Because of the insertion arrangement between the bearing frame 32 and the material supporting frame 1, the insertion blocks 361 can always be aligned to be inserted into the spline cylinder 224 at the corresponding position, in addition, the clamping joint 36 and the spline cylinder 224 are arranged in a clamping manner, so that after the driven shaft 34 is driven to rotate, the clamping joint 36 synchronously rotates, in the rotating process, under the elastic force of the spring piece 363, the two clamping sliding blocks 362 can be correspondingly and rotatably clamped in the two spline grooves one by one, and when the bearing frame 32 is dismounted, the clamping joint 36 can be rapidly pulled out of the spline cylinder 224, the whole matching clamping process is completely and automatically carried out, the problem of rotation alignment is not needed to be considered, and the trouble that the end of the driven shaft 34 is in butt joint with the top end of the rotary drying hopper 22 by manual adjustment is avoided.
In the detection device provided by the invention, a plurality of plugging and clamping assembly connection settings are adopted, specifically, the sample charging barrel 2 is positioned and plugged in the plugging ring 121, the bearing frame 32 is detachably arranged on the supporting tray 12 through the plugging and plugging cooperation of the plugging barrel 321 and the positioning frame 13, and on one hand, the driving shaft 33 rotatably arranged on the bearing frame 32 is sleeved on the square block 311 through the sleeve hole 331, and on the other hand, the driven shaft 34 rotatably arranged on the bearing frame 32 is connected on the rotary drying hopper 22 through the clamping cooperation of the clamping joint 36 and the spline barrel 224, so that the convenience in dismounting of the bearing frame 32 and the sample charging barrel 2 is greatly improved.
When outdoor soil sampling is performed, the bearing frame 32 can be rapidly detached, then the four sample barrels 2 are sequentially detached, four soil samples are randomly sampled in a sampling land and are correspondingly contained in the four sample barrels 2 one by one, after each sampling is completed, in order to avoid the influence of external environment on the quality of the soil samples before drying, the integral quality of each soil sample and the sample barrels 2 should be measured in time, and the mass of the corresponding sample barrels 2 subtracted from the integral quality is the initial quality of the sampled soil; finally, four sample cartridges 2 containing soil samples are intensively placed on the material supporting frame 1.
When drying the soil sample, can place the operation of drying in 105 constant temperature stoving incasement with whole device, before putting into, start driving motor 31, driving motor 31 passes through the output shaft and drives drive shaft 33 rotation, drive shaft 33 passes through drive belt 35 and drives four rotatory drying hoppers 22 rotation in step, in the stoving incasement, rotatory drying hoppers 22 that are in the rotation state stir sample soil through stirring wing plate 223, thereby promote the quick evaporation loss of soil moisture, soil stirring in-process will pass flash breach 2231, thereby can break up the soil of partial caking and make soil fully disperse, then increase the thermal evaporation contact surface of soil moisture, compare with traditional placing sample soil in the tray of weighing and carrying out static stoving, drying effect is greatly enhanced, drying efficiency improves greatly.
After the full drying is completed, the four sample charging barrels 2 are detached one by one and taken out, the residual mass of each sample charging barrel 2 is weighed, the corresponding difference is the mass of water contained in the sampled soil in each sample charging barrel 2, the percentage ratio of the mass of water to the sampled soil is the water content of the corresponding sampled soil sample, and the average value of the measured water content of the four sampled soil samples can be used as the real water content of the detected soil plots. Because the rotary drying hopper 22 with the rotatable stirring function in the sample charging barrel 2 is in rotary driving by being clamped with the shaft end of the driven shaft 34, if an external stirring structure is adopted, the quality of the sampled soil sample is inevitably lost.
