Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically a belt conveyor with an adjustable tilt angle. Background Technology

[0002] A belt conveyor, also known as a belt conveyor, comes in stationary and mobile types. It is a simple and efficient continuous conveying machine that uses a flexible conveyor belt as the material-carrying and traction component. An endless conveyor belt wraps around a drive drum and a redirecting drum. The upper and lower branches between the two drums are supported by several idlers. Material is placed on the upper branch, and the friction between the drive drum and the belt pulls the conveyor belt and the material. It is suitable for conveying bulk materials and packaged goods horizontally and at an incline, and can also be used in assembly lines for certain processes. It has a simple structure, stable and reliable operation, strong adaptability to materials, large conveying capacity, low power consumption, and wide application.

[0003] Upon investigation, a Chinese utility model patent discloses a belt conveyor with an adjustable tilt angle (publication number: CN214568617U), which includes a base plate and a belt conveyor body. The belt conveyor body consists of an annular belt, rollers rotatably connected to the front and rear ends of the inner wall of the annular belt, a motor that drives the rollers to rotate, and support frames that are respectively supported on the left and right sides of the two rollers.

[0004] Although the aforementioned patent enables the angle adjustment device of the movable belt conveyor to be adjusted by personnel when used with transfer vehicles of different sizes through the setting of the arc-shaped guide device and the support device, the adjustment process requires the staff to limit the position of multiple support legs in sequence, and the staff needs to rotate the fixing bolts multiple times to limit and fix the guide strip in the guide cylinder. The operation process is cumbersome and time-consuming.

[0005] Therefore, this utility model provides a belt conveyor with an adjustable tilt angle to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides a belt conveyor with a convenient adjustable tilt angle, aiming to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: It includes a base and a belt conveyor body rotatably mounted on the base. Two first guide cylinders, a first guide strip, a second guide cylinder, and a second guide strip are provided between the belt conveyor body and the base. Gears are rotatably connected inside each of the two first guide cylinders. Racks are provided on each of the two first guide strips, and the gears mesh with the racks. Multiple limiting holes are provided on the side walls of each of the two second guide strips. A mounting box is fixedly connected to the side walls of each of the two second guide cylinders, and a limiting mechanism is provided inside the mounting box. The limiting mechanism includes a limiting rod for restricting the sliding of the second guide strip.

[0010] As a preferred technical solution of this application, a rotating rod is coaxially fixed between the two gears, a connecting box is fixedly connected to the side wall of the first guide cylinder, and a worm gear and a worm are rotatably connected inside the connecting box, with the worm gear meshing with the worm.

[0011] As a preferred technical solution of this application, the worm gear and the gear are fixedly coaxially, and a motor is fixedly connected to the side wall of the connecting box, and the output end of the motor is fixedly coaxially with the worm.

[0012] As a preferred technical solution of this application, a baffle and an electromagnet are fixedly connected inside the mounting box. One end of the limiting rod passes through the side wall of the second guide cylinder and is inserted into the limiting hole. The other end of the limiting rod slides through the side wall and the baffle of the mounting box.

[0013] As a preferred technical solution of this application, the limiting mechanism further includes:

[0014] A baffle plate and an iron plate, both of which are fixedly connected to a limiting rod;

[0015] A spring is sleeved on a limiting rod, and both ends of the spring are fixedly connected to a baffle and a baffle plate, respectively.

[0016] As a preferred technical solution of this application, the first guide bar and the second guide bar are slidably connected to the first guide cylinder and the second guide cylinder respectively, both the first guide cylinder and the second guide cylinder are fixedly connected to the base, and both the first guide bar and the second guide bar are fixedly connected to the belt conveyor body.

[0017] (III) Beneficial Effects

[0018] By setting up meshing racks and gears, the conveyor belt body can be driven to adjust its angle. Simultaneously, a worm gear and worm can limit the first guide bar after adjustment, and a limiting mechanism at the second guide bar can also limit it. This limits multiple support points of the conveyor belt body, improving its stability. Furthermore, the limiting mechanism is electrically connected to the motor that drives the gears. When the gears adjust the first guide bar, the limiting mechanism releases the second guide bar; when the adjustment of the first guide bar stops, the limiting mechanism re-limits and fixes the second guide bar. This allows for simultaneous limiting of both the first and second guide bars, making the operation simple and quick, and significantly reducing the time required for adjusting the conveyor belt body's angle.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a belt conveyor with a convenient adjustable tilt angle, such as... Figures 1-5 The technical solution includes a base 1 and a conveyor belt body 2 rotatably mounted on the base 1. Two first guide cylinders 3, a first guide strip 4, a second guide cylinder 8, and a second guide strip 9 are provided between the conveyor belt body 2 and the base 1. Gears 13 are rotatably connected inside each of the two first guide cylinders 3. Racks 12 are provided on each of the two first guide strips 4, and the gears 13 mesh with the racks 12. Multiple limiting holes 10 are provided on the side walls of each of the two second guide strips 9. Mounting boxes 11 are fixedly connected to the side walls of each of the two second guide cylinders 8, and limiting mechanisms are provided inside the mounting boxes 11. The limiting mechanisms include limiting rods 16 for restricting the sliding of the second guide strips 9. The first guide strips 4 and 9 are slidably connected to the first guide cylinders 3 and 8, respectively. Both the first guide cylinders 3 and 8 are fixedly connected to the base 1, and both the first guide strips 4 and 9 are fixedly connected to the conveyor belt body 2.

