Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically to a vibration damping base for a sand and gravel aggregate vibrating screen. Background Technology

[0002] A vibrating screen operates by utilizing the reciprocating rotary vibration generated by a vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar rotary vibration, while the lower rotating weight causes it to produce conical rotary vibration. The combined effect of these two forces results in a complex rotary vibration of the screen surface, with a vibration trajectory that is a complex spatial curve. This curve projects as a circle on the horizontal plane and as an ellipse on the vertical plane. Adjusting the excitation force of the upper and lower rotating weights changes the amplitude, while adjusting the spatial phase angle of the upper and lower weights changes the shape of the screen surface's motion trajectory and thus alters the material's movement trajectory on the screen surface. The bottom of the vibrating screen is equipped with a shock-absorbing base.

[0003] Existing vibrating screen damping bases are usually equipped with multiple sets of dampers to reduce vibration and reduce shaking during operation. The damping base is usually connected to the vibrating screen by bolts. The vibration generated by the vibrating screen during operation can cause the bolts to loosen, leading to the separation of the damping base from the vibrating screen. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping base for a sand and gravel aggregate vibrating screen, comprising a vibration damping base body and a fixing part. The fixing part is disposed above the vibration damping base body and has an installation frame connected to the upper part of the vibration damping base body.

A side block is slidably connected to the inner side of the fixing frame, and the central groove of the side block is in contact with the fixing block. The horizontal movement of the side block drives the vertical movement of the fixing block, causing the spring to deform.

[0006] By adopting the above technical solution, the fixed frame can be driven to move horizontally by rotating the bidirectional screw. The movement of the fixed frame causes the side block to fit into the vibrating screen base, and the side block will drive the fixed block to move vertically so that its bottom protrusion is inserted into the base hole for fixation. The operation process is simple and the fixing effect is good.

[0007] Preferably, the outer wall of the mounting frame is connected to a limiting frame, and the inner side of the limiting frame is rotatably connected to a limiting rod, and the limiting rod is in contact with the bidirectional screw.

[0010] By adopting the above technical solution, the guide rod can limit the position of the fixed block, thereby improving the stability of the fixed block during vertical movement.

[0011] Preferably, the guide rod is a cylinder, and the guide rod passes through the hole formed in the center of the spring.

[0012] By adopting the above technical solution, the guide rod can limit the spring and reduce the occurrence of spring deformation and misalignment.

[0013] Preferably, the groove of the side block is a sloped structure, and the top surface of the fixing block is a sloped structure, and the sloped surface of the side block fits into the sloped surface of the fixing block.

[0014] By adopting the above technical solution, the horizontal movement of the side block can drive the vertical movement of the fixed block.

[0015] Preferably, the side block is fixedly connected to a sliding rod inside the fixed frame, and the sliding rod is slidably connected to the fixed frame.

[0016] By adopting the above technical solution, the side block is limited by the sliding rod, thus preventing the side block from detaching from the fixed frame.

[0017] Preferably, the limiting rod has a curved groove, and a rubber pad is provided on the inner side of the curved groove, and the deformation of the rubber pad is in contact with the bidirectional screw.

[0018] By adopting the above technical solution, the friction of the bidirectional screw is limited by the friction of the rubber pad, thus preventing the bidirectional screw from rotating due to external influences.

[0019] Preferably, a magnetic block is fixedly connected to the outside of the mounting frame, and the magnetic block is in contact with the limiting rod.

[0020] By adopting the above technical solution, the magnetic block can be used to limit the position of the limiting rod, thereby improving the fixing effect of the limiting rod on the bidirectional screw.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0032] Example 1

