Description

Technical Field

[0001] The present application relates to the technical field of transmission equipment, and in particular to a swing belt conveyor. Background Art

[0002] Belt conveyor is the abbreviation of belt conveyor, which has fixed and mobile types, simple structure and high efficiency. It is a continuous conveying machine that uses flexible conveyor belt as material carrying and traction component.

[0003] Among them, the swing belt conveyor is a special structure conveyor in the belt conveyor.

[0004] The swing of the swing belt conveyor is generally achieved through chain drive, gear rack drive, or synchronous belt and synchronous wheel drive. This transmission method is generally achieved through the forward and reverse rotation of the motor. However, in practical use, the sprocket chain and gear rack are easy to pollute the production environment of the factory under open lubrication conditions, and the materials splashed during the production process in the processing plant are easy to get stuck in the chain sprocket and gear rack, increasing the risk of downtime and high cost. Although the synchronous belt does not need lubrication, it is troublesome to replace, and the matching synchronous wheel must be made, which increases the cost. In addition, it is difficult to avoid the inertial rotation and time difference of the motor during the forward and reverse rotation of the drive motor, which not only has a complex structure, but also affects production efficiency. Summary of the invention

[0005] In order to reduce the accident rate of equipment and improve the stability of the swing belt conveyor, the present application provides a swing belt conveyor.

[0006] The present application provides a swing belt conveyor adopting the following technical solution:

[0007] A swing-head belt conveyor comprises a belt conveyor body, a slewing bearing is provided below the belt conveyor body, one end of the transmission starting point of the belt conveyor body is installed on the slewing bearing, a support platform is provided below the belt conveyor body, the belt conveyor body is slidably connected to the support platform, a driving motor is provided on one side of the belt conveyor body, the driving motor is located between the support platform and the slewing bearing, the axis of the output shaft of the driving motor is parallel to the axis of the slewing bearing, a rotating disk is fixedly connected to the end of the output shaft of the driving motor, the rotating disk is coaxially arranged with the output shaft of the driving motor, a crank rocker is provided between the rotating disk and the belt body of the belt conveyor body, one end of the crank rocker is rotatably connected to the edge of the rotating disk, and the other end of the crank rocker is rotatably connected to the lower end of the belt conveyor body.

[0008] By adopting the above technical scheme, the driving motor can be started so that the output shaft of the driving motor drives the rotating disk to rotate, thereby driving the crank rocker to rotate on the disk and exerting external force on the belt conveyor body, thereby causing the belt conveyor body to swing with the slewing bearing as the center. In this way, the swing of the belt conveyor body can be achieved under the premise of simple structure and low cost, and the driving motor does not need to be reversed, thereby reducing the influence of the inertial rotation of the motor and the time difference during the forward and reverse rotation of the driving motor on the reliability of the equipment, reducing the accident rate of the equipment and ensuring production efficiency.

[0009] Optionally, the lower end of the belt conveyor body is rotatably connected to a pulley, and the pulley is slidably connected to the support platform.

[0010] By adopting the above technical solution, the belt conveyor body can slide on the support platform through the pulley, and the friction between the belt conveyor body and the support platform is reduced by the pulley.

[0011] Optionally, a limiting groove is provided on the upper end surface of the support platform, and the pulley is slidably connected in the limiting groove.

[0012] By adopting the above technical solution, the sliding direction of the pulley can be limited by the limiting groove, thereby improving the stability of the pulley on the support platform.

[0013] Optionally, a sleeve is slidably connected to the end of the discharge end of the belt conveyor body, and a driving assembly is provided on one side of the sleeve for driving the sleeve to slide on the belt conveyor body. A partition is fixedly connected inside the sleeve, and the partition is arranged parallel to the conveying direction of the belt conveyor body. The partition divides the sleeve into an upper discharge port and a lower discharge port. A sealing plate is rotatably connected to the lower discharge port, and a torsion spring is provided inside the sleeve for keeping the sealing plate sealed at the lower discharge port. An adjusting member is provided inside the sleeve for adjusting the opening of the sealing plate.

