[0005] Further, the knocking structure includes a knocking rod and a knocking hammer; one end of the knocking rod is hinged to the eccentric wheel mechanism; the other end of the knocking rod is fixedly connected to the knocking hammer.

[0006] Further, a limiting groove is opened on one side of the box body; the end of the knocking rod provided with the knocking hammer extends out of the limiting groove.

[0007] Further, the eccentric wheel mechanism is arranged on the side far from the limiting groove; the eccentric wheel mechanism includes a power source, a motor and an eccentric wheel connected in sequence; the eccentric wheel is hinged to the end of the knocking rod far from the knocking hammer; the power source is electrically connected to the motor; the axis of the eccentric wheel is fixedly connected to the output shaft of the motor.

[0008] Further, a switch is arranged between the motor and the power source.

[0009] Further, the guiding mechanism includes a guiding groove and a guiding key arranged in the guiding groove; the guiding groove is fixed inside the box body and is located above the limiting groove; one end of the guiding key is provided with a limiting member; the other end is fixedly connected to the middle of the knocking rod, and the guiding key penetrates through the guiding groove and is slidably connected to the guiding groove.

[0010] Further, the bottom of the box body is connected to the negative pressure sieve analyzer through a magnet;

[0011] Advantages of the present invention:

[0012] The present utility model provides an automatic knocking device for a negative pressure sieve analyzer, which only drives an eccentric wheel to drive a knocking hammer through a motor; the structure is simple, easy to disassemble and assemble, and the input cost is relatively low; it replaces manual knocking, improves the quality of the test; and improves the instability of the original manual knocking test used by enterprises.
