However, in practical applications, some seeds are small and have a certain degree of fluidity. When the feeding roller rotates, the seeds will flow downwards under the influence of gravity, causing the sowing speed to become uncontrollable and resulting in seed waste. Utility Model Content

[0035] Reference Figures 1 to 5 This utility model proposes a seeding mechanism 100.

[0036] In this embodiment of the utility model, the sowing mechanism 100 includes: a mounting base 10; a seed hopper 20, which is mounted on the mounting base 10 and forms a seed cavity 20a and a discharge port 20b communicating with the seed cavity 20a; a feeding roller 30, which is disposed in the seed cavity 20a and rotatably connected to the seed hopper 20; and

[0037] Material limiting component 40 is disposed in the seed material bin 20 and is combined with the feeding roller 30 to form a material drop gap 40a. The material limiting component 40 can move toward or away from the feeding roller 30 to reduce or expand the material drop gap 40a.

[0038] Specifically, in this application, the mounting base 10 is made of metal profile and is used to install and fix the various components of the sowing mechanism 100. The bottom of the mounting base 10 is machined with multiple connecting holes, through which screws can pass to fix the mounting base 10. The seed hopper 20 can be made of metal or plastic material and has a cone-shaped shell structure. The shell-shaped seed hopper 20 has a seed hopper 20 and a discharge port 20b connecting the seed hopper 20. The discharge port 20b is opened at the bottom of the seed hopper 20, and its diameter can be set according to actual needs.

[0039] The feeding roller 30 includes a feeding drive motor (not shown) and a wheel body. The feeding drive motor can be a servo motor or a stepper motor. The feeding drive motor is fixedly mounted on the mounting base 10 by screws. The seed hopper 20 has a through hole along its edge that communicates with the seed chamber 20a. The wheel body has a connecting shaft hole. The output shaft of the feeding drive motor passes through the through hole and the connecting shaft hole to fix the wheel body to the seed hopper 20. Under the drive of the feeding drive motor, the wheel body can rotate in the seed chamber 20a to convey the seeds in the seed chamber 20a toward the discharge port 20b.

[0040] In this application, the seeds to be sown are placed in the seed chamber 20a of the seed hopper 20. When sowing is required, the feeding roller 30 rotates, and the seeds in contact with it are conveyed to the side of the discharge port 20b through the discharge gap 40a under the action of friction of the feeding roller 30. Under the action of gravity, the seeds are sown onto the predetermined land through the discharge port 20b. In this application, the limiting component 40 and the feeding roller 30 are combined to form the discharge gap 40a. The size of the discharge gap 40a can be adjusted according to the sowing speed, that is, the number of seeds falling into the discharge port 20b per unit time can be adjusted by the size of the discharge gap 40a. In this way, the sowing speed and the number of seeds sown per unit time can be adjusted. On the one hand, it can not only avoid the situation that too many seeds in a single planting area exceed the planting specifications and improve the sowing effect, but also greatly reduce seed waste.

[0041] Specifically, in this embodiment, the limiting component 40 includes a limiting plate 41 and a torsion spring. The limiting plate 41 includes a plate body and a connecting shaft connecting opposite sides of the plate body. A rotating shaft hole is provided on the seed hopper 20, and the connecting shaft is rotatably fitted into the rotating shaft hole. The torsion spring is elastically connected to the connecting shaft and the seed hopper 20. Under the action of the torsion spring, the limiting plate 41 has a tendency to rotate toward the feeding roller 30. In this application, the limiting plate 41 and the feeding roller 30 form a dropping gap 40a, which can be understood as the distance from the surface of the limiting plate 41 to the surface of the feeding roller 30. The width of the dropping gap 40a should be slightly less than the thickness of a single seed, so that when the feeding roller 30 is not rotating, the seed will not fall from the dropping gap 40a to the dropping port 20b. When sowing seeds, the feeding roller 30 rotates, and under the action of its friction, the seeds are continuously conveyed to one side of the limiting plate 41. The seeds accumulate in the drop gap 40a. The feeding roller 30 rotates, and the seeds continue to accumulate. Under the continuous interaction of the seeds, the limiting plate 41 overcomes the elastic force of the torsion spring and rotates towards the side away from the feeding roller 30. That is, the width of the drop gap 40a is continuously expanding. When the width expands to a certain value, the seeds can fall from the drop gap 40a to the drop port 20b.

[0042] In this application, the limiting component 40 has a simple structure, and the limiting plate 41 and the service torsion spring rotate towards the side away from the feeding roller 30. The tendency of the torsion spring to rotate changes with the size of the seed, that is, the width of the dropping gap 40a can be adapted to the size of the seed particle size. Thus, the sowing mechanism 100 has good compatibility and practical performance.

[0043] In one embodiment of this utility model, a plurality of guide grooves 41a are recessed on the surface of the limiting plate 41, wherein the cross-section of the guide grooves 41a is semi-circular, and the plurality of guide grooves 41a are spaced apart along the width direction of the limiting plate 41. By providing a plurality of guide grooves 41a, the falling seeds can be guided, making the seeds falling into the discharge port 20b flow more evenly and the sowing effect better.