[0014] By adopting the above technical scheme, the sleeve can be driven by the driving component to slide on the belt conveyor body, thereby changing the landing point of the material on the swinging belt conveyor, and the swinging trajectory of the end of the belt conveyor body at the discharge end is arc-shaped. When the end of the belt conveyor body at the discharge end swings from the edge of the swinging trajectory to the midpoint of the trajectory, the sleeve can move to one side of the slewing bearing under the action of the driving component, and make the material on the belt conveyor slide along the upper end surface of the partition and through the upper discharge port. When the end of the discharging end of the belt conveyor body swings from the midpoint of the swinging trajectory to the edge of the swinging trajectory, the driving assembly can drive the sleeve to move to the side away from the slewing bearing, thereby causing the adjusting member to drive the sealing plate to open, and at the same time, the end of the discharging end of the belt conveyor body is away from the partition, and the material on the belt conveyor body can directly fall into the sleeve and be discharged out of the sleeve through the lower discharge port, thereby compensating the transmission length of the belt conveyor body through the sleeve, so that the landing point trajectory of the material on the belt conveyor body during the swinging process changes from an arc to a straight line, thereby reducing the width of the equipment for collecting the material falling from the belt conveyor body, thereby facilitating the collection of material spilled on the swinging belt conveyor and improving the convenience of collecting the material falling from the belt conveyor body.

[0015] Optionally, the driving assembly includes a driving plate arranged below the belt conveyor body, the driving plate is provided with a driving groove, the driving groove is arranged along a direction perpendicular to the transmission direction of the belt conveyor body, the sleeve is rotatably connected to a driving block, and the driving block is slidably connected in the driving groove.

[0016] By adopting the above technical solution, without the need for additional driving force, the driving block can slide with the sleeve in the driving groove, and the sleeve can be limited by the driving groove. It can not only drive the sleeve to slide on the belt conveyor, but also make the sleeve always move in a straight line direction, thereby limiting the trajectory of the landing point of the material spilled from the sleeve.

[0017] Optionally, the adjusting member is configured as a connecting rope, one end of the connecting rope is fixedly connected to the sealing plate, and the other end of the connecting rope is fixedly connected to the discharge end of the belt conveyor body.

[0018] By adopting the above technical scheme, when the end of the discharging end of the belt conveyor body swings from the midpoint of the swinging trajectory to the edge of the swinging trajectory, the distance between the end of the discharging end of the belt conveyor body and the sealing plate will gradually increase, thereby under the action of the connecting rope, the sealing plate overcomes the force of the torsion spring and flips over, thereby canceling the blocking of the lower discharge port by the sealing plate, and the opening size of the sealing plate is positively correlated with the distance between the end of the discharging end of the belt conveyor body and the sealing plate, thereby the material on the belt conveyor can fall into the casing and be discharged from the lower discharge port along the casing, thereby making the material scattering more even.

[0019] Optionally, a plurality of limiting rings for limiting the position of the connecting rope are fixedly connected to the partition, and the connecting rope is placed in the limiting rings.

[0020] By adopting the above technical solution, the stretching or contraction position of the connecting rope can be limited by the limiting ring, thereby reducing the impact of the contraction of the connecting rope on the flow of materials in the casing.

[0021] Optionally, slide grooves are provided on both sides of the belt conveyor body, a slider opposite to the slide groove is fixedly connected to the inner wall of the sleeve, the slider is slidably connected in the slide groove, and the sleeve is slidably connected to the belt conveyor body through the slide groove and the slider.

