Description

Technical Field

[0001] This invention relates to the field of fertilization equipment technology, specifically to an intelligent fertilization device for crop cultivation. Background Technology

[0002] Intelligent fertilization devices for crop cultivation are modern agricultural equipment that integrates sensor technology, the Internet of Things, and automated control. They can achieve precise and efficient fertilization operations based on crop growth needs, soil conditions, and other factors, thereby improving fertilizer utilization, reducing resource waste and environmental pollution, and contributing to the development of smart agriculture.

[0003] Patent CN221829458U relates to a crop fertilization device, including a storage tank and a base. The storage tank contains a stirring device and a filter screen. A partition is located below the filter screen, and the partition has a discharge port. A rotating disk is located below the storage tank, and the rotating disk has a through hole that mates with the discharge port. A protrusion is located on the side of the rotating disk near the through hole. An inclined weighing device is located below the rotating disk, and a baffle connected to the storage tank wall by a spring is located on the lower side of the inclined weighing device. The stirring device, rotating disk, and inclined weighing device are all included. All the weighing devices are electrically connected to the controller; the base is located below the storage box, and a moving device is also located below the base. This device uses an inclined plane weighing device to control the amount of fertilizer applied each time, thereby improving the accuracy and stability of fertilization, reducing waste, increasing crop absorption efficiency, and reducing environmental pollution. However, during the fertilization process, because the discharge port of this device is single and fixed, it is difficult for the fertilizer to fall accurately on the roots and stems of crops when facing planting ditches of different heights. Therefore, an intelligent fertilization device for crop planting is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an intelligent fertilization device for crop planting, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an intelligent fertilization device for crop planting, including a frame, a fixed frame fixedly connected to the inner wall of the frame, a storage bin fixedly connected to the inner wall of the fixed frame, a fixed plate fixedly connected to the inner wall of the storage bin, a threaded rod rotatably connected to the inner wall of the fixed plate, a funnel fixedly connected to the bottom of the storage bin, a U-shaped plate threadedly connected to the circumferential surface of the threaded rod rotatably, a limit rod fixedly connected to the inner wall of the storage bin, a metering plate fixedly connected to the bottom of the U-shaped plate, a beam plate fixedly connected to the inner wall of the fixed frame, a threaded rod rotatably connected to the inner wall of the fixed frame, a lifting frame threadedly connected to the circumferential surface of the threaded rod rotatably, a movable opening fixedly connected to the front of the lifting frame, a compaction mechanism for improving the fertilizer absorption effect of crops provided on the inner wall of the frame, a discharge mechanism for accelerating the discharge speed provided on the inner wall of the storage bin, and a rotating shaft rotatably connected to the inner wall of the frame. During the fertilization process, the metering plate moves downwards, thereby... The system closes the outlet of the funnel to allow for quantitative discharge. The discharge volume can be adjusted by changing the forward and reverse rotation of the motor, enabling targeted fertilization based on the specific fertilizer requirements of different crops. A motor is mounted on the top of the first threaded rod, driving its rotation. The circumferential surface of the limiting rod slides against the inner wall of the U-shaped plate. The inner wall of the storage hopper contacts the surface of the metering plate, which controls the fertilizer flow. The surface of the movable opening slides against the inner wall of the funnel. The top of the beam plate is fixedly connected to the inner wall of the storage hopper. A motor is mounted on the top of the second threaded rod, driving its rotation. The lifting frame controls the height of the movable opening to adapt to different ditch heights, ensuring even distribution of fertilizer at the plant roots and preventing fertilizer from falling onto plant leaves and being carried away by wind or water, thus avoiding waste. Adjusting the movable opening ensures fertilizer enters the soil, reducing fertilizer loss.

