Impeller 32 is all taken out of, and subsequent lifting motor 37 is rotated backward, and drives slide 35 to rise until upper proximity transducer 351 is sensed
Stop during upper sensing chip 361, now lifting motor 37 shuts down, the process that fetches earth is completed.
Weighing is tested pits native weight and measuring of moisture content：
Native box 8 will be stored up and be placed on weighing frame 62 weight fetched earth by the weighing of weighing sensor 61, and manually take out two parts of examinations
Sample, every part of about 100-150g is added in the crucible 73 of graphite material, starts water cut test, carries out soil body drying about 8-10min,
Then average moisture content data are taken.
Fill sand：
Start and fill sand, now store up the electrically operated valve of the bottom of sand bucket 4（Do not indicated in figure）Unlatching, toward filling, sand bucket 51 is interior to be added storage sand bucket 4
Enter normal sand and stop until filling after the weight of sand bucket 51 reaches 9000g, fill the weight of sand bucket 51 and weighed by filling sand weighing sensor 52.With
Motor 91 is rotated backward afterwards, promotes drive screw 93 to turn right rotated down by universal joint 92, and movable frame 2 is from lower left
Swing to the right, until right proximity transducer 22 stops after sensing right sensing chip 12, now fill sand bucket 51 and be moved to just now
The position fetched earth and close proximity to ground, the controlling switch valves 53 of PLC 200 are opened（This implementation breaker in middle valve 53 is flat valve）Expose filling sand
The Tapered Cup 511 of 51 bottoms of bucket, in normal sand is flowed into from the filling sand hole at the center of Tapered Cup 511 and tested pits, after this process about carries out 90s
Fill the internal standard sand of sand bucket 51 no longer to decline, the control controlling switches of PLC 200 valve 53 is closed and fills sand hole, and now motor 91 is positive
Rotate, movable frame 2 moves to initial position, now filling sand weighing sensor 52 is weighed and obtains the weight for filling sand bucket 51, with reference to
Native weight of testing pits and cone sand weight, normal sand density are calculated the weight and volume of the sand in testing pits, and are calculated soil
Volume density.
Moisture content is calculated with compactness：
The slightly time is waited, two groups of graphite crucibles 73 complete the drying of the soil body, and moisture content weighing sensor 74 completes graphite crucible
Weighing for soil sample is dried in 73, average moisture content is calculated, and by the number such as average moisture content and field measurement soil body density
According to the actual compactness for being calculated the measuring point.
Antiquated sand is reclaimed：
Start antiquated sand recycling bin 100, the sand suction pipe 101 on antiquated sand recycling bin 100 is stretched into middle suction sand of testing pits, antiquated sand suction is useless
In sand recycling bin 100.
