Description

Technical Field

[0001] This utility model relates to the field of coal conveying technology in chutes, specifically to a fishbone vibration unblocking device for use inside chutes. Background Technology

[0002] A coal chute, also known as a chute or coal conveyor, is a simple device used to transport solid materials such as coal and ore. It plays a crucial role in coal mining and transportation, effectively moving coal from one location to another, and is typically used in underground mines or coal preparation plants. In coal conveying systems, especially when transporting wet, sticky coal, clogging is a common problem due to the high coefficient of friction between the wet, sticky coal surface and the chute.

[0003] Currently, vibration devices are installed on the sides or bottom of coal chutes. However, these vibration devices can only transmit vibration to a local area of ​​the coal chute. For example, the vibration is transmitted only at a certain point on the side or bottom of the coal chute, which makes the vibration effect in the coal chute uneven and results in low dredging efficiency in actual application. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fishbone vibration unblocking device for the inside of a chute. The vibration striking component of the device is like a fishbone of the same length. When the vibration striking component strikes the bottom of the coal chute, its striking point is distributed throughout the entire bottom of the chute, and the vibration felt by the coal chute is uniform, which makes the unblocking effect of the coal chute better and the unblocking efficiency of wet and sticky coal higher.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A fishbone vibration unblocking device for the inside of a chute includes a coal chute; a set of vibration striking components are installed at equal intervals at the bottom of the coal chute, and the two ends of the vibration striking components are respectively connected to elastic boosting mechanisms fixedly installed on both sides of the coal chute. The vibration striking components can abut against the bottom of the coal chute under the push of the elastic boosting mechanisms.

[0007] A vibration drive mechanism is also fixedly installed on any of the elastic booster mechanisms. The vibration drive mechanism continuously acts on the elastic booster mechanism to make the vibration striking component reciprocate to strike the bottom of the coal chute, thereby preventing the wet and sticky coal in the coal chute from causing blockage.

[0008] The vibration striking assembly includes a horizontally positioned striking frame, which resembles the spine of a fish skeleton; the striking frame is equipped with multiple striking rods that are evenly distributed on the bottom of the coal chute and vertically positioned, which resemble the bony spikes on both sides of a fish skeleton.

[0009] Using the above scheme, the vibration striking component of the device is like a fishbone of the same length. When the vibration striking component strikes the bottom of the coal chute, its striking point covers the entire bottom of the chute, and the vibration felt by the coal chute is uniform, which makes the unblocking effect of the coal chute better and the transportation of wet and sticky coal will be smoother.

[0010] In a preferred embodiment of a fishbone vibration unblocking device for use inside a chute, the striking rod is detachably and through-mounted inside the striking frame, and the striking rod and the striking frame are simultaneously connected by a pin on the side of the striking frame; wherein the interior of the striking frame is hollow, and the pin is interference-fitted into the striking rod and the striking frame.

[0011] Using the above solution, since the striking rod will wear down its end due to long-term striking of the bottom of the coal chute, it is connected by a pin to facilitate replacement. When replacing, only the pin needs to be pulled out, which is simple to operate and convenient to replace.

[0012] In a preferred embodiment of a fishbone vibration unblocking device for use inside a chute, the elastic booster mechanism includes a main frame, a vertically arranged guide rod fixed at the bottom of the main frame, a slide block slidably mounted on the guide rod, the slide block being fixedly connected to both ends of the striking frame, and a spring fitted on the guide rod to push the slide block upward.

[0013] In order to achieve the elastic push of the vibration striking component using the above scheme, the slide block is pushed upward by the spring, thereby driving the entire vibration striking component upward.

[0014] In a preferred embodiment of a fishbone vibration unblocking device for use inside a chute, the elastic booster mechanism further includes an N-shaped positioning seat fixed to the top of the main frame. The side of the N-shaped positioning seat is threadedly fitted with a set screw, and the inner end of the set screw is fixed with a clamp that abuts against the side wall of the coal chute.

[0015] With the above solution, in order to facilitate the installation and disassembly of the elastic booster mechanism, the clamp can be quickly tightened or loosened by rotating the set screw, which makes it more convenient to use.

[0016] In a preferred embodiment of a fishbone vibration unblocking device for use inside a chute, the vibration drive mechanism includes a motor base fixedly installed on any part of the main frame, a drive motor fixed on the motor base, a drive disk concentrically connected to the shaft of the drive motor, and a drive rod installed on the drive disk; a trigger disk is also fixed on a nearby slide, and when the drive rod is driven to rotate, it can contact the trigger disk and cause the slide to slide downward.

