[0036] Furthermore, the pushing mechanism includes a fixed rod 106 fixed to the inner side of the cylindrical cavity 4 and a plurality of push rods 104 fixed to one side of each push plate 103 and movably extending to the inner side of the rotating drum 101.

The guide groove 108 includes an outer arc groove 1081, an inner arc groove 1082 and two reciprocating inclined grooves 1083 provided at one end of the fixed column 107. The two ends of the outer arc groove 1081 and the inner arc groove 1082 are smoothly connected by the two reciprocating inclined grooves 1083 (such as Fig.10 As shown), the outer arc groove 1081 is arranged at a side position close to the discharge port 6, and two support rings 115 (as shown) are fixed at both ends of the cylindrical cavity 4. Figure 4 As shown), the end of the fixing rod 106 is located inside the support ring 115, and the two ends of the drum 101 are rotatably connected to the two support rings 115 through balls;

[0037] Through the pushing mechanism, when the rotating drum 101 drives each transfer trough 102 to rotate close to the discharge port 6, the push plate 103 inside the transfer trough 102 can be moved toward the opening of the transfer trough 102, so that the alumina powder inside a transfer trough 102 close to the discharge port 6 can be pushed to the inner side of the discharge port 6, and the alumina powder inside the transfer trough 102 can be completely unloaded.

[0038] Further, the driving mechanism includes a first motor 111 installed on the inner side of the equipment bin, a worm gear shaft 110 rotatably connected to the inner side of the equipment bin, and two first driven pulleys 109 fixed to the two ends of the rotating drum 101. A worm gear 113 is fixed to the outer side of the worm gear shaft 110 at a position corresponding to the first motor 111. A worm 112 meshing with the worm gear 113 is fixed to the driving end of the first motor 111. Two first driving pulleys 114 are fixed to the two ends of the worm gear shaft 110. The two first driving pulleys 114 are respectively connected to the two first driven pulleys 109 through a first synchronous belt.

[0039] The driving mechanism is used to drive the drum 101 of the unloading mechanism to rotate at a constant speed, so that the aluminum oxide powder inside the box body 1 is unloaded outward at a constant speed to reduce the aluminum oxide powder from floating into the air.

[0040] Furthermore, the discharge extension mechanism includes a fixed discharge pipe 201 fixed at one end of the discharge port 6, an extended discharge pipe 202 is slidably connected to the inner side of the fixed discharge pipe 201, two threaded shafts 203 are movably provided at the upper and lower parts of the extended discharge pipe 202, two support plates 204 are rotatably connected to the two ends of the two threaded shafts 203, and two external threads in opposite directions are provided at the outer ends of the two threaded shafts 203, and two threaded sliders 205 are symmetrically rotatably connected to the outer ends of the two threaded shafts 203 through external threads in opposite directions, and two connecting rods 206 are symmetrically rotatably connected to the two sides of the four threaded sliders 205, one end of the four connecting rods 206 close to one side of the extended discharge pipe 202 is rotatably connected to the end of the extended discharge pipe 202, and one end of the four connecting rods 206 close to the fixed discharge pipe 201 is rotatably connected to the end of the fixed discharge pipe 201;

[0041] Through the unloading extension mechanism, when unloading, the opening of the extended unloading pipe 202 can be extended and close to the container below, which can reduce the contact area and contact time between the aluminum oxide powder and the air, thereby further reducing the dispersion of aluminum oxide powder into the air and further avoiding air pollution.

[0042] Furthermore, a second driven pulley 207 is fixed to one end of each of the two threaded shafts 203, and a second driving pulley 208 is rotatably connected to one side of a support plate 204 close to the second driven pulley 207. The second driving pulley 208 is respectively connected to the two second driven pulleys 207 through two second synchronous belts.

[0043] By rotating the second driving pulley 208, the second driving pulley 208 drives the two second driven pulleys 207 to rotate at an equal speed and in the same direction through two second synchronous belts, thereby driving the upper and lower threaded shafts 203 to rotate synchronously, thereby driving the extended discharge pipe 202 to move telescopically smoothly.

