As Fig. 1, in embodiment shown in Fig. 2, the actuating device 1 of this malleation DWG is arranged on left end, inlet point 21 is arranged on hopper 2 right-hand member top, discharging opening 22 is arranged on hopper 2 left end bottom, when starting actuating device 1 and using, material constantly falls in hopper 2 from inlet point 21, left-turn spiral axle 31 and the synchronous opposite direction rotating of right hand helix axle 32, helicallobe 33 promotes material and moves to left, because the staggered coupling distribution of the helicallobe 33 on left-turn spiral axle 31 and right hand helix axle 32 is in " people " font, namely helicallobe interval is arranged, therefore drop in left-turn spiral axle 31 or right hand helix axle 32 pitch in the process that material moves to left, except being subject to the axial component of left-turn spiral axle 31 or right hand helix axle 32 helicallobe 33, be subject to the axial component of right hand helix axle 32 or left-turn spiral axle 31 helicallobe 33 simultaneously, can prevent material from sticking on screw shaft while of well-beaten, above discharging opening 22, discharging opening is fallen into until move to left.
In order to prevent overload, proterctive equipment, as further improvement of the utility model scheme, described inlet point 21 is also provided with valve and valve driving machine structure, also comprise electrical controller, electrical controller is electrically connected with actuating device 1, electrical controller is electrically connected with valve driving machine structure, described is just provided with pressure sensor and level sensor to hopper 2 inwall of inlet point 21, pressure sensor and level sensor are electrically connected with electrical controller, when pressure sensor and level sensor feedback information exceed predetermined value, electrical controller and by-pass valve control driver train valve-off, namely material stops supply, actuating device 1 continues emptying work, when pressure sensor and level sensor feedback information are in predetermined range, electrical controller by-pass valve control driver train opens valve, material continues supply, realization prevents blocking, overload.
Because helicallobe 33 exists certain interval in its axial direction and between hopper 2 inwall, in order to the shaft end preventing material from sticking in left-turn spiral axle 31 and right hand helix axle 32, as further improvement of the utility model scheme, as Fig. 3, shown in Fig. 4, hopper 2 inside panel of described inlet point 21 side axle head is fixedly installed two pieces pan feeding material scraping plate 24, two pieces pan feeding material scraping plate 24 is vertically arranged on directly over left-turn spiral axle 31 and right hand helix axle 32 respectively, its lower surface and the spacing between left-turn spiral axle 31 and right hand helix axle 32 outside face are free-running fit, hopper 2 inside panel of described discharging opening 22 side axle head is fixedly installed two pieces discharging material scraping plate 25, two pieces discharging material scraping plate 25 is vertically arranged on immediately below left-turn spiral axle 31 and right hand helix axle 32 respectively, its upper surface and the spacing between left-turn spiral axle 31 and right hand helix axle 32 outside face are free-running fit, and the material be attached on screw shaft can scrape by pan feeding material scraping plate 24 and discharging material scraping plate 25.
In order to prevent the hopper 2 inner cavity top adhesion wall built-up of material above discharging opening 22, as further improvement of the utility model scheme, above described discharging opening 22, hopper 2 inner cavity top arranges circular arc stock guide 23, can move down by the extruding of arc surface when material is pushed on circular arc stock guide 23, fall into smoothly in discharging opening 22, prevent adhesion wall built-up.
In order to prevent material adhesion further on the rotary shaft, as further improvement of the utility model scheme, as shown in Figure 5, the position that described helicallobe 33 and left-turn spiral axle 31 are fixedly connected with right hand helix axle 32 arranges the through hole of along the circumferential direction alternative arrangement, material is in course of conveying, material near lead to the hole site can move to the direction that service direction is contrary because of the thrust by helicallobe 33, flow into after in a rear joint pitch and promoted reach by the helicallobe 33 in a rear joint pitch again, namely the material near S. A. is kept in motion all the time, adhesion can be prevented on the rotary shaft.
Rotating to ensure that S. A. is stable in the process of transported material further, as improvement project of the present utility model, described left-turn spiral axle 31 and right hand helix axle 32 arranging drop-hanger bearing.
For the ease of observing the traffic condition of material in hopper 2 at any time, as further improvement of the utility model scheme, described hopper 2 arranges observation window.
This malleation DWG is fixedly connected on respectively helicallobe 33 on left-turn spiral axle 31 and right hand helix axle 32 because the measure-alike and staggered coupling distribution of spiral is in " people " font, drop in left-turn spiral axle 31 or right hand helix axle 32 pitch except being subject to the axial component of left-turn spiral axle 31 or right hand helix axle 32 helicallobe 33 in the process of therefore mass transport, be subject to the axial component of right hand helix axle 32 or left-turn spiral axle 31 helicallobe 33 simultaneously, the while of well-beaten, can prevent material from sticking on screw shaft; Because the pitch of helicallobe 33 on left-turn spiral axle 31 and right hand helix axle 32 increases gradually from inlet point 21 on discharging opening 22 direction, therefore can prevent material from transportation, blocking hopper 2, ensure continuative transport; Because left-turn spiral axle 31 and right hand helix axle 32 are all installed with transmission gear 34 near one end of actuating device 1, and two pieces transmission gear 34 intermeshes, and therefore ensure that the synchronous and reversing sense steady running of left-turn spiral axle 31 and right hand helix axle 32; Owing to being equipped with anticorrosion coating on hopper 2 inwall, left-turn spiral axle 31, right hand helix axle 32 and helicallobe 33 surface, therefore decay resistance is strong, long service life.
