DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] During specific implementation: As Figures 1-4As shown in the figure, the belt pulley protection device of a spring cone crusher includes: a working frame 1, a protection frame 2 is fixedly connected to the front end of the working frame 1, both sides of the inner wall of the protection frame 2 are rotatably connected with a first pulley 3, a second pulley 5 is arranged on the inner wall of the protection frame 2, and a belt 4 is drivingly connected between the first pulley 3 and the second pulley 5; an adjustment mechanism 6, wherein the adjustment mechanism 6 is arranged on the surface of the protection frame 2; among them, the adjustment mechanism 6 includes a protection cylinder 61 fixedly connected to the bottom of the protection frame 2, a lead screw 63 is rotatably connected to the inner wall of the protection cylinder 61, a protection rod 62 is threadedly connected to the surface of the lead screw 63, the top end of the protection rod 62 penetrates through the protection frame 2 and is fixedly connected with a sliding seat 64, the surface of the second pulley 5 is rotatably connected to the inside of the sliding seat 64, the bottom end of the lead screw 63 is fixedly connected with a dial 65, a limiting ring 66 is fixedly connected to the surface of the protection cylinder 61, a limiting block 67 is slidably connected to the upper end surface of the dial 65, one side of the limiting block 67 is clamped inside the limiting ring 66, magnetic rings 68 are fixedly connected to the surface of the limiting block 67 and one end of the dial 65, the two magnetic rings 68 attract each other with opposite poles, and a fixed rod 614 is fixedly connected to the inner wall of the protection cylinder 61, and the inner wall of the protection rod 62 is slidably connected to the surface of the fixed rod 614.

[0025] The surface of the limiting ring 66 is provided with annularly distributed concave holes, one side of the limiting block 67 is clamped inside one of the concave holes, a servo motor and a spring cone crusher are fixedly connected to the top of the working frame 1, the output shaft of the servo motor is fixedly connected to one end of one of the first pulleys 3, and the other end of the other first pulley 3 is fixedly connected to one end of the spring cone crusher. The crushing process of the spring cone crusher for materials is an existing conventional technology, so it will not be elaborated here.

[0026] When it is necessary to tension and protect the first pulley 3 and the belt 4, rotate the dial 65. The rotation of the dial 65 drives the lead screw 63. The rotation of the lead screw 63 drives the protection rod 62 and the sliding seat 64 to move downward. The downward movement of the sliding seat 64 drives the second pulley 5 to move downward, so that the belt 4 and the first pulley 3 reach a suitable tension state. Push the limiting block 67 to make the limiting block 67 clamped inside the limiting ring 66, and one of the magnetic rings 68 is adsorbed on the other magnetic ring 68 to position the dial 65.

[0027] As Figures 2-3 shown, a transparent window 612 is hinged to the front end of the protection frame 2. The upper end surface of the transparent window 612 is clamped to the inner wall of the protection frame 2. A sealing ring 613 is fixedly connected to the rear end of the transparent window 612. An installation block 69 is slidably connected to the inner wall of the protection frame 2. The surface of the installation block 69 is clamped to the inner wall of the transparent window 612. A telescopic spring 610 is fixedly connected to the opposite sides of the installation block 69 and the protection frame 2. A sliding rod 611 is fixedly connected to the inner wall of the installation block 69. The surface of the sliding rod 611 is slidably connected to the inner wall of the protection frame 2. A handle is fixedly connected to the front end of the transparent window 612.

[0028] When the first pulley 3, the belt 4 and the second pulley 5 need to be repaired, pull the slide bar 611. The movement of the slide bar 611 drives the two mounting blocks 69 to move away from the inside of the transparent window 612 at the same time. Pull the handle to flip the transparent window 612, so that the front end of the protective frame 2 is opened, and the first pulley 3, the belt 4 and the second pulley 5 can be repaired.

[0029] When the present utility model is in use, the tension state of the first pulley 3 and the belt 4 is observed through the transparent window 612. When the belt 4 is loose on the first pulley 3, rotate the dial 65. The rotation of the dial 65 drives the lead screw 63. The rotation of the lead screw 63 drives the protective rod 62 and the slide seat 64 to move downward. The downward movement of the slide seat 64 drives the second pulley 5 to move downward, so that the belt 4 and the first pulley 3 reach a suitable tension state. Push the limit block 67 to make the limit block 67 snap into the inner side of the limit ring 66, and one magnetic ring 68 is adsorbed on the other magnetic ring 68 to position the dial 65.

[0030] It should be noted that in the above description, the spring cone crusher, the servo motor, the magnetic ring 68, the sealing ring 613, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the spring cone crusher and the servo motor can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
