The working principle is as follows:

before the experiment, at least three groups of cotton straw concrete forming building blocks doped with cotton straws in different proportions are firstly manufactured, the number of each group of building blocks is not less than 3, when the heat conduction detection is carried out, the cotton straw concrete forming building blocks doped with the cotton straws in different proportions can be placed into different detection bins 2, the cotton straw concrete forming building blocks doped with the cotton straws in different proportions are placed under a ceramic heating plate 8 and positioned above a through groove 6, the bottom surfaces of the cotton straw concrete forming building blocks doped with the cotton straws in different proportions are contacted with an aerogel pad 3, a closed door 31 is closed, a ceramic heating plate 8 and a first electric push rod 9 are opened, the heating temperature is set to be 50 ℃ through a temperature controller 30, the heating time is 10 minutes, the first electric push rod 9 pushes an installation seat 11 and the ceramic heating plate 8 to move downwards to be contacted with the top surfaces of the cotton straw concrete forming building blocks doped with the cotton straws in different proportions, the infrared temperature measuring sensor 7 positioned below the through groove 6 detects the temperature of the bottom surface of the cotton straw concrete forming building block doped with cotton straws in different proportions, and displays the value on the temperature display screen 32, the heat conduction efficiency of the cotton straw concrete forming building block doped with the cotton straws in different proportions can be obtained by observing the temperature on the temperature display screen 32, so as to obtain a reference value, the heat conduction efficiency of the cotton straw concrete forming building block doped with the cotton straws in different proportions can be easily compared in a comparison experiment mode, the worker can conveniently determine the doping proportion of the cotton straws, the research and development efficiency of the cotton straw concrete building block is improved, meanwhile, when the compression and shear experiments are carried out, the first digital display hydraulic pump 14 drives the first hydraulic cylinder 16 to push the first pressing plate 17 to carry out compression resistance detection on the cotton straw concrete forming building block doped with the cotton straws in different proportions, the second digital display hydraulic pump 24 drives the second hydraulic cylinder 27 to push the second pressing plate 28 to detect the shearing resistance of the cotton straw concrete molded building blocks doped with cotton straws in different proportions, so that the compression resistance and the shearing resistance of the cotton straw concrete molded building blocks doped with cotton straws in different proportions can be tested simultaneously, the labor is saved, the convenience is realized, the numerical values of the first digital display hydraulic pump 14 and the second digital display hydraulic pump 24 can be used for judging the compression strength limit and the shearing strength limit when the cotton straw concrete molded building blocks doped with cotton straws in different proportions are damaged by workers, the workers can greatly adjust the doping amount of the cotton straws from the aspects of the shearing resistance and the compression resistance, the comprehensive comparison of the heat conduction efficiency of the cotton straw concrete molded building blocks doped with cotton straws in different proportions is facilitated, the optimal proportion is found, and the finished product production of the cotton straw concrete building blocks is facilitated, in addition, after every building block experiment, accessible second electric putter 22 promotes push pedal 18 and removes, thereby release the cotton straw concrete shaping building block that has mixed the cotton straw of different proportions with the experiment completion and bear seat 20 or second and bear seat 29, and the stereoplasm brush 19 through the push pedal 18 bottom surface clears up the first concrete residue that bears seat 20 or second and bear seat 29 top surface, be convenient for the next group of cotton straw concrete shaping building block that has mixed the cotton straw of different proportions to put and carry out the experiment, the trouble of artifical clearance has been saved, the convenience of using is improved, it is more convenient to use.
