Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a moving jaw support mechanism for a jaw crusher. Background Technology

[0002] Jaw crushers, also known as jaw crushers or simply jaw breakers, are mainly used for medium-sized crushing of various ores and large materials. They are widely used in mining, metallurgy, building materials, highways, railways, water conservancy, and chemical industries. Their performance characteristics include a large crushing ratio, uniform product particle size, simple structure, and reliable performance. In existing jaw crushers, the back side of the moving jaw is connected to an adjusting seat via an toggle plate. The toggle plate supports the moving jaw. When the eccentric shaft drives the moving jaw, the two ends of the toggle plate rotate relative to the toggle plate seat located on the moving jaw and the adjusting seat, generating friction. After prolonged use, the toggle plate wears significantly. This application provides a mechanism that replaces the toggle plate to support the back side of the moving jaw. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a jaw crusher motor jaw support mechanism to address the above-mentioned technical deficiencies.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a moving jaw support mechanism for a jaw crusher, including an adjusting seat, an intermediate plate provided on the side of the adjusting seat near the moving jaw, a support frame provided on the side of the intermediate plate away from the adjusting seat, and a plurality of rollers rotatably connected to the side of the support frame away from the intermediate plate.

[0005] Preferably, the side of the adjustment seat away from the middle plate is provided with an inclined surface, which is inclined in the direction away from the middle plate from bottom to top.

[0006] Preferably, the intermediate plate is provided with multiple weight reduction holes.

[0007] Preferably, the intermediate plate is detachably connected to the adjustment seat and the support frame, respectively.

[0008] Preferably, vertical plates are provided on both sides of the intermediate plate, and multiple through holes are provided on the vertical plates. Multiple threaded holes are provided on the adjusting seat and the support frame.

[0009] The beneficial effects of this utility model are: the adjusting seat is connected in sequence with an intermediate plate and a support frame, and multiple rollers are rotatably connected on the support frame. After the support mechanism of this application is installed on the jaw crusher, the rollers support the back side of the moving jaw. When the moving jaw and the rollers move relative to each other, the rollers will rotate passively, thus reducing wear. Attached Figure Description

[0014] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0015] Detailed implementation method: combined with Figures 1-2 As shown, a moving jaw support mechanism 7 for a jaw crusher includes an adjusting seat 71. An intermediate plate 72 is provided on the side of the adjusting seat 71 near the moving jaw 4. A support frame 73 is provided on the side of the intermediate plate 72 away from the adjusting seat 71. Multiple rollers 731 are rotatably connected to the side of the support frame 73 away from the intermediate plate 72. Multiple sets of ear plate pairs can be provided on the side of the support frame 73 away from the intermediate plate 72. A shaft is provided between each set of ear plate pairs. The rollers 731 (with bearings installed in their inner holes) are rotatably connected to the shaft. The rollers 731 can also be bearings. After installing the support mechanism 7 of this application on a jaw crusher, combined with... Figure 2As shown, the jaw crusher includes a housing 1. A fixed jaw plate 5 is located on one side inside the housing 1. An eccentric shaft 3 is rotatably connected to the housing 1. A pulley 2 for motor drive is located at the end of the eccentric shaft 3. The upper part of the movable jaw 4 is rotatably connected to the eccentric shaft 3 (a bearing, not shown in the figure, is provided between them). A movable jaw plate 6 is located on one side of the movable jaw 4. An adjusting seat 71 is slidably connected to the housing 1. The rear of the housing 1 also has an adjusting mechanism for adjusting the position of the adjusting seat 71 to adjust the discharge opening width, and a tensioning mechanism 9 for pulling the movable jaw 4 so that its back side contacts the roller 731. The part of the movable jaw 4 that contacts the roller 731 has a flat surface. When the crusher is working, as the movable jaw 4 moves under the action of the eccentric shaft 3, the roller 731 is always in contact with the back side of the movable jaw 4 and passively rotates, thus minimizing wear. The intermediate plate 72 has a slightly lower strength so that when uncrushable materials or debris are encountered, it will break first to protect other components from damage.

[0016] In this embodiment, the adjustment mechanism includes a lifting wedge 8. The side of the lifting wedge 8 closest to the adjustment seat 71 is inclined away from the adjustment seat 71 in the direction from bottom to top. Lifting bolts are provided on both sides of the housing 1. The lifting bolts are connected to the lifting wedge 8. By rotating the nut on the lifting bolt, the up and down position of the lifting bolt can be adjusted, thereby adjusting the up and down position of the lifting wedge 8. In this case, the side of the adjustment seat 71 away from the intermediate plate 72 is provided with an inclined surface. The inclined surface is inclined away from the intermediate plate 72 in the direction from bottom to top. The inclined surface cooperates with the lifting wedge 8. When the lifting wedge 8 rises, the adjustment seat 71 will move towards the moving jaw 4, thereby reducing the width of the discharge port.

[0017] In this embodiment, the intermediate plate 72 is provided with multiple weight reduction holes.

[0018] In this embodiment, the intermediate plate 72 is detachably connected to the adjustment seat 71 and the support frame 73 respectively. When the intermediate plate 72 is broken, only the intermediate plate 72 can be replaced, thereby reducing costs.

[0019] In this embodiment, vertical plates are provided on both sides of the intermediate plate 72, and multiple through holes are provided on the vertical plates. Multiple threaded holes are provided on the adjusting seat 71 and the support frame 73. Bolts are passed through the through holes and connected to the threaded holes, so that the three can be connected together.

[0020] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
