An automatic batching component 13 is provided above the cover plate 12. Fixed blocks 111 are fixedly connected to both the left and right sides of the melting furnace 11. The automatic batching component 13 includes a flat rack 131. The bottom of the flat rack 131 is fixedly connected to the top of the cover plate 12;

[0029] Two feed hoppers 132 are fixedly connected inside the flat rack 131. A discharge cylinder 133 is provided on the top of the flat rack 131. The bottom of the discharge cylinder 133 is in contact with a weighing device 134. The bottom of the weighing device 134 is fixedly connected to the top of the cover plate 12. The top of the weighing device 134 is at the same horizontal plane as the top of the flat rack 131. A connecting plate 331 is fixedly connected to the front of the discharge cylinder 133. A motor 332 is fixedly connected to the top of the flat rack 131. By setting the automatic batching component 13, specifically, after the material weighing is completed, the motor 332 is started to drive the discharge cylinder 133 to rotate through the connecting plate 331, driving the internal material to move. When the discharge cylinder 133 rotates to the position of the feed hopper 132, the material enters the melting furnace 11 through the feed hopper 132, automatically adding the material for batching, with higher efficiency. At the same time, the discharge cylinder 133 drives the material into the melting furnace 11, which can reduce the contact between the staff's hands and the material during the batching process, thereby greatly reducing the occurrence of safety hazards.

[0030] The bottom of the feed hopper 132 is fixedly connected to the top of the cover plate 12. The feed hopper 132 and the cover plate 12 communicate with each other. The top output end of the motor 332 is fixedly connected to the bottom of the connecting plate 331.

[0031] Two fixing blocks 111 are fixedly connected with a pull rod 112 at the top. A plug board 113 is fixedly connected to the back of the melting furnace 11. Two first threaded blocks 114 are fixedly connected to the top of the melting furnace 11. The two first threaded blocks 114 are inserted into the cover plate 12. Nuts 115 are threadedly connected to the outer surfaces of the two first threaded blocks 114. A rotating shaft 116 is fixedly connected to one side of each of the two fixing blocks 111 away from the melting furnace 11. The staff then pulls the pull rod 112 to drive the melting furnace 11 to flip forward. The melting furnace 11 drives the rotating shaft 116 to rotate on the experimental seat 1 through the fixing block 111.

[0032] The rotating shaft 116 is rotatably connected to the inner wall of the experimental seat 1. Two positioning rods 117 are fixedly connected to the top of each of the two fixing blocks 111. The bottom of the plug board 113 contacts a limiting block 14. Two support frames 141 are fixedly connected to the bottom of the limiting block 14. The two support frames 141 are fixedly connected to the inner side of the experimental seat 1 on the sides away from each other. A blowtorch 15 is fixedly connected to the back of the melting furnace 11. The front of the blowtorch 15 penetrates the melting furnace 11 and extends into the interior. A gas pipeline 151 is fixedly connected to the back of the blowtorch 15. A second threaded block 142 is fixedly connected to the top of the limiting block 14. A threaded ring 143 is threadedly connected to the outer surface of the second threaded block 142. After the liquid is drained, the melting furnace 11 will be driven to flip backward by the pull rod 112, so that the plug board 113 is inserted into the second threaded block 142, and then the threaded ring 143 is threadedly connected to the second threaded block 142 to fix the plug board 113, and then the melting furnace 11 is fixed. At this time, the melting furnace 11 is in a vertical state.

[0033] A flip cover 121 contacts the top of the cover plate 12. Positioning blocks 122 are fixedly connected to both the left and right sides of the cover plate 12. A clamping plate 123 is arranged on the back of the flip cover 121. The bottom of the clamping plate 123 is fixedly connected to the top of the cover plate 12. An opening 124 is formed in the front of the cover plate 12. A plurality of partition plates 125 are fixedly connected to the inner wall of the opening 124. A collar 126 is fixedly connected to the bottom of the cover plate 12. The front of the collar 126 is provided with a notch. The collar 126 is sleeved on the experimental seat 1. The bottom of the flip cover 121 is adapted to the opening 124. A slot is formed in the clamping plate 123. By arranging the partition plates 125, specifically, after the melting furnace 11 flips, the liquid inside will drain from the opening 124. Since a plurality of partition plates 125 are fixed to the inner wall of the opening 124, the liquid can be divided to reduce the flow rate of the liquid, so that the liquid can drain slowly, avoiding the large flow rate and large impact force when the liquid drains, which may pose a safety hazard to the surrounding staff and equipment and improving safety.