[0044] Furthermore, the knocking mechanism includes a second motor 301 installed at one end of the equipment bin, a reciprocating screw 302 is fixed to the driving end of the second motor 301, one end of the reciprocating screw 302 is rotatably connected to the other end of the equipment bin, and a bracket 304 is movably provided on the upper side of the reciprocating screw 302, a reciprocating slider 303 that can be adapted to the outer side of the reciprocating screw 302 is fixed on the lower side of the bracket 304, and a wheel axle 305 is rotatably connected to the two ends of the bracket 304, and two ends of the wheel axle 305 are fixed to the lower side of the partition 3 The two ends of the bracket 304 are slidably inserted with two guide rods 307, and the upper ends of the two guide rods 307 are fixed with a collision frame 308, and the lower side of the collision frame 308 is elastically connected to the bracket 304 through two impact springs 309. A plurality of downward pressing convex strips 310 are fixed to the outer side of the wheel shaft 305, and one side of each downward pressing convex strip 310 is provided with an inclined surface, and the other side of each downward pressing convex strip 310 is provided with a vertical surface, and the inner lower end of the collision frame 308 is rotatably provided with a roller 311;

[0045] Through the knocking mechanism, during unloading, high-frequency knocking can be performed on the lower side of the partition 3 inside the box body 1, so that the partition 3 produces high-frequency vibration. The high-frequency vibration can make the alumina powder material adhering to the upper side of the partition 3 fall off, so that the alumina powder can be completely poured out, thereby improving the unloading efficiency and further avoiding the waste of alumina powder material.

[0046] Furthermore, an isolation plate 402 is slidably connected to the inner side of the communication port 5, and a motor compartment 401 is provided at one end of the interior of the isolation plate 402 near the isolation plate 402. A third motor 403 is installed at one end of the inner side of the motor compartment 401, and a screw rod 404 is fixed to the driving end of the third motor 403, and the screw rod 404 is rotatably connected to one end of the isolation plate 402 through a thread.

[0047] The operation of the third motor 403 drives the screw rod 404 to rotate, and the rotation of the screw rod 404 drives the isolation plate 402 to slide from the inner side of the connecting port 5 to the inner side of the motor bin 401 through the thread, thereby connecting the cargo bin above the partition 3 with the cylindrical cavity 4 through the connecting port 5, making it convenient for the alumina powder to enter the inner side of the transfer trough 102 of the unloading mechanism through the connecting port 5.

[0048] Working principle: When in use, the alumina powder can be loaded on the inner side of the cargo hold located on the upper side of the box body 1. When unloading, the telescopic ends of the two lifting cylinders 7 are controlled to extend synchronously, and the telescopic ends of the two lifting cylinders 7 push the box body 1 to flip (such as Fig. 9 As shown), at the same time, the third motor 403 drives the screw rod 404 to rotate, and the screw rod 404 rotates to drive the isolation plate 402 to slide from the inner side of the connecting port 5 to the inner side of the motor bin 401 through the thread, so that the cargo bin above the partition plate 3 is connected with the cylindrical cavity 4 through the connecting port 5, so that the alumina powder can enter the inner side of the transfer trough 102 of the unloading mechanism through the connecting port 5;

[0049] When the box body 1 is flipped to a certain angle, the alumina powder in the cargo bin slides to the inner side of the box body 1 at one end where the unloading mechanism is located, and then the first motor 111 of the driving mechanism is controlled to drive the worm 112 to rotate, the worm 112 drives the worm wheel 113 to rotate, the worm wheel 113 drives the worm wheel shaft 110 to rotate, the worm wheel shaft 110 drives the two first driving pulleys 114 to rotate, the two first driving pulleys 114 respectively drive the two first driven pulleys 109 to rotate synchronously through the two first synchronous belts, and the two first driven pulleys 109 The drum 101 of the unloading mechanism is driven to rotate at a uniform speed, and the drum 101 drives the multiple transfer troughs 102 on its outer side to rotate. When each transfer trough 102 rotates to a position close to the connecting port 5, the sliding pin 105 in the pushing mechanism can slide into the inner side of the inner arc groove 1082, thereby driving the push plate 103 close to the connecting port 5 to move toward the bottom end of the transfer trough 102 through the two push rods 104, so that the alumina powder in the cargo bin can enter the inner side of the nearby transfer trough 102 through the connecting port 5. The rotation direction of the drum 101 is counterclockwise (such as Figure 7 As shown), after the inner side of each transfer trough 102 is loaded with alumina powder, it will rotate with the drum 101 from the position close to the connecting port 5 to the position close to the discharge port 6. At the same time, the sliding pin 105 of the pushing mechanism slides from the inner side of the inner arc groove 1082 through the reciprocating inclined groove 1083 to the inner side of the outer arc groove 1081, thereby driving the pushing plate 103 to move toward the opening of the transfer trough 102, so that the alumina powder on the inner side of a transfer trough 102 close to the discharge port 6 can be pushed out, and the pushed out alumina powder falls into the inner side of the discharge port 6. As the drum 101 of the discharge mechanism continuously rotates at a uniform speed, the alumina powder inside the box body 1 can be dumped at a constant speed, and the alumina powder will not be squeezed by the alumina powder accumulated on the inner side of the box body 1, so that the alumina powder at the outlet will not be subjected to excessive pressure and cause excessive speed, thereby effectively preventing the alumina powder from floating into the air, thereby reducing pollution to the atmosphere and reducing material waste;