[0028] A rotating rod 5 is coaxially fixed between two gears 13. A connecting box 6 is fixedly connected to the side wall of the first guide cylinder 3. A worm gear 14 and a worm 15 are rotatably connected inside the connecting box 6, and the worm gear 14 meshes with the worm 15. The worm gear 14 is coaxially fixed with the gear 13. A motor 7 is fixedly connected to the side wall of the connecting box 6. The output end of the motor 7 is coaxially fixed with the worm 15. By setting the meshing rack 12 and gear 13, the belt conveyor body 2 can be driven to adjust the angle. At the same time, the worm gear 14 and worm 15 can adjust the angle after adjustment. The first guide bar 4 is limited, and the limiting mechanism set at the second guide bar 9 can limit the second guide bar 9, limiting multiple support points of the belt conveyor body 2, thereby improving the stability of the belt conveyor body 2; the rotation of the gear 13 is limited by the self-locking between the worm wheel 14 and the worm 15. Rotating the worm 15 can drive the meshing worm wheel 14 to rotate. At this time, starting the motor 7 can drive the gear 13 to rotate. Conversely, rotating the worm wheel 14 cannot drive the meshing worm 15 to rotate, which can prevent the first guide bar 4 from sliding down due to gravity.

[0029] A baffle 19 and an electromagnet 21 are fixedly connected inside the mounting box 11. One end of the limiting rod 16 passes through the side wall of the second guide cylinder 8 and is inserted into the limiting hole 10. The other end of the limiting rod 16 slides through the side wall of the mounting box 11 and the baffle 19. It should be noted that the motor 7 is electrically connected to the electromagnet 21. When the motor 7 is started, the electromagnet 21 is energized and becomes magnetic. When the motor 7 is turned off, the electromagnet 21 is de-energized and loses its magnetism. When the drive gear 13 adjusts the first guide bar 4, the limiting mechanism releases the limiting of the second guide bar 9. When the adjustment of the first guide bar 4 is stopped, the limiting mechanism can re-limit and fix the second guide bar 9, thereby simultaneously limiting the first guide bar 4 and the second guide bar 9. The operation process is simple and quick, which can greatly save the angle adjustment time of the belt conveyor body 2. The limiting mechanism also includes a baffle 17 and an iron plate 20, both of which are fixedly connected to the limiting rod 16. The limiting mechanism also includes a spring 18, which is sleeved on the limiting rod 16, and the two ends of the spring 18 are fixedly connected to the baffle 17 and the baffle 19 respectively.

[0030] It should be noted that the electromagnet 21 is a device that generates electromagnetism when energized. A conductive winding matching its power is wound around the outside of the iron core. This coil carrying current has magnetism like a magnet. Both the motor 7 and the electromagnet 21 are connected to an external power source through wires. The external power source includes a battery for providing power to the motor 7 and the electromagnet 21 and a control switch for controlling their start and stop. The external power source is existing technology. The specific model and specifications of the motor 7 and the electromagnet 21 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts existing technology in this field, so it will not be described in detail.

[0031] In summary: When adjusting the angle of the belt conveyor body 2, the electromagnet 21 is energized and attracts the iron plate 20 when the motor 7 is started. The iron plate 20 drives the limiting rod 16 to move out of the limiting hole 10. At the same time, the baffle 17 on the limiting rod 16 compresses the spring 18. The motor 7 drives the worm 15 to rotate. The rotating worm 15 drives the meshing worm wheel 14 and the gear 13 fixed coaxially with the worm wheel 14 to rotate. The gear 13 drives the first guide bar 4 to slide through the meshing rack 12, thereby adjusting the angle of the belt conveyor body 2.

[0032] When the conveyor body 2 is adjusted to a suitable angle, the electromagnet 21 is de-energized and no longer attracts the iron plate 20 when the motor 7 is turned off. At this time, the compressed spring 18 returns to its original position and pushes the baffle 17 to move. The baffle 17 drives the limiting rod 16 to insert into the limiting hole 10 on the second guide bar 9. The meshing worm gear 14 and worm 15 have a self-locking property, which can limit the rotation of the gear 13 and prevent the first guide bar 4 from sliding down due to gravity. This achieves the limiting and fixing of multiple support points of the conveyor body 2.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
