It is right-angled trapezium support plate with the 4th support plate (8), first support plate (4) and the 4th support plate (8) structure feature phase
Together.
6. a kind of gravel screening installation for building according to claim 1, which is characterized in that first screen drum (15),
Third screen drum (17), the 4th screen drum (26), the 5th screen drum (30), the 6th screen drum (31) are identical with discharge barrel (33) inner diameter size,
Second screen drum (16) is identical with the 7th screen drum (32) inner diameter size.
7. -6 any one a kind of gravel screening technique for building according to claim 1, which is characterized in that including walking as follows
It is rapid:
The charging of SS001 gravel, to the gravel for needing to screen is added in feed hopper (12), third motor (11) drives the first spiral
Flood dragon (18) rotation, the gravel in feed hopper (12) is delivered in the first screen drum (15) along feed pipe (13)；
SS002 carries out level-one screening to the gravel that needs screen, and first motor (9) drives the rotation of the second spiral flood dragon (20), will
Gravel in first screen drum (15) is delivered in the second screen drum (16), and first motor (9) drives roller (21) rotation, so that
Fixed block (23) stirs the gravel in the second screen drum (16), to promote the screening of gravel, falls from the first sieve pore (27)
Gravel can be fallen along first baffle (5)；
SS003 carries out second level screening to the gravel in the 5th screen drum (30), and the second motor (10) drives roller (21) rotation, to the
Gravel in seven screen drums (32) is stirred, so that gravel falls on (5) one surface of first baffle from the second sieve pore (34)
It falls again；
SS004 gravel screens final process, and the second motor (10) drives the 4th spiral flood dragon (35) and the 5th spiral flood dragon (36)
Rotation, the gravel after screening finally pass through discharge barrel (33) and fall, and complete the multistage screening processing of gravel.
