Abstract
The utility model discloses a rock (ore) density measuring instrument, belonging to a special instrument for measuring physical properties in the geophysical exploration and comprising a load sensor, an amplifier, an analog to digital converter, a single chip computer, a controlling and displaying part, a liquid container, etc. The rock (ore) density measuring instrument not only can measure the density of the rock (ore), but also can measure the weight, volume, pore space and humidity of the rock (ore), and the utility model automatically measures, raising the measuring precision and the measuring speed, raising the work efficiency and reducing the artificial error.
Description
Rerum natura in the ball physical prospecting of the utility model possession is measured instrumentation.
Now being used for geophysical survey measures the instrument of rock (ore deposit) stone density two kinds of balance-type type gravimetry instrument and mechanical type gravimetry instruments is arranged.With balance-type type gravimetry instrument test rock sample ore product density value, need add the subtraction sign indicating number, manual operations, manual record and artificial calculating, complicated operation, inefficiency; And during mechanical type gravimetry instrument test rock mineral density, at first need use the weights leveling, and again sample is immersed in the water, wait folding arm balance, so efficient is low, the total indicator reading error is big, limited by index dial, the low (0.1-0.02g/Cm of measuring accuracy
3) etc.
The purpose of this utility model just is to overcome above-mentioned shortcoming, provides a kind of new rock sample ore product density measurement instrument, to increase work efficiency and measuring accuracy.
Rock (ore deposit) stone gravimetry instrument, when specimen density, sample 9 is placed on the hook 10, send steering order, the weight of sample converts corresponding voltage signal to by strain-type load sensor 1, send amplifier 2 to amplify, offer single-chip microcomputer 4 acquisition process through analog to digital converter 3, recording the aerial weight of sample is P
1, drive liquid containers 8 with hoistable platform 7 then and rise to sample 9, making sample 9 be immersed in proportion fully is that at this moment recording the weight of sample 9 in liquid is P in 1 the liquid container
2, will record sample 9 aerial weight P by single-chip microcomputer 4 again
1With the weight P in the liquid
2Automatically handle by the handling procedure in the program storage 5, draw the density value of institute's test sample product 9, and give display system 6, promptly finish the mensuration of a sample rate value.For lacunose rock sample ore product, can adopt the way of waxing, in air, measure P
1Behind the result sample 9 is coated with the sealing of one deck paraffin, the sample 9 aerial weight that record after the waxing are P
2, then institute's test sample product 9 are immersed in proportion and are in 1 the liquid, recording weight is P
3, handle by the Automatic Program in single-chip microcomputer 4 and the program storage 5, calculate density value and give display system, promptly finish the density measurement of vuggy rock sample ore product.
Utilize the said rock of the utility model (ore deposit) stone gravimetry instrument, as long as sample is placed on the hook 10, send the density value that test instruction can be measured sample fast, improved testing efficiency, owing to adopted strain-type load sensor 1 and single-chip microcomputer 4, utilize the program in the program storage 5 to carry out data processing, make measuring accuracy bring up to 0.05--0.005g/Cm
3The numeral demonstration has reduced artificial error, also can connect automatic record test data of printer and sample sequence number etc.In addition, also can test weight, volume, factor of porosity and the humidity etc. of rock sample ore product.
Description of drawings:
Embodiment: the utility model records the example weight corresponding voltage value by strain-type load sensor 1, giving amplifier 2 amplifies, give analog to digital converter 3 again and convert digital quantity to, carry out data processing by single-chip microcomputer 4 and program storage 5, data after handling are delivered to display system 6, can read the density value of institute's test sample product, so that record, as the need print record, connect printer and provide instruction and can realize.
Claims (1)
1, a kind ofly claims rock (ore deposit) the stone gravimetry instrument that arm, hook, scale pan and support etc. constitute by pointer, semicircle scale, folding formula, it is characterized in that it being by strain-type load sensor 1, amplifier 2, analog to digital converter 3, single-chip microcomputer 4, program storage 5, control and display system 6, hoistable platform 7, liquid container 8 constitutes.
