Description
Technical field
The utility model relates to a kind of sampler, is specifically related to a kind of device that can take a sample to the bulk material of powdery or fine granularity.
Background technology
In the process of bulk material (as cement etc.), need be to the detection of taking a sample of processed bulk material.Present sampler generally is made of charging aperture, horizontally disposed stopple coupon, the sampling structure that is arranged in stopple coupon, drives structure and discharging opening, drives the sampling structure motion by drives structure, bulk material is brought to discharging opening from charging aperture take out.As, China utility model patent CN2488057Y discloses a kind of sampler of sped structure, its basic structure promptly as mentioned above, wherein, constitute sampling structure by screw conveyor shaft, by motor as drives structure, it is by the rotation of driven by motor screw conveyor shaft, vibration by screw rod and powder room machine collision generation makes material move along thief rod, flows out from discharging opening.This structure uses motor as power, exists too problems such as heaviness; Simultaneously when sampling, in case motor stops, screw conveyor shaft also stops, and the material that is not transported to the discharging opening place will be retained in the delivery pipe and tube wall on, this part material of being left over influences precision of test result with at first discharging when sub-sampling down.
The applicant has proposed a kind of powder automatic sampler in Chinese utility application 03221244.5, its stopple coupon also is horizontally disposed, it comprises electromagnet chamber, feed space, feed pipe and control device, feed space is between feed pipe and electromagnet chamber, the feed space below is provided with discharging opening, have charging hole on the feed pipe, be provided with thief rod in the feed pipe, thief rod is similarly horizontal positioned.It produces magnetic by the electromagnet energising and makes the excellent thief rod work that drives that drives, and outage rear drive rod resets under the effect of spring with thief rod, thereby finishes sampling work.This kind structure does not need motor, has solved defectives such as the motor of above-mentioned sampler is overweight, and by isolation structure electromagnet chamber and feed space is separated, and prevents that material from entering the electromagnet chamber, damages the electromagnet chamber, increases the service life.But the sampler of this kind structure exists equally that material is retained in the thief rod and the thief rod wall on problem, make sampling work can't accomplish accuracy and representativeness.
Summary of the invention
The utility model purpose provides a kind of bulk material sampler, and after primary sample, do not have material and leave over, thus the accuracy of assurance sampling.

When the sampling of the higher bulk material of the cement equitemperature that is used for process, for avoiding the electromagnet heat damage, and dust enters in the drives structure, can between described electromagnet and sampling support, be provided with spring base and heat insulation structural, drive between rod and spring base and be provided with spring, described heat insulation structural is made of a plurality of heat insulating mattress, screw and the heat shield that are positioned between spring base and sampling support.
Perhaps, the junction of described sampling support and feed pipe is provided with spring base, and thief rod is provided with locating part, and is overheated for avoiding electromagnet, can offer louvre on housing.
Another kind of available drives structure scheme is, described drives structure is a motor-driven structure, is made of motor, reduction gearing and worm and gear, and an end of thief rod is fixedlyed connected with worm screw.
For guaranteeing the motion orientation of thief rod, avoid the lid skew to cause charging aperture to be not closed completely, be provided with the thief rod position limiting structure near described charging aperture, described thief rod position limiting structure can have 2 class schemes, and one is, on thief rod, be fixed with the keeper of fin shape, the outer rim of keeper and feed pipe inner chamber are slidingly matched, usually, and the tubular structure of described keeper central authorities for being threaded with thief rod, periphery is made of the fin of 3 to 4 circumferentially extendings, and fin can slide with respect to feed pipe.
It two is, is provided with the spacing ring that cooperates with thief rod at the feed pipe inner chamber, and spacing ring is fixedlyed connected with feed pipe by 3 to 4 radial connecting links.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1. because feed pipe of the present utility model is in tilted layout, and the angle between tube wall and surface level is greater than the slip critical angle of bulk material on tube wall, thereby each sampling is when finishing, close lid after, do not have leftover materials in the feed pipe, guaranteed the accuracy of sampling;
2. the sampling control structure that is made of lid, thief rod and drives structure is simple in structure, easy to make, does not need structures such as screw rod of the prior art, has reduced production cost.