[0050] In order to prevent the aluminum oxide powder inside the discharge port 6 from falling too far in the air, before dumping the aluminum oxide powder, the second active pulley 208 of the discharge extension mechanism is rotated, and the second active pulley 208 drives the two second driven pulleys 207 to rotate synchronously through two second synchronous belts, and the two second driven pulleys 207 respectively drive the two threaded shafts 203 to rotate synchronously. Since the outer ends of the threaded shaft 203 are symmetrically connected to two threaded sliders 205 through external threads in opposite directions, when the threaded shaft 203 rotates, it can drive the two threaded sliders 205 at both ends to move in the opposite direction. The two threaded sliders 205 move toward both ends, and the two threaded sliders 205 can drive the four connecting rods 206 to rotate. The four connecting rods 206 rotate at an angle perpendicular to the threaded shaft 203, so that the extended discharge pipe 202 can be pushed out from the inner side of the fixed discharge pipe 201, thereby extending the distance between the opening of the fixed discharge pipe 201 and the discharge port 6. When discharging, the opening of the extended discharge pipe 202 can be extended and close to the container below, which can reduce the contact surface and contact time between the aluminum oxide powder and the air, thereby further reducing the dispersion of the aluminum oxide powder into the air and further preventing the air from being polluted;

[0051] In order to prevent the aluminum oxide powder from adhering to the upper surface of the partition 3, when pouring, the second motor 301 of the knocking mechanism drives the reciprocating screw 302 to rotate. When the reciprocating screw 302 rotates, it can drive the reciprocating slider 303 adapted thereto to move back and forth at both ends of its outer side. The reciprocating slider 303 drives the bracket 304 to move back and forth, and the bracket 304 drives the wheel shaft 305 and the two friction rollers 306 to move back and forth. Since the friction rollers 306 are closely attached to the lower side of the partition 3, when the friction rollers 306 move along When the lower side of the partition 3 moves, the friction roller 306 itself can rotate through the friction force between the partition 3, and the friction roller 306 can drive the wheel shaft 305 to rotate, and the wheel shaft 305 drives the multiple downward pressing convex strips 310 to rotate. Since one side of each downward pressing convex strip 310 is provided with an inclined surface, and the other side of each downward pressing convex strip 310 is provided with a vertical surface, when the wheel shaft 305 moves from one end of the box body 1 to the end where the unloading mechanism is located, the rotation direction of the wheel shaft 305 is clockwise (such as Figure 8As shown in the figure, the wheel shaft 305 drives the plurality of downward pressing convex strips 310 to rotate clockwise. When the inclined surface of the downward pressing convex strip 310 contacts the roller 311, the impact frame 308 can be pushed downward by the roller 311. The impact frame 308 drives the two guide rods 307 to move downward and compress the two impact springs 309. As the wheel shaft 305 drives the plurality of downward pressing convex strips 310 to continue to rotate, when the inclined surface of the downward pressing convex strip 310 slides over the roller 311, the roller 311 is not supported by the downward pressing convex strip 310 and the inclined surface. When the axle 305 drives the multiple downward-pressing convex strips 310 to rotate continuously, the impact frame 308 can be driven to continuously impact the lower side of the partition 3, thereby causing the partition 3 to vibrate at a high frequency. The high-frequency vibration can cause the alumina powder material adhering to the upper side of the partition 3 to fall off, thereby allowing the alumina powder to be completely dumped out, thereby improving the unloading efficiency and further avoiding the waste of alumina powder material.
