[0021] Please refer to Figures 1-3 As shown in the figure, a coal blending and feeding mechanism for metallurgical coke production includes a bottom plate 1, two vertical plates 2 are fixed on the upper surface of the bottom plate 1, a top plate 3 is fixed between the opposite sides of the two vertical plates 2, a feeding mechanism 4 is arranged above the bottom plate 1, a scraping mechanism 5 is arranged above the feeding mechanism 4, a first pushing mechanism 6 is arranged below the top plate 3, a second pushing mechanism 7 is arranged above the top plate 3, the second pushing mechanism 7 drives the scraping mechanism 5 to move along the surface of the feeding mechanism 4, the scraping mechanism 5 includes a fixed frame 51, a scraper plate 52, a guide rod 53 and a spring 54, the lower end of the scraper plate 52 penetrates through the bottom of the fixed frame 51, the guide rod 53 is connected with the top of the scraper plate 52, and the other end of the guide rod 53 penetrates through the top of the fixed frame 51, and the spring 54 is sleeved on the guide rod 53;
[0022] The second pushing mechanism 7 includes a second double-shaft motor 71, a screw rod 72 and a screw rod sleeve 73, the output end of the second double-shaft motor 71 is connected with the screw rod 72, the screw rod 72 is threadedly connected with the screw rod sleeve 73, and the bottom of the screw rod sleeve 73 is connected with the top of the fixed frame 51;
[0023] There are two screw rods 72, and the thread directions of the two screw rods 72 are opposite, so as to drive the two scraping mechanisms 5 to move synchronously towards the direction close to the coke oven body 9;
[0024] In the above technical solution, the second dual-shaft motor 71 drives the lead screw 72 to rotate, thereby driving the lead screw sleeve 73 to move, which in turn drives the two scraping mechanisms 5 to move synchronously towards the coke oven body 9. The movement of the scraping mechanism 5 drives the scraper 52 to push the metallurgical coke on the upper surface of the feeding mechanism 4 to move.
[0025] The feeding mechanism 4 includes a fixed plate 41, a vertical plate 42, a weighing device body 43, a slide rod 44, a moving plate 45, and a hinge rod 46. The vertical plate 42 is fixed to one top end of the fixed plate 41, the slide rod 44 is connected to one side of the vertical plate 42, and a mounting plate is hinged to the top of the vertical plate 42. The weighing device body 43 is set on the top of the mounting plate, a sliding sleeve is fitted on the slide rod 44, one end of the moving plate 45 is connected to the top of the sliding sleeve, one end of the hinge rod 46 is hinged to the moving plate 45, and the other end is hinged to the bottom of the mounting plate.
[0026] The weighing device body 43 adopts the weighing device body in CN202320089937.5. Its specific structure and weighing principle are existing technologies and will not be described in detail here.
[0027] The first pushing mechanism 6 includes a first dual-axis motor 61, a screw 62 and a movable sleeve 63. The output end of the first dual-axis motor 61 is connected to the screw 62. The screw 62 is threadedly connected to the movable sleeve 63. The movable sleeve 63 is connected to the moving plate 45.

[0029] The first dual-axis motor 61 drives the screw 62 to rotate, thereby moving the movable sleeve 63, which in turn drives the moving plate 45 to push the hinge rod 46. The hinge rod 46 pushes one end of the mounting plate upward, thereby tilting the upper surface of the weighing device body 43, and thus causing the metallurgical coke to move and slide.
[0030] The top plate 3 and the movable sleeve 63 both penetrate the fixed frame 51. The guide rod 53 and the spring 54 are located on both sides of the top plate 3 and the movable sleeve 63, which helps to ensure that the movement of the fixed frame 51 is not interfered with by the top plate 3 and the movable sleeve 63.
