[0002] Sinter is an important raw material in blast furnace smelting, and the stability of sinter composition plays a necessary role in the stable operation of blast furnace. At present, manual sampling is often used for sampling sinter on the sintering machine. However, the process of manual sampling not only has potential safety hazards, but also causes uneven sampling due to the observation error of the human eye, resulting in poor sampling representativeness and difficulty in fully playing a guiding role in the subsequent production process. Correspondingly, although the automatic sampling robot set in the prior art can replace manual sampling to avoid the error of manual operation, the volume of the robot is too large, it is easily affected by the environment, and spare parts need to be frequently replaced, resulting in too high investment cost. Therefore, how to make the samples taken from sinter have representativeness, avoid the influence of human factors, and occupy less space and have lower investment cost than the automatic sampling robot is a problem that needs to be solved by those skilled in the art at present.

[0031] Sintered ore is an important raw material in blast furnace smelting. The stability of the sintered ore composition plays a necessary role in the stable operation of the blast furnace. At present, manual sampling is often used for the sampling work of sintered ore on the sintering machine. However, the manual sampling process not only has potential safety hazards, but also causes uneven sampling due to the observation error of the human eye, resulting in poor sampling representativeness and difficulty in fully playing a guiding role in the subsequent production process. Correspondingly, although the automatic sampling robot set in the prior art can replace manual sampling to avoid the error of manual operation, the robot body is too large, vulnerable to the environment, requires frequent replacement of spare parts, and the investment cost is too high. Therefore, how to make the samples taken from sintered ore have representativeness, avoid the influence of human factors, and occupy less space and have lower investment cost than the automatic sampling robot is a problem that needs to be solved by those skilled in the art at present.

[0032] The technical solution of this embodiment will be further described below in conjunction with the accompanying drawings and through specific implementation manners.

[0033] As Figures 1 - 6 shown, this embodiment provides an automatic sampling device for sintered ore, including an electro-hydraulic push rod 10, a connecting rod assembly 20, a connecting rod base 30 and a hopper 40. One end of the connecting rod assembly 20 is rotatably connected to the output end of the electro-hydraulic push rod 10, and the other end is limited in the connecting rod base 30. The hopper 40 is welded to the connecting rod assembly 20. When the electro-hydraulic push rod 10 extends, it can drive the connecting rod assembly 20 to rotate in the connecting rod base 30 and drive the hopper 40 to flip to the opening of the sealing cover 100 for sampling. A travel switch is provided on the electro-hydraulic push rod 10 to limit its extension range.

[0034] Specifically, in this embodiment, through the settings of the electro-hydraulic push rod 10, the connecting rod assembly 20 and the hopper 40, when the electro-hydraulic push rod 10 operates, it can drive the connecting rod assembly 20 to rotate, and then realize the rotation of the hopper 40 until the hopper 40 flips to the opening of the sealing cover 100 for sampling, so as to achieve the effect of automatic sampling. Further, the connecting rod base 30 can support the connecting rod assembly 20 and limit it at the same time, so that the connecting rod assembly 20 can only rotate and will not move linearly, so as to achieve the rotation effect of the hopper 40. Optionally, a travel switch is also provided on the electro-hydraulic push rod 10, which can limit its extension range to avoid damage after exceeding its action range.

[0035] The specific structure of the automatic sampling device for sintered ore in this embodiment will be described below.

[0036] As Figure 1As shown, in this embodiment, the automatic sampling device for sintered ore includes an electro-hydraulic push rod 10, a connecting rod assembly 20, a connecting rod base 30, and a hopper 40. Specifically, in this embodiment, the electro-hydraulic push rod 10 is arranged on one side of the sealing cover 100 of the sintered ore. One end of the connecting rod assembly 20 is rotatably connected to the output end of the electro-hydraulic push rod 10. Thus, when the electro-hydraulic push rod 10 extends or retracts, it can drive the connecting rod assembly 20 to synchronously change its position. Further, the other end of the connecting rod assembly 20 is limited in the connecting rod base 30. Furthermore, when the electro-hydraulic push rod 10 extends, it can drive the connecting rod assembly 20 to rotate in the connecting rod base 30. Specifically, the hopper 40 is welded to the connecting rod assembly 20. Furthermore, when the connecting rod assembly 20 rotates in the connecting rod base 30, it can drive the hopper 40 to flip until the hopper 40 can abut against and connect to the opening of the sealing cover 100, thereby sampling the sintered ore in the sealing cover 100 to achieve the effect of automatic sampling.

