The material filtered out from interception screen cloth 8 is fallen on arc plate 112 in the presence of deflector 9, then falls on level board 111 again
On, because the spacing between mixing roll 10 and level board 111 is changeless, therefore soil is passing through mixing roll 10 and level
Roller 10 is ground during plate 111 and is ground pulverization process；
The lower section of the abrasive sheet 11 is provided with oscillating plate 13, is disposed with resistive heater 14 in oscillating plate 13, under the oscillating plate 13
Side middle is provided with vibrating device 15, and the vibrating device 15 includes rack 151, the downside of rack 151 and the downside of oscillating plate 13
Middle is fixedly connected, and the left side wall middle of rack 151 is fixedly connected with horizon bar 152, and the left end of horizon bar 152 is fixed
Vertical bar 153 is connected with, the inner bottom part of housing 1 is fixedly connected with the first sleeve 154, and the vertical bar 153 is located at first set
In cylinder 154；The right side of rack 151 is engaged with half gear 155, and the gear teeth of half, half gear are provided with half gear 155
Rotating shaft 156 is fixedly connected with 155, the both ends of rotating shaft 156 are erected on the two side of housing 1, and the outer end of rotating shaft 156 is fixedly connected
There is drive device；Two buffer units 16 are fixedly connected with the madial wall of housing 1 of the lower section of oscillating plate 13；The housing 1
Top is provided with discharge pipe 19, the other end of discharge pipe 19 connection gas chromatograph 18, and pulverized soil is fallen on oscillating plate 13, profit
Rotating shaft 156 is driven to rotate with drive device, rotating shaft 156 drives half gear 155 to rotate, and half gear 155 drives to be meshed therewith
Rack 151 move up；When half gear 155 continues, half gear 155 is separated with rack 151, and rack 151 loses engagement
Decline under gravity after power, so as to realize vibrating effect to oscillating plate 13；After half gear 155 is rotated further, rack
151 can be meshed and then rise with half gear 155 again, so realize the high-efficiency vibration of oscillating plate 13 repeatedly, while heat electricity
Resistance silk 14 works to be heated to soil, accelerates the volatilization of organic contaminants in soil, the mixed gas after volatilization is by going out
Airduct 19 is entered in gas chromatograph 18, and gas chromatograph 18 is analyzed each component in mixed gas, detected.
Valve 3 is provided with the charging aperture 2, prevents mixed gas from being emerged at charging aperture 2.
Described raised 7 be in triangular pyramid.
The abrasive sheet 11 is fixed on inside housing 1 by support frame 12.
The diameter of vertical bar 153 is equal to the internal diameter of the first sleeve 154.
The buffer unit 16 includes second sleeve 161, and the bottom of second sleeve 161 is fixedly connected on the inner bottom part of housing 1, institute
State the inner bottom part of second sleeve 161 and be fixedly connected with the first magnetic pole 162, the top of the first magnetic pole 162 is provided with the second magnetic pole 163, described
First magnetic pole 162 is identical with the polarity of the second magnetic pole 163, passes through buffer spring between the second magnetic pole 163 and the first magnetic pole 162
164 are connected, and the upside of the second magnetic pole 163 is fixedly connected with support column 165, the top of support column 165 and oscillating plate 13
Downside is fixedly connected, ad hoc to be equipped with buffer unit 16, vibration in order to prevent the oscillation intensity during decline of oscillating plate 13 too big
For plate 13 when declining, buffer spring 164 has a upward active force to support column 65, slows down the speed of oscillating plate 13；
Meanwhile second magnetic pole 163 decline after spacing between the first magnetic pole 62 reduce, repulsive force increase therebetween, further reduce
The decrease speed of oscillating plate 13, effectively plays cushioning effect.
The present invention the course of work be:Soil to be comminuted is added at charging aperture 2, the crushing arranged on pulverization roller 5
Tooth 6 carries out preliminary break process to soil, meets that the soil of requirement filters out from interception screen cloth 8, is unsatisfactory for desired soil
Fall on and intercept on screen cloth 8, in the presence of projection 7, soil will not be deposited in the lowest part for intercepting screen cloth 8 so that crushing tooth 6 can
Continue pulverization process will intercept soil on screen cloth 8 and take up；Work of the material filtered out from interception screen cloth 8 in deflector 9
Fall on arc plate 112, then fall on again on level board 111, because the spacing between mixing roll 10 and level board 111 is under
It is changeless, therefore soil is being ground pulverization process by being ground roller 10 when mixing roll 10 and level board 111；By powder
Broken soil is fallen on oscillating plate 13, drives rotating shaft 156 to rotate using drive device, and rotating shaft 156 drives 155 turns of half gear
Dynamic, half gear 155 drives the rack 151 being meshed therewith to move up；When half gear 155 continues, half gear 155 and rack
151 are separated, and rack 151 declines under gravity after losing engagement force, so as to realize vibrating effect to oscillating plate 13；When
After half gear 155 is rotated further, rack 151 can be meshed and then rise with half gear 155 again, so realize oscillating plate repeatedly
13 high-efficiency vibration, while resistive heater 14 works and soil is heated, and accelerates the volatilization of organic contaminants in soil,
Mixed gas after volatilization is entered in gas chromatograph 18 by discharge pipe 19, and gas chromatograph 18 is to each in mixed gas
Component is analyzed, detected；It is ad hoc to be equipped with buffer unit in order to prevent the oscillation intensity during decline of oscillating plate 13 too big
16, for oscillating plate 13 when declining, buffer spring 164 has a upward active force to support column 65, makes the speed of oscillating plate 13
Degree slows down；Meanwhile second magnetic pole 163 decline after spacing between the first magnetic pole 62 reduce, repulsive force increase therebetween, enter one
Step reduces the decrease speed of oscillating plate 13, effectively plays cushioning effect.
