[0012] Advantages of this invention: 1. This invention, by setting up a fixed box, baffle and limiting block, can limit the grab bucket mechanism containing raw materials in the box composed of the fixed box and baffle, support the grab bucket mechanism and prevent it from shaking or tilting when moving. At the same time, it can collect the raw materials that leak from the grab bucket mechanism and prevent the raw materials from falling on the moving path of the unmanned grab bucket crane, thus preventing environmental pollution and waste of raw materials.

[0013] 2. This invention, by incorporating a first transmission gear, a rotating rod, and a pipe, drives the scraper to reciprocate as the grab mechanism moves. This pushes material leaking from inside the grab mechanism, which is received at the bottom of the fixed box cavity, towards the two discharge heads, where it falls onto the conveyor belt surface. It then falls into the conveyor through the discharge pipe and is conveyed upwards by a screw conveyor. Material leaking from inside the conveyor is then discharged into a storage bin through the discharge pipe. When the grab mechanism reaches the grab position, the overhead crane body stops moving. At this time, the output of the first servo motor drives the first lead screw to rotate, causing the first slider to push the push column and the moving plate, thus enabling the second… The side plate moves the fixed box away from the grab bucket mechanism, and at the same time, the extension end of the electric telescopic rod moves the baffle away from the grab bucket mechanism. Then, the crane body drives the grab bucket mechanism to move down. At this time, the grab bucket mechanism pulls the bottom end of the pipe down. Before discharging the material, the switch valve is opened, so that the leaking material inside the storage box falls into the pipe through the switch valve and then falls to the discharge position through the bottom end of the pipe. Then the switch valve can be closed, the pump is started, and pressurized gas is introduced into the pipe, thereby pushing the leaking material inside the pipe to be discharged. This not only collects the leaking material during the movement of the grab bucket mechanism, but also discharges the collected leaking material to the discharge area.

When the second electromagnet 80 and the first electromagnet 79 are closed, the repulsive magnetic field between the second electromagnet 80 and the first electromagnet 79 disappears. At this time, the return spring 82 pushes the first electromagnet 79 and the first clutch column 81 to return to their original position, so that one end of the first clutch column 81 moves out of the first clutch groove 83, thereby disconnecting the connection between the second clutch 43 and the second connecting rod 42, and between the third transmission column 36 and the first clutch 37.

[0025] Example 2 Please see Figure 1 and Figure 2 The present invention provides a technical solution: the crane body 2 integrates an intelligent scheduling module, which includes a task receiving module, a task execution module and a task feedback module. The task receiving module receives task commands, the task execution module automatically controls the unmanned grab crane to work according to the content of the received task commands, and the task feedback module feeds back the work completion status to the control center.

