[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-5 The utility model provides a technical solution: a new type of jaw crusher fixed bottom plate and two side wall panel installation structure, including a wall panel body 1, a bottom plate body 2, a dovetail groove 3, an inclined wedge 4, a convex surface 5, a boss 6, a keyway hole 7, a flat key 8, an opening 9, a threaded hole 10, a double-headed screw 11, and a nut 12.

[0030] Example 1: The fixed bottom plate of the new jaw crusher and the wall panel mounting structures on both sides are provided with a docking structure, so that the connection area between the wall panel body 1 and the bottom plate body 2 is increased, specifically:

[0031] The wall panel body 1 is symmetrically provided with two, and also includes a bottom plate body 2, and bosses 6 are provided at both ends of the bottom plate body 2. The front surface of the wall panel body 1 is provided with a docking structure, and the docking structure can be engaged with the boss 6 through a dovetail groove 3 to form a docking. The docking structure includes a dovetail groove 3, which is opened on the front surface of the bottom plate body 2, and a side surface of the dovetail groove 3 is provided with an oblique wedge 4. The front surface of the bottom plate body 2 is provided with a convex surface 5, and the front surface of the convex surface 5 is provided with an opening 9, and the openings 9 are provided with 5 equal intervals. The bosses 6 provided at both ends of the bottom plate body 2 match the shape of the dovetail groove 3, and the bottom plate body 2 is provided with a through opening corresponding to the position of the opening 9;

[0032] When the new jaw crusher fixed bottom plate and the two side wall panel installation structure are in use, first, since the bosses 6 installed at both ends of the plate body 2 correspond to the shape of the dovetail groove 3, the bosses 6 installed at both ends of the bottom plate body 2 are respectively inserted between the dovetail grooves 3 on the front surface of the corresponding wall panel body 1, and one side of the dovetail groove 3 is set to a bevel 4, so that the connection area between the dovetail grooves 3 is larger and can withstand greater forces, thereby enhancing the stability of the entire structure. When the jaw crusher is working, it needs to withstand huge pressure and friction from the material, and this design of increasing the connection area can effectively disperse these loads, avoid local stress concentration, and improve the carrying capacity of the equipment. The correspondence between the dovetail groove 3 and the boss 6 makes the installation guided, which makes it easier to align and connect the components during the installation process. After the bottom plate body 2 and the dovetail groove 3 are docked, the opening 9 set through the front surface of the convex surface 5 will correspond to the through opening set on the bottom plate body 2, which is convenient for the subsequent installation of the locking structure.

[0033] Example 2: The new jaw crusher fixed bottom plate and the two side wall plate installation structure are also provided with a locking structure, through the flat key 8 and the double-headed screw 11 to make the installation more stable, specifically:

[0034] The bottom plate body 2 is also connected to a locking structure, which connects the wall panel body 1 and the bottom plate body 2. The locking structure includes a key slot hole 7. The front surface of the convex surface 5 is provided with a key slot hole 7, and the other end of the key slot hole 7 extends to the front surface of the dovetail groove 3. The two end surfaces of the bottom plate body 2 are provided with key slot holes 7 corresponding to the key slot holes 7 opened on the front surface of the convex surface 5. The front surface of the dovetail groove 3 is provided with a plurality of threaded holes 10. A stud screw 11 is installed through the opening 9. Nuts 12 are connected to both ends of the stud screw 11. A flat key 8 is inserted between the key slot holes 7.

[0035] Furthermore, the double-headed screw 11 is made to pass through the opening 9 and the opening of the bottom plate body 2 set on the front surface of the convex surface 5, and then the nuts 12 connected at both ends of the double-headed screw 11 are tightened to make the fixation more firm. As the equipment is used, the components may wear and deform. The tension can be adjusted through the nuts 12 at both ends of the double-headed screw 11 to compensate for the wear changes in time. There are 5 double-headed screws 11 corresponding to the openings 9, which makes the bearing capacity stronger and the force between the bottom plate body 2 and the wall panel bodies 1 on both sides more uniform. When the crusher is working, it can effectively disperse the impact force from the material and the equipment. The equipment has its own vibration, and the key slot holes 7 opened on the wall panel body 1 and the bottom plate body 2 correspond to each other, so that the flat key 8 is inserted into the key slot hole 7. The flat key 8 can share the shear force borne by the double-headed screw 11, thereby reducing the stress concentration degree of the double-headed screw 11 and improving the stability of the entire installation structure. During the operation of the crusher, it can better withstand the impact force and vibration from the crushed materials and reduce the risk of structural damage caused by stress concentration. A plurality of threaded holes 10 are provided on the front surface of the dovetail groove 3, and bolts are passed through the threaded holes 10 so that the wall panel body 1 and the bottom plate body 2 can be connected more tightly.

[0036] Working principle: When using the new jaw crusher to fix the bottom plate and the wall panels on both sides, a docking structure is provided. The dovetail groove 3 increases the connection area between the wall panel body 1 and the bottom plate body 2. A locking structure is also provided. The flat key 8 and the double-headed screw 11 can make the installation more stable and increase the overall practicality.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
