Description

Technical Field

[0001] This utility model relates to the field of coal conveying technology, specifically a conveying device for coal preparation. Background Technology

[0002] Before packaging and transporting coal, it is necessary to sort and select coal of different sizes and specifications. However, manual screening is labor-intensive, time-consuming, and inefficient. Therefore, coal sorting equipment is used to transport and screen the coal.

[0003] The existing utility model with authorization announcement number CN220514783U discloses a coal preparation conveying device, including a base plate, a vertical plate fixedly connected to the back of the base plate, two symmetrical synchronous pulleys rotatably arranged on the front of the vertical plate, a synchronous belt wound between the two synchronous pulleys through tooth grooves, and a rotating component for rotating one of the synchronous pulleys is provided on the vertical plate. Multiple concave push plates are fixedly arranged on the surface of the synchronous belt at equal intervals and located directly above the base plate.

[0004] The above technical solution, due to the different spacing between each pair of rotating rollers, allows coal to fall at the corresponding position according to its size, achieving the effect of sorting and avoiding manual coal sorting operations, thus achieving high efficiency. However, when conveying large quantities of coal, the above technical solution may cause small coal pieces to be carried along by large coal pieces, preventing the coal from being separated. This results in small coal pieces being conveyed and screened into the large coal collection box, leading to poor coal screening effect and requiring manual secondary screening and conveying, thereby reducing the screening efficiency of the conveying equipment used for coal preparation.

[0005] Therefore, those skilled in the art have provided a conveying device for coal preparation to solve the problems mentioned in the background art. Utility Model Content

[0023] Please see Figure 1-4A coal preparation conveying device includes a conveying base plate 1, and a screening conveying mechanism 2 is arranged above the conveying base plate 1.

[0024] The screening and conveying mechanism 2 includes a screening and conveying frame 201. The bottom surface of the screening and conveying frame 201 is fixedly connected to the upper surface of the conveying base plate 1. A support frame 3 is fixedly connected to the left side of the screening and conveying frame 201. A conveying rotary motor 4 is fixedly connected to the upper surface of the support frame 3. By using the support frame 3, the conveying rotary motor 4 can be fixed to one side of the screening and conveying frame 201, so that the conveying rotary motor 4 can be used to provide power for the conveying equipment to transport coal.

[0025] The screening conveyor frame 201 is rotatably connected to a first screening conveyor belt 202, a second screening conveyor belt 203, and a third screening conveyor belt 204. The output end of the conveying motor 4 is fixedly connected to a drive rod 5, which is rotatably connected to the inside of the screening conveyor frame 201. Several driven rods 6 are rotatably connected to the inside of the screening conveyor frame 201. The outer surface of the drive rod 5 and the outer surface of one of the driven rods 6 are in contact with the inner wall of the first screening conveyor belt 202. The outer surfaces of the other two sets of driven rods 6 are in contact with the inner walls of the second screening conveyor belt 203 and the third screening conveyor belt 204, respectively. The drive rod 5 is driven to rotate by the conveying motor 4, which allows the drive rod 5 and multiple driven rods 6 to cooperate in driving the first screening conveyor belt 202, the second screening conveyor belt 203, and the third screening conveyor belt 204 to rotate inside the screening conveyor frame 201.

[0026] Two sets of driven rotating rods 6 are fixedly connected to the left end of rotating gears 7. Each set of rotating gears 7 has a gear belt 8 on its outer surface. Each set of rotating gears 7 meshes with the gear belt 8. By using the rotating gears 7 fixed at one end of the driven rotating rods 6, the two rotating gears 7 can be driven by the gear belt 8, so that the driving rotating rod 5 can easily drive multiple driven rotating rods 6 to rotate.

