Description

Technical Field

[0001] This utility model relates to the field of port transportation equipment technology, and in particular to an anti-jamming transportation device. Background Technology

[0002] Domestic ports commonly use belt conveyor systems for transporting bulk dry cargo such as iron ore and bauxite. After unloading the cargo from the ship, the unloader transfers it to the stockyard via belt conveyor. Stacker-reclaimers then transfer the cargo from the stockyard to a series of belt conveyors for loading onto trains, or to the ship loader for loading onto the vessel. Belt conveyor systems offer advantages such as high efficiency, low energy consumption, and large capacity. As a crucial link in loading and unloading operations, belt conveyors play a vital connecting role. Each belt conveyor has guide funnels installed upstream and downstream, positioned above the belt to transfer bulk dry cargo onto the conveyor.

[0003] Currently, commonly used material guide funnels are often installed at a low position to prevent spillage when materials fall from a high place to a low place, and the distance between the material guide funnel and the belt is not adjustable. However, due to the complexity of dry bulk cargo, the materials often contain large stones, ironware and other debris, which can get stuck between the material guide funnel and the belt during the material transfer process. As the belt continues to drive, the stones and other debris can easily cause the belt to tear, resulting in significant economic losses and safety risks. Utility Model Content

[0004] This invention addresses the problem that the current material guide hopper and belt are located too close together, and their relative positions are difficult to adjust, making it easy for large stones and other debris to damage the belt, which can lead to economic losses and safety risks. This invention proposes an anti-jamming transport device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides an anti-jamming transport device, including a belt mechanism, which includes a drive wheel and a belt wound around the drive wheel, and a material guiding mechanism. The material guiding mechanism is disposed on one side of the belt along a first direction. The material guiding mechanism includes a first material guiding body, a second material guiding body, and a connecting component. The first material guiding body is provided with a material guiding trough for accommodating materials, and the second material guiding body is provided with a discharge port that is movably connected to the material guiding trough. A gap is provided between the discharge port and the belt for materials to pass through. The first material guiding body and the second material guiding body are movably connected by the connecting component, and the second material guiding body can move relative to the first material guiding body along the first direction to adjust the length of the gap in the first direction.

[0007] Furthermore, the connecting assembly includes multiple elastic elements, which are evenly distributed between the first material guiding body and the second material guiding body. One end of each elastic element is fixedly connected to the first material guiding body, and the other end is fixedly connected to the second material guiding body.

[0008] Furthermore, the connecting assembly includes multiple guide rods, one end of which is fixedly connected to the second material guiding body and extends along the first direction. The first material guiding body is provided with a guide groove, and the guide rod is connected to the guide groove. The guide rod can move within the guide groove, and an elastic element is sleeved on the guide rod.

[0009] Furthermore, a limiting block is movably connected to one end of the guide rod relative to the second guide body. The limiting block can move along the axial direction of the guide rod, and the radial dimension of the limiting block is greater than the diameter of the guide groove.

[0010] Furthermore, an elastic buffer pad is provided on the end face of the first material guide body near the second material guide body.

[0011] Furthermore, a ramp is provided on the side of the discharge port along the conveying direction of the belt. The ramp includes a first ramp and a second ramp. One end of the first ramp and one end of the second ramp are connected, and the inclination directions of the first ramp and the second ramp are opposite. The first ramp is inclined outward from the discharge port along a first direction.

[0012] Furthermore, both the first and second inclined surfaces are equipped with elastic protective pads.

[0013] Furthermore, the end of the discharge port near the belt is provided with an elastic skirt along the circumference, and one end of the elastic skirt is in contact with the belt.

[0014] Furthermore, an elastic telescopic shell is connected between the first and second material guiding bodies, and the elastic telescopic shell covers at least the connection between the material guiding channel and the discharge port.

[0015] As can be seen from the above technical solutions, the advantages of this utility model are:

[0016] This invention sets the material guiding mechanism as a first material guiding body and a second material guiding body that are movably connected. When debris passes the edge of the discharge port, it abuts against the second material guiding body and pushes the second material guiding body to move in the first direction, thereby adjusting the distance between the discharge port and the belt, ensuring the normal passage of larger materials, effectively avoiding belt tearing, improving the service life of the device, reducing operating costs, and improving work safety.

