Description
Technical field
The present invention relates to a kind of sampling head, granular material sampling head in especially a kind of compartment being applicable to granular material sampling.
Background technology
Along with continuing to increase of freight traffic, the inspection workload of goods constantly increases.Powdered, granular bulk need carry out physics, chemical property index test from draw samples in compartment in transporting.Some unit or hand sampling, condition of work is severe.A lot of unit carries out mechanical sampling, current mechanical sampling is serial sampling mostly, quantity of sampling quantity is far away more than the sample size that inspection institute needs, cause very large waste, and after finding quality problems in inspection, be difficult to determine to be the sample that extraction comes from which joint compartment, need a kind of sampling quantity few for this reason, and can clear and definite sample with adopt the method for sampling of compartment corresponding relation.
the content of invention
Technical matters: the object of the invention is the weak point overcome in prior art, obtain simple for a kind of 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, the two groups of worm-and-wheel gears up and down in movable stand are fixed on respectively through cylinder roller bearing symmetry, screw rod is coated with in the worm gear center pit of upper and lower two groups of worm-and-wheel gears, the sidewall of screw rod has axial bar groove, the bottom of screw rod is provided with spiral feeding bucket, the both sides of screw rod are respectively equipped with the end cap be fixed on movable stand, the internal thread matched with screw rod is provided with in the upper worm gear of described upper group of worm-and-wheel gear, the key that can slide in bar-shaped trough on screw rod sidewall is provided with in the lower worm gear of lower group worm-and-wheel gear.
The spiral periphery of described spiral feeding bucket is provided with the baffle plate 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, and screw rod rotates and declines, and facilitates spiral feeding bucket to rotate in goods; Screw translation rises, and in minimizing spiral feeding bucket, sample sheds.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 sample size that inspection institute needs, can specify sample and which saves compartment from, and waste is few, reviews conveniently when finding sample quality problem.Its structure is simple, and it is convenient to control, and sampling amount is few, and spill few, the sample in different compartment 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, is formed primarily 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 to-and-fro movement above vehicle up direction or sampling spot.Upper and lower two groups of worm-and-wheel gears are provided with in movable stand 1, upper and lower two groups of worm-and-wheel gears are fixed in movable stand 1 through cylinder roller bearing 4 symmetry respectively, the upper worm gear 3 that upper group of worm-and-wheel gear comprises worm screw 2 and match with upper worm screw, the lower worm gear 7 that lower group worm-and-wheel gear comprises lower worm screw 6 and matches with lower worm screw, screw rod 5 is coated with in the worm gear center pit of upper and lower two groups of worm-and-wheel gears, the sidewall of screw rod 5 has axial bar groove, 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 avoiding sample to spill.The both sides of screw rod 5 are respectively equipped with the end cap 8 be fixed on movable stand 1, the internal thread matched with screw rod 5 is provided with in the upper worm gear 3 of described upper group of worm-and-wheel gear, the key 9 that can slide in bar-shaped trough on screw rod 5 sidewall is provided with, as shown in Figure 3 in the lower worm gear 7 of lower group worm-and-wheel gear.
Principle of work: upper worm screw 2 and the work of lower worm screw 6 are independently, and movable stand 1 can move to above freight compartment along horizontal rail as required, or moves to above sampling spot.Upper worm screw 2 rotarily drives worm gear 3 and rotates, and screw rod 5 can not rotate due to the effect of key 9, 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 lower worm gear 7 and rotates, and key 9 fixing on lower worm gear 7 drives screw rod 5 to rotate, 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 rotates and rises or fall.Have self-locking action between worm gear and worm screw, when lower worm screw 6 is not rotated, lower worm gear 7 does not also rotate, and upper worm screw 2 is rotated and drives worm gear 3 to rotate, and screw rod 5 can not rotate due to the effect of key 9, and the internal thread of upper worm gear 3 forces screw rod 5 to do axially to rise 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 to rotate, and the key 9 on lower worm gear 7 drives screw rod 5 to rotate, and because screw rod 5 and upper worm gear 3 have threaded engagement, screw rod 5 does to rotate and rises or rotate descending motion.
The course of work: during sampling, screw rod 5 rotates and declines, and the spiral feeding bucket of bottom to rotate in compartment designated depth in granular material, obtains sample.Screw rod 5 vertically rises afterwards, the sample collected is proposed from compartment in spiral feeding bucket, for preventing sample from coming off in spiral feeding bucket or mixing mutually with other places granular material, in screw rod 5 vertically uphill process, does not have rotary motion.
When movable stand 1 moves to above compartment, lower worm screw 6 is rotated, and screw rod 5 rotates decline to be made spiral feeding bucket rotate in goods to 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.Above when movable stand 1 moves to sampling spot, screw rod 5 not rotation axis to dropping to specified altitude, can manually or machinery take off sample.