[0033] Please see Figure 1-4This embodiment provides a technical solution: a vibration damping base for a sand and gravel aggregate vibrating screen, including a vibration damping base body 1 and a fixing part 2. The vibration damping base body 1 is equipped with multiple sets of dampers to dampen the vibration of the vibrating screen and prevent it from overturning due to excessive vibration. The fixing part 2 is located above the vibration damping base body 1 and has a mounting frame 201 connected to the top of the vibration damping base body 1. The mounting frame 201 is connected to the vibration damping base body 1 by welding to ensure the stability of the overall structure. A bidirectional screw 202 is rotatably connected inside the mounting frame 201. The bidirectional screw 202 is made of stainless steel to prevent rusting during long-term use. The threaded grooves at both ends of the bidirectional screw 202 are threaded to the fixing frames 203. The rotation of the bidirectional screw 202 can drive the two sets of fixing frames 203 to move horizontally in opposite directions. A spring 205 is connected to the inner side of the fixing frame 203. The fixing frame 203 is connected to the spring 205 by a buckle. Figure 3 The spring 205 is in a slightly compressed deformation state, and a fixing block 206 is connected to the top of the spring 205. The fixing block 206 is connected to the spring 205 by a buckle. The downward movement of the fixing block 206 will cause the spring 205 to deform. A side block 204 is slidably connected to the inner side of the fixing frame 203. The side block 204 is made of stainless steel to reduce wear during use. The central groove of the side block 204 fits against the fixing block 206. The horizontal movement of the side block 204 can drive the fixing block 206 to move vertically. The horizontal movement of the side block 204 drives the vertical movement of the fixing block 206, causing the spring 205 to deform.

[0034] Example 2

[0035] Please see Figure 1-4 A limiting frame 209 is connected to the outer wall of the mounting frame 201. The limiting frame 209 is welded to the outer wall of the mounting frame 201, and a limiting rod 210 is rotatably connected to the inner side of the limiting frame 209. The limiting rod 210 is made of stainless steel to prevent rusting during long-term use. The limiting rod 210 is in contact with the bidirectional screw 202, and the limiting rod 210 limits the bidirectional screw 202 to prevent it from loosening due to vibration. A guide rod 207 is fixedly connected to the inner side of the fixing frame 203, and the guide rod 207 is slidably connected to the fixing block 206. The guide rod 207 can limit the fixing block 206, improving the stability of the fixing block 206 during vertical movement.

[0036] The guide rod 207 is cylindrical and passes through the hole formed in the center of the spring 205. The guide rod 207 can limit the movement of the spring 205, reducing the possibility of deformation and misalignment. The groove of the side block 204 is a sloping structure, and the top surface of the fixing block 206 is also a sloping structure. The sloping surfaces of the side block 204 and the fixing block 206 are in contact. Horizontal movement of the side block 204 can drive vertical movement of the fixing block 206. A sliding rod 208 is fixedly connected to the side block 204 inside the fixing frame 203, and the sliding rod 208 is slidably connected to the fixing frame 203. The side block 204 is limited to prevent it from detaching from the fixed frame 203. The limiting rod 210 has a curved groove with a rubber pad inside. The rubber pad deforms and fits against the bidirectional screw 202. The friction of the rubber pad limits the bidirectional screw 202, preventing it from rotating due to external influences. A magnetic block 211 is fixedly connected to the outside of the mounting frame 201 and fits against the limiting rod 210. The magnetic block 211 limits the limiting rod 210, improving its fixing effect on the bidirectional screw 202.

[0037] Working principle: First, when it is necessary to fix the vibrating screen, place the vibrating screen on the mounting frame 201, then rotate the limit rod 210 to separate the bidirectional screw 202. Then rotate the bidirectional screw 202. Since the threaded groove of the bidirectional screw 202 is threadedly connected to the fixed frame 203, and the fixed frame 203 is slidably connected to the housing of the mounting frame 201, the rotation of the bidirectional screw 202 will drive the fixed frame 203 to move horizontally. The horizontal movement of the fixed frame 203 will drive the side block 204 to move horizontally. The side block 204 moves and fits against the side of the vibrating screen base.

[0038] Secondly, after the side block 204 is attached to the base, the bidirectional screw 202 is still rotated. The rotation of the bidirectional screw 202 will drive the fixed frame 203 to move. Since the fixed frame 203 and the side block 204 are slidably connected, the movement of the fixed frame 203 will house the side block 204 inside the fixed frame 203. Since the inclined surface of the side block 204 is attached to the inclined surface of the fixed block 206, the horizontal movement of the side block 204 will drive the fixed block 206 to move vertically. The vertical movement of the fixed block 206 will cause the bottom protrusion to insert into the hole of the vibrating screen base, completing the installation of the vibrating screen. Then, the limiting rod 210 is rotated in the opposite direction to make it attach to the bidirectional screw 202. The limiting rod 210 is used to reinforce the bidirectional screw 202 to prevent the bidirectional screw 202 from rotating due to external influences.
