Description

Technical Field

[0001] This utility model relates to the field of sesame planting technology, specifically a sesame mulching and pressing hole sowing machine. Background Technology

[0002] Sesame, as an important oil crop, is widely regarded as an effective means to improve yield and quality due to its mulching technology, which has good heat preservation, moisture retention and weed suppression effects. In actual planting, sesame mulching is usually broken down into several independent operation steps: first, the mulch film is laid manually or by special machinery; then, holes are punched or pressed into the mulch film by hand; and finally, the seeds are sown by spot sowing or manual broadcasting.

[0003] While this segmented operation method achieves functional division to some extent, it also exposes many problems. Due to the fragmentation of each process, the entire planting process requires multiple field operations, which is not only cumbersome but also significantly reduces production efficiency and increases the workload of workers. At the same time, due to the lack of close connection between each link, the seed hole position and the sowing point often cannot be accurately matched, resulting in seeds being sown outside the film or seed holes being left empty, which in turn leads to missed sowing and uneven emergence, directly affecting the final seedling quality and planting benefits. In addition, the reliance on a large amount of manual labor also increases planting costs, making this model difficult to adapt to the growing demand for large-scale and intensive agricultural production in modern agriculture, and restricting the development of mechanization and standardization in sesame planting. Therefore, we propose a new sesame film-covered and hole-pressing sowing machine. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sesame mulching and pressing hole sowing machine, which solves the problems of low efficiency, high labor costs, inaccurate sowing position, and uneven seedling emergence caused by segmented operation in existing technologies.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through a highly integrated joint operation system, changes the traditional segmented operation mode. Driven by a traction device, the machine completes all processes of tilling, mulching, pressing holes, and sowing in one go, significantly reducing the number of times the agricultural machinery needs to enter the field, increasing the operation efficiency several times, effectively reducing time costs and labor consumption. Moreover, the rotation of the traveling wheels not only provides forward power but also synchronously drives the pressing wheel to rotate, so that the pressing protrusions form regular planting holes on the film surface the moment after mulching. This effectively solves the problem of seeds being sown outside the film or in empty holes, ensuring uniform emergence and laying a solid foundation for stable and high sesame yields. It perfectly meets the urgent needs of modern agriculture for large-scale, standardized, and intensive production and has extremely high promotion value. The adjustment component allows operators to adjust the longitudinal position of the mulch film in real time during driving. By precisely controlling the tension of the mulch film, it ensures that it can fit tightly to the ground under various terrain conditions, greatly improving the adaptability and stability of the operation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model embodiment provides a sesame mulching and hole-pressing sowing machine. Please refer to [link / reference]. Figures 1-5 The machine includes a frame 1, on which an adjustment component 2 and multiple pressing components 3 for pressing seed holes on the film surface are respectively provided. The adjustment component 2 includes a threaded rod 21, which is rotatably connected to the inside of the frame 1. One end of the threaded rod 21 is threadedly connected to a threaded sleeve 22. The rotation of the threaded rod 21 drives the threaded sleeve 22 to move linearly, thereby realizing the precise position adjustment of the film coating component 4. The end of the threaded sleeve 22 away from the threaded rod 21 is fixedly connected to the film coating component 4. The mulching assembly 4 includes a mulching support 41 and a pressing wheel 42. The top of the mulching support 41 is fixedly connected to the threaded sleeve 22. A mulch film roll 44 is provided on the mulching support 41. An inclined frame 43 is fixedly connected to the side wall of the mulching support 41. The pressing wheel 42 is rotatably connected to the outer side wall of the inclined frame 43 to press the mulch film into the soil to fix it.

[0018] It should be noted that the plastic film roll 44 is provided with rotating grooves 46 at both ends, and the rotating grooves are as follows: Figure 5As shown, the mulch film roll is installed between the fixing member 45 and the film covering bracket 41. The fixing member 45 is a rod with a threaded section. The fixing member 45 is threadedly connected to the film covering bracket 41. The end of the fixing member 45 away from the threaded section is fitted with the rotation groove 46 of the mulch film roll 44. By setting fixing members 45 at both ends of the mulch film roll 44, it can rotate normally while achieving the purpose of limiting its installation. When the mulch film on the mulch film roll 44 needs to be replaced or replenished, only the fixing member 45 needs to be removed for replacement.

