Description

Technical Field

[0001] The utility model relates to the technical field of agriculture, in particular to a seed selection device for agricultural sowing machinery. Background Art

[0002] Agriculture is an industry that utilizes the growth and development laws of animals and plants to obtain products through artificial cultivation.

[0003] Existing agricultural planting requires the use of a seeder. Before sowing, a selection operation is required to improve the success rate of subsequent planting. A corresponding rotating device is required for seed selection. Currently, when selecting wheat self-retained seeds, a sieve is often used for screening. However, during the screening process, many flat, incomplete, and large-particle seeds cannot be screened out by the sieve, resulting in poor seed selection results and affecting the germination rate of subsequent planting. In addition, screening will generate dust, polluting the surrounding environment. Therefore, we propose a seed selection device for agricultural sowing machinery. Utility Model Content

[0004] The purpose of the utility model is to provide a seed selection device for agricultural sowing machinery, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a seed selection device for an agricultural sowing machine, comprising a base, support plates fixed on both sides of the top of the base, a cylinder provided between the two support plates, a first servo motor fixed to the outer wall of one of the support plates, a drive shaft of the first servo motor passing through the support plate and fixedly connected to one side wall of the cylinder, and the other side wall of the cylinder being rotatably connected to the inner wall of the other support plate;

[0006] A notch is provided on one side of the top of the cylinder and a guide shell is fixed in the notch. A hollow shaft passes through the bottom of the cylinder. A first gear is fixedly mounted on the lower side of the outer wall of the hollow shaft. A second gear is engaged with the outer wall of the first gear. The second gear is fixed to the outer end of the transmission shaft of the second servo motor. The second servo motor is fixed to the bottom of the cylinder. A plurality of evenly distributed stirring rods are fixed to the outer wall of the hollow shaft and the stirring rods are placed in the cylinder.

[0007] By adopting the above technical solution, the seeds are introduced into the inner cavity of the cylinder, and water is continuously added. During the process of adding water, the second gear is driven to rotate by the second servo motor, thereby driving the first gear to rotate, and then driving the hollow shaft to rotate, thereby driving the stirring rod to stir the seeds, so that the unfull seeds and coatings can be lifted by the buoyancy of the water, and the continuous introduction of water can make the unqualified seeds floating on the water surface directly discharged along the guide shell, thereby realizing seed selection, improving the seed selection effect, and helping to avoid dust. After the seed selection is completed, the first servo motor is used to drive the cylinder to flip, so that the selected seeds can be poured out.

[0008] As a preferred embodiment of the present invention, the stirring rod is a hollow structure, the stirring rod is connected to the hollow shaft, a plurality of evenly distributed holes are opened on the top of the stirring rod, and the tail end of the hollow shaft is connected to the second water supply pipe through a rotary joint.

[0009] By adopting the above technical solution, water can be continuously supplied to the hollow shaft through the second water supply pipe, and then the water is discharged along the holes on the stirring rod, thereby longitudinally impacting the wheat seeds, so that the stirring effect of the wheat seeds can be further improved during stirring, which is conducive to further improving the effect of removing unqualified seeds from the seeds, and then further improving the seed selection effect.

[0010] As a preferred embodiment of the present invention, electric push rods are fixed to both sides of the top of the base, and the outer ends of the push rods are fixedly connected to the carrier plate.

[0011] By adopting the above technical solution, the electric push rod can be used to drive the carrier plate to lift and support the bottom of the cylinder, so that the cylinder has high stability when it is not overturned.

[0012] As a preferred embodiment of the present invention, a first water supply pipe is fixedly connected to the upper side of the outer wall of the cylinder.

[0013] By adopting the above technical solution, the provision of the first water supply pipe enables sufficient water to be introduced into the cylinder after the seeds are introduced into the cylinder.

[0014] As a preferred embodiment of the present invention, rubber sheets are fixed at the four corners of the bottom of the base.

[0015] By adopting the above technical solution and disposing the rubber sheet, the anti-slip performance of the entire device can be improved.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] The present invention relates to a seed selection device for agricultural sowing machinery. The device introduces seeds into a cylinder, then introduces water, and utilizes buoyancy to cause coated wheat seeds and lighter, less-full seeds to float on the water surface. Continuous water introduction allows impurities and unqualified seeds to automatically flow away along the water flow, thereby improving seed selection efficiency and preventing dust from being generated.

[0018] The second servo motor drives the hollow shaft to rotate, which can drive the stirring rod to rotate, so as to stir the seeds sunk in the water in the cylinder, thereby facilitating the floating of unfilled seeds and impurities in the seeds, thereby improving the seed selection effect;

[0019] Water can be continuously supplied to the hollow shaft through the second water supply pipe, and then the water is discharged along the holes on the stirring rod, thereby longitudinally impacting the wheat seeds, thereby further improving the stirring effect of the wheat seeds during stirring, which is conducive to further improving the effect of removing unqualified seeds from the seeds, and further improving the seed selection effect.
