Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a mixing and fertilizing cart for farmland. Background Technology

[0002] The essence of soil fertilization is to replenish soil nutrients, provide energy for crops, and build ecological balance. It is not only the foundation for ensuring food security and improving the quality of agricultural products, but also the key to maintaining soil health, reducing environmental pressure, and achieving long-term sustainable agricultural development. In the future, with the promotion of technologies such as soil testing and formula fertilization, fertigation, and intelligent fertilization, fertilization will move from experience-based to precision-based, further amplifying its dual ecological and economic value.

[0003] Fertilizers are mainly classified into three categories: solid, liquid, and gaseous. Different forms of fertilizers differ significantly in physical properties, application methods, and applicable scenarios. Solid fertilizers are the most common type in agricultural production, and are mostly in granular, powdery, or block form, such as chemical fertilizers like urea and compound fertilizers. Liquid fertilizers exist in the form of aqueous solutions or suspensions, and common examples include humic acid liquid fertilizers, amino acid foliar fertilizers, and fertigation nutrient solutions. These fertilizers dissolve quickly and are rapidly absorbed by crops. Gaseous fertilizers have a relatively narrow range of applications, with carbon dioxide gas fertilizer being the core. They are mainly used in closed planting environments such as greenhouses, and are released through gas fertilizer generators or cylinders to supplement the carbon source needed for crop photosynthesis, helping to improve yield and quality.

[0004] Current fertilization methods still rely heavily on manual labor, with workers carrying fertilizer on their shoulders and using hand-held dispensing devices to apply it to the soil. This process not only consumes a lot of manpower but is also very slow. Some existing fertilizer sprayers have limited spraying range and cannot adapt to changes in the size of the land being sprayed. The sprayed material is also prone to clumping and uneven dissolution in the container, resulting in inconsistent fertilizer concentrations.

[0005] Therefore, there is an urgent need to develop a fertilizer mixing and application vehicle for farmland, which can effectively solve the problems of low fertilizer spraying efficiency and uneven fertilizer mixing in existing technologies. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a mixing and fertilizing cart for farmland, which can effectively solve the problems of low fertilizer spraying efficiency and uneven fertilizer mixing in the prior art.

[0007] The present invention relates to a mixing and fertilizing trolley for farmland, comprising a frame, a mixing assembly, and a spraying assembly. A bracket for fixing the mixing assembly is provided on one side of the top of the frame, and the spraying assembly is located on the side of the frame away from the bracket for spraying the mixed fertilizer.

[0008] The mixing assembly includes a material tank with a lid on top. A housing is located at the center of the lid, and a motor is located inside the housing. The output shaft of the motor passes through the lid and extends downward. A first gear is fixedly mounted on the end of the output shaft. A fixed rod is located below the first gear. One end of the fixed rod is fixedly connected to the first gear, causing the fixed rod to rotate synchronously with the first gear. The other end of the fixed rod is rotatably connected to a stirring rod via a bearing. The axis of the stirring rod forms an angle with the axis of the output shaft. A second gear is fixedly mounted on the top of the stirring rod, and the second gear meshes with the first gear. When the first gear rotates, the stirring rod revolves around the output shaft and simultaneously rotates on its own axis through the meshing of the first and second gears.

[0009] Furthermore, a spherical protrusion is provided at the intersection of the axis of the stirring rod and the axis of the motor output shaft, and the bottom of the stirring rod is also provided with several stirring paddles for expanding the stirring area.

[0010] Furthermore, a support rod is provided in the middle of the inner wall of the material barrel, and a ball joint bearing adapted to the spherical protrusion is provided at the end of the support rod. The spherical protrusion is hinged in the ball joint bearing to support the stirring rod and allow it to tilt and rotate.

[0011] Furthermore, the mixing assembly also includes a pressurizing mechanism located at the discharge port at the bottom of the hopper, used to pressurize the mixed fertilizer and then transport it through a pipeline to the spraying assembly.

[0012] Furthermore, the spraying assembly includes a main pipe and two auxiliary pipes. The main pipe is fixedly mounted on the vehicle frame via a base rod. The two auxiliary pipes are respectively connected to both ends of the main pipe via a hinge structure. The auxiliary pipes can be extended outward via the hinge structure and remain horizontal after being extended.

[0013] Furthermore, the main pipe and the auxiliary pipe are provided with multiple nozzles on one side along the direction of travel of the trolley, and the main pipe and the auxiliary pipe are connected to the discharge port of the material barrel through pipes.

[0014] Furthermore, the bucket lid is also equipped with a water inlet and a fertilizer inlet.

[0015] Furthermore, the rear of the vehicle frame is also equipped with a handle frame to facilitate personnel pushing the vehicle.

