Description

Technical Field

[0001] This utility model relates to the field of fertilization technology, specifically to a fertilizer spreading device. Background Technology

[0002] Chemical fertilizers, as artificially synthesized fertilizers, contain a variety of rich nutrients, providing crops with comprehensive and sufficient nutrition. Unlike traditional farmyard manure, chemical fertilizers do not emit a strong odor and are simple and convenient to use, making them an indispensable fertilizer in modern agriculture. Crop cultivation cannot be separated from the supply of fertilizers, and to ensure that crops receive sufficient nutrients, many farmers choose to apply chemical fertilizers. In sugarcane and chili pepper planting areas, there are typically raised beds with crops planted on both sides. Farmers walk along the raised beds and apply fertilizer to the crops on both sides. This traditional method of applying fertilizer requires the fertilizer applicator to turn back and forth between the two sides of the bed, or to apply fertilizer to the crops on both sides separately, wasting manpower and time. The bending over also increases the physical fatigue of the fertilizer applicator. Because it is a manual operation, the fertilizer is often applied unevenly, resulting in some areas having too much fertilizer and others too little, which can lead to uneven crop development or even burn the seedlings.

[0003] To address the aforementioned technical issues, patent document CN223125324U discloses a dual-sided fertilizer spraying vehicle. Through fertilizer spreading devices facing both sides, it can spray fertilizer to both lateral directions, ensuring that crops on both sides of the field are fertilized after a single application. This eliminates the need for repeated back-and-forth fertilization and manual bending over to apply fertilizer, resulting in even fertilizer distribution and adjustable spraying distance. However, this device requires two discharge cylinders, two discharge motors, and a hub motor, leading to high costs for the fertilizer spraying vehicle. Utility Model Content

[0004] The main purpose of this utility model is to provide a fertilizer spreading device that can improve fertilization efficiency and has low equipment investment costs.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A fertilizer spreading device includes a mounting frame with fixed brackets on both sides of its lower end. The lower ends of the two fixed brackets are connected by a second traveling unit. A handrail is fixed to the rear end of the mounting frame, and two fixed rods are fixed to the lower end of the handrail. The lower ends of the two fixed rods are connected by a first traveling unit. A box is fixed to the mounting frame, and discharge pipes are fixedly connected to the left and right sides of the lower end of the box. The discharge ends of the discharge pipes are fixedly connected to a cylinder. The axial direction of the cylinder is parallel to the traveling direction of the device. An outlet is opened on the side of the cylinder opposite to the discharge pipe. A third rotating shaft is concentrically rotatable inside the cylinder. Multiple levers are evenly distributed and fixed to the outer circumference of the third rotating shaft. The end of the lever away from the third rotating shaft slides in contact with the inner edge of the cylinder. A transmission rod is rotatably connected between the two fixed brackets. The transmission rod is connected to the second traveling unit through a first transmission assembly, and the transmission rod is connected to the third rotating shaft through a second transmission assembly.

[0007] Specifically, the second walking unit includes a second rotating shaft, a motor is fixed on one of the fixed frames, the output shaft of the motor is concentrically fixedly connected to the second rotating shaft, the second rotating shaft is rotatably connected to the other fixed frame, and a second roller is concentrically fixed on the second rotating shaft.

[0008] Specifically, there are two second rollers.

[0009] Specifically, the first walking unit includes a first rotating shaft, on which a first roller is concentrically fixed.

[0010] Specifically, there are two first rollers.

[0011] Specifically, the first transmission assembly includes a belt, a driving wheel is concentrically fixed on the second rotating shaft, a driven wheel is concentrically fixed on the transmission rod, the driving wheel and the driven wheel are located on the same side, a clearance groove is provided in the fixing frame on one side of the driving wheel and the driven wheel, the belt, the driving wheel and the driven wheel are located in the clearance groove, and the driving wheel and the driven wheel are connected by belt drive.

[0012] Specifically, the transmission rod is a fourth rotating shaft, which is rotatably connected to two fixed frames. The second transmission assembly includes two second bevel gears concentrically fixed on the fourth rotating shaft, and a first bevel gear is concentrically fixed on the third rotating shaft. The two first bevel gears mesh with the two second bevel gears respectively.

