[0018] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not used to limit the present utility model.

[0019] Among them, the same reference numerals in the drawings all refer to the same components. Embodiment

[0020] As Figure 1 , Figure 2 shown, the present utility model provides an adjusting device for a compound pendulum crusher, including a compound pendulum adjusting jaw crusher and a compound pendulum adjusting end. The compound pendulum adjusting jaw crusher includes a moving jaw body and an elbow plate support. The compound pendulum adjusting end includes a tie rod 1, a bracket 2, an adjusting spring 3, a spring guiding end 4, a protection plate 5, a tensioning oil cylinder 6, a bolt 7, a washer 8 and a nut 9.

[0021] The front end of the tie rod 1 is provided with a mounting hole, and the rear end is provided with a threaded high-strength steel piece. The bottom end of the tie rod 1 is connected to the moving jaw body, and the top end passes through the hole of the bracket 2 and is fixedly connected.

[0022] The bracket 2 is arranged in a "7" shape. One side surface is provided with a screw hole, and the other side surface is provided with a positioning hole. The bracket 2 is used for installing and fixing the tensioning oil cylinder 6 and the adjusting spring 3.

[0023] The front end of the tie rod 1 is connected to the moving jaw body, and the rear end sequentially passes through the positioning hole of the bracket 2, the adjusting spring 3, the spring guiding end 4 and the tensioning oil cylinder 6. The tensioning oil cylinder 6 and the spring guiding end 4 are installed in series with the adjusting spring 3 through the central hole of the tie rod 1 passing through them.

[0024] The adjusting spring 3 is arranged as a cylindrical compression helical spring. The spring guiding end 4 is composed of a T-shaped high-strength steel piece. The tensioning oil cylinder 6 is arranged as a hydraulic cylinder with a self-locking function.

[0025] Specifically, its structure consists of a pull rod 1, a bracket 2, an adjusting spring 3, a spring guiding end 4, a protection plate 5, a tensioning oil cylinder 6, bolts 7, washers 8 and nuts 9 to form an adjusting device for a compound pendulum crusher. Through this adjusting device for a compound pendulum crusher, the technical problems of high wear of the oil cylinder during the working process of the compound pendulum adjusting device, high maintenance cost, and time-consuming and laborious adjustment of the discharge opening of the jaw crusher, which are not conducive to industrial production, can be effectively solved. The pull rod 1 is connected to the moving jaw body of the compound pendulum adjusting jaw crusher to pull the moving jaw back, which is used for the connection between the compound pendulum adjusting device and the workpiece. The bracket 2 is used to support the pull rod 1. The spring guiding end 4 as a whole plays a role in positioning the adjusting spring 3 for guiding the expansion and contraction of the adjusting spring 3. The protection plate 5 plays an insurance role when the pressure of the compound pendulum adjusting device gets out of control. When adjusting the discharge opening of the jaw crusher, it can pressurize to make the pull rod 1 press against the adjusting spring 3, so that the self-locking locking disc is not squeezed by the spring, which is convenient to loosen the locking disc. After the pressure is released, the pull rod will not generate a pulling force on the connected moving jaw body. Only when the pull rod 1 does not generate a pulling force on the moving jaw body can the discharge port be adjusted. After being spliced by bolts 7, washers 8 and nuts 9, they are used to fix the bracket 2 to the toggle plate support, so that the adjusting device for a compound pendulum crusher can effectively improve the service life of the oil cylinder and is more convenient when adjusting the discharge port.

[0026] Furthermore, when in use, the cylinder body of the tensioning oil cylinder 6 is hollow. The pull rod 1 passes through the middle hole of the tensioning oil cylinder 6 and is connected to the oil cylinder. The pull rod 1 passes through the central positioning holes of the adjusting spring 3 and the spring guiding end 4. The adjusting spring 3, the spring guiding end 4 and the tensioning oil cylinder 6 are connected in series. The front end of the adjusting spring 3 is limited by the bracket 2, and the tail of the tensioning oil cylinder 6 is limited by the nut 9. When the adjusting device works and the moving jaw swings forward, it drives the cylinder body of the tensioning oil cylinder 6 on the pull rod 1 to squeeze the adjusting spring 3. The reaction force generated by the squeezing of the adjusting spring 3 pulls the moving jaw backward. When adjusting the discharge opening of the jaw crusher, the oil cylinder can be pressurized to make the piston rod press against the spring guiding end 4, and then manually loosen the self-locking device on the adjusting tensioning oil cylinder 6. After the tensioning oil cylinder 6 is depressurized, the discharge port can be adjusted, which is time-saving and labor-saving and can effectively improve the overall practical performance.

[0027] To sum up, the utility model has two ways of mechanical locking and hydraulic locking when locking the moving jaw, which is time-saving and labor-saving when adjusting the discharge port; and it can reduce the friction between the piston rod of the oil cylinder and the seal during work, improve the service life of the oil cylinder, reduce the expenditure of maintenance costs, and effectively improve the overall working efficiency.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model 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 modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
