[0019] Please refer to Figures 1-5 , the present invention provides a technical solution: a quick adjustment device for the discharge port of a jaw crusher, including a crusher main body 1, a moving jaw 2 and an adjustable stationary jaw 3 respectively arranged on the crusher main body 1. By quickly adjusting the adjustable stationary jaw 3, the quick adjustment of the discharge port of the jaw crusher is realized, with simple operation and simplified process, greatly improving the work efficiency and accelerating the project progress.

[0020] Specifically, two groups of a total of four sliding grooves 5 are symmetrically opened on the inner side surfaces of both sides of the crusher main body 1. Sliders 6 are slidably arranged in the sliding grooves 5. The sliders 6 are fixedly connected to the stationary jaw 3. The stationary jaw 3 moves along the length direction of the sliding groove 5 through the sliders 6 to adjust the distance between it and the moving jaw 2, thereby adjusting the size of the discharge port.

[0021] A screw rod 4 is rotatably arranged in a sliding groove 5. The screw rod 4 is in threaded connection with a threaded hole formed in the side surface of a slider 6. The rotation of the screw rod 4 drives the slider 6 and a stationary jaw 3 to move. The end of the screw rod 4 penetrates through the outer surface of a crusher main body 1 and is connected to a sprocket I 8. A transmission chain I 9 is arranged between two sprockets I 8 located on the same vertical line. Sprockets II 11 are further arranged at the ends of the two screw rods 4 located at the lower side. A transmission chain II 12 is arranged between the two sprockets II 11. A rotating handle 14 is rotatably arranged on the side surface of one of the sprockets II 11. By operating the rotating handle 14, the sprocket II 11 connected thereto is driven to rotate. The sprocket II 11 drives the other sprocket II 11 to rotate through the transmission chain II 12. While the two sprockets II 11 rotate synchronously, the screw rods 4 connected thereto drive their respective sprockets I 8 to rotate. The two sprockets I 8 located at the lower side drive the two sprockets I 8 located at the upper side to rotate synchronously through the transmission chain I 9. Thus, the synchronous rotation of the four screw rods 4 is realized. The four screw rods 4 drive the slider 6 to move in the sliding groove 5, thereby driving the stationary jaw 3 to move back and forth. The size of a discharge port is adjusted according to equipment wear and the requirements of the finished product particle size of materials, so as to realize the rapid adjustment of the discharge port without the need for shutdown operation, and the working efficiency is significantly improved.

[0022] The rotating handle 14 can also be replaced with a common servo motor or a reduction motor, etc. The servo motor drives the sprocket II 11, the sprocket I 8, the screw rod 4, etc. to rotate, and further saves labor and improves the working efficiency through electric control.

[0023] In a preferred technical solution, baffles I 10 are arranged on the outer surfaces of the two sprockets I 8 located at the upper side for limiting and protecting the transmission chain I 9 to prevent the transmission chain I 9 from disengaging; baffles II 13 are arranged on the outer surfaces of the sprockets II 11 for limiting and protecting the transmission chain II 12 to prevent the transmission chain II 12 from disengaging.

[0024] Furthermore, the rotating handle 14 penetrates through the side surface of the baffle II 13. The rotating handle 14 can also be rotatably arranged on the outer surface of the baffle II 13. A rubber sponge pad can be arranged on the outer side of the rotating handle 14, which is more convenient and comfortable to operate.

[0025] The preferred technical solution is that the side surfaces of the baffle I10, baffle II13, sprocket I8 and sprocket II11 are each provided with a through hole, and a positioning pin 15 is installed in the through hole. The outer surface of the crusher body 1 is evenly provided with a plurality of positioning holes at the corresponding position of the sprocket I8. The positioning holes are evenly arranged in a circular array on the outside of the axis of the corresponding screw 4. The positioning pin 15 passes through the through hole and is inserted into the corresponding positioning hole. The positioning pin 15 can fix each baffle and sprocket, etc., so that they will not rotate, and the screw 4 is prevented from rotating and affecting the operation of the crusher body 1. The positioning pin 15 can be made of high-strength material, or a U-shaped positioning pin can be selected, and two through holes are provided. The two sections of the U-shaped positioning pin 15 are respectively inserted into the two through holes to further improve the firmness and stability of its positioning.

[0026] Further preferably, the number of the positioning holes is not less than 10, so that the discharge port can be adjusted in multiple stages to suit different crushing requirements.

[0027] A preferred technical solution is that a telescopic plate 7 is arranged between the slider 6 and the side surface of the chute 5. The telescopic plate 7 is made of high-toughness engineering plastic or alloy, and a plurality of folds are arranged on its side surface. When the slider 6 moves in the chute 5, the telescopic plate 7 can be compressed or stretched so that it can always cover the chute 5, thereby preventing gravel and the like falling into the crusher body 1 from entering the chute 5 and affecting the rotation of the screw 4 and the slider 6.

[0028] A preferred technical solution, in which a rotating plate 16 is installed at the end of one of the screws 4 located at the lower side, and the rotating plate 16 is arranged between the sprocket wheel I8 and the sprocket wheel II11.

The outer surface of the crusher body 1 is evenly provided with a number of scale lines 19 corresponding to the pointer 18, and the scale lines 19 are marked with numbers 1-N, N is a natural number greater than or equal to 10. When adjusting the size of the discharge port, the sprocket wheel I8, the sprocket wheel II11 and the screw 4 rotate one circle, and the rotating plate 16 also rotates one circle. The fixed teeth at its end turn the counting gear 17 to rotate the corresponding angle, and the pointer 18 on the counting gear 17 rotates and points to the corresponding scale line 19 and number. During the adjustment process, the staff can grasp the number of adjustment circles and control the position of the static jaw 3 according to the number indicated by the pointer 18, and the adjustment is more convenient and accurate.

[0029] Optionally, it further includes a wedge block 20. The lower part of the wedge block 20 is a right triangle. The movable jaw 3 is adjusted to be in close contact with the inner surface of the side plate of the crusher main body 1. At this time, the discharge port of the crusher main body 1 is the largest. When it is necessary to adjust the discharge port of the crusher main body 1 to be smaller, the movable jaw 3 moves inward under the drive of each screw 4 to adjust the discharge port to the corresponding size. Then, each sprocket is fixed, and then the wedge block 20 is inserted between the movable jaw 3 and the side plate of the crusher main body 1 to play a role in supporting and stabilizing the movable jaw, making the crusher main body 1 more stable when crushing raw materials. At the same time, it can also protect components such as the screw 4 and the sprocket, and extend the service life of the equipment.

[0030] Further optionally, at least one hanging ring 21 is provided on the upper surface of the wedge block 20.
