Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically to an intelligent monitoring and early warning device for material blockage in crushers. Background Technology

[0002] A crusher, also known as a stone crusher, is a pulverizing machine used in the processing of metal and non-metal minerals to break mined raw ore into small particles through compression and bending.

[0003] In existing crushers, the internal liner and crushing roller are mostly fixed structures. When the ore passes between them, it is subjected to rigid compression. However, if the volume of the ore matches the size of the gap, it will not be able to be effectively crushed, resulting in material blockage. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent monitoring and early warning device for material blockage in a crusher. By automatically adjusting the position of the arc-shaped liner through hydraulic components, the crushing gap is temporarily increased, and the blocked material is actively discharged. Since it can effectively avoid and quickly resolve material blockage, the crusher no longer needs to be stopped frequently for manual cleaning, and the effective working time is greatly increased, which can solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent monitoring and early warning device for material blockage in a crusher, comprising a crusher box, a feeding window provided above one end of the crusher box, and a discharge window provided at the other end of the crusher box, wherein a sensing sleeve is installed below the discharge window, a transmission pulley is installed on one side of the crusher box, and a cross rocker arm is installed inside the crusher box, the cross rocker arm is connected to the transmission pulley through a transmission shaft, and the cross rocker arm is rotatably connected to the crusher box.

[0006] Preferably, an eccentric roller and a crushing roller are respectively installed around the cross rocker arm, wherein the crushing roller is rotatably connected to the cross rocker arm, and an eccentric ball is installed inside the eccentric roller.

[0007] Preferably, an impact liner is installed on one side of the cross rocker arm, and the impact liner is connected to the crusher box by bolts.

[0008] Preferably, a base is installed below the cross rocker arm, and the base is slidably connected to the crusher box via a track.

[0009] Preferably, an arc-shaped liner is bolted to the inner side of the base, and the outer surface of the arc-shaped liner has a toothed groove structure.

[0010] Preferably, one end of the base is equipped with a transfer shaft, which is rotatably connected to the base.

[0011] Preferably, a sensing coupling is installed at one end of the adapter shaft, and the sensing coupling is connected to the adapter shaft by bolts.

[0012] Preferably, the sensing coupling extends into the interior of the sensing sleeve, which includes a sensor and a hydraulic assembly.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by timely unloading abnormal loads, prevents stress accumulation from causing impact damage to key components such as the drive shaft, cross rocker arm, and crushing roller, thus playing the role of overload protection, thereby extending the service life of the entire equipment and reducing maintenance costs.

[0015] 2. This utility model automatically adjusts the position of the arc-shaped liner through hydraulic components, temporarily increasing the crushing gap and actively expelling stuck material. Since it can effectively avoid and quickly remove material blockage, the crusher no longer needs to be stopped frequently for manual cleaning, and the effective working time is greatly increased.

[0020] 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.

[0021] To address the issue that existing crushers often have a fixed structure between the internal liner and the crushing roller, resulting in rigid compression of the ore as it passes between them, and the inability to effectively crush the ore if its volume matches the gap size, leading to material blockage; please refer to... Figure 1-3The present invention provides the following solution:

[0022] A smart monitoring and early warning device for material blockage in a crusher includes a crusher box 1. A feeding window 101 is provided on the upper part of one end of the crusher box 1, and a discharge window 102 is provided on the other end of the crusher box 1. A sensing sleeve shaft 2 is installed below the discharge window 102. A transmission pulley 3 is installed on one side of the crusher box 1. A cross rocker arm 303 is installed inside the crusher box 1. The cross rocker arm 303 is connected to the transmission pulley 3 through a transmission shaft, and the cross rocker arm 303 is rotatably connected to the crusher box 1.

[0023] In this embodiment, the ore material enters the crusher box 1 through the feeding window 101. Power is transmitted through the transmission pulley 3 and drives the cross rocker arm 303 to rotate via the transmission shaft. The eccentric roller 301 and the crushing roller 302 mounted on the cross rocker arm 303 then revolve. The crushing roller 302 can also rotate relative to the cross rocker arm 303.

[0024] Eccentric rollers 301 and crushing rollers 302 are respectively installed around the cross rocker arm 303. The crushing rollers 302 are rotatably connected to the cross rocker arm 303, and eccentric balls are installed inside the eccentric rollers 301. An impact liner 4 is installed on one side of the cross rocker arm 303. The impact liner 4 is bolted to the crusher box 1. A base support 203 is installed below the cross rocker arm 303. The base support 203 is slidably connected to the crusher box 1 via a track.

[0025] In this embodiment, the material is first violently hammered by the eccentric roller hammer 301. The centrifugal force generated by the eccentric ball inside the eccentric roller hammer 301 further enhances the crushing effect, achieving primary crushing of large pieces of ore. The crushed material falls onto the arc-shaped liner 204. The rotating cross rocker arm 303 drives the crushing roller 302 to roll on the surface of the arc-shaped liner 204 with a toothed structure, crushing and grinding the material between the two, achieving secondary fine crushing. The material that is not completely crushed may be thrown to one side of the impact liner 4 and crushed again by impacting the impact liner 4. Finally, the crushed material that meets the particle size requirements is discharged from the discharge window 102.

[0026] An arc-shaped liner 204 is bolted to the inner side of the base 203. The outer surface of the arc-shaped liner 204 is provided with a toothed groove structure. A transfer shaft 202 is installed at one end of the base 203. The transfer shaft 202 is rotatably connected to the base 203. A sensing coupling 201 is installed at one end of the transfer shaft 202. The sensing coupling 201 is bolted to the transfer shaft 202. The sensing coupling 201 extends into the interior of the sensing sleeve 2. The sensing sleeve 2 includes a sensor and a hydraulic component.

[0027] In this embodiment, when the volume of ore entering the crushing chamber matches the gap between the crushing roller 302 and the arc-shaped liner 204, or when there is too much material, the crushing resistance will increase sharply. The huge abnormal resistance will be transmitted upward. The end of the bottom support 203 is connected to the transfer shaft 202, and the transfer shaft 202 is fixedly connected to the sensing coupling 201. The displacement sensor integrated inside the sensing sleeve 2 can monitor the small displacement generated by the sensing coupling 201 in real time. When the pressure or displacement value exceeds the preset safety threshold, the hydraulic component drives the sensing coupling 201, and then controls the bottom support 203 to slide along the track through the transfer shaft 202, so that the arc-shaped liner 204 installed on it can temporarily move away from the crushing roller 302, instantly increase the crushing gap, allow the stuck material to pass through, and thus automatically release the blockage state.
