Description

Technical Field

[0001] This utility model relates to the field of fertilization technology, and more specifically, to an agricultural fertilization device for uniform fertilization. Background Technology

[0002] In modern agricultural production, fertilization devices are key technological equipment for achieving scientific fertilization and precision nutrient management of crops. The stability of their performance and the ease of operation and maintenance directly affect agricultural production efficiency and the quality of fertilization operations. In actual use, fertilization devices require the feeding of various fertilizers, such as granular or powdered chemical fertilizers and organic fertilizers, into the internal space of the feed cylinder at the top of the device. The feed cylinder serves as a temporary storage container and primary conveying channel for the fertilizer, performing both temporary storage and downward conveying functions. Once a certain amount of fertilizer has accumulated in the feed cylinder, the fertilization device needs to use a feeding mechanism located in the lower internal space of the feed cylinder to release the fertilizer. The pusher arm performs a mechanical pushing operation. Driven by the drive mechanism, the pusher arm swings or rotates back and forth. Utilizing the friction and pushing force between the surface of the arm and the fertilizer particles, the fertilizer accumulated at the bottom of the feed cylinder is gradually pushed to the position of the discharge plate below. The discharge plate, as the core working component of the fertilization device, rotates at high speed under the drive of the power system. When the fertilizer pushed down by the pusher arm falls onto the surface of the high-speed rotating discharge plate, the fertilizer particles are quickly thrown off the plate and scattered in all directions along the radial direction of the discharge plate under the action of the centrifugal force generated by the rotation of the discharge plate, thereby realizing the spreading and application of fertilizer on the surface of farmland soil.

[0003] However, this traditional fertilizer application device, which relies on a pusher rod for fertilizer delivery, has revealed reliability and maintenance difficulties during long-term continuous use. The pusher rod needs to continuously and frequently come into contact with fertilizer particles of various hardness and size through friction and impact. Furthermore, fertilizers often contain corrosive chemicals that continuously erode the surface of the pusher rod. In addition, fertilizers may absorb moisture from the air during storage and transportation, leading to agglomeration and increasing the workload and stress on the pusher rod. The cumulative effect of these adverse factors over a period of time makes the pusher rod prone to various forms of damage and failure, such as severe surface wear, bending and deformation, loosening of connections, and even breakage. Once the pusher rod fails, it directly affects the fertilizer delivery. The continuous operation of normal fertilizer delivery and fertilization can lead to decreased fertilization efficiency, poor uniformity of fertilization, and even equipment shutdown. However, the feed levers of existing fertilizer application devices are usually installed in the narrow space inside the feed cylinder using traditional connection methods such as welding, bolting, or pin insertion. When the feed lever is damaged and needs to be replaced, maintenance personnel must first clean all the residual fertilizer in the feed cylinder, and then disassemble the feed cylinder or surrounding obstructions to barely reach the installation position of the feed lever. Then, various special tools such as wrenches, screwdrivers, and welding equipment are used to carry out tedious and complicated disassembly and installation operations. The entire feed lever replacement process consumes a lot of labor time and maintenance costs. Moreover, ordinary agricultural machinery operators cannot independently complete the quick on-site replacement of the feed lever, which reduces the continuity of agricultural production and operational efficiency. Utility Model Content

[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides an agricultural fertilization device for uniform fertilization, so as to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: An agricultural fertilization device for uniform fertilization includes a trolley with a protective shell on its upper surface. A motor is mounted on the side wall of the protective shell, and a drive wheel is connected to the output end of the motor. A driven shaft is rotatably connected inside the protective shell, and a driven wheel is sleeved on the driven shaft. The drive wheel meshes with the driven wheel. The device also includes a quick-release mechanism, which includes a fixed cylinder with a connecting cylinder on its upper surface. A slip ring is sleeved on the outer wall of the connecting cylinder, and multiple sets of feeding rods are provided on the outer wall of the slip ring. The lower end face of the slip ring abuts against the upper end face of the fixed cylinder.

