The design of multiple collection bottles 23 is beneficial to the quantitative use of the fire - proof coating;

[0032] Furthermore, the mounting plate 21 rotates on the outer wall of the screw conveyor body 1 through a bearing. Card slots are evenly distributed on the upper surface of the mounting plate 21.

[0036] Further, there are two support rods 31 symmetrically distributed with respect to the screw conveyor body 1. The receiving plate 32 is used to receive the support rod 31. The receiving plate 32 and the bottom plate 33 are vertically arranged. The braking member 34 fixes the rotation angle of the support rod 31 to thereby fix the inclination angle of the screw conveyor body 1.

The universal wheels 331c are distributed at the four corners of the base 331b;

[0038] Further, there are four hydraulic cylinders 331a, which are distributed at the four corners of the bottom plate 33. The design of the four universal wheels 331c facilitates driving the overall mechanism to move. The base 331b and the bottom plate 33 are arranged in parallel.

[0039] The braking member 34 includes a grooved wheel 341 and a screw 342. The grooved wheel 341 is fixedly connected to the end of the support rod 31 far from the screw conveyor body 1. The grooved wheel 341 is connected to the receiving plate 32 through the screw 342;

[0044] Further, the feed hopper 12 is located at the bottom of the screw conveyor body 1, and machining a conical cavity in the feed hopper 12 is beneficial to introducing the fireproof coating into the screw conveyor body 1.

[0045] When this patent works, the fireproof coating is filled into the screw conveyor body 1 through the feed hopper 12, and the screw conveyor body 1 is used to transport the fireproof coating to the top of the goaf in the coal mine. The worker on the scaffold rotates the mounting plate 21, and the mounting plate 21 drives the threaded cylinder 22 to be directly below the discharge pipe 11. Subsequently, the bolt 243 in the ear plate 242 is inserted into the corresponding card slot in the mounting plate 21, thereby fixing the position of the mounting plate 21 on the screw conveyor body 1. The fireproof coating discharged from the discharge pipe 11 directly enters the collection bottle 23 through the threaded cylinder 22 for collection, preventing the airflow at the top of the goaf in the coal mine from blowing the fireproof coating away. When the support plate 32 rotates the support rod 31, the support rod 31 drives the screw conveyor body 1 to tilt. Subsequently, the screw 342 in the support plate 32 is inserted into the card slot of the grooved wheel 341, thereby initially fixing the tilt angle of the screw conveyor body 1. Subsequently, the reinforcing plate 352 is rotated on the outer wall of the fixing block 351, and the connecting head 353 and the limiting plate 354 are fixed by using the plug pin 355. Thus, a triangular structure is formed among the screw conveyor body 1, the reinforcing plate 352, and the bottom plate 33, increasing the stability of the screw conveyor body 1 when it tilts. The overall mechanism is moved by the universal wheel 331c, and the use height of the screw conveyor body 1 is increased by the extension of the output end of the hydraulic cylinder 331a on the base 331b.
