[0002] Metal smelting is the process of changing metal from a combined state to a free state. During the metal smelting process, sampling and testing of the molten metal is essential. By analyzing the composition of the molten metal, it is convenient to adjust the added elements in time and control the quality of the alloy.

[0003] For example, a molten metal sampling device with the publication number CN212134181U in China belongs to the field of metallurgy technology. It includes a sampling cup and a handheld rod; the sampling cup and the handheld rod are connected to form an integrated structure via a connecting plate; the sampling cup is provided with an end cap, which is sleeved on the handheld rod through an axial hole, and the upper end of the end cap is also connected to a push-pull rod. The molten metal sampling device of the utility model has a reasonable structure, low manufacturing cost, and is easy to operate. It can sample at any depth of the metal solution.

[0004] Some problems were found during use of the above-mentioned existing molten metal sampling device. First, it is necessary to keep pressing the push-pull rod downward during sampling to prevent the end cover from moving, while the other hand needs to hold the hand-held rod. Two-handed operation requires the operator to be too close to the furnace. During metal smelting, the melt releases a large amount of heat, the furnace temperature is high, and there is splashing of the molten metal. It is dangerous for the sampler to be too close to the furnace, and there is a safety hazard. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-3The utility model provides a technical solution: a sampling device, including an L-shaped hand-held rod 1, one end of the L-shaped hand-held rod 1 is fixedly connected to a sampling cup 101, an end cover 201 is provided above the sampling cup 101, a connecting rod 2 is fixedly connected to the end cover 201, a connecting groove 204 is provided in the connecting rod 2, the L-shaped hand-held rod 1 passes through the connecting groove 204, a dovetail slide 104 is provided on the L-shaped hand-held rod 1, a dovetail slider 302 is slidably installed in the dovetail slide 104, a triangular push block 301 is fixedly connected to the upper end of the dovetail slider 302, and the triangular push block 301 cooperates with the connecting groove 204.

[0020] In this embodiment, the sampling cup 101 is connected to the L-shaped hand-held rod 1, which can be used as a hanging rod to allow the sampling cup 101 to be inserted into the furnace from a distance. At the same time, the end cover 201 is placed on the sampling cup 101 to prevent the upper slag, covering agent, etc. from entering the sampling cup 101 during the process of the sampling cup 101 sinking into the molten metal. After the sampling cup 101 is completely immersed in the molten metal, the triangular push block 301 is moved and inserted into the connecting groove 204. Figure 1 As shown, at this time, the triangular push block 301 will lift the connecting rod 2, causing the connecting rod 2 to move upward. The movement of the connecting rod 2 will drive the end cover 201 to move, thereby opening the upper end of the sampling cup 101, so that the molten metal can enter the sampling cup 101 and be collected. After that, after the triangular push block 301 is reset, the end cover 201 will move down again to cover the inside of the sampling cup 101, and the sampling cup 101 can be taken out using the L-shaped handheld rod 1. The end cover 201 covers the sampling cup 101 after sampling to prevent slag and covering agent from entering the sampling cup 101 during the process of taking the sampling cup 101 out of the furnace.

[0021] Among them, in order to achieve the purpose of limiting the connecting rod 2 to move only up and down, this device adopts the following technical solution: a number of limiting rings 102 are fixed on the L-shaped hand-held rod 1, a handle 103 is fixed at the end of the L-shaped hand-held rod 1, a connecting piece 202 is fixed on one side of the connecting rod 2, and a connecting ring 203 is fixed on the other end of the connecting piece 202, and the connecting ring 203 is slidably connected to the L-shaped hand-held rod 1.

[0022] The connecting ring 203 is sleeved on the L-shaped hand-held rod 1, limiting the connecting rod 2 to move only up and down, preventing the connecting rod 2 from rotating and deflecting in the direction, resulting in the end cover 201 being unable to cover the sampling cup 101. The handle 103 makes it easy for the operator to hold the L-shaped hand-held rod 1, and the surface of the connecting rod 2 is engraved with scales, which makes it easy for the operator to observe the sinking depth of the sampling cup 101.

[0023] Among them, in order to achieve the purpose of always covering the end cover 201 on the sampling cup 101, this device adopts the following technical solutions: a return spring 205 is fixed in the connecting groove 204, the upper end of the return spring 205 is fixed to the L-shaped hand-held rod 1, a push rod 3 is fixed to one side of the triangular push block 301, the push rod 3 is slidably matched with the limiting ring 102, and a displacement handle 303 is fixed to the push rod 3 near the edge of the other end.

[0024] The limiting ring 102 slides with the push rod 3 to restrict the push rod 3 to move forward and backward. Holding the displacement handle 303 can drive the push rod 3 to move. The movement of the push rod 3 will drive the triangular push block 301 to move, and then push the connecting rod 2 upward. The return spring 205 can provide a certain thrust for the connecting rod 2, so that the connecting rod 2 has a downward force, so that the end cover 201 can always cover the sampling cup 101.

[0025] The working principle and usage process of the present invention are as follows: when in use, you need to hold the handle 103 to drive the sampling cup 101 deep into the furnace, and use the scale on the connecting rod 2 to control the sinking depth of the sampling cup 101, and then use the displacement handle 303 to move the push rod 3 forward. The forward movement of the push rod 3 will drive the triangular push block 301 to move. After the triangular push block 301 is inserted into the connecting groove 204, it will push up the connecting rod 2, and the upward movement of the connecting rod 2 will drive the end cover 201 to move up, thereby opening the upper end of the sampling cup 101, so that the molten metal can enter the sampling cup 101 and be collected. After that, after resetting the triangular push block 301, the connecting rod 2 will be reset under the push of the return spring 205, and re-cover the sampling cup 101. Use the L-shaped handheld rod 1 to take out the sampling cup 101. After the metal solidifies, manually pull the connecting rod 2 upward to invert the sampling cup 101, and use the metal's own gravity to demold and take out the ingot.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