[0026] In summary, when using this unmanned grab crane scheduling device for the raw material warehouse, the crane body 2 moves along the overhead crane track 1. When the grab mechanism 6 moves to the grab position, the crane body 2 stops moving. At this time, the output end of the first servo motor 14 drives the first lead screw 15 to rotate, causing the first slider 16 to push the push column 17 and the moving plate 23 to move. This causes the second side plate 7 to move the fixed box 8 away from the grab mechanism 6. At the same time, the telescopic end of the electric telescopic rod 5 drives the baffle 88 to move away from the grab mechanism 6. Then, the crane body 2 drives the grab... The bucket mechanism 6 moves down and grabs the material by driving the grab bucket mechanism 6. Then, the grab bucket mechanism 6 moves up and the output end of the first servo motor 14 drives the first lead screw 15 to reset and rotate, so that the first slider 16 drives the push column 17 and the moving plate 23 to reset and move, so that the second side plate 7 drives the fixed box 8 to move towards the grab bucket mechanism 6. At the same time, the extension end of the electric telescopic rod 5 pushes the baffle 88 to move towards the grab bucket mechanism 6. The grab bucket mechanism 6 is limited and supported by the limit block 9. Then, the crane body 2 moves along the crane track 1 to the unloading position. According to the material feeding direction, the corresponding first clutch 37 is activated and the corresponding second clutch 43 is disengaged. In this case, as the grab mechanism 6 moves, the first rack 10 drives the first transmission gear 12 to rotate, causing the rotating rod 11 to drive the drive rod 19 to rotate via the first bevel gear 20, and drive the drive column 21 to rotate via the spline member 22 and spline groove 18, causing the moving plate 23 to drive the first transmission rod 24 to rotate, which in turn drives the second transmission rod 27 to rotate via the first pulley 26, and drives the first transmission column 28 to rotate via the third bevel gear 30, thereby driving a second transmission column 35 to rotate. The second transmission column 35 drives the second pulley 38 to rotate, which in turn drives the first clutch 37 to rotate, thereby driving the third transmission column 36 to rotate. The first connecting rod 39 is driven to rotate by the sixth bevel gear 40, which in turn drives the connecting column 77 to rotate by the first drive gear 41, causing the screw conveyor shaft 52 to rotate for material conveying. The first transmission column 28 drives the third transmission rod 89 to rotate via the sixth pulley 90, which in turn drives the second transmission column 35 to rotate. The second transmission column 35 drives the second pulley 38 to rotate the first clutch 37, which in turn drives the third transmission column 36 to rotate. This, in turn, drives the first connecting rod 39 to rotate via the sixth bevel gear 40, which in turn drives the connecting column 77 to rotate by the first drive gear 41, causing the fifth bevel gear 34 to drive the fixed shaft 65 to rotate. The fourth pulley 66 drives the rotating roller 61 to rotate, and the seventh pulley 93 drives the connecting shaft 94 to rotate. According to the material feeding direction, the corresponding second clutch 43 is activated and the corresponding first clutch 37 is closed. In this case, as the grab mechanism 6 moves, the first rack 10 drives the first transmission gear 12 to rotate, causing the rotating rod 11 to drive the driving rod 19 to rotate through the first bevel gear 20, and drive the driving column 21 to rotate through the spline 22 and spline groove 18, causing the moving plate 23 to drive the first transmission rod 24 to rotate, which in turn drives the second transmission rod 27 to rotate through the first pulley 26, and drives the first transmission column 28 to rotate through the third bevel gear 30, thereby driving a second transmission column 35 to rotate. The second transmission column 35 drives the third pulley 44 to rotate the second clutch 43, which in turn drives the second connecting rod 42 to rotate, which in turn drives the connecting rod 45 to rotate through the seventh bevel gear 46, causing the connecting rod 45 to drive the third driving gear 49 to rotate through the second driving gear 47, which in turn drives the fixed rod 48 to drive the fourth driving gear 50 to rotate through the third driving gear 49, thereby driving the connecting column 77 to rotate. The movement of the screw conveyor shaft 52 causes it to rotate, thus conveying material. The first transmission column 28 drives the third transmission rod 89 to rotate via the sixth pulley 90, which in turn drives the second transmission column 35 to rotate. The second transmission column 35 drives the third pulley 44 to rotate the second clutch 43, which in turn drives the second connecting rod 42 to rotate. The seventh bevel gear 46 then drives the connecting rod 45 to rotate, which in turn drives the third drive gear 49 via the second drive gear 47. The fixed rod 48 drives the fourth drive gear 50 via the third drive gear 49, which in turn drives the connecting column 77 to rotate. The fifth bevel gear 34 then drives the fixed shaft 65 to rotate, which in turn drives the rotating roller 61 via the fourth pulley 66. The seventh pulley 93 then drives the connecting shaft 94 to rotate. Regardless of the direction of material movement of the grab bucket mechanism 6, the screw conveyor shaft 52 is driven to convey material, which drives the rotating roller 61 to rotate and drives the other rotating roller to rotate via the conveyor belt 62. This causes the material leaking from the surface of the conveyor belt 62 to be conveyed into the lower material pipe 63. The rotation of the connecting shaft 94 drives the reciprocating screw 68 to rotate via the eighth bevel gear 91. This causes the reciprocating screw 68 to move the second slider 70, which in turn causes the second rack 69 to move back and forth. This movement of the second rack 69, via the second transmission gear 71 and the third clutch 73, drives the third connecting rod 72 to rotate. The third connecting rod 72, through the fifth pulley 75, drives the threaded rod 74 to rotate back and forth. This causes the scraper 76 to move back and forth along the inside of the fixed box 8, pushing the material leaking from the grab mechanism 6 at the bottom of the fixed box 8 towards the two discharge heads 59, where it falls onto the surface of the conveyor belt 62 and then into the conveyor through the discharge pipe 63. Inside the machine 51, the material is conveyed upward by the spiral conveyor shaft 52, so that the material leaking inside the conveyor 51 is input into the storage box 54 through the discharge pipe 53 for storage. When it moves to the unloading position, the output end of the second servo motor 92 drives the threaded rod 74 to rotate, which drives the scraper 76 to make a back-and-forth stroke, pushing the material leaking at the bottom of the fixed box 8 cavity into the two discharge heads 59, so that the material leaking falls on the surface of the conveyor belt 62. At this time, the fifth pulley 75 cannot drive the third connecting rod 72 to rotate through the third clutch 73. The third clutch 73 is resisted, causing the second clutch column 86 to move into the second moving groove 84, so that the third clutch 73 cannot be driven to rotate. At this time, the third connecting rod 72 rotates freely. Then, the crane body 2 moves along the top of the crane track 1. When the grab bucket mechanism 6 moves to the grab position, the crane body 2 stops moving. At this time, the output end of the first servo motor 14 drives the first lead screw 15 to rotate, causing the first slider 16 to push the push column 17 and the moving plate 23 to move, causing the second side plate 7 to drive the fixed box 8 to move away from the grab bucket mechanism 6. At the same time, the extension end of the electric telescopic rod 5 drives the baffle 88 to move away from the grab bucket mechanism 6. Then, the crane body 2 drives the grab bucket mechanism 6 to move down. At this time, the grab bucket mechanism 6 pulls the bottom end of the pipe 58 down. Before discharging, the switch valve 55 is opened, so that the leaking material inside the storage box 54 falls into the pipe 58 through the switch valve 55, and then falls to the discharge position through the bottom end of the pipe 58. Then the switch valve 55 can be closed, the pump 57 is started, and pressurized gas is input into the pipe 58, thereby pushing the leaking material inside the pipe 58 to be discharged. Then the material inside the grab bucket mechanism 6 is discharged. The grab and discharge work is carried out according to the above steps.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
