Description

Technical Field

[0001] This utility model relates to the technical field of agricultural planting equipment, and in particular to a portable sowing and fertilizing device. Background Technology

[0002] In agricultural planting, sowing and fertilization are crucial steps in crop growth and yield, but existing related devices have many shortcomings. Traditional fertilization devices and seeders are mostly fixed installations or large mechanical structures, with relatively limited functionality, supporting only one of the two tasks. This limitation forces farmers to frequently replace equipment to meet different agricultural needs, significantly increasing equipment purchase costs and reducing operational efficiency, failing to meet the urgent demands of modern agriculture for multifunctionality and high efficiency. Furthermore, some mechanized devices rely on electric motors, resulting in high energy consumption, and their complex mechanical and electronic structures greatly increase the difficulty and cost of maintenance. These factors make it difficult for such equipment to be widely adopted by small-scale farmers, further limiting its application in small-scale farming and economically underdeveloped areas. Therefore, there is an urgent need to develop a portable sowing and fertilization agricultural device to effectively solve the above problems, improve agricultural production efficiency, and reduce farmers' operating costs.

[0030] Reference Figures 1 to 3 According to an embodiment of the present invention, the portable sowing and fertilizing device includes a material cylinder 10 and a movable pull rod 20. The material cylinder 10, from top to bottom, includes several material bins 11, several metering bins 12, and several discharge bins 13. The material bins 11 and metering bins 12 are separated by a first partition 14, and the metering bins 12 and discharge bins 13 are separated by a second partition 15. The first partition 14 and the second partition 15 are respectively provided with a first discharge hole 141 and a second discharge hole 151. The material bins 11 are connected to the metering bins 12 through the first discharge hole 141, and the metering bins 12 are connected to the discharge bins 13 through the second discharge hole 151. The upper end of the material bins 11 is provided with a feed inlet 111. The lower end of the hopper 13 is provided with a discharge port 112; the movable pull rod 20 is movably disposed in the hopper 11 and the metering hopper 12. The movable pull rod 20 passes through the first discharge hole 141 and the second discharge hole 151 in sequence. The lower part of the movable pull rod 20 is provided with a first sealing part 21 and a second sealing part 22. The first sealing part 21 is located on one side of the first partition 14, and the second sealing part 22 is located on one side of the second partition 15. The first sealing part 21 is used to block or open the first discharge hole 141, and the second sealing part 22 is used to block or open the second discharge hole 151.

[0031] This portable sowing and fertilizing device offers numerous significant benefits. In terms of functional integration, it combines sowing and fertilizing functions into one unit, effectively solving the problem of single-function traditional fertilizing devices and seeders. Farmers no longer need to frequently change equipment for different agricultural needs, greatly saving the cost of purchasing multiple devices and reducing the time spent on equipment replacement, significantly improving operational efficiency and fully meeting the urgent needs of modern agriculture for multifunctional agricultural devices. Regarding energy consumption and maintenance, this device does not rely on a motor drive, avoiding high energy consumption. Furthermore, its relatively simple structure, without complex mechanical and electronic components, significantly reduces the device's failure rate. Even if minor problems occur, maintenance is relatively simple, requiring no professional technicians or specific equipment, reducing maintenance difficulty and costs, and facilitating widespread application by small-scale farmers and in economically underdeveloped areas. From an operational convenience perspective, the movable lever 20 design makes sowing and fertilizing operations simpler and more flexible. Farmers can control the sealing and opening of the first and second sealing parts 21 and 22 of the first and second material discharge holes 141 and 151 by simply pulling the movable lever 20, thereby realizing the quantitative feeding of materials. The operation process is easy to understand, reducing the requirements for farmers' operating skills and improving the accuracy and stability of the operation.

[0032] The portable seeding and fertilizing device will be described in detail below with reference to specific embodiments.

