Abstract

Automatic contracting division device is a kind of that sample is efficient according to the division ratio set, and carries out the device of division quickly and accurately, be particularly well-suited to sample moisture high, tough under the conditions of automatic division.Its feature: hopper by total feeding mouth with analyze sample feeding mouth and abandon sample feeding mouth and be connected, two vibrating motor symmetries are fixed on two sides of hopper, by four springs by hopper support on reduction device framework soleplate, division plate is connected with torque motor, division plate uses baffle arrangement, is positioned by bearing.By changing torque motor rotating ratio conduction time, it is achieved being automatically adjusted of division ratio.Present configuration is simple, and compact, rationally, volume is little, and energy consumption is low, and processing and manufacturing is easy, and easy to maintenance, subject range is extensive.

Description

Automatic contracting division device

Technical field

Gather coal, fine granularity or powdery solid material sample, need after online sample preparation Material sample is carried out division according to division ratio set in advance, leaves analysis sample exactly Product amount.Automatic contracting division device analyzes sample size design accurately exclusively for automatically obtaining.

Background technology

In online sample making course, determine quantitative analysis sample to obtain, be typically employed in rotation The radial direction of the division dish turned presets the window of several adjustable openings sizes, window Lower section connects collection sample tank, and the sample flowing through window flows into collection sample tank, is trapped in the contracting of rotation Divide the sample above dish to discard, therefore there is following problems: 1. when the moisture of sample Higher or time viscosity is bigger, the feeding mouth of reduction device and analyze the feeding mouth of sample and easily glue Sample, causes sample mix, causes the feeding mouth of reduction device and analyze the pan feeding of sample time serious Mouth is blocked；2. national standard is crushed to certain grain to the material of a sampling unit collection The amount of keeping sample after degree has clear and definite regulation, and the product population provided every day due to supplier is not With, when gathering the outturn sample of different supplier, need to set different division ratios, In continuous print sampling process, often shutting down regulation division dish window size both wasted time and energy, Affect again being normally carried out of sampling work.

Summary of the invention

The aiming to overcome that the deficiencies in the prior art of patent of the present invention and a kind of adaptation is provided Scope is wide, and volume is little, energy-efficient automatic contracting division device.

The purpose of patent of the present invention is achieved in that automatic contracting division device bolt is by two Vibrating motor 2 symmetry is fixed on two sides of hopper 1, and hopper 1 is by four springs 3 It is supported on the framework soleplate 11 of reduction device 4；With bolt, torque motor 6 is fixed On support 5, support 5 is fixed by bolts on the framework soleplate 11 of reduction device 4, Torque motor 6 output shaft and the support shaft of division plate 12 are by bonded；Hopper base plate 10 by total feeding mouth 9 and abandon sample feeding mouth 7 and analyze sample feeding mouth 8 and be connected； Division plate 12 uses baffle arrangement, is fixed by axle 13, and bearing 14 is passed through at axle 13 two ends Fixing, bearings at both ends 14 is fixed in reduction device 4.

Patent work process of the present invention is as follows: when vibrating motor 2 obtains electric, make hopper 1 Produce high-frequency vibration, drive total feeding mouth 9 and abandon sample feeding mouth 7 and analyze sample pan feeding Mouth 8 shakes together, prevents at total feeding mouth 9 and and abandons sample feeding mouth 7 and analyze sample Sample is adhered on feeding mouth 8；When torque motor 6 obtains electric rotating counterclockwise, division plate Sample feeding mouth 7 is abandoned in 12 coverings, and sample flows into collection sample tank by analyzing sample feeding mouth 8；Power When square motor 6 obtains electric rotating clockwise, division plate 12 covering analyzing sample feeding mouth 8, Sample flows into and abandons sample feeding mouth 7；Lead to counterclockwise and clockwise by changing torque motor 6 Electricity time ratios, it is achieved the change of division ratio, torque motor 6 is counterclockwise and up time Pin ratio conduction time, sets in advance on computer screen, when changing division ratio, Only need to take, when division plate 12 rotate in place, with division by point on operation on-screen menu Device 4 frame side impact, makes division plate 12 produce vibrations, will stick to division plate 12 On sample shake off, reach to prevent the purpose of division plate 12 surface adhesion sample.

Owing to using such scheme, making reduction device be not likely to produce blocking, division plate 12 is difficult to Adhering to sample, division ratio regulation is simple, efficiency is high, is widely used in various bulk material Division.

Being proved by application practice for many years, this technology using effect is good, the sample of collection When coal free surface moisture is up to 20%, system does not blocks, and is widely used in mechanization and exists In line sample making apparatus.