[0013] Specifically, the transmission rod is a worm gear, which is rotatably connected to two fixed frames. The second transmission assembly includes a worm wheel concentrically fixed on a third rotating shaft, and the worm gear meshes with the worm wheel.

[0014] Specifically, a battery and a controller are fixed at the lower end of the mounting frame, and a speed control switch is fixed on the handrail. The battery, controller, and speed control switch are electrically connected.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The motor drives the second walking unit to move forward, and at the same time, the transmission system automatically triggers the spreading process, realizing integrated operation of moving and spreading. This reduces the labor intensity of manual spreading and is especially suitable for large-area farmland, enabling efficient completion of fertilization tasks.

[0017] 2. The paddle inside the cylinder rotates circumferentially with the third shaft, causing the fertilizer to be evenly distributed from the outlet. Combined with the design that the cylinder's axis is parallel to the direction of travel, the fertilizer can accurately cover the soil on both sides of the field ridges. This avoids localized over- or under-fertilization and improves the uniformity of crop growth.

[0018] 3. The dual-roller design of the first and second traveling units provides multi-point support, effectively preventing bumps or tipping during field movement. The rigid connection between the fixing frame and the mounting frame further strengthens the structure, enabling the device to operate stably even in rugged field ridges.

[0019] 4. The integrated battery, controller, and speed switch are located near the handrail, allowing users to adjust the travel speed and spreading rhythm in real time. This design lowers the barrier to entry, requiring no professional skills, and adapts to different soil conditions and fertilization needs.

[0020] 5. The use of belt and bevel gear transmission ensures reliable transmission and easy synchronization. The meshing of the worm gear and worm wheel reduces the number of parts, making assembly faster and maintenance costs lower. Attached Figure Description

[0030] The second traveling unit includes a second rotating shaft 11. A motor 10 is fixed on one of the fixed frames 7. The output shaft of the motor 10 is concentrically fixedly connected to the second rotating shaft 11. The second rotating shaft 11 is rotatably connected to the other fixed frame 7. Two second rollers 9 are concentrically fixed on the second rotating shaft 11.

[0031] The rear end of the mounting frame 1 is fixed with a handrail 3, and the lower end of the handrail 3 is fixed with two fixed rods 4. The lower ends of the two fixed rods 4 are connected through the first walking unit.

[0032] The first traveling unit includes a first rotating shaft 5, on which two first rollers 6 are concentrically fixed.

[0033] A housing 2 is fixed on the mounting frame 1. A discharge pipe 8 is fixedly connected to both the left and right sides of the lower end of the housing 2. A cylinder 23 is fixedly connected to the discharge end of the discharge pipe 8. The axial direction of the cylinder 23 is parallel to the traveling direction of the device. An outlet is opened on the side of the cylinder 23 opposite to the discharge pipe 8. A third rotating shaft 13 is concentrically rotatably arranged inside the cylinder 23. Multiple levers 12 are evenly distributed and fixed to the outer circumference of the third rotating shaft 13. The end of the lever 12 away from the third rotating shaft 13 slides in contact with the inner edge of the cylinder 23. A transmission rod is rotatably arranged between the two fixed frames 7. The transmission rod is connected to the second traveling unit through the first transmission assembly.

[0034] The first transmission assembly includes a belt 17, a drive wheel 19 concentrically fixed on the second rotating shaft 11, and a driven wheel 18 concentrically fixed on the transmission rod. The drive wheel 19 and the driven wheel 18 are located on the same side. A clearance groove 16 is provided in the fixing frame 7 on one side of the drive wheel 19 and the driven wheel 18. The belt 17, the drive wheel 19 and the driven wheel 18 are located in the clearance groove 16. The drive wheel 19 and the driven wheel 18 are connected by the belt 17.

[0035] The transmission rod is connected to the third rotating shaft 13 via the second transmission assembly.

[0036] The transmission rod is a fourth rotating shaft 15, which is rotatably connected to two fixed frames 7. The second transmission assembly includes two second bevel gears 20 concentrically fixed on the fourth rotating shaft 15. A first bevel gear 14 is concentrically fixed on the third rotating shaft 13.

In this embodiment, the second transmission assembly has fewer parts, making the assembly process more convenient and faster.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
