Upper cone (10) is a reverse taper, and cone is manufactured with fish dace sieve plate.Upper cone (10) is arranged on tempering body (9)
Top.
Lower cone (13) is manufactured with fish dace sieve plate, and the top of lower cone (13) is connected with tempering layer B (12) bottom.Under
The bottom of cone (13) couples with II (60) that are flexible coupling on metric block II (58).
The course of work of the present invention：
Fallen into after the boosted machine lifting of grain in the cloth grain groove of hirudo leech, the vibration through cloth grain groove and multiple spot cloth grain, favorably
Enter the grain automatic classification problem that grain is produced in avoiding at 1 point.After grain enters drying layer, hot-air is heated to grain, and band
Walk moisture.The dry tenacity of drying layer is closely related through drying layer time length with grain.By controlling winding pipe enterprising
Air valve, can adjust the length of drying layer, and the drying tempering ratio of adjustable grain.Grain is dried through drying layer, tempering
Layer tempering, enter delivery hopper after drying, tempering again, then by being flexible coupling, into metric block I.Row's flow vector of metric block I can
Adjusted manually by adjusting rod I and metric block valve I, then adjust vibrating motor frequency, on-line control row's flow vector falls into grain
Deliver grain groove A.
Boosted machine is lifted into the upper cone of tempering body to grain again.Grain is from upper cone to the process for entering lower cone
In, the gentle breeze through multiple ventilating layers is dried and gentle breeze tempering, and subsequently into metric block II, through delivering grain, groove B is sent out.In metric block II
On, vibrating arm is installed.Vibrating arm is connected by vibrating head with metric block II and a point grain cone.Pass through vibrating motor, vibrating arm, vibration
Rod, point grain cone, make the grain in tempering body produce the knot doming effect of grain in flutter failure tempering body.The upper cone of tempering body and
Lower cone is manufactured with fish dace sieve plate, gentle breeze can be allowed to pass through.Multiple ventilating layers are provided with tempering body, by upper cone --- air intake
The rule arrangement of ventilating layer --- air draft ventilating layer ... air inlet ventilation layer --- lower cone, makes grain in movement from top to bottom
During, dried by gentle breeze and gentle breeze tempering is acted on, reach drying target.
