Description

Technical Field

[0001] This utility model relates to the field of drop impact detection technology, specifically an automatic turning device for a mineral crusher. Background Technology

[0002] The main purpose of rotating the crusher is to ensure smooth operation during startup and avoid malfunctions caused by jammed or damaged parts. During rotation, operators can check for any obstructions, ensure there is adequate grease in the bearing housings, proper clearance between the hammers and toothed liners, and that all fasteners are secure.

[0003] Traditional rotary disc winding devices employ a worm gear and worm shaft mechanism, rotating the crusher rotor to achieve rotary disc winding. However, this method has a drawback: when the rotor needs to be stopped at a certain position, due to the rotor's inertia, the worm gear connected to it cannot stop rotating immediately and will continue to collide with the worm, leading to damage to the worm gear and worm shaft. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] An automatic turning device for a mineral crusher includes a turning mechanism and a damping mechanism. The turning mechanism includes a support plate, two bearing seats movably disposed on the top of the support plate, a worm gear rotatably connected between the two bearing seats, a motor fixedly connected to one end of the worm gear, a worm wheel meshing with the top of the worm gear, a main shaft detachably connected to the worm wheel, and an electric push rod fixedly connected between the support plate and the bearing seats. The damping mechanism includes three arc grooves formed on the front side of the worm wheel, three springs one fixedly connected to the three arc grooves, a sliding plate fixedly connected to the outer end of the spring one, a T-shaped insert rod slidably passing through the front side of the support plate, three springs two attached to the front side of the support plate and fixedly connected to the T-shaped insert rod, three arc rods surrounding the rear end of the T-shaped insert rod, and an insert plate fixedly connected to the rear end of the arc rods. The three insert plates are respectively attached to one side of the three sliding plates.

[0007] By adopting the above technical solution, when the worm gear stops at a certain position, the user pulls down the pressure rod, which, through leverage, causes the insert block to be inserted into the corresponding socket. At the same time, the bottom end of the curved rod touches the tactile switch. At this time, the insert block squeezes the inner wall of the socket, pushing the T-shaped insert rod to slide towards the worm gear, causing the arc rod and the insert plate to move together until they are in contact with the sliding plate. The worm gear, which continues to rotate due to inertia, forms a block against the insert plate through the spring and the sliding plate, causing the worm gear to stop quickly. At the same time, the tactile switch controls the movable ends of the two electric push rods to retract, causing the worm to descend and disengage from the worm gear, thereby avoiding a collision between the worm gear and the worm.

[0008] In a preferred embodiment, the present invention can be further configured as follows: a linkage component is provided on the rear side of the support plate, the linkage component includes a crank rod rotatably mounted on the rear side of the support plate, a plug block fixed to the top of the crank rod, and a tactile switch attached to the bottom of the crank rod and fixed to the support plate, wherein the T-shaped plug rod has a socket suitable for plug block insertion.

[0009] In a preferred embodiment, the present invention can be further configured such that two electric actuators are connected in series and electrically connected to a tactile switch.

[0010] In a preferred embodiment, the present invention can be further configured as follows: three arc grooves are equally spaced and arranged in a ring, and the rear end of the slide plate extends slidably into the interior of the arc grooves.

[0011] In a preferred embodiment, the present invention can be further configured such that: a plurality of guide rods are fixedly connected to the front side of the worm gear, and the plurality of guide rods are arranged in pairs, forming three groups, with the two guide rods in each group located on the inner and outer sides of the three arc grooves respectively.

[0012] In a preferred embodiment, the present invention can be further configured such that a pressure rod is fixedly connected to one side of the crank, and the pressure rod is located at the top of the tactile switch.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, when the worm gear is stopped at a certain position, the user pulls down the pressure rod, which, through leverage, causes the insert block to be inserted into the corresponding socket. At the same time, the bottom end of the curved rod touches the tactile switch. At this time, the insert block squeezes the inner wall of the socket, pushing the T-shaped insert rod to slide towards the worm gear, causing the arc rod and the insert plate to move together until they are in contact with the sliding plate. The worm gear, which continues to rotate due to inertia, forms a block against the insert plate through the spring and the sliding plate, causing the worm gear to stop quickly. At the same time, the tactile switch controls the movable ends of the two electric push rods to retract, causing the worm to descend and disengage from the worm gear, thereby avoiding a collision between the worm gear and the worm.

[0015] 2. In this utility model, when performing rotation, the user presses a touch switch to control the extension of the movable ends of the two electric push rods, driving the two bearing seats to raise the worm gear, so that the worm gear and worm wheel enter a meshing state. Subsequently, the motor drives the worm wheel to rotate through the worm gear, thereby driving the main shaft and the crusher rotor to rotate together, thus completing the detection of whether there is a risk of collision between the hammer and the liner. This eliminates the need for manual operation, realizes an automatic rotation detection mode, and improves the comfort of the detection. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0030] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0031] The following describes, with reference to the accompanying drawings, some embodiments of an automatic turning device for a mineral crusher.

