Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.Should be understood that embodiment described herein only is used for description and interpretation the utility model, is not limited to the utility model.
As shown in Figure 1, embodiment of the present utility model provides a kind of sampler, wherein, this sampler comprises rotating shaft 1, sleeve 2 and the sampling jar 3 that can be communicated with described sleeve 2, described sleeve 2 removably is connected on the described sampling jar 3, described rotating shaft 1 comprises that first 7 and second portion 8 and described rotating shaft 1 stretch in the described sleeve 2 from an end of described sleeve 2, described first 7 is contained in the described sleeve 2, described second portion 8 is positioned at outside the described sleeve 2, described rotating shaft 1 can be moved with respect to described sleeve 2, so that described first 7 stretches out from the other end of described sleeve 2.
Sampler is connected with solid state fermentation equipment at the other end of sleeve 2, operation is positioned at the second portion 8 outside the sleeve 2, so that rotating shaft 1 integral body moves with respect to sleeve 2, first 7 stretches out with the material of solid state fermentation equipment inside from the other end of sleeve 2 and contacts, and takes a sample.Then, again operate second portion 8, so that rotating shaft 1 integral body moves with respect to sleeve 2, material is along with in first's 7 retraction sleeves 2 and enter sleeve 2 inside.At this moment, sleeve 2 is communicated with sampling jar 3, material can fall in the sampling jar 3, and then sampling jar 3 disassembled from sleeve 2, finish sampling, and then sample can be sent to detection, thereby can measure the material of the inner different depth of solid state fermentation equipment moisture, pH value, have or not the situation such as microbiological contamination, finally reach detection microbial growth situation.
As shown in Figure 1, for as much as possible sampling, and make things convenient for material in sleeve 1 interior conveying, preferably, described first 7 comprises spire 9, and this spire 9 is provided with helical blade 4, and described rotating shaft 1 can be rotated with respect to described sleeve 2.Operation second portion 8 so that rotating shaft 1 not only moved horizontally with respect to sleeve 2 but also rotated, thereby helical blade 4 rotates along with the rotation of rotating shaft 1, be that rotating shaft 1 and sleeve 2 form small-sized worm conveyor, when thereby first 7 stretches out in the sleeve 2, utilize as much as possible many feedings of revolving force.Then in the process that rotating shaft 1 is retracted, helical blade 4 can be pushed ahead the material sample of getting, so that material can move to the position that sleeve 2 is connected with sampling jar 3, i.e. the position of the opening of Fig. 1 middle sleeve 2 lower ends, and then material is because deadweight falls into sampling jar 3.
