Abstract

The utility model relates to a spring energy-storage sampler, which comprises a front sleeve pipe and a back sleeve pipe which are connected by a hoop-shaped valve seat, wherein, the bottom of the back sleeve pipe is fixedly connected with a lifting jack, a spring is arranged in the back sleeve pipe, a cylindrical slide core is arranged in the hoop-shaped valve seat, the middle part of the slide core is provided with a circle of groove, the inner side of the hoop-shaped valve seat is provided with two circular holes which are larger than a semicircle, lock shafts are inserted in the circular holes, one part of the lock shafts is projected out of the inner wall of the hoop-shaped valve seat, the upper parts of the lock shafts are fixedly connected with lock shaft handles, and the root of a knife bar is inserted on the front end of the slide core. The utility model has the advantages of simple structure, convenient carrying and strong maneuverability and can easily explore and sample various articles with rigid package, and the spring energy-storage sampler can be provided with a long knife bar to increase the exploring and sampling depth through compressing and releasing the spring for many times.

Description

The spring energy-storage sampler

The utility model relates to the utensil of draw samples from bigger packing.

The departments concerned is all taken a sample with sampling appliance as the check of cereal, cotton, wool, chemical fibre etc. to the article of bigger packing, the sampling appliance that uses mainly contains two kinds at present, a kind of is pricker shape hand sampler, this sampler structure is comparatively simple, be suitable for the sampling of loose materials such as cereal, but to then very difficult, quite painstaking by the sampling of article such as the cotton of mechanical packaging (rigid package), wool, chemical fibre; Another kind is the electrodynamic type sampler, though this utensil penetration capacity is strong, saves labor capacity and muscle power, and the equipment heaviness is bulky, needs working power, and maneuverability is poor, and use is restricted.

The purpose of this utility model be to provide a kind of simple in structure, easy to use, penetration power strong, be applicable to the spring energy-storage sampler of various article samplings.

The purpose of this utility model realizes by technical scheme shown in the drawings, it comprises a knife bar and cutter head, the utility model has an anterior cannula and rear sleeve, the front and back sleeve pipe is connected by a hoop shape valve seat, the affixed lifting jack in the bottom of rear sleeve, spring is arranged in the rear sleeve, the top of lifting jack withstands on the bottom of spring, in the hoop shape valve seat a cylindrical slide core is arranged, there is a ring recess at the middle part of slide core, and the back segment diameter of slide core is less than the leading portion diameter, make the rear portion of slide core that a round platform be arranged, the front end sleeve of spring is on the back segment of slide core and withstand on the round platform, and there is the circular hole greater than semicircle of two position symmetries hoop shape valve seat inboard, is inserted with lock shaft in the hole, the part of lock shaft protrudes in the inwall of hoop shape valve seat, drop in the groove of slide core, under this state slide core is pinned, a concave surface is arranged on the lock shaft, when this concave surface turns to hoop shape valve base inner wall, slide core is in open mode, and block with snap ring the bottom of lock shaft, the affixed lock shaft handle in the top of lock shaft; The front end of slide core is a hollow form, and the root of knife bar is inserted in the front end of slide core, and the front end of anterior cannula is fixed a positioning ring that blocks the slide core stroke, and the middle part of knife bar is inserted in the positioning ring.For making the utility model when work stable, can on anterior cannula, fix a hook, hook is colluded on packing material the vibration that produces when reducing work.

In the utility model when work, make slide core be in the lock state earlier, with lifting jack with length of spring compressed, rotate the lock shaft handle again, make slide core be in free release conditions, this moment, the pressure of spring was released, give very big impulsive force of knife bar, make cutter head insert the depths sampling of packing.Of the present utility model relatively simple for structure, be easy to carry, mobility strong can be visited the various article of getting rigid package comparatively like a cork, can be equipped with the rimmer knife bar, increases spy by repeatedly compression and retracting spring and gets the degree of depth, makes sampling more accurate.The utility model also can be used for visiting the cereal of getting bulk packing, and is of many uses.

Accompanying drawing 1 is a cut-open view of the present utility model;

Accompanying drawing 2 is the utility model lock shaft handle arrangement synoptic diagram;

Accompanying drawing 3 is the utility model lock shaft structural representation.