[0027] Both sides of the first screening conveyor belt 202, both sides of the second screening conveyor belt 203, and both sides of the third screening conveyor belt 204 are fixedly connected with blocking and limiting strips 205. The screening conveyor frame 201 is slidably connected with collection boxes 9 arranged at equal intervals. The bottom surface of each collection box 9 is in contact with the upper surface of the transport base plate 1. Multiple collection boxes 9 are arranged in sequence directly below the first screening conveyor belt 202, the second screening conveyor belt 203, and the third screening conveyor belt 204 to facilitate the classification and collection of coal screened off their surfaces.

[0028] The two sides of the screening conveyor frame 201 are fixedly connected with equally spaced fixed mounting frames 206. Each set of fixed mounting frames 206 has a support limiting ring 207 fixedly connected to its inner wall. Each collection box 9 has two limiting grooves 12 on its bottom surface. The upper surface of the transport base plate 1 has two sets of limiting slide bars 13. Each set of limiting slide bars 13 is slidably connected to the inside of the limiting groove 12. By using the limiting slide bars 13 to slide inside the limiting groove 12, the movement of the collection box 9 is limited, thereby improving the stability of pulling the collection box 9.

[0029] Each support limiting ring 207 is equipped with a vibration motor 209. The vibration motor 209 consists of an adjustable eccentric block mounted at each end of the rotor shaft. It utilizes the centrifugal force generated by the high-speed rotation of the shaft and eccentric blocks to obtain the excitation force. The model of the vibration motor 209 is YBZ-1005. A vibrating plate 208 is fixedly connected to the output end of each vibration motor 209. The bottom surface of each vibrating plate 208 is in contact with the upper surface of the support limiting ring 207. The upper surfaces of several vibrating plates 208 respectively contact the first screen... The inner walls of the first screening conveyor belt 202, the second screening conveyor belt 203, and the third screening conveyor belt 204 are in contact. Each collection box 9 has a pull plate 10 fixedly connected to its left side. The right side of each pull plate 10 is in contact with the left side of the transport base plate 1. Each pull plate 10 has a pull handle 11 fixedly connected to its left side. By manually holding the pull handle 11, the collection box 9 can be easily pulled using the pull plate 10, thereby facilitating the collection and processing of the coal screened out of the collection box 9.

[0030] The working principle of this utility model is as follows: In use, first connect the vibrating motor 209 and the conveying rotary motor 4 to the power supply. When using this coal preparation conveying equipment to transport and screen coal, first manually place the conveying equipment in the required position, and then manually hold the pull handle 11 to easily pull the collection box 9 using the pull plate 10. This allows the three collection boxes 9 to slide into the screening conveyor frame 201 until one side of the pull plate 10 contacts one side of the conveying base plate 1. This allows for convenient collection of coal of different particle sizes screened out using the three collection boxes 9. Next, by controlling the power supply of the vibrating motor 209 and the conveying rotary motor 4, the conveying rotary motor 4 fixed on the support frame 3 drives the active rotating rod 5 to rotate within the screening conveyor frame 201. Through the cooperation of the active rotating rod 5 and multiple driven rotating rods 6, and by using the rotating gear 7 fixed at one end of each of the two sets of driven rotating rods 6... The gear belts 8 are connected to facilitate the rotation of multiple driven rotating rods 6 by the rotation of the active rotating rod 5. This enables the first screening conveyor belt 202, the second screening conveyor belt 203, and the third screening conveyor belt 204 to rotate within the screening conveyor frame 201. Simultaneously, the support limiting ring 207 fixed by the fixed mounting bracket 206 facilitates the installation of the vibrating disc 208 and the vibrating motor 209 inside the first screening conveyor belt 202, the second screening conveyor belt 203, and the third screening conveyor belt 204. By controlling the power supply of the vibrating motor 209, the vibrating disc 208 vibrates, thus vibrating and screening the coal conveyed on the first screening conveyor belt 202, the second screening conveyor belt 203, and the third screening conveyor belt 204. The conveyed coal is sequentially collected in the collection box 9 according to the particle size range of the first screening conveyor belt 202, the second screening conveyor belt 203, and the third screening conveyor belt 204.
