[0025] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0026] See also Figures 1-4 As shown, the purpose of this embodiment is to provide a safety locking device for a toothed roller crusher, comprising a shell 1, a crushing chamber is provided in the shell 1, a crushing roller 2 is rotatably installed in the crushing chamber, both ends of the crushing roller 2 are fixedly connected to a rotating shaft 21, one end of the rotating shaft 21 is fixedly provided with a safety locking device 3, the safety locking device 3 comprises a fixed block 22, the fixed block 22 is slidably mounted on the side wall of the shell 1, and the rotating shaft 21 is rotatably mounted in the fixed block 22, one end of the fixed block 22 is provided with a pull rod 36 for adjusting the gap between the crushing roller 2, and one end of the fixed block 22 is provided with a screw 37 for limiting.

[0027] The safety locking device 3 includes a lower plate 31, which is fixedly mounted on the side wall of the shell 1. The side wall of the shell 1 is also fixedly mounted with an upper plate 32. One end of the fixed block 22 is slidably mounted in the lower plate 31, and the other end of the fixed block 22 is slidably mounted in the upper plate 32. Both the upper plate 32 and the lower plate 31 are provided with through grooves. Sliders are fixedly provided at both ends of the fixed block 22. The slides are slidably mounted in the through grooves, and the length of the through grooves is greater than the length of the slide.

[0028] A first fixed plate 33 is fixedly provided between the lower plate 31 and the upper plate 32 . A sliding plate 34 is slidably provided between the lower plate 31 and the upper plate 32 . One end of the pull rod 36 passes through and extends out of the first fixed plate 33 and the sliding plate 34 .

[0029] A groove 221 is provided on one side of the fixed block 22, a column groove 341 is provided in the sliding plate 34, a first limit block 361 is fixedly provided at one end of the pull rod 36, and a second limit block 363 is fixedly provided at the center of the pull rod 36. A groove 221 is provided on the side wall of the fixed block 22, the first limit block 361 is slidably installed in the groove 221, and the second limit block 363 is fixedly installed in the column groove 341.

[0030] One end of the groove 221 is an annular groove 222, the diameter of the annular groove 222 is the same as that of the first limit block 361, and the thickness of the annular groove 222 is greater than the thickness of the first limit block 361, and the movable distance of the first limit block 361 in the groove 221 is the thickness difference between the thickness of the annular groove 222 and the thickness of the first limit block 361. The groove 221 plays a limiting role on the pull rod 36, and the column groove 341 is used to connect the pull rod 36 and the sliding plate 34, so that the sliding plate 34 moves in the horizontal movement direction of the pull rod 36.

[0031] Two screw rods 37 are fixedly provided on one side of the first fixing plate 33 , and the screw rods 37 pass through and are slidably installed in the sliding plate 34 .

[0032] A nut 39 is threadedly mounted on one end of the screw rod 37 , and the position of the screw rod 37 is fixed by tightening the nut 39 .

[0033] A plurality of screw holes 322 are provided at one end of the upper plate 32, and two column holes are provided on the top of the sliding plate 34. Screws 321 are installed in the inner threads of the column holes. The screws 321 pass through the screw holes 322 and are installed on the upper plate 32 with threads. When the crushing roller 2 is adjusted, the distance the crushing roller 2 is adjusted each time is the same as the distance between the two screw holes 322. Locking at multiple locations can effectively prevent the crushing roller 2 from loosening and causing safety problems.

[0034] A number of disc springs 362 are stacked on the pull rod 36, one end of the disc spring 362 is fixedly connected to the side wall of the fixed block 22, and the other end of the disc spring 362 is fixedly connected to the side wall of the first fixed plate 33. The stacked disc springs 362 can withstand greater pressure, so that when the fixed block 22 is fine-tuned after being fixed, it can buffer the vibration of the crushing roller 2 and maintain stable performance when bearing heavy loads. The disc springs 362 can absorb and disperse the energy brought by the vibration, reducing the impact on the equipment.

[0035] A spring 372 is provided on the screw 37, one end of the spring 372 is fixedly connected to the side wall of the first fixed plate 33, and the other end of the spring 372 is fixedly connected to the side wall of the sliding plate 34. The installation of the spring 372 plays a buffering role, which can protect the screw 37 from excessive stress and extend its service life.

[0036] When the present invention is used in practice, according to the appropriate crushing accuracy, the pull rod 36 is pulled, the fixed block 22 slides with the pull rod 36, and the sliding plate 34 slides with the pull rod 36. After the adjustment is completed, the nut 39 on the screw 37 is tightened so that one end of the nut 39 is close to the sliding plate 34, and then the screw 321 is threadedly installed in the screw hole 322 and the column hole to fix the position of the sliding plate 34. Since the first limit block 361 is slidably installed in the annular groove 222, the fixed block 22 can be slightly adjusted in position after being fixed. During this process, the disc spring 362 plays a buffering role when the fixed block 22 is fine-tuned.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