[0019] Furthermore, a sliding rod 23 is fixedly connected to the top of the film-coating bracket 41, and a corresponding groove 24 is provided at the bottom of the frame 1. The sliding rod 23 is slidably disposed in the groove 24 to provide guidance and support for the movement of the film-coating assembly 4 and ensure its smooth movement.

[0020] Furthermore, multiple connecting arms 1 5 and multiple connecting arms 2 6 are fixedly connected to the outer side wall of the frame 1. One end of each of the multiple connecting arms 1 5 is fixedly connected to a soil turner 7 for loosening and leveling the land. The bottom of each of the multiple connecting arms 2 6 is fixedly connected to a rotating seat 8 and a fixed seat 9.

[0021] Furthermore, a rotating shaft 10 is rotatably connected to the rotating base 8, and one end of the rotating shaft 10 is fixedly connected to a traveling wheel 11 for supporting the frame 1 and rolling forward, the rotation of which provides power to the cavitation assembly 3.

[0022] Furthermore, the pressing assembly 3 includes a pressing wheel 31, which is fixedly connected to the other end of the rotating shaft 10 away from the traveling wheel 11 and rotates synchronously with the traveling wheel 11. A plurality of pressing protrusions 32 for periodically pressing out seed holes are fixedly connected to the circumferential surface of the pressing wheel 31.

[0023] It should be noted that the setting of the rotating shaft 10 enables the pressing wheel 31 to be synchronized with the machine's forward speed, and the pressing wheel 31 can be replaced with pressing protrusions 32 of different spacing according to the needs of different inter-species spacing.

[0024] Furthermore, a sowing assembly 12 is fixedly connected to the fixed base 9. The sowing assembly 12 includes a seed box 121 for storing seeds. A seed metering device 122 is provided on the side of the seed box 121, and a seed guide tube 123 for guiding seeds into the seed holes is provided at the bottom of the seed metering device 122.

[0025] It should be noted that the seed metering device 122 is a hole wheel type seed metering device, which can quantitatively discharge sesame seeds. Combined with the seed guide tube 123, the seeds are sown at the same time as the holes are pressed out.

[0026] Furthermore, a motor 13 for providing rotational power is fixedly connected to the top of the frame 1. The output end of the motor 13 is fixedly connected to the end of the threaded rod 21 away from the film-coating bracket 41, driving the threaded rod 21 to rotate.

[0027] Furthermore, a traction frame 14 for connecting a traction power source is fixedly connected to the side of the frame 1 near the connecting arm 5.

[0028] Working principle: The machine moves forward under the traction of a tractor or other power source and completes a series of continuous sowing operations in sequence. The soil turner 7 on the connecting arm 5 first loosens and flattens the soil to prepare the seedbed for subsequent work. Next is the mulching. The mulch roll on the mulch support 41 unfolds and the mulch roll on the inclined frame 43 is pressed tightly onto the flattened soil surface by the pressing roller 42. The longitudinal position of the mulch support 41 can be precisely adjusted by the motor 13 driving the threaded rod 21 to ensure that the mulch is in the best tension and coverage position under different terrain conditions.

[0029] While the film is being laid, the pressing and sowing processes are carried out simultaneously. The movement of the machine drives the traveling wheel 11 to rotate, which in turn drives the pressing wheel 31 at the other end to rotate through the rotating shaft 10. The pressing protrusions 32 on the circumferential surface of the pressing wheel 31 press out regular holes on the covered film. At the same time as the holes are pressed out, the sowing component 12, which is fixed on the nearby fixed seat 9, starts to work. The seeds in the seed box 121 are measured by the seed metering device 122 and accurately put into the holes that have just been pressed out through the seed guide tube 123 to complete the sowing. This realizes the combined operation of turning the soil, laying film, pressing holes and sowing, which greatly improves the efficiency and quality of sesame sowing.
