When the upper base 1003 extends into the smelting furnace 1, the recovery basket 1012 is used for receiving residues scraped out of the smelting furnace 1 by the scraper 1010; when the upper base 1003 is away from the smelting furnace 1, a blanking well 1019 is formed between the recovery basket 1012 and the two linear guides 1001 for pouring the molten liquid, and the protective cover is not limited to be arranged above the linear guides 1001 to protect the linear guides 1001 from the damage of the high-temperature alloy solution.

The cutting edge of the scraper 1010 is arc-shaped, and the curvature of the cutting edge is consistent with the internal curvature of the smelting furnace 1. The scrapers 1010 conform to the inner curvature of the melting furnace 1 to remove the slag remaining in the melting furnace 1.

When the furnace is used, the furnace cover 101 is opened, the ingot casting blank is added into the smelting furnace 1, and the cutting scraps are added into the cleaning basket 3 of the cleaning pool; starting the special-shaped roller 6 to heat the cleaning agent and continuously clean the cuttings under a warm-hot stirring state, after cleaning is finished, rotating the cleaning basket 3 in the cleaning tank 201 to pour the cuttings into the cleaning basket 3 in the washing tank 202, spraying clean water to wash and remove residual cleaning agent on the cuttings by the rotary spray head 7, then rotating the cleaning basket 3 in the washing tank 202 to pour the cleaned cuttings into the cleaning basket 3 of the drying tank 203, starting the fan 8 to blow off moisture on the cuttings, and then rotating the cleaning basket 3 of the drying tank 203 to pour the cuttings into the smelting furnace 1; the furnace cover 101 is well covered, after high-temperature smelting, the smelting furnace 1 is driven to dump by rotating the fifth rotating shaft 2042, dregs are remained in the smelting furnace 1 after molten liquid is dumped out, the lower base 1002 of the linear guide rail 1001 is started to move towards the smelting furnace 1 until the recovery basket 1012 is positioned at the position below the inlet of the smelting furnace 1, the driving wheel 1016 rotates the first half gear 1014 to engage the rack 1004 to enable the upper base 1003 to move towards the inside of the smelting furnace 1, meanwhile, the outer cylinder 1005 also moves towards the inside of the smelting furnace 1 to eject the scraper 1010 downwards to contact the smelting furnace 1 through the third connecting rod 1011, then, the upper base 1003 reversely moves when the second half gear 1015 engages the rack 1004, and the scraper 1010 is retracted by reversely moving the outer cylinder 1005 after the scraper 1010. The above-mentioned drives are all different drives and are not limited to the use of motors, belts or reducers.

The invention has the beneficial effects that:

1. compared with the prior art, the novel point of a cleaning line is added, the cutting fluid is dissolved and washed by using the cleaning agent, and the cutting fluid attached to the surface of the cutting chip is removed in a clean water washing and blow-drying mode, so that the situation that the cutting fluid is brought into a smelting furnace to cause difficult melting is avoided, and the smelting quality of the environment-friendly silicon brass alloy is improved;

2. the scraping mechanism realizes the reciprocating motion of the upper base by matching the two half gears and the rack, simultaneously forces the scraper to realize the function of up-and-down stretching by utilizing the movement of the outer cylinder and the pushing of the third connecting rod, and the scraper is locked when the screw does not rotate, thereby being safe and reliable;

3. the process of dumping, opening and closing the cover of the melting furnace does not need manual operation, so that the labor cost is saved, and accidents are reduced.

The above-mentioned embodiments do not limit the scope of the present invention, and various modifications and improvements of the technical solutions of the present invention by those skilled in the art should be included in the protection scope defined by the claims of the present invention without departing from the design concept of the present invention.