[0006] Preferably, two sets of first inclined wheels are sleeved at both ends of the driven shaft, and two sets of second inclined wheels are rotatably connected to the top of the inner sidewall of the protective shell. The second inclined wheels mesh with the corresponding first inclined wheels, and the power is transmitted through the meshing of the first and second inclined wheels.

[0007] Preferably, a third inclined wheel is rotatably connected to the top center position of the inner sidewall of the protective shell. The third inclined wheel meshes with the driven wheel, and a connecting rod is connected to the upper end of the third inclined wheel. The third inclined wheel directly meshes with the driven wheel shared with the discharge disc to take force, ensuring that a fixed transmission ratio is maintained between the rotation speed of the feeding rod and the rotation speed of the discharge disc.

[0008] Preferably, the upper end of the protective shell is symmetrically provided with two sets of discharge shells, and the upper ends of the two sets of second inclined wheels are connected to discharge discs. The discharge discs are located inside the two sets of discharge shells. The fertilizer is thrown out by the centrifugal force generated by the high-speed rotation of the discharge discs, thereby achieving the purpose of fertilization.

[0009] Preferably, the upper end face of the discharge shell is connected to the feed cylinder, the side wall of the feed cylinder is provided with a mounting frame, the mounting frame is connected to the trolley, and the fertilizer is injected into the feed cylinder for temporary storage before fertilization.

[0010] Preferably, the side wall of the connecting cylinder has multiple sets of inclined grooves, and a slider is slidably connected in the inclined groove. The side wall of the slider is provided with a locking block, which is slidably connected to the inclined groove. The locking block is used in conjunction with the slip ring. The lower end face of each set of sliders is provided with a connecting spring, and the other end of the connecting spring is fixedly connected to the inner side wall of the fixed cylinder. The slider drives the locking block to slide along the inclined groove to fix or unlock the slip ring.

[0011] Preferably, a threaded rod is rotatably connected inside the connecting cylinder, and the threaded rod is rotatably connected to the fixed cylinder. The side wall of the slider is provided with multiple sets of abutment springs, and the other end of the abutment spring is connected to a threaded plate. The threaded plate is threadedly connected to the threaded rod. This spiral transmission drive mechanism design, in which the rotation of the threaded rod drives the axial movement of the threaded plate and pushes the slider to slide along the inclined groove through the abutment spring, provides a controllable and convenient external driving force source for the quick-release mechanism.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides an agricultural fertilization device for uniform fertilization, which has the following beneficial effects: This invention organically combines a threaded radial locking mechanism with a sloped groove guide slider system to create a replacement solution that enables quick disassembly and secure fixing of the feed lever. It solves the problems of easy damage to the feed lever after long-term use in traditional fertilizer applicators, cumbersome and complex replacement operations, insufficient fixation reliability, and low maintenance efficiency. The device employs a multi-stage transmission mechanism that uses a threaded rod rotation drive combined with a spring-driven push-pull slider to slide along the sloped groove, driving multiple sets of locking blocks in radial linkage. This transforms the operator's simple threaded rod rotation into the radial forward and backward movement of the locking blocks. Compared to traditional welding, pin insertion, or bolt tightening methods, this threaded drive method has advantages such as low operating force requirement, short stroke, and fast disassembly and assembly speed. Maintenance personnel only need to gently rotate the threaded rod to install or remove the feed lever, reducing the skill threshold and operational difficulty of replacing the feed lever. Even in emergency scenarios such as field repairs where professional tools and maintenance conditions are lacking, ordinary agricultural machinery operators can quickly complete the loading and unloading of the feed lever, improving the convenience of equipment maintenance and the continuity of agricultural production.

