Description

Technical Field

[0001] The invention relates to the field of mica production and transportation, and in particular to a mica production conveyor with an anti-drop component. Background Art

[0002] Mica is a rock-forming mineral primarily composed of layered aluminosilicates of potassium, aluminum, magnesium, iron, and lithium. In ancient China, mica was known as "sky skin" or "ground gold," hence the name "Tianpi Mountain" for its mica production area in Inner Mongolia. Mica's unique crystal structure and physical and chemical properties have led to its widespread application in various fields. It is an important insulating material, commonly used in electrical and electronics, insulation materials, cosmetics, coatings, and new energy. Mica is also used in the manufacture of electrical equipment and other industrial products.

[0003] A mica conveyor is a device specifically designed for conveying bulk materials such as mica powder, including powders, small granules, and small blocks. It can convey materials in a combination of horizontal, inclined, and vertical directions, and is widely used in industries such as chemicals, minerals, feed, and building materials. The mica conveyor's operating principle is that when the material is conveyed by the transmission components, the material is pushed in the direction of motion by the conveyor belt, forming a stable material flow. When conveying vertically, the material particles in the tube are pushed upward by the chain, forming a continuous material flow, thereby conveying the mica. However, the existing mica production conveyor still has some inconveniences during use. For example, the mica will slide to both sides until it falls due to the vibration of the conveyor belt during operation, causing the mica to be scattered on both sides of the conveyor, resulting in mica material loss and increased workload for cleaning the production site. At the same time, the conveyor can only transport mica materials in a single reverse direction during use, but cannot transport mica back and forth, resulting in long-term transportation of mica materials in a single direction, which will cause the mica to accumulate too high and affect the normal transportation and processing of the mica. Therefore, the existing mica conveyor cannot meet people's usage needs during use. Summary of the Invention

[0022] The present invention provides cleaning shafts 111 on both sides of the conveyor belt 18. When the conveyor belt 18 is running, the cleaning shafts 111 can clean both sides of the upper surface of the conveyor belt 18 to prevent the mica from sliding onto the ground through both sides of the conveyor belt 18. In addition, the bottom of one end of the conveyor belt 18 can receive the mica conveyed by the conveyor belt 18. Therefore, under the reciprocating swing of the guide hopper 26, the received mica can be transported and discharged, so that the surface mica is concentrated and accumulated at a single location, or the mica is evenly discharged to the processing equipment, which facilitates the processing equipment to uniformly process the mica. The present invention provides a support component 3 at the bottom of the conveying component 1, so that the inclination angle of the conveying component 1 can be adjusted, thereby being able to adjust the discharge height of the mica according to needs, thereby expanding the use range of the conveyor. Moreover, when the first drive motor 12 is running, it can drive the conveyor belt 18 to convey the mica, and at the same time, it can drive the cleaning shaft 111 to provide anti-fall protection for both sides of the conveyor belt 18. Moreover, while the conveyor belt 18 is running, the reciprocating screw 17 is driven to rotate through the first transmission chain 15, so that the reciprocating screw 17 drives the guide hopper 26 to synchronously reciprocate and deflect, thereby realizing the reciprocating discharge of the mica. Therefore, when the conveyor is running, only a single drive source is needed, thereby saving energy consumption and reducing the difficulty of operation, thereby meeting people's use needs. The present invention can prevent the transported mica from falling through the coordinated operation of the transport component 1, the drainage component 2 and the support component 3, thereby preventing the mica from being scattered on the ground and lost, and avoiding increasing the cleaning effort of the site. In addition, the transported mica can be transported and discharged back and forth, thereby meeting people's usage needs. The limiting skeleton 19 of the present invention is rotatably connected to the limiting rotating shaft 38 through the limiting shaft hole 11, so that the limiting skeleton 19 can be deflected up and down on the upper surface of the support base 37. The limiting skeleton 19 is threadedly connected to the outer surface of the threaded rod 34 through the threaded sleeve 110, and can adjust the inclination angle of the limiting skeleton 19 when the threaded rod 34 rotates. The output transmission shaft 116 at the end of the limiting skeleton 19 is rotatably connected to the helical gear transmission shaft 114 through the first transmission sprocket 117 and the second transmission chain 115, so that when the output transmission shaft 116 rotates, the rotation of the helical gear transmission shaft 114 can be controlled, thereby playing a transmission role between the cleaning shaft 111 and the output transmission shaft 116.

[0023] The two ends of the helical gear transmission shaft 114 of the present invention are rotatably connected to the cleaning shaft 111 through the helical gears 113. Since the two ends of the helical gear transmission shaft 114 are symmetrically arranged, when the helical gear transmission shaft 114 rotates, it will drive the two sets of cleaning shafts 111 to rotate synchronously in opposite directions, so that the mica on both sides can be cleaned to the middle of the conveyor belt 18. The reciprocating sleeve 24 is slidably sleeved on the outer surface of the reciprocating screw 17, and can drive the reciprocating sleeve 24 to slide back and forth when the reciprocating screw 17 rotates.

