Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically to an automated control device for mining machinery. Background Technology

[0002] In a broad sense, prospecting machinery also belongs to mining machinery. In addition, a large number of cranes, conveyors, ventilators and drainage machinery are used in mining operations. With the development and progress of society, the demand for fine crushing and collection devices for mining machinery is becoming increasingly strong. How to improve the screening efficiency of fine crushed stone is an urgent problem to be solved.

[0003] A search revealed that CN221907602U discloses an automated control device for mining machinery, including a feed inlet, a processing chamber, and support legs installed at the four corners of the lower surface of the processing chamber. A crushing chamber is located above the interior of the processing chamber. A drive motor is installed on one side of the outer surface of the processing chamber, and a reciprocating screw is fixedly connected to the output end of the drive motor, rotating relative to the interior of the processing chamber. A screening box is installed in the middle of the interior of the processing chamber. The drive motor output drives the reciprocating screw to rotate, allowing the sleeve block to move and engage with the push plate inside the screening box. This, combined with the U-shaped frame, allows the push plate below to move synchronously inside the collection box. Consequently, stones in the screening box and collection box are automatically and directly discharged from the guide plate and guide chute to the outside for collection, effectively saving operator steps and improving the automation level of the device.

[0004] The problem with the aforementioned automated control device for mining machinery is that:

[0005] 1. Lack of dynamic stirring mechanism during screening process

[0006] The comparison paper relies on the linear movement of the pusher plate and the U-shaped frame to push the stones out, but it does not solve the problem of screen clogging caused by the accumulation of stones due to gravity during the screening process. Static or unidirectional pushing screening methods easily cause fine particles to form an accumulation layer on the screen plate, reducing screening efficiency and effective utilization of the screen.

[0007] II. Multiple drive components lead to structural complexity

[0008] The comparative document uses a multi-component linkage of drive motor, reciprocating screw, and sleeve block to achieve screening and collection, requiring an independent drive to move the push plate within the screening and collection boxes. This design necessitates an additional power transmission mechanism, increasing mechanical complexity, and the reciprocating screw is prone to wear, resulting in higher maintenance costs. Utility Model Content

[0009] This utility model proposes an automated control device for mining machinery, which solves the problems of lack of dynamic stirring mechanism and complex structure caused by multiple driving components in the screening process in the prior art.

[0012] Preferably, the flipping assembly includes a motor, which is fixedly mounted on the upper part of the bracket.

The turning assembly also includes turning plates, which are three sets arranged in a ring and fixedly connected to the outside of the main rotating shaft.

[0015] Preferably, the linkage component further includes a second synchronous wheel, which is rotatably connected to the back of the screening cylinder, and the second synchronous wheel is fixedly connected to the top column.

[0016] Preferably, the linkage component further includes a timing belt, which is sleeved on the outside of the first timing pulley and the second timing pulley, and the timing belt is meshed with the first timing pulley and the second timing pulley for transmission.

[0017] Preferably, the vibrating screen assembly includes a screen mesh, which is fixedly connected to the middle of the screen plate.

[0018] Preferably, the vibrating screen assembly further includes a sliding sleeve, which is symmetrically arranged at the bottom of the screening cylinder. One end of the sliding sleeve is fixedly connected to the screening cylinder, and the other end of the sliding sleeve is slidably connected to the screen plate. The vibrating screen assembly also includes a spring ring, which is sleeved on the outside of the sliding sleeve and located below the screen plate.

[0019] Preferably, the vibrating screen assembly further includes a U-shaped connecting rod, one end of which is fixedly connected to the screen plate, and the other end of which is slidably connected to a limiting rod, which is fixedly connected to a groove on the back of the screening cylinder. The beneficial effects of this utility model are:

[0020] I. Synergistic Design of Dynamic Tumbling and Vibrating Screening

[0021] Improvement: Add a linkage mechanism between the flipping assembly (main rotating shaft + annular flipping plate) and the vibrating screen assembly (top column + screen plate).

[0022] Advantages: The continuously rotating flipping plate breaks up the pile of stones, allowing fine particles to fully contact the screen; the vibrating screen assembly periodically lifts the screen plate through the top column, and with the spring ring elastically resetting, it achieves high-frequency vibrating screening.

[0023] Comparison Results: This solution resolves the clogging issue caused by static screening of comparison files, improving screening efficiency.

