[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] Example 1:

[0024] As attached Figure 1 To be continued Figure 6 As shown:

[0025] This utility model provides a rolling device for quantitative sowing in agriculture, comprising: a machine frame 1, a protective cylinder 101 in the middle of the machine frame 1, a tillage roller 2 rotatably connected inside the protective cylinder 101, a connecting bracket 3 fixedly connected to the bottom rear side of the machine frame 1, four swing frames 4 hinged at equal intervals on the connecting bracket 3, a wheel frame 5 fixedly connected in the middle of the swing frames 4, a quantitative sowing wheel 8 rotatably connected to the wheel frame 5, an adjusting rod 6 hinged to the top rear side of the wheel frame 5, a rolling frame 11 hinged to the bottom rear side of the swing frames 4, a rolling rod 12 hinged to the middle rear side of the top of the rolling frame 11, and a sliding bushing 13 slidably connected to the top of the rolling rod 12. Specifically, the protective cylinder 101 in the middle of the machine frame 1 protects the internally rotatably connected tillage roller 2. When the tillage roller 2 rotates, it performs preliminary tillage and crushing of the soil, preparing it for subsequent... The sowing operation creates suitable soil conditions, making the soil looser, which is conducive to seed germination and growth. A connecting bracket 3 is fixedly connected to the bottom rear side of the equipment frame 1. Four swing frames 4 are hinged at equal intervals on the connecting bracket 3. The connecting bracket 3 serves to connect the equipment frame 1 and the swing frames 4, providing a mounting base for the swing frames 4. The swing frames 4 can swing around the hinge points on the connecting bracket 3. This design allows the wheel frame 5 and the quantitative sowing wheel 8 to adjust their height according to the undulation of the ground, ensuring that the quantitative sowing wheel 8 always maintains good contact with the ground, thereby ensuring the consistency of sowing depth. The wheel frame 5 is fixedly connected to the middle of the swing frame 4, and the quantitative sowing wheel 8 is rotatably connected to the wheel frame 5. The wheel frame 5 provides support and mounting position for the quantitative sowing wheel 8, enabling it to rotate stably. The quantitative sowing wheel 8 is the core component for realizing the quantitative sowing function. It has a quantitative separation component inside, which can accurately control the number of seeds to be sown, avoiding sowing that is too dense or too sparse.

[0026] The wheel frame 5 has an adjusting rod 6 connected to the shaft joint 502 on the rear side of the top. Four connecting seats 102 are evenly spaced on the rear top of the equipment frame 1. Adjusting shaft seats 7 are hinged to the connecting seats 102. An adjusting bushing 701 is rotatably connected inside the adjusting shaft seat 7. The front and rear ends of the adjusting bushing 701 are hexagonal nuts. The adjusting bushing 701 is threaded onto the threaded rod 601 connected to the rear end of the adjusting rod 6. A limiting rod 103 is fixedly connected to the rear bottom of the equipment frame 1. The limiting rod 103 is located at the rear bottom of the swing frame 4 and its function is to adjust the load by rotation. The bushing 701, being threadedly connected to the threaded rod 601 at the rear end of the adjusting rod 6, can change the length of the adjusting rod 6. The adjusting rod 6 is connected to the wheel frame 5, so the height of the wheel frame 5, the swing frame 4, and the quantitative seeding wheel 8 can be adjusted to adapt to different seeding depth requirements. A limit rod 103 is fixedly connected to the bottom rear side of the equipment frame 1. The limit rod 103 is located at the bottom rear end of the swing frame 4. The function of the limit rod 103 is to limit the swing frame 4 from swinging downwards excessively, preventing the quantitative seeding wheel 8 from sinking too deep into the soil, thereby protecting the equipment and ensuring that the seeding depth is within a reasonable range.

