The powder sample making machine is mainly suitable for making the samples for other powdery materials as well as analyzing and sampling coal.

Description

The pelletized powder samples machine

Technical field: the utility model belongs to testing laboratory granular material sample making apparatus field.

Background technology: the support spring of the sample preparation pot bed of the powdery sampling machine of this model is generally all used 6 at present.Grinding ring less than sample preparation pot internal diameter is housed in the sample preparation pot, a cylindrical grinding block is housed in grinding ring, the location of sample preparation pot forms movingly with the sample preparation pot by sample preparation pot circle on sample preparation pot bed and locatees.The press fastening device of sample preparation pot compresses for the bridge-type both arms, and motor is a three-phase electricity.There is following weak point in said structure: 1, the sample preparation pot is located movingly by sample preparation pot circle, in the course of the work, granular material easily falls into and cooperates slit or bottom surface, pack into and take out sample preparation pot inconvenience, hold down gag is not once press tightly simultaneously, the sample preparation pot also can rotate in the pot circle, influences sample quality; 2, in the sample preparation pot grinding ring is housed, grinding block is housed in the ring, its powder process is by grinding block collision grinding ring and material and the powder process of grinding ring collision material; Big light because of encircling, the powder process effect is little, and grinding ring manufacturing simultaneously increases manufacturing cost than the time-consuming material that takes of grinding block; 3, the sample preparation pot compresses by the both arms bridge-type, has equally also increased manufacturing cost; 4, motor is selected three-phase supply for use, has influenced the use in different occasions.

Summary of the invention:

Technical problem to be solved in the utility model: reducing on the basis of manufacturing cost, sample preparation pot dress is got conveniently, positioning security is reliable, increase grinding block and material in the sample preparation pot impact force and surface of contact, be convenient to the pelletized powder samples machine and use in different occasions.

The technical scheme that solves the problems of the technologies described above:

The utility model comprises the sample preparation pot bed that casing, frame shock mount support, this following bed surface center is lifted with vertical machine, eccentric weight is housed on the arbor, sample preparation pot and hold down gag are housed on the last bed surface, in the sample preparation pot grinding block is housed, it is characterized in that the cylindroid helical-coil compression spring that supports sample preparation pot bed is no less than 3 at least, sample preparation pot register pin is housed on the last bed surface of sample preparation pot bed, 7 font sample preparation pot clamping arms also are housed on this bed surface.This clamping arm level on the position that bed surface 1/2nd sample preparation pots are high on the distance sample preparation pot bed is equipped with sample preparation pot location stop pin, and the bolt and lock nut with the band handle of sample preparation pot coaxial cable is housed on the horizontal arm.Respectively be shaped on the sample preparation pot the bottom of a pan and the cylindrical outer wall and sample preparation pot register pin and the corresponding pin-and-hole of sample preparation pot location stop pin.In the sample preparation pot grinding block is housed, the pot cover of band sealing is housed on the sample preparation pot, the center of pot cover is shaped on bolt and compresses pilot hole.

The beneficial effects of the utility model: 1, because the utility model has removed location pot circle, removed the drawback that the sample preparation pot is got at the work fashionable dress, and transformation of the way back has increased register pin, location stop pin in sample preparation pot clamping, make dress get safe ready, thereby change the both arms bridge-type hold down gag of big snap-in force into 7 font sample preparation pot clamping arms, reduce man-hour and material pin consumption that hold down gag is made, reduced manufacturing cost.2, owing to removed grinding ring in the sample preparation pot, and change a plurality of grinding blocks into, when the eccentric weight on the motor drives the vibration of sample preparation pot bed, a plurality of grinding blocks in the sample preparation pot are big to material impacting power by sample preparation pot wall, improved sample quality, also reduced simultaneously because of the time-consuming cost of system chain rate clamp dog expense material; 3, owing in the sample preparation pot a plurality of grinding blocks are housed, impact is big, thereby power supply is used two phase electricity instead, greatly facilitates the applicable situation of this machine.
