Description

Technical Field

[0001] This utility model relates to the field of jaw plate frames, specifically a jaw plate frame with a reinforced structure. Background Technology

[0002] Jaw plates are core, easily worn components of jaw crushers, divided into moving jaw plates and stationary jaw plates. They are widely used in material crushing operations in mining, building materials, and other fields. Their models and dimensions are matched to the crusher type. They are primarily made of high-manganese steel, with water-cooling treatment to improve wear resistance. Some new composite materials (such as manganese-chromium alloys and bimetallic composites) can extend the service life to more than three times that of ordinary products. This component applies a crushing action to materials through the meshing structure of tooth peaks against tooth valleys. The tooth angle and spacing design optimizes crushing efficiency. Small and medium-sized jaw plates use a symmetrical design for reversible use, while large equipment uses a modular, segmented structure for easy partial replacement. During assembly, soft metal shims are used for fixing, and spring anti-loosening devices reduce the risk of bolt breakage.

[0003] The jaw plate frame (or jaw seat, jaw bed) is the core support structure of a jaw crusher, used to fix and support the jaw plates (such as the fixed jaw plate and the moving jaw plate), ensuring their stable operation during material crushing. This component is usually made of cast steel or cast iron, possessing high strength characteristics to withstand the enormous reaction forces and impact loads during the crushing process. Existing jaw plate frames have low adjustability and poor adaptability to handling materials of different sizes, necessitating a new type of jaw plate frame. Utility Model Content

[0004] The purpose of this invention is to provide a jaw plate frame with a reinforced structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: slide rails are provided on the front and rear sides of the fixed plate, the reinforcing rib is installed on the left side of the fixed plate, and a stud is installed on the left side of the reinforcing rib. A fastening nut is installed in the middle of the periphery of the stud, and the fastening nut is threadedly connected to the stud. The reinforcing ribs installed on the fixed plate and the moving plate can effectively enhance the strength of the fixed plate, enhance the resistance to the huge reaction force and impact load from the jaw plate, and improve the structural strength.

[0006] Preferably, an adjusting nut is threadedly connected to the left side of the stud, and a ball joint is installed on the left side of the adjusting nut. By tightening the nut and rotating it, the adjusting nut is tightened to prevent vibration from causing loosening.

[0007] Preferably, the slide rail has a slider internally slidably connected, and the inner side of the slider is rotatably connected to a rotating shaft. Rotating the lead screw drives the slider to slide in the slide rail to a suitable position, which facilitates the adjustment of the distance between the fixed plate and the moving plate.

[0008] Preferably, a lead screw is rotatably connected to the right side of the slider, and a second fastening nut is threaded onto the outer side of the lead screw. The second fastening nut is rotated to press against one side of the slide rail to prevent the lead screw from loosening.

[0009] Preferably, a movable plate is installed on one side of the rotating shaft one, and a rotating shaft two is installed on the upper right side of the movable plate.

[0010] Preferably, a rotating frame is installed on the periphery of the second rotating shaft, and the rotating frame is rotatably connected to the second rotating shaft.

[0011] Preferably, an adjustment component is installed on the right side of the rotating frame, and the adjustment component is embedded in the rotating frame.

[0012] Preferably, the adjustment assembly includes an adjustment frame and bolts, and the bolts are installed inside the adjustment frame. The adjustment frame is fixed to the openings at different positions on the rotating frame by the bolts, thereby changing the overall length of the rotating frame and the adjustment frame, and thus changing the amplitude of the reciprocating motion of the moving plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Reinforcing ribs are installed on the fixed plate and the moving plate, which effectively enhances the strength of the fixed plate, strengthens its resistance to the huge reaction force and impact load from the jaw plate, and improves structural strength. After the jaw plate is installed on the fixed plate and the moving plate, the length of the stud extension is changed by rotating the adjusting nut, and the adjusting nut is tightened by rotating the fastening nut to prevent loosening due to vibration. Four sets of ball joints facilitate adjustment, thereby aligning the jaw plates on the fixed plate and the moving plate to prevent uneven force during crushing, which would reduce service life. The rotating screw drives the slider to slide to a suitable position in the slide rail, and then the fastening nut is tightened by rotating the fastening nut to one side of the slide rail to prevent the screw from loosening, facilitating the adjustment of the distance between the fixed plate and the moving plate. The lower end of the moving plate rotates via a rotating shaft, and the adjusting frame is installed on the eccentric shaft of the crusher. The rotating frame on the rotating shaft drives the moving plate to reciprocate and compress the material. The adjusting frame is fixed to the openings at different positions on the rotating frame by bolts, thereby changing the overall length of the rotating frame and the adjusting frame, thus changing the amplitude of the reciprocating motion of the moving plate, facilitating adjustment.
