[0024] Specific examples are given below.

[0025] See also Figure 1-Figure 4The utility model provides a coking coal production safety automatic control device, comprising a box body 1: a feed port 3 is fixed at the top of the box body 1; a controller 2 is fixed at one end of the top of the box body 1 close to the feed port 3; a discharge port is opened at the lower end of the end of the box body 1 away from the feed port 3; a shell 4 is fixed at the top of one side of the box body 1; a crushing assembly is arranged at the inner side of the box body 1 and below the feed port 3, which is used to crush large pieces of coal; a conveying assembly is arranged at the inner side of the box body 1 and below the crushing assembly; a baffle plate 12 is arranged at the inner side of the discharge port; one end of the baffle plate 12 is rotatably connected to the box body 1; an adjustment assembly is arranged at the inner side of the box body 1 and at a position corresponding to the baffle plate 12; and it is used to adjust the opening angle of the baffle plate 12. When working, firstly, coal is fed into the inner side of the box body 1 through the feed port 3. Subsequently, the larger coal is crushed by the crushing assembly to facilitate the subsequent coking process. The crushed coal enters the discharge port through the conveying assembly, and then the opening angle of the baffle plate 12 is adjusted by the adjusting assembly to control the discharge amount. This step is achieved through the coordinated structural design of the adjusting assembly and the baffle plate 12, so that when the discharge amount of the coal needs to be controlled, the opening angle of the baffle plate 12 is adjusted by the adjusting assembly to control the size of the discharge port, thereby controlling the discharge amount of the coal, improving the control degree of the amount of coal put in during coking, improving the quality of coking, and improving the practicality of the device;

[0026] Further, such as Figure 3 and Figure 4As shown, the adjustment assembly includes a transmission screw 13; the transmission screw 13 is arranged on the inner side of the box body 1 and is located at the two ends of the baffle plate 12; the transmission screw 13 is rotatably connected to the box body 1; the end of the transmission screw 13 close to the baffle plate 12 is threadedly connected with a built-in threaded rod 14; the end of the built-in threaded rod 14 away from the transmission screw 13 is fixed with a connecting block 15; slide grooves 17 are provided on both sides of the baffle plate 12 and at positions corresponding to the connecting block 15; a connecting slider 16 is provided on the inner side of the slide groove 17; the connecting slider 16 is slidably connected to the baffle plate 12 through the slide groove 17; the connecting slider 16 is rotatably connected to the connecting block 15. During operation, when the transmission screw 13 rotates, it drives the built-in threaded rod 14 threadedly connected to it to move. When the built-in threaded rod 14 moves, the connecting slider 16 is driven to move at the same time through the connecting block 15. Because the connecting slider 16 is slidably connected to the baffle plate 12, one end of the baffle plate 12 is rotatably connected to the box body 1, so that when the connecting slider 16 moves, it can drive the baffle plate 12 to perform a circular motion, thereby adjusting the angle of the baffle plate 12 and controlling the discharging speed. This step can be achieved through the coordinated structural design of the transmission screw 13, the built-in threaded rod 14, the connecting block 15 and the connecting slider 16, so that when the transmission screw 13 rotates, the connecting slider 16 can be driven to move through the built-in threaded rod 14 and the connecting block 15, so that when the connecting slider 16 moves, the baffle plate 12 is driven to perform a circular motion, and then the opening angle of the baffle plate 12 can be adjusted to achieve the control of the discharging speed.

[0027] Further, such as Figure 3 and Figure 4 As shown, a first bevel gear 19 is fixed to one end of the transmission screw 13 away from the built-in threaded rod 14; a transmission rod 18 is rotatably connected to the inner side of one end of the box body 1 close to the material blocking plate 12; second bevel gears 20 are fixed to both ends of the transmission rod 18; the second bevel gear 20 is meshed and connected with the first bevel gear 19; a driving assembly is provided at a position corresponding to the transmission rod 18 on the inner side of the box body 1. During operation, when the transmission rod 18 rotates, the transmission rod 18 drives the second bevel gear 20 to rotate, and when the second bevel gear 20 rotates, the transmission screw 13 is driven to rotate through the first bevel gear 19 meshed and connected therewith. This step can be achieved through the matching structure design of the second bevel gear 20 and the first bevel gear 19, so that when the transmission rod 18 rotates, the transmission screw 13 can be driven to rotate simultaneously through the transmission rod 18 and the first bevel gear 19.

