It should be understood that the specific embodiments described herein are only for explaining the present utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to the present utility model are shown in the drawings, not all of the structures.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments.

[0022] Please see Figures 1 to 3The present invention provides a belt conveyor backstop device comprising a bracket 1, a roller 2, a conveyor belt 3, a motor 4, a channel steel 5, and a backstop belt 6;
[0023] The roller 2 includes a drive roller 21 and a redirecting roller 22, which are respectively disposed at both ends of the support 1 and are rotatably connected to the support 1. The conveyor belt 3 is installed between the drive roller 21 and the redirecting roller 22. The motor 4 is disposed on the support 1, and the output shaft of the motor 4 is fixedly connected to one end of the drive roller 21. The channel steel 5 is disposed between the drive roller 21 and the redirecting roller 22 and is located at the end of the support 1 closer to the drive roller 21. The channel steel 5 is fixedly connected to the support 1. One end of the anti-reverse belt 6 is fixedly disposed on the channel steel 5.
[0024] When the belt conveyor rotates forward, the end of the anti-reverse belt 6 away from the channel steel 5 moves with the conveyor belt 3 toward the redirecting roller 22. When the belt conveyor stops running, the conveyor belt 3 rotates in reverse under the action of the material's gravity, and the anti-reverse belt 6 moves with the reversed conveyor belt 3. The anti-reverse belt 6 enters between the conveyor belt 3 and the drive roller 21, and friction is generated between the anti-reverse belt 6, the drive roller 21, and the conveyor belt 3. The belt conveyor stops rotating in reverse under the action of friction, so that the conveyor belt 3 does not continuously move backward due to the action of the material's gravity when the motor 4 stops working.
[0025] In this embodiment, the support 1 is further provided with a blocking assembly 7, which includes a first rotating shaft 71, a second rotating shaft 72, a baffle 73, and a driving part 74. The first rotating shaft 71 is disposed between the channel steel 5 and the driving roller 21 and is rotatably connected to the support 1. The second rotating shaft 72 is disposed between the channel steel 5 and the redirecting roller 22 and is rotatably connected to the support 1. Two baffles 73 are provided, which are respectively disposed on the first rotating shaft 71 and the second rotating shaft 72 and are respectively fixedly connected to the first rotating shaft 71 and the second rotating shaft 72. The driving part 74 is disposed on the driving roller 21 and is connected to both the first rotating shaft 71 and the second rotating shaft 72. The driving part 74 is used to drive the first rotating shaft 71 and the second rotating shaft 72 to rotate.
[0026] When the motor 4 is running, the drive roller 21 rotates with the output shaft of the motor 1. At this time, the conveyor belt 3 rotates with the drive roller 21 under the action of friction. When the motor 1 stops running, the conveyor belt 3 runs in the opposite direction under the action of the material's gravity. The drive roller 21 reverses, and the drive unit 74 is activated. The drive unit 74 drives the first rotating shaft 71 and the second rotating shaft 72 to rotate. The two baffles 73 rotate with the first rotating shaft 71 and the second rotating shaft 72. The two baffles 73 separate, and the anti-reverse belt 6 stored on the baffles 73 falls off, so that the anti-reverse belt 6 can move with the conveyor belt 3 to between the conveyor belt 3 and the drive roller 21, thereby stopping the reverse running of the conveyor belt 3 under the action of friction.
[0027] In this embodiment, the drive unit 74 includes a first driving gear 741, a one-way clutch 742, a first driven gear 743, a second driving gear 744, and a second driven gear 745. The first driving gear 741 is disposed at the end of the drive roller 21 away from the motor 4 and is coaxially and fixedly connected to the drive roller 21. The one-way clutch 742 is mounted on the first rotating shaft 71. The first driven gear 743 is mounted on the one-way clutch 742 and meshes with the first driving gear 741. The second driving gear 744 is disposed on the first rotating shaft 71 and is coaxially and fixedly connected to the first rotating shaft 71. The second driven gear 745 is disposed on the second rotating shaft 72 and is coaxially and fixedly connected to the second rotating shaft 72. The second driven gear 745 meshes with the second driving gear 744.
