Being provided with can move up and down with the matched mallet of soil filling device, mallet, and gravity sensor connects display.
It is provided with packing cloth between soil filling device and the screen frame at top.
The screen frame at top is connect by fixed iron hoop with packing cloth.
The edge of vibratory tray is provided with several inner screws, and fixed iron hoop is fixed by the first fixed screw with inner screw.
The both sides of pedestal are provided with two external screw rods, and soil filling device is fixed by the second fixed screw with external screw rod.
The both ends of mallet are connect with external screw rod.
External screw rod is connect by setscrew with pedestal.
Soil filling device bottom is provided with pumping board.
Power on button, power on button connecting vibration motor are provided on pedestal.
Compared with prior art, soil sample is placed in soil filling device by the utility model, after soil sample is smashed by mallet, soil
Sample falls into screen frame and is sieved, the gravimetric data of the sensor acquisition screen frame of each screen frame bottom, and is shown by display
Out, while screen frame works, the next group soil sample that soil filling device can continue is smashed, and working efficiency is greatly improved；This
When device works, manual intervention is less, easy to operate, has liberated manpower, reduces cost.

Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model includes pedestal 16, is provided with display 10 on pedestal 16, on pedestal 16
Vibrating motor 3 is set, is provided with power on button 2 on pedestal 16,2 connecting vibration motor 3 of power on button, be provided on pedestal 16 with
The connected vibratory tray 4 of vibrating motor 3 is provided with several screen frames 6 in vibratory tray 4, and aperture gradually subtracts screen frame 6 from top to bottom
Small, 6 bottom of each screen frame is both provided with gravity sensor 11, and 6 top of screen frame is provided with soil filling device 9, the sieve of soil filling device 9 and top
Packing cloth 8 is provided between frame 6, the screen frame 6 at top is connect by fixed iron hoop 13 with packing cloth 8, and 9 bottom of soil filling device is provided with pumping
Plate 14,9 top of soil filling device are provided with and can move up and down with 9 matched mallet 15 of soil filling device, mallet 15, gravity sensor 11
Connect display 10.
The edge of vibratory tray 4 is provided with several inner screws 12, and fixed iron hoop 13 passes through the first fixed screw 7 and inner screw
12 fix, and the both sides of pedestal 16 are provided with two external screw rods 5, and soil filling device 9 is fixed by the second fixed screw 17 with external screw rod 5,
The both ends of mallet 15 are connect with external screw rod 5, and external screw rod 5 is connect by setscrew 1 with pedestal 16.
Preferably, screen frame 6 uses traditional round screen frame, top aperture to be more than lower part aperture, 6 size phases of screen frame at different levels