[0006] Preferably, the compaction mechanism includes a connecting plate fixedly connected to the bottom of the lifting frame. An elastic telescopic plate is fixedly connected to the left side of the connecting plate. A slanted shovel is fixedly connected to the inner wall of the telescopic end of the elastic telescopic plate. A chamfered block is fixedly connected to the bottom of the telescopic end of the elastic telescopic plate. A double-acting screw is rotatably connected to the inner wall of the connecting plate. An adjusting wheel is fixedly connected to the circumferential surface of the double-acting screw. A rounded corner plate is fixedly connected to the inner wall of the frame. A sliding rod is slidably connected to the inner wall of the rounded corner plate via a spring. A compaction block is fixedly connected to the bottom of the sliding rod. A three-plate ring is fixedly connected to the circumferential surface of the rotating shaft. A force-bearing plate is fixedly connected to the rear of the compaction block. During fertilization, the fertilizer can fall onto the crops... When applying fertilizer to the plant roots, the slanted shovel can push the soil from the side of the ditch to the vicinity of the fertilizer application point. The distance between the slanted shovels can be freely adjusted to adapt to ditches of different widths, ensuring that the slanted shovels align with each other on the sloping surface of the ditch. This ensures that the soil is pushed to the crop roots. The inner wall of the chamfered block is threaded to the circumferential surface of the bidirectional screw. The slanted shovel is used to push the soil from the side of the ditch to the vicinity of the plant roots. The surface of the three-plate ring contacts the top of the force-bearing plate. During soil covering, it can compress the soil after fertilizer application, helping to mix the fertilizer more evenly with the soil and ensuring better contact between the fertilizer and nutrients and microorganisms in the soil, thereby improving fertilizer utilization efficiency.

[0007] Preferably, the discharge mechanism includes a second movable rod, which is slidably connected to the inner wall of the movable opening. A V-shaped plate is fixedly connected to the circumferential surface of the second movable rod. An angled plate is fixedly connected to the front of the compaction block. A fixed rod is fixedly connected to the inner wall of the storage hopper. A pusher plate is slidably connected to the circumferential surface of the fixed rod. A rotating plate is rotatably connected to the rear of the pusher plate. A hinge block is fixedly connected to the front of the U-shaped plate. During soil compaction, this ensures that fertilizer is continuously and stably discharged from the device during fertilization. The system facilitates fertilizer application, preventing interruptions due to clogging and ensuring precision and efficiency. It ensures fertilizer is evenly distributed across the soil surface during each application, guaranteeing a balanced nutrient supply to the crop. The bottom of the pusher plate contacts the inner wall of the storage hopper, and the inner wall of the hinge block is rotatably connected to the rear of the rotating plate. This allows for effective utilization of all fertilizer during application, preventing waste. Furthermore, it assists in fertilizer discharge during sowing, preventing clogging at the discharge port.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This intelligent fertilization device for crop cultivation, through the coordinated operation of a frame, a fixed frame, a storage bin, a fixed plate, a threaded rod (first), a funnel, a U-shaped plate, a limit rod, a metering plate, a beam plate, a threaded rod (second), a lifting frame, and a movable opening, allows for targeted fertilization based on the fertilizer requirements of different crops. It ensures that the fertilizer is evenly distributed at the plant roots and stems, preventing fertilizer from falling onto plant leaves and being carried away by wind or water, thus avoiding waste. Adjusting the movable opening ensures that fertilizer enters the soil, reducing fertilizer loss.

[0009] 2. This intelligent fertilization device for crop planting, through the coordinated operation of connecting plates, elastic telescopic plates, shovels, chamfered blocks, bidirectional screws, and adjusting wheels, allows the shovels to push the soil on the side of the ditch to the vicinity of the fertilizer application point when the fertilizer falls on the crop rootstock. The distance between the shovels can be freely adjusted to adapt to ditches of different widths, ensuring that the shovels are aligned with each other on the slope of the ditch, thus guaranteeing that the soil is pushed to the crop rootstock.

[0010] 3. This intelligent fertilization device for crop planting, through the coordinated operation of rounded corner plates, sliding rods, compaction blocks, three-plate rings, force plates, and rotating shafts, can compress the soil after sowing fertilizer during the soil covering process, which helps to mix the fertilizer more evenly with the soil, ensures better contact between the fertilizer and nutrients and microorganisms in the soil, and thus improves the utilization efficiency of fertilizer.