[0033] This portable seeding and fertilizing device mainly consists of two parts: a feed cylinder 10 and a movable pull rod 20. The feed cylinder 10 is made of lightweight, high-strength plastic and is cylindrical in shape for easy handling and carrying. The feed cylinder 10 is divided into three parts from top to bottom: several feed bins 11, several metering bins 12, and several discharge bins 13. The feed bins 11 and metering bins 12 are separated by a first partition 14, and the metering bins 12 and discharge bins 13 are separated by a second partition 15. The first partition 14 and the second partition 15 have a first discharge hole 141 and a second discharge hole 151, respectively. The feed bins 11 are connected to the metering bins 12 through the first discharge hole 141, and the metering bins 12 are connected to the discharge bins 13 through the second discharge hole 151. One end of the feed bin 11 has a feed inlet 111 for adding seeds or fertilizer; one end of the discharge bins 13 has a discharge outlet 112 for discharging materials (fertilizer or seeds) into the soil. The movable pull rod 20 is movably disposed in the feed cylinder 10, passing sequentially through the first discharge hole 141 and the second discharge hole 151. One end of the movable pull rod 20 is provided with a first sealing part 21 and a second sealing part 22, both located in the metering chamber 12. The first sealing part 21 and the second sealing part 22 are made of rubber, providing good sealing performance. The first sealing part 21 is used to seal or open the first discharge hole 141, and the second sealing part 22 is used to seal or open the second discharge hole 151.

[0034] Before actual use, seeds or fertilizers are added to the hopper 11 through the inlet 111 at one end. When sowing or fertilizing is required, the farmer holds the feed cylinder 10 and aligns the outlet 112 with the location where the material needs to be added. In the initial state, the first sealing part 21 blocks the first discharge hole 141, and the second sealing part 22 opens the second discharge hole 151. At this time, the material in the hopper 11 cannot enter the metering hopper 12, but the small amount of material remaining in the metering hopper 12 can be discharged through the second discharge hole 151 and the outlet 112. When a metered amount of material needs to be added, the farmer pulls the movable lever 20 up or down, causing the first sealing part 21 to move away from the first discharge hole 141, opening the first discharge hole 141, while the second sealing part 22 moves upward to block the second discharge hole 151. At this time, the material in the hopper 11 enters the metering hopper 12 through the first discharge hole 141. Since the volume of the metering hopper 12 is fixed, the amount of material entering the metering hopper 12 each time is relatively stable, thus achieving the metering function. When the metering hopper 12 is full of material, the farmer pushes the movable lever 20 downwards or upwards, causing the first sealing part 21 to seal the first discharge hole 141 again, while the second sealing part 22 moves away from the second discharge hole 151, opening the second discharge hole 151. The material in the metering hopper 12 is then released into the soil through the second discharge hole 151 and the outlet 112, completing one sowing or fertilization operation. By repeating the above operation of pulling and pushing the movable lever 20, sowing or fertilization operations can be carried out continuously. The operation is simple and quick, and can meet the needs of different agricultural operations.

[0035] Reference Figures 1 to 3 In some embodiments of this utility model, the portable sowing and fertilizing device further includes several partition plates 30, which are disposed in the material cylinder 10 and fixedly connected to the material cylinder 10. The material cylinder 10 is divided into several material bins 11 and several quantitative bins 12 by the partition plates 30. Several movable pull rods 20 are provided, and the several movable pull rods 20 are respectively inserted into the material bins 11 and the quantitative bins 12.

[0036] In this portable sowing and fertilizing device, to further enhance its functional versatility and practicality, and to meet the requirements of simultaneous operation of multiple materials under different crop or fertilization sowing needs, several partition plates 30 are provided. These partition plates 30 are made of stainless steel, possessing a certain strength and stability to ensure that they will not deform or be damaged during device use. The partition plates 30 are carefully placed inside the material cylinder 10 and are securely fixed to the material cylinder 10 through snap-fit ​​connections. Through the reasonable layout of these partition plates 30, the material cylinder 10 is effectively divided into several independent material bins 11 and several independent metering bins 12. For example, in a practical application scenario, if it is necessary to simultaneously sow and fertilize two different types of seeds and one type of fertilizer, two partition plates 30 can be used to divide the material cylinder 10 into three material bins 11, respectively for storing the two types of seeds and one type of fertilizer, and correspondingly, three metering bins 12 can be created to ensure that each material can achieve independent metering control. For example, in a practical application scenario, if it is necessary to sow and fertilize a seed and a fertilizer at the same time, a partition plate 30 can be set up to divide the material cylinder 10 into two material bins 11, which are used to store a seed and a fertilizer respectively. At the same time, two quantitative bins 12 are correspondingly separated to ensure that each material can achieve independent quantitative control.

