Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-3 , the utility model provides an embodiment: a small coke oven execution mechanism, including a base 8, the top four corners of the base 8 are fixedly connected with support rods 12, which are used to install and support the fixed bracket, the top of the support rod 12 is fixedly connected with a fixed bracket 10, the inner side of the fixed bracket 10 is hollow, which is convenient for the translation platform 4 to move, and the right end of the inner side of the fixed bracket 10 is fixed with a stepper motor 1, which is steadily driven by a high-precision digital stepper driver at a speed of 7.1mm / s, and is the driving source for the translation platform 4 in the device, the output end of the stepper motor 1 is fixedly connected with a liquid ball screw 2, the external thread of the liquid ball screw 2 is connected with an L-shaped connecting plate 3, and the top of the L-shaped connecting plate 3 is fixedly connected with the translation platform 4, starting the stepper motor 1 to run, thereby driving the liquid The ball screw 2 moves, which in turn can drive the translation platform 4 to move. The top of the translation platform 4 is fixedly connected to a worm gear reduction motor 5, which is operated by an operator with a handheld remote control and can be safely operated from a long distance to realize the movement of the coal retort in and out of the furnace. The output end of the worm gear reduction motor 5 is meshingly connected to a worm 6, and the bottom end of the worm 6 is fixedly connected to a lifting platform 7. The top left side of the lifting platform 7 is fixedly connected to a servo motor 14, and the output end of the servo motor 14 is fixedly threadedly connected to a threaded rod 15, and the bottom end of the threaded rod 15 is fixedly connected to a tamping plate 13. By starting the servo motor 14, the tamping plate 13 can be driven up and down to tamp the coal material. The bottom right side of the lifting platform 7 is fixedly connected to a sealing plate 16, which can be connected to the coal retort 9 so that it can be placed inside the coke oven.

[0026] A coal retort 9 is fixedly connected to the left side of the top of the base 8 for tamping the coal material, and a coke oven 11 is fixedly connected to the right side of the top of the base 8 for coking the coal material. The front and rear sides of the bottom end of the translation platform 4 are slidably connected to the front and rear side through grooves of the top of the fixed bracket 10, thereby ensuring the movement stability of the translation platform 4. The outer part of the liquid ball screw 2 is rotatably connected to the inner rear end of the fixed bracket 10, so that the screw 2 can rotate normally, thereby driving the lifting platform 7 to move up and down.

After the coal is tamped, the stepper motor 1 can be started to drive the translation platform 4 to move, and at the same time drive the sealing plate 16 to move. When the sealing plate 16 moves to the position above the coal retort, the stepper motor 1 is turned off, and the turbine reduction motor 5 is started to drive the sealing plate 16 to move downward to connect it with the coal retort. After the connection is completed, the coal retort is driven to rise and fall again through the action of the worm gear reduction motor 5. Thereafter, the stepper motor 1 is started to move the coal retort to the coke oven position and put it into the coke oven, so that the coal can be coked inside the coke oven.