[0011] 4. This intelligent fertilization device for crop planting, through the coordinated operation of the moving rod, V-shaped plate, and inclined plate, ensures that fertilizer is continuously and stably discharged from the device during the soil compaction process, avoiding fertilization interruption due to fertilizer blockage. This helps to ensure the accuracy and efficiency of fertilization, ensuring that fertilizer can be evenly covered on the soil surface each time, and ensuring a balanced supply of nutrients to the crops.

[0012] 5. This intelligent fertilization device for crop planting, through the coordinated operation of the fixed rod, the pusher plate, the rotating plate and the hinge block, can effectively utilize all fertilizers during the fertilization process and avoid fertilizer waste. At the same time, it can assist in the discharge of fertilizers during sowing and prevent fertilizers from clogging the discharge port. Attached Figure Description

[0015] 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.

[0016] Please see Figures 1-7One embodiment of the present invention is: an intelligent fertilization device for crop planting, comprising a frame 1, a fixing frame 2 fixedly connected to the inner wall of the frame 1, a storage bin 3 fixedly connected to the inner wall of the fixing frame 2, a fixing plate 4 fixedly connected to the inner wall of the storage bin 3, a threaded rod 5 rotatably connected to the inner wall of the fixing plate 4, a funnel 6 fixedly connected to the bottom of the storage bin 3, a U-shaped plate 7 threadedly connected to the circumferential surface of the threaded rod 5, a limit rod 8 fixedly connected to the inner wall of the storage bin 3, and the bottom of the U-shaped plate 7... A metering plate 9 is fixedly connected to the inner wall of the fixed frame 2. A beam plate 10 is fixedly connected to the inner wall of the fixed frame 2. A threaded rod 11 is rotatably connected to the inner wall of the fixed frame 2. A lifting frame 12 is threadedly connected to the circumferential surface of the threaded rod 11. A movable opening 13 is fixedly connected to the front of the lifting frame 12. A compaction mechanism 14 is provided on the inner wall of the frame 1 to improve the fertilizer absorption effect of crops. A discharge mechanism 15 is provided on the inner wall of the storage hopper 3 to speed up the discharge speed. A rotating shaft 16 is rotatably connected to the inner wall of the frame 1. During the fertilization process, the storage hopper 3 is first filled with fertilizer. Then, the motor is started and the threaded rod 5 rotates in both directions. The rotation of the threaded rod 5 drives the U-shaped plate 7 to move up and down through the threaded groove on its surface. The movement of the U-shaped plate 7 drives the metering plate 9 to move up and down. When the metering plate 9 moves upward, it opens the outlet of the funnel 6. At this time, the fertilizer will flow out from the funnel 6 and the movable opening 13, and then flow to the vicinity of the crop roots to fertilize the crop. When the motor drives the threaded rod 5 to reverse, the metering plate 9 will move downward, which will close the outlet of the funnel 6 so that the fertilizer can be discharged in a metered manner. At the same time, the amount of fertilizer discharged each time can be changed by adjusting the time of forward and reverse rotation of the motor, so that targeted fertilization can be carried out according to the fertilizer needs of different crops. A motor is installed at the top of the threaded rod 5, and the threaded rod 5 will be driven by the motor to rotate. The circumferential surface of the limiting rod 8 is slidably connected to the inner wall of the U-shaped plate 7. The inner wall of the storage bucket 3 is in contact with the surface of the metering plate 9, and the metering plate 9 is used to control the flow of fertilizer. The surface of the movable port 13 is slidably connected to the inner wall of the funnel 6. The top of the beam plate 10 is fixedly connected to the inner wall of the storage bucket 3. A motor is installed at the top of the threaded rod 11, and the threaded rod 11 will be driven by the motor to rotate. The lifting frame 12 is used to control the height of the movable port 13 to adapt to ditches of different heights. When facing planting ditches of different depths, the motor starts and drives the threaded rod 11 to rotate. The rotation of the threaded rod 11 drives the lifting frame 12 to adjust up and down through the threaded groove on its surface. The movement of the lifting frame 12 drives the movable opening 13 to move up and down, thereby ensuring that the fertilizer can be evenly distributed at the plant roots and stems, while preventing the fertilizer from falling on the plant leaves and being carried away by wind or water, resulting in waste. By adjusting the movable opening 13, the fertilizer is ensured to enter the soil, reducing fertilizer loss.

