Description

Technical Field

[0001] This utility model relates to the field of dry ore beneficiation, specifically to a guide plate structure for an intelligent dry separator. Background Technology

[0002] Dry ore sorting technology is an important branch of mineral processing. It separates ores by utilizing differences in their physical properties under anhydrous conditions, offering significant advantages such as environmental friendliness, energy efficiency, and low operating costs. In this technology, the intelligent dry separator is one of the core pieces of equipment. It uses an identification system to determine ore quality and drives the actuator to separate the target ore from the material flow. The guide plate structure, as a key component of the actuator, directly determines the overall sorting efficiency and effectiveness of the machine through its accuracy, reliability, and adaptability to different working conditions.

[0003] In existing technologies, the guide plate structure of intelligent dry separators mostly adopts a rigid flipping or integral lifting design. Specifically, a common solution is to directly drive the entire guide plate or a group of guide plates using a cylinder or hydraulic cylinder, causing it to rotate and lift around a fixed axis. When the control system issues a command, the drive component actuates, causing the guide plate to quickly lift up to intercept and deflect the target ore; conversely, it keeps the guide plate horizontal or lowers it, allowing non-target ore or waste rock to pass smoothly. This design structure is relatively simple and direct, and can meet basic sorting requirements in certain application scenarios.

[0004] The aforementioned existing technologies have significant limitations. Their function is singular, unable to pre-differentiate materials falling onto the guide plate. When encountering situations where ore sizes are mixed (i.e., ores of varying sizes enter the sorting area simultaneously), the guide plate, operating as a whole, cannot provide differentiated responses. This "one-size-fits-all" approach easily leads to decreased sorting accuracy under complex material conditions, affecting the quality of the final product. Therefore, there is an urgent need for a guide plate structure that can intelligently adapt to different ore sizes, combining pre-screening with stable sorting, to improve the overall performance and application range of dry separators. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an intelligent dry separator guide plate structure to solve the technical problem in the prior art that the sorting accuracy is easily reduced under complex material conditions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a guide plate structure for an intelligent dry separator.

[0007] Includes a housing, a first rotating shaft and a second rotating shaft fixed to the housing; Several rotating support rods are rotatably connected to the first rotating shaft; Each of the said rotating support rods is connected to a seesaw via a fixed limiting connecting block on its lower arm and a first spring support. One end of the seesaw is movably connected to one end of the first guide plate via a second rotating connecting block, and the other end is movably connected to the middle of the second guide plate via the first rotating connecting block. The seesaw is also connected to the first guide plate via a second spring, and to the second guide plate via a third spring and a fourth spring; The fulcrum of the seesaw is rotatably connected to one end of the first support arm, the other end of the first support arm is rotatably connected to one end of the second support arm, and the middle part of the second support arm is rotatably connected to the second rotation axis. A support block is movably connected to the end of the second support arm away from the first support arm, and the support block is fixed to the end of the pneumatic rod.

[0008] The present invention is further configured such that the ends of the first guide plate and the second guide plate are in contact with each other and rely on each other; the second guide plate extends from one end of the contact surface toward the seesaw direction to form a frame, such that when the contact surface end of the first guide plate is pressed down and rotates around the second rotating connecting block, its upper surface after being pressed down is not lower than the bottom surface of the second guide plate.

[0009] The present invention is further configured such that the second support arm is a right-angled structure, and its corner is rotatably connected to the second rotating shaft.

[0010] The present invention is further configured such that the support block is provided with a rotating shaft, and the end of the second support arm away from the first support arm is provided with an elongated groove for the rotating shaft of the support block to slide, so that when the pneumatic rod pushes and pulls the support block to move, it can drive the second support arm to rotate around the second rotating shaft.

[0011] The present invention is further configured such that the second spring is a replaceable spring with a predetermined elastic force specification, and when the pressure on the first guide plate at the connection end of the second spring exceeds its elastic force, the end can be pressed down by a corresponding distance.

[0012] In summary, the present invention has the following main advantages: This invention, through the coordinated structure of a seesaw, a multi-spring adjustment mechanism, and a pneumatic linkage mechanism, not only enables the rapid overall lifting and lowering of the guide plate via a pneumatic rod for efficient ore sorting, but also allows the first guide plate to sense and respond to the weight of the ore using an adjustable second spring. This enables intelligent pre-screening and deceleration of ores of different specifications, effectively eliminating interference from complex material conditions and fundamentally improving sorting accuracy and efficiency, while significantly reducing the risk of jamming and equipment impact wear.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] The embodiments of this utility model will be described below based on its overall structure.

[0017] This utility model provides a guide plate structure for an intelligent dry separator, such as... Figures 1 to 3 As shown, its core lies in achieving intelligent pre-screening and rapid sorting of ores through a sophisticated linkage structure.

[0018] The structure includes a housing 1 serving as the mounting base. A first rotating shaft 4 and a second rotating shaft 15 are fixedly mounted on the housing 1. A plurality of axially arranged rotating support rods 2 are rotatably connected to the first rotating shaft 4, and these rotating support rods 2 constitute the suspension base of the entire actuation module.

[0019] Each of the rotating support rods 2 has a limiting connecting block 7 fixed to its lower arm. Each limiting connecting block 7 is supported and connected to a seesaw 3 by a first spring 8. Specifically, the limiting connecting block 7 has an annular groove centered on the fulcrum of the seesaw 3, and the seesaw 3 has a protrusion at a corresponding position that mates with the annular groove. This mating structure of the annular groove and the protrusion allows the seesaw 3 to make stable, minute rotations around its fulcrum within the range limited by the annular groove, without detaching from the limiting connecting block 7, thus ensuring the reliability of the structure.

