Thus, the sand and stone left above the net-shaped end face 11 after being screened by the net-shaped end face 11 can automatically slide along the inclined net-shaped end face 11, and the sand and stone is prevented from remaining on the net-shaped end face 11, so that the meshes of the net-shaped end face 11 are blocked.
Preferably, a material receiving groove 14 is arranged at the bottom of the net-shaped end surface 11 along the extending direction of the net-shaped end surface 11. The material receiving groove 14 can collect the sand and stones which automatically slide down along the inclined net-shaped end surface 11, so that workers can carry the sand and stones conveniently.
Referring to fig. 2, as an embodiment of the present invention, the material sieving device further includes a filter sieve 3; the filter sieve 3 is arranged in the cavity 12 and positioned between the sand inlet channel 13 and the screen structure 2, and the filter sieve 3 is used for filtering sand and stones directly thrown into the cavity 12 from the sand inlet channel 13. The filter sieve 3 can play a role in filtering sundries. For example, when the screening device is used for separating silt in mud, impurities contained in the mud can be filtered by the filter screen 3, and workers only need to clean the filter screen 3 regularly or irregularly.
As an implementation manner of the utility model, the screening device further comprises a recycling bin which is arranged below the screen structure 2; be provided with the reposition of redundant personnel door on sieve material platform 1, after the reposition of redundant personnel door is opened, cavity 12 and the collection box intercommunication that is located 2 tops of screen cloth structure to let the gravel and sand that is located 2 tops of screen cloth structure directly get into in the collection box. When the screen structure 2 is used for carrying out normal separation and screening work on sand and stones, the recovery box can recover residual mixtures (such as water, silt and the like) falling from the meshes of the screen structure 2; when the screen structure 2 is blocked, the excessive sand and stone are deposited above the screen structure 2, and the sand and stone deposited above the screen structure 2 can be discharged into the recovery tank by opening the shunt door. The siltation can effectually be prevented to the top of screen cloth structure 2 by the design of reposition of redundant personnel door for sieve material device has better practicality.
Wherein, according to the kind difference of gravel and sand, can change different collection boxes or place different charging boxes in the collection box.
The utility model also provides a sieve material method, the sieve material method that this embodiment provided adopts above-mentioned arbitrary sieve material device to separate the screening to the gravel and sand of not unidimensional size, and this sieve material method includes:
dropping the sand and stone to be screened from the net-shaped end surface 11 of the screening platform 1, wherein the sand and stone with the size smaller than the meshes of the net-shaped end surface 11 can fall into the cavity 12 of the screening platform 1 from the meshes so as to screen the sand and stone with the size larger than the meshes of the net-shaped end surface 11, and the sand and stone falling into the cavity 12 falls on the net-shaped structure so as to carry out secondary screening on the sand and stone by the net-shaped structure;
in sand and stone that will treat the screening drops into cavity 12 from advancing husky passageway 13, sand and stone on screen structure 2, and screen structure 2 can separate the screening to sand and stone, and the sand and stone that the size is less than the mesh of screen structure 2 just can drop to the below of screen structure 2 in the mesh to select the sand and stone that the size is greater than the mesh of screen structure 2.