[0017] Working principle: During fertilization, the storage hopper 3 is first filled with fertilizer. Then, the motor is started and the screw rod 5 rotates in both directions. When the metering plate 9 moves upward, the outlet of the funnel 6 is opened, and the fertilizer flows out from the funnel 6 and the movable port 13 to fertilize the crops. When the motor drives the screw rod 5 to rotate in reverse, the amount of fertilizer discharged each time can be changed by adjusting the time of the motor's forward and reverse rotation. When facing planting ditches of different depths, the motor starts and drives the screw rod 11 to rotate, which can ensure that the fertilizer can be evenly distributed at the plant roots and stems, while avoiding fertilizer falling on the plant leaves.

[0018] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the compaction mechanism 14 includes a connecting plate 141, which is fixedly connected to the bottom of the lifting frame 12. An elastic telescopic plate 142 is fixedly connected to the left side of the connecting plate 141. A slanted shovel 143 is fixedly connected to the inner wall of the telescopic end of the elastic telescopic plate 142. A chamfer block 144 is fixedly connected to the bottom of the telescopic end of the elastic telescopic plate 142. A two-way screw 145 is rotatably connected to the inner wall of the connecting plate 141. An adjusting wheel 146 is fixedly connected to the circumferential surface of the two-way screw 145. A rounded corner plate 147 is fixedly connected to the inner wall of the frame 1. A sliding rod 148 is slidably connected to the inner wall of the rounded corner plate 147 by a spring. A compaction block 149 is fixedly connected to the bottom of the sliding rod 148. A three-plate ring 1410 is fixedly connected to the circumferential surface of the rotating shaft 16. A force-bearing plate 1411 is fixedly connected to the rear of the compaction block 149. During fertilization, the frame 1 moves forward, causing the fixed frame 2 to move forward. The movement of the fixed frame 2 causes the threaded rod 11 to move forward, which in turn causes the lifting frame 12 to move forward. The movement of the lifting frame 12 causes the forward connecting plate 141 to move forward, which in turn causes the elastic telescopic plate 142 to move forward. The movement of the elastic telescopic plate 142 causes the shovel 143 to move forward. Thus, when the fertilizer falls on the crop rootstock, the shovel 143 can push the soil on the side of the ditch to the vicinity of the fertilizer application site. At the same time, by twisting the adjusting wheel 146, the double-sided screw 145 can be rotated. The rotation of the double-sided screw 145 drives the telescopic end of the elastic telescopic plate 142 to adjust left and right through the double-sided threaded groove on its surface. This allows for free adjustment of the distance between the shovels 143, making it adaptable to ditches of different widths. This ensures that the shovels 143 can be aligned with each other on the slope of the ditch, ensuring that the soil is pushed to the crop rootstock. The inner wall of the chamfered block 144 is threaded to the circumferential surface of the double-ended screw 145. The slanted shovel 143 is used to push the soil on the side of the ditch to the vicinity of the plant roots. The surface of the three-plate ring 1410 is in contact with the top of the force plate 1411. During the soil covering process, the frame 1 moves, causing the rounded corner plate 147 to move. The movement of the rounded corner plate 147 causes the sliding rod 148 to move, which in turn causes the compaction block 149 to move. As the frame 1 moves, the wheels rotate, causing the rotating shaft 16 to rotate. The rotation of the rotating shaft 16 causes the three-plate ring 1410 to rotate clockwise. The rotation of the three-plate ring 1410 applies a downward squeezing force to the force plate 1411 and moves it downward. The downward movement of the force plate 1411 causes the compaction block 149 to move downward. When the three-plate ring 1410 passes the force plate 1411, the sliding rod 148 is reset by the spring and causes the compaction block 149 to move upward. This allows the soil to be compressed after the fertilizer is applied, which helps to mix the fertilizer more evenly with the soil and ensures better contact between the fertilizer and the nutrients and microorganisms in the soil, thereby improving the fertilizer utilization efficiency.

