Fig. 2 is the casting of the utility model positive structure diagram of Sand screen.

Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.

Please continue to refer to Fig. 1, and as shown in connection with fig. 2, a kind of casting Sand screen of the utility model, including rack 10, vibrating motor 22 and the husky frame 30 of sieve, the quadrangle for sieving husky frame 30 is connected by vibrating spring 20 with the rack 10, described Vibrating motor 22 is installed in the rack 10 and is connected with the husky frame 30 of the sieve, and husky 30 side of frame of the sieve is equipped with feed inlet 31, rack 10 described in the side of the feed inlet 31 is equipped with particle mouth, is installed with pedestal 32, the pedestal at the particle mouth It is provided with shaft 33 on 32, particle rake 34 is uniformly provided in the shaft 33.

In use, casting is husky to enter feed inlet 31 by particle mouth by conveyer belt or carrier chain, volume is biggish in casting sand On the one hand block is crushed under the action of shaft 33, on the other hand, can also harrow 34 due to the particle in shaft 33 and make Under, so that block crushes the graininess in small volume, to guarantee that entering the casting sand volume sieved in husky frame 30 is unlikely to It is excessive, it influences it and sieves husky effect.

A kind of casting Sand screen of the utility model utilizes vibration by the way that vibrating spring 20 is arranged in rack 10 Motor 22, which drives, sieves the husky movement of frame 30, to increase the vibration frequency and amplitude of sieving husky frame 30, and is arranged in the side for sieving sand frame 30 Feed inlet 31 is rotated using the shaft 33 on pedestal 32 by the way that pedestal 32 is arranged at particle mouth, passes through volume particle in shaft 33 Rake 34 punctures the part large volume casting sand of charging to realize, is lowered into the casting Sha Tiji sieved on husky frame 30, mentions High its is to sieve husky effect.

Please continue to refer to shown in Fig. 2, driving motor, driving motor and shaft are also installed in the rack 10 of the utility model 33 are rotatedly connected.And be equipped in the bottom for sieving husky frame 30 and carefully go out husky bucket 40, to realize that sieving husky desired casting sand to satisfaction exports.

Further, the utility model is also equipped with filtering mesh at thin 40 tops of struggling against husky out, so that realization is to the two of casting sand Secondary filtering.

The sieve sand frame 30 of the utility model includes sieving husky net and fence board, and fence board is disposed around the periphery of the husky net of sieve, thus Casting sand is avoided to leak.Meanwhile the utility model is equipped with a window, and a hinged baffle on fence board, gear also on fence board Plate is located at window.Not filtrable particle output may be implemented by window, when not in use, using baffle, prevent casting husky It leaks in vibration.

In order to guarantee to sieve husky effect, the vibrating motor 22 of the utility model is two, and two vibrating motors 22 are symmetrically installed In the two sides for sieving husky frame 30.

And for the ease of the vibrated rear outflow of bulky grain sand, the rack 10 of the utility model and ground are at 10--15 ° of angle.

The casting Sand screen of the utility model, it is simple and practical in structure, it is vibrated by vibrating motor 22, sieves sand sand grains Not easy to stick stifled when sand leakage, and sand leakage is high-efficient, the grains of sand are not easy to stick stifled, and molding sand utilization rate is up to 95% or more.The device is durable, Not easy break-down, easily self-control and maintenance, every can save the sieve sand equipment investment of 1500--2200 member or so foundry sand and dimension Accomplish this.

The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
