Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment

[0031] Such as Figure 1 , Figure 2 , Figure 3 AndFigure 4 As shown in the figure, the present utility model provides a technical solution: a seed screening device, including a support base 1, a base 2 is installed at the bottom end of the support base 1, fixing seats 3 are arranged at the front and rear ends of the support base 1, and a screening component 4 is installed in the middle of the fixing seat 3;

[0032] The screening component 4 includes a rotating motor 401, a first transmission belt 402, a double-groove pulley 403, a second transmission belt 404, a rotating shaft 405 and a rotating frame 406. The rotating motor 401 is installed in the middle of the fixing seat 3, and the output end of the rotating motor 401 is sleeved with the first transmission belt 402. The other end of the first transmission belt 402 is installed with the double-groove pulley 403, and the rear end of the double-groove pulley 403 is sleeved with the second transmission belt 404. The upper end of the second transmission belt 404 is installed with the rotating shaft 405, and the rotating frame 406 is arranged on the outer surface of the rotating shaft 405;

[0033] An inner groove holder 5 is provided in the middle of the screening component 4; on both sides of the middle ends of the support base 1 and the base 2, there are material receiving boxes 7. Specifically, first, the bottom end of the support base 1 is connected to the base 2, and the rotating motor 401 of the screening component 4 can be supported by the fixing base 3. The first transmission belt 402 is sleeved in the front groove of the output end of the rotating motor 401 and the double-groove pulley 403, and then the second transmission belt 404 is sleeved in the rear groove of the rotating shaft 405 and the double-groove pulley 403 for installation. By turning on the rotating motor 401, the first transmission belt 402 and the second transmission belt 404 are driven to rotate simultaneously, effectively driving the rotating frame 406 with two groups of rotating shafts 405 sleeved inside the second transmission belt 404 to rotate. It is a friction-type belt drive with frictional force transmission between the double-groove pulley 403 and the rotating shaft 405, and a synchronous belt drive relying on the teeth on the wheels of the first transmission belt 402, the second transmission belt 404, the double-groove pulley 403, and the rotating shaft 405 to mesh and drive each other. Since an inner groove holder 5 is provided in the middle of the rotating frame 406, it is convenient for the user to install the inner groove holder 5 in the screening frame 601 of the placement component 6. The seeds to be screened are put into the screening frame 601, and the screening frame 601 is inserted into the inner groove holder 5 for installation. By using the clamping cover 602 to be clamped in the front slot of the screening frame 601, the screening frame 601 can be sealed. By passing the bolt 603 through the middle of the clamping cover 602 and the rotating frame 406, the screening frame 601 can be locked in the rotating frame 406 for installation, preventing the screening frame 601 from falling during rotation. During the rotation of the screening frame 601, the centrifugal force generated can make the seeds inside the screening frame 601 rotate and fall into the material receiving box 7 for collection. The rotating motor 401 drives the screening frame 601 at a relatively slow speed, so that the seeds rotated and brushed off inside the screening frame 601 can all accumulate in the material receiving box 7 for collection. Through this technical solution, the problems that the screening space is small and it is not convenient to quickly screen the seeds during screening are solved, and it is realized that the bottom end of the support base 1 is connected to the base 2, the rotating motor 401 of the screening component 4 can be supported by the fixing base 3, the first transmission belt 402 is sleeved in the front groove of the output end of the rotating motor 401 and the double-groove pulley 403, and then the second transmission belt 404 is sleeved in the rear groove of the rotating shaft 405 and the double-groove pulley 403 for installation. By turning on the rotating motor 401, the first transmission belt 402 and the second transmission belt 404 are driven to rotate simultaneously, effectively driving the rotating frame 406 with two groups of rotating shafts 405 sleeved inside the second transmission belt 404 to rotate. It is a friction-type belt drive with frictional force transmission between the double-groove pulley 403 and the rotating shaft 405, and a synchronous belt drive relying on the teeth on the wheels of the first transmission belt 402, the second transmission belt 404, the double-groove pulley 403, and the rotating shaft 405 to mesh and drive each other.

[0034] Furthermore, as Figure 1As shown in the figure: There is also a material collection box 7 arranged on both sides of the middle ends of the support base 1 and the base 2. The advantage of this technical solution is that during the rotation of the screening box 601, the centrifugal force generated can rotate and drop the seeds inside the screening box 601 into the material collection box 7 for collection. The rotation motor 401 drives the screening box 601 at a relatively slow speed, so that the seeds rotated and brushed off inside the screening box 601 can all accumulate in the material collection box 7 for collection.

[0035] In the above solution, there is also a problem that it is not convenient to place the seeds, such as Figures 1-4 As shown in the figure: In this solution, the placement component 6 includes a screening box 601, a clamping cover 602, and bolts 603. And the placement component 6 is inserted in the middle of the inner groove frame 5. The screening box 601 is inserted in the middle of the inner groove frame 5, and the clamping cover 602 is clamped on the outer wall of the screening box 601. Bolts 603 are inserted through both sides of the clamping cover 602. An inner groove frame 5 is provided in the middle of the rotating frame 406, which is convenient for the user to install the inner groove frame 5 in the screening box 601 of the placement component 6. The seeds to be screened are put into the screening box 601. The screening box 601 is inserted into the inner groove frame 5 for installation. By using the clamping cover 602 to be clamped in the front slot of the screening box 601, the screening box 601 can be sealed. By inserting the bolts 603 through the middle of the clamping cover 602 and the rotating frame 406, the screening box 601 can be locked in the rotating frame 406 for installation, avoiding the situation of the screening box 601 falling during rotation.

[0038] First, a base 2 is connected to the bottom end of the support base 1. The rotating motor 401 of the screening component 4 can be supported by the fixing base 3. The first transmission belt 402 is sleeved in the front slot of the output end of the rotating motor 401 and the double-groove pulley 403. Then, the second transmission belt 404 is sleeved in the rear slot of the rotating shaft 405 and the double-groove pulley 403 for installation. By starting the rotating motor 401, the first transmission belt 402 and the second transmission belt 404 are driven to rotate simultaneously, effectively driving the rotating frame 406 with two groups of rotating shafts 405 sleeved inside the second transmission belt 404 to rotate. It is a friction-type belt drive with frictional transmission between the double-groove pulley 403 and the rotating shaft 405, and a synchronous belt drive with the teeth on the wheels of the first transmission belt 402, the second transmission belt 404, the double-groove pulley 403 and the rotating shaft 405 meshing with each other. An inner groove frame 5 is provided in the middle of the rotating frame 406, which is convenient for the user to install the inner groove frame 5 in the screening frame 601 of the placement component 6. The seeds to be screened are put into the screening frame 601, and the screening frame 601 is inserted into the inner groove frame 5 for installation. The screening frame 601 can be sealed by using the cover 602 to fit into the front slot of the screening frame 601. By passing the bolt 603 through the middle of the cover 602 and the rotating frame 406, the screening frame 601 can be locked in the rotating frame 406 for installation, preventing the screening frame 601 from falling during rotation. During the rotation of the screening frame 601, the centrifugal force generated can cause the seeds inside the screening frame 601 to rotate and fall into the receiving box 7 for collection. The rotating speed of the screening frame 601 driven by the rotating motor 401 is relatively slow, so that all the seeds brushed off and rotated inside the screening frame 601 can accumulate in the receiving box 7 for collection.
