Description

A multi-functional fertilizer spreading and ridging seeder Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a multifunctional fertilizing, ridging and sowing machine. Background Technology

[0002] In agricultural production, fertilization, ridging, and sowing are crucial operational steps that significantly impact crop growth and yield. Traditional fertilization, ridging, and sowing operations typically require the use of different agricultural machinery, which not only increases operating costs but also reduces efficiency. Furthermore, the lack of seamless coordination between different machines can lead to inconsistent quality in fertilization, ridging, and sowing, negatively affecting the crop's growing environment.

[0003] With the development of agricultural mechanization, some multi-functional agricultural implements have emerged on the market, attempting to integrate fertilization, ridging, and sowing into a single machine. However, existing multi-functional agricultural implements still have many shortcomings in practical use. For example, the ridge spacing adjustment of some machines is not flexible enough to adapt to the planting needs of different crops; the synchronization of fertilization and sowing mechanisms is poor, resulting in uneven application of fertilizer and seeds; and the complex structure of the equipment leads to high maintenance and repair costs. These problems limit the widespread application of multi-functional agricultural implements in agricultural production.

[0004] To address the aforementioned problems, this utility model document proposes a multi-functional fertilizer application, ridging, and seeding machine. Summary of the Invention

[0005] The purpose of this utility model is to solve the shortcomings of existing agricultural machinery, such as limited functionality, inconvenient adjustment of ridge spacing during operation, asynchronous fertilization and sowing, complex structure, and high maintenance costs. Therefore, a multi-functional fertilization, ridging, and sowing machine is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-functional fertilizer spreading and ridging seeder includes:

[0008] The support frame consists of two support rods and two connecting plates. The two support rods are located between the two connecting plates, and their two ends are fixedly connected to the adjacent connecting plates to form a rectangular frame. The tops of the two support rods are fixedly mounted with a fixing frame, and the two fixing frames are fixedly mounted with a connecting frame.

[0009] Three sets of moving components are all located inside the support frame. The middle moving component is fixedly connected to the support frame, while the other two sets of moving components are slidably installed inside the support frame. Each set of moving components includes a soil turning shovel, a fertilizer application mechanism, two soil covering plates, and a seeding mechanism.

[0010] When the equipment moves forward, the soil-turning shovel is used to open trenches, the fertilization mechanism is used to apply fertilizer in the trenches, the soil-covering board is used to cover the soil to form ridges, and the sowing mechanism is used to sow seeds on the ridges.

[0011] In one possible design, a double-threaded screw is rotatably passed through the bottom of the connecting frame, and the two ends of the double-threaded screw rotatably pass through adjacent connecting plates respectively; a fixing block is fixedly installed on the top of the movable mounting rod of the two movable components, the fixing block is threadedly connected to the double-threaded screw and located on the opposite thread section of the double-threaded screw; the distance between the two movable components can be adjusted by rotating the double-threaded screw.

[0012] In one possible design, the movable assembly further includes a movable mounting rod and two sliding collars, the sliding collars being fixedly installed at both ends of the movable mounting rod and slidably fitted onto the outer wall of the support rod; two mounting frames are fixedly embedded inside the movable mounting rod, respectively for installing the fertilization mechanism and the sowing mechanism.

[0013] In one possible design, a fixed rod is fixedly installed at the bottom of one of the sliding collars, and the soil-turning shovel is fixed to the outer wall of the fixed rod by a bracket; L-shaped brackets are fixedly installed on both sides of the movable mounting rod, and the two soil-covering plates are respectively fixed to the L-shaped brackets and are inclined relative to the forward direction of the equipment, gradually moving closer to the end away from the soil-turning shovel.

[0014] In one possible design, the fertilizer application mechanism includes a first storage cylinder and a first discharge pipe, the first discharge pipe being fixed to the bottom of the first storage cylinder; the first discharge pipe is provided with a limiting frame, a connecting rod, a piston block, a return spring, a rotating shaft, and a cam inside; the piston block cooperates with the discharge port at the bottom of the first storage cylinder; the cam intermittently abuts against the connecting rod when rotating, causing the piston block to intermittently open the discharge port.