[0017] Using the above scheme, in order to achieve the reciprocating vibration of the vibration striking component, the initial state of the drive rod before the drive rotation is horizontal, and the striking rod is pushed by the spring against the bottom of the coal chute. At this time, the drive rod is just not in contact with the trigger plate. When the drive motor drives the drive rod to rotate, the drive rod rotates and presses the trigger plate, causing the slide to slide downward. Once the drive rod is out of contact with the trigger plate, the striking rod is pushed by the spring to strike the bottom of the coal chute, and so on, to achieve uniform vibration in the coal chute.

[0018] In a preferred embodiment of a fishbone vibration unblocking device for use inside a chute, the drive rod is detachably and through-mounted inside the drive disc, and the drive rod and the drive disc are simultaneously connected on the front side of the drive disc by a second pin, which is interference-fitted into the drive rod and the drive disc.

[0019] Using the above solution, since the drive rod will wear down its side due to long-term contact with the trigger disc, in order to facilitate the replacement of the drive rod, it is connected by a second pin. When replacing, only the second pin needs to be pulled out. The operation is simple and the replacement is convenient.

[0020] After adopting the above technical solution, the beneficial effects of this utility model are:

[0021] 1. The vibration striking component of this device is like a fishbone of the same length. When the vibration striking component strikes the bottom of the coal chute, its striking point covers the entire bottom of the chute, and the vibration felt by the coal chute is uniform, which makes the coal chute clearing effect better and the unblocking efficiency of wet and sticky coal higher.

[0022] 2. Because the striking rod will wear down its end due to long-term striking of the bottom of the coal chute, it is connected by a pin to facilitate replacement. When replacing, simply pull out the pin. The operation is simple and the replacement is convenient.

[0023] 3. In order to achieve the elastic push of the vibration and striking component, the spring pushes the slide block upward, thereby driving the entire vibration and striking component upward;

[0024] 4. To facilitate the installation and disassembly of the elastic booster mechanism, the clamp can be quickly tightened or loosened by rotating the set screw, making it more convenient to use.

[0025] 5. In order to achieve the reciprocating vibration of the vibration striking component, the initial state of the drive rod before the drive rotation is horizontal. The striking rod is pushed by the spring and abuts against the bottom of the coal chute. At this time, the drive rod is just not in contact with the trigger plate. When the drive motor drives the drive rod to rotate, the drive rod rotates and presses the trigger plate, causing the slide to slide downward. Once the drive rod is out of contact with the trigger plate, the striking rod is pushed by the spring and strikes the bottom of the coal chute. This reciprocating striking is performed to achieve uniform vibration in the coal chute.

[0026] 6. Since the drive rod will wear down on its side due to long-term contact with the trigger plate, it is connected by a second pin to facilitate replacement. When replacing, simply pull out the second pin. The operation is simple and the replacement is convenient. Attached Figure Description

Detailed Implementation

[0039] 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.

[0040] like Figures 1 to 4 As shown, a fishbone vibration unblocking device for the inside of a chute includes a coal chute 1; a set of vibration striking components 2 are installed at intervals of 3-5 meters at the bottom of the coal chute 1, and the two ends of the vibration striking components 2 are respectively connected to elastic boosting mechanisms 3 fixedly installed on both sides of the coal chute 1. The vibration striking components 2 can reach the bottom of the coal chute 1 under the push of the elastic boosting mechanisms 3; a vibration driving mechanism 4 is also fixedly installed on any of the elastic boosting mechanisms 3. The vibration driving mechanism 4 continuously acts on the elastic boosting mechanisms 3 to make the vibration striking components 2 reciprocate to strike the bottom of the coal chute 1, thereby avoiding blockage caused by wet and sticky coal in the coal chute 1; the vibration striking components 2 include a horizontally arranged striking frame 201, which is like the spine in the middle of a fishbone; multiple striking rods 202 are installed on the striking frame 201, which are evenly distributed on the bottom of the coal chute 1 and vertically arranged, and the striking rods 202 are like the bony spikes on both sides of the fishbone. The vibrating striking component 2 of the device is like a fishbone of the same length. When the vibrating striking component 2 strikes the bottom of the coal chute 1, its striking point is distributed throughout the entire bottom of the chute, and the vibration felt by the coal chute 1 is uniform, which makes the unblocking effect of the coal chute 1 better and the unblocking efficiency of wet and sticky coal higher.

