The top and opposite sides of both sets of collection boxes are designed to be open, and interception nets are fixed at the bottom and side walls of the collection boxes.

[0007] A further improvement is that the translation drive mechanism includes a bidirectional lead screw rotatably connected inside the screening box and driven to rotate by a first motor, and threaded plates threadedly sleeved on both sides of the bidirectional lead screw, with the bottom end of the threaded plates fixed to the top of the collection box.

[0008] A further improvement is that a shielding cover fixed on the bidirectional screw is fixed inside the screening box, and the outer walls of the front and rear sides of the collection box are slidably attached to the inner walls of the front and rear sides of the screening box, respectively.

[0009] A further improvement is that the stirring mechanism includes a stirring shaft rotatably connected inside the screening box and driven to rotate by a second motor, and stirring rods symmetrically fixed on the stirring shaft, with stirring blades fixed at the end of the stirring rods away from the stirring shaft.

[0010] A further improvement is that: the inner wall of the collection box is symmetrically fixed with support blocks located below the filter frame, and the top of the filter frame is symmetrically fixed with pull rings.

[0011] A further improvement is that: the lower part of both sides of the collection box is fixed with a water outlet pipe with a built-in control valve, and a control valve is installed on the drain outlet.

[0012] A further improvement is that: the bottom of the screening box is symmetrically fixed with support columns, the bottom of the support columns is fixed to the top of the base, and the bottom of the base is symmetrically fixed with casters.

[0020] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0021] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, this embodiment provides a corn seed detection and screening device that facilitates collection. It includes a screening box 1 with an open top and a drain outlet 2 fixed to the bottom of the screening box 1. The bottom of the screening box 1 has a funnel-shaped conical design. A horizontally positioned base 3 is fixed below the screening box 1. A collection box 4 with an open top is placed on the top of the base 3. A filter frame 5 is fitted inside the collection box 4. A seed interception net for intercepting corn seeds in the water is fixed to the bottom of the filter frame 5. The screening box 1 has a stirring mechanism inside for agitating the water used for screening corn seeds. Collection boxes 6 are located on the left and right sides of the upper part of the screening box 1, and the two sets of collection boxes 6 are driven by a translational drive mechanism. The two sets of collection boxes 6 are designed with open tops and opposite sides for easy splicing. The bottom and side walls of the collection boxes 6 are fixed with interception nets to facilitate water passage. By embedding a filter frame 5 in the collection box 4 below the drain outlet 2 and fixing a seed interception net at the bottom of the filter frame 5, qualified corn seeds can be intercepted, thus automatically intercepting and collecting corn seeds that sink in the water. The two sets of collection boxes 6 are driven to move towards each other and merge through a translation drive mechanism to scoop up unqualified corn seeds floating on the water surface into the collection box 6, thereby automatically collecting unqualified corn seeds floating on the water surface.

[0022] The translation drive mechanism includes a first motor 7, a bidirectional lead screw 8, and a threaded plate 9. The first motor 7 is fixed to the outer left wall of the screening box 1 by bolts. The bidirectional lead screw 8 is rotatably connected to the inside of the screening box 1 through bearings and is driven to rotate by the first motor 7. There are two sets of threaded plates 9, which are threaded onto both sides of the bidirectional lead screw 8 with opposite threading directions. The bottom end of the threaded plate 9 is fixed to the top of the collection box 6, which serves to suspend and fix the collection box 6. The length of the threaded plate 9 ensures that the bidirectional lead screw 8 is away from the water surface while the collection box 6 is in contact with water, thus preventing water from contacting the bidirectional lead screw 8 and affecting its normal transmission. A shield 10 is fixed inside the upper part of the screening box 1 and covers the bidirectional lead screw 8, which provides a certain degree of protection for the bidirectional lead screw 8 and prevents the corn seeds from contacting the bidirectional lead screw 8 when added. The outer walls of the front and rear sides of the collection box 6 slide against the inner walls of the front and rear sides of the screening box 1, which limits the movement of the collection box 6 and makes it more stable during movement.

[0023] The stirring mechanism includes a second motor 11, a stirring shaft 12, and a stirring rod 13. The second motor 11 is fixed to the outer left side of the screening box 1 by bolts. The stirring shaft 12 is rotatably connected to the inside of the screening box 1 through bearings and is driven to rotate by the second motor 11. The stirring rod 13 is symmetrically fixed on the stirring shaft 12. A stirring blade 14 is fixed to the end of the stirring rod 13 away from the stirring shaft 12. The stirring shaft 12 is driven to rotate by the second motor 11, and the stirring shaft 12 then drives the stirring blade 14 to rotate through the stirring rod 13, thereby agitating the water.

[0024] Support blocks 15 are symmetrically fixed to the inner wall of the collection box 4, and the support blocks 15 are located below the filter frame 5 to support the filter frame 5. Pull rings 16 are symmetrically fixed to the top of the filter frame 5 to facilitate the user to lift the filter frame 5. The lower part of the left and right side walls of the collection box 4 are fixed with water outlet pipes 17 with built-in control valves to facilitate drainage. A control valve is installed on the drain outlet 2 to facilitate drainage control.

[0025] The bottom of the screening box 1 is symmetrically fixed with support columns 18, and the bottom of the support columns 18 is fixed to the top of the base 3 to provide stable support for the screening box 1. The four corners of the bottom of the base 3 are all fixed with casters by bolts to make the equipment easy to move.

[0026] When screening corn seeds for quality testing, first fill the screening box 1 with water until the water level reaches the middle of the collection box 6. Then, pour the corn seeds to be screened into the screening box 1, allowing them to fall into the water. Simultaneously, use the stirring mechanism to agitate the water in the screening box 1, causing the corn seeds to tumble and disperse. Shriveled corn seeds will float to the surface, indicating they are substandard. Then, stop agitating the water in the screening box 1, and the qualified corn seeds will continue to fall until they reach the screening box. The drain outlet 2 is located at the bottom of the screening box 1. Then, the translation drive mechanism drives the two sets of collection boxes 6 to move towards each other and merge, so as to scoop up the substandard corn seeds floating on the water surface and put them into the collection box 6, realizing the automatic collection of substandard corn seeds. After that, the control valve on the drain outlet 2 is opened to drain the water in the screening box 1, and the qualified corn seeds are discharged into the collection box 4 with the water and intercepted in the seed interception net at the bottom of the filter frame 5. Then, the filter frame 5 and the seed interception net are removed from the collection box 4, thus completing the quality detection and screening of corn seeds.