[0024] The upper outer surface of the reciprocating sleeve 24 of the present invention is provided with a socket hole, so that the reciprocating sleeve 24 is slidably socketed on the outer surface of the limit rod 16 through the socket hole, thereby limiting the sliding of the reciprocating sleeve 24. The crescent block 23 is movably clamped on the outer surface of the reciprocating screw rod 17 inside the reciprocating sleeve 24, and can adjust the sliding direction of the reciprocating sleeve 24 when the reciprocating sleeve 24 slides to the end of the reciprocating screw rod 17, thereby controlling the reciprocating swing of the guide hopper 26.

[0025] The guide hopper 26 of the present invention is rotatably connected to the annular limit frame 14 through the limit swivel 25, so that the annular limit frame 14 can limit the rotation of the guide hopper 26, ensuring the stable reciprocating deflection of the guide hopper 26. The second drive motor 31 is rotatably connected to the threaded rod 34 through the transmission gear 32 at the bottom, thereby controlling the rotation of the two groups of threaded rods 34 and adjusting the inclination angle of the conveyor belt 18 at the same time. Rollers are set at the four corners of the bottom of the support base 37, which can facilitate the movement of the conveyor.

[0026] The working principle of the present invention is as follows: when conveying mica, the conveyor is first moved to the required position, and then the first drive motor 12 is started to rotate. The first drive motor 12 will drive the conveyor belt 18 to rotate synchronously through the output transmission shaft 116, and then discharge the mica to the upper surface of the conveyor belt 18, so that the conveyor belt 18 can transport the mica on the upper surface at a uniform speed. When the output transmission shaft 116 rotates, the helical gear transmission shaft 114 will be driven to rotate through the second transmission chain 115 and the first transmission sprocket 117. Since the helical teeth at both ends of the helical gear transmission shaft 114 are symmetrically arranged, the helical gear transmission shaft 114 will drive the cleaning shaft 111 meshed at both ends to rotate synchronously in the opposite direction. Therefore, when the mica on the upper surface of the conveyor belt 18 slides to both sides, the rotating cleaning shaft 111 will rotate. The shaft 111 will come into contact with the mica, thereby sweeping the mica toward the middle of the conveyor belt 18, preventing the mica from sliding and falling to both sides, and ensuring that the mica that falls on the upper surface of the conveyor belt 18 can be transported normally. After the mica reaches the high point at one end of the conveyor belt 18, it will continue to be transported and discharged into the guide hopper 26 below. As the conveyor belt 18 rotates, it will drive another set of output transmission shafts 116 at one end of the limiting frame 19 to rotate synchronously. Therefore, the other set of output transmission shafts 116 will drive the reciprocating screw 17 to rotate synchronously through the first transmission chain 15, and the rotating reciprocating screw 17 will drive the reciprocating sleeve 24 on the outer surface to slide. Since the crescent block 23 inside the reciprocating sleeve 24 is movably engaged with the thread on the outer surface of the reciprocating screw 17, when the crescent block 23 reaches After reaching one end of the reciprocating screw 17, it will deflect, causing the reciprocating sleeve 24 to slide in the opposite direction on the outer surface of the reciprocating screw 17. At the same time, as the reciprocating sleeve 24 slides back and forth, the guide hopper 26 will be driven to deflect synchronously through the limit sleeve 22 and the plug-in plate 21. When the guide hopper 26 deflects, the limit swivel 25 will slide inside the annular limit frame 14, thereby ensuring the stable deflection of the guide hopper 26. Therefore, the mica falling into the guide hopper 26 will be reciprocatingly deflected and transported to the bottom for processing, or stacked and stored, thereby ensuring that the mica is evenly processed or evenly stacked and stored, meeting people's usage needs, and when it is necessary to adjust the inclination angle of the limit frame 19, the second drive motor 31 can be controlled to rotate and operate , so that the second drive motor 31 drives the threaded rod 34 engaged at the bottom to rotate. Since the two sets of threaded rods 34 are rotatably connected through the second transmission sprocket 33 and the third transmission chain 35, when the threaded rod 34 rotates inside the threaded sleeve 110, it will drive the limiting frame 19 to deflect with the limiting shaft hole 11 as the axis. At the same time, the threaded rod 34 will drive the limiting shaft block 39 at the bottom to deflect until the limiting frame 19 drives the conveyor belt 18 to deflect to a suitable angle. Therefore, through the coordinated operation between the conveying component 1, the guiding component 2 and the supporting component 3, the conveyed mica can be prevented from falling, thereby preventing the mica from being scattered on the ground and lost, and avoiding increasing the cleaning effort on the site, and the conveyed mica can be transported and discharged back and forth.So as to meet people's usage needs.
