Description

Technical Field

[0001] This invention relates to the field of conveying technology, and in particular to a magnetorheological waveguide adaptive energy-saving conveyor belt. Background Technology

[0002] Traditional conveyor belts generally suffer from unstable operation, high energy consumption, and poor adaptability during material transport. With the development of industrial automation, higher requirements have been placed on the stability, energy efficiency, and adaptability of conveyor belts. Magnetorheological technology, as an emerging intelligent material technology, has shown good application prospects in fields such as vibration reduction and braking, but its application in the field of conveyor belts is still in the exploratory stage.

[0003] In material conveying scenarios in industries such as mining, ports, and building materials, uneven loads are common. When the load is uneven, the tension of different sections of the belt is inconsistent, with high tension in the heavy-load area and low tension in the light-load area. This tension difference propagates along the belt in the form of waves and is repeatedly reflected and superimposed between the slack and tight sides, generating periodic impacts and equivalent eccentric excitation forces. These excitation sources combined together manifest as vibration. When in use, materials need to be conveyed to designated locations for packaging.

[0004] For example, the patent application "CN213322119U" entitled "A Magnetic Suspension Energy-Saving Conveyor Belt" mainly introduces a magnetic rubber layer on top of the lower cover rubber. The conveyor belt and the magnetized idler rollers of the conveyor generate a repulsive force, overcoming the indentation resistance of the conveyor belt and idler rollers, and reducing periodic impacts and equivalent eccentric excitation forces. Although this reduces vibration, it requires power to be supplied to the electromagnets inside the magnetized idler rollers. When the local load is large, the load-bearing magnetized idler rollers need to be energized during the conveying process, resulting in unnecessary energy consumption. Therefore, measures need to be taken to distribute the material more evenly on the conveyor belt. Existing technologies can use scraping methods to distribute the material evenly to reduce weight differences in various locations. However, in the mining field, further measures are needed. When conveying crushed stone and sand materials, the ratio of crushed stone to crushed sand is not constant. The main component of crushed sand is silicon dioxide. The particle density of pure quartz sand is close to that of crushed stone. However, crushed sand particles are usually formed by long-term weathering and abrasion. The particles may have slight internal pores, and their density is slightly lower than that of dense rock. Crushed sand particles are mostly spherical or near-spherical, and the contact between particles is mainly point contact. When piled up, the gaps between particles are larger, resulting in a significantly higher porosity than crushed stone. The bulk density of crushed stone is generally higher than that of crushed sand. Therefore, under the same bulk volume, the total mass of crushed stone is greater, and the gravity it experiences is also greater. So even if the bulk volume is constant at all points on the conveyor belt, it will still lead to uneven gravity on all points on the conveyor belt, which can easily cause conveying vibration. Summary of the Invention

[0005] The purpose of this invention is to provide a magnetorheological waveguide adaptive energy-saving conveyor belt that can separate and mix crushed sand and gravel with the same volume but different gravity in a certain proportion, ensuring that the proportion of crushed sand and gravel is constant each time it is discharged. This can improve the uniformity of the gravity of the discharged material each time, thereby reducing the uneven gravity on the conveyor belt and further reducing conveying vibration, thus solving the problems mentioned in the background art.

The drive assembly also includes a baffle fixedly connected inside the unloading frame, and the top of the push plate is slidably connected inside the baffle.

[0010] Preferably, a temporary storage cavity is provided at the bottom of the sand collecting frame, and the even distribution component includes a baffle plate slidably connected to the top and bottom of the temporary storage cavity of the sand collecting frame. A rack frame is arranged on the right side of the baffle plate. The even distribution component also includes a rotating shaft rotatably connected inside the dropping frame. A torsion spring is fixedly connected between the rotating shaft and the dropping frame. Gears are fixedly connected to the outer side of the rotating shaft at the positions corresponding to the two rack frames. The outer sides of the two gears mesh with the corresponding rack frames.

