Further, the described crossbeam of hanging is arranged on the middle and lower part of sealing screen box.
Further, the quantity of described vertical hold down gag is four or two, and evenly distributes.
Further, described vertical hold down gag comprises screw rod, backing plate and pressure strip, and backing plate and pressure strip are arranged on the lower end of screw rod, and screw rod and sieve nest top board are through being threaded.
Further, the quantity of described discharging opening is four to eight.
Further, described sieve door is the glass fiber reinforced plastic door or the metallic door of moulding.
The beneficial effect of the utility model is:
1, the utility model is a body structure of the sieve nest of dual-bin screen being made sealing, and the sieve lattice are arranged in the casing and with vertical pressure-tight mechanism and compress, and the body structure of sealing has been avoided pollutant entering sieve lattice such as extraneous dust; Guarantee the health of grain; Simultaneously can avoid material to raise outward, guarantee environmental sanitation, and form the material outer tunnel between the utility model sieve lattice and sealing screen box and the sieve door; Thereby do not increased the actual screening area that sieves lattice on the sieve lattice, improved screening effeciency if establish the material internal channel less.
2, the sieve nest of the utility model connects through hanging crossbeam, and is suspended on the frame through erecting by overhang, hangs the middle and lower part that crossbeam is arranged on sieve nest, and the center of gravity of whole dual-bin screen is reduced, thereby makes the dual-bin screen operation more steady.
3, the sieve lattice of the utility model are through being arranged on four vertical hold down gags and the sieve nest relative fixed on the sieve nest end face; Thereby avoid sieve lattice generation play in the dual-bin screen running; Avoid destroying the sieve lattice, guarantee the service life of sieve lattice, reduce the apparatus maintenance frequency.
4, the discharging opening of the utility model is provided with a plurality ofly, can choose one or more uses, handled easily wantonly in the actual use.
5, the utility model is novel in design, is skillfully constructed, and is simple in structure, easy to use, effective, can improve the production efficiency of dual-bin screen, guarantees the service life of dual-bin screen, reduces maintenance cost.