[0028] When the conveyor belt 3 is running in the forward direction, the drive roller 21 drives the first drive gear 741 to rotate in the forward direction. The first drive gear 741 drives the first driven gear 743 to rotate through meshing. Due to the action of the one-way clutch 742, the first driven gear 743 is not locked with the first rotating shaft 71, and the first driven gear 743 spins freely on the first rotating shaft 71. At this time, the first rotating shaft 71 and the second rotating shaft 72 are stationary and do not rotate.
[0029] When the conveyor belt 3 rotates in the reverse direction, the drive roller 21 drives the first drive gear 741 to rotate in reverse, and the first driven gear 743 follows the first drive gear 741 to rotate in reverse. At this time, the first driven gear 743 is locked with the first rotating shaft 71 under the action of the one-way clutch 742. The first driven gear 743 drives the first rotating shaft 71 to rotate. At the same time, the second drive gear 744 rotates, and the second driven gear 745 follows the second drive gear 744 to rotate. The second driven gear 745 is fixedly connected to the second rotating shaft 72. The second rotating shaft 72 rotates, thereby causing the two baffles 73 to separate, and the anti-reverse belt 6 placed on the baffles 73 falls off.
[0030] In this embodiment, the first driving gear 741 has more teeth than the first driven gear 743, and the first driven gear 743, the second driving gear 744, and the second driven gear 745 have the same number of teeth.
[0031] When the drive roller 21 drives the first drive gear 741 to reverse, since the number of teeth of the first drive gear 741 is greater than the number of teeth of the first driven gear 743, the rotational speed of the first rotating shaft 71 is greater than the rotational speed of the drive roller 21, so that the anti-reverse belt 6 can fall off the baffle in a shorter time, thereby enabling the conveyor belt 3 to stop reversing more quickly.
[0032] In this embodiment, a winding assembly 8 is provided on the support 1. The winding assembly 8 includes a spool 81, a winding rope 82, and a hand crank 83. The spool 81 is rotatably mounted on the support 1 and located above the channel steel 5. Two winding ropes 82 are provided, and the two winding ropes 82 are respectively wound around the two ends of the spool 81. The end of the winding rope 82 away from the spool 81 is fixedly connected to the end of the anti-reverse belt 6 away from the channel steel 5. The hand crank 83 is fixedly mounted on one end of the spool 81.
[0033] In this embodiment, the winding assembly 8 further includes a third driving gear 84 and a third driven gear 85. The third driving gear 84 is disposed on the winding shaft 81 and is coaxially and fixedly connected to the winding shaft 81. The third driven gear 85 is disposed at one end of the second rotating shaft 72 away from the second driven gear 745 and is coaxially and fixedly connected to the second rotating shaft 72. The third driven gear 85 meshes with the third driving gear 84.
[0034] When motor 1 is running, conveyor belt 3 is running in the forward direction, and anti-backflow belt 6 follows the movement of conveyor belt 3. When anti-backflow belt 6 is disengaged from drive drum 21, the operator turns hand crank 83, and reel 81 rotates with hand crank 83. The storage rope 82 is wound around reel 81, thereby realizing the storage of anti-backflow belt 6.
[0035] At the same time, the third driving gear 84 rotates with the reel 81. The third driving gear 84 meshes with the third driven gear 85. The third driving gear 84 drives the third driven gear 85 to rotate, causing the second shaft 72 to rotate. The second driven gear 745 rotates with the second shaft 72. The second driven gear 745 drives the second driving gear 744 to rotate, causing the first shaft 71 to start rotating, thereby closing the two baffles 73, and allowing the anti-reverse belt 6 to be stored at the top of the baffle 73.
[0036] This belt conveyor backstop device includes a support 1, a roller 2, a conveyor belt 3, a motor 4, a channel steel 5, and a backstop belt 6. The roller 2 includes a drive roller 21 and a redirecting roller 22, which are respectively located at both ends of the support 1 and are rotatably connected to the support 1. The conveyor belt 3 is installed between the drive roller 21 and the redirecting roller 22. The motor 4 is mounted on the support 1, and the output shaft of the motor 4 is fixedly connected to one end of the drive roller 21. The channel steel 5 is located between the drive roller 21 and the redirecting roller 22 and is fixedly connected to the support 1. One end of the backstop belt 6 is fixedly mounted on the channel steel 5. This belt conveyor backstop device, through the arrangement of various structures, makes it difficult for the conveyor belt 3 to continuously reverse due to the gravity of the material after the belt conveyor stops running.
