Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically to an anti-clogging feed hopper structure for mining machinery. Background Technology

[0002] Mines include coal mines, metallic mines, non-metallic mines, building material mines, and chemical mines, among others. The size of a mine must be commensurate with its economically viable service life; only in this way can infrastructure costs be saved and expenses reduced. Mining machinery uses feed hoppers to collect ore during the mining process. The main ways to reduce mining costs are to improve labor productivity and product quality, and to reduce material consumption.

[0003] According to a mining machinery feed hopper (announcement number: CN211945450U) published in the above application, the coal blocks entering the feed hopper cannot be pre-crushed during use. Therefore, the feed hopper is prone to blockage during the feeding process. In order to solve this problem, we propose an anti-blockage feed hopper structure for mining machinery. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-clogging feed hopper structure for mining machinery to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clogging-resistant feed hopper structure for mining machinery, comprising a feed hopper body, a motor fixedly mounted on the surface of the feed hopper body, the output shaft of the motor fixedly connected to the surface of a crushing roller, the crushing roller rotatably connected to the inner wall of the feed hopper body, a screen plate fixedly mounted on the inner wall of the feed hopper body, a support frame fixedly mounted on the inner wall of the feed hopper body, and a control component disposed inside the feed hopper body, the control component comprising:

[0006] A lever, used to move the material on the surface of the sieve plate:

[0007] The slider is fitted against the inner wall of the support frame:

[0008] The movable rod connects the slider to the support rod.

[0009] The anti-clogging component is used to prevent the feed hopper body from becoming blocked, so that the crushed coal blocks can pass through the screen plate quickly and avoid stagnation that could cause blockage in the feed hopper body.

[0010] Preferably, the lever is fixedly installed on the surface of the slider, the slider is slidably connected to the inner wall of the support frame, the surface of the slider is hinged to one end of the movable rod, and the other end of the movable rod is hinged to the surface of the support rod. When the support rod moves longitudinally, the movable rod can be folded to push the slider to slide.

[0011] Preferably, the anti-blocking component includes a fixing rod, which is fixedly installed on the surface of the support frame. The fixing rod passes through the support rod and is slidably connected to the support rod. The surface of the support rod is fixedly connected to one end of a spring, and the other end of the spring is fixedly installed on the surface of the fixing rod. When the support rod is no longer resisted, it can spring up from the surface of the fixing rod under the support of the spring.

[0012] Preferably, the support frame is penetrated by the hammer rod and slidably connected to the hammer rod. The surface of the hammer rod is fixedly connected to one end of the second spring, and the other end of the second spring is fixedly installed on the surface of the support frame. A hammer plate is fixedly installed at the bottom of the hammer rod. When the hammer rod is no longer compressed, it can spring up from inside the support frame with the support of the second spring.

[0013] Preferably, the front end of the support rod is triangular in shape, and a support plate is fixedly installed on the surface of the support rod. When the front end of the support rod is pressed against, the support plate can be slid.

[0014] Preferably, the inner wall of the feed hopper body is rotatably connected to the surface of the circular plate, and a protrusion is fixedly installed on the surface of the circular plate. When the circular plate rotates inside the feed hopper body, the protrusion can rotate synchronously.

[0015] Preferably, the surface of the circular plate is fixedly connected to one end of the rotating rod, and the other end of the rotating rod is fixedly installed on the surface of the crushing roller. When the crushing roller rotates, the circular plate can be driven to make circumferential motion on the inner wall of the feed hopper body through the rotating rod.

[0016] Compared with the prior art, this utility model provides an anti-clogging feed hopper structure for mining machinery, which has the following beneficial effects:

[0017] 1. The anti-clogging feed hopper structure of this mining machinery is equipped with a control component. When the output shaft of the motor drives the crushing rollers to rotate, the two sets of crushing rollers can perform preliminary crushing on the incoming coal blocks. At the same time, when the crushing rollers rotate, the rotating rods fixed on the surface of the crushing rollers can drive the circular plate to perform synchronous circumferential motion within the feed hopper body. When the circular plate rotates, the protrusions fixed on the surface of the circular plate will abut against the tangential surface of the support rod. When the tangential surface of the support rod is abutted, the support rod can move downwards, and the movable rod hinged to the surface of the support rod can be folded, pushing the slider and the lever to continuously move on the surface of the screen plate, thereby enabling the crushed coal blocks to pass through the screen plate quickly and avoiding clogging of the feed hopper body.

[0018] 2. The anti-clogging feed hopper structure of this mining machinery is equipped with anti-clogging components. During the longitudinal movement of the support rod, the support plate fixed to the surface of the support rod will abut against the surface of the hammer rod. When the hammer rod is under force, it can move longitudinally within the support frame and intermittently knock on the surface of the screen plate through the hammer plate, thereby accelerating the passing efficiency of coal blocks.