[0016] The beneficial effects of this utility model are as follows: The mixing and fertilizing trolley for farmland of this utility model makes the mixing rollers rotate around the first gear while rotating on their own axis, resulting in strong mixing force and ensuring a smooth and dead-angle-free mixing process. This makes the water-fertilizer mixture have a uniform concentration, which can effectively avoid the problems of fertilizer clumping and insufficient dissolution in traditional fertilization, leading to local over-fertilization or under-fertilization. The mixed fertilizer is then sprayed out through the deployable spraying component, which effectively widens the spraying range of the equipment and improves the efficiency of farmland fertilization.

[0024] This embodiment of the fertilizer mixing trolley for farmland includes a frame 6, a mixing assembly, and a spraying assembly. A bracket 4 for fixing the mixing assembly is provided on one side of the top of the frame 6. The spraying assembly is located on the side of the frame 6 away from the bracket 4 and is used to spray the mixed fertilizer. As shown in the figure, it includes a frame 6 as a supporting foundation, a mixing assembly for mixing fertilizer, and a spraying assembly for uniform spraying. A high-strength bracket 4 is welded or bolted to one side of the top of the frame 6. This bracket 4 is used to securely install the mixing assembly to withstand vibrations during operation. The spraying assembly is located on the other side of the frame 6 away from the bracket 4. This layout ensures a reasonable center of gravity distribution for the trolley, facilitating movement and turning, while allowing the mixed liquid fertilizer to be directly transported to the spraying assembly through pipes 8 for efficient and uniform spraying.

[0025] In this embodiment, the stirring assembly includes a material tank 1, a lid 2 on top of the material tank 1, a housing 3 at the center of the top of the lid 2, a motor 11 inside the housing 3, an output shaft of the motor 11 passing through the lid 2 and extending downwards, a first gear 13 fixedly mounted at the end of the output shaft, a fixing rod 15 below the first gear 13, one end of the fixing rod 15 fixedly connected to the first gear 13, causing the fixing rod 15 to rotate synchronously with the first gear 13, and the other end of the fixing rod 15 rotatably connected to a stirring rod 16 via a bearing, the axis of the stirring rod 16 being oriented perpendicular to the axis of the output shaft. The stirring roller 16 is inclined at an angle, and a second gear 14 is fixedly installed on its top. The second gear 14 meshes with the first gear 13, so that when the first gear 13 rotates, the stirring roller 16 revolves around the output shaft, and simultaneously rotates around its own axis through the meshing of the first gear 13 and the second gear 14. As shown in the figure, the top of the material tank 1 is provided with an openable lid 2, which facilitates the addition of solid fertilizer and internal cleaning. A sealed machine box 3 is fixed at the center of the top of the lid 2, and a motor 11, which serves as a power source, is installed inside. The output shaft of the motor 11 passes vertically downward through the lid 2 and extends to the material tank 1. Inside, at the end of the output shaft, a first gear 13 is fixedly mounted via a key connection or set screw. Below the first gear 13, a fixing rod 15 is provided. One end (upper end) of the fixing rod 15 is fixedly connected to the non-meshing surface of the first gear 13, thus enabling it to rotate synchronously with the first gear 13. The other end (lower end) of the fixing rod 15 is rotatably connected to a stirring roller 16 via a bearing (such as a deep groove ball bearing). The axis of the stirring roller 16 is designed to form an acute angle with the axis of the output shaft of the motor 11. To achieve complex planetary stirring motion, a second gear is fixedly mounted on the top of the stirring roller 16. The second gear 14 is always meshed with the first gear 13. Its working principle is as follows: after the motor 11 is started, it drives the first gear 13 to rotate. The first gear 13 drives the stirring roller 16 to "revolve" around the output shaft of the motor 11 through the fixed rod 15, which stirs the fertilizer in the edge area of ​​the material bucket 1. On the other hand, the meshing of the first gear 13 and the second gear 14 forces the second gear 14 to rotate, thereby driving the stirring roller 16 to "rotate" around its own axis, generating a strong local shear flow. The combined motion of revolution and rotation greatly improves the stirring efficiency and mixing uniformity, and can effectively prevent fertilizer sedimentation.

[0026] In this embodiment, a spherical protrusion is provided at the intersection of the axis of the stirring roller 16 and the axis of the output shaft of the motor 11. The bottom of the stirring roller 16 is also provided with several stirring paddles 21 for expanding the stirring area. As shown in the figure, a spherical protrusion is provided at the theoretical intersection of the axis of the stirring roller 16 and the axis of the output shaft of the motor 11. The spherical protrusion can be integrally formed with the stirring roller 16 or fixed by welding. At the same time, the bottom of the stirring roller 16 is also provided with several stirring paddles 21. The stirring paddles 21 not only further increase the stirring area, but their specific shape can also generate axial flow when rotating, promoting the up and down circulation of fertilizer in the material tank 1, thereby realizing all-round three-dimensional stirring and avoiding the generation of mixing dead corners.

