Description

Technical Field

[0001] The utility model relates to the field of agricultural devices, in particular to a seed screening device used for agricultural planting. Background Art

[0002] Seeds are the chips of agriculture. Seeds contain all the genetic information for crop growth. By cultivating high-quality seeds, crops can have more excellent traits, such as high yield, stable yield, disease resistance, insect resistance, etc., thereby improving agricultural production efficiency and output. Before agricultural planting, breeding and seed selection are indispensable links. Existing seed screening methods are mostly wind selection or water selection. Most of the existing water selection equipment introduces seeds into a container filled with water. Bad seeds and seed coat magazines will float. The floating objects are fished out and then the seeds are fished out to achieve water-seed separation. Each time, it is necessary to fish out the floating objects first and then the seeds. Repeat the above operation to continuously water-select seeds. The seed water selection has poor sustainability and low efficiency. Utility Model Content

[0014] The utility model is further described below in conjunction with the accompanying drawings:

[0015] like Figure 1 As shown, a seed screening device for agricultural planting is composed of a water selection tank body 1 and a mesh cover body 2;

[0016] The mesh cover 2 is installed on the top of the water selection tank 1, and a auger 3 is rotatably installed in the middle of the mesh cover 2. A funnel-shaped hole set 4 is installed on the top of the mesh cover 2 through a bucket fixing frame 9. The funnel-shaped hole set 4 is used to temporarily store and gather seeds after water selection. Water and small particle sediments are discharged and fall through the seepage holes of the funnel-shaped hole set 4. A power box 11 is installed on the top of the funnel-shaped hole set 4.

[0017] The top of the auger barrel 3 extends into the power box 11 and is installed with a barrel cap 13. A feeding shaft 25 is rotatably installed in the middle of the barrel cap 13. The top of the feeding shaft 25 extends to the top of the barrel cap 13 and is fixedly installed with a shaft gear 14. A barrel sleeve gear 12 is fixedly mounted on the auger barrel 3 in the power box 11. The bottom funnel mouth of the funnel-shaped hole set 4 matches the outer barrel diameter of the auger barrel 3, which is convenient for the auger barrel 3 to pass through. A small gap is left between them to facilitate the rotation of the auger barrel 3.

[0018] A motor 19 is installed in the power box 11, and the motor 19 is connected to the first motor gear 16 and the second motor gear 18 through the motor gear shaft 17. The second motor gear 18 is meshed and connected with the sleeve gear 12. The first motor gear 16 is meshed and connected to the shaft gear 14 through the intermediate gear 15, wherein the intermediate gear 15 is rotatably installed on the top of the power box 11 through the intermediate gear shaft, and serves as an intermediate transmission gear, so that the shaft gear 14 drives the feeding shaft 25 to rotate in the opposite direction to the rotation direction of the auger barrel 3;

[0019] The bottom end of the auger 3 extends to the interior of the water selection tank 1 and is installed with an underwater stirring rod 6, which is used to stir the agricultural seeds that need to be screened to facilitate the floating of bad seeds and seed coats. A controller 22 is installed on the outside of the water selection tank 1.

[0020] like Figure 1 As shown, the utility model also discloses the following more optimized specific structures:

[0021] A water inlet pipe 7 is installed on the outer top of the water selection tank body 1, and a control valve is installed on the water inlet pipe 7. A drainage hole is provided at the bottom of the water selection tank body 1, and a bottom drain valve 24 is installed on the drainage hole. A tank bracket 23 is installed on the bottom support of the water selection tank body 1, and a water level sensor 21 is installed on the inner side of the water selection tank body 1.

[0022] A sweeping roller 10 is installed on the auger barrel 3 in the funnel-shaped hole set 4, and a discharge installation hole is opened on the funnel-shaped hole set 4. An inclined discharge bucket 5 is installed on the discharge installation hole to facilitate the discharge of seeds after water selection.

[0023] The auger barrel 3 in the funnel-shaped hole kit 4 is provided with barrel row holes, which facilitates the introduction of seeds transported upward into the funnel-shaped hole kit 4. The feeding shaft 25 in the auger barrel 3 is equipped with a stirring roller 20 and a feeding auger 26, and the stirring roller 20 is arranged at the barrel row holes.

[0024] A seed introduction port is provided on the mesh cover body 2, and a feed hopper 8 is installed on the seed introduction port.

[0025] like Figure 1The seed screening device for agricultural planting shown is mainly used for screening agricultural seeds. The seeds of crops such as wheat or corn are water-screened by setting different mesh sizes. Water is introduced into the water screening tank 1 through the water inlet pipe 7 to reach the specified water level. The water level monitoring is mainly achieved through the water level sensor 21. The seeds to be screened are introduced into the water screening tank 1 through the feed hopper 8. The full seeds sink, and the seed coats and unfull seeds float. The sunken seeds are transported upward by the feeding auger 26. When they reach the cylinder row holes, they enter the funnel-shaped hole kit 4 and are swept into the inclined row bucket 5 by the sweeping roller 10. During the sweeping process, due to the setting of the seepage holes, excess water can seep out and flow back, and the auger cylinder 3 and the feeding shaft 25 rotate in opposite directions, and the underwater seeds can be stirred by the underwater stirring rod 6 to improve the water selection efficiency and the feeding efficiency. The seeds are continuously introduced inward, and water selection and feeding are carried out while the seeds are introduced. When the water needs to be replaced, the screened mixed water is discharged through the bottom discharge valve 24.

The above-mentioned embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
