Description

Technical Field

[0001] The utility model relates to the technical field of slag cleaning and skimming in smelting furnaces, and particularly relates to a slag skimming shovel. Background Art

[0002] A slag skimming shovel is a tool used in the smelting process to remove a large amount of slag on the surface of the melt to improve the quality of the final product. It is generally fixedly connected to a forklift. The slag skimming shovel includes a slag skimming shovel head and a shovel arm connected between the shovel head and the forklift. Existing shovel arms usually use heat-resistant square tubes, and one end of the heat-resistant square tube is directly welded to the surface of the slag skimming shovel head.

[0003] The existing shovel head with the above structural form has the following problems: Since the temperature in the smelting furnace is relatively high, the shovel head is prone to deformation after long-term use, resulting in cracks in the weld between the shovel head and the shovel arm. The molten aluminum in the smelting furnace enters the square tube from the weld, damaging the connection between the shovel head and the square tube, and causing the shovel head to fall off from the end of the shovel arm. Summary of the Invention

[0004] In order to solve the problem that the shovel head of the existing slag skimming shovel is prone to falling off, the utility model provides a slag skimming shovel. The connection between the shovel head and the shovel arm is firm, which can effectively prevent the backflow of molten aluminum, thereby increasing the service life of the slag skimming shovel.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A slag skimming shovel includes a shovel head body and a shovel arm connected to the shovel head body. The shovel head body includes a connection part and a shovel tooth part arranged from top to bottom. One side of the connection part is provided with a sleeve structure. The sleeve forms an angle with the connection part. A strengthening part is arranged between the sleeve and the connection part. One end of the strengthening part is fixedly connected to the sleeve, and the other end is fixedly connected to the connection part. Multiple gaps are arranged at intervals at the bottom of the shovel tooth part. Both ends of the shovel tooth part are bent inwards to form bending parts. The shovel arm is inserted into the sleeve.

[0007] Furthermore, the connection part is trapezoidal, the shovel tooth part is rectangular, and the bottom of the connection part is fixedly connected to the top of the shovel tooth part. The connection part and the shovel tooth part are integrally cast, and the connection is firm.

[0008] Furthermore, the thickness of the shovel tooth part is greater than the thickness of the connection part, and the connection between the connection part and the shovel tooth part is in an oblique angle transition. Increasing the thickness of the shovel teeth effectively improves the durability of the shovel teeth.

[0009] Furthermore, the cross-section of the sleeve is in the shape of a "hui" character, and a rectangular slot is arranged at the center of the sleeve. The slot matches the shovel arm. The shovel arm is inserted into the sleeve, and the contact area between the two is large, and the connection is more firm.

[0010] Furthermore, the sleeve is stepped, and the cross-sectional area of ​​the sleeve increases step by step from the sleeve opening toward the inside, so that the structure between the sleeve and the connecting portion is stable.

[0011] Furthermore, the angle between the sleeve and the connecting portion is a right angle, which improves the slag removal efficiency and saves operation time.

[0012] Furthermore, the notch and the bent portion are both triangular, and the top angle of the notch is an obtuse angle, so as to avoid missing slag in the aluminum liquid.

[0013] Furthermore, the reinforcement part is plate-shaped and is located on both sides and the bottom of the sleeve respectively. The reinforcement part is used to strengthen the structural strength of the shovel head body and prevent the shovel head body from deformation and distortion.

[0014] Through the above technical solution, the beneficial effects of the utility model are:

[0015] The utility model is provided with an integrated connection part, a shovel tooth part and a sleeve, a reinforcement part is provided between the connection part and the sleeve, and the shovel arm is inserted into the sleeve. Compared with the shovel arm being directly welded on the surface of the shovel head body, the contact area between the shovel arm and the shovel head body is increased; and the thickness of the shovel tooth part is greater than the thickness of the connection part, and the sleeve and the shovel arm form a mortise and tenon structure, which can effectively prevent the problem of aluminum liquid backflow after welding, so that the shovel arm can work in the furnace for a longer time.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 4 As shown, this embodiment provides a slag scraper, including a shovel head body and a shovel arm connected to the shovel head body, the shovel head body is used to scrape off slag floating in the aluminum liquid, and the shovel arm is used to connect the shovel head and the conveyor. In this embodiment, the shovel arm is made of heat-resistant steel.

[0023] like Figure 1As shown, the shovel head body includes a connecting portion 1 and a shovel tooth portion 2 arranged from top to bottom, the connecting portion 1 is trapezoidal, the shovel tooth portion 2 is rectangular, the bottom of the connecting portion 1 is fixedly connected to the top of the shovel tooth portion 2, and a plurality of notches 21 are arranged at intervals at the bottom of the shovel tooth portion 2. Specifically, the notches 21 are triangular, and the top angle of the notches 21 is an obtuse angle.

[0024] like Figure 2 As shown, a sleeve 3 structure is provided on one side of the connecting portion 1, and the sleeve 3 is angled with the connecting portion 1, and the angle between the sleeve 3 and the connecting portion 1 is a right angle, and the shovel arm is inserted into the sleeve 3; in order to increase the structural strength of the shovel head body, a reinforcement portion 4 is provided between the sleeve 3 and the connecting portion 1, and one end of the reinforcement portion 4 is fixedly connected to the sleeve 3 and the other end is fixedly connected to the connecting portion 1; in order to prevent the slag from slipping off from the two ends of the shovel head body during the slag scraping process, the two ends of the shovel tooth portion 2 are bent inward to form a bending portion 22, and the bending portion 22 is triangular.

[0025] As an implementable embodiment, the cross section of the sleeve 3 is in the shape of a "U". A rectangular slot is provided at the center of the sleeve 3, and the slot matches the shovel arm. The sleeve 3 is located on the central axis of the shovel head body.

[0026] like Figure 3 As shown, in order to increase the structural strength of the shovel tooth portion 2 and enhance the service life of the shovel teeth, the thickness of the shovel tooth portion 2 is greater than the thickness of the connecting portion 1, and the connection between the connecting portion 1 and the shovel tooth portion 2 is an oblique transition; the upper surface of the sleeve 3 is flush with the upper surface of the connecting portion 1, and the reinforcing portion 4 is respectively located on both sides of the sleeve 3 and the bottom of the sleeve 3, and the reinforcing portion 4 is plate-shaped, and the direction of the reinforcing portion 4 is perpendicular to the surface of the sleeve 3.

[0027] Specifically, the sleeve 3 is stepped, and the cross-sectional area of ​​the sleeve 3 increases step by step from the opening of the sleeve 3 inward.
