Detailed description of the invention
Below embodiments of the invention are described in detail:
As shown in Figure 2, dust test chamber feeding device of the present invention, the one or more charge doors 20 including support 10, magazine 11, at least one-level hopper and communicate with dust test chamber, described magazine 11 is fixed on described support 10, the charging aperture of hopper described in chopped-off head communicates with described magazine 11, the discharging opening of hopper described in afterbody communicates with described charge door 20, and the discharge outlet of described hopper is provided with valve.
Feed in raw material to described hopper by described magazine 11, material joins dust test chamber from the discharging opening of hopper by charge door 20 again; The material adding dust test chamber from charge door 20 like this can realize linear reinforced, added material can cover the whole test face of dust test chamber, guarantee the uniformity of feeding in raw material, and material relies on the effect of gravity to enter dust test chamber, charging rate is even, further ensures for raising test fabric uniformity provides.Described material is sand or dirt.
In the present invention, multistage hopper can be adopted or only adopt a hopper.When adopting multistage hopper, the mode be flexible coupling can be adopted between adjacent two hoppers or adopt hardwired mode.It is described that be namely flexible coupling be adopt to link the flexible material such as film and connect; Accordingly, namely described Hard link is adopt the metal identical with described hopper material or plastics.This preferred embodiment is provided with one-level hopper 121 and secondary hopper 131, described magazine 11, described one-level hopper 121 and described secondary hopper 131 arrange from top to bottom successively and pass through to link film 30 and be communicated with, material, successively by described magazine 11, described one-level hopper 121 and described secondary hopper 131, enters dust test chamber finally by described charge door 20.
In the present invention, described charge door 20 is an elongated hole, or described charge door 20 includes multiple hole, and multiple hole linearly distributes, when making to feed intake, added material finally can shape into a line, whole test face can be covered, improve reinforced uniformity.Preferably, the sand dust amount that the aperture area of described charge door 20 adds as required regulates.
Described dust test chamber feeding device also includes guide rail 122 and drive unit (scheming not shown).Described support 10 is provided with fixed mount 101, and described fixed mount 101 can horizontally set, longitudinally setting or any direction be arranged.Described guide rail 122 is fixed on described fixed support 101, and described one-level hopper 121 is fixed with described drive unit, and described one-level hopper 121 is installed on described guide rail 122 slidably.Drive described one-level hopper 121 to slide along described guide rail 122 by described drive unit, one-level hopper 121 constantly vibrates, and sand dust is entered in secondary hopper 131 smoothly, avoids sand dust accumulate in one-level hopper 121 and block the discharging opening of one-level hopper 121.
Described one-level hopper 121 is identical with the structure of described secondary hopper 131, and the present embodiment is described for described one-level hopper 121.The discharge outlet of described one-level hopper 121 is provided with rotating shaft 124, and the length of described rotating shaft 124 and the length of described discharging opening adapt.The cross section of described rotating shaft 124 lacks shape for circle, and described rotating shaft 124 is connected with rotating shaft electric motor, and the discharging opening side of described one-level hopper 121 is provided with the hopper cambered surface 125 that the cambered surface that lacks with described circle coordinates, and the opposite side of described hopper cambered surface 125 is inclined-plane 126.Described rotating shaft electric motor drives described rotating shaft 124 to rotate, and when the cambered surface of described rotating shaft 124 and described hopper cambered surface 125 are fitted completely, described one-level hopper 121 is communicated with described secondary hopper 131, and material can pass through smoothly; When the cambered surface of described rotating shaft 124 and described hopper cambered surface 125 part are fitted, the plane that circle lacks and described inclined-plane 126 have certain angle, and described one-level hopper 121 is not communicated with described secondary hopper 131, and material can not enter secondary hopper 131; Certainly, also can regulate the fitting area of the cambered surface of described rotating shaft 124 and described hopper cambered surface 125, change the throughput of material.
Be provided with support member 21 between the discharging opening of described secondary hopper 131 and described charge door 20, described support member 21 is provided with through hole 22, and the discharging opening of described secondary hopper 131 is communicated by described through hole 22 with described charge door 20.
