Description

Senior processing equipment {A stone processing apparauts}

In the present invention, natural stone, which is relatively bulky and heavy, is put together with water in a polygonal rotating cylinder, so that when the rotating cylinder rotates, the natural stones collide with each other and rotate with the inner wall of the rotating cylinder. As for the chief processing device to process,

More specifically, the structure of the chief processing device known as Utility Model Publication No. 89-7875 of the present applicant and the heavy rotating cylinder buffer roller known as Utility Model Registration No. 112824 is improved.

The senior family factory of Utility Model Publication No. 89-7875 uses a free fall force applied by a plurality of rod protrusions welded in the longitudinal direction to the inner wall surface of the grinding chamber to grind and polish the natural stone. In order to absorb the impact, the guide roller is installed on the fluidized plate with the pin as a starting point so as to be in contact with the ring-shaped guide rail on the outer wall of the rotary cylinder, and the compression coil spring is mounted on the lower support shaft of the fluidized cylinder. It was designed to be able to rotate smoothly while maintaining the horizontal state of it, but it was to be able to rotate smoothly with only the compression coil spring, but it was designed to absorb and cushion tens of tons of shock with only the compression coil spring. High maintenance and repair cost due to shortening cycle of shock absorption and shock absorbing means including compressed coil spring There was this lifting issue.

Utility model registration No. 112824 has the structure of the heavy-duty cylinder buffer roller in order to absorb the shock load generated during the rotation of the rotary cylinder by the roller sliding with the ring-shaped guide rail of the rotary cylinder. Install the base nut and tightening nut on the support bolt of the base so that the support bolt of the base can be supported by the support plate through the four corners and the flow plate and shaft that was compressed with the compression coil spring. It was concluded.

However, the flow plates on both sides of the lower side as well as the lower side of the ring-shaped guide rails are supported by compression coil springs, so they have a shock absorbing effect. In other words, the balance of the rotating cylinder was lost due to the slack on both sides, and due to the eccentricity of the rotating cylinder, the frictional state between the ring guide rail and the roller was also uneven, causing vibration of the rotating cylinder, and their life cycle. As a result of shortening, the maintenance and repair costs are not only high, but also the operation rate of the senior processing apparatus is lowered, thereby lowering productivity.

In the case of Utility Model Publication No. 89-7875, a circular rod protrusion is fused to the inner wall of the rotating cylinder, and a "∧" shaped reinforcement tank is fused to the outer wall, so that the action of dropping the natural stone introduced into the rotating cylinder is insufficient. In addition to the lack of strength reinforcing effect of the outer wall, there was also a problem such as difficult to repair when the wall portion of the rotary cylinder is damaged.

The present invention solves all the problems of the prior art bar, the present invention is to effectively reinforce the strength of the rotary cylinder itself, excellent polishing performance, can effectively buffer the impact load of the rotary cylinder is safe, The technical challenge is to provide a senior factory that can reduce the wear and tear of frictional rotating parts and reduce maintenance and repair costs.

In the present invention, as illustrated in FIGS. 1 to 5, ring guide rails 12, 12 ′, and 12 ″ are formed at both ends and the middle of the polygonal rotary cylinder 10. Three sprocket wheels fixed to the rotary shaft of the drive motor, which is not shown in the drawings, and a driven sprocket wheel 14 connected to the electric chain is fixed to one end of the central shaft 16, and a rotary cylinder rotated by the drive motor Ring guide rails (12), (12 '), (12 ") of the (10) and two rollers (22) rotating in friction with friction are supported by the saddle (20) for rotation. The center of the 20 is pivoted to the hinge 24 of the flow plate 22 with a pivot 26, anchor bolts 30 fixed on the base 28 penetrates the four corners and anchor bolt 30 In the support plate 34 whose height is adjusted by the nut 32 fastened to the c) and the compression coil spring 36 is mounted between the flow plate 22,
