Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically to a pebble crushing device. Background Technology

[0002] In the processing of pebbles as raw and auxiliary materials, crushing devices are required to crush the pebbles. Most existing crushing devices are jaw crushers, which consist of two jaw plates, a moving jaw and a stationary jaw, forming a crushing chamber. When in use, the pebbles are placed between the moving jaw and the stationary jaw.

[0003] However, during the operation of a jaw crusher, the distance between the moving jaw and the stationary jaw needs to be continuously adjusted. This is primarily to control the output particle size and ensure crushing efficiency and high-efficiency operation of the equipment. Specifically, the distance between the moving jaw and the stationary jaw directly affects the size of the discharge opening, thereby controlling the particle size of the crushed material. If the discharge opening is too large, the crushed material will be too large, potentially making it difficult for subsequent processing equipment to handle; if the discharge opening is too small, it will increase the equipment load and may even cause the equipment to idle, wasting resources. Adjusting the moving jaw and stationary jaw often requires manual adjustment of the screw, a cumbersome and inconvenient process. Therefore, we propose a pebble crushing device.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 4 This utility model provides a technical solution: a pebble crushing device, including a body 23, within which are a static crushing unit and a dynamic crushing unit. For example... Figure 1 As shown, the static alligator group and the dynamic alligator group are arranged in a "V" shape. The static alligator group includes a static alligator mounting body 15 installed in the body 23, and a static alligator plate 14 is detachably provided on the surface of the static alligator mounting body 15. The dynamic alligator group includes a dynamic alligator mounting body 10, and a dynamic alligator plate 9 is detachably provided on the surface of the dynamic alligator mounting body 10. In the actual installation process, the dynamic alligator plate 9 and the static alligator plate 14 are fastened to the surfaces of the dynamic alligator mounting body 10 and the static alligator mounting body 15 respectively by bolts.

[0023] like Figure 1 As shown, the bottom of the machine body 23 is mounted on the support base 1. A discharge port 16 is located on the support base 1 near the bottom outlets of the static and dynamic alligator groups, serving to discharge materials. The top of the dynamic alligator mounting body 10 is connected to the drive device, as shown... Figure 1As shown, the specific structure of the drive device includes a crankshaft 7 rotatably mounted on the top of the moving alligator mounting body 10, with both ends of the crankshaft 7 rotatably connected to the body 23. A belt flywheel 8 is provided on one end of the crankshaft 7, and an energy storage flywheel is installed on the other end of the crankshaft 7. The belt flywheel 8 is connected to a pulley via a belt, and the pulley is mounted on a drive motor 5. The drive motor 5 is mounted on a support base 1. When the drive motor 5 rotates, it can drive the crankshaft 7 to rotate through the belt flywheel 8, thereby causing the crankshaft 7 to drive the moving alligator assembly.

[0024] Furthermore, at least one elbow plate 13 is rotatably provided at the lower end of the side of the moving alligator mount 10 away from the moving alligator plate 9. When the number of elbow plates 13 is ≥2, the elbow plates 13 are symmetrically arranged. During installation, the end of the elbow plate 13 away from the moving alligator plate 9 is rotatably connected to the mounting beam 11. At least one tie rod 2 is rotatably provided on the moving alligator mount 10 below the elbow plate 13. Similar to the elbow plate 13, when the number of tie rods 2 is ≥2, the tie rods 2 are also symmetrically arranged. During installation, the end of the tie rod 2 away from the moving alligator plate 9 is connected to the mounting beam 11 through a tensioning assembly. Figure 2 As shown, the tensioning assembly includes a support plate 21, a tie rod 2 is vertically and movably placed inside the support plate 21, and the two sides of the support plate 21 are rotatably connected to the support 22 respectively. The support 22 is installed below the mounting beam 11.

[0025] A pressure plate 19 is detachably provided at the end of the pull rod 2 away from the moving alligator mounting body 10. Specifically, an external thread structure is provided at the end of the pull rod 2, and multiple nuts are provided on the pull rod 2. The nuts fix the pressure plate 19. A support spring 20 is sleeved on the pull rod 2 between the pressure plate 19 and the support plate 21. Therefore, the tension of the support spring 20 can be adjusted by adjusting the pressure of the nuts on the pressure plate.

[0026] The specific movement process is as follows: when the crankshaft 7 rotates, the moving jaw 9 moves towards the stationary jaw 14 along with the crankshaft 7. The bottom of the moving jaw mounting body 10 is supported by the elbow plate 13, and the set tie rod is used to control the movement of the moving jaw, ensuring that the material is uniformly crushed and split in the crushing chamber.

[0027] Furthermore, both ends of the mounting beam 11 are slidably connected to the body 23 via sliding components, the sliding components including slide blocks 17 respectively mounted at both ends of the mounting beam 11. Figure 2 and Figure 3 As shown, mounting plates 12 are provided at both ends of the mounting beam 11. The mounting plates 12 are detachably connected to the body 23. Specifically, the mounting plates 12 are fastened to the body 23 with bolts. Two strip-shaped limiting seats 3 are vertically mounted on the surface of the mounting plates 12. A limiting groove is formed between the two strip-shaped limiting seats 3. The slide 17 is placed in the limiting groove and can reciprocate along the limiting groove.

[0028] Multiple support wheels are installed on the upper and lower end faces of the slide 17 and on the side of the slide 17 away from the mounting beam 11. The support wheels contact the strip-shaped limiting seat 3 and the mounting plate 12 respectively. The support wheels can convert the sliding friction between the slide 17 and the strip-shaped limiting seat 3 into rolling friction, reducing the sliding resistance of the slide 17. Figure 4 As shown, the specific structure of the support wheel includes a support shaft 24, on which at least one support bearing is mounted. Both ends of the support shaft 24 are placed inside the U-shaped seat 6, which is fixed on the slide 17. Both ends of the support shaft 24 are fastened by fasteners, which are nuts threaded onto both ends of the support shaft 24.

[0029] The support bearing has good support performance and high support strength. After the support bearing is installed on the support shaft 24, the two ends of the support shaft 24 are placed in the U-shaped seat 6 and then fixed with nuts, which facilitates the disassembly and installation of multiple support bearings.

[0030] Furthermore, a telescopic device parallel to the sliding assembly is installed at at least one end of the mounting beam 11. This telescopic device moves the mounting beam 11 closer to or further away from the stationary assembly. Figure 4 As shown, the telescopic device can be installed at both ends of the mounting beam 11, or it can be installed at one end of the mounting beam 11. The telescopic device includes a drive hydraulic cylinder 4 rotatably mounted on the end of the slide block 17 away from the elbow plate 13. The other end of the drive hydraulic cylinder 4 is rotatably connected to the mounting base 18, which is mounted on the mounting plate 12.

[0031] Based on the above embodiments, it should be noted that when the moving alligator plate 9 moves, if it is found that the gap between the moving alligator plate 9 and the stationary alligator plate 14 is too small or too large, the drive hydraulic cylinder 4 can be controlled to extend or retract, so that the drive hydraulic cylinder 4 drives the mounting beam 11 to move towards or away from the stationary alligator plate 14, thereby changing the distance between the moving alligator plate 9 and the stationary alligator plate 14, so that the distance between the moving alligator plate 9 and the stationary alligator plate 14 can be changed at any time.

[0032] Based on the above embodiments, further optimizations can be made, such as... Figure 2 and Figure 3 As shown, the strip-shaped limiting seat 3 and the mounting plate 12 are connected by multiple triangular reinforcing seats, which can improve the support strength of the strip-shaped limiting seat 3.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
