Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0031] like Figure 1As shown, a biological pesticide filling and sealing machine for a biological laboratory comprises a box body 1, a rotating shaft 2 arranged in the box body 1 and rotating in the box body 1, and a turntable 3 arranged at the upper end of the rotating shaft 2. The rotating shaft 2 is in a vertical direction, and the upper and lower ends of the rotating shaft 2 are rotatably connected to the box body through bearings. A number of support blocks 4 are evenly arranged on the turntable 3 along the circumferential direction, and the support blocks 4 are provided with through holes 5 for supporting plastic tubes. A cutting mechanism, a grouting mechanism, a sealing mechanism and an ejection mechanism are sequentially provided on the box body 1 along the circumferential direction of the turntable 3, and a driving mechanism for driving the rotating shaft 2 to rotate at intervals is provided at the bottom of the box body 1; in this embodiment, there are five support blocks 4, one of which is open and is used to manually place the plastic tube into the through hole 5, and the support blocks 4 in the clockwise direction correspond to the cutting mechanism, the grouting mechanism, the sealing mechanism and the ejection mechanism. The plastic tube is manually placed into the open support block 4. The turntable 3 rotates a short distance, then stops. The support block 4 moves to the cutting mechanism to cut the plastic tube, leaving the upper end of the plastic tube open. The turntable 3 continues to rotate, and the support block 4 moves to the grouting mechanism to add the biopesticide into the plastic tube. The turntable 3 continues to rotate, and the support block 4 moves to the sealing mechanism to seal the plastic tube. Finally, the support block 4 moves to the ejection mechanism to eject the plastic tube preparation. This achieves automatic processing of plastic tube preparations, high efficiency, and reduced labor intensity.

[0032] The sealing mechanism adopts a high-temperature melting sealing method, which is a prior art and will not be described in detail here.

[0033] like Figure 2 、 Figure 4 and Figure 5 As shown, the driving mechanism includes a gear 6 arranged at the bottom of the rotating shaft 2, a rotating plate 7 arranged at the bottom of the box body 1 and a driving wheel 8 for driving the rotating plate 7 to rotate. The rotating plate 7 is arranged horizontally, and the rotating plate 7 is a right-angled triangular plate. A pawl 9 is provided at the front end of the rotating plate 7 to cooperate with the teeth of the gear 6. The rear end of the pawl 9 is rotatably connected to the angle of the front end of the rotating plate 7. A first tension spring 12 is provided between the pawl 9 and the rotating plate 7. The corner on the left side of the rear end of the rotating plate 7 is rotatably connected to the inner wall of the box body 1. The corner on the left side of the rear end of the rotating plate 7 is provided with a roller 10 that cooperates with the driving wheel 8. A groove 11 is provided on the outer cylindrical surface of the driving wheel 8. The driving wheel 8 rotates continuously. When the roller 10 passes the position of the groove 11, the front end of the rotating plate 7 swings to the left, and the pawl 9 will push the gear 6 to rotate counterclockwise, thereby realizing the intermittent rotation of the gear 6. The intermittent rotation of the gear 6 is realized by the mechanical structure, and the rotation angle is accurate.

[0034] The first tension spring 12 ensures that the pawl 9 always cooperates with the gear 6 and will not separate, and the pawl 9 pushes the gear 6 to rotate reliably.

The axis direction of the driving rod 22 is vertical, and the driving rod 22 is rotatably connected to the inner wall of the box body via a bearing. When the driving rod 22 rotates, the driving disk 24 rotates. When the column 26 moves to the position of the driving block 25, the lifting plate 17 rises, and the lifting rod 18 passes through the through hole 5 to push out the plastic tube preparation, thereby realizing the automatic pop-up of the plastic tube preparation. The ball 27 can reduce the friction between it and the driving block 25.

When the column 26 separates from the drive block 25, the lifting plate 17 is lowered under the action of the compression spring 21 without interfering with the rotation of the drive disk 24.

[0042] like Figure 1 As shown, the cutting mechanism includes a fixed cutter 29 and a movable cutter 30 provided on the box body 1. The movable cutter 30 is movably connected to the fixed cutter 29.