[0044] In this application, the mounting base 10 is provided with a slot 10a, which is L-shaped and extends through the upper surface of the mounting base 10. A snap-fit ​​protrusion 21 is formed on the side of the seed hopper 20, which is embedded in the slot 10a to connect the seed hopper 20 and the mounting base 10. This makes the assembly and disassembly of the seed hopper 20 relatively simple, allowing users to easily remove the seed hopper 20 from the mounting base 10 for cleaning or adding seeds.

[0045] In this application, the seed hopper 20 is further provided with a deceleration protrusion 22, which is cylindrical and partially located within the seed cavity 20a. The feeding roller 30 can abut against the surface of the deceleration protrusion 22. By providing this deceleration protrusion 22, this application can reduce the rotation speed of the feeding roller 30, preventing it from rotating too fast and making the sowing speed more suitable for actual needs.

[0046] This utility model also proposes an integrated agricultural planting device 1, which includes a frame 200 and a power supply device 300, a hole-digging mechanism 400, a cutting mechanism 500, and a sowing mechanism 100 installed on the frame 200. The specific structure of the sowing mechanism 100 is as described in the above embodiments. Since this integrated agricultural planting device 1 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The frame 200 can be formed by welding or screw splicing of metal profiles. The bottom of the frame 200 is provided with four moving wheels (not shown in the figure) to facilitate the user to move the integrated agricultural planting device 1 on the planting land. The hole-digging mechanism 400 includes a lifting linear module 410, a hole-drilling drive motor 420, and a hole-drilling threaded rod 430. The lifting linear module 410 is installed in the middle of the frame 200 and located at the front end of the sowing mechanism 100. That is, in the direction of movement of the integrated agricultural planting device 1, the lifting linear module 410 is located in front of the sowing mechanism 100. The drilling drive motor 420 is driven by the lifting linear module 410, and the drilling threaded rod 430 is driven by the output shaft of the drilling drive motor 420.

[0047] In practical applications, when the frame 200 moves to the preset planting area, the lifting linear module 410 drives the drilling drive motor 420 to move downwards. At the same time, the drilling drive motor 420 drives the drilling threaded rod 430 to rotate. As the lifting linear module 410 moves downwards, the drilling threaded rod 430 drills a deep pit for sowing on the planting ground. After drilling to the preset depth, the lifting linear module 410 drives the drilling drive motor 420 to move upwards, and the frame 200 continues to move forward, so that the material discharge port 20b of the sowing mechanism 100 moves above the planting pit and puts seeds into the planting pit. After sowing is completed, the frame 200 continues to move forward and repeats the above operation. In this way, the sowing efficiency of the integrated agricultural planting equipment 1 is higher.

[0048] It is understood that in this application, the power for the movement of the frame 200 may originate from itself, that is, the four moving wheels are connected to a motor (not shown) via a transmission rod (not shown), and the motor drives the four moving wheels to rotate, thereby driving the frame 200 to move. Alternatively, the power for the movement of the frame 200 may originate from an external moving trolley or other power system, which is not specifically limited here.

[0049] Furthermore, the cutting mechanism 500 includes a cutting drive motor 510 and a rotary cutter 520. Specifically, a mounting rail (not shown) is provided at the front end of the frame 200, and a portion of the mounting rail extends obliquely toward the side away from the sowing mechanism 100. The cutting drive motor 510 can be a servo motor or a stepper motor. The cutting drive motor 510 is fixed to the frame 200 by screws and is located at the front end of the drilled threaded rod 430. The rotary cutter 520 is connected to the output shaft of the cutting drive motor 510 via a coupling. When the frame 200 moves on the planting ground, the cutting drive motor 510 drives the rotary cutter 520 to rotate, thereby cutting the weeds in the area 200 passes through, and clearing the planting ground. In this application, the mounting guide rail is formed with multiple threaded mounting holes spaced apart by machining. The multiple threaded mounting holes are spaced apart along the extension direction of the mounting guide rail. The cutting drive motor 510 can be fixed to any of the threaded mounting holes by screws. At the same time, since the mounting guide rail is inclined downward toward the frame 200, the position of the cutting drive motor 510 in the height direction is adjustable. In this way, the rotary cutter 520 can clean weeds of different heights.

[0050] Furthermore, the power supply unit 300 includes a solar panel 310 and a battery 320 mounted on the frame 200. The battery 320 is electrically connected to the solar panel 310, the drilling drive motor 420, the lifting linear module 410, and the cutting drive motor 510 via electronic connection wires. In actual use, the solar panel 310 uses sunlight to charge the battery 320, which in turn supplies power to electrical equipment such as the drilling drive motor 420, the lifting linear module 410, the cutting drive motor 510, and the feeding drive motor, enabling the integrated agricultural planting equipment 1 to operate normally with reduced energy consumption.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