[0015] In one possible design, the seeding mechanism includes a second storage cylinder and a second discharge pipe, the second discharge pipe being fixed to the bottom of the second storage cylinder; a seeding wheel is rotatably mounted at the bottom end of the second discharge pipe, and the outer circumference of the seeding wheel is evenly provided with multiple discharge grooves for quantitatively discharging seeds.

[0016] In one possible design, a first synchronous wheel is fixed to one end of the rotating shaft, a double-groove synchronous wheel is rotatably mounted on one side of the second discharge pipe, and a second synchronous wheel is fixed to one end of the sowing wheel shaft; the first synchronous wheel is connected to one groove of the double-groove synchronous wheel by a synchronous belt, and the second synchronous wheel is connected to the other groove of the double-groove synchronous wheel by a synchronous belt, thereby achieving synchronization of sowing and fertilization.

[0017] In one possible design, two mounting brackets are fixedly installed on the side of the fixed frame near the soil turning shovel, which are used to connect external drive equipment.

[0018] In one possible design, a return spring is fitted on the outer wall of the connecting rod. The top end of the return spring is fixedly connected to the bottom of the limiting frame via a spring seat, and the bottom end is fixedly connected to the bottom end of the connecting rod via a spring seat.

[0019] In this application, during use, the equipment is installed and connected to an external drive device (such as a tractor or rotary tiller) via a mounting bracket.

[0020] Before the equipment starts working, the operator can rotate and adjust the double-threaded screw according to the required ridge spacing. When the double-threaded screw rotates, its two ends can drive the two fixed blocks to move towards or away from each other, which in turn can drive the sliding collars of the moving components on both sides to slide along the support rod, thereby changing the distance between the three moving components, thus adjusting the ridge width and the sowing row spacing.

[0021] As the equipment moves forward, the soil-turning shovel cuts into the soil to form trenches, and the excavated soil accumulates on both sides of the trenches. In the fertilization mechanism located behind the shovel, fertilizer from the first storage cylinder falls through the first discharge pipe, ensuring that the fertilizer is evenly applied to the prepared trenches. When the fertilization mechanism is working, the rotating shaft drives the cam to rotate, which intermittently engages the connecting rod to rise, causing the piston block to disengage from the discharge port at the bottom of the first storage cylinder. At this time, the fertilizer in the first storage cylinder can enter the first discharge pipe through the gap and be discharged. When the cam is not engaged, the return spring pushes the connecting rod to return to its original position, at which point the piston block closes the discharge port, thus achieving intermittent and quantitative discharge of fertilizer into the trench.

[0022] The two soil-covering slabs are arranged at an angle. As the equipment moves forward, the soil pushed out by the soil-turning shovel is backfilled into the center of the trench to form a ridge. At this time, the applied fertilizer can be buried in the ridge.

[0023] As the equipment moves forward, the seeds in the second storage cylinder of the sowing mechanism fall to the bottom of the second discharge pipe. As the sowing wheel rolls in contact with the ground, the discharge groove on its circumference can collect the seeds in sequence and carry them into the soil to complete the sowing.

[0024] When the seeding reel rotates, the first synchronous wheel is driven to rotate via the second synchronous wheel, the double-groove synchronous wheel, and the synchronous belt. This, in turn, drives the rotating shaft of the fertilization mechanism to rotate synchronously, ensuring the synchronized operation and coordinated coordination of sowing and fertilization. After sowing, the operator should follow behind the equipment to check the sowing status and cover any seeds that have not yet entered the soil with soil.

