Step 4, starts heater 12 and blower 13, and blower 13 will be in the heat blow to feeder 2 of 12 top of heater
Portion；The driving motor for starting idler wheel 111, enables feeder 2 be in rotation status, heater 12 is while heating air by pedestal
1 top heating, these heats are conducted in placing groove 11 and 2 bottom of feeder is gathered in, as the rotation of feeder 2 is to inside
The ground of sample is evenly heated, and so that the moisture acceleration of pedotheque bottom is evaporated into surface and is taken away by hot wind, to dramatically increase
Step 5, the power by adjusting heater 12 and blower 13 can control 2 bottom of feeder during heating
Temperature；The adjusting that 25 openings of sizes of the second air outlet is realized by the lifting of control opening and closing part 222, takes with 13 power of blower
It is adjusted with hot wind air quantity in realization feeder 2；
Step 6 closes heater 12 after default air-dry time, and adjusting opening and closing part 222 and moving down makes the second air outlet
25 fully open, and utilize the cooling feeder 2 of cool breeze and its internal sample；
Step 7, sample hold 33 rotary seal lid 3 of handle and open it after the cooling of preset time, take out and add
Sample in feeder 2 is transferred in corase grinding component 5 using material suction device 53, is turned by cooperating by step 8
It is fallen on sieve 61 after dynamic the first roller 51, the grinding of the second roller 52；
Step 9 opens the second vibrator, and sieve 61 is driven to screen sample, and the sample across sieve 61 passes through collection
Hopper 62 is fallen in the cavity 711 in fine grinding component 7；
Step 10, operation nog plate 72 rotate, and sample enters the corresponding fine grinding of abrasive material, nog plate under the effect of 72 centrifugal force of nog plate
Region, centrifugal force persistently plays a role during the grinding process, and soil is made finally to be thrown out of nog plate 72, falls in charging dish, thus
Obtain may be used as the pedotheque of specific detection project.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