[0022] By adopting the above technical solution, the sliding direction of the sleeve on the belt conveyor body can be limited by the slider and the slide groove, thereby improving the stability of the sleeve on the belt conveyor body.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The output shaft of the driving motor can drive the rotating disk to rotate, thereby driving the crank rocker to rotate on the disk and exerting external force on the belt conveyor body, thereby making the belt conveyor body swing with the slewing bearing as the center of the circle. In this way, the belt conveyor body can swing under the premise of simple structure and low cost, and the driving motor does not need to be reversed, which reduces the influence of the inertial rotation and time difference of the motor on the reliability of the equipment during the forward and reverse rotation of the driving motor, reduces the accident rate of the equipment, and ensures the production efficiency;

[0025] 2. The material can be discharged from the sleeve through the lower discharge port, thereby compensating the transmission length of the belt conveyor body through the sleeve, so that the landing point trajectory of the material on the belt conveyor body during the swinging process changes from an arc to a straight line, thereby reducing the width of the equipment for collecting the material falling from the belt conveyor body, thereby facilitating the collection of the material spilled on the swinging belt conveyor and improving the convenience of collecting the material falling from the belt conveyor body;

[0026] 3. Under the action of the connecting rope, the blocking plate overcomes the force of the torsion spring and flips over, thereby canceling the blocking of the lower discharge port by the blocking plate, and the opening size of the blocking plate is positively correlated with the distance between the end of the discharge end of the belt conveyor body and the blocking plate, so that the material on the belt conveyor can fall into the casing and be discharged from the lower discharge port along the casing, ultimately making the material scattering more even.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0033] The embodiment of the present application is: a swing belt conveyor, referring to Figure 1 , including a slewing bearing 2 mounted on the ground, a belt conveyor body 1 is arranged above the slewing bearing 2, one end of the belt conveyor body 1 is installed on the slewing bearing 2, the conveying direction of the material on the belt conveyor body 1 is from the end of the belt conveyor body 1 close to the slewing bearing 2 to the end of the belt conveyor body 1 away from the slewing bearing 2, and the discharging end of the belt conveyor body 1 is inclined toward the ground.

[0034] A support platform 3 is provided below the belt conveyor body 1. The support platform 3 is arranged in an arc shape, and the center of the cross section of the support platform 3 coincides with the axis of the slewing bearing 2. A limiting groove 31 is provided on the upper end surface of the support platform 3 along the circumferential direction of the support platform 3. Pulleys 11 are rotatably connected to both sides of the belt conveyor body 1, and the pulleys 11 are slidably connected in the limiting grooves 31. Thus, the belt conveyor body 1 is slidably connected to the support platform 3 through the pulleys 11 and the limiting grooves 31.

[0035] The implementation principle of Example 1 is: when transporting materials, the driving motor 4 can be started to drive the driving motor 4 to drive the rotating disk 41 to rotate, thereby causing the crank rocker 5 to drive the belt conveyor body 1 to swing around the axis of the slewing bearing 2, and at the same time the pulley 11 slides in the limit groove 31 on the support platform 3, thereby allowing the material to form an arc-shaped falling trajectory after falling off the belt conveyor body 1. Example

[0036] The difference from Example 1 is: Figure 2 and Figure 3The end of the discharging end of the belt conveyor body 1 is sleeved with a sleeve 6 for compensating the transmission length of the belt conveyor body 1. Both sides of the belt conveyor body 1 placed in the sleeve 6 are provided with slide grooves 12, which extend along the length direction of the belt conveyor body 1. Slide blocks 64 are fixedly connected to the inner side walls of the sleeve 6 opposite to the slide grooves 12. The shape of the slide blocks 64 matches the shape of the slide grooves 12 and the slide blocks 64 are slidably inserted in the slide grooves 12. Thus, the sleeve 6 is slidably connected to the belt conveyor body 1 through the slide blocks 64 and the slide grooves 12.

[0037] A driving assembly 7 for driving the sleeve 6 to slide on the belt conveyor body 1 is provided below the sleeve 6. The driving assembly 7 includes a driving plate 71 arranged below the sleeve 6. The extension direction of the driving plate 71 is perpendicular to the transmission direction of the belt conveyor body 1. A driving groove 711 arranged along the length direction of the driving plate 71 is provided on the upper end surface of the driving plate 71. A driving block 72 is slidably connected in the driving groove 711. The end of the driving block 72 away from the lower end of the slide groove 12 is rotatably connected to the lower end of the sleeve 6.