[0025] Beneficial effects: The multifunctional fertilizing and ridging seeder described in this utility model can flexibly adjust the ridge spacing according to different crop planting needs by setting adjustable moving components; the operator only needs to rotate the double threaded screw to drive the moving components on both sides to slide along the support rod, thereby changing the distance between the three moving components and realizing precise adjustment of the ridge width and planting row spacing; this design greatly improves the applicability of the equipment and meets the planting requirements of different crops;

[0026] In this utility model, the multifunctional fertilizing and ridging seeder allows the fertilizing mechanism and the sowing mechanism to operate synchronously and coordinately. While the sowing wheel is rolling and sowing, it can drive the rotating shaft of the fertilizing mechanism to rotate via a synchronous belt drive system, ensuring that fertilizer and seeds are evenly applied according to a predetermined ratio and rhythm. This synchronous design not only improves the quality of fertilization and sowing but also reduces fertilizer waste and uneven seed distribution caused by improper operation.

[0027] In this utility model, the multifunctional fertilizer-applying and ridging seeder adopts an intermittent quantitative dispensing design for its fertilizer application mechanism. Through the cooperation of a cam, connecting rod, and return spring, the piston block intermittently closes and opens the discharge port at the bottom of the first storage cylinder, thereby ensuring that the fertilizer can be applied evenly and quantitatively into the prepared furrows. This design avoids over- or under-application of fertilizer, improves fertilizer utilization, and also helps to improve the soil environment and promote crop growth.

[0028] In this utility model, the multifunctional fertilizing and ridging seeder adopts a quantitative sowing method using a sowing wheel. Multiple discharge troughs are evenly opened on the circumferential surface of the sowing wheel. As the sowing wheel rolls, the discharge troughs sequentially collect the seeds and carry them into the soil to complete the sowing. This design ensures the uniform distribution of seeds and improves the accuracy and efficiency of sowing.

[0029] In this utility model, the multi-functional fertilizing ridging and seeding machine has a simple overall structure and is easy to maintain. The support frame, moving components, fertilizing mechanism and seeding mechanism are all modularly designed, which facilitates disassembly and replacement. At the same time, the operation of the equipment is relatively simple, reducing the technical requirements for operators. These features make the equipment more practical and economical in agricultural production.

[0030] In this invention, the multi-functional fertilizing and ridging seeder uses a double-threaded screw to adjust the spacing of the moving components, enabling quick and convenient adjustment of the ridge spacing; synchronous belt drive ensures coordinated sowing and fertilization operations, guaranteeing the seed-fertilizer ratio; cam linkage mechanism controls intermittent quantitative fertilizer output, and the seed wheel discharge trough ensures uniform seed distribution, which helps to ensure relatively stable sowing quality; the modular structure of the equipment allows for convenient maintenance, improving overall operating efficiency and equipment practicality.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0039] In one embodiment: Referring to Figures 1-6, a seeder includes: a support frame 1, a moving component, and a mounting bracket 5 for connecting an external drive device.

[0040] In this embodiment, the support frame 1 consists of two support rods 2 and two connecting plates 3. The two support rods 2 are located between the two connecting plates 3, and their two ends are respectively fixedly connected to one side of the adjacent connecting plate 3, thereby forming a rectangular support frame. A fixing frame 4 is fixedly installed on the top of each of the two support rods 2, and the same connecting frame 8 is fixedly installed between the two fixing frames 4.

[0041] In this embodiment, there are three sets of movable components, all located within the support frame 1. The middle movable component is located at the center of the support frame 1 and is fixedly connected to the support frame 1, while the other two sets of movable components can slide within the support frame 1.

[0042] Further, in this embodiment, the movable component includes a movable mounting rod 6, two sliding collars 7, a soil-turning shovel 13, a fertilization mechanism, two soil-covering plates 15, and a sowing mechanism. The two sliding collars 7 are respectively fixedly installed at both ends of the movable mounting rod 6, and both are slidably sleeved on the outer wall of the adjacent support rod 2. The two sliding collars 7 of the middle movable component are both fixedly connected to the outer wall of the adjacent support frame 1, and the bottom of the connecting frame 8 is fixedly connected to the top of the movable mounting rod 6 of the middle movable component via a bracket. A fixing block 10 is fixedly installed at the top of the movable mounting rod 6 of the two movable components. A double-threaded screw 9 is rotatably passed through the bottom of the connecting frame 8 via a bracket. The two ends of the double-threaded screw 9 rotatably pass through the adjacent connecting plates 3. The two fixing blocks 10 are threadedly connected to the outer wall of the double-threaded screw 9, and are respectively located on two opposite threaded segments of the outer wall of the double-threaded screw 9. By rotating the double-threaded screw 9, the movement and adjustment of the two movable components can be realized.