[0027] The swing frame 4 has a connecting shaft seat 401 fixedly installed at the top front end, and a sliding bushing 13 rotatably connected to the connecting shaft seat 401. An "L"-shaped rear connecting arm 402 is fixedly connected to the bottom front end of the swing frame 4. A rolling frame 11 is hinged to the front end of the rear connecting arm 402. A rolling wheel 1101 is rotatably connected to the front end of the rolling frame 11. A rolling tie rod 12, hinged at the middle of the rear side of the top of the rolling frame 11, is slidably connected at its top end to the sliding bushing 13. A support spring 14 is sleeved on the outer side of the rolling tie rod 12. Specifically, when the equipment moves in the field, the rolling wheel 1101 rolls the sown soil. The rolling frame 11... The rear connecting arm 402 is hinged to the swing frame 4, which can swing up and down according to the ground conditions to ensure that the rolling roller 1101 always keeps in contact with the ground for rolling operations. The support spring 14 provides upward support force for the rolling frame 11, so that the rolling roller 1101 can apply appropriate pressure to the soil during the rolling process, compact the soil, and make the seeds in close contact with the soil, which is conducive to the seeds absorbing water and nutrients. At the same time, it can avoid damage to the soil structure or seeds due to excessive pressure. Meanwhile, the rotatable connection between the sliding bushing 13 and the connecting shaft seat 401 and the sliding connection with the rolling tie rod 12 provides flexible space for the up and down swing of the rolling frame 11.

[0028] Among them, a limit lever 501 is fixedly connected to the bottom front side of the wheel frame 5. The bottom of the limit lever 501 is circular. The interior of the quantitative seeding wheel 8 is hollow and equipped with a quantitative separation component. Twelve seeding nozzles 801 are evenly spaced on the annular outer wall of the quantitative seeding wheel 8. A sealing cover 9 is rotatably connected to the seeding nozzle 801. A control lever 901 is fixedly connected to one end of the rotating shaft of the sealing cover 9. The end of the control lever 901 is arc-shaped and matches the bottom end of the limit lever 501 on the wheel frame 5. A guide rod 902 is fixedly connected to the outer wall of the arc-shaped end of the control lever 901 of the sealing cover 9. A return spring 10 is sleeved on the guide rod 902. The end of the guide rod 902 is slidably connected to the limit plate 802 on the outer wall of the quantitative seeding wheel 8, which corresponds to the position of the seeding nozzles 801. Specifically, When the quantitative seeding wheel 8 rotates, the limit lever 501 contacts the control lever 901. When the limit lever 501 moves the control lever 901, the sealing cap 9 rotates around the axis of the seeding spout 801, thereby opening the seeding spout 801 and allowing the seeds separated by the quantitative separation component to be sown into the soil through the seeding spout 801. When the limit lever 501 disengages from the control lever 901, the sealing cap 9 automatically closes the seeding spout 801 under the action of the return spring 10, preventing seeds from falling prematurely or foreign objects from entering the seeding spout 801. The guide rod 902 and the limit plate 802 guide and limit the movement of the sealing cap 9, ensuring that the sealing cap 9 can accurately open and close the seeding spout 801, improving the accuracy and stability of quantitative seeding.

[0029] The specific usage and function of this embodiment are as follows:

[0030] When using this agricultural quantitative seeding roller, first, put a sufficient amount of seeds into the quantitative seeding wheel 8, connect the equipment to the traction power source, start the traction power source, and slowly drag the equipment forward. At this time, the tillage roller 2 begins to rotate inside the protective cylinder 101 in the middle of the equipment frame 1, performing preliminary tillage and crushing of the soil. Then, according to the required sowing depth, adjust the height of the wheel frame 5 and the quantitative seeding wheel 8 by rotating the adjusting bushing 701 using a tool. Since the adjusting bushing 701 is threadedly connected to the threaded rod 601 at the rear end of the adjusting lever 6, the length of the adjusting lever 6 can be changed, thereby driving the wheel frame 5 and the quantitative seeding wheel 8 to rise or fall. As the equipment moves forward, the quantitative seeding wheel 8 rotates, and the wheel frame... The limiting lever 501 fixed at the bottom front interacts with the control lever 901 connected to the shaft of the closed mouth cover 9 in the quantitative seeding wheel 8 and the seeding duckbill 801. When the limiting lever 501 moves the control lever 901, the closed mouth cover 9 rotates around the shaft of the seeding duckbill 801 and opens. The seeds separated by the quantitative separation component are sown into the soil through the seeding duckbill 801. Then the rolling wheel 1101 begins to roll the soil after sowing. The rolling frame 11 is hinged to the swing frame 4 through the rear connecting arm 402 and can swing up and down according to the ground conditions to ensure that the rolling wheel 1101 always keeps in contact with the ground. The support spring 14 provides an upward support force for the rolling frame 11, so that the rolling wheel 1101 applies appropriate pressure to the soil.

[0031] Example 2:

[0032] At the bottom connection between the connecting bracket 3 and the equipment frame 1, a triangular reinforcing rib is welded along both the horizontal and vertical directions to increase the structural strength of this part and prevent deformation or breakage due to long-term stress.
