Description

Technical Field

[0001] The utility model belongs to the technical field of cone crusher structure design, in particular to an anti-accumulation structure of a cone crusher. Background Art

[0002] Cone crusher is an industrial equipment used to crush various materials into smaller particles or powders. It usually consists of a conical crushing chamber, a rotating crushing head and a set of transmission systems. It is suitable for processing a variety of materials such as ores, minerals, construction waste, chemical raw materials, etc. The working principle of the cone crusher is to crush and grind the materials through the rotating crushing head to achieve the crushing effect. According to the different material hardness and particle size requirements, the parameters and settings of the crusher can be adjusted to achieve the best crushing effect. In industrial production, cone crushers are widely used in mining, metallurgy, construction, chemical industry and other industries, playing a key role in the fine and medium crushing of raw materials.

[0003] The top feed of the existing cone crusher is easily blocked when working, and there is no anti-material accumulation structure, which easily affects the processing continuity and slows down the production speed. Utility Model Content

[0004] The utility model aims to provide a material accumulation prevention structure for a cone crusher to solve the problems existing in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A material accumulation prevention structure for a cone crusher comprises a material discharge device, a rotating device is arranged at the bottom of the material discharge device; the rotating device comprises two symmetrically arranged brackets, a support shaft is rotatably arranged at the top of the bracket, two cams are symmetrically arranged in the middle of the support shaft, a second pulley is arranged at the front end of the bracket, a first pulley is arranged inside the second pulley, a belt is arranged between the first pulley and the second pulley, the material discharge device comprises a base, a processing machine is installed at the bottom of the base, a material discharge barrel is rotatably arranged at the top of the base, four rollers are symmetrically rotatably arranged at the bottom of the material discharge barrel, a rotating shaft is rotatably arranged in front of the base, a motor is installed at the front end of the rotating shaft, the material discharge barrel is funnel-shaped, and the rollers are hinged to the material discharge barrel.

[0007] Furthermore: the motor is connected to the base by bolts.

[0008] Furthermore: the first pulley is key-connected to the rotating shaft.

[0009] Furthermore: the support shaft is connected to the bracket bearing, and the bracket and the base are welded together.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The base supports the motor to drive the shaft to rotate, and at the same time drives the two first pulleys to rotate. The two first pulleys drive the second pulleys on both sides to rotate through belts respectively. The second pulleys drive the support shaft to rotate synchronously under the support of the bracket, and the support shaft drives the cam to rotate. Since the left and right cams are installed in opposite directions, when the left cam pushes the roller upward, the right cam does not drive the upper roller to move upward. At this time, the unloading barrel tilts to the right under the support of the base. Similarly, when the right cam drives the roller to move upward, the unloading barrel tilts to the left, thereby realizing the repeated shaking of the unloading barrel from left to right, so that the materials stored in it can fall smoothly, preventing material accumulation, increasing the unloading speed, facilitating large-scale continuous processing, and improving production speed.

[0020] See also Figure 1-Figure 3 A material accumulation prevention structure of a cone crusher includes a material discharge device 1, and a rotating device 2 is arranged at the bottom of the material discharge device 1.

[0021] In this embodiment: the unloading device 1 includes a base 101, a processing machine 102 is installed at the bottom of the base 101, a unloading barrel 103 is rotatably arranged on the top of the base 101, four rollers 104 are symmetrically rotatably arranged at the bottom of the unloading barrel 103, a rotating shaft 105 is rotatably arranged in front of the base 101, a motor 106 is installed at the front end of the rotating shaft 105, the motor 106 is bolted to the base 101, the unloading barrel 103 is funnel-shaped, the rollers 104 are hinged to the unloading barrel 103, the material to be crushed is poured into the unloading barrel 103, and then falls into the processing machine 102 to complete the crushing, in order to prevent the material from being blocked in the unloading barrel 103, the base 101 supports the motor 106 to drive the rotating shaft 105 to rotate, and at the same time drives the two first pulleys 202 to rotate;

[0022] In this embodiment, the rotating device 2 includes two symmetrically arranged brackets 201, a support shaft 205 is rotatably arranged on the top of the bracket 201, two cams 206 are symmetrically arranged in the middle of the support shaft 205, a second pulley 203 is arranged at the front end of the bracket 201, a first pulley 202 is arranged inside the second pulley 203, a belt 204 is arranged between the first pulley 202 and the second pulley 203, the first pulley 202 is connected to the rotating shaft 105 with a flat key, the first pulley 202 is connected to the rotating shaft 105 with a flat key, the support shaft 205 is connected to the bracket 201 bearing, the bracket 201 is welded to the base 101, and the two first pulleys 202 drive the second pulleys on both sides through the belt 204. As the wheel 203 rotates, the second pulley 203 drives the support shaft 205 to rotate synchronously under the support of the bracket 201, and the support shaft 205 drives the cam 206 to rotate. Since the left and right cams 206 are installed in opposite directions, when the left cam 206 pushes the roller 104 upward, the right cam 206 does not drive the upper roller 104 to move upward. At this time, the unloading barrel 103 tilts to the right under the support of the base 101. Similarly, when the right cam 206 drives the roller 104 to move upward, the unloading barrel 103 tilts to the left, thereby realizing the repeated shaking of the unloading barrel 103 left and right, so that the materials stored in it can fall smoothly, prevent material accumulation, increase the unloading speed, facilitate large-scale continuous processing, and increase production speed.

[0023] Working principle: the material to be crushed is poured into the discharge barrel 103, and then falls into the processing machine 102 to complete the crushing. In order to prevent the material from being blocked in the discharge barrel 103, the base 101 supports the motor 106 to drive the rotating shaft 105 to rotate, and at the same time drives the two first pulleys 202 to rotate. The two first pulleys 202 respectively drive the second pulleys 203 on both sides to rotate through the belt 204. The second pulley 203 drives the support shaft 205 to rotate synchronously under the support of the bracket 201, and the support shaft 205 drives the cam 206 to rotate. The left and right cams 206 are installed in opposite directions. Therefore, when the left cam 206 pushes the roller 104 upward, the right cam 206 does not drive the roller 104 on it to move upward. At this time, the unloading barrel 103 tilts to the right under the support of the base 101. Similarly, when the right cam 206 drives the roller 104 to move upward, the unloading barrel 103 tilts to the left. This realizes the repeated shaking of the unloading barrel 103 left and right, so that the materials stored in it can fall smoothly, prevent material accumulation, increase the unloading speed, facilitate large-scale continuous processing, and increase production speed.
