One of the important links of quality control and supervision spot check is to carry out spot check on the fertilizer, and the representativeness of the extracted sample is directly related to the reliability of the test result. The sampling equipment that has now mainly includes simple fluting formula sample borer and concentric circles sleeve pipe side fluting rotary type sample borer, and its head is mostly conical pointed end, has a great deal of inconvenience when going out to sample and carrying, takes public vehicle to cause the injury to personnel on every side very easily.

When the simple slotted sampling drill rod is used for vertically sampling and upwards pulling out a drill body, granular fertilizer which enters a groove body is most easy to flow out, so that the representativeness of the obtained sample is greatly reduced, and particularly the non-homogeneous fertilizer (such as bulk blend fertilizer) with the particle size distribution to be measured is obtained; although the shortcoming of simple slot type sample borer has been avoided to concentric circles sleeve pipe side fluting rotary type sample borer, nevertheless because the side fluting is than longer, the resistance is great when the rotatory closure of inner and outer tube, and granular fertilizer is often blocked in the centre and causes the inner and outer pipe to close easily, has brought the inconvenience in the operation. In addition, the depth of each borer inserted is neglected deeply and neglected shallowly when the sample of simple fluting formula sample borer, concentric circles sleeve pipe side fluting rotary type sample borer, and the sample volume of each borer is many times less, and the sample volume of each bag often also can not reach the volume of standard requirement, and batch sample total volume is more can't estimate, and these factors have led to the sample representativeness of taking out not strong.

On the other hand, the total length of simple slot type sampling drill rod, concentric circle sleeve side fluting rotary type sampling drill rod is generally about 0.7 meter, and the experience is not good but still can be used when being used in the solid bagged fertilizer sampling of packaging specification less than or equal to 50 kilograms, but when being used in the solid bagged fertilizer sampling of packaging specification more than 50 kilograms even ton package fertilizer, because its length limits, brought very big difficulty to the sample. If the total length of simple fluting formula sample borer, concentric circles sleeve pipe side fluting rotary type sample borer increases, it is more convenient and unsafe to carry after the length increases actually, takes out the not strong problem of representativeness of sample and still is difficult to solve.