[0020] One end of the seesaw 3 (i.e., the end closer to the first rotating shaft 4) is movably connected to one end of the first guide plate 5 via a second rotating connecting block 18. The other end of the seesaw 3 (i.e., the end farther from the first rotating shaft 4) is movably connected to the middle of the second guide plate 6 via a first rotating connecting block 12. The first guide plate 5 and the second guide plate 6 are approximately parallel to the seesaw 3 in the initial state.

[0021] To provide the guide plate with dynamic response capability, the seesaw 3 is also connected to the first guide plate 5 via a second spring 9, and to the second guide plate 6 via a third spring 10 and a fourth spring 11. Specifically, the second spring 9 is a replaceable spring with a predetermined spring force specification. This means that the second spring 9 can be replaced with one of different spring coefficients according to the actual weight requirements of the ore to be sorted. When the pressure on the first guide plate 5 at the connection end of the second spring 9 (such as being hit by a large ore) exceeds its spring force, that end can be pressed down a corresponding distance, thereby achieving a pre-screening function based on weight perception.

[0022] To ensure a smooth transition between the first guide plate 5 and the second guide plate 6 when the first guide plate 5 is pressed down, the ends of the first guide plate 5 and the second guide plate 6 contact and rely on each other. Furthermore, the second guide plate 6 extends from one end of its contact surface towards the seesaw 3 to form a frame. This frame structure design ensures that when the contact surface end of the first guide plate 5 is pressed down and rotates around the second rotating connecting block 18, its pressed upper surface is never lower than the bottom surface of the second guide plate 6, thereby effectively preventing ore from getting stuck at the joint.

[0023] The fulcrum of the seesaw 3 is rotatably connected to one end of the first support arm 13. The other end of the first support arm 13 is rotatably connected to one end of the second support arm 14. The middle part of the second support arm 14 is rotatably connected to the second rotating shaft 15. In this embodiment, the second support arm 14 has a right-angled structure (i.e., L-shaped), and its corner is rotatably connected to the second rotating shaft 15. This structure can effectively convert the linear motion of the pneumatic rod 17 into the rotational motion of the support arm.

[0024] A support block 16 is movably connected to the end of the second support arm 14 away from the first support arm 13. Specifically, the support block 16 is provided with a rotating shaft, and the end of the second support arm 14 has an elongated groove for the rotating shaft of the support block 16 to slide. The support block 16 is ultimately fixed to the end of the pneumatic rod 17. This sliding pair structure of the elongated groove and the rotating shaft allows the second support arm 14 to smoothly rotate around the second rotating shaft 15 when the pneumatic rod 17 pushes or pulls the support block 16 to move linearly.

[0025] Working principle: This utility model has two core working modes during operation: Overall rapid sorting mode: The pneumatic rod 17 extends and retracts according to the instructions issued by the intelligent recognition system. When it is necessary to eject the target ore, the pneumatic rod 17 extends, pushing the support block 16 outward. The support block 16 slides in the long groove of the second support arm 14 through its rotation axis, and pulls the second support arm 14 to rotate around the second rotation axis 15. The rotation of the second support arm 14 pushes the first support arm 13, thereby supporting the whole consisting of the seesaw 3, the rotating support rod 2, the first guide plate 5, the second guide plate 6 and all connecting structures, so that it rotates and rises rapidly around the first rotation axis 4, thereby ejecting the target ore located on it and achieving sorting. When it is necessary to allow the ore to pass, the pneumatic rod 17 shortens, and through the above-mentioned linkage mechanism, reverses its action, finally pulling the entire guide plate structure to quickly descend around the first rotation axis 4, restoring it to the state where the ore can pass normally.

[0026] Intelligent pre-screening and buffering mode: This mode is activated when mixed ores (i.e., ores of different sizes) fall simultaneously onto the guide plate. For small ores smaller than the preset elastic force of the second spring 9, their impact on the first guide plate 5 is insufficient to overcome the elastic force of the second spring 9. Therefore, the end of the first guide plate 5 located on the second spring 9 will not press down, allowing the small ores to slide normally through the first guide plate 5. For large ores larger than the preset elastic force of the second spring 9, their impact on the first guide plate 5 will overcome the elastic force of the second spring 9, forcing that end of the first guide plate 5 to press down. The pressing end of the first guide plate 5 will momentarily jam or rub against the side of the extended frame of the second guide plate 6, thereby slowing down and hindering the large ores. At the same time, small ores behind can pass over or to the side of the large ores, or impact the large ores, causing them to change trajectory and fly towards other guide plates, thus resolving the situation of "complex materials" coexisting and creating conditions for the precise sorting performed by the subsequent pneumatic rod 17.

[0027] The ingenuity of this invention lies in the fact that it is not a simple "baffle," but an intelligent mechanical system integrating "sensing" and "execution." Its core mechanism resembles a precise "seesaw" structure: when ores of varying sizes fall, the lighter, smaller ores cannot press down on the "first guide plate" supported by a specific spring and pass smoothly; while the heavier, larger ores press down on one end of the guide plate, triggering a brief jamming effect, acting like an intelligent screen to instantly separate and sort the mixed materials by weight. Subsequently, the drive mechanism moves as a whole, like a strong "arm," precisely launching the target ores to be sorted according to instructions. This collaborative working mechanism of "intelligently sensing and sorting the situation first, then precisely applying force" fundamentally solves the shortcomings of traditional structures that "cut off" complex materials, achieving efficient, accurate, and reliable sorting.

[0028] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