[0011] Preferably, the inside and front side of the unloading frame are provided with a transmission assembly for driving the rack frame to move. The transmission assembly includes a transmission rod fixedly connected to the front side of the cylinder, the end of the transmission rod passing through the front side of the unloading frame and rotatably connected to the unloading frame. The transmission assembly also includes a round shaft rotatably connected to the front of the unloading frame, a cam fixedly connected to the rear end of the round shaft, and a blocking block fixedly connected to the rack frame above.

[0012] Preferably, both the end of the transmission rod and the end of the round shaft are fixedly connected to sprockets, and the two sprockets are connected by a chain drive.

This can improve the weight of the material discharged each time, thereby reducing the uneven weight distribution on the conveyor belt and further reducing conveying vibration. 2. By ensuring a consistent amount of crushed sand discharged each time, the ratio between crushed sand and crushed stone discharged each time is kept constant, and the total amount of crushed sand and crushed stone discharged each time is also consistent. This design helps to ensure that the amount of material discharged each time is consistent, further reducing uneven gravity on the conveyor belt and thus further reducing conveying vibration. 3. When crushed stone and sand fall into the inlet, the impact force of the crushed stone is reduced under the elastic force of the second spring. Then the crushed stone falls from the bottom of the discharge frame onto the conveyor belt. This design can reduce the impact of the material falling onto the conveyor belt, thereby further reducing the vibration of the falling material. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: Please refer to Figures 1 to 12 The present invention provides a technical solution: a magnetorheological waveguide adaptive energy-saving conveyor belt, including a frame 1, a rubber belt 2 connected to the frame 1, and a soft magnetic reinforcement layer 21, a skeleton layer 22 and a magnetic rubber layer 23 arranged sequentially from top to bottom inside the rubber belt 2. An electromagnetic component 3 is arranged inside the frame 1. The present invention introduces a soft magnetic reinforcement layer 21 to guide and constrain the magnetic field of the magnetic rubber layer 23 and reduce diffusion to the non-working direction.

[0022] By adopting the above technical solution, the electromagnetic component 3 includes a mounting plate fixedly connected to the inside of the frame 1. Electromagnets are mounted in a linear array on the mounting plate. Electromagnets are a mature existing technology and will not be described in detail. Sensors are distributed below the belt or at key load-bearing nodes. When the belt carries materials such as gravel, local pressure acts on the sensors, causing the piezoelectric ceramic material inside to deform under pressure. The internal electric domains are oriented along the direction of force, and positive and negative charges corresponding to the magnitude and distribution of pressure are generated on the surface, completing the conversion of mechanical pressure into electrical signals. Thus, by setting a controller, the electromagnets at the larger load-bearing positions are energized, and a repulsive force is generated between the electromagnets and the magnetic rubber layer 23, which overcomes the indentation resistance of the conveyor belt, reduces the running resistance and friction coefficient of the conveyor belt, saves operating energy consumption, and reduces the generation of periodic impacts and equivalent eccentric excitation forces, thereby reducing vibration. This technology is a mature existing technology and will not be described in detail.

[0023] The energy-saving conveyor belt also includes a uniform distribution component 4 disposed on the top left side of the frame 1. The uniform distribution component 4 includes a material drop frame 41 fixedly connected to the top left side of the frame 1. A filter plate 42 is fixedly connected inside the material drop frame 41. The surface of the filter plate 42 has filter holes. A push plate 43 is slidably connected inside the frame 1 above the filter plate 42. A sand collection frame 44 is fixedly connected to the bottom of the filter plate 42. A stone collection frame 45 is fixedly connected inside the frame 1 below the filter plate 42. A cylinder 46 is rotatably connected inside the stone collection frame 45. A material drop port 47 is opened on the circumferential side of the cylinder 46. A material passage pipe 48 is fixedly inserted between the bottom of the sand collection frame 44 and the bottom of the stone collection frame 45. The uniform distribution component is disposed inside the sand collection frame 44 and on its right side. 5. A first motor 9 is fixedly connected to the rear side of the discharge rack 41. The output shaft end of the first motor 9 is fixedly connected to the cylinder 46. Baffle plates 49 are fixedly connected to both sides of the filter plate 42. The baffle plates 49 are made of elastic material. A drive assembly 6 for driving the push plate 43 to move in the left and right direction is arranged on the top of the discharge rack 41. The drive assembly 6 includes a second motor 61 fixedly connected to the right side of the discharge rack 41. A lead screw 62 is fixedly connected to the output shaft of the second motor 61. The end of the lead screw 62 is rotatably connected to the inner side of the discharge rack 41. The outer side of the lead screw 62 is threadedly connected to the push plate 43. The drive assembly 6 also includes a baffle cover 63 fixedly connected inside the discharge rack 41. The top of the push plate 43 is slidably connected inside the baffle cover 63.

