Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.
Embodiment 1 an anti-blocking device for screw conveyer
As shown in fig. 1, the utility model provides an anti-blocking device for a screw conveyor, which comprises a material conveying pipe 1, wherein the material conveying pipe 1 is horizontally arranged; a feed inlet 4 is formed in one end of the feed delivery pipe 1, and an opening of the feed inlet 4 is upward; the other end of the conveying pipe 1 is provided with a discharge port 5, and the opening of the discharge port 5 is downward;
a spiral conveying rod 2 is arranged in the conveying pipe 1; one end of the spiral conveying rod 2 is in transmission connection with a motor 3, and the motor 3 is fixedly arranged at one end, close to the feed inlet 4, of the conveying pipe 1;
the bottom of the pipe wall of the material conveying pipe 1 is fixedly provided with an inclined groove body 6 along the axial direction, the inclined groove body 6 and the axial line of the material conveying pipe are arranged at a certain angle β, the angle β value is determined according to the material characteristics, and the angle β value is 2-15 degrees in the embodiment.
The inclined trough body 6 and the pipe wall of the material conveying pipe 1 form a closed cavity; the inclined groove body 6 is arranged between the feeding hole 4 and the discharging hole 5, and the lower end of the inclined groove body 6 is communicated with the discharging hole 5; the high end of the inclined groove body 6 is sealed.
A plurality of discharge openings 7 are formed in the bottom of the pipe wall of the material conveying pipe 1 corresponding to the inclined groove body 6; the plurality of discharge openings 7 are axially and uniformly arranged at intervals; a certain distance a is arranged between two adjacent discharge openings 7, and the distance a in this embodiment is 100-200 mm.
