[0035] By providing three sets of steel wire ropes 4, the pulley assembly and the hoisting drum 201, the three steel wire ropes 4 can be synchronously wound and released, and then the three connection points on the outer wall of the material discharge drum head 6 are synchronously lifted or lowered to avoid tilting of the material discharge drum head 6.

[0037] Specifically, if Figure 5As shown, the adjusting wheel group 9 includes an L-shaped bracket, a roller 902 and a large gasket 903. The bottom plate of the L-shaped bracket is connected to the platform plate 1 by bolts. The two rollers 902 are arranged horizontally opposite each other, and a circular arc groove is arranged in the middle of the roller 902, and the two circular arc grooves are rollingly clamped with a wire rope 4, and the axle of the roller 902 passes through the waist-shaped hole 901 on the vertical wall of the L-shaped bracket and is locked with a nut. The length direction of the waist-shaped hole 901 is opened in the vertical direction, and the two large gaskets 903 are passed through the screw section of the axle of the roller 902 and clamped on the vertical wall of the L-shaped bracket. By adjusting the height position of the two rollers 902, the length of the wire rope 4 between the first guide wheel group 8 and the second guide wheel group 10 can be adjusted, and then during the debugging stage, it is ensured that the horizontal setting of the unloading barrel head 6 will not tilt.

[0038] By setting the adjusting wheel group 9 between the first guide wheel group 8 and the second guide wheel group 10, the adjusting wheel group 9 can adjust the length of the steel wire rope 4 between the first guide wheel group 8 and the second guide wheel group 10, thereby ensuring that the useful running lengths of the three steel wire ropes 4 are strictly consistent and ensuring that the unloading barrel head 6 will not tilt. By opening the waist-shaped hole 901 on the vertical wall of the L-shaped bracket, the height position of the two rollers 902 can be adjusted.

[0039] In a specific embodiment of the present invention, Figure 1 and Figure 3 As shown, the telescopic shield tube 5 is in the form of an organ tube, and three threading rings 503 are evenly distributed on the outer circumference of the skeleton ring 501 of the telescopic shield tube 5, that is, the multiple skeleton rings 501 are arranged at equal intervals along the axis direction, and the skeleton ring 501 is covered with a protective cloth 502. The steel wire 4 passes through the threading ring 503, and the root of the threading ring 503 passes through the protective cloth 502 and is fixedly connected to the skeleton ring 501.

[0040] By arranging a threading ring 503 on the periphery of the skeleton ring 501 of the telescopic shield tube 5, and sleeved on the vertical section of the wire rope 4, the telescopic shield tube 5 can be guided to avoid the telescopic shield tube 5 from being deflected during the contraction process, thereby preventing the telescopic shield tube 5 from being blocked.

[0041] In a specific embodiment of the present invention, Figure 1 and Figure 4 As shown, the unloading barrel head 6 includes a core barrel 601 and a rubber barrel 602. The top of the steel core barrel 601 is connected to the telescopic shield barrel 5, and the two can be connected by a throat clamp.

The rubber barrel 602 is set as an umbrella skirt 603, and the umbrella skirt 603 includes a plurality of rubber strips cut along the axial direction.

[0042] Specifically, if Figure 1 and Figure 4 As shown, the root of the supporting leg of the movable pulley 7 passes through the rubber tube 602 and is welded to the outer wall of the core tube 601.

[0043] By setting a rubber tube 602 at the bottom of the core tube 601 as an anti-collision protection, the rust effect after contact with rainwater can be reduced; by setting the umbrella skirt 603 as a plurality of rubber strips that can be stretched outward, it is convenient for the dry powder material to overflow when stacking, increasing the radiation area of ​​the stacking and improving the unloading efficiency. The legs of the movable pulley 7 are welded on the outer wall of the core tube 601, the structure is strong and the operation is stable.

[0044] Working principle of the dry powder material unloader of the utility model: during the unloading process, the dry powder material is output from the high-end discharge port of the belt conveyor and enters the feed hopper, the feed hopper guides the material into the receiving top cylinder 102, and the dry powder material passes downward through the telescopic shield cylinder 5 and the discharge cylinder head 6, and is discharged to the material yard. As the height of the pile increases, the operator controls the reduction motor 3 to start through the remote control, the reduction motor 3 drives the winch shaft 2 to rotate, the three winch cylinder parts 201 synchronously retract their respective wire ropes 4, the wire rope 4 drives the movable pulley 7 to move upward, and then the discharge cylinder head 6 is lifted upward, the bottom of the telescopic shield cylinder 5 gradually begins to shrink together, and is stacked together through the threading ring 503 and the wire rope 4 guide. When the equipment is initially installed or undergoing maintenance, if it is found that the useful running length of the three steel ropes 4 deviates, causing the discharge barrel head 6 to tilt, the adjusting wheel group 9 can be adjusted by loosening the nut on the screw segment of the roller 902 axle and moving the two rollers 902 along the waist-shaped hole 901 to adjust the installation height. This can adjust the length of the steel rope 4 between the first guide wheel group 8 and the second guide wheel group 10 to ensure that the useful running lengths of the three steel ropes 4 are consistent, thereby restoring the discharge barrel head 6 to a horizontal state.

[0045] The utility model dry powder material unloader is connected between the receiving top cylinder 102 and the discharge barrel head 6 through a telescopic shield cylinder 5. The telescopic shield cylinder 5 provides closed protection for the dry powder material falling from top to bottom in the entire height range, effectively reducing the dust in the stacking process. Through the setting of the hoisting mechanism, it can achieve follow-up lifting along with the falling of the material, ensuring smooth stacking. The utility model dry powder material unloader uses a telescopic shield cylinder to protect the falling of the dry powder material and reduce dust. In addition, by directly installing a coaxial output reduction motor 3 on the hoisting shaft 2, transmission mechanisms such as belts, gears, and sprockets are no longer used, and the structure is more compact and more efficient. By setting three sets of steel wire ropes 4, the pulley assembly and the hoisting barrel part 201, the three steel wire ropes 4 can be synchronously wound and released, and then the three connection points on the outer wall of the discharge barrel head 6 are synchronously lifted or lowered to avoid the tilting of the discharge barrel head 6. Through the setting of the movable pulley 7, the lifting or lowering speed can be reduced. By setting an adjusting wheel group 9 between the first guide wheel group 8 and the second guide wheel group 10, the adjusting wheel group 9 can adjust the length of the steel wire rope 4 between the first guide wheel group 8 and the second guide wheel group 10, thereby ensuring that the useful running lengths of the three steel wire ropes 4 are strictly consistent and ensuring that the unloading barrel head 6 will not tilt. By opening a waist-shaped hole 901 on the vertical wall of the L-shaped bracket, the height position of the two rollers 902 can be adjusted. By setting a threading ring 503 on the periphery of the skeleton ring 501 of the telescopic shield tube 5, the threading ring 503 is sleeved on the vertical section of the steel wire rope 4, the telescopic shield tube 5 can be guided to avoid the deflection of the telescopic shield tube 5 during the contraction process, resulting in blocking. By sleeved a rubber tube 602 at the bottom end of the core tube 601 as an anti-collision protection, the rust effect after contact with rainwater can be reduced; by setting the umbrella skirt 603 as a plurality of rubber strips that can be stretched outward, it is convenient for the dry powder material to overflow outward when stacking, increasing the radiation area of ​​the stacking, and improving the unloading efficiency. The legs of the movable pulley 7 are welded to the outer wall of the core tube 601, so the structure has high strength and stable operation.