[0024] By adopting the above technical solution, when in use, the crushed stone and sand to be conveyed enter from the top of the feed rack 41. Subsequently, the material falls onto the filter plate 42. Fine sand passes through the filter holes of the filter plate 42, allowing the sand to enter the interior of the sand collection rack 44. The filter plate 42 blocks larger crushed stone particles. The output shaft of the second motor 61 rotates, which causes the lead screw 62 to rotate, so that the push plate 43 moves in the left and right direction. This pushes the crushed stone so that it is discharged from both sides of the filter plate 42 and falls into the interior of the stone collection rack 45.

[0025] During the conveying process, the output shaft of the first motor 9 rotates continuously, causing the cylinder 46 to rotate continuously. When the discharge port 47 rotates to the top position, the material can enter the cylinder 46 through the discharge port 47 and fill the cylinder 46. As the cylinder 46 continues to rotate, the discharge port 47 rotates to the bottom position, at which point the crushed stone can fall. Since the internal volume of the cylinder 46 is fixed, the amount of crushed stone falling each time is constant. At this time, the uniform dropping component 5 at the sand collecting frame 44 evenly feeds crushed sand to the bottom of the stone collecting frame 45.

[0026] This design can separate crushed sand and gravel with the same volume but different weights and mix them in a certain proportion, ensuring that the ratio of crushed sand and gravel is constant each time they are discharged. This makes the weight of the discharged material more similar each time, thereby reducing uneven weight distribution on the conveyor belt and further reducing conveying vibration.

[0027] It should be noted that a scraper is installed inside the frame 1 above the rubber belt 2 to scrape the material falling evenly each time, further reducing the weight difference in different parts.

[0028] It should be noted that the second motor 61 is a three-phase motor, which can change the direction of rotation. By changing the direction of rotation of the second motor 61, the push plate 43 can reciprocate in the left and right direction. The baffle plate 49 is made of an elastic material. When the push plate 43 moves to the position of the baffle plate 49, the squeezing action of the push plate 43 makes the baffle plate 49 deflect, thereby facilitating the discharge of crushed stone. The inclined setting of the baffle plate 49 can reduce the discharge of crushed sand from both sides of the filter plate 42. It should be noted that there is a certain gap between the bottom of the push plate 43 and the filter plate 42. When the push plate 43 moves, it can agitate the crushed sand, which is conducive to the crushed sand passing through the filter holes of the filter plate 42.

[0029] A temporary storage cavity 10 is provided at the bottom of the sand collecting frame 44. The even distribution component 5 includes a baffle plate 51 slidably connected to the top and bottom of the temporary storage cavity 10 of the sand collecting frame 44. A rack frame 52 is arranged on the right side of the baffle plate 51. The even distribution component 5 also includes a rotating shaft 53 rotatably connected inside the discharge frame 41. A torsion spring 54 is fixedly connected between the rotating shaft 53 and the discharge frame 41. Gears 55 are fixedly connected to the outer side of the rotating shaft 53 at the positions corresponding to the two rack frames 52. The outer sides of the two gears 55 mesh with the corresponding rack frames 52. The inside and front side of the unloading rack 41 are equipped with a transmission assembly 7 for driving the rack frame 52. The transmission assembly 7 includes a transmission rod 71 fixedly connected to the front side of the cylinder 46. The end of the transmission rod 71 extends out from the front side of the unloading rack 41 and is rotatably connected to the unloading rack 41. The transmission assembly 7 also includes a round shaft 72 rotatably connected to the front of the unloading rack 41. A cam 73 is fixedly connected to the rear end of the round shaft 72. A blocking block 74 is fixedly connected to the rack frame 52 above. A sprocket 75 is fixedly connected to both the end of the transmission rod 71 and the end of the round shaft 72. The two sprockets 75 are connected by a chain 76.