[0041] like Figure 5As shown, the striking rod 202 is detachably and continuously installed inside the striking frame 201, and is simultaneously connected to the striking frame 201 via a pin 203 on the side of the striking frame 201. The striking frame 201 is hollow, and the pin 203 is interference-fitted into both the striking rod 202 and the striking frame 201. Because the striking rod 202 will wear down at its end due to prolonged striking of the bottom of the coal chute 1, it is connected via pin 203 for easy replacement. Replacement only requires pulling out pin 203, making the operation simple and convenient.

[0042] like Figures 6 to 7 As shown, the elastic boosting mechanism 3 includes a main frame 301. A vertically arranged guide rod 302 is welded and fixed to the bottom of the main frame 301. A slide block 303 is slidably mounted on the guide rod 302. The slide block 303 is fixedly connected to both ends of the striking frame 201 by screws. A spring 304 is fitted on the guide rod 302 to push the slide block 303 upward. In order to achieve the elastic push of the vibration striking assembly 2, the spring 304 pushes the slide block 303 upward, thereby driving the vibration striking assembly 2 as a whole to push upward.

[0043] like Figures 6 to 7 As shown, the elastic booster mechanism 3 also includes an N-shaped positioning seat 305 welded and fixed to the top of the main frame 301. A set screw 306 is threaded through the side of the N-shaped positioning seat 305, and a clamping seat 307 is welded and fixed to the inner end of the set screw 306, abutting against the side wall of the coal chute 1. To facilitate the installation and disassembly of the elastic booster mechanism 3, the clamping seat 307 can be quickly tightened or loosened by rotating the set screw 306, making it more convenient in application.

[0044] like Figures 8 to 9As shown, the vibration drive mechanism 4 includes a motor base 401 fixedly mounted on the main frame 301 at any point by screws. A drive motor 402 is fixed to the motor base 401 by screws. A drive disk 403 is concentrically connected to the shaft of the drive motor 402 by screws. A drive rod 404 is mounted on the drive disk 403. A trigger disk 405 is also welded and fixed to a nearby slide 303. When the drive rod 404 is driven to rotate, it can contact the trigger disk 405 and cause the slide 303 to slide downward. To achieve the reciprocating vibration of the vibration striking component 2, the drive rod 404 is initially in a horizontal state before the drive rotation. The striking rod 202 is pushed against the bottom of the coal chute 1 by the spring 304. At this time, the drive rod 404 is just not in contact with the trigger plate 405. When the drive motor 402 drives the drive rod 404 to rotate, the drive rod 404 rotates and presses the trigger plate 405, causing the slide 303 to slide downward. Once the drive rod 404 is out of contact with the trigger plate 405, the striking rod is pushed by the spring 304 to strike the bottom of the coal chute 1, and so on, to achieve uniform vibration in the coal chute 1.

[0045] like Figure 10 As shown, the drive rod 404 is detachably and continuously installed inside the drive plate 403. A second pin 406 connects the drive rod 404 and the drive plate 403 simultaneously on the front side of the drive plate 403. The second pin 406 is interference-fitted into the drive rod 404 and the drive plate 403. Since the drive rod 404 will wear down due to prolonged contact with the trigger plate 405, it is connected via the second pin 406 to facilitate replacement. Replacement only requires removing the second pin 406, making the operation simple and convenient.

[0046] The working principle of this utility model:

[0047] Before application, the clamping seat 307 can be quickly tightened by rotating the set screw 306, thereby clamping and fixing the elastic booster mechanism 3 to both sides of the coal chute 1.

[0048] Before the drive rod 404 rotates, it is initially in a horizontal state. The striking rod 202 is pushed by the spring 304 and abuts against the bottom of the coal chute 1. At this time, the drive rod 404 is just not in contact with the trigger plate 405. In application, the drive motor 402 is started, and the drive rod 404 is driven to rotate slowly. The drive rod 404 rotates and presses the trigger plate 405, causing the slide 303 to slide downward. Once the drive rod 404 is out of contact with the trigger plate 405, the striking rod is pushed by the spring 304 and strikes the bottom of the coal chute 1. This is repeated to achieve uniform vibration in the coal chute 1.

[0049] The vibratory tapping component 2 is like a fishbone of the same length. When the vibratory tapping component 2 taps the bottom of the coal chute 1, its tapping point covers the entire bottom of the chute, and the vibration felt by the coal chute 1 is uniform, which makes the coal chute 1 more effective at clearing blockages and more efficient at clearing wet and sticky coal.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
