[0061] Please refer to Figure 1-6 , the present utility model provides a technical solution: a rice quantitative seeding device, and the seeding device includes:

[0062] Upper fixing plate 1;

[0063] Lower fixing frame 2, arranged below the upper fixing plate 1, and the lower fixing frame 2 is fixedly connected with an adapter frame 21;

[0064] Axle 5, arranged below the front side of the lower fixing frame 2, and plow wheels 6 are installed at both ends of the axle 5;

[0065] Drive mechanism 3, installed on the upper fixing plate 1, and the drive mechanism 3 is adapted to drive the axle 5 and the plow wheels 6 to rotate;

[0066] Seeding mechanism 4, arranged on the lower fixing frame 2 and the axle 5.

[0067] Refer to the attached Figure 1 In some embodiments, the drive mechanism 3 includes:

[0068] Diesel engine 31, fixed to the top of the upper fixing plate 1;

[0069] Diesel engine shaft 32, fixedly connected to the output end of the diesel engine 31;

[0070] First pulley 33, fixedly connected to the diesel engine shaft 32;

[0071] Two groups of brackets 34, spaced and fixed at both sides of the top edge of the upper fixing plate 1, bearings 341 are installed inside the brackets 34, and a driven shaft 342 is fixed inside the two groups of bearings 341;

[0072] Second pulley 35, fixedly connected to one end of the driven shaft 342;

[0073] First sprocket 36, fixed to the end of the driven shaft 342 away from the second pulley 35;

[0074] Drive belt 37, drivingly connected between the first pulley 33 and the second pulley 35.

[0075] Specifically, through the combination of the driving mechanism 3, the driving system has an efficient transmission effect. The diesel engine 31 transmits power to the first pulley 33 through the diesel engine shaft 32, and then transmits it to the second pulley 35 through the transmission belt 37, and finally drives the driven shaft 342 and the first sprocket 36 to operate. Compared with the traditional gear transmission, this transmission method is lighter and easier to maintain, with high transmission efficiency and strong stability. In addition, the design of the bracket 34 and the bearing 341 enables the driving mechanism 3 to run smoothly, reduce vibration and wear, thereby extending the service life of the equipment and reducing maintenance costs.

[0076] Reference Manual Attached Figure 2 In some embodiments, the sowing mechanism 4 includes:

[0077] A plurality of seeding shells 41 are fixedly connected to the surface of the lower fixing frame 2 at equal intervals;

[0078] Two groups of hangers 42 are fixed at intervals on both sides of the bottom edge of the upper fixed plate 1, and the wheel axle 5 is loosely fitted and penetrated inside the two groups of hangers 42;

[0079] A front support frame 43 is fixed to the bottom front side of the upper fixed plate 1;

[0080] A rear support frame 44 is fixed to the bottom rear side of the upper fixed plate 1;

[0081] The second sprocket 45 is fixed on the axle 5;

[0082] Chain 46 , the second sprocket 45 and the first sprocket 36 are connected to each other through the chain 46 .

[0083] Specifically, the design of the sowing mechanism 4 enhances the stability and accuracy of the sowing device. The sowing shell 41 is equidistantly fixed on the lower fixed frame 2 to ensure the uniformity of each sowing. The hanger 42 is used to support the axle 5 so that the axle 5 can rotate smoothly during sowing to avoid jamming. The design of the front support frame 43 and the rear support frame 44 avoids excessive tipping of the device and is not easy to tilt or offset. The second sprocket 45 and the chain 46 connect the axle 5 to the first sprocket 36, so that the power of the driving mechanism 3 can be smoothly transmitted to the axle 5, thereby driving the plow wheel 6 to roll and realizing the function of automatic sowing. This design can effectively improve the sowing efficiency, ensure uniform distribution of seeds, and avoid missed or re-seeding in traditional sowing methods.

[0084] Reference Manual Attached Figure 3 In some embodiments, the sowing shell 41 includes:

[0085] A material storage unit 411;

[0086] The material collecting portion 412 is fixedly connected to the bottom of the material storing portion 411;

[0087] The outer fixing ring 413 is fixedly connected to the bottom of the material gathering part 412;

[0088] The inner movable ring 414 is fixedly sleeved on the wheel axle 5, and the inner movable ring 414 is movably arranged inside the outer fixing ring 413.

[0089] Specifically, the design of the seeding housing 41 component can achieve precise quantitative seeding. The storage part 411 can hold more seeds, reducing the trouble of frequently adding seeds during the seeding process. The material gathering part 412 concentrates the seeds in the storage part 411 to a specific area, ensuring that the number of seeds is uniform each time of seeding. The combined design of the outer fixing ring 413 and the inner movable ring 414 further ensures the stable output of seeds. The inner movable ring 414 can drive the seeds to fall as the wheel axle 5 rotates, preventing seed blockage.

[0090] Refer to the attached Figure 3-4 In some embodiments, the inner cavity of the storage part 411 is of a square structure, and both the top and the bottom of the storage part 411 are of open structures. The inner cavity of the material gathering part 412 is of a frustum of a pyramid structure, and the bottom of the material gathering part 412 is connected to the inner side of the outer fixing ring 413. Specifically, this structural design makes the connection between the storage part 411 and the material gathering part 412 smoother, which can reduce the blockage of seeds during the flowing process. At the same time, the square storage part 411 can hold more seeds, improving the endurance of the device and reducing the need for frequently replenishing seeds. The frustum of a pyramid structure of the material gathering part 412 allows the seeds to gradually flow downward under the action of gravity, effectively guiding the seeds to the seeding port. This structure not only ensures the uniformity of seeds but also can control the seeding amount, avoiding over-seeding or under-seeding and improving the seeding accuracy.

[0091] Refer to the attached Figure 5 In some embodiments, a number of groups of transfer grooves 4141 are regularly arranged in a circular array on the surface of the inner movable ring 414. Specifically, the transfer grooves 4141 can play a role in quantitative seeding. Through these uniformly distributed transfer grooves 4141, the inner movable ring 414 can gradually release seeds in a certain quantity during the rotation process, avoiding a large number of seeds falling at one time, thereby achieving precise quantitative seeding. This design reduces the risk of seed blockage and ensures the smooth operation of the seeding device. In addition, the regular array design of the transfer grooves 4141 can also improve the uniformity of the seeding process, making the number of seeds at each seeding point the same, thus providing good conditions for the growth of rice.

[0092] In some embodiments, several groups of plow blades 61 are fixedly connected to the middle of the plow wheel 6 in a regular annular array. Specifically, the design of the plow blades 61 enhances the adaptability of the device in the field. By fixedly arranging the plow blades 61 in a regular annular array on the plow wheel 6, the device can slightly till the soil when traveling in the field, ensuring the sowing depth and soil coverage. This arrangement of the plow blades 61 increases the grip of the device and avoids slipping on soft or slippery ground. In addition, the plow blades 61 can slightly loosen the soil, which helps to fix and cover the seeds in the soil, thereby improving the germination rate of the seeds. This design is particularly suitable for the light tillage requirements of the soil during rice planting, ensuring a good sowing effect.

[0093] Specifically, during use, according to the actual usage requirements, the device can be connected to a walking vehicle through the connecting frame 21 and the coupling frame, so as to realize the movement of the device. It can also be connected to a control handle through the connecting frame 21 to achieve manual control.

[0094] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
