Its key components include a motor, a lead screw, a nut, a guide rail, a slider, etc. Its core working principle is that the motor drives the lead screw to rotate, and the nut on the lead screw moves along the axial direction of the lead screw during the rotation process, thereby converting the rotational motion into linear motion. The nut and the slider are connected, and the slider slides along the guide rail to push the load to achieve linear motion. The seed removal member 4 is provided with a release member 5 that releases the grass seeds in the seed removal member 4 and leaves them in the soil;

[0038] The seed storage member 1 includes a seed storage barrel 11 and a closing plate 12 fixedly connected to the side end of the seed storage barrel 11, and a seed taking box 13 fixedly connected to the bottom end of the seed storage barrel 11. The cross-sections of the seed storage barrel 11 and the closing plate 12 are both arched and inclined, so that the connection between the straight side and the arc side of the arch is the lowest point. The closing plate 12 is provided with two groups symmetrically distributed on both sides of the seed storage barrel 11 to form a cavity. The bottom end of the seed taking box 13 is respectively penetrated by a movable groove 14 and a movable groove 2 15. The movable groove 2 15 is provided with two sides, symmetrically distributed on both sides of the movable groove 14, and is connected to the movable groove 14.

The linkage groove 17, the limiting groove 16 and the driving groove 18 are N-shaped. There are two groups of linkage grooves 17, the limiting grooves 16 and the driving grooves 18, which are symmetrically distributed on the two groups of closed plates 12. The widths of the limiting grooves 16 and the linkage grooves 17 are the same as the width of the movable groove 2 15, and the limiting grooves 16 and the linkage grooves 17 are connected to the movable groove 2 15.

[0039] Reference Figures 8 to 14The seed-taking piece 4 includes an inserting plate 41 that passes through the bottom end of the movable groove 14 and is slidably inserted with the movable groove 14. The width of the inserting plate 41 is the same as that of the movable groove 14. The cross-section of the inserting plate 41 is a parallelogram, and its top and bottom ends are two sets of parallel inclined surfaces. One end of the inserting plate 41 is in contact with the straight surface of the arched seed storage cylinder 11, and due to the inclined state of the seed storage cylinder 11, the top inclined surface of the inserting plate 41 can guide the grass seeds inside the seed storage cylinder 11 to the side of the arc surface of the seed storage cylinder 11, and the inclined surface at the bottom of the inserting plate 41 can be obliquely inserted into the soil in its inclined state. A fixed groove 42 is provided at one end of the inserting plate 41, and the fixed groove 42 is composed of a plurality of groups of semi-cylindrical grooves and hemispherical grooves distributed in an alternating manner. The inner side of the hemispherical groove has an inverted bevel. Each group of hemispherical grooves in the fixed groove 42 is A group of temporary storage grooves 43 are provided at the bottom end of the groove, and a seeding spoon 44 is provided in the fixed groove 42. The seeding spoon 44 is composed of multiple groups of semi-cylindrical connecting columns and hemispherical and internally recessed material taking blocks that are staggered. The total length of the multiple groups of semi-cylindrical connecting columns and hemispherical and internally recessed material taking blocks is the same as that of the insert plate 41, and the end faces of the two groups of semi-cylindrical connecting columns at both ends are fixedly connected to a group of cylindrical connecting columns. When the seeding spoon 44 is in the fixed groove 42, the straight surfaces of the semi-cylindrical connecting columns and the hemispherical and internally recessed material taking blocks are flush with one side of the insert plate 41. One end of the cylindrical connecting column in the seeding spoon 44 passes through the limiting groove 16 and the linkage groove 17, and is rotatably connected to the linkage rod 45 in the linkage groove 17. The linkage rod 45 is slidably plugged into the bottom end of the linkage groove 17 , one side of the connecting rod 45 is fixedly connected to the driving rod 46, one end of the driving rod 46 passes through the driving groove 18 and is slidably plugged into the driving groove 18, the movable end of the linear drive 3 is fixedly connected to one end of the driving rod 46, and each group of cylindrical connecting columns in the seed taking spoon 44 is fixedly connected to a group of gears 47 on the outside, and the gears 47 are slidably plugged into the bottom end of the limit groove 16. A group of mounting grooves 48 are opened on the inner wall of each group of moving grooves 15, and a group of racks 49 are fixedly connected to the inner wall of each group of mounting grooves 48. The gears 47 are adapted to the racks 49, and the number of teeth of the racks 49 enables the gears 47 to rotate 360 degrees. The inner wall of the moving groove 14 in the seed taking box 13 is provided with a flip groove 410 that rotates the seed taking spoon 44 when the gear 47 is engaged with the rack 49. The flip grooves 410 are multiple groups of semi-rotating The capsule-shaped grooves and multiple groups of straight grooves are staggered to form a semi-capsule-shaped groove inner diameter in the flip groove 410 is the same as the outer diameter of the hemispherical material block in the seed taking spoon 44, and the depth of the straight groove in the flip groove 410 is the same as the diameter of the semi-cylindrical connecting column in the seed taking spoon 44. The height of the flip groove 410 can make the seed taking spoon 44 rotate therein and return to a state flush with one side of the insert plate 41, completing a 360-degree rotation, so that the grass seeds in the hemispherical material block in the seed taking spoon 44 fall into the temporary storage groove 43. Under the drive of the linear drive 3, the driving rod 46 slides along the driving groove 18, and drives the seed taking spoon 44 to move in the combined track of the connecting groove 17 and the limit groove 16 through the connecting rod 45. At the same time, the insert plate 41 slides downward along the moving groove 14. Since the seed storage cylinder 11 is tilted,The grass seeds slide along the arc surface, and the top inclined surface of the insert plate 41 guides the grass seeds toward one side of the arc surface of the seed storage cylinder 11, so that the grass seeds enter the hemispherical material block groove of the seed scoop 44. When the seed scoop 44 moves out of the seed storage cylinder 11, the excess grass seeds are scraped off by the inner wall of the movable groove 14. As the seed scoop 44 continues to move, the cylindrical connecting columns at both ends drive the gear 47 to enter the mounting groove 48 of the movable groove 2 15. After meshing with the rack 49, the gear 47 rotates along the rack 49, driving the seed scoop 44 to rotate 360 degrees in the flip groove 410. The grass seeds fall into the temporary storage groove 43 at the bottom of the fixed groove 42 due to gravity. The seed scoop 44 is restored to be flush with the side of the insert plate 41, which is convenient for subsequent insertion into the soil.