[0043] In this embodiment, two mounting frames 11 are fixedly embedded inside the movable mounting rod 6, respectively used for installing the fertilization mechanism and the sowing mechanism. A fixed rod 12 is fixedly installed at the bottom of one of the sliding collars 7. A soil-turning shovel 13 is fixedly installed on the outer wall of the fixed rod 12 via a bracket, located near the bottom of the corresponding fixed rod 12, for trenching and turning the soil. L-shaped brackets 14 are fixedly installed on both sides of the movable mounting rod 6, with each L-shaped bracket 14 located between the two mounting frames 11. Two soil-covering plates 15 are fixedly connected to the adjacent sides of the two L-shaped brackets 14. The two soil-covering plates 15 are inclined relative to the direction of equipment movement, and the ends away from the soil-turning shovel 13 gradually move closer together, so that the soil turned out by the soil-turning shovel 13 can be filled back into the trenches, forming furrows.

[0044] In this embodiment, the fertilization mechanism includes a first storage cylinder 16 and a first discharge pipe 17. The first discharge pipe 17 is fixedly installed at the bottom of the first storage cylinder 16 and communicates with the first storage cylinder 16, and is also fixedly installed inside the corresponding mounting frame 11. The fertilization mechanism is located between adjacent soil turning shovels 13 and two soil covering plates 15. A limiting frame 22 is fixedly installed inside the first discharge pipe 17. A connecting rod 21 is slidably installed inside the limiting frame 22. The top end of the connecting rod 21 extends into the first storage cylinder 16 and is fixedly installed with a piston block 20. The piston block 20 cooperates with the bottom discharge port of the first storage cylinder 16 to complete the closing and opening of the bottom discharge port of the first storage cylinder 16. A rotating shaft 25 rotatably passes through the inside of the first discharge pipe 17. A cam 24 is fixedly sleeved on the outer wall of the rotating shaft 25. The cam 24 is located inside the first discharge pipe 17 and abuts against the bottom end of the connecting rod 21. A return spring 23 is fitted on the outer wall of the connecting rod 21. The top end of the return spring 23 is fixedly connected to the bottom of the limiting frame 22 through a spring seat, and the bottom end of the return spring 23 is fixedly connected to the bottom end of the connecting rod 21 through a spring seat. When the cam 24 rotates, it can intermittently abut against the connecting rod 21 to rise, thereby completing the intermittent separation between the piston block 20 and the discharge port at the bottom end of the first storage cylinder 16, realizing the intermittent discharge of fertilizer from the first storage cylinder 16.

[0045] In this embodiment, the sowing mechanism includes a second storage cylinder 18 and a second discharge pipe 19. The second discharge pipe 19 is fixedly installed at the bottom of the second storage cylinder 18 and communicates with it, and is also fixedly installed inside the corresponding mounting frame 11. A sowing wheel 26 is rotatably mounted on the bottom end of the second discharge pipe 19 via a bracket. The outer circumferential wall of the sowing wheel 26 is slidably and sealingly connected to the bottom end of the second discharge pipe 19. Multiple discharge grooves 27 are evenly distributed on the outer circumferential wall of the sowing wheel 26, and these grooves 27 cooperate with the bottom end of the second discharge pipe 19 to quantitatively discharge seeds from the second storage cylinder 18. The sowing wheel 26 is in contact with the soil. When the equipment moves, the sowing wheel 26 can rotate synchronously, cooperating with the multiple discharge grooves 27 to complete uniform sowing.