[0030] It should be noted that when the upper baffle plate 51 blocks the sand collection rack 44 above the temporary storage chamber 10, the lower baffle plate 51 does not block the sand collection rack 44 below the temporary storage chamber 10.

[0031] By adopting the above technical solution, when the protruding part of the cam 73 is in a position away from the blocking block 74, under the elastic force of the torsion spring 54, the upper blocking plate 51 does not block the sand collection frame 44, while the lower blocking plate 51 blocks the sand collection frame 44. The broken sand that enters the sand collection frame 44 enters the interior of the temporary storage chamber 10, while the broken sand cannot enter the stone collection frame 45 due to the blocking effect of the lower blocking plate 51.

[0032] When the output shaft of the first motor 9 rotates the cylinder 46, the transmission rod 71 rotates. Under the transmission action between the sprocket 75 and the chain 76, the shaft 72 rotates the cam 73. When the convex side of the cam 73 rotates to a position close to the blocking block 74, the blocking block 74 moves the upper rack 52 to the left under the squeezing action of the cam 73. At this time, when the upper rack 52 moves with the upper blocking plate 51 to block the sand collection frame 44, the crushed sand can no longer fall down. When the upper rack 52 moves, the corresponding gear 55 rotates the rotating shaft 53 against the elastic force of the torsion spring 54, which makes the corresponding gear 55 of the lower rack 52 rotate. Thus, the lower rack 52 moves with the lower blocking plate 51 to the right and no longer blocks the lower position of the temporary storage cavity 10, making it easier for the crushed sand to enter the stone collection frame 45 and mix with the crushed stone.

[0033] It should be noted that when the discharge port 47 of the cylinder 46 is in the upper position, the protruding part of the cam 73 is in a position away from the blocking block 74. At this time, the lower blocking plate 51 blocks the lower position of the temporary storage cavity 10. When the discharge port 47 rotates to the lower position, the protruding part of the cam 73 squeezes the blocking block 74, and the lower blocking plate 51 does not block the lower position of the temporary storage cavity 10. The material is discharged. Since the internal capacity of the temporary storage cavity 10 is fixed, the amount of crushed sand discharged each time is fixed, which can make the ratio between crushed sand and crushed stone discharged each time fixed, and the total amount of crushed sand and crushed stone discharged each time is consistent. This design is conducive to the consistency of the amount of material discharged each time, further reducing the uneven gravity on the conveyor belt, thereby further reducing the vibration of the conveyor.

[0034] It should be noted that the baffle plate 51 is made of a rigid and relatively thin material.

[0035] The upper rack frame 52 is fixedly connected to the corresponding blocking plate 51, and the lower rack frame 52 is slidably connected to the corresponding blocking plate 51. The diameter of the gear 55 corresponding to the lower rack frame 52 is larger than the diameter of the gear 55 corresponding to the upper rack frame 52. A first spring 56 is fixedly connected between the lower rack frame 52 and the corresponding blocking plate 51.

