[0052] As a preferred embodiment, referring to Figure 4, the first screening wall 211 and the second screening wall 212 are arranged in the silo 21 in an alternating and staggered manner, the vertical height of the first screening wall 211 is less than that of the second screening wall 212; after the pipette tip 6 is placed in the feeding cavity 21a, the first screening wall 211 and the second screening wall 212 with different vertical heights abut against the pipette tip 6, so that the pipette tip 6 can be tilted towards the first screening wall 211 with a smaller vertical height by its own gravity, thereby quickly falling into the guide groove 213, thereby facilitating to improve the screening efficiency of the pipette tip 6.

[0053] In a specific embodiment, referring to Figure 5 , the guide groove 213 is formed between the first screening wall 211 and the second screening wall 212, of course, the guide groove 213 can be formed between the first screening wall 211 and the inner wall of the silo 21, so as to improve the utilization rate of the internal space of the silo 21 and help to improve the screening efficiency and the number of processing of the device for the pipette tip 6.

[0054] As a further embodiment, referring to Figure 4 and Figure 5 , any guide groove 213 includes a feeding groove 2131 and an arrangement groove 2132 which are connected in communication, the bottom of the feeding cavity 21a is provided with an inclined wall 214, the feeding groove 2131 is arranged on the inclined wall 214 and extends along the inclined direction of the inclined wall 214, the arrangement groove 2132 and the guide rail groove 225 are connected in communication, and the region where the arrangement groove 2132 and the guide rail groove 225 are connected in communication is provided with a guide outlet 215.

The size of the guide outlet 215 is greater than that of the tip end of the pipette tip 6, so that the pipette tip 6 can smoothly pass through the guide outlet 215 and be fed to the guide rail groove 225.

[0055] It should be noted that the part of the first screening wall 211 located in the feeding groove 2131 is arranged in a bent manner with the part of the second screening wall 212 located in the arrangement cavity 21b, in the arrangement cavity 21b, the second screening wall 212 is provided with a connecting wall with the same vertical height as the first screening wall 211, so that the pipette tip 6 in the arrangement cavity 21b can be smoothly horizontally displaced into the guide rail groove 225, and the connecting wall can be provided with a notch portion with a vertical height consistent with that of the first screening wall 211.

[0056] As a preferred embodiment, in order to accelerate the feeding speed of the pipette tip 6; referring to Figure 3, the feeding mechanism 2 further comprises a pushing assembly 24, the pushing assembly 24 comprises a pushing driving piece 241 and a pushing brush 242, the pushing driving piece 241 is installed on the hopper 21, the pushing brush 242 is drivingly connected to a driving end of the pushing driving piece 241, the pushing brush 242 is arranged in the arranging cavity 21b, and the pushing driving piece 241 is suitable for driving the pushing brush 242 to push the displacement of the pipette tip 6 in the arranging cavity 21b to the guide outlet 215.

[0060] As a further implementation, to facilitate the reset of the stop block 232 and ensure effective material blocking effect, recesses for connecting two profiled mutually attracted magnetic attraction members can be respectively arranged on the side surfaces of the stop block 232 and the material blocking seat 231. The subsequent pipette tip 6 needs to overcome the gravity of the stop block 232 and the attraction force of the magnetic attraction member, so that the stop rotation on the stop block 232 gives way to the displacement path of the pipette tip 6. After the subsequent non-accumulative pipette tip 6, the stop block 232 is automatically reset under the action of gravity and magnetic force.