[0024] II. Synchronous Linkage Structure of Single-Motor Drive

[0025] Improvement: The tumbling assembly and the vibrating screen assembly are mechanically coupled through a synchronous pulley and synchronous belt, requiring only a single motor drive.

[0026] Advantages: The rotation of the flipping plate and the vibration of the screen plate are driven by the same power source, reducing redundant drive components; the synchronous belt meshing transmission has high stability and avoids the wear problem of the reciprocating screw in the comparison document.

[0027] Comparison of results: Simplified mechanical structure, reduced energy consumption and maintenance costs, and improved system reliability. Attached Figure Description

[0035] Please see Figure 1 and Figure 2 and Figure 3 and Figure 4 This utility model provides a technical solution: an automated control device for mining machinery, including a screening cylinder 1, a turning component 2 for turning stones inside the screening cylinder 1 in the middle, a vibrating screen component 4 at the bottom of the screening cylinder 1, the vibrating screen component 4 including a top column 41 and a screen plate 43 for vibrating and screening stones as the top column 41 rotates, and a linkage component 3 for keeping the turning component 2 and the vibrating screen component 4 working synchronously is provided at the connection between them;

[0036] This design achieves a dual breakthrough in screening efficiency and mechanical reliability through two major improvements: coordinated tumbling and vibration actions and simplified mechanical linkage. It effectively overcomes the problems of incomplete screening and complex structure in existing technologies.

[0037] Please see Figure 1 The top slot of the screening cylinder 1 is fixedly connected to the feed port 11, the front of the screening cylinder 1 is fastened with the observation plate 12, and the back of the screening cylinder 1 is fixedly connected with the bracket 13.

[0038] Stones to be screened can be added into the screening cylinder 1 through the feed inlet 11;

[0039] The current screening situation inside the screening cylinder 1 can be observed through the observation plate 12, and the motor 21 can be supported and installed through the bracket 13.

[0040] Please see Figure 2 The flipping component 2 includes a motor 21, which is fixedly mounted on the upper part of the bracket 13.

[0041] Please see Figure 2 and Figure 3 and Figure 4 The linkage component 3 includes a first synchronous pulley 31, which is fixedly connected to the output end of the motor 21;

[0042] The flipping assembly 2 also includes a main rotating shaft 22, which is rotatably connected to the inside of the screening cylinder 1, and one end of the main rotating shaft 22 is fixedly connected to the first synchronous wheel 31. The flipping assembly 2 also includes a flipping plate 221, which is three sets arranged in a ring and fixedly connected to the outside of the main rotating shaft 22.

[0043] The linkage component 3 also includes a second synchronous wheel 32, which is rotatably connected to the back of the screening cylinder 1, and the second synchronous wheel 32 is fixedly connected to the top column 41;

[0044] The linkage assembly 3 also includes a timing belt 33, which is sleeved on the outside of the first timing pulley 31 and the second timing pulley 32. The timing belt 33 is meshed with the first timing pulley 31 and the second timing pulley 32.

[0045] The vibrating screen assembly 4 includes a screen 431, which is fixedly connected to the middle of the screen plate 43;

[0046] The vibrating screen assembly 4 also includes a sliding sleeve 44, which is symmetrically arranged at the bottom of the screening cylinder 1.

The vibrating screen assembly 4 also includes a spring ring 441, which is sleeved on the outside of the sliding sleeve 44 and located below the screen plate 43.

Under the elastic action of the spring ring 441, the screen plate 43 and the screen mesh 431 can reciprocate vertically in the lower part of the screening cylinder 1. At the same time, during the oscillation, the main rotating shaft 22 will continuously turn over the stones in the screening cylinder 1 to avoid accumulation.

[0049] Working principle:

[0050] The staff first put the stones to be screened into the screening cylinder 1 through the feed inlet 11, and then started the motor 21, so that the output end of the motor 21 drives the main shaft 22 and the flipping plate 221 to flip inside the screening cylinder 1 through the first synchronous wheel 31.

[0051] At the same time, when the first synchronous pulley 31 rotates and the second synchronous pulley 32 and the synchronous belt 33 mesh and drive, the synchronous belt 33 will drive the top column 41 to rotate synchronously and reciprocate to press down the U-shaped connecting rod 42. At this time, the screen plate 43 will reciprocate vertically under the elastic action of the spring ring 441. This design, together with the flipping plate 221, can prevent stones from accumulating on the upper part of the screen plate 43, thereby effectively improving the screening efficiency of stones.
