AI Technical Summary
Traditional crop seed screening equipment involves cumbersome screen replacement, resulting in high operational complexity and time costs, making it difficult to meet the needs of modern agriculture for efficient screening.
Design a screening device for superior crop seeds. It adopts a movable frame and a screen winding assembly. By rotating the screen winding assembly, the device can quickly switch between screens with different mesh sizes, avoiding disassembly of the equipment. The screening is carried out using a screen body composed of a base fabric, a first screen, a second screen, and a third screen.
It significantly improves the efficiency of screen replacement, reduces operational complexity and time costs, adapts to the screening needs of different crop seeds, and provides an efficient and convenient solution for agricultural production.

A good seed screening device for agricultural crops, comprising a device support (1), a movable frame (2) movably mounted on the device support (1), characterized in that: Four mounting brackets (3) are symmetrically fixed at both ends of the movable frame (2). Two screen winding assemblies (4) are rotatably mounted on the four mounting brackets (3). Each screen winding assembly (4) consists of a winding shaft (12), a mounting plate (13), and a handle (14). There are two mounting plates (13) and they are fixedly mounted at both ends of the winding shaft (12). There are two handles (14) and they are fixedly mounted at one end of each of the two mounting plates (13). The two handles on the two screen winding assemblies (4) are... A screen body (19) is fixedly wound on the reel (12). The screen body (19) passes through the movable frame (2) at the same time. The screen body (19) is composed of a base fabric (15), a first screen (16), a second screen (17) and a third screen (18). The first screen (16), the second screen (17) and the third screen (18) are fixedly embedded in the base fabric (15) in sequence. The mesh diameters of the first screen (16), the second screen (17) and the third screen (18) are different.
2. A crop elite seed screening apparatus as claimed in claim 1, wherein: A drive device (5) is fixedly installed on the equipment bracket (1), and a support pulley (6) and a guide plate (7) are also fixedly installed on the equipment bracket (1).
3. A crop elite seed screening apparatus as claimed in claim 2, wherein: The movable frame (2) consists of a frame body (8) and baffles (9). There are two baffles (9) that are symmetrically fixed on the inner wall of the frame body (8). The frame body (8) is slidably mounted on the support pulley (6) and is also connected to the drive device (5). The frame body (8) is located above the guide plate (7). Two screen grooves (10) are symmetrically opened on the two side walls of the frame body (8) and below the two baffles (9).
4. A crop elite seed screening apparatus as claimed in claim 3, wherein: The mounting bracket (3) is fixedly installed on the frame body (8), and the mounting bracket (3) has a shaft hole (11).
5. A crop elite seed screening apparatus as claimed in claim 4, wherein: The winding shaft (12) on the screen winding assembly (4) is rotatably installed in two shaft holes (11) on two mounting brackets (3), and the mounting plate (13) and handle (14) are both located on the outside of the mounting brackets (3).
6. A crop elite seed screening apparatus as claimed in claim 5, wherein: The screen body (19) passes through two screen slots (10) opened on the frame body (8), and the base fabric (15) is fixedly connected to two winding shafts (12).