[0037] To accommodate the multiple hoppers 11 and metering hoppers 12 formed after separation, several movable pull rods 20 are provided. The structure of each movable pull rod 20 is the same as that of the movable pull rod 20 in the above embodiment, all made of stainless steel, and one end is provided with a first sealing part 21 and a second sealing part 22 for sealing or opening the discharge hole. These movable pull rods 20 are respectively inserted into the corresponding hoppers 11 and metering hoppers 12. Specifically, each movable pull rod 20 is sequentially inserted into the first discharge hole 141 between its hopper 11 and metering hopper 12 and the second discharge hole 151 between the metering hopper 12 and the lower discharge hopper 13 (if there is only one total discharge hopper 13, then the discharge structure between it and the metering hopper 12 is used).

[0038] In actual operation, when different materials need to be applied, farmers can operate the corresponding movable lever 20 according to the needs of each material. For example, when applying the first type of seed, pulling the movable lever 20 corresponding to the seed storage bin 11 opens the first discharge hole 141 on the movable lever 20, allowing the seed to enter the corresponding metering bin 12. After the metering bin 12 is full, pushing the movable lever 20 opens the second discharge hole 151 on the second sealing part 22, and the seed is then applied to the soil through the discharge port 112. Similarly, other materials are applied in the same way. This design allows farmers to simultaneously and precisely sow and fertilize multiple materials, greatly improving operational efficiency. Moreover, the application amount of each material can be controlled independently, better meeting the growth needs of different crops and providing a more convenient and efficient solution for agricultural production. In a practical test case, using the device with multiple hoppers 11, metering bins 12, and movable levers 20 for multi-material seeding and fertilization operations, compared to the traditional method of using single-function devices sequentially, the operation time was reduced by nearly half, and the accuracy and uniformity of material delivery were significantly improved. It is understandable that the multiple movable levers 20 can also be pulled simultaneously, causing the first sealing part 21 and the second sealing part 22 in each hopper 11 or each metering bin 12 to simultaneously open or close the first discharge hole 141 and the second discharge hole 151, thereby simultaneously performing precise metering and fertilization of multiple materials.

[0039] Reference Figures 1 to 3 In some embodiments of this utility model, a partition plate 30 is provided, which is disposed in the material cylinder 10. The material bin 11 is divided into a seed bin and a fertilizer bin by the partition plate 30, and the quantitative bin 12 is divided into a quantitative seed bin and a quantitative fertilizer bin by the partition plate 30. The movable pull rod 20 is respectively inserted into the material bin 11 and the quantitative bin 12.

[0040] In this portable seeding and fertilizing device, when only one partition plate 30 is used, this partition plate 30 is also made of high-strength and corrosion-resistant stainless steel to ensure that no chemical reaction occurs during long-term contact with seeds and fertilizers, thus affecting the quality of the materials, while also ensuring the stability of its own structure. This partition plate 30 is precisely installed inside the material cylinder 10. A raised structure on the edge of the partition plate 30 tightly engages with the corresponding groove on the inner wall of the material cylinder 10, achieving a stable and fixed connection and preventing displacement of the partition plate 30 during use. Through the reasonable arrangement of this partition plate 30, the material cylinder 10 is effectively divided into two independent parts: a seed chamber and a fertilizer chamber. The seed chamber is used to store various crop seeds, and its size can be designed according to actual planting needs and common seed volumes to ensure sufficient seed capacity. The fertilizer chamber is used to store fertilizers suitable for the growth of the corresponding crops and also has a reasonable volume. Simultaneously, corresponding to the seed and fertilizer chambers, the metering chamber 12 is also divided into a metered seed chamber and a metered fertilizer chamber. The volume of the quantitative seed bins and quantitative fertilizer bins is scientifically set according to agricultural technical parameters such as crop planting density and fertilizer application rate to ensure that the number of seeds and fertilizers applied each time meets the requirements of agricultural production.