[0040] The above scheme is adopted: through the engagement of the gear 47 and the rack 49 and the cooperation with the flip groove 410, the grass seeds are automatically and accurately transferred, avoiding errors and efficiency losses caused by manual intervention. The inclined surface adaptation design of the insert plate 41 and the seed storage cylinder 11 can not only efficiently guide the grass seeds into the seed scoop 44, but also ensure that the insert plate 41 is smoothly inserted into the soil. The functional integration is high. The scraping mechanism of the seed scoop 44 and the inner wall of the movable groove 14 can effectively control the amount of seeds taken and reduce grass seed waste. The design of the seed scoop 44 being flush with the side of the insert plate 41 after flipping, and the closed structure of the temporary storage groove 43 prevent the grass seeds from scattering during transportation and sowing, ensure the uniformity and stability of sowing, and provide reliable guarantee for the efficiency and quality of forage planting.

[0041] Reference Figure 5 as well as Figures 12 to 14The releasing member 5 includes a sowing groove 51 opened on one side of the plug plate 41, the sowing groove 51 passes through the bottom end of the plug plate 41, the sowing groove 51 is L-shaped, and the width of the sowing groove 51 is three times the width of the temporary storage groove 43. The top of the sowing groove 51 is connected to the bottom end of the temporary storage groove 43, and the inner side of the sowing groove 51 is flush with the inner side of the temporary storage groove 43. The bottom end of each group of temporary storage grooves 43 is connected to a group of sowing grooves 51, and the side end of the temporary groove 43 is fixedly connected to a baffle 52, and the baffle 52 is flush with one side of the plug plate 41. One end of the baffle 52 extends into the temporary storage groove 43 and is at half the height of the temporary groove 43. The baffle 52 is L-shaped, and the temporary groove 43 and the sowing groove 51 become a relatively closed cavity through the baffle 52. A blocking block 53 is slidably inserted in the temporary groove 43, and the blocking block 53 is The width of the L-shape is twice the width of the temporary storage groove 43, and it is composed of a group of blocks and a group of inserting blocks. The block and the inserting block have the same width. The height of the L-shaped blocking block 53 is lower than the sowing groove 51. The cross section of the blocking block is triangular, and the inclined surface is facing downward. In the blocking state, the L-shaped blocking block 53 blocks the L-shaped sowing groove 51, so that the temporary storage groove 43 is disconnected from the sowing groove 51. The grass seeds falling into the temporary storage groove 43 fall on the top of the blocking block 53 and are restricted in the cavity formed by the baffle 52 and the temporary storage groove 43 to prevent the grass seeds from falling due to external force after one side of the inserting plate 41 moves out of the moving groove 14. The bottom end of the inserting plate 41 presents a shallow groove state. Each group of temporary storage grooves 43 is provided with a group of blocking blocks 53. Multiple groups of blocking blocks 53 are fixedly connected to multiple groups of connecting plates 54, and the connecting plates 54 are embedded in the sowing groove. The inner wall of the groove 51 passes through the plug plate 41 and is slidably plugged with the plug plate 41. One end of the plug plate 41 is fixedly connected to a movable plate 56. The cross section of the movable plate 56 is triangular, with the inclined surface facing downward. The other end of the plug plate 41 is fixedly connected to a reset plate 55. The width of the reset plate 55 is greater than that of the movable groove 15. The cross