Engagement: A third inclined wheel 19 is rotatably connected to the center of the top of the inner side wall of the protective shell 12. The third inclined wheel 19 engages with the driven wheel 16. A connecting rod 110 is connected to the upper end of the third inclined wheel 19. Two sets of discharge shells 111 are symmetrically arranged on the upper end of the protective shell 12. The upper ends of the two sets of second inclined wheels 18 are connected to discharge discs 112. The discharge discs 112 are located inside the two sets of discharge shells 111. The upper end of the discharge shell 111 is connected to the feed cylinder 113. The side wall of the feed cylinder 113 is provided with a mounting bracket 114. The mounting bracket 114 is connected to the trolley 11. It also includes a quick-release mechanism, which includes a fixed cylinder 21. The upper end of the fixed cylinder 21 is provided with a connecting cylinder 22. A slip ring 23 is sleeved on the outer wall of the connecting cylinder 22. Multiple sets of material-pulling rods 24 are provided on the outer wall of the slip ring 23. The lower end of the slip ring 23 abuts against the upper end of the fixed cylinder 21. Multiple sets of inclined grooves 25 are opened on the side wall of the connecting cylinder 22. A slider 26 is slidably connected in the inclined groove 25. A locking block 27 is provided on the side wall of the slider 26. The locking block 27 is slidably connected to the inclined groove 25 and is used in conjunction with the slip ring 23. A connecting spring 28 is provided on the lower end of each set of sliders 26. The other end of the connecting spring 28 is fixedly connected to the inner side wall of the fixed cylinder 21. A threaded rod 29 is rotatably connected in the connecting cylinder 22. The threaded rod 29 is rotatably connected to the fixed cylinder 21. Multiple sets of abutment springs 210 are provided on the side wall of the slider 26. The other end of the abutment spring 210 is connected to a threaded plate 211. The threaded plate 211 is threadedly connected to the threaded rod 29.

[0019] In this invention, fertilizer is injected into the feed cylinder 113. Then, the operator pushes the trolley 11 to move the fertilizer applicator forward, simultaneously starting the motor 13. The output of the motor 13 drives the drive wheel 14 to rotate. The drive wheel 14, through its meshing driven wheel 16, drives the driven shaft 15 to rotate. The rotation of the driven shaft 15 drives the first inclined wheels 17 at both ends to rotate synchronously. The rotation of the first inclined wheels 17 drives the corresponding meshing second inclined wheels 18 to rotate synchronously, thereby driving the two sets of discharge discs 112 to rotate simultaneously. The rotation of the driven wheel 16 also drives the third inclined wheel 19 to rotate. The third inclined wheel 19 drives the upper feed rod 24 to rotate synchronously through the connecting rod 110. The feed rod 24 pushes the fertilizer in the feed cylinder 113 through the discharge port at the bottom of the feed cylinder onto the lower discharge plate 112. The centrifugal force generated by the high-speed rotation of the discharge plate 112 throws the fertilizer out, completing the fertilization. When it is necessary to disassemble and replace the feed rod 24, the operator can rotate the threaded rod 29, which drives the threaded connection with it. Multiple sets of threaded plates 211 move, and the threaded plates 211 drive the corresponding sliders 26 to slide along the inclined groove 25 towards the smaller diameter end of the inclined groove 25 via the abutment spring 210. The abutment spring 210 is compressed, and the slider 26 drives the locking block 27 to move synchronously. The locking block 27 gradually retracts into the inclined groove 25, thereby releasing the abutment and fixing state of the locking block 27 against the side wall of the slip ring 23. Then the slip ring 23 can be removed together with the feeding rod 24. After that, a new slip ring 23 and feeding rod 24 are inserted, causing the slip ring 23 to descend. The end face abuts against the upper end face of the fixed cylinder 21. The operator rotates the threaded rod 29 in the opposite direction, driving multiple sets of threaded plates 211 to move downward. Through the abutment spring 210, the slider 26 slides along the inclined groove 25 to the larger end of the inclined groove 25. The abutment spring 210 rebounds, and the slider 26 drives the locking block 27 to move synchronously. The locking block 27 gradually extends out of the inclined groove 25 and then makes tight contact with the upper end face of the slip ring 23, thereby fixing the slip ring 23 together with the material feeding rod 24, realizing the quick replacement of the material feeding rod 24.
