[0002] Before landfilling hazardous waste, during the landfilling process and in the subsequent environmental monitoring stage, in order to ensure that the landfill operation complies with relevant standards and effectively protects the environmental quality, detailed sampling and analysis of the hazardous waste itself and the environment around the landfill site must be carried out. This requires us to strictly detect the waste landfill environment and the hazardous waste itself before landfilling.

[0003] Firstly, due to the internal structure design of the waste detection sample mixing and preparing device, these devices are prone to poor mixing effect, uneven mixing and even caking when mixing samples. This may seriously affect the representativeness of the samples and the accuracy of the test results. Secondly, the existing device is too cumbersome in the step of taking out the collected environmental samples, increasing the complexity of the operation. At the same time, during the process of taking out the soil samples, the samples are prone to falling or scattering, which not only may cause loss of samples, but also may cause secondary pollution to the environment, resulting in that the existing waste detection sample mixing and preparing device is difficult to quickly put into the mixing and preparing instrument after sampling, which to some extent reduces the work efficiency.

[0061] When sampling is needed, the conical barrel 301-2 is inserted into the ground, the control assembly 304 is adjusted to be loose from the connection below the sample preparation assembly 201, then the power assembly 103 is driven by the operation of the motor 101 and synchronously drives the outer cylinder 301-1 and the conical barrel 301-2 to rotate, at this time, the outer cylinder 301-1 drives the control assembly 304, the adjusting assembly 303 and the inner cylinder 302-1 to rotate in the same direction through the tooth block 301-3, so that the device gradually drills into the ground and collects the sample soil, after the collection is completed, the device needs to be taken out from the ground, when sampling is needed, the lock buckle 204 and the door plate 203 are opened, the entrance of the external sample preparation instrument is placed downward in the inner container 202, at this time, the conical barrel 301-2 is vertically upward and the control assembly 304 is adjusted to be fixed below the sample preparation assembly 201, at this time, the motor 101 is started, at this time, the motor 101 drives the outer cylinder 301-1 and the tooth block 301-3 to rotate, at the same time, the tooth block 301-3 drives the control assembly 304 to rotate, at the same time, the control assembly 304 drives the first gear 303-3 to rotate in the opposite direction, so that the helical blade 302-3 rotates in the opposite direction and gradually pushes the collected soil into the external sample preparation instrument below;

[0062] When sampling is needed, the conical barrel 301-2 is inserted into the ground, the control assembly 304 is adjusted to be loose from the connection below the sample preparation assembly 201, then the power assembly 103 is driven by the operation of the motor 101 and synchronously drives the outer cylinder 301-1 and the conical barrel 301-2 to rotate, at this time, the outer cylinder 301-1 drives the second gear 304-1 and the inner cylinder 302-1 to rotate through the tooth block 301-3, because the mounting seat 304-6 can slide outside the slide plate 304-7, the second gear 304-1 will move circumferentially under the driving of the lower seat of the tooth block 301-3 and synchronously drives the first gear 303-3 and the outer cylinder 301-1 to rotate in the same direction, at this time, the outer cylinder 301-1, the inner cylinder 302-1 and the helical blade 302-3 rotate in the same direction while collecting the sample soil by punching downward;

[0063] When sample preparation is needed, the lock catch 204 and the door plate 203 are opened, and the external sample preparation instrument entrance is placed downward in the inner container 202, at this time, the conical barrel 301-2 is vertically above, and the positioner 304-8 is adjusted to be fixed below the sample preparation cylinder 201-1, to avoid the slide plate 304-7 from sliding below the sample preparation cylinder 201-1, at this time, the motor 101 is started, at this time, the motor 101 drives the outer cylinder 301-1 and the tooth block 301-3 to rotate, at the same time, since the positioner 304-8 fixes the position of the mounting seat 304-6, the second gear 304-1 cannot do circular motion and can only rotate, therefore, the tooth block 301-3 drives the second gear 304-1 to rotate, at the same time, the second gear 304-1 reversely drives the first gear 303-3 to rotate, so that the first gear 303-3 discharges the material into the sample preparation cylinder 201-1 through the spiral blade 302-3 when rotating.