[0041] There are two movable levers 20, corresponding to the combinations of the seed bin, the quantitative seed bin, the fertilizer bin, and the quantitative fertilizer bin, respectively. The structure of each movable lever 20 is consistent with the aforementioned embodiment, made of lightweight and flexible stainless steel, with a first sealing part 21 and a second sealing part 22 at one end. These two movable levers 20 are respectively inserted into the corresponding hopper 11 and quantitative bin 12. Specifically, the movable lever 20 for seed dispensing is sequentially inserted through the first discharge hole 141 between the seed bin and the quantitative seed bin, and the second discharge hole 151 between the quantitative seed bin and the lower discharge bin 13; the movable lever 20 for fertilizer dispensing is sequentially inserted through the first discharge hole 141 between the fertilizer bin and the quantitative fertilizer bin, and the second discharge hole 151 between the quantitative fertilizer bin and the lower discharge bin 13.

[0042] In practical agricultural production, farmers first add seeds and fertilizer to the corresponding silos through the inlets 111 above the seed silo and fertilizer silo, respectively. When sowing and fertilization are required, for seed dispensing, the farmer pulls the movable lever 20 corresponding to the seed silo, causing the first sealing part 21 to open the first discharge hole 141, allowing seeds to fall from the seed silo into the quantitative seed silo. Once the quantitative seed silo is full, the farmer pushes the movable lever 20, causing the second sealing part 22 to open the second discharge hole 151, and the seeds are then released into the soil through the discharge port 112. For fertilizer dispensing, the operation is the same as for seed dispensing; the farmer pulls the movable lever 20 corresponding to the fertilizer silo to control the falling and dispensing of fertilizer. This design allows farmers to complete both seed sowing and fertilizer application simultaneously in one operation, greatly improving work efficiency and reducing the time and labor intensity spent working back and forth in the field.

[0043] Reference Figures 1 to 2 In some embodiments of this utility model, the portable sowing and fertilizing device also includes a handle 31. The handle 31 is set at the upper end of the partition plate 30 and located above the material cylinder 10. The upper end of the movable pull rod 20 is connected and fixed by a crossbar 23. The partition plate 30 is provided with a clearance groove 32. The crossbar 23 can pass through the clearance groove 32 and connect two movable pull rods 20 respectively.

[0044] To further enhance the ease and comfort of operation, a handle 31 has been added to this portable seeding and fertilizing device. The handle 31 features an ergonomic arc design, with both ends securely bolted to the upper end of the partition plate 30 and positioned directly above the feed cylinder 10. This arrangement allows farmers to naturally grip the handle 31 while operating the device, reducing hand fatigue. It also facilitates the insertion of the lower end of the feed bin 13 into the soil. Regarding the movable levers 20, the upper ends of the two levers 20, corresponding to the seed bin and fertilizer bin respectively, are connected and fixed by a crossbar 23. The crossbar 23 is made of the same stainless steel as the movable levers 20. A clearance groove 32 is specially provided on the partition plate 30. The shape and size of the clearance groove 32 are adapted to the crossbar 23. Its width is slightly larger than the diameter of the crossbar 23, and its depth is reasonably designed according to the connection position of the crossbar 23 and the stroke of the movable pull rod 20 to ensure that the crossbar 23 can be smoothly inserted into the clearance groove 32 and will not interfere with the partition plate 30 during the movement.

[0045] In practical use, when farmers need to operate both movable levers 20 simultaneously for seed and fertilizer application, they only need to grasp the crossbar 23 and pull or push it. Since the crossbar 23 connects the two movable levers 20 into one unit, the operation is more coordinated and unified, avoiding the potential asynchronous problems that might occur when operating the two movable levers 20 separately. For example, at the start of sowing and fertilization, the farmer grasps the crossbar 23 and pulls it upwards. At this time, both movable levers 20 move upwards simultaneously, and the corresponding first sealing part 21 opens the first discharge hole 141, allowing seeds to fall from the seed hopper into the quantitative seed hopper, and fertilizer to fall from the fertilizer hopper into the quantitative fertilizer hopper. When the quantitative hopper 12 is full, the farmer pushes the crossbar 23 downwards, and the two movable levers 20 move downwards accordingly. The second sealing part 22 opens the second discharge hole 151, and seeds and fertilizer are respectively placed into the soil through the discharge port 112.