[0034] A convex plate 211 is fixedly connected to the front of the flip cover 121. A connecting block 212 is fixedly connected to the top of the flip cover 121. An elastic piece 213 is fixedly connected to the top of the connecting block 212. A round rod 214 is rotatably connected inside the flip cover 121. Support blocks 215 are fixedly connected to both the left and right sides of the round rod 214. The bottoms of the two support blocks 215 are fixedly connected to the top of the cover plate 12. Workers wear heat-resistant gloves and drive the flip cover 121 to turn upwards through the convex plate 211. The flip cover 121 then rotates on the round rod 214. When the elastic piece 213 contacts the clamping plate 123, the elastic piece 213 will be squeezed and deformed, so that it can be smoothly inserted into the clamping plate 123. After the elastic piece 213 is inserted into the clamping plate 123, the shape of the elastic piece 213 will be restored under the action of elasticity, thereby fixing the flip cover 121.

[0035] A specific application of this embodiment is:

[0036] During use, the cover plate 12 is inserted into the top of the experimental base 1 through the collar 126 at the bottom to seal the experimental base 1. During the docking process, the positioning block 122 is inserted into the two positioning rods 117 to position the cover plate 12. At the same time, the cover plate 12 will be inserted into the first threaded block 114. After the cover plate 12 is placed, the nut 115 is threadedly connected to the first threaded block 114 to fix the cover plate 12. Cut copper, tin and other materials into small pieces and place them separately in the feeding cylinder 133. Then the weighing device 134 will weigh the materials. When the required weight is placed, the motor 332 is started to drive the feeding cylinder 133 to rotate through the connecting plate 331. Since the top of the weighing device 134 and the top of the flat rack 131 are on the same plane, the materials inside will be driven to move when the feeding cylinder 133 rotates. When the feeding cylinder 133 rotates to the feeding hopper 132, the materials enter the melting furnace 11 through the feeding hopper 132. After the materials are discharged, the motor 332 rotates in the reverse direction to reset the feeding cylinder 133, so that the feeding cylinder 133 moves to the weighing device 134 again to weigh and mix the next material. In this way, the materials can be automatically weighed and added, with higher efficiency. At the same time, the feeding cylinder 133 drives the materials into the melting furnace 11, which can reduce the contact between the staff's hands and the materials during the batching process, thus greatly reducing the occurrence of safety hazards;

[0037] After the batching is completed, start the blowtorch 15 to melt the materials. The gas pipeline 151 is used to convey gas to the blowtorch 15. After the melting is completed, the staff wears heat-resistant gloves and drives the flip cover 121 to turn upward through the convex plate 211. The flip cover 121 rotates on the round rod 214. When the elastic piece 213 contacts the clamping plate 123, the elastic piece 213 will be squeezed and deformed, so that it can be smoothly inserted into the clamping plate 123. When the elastic piece 213 is inserted into the clamping plate 123, it will reset its shape under the action of elasticity, thus fixing the flip cover 121. At this time, the opening 124 is opened. Then rotate the threaded ring 143 counterclockwise to disassemble it, release the fixation of the melting furnace 11. The staff then pulls the pull rod 112 to drive the melting furnace 11 to turn forward. The melting furnace 11 drives the rotating shaft 116 to rotate on the experimental base 1 through the fixing block 111. After the melting furnace 11 is turned over, the liquid inside is discharged from the opening 124. Since several partition plates 125 are fixed on the inner wall of the opening 124, the liquid can be divided to reduce the flow rate of the liquid, so that the liquid can be discharged slowly, avoiding the large flow rate and large impact force when the liquid is discharged, which may pose a safety hazard to the surrounding staff and equipment, and improving safety;

[0038] Finally, after the liquid is drained, drive the melting furnace 11 to turn backward through the pull rod 112, so that the plug board 113 is inserted into the second threaded block 142, and then thread the threaded ring 143 onto the second threaded block 142 to fix the plug board 113, then the melting furnace 11 is fixed. At this time, the melting furnace 11 is in a vertical state. Then pull the flip cover 121 forcefully to make the elastic piece 213 leave the clamping plate 123 and release the fixation of the flip cover 121. After the flip cover 121 is reset, it will seal the opening 124 to reduce the heat loss during the heating process, and then the batching and melting experiments can be carried out again.
