Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically a jaw crusher with a protective structure. Background Technology

[0002] Jaw crushers, also known as jaw breakers or tiger's mouth crushers, consist of a crushing chamber formed by two jaw plates: a moving jaw and a stationary jaw. They mimic the jaw movements of an animal to crush materials. They are widely used in the crushing of various ores and large materials in industries such as mining, metallurgy, building materials, highways, railways, water conservancy, and chemicals.

[0003] Currently, most jaw crushers used in mines rely on mechanical or manual feeding of materials into the crusher from the top inlet for crushing. However, most existing crushers lack protective structures, which can easily cause debris to fly when crushing harder rocks or minerals. This can lead to accidental injury to nearby workers, increasing work risks and resulting in poor equipment usability. Utility Model Content

[0004] The purpose of this utility model is to provide a jaw crusher with a protective structure to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a jaw crusher with a protective structure, including a mounting box, a first crushing plate fixedly installed inside the mounting box, a top cover slidably installed at the upper end of the mounting box, a mounting frame rotatably installed at the side end of the top cover, a protective cover rotatably installed on the outer surface of the mounting frame, a rotating motor installed inside the mounting box, two rotating disks rotatably installed at the side end of the rotating motor, and the same second crushing plate slidably installed at the side end of each rotating disk.

[0005] More preferably, the lower end of the mounting box is fixedly installed with a support leg, the upper end of the mounting box is fixedly installed with four fixing blocks, and the inner walls on both the left and right sides of the mounting box are provided with sliding grooves.

[0006] More preferably, a connecting ring is fixedly installed on the side end of the mounting frame, and the mounting frame is rotatably installed on the side end of the cap by cooperating with the protrusions on both sides of the cap through the connecting ring.

[0027] The usage and advantages of this utility model: The jaw crusher with a protective structure operates as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when using the device, the user first places it on a horizontal surface. The user then picks up the mounting box 1 and installs the support legs 11 below it. Four fixing blocks 12 are then installed on top of the mounting box 1. Next, the first breaking plate 13 is installed inside the mounting box 1. Then, the user picks up the mounting frame 2 and installs two connecting rings 21 on the side of the frame 2. The connecting rings 21 are then connected to the protrusions on both sides of the top cover 15 through the internal openings. The top cover 15 is then installed on the side of the mounting frame 2. Finally, a protective cover 22 is installed on the outer surface of the mounting frame 2. A transparent baffle 23 is installed inside the protective cover 22, and a fixing handle 24 is installed on the side of the protective cover 22. Then, the assembled mounting frame 2 is installed above the mounting box 1 along the opening below the top cover 15 and the fixing block 12. Then, the rotating motor 3 is picked up, and rotating rods 31 are installed on both sides of the rotating motor 3. A transmission belt 32 is installed on the outer surface of the rotating rod 31, and connecting rods 33 are installed on the side ends of the two transmission belts 32. Rotating disks 34 are installed on the side ends of the two connecting rods 33, and pushing rods 35 are installed on the side ends of the two rotating disks 34. Then, the second crushing plate is picked up. 37. Two fixing rings 36 are installed on the side of the second crushing plate 37. Upper limit blocks 38 are installed on the left and right sides of the second crushing plate 37. Then, the two fixing rings 36 are connected to the push rod 35. Then, the assembled rotating motor 3 and other parts are placed into the mounting box 1. The two limit blocks 38 are installed into the sliding groove 14 opened inside the mounting box 1. When the user needs to use the device, the user picks up the material to be crushed and pulls the fixing handle 24. The fixing handle 24 drives the protective cover 22 to rotate along the connecting ring 21, thereby opening the upper opening. After opening the box and putting the material into the installation box 1, the user pulls the fixed handle 24 to reset the protective cover 22. Then, the rotating motor 3 is started. The rotating motor 3 drives the rotating rod 31 to rotate, which in turn drives the transmission belt 32 to rotate the connecting rod 33. When the connecting rod 33 rotates, it drives the rotating disk 34 to rotate. After rotation, it pushes the push rod 35 to move, which in turn works with the upper limit block 38 and the slide 14 to limit the movement. This causes the second crushing plate 37 to move repeatedly to adjust the distance between it and the first crushing plate 13, thereby quickly crushing the material.