[0046] According to some embodiments of the present invention, the diameter of the first discharge hole 141 and the diameter of the second discharge hole 151 are both larger than the diameter of the movable pull rod 20, and the diameter of the first sealing part 21 and the diameter of the second sealing part 22 are both larger than the diameter of the first discharge hole 141 and the diameter of the second discharge hole 151.

[0047] In this portable seeding and fertilizing device, the design of the apertures of the first and second discharge holes 141 and 151, as well as the diameter settings of the first and second sealing parts 21 and 22 on the movable pull rod 20, are precisely and reasonably considered. The aperture sizes of the first and second discharge holes 141 and 151 are determined based on the particle size of seeds and fertilizers and the required flow rate in actual agricultural production. After extensive experiments and data analysis, the apertures of both the first and second discharge holes 141 and 151 are set to be a certain value larger than the diameter of the movable pull rod 20. For example, when the diameter of the movable pull rod 20 is 1 cm, the apertures of the first and second discharge holes 141 and 151 are set to 1.25 cm. This design ensures that the movable pull rod 20 can move smoothly up and down when passing through the first and second discharge holes 141 and 151, without jamming due to excessively small apertures, thus guaranteeing the flexibility and stability of the device during operation.

[0048] Both the first sealing part 21 and the second sealing part 22 are larger than the diameters of the first discharge hole 141 and the second discharge hole 151. For example, when the diameters of the first discharge hole 141 and the second discharge hole 151 are 2 cm, the diameters of the first sealing part 21 and the second sealing part 22 are set to 2.1 cm. This dimensional relationship allows the first sealing part 21 to tightly seal the first discharge hole 141 when the movable lever 20 is in its initial position, preventing seeds or fertilizer from falling from the hopper 11 into the metering hopper 12; when material needs to be added, pulling the movable lever 20 causes the first sealing part 21 to move away from the first discharge hole 141, allowing the material to pass through smoothly. Similarly, after the metering bin 12 is filled with material, the movable lever 20 is pushed to make the second sealing part 22 tightly seal the second discharge hole 151 to prevent the material from leaking before reaching the discharge position; when the appropriate discharge position is reached, the movable lever 20 is pushed again to make the second sealing part 22 leave the second discharge hole 151, and the material is accurately discharged into the soil through the discharge port 112.

[0049] In actual field operation tests, during repeated sowing and fertilization operations, the movable lever 20 moved smoothly in the first and second material discharge holes 141 and 151 without any jamming or obstruction, ensuring the normal operation of the device. Simultaneously, the first and second sealing parts 21 and 22 effectively sealed the material discharge holes, preventing material leakage during non-dispensing stages. This allowed for precise control of seed and fertilizer dispensing amounts, significantly improving the accuracy and uniformity of sowing and fertilization, providing a more stable and suitable environment for crop growth, and contributing to increased crop yield and quality.

[0050] Reference Figures 1 to 2 as well as Figure 4 In some embodiments of this utility model, a fixed frame 16 is provided in the hopper 11, and the movable pull rod 20 can be inserted into the fixed frame 16. In this portable sowing and fertilizing device, in order to further improve the stability of the movable pull rod 20 in the movement within the hopper 11 and ensure that the device can accurately control the material delivery during the sowing and fertilizing process, a fixed frame 16 is specially provided in the hopper 11. The fixed frame 16 is made of high-strength and flexible engineering plastic material. This material can withstand the pressure of seeds and fertilizers in the hopper 11 without being too hard and causing excessive wear to the movable pull rod 20 during frequent movement. At the same time, its flexibility can also buffer the impact force generated when the movable pull rod 20 moves to a certain extent, extending the service life of the device.

