Abstract

The utility model relates to a portable miniature sample crusher which is used for preparing test analytic samples. A micro motor is used as a power source and is fixedly connected with a cylinder body. A motor shaft in the cylinder body is connected with a rotary shaft which is provided with a flying hammer with a grinding head. The upper part of the flying hammer is also provided with a sample tray. The high-speed rotation of the motor is used for driving the flying hammer on the rotary shaft to rotate. Corresponding movement with the inner wall of the cylinder body is used for rapidly grinding the samples. When the samples to be crushed exceed prescriptive sample crushing quantity, the sample tray can lighten resistance during start-up. The utility model has the advantages of small size of the whole portable miniature sample crusher and portability and is suitable for the occasions of flowing work. Rapid sample crushing is realized for satisfying an analytic need.

Description

The portable minisize crusher

The utility model belongs to size reduction machinery, is a kind of portable minisize crusher of pulverizing sample for test.

Industrial production and scientific research all be unable to do without assay, for all kinds of productions and scientific research provide basic data, and various assays all have certain requirement to the granularity of sample, sample preparation--the broken sample that will do before the analysis that Here it is, for the laboratory that certain scale is arranged, all be provided with all kinds of pulverizers and finish this requirement, yet for mobile operation or lack occasion between broken sample, just need a kind of portable small-sized crusher, to cooperate on-the-spot analytical work.

The purpose of this utility model is, a kind of portable minisize crusher is provided, with the deficiency of compensation prior art.

Following mode can realize the utility model:

The portable minisize crusher comprises motor, and with cylinder body and rotary grinding device that motor connects firmly, a support and motor connect firmly, support and cylinder body connect as one, motor shaft is connected with rotating shaft, and rotating shaft places in the cylinder body by cylinder bottom, and the rotating shaft upper end connects flyball or the broken sample cutter that has grinding head.

Connect a clamp nut that has gap that is used for fastening flyball topmost at rotating shaft, sample tray with bayonet snaps in the clamp nut gap along slideway.

The utility model is convenient for carrying, grind at a high speed, can be crushed to the desired granularity of assay, cylinder cap good airproof performance to sample in the short time, no dust leaks, the spline shaft joint reduces the power attenuation of motor to greatest extent, with load-shedding equipment, when slightly surpassing the specified crushed sample amount of crusher for sample, can add sample tray, resistance when alleviating electric motor starting, consumable accessory are that changeable type is installed, and complete machine stability is good.

Embodiment:

Motor 11 bottoms are fixed on the cylinder base 10, cylinder-shaped bracket 4 connects firmly with motor 11 upper ends, be symmetrical arranged two L shaped grooves 15 on the support 4, cylinder body 2 inserts support 4 along slideway, symmetrically arranged two steady nails 16 are gone into the L shaped groove of support 4 on the cylinder body 2, be stuck in the termination of L shaped groove 15, cylinder body 3 and support 4 are become one, internal gear 9 on the motor shaft is meshed with external gear 8 on the rotating shaft 7, interior external gear constitutes the spline shaft joint of loose fit, its compensation diaxon is to the error at center, and the rotating shaft 7 in the cylinder body 2 is connecting cylinder bottom 3 by the bearing in the bearing box, and rotating shaft 7 upper ends connect the flyball 6 that has grinding head 12, grinding head 12 is fastening by screw 13 with flyball 6, it is suitable for pulverizing the bulky grain sample, and grinding head 12 is consumable accessorys, can in time change.With the sample difference of pulverizing, broken sample cutter also can be installed on the rotating shaft 7, during as pulverizing soil class sample, stud with sealing ring in the cylinder cap 1, leak with dust protection.

Connect one topmost at rotating shaft 7 and be used for fastening flyball 6, the clamp nut 17 that has gap, there is a through hole at the center of a sample tray 5, length is striden through hole greater than the short column 18 of through-hole diameter and is welded on sample tray 5 bottom surfaces, the space is left in the short column both sides, makes sample tray 5 form a bayonet socket, and sample tray 5 with bayonet is lowered in the clamp nut 17 along slideway, short column is stuck in the gap, can not fly out during the pallet rotation.When the sample overload of pulverizing, can add and load onto sample tray 5, treat that broken sample places on the pallet 5, the start sample is unsettled, the resistance when alleviating electric motor starting, complete machine stability is good.
