizer mixing function, including a rotating shaft 1, which is the core driving component of the entire device. One end of the rotating shaft 1 is connected to the drive motor on the fertilizer applicator and rotates under the drive of the drive motor to provide power for the entire mixing and scraping process. The outer surface of the rotating shaft 1 is provided with an annular groove 4. It also includes a first mounting sleeve 2 and a second mounting sleeve 3, which are joined together to form an integral mounting sleeve. The outer surfaces of the first mounting sleeve 2 and the second mounting sleeve 3 are fixedly connected to a first mounting seat 7. The outer wall of the first mounting seat 7 is fixedly connected to a first pin 14. The outer wall of the first pin 14 is rotatably connected to a connecting rod 8. The end of the connecting rod 8 away from the first pin 14 is rotatably connected to a second pin 16. The outer wall of the second pin 16 is fixedly connected to a second mounting seat 15. The side of the second mounting seat 15 away from the connecting rod 8 is fixedly connected to an elastic mounting component 5 and a stirring and scraping component 6. This connection structure forms a movable linkage mechanism, which allows the elastic mounting component 5 and the stirring and scraping component 6 to move flexibly within a certain range. Both ends of the first pin 14 are fixedly connected to the first limiting block 9, and both ends of the second pin 16 are fixedly connected to the second limiting block 17. The function of the first limiting block 9 and the second limiting block 17 is to prevent the connecting rod 8 from falling off the first pin 14 and the second pin 16 during rotation, thus ensuring the stability and reliability of the entire linkage mechanism. The outer surfaces of the first mounting sleeve 2 and the second mounting sleeve 3 are fixedly connected to two symmetrically arranged connecting plates 10. Two symmetrically arranged mounting holes 12 are opened through the outer surface of the connecting plate 10. Hexagonal bolts 11 are inserted into the mounting holes 12, and fastening nuts 13 are threaded onto the outer wall of the hexagonal bolts 11. By passing the hexagonal bolts 11 through the mounting holes 12 and tightening the fastening nuts 13 onto the hexagonal bolts 11 with a wrench, the first mounting sleeve 2 and the second mounting sleeve 3 can be firmly connected together to form a stable integral structure. This design allows it to be firmly fixed on the rotating shaft 1 and rotate together with the rotating shaft 1.

[0021] In actual use, firstly, the first mounting sleeve 2 and the second mounting sleeve 3 are joined together in the annular groove 4 of the rotating shaft 1 to form a single mounting sleeve, ensuring a tight fit between the mounting sleeve and the rotating shaft 1. Then, the hexagonal bolt 11 is passed through the mounting hole 12 on the connecting plate 10, and the fastening nut 13 is tightened onto the hexagonal bolt 11 using a wrench, so that the first mounting sleeve 2 and the second mounting sleeve 3 are firmly connected, forming a stable integral structure. The installed device is then placed inside the fertilizer applicator's storage tank, ensuring that the device can rotate freely and maintain a proper contact with the inner wall of the storage tank. At the appropriate distance, connect one end of the rotating shaft to the drive motor on the fertilizer applicator, ensuring a firm connection and stable transmission. Start the drive motor, which drives the rotating shaft 1 to rotate. The rotating shaft 1 drives the entire device to rotate through the first mounting sleeve 2 and the second mounting sleeve 3. Under the centrifugal force generated during the rotation of the rotating shaft 1, the elastic mounting component 5 and the stirring and scraping component 6 unfold through the first mounting base 7, the first pin 14, the connecting rod 8, the second mounting base 15, and the second pin 16, so that the stirring and scraping plate 603 fits against the inner wall of the storage tank.

