Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural planting technology, specifically to a seeder with fertilization function for agricultural planting. Background Technology
[0002] In agricultural production, sowing and fertilization are two crucial steps that directly affect crop growth and yield. Traditional methods typically require sowing and fertilization to be performed separately, which not only increases labor intensity but can also lead to uneven sowing and fertilization, negatively impacting crop growth. To improve agricultural production efficiency, reduce labor intensity, and ensure uniformity in sowing and fertilization, modern agricultural machinery is gradually developing towards multi-functionality and automation.
[0003] Most existing seeders can only perform the single function of sowing; fertilization requires separate equipment or manual operation, which not only increases costs but also reduces operational efficiency. Although some devices on the market combine sowing and fertilization functions, these devices are often complex in structure, inconvenient to operate, and difficult to achieve precise sowing and fertilization control. In addition, existing equipment is relatively weak in soil turning and leveling, failing to ensure sufficient contact between seeds and fertilizers and the soil, thus affecting crop growth.
[0004] Therefore, it is necessary to design a seeder with fertilization function for agricultural planting, so as to realize the simultaneous sowing and fertilization, and at the same time, to turn over and level the soil, thereby ensuring that seeds and fertilizers can better contact the soil, thus improving the growth effect of crops. Utility Model Content
[0005] Technical solution: A seeder with fertilization function for agricultural planting includes a base frame, with symmetrically mounted casters at the bottom of the base frame, a motor mounted on the base frame, the motor output shaft connected to the shaft for connecting the two casters on the front side of the base frame, two storage frames arranged side by side on the base frame, a spreading roller rotatably mounted at the bottom discharge channel of one storage frame, and a fertilization roller rotatably mounted at the bottom discharge channel of the other storage frame, a second transmission assembly between the spreading roller and the fertilization roller, and a first transmission assembly between the shaft for connecting the two casters on the front side of the base frame and the spreading roller or the fertilization roller.
[0006] In a preferred embodiment of the present invention, a rotating rod is rotatably provided at the front end of the base frame, and a third transmission component is provided between the rotating rod and the shaft for connecting the two moving wheels on the front side of the base frame. Arc-shaped frames are evenly spaced on the circumferential outer wall of the rotating rod, and arc-shaped frames are slidably connected to the arc-shaped frames. The arc-shaped frames are used to turn over the soil.
[0007] In a preferred embodiment of this utility model, a limiting screw is threadedly connected to the arc frame, and limiting holes are evenly spaced on the arc frame. An internal thread groove is provided on the inner wall of the limiting hole, and the limiting screw is threadedly engaged with the limiting hole.
[0008] In a preferred embodiment of this utility model, the end of the arc-shaped frame away from the arc-shaped frame is set in a triangular pyramid shape.
[0009] In a preferred embodiment of this utility model, an n-shaped rod is slidably installed on the protrusion of the base frame, and the lower end of the n-shaped rod is connected to a material-pushing frame. Conical material-pushing blocks are evenly spaced at the bottom of the material-pushing frame, and the material-pushing blocks on adjacent material-pushing frames are staggered. When the material-pushing frame moves horizontally, the material-pushing blocks flatten the protruding soil.
[0010] In a preferred embodiment of this utility model, at least one three-bladed push block is installed on the shaft for connecting the two moving wheels on the rear side of the base frame. A limit block is provided on the horizontal part of the n-shaped rod. An elastic element is provided between the limit block and the base frame. The elastic element is wound around the n-shaped rod. A wedge block is provided on the top of the feeding frame. A push rod is provided between the wedge block and the three-bladed push block. The push rod is slidably installed on the base frame. One end of the push rod is pressed against the inclined surface of the three-bladed push block, and the other end of the push rod is pressed against the inclined surface of the wedge block.
