Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 3 As shown, a jaw crusher inclined wedge adjustment device includes a device body, which includes a rotating seat 2, an adjusting screw, and a lever 4 for rotating the adjusting screw. The rotating seat 2 is sleeved on the adjusting screw. The adjusting screw includes a first screw part 31 and a second screw part 32, which are connected to each other. The lever 4 is bolted to the second screw part 32.

[0020] The second screw part 32 has a first threaded hole 321 on its side wall;

[0021] The top of the rotating seat 2 is provided with a second threaded hole 21, and an anti-rotation pin 22 is internally threaded into the second threaded hole 21 of the rotating seat 2. One end of the anti-rotation pin 22 passes through the second threaded hole 21 of the rotating seat 2 and is internally threaded into the first threaded hole 321 of the second screw part 32 and abuts against it to prevent rotation.

[0022] The rotating seat 2 is also symmetrically equipped with thrust bearings 5 ​​for balancing axial forces.

[0023] In this utility model, the thrust bearing 5 is existing technology.

[0024] With the above structure, the anti-rotation pin 22 is threaded into the second threaded hole 21 on the rotating seat 2 and threaded into the second threaded hole 21 on the rotating seat 2. The second threaded hole 21 leads to the second screw part 32. When adjustment is required, the anti-rotation pin 22 is not screwed into the second threaded hole 21. The operator adjusts the adjusting screw by rotating the lever 4. After adjustment, the anti-rotation pin 22 is screwed into the second threaded hole 21 of the rotating seat 2 and screwed until one end of the anti-rotation pin 22 abuts against the surface of the second screw part 32 at the bottom of the second threaded hole 21. This facilitates anti-rotation and is simple in structure and low in cost. The operator only needs to rotate one end of the anti-rotation pin 22 to abut against the surface of the second screw part 32, making anti-rotation operation more convenient.

[0025] Specifically, such as Figures 1 to 3 As shown, round nuts 6 are sequentially installed on the side of the rotating seat 2 near the lever 4, and the round nuts 6 are connected to one side of the rotating seat 2.

[0026] In this utility model, the round nut 6 is existing technology.

[0027] With the above structure, by setting a round nut 6, which is used in conjunction with the thrust bearing 5 through a washer, the round nut 6 can be inserted into the side wall of the rotating seat 2 near the lever 4, which is beneficial to provide a larger axial force and makes disassembly and assembly more convenient.

[0028] like Figures 1 to 3 As shown, a mounting cover 7 is installed on the side of the rotating base 2 away from the lever 4. The mounting cover 7 facilitates disassembly and assembly and provides a certain degree of protection.

[0029] like Figures 1 to 3 As shown, a dust cover 8 is fitted onto the first screw section 31. By setting the dust cover 8, it is beneficial to further protect the adjusting screw from dust, prevent the first screw section 31 from direct contact with the outside world, prevent dust from falling onto the surface of the first screw section 31, and achieve a better dust protection effect.

[0030] like Figures 1 to 3 As shown, an adjusting sleeve 9 is fitted onto the second screw section 32. The adjusting sleeve 9 facilitates adjustment.

[0031] like Figures 1 to 3 As shown, the first screw portion 31 and the second screw portion 32 are located on the same axis.