Detailed Implementation

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a non-clogging feed hopper structure for mining machinery, including a feed hopper body 1, a motor 2 fixedly mounted on the surface of the feed hopper body 1, the output shaft of the motor 2 fixedly connected to the surface of a crushing roller 3, the crushing roller 3 rotatably connected to the inner wall of the feed hopper body 1, a screen plate 4 fixedly mounted on the inner wall of the feed hopper body 1, a support frame 5 fixedly mounted on the inner wall of the feed hopper body 1, and a control component 6 provided inside the feed hopper body 1, the control component 6 including: a lever 61 The components include slider 62, movable rod 63, support rod 64, and anti-blocking component 65. When the circular plate 657 rotates, the protrusion 658 fixed on the surface of the circular plate 657 will abut against the tangential surface of the support rod 64. When the tangential surface of the support rod 64 is abutted, the support rod 64 can move downwards, and the movable rod 63 hinged to the surface of the support rod 64 can be folded, pushing slider 62 and lever 61 to continuously move on the surface of screen plate 4, so that the crushed coal blocks can quickly pass through screen plate 4 and avoid clogging of the feed hopper body 1.

[0025] A lever 61 is fixedly mounted on the surface of a slider 62. The slider 62 is slidably connected to the inner wall of the support frame 5. The surface of the slider 62 is hinged to one end of a movable rod 63, and the other end of the movable rod 63 is hinged to the surface of a support rod 64. When the support rod 64 moves longitudinally, the movable rod 63 can be folded, pushing the slider 62 to slide. The anti-blocking component 65 includes a fixed rod 651, which is fixedly mounted on the surface of the support frame 5. The fixed rod 651 passes through the support rod 64 and is slidably connected to the support rod 64. The surface of the support rod 64 is fixedly connected to one end of a spring 652, and the other end of the spring 652 is fixedly mounted on the surface of the fixed rod 651. When the support rod 64 is no longer resisted, it can spring up from the surface of the fixed rod 651 under the support of the spring 652. The support frame 5 is penetrated by and slidably connected to the striking rod 654. The surface of the striking rod 654 is fixedly connected to one end of the second spring 655, and the other end of the second spring 655 is fixedly installed on the surface of the support frame 5. A striking plate 656 is fixedly installed at the bottom of the striking rod 654. When the striking rod 654 is no longer compressed, it can spring up from inside the support frame 5 with the support of the second spring 655. The front end of the support rod 64 is triangular in shape, and a support plate 653 is fixedly installed on the surface of the support rod 64. When the front end of the support rod 64 is pressed, it can drive the support plate 653 to slide. The inner wall of the feed hopper body 1 is rotatably connected to the surface of the circular plate 657. A protrusion 658 is fixedly installed on the surface of the circular plate 657. When the circular plate 657 rotates inside the feed hopper body 1, the protrusion 658 can rotate synchronously. The surface of the circular plate 657 is fixedly connected to one end of the rotating rod 659, and the other end of the rotating rod 659 is fixedly installed on the surface of the crushing roller 3. When the crushing roller 3 rotates, the circular plate 657 can be driven to make circular motion on the inner wall of the feed hopper body 1 through the rotating rod 659.

[0026] In this invention, during use, coal blocks are conveyed into the feed hopper body 1 using a conveying structure. During this process, the motor 2 on the surface of the feed hopper body 1 is activated. The output shaft of the motor 2 drives the crushing rollers 3 to rotate. As the two sets of crushing rollers 3 rotate, the coal blocks are initially crushed. The crushed coal blocks fall onto the surface of the screen plate 4. During the rotation of the crushing rollers 3, the rotating rod 659 fixed to the surface of the crushing rollers 3 drives the circular plate 657 to synchronously rotate within the feed hopper body 1. When the circular plate 657 rotates, the protrusion 658 fixed to the surface of the circular plate 657 will abut against the tangential surface of the support rod 64. When the tangential surface of the support rod 64 is abutted, the support... The rod 64 can move downwards, and the movable rod 63 hinged to the surface of the support rod 64 can be folded, pushing the slider 62 and the lever 61 to continuously move on the surface of the screen plate 4, so that the crushed coal blocks can pass through the screen plate 4 quickly and avoid clogging of the feed hopper body 1. During the longitudinal movement of the support rod 64, the support plate 653 fixed to the surface of the support rod 64 will abut against the surface of the knocking rod 654. When the knocking rod 654 is under force, it can move longitudinally within the support frame 5 and intermittently knock on the surface of the screen plate 4 through the knocking plate 656, thereby accelerating the passing efficiency of the coal blocks. After the coal blocks pass through the screen plate 4, they can enter the subsequent processing equipment for further operations.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
