Description

Technical Field

[0001] The utility model relates to the field of rice seed screening, in particular to a seed screening device. Background Art

[0002] There are impurities and bad seeds in rice seeds, so they need to be screened. Screening can ensure the quality of rice seeds, improve germination rate and growth potential, and thus increase yield and quality. Secondly, through screening, growers can choose suitable varieties according to the environment and needs, achieve scientific planting, and improve efficiency. In addition, screening can also help reduce the risk of pests and diseases, enhance the ability to resist pests and diseases, and reduce the risk of agricultural production.

[0003] A Chinese patent with authorization announcement number CN218591129U discloses a rice seed screening device. When the rice seed screening device is in use, at the time when the rice seeds fall from the adjustment plate to the inside of the stirring pool, the second motor inside the synchronized second rotating shaft gives the fan appropriate wind force, so that the lighter and deflated rice seeds inside the rice seeds are offset under the action of the wind, and then blown to the inside of the gauze, and fall into the collection box under the action of gravity. Further, other rice seeds fall into the inside of the stirring pool, and then through the stirring of the stirring pool, other hollow seeds inside are made to float to the surface, thereby achieving the effect of cleaning impurities and deflated rice seeds.

[0004] However, the above-mentioned disclosed solution has the following shortcomings: although the device can clean lighter and deflated rice seeds and hollow seeds, it is not easy to clean stones mixed in the rice seeds. The stones in the rice seeds will not be offset under the action of wind. At the same time, due to the large specific gravity of the stones, they will not float on the water surface and are not easy to clean. Utility Model Content

A material placing plate 342 is provided at the bottom end of the connecting rod 341. The material placing plate 342 is in the shape of an inwardly concave arc plate. The rice seeds are placed in it and are not easy to spill out. They are also easy to throw out when rotating.

[0049] Embodiment 4

[0050] like Figure 1-Figure 4 As shown, the seed screening device proposed by the present invention further discloses the specific structure of the collecting component 4 compared with the first embodiment.

[0051] The collecting plate 41 is arranged outside the rotating rod 211. The number of the collecting plates 41 is set to four. The four collecting plates 41 are arranged to be spirally arranged around the central axis of the rotating rod 211. The bottom ends of the four collecting plates 41 are in contact with the inner bottom surface of the tank body 1.

[0052] The pull-out box 42 is arranged on the bottom surface of the tank body 1.

[0053] Embodiment 5

[0054] like Figure 1-Figure 4 As shown, the seed screening device proposed by the present invention further discloses the specific structure of the limiting component 5 compared with the first embodiment.

[0055] The limiting shaft 51 is arranged at the center of the upper end surface of the conical cylinder b33, and a clamping groove is provided on the outer side of the limiting shaft 51;

[0056] The limiting rod 52 is rotatably arranged on the tank body 1 , and an arc-shaped clamping plate 521 is arranged at one end of the limiting rod 52 , and the shape of the arc-shaped clamping plate 521 fits the clamping groove.

[0057] Embodiment 6

[0058] like Figure 1-Figure 4 As shown, the utility model proposes a seed screening device. Compared with the first embodiment, this embodiment further specifically discloses the specific structure of the water inlet pipe 6 and the drainage pipe 7.

[0059] A water inlet pipe 6 for inputting water source is arranged outside the tank body 1. Water source is input through the water inlet pipe 6 to fill the tank body 1 and overflow the screening component 3.

[0060] Furthermore, a screen is provided in the connection end between the water inlet pipe 6 and the tank body 1 , and the apertures of the screen are smaller than the leakage hole a311 , the leakage hole b331 and the de-screening hole 321 .

[0061] A drain pipe 7 for discharging waste water is arranged outside the tank body 1. The waste water in the tank body 1 is immediately discharged through the drain pipe 7 after the driving is stopped.

[0062] In summary, the working principle of the utility model is as follows: first, open the cover body 34 and place the rice seeds on the placing plate 342, then close the cover body 34, and then start the motor 21. The motor 21 drives the rotating rod 211 to rotate, and the rotating rod 211 drives the plug-in rod 22 to rotate. The plug-in rod 22 drives the entire screening component 3 to rotate. At the same time, clean water is injected through the water inlet pipe 6 to fill the tank body 1 and overflow the screening component 3. In addition, the limiting rod 52 is rotated to clamp the arc-shaped clamping plates 521 on the two limiting rods 52 to the limiting shaft 51 on the cover body 34, and the two arc-shaped clamping plates 521 are fixed to prevent the screening component 3 from being thrown out when rotating. The motor 21 drives the screening component 3 to rotate. Under the action of centrifugal force, materials with different specific gravities will have different motion trajectories, thereby achieving separation. Specifically, materials with higher specific gravity will move in the direction of the largest rotor radius, while materials with lighter specific gravity will move above materials with heavier specific gravity, forming different layers, thereby achieving separation. Purpose, applied to the present device, the rotation radius of the conical cylinder a31 is larger than that of the middle cylinder 32 and the conical cylinder b33, and because of the specific gravity of the stone, the centrifugal force can throw the stone downward from the leakage hole a311 of the conical cylinder a31, and the bad seeds with lighter specific gravity will be thrown upward from the leakage hole b331 in the conical cylinder b33 whose rotation radius is smaller than that of the conical cylinder a31 and larger than that of the middle cylinder 32 through the buoyancy of water, and some fine impurities in the rice seeds can be thrown out through the leakage hole b331 in the middle cylinder 32. The rice seeds are discharged through the sieve hole 321. After screening, the driving is stopped. The stones and bad seeds in the rice seeds have been thrown out of the screening component 3 during rotation, and the intact and full rice seeds fall on the inner bottom of the conical cylinder a31. Take out the screening component 3, open the cover 34, and pour them out. While the stones are rotating, the motor 21 simultaneously drives multiple collecting plates 41 to rotate, sweeping the stones into the pull-out box 42, which is cleaned after it is full. The wastewater in the tank body 1 is immediately discharged by starting the drain pipe 7 after the driving is stopped.

[0063] The implementation modes of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
