Sieve analysis experimental machine

Abstract

The invention relates to a sieve analysis experimental machine, which comprises an experimental machine shell, an electric blowing device, a guide device, a net device, a funnel device, a collection box, a weighing device and a processor. The experimental machine shell is positioned on the outer periphery of the sieve analysis experimental machine; the electric blowing device is positioned on theupper portion of the sieve analysis experimental machine; the guide device is positioned below the electric blowing device; the net device is positioned below the guide device; the funnel device is positioned below the net device; the collection box is positioned below the funnel device; the weighing device is positioned below the collection box; the processor is positioned on an inner side of thesieve analysis experimental machine. By control of the net device, sieve analysis operation can be well carried out; by connection with a computer, sand diameters can be judged, a fineness modulus diagram is drawn, and sieve analysis experimental efficiency is guaranteed. In addition, by the sieve analysis experimental machine manual workload can be relieved, manpower resources are saved, and economic benefits and operating efficiency are improved.

Description

technical field [0001] The invention relates to the field of civil engineering materials, in particular to a sieve analysis test machine device. Background technique [0002] In the existing civil engineering material experiments, it is essential to measure the sand rate and draw the fineness modulus curve, and these operations are usually performed manually, which usually leads to errors. The remaining sand may be stuck in the square hole. If the next group of experiments is not careful, it will cause errors in the experimental data. If the next group of experiments is cleaned up, the experiment time will be extended; at the same time, calculate the sand rate and draw the fineness model. When calculating the curve, the amount of data is large, and the calculation is not easy; although the existing blower device can effectively vibrate the sand, the experimental operation is not easy, and it may cause some sand particles to break, and at the same time, the time cannot be eff...

[0002] In the existing civil engineering material experiments, it is essential to measure the sand rate and draw the fineness modulus curve, and these operations are usually performed manually, which usually leads to errors. The remaining sand may be stuck in the square hole. If the next group of experiments is not careful, it will cause errors in the experimental data. If the next group of experiments is cleaned up, the experiment time will be extended; at the same time, calculate the sand rate and draw the fineness model. When calculating the curve, the amount of data is large, and the calculation is not easy; although the existing blower device can effectively vibrate the sand, the experimental operation is not easy, and it may cause some sand particles to break, and at the same time, the time cannot be effectively grasped; To effectively solve this kind of problem, an experimental device that can not only judge the particle size range of sand particles, but also draw the fineness modulus curve, and automatically play the role of blowing air according to the condition of sand particles