[0019] Working principle: During fertilization, the frame 1 moves forward, driving the fixed frame 2 to move forward. The movement of the fixed frame 2 drives the threaded rod 11 to move forward, which in turn drives the lifting frame 12 to move forward. The movement of the lifting frame 12 drives the forward connecting plate 141, so that when the fertilizer falls on the crop rootstock, the shovel 143 can push the soil on the side of the ditch to the vicinity of the fertilizer application point. At the same time, the distance between the shovels 143 can be freely adjusted to adapt to ditches of different widths. During soil covering, the movement of the frame 1 drives the rounded corner plate 147 to move. When the three-plate ring 1410 passes over the force plate 1411, the sliding rod 148 will be reset by the spring and drive the compaction block 149 to move upward, thereby squeezing the soil after the fertilizer is applied, which helps to mix the fertilizer more evenly with the soil.

[0020] The discharge mechanism 15 includes a second movable rod 151, which is slidably connected to the inner wall of the movable opening 13. A V-shaped plate 152 is fixedly connected to the circumferential surface of the second movable rod 151. An inclined plate 153 is fixedly connected to the front of the compaction block 149. A fixed rod 154 is fixedly connected to the inner wall of the storage bin 3. A pusher plate 155 is slidably connected to the circumferential surface of the fixed rod 154. A rotating plate 156 is rotatably connected to the rear of the pusher plate 155. A hinge block 157 is fixedly connected to the front of the U-shaped plate 7. During the soil compaction process, the tamping block 149 moves up and down, which drives the inclined plate 153 to move synchronously. The movement of the inclined plate 153 drives the second moving rod 151 to move, and the movement of the second moving rod 151 drives the V-shaped plate 152 to move. When the V-shaped plate 152 moves downward, it pushes out the fertilizer stored inside the movable opening 13, thereby preventing the fertilizer from clogging inside the movable opening 13. This ensures that the fertilizer is continuously and stably discharged from the device during the fertilization process, avoiding fertilization interruption due to fertilizer blockage. This helps to ensure the accuracy and efficiency of fertilization, ensuring that the fertilizer can be evenly covered on the soil surface each time, and ensuring a balanced supply of nutrients to the crops. The bottom of the pusher plate 155 is in contact with the inner wall of the storage bin 3, and the inner wall of the hinge block 157 is rotatably connected to the rear of the rotating plate 156. During fertilization, the upward movement of the U-shaped plate 7 will cause the hinge block 157 to move upward. The upward movement of the hinge block 157 will pull the rotating plate 156 upward. Subsequently, the rotating plate 156 will drive the pusher plate 155 to move backward. The backward movement of the pusher plate 155 will push the fertilizer accumulated at the corner of the storage bucket 3 towards the discharge port, thereby effectively utilizing all the fertilizer and avoiding waste. At the same time, it can assist the fertilizer in being discharged during sowing, preventing fertilizer from clogging the discharge port.

[0021] Working principle: During soil compaction, the tamping block 149 moves up and down, which drives the inclined plate 153 to move synchronously. The movement of the inclined plate 153 drives the moving rod 151 to move, which can prevent fertilizer from clogging inside the movable opening 13. During fertilization, the U-shaped plate 7 moves upward, which drives the hinge block 157 to move upward. The pusher plate 155 moves backward, which pushes the fertilizer accumulated at the corner of the storage bucket 3 towards the discharge port, thus effectively utilizing all fertilizer and avoiding fertilizer waste. At the same time, during sowing, it can assist the fertilizer to be discharged and prevent fertilizer from clogging the discharge port.

[0022] This invention provides an intelligent fertilization device for crop cultivation. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
