Description

[Detailed Description of the Invention] Purpose of the Invention This invention relates to an improvement of the pestle attachment part of the pestle and mortar type crusher of the present invention, which maintains a good rotational balance during rotation of the pestle and improves the drive mechanism of gears, etc. The purpose is to prevent wear and tear and to ensure safety in inputting raw materials, etc.

BACKGROUND TECHNOLOGY As shown in FIGS. 4 to 6, a conventional rotary pestle-type grinding machine has a plurality of pestle attachment frames C mounted on a rotating shaft B that is inclined with respect to the mortar. stick protrudingly,
Currently, the punch attachment shaft A is detachably attached to each punch attachment frame C, but since the rotational resistance of each punch is constantly changing, the punch attachment shaft A is attached to each punch attachment frame C. The rotational balance is not uniform, which causes serious wear and damage to the drive gear of the rotating shaft B, and also causes damage to the punch mounting frame C, the punch retaining rod D, the grip E for attaching and removing the punch, etc. when the punch rotates. The protrusion caused a defect that caused work hazards, such as hitting the human body, especially the head, during the loading operation of raw materials, and catching hats and clothing.

Structure of the invention The present invention is an attempt to improve these defects, and includes an upper mounting disc and a lower mounting disc on a rotating shaft that is slightly inclined from the vertical at the upper part of the rotating mill. A punch mounting shaft equipped with a punch is attached to the upper and lower mounting disks, and the punch attachment rod is fixed to the upper and lower mounting disks, and the punch attachment rod and a grip for attaching and detaching the punch are placed between the upper and lower mounting disks at their periphery. The gist is that it is provided so that it does not protrude beyond the section.

To explain the embodiment of the present invention with reference to the drawings, a mortar 2 installed on a base 1 has a protective frame 3 on its outer periphery.
is provided and is formed to rotate at a low speed.

Further, a rotating shaft 6 is provided in the drive housing 5 at the upper part of the machine body 4 at a slight angle from perpendicular to the mortar 2, and an upper mounting disk 7 and a lower mounting disk are fixed to the rotating shaft 6. A plurality of fitting holes 10 each having a support shaft hole 9 and a cutout 10' are formed in the support shaft hole 8 in opposition to each other, and a punch mounting shaft 12 to which a punch 11 is attached is attached to the support shaft hole 9 and the fitting hole 10. The punch mounting shaft 12 is fixedly fixed to the upper mounting disk 7 by a punch fixing rod 13 provided so as not to protrude from its periphery.

A grip 14 for attaching and detaching the punch is attached to the punch mounting shaft 12 so as not to protrude from the periphery of the upper and lower mounting disks 7 and 8 when the punch is mounted, and the punch 11 is pressed against the inner surface of the mortar 2 as is known. It is energized to do so.

Since the embodiment of the present invention is constructed as described above, when rotating the punches 11, 11, etc., the upper and lower mounting disks 7, 8 rotate integrally with the rotation shaft 6, and the mortar 2. When removing the pestle 11, remove the pestle retaining rod 13, rotate the handle 14 for attaching and detaching the pestle, and align it with the notch 10'. 12 is pressed downward against the spring and pulled out downward.

Effects of the invention The present invention is a pestle-type grinding machine in which the mortar rotates, in which an upper mounting disc and a lower mounting disc are fixed to a rotating shaft provided at a slight inclination above the mortar, and the upper and lower mounting discs are attached to A punch attachment shaft equipped with a punch is attached and fixed with a punch attachment rod, and the punch attachment rod and a grip for attaching and removing the punch are provided between the upper and lower attachment disks so that they do not protrude from the periphery of the upper and lower attachment disks. The mounting disc of the part rotates smoothly to alleviate the imbalance of rotational balance that acts on the punch mounting part due to resistance changes during the rotation of each punch, and the rotating shaft rotates smoothly, driving the punch. The durability of the mechanism can be improved by preventing wear and tear on the gears, rotating shafts, etc., and the attachment part of the punch attachment shaft is not protruding like the conventional one due to the upper and lower attachment disks, and the punch attachment rod and Since the grip for attaching and detaching the punch is shielded, operations such as loading raw materials while the punch is rotating can be performed safely, which has excellent features and practicality.