[0051] The shape of the fixing frame 16 is designed according to the internal structure of the hopper 11, and is usually frame-like. The corners of the frame are rounded to avoid damage to the movable pull rod 20 from sharp edges. The movable pull rod 20 can be inserted into the fixing frame 16. The diameter of the hole on the fixing frame 16 for the movable pull rod 20 to pass through is precisely calculated and is slightly larger than the diameter of the movable pull rod 20, generally 0.5 to 1 cm larger. This ensures that the movable pull rod 20 can move smoothly up and down in the hole, while effectively limiting the range of sway of the movable pull rod 20 and preventing it from deviating during movement. In actual operation, when the farmer pulls or pushes the movable pull rod 20 to perform seed or fertilizer dispensing operations, the movable pull rod 20, under the constraint of the fixing frame 16, always moves along a predetermined straight trajectory. For example, during sowing, the farmer pulls the movable lever 20, which rises steadily under the guidance of the fixed frame 16, allowing the first sealing part 21 to accurately open the first discharge hole 141, and the seeds fall smoothly into the metering chamber 12; after the metering chamber 12 is full, the farmer pushes the movable lever 20, which then descends steadily under the action of the fixed frame 16, and the second sealing part 22 accurately opens the second discharge hole 151, allowing the seeds to be accurately placed into the soil through the discharge port 112.

[0052] Reference Figures 1 to 2 In some embodiments of this utility model, a circular, flared first guide section 1111 is provided at the upper end of the hopper 11, and the guide section is connected to the feed inlet 111. In this portable sowing and fertilizing device, to facilitate farmers to add seeds and fertilizer to the hopper 11 more efficiently and accurately, a circular, flared first guide section 1111 is specially provided at the upper end of the hopper 11. The first guide section 1111 is made of the same plastic material as the hopper 11. This material not only has good durability and can withstand the impact and friction in daily use, but also has a certain degree of corrosion resistance, which can prevent damage caused by long-term contact with seeds, fertilizers, and moisture and chemicals in the external environment, ensuring the long-term stable use of the device. Specifically, the first guide section 1111 is circular and flared in shape, and its flaring angle is carefully designed, generally set between 60° and 90°, and its circular outer diameter is no more than 0.5 meters. This angled design ensures that the feed guide has a sufficiently large opening area, facilitating farmers to quickly pour in materials, while also allowing the materials to smoothly converge at the inlet 111 during the pouring process, reducing spillage and waste. For example, when farmers add seeds to the hopper 11 using a shovel or bag, the larger opening angle makes it easier for the seeds to enter the feed guide, and guided by the inner wall of the feed guide, the seeds can accurately fall into the hopper 11 through the inlet 111, greatly improving the efficiency of adding materials.

[0053] Reference Figures 1 to 3In some embodiments of this utility model, the middle part of the discharge bin 13 is a second guide part 1121 with a circular opening, and the lower part of the discharge bin 13 is a cylindrical insertion part 131. The insertion part 131 is connected to the second guide part 1121, and the lower end of the insertion part 131 is provided with a discharge port 112. The lower end of the insertion part 131 is provided with an oblique opening.

[0054] In this portable seeding and fertilizing device, the middle of the feeding bin 13 is designed as a second guide section 1121 with a circular opening. This second guide section 1121 is made of the same plastic material as the feeding bin 13, which has a smooth inner wall surface, effectively reducing friction during material passage and ensuring smooth material flow. The circular opening design is precisely calculated, with an opening angle generally between 45° and 60°. This angle ensures that when material falls from the metering bin 12 into the second guide section 1121, it quickly converges along the inner wall without accumulating at the opening due to an excessively large angle. For example, when seeds fall from the metering seed bin into the second guide section 1121, the seeds slide down the inner wall of the opening, avoiding blockage in the middle. The lower part of the feeding bin 13 is designed as a cylindrical insertion part 131, which is connected to the second guide section 1121 via an integral injection molding process. The diameter of the insertion part 131 is reasonably set according to the actual sowing and fertilization needs and the size of the discharge port 112. It is generally slightly smaller than the minimum diameter of the second guide part 1121 at the closing point to ensure that the material can smoothly transition from the second guide part 1121 to the insertion part 131. The lower end of the insertion part 131 is provided with the discharge port 112, which is the key part for the final placement of seeds and fertilizer into the soil. To further improve the accuracy and efficiency of placement, the lower end of the insertion part 131 is set at an angle. The angle of the angle is usually between 30° and 60°, the diameter of the discharge port 112 is not less than 2 cm, the bottom uses a 60° angle, and the fixed length of the insertion part 131 is 25 to 35 cm, allowing for more concentrated placement to the predetermined location. For example, in fertilization operations, after the fertilizer is discharged from the angled discharge port 112, it can penetrate deeper into the soil, improving fertilizer utilization.