[0038] Reference Figure 2 and Figure 4 , a partition 61 is fixedly connected inside the sleeve 6, and the partition 61 is located at one side of the discharge end of the belt conveyor body 1. The partition 61 divides the sleeve 6 into an upper discharge port 62 and a lower discharge port 63. A blocking plate 631 for blocking the lower discharge port 63 is provided at the lower discharge port 63. The blocking plate 631 is set in a rectangular parallelepiped shape. A rotating shaft 632 is passed through and fixedly connected at the midpoint of the width direction of the blocking plate 631. The rotating shaft 632 is set along the length direction of the blocking plate 631, and the end of the rotating shaft 632 is rotatably connected to the inner side wall of the sleeve 6. Torsion springs 633 are sleeved on both ends of the rotating shaft 632. One end of the torsion spring 633 is fixedly connected to the blocking plate 631, and the other end of the torsion spring 633 is fixedly connected to the rotating shaft 632. Under the action of the torsion spring 633, the blocking plate 631 remains blocked at the lower discharge port 63.

[0039] An adjusting member for adjusting the opening of the sealing plate 631 is provided in the sleeve 6. In the figure, the adjusting member is configured as a connecting rope 8. One end of the connecting rope 8 is fixedly connected to the end of the discharge port of the belt conveyor body 1, and the other end of the connecting rope 8 is fixedly connected to one end of the sealing plate 631 close to the upper discharge port 62.

[0040] Therefore, when the distance between the belt conveyor body 1 and the partition 61 increases, the connecting rope 8 can apply external force to the blocking plate 631, so that the blocking plate 631 overcomes the force of the torsion spring 633 and causes the blocking plate 631 to begin to flip, thereby canceling the blocking of the lower discharge port 63 by the blocking plate 631. When the distance between the belt conveyor body 1 and the partition 61 decreases, under the action of the torsion spring 633, the blocking plate 631 will gradually return to its original position, until the blocking plate 631 completely blocks the lower discharge port 63, and the opening size of the lower discharge port 63 and the distance between the blocking plate 631 and the partition 61 change synchronously.

[0041] At the same time, in order to improve the stability of the connecting rope 8 in the sleeve 6, a plurality of limiting rings 9 are fixedly connected to the lower end of the partition 61. The limiting rings 9 are located on the same straight line and the connecting line between the plurality of limiting rings 9 is parallel to the axial direction of the sleeve 6. The connecting rope 8 is placed in the plurality of limiting rings 9.

[0042] The implementation principle of Example 2 is as follows: when the belt conveyor body 1 swings under the action of the driving motor 4, the swing trajectory of the end of the belt conveyor body 1 at the discharge end is arc-shaped, and the sleeve 6 will slide along the driving groove 711 under the limiting action of the driving groove 711 and the driving block 72. While sliding along the driving groove 711, the sleeve 6 will also slide back and forth on the belt conveyor body 1.

[0043] When the end of the discharge end of the belt conveyor body 1 swings from the edge of the swing trajectory to the midpoint of the trajectory, the sleeve 6 will move toward the side of the slewing bearing 2 and the distance between the end of the discharge end of the belt conveyor body 1 and the partition 61 will decrease, thereby allowing the material on the belt conveyor body 1 to fall directly on the partition 61 and slide out of the sleeve 6 along the upper end surface of the partition 61 through the upper discharge port 62.

[0044] When the end of the discharging end of the belt conveyor body 1 swings from the midpoint of the swing track to the edge of the swing track, the sleeve 6 will move away from the slewing bearing 2. At this time, the connecting rope 8 will drive the blocking plate 631 to open, and at the same time, the end of the discharging end of the belt conveyor body 1 will move away from the partition 61, so that the distance between the blocking plate 631 and the end of the discharging end of the belt conveyor body 1 increases, and the material on the belt conveyor body 1 can directly fall to the bottom of the sleeve 6 and can be discharged from the sleeve 6 through the lower discharge port 63. In this way, the transmission length of the belt conveyor body 1 is compensated by the sleeve 6, so that the landing point of the material after leaving the sleeve 6 is similar to a straight line.

[0045] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
