DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] like Figure 1As shown, the utility model provides a screening device for radish seed selection, comprising a screening box 1, a hopper 2 is fixedly embedded in the middle of the top surface of the screening box 1, and the hopper 2 is used to introduce radish seeds into the screening box 1 for screening.

[0023] like Figures 1 to 3 As shown, in this embodiment, a discharging assembly is provided on the screening box 1 for discharging radish seeds, a curved pipe 3 is rotatably installed at the bottom of the feed hopper 2, and the curved pipe 3 can rotate horizontally along the bottom of the feed hopper 2 for guiding and transporting radish seeds, and an arc-shaped fixing plate 4 horizontally fixedly connected to the inner wall of the screening box 1 is provided below the curved pipe 3, and a driven gear 11 is fixedly sleeved on the outer top of the curved pipe 3;

[0024] Four partitions 5 are equidistantly installed in a circular manner on the top surface of the arc-shaped fixed plate 4, and the heads of the partitions 5 are connected and the tails are respectively connected to the inner wall of the screening box 1, and the screening slots 6 are formed between two adjacent partitions 5 and the top surface of the arc-shaped fixed plate 4. The four partitions 5 cooperate with the arc-shaped fixed plate 4 to form four screening slots 6, so as to facilitate screening of different types of radish seeds. A plurality of screening holes 7 are provided at the bottom of the inner side of the screening slot 6, and the screening holes 7 in each screening slot 6 form a group. The inner diameter of each group of screening holes 7 gradually increases clockwise, so as to facilitate screening of different types of radish seeds through screening holes 7 of different sizes;

[0025] A plurality of deceleration columns 17 are vertically installed in the screening slot 6 and are offset from the screening holes 7. The deceleration columns 17 block the radish seeds, reduce the speed at which the radish seeds roll on the arc-shaped fixed plate 4, and prevent the smaller radish seeds from rolling quickly and affecting the screening quality.

[0026] A mutually meshing driving gear 12 is disposed outside the driven gear 11, and the inner ring of the driving gear 12 is connected to the output shaft of the motor 13 which is locked and fixed at the top of the screening box 1;

[0027] In this embodiment, a vibration motor 16 is installed on the bottom end surface of the arc-shaped fixed plate 4, and the vibration motor 16 drives the arc-shaped fixed plate 4 to vibrate, so as to improve the screening efficiency of the radish seeds;

[0028] In this embodiment, the inner wall of the curved tube 3 is flush with the inner bottom of the hopper 2, and the bottom end surface of the curved tube 3 is higher than the top surface of the partition 5 and the deceleration column 17, so that the radish seeds in the hopper 2 can stably enter the curved tube 3;

[0029] In this embodiment, a transparent plate 10 is fixedly embedded in the upper end of the screening box 1, and the transparent plate 10 is directly opposite to the curved pipe 3, so that the position of the curved pipe 3 can be observed through the transparent plate 10;

[0030] When in use, the radish seeds are introduced into the hopper 2, and the radish seeds roll into the curved tube 3 through the hopper 2, and the radish seeds fall downward from the curved tube 3 into the screening slot 6, and the vibration motor 16 is started to drive the arc-shaped fixing plate 4 to vibrate, and the arc-shaped fixing plate 4 drives the radish seeds to vibrate, so that the radish seeds are quickly screened in the screening slot 6, and the smaller radish seeds pass through the screening holes 7 and fall downward to be discharged from the bottom of the screening box 1, while the radish seeds with larger particle sizes remain in the screening slot 6. Since the arc-shaped fixing plate 6 is an arc plate, the inner bottom of the screening slot 6 is also arc-shaped, so that the radish seeds in the screening slot 6 roll outward to the edge of the screening slot 6;

[0031] When screening different kinds of radish seeds, the driving gear 12 can be driven to rotate by controlling the motor 13, and the driving gear 12 cooperates with the driven gear 11 to drive the curved tube 3 to rotate, so that the bottom of the curved tube 3 is aligned with different screening slots 6 after rotation, and the sizes of the screening holes 7 in different screening slots 6 are different, so that different kinds of radish seeds can be screened through the screening holes 7 of different sizes, thereby improving the flexibility of the screening device.

[0032] like Figure 3 As shown, in this embodiment, the discharge assembly includes a plurality of discharge ports 8 and a plurality of baffles 9. The discharge ports 8 are provided on the screening box 1 and correspond one-to-one with the screening slots 6, so that the radish seeds in the screening slots 6 can be discharged outward through the discharge ports 8. The baffles 9 are movably mounted on the screening box 1 and correspond one-to-one with the discharge ports 8. The baffles 9 completely cover the inner side of the discharge ports 8, so that the discharge ports 8 can be sealed by the baffles 9, thereby reducing the discharge of smaller radish seeds through the discharge ports 8 before being screened.

[0033] In this embodiment, one end of the baffle 9 is hinged to the side surface of the screening box 1 through a hinge 14, so that the baffle 9 can be rotated to open the discharge port 8;

[0034] In this embodiment, the end of the baffle 9 away from the hinge 14 is locked and fixed to the screening box 1 by a butterfly bolt 15, so that the position of the baffle 9 can be fixed by the butterfly bolt 15 to prevent the baffle 9 from rotating at will;

[0035] When in use, the screening box 1 can be detached by rotating the butterfly bolt 15, and then the baffle 9 is pulled to open the discharge port 8, and then the radish seeds with larger particle sizes in the screening slot 6 are discharged outward through the discharge port 8. After the radish seeds are discharged, the baffle 9 is rotated again to seal the discharge port 8, and the butterfly bolt 15 is rotated in the opposite direction to connect the screening box 1, so as to fix the position of the baffle 9, so as to facilitate the screening of the next batch of radish seeds.

[0036] The above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
