Abstract
The utility model relates to powdery material sampling equipment, specifically a worm wheel type sampler. The sampler is composed of a worm wheel, a supporting device and a sample collection box, wherein, the worm wheel is arranged on one side of a machine case of a helical conveying machine through the supporting device, the transmission between the worm wheel and a helical blade is a worm type, the helical blade drives the worm wheel to rotate, and materials are sent out by wheel teeth of the worm wheel and are pushed into the sample collection box. The utility model has the advantages of simple structure, little tear and wear of the helical blade, small required power, reliable work, and convenient adjustment and maintenance.
Description
The utility model relates to a kind of granular material sampling equipment, exactly is a kind of worm-gear type sampler.
Cement, chemical industry and need carry the manufacturing enterprise of sampling to granular material will be produced the product that reaches state quality standard, and the extraction of sample also is a side of outbalance, and sample has directly influenced the accuracy of product testing result.Existing granular material sampler such as chain transmission spoon formula sampler, it is the rotation that utilizes the helical blade axle, by the scoop of getting on chain transmission and the chain, material is taken out, this material mode of getting is similar to chapelet.There is the problem of several respects in it: the one, and, complex structure; The 2nd,, change bigger to worm conveyor; The 3rd,, it is bigger that running part is dipped in the material wearing and tearing, easily takes off accidents such as chain.Club formula sampler for another example, it is to utilize in the helical blade rotation process, the principle that blade edge constantly rotates vertically outwards promotes steel ball, thereby periodically opens discharge door, reaches the purpose of sampling.There is the problem of two aspects in it: the one, and, bigger to blade wear; The 2nd,, easily that helical blade is stuck, cause accidents such as burning motor.
The purpose of this utility model is: provide a kind of little to the helical blade wearing and tearing, low, safe and reliable worm-gear type sampler consumes energy.
Its technical solution is as follows:
A kind of worm-gear type sampler, form by worm gear, fulcrum arrangement and sample-collecting box, it is characterized in that: the outside of worm conveyor casing is provided with a fulcrum arrangement, worm gear is by being located on the fulcrum arrangement, worm-wheel shaft is perpendicular to the helical blade axle, be the transmission of Worm-gear type between worm gear and the helical blade, the outside of worm gear and fulcrum arrangement is provided with sample-collecting box.
Its beneficial effect is embodied in following six aspects:
One, this worm-gear type sampler is simple in structure, less to the change of conveying equipment;
Two, reasonable in design, little to the wearing and tearing of helical blade, the serviceable life of having improved equipment;
Three, this worm-gear type sampler required drive is less, has energy-saving and cost-reducing effect;
Four, this sampler reliable operation can not cause the stuck left alone without help car accident of conveying equipment;
Five, this sampler is adjusted, is overhauled conveniently;
Six, the accuracy of this sampler extraction sample is higher.
Description of drawings:
Fig. 1 is the utility model structural front view,
Fig. 2 is the utility model structure vertical view.
Below in conjunction with drawings and Examples the utility model is further described.
By visible this worm-gear type sampler of Fig. 1, Fig. 2, form by worm gear 4, fulcrum arrangement 1 and sample-collecting box 2, fulcrum arrangement 1 is fixed on the outside of worm conveyor casing 5, worm gear 4 is installed on the fulcrum arrangement 1 by axle, worm-wheel shaft is perpendicular to the helical blade axle, be the transmission of Worm-gear type between worm gear 4 and the helical blade 3, drive worm gear 4 by helical blade 3 and rotate that worm gear 4 is installed with sample-collecting box 2 with the outside of fulcrum arrangement 1.
During work, along with the rotation of helical blade axle, helical blade 3 promotes worm gear 4 and rotates, and the gear teeth of worm gear 4 are dialled in sample-collecting box 2 with material.The gear teeth on the worm gear 4 are several, and the gear teeth are six among this embodiment, and helical blade 3 revolutions move a week, and worm gear 4 is dialled changes gear teeth.