section of the reset plate 55 is triangular, with the inclined surface facing upward. An activation groove 57 is provided at the bottom of the plug plate 41. The activation groove 57 is L-shaped and passes through the bottom of the plug plate 41. The movable plate 56 is arranged in the activation groove 57 and is slidably plugged with the activation groove 57. The depth of the activation groove 57 is twice the length of the movable plate 56. As the plug plate 41 is inserted into the soil, the soil will enter the activation groove 57 and abut against the inclined surface of the movable plate 56. As the amount of soil entering the soil increases, the blocking block 53 and the connecting plate 54 are pushed to move , so that the reset plate 55 on the other side moves out of the plug plate 41, and during the movement of the blocking block 53, it moves out from under the temporary storage groove 43, so that the grass seeds facing the top of the blocking block 53 in the temporary storage groove 43 enter the soil through the sowing groove 51, completing the sowing. When resetting, the plug plate 41 moves up, so that the inclined surface of the reset plate 55 abuts against the edge of the bottom end of the seed box 13, and under the abutment action, the blocking block 53 and the connecting plate 54 are reset. When the bottom inclined surface of the plug plate 41 is inserted into the soil, soil particles enter the inside of the plug plate 41 through the L-shaped activation groove 57 and abut against the inclined surface of the moving plate 56. As the plug plate 41 is inserted into the soil deeper, the thrust of the soil on the moving plate 56 gradually increases, pushing the blocking block 53 and the connecting plate 54 connected thereto to slide along the sowing groove 51. Since the blocking block 53 is an L-shaped structure,During the movement, it will move out from under the temporary storage groove 43, connecting the temporary storage groove 43 with the L-shaped sowing groove 51. The grass seeds originally blocked in the temporary storage groove 43 by the blocking block 53 will fall through the sowing groove 51 into the soil pit where the insert plate 41 is inserted, completing the sowing action. When the insert plate 41 moves up and resets, the inclined surface of the reset plate 55 contacts the edge of the bottom end of the seed box 13. The thrust of the edge on the reset plate 55 is transmitted to the blocking block 53 through the connecting plate 54, causing it to slide in the opposite direction along the sowing groove 51 and re-block the bottom of the temporary storage groove 43. The movable plate 56 is also reset synchronously in the activation groove 57. The triangular insert of the blocking block 53 is inserted into the connection between the temporary storage groove 43 and the sowing groove 51 to prevent the grass seeds from falling.

[0042] The above scheme is adopted: the reaction force of the soil on the plug plate 41 is used by the release member 5 to trigger the release of grass seeds, without the need for an additional power device, reducing energy consumption and having a simple and reliable structure. The L-shaped blocking block 53 cooperates with the sowing groove 51 to form a closed temporary storage space, which effectively prevents the grass seeds from being scattered or lost during transportation and waiting for sowing, ensuring the accurate delivery of grass seeds. The automatic reset of the blocking block 53 is achieved through the mechanical linkage between the reset plate 55 and the edge of the seed box 13, ensuring that the device can be recycled, improving the continuity of sowing, creating good conditions for forage growth, and helping to improve the survival rate and uniformity of forage planting.

[0043] The working principle of the uniform seeding device for forage planting provided by the present invention is as follows:

