Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and specifically to a material steering device for a belt conveyor unit. Background Technology

[0002] In port and terminal freight transport, belt conveyors are commonly used as material transfer and transportation machinery. To improve conveying efficiency and change the conveying direction, multiple belt conveyors are often combined into a conveying system. In this system, the conveying path of materials is changed by using electric actuators to move the belt to another support roller or to switch belts, thus realizing the movement of materials between different belts. However, when a large amount of material adheres to the belt surface, the overall weight of the belt increases significantly. At this time, the electric actuator needs to overcome greater resistance to drive the belt to change direction. Due to the limited load-bearing capacity and power output of electric actuators, prolonged operation under high load conditions can easily lead to wear, deformation, or even damage to the mechanical components of the electric actuator. For example, the actuator rod may bend or break, and the motor may burn out due to overload.

[0003] Therefore, it is necessary to improve the material steering device of the belt conveyor unit. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a material steering device for belt conveyor units.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A material steering device for a belt conveyor includes a support leg, an upper transfer funnel fixedly connected to the support leg, a conical lower transfer funnel rotatably connected to the upper transfer funnel, a discharge port extending obliquely from the lower transfer funnel, a first bevel gear coaxially disposed on the outer side of the lower transfer funnel, a second bevel gear meshing with the first bevel gear rotatably disposed on the side wall of the upper transfer funnel, a working platform extending laterally from the support leg, a reduction gearbox disposed on the working platform, the second bevel gear being connected to the output end of a servo motor via the reduction gearbox, and the servo motor being electrically connected to an industrial control board.

[0007] Furthermore, the upper connecting funnel has a groove on its side wall, and the lower connecting funnel is embedded in the groove by a protrusion, with the protrusion and the groove connected by ball bearings.

[0008] Furthermore, the upper and lower surfaces of the protrusion are provided with balls, and the balls on the upper surface of the protrusion are misaligned with the balls on the lower surface.

[0009] Furthermore, a first pawl is provided on the side of the second bevel gear away from the upper transfer funnel, and a second pawl is provided coaxially on the drive shaft of the reduction gearbox, with the two pawls being compatible with each other.

[0010] Furthermore, a limit block is radially arranged between the drive shaft and the second jaw and the servo motor. The second jaw and the drive shaft are slidably connected via a stepped shaft, the diameter of which is smaller than that of the drive shaft. The side of the limit block away from the reduction gearbox is connected to the second jaw via an elastic component. When the servo motor is overloaded, the second jaw disengages from the first jaw and compresses the elastic component, causing the servo motor to idle and thus providing overload protection.

[0011] Furthermore, the elastic component includes one of a spring, a hydraulic rod, or a pneumatic rod.

[0012] Furthermore, a vision sensor is connected to one side of the reduction gearbox via a telescopic rod and a hinge. The vision sensor faces the feed end of the upper transfer funnel. The vision sensor is electrically connected to the industrial control board, which is communicatively connected to the background operating system to enable remote operation.

[0013] Furthermore, the lower connecting funnel is axially provided with a fixing block, and the lower surface of the fixing block is provided with a spherical groove. The spherical groove is connected to a rotating support rod through a spherical surface that fits with it with a clearance. The bottom surface of the rotating support rod is fixedly provided with a base, and the base is fixed to the ground with bolts.

[0014] Furthermore, the work platform is equipped with stairs.

[0015] Furthermore, the inclined surface inside the lower transfer funnel is provided with a ceramic wear-resistant plate.

[0016] The advantages and beneficial effects of this utility model are as follows:

[0017] 1. This utility model changes the direction of the funnel end by using two upper and lower transition funnels connected by a split rotating mechanism and bevel gears to achieve relative rotation. The structure is simple and easy to maintain. The precise control of the funnel end direction is achieved by using a servo motor to drive a reduction gearbox.

[0018] 2. When the servo motor is overloaded, the second jaw disengages from the first jaw and compresses the spring, causing the servo motor to idle and thus providing overload protection. This design effectively prevents equipment damage caused by overload and extends the equipment's service life.

[0019] 3. Remote operation is achieved through an electrical connection between the vision sensor and the industrial control board, which in turn communicates with the backend operating system. This allows operators to monitor and control the equipment from a distance, improving work efficiency and safety.

[0020] 4. The upper and lower transition funnels are connected by ball bearings, which reduces friction. Ball bearings are also provided on both the upper and lower sides of the protrusion, which effectively reduces the relative misalignment of the two transition funnels. A fixing block is provided axially in the lower transition funnel. A spherical groove is opened on the lower surface of the fixing block. A rotating support rod is connected to the spherical groove through a spherical surface that fits with it. A base is fixedly installed on the bottom surface of the rotating support rod, and the base is fixed to the ground with bolts. Attached Figure Description

Detailed Implementation

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0027] Example

[0028] Please see Figures 1-3 This utility model provides a material steering device for a belt conveyor, which mainly consists of a support leg 1, a drive shaft 17, a servo motor 9, an upper transfer funnel 2, a lower transfer funnel 3, a bevel gear set (including a first bevel gear 5 and a second bevel gear 6), a reduction gearbox 8, an industrial control board 10, and related connecting components.