[0022] The flexible mounting assembly 5 includes a mounting plate 501 fixedly connected to the side of the second mounting base 15 away from the connecting rod 8. A mounting groove 502 is formed on the side of the mounting plate 501 away from the second mounting base 15. A movable plate 506 is slidably connected to the inner wall of the mounting groove 502. Limiting grooves 505 are formed on both inner side walls of the mounting groove 502. Limiting sliders 507 are slidably connected to the inner walls of the limiting grooves 505. The side of the limiting slider 507 away from the limiting grooves 505 is fixedly connected to the outer side wall of the movable plate 506. This design allows the movable plate 506 to slide only within the mounting groove 502 along the direction of the limiting grooves 505, thus restricting the direction of movement of the movable plate 506. A mounting groove 502 is formed on the side of the movable plate 506 closest to the mounting groove 502. There are multiple sliding holes 508, which are arranged in a longitudinal linear array. The inner wall of the sliding holes 508 is slidably connected to the mounting rod 503. The end of the mounting rod 503 away from the sliding holes 508 is fixedly connected to the bottom of the inner cavity of the mounting groove 502. During the process of scraping off the attached fertilizer, the movable plate 506 will slide in the mounting groove 502 under the action of force and compress the spring 504. The elastic force of the spring 504 can play a buffering role, realize flexible scraping, and avoid damage to the inner wall of the storage tank due to excessive scraping force. The outer wall of the mounting rod 503 is fitted with the spring 504. One end of the spring 504 abuts against the side of the movable plate 506 near the mounting groove 502, and the other end of the spring 504 abuts against the bottom of the inner cavity of the mounting groove 502.

[0023] In actual use, during the rotation of the device, on the one hand, the fertilizer and water in the storage tank are stirred to fully mix and form a uniform fertilizer solution. On the other hand, the stirring scraper 603 scrapes off the fertilizer adhering to the inner wall of the storage tank as it adheres to the inner wall. During the scraping process, the movable plate 506 slides along the limiting groove 505 in the mounting groove 502 of the mounting plate 501 under the action of force, while compressing the spring 504 to achieve flexible scraping and avoid damage to the inner wall of the storage tank.

[0024] The agitating scraping assembly 6 includes a fixed plate 601 fixedly connected to the side of the movable plate 506 away from the mounting groove 502. A fixing groove 605 is formed on the side of the fixed plate 601 away from the movable plate 506, and an agitating scraping plate 603 is inserted into the inner wall of the fixing groove 605. By holding and rotating the knob 602 on the rotating plate 604, the threaded rod 607 can be rotated, causing the threaded rod 607 to pass through the through hole 608 and be screwed into the threaded groove 606 until tightened, thereby firmly fixing the agitating scraping plate 603 to the fixed plate 601. Two threaded grooves 606 are formed through the outer surface of the fixed plate 601, and the two threaded grooves 606 are symmetrically arranged. Each threaded groove 606 has a threaded rod 607 threadedly connected to its inner wall. The outer surface of the agitating scraper 603 has two through holes 608 through which the two threaded rods 607 can pass. The two through holes 608 are symmetrically arranged. A knob 602 is fixedly connected to the end of the threaded rod 607 away from the threaded groove 606. Three rotating plates 604 are fixedly connected to the outer surface of the knob 602. The three rotating plates 604 are arranged in a ring array. When the agitating scraper 603 needs to be replaced, the threaded rod 607 is rotated in the opposite direction to disengage it from the through hole 608 and the threaded groove 606. The agitating scraper 603 can then be pulled out of the fixed groove 605 for replacement.

[0025] In actual use, when it is necessary to replace the agitator scraper, the operator first stops the equipment and then removes the device from the storage tank. Next, the operator holds the screwing plate 604 and turns the knob 602, thereby driving the threaded rod 607 to rotate, causing the threaded rod 607 to disengage from the through hole 608 and the threaded groove 606. Then, the old agitator scraper 603 is pulled out from the fixing groove 605 on the fixing plate 601, and the new agitator scraper 603 is inserted into the fixing groove 605 on the fixing plate 601. The threaded rod 607 is then rotated in the opposite direction to pass through the through hole 608 and screwed into the threaded groove 606 until it is tightened, thus completing the replacement of the agitator scraper 603.
