Abstract

The utility model relates to an air draft channel structure which comprises an air cylinder, an air draft channel and a fixed plate. The air draft channel is arranged on an opening at the lower end of the air cylinder, the fixed plate is arranged in the middle of the right end of the air cylinder, and a fan is arranged at the left end of the air cylinder. A wind shield I is installed at the right end of the air cylinder through bolts, and a wind shield II is fixed on the fixed plate through saucer-shaped bolts. A dynamic wind adjusting door is arranged on the upper portion of the air draft channel through hinges, an observing window is arranged on the lower portion of the air draft channel, and an adjusting rod is arranged on the dynamic wind adjusting door. The air draft channel structure is simple in structure, low in cost, good in using effect and capable of achieving dual-directional adjustment of air quantity.

Description

A kind of suction channel structure
Technical field
The utility model relates to grain (seed) and cleans processing technique field, relates in particular to a kind of suction channel structure.
Background technology
At present, grain (seed) is cleaned in process equipment a part of structure indispensable on suction channel, and the suction channel structure is also varied, and air channel structure commonly used is dull wind structure, but dull wind structure can not effectively be removed impurity, directly affects the effect of cleaning of cleaning process equipment.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, suction channel structure that result of use is good.
For addressing the above problem, a kind of suction channel structure described in the utility model, it is characterized in that: this structure comprises air duct, suction channel and fixed head; The lower ending opening place of described air duct is provided with described suction channel, and its right-hand member middle part is provided with described fixed head, and its left end is provided with blower fan; The right-hand member of described air duct is equipped with the deep bead I by bolt; Be fixed with the deep bead II by dish shape nut on described fixed head; Described suction channel top is provided with dynamic air register by hinge, and its underpart is provided with observation window; Described dynamic air register is provided with adjusting rod.
Have air inlet on described deep bead I.
Described deep bead II is semicircle.
The utility model compared with prior art has the following advantages:
1, be provided with adjusting rod owing to being provided with dynamic air register in the utility model, therefore, dynamically air register can be opened by adjusting rod; Simultaneously, can regulate the deep bead II by dish shape nut, thereby realize the bidirectional modulation air quantity.
2, the utility model is simple in structure, cost is low, and result of use is good.
Description of drawings
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is left view of the present utility model.
In figure: 1-air duct, 2-deep bead I, 3-fixed head, 4-dish shape nut, 5-suction channel, 6-adjusting rod, 7-observation window 8-dynamic air register 9-hinge 10-deep bead II.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of suction channel structure, this structure comprise air duct 1, suction channel 5 and fixed head 3.The lower ending opening place of air duct 1 is provided with suction channel 5, and its right-hand member middle part is provided with fixed head 3, and its left end is provided with blower fan; The right-hand member of air duct 1 is equipped with deep bead I 2 by bolt; Be fixed with deep bead II 10 by dish shape nut 4 on fixed head 3; Suction channel 5 tops are provided with dynamic air register 8 by hinge 9, and its underpart is provided with observation window 7; Dynamically air register 8 is provided with adjusting rod 6.
Wherein: have air inlet on deep bead I 2.Deep bead II 10 is semicircle.
During work, when material when suction channel 5 lower ends are flow through, under the suction of air duct 1 left end blower fan, impurity is discharged by the expansion chamber of air duct 1 left end through suction channel 5 under the effect of air-flow, and when air quantity is excessive, when finding to have material to be inhaled into suction channel 5 by observation window 7, first unclamp dish shape nut 4 rotation deep bead II 10 and unload wind, get final product fastening dish shape nut 4 if find to have material to be inhaled into suction channel 5 by observation window 7; If find to also have material to be inhaled into suction channel 5, this moment, slowly rotary regulating lever 6 was opened dynamic air register 8, carried out secondary and unloaded wind, until do not have material to be inhaled into suction channel 5.
