[0029] The isolation assembly 4 includes a base 41, a rod 42 fixedly connected to the top surface of the base 41, an isolation cover 43 provided on the top surface of the base 41, a rubber curtain 44 provided on one side of the isolation cover 43 at the opening corresponding to the discharge port 5, a hinge seat 48 fixedly connected to the top of the isolation cover 43, a cover plate 49 hinged to one side of the hinge seat 48, a back plate 45 provided on one side of the isolation cover 43, a bolt 46 slidably connected to the back plate 45 through a through hole therein, and the bolt 46 threadedly connected to the isolation cover 43 through a threaded hole therein.
[0030] The top surface of the base 41 has a groove with the same shape as the bottom of the crusher 1. The bottom of the isolation cover 43 has a groove corresponding to the insertion rod 42 and a protruding ring is provided in the groove. The isolation cover 43 and the back plate 45 both have insertion holes 47 on one side. The isolation cover 43 is provided with sealing gaskets at the positions where it contacts the cover plate 49 and the back plate 45.
[0031] The specific implementation method is as follows: During installation, the crusher 1 is placed in the groove on the top surface of the base 41. At the same time, the sound insulation cotton 31 is fixed to the inner wall of the isolation cover 43 by the fixing component 3. The isolation cover 43 is placed on the base 41 and the insertion rod 42 is inserted into the groove opened at the bottom of the isolation cover 43. The protruding ring in the groove is used to make it engage with the groove on the outer wall of the insertion rod 42 for fixing. At the same time, the back plate 45 is fixed to the isolation cover 43 by the bolt 46, so that the crusher 1 is located inside the isolation cover 43.
[0032] The fixing component 3 includes a fixing frame 32. A sound-insulating cotton 31 is provided on one side of the fixing frame 32. A plug 33 is fixedly connected to the fixing frame 32 through a through hole. A sliding rod 37 is slidably connected to the plug 33 through a groove. The plug 33 is slidably connected to the sound-insulating cotton 31 through a through hole. Connecting rods 39 are fixedly connected to both sides of the sliding rod 37. A connecting block 35 is fixedly connected to one end of the sliding rod 37. A rotating plate 36 is rotatably connected to the outer wall of the connecting block 35. The plug... One end of the insert 33 is fixedly connected to a limiting frame 34. The insert 33 is slidably connected to a slider 38 through a groove on its outer wall. One end of the slider 37 is fixedly connected to a spring 310. The round rod at one end of the connecting rod 39 is slidably connected to the slider 38 through a groove in the slider 38. The insert 33 is slidably connected to the insertion hole 47. A groove is provided on the inner wall of the insertion hole 47, and the slider 38 is slidably connected to the groove. The limiting frame 34 has an opening, and the fixed plate on the outer wall of the rotating plate 36 is slidably connected to the opening.
[0033] The specific implementation method is as follows: When replacing the sound insulation cotton 31, the rotating bolt 46 is used to remove it, thereby separating the back plate 45 from the isolation cover 43. The isolation cover 43 is then lifted upwards to separate it from the insertion rod 42. Then, the rotating plate 36 is rotated to make it slide out from the opening on one side of the limiting frame 34. The spring 310 pushes the sliding rod 37 and drives the connecting rod 39 to move, so that the cylinder at one end of the connecting rod 39 slides in the groove in the slider 38, thereby driving the slider 38 to move and retract into the insertion tube 33. The slider 38 is then removed from the groove opened in the inner wall of the insertion hole 47. The fixing frame 32 and the sound insulation cotton 31 can be removed by pulling the insertion tube 33 outwards to separate it from the insertion hole 47.
[0034] Working principle: During installation, the crusher 1 is placed in the groove on the top surface of the base 41. Simultaneously, the sound insulation cotton 31 is placed on the inner wall of the isolation cover 43, and the insert cylinder 33 is inserted through the sound insulation cotton 31 into the insertion hole 47. The rotating plate 36 is pushed, causing the sliding rod 37 to move inward and the connecting rod 39 to move, while simultaneously compressing the spring 310. This causes the cylinder at one end of the connecting rod 39 to slide in the groove within the slider 38, thus moving the slider 38 into the groove on the inner wall of the insertion hole 47. Then, the rotating plate 36 is rotated, causing its outer wall fixing plate to slide through the opening of the limiting frame 34 into the limiting frame 34. The reaction force of the spring 310 causes the fixing plate on the outer wall of the rotating plate 36 to make tight contact with the limiting frame 34. The fixing frame 32 then fixes the sound insulation cotton 31 to the inner wall of the isolation cover 43. The isolation cover 43 is then placed above the base 41, and the insert cylinder 42 is inserted into the opening at the bottom of the isolation cover 43. The groove is fixed by engaging the protruding ring inside the groove with the groove on the outer wall of the insert rod 42. At the same time, the back plate 45 is fixed to the isolation cover 43 by the bolt 46, so that the crusher 1 is located inside the isolation cover 43. When replacing the sound insulation cotton 31, the bolt 46 is rotated to remove it, thereby separating the back plate 45 from the isolation cover 43. The isolation cover 43 is then lifted upward to separate it from the insert rod 42. Then, the rotating plate 36 is rotated to slide out from the opening on one side of the limit frame 34. The spring 310 pushes the slide rod 37 and drives the connecting rod 39 to move, so that the cylinder at one end of the connecting rod 39 slides in the groove in the slider 38, thereby driving the slider 38 to move and retract into the insert 33. The slider 38 is then removed from the groove opened in the inner wall of the insertion hole 47. The fixing frame 32 and the sound insulation cotton 31 can be removed by pulling the insert 33 outward to separate it from the insertion hole 47.
