Abstract

The invention relates to a power-driven absorption type grain sampling buffer which effectively solves the technical problems that grain damage and excessive impurities can be easily caused as a power-driven sampler is used and sampling result is influenced during the traditional grain sampling inspection. The power-driven absorption type grain sampling buffer comprises a buffer body 1 and a buffer body 2. The buffer body 1 is a spiral buffer tube; a sample inlet 3 is arranged above the buffer body 1; and the buffer body 2 is a cylinder buffer tube. The buffer body 2 is provided with an orifice 4 at the upper end and an orifice 8 at the lower end; the buffer body 2 is internally provided with a conical buffer unit 5; the buffer body 2 is connected with the buffer body 1 by virtue of an orifice 6; and a sample outlet 7 is arranged below the interior of the buffer body 2. The buffer provided by the invention can greatly improve the sampling accuracy of the power-driven grain sampler and can guarantee correctness and fairness of the sampling result.

Description

Electrical suction type grain sample impact damper

Technical field the present invention relates to electrical suction type grain sample buffer device, and this kind device can guarantee that the science of grain quality inspection organization in the grain sampling is just, convenient and reasonable, accurately quick, can be widely used in the pick test of various cereal products.

Background technology generally uses manual grain sample device to carry out the sampling of grain sample in existing grain quality check.Though manually the extraction result of grain sample device is comparatively accurate, its weight is bigger, carries inconvenience, wastes time and energy operation inconvenience, the directly work efficiency of influence sampling in actual mechanical process.Except manual grain sample device, also has existing electronic grain sample device on the market.Though it has extraction advantage relatively easily, can improve the efficient of grain samples, but the electronic sample device of grain existing on the market mostly is to utilize domestic vacuum cleaners or industrial dust collector to convert, in the use and do not meet the characteristics of grain sample, mostly exist motor power (output) excessive, drawbacks such as wind speed is too fast, cause institute's skewer grain crusher rate to increase easily, simultaneously because suction is excessive, cause unnecessary impurity to suck in the sample sample, cause sample impurity apparently higher than the original impurity level of institute's skewer grain.In " State Standard of the People's Republic of China's grain, oil plant check sample, branch sample method GB 5491-85 " 1.1.2.3, stipulate that clearly electrical suction type sample device is unsuitable for the grain quality foreign impurity matters test.Therefore in existing grain quality work for inspection, still use the methods of sampling of manual sample device as the grain sample.

Summary of the invention the purpose of this invention is to provide the impact damper of a kind of electronic grain sample device special use, it can solve the inconvenience of carrying of manual sample device existence effectively, operation is wasted time and energy, problems such as inefficiency, thoroughly overturned the principle of work of electronic in the past sample device, the shortcoming that does not have electronic in the past sample device, its reasonable in design, flexible operation is convenient, significantly improved the sampling accuracy of electronic sample device, guarantee the science of sampling just, convenient and reasonable, accurately fast, handling safety, significantly shorten the required working time of sampling, be convenient to that each grain reserves unit is daily to be checked oneself, help realizing the standardization of grain quality supervision and inspection simultaneously.

Electrical suction type grain sample impact damper comprises: body 1, body 2.Body 1 is the spirality separator tube, and there is an injection port 3 the body top; Body 2 is a right cylinder separator tube.Body 2 upper ends are provided with the mouth of pipe 4, and there is the mouth of pipe 8 lower end; There is a pyramid type snubber assembly 5 body 2 inside, and body 2 connects with body 1 by the mouth of pipe 6, and a setting-out mouth 7 is arranged below body 2 inside.

The present invention changes existing electronic grain sample device, has advantage easy to carry, simple operation.The characteristics of maximum of the present invention are by control and adjusting to electronic sample device sample drawn power, reduce the breakage of grain sample, reduce the impurity level of sneaking into final sample drawn.Farthest improved the breakage that the sample sample causes and formed impurity in extraction process, thus the adverse effect that assay is caused.The present invention can significantly improve the sampling accuracy rate of electronic grain sample device, make the sample result of electronic grain sample device reach the degree of manual grain sample device, fundamentally broken the deadlock of manual grain sample device inefficiency, allow the work of grain quality check develop into electronic extraction from artificial extraction, not only improved the speed of sampling greatly, great amount of manpower and material resources have been saved in the security of operating process.

The invention will be further described below in conjunction with accompanying drawing for description of drawings:

Fig. 1 is the schematic three dimensional views of one of them parts body 1 of the present invention;

Fig. 2 is the schematic three dimensional views of another parts body 2 of the present invention;

Fig. 3 is body 2 in-built schematic three dimensional views of the present invention

Fig. 4 is the schematic three dimensional views of integral body of the present invention;

Embodiment such as Fig. 1 arrive shown in Figure 3, body 1, body 2.Body 1 is the spirality separator tube, and there is an injection port 3 the body top; Body 2 is a right cylinder separator tube.Body 2 upper ends are provided with the mouth of pipe 4, and there is the mouth of pipe 8 lower end; There is a pyramid type snubber assembly 5 body 2 inside, and a setting-out mouth 7 is arranged below body inside.Body 1 connects by the mouth of pipe 6 with body 2, forms an organic whole.

As shown in Figure 3, the grain sample that extracts enters body 1 by injection port 3, by spiral pipeline, according to parabola principle, make the grain sample in the body that enters circular arc be difficult for fragmentation, sample enters body 2 smoothly by the mouth of pipe 6, flow velocity and vibrations that the pyramid type snubber assembly of fixing by internal tank 5 can constantly slow down sample, not only can fit benefit ground and filter, extract the lighter impurity of density, can also minimally reduce the extraction speed of sample.The body 2 upper end mouths of pipe 4 assurance whole pipe inside can comparatively fast not caused the excess pressure of internal tank because of extraction speed, sample is collected precipitation at body 2 internal tanks, last sample can be emitted from the outlet 7 of body 2 lower ends, fall into collection container by the mouth of pipe 8, finish the sampling process of whole grain sample.

That the present invention has is firm in structure, it is convenient, simple to operate to carry, work safety, the advantage rapidly of sampling, the present invention can be equipped with the motor that mates with impact damper and carry out the work of grain sample, changed the inaccurate law of electronic grain sample device sampling results in the grain quality check, realize the mechanization of grain quality work for inspection, greatly improved the efficient of sampling work, save the man power and material, promote the grain quality check to rise to a new height.