[0036] By adopting the above technical solution, since the diameter of the gear 55 corresponding to the lower rack 52 is larger than the diameter of the gear 55 corresponding to the upper rack 52, the distance the lower rack 52 moves each time is greater than the distance the upper rack 52 moves. When the cam 73 moves away from the blocking block 74, under the elastic force of the torsion spring 54, the lower rack 52 moves to the left and the upper rack 52 moves to the right. After the lower rack 52, along with the lower blocking plate 51, completes the sealing, the lower rack 52 will continue to move a certain distance. At this time, the lower rack frame 52 slides against the lower baffle plate 51, and the first spring 56 is compressed until the baffle plate 51 no longer blocks the sand from entering the temporary storage chamber 10. When the cam 73 presses the baffle block 74, the two rack frames 52 move, and the lower baffle plate 51 will remain in the temporary storage chamber 10 for a period of time under the elastic force of the first spring 56. This design can reduce the uneven discharge of sand caused by the movement of the baffle plate 51, thereby further reducing the generation of periodic impacts and equivalent eccentric excitation forces, and reducing vibration.

[0037] A buffer assembly 8 is provided below the stone collection frame 45. The buffer assembly 8 includes a discharge frame 81 that is slidably connected to the bottom of the stone collection frame 45. A second spring 82 is fixedly connected between the discharge frame 81 and the stone collection frame 45. The bottom of the discharge frame 81 is narrowed. A baffle plate 83 is fixedly connected inside the discharge frame 81. The top of the baffle plate 83 is inclined. The bottom of the discharge frame 81 is close to the rubber belt 2, which can reduce the vibration of the falling material.

[0038] By adopting the above technical solution, when the crushed stone and sand fall into the interior of the discharge frame 81, they fall onto the baffle plate 83 and reach the bottom closing point of the discharge frame 81, which can block the crushed stone and sand. When the crushed stone and sand fall in, the impact force of the crushed stone is reduced under the elastic force of the second spring 82. Then the crushed stone falls from the bottom of the discharge frame 81 onto the conveyor belt. This design can reduce the impact of the material falling onto the conveyor belt, thereby further reducing the vibration of the falling material.

[0039] Working principle: By setting the controller to energize the electromagnet at the larger load-bearing part, the electromagnet and the magnetic rubber layer 23 generate a repulsive force, which overcomes the indentation resistance of the conveyor belt, reduces the running resistance and friction coefficient of the conveyor belt, saves operating energy consumption, and reduces the generation of periodic impacts and equivalent eccentric excitation forces, thereby reducing vibration.

[0040] During conveying, the output shaft of the first motor 9 rotates continuously, causing the cylinder 46 to rotate continuously. When the discharge port 47 rotates to the top position, the material can enter the cylinder 46 through the discharge port 47 and fill the cylinder 46. As the cylinder 46 continues to rotate, the discharge port 47 rotates to the bottom position, at which point the crushed stone can fall. Since the internal volume of the cylinder 46 is fixed, the amount of crushed stone falling each time is constant. At this time, the evenly discharging component 5 at the sand collecting frame 44 evenly feeds crushed sand to the bottom of the stone collecting frame 45, ensuring that the ratio of crushed sand and crushed stone is constant each time. This can improve the uniformity of the weight of the material discharged each time, thereby reducing the uneven weight distribution on the conveyor belt and further reducing conveying vibration.

[0041] When the output shaft of the first motor 9 rotates the cylinder 46, the transmission rod 71 rotates. Under the transmission action between the sprocket 75 and the chain 76, the shaft 72 rotates the cam 73. When the convex side of the cam 73 rotates to a position close to the blocking block 74, the blocking block 74 moves the upper rack 52 to the left under the squeezing action of the cam 73. At this time, when the upper rack 52 moves with the upper blocking plate 51 to block the sand collection frame 44, the crushed sand can no longer fall down. When the upper rack 52 moves, the corresponding gear 55 rotates the rotating shaft 53 against the elastic force of the torsion spring 54, which makes the corresponding gear 55 of the lower rack 52 rotate. Thus, the lower rack 52 moves with the lower blocking plate 51 to the right and no longer blocks the lower position of the temporary storage cavity 10, making it easier for the crushed sand to enter the stone collection frame 45 and mix with the crushed stone.

[0042] When the gravel and sand fall into the discharge frame 81, they fall onto the baffle plate 83 and reach the bottom of the discharge frame 81, which can block the gravel and sand. When the gravel and sand fall in, the impact force of the gravel is reduced by the elastic force of the second spring 82.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them.