[0032] Example 1:

[0033] Combination Figure 1-7 As shown, the present invention provides an automatic turning device for a ore crusher, including a turning mechanism 100 and a damping mechanism 200. The turning mechanism 100 includes a support plate 110, two bearing seats 120 movably disposed on the top of the support plate 110, a worm gear 130 rotatably connected between the two bearing seats 120, a motor 140 fixedly connected to one end of the worm gear 130, a worm wheel 150 meshing with the top of the worm gear 130, a main shaft 160 detachably connected to the worm wheel 150, and an electric push rod 170 fixedly connected between the support plate 110 and the bearing seats 120.

[0034] The damping mechanism 200 includes three arc grooves 210 formed on the front side of the worm gear 150, three springs 220 respectively fixed inside the three arc grooves 210, a sliding plate 230 fixed to the outer end of the springs 220, a T-shaped insert 240 slidably passing through the front side of the support plate 110, three springs 250 attached to the front side of the support plate 110 and fixed to the T-shaped insert 240, three arc rods 260 surrounding the rear end of the T-shaped insert 240, and an insert plate 270 fixed to the rear end of the arc rods 260. The three insert plates 270 are respectively attached to one side of the three sliding plates 230.

[0035] Furthermore, the three arc grooves 210 are equally spaced and arranged in a ring. The rear end of the slide plate 230 extends slidably into the interior of the arc grooves 210. The layout design of the three arc grooves 210 provides conditions for the three insert plates 270 to evenly resist the rotation of the worm gear 150.

[0036] Example 2:

[0037] Combination Figure 2 , 6 and Figure 7As shown, based on Embodiment 1, a linkage assembly 300 is provided on the rear side of the support plate 110. The linkage assembly 300 includes a crank rod 310 rotatably mounted on the rear side of the support plate 110, an insert block 320 fixed to the top of the crank rod 310, and a tactile switch 330 attached to the bottom of the crank rod 310 and fixed to the support plate 110. The T-shaped insert rod 240 has a socket suitable for inserting the insert block 320. Pressing down the crank rod 310 can cause the insert block 320 to squeeze the T-shaped insert rod 240, causing the insert plate 270 on the arc rod 260 to abut against the sliding plate 230. At the same time, by squeezing the tactile switch 330, the crank rod 310 can cause the movable end of the electric push rod 170 to retract, causing the worm gear 130 and the worm wheel 150 to separate, effectively preventing them from colliding.

[0038] Furthermore, the two electric push rods 170 are connected in series and electrically connected to the tactile switch 330. This structural design allows the two bearing seats 120 to rise and fall synchronously, preventing the worm gear 130 from getting stuck during the rising and falling process.

[0039] Furthermore, a pressure rod 500 is fixedly connected to one side of the crank 310. The pressure rod 500 is located on the top of the tactile switch 330. The pressure rod 500 is provided to facilitate the user to press down the crank 310 and improve the comfort of using the device.

[0040] Example 3:

[0041] Combination Figure 1 As shown in the above embodiment, a plurality of guide rods 400 are fixedly connected to the front side of the worm gear 150. The guide rods 400 are arranged in pairs, forming three groups. The two guide rods 400 in each group are located on the inner and outer sides of the three arc grooves 210, respectively. The guide rods 400 can guide the slide plate 230 to rotate, prevent the slide plate 230 from separating from the worm gear 150, and improve the stability of the overall structure of the device.

[0042] The working principle and usage process of this utility model are as follows: In the initial state, the main shaft 160 is fixedly connected to the crusher rotor; when rotating the machine, the user presses the touch switch 330 to control the movable ends of the two electric push rods 170 to extend, driving the two bearing seats 120 to drive the worm 130 to rise, so that the worm 130 and the worm wheel 150 enter the meshing state. Subsequently, the motor 140 drives the worm wheel 150 to rotate through the worm 130, thereby driving the main shaft 160 and the crusher rotor to rotate together, thus completing the detection of whether there is a risk of collision between the hammer and the liner.

[0043] Subsequently, when the worm gear 150 stops at a certain position, the user pulls down the lever 500, which, through leverage, causes the insert block 320 to insert into the corresponding socket. At the same time, the bottom end of the crank rod 310 presses the tactile switch 330. At this time, the insert block 320 squeezes the inner wall of the socket, pushing the T-shaped insert rod 240 to slide towards the worm gear 150, causing the arc rod 260 and the insert plate 270 to move accordingly until they are in contact with the sliding plate 230. Due to inertia, the worm gear 150 continues to rotate, and through the spring 220 and the sliding plate 230, it blocks the insert plate 270, causing the worm gear 150 to stop quickly. At the same time, the tactile switch 330 controls the movable ends of the two electric push rods 170 to retract, causing the worm 130 to descend and disengage from the worm gear 150, thereby avoiding a collision between the worm gear 150 and the worm 130.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
