Abstract

The utility model discloses a high efficiency stone disintegrating machine for producing sand, and the inner wall of the shell body of the stone disintegrating machine for producing sand is provided with an impact plate. The lower end of the impact plate is provided with an impact block, and the shell body of the stone disintegrating machine for producing sand is provided with a regulating screw wire connected with the impact block. The lower part in the shell body of the stone disintegrating machine for producing sand is provided with a hexagonal strip-shaped screen plate, and the both ends of the shaft bearing of the main shaft of the stone disintegrating machine for producing sand are provided with compression type nonmetal contact seals. The both heads of an impact hammer are provided with hammer heads with the same shape, and the hammer heads of the both heads of the impact hammer are both provided with arrangement holes. The high efficiency stone disintegrating machine for producing sand has the advantages of high work efficiency and long service life, and the crushing ratio can reach above 1: 40. The stone material almost achieves to the needed crushing particle degree before entering into the screen plate.

Description

Efficient sand shaker

The utility model relates to a kind of sand shaker.

At present, sand shaker of the prior art, its shortcoming is: sand shaker is when making sand grains, mainly be by between the impact hammer of sand shaker and the sieve plate to the bump of processed building stones, it is pulverized, if once building stones can not be smashed sand grains less than the hole diameter of sieve (perforated) plate, but must behind multiple impact, just can finish, so not only prolonged process time, but also cause the high speed wearing and tearing of impact hammer, sieve plate and hole diameter of sieve (perforated) plate, and building stones also are easy to the sieve plate hole plug, thereby cause sand shaker to work; In addition, the impact hammer of existing sand shaker is owing to all be the version that adopts hammer handle and tup, after the tup wearing and tearing, have only and prolong the distance of tup by installing hole is extended, though this method has solved the clearance issues between tup and the sieve plate, but because the minimizing of tup quality and the modification of installing hole, make impact effects reduce greatly, its working (machining) efficiency is lower; Also have, existing sand shaker generally all is to adopt the malthoid sealing, is difficult to prevent that dust from entering in the bearing, so its bearing is easy to damage.

The purpose of this utility model is: the efficient sand shaker that a kind of high efficiency, long service life are provided.

The utility model is to constitute like this: it is to improve to form on the basis of original sand shaker, it comprises sand shaker (1), crash panel (2) is installed on the inner walls of sand shaker (1), in the lower end of crash panel (2) impact block (3) is housed, the set screw (4) that is connected with impact block (3) is housed on the housing of sand shaker (1), bottom in sand shaker (1) housing is equipped with hexangle type strip sieve plate (5), the nonmetal contact sealing of compression (7) is housed at the two ends of sand shaker (1) main shaft bearing (6), at two of impact hammer (8) the identical tup of shape is arranged, installing hole (9) is all arranged on the tup at impact hammer (8) two.

Owing to adopted technique scheme, the utility model is compared with existing sand shaker, has the advantage of high efficiency, long service life.The utility model is when work, after its processed building stones enter from hopper, just the impact hammer that is rotated (8) is beaten to crash panel (2), make it broken in advance, and then impact hammer (8) continues the building stones after the fragmentation are beaten to impact block (3), can pass through set screw (4) because of the distance between impact block (3) and the tup regulates, thereby stone powder is broken to required granularity, so not only increased the ratio of reduction to building stones, its ratio of reduction can reach more than 1: 40, but also make building stones before entering sieve plate, just realize almost meeting the requirements of particle size after cracking, thereby the wearing and tearing of sieve plate have been reduced widely, because the grating cross sectional shape of the utility model sieve plate (5) is a hexagonal configuration, this not only helps pulverizing building stones, but also helps dropping out of building stones, there is not clogging, after even grating may wear to a certain degree, the distance between the grating still remains unchanged, and has controlled the granularity of sand grains effectively; After the tup wearing and tearing of impact hammer (8), its reverse side can be installed or reverse end for end to install and continue to use; In addition, bearing of the present utility model (6) two ends are owing to adorned the nonmetal contact sealing of compression (7), this sealing almost reaches fluid-tight degree, enters the problem of bearing thereby solved dust effectively, thereby the utlity model has the advantage of high efficiency, long service life.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the A-A partial structurtes cross-sectional schematic of accompanying drawing 1;

Accompanying drawing 3 is the schematic diagram of the utility model impact hammer (8).

Embodiment of the present utility model: sand shaker (1) preferably adopts the fabricated structure that is divided into second from the bearing block center, and when making, the higher crash panel (2) of intensity that lastblock is made of steel is installed on the inner walls of sand shaker (1), load onto the impact block (3) that steel are made in the lower end of crash panel (2), on the housing of sand shaker (1), load onto a set screw (4) that is connected with impact block (3), the cross sectional shape that its grating is installed in bottom in sand shaker (1) housing is the strip sieve plate (5) of hexangle type, load onto the nonmetal contact sealing of compression (7) at the two ends of sand shaker (1) main shaft bearing (5), the nonmetal contact sealing of this compression (7) can adopt the finished product of selling on the market to assemble, two of impact hammer (8) is made into the identical tup of shape, and on the tup at impact hammer (8) two, all makes an installing hole and (9).
