Description
Technical field
The present invention relates to a kind of sampling head, granular material sampling head in especially a kind of compartment that is applicable to granular material sampling.
Background technology
Along with continuing to increase of freight traffic, the check workload of goods constantly increases.In Powdered, graininess Bulk Transport & its, need carry out physics, chemical property index test from draw samples in compartment.Some unit or hand sampling, condition of work is severe.A lot of units have carried out mechanical sampling, current mechanical sampling is serial sampling mostly, quantity of sampling quantity is far away more than the required sample size of check, cause very large waste, and in check, find to be difficult to determine to be the sample that extraction comes from which joint compartment after quality problems, need a kind of sampling quantity few for this reason, and the method for sampling of the clear and definite sample of energy and the compartment corresponding relation of adopting.
the content of invention
Technical matters: the object of the invention is to overcome the weak point in prior art, obtain for a kind of simple in structure, control convenient, sampling amount is few, granular material sampling head in effective compartment.
Technical scheme: granular material sampling head in compartment of the present invention, comprise movable stand, through cylinder roller bearing symmetry, be fixed on the two groups of worm-and-wheel gears up and down in movable stand respectively, in the worm gear center pit of two groups of worm-and-wheel gears, be coated with screw rod, on the sidewall of screw rod, have axial bar-shaped trough, the bottom of screw rod is provided with spiral feeding bucket, the both sides of screw rod are respectively equipped with the end cap being fixed on movable stand, in the upper worm gear of described upper worm-and-wheel gear, be provided with the internal thread matching with screw rod, in the lower worm gear of lower worm-and-wheel gear, be provided with the key that can slide in bar-shaped trough on screw rod sidewall.
The spiral periphery of described spiral feeding bucket is provided with the baffle plate of avoiding sample to spill.
Beneficial effect: the present invention is by screw rod and two groups of worm-and-wheel gears up and down of coordinating with screw rod, and in control, worm screw or lower worm screw are rotated, and just can make screw rod rotation and lifting or translation lifting, screw rod rotation declines, and facilitates spiral feeding bucket to rotate in goods; Screw rod translation is risen, and reduces shedding of the spiral feeding interior sample of bucket.Spiral feeding bucket adopts on spiral periphery and turns over structure, avoids sample to spill.This device number of samples is few, can meet the required sample size of check, can which save compartment from by clear and definite sample, and waste is few, while finding sample quality problem, reviews conveniently.It is simple in structure, and it is convenient to control, and sampling amount is few, spills less, and the sample in different compartments is not obscured.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present invention;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the B-B view of Fig. 1;
Fig. 4 is figure D view.
In figure: movable stand 1, upper worm screw 2, upper worm gear 3, cylinder roller bearing 4, screw rod 5, lower worm screw 6, lower worm gear 7, end cap 8, key 9.
Embodiment
Below in conjunction with accompanying drawing, one embodiment of the present of invention are further described:
As shown in Figure 1, granular material sampling head in compartment of the present invention, mainly consists of movable stand 1, worm gear, worm screw and screw rod 5, and movable stand is framed structure, can move along the horizontal guide rail in Sampling Machine, make sampling head above vehicle or to-and-fro movement above sampling spot.In movable stand 1, be provided with upper and lower two groups of worm-and-wheel gears, upper and lower two groups of worm-and-wheel gears are fixed in movable stand 1 through cylinder roller bearing 4 symmetries respectively, upper worm-and-wheel gear comprises worm screw 2 and the upper worm gear 3 matching with upper worm screw, lower worm-and-wheel gear comprises lower worm screw 6 and the lower worm gear 7 matching with lower worm screw, in the worm gear center pit of two groups of worm-and-wheel gears, be coated with screw rod 5, on the sidewall of screw rod 5, have axial bar-shaped trough, as shown in Figure 2; The bottom of screw rod 5 is provided with spiral feeding bucket, and the spiral periphery of spiral feeding bucket is provided with the baffle plate of avoiding sample to spill.The both sides of screw rod 5 are respectively equipped with the end cap 8 being fixed on movable stand 1, in the upper worm gear 3 of described upper worm-and-wheel gear, be provided with the internal thread matching with screw rod 5, in the lower worm gear 7 of lower worm-and-wheel gear, be provided with the key 9 that can slide in bar-shaped trough on screw rod 5 sidewalls, as shown in Figure 3.
Principle of work: upper worm screw 2 and 6 work of lower worm screw are independently, and movable stand 1 can move to freight compartment top along horizontal rail as required, or move to sampling spot top.Upper worm screw 2 rotarily drives worm gear 3 rotation, and screw rod 5 is because the effect of key 9 can not be rotated, upper worm gear 3 and screw rod 5 threaded engagement, and the internal thread of upper worm gear 3 drives screw rod 5 to rise or decline.Lower worm screw 6 rotarily drives 7 rotations of lower worm gear, and on lower worm gear 7, fixing key 9 drives screw rods 5 rotations, and because screw rod 5 and upper worm gear 3 have threaded engagement, and upper worm gear 3 is motionless, and screw rod 5 just rotate liter or falls.Between worm gear and worm screw, have self-locking action, when lower worm screw 6 is not rotated, lower worm gear 7 does not rotate yet, and upper worm screw 2 is rotated and drives worm gear 3 rotations, and screw rod 5 is because the effect of key 9 can not be rotated, and the internal thread of upper worm gear 3 forces screw rod 5 to do axial rising or descending motion.When upper worm screw 2 is not rotated, upper worm gear 3 does not rotate, and lower worm screw 6 drives lower worm gear 7 rotations, and the key 9 on lower worm gear 7 drives screw rods 5 to rotate, and because screw rod 5 and upper worm gear 3 have threaded engagement, screw rod 5 does that rotation is risen or rotation descending motion.
The course of work: during sampling, screw rod 5 rotations decline, the spiral feeding bucket of bottom rotates into the interior designated depth of granular material in compartment, obtains sample.Screw rod 5 vertically rises afterwards, the sample collecting is proposed from compartment, for preventing that sample from coming off or mixing mutually with other places granular material in spiral feeding bucket, do not rotatablely move in the vertical uphill process of screw rod 5 in spiral feeding bucket.
Movable stand 1 moves to compartment when top, and lower worm screw 6 is rotated, and screw rod 5 rotations decline and spiral feeding bucket rotated in goods, get the musters of goods for sale; Upper worm screw 2 is rotated, and screw rod 5 not rotation axis drives sample in spiral feeding bucket to proper height to rising.Top when movable stand 1 moves to sampling spot, screw rod 5 not rotation axis to dropping to specified altitude, can be manually or machinery take off sample.
