[0029] The present invention is further configured as: a screening method for a seed screening device for alfalfa breeding, comprising the following screening steps: T1. Before the screening process, the device uses a sliding snap-fitting between a snap-fitting frame and a rectangular snap-fitting slot, and thereby uses external bolts to detachably connect and fix the snap-fitting frame to the device, so that the entire driving member and the screening member slidably arranged inside it are installed inside the device, so as to carry out the subsequent seed screening operation of alfalfa breeding.

[0030] After steps T2 and T1 are completed, the alfalfa breeding seeds to be screened are poured into the storage box, and then the driving motor is started to drive the several grooves opened on the top of the rotating cylinder to slide back and forth with the resistance balls, and this is combined with the elastic force of the reset spring to make the I-shaped slider move back and forth up and down between the two U-shaped vertical plates, and the connecting arm hinged between the U-shaped horizontal plate and the hinge shaft repeatedly rotates.

[0031] T3. While the connecting arm is repeatedly hinged and rotated, it pushes the T-shaped guide block that slides inside the guide transverse groove to perform reciprocating horizontal movement, so that the articulated arm that is hinged and matched between the articulated column and the articulated seat is synchronously hinged and rotated, so that the V-shaped screening plate fixed to the inner wall of the screening frame is synchronously reciprocated up and down shaken inside the equipment, so as to perform screening, shaking and flattening operations on the alfalfa breeding seeds to be screened that intermittently fall onto the upper surface of the V-shaped screening plate.

[0032] T4. The V-shaped screening plate fixed on the inner wall of the screening frame synchronously shakes up and down reciprocatingly inside the equipment, and at the same time, the V-shaped screening plate fixed on the inner wall of the screening frame reciprocates to approach or move away from a number of dredging rods fixed on the outer bottom of the V-shaped plate. Through the reciprocating approach or distance process between the V-shaped screening plate and the dredging rods, the screening holes on the V-shaped screening plate are reciprocatingly dredged and guided to avoid solid impurities in the alfalfa breeding seeds that are the same size as the screening holes and cause blockage of the screening holes on the V-shaped screening plate.

[0033] T5. The V-shaped screening plate fixed on the inner wall of the screening frame synchronously shakes up and down reciprocatingly inside the equipment, and its rotation is coordinated with the rotating arm between the first rotating column and the second rotating column to synchronously hinge and rotate reciprocatingly, thereby providing a power source for the reciprocating movement of the two rectangular sliders in the two rectangular grooves.

[0034] T6. When the two rectangular sliders move back and forth inside the two rectangular grooves respectively, the storage box fixedly connected between the two rectangular sliders synchronously slides back and forth on the top of the two supporting bottom plates fixed inside the discharge box, so that the first discharge grooves arranged at intervals through the top of the cross partition are repeatedly overlapped and separated with the second discharge grooves opened through the bottom of the storage box, thereby realizing the intermittent opening and closing process of the second discharge grooves, so that the alfalfa breeding seeds to be screened temporarily stored in the storage box intermittently fall into the screening element for subsequent screening operations.

[0035] The advantages of the present invention are as follows: 1. The present invention enables the storage box between the two rectangular sliders to synchronously slide back and forth on the top of the two supporting bottom plates fixed inside the discharge box, so that the first discharge troughs arranged at intervals and penetrating the top of the cross partition plate repeatedly overlap and separate with the second discharge troughs penetrating the bottom of the storage box, thereby realizing the intermittent opening and closing process of the second discharge troughs penetrating the bottom of the storage box, avoiding the process of discharging a large amount of materials at one time, so that the alfalfa breeding seeds to be screened are excessively accumulated inside the screening member, causing blockage to the screening structure of the screening member, thereby preventing it from affecting the subsequent screening process.