[0011] Compared with the prior art, the present invention has the following advantages: 1. When the motor drives the front moving wheel at the bottom of the base frame to work, the shaft used to connect the front moving wheel at the bottom of the base frame rotates and is driven by the first transmission component and the second transmission component, so that the sowing and fertilization processes are carried out simultaneously, which greatly improves the work efficiency. This process does not require manual intervention and has the advantage of simple operation.
[0012] 2. When the shaft used to connect the front moving wheel at the bottom of the base rotates, it drives the rotating rod to rotate through the third transmission component, so that the arc frame and arc frame rotate around the rotating rod, thereby achieving effective turning of the soil.
[0013] 3. When the moving wheels at the bottom of the base frame move, the material feeding frame is driven to move horizontally by the three-bladed pusher pressing the push rod, which flattens the soil after sowing. This ensures that the seeds are covered and avoids water loss or temperature changes caused by soil protrusion, creating good conditions for seed germination. Attached Figure Description

Detailed Implementation
[0021] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.
[0022] Example: A seeder with fertilization function for agricultural planting, such as... Figure 1 and Figure 2As shown, the device includes a base frame 1, a motor 2, a storage frame 3, a spreading roller 4, a fertilizer roller 5, a first transmission assembly 6, and a second transmission assembly 7. The base frame 1 has symmetrically mounted casters at its bottom. Notably, a push handle is located at the rear of the base frame 1, and the motor 2 is mounted at the front. The output shaft of the motor 2 is connected to a shaft connecting the two casters at the front of the base frame 1. The motor 2 drives the front wheels at the bottom of the base frame 1, thereby driving the seeder forward. Two storage frames 3 are arranged side-by-side on the top of the base frame 1, used for storing seeds and fertilizer respectively. The seeding roller 4 is rotatably mounted at the bottom discharge channel of the seed storage frame 3, and the fertilizer storage frame 3 has a similar discharge channel at its bottom. A fertilizing roller 5 is rotatably mounted on the base frame 1. A second transmission assembly 7 is provided between the spreading roller 4 and the fertilizing roller 5. A first transmission assembly 6 is provided between the shaft connecting the two moving wheels on the front side of the base frame 1 and the spreading roller 4 or the fertilizing roller 5. The fertilizing roller 5 and the spreading roller 4 rotate synchronously through the second transmission assembly 7, thereby achieving the effect of evenly spreading seeds and fertilizing. The second transmission assembly 7 includes pulleys installed at the ends of the fertilizing roller 5 and the spreading roller 4 and a flat belt between the two pulleys. The first transmission assembly 6 includes pulleys installed on the fertilizing roller 5 or the spreading roller 4, pulleys installed on the shaft connecting the two moving wheels on the front side of the base frame 1, and a flat belt between the two pulleys.
[0023] In use, the motor 2 drives the front moving wheels at the bottom of the base frame 1 to rotate, thereby driving the device to move. When the shaft connecting the two moving wheels at the front of the base frame 1 rotates, its power is transmitted through the first transmission component 6 and the second transmission component 7, thereby driving the sowing roller 4 and the fertilizer roller 5 to rotate. In this way, the seeds in the storage box 3 are evenly sown into the soil, and the fertilizer in the storage box 3 is applied to the soil, achieving the effect of simultaneous sowing and fertilization.
[0024] like Figure 1 and Figure 3 As shown, a rotating rod 8 is rotatably mounted at the front end of the base frame 1. A third transmission assembly 9 is provided between the rotating rod 8 and the shaft used to connect the two moving wheels on the front side of the base frame 1. Arc-shaped frames 10 are evenly spaced on the circumferential outer wall of the rotating rod 8. Arc-shaped frames 11 are slidably connected to the arc-shaped frames 10. The end of the arc-shaped frame 11 away from the arc-shaped frame 10 is set in a triangular pyramid shape. The arc-shaped frame 11 is mounted on the rotating rod 8 through the arc-shaped frames 10 to form a circular rake structure. When the rotating rod 8 rotates, the arc-shaped frame 11 is used to turn over the soil.