[0028] like Figure 3 and Figure 4As shown, the driving assembly includes a second motor 23; the second motor 23 is fixed on the inner side of the box body 1; a driving worm 22 is fixed on the output end of the second motor 23; a driving worm wheel 21 is fixed at the position of the transmission rod 18 corresponding to the driving worm 22; and the driving worm wheel 21 is meshedly connected with the driving worm 22. During operation, when it is necessary to adjust the baffle plate 12, the second motor 23 is first controlled to start by the controller 2, and the second motor 23 drives the driving worm 22 to rotate. When the driving worm 22 rotates, the driving rod 18 is driven to rotate through the driving worm wheel 21 meshed with it. This step can be effectively designed through the matching structure of the driving worm 22 and the driving worm wheel 21, so that when the second motor 23 is started, the driving worm 22 and the driving worm wheel 21 can drive the transmission rod 18 to rotate, thereby providing power for the rotation of the transmission rod 18.

[0029] like Figure 2 As shown, the crushing assembly includes two crushing rollers 5; the two crushing rollers 5 are respectively arranged inside the box 1 and below the feed port 3; one end of the crushing roller 5 extends to the inside of the shell 4; the two crushing rollers 5 are fixed with a transmission gear 7 at one end of the inner side of the shell 4; the two transmission gears 7 are meshed and connected; a first motor 6 is fixed inside the shell 4; the output end of the first motor 6 is fixedly connected to one of the crushing rollers 5. During operation, when it is necessary to enter the inner side of the box 1 from the feed port 3, the first motor 6 is first started by the controller 2, and then the first motor 6 drives the crushing roller 5 fixed thereto to rotate, and at the same time, the other crushing roller 5 is driven to rotate at the same time through the two mutually meshing transmission gears 7, so that the larger coal can be crushed. In this step, the structural design of the crushing roller 5 enables the larger coal to be crushed when the uncoked coal is placed inside the box 1, thereby reducing the difference in coking quality caused by the large difference in coal volume during subsequent coking of the coal, effectively improving the overall quality of coking and improving the practicality of the device.

[0030] like Figure 2 As shown, the conveying assembly includes a conveyor belt 8; the conveyor belt 8 is arranged inside the box 1 and below the crushing roller 5; the inner sides of both ends of the conveyor belt 8 are rotatably connected with rotating rollers 10; and baffles 9 are fixed on both sides of the conveyor belt 8. During operation, when the crushed coal falls downward, it will fall to the top of the conveyor belt 8. At this time, the rotating roller 10 rotates, so that the coal at the top of the conveyor belt 8 can be transported to the position of the discharge port. This step can transport the crushed coal, avoid the problem of blockage caused by a large amount of coal accumulation, and improve the efficiency of discharging.

[0031] like Figure 2As shown, one end of one of the rotating rollers 10 is connected to the output end of the first motor 6 through a transmission belt 11. During operation, when the first motor 6 is started, the rotating roller 10 is driven to rotate through the transmission belt 11. This step can be achieved through the structural design of the transmission belt 11, so that when the first motor 6 is started, the rotating roller 10 can be driven to rotate through the transmission belt 11 at the same time, thereby driving the conveyor belt 8 to follow the crushing roller 5 to work simultaneously.

[0032] Working principle: when the coal needs to be fed from the feed port 3 into the inner side of the box body 1, the first motor 6 is first started through the controller 2, and then the first motor 6 drives the crushing roller 5 fixed thereto to rotate, and at the same time drives the other crushing roller 5 to rotate at the same time through two mutually meshing transmission gears 7, so that the larger coal can be crushed; when the crushed coal falls downward, it will fall to the top of the conveyor belt 8, and at this time the rotating roller 10 rotates, so that the coal at the top of the conveyor belt 8 can be transported to the position of the discharge port; then the opening angle of the baffle plate 12 is adjusted through the adjustment component, so as to control the discharge amount. When the baffle plate 12 needs to be adjusted, the second motor 23 is first started through the controller 2, and the second motor 23 drives the driving worm 22 Rotate, when the driving worm 22 rotates, it drives the transmission rod 18 to rotate through the driving worm gear 21 meshing with it. When the transmission rod 18 rotates, the transmission rod 18 drives the second bevel gear 20 to rotate. When the second bevel gear 20 rotates, it drives the transmission screw 13 to rotate through the first bevel gear 19 meshing with it. When the transmission screw 13 rotates, it drives the built-in threaded rod 14 threadedly connected to it to move. When the built-in threaded rod 14 moves, the connecting slider 16 is driven to move at the same time through the connecting block 15. Because the connecting slider 16 is slidingly connected to the baffle plate 12, one end of the baffle plate 12 is rotatably connected to the box body 1, so that when the connecting slider 16 moves, it can drive the baffle plate 12 to perform a circular motion, thereby adjusting the angle of the baffle plate 12 and controlling the discharge speed.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
