Description
Technical Field
[0001] The utility model relates to the technical field of seeding machine drums, in particular to a novel structure of a seeding machine drum. Background Technique
[0002] When cultivating vegetable seedlings at present, pneumatic seeding machines are widely used. Pneumatic seeding machines are widely used in vegetable seedling cultivation. Their core components are drums on the rotating shaft and ventilation devices, and suction holes are opened on the drums. During operation, the drum rotates under the action of power, and the ventilation device is responsible for the adsorption and release of seeds to ensure that the seeds are accurately sown into each acupoint of the seedling tray.
[0003] In the existing seeding machine technology, most of the suction holes at the upper end of the drum are designed as round holes, which are suitable for adsorbing round seeds. Because under the action of suction, round seeds are easy to roll to the hole opening under the action of suction, partially enter the hole, and most adhere to the outside of the hole, realizing the precise sowing of single seeds. However, this design is not suitable for irregularly shaped solanaceous seeds because they do not roll, which easily leads to multiple seeds being adsorbed by one suction hole, causing multiple adsorption problems. This will result in uneven seeding, affecting seed germination and crop growth, thus reducing the seeding efficiency and crop yield.
[0004] Therefore, those skilled in the art have provided a novel structure of a seeding machine drum to solve the problems raised in the above background technique. Content of the Utility Model
[0005] The purpose of the content of the utility model is to solve the shortcomings existing in the prior art, and a novel structure of a seeding machine drum is proposed. By setting hemispherical seed suction heads, the flow of seeds around is promoted during the rotation of the drum, ensuring the precise adsorption of one seed per hole for solanaceous seeds at the seed suction ports, effectively avoiding multiple adsorption of multiple seeds, reducing the shutdown cleaning and re-seeding caused by multiple adsorption, improving the operation efficiency of the seeding machine, and improving the crop growth conditions due to uniform seeding, thereby contributing to increasing the final yield.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:

Seed suction ports are opened in the interiors of the plurality of seed suction heads. The outer shapes of the plurality of seed suction heads are hemispherical, conical or cylindrical;

[0009] Furthermore, the multiple air channels, communication holes and seed suction ports are interconnected with each other;
[0010] Through the above technical solution, through the connected design of the air channel, communication hole and seed suction port, it can ensure unobstructed air flow, thereby improving the adsorption and release efficiency of seeds, reducing blockage phenomena, and ensuring the stability and continuity of the seeding process.
[0011] Furthermore, a shaft hole is provided in the middle of the interior of the drum;
[0012] Through the above technical solution, providing a shaft hole inside the drum helps to support the axis of the drum, improve the stability and rotation accuracy of the drum, thereby reducing vibration and ensuring the uniformity and accuracy of the seeding process.
[0013] Furthermore, the multiple external threads are all threadedly connected to the internal threads;
[0014] Through the above technical solution, the threaded connection design of the external thread and the internal thread can ensure the tight fit of the components, improve the structural stability and durability of the equipment, avoid loosening and damage, and enhance the reliability of the whole machine.
[0015] Furthermore, the distance between the side end faces of the multiple seed suction heads and the outer wall of the drum is within 2 mm;
[0016] Through the above technical solution, setting the distance between the seed suction head and the outer wall of the drum within 2 mm helps to improve the accuracy and efficiency of the seed suction head, reduce the phenomena of seed omission and misseeding, and ensure the accurate number of seeds adsorbed per hole.
[0017] Furthermore, the multiple seed suction heads are evenly spaced on the outer wall of the drum, and the angle between the seed suction heads in each row is 60 degrees;
[0018] Through the above technical solution, the design of uniform spacing and 60-degree angle ensures the uniform distribution of seeds on the drum, improves the accuracy and consistency of seeding, optimizes the seeding effect, and improves the growth uniformity and final yield of crops.