[0046] In this embodiment, a first synchronous pulley 28 is fixedly installed at one end of the rotating shaft 25, and the first synchronous pulley 28 is located outside the first discharge pipe 17. A double-groove synchronous pulley 29 is rotatably installed on one side of the second discharge pipe 19 via a rotating shaft, and the first synchronous pulley 28 and the double-groove synchronous pulley 29 are connected by a synchronous belt drive. A second synchronous pulley 30 is fixedly installed at one end of the rotating shaft of the sowing wheel 26, and the second synchronous pulley 30 is connected to the other drive groove of the double-groove synchronous pulley 29 by a synchronous belt drive. In this way, while the sowing wheel 26 continuously rotates to sow seeds, the first discharge pipe 17 can be synchronously fertilized, ensuring that fertilization and sowing are carried out simultaneously.

[0047] This application can be used in the field of agricultural planting technology, or in other fields applicable to this application.

[0048] In another embodiment: Referring to Figure 1, a multi-functional fertilizer-applying, ridging, and seeding machine is applied to the field of agricultural planting technology;

[0049] In this embodiment, two mounting brackets 5 are fixedly installed on one side of the fixed frame 4 near the multiple soil turning shovels 13. These two mounting brackets 5 cooperate with each other to connect the support frame 1 to the external driving equipment so as to realize the installation and movement of the equipment.

[0050] The working principle and usage process of this technical solution are as follows: When in use, the equipment is installed and connected to external drive equipment (such as tractors or rotary tillers) through the mounting frame 5.

[0051] Before the equipment is put into operation, the operator can rotate the double threaded screw 9 to adjust the ridge spacing as needed. When the double threaded screw 9 rotates, its two ends can drive the two fixed blocks 10 to move towards or away from each other, which in turn can drive the sliding collars 7 of the moving components on both sides to slide along the support rod 2, thereby changing the distance between the three moving components, thus adjusting the ridge width and the sowing row spacing.

[0052] As the equipment is carried forward, the soil-turning shovel 13 cuts into the soil to form trenches, and the excavated soil accumulates on both sides of the trenches. In the fertilization mechanism located behind the soil-turning shovel 13, fertilizer from the first storage cylinder 16 falls through the first discharge pipe 17, ensuring that the fertilizer is evenly applied to the prepared trenches. When the fertilization mechanism is working, the rotating shaft 25 drives the cam 24 to rotate, which intermittently abuts against the connecting rod 21 to rise, thereby causing the piston block 20 to disengage from the discharge port at the bottom of the first storage cylinder 16. At this time, the fertilizer in the first storage cylinder 16 can enter the first discharge pipe 17 through the gap and be discharged. When the cam 24 is not abutting, the return spring 23 can push the connecting rod 21 to return to its original position, at which point the piston block 20 closes the discharge port, thus achieving intermittent and quantitative discharge of fertilizer into the trench.

[0053] The two soil-covering plates 15 are arranged at an angle. As the equipment moves forward, the soil pushed out by the soil-turning shovel 13 can be backfilled into the center of the trench to form a ridge. At this time, the applied fertilizer can be buried in the ridge.

[0054] As the equipment moves forward, the seeds in the second storage cylinder 18 of the sowing mechanism fall into the bottom of the second discharge pipe 19. As the sowing wheel 26 rolls in contact with the ground, the discharge groove 27 on its circumference surface can sequentially collect the seeds and carry them into the soil to complete the sowing.

[0055] When the seeding reel 26 rotates, it can drive the first synchronous pulley 28 to rotate via the second synchronous pulley 30, the double-groove synchronous pulley 29, and the synchronous belt. This, in turn, drives the rotating shaft 25 of the fertilization mechanism to rotate synchronously, ensuring the synchronous operation and coordinated coordination of sowing and fertilization. After sowing is completed, the operator should follow behind the equipment to check the sowing status and cover any seeds that have not yet entered the soil with soil.

[0056] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
