Description

Technical Field

[0001] The utility model relates to the field of agricultural technology promotion, in particular to a particle seed sowing device. Background Art

[0002] With the growth of population and the increase of food demand, traditional manual farming can no longer meet the needs of modern people for more and higher quality food production. Therefore, with the help of science and technology, agricultural equipment production is undergoing a huge technological iteration in response to different agricultural needs and sustainable development considerations. In terms of sowing, traditional manual sowing is time-consuming and labor-intensive, and the emergence of seeders has greatly alleviated this problem.

[0003] However, general seeders still have some common problems. For example, when sowing granular seeds, the seeder cannot classify the seed size, so the seed density during sowing is uneven, causing growth competition and inconsistent growth cycles, which in turn reduces the survival rate of the seeds. At the same time, for some seeds that cannot grow and survive in the surface soil, there is a lack of soil-turning mechanism to allow the seeds to be planted deep into the soil to increase their survival rate. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a granular seed sowing device, aiming to improve the problems of uneven density and inability of some seeds to survive in the surface soil when sowing seeds.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a granular seed sowing device, including a support frame, a bottom outer wall of the support frame is provided with a plurality of fixed piles, the top outer walls of the fixed piles are fixedly connected with fixed rings, the inner walls of the fixed rings are rotatably connected with rollers, the side walls of the rollers are provided with openings, a motor is mounted on the left outer wall of the roller, the output end of the motor is embedded in the left outer wall of the roller, the bottom of the motor is fixedly connected to the wedge block, the bottom end of the wedge block is fixedly connected to the bottom outer wall of the support frame, a feed port is provided on the right outer wall of the roller, a plurality of baffles are provided on the bottom outer wall of the support frame, the outer walls of the baffles are fixed with rivets, a discharge port is provided at the bottom end of the support frame, and a soil turning assembly is provided on the support frame.

[0030] The following will refer to the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0032] Reference Figure 1-5 The utility model provides an embodiment: a granular seed sowing device, including a support frame 8, a bottom outer wall of the support frame 8 is provided with a plurality of fixed piles 17, the top outer walls of the fixed piles 17 are fixedly connected with fixed rings 3, the inner walls of the fixed rings 3 are rotatably connected with rollers 4, the side walls of the rollers 4 are provided with openings 5, a motor 2 is mounted on the left outer wall of the roller 4, the output end of the motor 2 is embedded in the left outer wall of the roller 4, the bottom of the motor 2 is fixedly connected to a wedge 18, the bottom end of the wedge 18 is fixedly connected to the bottom outer wall of the support frame 8, a feed port 7 is provided on the right outer wall of the roller 4, a plurality of baffles 13 are provided on the bottom outer wall of the support frame 8, the outer walls of the baffles 13 are fixed with rivets 14, a discharge port 15 is provided at the bottom of the support frame 8, and a soil turning component is provided on the support frame 8.

[0033] Specifically, the support frame 8 can be a frame structure, which plays the role of supporting the drum 4 and ensuring that the discharge port 15 is off the ground. The fixed piles 17 can be extended and retracted up and down independently to adjust the inclination angle of the drum 4. The openings 5 ​​are provided with a variety of different diameters to facilitate the classification and collection of seeds of different sizes. The wedge block 18 can slide accordingly to keep the motor 2 and the drum 4 on the same axis. The seeds fall through the openings 5 ​​on the drum 4 into the space formed by the support frame 8 and the baffle 13 below. The baffle 13 is fixed on the periphery with rivets 14. The user can decide which size of seeds to sow by himself, and this function can be achieved by opening the discharge port 15 under the corresponding seed holding space.

[0034] The soil-turning assembly includes a soil-turning roller 1 and a soil-turning tail plate 12. A rotating shaft 16 is provided at the left end of the support frame 8, and the outer wall of the rotating shaft 16 is rotatably connected to the soil-turning roller 1. A fixed rod 9 is provided at the upper right end of the support frame 8, and one end of the fixed rod 9 is fixed to the baffle 13. A sliding rod 19 is slidably connected to the lower right end of the support frame 8, and the middle part of the sliding rod 19 is rotatably connected to the soil-turning tail plate 12. A threaded rod 10 is rotatably connected to the middle part of the fixed rod 9, and the bottom of the threaded rod 10 passes through the soil-turning tail plate 12 and is threadedly connected to the sliding rod 19.

[0035] Specifically, by moving the component 11, the entire sowing device starts to move, and the tilling roller 1 starts to work to till the land on the path, so that the seeds can be sown deeper in the soil, avoiding the problem that some seeds cannot germinate and grow in the surface soil. While moving, the soil tail plate 12 is set to a suitable height by rotating the threaded rod 10. The soil tail plate 12 can cover the land turned over by the tilling roller 1 in front of the path, so that it covers the surface and covers the seeds, which makes it easier for the seeds to absorb nutrients deep in the soil and maintain the uniform beauty of the cultivated field.

[0036] A valve 6 is installed at the bottom of the feed inlet 7.

[0037] Specifically, the degree of opening and closing of the valve 6 is controlled to reasonably control the amount of feed. Too little instantaneous feed will lead to low sowing efficiency, while too much instantaneous feed will easily cause the opening 5 to be blocked or the seeds cannot fall into the opening 5 of the corresponding size.

[0038] A moving assembly 11 is installed on the right portion of the support frame 8 .

[0039] Specifically, the moving assembly 11 is used to realize the movement of the entire spreading device.

[0040] The bottom end of the soil-turning roller 1 and the bottom end of the moving assembly 11 should be located on the same horizontal line.

[0041] Specifically, the height change of the bottom end of the soil turning roller 1 will simultaneously change the turning depth and the force required when turning the soil.

[0042] The top end of the threaded rod 10 is provided with a rotating structure for facilitating the rotation of the rod body.

[0043] Working principle: Turn on the motor 2, which drives the roller 4 to start rotating on the inner wall of the fixed ring 3. Pour seeds from the feed port 7, and the seeds will naturally fall into the roller 4. Under the rotation of the roller 4, the seeds will quickly fall into the opening 5 whose diameter is larger than the seed size, and fall into the space formed by the support frame 8 and the baffle 13 below. Then, under the action of the moving component 11, the sowing device starts to move, and the soil-turning roller 1 starts to turn the soil to ensure that the seeds can be sown into the soil. At this time, open the discharge port 15 corresponding to the seed size to be sown, and start the sowing work. After the sowing is completed, the soil tail plate 12 will cover the land turned over by the soil-turning roller 1 and cover the seeds.