[0025] like Figure 4 As shown, a limiting screw 111 is threadedly connected to the arc frame 10, and limiting holes 110 are evenly spaced on the arc frame 11. An internal thread groove is provided on the inner wall of the limiting hole 110. The limiting screw 111 is threadedly engaged with the limiting hole 110. The depth of the arc frame 11 turning over the soil is adjusted by adjusting the length of the arc frame 11 extending out.
[0026] When the shaft connecting the two moving wheels on the front side of the base frame 1 rotates under the drive of the motor 2, the rotating rod 8 rotates along with the shaft connecting the two moving wheels on the front side of the base frame 1 through the transmission action of the third transmission component 9. This causes the arc frame 10 and the arc frame 11 to move circumferentially around the rotating rod 8. In this way, the arc frame 11 turns over the soil, thereby ensuring that the seeds and fertilizer can make better contact with the soil. By adjusting the length of the arc frame 11 and fixing the arc frame 11 with the limit screw 111 and the limit hole 110, the depth of turning over the soil can be adjusted.
[0027] like Figure 1 , Figure 5 and Figure 6 As shown, at least two n-shaped rods 15 are slidably installed on the protrusion of the base frame 1. The lower ends of the n-shaped rods 15 are connected to a material-pushing frame 14. Conical material-pushing blocks are evenly spaced at the bottom of the material-pushing frame 14. The material-pushing blocks on adjacent material-pushing frames 14 are staggered. When the material-pushing frame 14 moves horizontally, the material-pushing blocks flatten the protruding soil.
[0028] like Figure 5 and Figure 6 As shown, at least one three-bladed push block 12 is installed on the shaft connecting the two moving wheels on the rear side of the base frame 1. A limit block 151 is provided on the horizontal part of the n-shaped rod 15. An elastic element 152 is provided between the limit block 151 and the base frame 1. The elastic element 152 is wound around the n-shaped rod 15. When the n-shaped rod 15 is subjected to force and moves horizontally, it compresses the elastic element 15. When the force driving the n-shaped rod 15 to move horizontally is released, the elastic element 152 drives the n-shaped rod 15 to return to its original position. The elastic element 15 is normally... Figure 6 As shown, the elastic element 15 is a compression spring. A wedge block 16 is provided on the top of the feeding frame 14. The wedge block 16 is adapted to the three-blade push block 12. A push rod 13 is provided between the wedge block 16 and the three-blade push block 12. The push rod 13 is slidably mounted on the base frame 1. One end of the push rod 13 is pressed and engaged with the inclined surface of the three-blade push block 12, and the other end of the push rod 13 is pressed and engaged with the inclined surface of the wedge block 16. When the three-blade push block 12 rotates counterclockwise, the inclined surface of the three-blade push block 12 is pressed and engaged with the push rod 13, thereby driving the push rod 13 to move towards the wedge block 16 and press and engage with the inclined surface of the wedge block 16, thereby pushing the feeding frame 14 to move horizontally away from the inclined surface of the wedge block 16.
[0029] When the movable wheels on the base frame 1 rotate, the shaft connecting the two movable wheels on the rear side of the base frame 1 rotates clockwise with the movable wheels. When the three-bladed push block 12 moves accordingly, its inclined surface presses against the push rod 13, thereby driving the push rod 13 to press against the inclined surface of the wedge block 16. After the inclined surface of the wedge block 16 is compressed, it drives the material feeding frame 14 to move away from the inclined surface of the wedge block 16. The material feeding block on the material feeding frame 14 flattens the protruding soil, and the n-shaped rod 15 moves horizontally accordingly. The elastic element 152 is compressed and deformed. When the inclined surface of the three-bladed push block 12 moves away from the push rod 13, the material feeding frame 14 and the n-shaped rod 15 return to their original positions under the action of the elastic element 152. The soil is flattened by the reciprocating horizontal movement of the material feeding frame 14, thereby covering the seeds and fertilizers sown in the soil.
