The size of the through channel can be adapted to the size of the screening rod 402, and the cross-sectional size of the push plate 401 can also be adapted to the size of the through channel, so that even if the push plate 401 and the screening rod 402 reciprocate in the vertical direction, several grafting clips 701 in the hopper 201 cannot fall out of the through channel.
[0026] In some implementations of this embodiment, a guide rod 404 is provided at one end of the screening rod 402 close to the first guide rail 403, a second slide groove extending in the vertical direction is opened in the first guide rail 403, and the guide rod 404 is slidably connected to the second slide groove; a limiting block 405 is provided at the top of the first guide rail 403.
[0027] In this embodiment, the specific connection method between the screening rod 402 and the push plate 401 is: a first slider (not shown in the figure) is hinged on the push plate 401, and a third slide groove (not shown in the figure) is opened on the screening rod 402. The extension direction of the third slide groove is the same as the extension direction of the screening rod 402, and the first slider can slide back and forth in the third slide groove.
[0028] In order to facilitate the guidance of the push plate 401, a second guide rail 406 is vertically installed on the frame 101. The second guide rail 406 extends into the hopper 201 through a through channel; the push plate 401 is slidably connected to the second guide rail 406.
[0029] Specifically, the driving mechanism includes a steering gear 501 disposed on the frame 101, a rotating shaft (not shown in the figure) drivingly connected to the execution end of the steering gear 501, and a swing arm 502 fixedly connected to the rotating shaft; the end of the swing arm 502 away from the rotating shaft is connected to the push plate 401 through a sliding connection mechanism. The sliding connection mechanism includes a second slider 601, a fourth slide groove 602 is provided at the end of the swing arm 502 away from the rotating shaft, and the extension direction of the fourth slide groove 602 is the same as the extension direction of the swing arm 502, the second slider 601 is slidably disposed in the fourth slide groove 602, and the protrusion of the second slider 601 is connected to the push plate 401. The sliding connection mechanism is designed at one end of the swing arm 502, so that the steering gear 501 can control the push plate 401 to reciprocate on the second guide rail 406. During the rotation of the swing arm 502, the position of the second slider 601 in the fourth slide groove 602 will change.
[0030] In order to facilitate the servo 501 to better control the reciprocating movement of the push plate 401 in the vertical direction, the number of swing arms 502 is specially designed to be two, and the two swing arms 502 are respectively located on both sides of the push plate 401, and the extension direction of the two swing arms 502 is the same; one end of any swing arm 502 is fixedly connected to the rotating shaft, and the end of any swing arm 502 away from the rotating shaft is connected to the push plate 401 through a sliding connection mechanism.
[0031] Working principle:
[0032] Before screening, a number of grafting clips 701 are placed in the hopper 201. Figure 3 and Figure 4 The initial position of the screening rod 402 is shown in FIG.
[0033] When screening, start the servo 501, from Figure 4From the perspective of the steering gear 501, the shaft rotates, and the rotation of the shaft first drives the two swing arms 502 to rotate counterclockwise around the central axis of the shaft. As the swing arms 502 rotate, the position of the second slider 601 in the fourth slide slot 602 changes, and the push plate 401 moves upward under the action of the swing arms 502 and the sliding connection mechanism, and the screening rod 402 also moves upward under the push of the push plate 401. Figure 5 As shown, the grafting clamp 701 will "fall" on the sieve rod 402 during the upward movement of the sieve rod 402. When the sieve rod 402 moves upward to a certain distance, the guide rod 404 will abut against the limit block 405. After the guide rod 404 abuts against the limit block 405, the swing arm 502 continues to rotate counterclockwise, so that the push plate 401 continues to move upward to push the sieve rod 402. At this time, the sieve rod 402 rotates counterclockwise around the central axis of the guide rod 404 under the restriction of the guide rod 404 and the limit block 405. During the counterclockwise rotation of the sieve rod 402, the first slider will rotate around the hinge point between itself and the push plate 401, and the position of the first slider in the third slide groove will change. This design allows the sieve rod 402 to rotate normally. During the counterclockwise rotation of the screening rod 402 , the grafting clamp 701 on the screening rod 402 falls into the first slide groove on the first guide rail 403 along the screening rod 402 through the notch, and then the grafting clamp 701 falls to the grafting position in the first slide groove.
[0034] Then the steering gear 501 changes the direction of the rotating shaft, causing the swing arm 502 to rotate clockwise around the central axis of the rotating shaft, and the swing arm 502 drives the push plate 401 to move downward. The screening rod 402 rotates clockwise under the drive of the push plate 401 and also moves downward to the initial position.
[0035] By repeating the above-mentioned actions, a plurality of grafting clips can be sequentially sent into the first slide groove on the first guide rail one by one.
[0036] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
