    The invention relates to laboratory equipment, namely to the head of the laboratory vibratory chopper. one
    The purpose of the invention is to improve the efficiency of the grinding process.
    Figure 1 shows the head labrarator vibratory chopper, cross-section; figure 2 - the same, varint; on fig.Z - cylindrical disk heads laboratory shredder, side view; 4 and 5 of a cylindrical crucible scheme, variants; Fig, 6 - details of the head of the laboratory vibrator, disassembled; Fig.7 disk, top view; in Fig.8 is a laboratory vibratory grinder, a partial section; Fig.9 - the head of the laboratory vibratory chopper, another embodiment of the execution.
    The laboratory vibrator head contains a cylindrical crucible I with a lid 2 and a cylindrical disk 3 inside the crucible 1. The latter contains an outer casing 4 with an insert 5 and a sealing sleeve 6. Screw 7 secures the insert 5 at the bottom of the casing 4. The sleeve 6 can be attached to the casing 4 by any in a way. The liner 5 of the crucible between the bottom 8 and the inner side surface 9 has a mating annular surface 10.
    The disk 3 in the lower part has a corresponding annular chamfer 11 between the base 12 of the disk 3 and the cylindrical surface of the disk 13. The disk (FIG. 1) can slide onto the mating surface 10 during operation so that a space 14 forms under the disk, and the sample of the material to be ground is located in this area, is ground due to disk vibrations.
    The disk 3 on the upper edge has a stepped shoulder 15, which contributes to the grinding of larger rock samples. The cover 2 also includes a sealing ring 16 between the cover and the sleeve 6 so that dust is prevented from exiting the head.
    The crucible 17 (figure 2) is made of a whole piece of steel or other suitable material. The profile of the mating annular surface consists of two straight sections: the inner 18 and outer 19. Two beveled portions contribute to the sliding of the disk along the beveled (angular) surface of the crucible.
    In this construction, the disk 20 has a tapered through hole 21 in the direction of the disk axis, but offset from the disk axis, so that the walls of the hole taper in the direction from the larger diameter on the upper surface of the disk to the smaller diameter by. its bottom surface.
    When using the grinder of the proposed design for grinding a portion that has fallen into the cavity 22 under the disk, rock may be “pumped” through the hole 21 to the top of the disk, so that a continuous feed flow may occur for grinding through the hole 21.
    At some stages of grinding, a sample of the material may pass down through the opening, reaching the cavity 22 under the disk where the grinding takes place.
    Fine grinding of the sample material occurs between the surfaces 23 and 24, where there is close contact between the disk and the crucible, as well as the contact of the surfaces 25.
    The disk 26 (FIG. 3) has a somewhat conical base 27, the angle of which is conic forming approximately 3 ° with respect to the visible horizontal base of the cone. The annular chamfer 28 forms an angle of approximately 30 0 with respect to the lower surface of the disk 26.
    The outer surface 29 of the disk forms an angle of approximately 3 ° with respect to the visible vertical forming disk, so that in operation, when the conical base of the disk is installed somewhat horizontally, the side surfaces of the disk become parallel to the side surfaces of the crucible.
    The mating annular surface 30 (figure 4) forms an angle of 30 °. with respect to the bottom 31 of the crucible or 120 ° with respect to the side surface of the crucible 32.
    The mating annular surface (FIG. 5) between the bottom 33 of the crucible and the side surface 34 of the crucible includes an internal inclined section 35 located at an angle of 20 ° and an external inclined section 36 located at an angle of 30 °.

    Subject to change in angles.
    The laboratory grinder head contains crucible 37, disc 38 and $ cover 39. The latter has a recess 40, which includes clamping means when the head is in use. The disk 38 has an offset hole 39 and o
    step shoulder 41 for grinding larger rock samples. The crucible 37 has an internal inclined mating annular surface 42 between the inner surface 43 15
    and the bottom 44. The disk (Fig.7) contains a stepped bead 45 and a hole 46 passing through the disk in a position offset from the center of the disk. 20
    The laboratory grinder of FIG. 8 comprises a base 47 on which the head frame 50 is supported with the help of springs 48 and 49. The latter includes a pneumatic pressing 25 means 51, a clamping head 52 of a laboratory chopper between the pneumatic pressing means and a frame.
    The motor 53 is suspended to 30 frame 50, and the shaft 54, emerging from the motor, rests on bearings 55 and 56, between which a load 57 is hinged on the shaft 54 with a large eccentricity. 35
    Since the electric motor is mounted on frame 50 and at the same time it rotates an eccentrically secured load, the entire assembly vibrates on springs 49 and 48, causing the upward movement of the chopper head 52 and its orbital motion so that the disk inside the head moves in orbit and crushes and ground sample. 45
    Upon completion of the grinding, the pneumatic pressing means 51 is turned off and the head 52 can be removed from the shredder to remove the load. 50
    The crucible 58 (Fig.9) contains a curved inner mating annular surface 59 between the flat bottom 60 and the side surface 61.
    The disk 62 has a corresponding curved, 55th linear bottom chamfer 63. The curve contributes to the movement of the disk on the material in order to achieve a strong grinding action.
    . The proposed grinder head has a large grinding surface on the side surfaces and the bottom of the disk, which provides a good mixing action when rotating or moving the disk in orbit to capture the sample on the edge of the disk and the force effect under the disk. In a disc construction with a hole, the sample will eventually fall through the hole. Due to the continuous mixing action, every sample can enter the hole and undergo grinding. The sharp edge of the shoulder on the disk allows you to grind larger pieces of rock that usually accumulate on the top of the disk or ring in a disk or ring type grinder.
    The bottom of the crucible and disk are shaped so that the disk contacts the side and inclined mating ring surfaces, as well as part of the bottom to provide a large grinding surface, the hole, if present, can be located so that it is not above the center of the crucible and, therefore, when grinding, you can use the entire surface of the bottom.
