The specific embodiment
Below in conjunction with embodiment, the utility model is elaborated.Wherein identical parts represent with identical Reference numeral.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric centre.
View in the safety guard of the conveyor screw Anti-blockage that Fig. 2 provides for the utility model during safety door sealing, Fig. 3 is the view of safety door while opening.The utility model embodiment provides a kind of safety guard of conveyor screw Anti-blockage; for conveyor screw; conveyor screw comprises hopper 2; on the sidewall of hopper 2, offer inlet point 1 and discharge port 5; hopper 2 inside are provided with S. A. 3; on S. A. 3, be fixedly connected with blade 4, please refer to Fig. 1, the structure of inlet point 1 and S. A. 3 and blade 4 is same as the prior art.Wherein, this safety guard comprises: be arranged on flash mouth 6 and safety door 7 on hopper 2 sidewalls, safety door 7 by rotating shaft 8 fixedly shutoff on flash mouth 6.
As shown in Figures 2 and 3, flash mouth 6 can be that the sidewall at hopper 2 picks out one section of short tube, at the opening part of short tube, utilizes vinyl cover or crown cap as safety door 7.Under normal conditions, safety door 7 passes through deadweight shutoff at flash mouth 6, preferably; safety door 7 passes through pinch device shutoff at flash mouth 6; pinch device can be the elements such as spring, and during conveyor screw work, safety door 7 is in closed condition; when discharge port 5 occurs to stop up; material in hopper 2 pushes hopper 2 inwalls, backs down safety door 7, and material overflows from flash mouth 6; thereby discharged pressure, protected conveyor screw.After handling the plugging fault at discharge port 5 places, safety door 7 returns to closed condition as shown in Figure 2.