[0037] Combined with Figures 2 - 4 As shown, in this embodiment, a first pin shaft 11 is arranged on the electro-hydraulic push rod 10, and a head 12 is arranged at the output end of the electro-hydraulic push rod 10. An activity groove 121 is arranged on the head 12 and a second pin shaft 13 is installed. A push rod base 14 is also arranged below the electro-hydraulic push rod 10. Optionally, in this embodiment, there are two first pin shafts 11, and the two first pin shafts 11 are respectively located on both sides of the electro-hydraulic push rod 10 and are slidably arranged in the push rod base 14. Thus, the height of the electro-hydraulic push rod 10 is increased through the push rod base 14, facilitating the subsequent driving of the connecting rod assembly 20 on the same horizontal plane and improving the transmission stability. Exemplarily, the push rod base 14 is set as a square plate and is vertically welded to the steel plate supporting the bottom of the device. A long hole is horizontally opened on the push rod base 14, and the first pin shaft 11 can be inserted and slidably arranged in the long hole, so that the position of the electro-hydraulic push rod 10 on the push rod base 14 is adjustable. Specifically, the push rod base 14 and the first pin shaft 11 are arranged in one-to-one correspondence, that is, in this embodiment, there are also two push rod bases 14, and both are made of steel plates. In other embodiments, other materials can also be selected, which will not be elaborated here. Exemplarily, the height of the push rod base 14 is set to 300 mm.

[0038] Combined with Figure 2 and Figure 5As shown, specifically, in this embodiment, the second pin shaft 13 is arranged to penetrate through the end head 12 and is rotatably connected to the connecting rod assembly 20 in the movable groove 121, thereby realizing the rotational connection between the electro-hydraulic push rod 10 and the connecting rod assembly 20. Exemplarily, the movable groove 121 is arranged to penetrate in the vertical direction and is opened on the side facing the connecting rod assembly 20, so as to facilitate the insertion of the connecting rod assembly 20 into the movable groove 121. Specifically, a first movable hole is arranged on the connecting rod assembly 20, and second movable holes are penetrated through the two side walls of the movable groove 121. Thus, the second pin shaft 13 sequentially penetrates through the second movable hole and the first movable hole, and the rotational connection with the connecting rod assembly 20 can be realized. Further, limiting discs are arranged at both ends of the second pin shaft 13, and the outer diameter of the limiting disc is larger than the inner diameter of the second movable hole. Thus, the second pin shaft 13 will not fall off in the end head 12, so as to ensure the stable connection between the connecting rod assembly 20 and the electro-hydraulic push rod 10.

[0039] Further, in this embodiment, a travel switch is arranged on the electro-hydraulic push rod 10 to limit the extension range of the end head 12. The corresponding installation and control methods will not be elaborated here. Correspondingly, a time relay is also arranged on the electro-hydraulic push rod 10 to control the extension or retraction frequency and holding duration of the electro-hydraulic push rod 10, and further limit the rotation frequency of the hopper 40 on the connecting rod assembly 20 and the connection duration with the opening of the sealing cover 100, so as to control the sampling period and sampling duration, improve the effect of automatic sampling, and avoid manual statistics of relevant durations and the quantity of sinter ore samples. Exemplarily, in this embodiment, the model of the electro-hydraulic push rod 10 is selected as DYTP700-240 / 110-P, and its maximum stroke can be 2500 mm.

