Description

Adjusting device of wet hammer crusher

Technical Field

The utility model relates to a breaker technical field, concretely relates to adjusting device of wet process hammer crusher.

Background

Hammer crushers are devices for crushing materials in an impact mode, a hammer head is driven to rotate through a driving main shaft through a motor generally, the materials are crushed by impact action after entering the crusher, the materials are crushed by the impact of a high-speed revolving hammer head, the crushed materials obtain kinetic energy from the hammer head and impact a counterattack plate at a high speed, meanwhile, the materials are mutually impacted and crushed for multiple times, and the materials after being crushed to reach a standard are discharged from the bottom.

Hammer crusher is when carrying out the breakage to the building stones, the tup rotates at a high speed and produces violent collision and friction with the building stones, building stones strike simultaneously and can also cause certain impact to the counterattack board after on the counterattack board, reach the certain time after using, wearing and tearing all can appear in tup and counterattack board surface, behind the tup surface wear, the whole length of quartering hammer shortens, the radius that leads to the rotation route when the quartering hammer rotates is less than the radius of original rotation route, can't satisfy original broken demand, lead to the broken efficiency of building stones to descend. Simultaneously, the inventor improves hammer crusher inside, sets up the abrasive sheet in the quartering hammer below, has the certain distance between abrasive sheet and the quartering hammer, and the building stones after being broken fall on the abrasive sheet, under the drive of quartering hammer, grinds on the abrasive sheet to the grit that makes the output has better grain shape. And also can cause wearing and tearing to the quartering hammer surface in the grinding process, lead to the quartering hammer surface in the hammer crusher of this application can be more serious than ordinary hammer crusher surface's quartering hammer wearing and tearing, and the wearing and tearing speed is faster.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem provide a wet process hammer crusher's adjusting device, can adjust the radius of the rotation route when rotating the quartering hammer behind the quartering hammer wearing and tearing.

The utility model provides a basic scheme: adjusting device of wet process hammer crusher, including quartering hammer regulation portion, quartering hammer regulation portion includes a plurality of discs, all set up a plurality of mounting holes different with disc centre of a circle distance on the disc, the mounting hole cover on a plurality of discs has cup jointed the dead lever, has cup jointed the quartering hammer on the dead lever between the disc.

The utility model discloses a principle and beneficial effect lie in: through set up a plurality of mounting holes on the disc, the mounting hole cup joints the dead lever, cup joints the quartering hammer on the dead lever between the disc. When the turning radius of the breaking hammer needs to be adjusted, the fixing rod penetrates through different mounting holes. The rotating path of the rotating hammer is equal to the length of the breaking hammer plus the distance between the circle center of the mounting hole and the circle center of the disc. When the quartering hammer surface is worn and torn, perhaps the wearing and tearing appear in the lapping plate surface, lead to the apart from between quartering hammer and the lapping plate to appear after the deviation, change the mounting hole that the dead lever was inserted, transfer the mounting hole to the mounting hole farther apart from the disc centre of a circle to compensate the distance between quartering hammer and the lapping plate.

Compared with the prior art, the distance between quartering hammer and the grinding plate can be adjusted, a plurality of mounting holes are formed, adjustment of different gears is met, after abrasion occurs on the surface of the quartering hammer or the grinding plate, the distance between the quartering hammer and the grinding plate is adjusted through adjusting the mounting position of the quartering hammer, and therefore the distance between the quartering hammer and the grinding plate is guaranteed to meet requirements.

Further, still include lapping plate adjustment part, lapping plate adjustment part includes lapping plate and the drive arrangement that the drive lapping plate goes up and down.

In addition to adjusting the mounting position of the breaking hammer, the position of the grinding plate may also be adjusted. After the grinding plate and the surface of the breaking hammer are abraded, when the distance between the grinding plate and the breaking hammer is adjusted, because the fixed rod is inserted into different mounting holes when the breaking hammer is adjusted, the positions of the mounting holes are fixed, the number of the mounting holes is limited, the distance between the breaking hammer and the grinding plate is adjusted by a plurality of gears during adjustment, and therefore the adjustment amount during adjustment is large. The grinding plate is adjusted through lifting of the oil cylinder or the screw rod, and therefore finer adjustment can be completed. Therefore, when the grinding device is adjusted, the distance between the breaking hammer and the grinding plate is roughly adjusted by adjusting the installation position of the breaking hammer, and then the distance between the breaking hammer and the grinding plate is finely adjusted by adjusting the height of the grinding plate.

Furthermore, a plurality of groups of mounting hole groups with the same arrangement mode are arranged on the disc.

The disc is provided with a plurality of groups of mounting hole groups with the same arrangement mode, namely a plurality of mounting holes with the circle centers equal to the circle center distance of the disc exist, when a certain mounting hole is worn, the mounting hole can be replaced by other mounting holes, and meanwhile, a plurality of breaking hammers can be mounted on the same radius. The arrangement modes of the mounting holes in the mounting hole groups on the disc are set to be the same, so that the positions of the holes on the disc are uniform, and the integral rigidity of the disc is ensured. The mounting hole is the screw thread formula and arranges, compares in the mode of radially arranging, can improve the scope of distribution, improves the precision of adjusting.

Furthermore, in the same mounting hole group, the centers of all the mounting holes are sequentially arranged along the Archimedes spiral.

The centre of a circle of each mounting hole is different with the distance of disc on the disc, because the quartering hammer sets up on the dead lever that passes the mounting hole, the length of quartering hammer is subtracted for the distance between disc centre of a circle and the grinding plate to the distance between quartering hammer and the grinding plate. When the length of quartering hammer is definite, with the dead lever setting on the mounting hole of difference to can adjust the distance between quartering hammer and the grinding plate, with the demand that satisfies different occasions. And after the surface abrasion of the breaking hammer leads to the reduction of the length of the breaking hammer or the surface abrasion of the grinding plate, the fixing rod can be arranged on the mounting hole which is farther away from the circle center of the disc, so that the compensation of the distance between the breaking hammer and the grinding plate is completed.

Furthermore, the distance between the circle center of the mounting hole in each group of mounting hole groups and the circle center of the disc is 190-250 mm, and the mounting holes between the hole closest to the circle center of the disc and the hole farthest from the circle center of the disc are uniformly distributed.

The utility model provides a plurality of mounting holes to distance adjustment between quartering hammer and the grinding plate, evenly arrange between hole and the hole, guarantee that each gear regulating variable is even.

Furthermore, the grinding plate is formed by splicing a plurality of arc-shaped plates, and the aperture of the through hole formed in a single arc-shaped plate is consistent.

The grinding plate is formed by splicing a plurality of arc plates with the same through hole diameter, so that a single arc plate can be replaced according to the demand of required stone materials, and the stone materials with different grain diameters can be output in the crushing process according to specific demands.
