Technical field

The utility model is related to a kind of construction equipments, more specifically, it is related to a kind of automatic sand sieving machine.

Background technology

It at present in fields such as sand, coals, needs to separate in the block of bulky grain and powder, be made using artificial riddler strong Degree is big, efficiency is low, and is often sieved to wet sand unclean, causes prodigious waste.

It is husky that the Chinese utility model patent that Authorization Notice No. is 206184752 U of CN in the prior art discloses a kind of sieve Machine, including rack and steel mesh, are connected between the rack and steel mesh by elastic component, and the gantry rotation has drive rod, The drive rod is connected with the push plate for being contradicted with grit, and the push plate is placed in rack back to the side of steel mesh, described Drive rod rotation drives push plate to be moved back and forth along the width direction of rack, if the side of the steel mesh back to push plate is fixed with Dry vibrating motor.

But the sieve of this sand sieving machine is fixedly connected with supporting rack, when sieve occurs damaged or needs the sand screened When precision difference, sieve trouble is replaced.

Utility model content

In view of the deficienciess of the prior art, being convenient for changing the automatic of sieve the purpose of this utility model is to provide a kind of Sand sieving machine.

To achieve the above object, the utility model provides following technical solution：A kind of automatic sand sieving machine, including rack and The Sand screen being arranged in rack is provided with the drive component for driving the Sand screen movement, the sieve sand in the rack Device includes the husky frame of sieve being arranged above rack, will sieve the sieve being arranged in the bindiny mechanism and the husky frame of sieve that husky frame is connect with rack Net, the Sand screen further include that the fixed mechanism for being used for fixing the sieve on the husky frame of sieve is arranged, and are arranged in the rack There are the fixed block being connect with fixed mechanism, the fixed mechanism to include the screw rod being threadedly coupled with fixed block and rotated with screw rod The fixed link of connection.

By using above-mentioned technical proposal, when fixed link is vertical with the husky frame side of sieve, sieve can be held, it is made to drive It will not fall off under the drive of component.When requiring replacement, rotate fixed link, make its from the state side vertical with side be it is parallel State, at this time sieve be just detached from the husky frame of sieve without the support of fixed link and be removed；When installation, it is husky that sieve is first put into sieve On frame, then rotating fixing rod, the state for keeping it parallel with side become vertical state, and sieve is fixed bar and holds not at this time It can fall off.The replacement and installation of sieve are realized by rotating fixing rod, it is easy to operate simple.

The utility model is further arranged to：Through-hole is provided in the fixed link, and the radius of through-hole is more than the half of screw rod The bottom end of diameter, the screw rod is provided with limited block, and the radius of limited block is more than the radius of through-hole.

By using above-mentioned technical proposal, what fixed link can be random rotates in the bottom end of screw rod, and because limited block Barrier effect will not fall off from the bottom end of screw rod, facilitate the rotation of fixed link.

The utility model is further arranged to：The side setting that the rack is contacted with fixed link is fluted, and groove Width is more than the width of fixed link.

By using above-mentioned technical proposal, fixed link can not rotate after coordinating with groove, place what sieve sand generated in the process Vibrations make the position of fixed link change the case where being fallen so as to cause sieve.Increase the stability of work.

The utility model is further arranged to：The limit for preventing limitation sieve from rising always is provided on the inside of the rack Plate.

By using above-mentioned technical proposal, the upper and lower surfaces of sieve are clamped with fixed link respectively for limiting plate so that sieve It will not up and down be shaken because fixed unstable during exercise, further increase the stability of work.

The utility model is further arranged to：The both sides of the rack and be provided with below the limiting plate clamping plate and Elastic component in clamping plate and rack interlayer is set.

By using above-mentioned technical proposal, clamping plate and elastic component can clamp the sieve of different in width, increase the husky frame of sieve The type for coordinating sieve, increases the flexibility of screening.

The utility model is further arranged to：The both ends of the rack can be provided with rubber with the contact surface of screen contact Pad two.

By using above-mentioned technical proposal, rubber pad two can play a buffering in the shaking before and after sieve, Reduce the service life that sieve improves sieve and the husky frame of sieve with damage caused by the reciprocating collision of the husky frame of sieve.

The utility model is further arranged to：Side of the husky frame of the sieve far from the driving component is provided with discharge bucket, The side of residing discharge bucket is provided with discharge component.

By using above-mentioned technical proposal, the larger sand in remaining aperture on sieve, during screen movement from Discharge bucket enters in discharge component.The convenient recycling to clout.

The utility model is further arranged to：The discharge component includes discharge bucket side setting roller frames, in roller frames The Material collecting box for harvesting placed on the roller and roll shaft of setting.

By using above-mentioned technical proposal, Material collecting box for harvesting is placed on roll shaft, the convenient moving operation to Material collecting box for harvesting.

In conclusion the utility model has the advantages that：The utility model is convenient to replace sieve, and energy It enough places different size and returns a sieve, while the clout not being screened out can be collected.