[0040] Combined with Figure 5 and Figure 6 As shown, in this embodiment, the connecting rod assembly 20 includes a connecting plate 21 and a connecting rod 22, and the connecting plate 21 is rotatably connected to the output end of the electro-hydraulic push rod 10, that is, the first movable hole is arranged on the connecting plate 21, and the second pin shaft 13 penetrates through the connecting plate 21. Further, one end of the connecting rod 22 is fixedly connected to the connecting plate 21, and the other end is limited in the connecting rod base 30. The hopper 40 is arranged on the connecting rod 22, so as to ensure the stable limit of the connecting rod assembly 20 in the connecting rod base 30. When the electro-hydraulic push rod 10 extends, the connecting plate 21 can rotate relative to the second pin shaft 13 under its limit, and then drive the connecting rod 22 to rotate in the connecting rod base 30, realizing the flipping effect of the hopper 40. Exemplarily, the connecting plate 21 is arranged as an elliptical plate, and when it rotates, the end head 12 will not interfere with it. Exemplarily, the length of the connecting rod 22 is set to 1500 mm.

[0041] As Figure 6As shown in the figure, in this embodiment, the connecting rod base 30 includes two parallel and spaced-apart limiting plates, and limiting holes are provided on the limiting plates. The connecting rod 22 can sequentially pass through the limiting holes on the two limiting plates, so as to realize the limiting placement of the connecting rod assembly 20 on the connecting rod base 30 without affecting the rotation effect of the connecting rod assembly 20. Specifically, in this embodiment, the limiting plates are made of steel plates, or can be made by welding multiple sections of steel plates as required. Exemplarily, the top of the limiting plate is set to an elliptical structure to avoid potential safety hazards caused by right-angle settings. Exemplarily, the height of the limiting plate is set to 300 mm to ensure that the electro-hydraulic push rod 10 and the connecting rod assembly 20 can operate on the same horizontal plane.

[0042] Specifically, in this embodiment, the hopper 40 is set to a U-shaped structure and is located between the two limiting plates, and is connected to the outside of the connecting rod 22 by welding. Further, an opening is provided on the sealing cover 100, and the size of the hopper 40 is adapted to the size of the opening, so as to be able to convey the sintered ore in the sealing cover 100 to complete sampling. Specifically, when the hopper 40 abuts against the opening of the sealing cover 100 for sampling, an angle is formed between the bottom of the hopper 40 and the sealing cover 100, so as to facilitate the sliding of the sintered ore and improve the sampling efficiency. Exemplarily, when the electro-hydraulic push rod 10 is not working and the hopper 40 is not rotating, the hopper 40 is located above the opening of the sealing cover 100, and when the electro-hydraulic push rod 10 drives the connecting rod assembly 20 to rotate, the hopper 40 flips 75° from top to bottom to abut against the opening for sampling. This can not only reduce the driving stroke of the electro-hydraulic push rod 10, but also enable the hopper 40 to abut against the opening as soon as possible to improve the sampling efficiency. In other embodiments, the flipping angle and position of the hopper 40 can be set as required, which will not be elaborated here.

[0043] Working principle: An opening is made on the sealing cover 100 above the head pulley position of the finished ore after screening to facilitate sampling; the push rod base 14 is welded and the electro-hydraulic push rod 10 is installed; the connection with the electro-hydraulic push rod 10 is completed by using the connecting plate 21 and the connecting rod 22, and it is limited in the connecting rod base 30; the electro-hydraulic push rod 10 operates to drive the connecting rod assembly 20 to rotate, and the hopper 40 welded on the connecting rod 22 flips 75° from top to bottom until it abuts against the opening of the sealing cover 100 for sampling.

[0044] Specifically, the push rod base 14 and the connecting rod base 30 provide stable support for the electro-hydraulic push rod 10, the connecting rod assembly 20 and the hopper 40. In this embodiment, a distribution box, a travel switch and a time relay are also equipped to ensure circuit connection and communication, and can limit the action and travel range of the electro-hydraulic push rod 10, and can control the sampling period and sampling duration, achieving the effect of automatic sampling.

[0045] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
