The device 107 has an inclined surface 107a to facilitate the conveying of the material 108 produced by the slag removal device 106 to the lifting platform 3; the slag removal device 106 is mainly used in the post-processing system of the elevated floor to remove the excess overflow and riser of the newly cast elevated floor; a pusher mechanism 5 has a retractable push rod 51, and a pusher plate 52 is provided at the end of the push rod 51. The pusher mechanism 5 is arranged on one side of the feeding position 32 of the lifting platform 3; when the push rod 51 is extended, the material 108 on the lifting platform 3 can be pushed into the input port 102 of the melting furnace 101; with this structure, automatic feeding operation can be carried out to improve safety and save costs. It will be explained in detail below.

The platform 1 is arranged around the furnace 101. There is a bottom space 104 between the platform 1 and the ground 103, which can be used to set up structures such as the conveyor belt 4. In this way, the aluminum soup splashing out of the furnace 101 can be blocked by the platform 1 to protect the conveyor belt 4. There is a top space 105 above the platform 1, which is convenient for personnel to walk, and thus can facilitate other operations such as manual feeding or furnace maintenance.

The channel 2 connects the bottom space 104 and the top space 105 of the platform 1, which can facilitate the lifting of the workbench 3 and the material 108 through the platform 1.

The lifting platform 3 is disposed in the channel 2 and can move up and down between a collecting position 31 and a feeding position 32 along the channel 2. As shown in FIG2 , when the lifting platform 3 is at the collecting position 31, it can collect the material 108 transported by the conveyor belt. As shown in FIG3-4 , when the lifting platform 3 is at the feeding position 32, the pushing mechanism 5 can facilitate pushing the material 108 into the input port 102 of the melting furnace 101 .

The conveyor belt 4 connects the collection position 31 of the lifting platform 3 and the slag outlet device 107 of a slag removal device 106 to transport the material 108 generated by the slag removal device 106 to the lifting platform 3. The material 108 can be the excess overflow channel and pouring riser of the completed elevated floor.

The pusher mechanism 5 has a retractable push rod 51, and a pusher plate 52 is provided at the end of the push rod 51. The pusher mechanism 5 is provided on one side of the feeding position 32 of the lifting worktable 3; when the push rod 51 is extended, the material 108 on the lifting worktable 3 can be pushed into the input port 102 of the melting furnace 101. The push rod 51 of the pusher mechanism 5 can be a hydraulic push rod or a pneumatic push rod, which can be conveniently controlled automatically.

An electric gate 6 may be provided at the input port 102 of the melting furnace 101. The electric gate 6 includes two rails 61, a door panel 62 and a hoist 63. The two rails 61 are provided on two sides of the input port 102 of the melting furnace 101. The door panel 62 may move up and down along the two rails 61. The hoist 63 may control the door panel 62 to move up and down to open or close the input port 102 of the melting furnace 101, so as to facilitate material feeding.

As shown in FIG6 , the automatic feeding mechanism 100 may further include a controller 7, which is electrically connected to the electric gate 6, the conveyor belt 4 and the pushing mechanism 5. The controller 7 may be a programmable logic controller (PLC), which can facilitate the automatic feeding operation, thereby improving safety and saving costs.

There are many ways to start the controller 7 to perform automatic feeding operations, such as setting a start switch (not shown in the figure) to facilitate the operator to start the controller, or setting a weight sensing unit 71. The weight sensing unit 71 is electrically connected to the controller 7 and can sense the weight of the lifting workbench 3 and the material 108. When the weight of the lifting workbench 3 and the material 108 exceeds a predetermined value, the signal is sent to the controller 7, and the controller 7 determines whether to perform the feeding operation, which can save manpower.

As shown in Figures 3 and 4, the automatic feeding mechanism 100 may further include a feeding platform 8, which is disposed between the feeding position 32 of the lifting worktable 3 and the input port 102 of the melting furnace 101, and the top of the feeding platform 8 is an inclined surface 81; when the material 108 on the lifting worktable 3 is pushed onto the feeding platform 8, the material 108 slides along the inclined surface 81 of the feeding platform 8 into the input port 102 of the melting furnace 101, which facilitates feeding.

As shown in Figures 1 and 2, the channel 2 has an opening 21 at a position relative to the conveyor belt, which can facilitate the collection of materials 108 when the lifting workbench 3 is located at the collection position 31, and prevent the materials 108 from falling from other directions through the channel 2.

The automatic feeding mechanism 100 may further include a burner compartment 11, which is disposed on the platform 1 and covers the burner of the melting furnace (not shown) to reduce noise and increase heat insulation effect.

There may be at least one ladder 12 on the platform 1, which connects the top of the platform 1 with the ground 103, making it convenient for workers to move to the platform 1.
