[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0039] Refer to the attached Figure 2 and the attached Figure 3 and the attachedFigure 4 , an embodiment provided by the present utility model: a discharge port structure for a jaw crusher, including a machine body 1, a movable jaw plate 9 is fixedly connected to the middle of the machine body 1, a servo motor II 11 is fixedly connected to the outer wall of the machine body 1, a rotating rod 12 is fixedly connected to the output end of the servo motor II 11, a fixed jaw plate 13 is fixedly connected to the outer wall of the rotating rod 12, a movable plate 14 is fixedly connected to the top of the fixed jaw plate 13, sliding grooves 16 are respectively opened at the front and rear sides of the top of the machine body 1, both ends of the outer wall of the movable plate 14 are slidably connected to the inside of the sliding grooves 16, both ends of the outer wall of the movable plate 14 are fixedly connected with moving blocks 15, the adjacent sides of the two moving blocks 15 are both slidably connected to the outer wall of the machine body 1, a vibration assembly is arranged on the outer wall of the movable jaw plate 9, and an adjusting mechanism 2 is arranged at the bottom of the machine body 1; the vibration assembly includes a rotating shaft II 6, and the outer wall of the rotating shaft II 6 is fixedly connected to the inside of the movable jaw plate 9; a pulley II 7 is fixedly connected to the front side of the rotating shaft II 6, a servo motor I 3 is fixedly connected to the left side of the machine body 1, a rotating shaft I 4 is fixedly connected to the output end of the servo motor I 3, a pulley I 5 is fixedly connected to the outer wall of the rotating shaft I 4, and the pulley I 5 and the pulley II 7 are connected by a belt 8;

[0040] Specifically, the setting of the vibration assembly makes the movable jaw plate 9 vibrate, which helps the material to be broken more quickly and fully in the crushing cavity, improves the crushing efficiency, and at the same time promotes the smooth discharge of the crushed material, reducing blockage. By precisely controlling the position of the fixed jaw plate 13 through the servo motor II 11, the size of the discharge port can be accurately adjusted, so as to obtain the crushing particle size that meets specific requirements and improve the consistency of product quality. The movable plate 14 slides in the sliding groove 16, and the moving block 15 slides on the outer wall of the machine body 1, providing a stable guide for the movement of the fixed jaw plate 13, ensuring the stable operation of the equipment when adjusting the size of the discharge port and reducing the occurrence of faults. Therefore, according to the characteristics of different materials and the crushing requirements, the vibration frequency and the size of the discharge port can be flexibly adjusted, so that the crusher can adapt to a variety of working conditions and material types.

[0041] Refer to the attached Figure 5 , the adjusting mechanism 2 includes a plurality of fixing columns 201, the outer walls of the plurality of fixing columns 201 are fixedly connected to the four corners of the outer wall of the machine body 1, telescopic members 202 are fixedly connected to the inner sides of the plurality of fixing columns 201, support legs 208 are fixedly connected to the bottoms of the plurality of telescopic members 202, connecting frames 203 are arranged on the outer walls of the plurality of fixing columns 201, through holes 204 are opened on the outer walls of the plurality of fixing columns 201 and the connecting frames 203, the plurality of through holes 204 are connected by bolts 205, a rotating shaft III 206 is fixedly connected to the inner side of the bottom of the connecting frame 203, and a wheel 207 is fixedly connected to the outer wall of the rotating shaft III 206; the inner diameter sizes of the plurality of through holes 204 are adapted to the diameter sizes of the bolts 205;

[0042] Specifically, the telescopic member 202 can conveniently change the position and height of the crusher to adapt to different working sites and technological process requirements, improving the versatility and applicability of the equipment. When the crusher needs to be moved, loosen the bolt 205 and lower the connecting frame 203 so that the wheel 207 touches the ground, and the crusher can be easily pushed, greatly saving manpower and time and improving the mobility of the equipment. In the working state, the bolt 205 fixes the connecting frame 203, and the telescopic member 202 and the support leg 208 provide stable support, effectively reducing the shaking and vibration during equipment operation and ensuring the stability and accuracy of the crushing work.

[0043] Refer to the appendix Figure 1 , a stabilizing wheel 10 is fixedly connected to the rear side of the rotating shaft three 206, and the outer wall of the stabilizing wheel 10 is fixedly connected to the rear side of the machine body 1; a fixing frame 17 is fixedly connected to the bottom of the servo motor one 3, and the outer wall of the fixing frame 17 is fixedly connected to the left side of the machine body 1; baffles 18 are fixedly connected to the front and rear sides of the movable jaw plate 9, and the far sides of the two baffles 18 are fixedly connected to the inside of the machine body 1;

[0044] Specifically, during crushing, the stabilizing wheel 10 can provide additional support and balance. The fixing frame 17 can provide a stable installation and support for the servo motor one 3, reducing the vibration and displacement of the motor during operation and ensuring the stability and accuracy of its output. The baffle 18 can effectively block the material from splashing out of the movable jaw plate 9 during the crushing process, ensuring the safety and cleanliness of the working environment and at the same time restricting the movement range of the material in the crushing cavity, which helps to improve the crushing effect and efficiency.

[0045] Working principle: When the jaw crusher starts working, start the servo motor 1-3, the output end of which drives the rotating shaft 1-4 to rotate. The pulley 1-5 on the rotating shaft 1-4 drives the pulley 2-7 on the rotating shaft 2-6 through the belt 8, so that the movable jaw plate 9 vibrates, which helps to break and discharge the materials. When it is necessary to adjust the size of the discharge opening, start the servo motor 2-11, the servo motor 2-11 drives the rotating rod 12 to rotate, the rotating rod 12 drives the fixed jaw plate 13 to rotate, and both ends of the movable plate 14 at the top of the fixed jaw plate 13 slide in the chute 16, and the moving blocks 15 at both ends of the movable plate 14 also slide on the outer wall of the machine body 1, so as to change the position of the fixed jaw plate 13. The gap between the fixed jaw plate 13 and the movable jaw plate 9 forms the discharge opening. By adjusting the rotation of the fixed jaw plate 13 by the servo motor 2-11, the relative position between the two is changed, and thus the size of the discharge opening is adjusted; and when it is necessary to adjust the position or height of the jaw crusher, the height of the support leg 208 is changed by controlling the telescopic movement of the telescopic member 202. When it is necessary to move the crusher, take out the bolt 205 from the through hole 204, so that the connecting frame 203 can move downward along the fixed column 201. When the connecting frame 203 moves to a suitable position, the wheel 207 touches the ground and the support leg 208 is suspended. At this time, the crusher can be conveniently pushed to move by using the wheel 207.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
