The extrusion plate restricted by the limit vertical slot will move downward under the drive of the lead screw. The extrusion plate drives the support column to overcome the pulling force of spring 3 and slide downward along the limit inclined slot.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, in the present embodiment, a noise reduction base for a cone crusher comprises a mounting frame 1, characterized in that: a same placement plate 2 is slidably connected inside the mounting frame 1, a plurality of shock absorbing components 5 distributed at equal distances are installed between the mounting frame 1 and the placement plate 2, the shock absorbing component 5 comprises a same limiting rod 501 fixedly connected to the bottom of the inner walls on both sides of the mounting frame 1, the external sliding sleeve of the limiting rod 501 is provided with two symmetrically arranged mounting blocks 502, the tops of the two mounting blocks 502 are both rotatably connected with a connecting strip 503, the two connecting strips 503 are both rotatably connected to the bottom of the placement plate 2, the limiting rod 501 sleeve is provided with a second spring 504, the second spring 504 is located in the middle position of the two mounting blocks 502, a damper 505 is fixedly installed on the inner walls on both sides of the mounting frame 1, and the movable ends of the two dampers 505 are respectively fixedly connected to the outside of the two mounting blocks 502.

[0024] As the crusher body vibrates during operation, the placement plate 2 moves synchronously therewith. When the placement plate 2 moves downward, the connecting strip 503 will be folded, and the bottom end of the connecting strip 503 will push the mounting block 502 to slide along the limiting rod 501. At this time, the spring 2 504 is shortened by the force, and its reaction force can resist the movement of the mounting block 502. The damper 505 can prevent the mounting block 502 from returning to its original position quickly, avoiding an increase in the amplitude of the crusher's operation, thereby ensuring a better noise reduction effect of the device. Moreover, under the restriction of multiple connecting strips 503, the crusher is more stable and will not swing at will.

[0025] like Figure 2 and Figure 4 As shown, a stabilizing component 6 is installed on the outside of the installation frame 1, and the stabilizing component 6 includes two limiting vertical grooves 603 opened in the middle of the outer walls at both ends of the installation frame 1, and an extrusion plate 604 is slidably connected in the two limiting vertical grooves 603. Two symmetrically arranged limiting oblique grooves 601 are opened on the outer walls at both ends of the installation frame 1, and a support column 602 is slidably connected inside the multiple limiting oblique grooves 601. The two extrusion plates 604 are respectively located at the top position of the two support columns 602 at one end, and the top inner walls of the multiple limiting oblique grooves 601 are fixedly connected with springs three, and the three ends of the multiple springs are respectively fixedly connected to the multiple support columns 602.

[0026] Two convex plates 608 are provided in the middle of the outer walls at both ends of the mounting frame 1, and a same screw rod 605 is rotatably connected between the two convex plates 608 at one end, and the two screw rods 605 are respectively threadedly connected to the two extrusion plates 604, and a bevel gear 2 609 is rotatably connected to the bottom outer walls of the two convex plates 608 at the bottom, and the two bevel gears 609 are coaxially fixed to one end of the bottom of the two screw rods 605.

[0027] A double-headed motor 606 is fixedly installed in the middle of the outer wall at the bottom of the installation frame 1. A bevel gear 1 607 is coaxially fixed to the two rotating shafts of the double-headed motor 606. The two bevel gears 1 607 are respectively meshed with the two bevel gears 2 609.

[0028] When in use, the support area of ​​the device can be increased by adjusting the stabilizing component 6, thereby ensuring that the device is more stable. The double-headed motor 606 is started, and the double-headed motor 606 drives the bevel gear 1 607 to rotate. The bevel gear 1 607 drives the bevel gear 2 609 to rotate through meshing. The bevel gear 2 609 drives the screw rod 605 to rotate. The extrusion plate 604 restricted by the limiting vertical groove 603 will move downward under the drive of the screw rod 605. The extrusion plate 604 drives the support column 602 to overcome the pulling force of the spring three and slide downward along the limiting inclined groove 601. When the support column 602 contacts the ground, the support area of ​​the mounting frame 1 is also increased accordingly.

[0029] like Figure 3 As shown, a plurality of telescopic rods 3 are fixedly connected to the middle of the bottom inner wall of the installation frame 1, and the top ends of the plurality of telescopic rods 3 are fixedly connected to the bottom outer wall of the placement plate 2. A spring 4 is sleeved on the outside of the plurality of telescopic rods 3, which ensures that the placement plate 2 can move normally while increasing the supporting performance of the placement plate 2.

[0030] like Figure 2 As shown, the outer walls of the bottoms of the plurality of support columns 602 are all provided with rubber gaskets so that when the device vibrates, it will not produce excessive collision with the ground.

[0031] The utility model provides a noise reduction base for a cone crusher, and the specific working principle is as follows:

[0032] When the device is working, the crusher is first fixed on the top of the placement plate 2. As the crusher vibrates during operation, the placement plate 2 moves synchronously. When the placement plate 2 moves downward, the connecting strip 503 is driven to fold, and one end of the bottom of the connecting strip 503 pushes the mounting block 502 to slide along the limit rod 501. At this time, the spring 2 504 is shortened by the force, and its reaction force can resist the movement of the mounting block 502. The damper 505 can prevent the mounting block 502 from returning to its original position quickly, avoiding an increase in the amplitude of the crusher's operation, thereby ensuring a better noise reduction effect of the device, and under the restriction of multiple connecting strips 503, the crusher state is more stable. It will not swing at will, and when in use, the support area of ​​the device can be increased by adjusting the stabilizing component 6, thereby ensuring that the device is more stable. Start the double-headed motor 606, and the double-headed motor 606 drives the bevel gear 1 607 to rotate. The bevel gear 1 607 drives the bevel gear 2 609 to rotate through meshing. The bevel gear 2 609 drives the screw rod 605 to rotate. The extrusion plate 604 limited by the limiting vertical groove 603 will move downward under the drive of the screw rod 605. The extrusion plate 604 drives the support column 602 to overcome the pulling force of the spring three and slide downward along the limiting inclined groove 601. When the support column 602 contacts the ground, the support area of ​​the mounting frame 1 is also increased accordingly.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
