Description

Technical Field

[0001] This utility model relates to the field of aluminum product manufacturing technology, specifically to a slag removal head for a slag removal vehicle. Background Technology

[0002] During the melting of aluminum ingots, a layer of slag, composed of oxides, flux residues, and unmelted impurities, forms on the surface of the molten aluminum. The process of removing this slag from the surface of the molten aluminum is called "slag removal." The main purpose of slag removal is to remove impurities and ensure the purity of the molten aluminum. Secondly, it is to prevent defects such as porosity and inclusions, thus avoiding affecting the quality of the castings. Currently, slag removal is generally performed using a slag removal machine with a slag removal head.

[0003] The temperature of molten aluminum keeps the slag removal head in a high-temperature environment for a long time, making the metal material prone to oxidation. At the same time, the flux and residual oxides in the molten aluminum will accelerate chemical corrosion. In addition, when removing slag, the slag removal head needs to repeatedly scrape the surface of the molten aluminum or stir the melt, which causes friction with hard floating slag, resulting in wear of the slag removal head. However, the slag removal head used for slag removal is generally welded to the connecting device of the slag removal car, and it is inconvenient to disassemble the damaged slag removal head from the slag removal car. Summary of the Invention

[0004] This utility model addresses the problems of easily damaged muck-loading heads and inconvenient disassembly and installation on muck-loading trucks; it provides a muck-loading head for muck-loading trucks that facilitates easy disassembly and installation.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A slag-scraping head for a slag-scraping truck includes a slag-scraping plate, a connecting rod, and a sleeve. The top surface of the slag-scraping plate has a recessed groove in the center. The connecting rod passes through the groove, and multiple bolts are mounted on the connecting rod within the groove. The free end of each bolt 1 movably passes through the connecting rod and is threadedly connected to a threaded blind hole 1 opened at the bottom of the groove. Sleeves are slidably fitted on the connecting rods on both sides of the groove. The front and rear side plates of the two sleeves are connected by connectors. The front connectors include bolts 2 and 3. The free end of bolt 2 movably passes through the front side plate of the left sleeve and the slag-scraping plate in sequence, and is threadedly connected to a threaded blind hole 2 on the front side plate of the right sleeve. The free end of bolt 3 movably passes through the front side plate of the right sleeve and the slag-scraping plate in sequence, and is threadedly connected to a threaded blind hole 3 on the front side plate of the left sleeve.

[0007] Furthermore, when the head of bolt one presses against the top surface of the connecting rod, there is a gap between the free end of bolt one and the inner bottom of the threaded blind hole one; when the head of bolt two presses against the left side of the left sleeve front side plate, there is a gap between the free end of bolt two and the inner bottom of the threaded blind hole two; when the head of bolt three presses against the right side of the right sleeve front side plate, there is a gap between the free end of bolt three and the inner bottom of the threaded blind hole three.

[0008] Furthermore, each sleeve has ribs connected to its front and rear outer sides and bottom surface, and the ribs on the same side of the two sleeves are symmetrical about the slag removal plate.

[0009] Furthermore, each of the ribs is a right-angled triangular plate, with a sleeve fixedly connected to one right-angled side of each rib, and the other right-angled side of the rib being flush with the side of the sleeve facing the slag removal plate.

[0010] Furthermore, a limiting hole is provided on the slag removal plate between the two symmetrical ribs, and a limiting post is provided on the opposite surface of the symmetrical ribs. The limiting posts on the two ribs extend into the limiting hole between the two ribs.

[0011] Furthermore, there are at least two connecting pieces between the front side plates of the two sleeves; and at least two connecting pieces between the rear side plates of the two sleeves.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] When the slag removal plate and the connecting rod of this utility model are connected, a bolt is used to connect the connecting rod and the slag removal plate. The two sleeves on the connecting rod are connected to the slag removal plate through a connecting piece. When this utility model is used, it can improve the connection strength between the slag removal plate and the connecting rod, and it is easy to disassemble and assemble, and it is convenient to replace the damaged slag removal plate.

[0014] The slag removal plate of this utility model is also connected to the sleeves on the left and right sides by ribs. The ribs on the left and right sides of the slag removal plate are symmetrical, which improves the strength of the slag removal plate during use.