[0029] Support leg 1 is used to stabilize the entire device and extends to provide a working platform 7. A servo motor 9 is installed on the working platform 7, and the output end of the servo motor 9 is connected to a drive shaft 17 via a reduction gearbox 8. The upper transfer funnel 2 is rotatably connected to the conical lower transfer funnel 3, and the lower transfer funnel 3 extends obliquely to provide a discharge port 4.

[0030] A first bevel gear 5 is coaxially mounted on the outer edge of the feed end of the lower transfer funnel 3, while a second bevel gear 6, meshing with the first bevel gear 5, is rotatably mounted on the side wall of the upper transfer funnel 2. A reduction gearbox 8 is mounted on the working platform 7. The second bevel gear 6 of the drive shaft 17 is connected to the output end of the servo motor 9 through the reduction gearbox 8, and the servo motor 9 is electrically connected to the industrial control board 10, which in turn communicates with the background operating system to achieve remote operation.

[0031] To ensure stable operation and precise coordination of the device, a groove 11 is provided on the side wall of the upper transfer funnel 2. The lower transfer funnel 3 of the drive shaft 17 is embedded in the groove 11 through a protrusion 12, and the protrusion 12 and the groove 11 of the drive shaft 17 are connected by balls 13. Specifically, balls 13 are provided on both the upper and lower surfaces of the protrusion 12, and the balls 13 on the upper surface of the protrusion 12 are misaligned with the balls 13 on the lower surface to ensure the concentricity of the two transfer funnels and prevent them from sliding relative to each other.

[0032] A first pawl 14 is provided on the side of the second bevel gear 6 away from the drive shaft 17 where the funnel 2 connects, and a second pawl 15 is coaxially provided on the drive shaft 17 of the reduction gearbox 8, the two being mutually compatible. Simultaneously, a limit block 16 is radially provided between the second pawl 15 and the servo motor 9 on the drive shaft 17. The second pawl 15 and the drive shaft 17 are slidably connected via a stepped shaft 18, the diameter of which is smaller than the diameter of the limit block 16 on the side of the drive shaft 17 away from the reduction gearbox 8, and an elastic member 19 passes through the stepped shaft 18 on the side away from the reduction gearbox 8. The elastic member 19 is preferably any one of a spring, hydraulic rod, or pneumatic rod. The elastic member is connected to the second pawl 15. When the servo motor 9 is overloaded, the second pawl 15 disengages from the first pawl 14 and squeezes the elastic member 19, causing the servo motor 9 to idle, thus forming an overload protection mechanism for the motor. The first pawl 14 and the second pawl 15 are preferably end-face gears with beveled surfaces for easy disengagement.

[0033] In addition, a vision sensor 22 is connected to one side of the reduction gearbox 8 via a telescopic rod 20 and a hinge 21. The vision sensor 22 faces the feed end of the transfer funnel 2 on the drive shaft 17 and is electrically connected to the industrial control board 10. A fixing block 23 is axially arranged on the lower transfer funnel 3. A spherical groove 24 is formed on the lower surface of the fixing block 23. A rotating support rod 26 is connected to the spherical groove 24 through a spherical surface 25 that fits with it. A base 27 is fixedly installed on the bottom surface of the rotating support rod 26. The base 27 is fixed to the ground by bolts 28, thereby providing stable support for the lower transfer funnel 3.

[0034] To facilitate operation and maintenance, the work platform 7 is equipped with a ladder. In addition, considering the wear and tear on the interior of the lower transfer funnel 3 caused by materials, a ceramic wear-resistant plate 29 is installed on the inclined surface inside the lower transfer funnel 3.

[0035] The working principle of this invention is as follows: the material to be redirected is fed into the upper transfer funnel 2 through the feed inlet via a belt conveyor. Due to the height difference and angle between the upper transfer funnel 2 and the lower transfer funnel 3, the material gradually moves into the lower transfer funnel 3 under the action of gravity and flows out from the discharge port 4 to the lower belt conveyor for material transport. When the flowing material needs to be redirected, the operator can adjust the rotation parameters of the servo motor 9 through the on-site or remote operation of the industrial control board 10 to ensure that the material can be redirected in the expected direction and angle. The vision sensor 22 continuously monitors the feed end and transmits real-time image data to the industrial control board 10. The operator can observe the feeding situation through the background operating system to ensure that the material supply is uniform and stable, and to avoid blockages or material interruptions. During the operation of the device, when the servo motor 9 is overloaded (e.g., the material flow rate is too large, or the material particles are too large and cause jamming), the second claw 15 and the first claw 14 will automatically disengage. At this time, the elastic component 19 connected to it will be squeezed and contracted, causing the servo motor 9 to enter an idling state.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