[0027] In this embodiment, a support rod 17 is provided in the middle of the inner wall of the material barrel 1. The end of the support rod 17 is provided with a ball joint bearing adapted to the spherical protrusion. The spherical protrusion is hinged in the ball joint bearing to support the stirring rod 16 and allow it to tilt and rotate. As shown in the figure, one or more support rods 17 are radially provided in the middle of the inner wall of the material barrel 1. The end of the support rod 17 is equipped with a ball joint bearing adapted to the spherical protrusion. During assembly, the spherical protrusion on the stirring rod 16 is embedded and hinged in the ball joint bearing. The ingenious feature of this structural design is that it provides a reliable intermediate fulcrum for the stirring rod 16, which significantly improves the rigidity and stability of the entire transmission system. Furthermore, due to the characteristics of the ball joint, it does not interfere with the simultaneous revolution and rotation of the stirring rod 16, ensuring smooth stirring action.

[0028] In this embodiment, the mixing assembly further includes a pressurizing mechanism located at the discharge port at the bottom of the material tank 1, which is used to pressurize the mixed fertilizer and then transport it to the spraying assembly through the pipe 8. As shown in the figure, the mixing assembly also includes a pressurizing mechanism located at the discharge port at the bottom of the material tank 1. The pressurizing mechanism can be a small centrifugal pump or a diaphragm pump, the inlet of which is connected to the discharge port through the pipe 8. It is used to pressurize the mixed liquid fertilizer to obtain sufficient power so that it can be transported through the pipe 8 to the spraying assembly located at the front of the frame 6, providing the required pressure and flow rate for subsequent spraying.

[0029] In this embodiment, the spraying assembly includes a main pipe 9 and two auxiliary pipes 10. The main pipe 9 is fixedly mounted on the frame 6 via base rods 18. The two auxiliary pipes 10 are respectively connected to both ends of the main pipe 9 via hinge structures 20. The auxiliary pipes 10 can be extended outward via the hinge structures 20 and remain horizontal after being extended. As shown in the figure, it includes a horizontally arranged main pipe 9 and two symmetrically arranged auxiliary pipes 10. The main pipe 9 is firmly mounted on the front of the frame 6 via several base rods 18. The two auxiliary pipes 10 are respectively connected to both ends of the main pipe 9 via a dedicated hinge structure 20 (e.g., a hinge or pivot seat with locking function). The auxiliary pipes 10 can be extended outward around the hinge structure 20 by manual or simple mechanical assistance, thereby greatly increasing the spraying width and improving work efficiency. After being extended, the auxiliary pipes 10 can be locked in a state that is basically at the same horizontal line as the main pipe 9 by the limiting mechanism in the hinge structure 20 or an additional support rod 17, ensuring the uniformity of spraying across the entire spraying surface.

[0030] In this embodiment, the main pipe 9 and the secondary pipe 10 are provided with multiple nozzles 19 on one side along the direction of travel of the trolley. The main pipe 9 and the secondary pipe 10 are connected to the outlet of the material tank 1 through the pipe 8. As shown in the figure, multiple nozzles 19 are provided at uniform intervals on the bottom or side wall of the main pipe 9 and the secondary pipe 10 along one side along the direction of travel of the trolley. The nozzles 19 can be fan-shaped atomizing nozzles or direct current nozzles, which are selected according to the fertilization needs. The main pipe 9 and the secondary pipe 10 are connected to the outlet of the pressurizing mechanism at the bottom of the material tank 1 through the pipe 8, forming a complete liquid fertilizer delivery channel.

[0031] In this embodiment, the bucket lid 2 is also provided with a water inlet 7 and a feed inlet 12 for adding fertilizer; as shown in the figure, the bucket lid 2 is also provided with two independent openings: one is the water inlet 7, which is usually connected with a quick-connect water pipe connector for connecting to a water source; the other is the feed inlet 12 for adding solid or high-concentration liquid fertilizer, which can be equipped with a funnel with a sealing cap to prevent foreign matter from entering.

[0032] In this embodiment, the rear of the frame 6 is also provided with a handle 5 to facilitate personnel to push the trolley. As shown in the figure, the rear of the frame 6 is welded or bolted with an ergonomic handle 5. The handle 5 is at a moderate height, which makes it convenient for operators to push and control the direction of the trolley, thereby completing the fertilization operation of the entire farmland.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