[0044] When the inserting plate 41 slides downward along the moving groove 14 under the drive of the linear drive 3, the seed storage cylinder 11 causes the grass seeds inside to slide along the arched arc surface due to its inclined setting. The inclined surface at the top of the inserting plate 41 guides the grass seeds toward one side of the arc surface of the seed storage cylinder 11, so that some grass seeds enter the groove in the material taking block in the seed taking spoon 44. At this time, the driving rod 46 slides along the driving groove 18 under the drive of the movable end of the linear drive 3, and the seed taking spoon 44 moves in the combined track of the linkage groove 17 and the limit groove 16 through the connecting rod 45. Moreover, since the seed taking spoon 44 is set in the fixed groove 42, the inserting plate 41 slides synchronously under the abutment action. When the seeding spoon 44 moves out of the seed storage cylinder 11, the excess grass seeds are scraped off under the action of the material block in the seeding spoon 44 and the inner wall of the moving groove 14. Only the grass seeds in the seeding spoon 44 are taken out and enter the moving groove 14 in the seeding box 13. Since the inserting plate 41 is the same as the moving groove 14, the grass seeds in the seeding spoon 44 are restricted between the seeding spoon 44 and the inner wall of the moving groove 14. As the movement proceeds, when the cylindrical connecting columns at both ends of the seeding spoon 44 drive the gear 47 to enter the mounting groove 48 of the moving groove 2 15, the gear 47 and the rack 49 begin to mesh, and the seeding spoon 44 enters the flip groove 410. As the insert plate 41 moves downward, the gear 47 rotates along the rack 49, driving the seeding spoon 44 to rotate 360 degrees, so that the grass seeds fall into the temporary storage groove 43 at the bottom of the fixed groove 42 due to gravity. At this time, the straight surface of the seeding spoon 44 is flush with the side of the insert plate 41, ensuring that the insert plate 41 can be smoothly inserted into the soil. When the inclined surface at the bottom of the insert plate 41 is inserted into the soil, soil particles enter the inside of the insert plate 41 through the activation groove 57 and abut against the inclined surface of the movable plate 56. As the insertion depth increases, the thrust of the soil on the movable plate 56 increases, pushing the blocking block 53 to slide along the sowing groove 51. The L-shaped structure of the blocking block 53 allows it to be removed from the temporary storage groove 43. The movable plate 56 is then retracted from the activating groove 57, and the triangular insert of the blocking block 53 is inserted into the connection between the temporary storage groove 43 and the sowing groove 51, thereby preventing the grass seeds from falling.The seed taking part 4 realizes the precise quantitative extraction and transfer of grass seeds. The cooperation of the parallelogram inserting plate 41 and the inclined seed storage cylinder 11 allows the grass seeds to slide naturally to the seed taking spoon 44. The excess grass seeds are scraped off by the inner wall of the movable groove to ensure the consistency of the single seed taking amount. The gear 47 and the rack 49 drive the seed taking spoon 44 to turn 360 degrees and pour the grass seeds accurately into the temporary storage groove 43 to avoid spillage and waste. The structural design of the seed taking spoon 44 and the side of the inserting plate 41 ensures that the inserting plate 41 is smoothly inserted into the soil and prevents the grass seeds from being lost during transportation, which significantly improves the sowing efficiency and uniformity. The release member 5 enables timely and precise seed placement. The soil's thrust on the movable plate 56 triggers the movement of the blocking block 53, connecting the temporary storage trough 43 with the sowing trough 51. The seeds then fall into the soil. No additional power source is required, resulting in a simple and reliable structure. The closed cavity formed by the L-shaped blocking block 53 and the baffle 52 effectively prevents seeds from accidentally falling out during insertion or lifting. A reset mechanism ensures the device's reusability. The triangular insert further seals the sowing channel to prevent seed leakage. This insert-and-sow design adapts to varying soil conditions and ensures consistent sowing depth and density.

[0046] Beneficial effects:

[0047] The seed taking part 4 realizes the precise quantitative extraction and transfer of grass seeds. The cooperation of the parallelogram inserting plate 41 and the inclined seed storage cylinder 11 allows the grass seeds to slide naturally to the seed taking scoop 44. The excess grass seeds are scraped off by the inner wall of the movable groove to ensure the consistency of the single seed taking amount. The gear 47 and the rack 49 drive the seed taking scoop 44 to turn 360 degrees, and the grass seeds are accurately poured into the temporary storage groove 43 to avoid spillage and waste. The structural design of the seed taking scoop 44 and the side of the inserting plate 41 is flush, which not only ensures that the inserting plate is smoothly inserted into the soil, but also prevents the grass seeds from being lost during transportation. When the inserting plate 41 is reset to extract the soil, the soil automatically covers the grass seeds, which significantly improves the sowing efficiency and uniformity.

[0048] The timely and accurate delivery of grass seeds is achieved through the release member 5. The thrust of the soil on the movable plate 56 triggers the movement of the blocking block 53, so that the temporary storage groove 43 is connected with the sowing groove 51, and the grass seeds fall into the soil. No additional power source is required, and the structure is simple and reliable. The closed cavity formed by the L-shaped blocking block 53 and the baffle 52 effectively prevents the grass seeds from accidentally falling during the insertion or lifting process. The reset mechanism ensures the recycling of the device. The triangular plug-in block further seals the sowing channel to avoid missing seeds. This insertion and sowing design adapts to different soil conditions and ensures the stability of sowing depth and density.