[0029] Next, the technical solutions in the specific embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the specific embodiments of the utility model. Obviously, the described specific embodiments are only a part of the specific embodiments of the utility model, rather than all of the specific embodiments. Based on the specific embodiments of the utility model, all other specific embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the utility model.
[0030] Referring to Figures 1-5 , a specific embodiment provided by the present utility model: a novel seeding machine drum structure, including a drum 1 and multiple seed suction heads 8. Air channels 2 are evenly spaced on the inner and outer sides of the drum 1. Internal threads 4 are evenly spaced on the outer wall of the drum 1. One end face of each of the multiple seed suction heads 8 is fixedly connected with a connecting pipe 5. Connecting holes 6 are provided inside each of the multiple connecting pipes 5. External threads 7 are provided outside each of the multiple connecting pipes 5. Seed suction ports 9 are provided inside each of the multiple seed suction heads 8. The shapes of the multiple seed suction heads 8 are hemispherical, conical or cylindrical. By providing the hemispherical seed suction heads 8, the flow of surrounding seeds is promoted during the rotation of the drum 1, ensuring the accurate adsorption of one seed per hole for solanaceous seeds at the seed suction port 9, effectively avoiding the multiple adsorption of multiple seeds, reducing the shutdown cleaning and re-seeding caused by multiple adsorption, improving the operation efficiency of the seeding machine, and improving the crop growth conditions due to uniform seeding, thereby contributing to increasing the final yield.
[0031] The multiple air channels 2, connecting holes 6 and seed suction ports 9 are interconnected. Through the interconnected design of the air channels, connecting holes 6 and seed suction ports 9, the smooth flow of air can be ensured, thereby improving the adsorption and release efficiency of seeds, reducing blockage phenomena, and ensuring the stability and continuity of the seeding process. A shaft hole 3 is provided in the middle of the interior of the drum 1. Providing the shaft hole 3 inside the drum 1 helps to support the axis of the drum 1, improving the stability and rotation accuracy of the drum 1, thereby reducing vibration and ensuring the uniformity and accuracy of the seeding process. The multiple external threads 7 are all threadedly connected with the internal threads 4. The threaded connection design of the external threads 7 and the internal threads 4 can ensure the tight fit of the components, improving the structural stability and durability of the equipment, avoiding loosening and damage, and enhancing the reliability of the whole machine. The distance between one end face of each of the multiple seed suction heads 8 and the outer wall of the drum 1 is within 2 mm. Setting the distance between the seed suction heads 8 and the outer wall of the drum 1 within 2 mm helps to improve the accuracy and efficiency of the seed suction heads 8, reducing the phenomena of seed omission and misseeding, and ensuring the accurate number of seeds adsorbed per hole. The multiple seed suction heads 8 are evenly spaced on the outer wall of the drum 1, and the angle between the seed suction heads 8 in each row is 60 degrees. The design of even spacing and 60-degree angle ensures the uniform distribution of seeds on the drum 1, improving the accuracy and consistency of seeding, optimizing the seeding effect, and enhancing the growth uniformity and final yield of crops.
[0032] Working principle: When this structure is in use, the drum 1 is sleeved on the upper end of the rotating shaft of the seeder, and the air duct is connected to the air exchange structure of the seeder. When the drum 1 rotates, the hemispherical seed suction head 8 at the upper end of the drum 1 promotes the flow of surrounding seeds, ensuring the precise adsorption of the seed suction port 9 to the solanaceous seeds, avoiding the multiple adsorption of multiple seeds, thereby improving the accuracy and uniformity of sowing. When sowing other types of seeds, the internal thread 4 at the upper end of the drum 1 can be rotationally disassembled from the external thread 7 at the upper end of the connecting pipe 5, so that the seed suction head 8 can be quickly switched to a conical or cylindrical seed suction head 8 according to the type and characteristics of the seeds, enhancing the adaptability of the seeder.
[0033] Finally, it should be noted that the above is only the preferred specific embodiment of the present invention and is not used to limit the present invention.
