3. A sample weighing apparatus as claimed in claim 2, wherein: The weighing mechanism (4) also includes a vibration mechanism (47); the vibration mechanism (47) works in conjunction with the placement platform (48) to apply a vibration force to the sample cup (5) stored in the placement seat (49).

4. A sample weighing apparatus as claimed in claim 3, wherein: The weighing mechanism (4) also includes an elastic reset member (46); multiple elastic reset members (46) are distributed between the placement platform (48) and the base plate (41).

5. A sample weighing device as described in claim 2, characterized in that: The weighing mechanism (4) also includes a detection sensor (44); the detection sensor (44) is provided on the corresponding placement seat (49) to detect whether there is a sample cup (5) in the placement seat (49).

6. A sample weighing apparatus as claimed in claim 2, wherein: The weighing mechanism (4) also includes a temperature sensor (45).

7. A sample weighing apparatus as claimed in claim 1, wherein: It also includes a conveying mechanism (3); the transfer mechanism (2) is capable of transferring the sample cup (5) on the conveying mechanism (3) into the tray (43), or transferring the sample cup (5) onto the conveying mechanism (3).

8. A sample weighing apparatus as claimed in claim 7, characterised in that: The conveying mechanism (3) includes an input mechanism (31), an output mechanism (34), and a limiting baffle (331); the limiting baffle (331) is located at the end of the input mechanism (31) to block the sample cup (5).
