Fig. 1 is the structural scheme of mechanism of a kind of embodiment of the present utility model

Fig. 2 is the vertical view of sample collecting device 3 among Fig. 1.

The specific embodiment

The utility model is described in further detail below in conjunction with embodiment.

Automatic minute model machine shown in the figure, actuating unit 33 drives the belt pulley 23 that is arranged in the rotating shaft 32 by belt pulley 25, belt 26 and rotates, thereby make rotating shaft 32 rotate, the sprocket wheel 22 that connects in rotating shaft 32, cam 31, belt pulley 27 also rotate with rotating shaft 32 certainly.

Frame 10 is matrixes of whole automatic minute model machine, and hopper 1, tripper 2, sample collecting device 3, vibrator 4, actuating unit 33, rotating shaft 32 etc. are arranged on the frame 10.Hopper 1, vibrator 4, tripper 2, sample collecting device 3 are arranged in order from top to bottom.

Tripper 2 by tripper case 2-1, be connected the taper material distributing cap 2-2 of tripper case internal upper part, the aggregate bin 2-3 that is connected the tripper lower box part by three connecting rod 2-6 and form; The axis of taper material distributing cap 2-2, the axis of sample collecting device 3 overlap with tripper case axis 2-4.

8 passage 3-1 are arranged in the sample collecting device 3, and it is on the same round 3-3 in the center of circle that the import 3-2 of each passage is evenly distributed on the sample collecting device axis.

The outlet 2-5 of aggregate bin 2-3 bottom is above the import 3-2 of passage; The outlet of aggregate bin 2-3 is eccentric aggregate bin not on the axis of sample collecting device 3.

Vibrator case 4-1, be connected the taper material distributing cap 4-2 of vibrator upper box part, be connected the screen cloth 4-3 of vibrator case inside, the aggregate bin 4-4 that is connected the vibrator lower box part and form vibrator 4 by three connecting rod 4-6.The top that taper separates cap 4-2 is the discharging opening 1-1 of hopper 1; The below of the outlet 4-5 of aggregate bin 4-4 is that taper separates cap 2-2.Described screen cloth 4-3 becomes to removably connect with vibrator case 4-1.

Hopper cover 12 is covered on hopper 1 top; One projection 13 is arranged below hopper cover 12.Have and the corresponding recess 14 of this projection at the top of shaft 7.Shaft 7 top 7-1 stretch in the hopper 1 by outlet 1-1, and bottom 7-2 is tapered.Be connected with two stirring steel wires 15 that certain amount of deflection is arranged on the top of shaft 7.The spring 11 that is provided with between frame 10 and shaft, shaft 7 are under the effect of this spring, and the taper of its underpart is close to the outlet 1-1 of hopper; When covering hopper cover 12 on hopper 1, the projection 13 under the hopper cover 12 is pressed on the recess 14 at shaft 7 tops, and the active force that makes shaft 7 overcome spring 11 then moves down, and makes the tapered lower portion 7-2 of shaft and export between the 1-1 gap to occur.

The course of work of brief description present embodiment.

At first, 800 gram metal mining powder samples are carefully poured among the hopper 1; Cover hopper cover 12, hopper cover center projections 13 presses down, and shaft 7 is moved down, and the taper of shaft 7 bottoms and the outlet 1-1 of hopper 1 isolate certain interval.At this moment, actuating unit is started working.Shaft 7 rotates under sprocket wheel 20 drives, and shaft 7 drives the metal mining powder sample that stirs in 15 pairs of hoppers 1 of steel wire and stirs.

Because gravity effect metal mining powder sample falls naturally by the taper of shaft 7 bottoms and the gap between outlet 1-1.The metal mining powder sample falls into vibrator 4, after disperseing, the taper material distributing cap 4-2 on vibrator top falls on the screen cloth 4-3 earlier, whether screen cloth can to sneaking into foreign material in vibration processes in the sample, as come from loose thread on the work gloves, cleaning and check and sift out these foreign material with the cilium that comes off on the hairbrush etc., screen cloth also can be controlled the granularity of sample.Another effect of screen cloth is equivalent to the set of several little adjacent riffles, be to metal mining powder sample cutting apart again, between two parties.

Fall into the tripper 2 of rotation after the outlet 4-5 of the aggregate bin of the metal mining powder sample process vibrator lower box part after the screening is placed in the middle, because the outlet 2-5 of eccentric aggregate bin 2-3 makes circular motion above the import 3-2 of sample collecting device 3 interior eight passages, and the import 3-2 of eight passages evenly is arranged on the same circumference, and 800 gram metal mining powder samples are assigned in eight passages by five equilibrium.Outlet at eight passages of sample collecting device 3 is with the PE sample sack respectively, and the metal mining powder sample directly falls into eight PE sample sacks, will contain respectively in each PE sample sack into 100 gram metal mining powder samples, so far divides the sample process to finish automatically.