[0015] When in use, the threaded portions of bolts one, two, and three will not come into contact with molten aluminum, thus preventing the molten aluminum from solidifying and making bolts one, two, and three difficult to rotate. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] like Figures 1 to 7 As shown, a slag-removing head for a slag-removing vehicle includes a slag-removing plate 1 with slag-removing teeth 11 at its lower end and multiple filtrate holes 12. It also includes a connecting rod 2 and a sleeve 3. A groove 4 is recessed in the center of the top surface of the slag-removing plate 1. The groove 4 is a U-shaped groove with openings at the top and left and right ends. The connecting rod 2 is a rectangular rod whose front and rear side distances correspond to the front and rear side distances of the groove 4. The connecting rod 2 passes through the groove 4. Multiple bolts 19 are provided on the connecting rod 2 within the groove 4. The free ends of the bolts 19 movably pass through the connecting rod 2 and are threadedly connected to a threaded blind hole 5 opened at the bottom of the groove 4. The connecting rod 2 has a through hole 20 for the free ends of the bolts 19 to pass through. Sleeves 3 are slidably fitted onto the connecting rod 2 on both the left and right sides of the groove 4. The sleeves 3 are rectangular cylinders whose inner surfaces slide in contact with the connecting rod 2. The front and rear side plates of the two sleeves 3 are connected by connectors. The front connectors include bolt 2 6 and bolt 3 7. The free end of bolt 2 6 passes through the front side plate of the left sleeve 3 and the slag removal plate 1 in sequence. The free end of bolt 2 6 is threaded to the threaded blind hole 2 8 on the front side plate of the right sleeve 3. The front side plate of the left sleeve 3 is provided with a through hole 2 10 for the free end of bolt 2 6 to pass through. The slag removal plate 1 is provided with a through hole 1 13 for the free end of bolt 2 6 to pass through. The free end of bolt 3 7 passes through the front side plate of the right sleeve 3 and the slag removal plate 1 in sequence. The free end of bolt 3 7 is threaded to the threaded blind hole 3 9 on the front side plate of the left sleeve 3. The front side plate of the right sleeve 3 is provided with a through hole 3 14 for the free end of bolt 3 7 to pass through. The slag removal plate 1 is provided with a through hole 2 15 for the free end of bolt 3 7 to pass through.

[0026] When the head of bolt 19 presses against the top surface of connecting rod 2, there is a gap between the free end of bolt 19 and the inner bottom of threaded blind hole 5. When the head of bolt 26 presses against the left side of the front side plate of left sleeve 3, there is a gap between the free end of bolt 26 and the inner bottom of threaded blind hole 28. The inner bottom of threaded blind hole 28 is the side opposite to the opening of threaded blind hole 2. When the head of bolt 37 presses against the right side of the front side plate of right sleeve 3, there is a gap between the free end of bolt 37 and the inner bottom of threaded blind hole 39. The inner bottom of threaded blind hole 39 is the side opposite to the opening of threaded blind hole 39.

[0027] Each sleeve 3 is connected to a rib plate 16 on its front and rear outer sides and bottom surface. The rib plates 16 on the same side of the two sleeves 3 are symmetrical about the slag removal plate 1.

[0028] Each of the ribs 16 is a right-angled triangular plate. The sleeve 3 is fixedly connected to the straight surface of one right-angled side of each rib 16, and the straight surface of the other right-angled side is flush with the side of the sleeve 3 facing the slag removal plate 1.

[0029] A limiting hole 18 is provided on the slag removal plate 1 between the two left and right symmetrical ribs 16, and a limiting post 17 is provided on the opposite surface of the left and right symmetrical ribs 16. The limiting post 17 on the two ribs 16 extends into the limiting hole 18 between the two ribs 16.

[0030] There are at least two connecting members between the front side plates of the two sleeves 3, and the two connecting members are arranged from top to bottom; there are at least two connecting members between the rear side plates of the two sleeves 3, and the two connecting members are arranged from top to bottom.

[0031] The connecting rod 2 of this utility model is connected to the muck loader;

[0032] During installation, the sleeves 3 on the left and right sides of the connecting rod 2 are not initially connected by bolts 2 6 and 3 7. The distance between the limiting posts 17 on each pair of symmetrical ribs 16 is greater than the thickness of the slag-removing plate 1. The connecting rod 2 is inserted into the groove 4 on the slag-removing plate 1. The two sleeves 3 are located on the left and right sides of the slag-removing plate 1, respectively. The free end of each bolt 19 passes through the through hole 1 on the connecting rod 2 from top to bottom. The free end of each bolt 1 is threaded into the threaded blind hole 5 opened at the bottom of the groove 4. The head of the bolt 1 presses against the top surface of the connecting rod 2, causing both sleeves 3 to move towards the slag-removing plate 1. Both sleeves contact the slag-removing plate. The limiting posts 17 on each rib 16 extend into the corresponding limiting holes 18. Subsequently, the free end of bolt 2 6 of the front connecting piece of the two sleeves 3 passes through the through hole 2 10 on the front side plate of the left sleeve 3. The threaded blind hole 8 of the front side plate of the right sleeve 3 is connected to the threaded end. The head of bolt 26 presses against the left side of the front side plate of the left sleeve 3. The free end of bolt 37 passes through the through hole 314 of the front side plate of the right sleeve 3. The free end of bolt 37 is threaded to the threaded blind hole 39 of the front side plate of the left sleeve 3. Similarly, the rear side plates of the two sleeves 3 are connected by a connector. At this time, the slag removal plate 1 and the connecting rod 2 are connected. The connection between the two sleeves 3 and the slag removal plate 1 by the connector can improve the connection strength between the slag removal plate 1 and the connecting rod 2. Moreover, the bolts 26 and 37 on the connector can ensure that the two sleeves 3 are subjected to balanced force, improve the connection strength between the two sleeves 3, and further improve the connection strength between the slag removal plate 1 and the connecting rod 2. At the same time, the slag removal plate 1 is connected to the left and right sleeves 3 by the rib plate 16. The rib plates 16 on the left and right sides of the slag removal plate 1 are symmetrical, which improves the strength of the slag removal plate 1 when in use.

[0033] When the slag scraper plate 1 needs to be replaced, remove bolts 19, 6, and 7 to detach the slag scraper plate 1 from the connecting rod 2. Repeat the above process to replace the slag scraper plate 1.