[0036] The U-shaped sliding block is fixed on the top of the two extension rods to move up and down between the two U-shaped vertical plates, and the elastic force of the return spring fixedly connected between the U-shaped sliding block and the U-shaped vertical plate makes the connecting arm hingedly matched between the U-shaped horizontal plate and the hinge shaft to repeatedly hinge and rotate, thereby promoting the T-shaped guide block slidingly matched inside the guide horizontal groove to move back and forth horizontally, so that the hinged arm hingedly matched between the hinge column and the hinge seat synchronously hinges and rotates back and forth, and finally makes the V-shaped screening plate fixed on the inner wall of the screening frame synchronously shake up and down reciprocatingly inside the equipment, so as to perform screening, shaking and flattening operations on the alfalfa breeding seeds to be screened that fall on the upper surface of the V-shaped screening plate, avoid intermittently falling too much alfalfa breeding seeds to be screened in one area, prevent them from affecting the later screening process, and improve the screening effect of alfalfa breeding seeds.

[0037] 3. When the guide holes penetrated through the top of the rectangular displacement plate of the present invention slide back and forth up and down on the peripheral side surfaces of the guide vertical rods, the V-shaped screening plate fixed on the inner wall of the screening frame reciprocates to approach or move away from the dredging rods fixed on the outer bottom of the V-shaped plates, and the screening holes on the V-shaped screening plate are reciprocatedly dredged and guided, so as to avoid the solid impurities in the alfalfa breeding seeds to be screened that are the same size as the screening holes from clogging the screening holes on the V-shaped screening plate, preventing them from affecting the subsequent screening process, thereby improving the screening efficiency and effect of the entire equipment.

[0060] The specific application of the second embodiment is as follows: when the device is in use, the clamping frame 401 is firstly slidably clamped with the rectangular clamping slot 309, and the clamping frame 401 is detachably connected and fixed to the device through external bolts, so that the entire driving member 4 and the screening member 5 slidably arranged inside the driving member 4 are installed inside the device, so as to perform the seed screening operation of alfalfa breeding in the later stage;

[0061] When the device is screening alfalfa breeding seeds, as the alfalfa breeding seeds to be screened intermittently enter the upper surface of the V-shaped screening plate 509 fixed to the inner wall of the screening frame 501 from the storage structure, the drive motor 414 is synchronously started to drive the rotating cylinder 415 fixed to the output shaft of the drive motor 414 to rotate synchronously, so that the grooves 417 opened on the top of the rotating cylinder 415 reciprocate and slide in contact with the contact balls 413, driving the side surfaces of the two contact balls 413 to rotate.

[0062] When the guide holes 511 penetrated through the top of the rectangular displacement plate 502 slide back and forth up and down on the peripheral side of the guide vertical rod 403, the V-shaped screening plate 509 fixed on the inner wall of the screening frame 501 reciprocates to approach or move away from the dredging rods 313 fixed on the outer bottom of the V-shaped plates 312, so that the screening holes on the V-shaped screening plate 509 are reciprocatedly dredged and guided through the reciprocating approach or distance process between the V-shaped screening plate 509 and the dredging rods 313, so as to avoid the solid impurities in the alfalfa breeding seeds to be screened that are the same size as the screening holes from clogging the screening holes on the V-shaped screening plate 509, preventing it from affecting the later screening process, thereby improving the screening efficiency and effect of the entire equipment;

The entire process does not require the addition of an additional power source, and the intermittent discharging and screening process during the operation of the entire equipment can be achieved by using the same power source.

[0064] Embodiment three, a screening method for a seed screening device for alfalfa breeding, comprises the following screening steps: T1, before the screening process of the device, the sliding snap-fitting between the snap-fitting frame 401 and the rectangular snap-fitting slot 309 is used, and the snap-fitting frame 401 is detachably connected and fixed to the device by external bolts, so that the entire driving member 4 and the screening member 5 slidingly arranged inside it are installed inside the device, so as to carry out the subsequent seed screening operation of alfalfa breeding.

[0065] After steps T2 and T1 are completed, the alfalfa breeding seeds to be screened are poured into the storage box 201, and then the drive motor 414 is started to drive the plurality of grooves 417 opened on the outer top of the rotating cylinder 415 to slide back and forth with the resistance ball 413, and this, combined with the elastic force of the reset spring 410, causes the I-shaped slider 409 to move up and down reciprocatingly between the two U-shaped vertical plates 408, and the connecting arm 607 hingedly matched between the U-shaped horizontal plate 606 and the hinge shaft 416 repeatedly hinges and rotates.