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] Please see Figures 1-2An anti-jamming transport device includes a belt mechanism, which includes a drive wheel 120 and a belt 110 wound around the drive wheel 120. It also includes a material guiding mechanism 200, which is disposed on one side of the belt 110 along a first direction. The material guiding mechanism 200 includes a first material guiding body 210, a second material guiding body 220, and a connecting assembly 300. The first material guiding body 210 has a material guiding trough 211 for receiving material. The second material guiding body 220 has a discharge port 221 movably communicating with the material guiding trough 211. A gap 230 for material to pass through is provided between the discharge port 221 and the belt 110. The first material guiding body 210 and the second material guiding body 220 are movably connected by the connecting assembly 300, and the second material guiding body 220 can move relative to the first material guiding body 210 along the first direction to adjust the length of the gap 230 in the first direction.

[0024] In this embodiment, as Figure 1 As shown, the belt mechanism is placed horizontally, with the belt 110 wound around the drive wheel 120 and conveying material horizontally. The first direction is vertical. The material guiding mechanism 200 is installed vertically on the upper side of the belt 110. The material guiding mechanism 200 includes a first material guiding body 210 located on the upper side and a second material guiding body 220 located on the lower side. The first material guiding body 210 has a material guiding groove 211 inside, which can accommodate material. The second material guiding body 220 has a discharge port 221. One end of the discharge port 221 is connected to the guide wheel 120 in the vertical direction. The material trough 211 is movably connected, with the other end facing the belt 110. There is a gap 230 between the discharge port 221 and the belt 110, so that the material falling onto the belt 110 through the discharge port 221 can pass through the gap 230 as the belt 110 moves. In addition, the lower end of the first material guiding body 210 and the upper end of the second material guiding body 220 are movably connected by a connecting component 300, and the second material guiding body 220 can move in the vertical direction, thereby adjusting the vertical distance between the discharge port 221 and the belt 110, that is, the length of the gap 230 in the vertical direction.

[0025] In actual operation, initially, the gap 230 between the discharge port 221 of the second material guide body 220 and the belt 110 is of normal size. This ensures that materials of normal size can pass through while preventing spillage. The material is first placed in the guide trough 211 of the first material guide body 210, and then falls through the discharge port 221 onto the belt 110, where it is conveyed to the appropriate position as the belt 110 moves. When larger materials, such as stones or ironware, fall from the discharge port 221, the... When larger debris moves along the belt 110 to the edge of the discharge port 221, the debris comes into contact with the second guide body 220 and pushes the second guide body 220 upward relative to the first guide body 210, thereby increasing the vertical distance between the discharge port 221 and the belt 110, thus facilitating the passage of the larger debris. After the debris passes, the second guide body 220 can return to its initial state by gravity, thereby effectively preventing material spillage and ensuring the normal operation of the conveying work.

[0026] In the above structure, by setting the material guiding mechanism 200 as a first material guiding body 210 and a second material guiding body 220 that are movably connected, when debris passes through the edge of the discharge port 221, it abuts against the second material guiding body 220 and pushes the second material guiding body 220 to move in the first direction, thereby adjusting the distance between the discharge port 221 and the belt 110, thus ensuring the normal passage of larger materials, effectively preventing materials from getting stuck between the discharge port 221 and the belt 110, thereby preventing the belt 110 from tearing, improving the service life of the device, reducing the cost of use, and improving work safety.

[0027] In the specific structure of the connecting component 300, the connecting component 300 includes a plurality of elastic elements 310, which are evenly distributed between the first material guiding body 210 and the second material guiding body 220. One end of the elastic element 310 is fixedly connected to the first material guiding body 210, and the other end is fixedly connected to the second material guiding body 220.

[0028] In this embodiment, as Figure 2As shown, the lower end of the first material guiding body 210 has a rectangular structure, and correspondingly, the upper end of the second material guiding body 220 also has a rectangular structure. The connecting assembly 300 includes multiple elastic elements 310, which are evenly distributed circumferentially along the lower end of the first material guiding body 210. The upper end of the elastic element 310 is fixedly connected to the lower end of the first material guiding body 210, and the lower end of the elastic element 310 is fixedly connected to the upper end of the second material guiding body 220. The first material guiding body 210 and the second material guiding body 220 are elastically connected through the elastic elements 310. In the initial state, the elastic element 310 is normally extended. When a larger object passes through, it abuts against the second material guiding body 220 and pushes the second material guiding body 220 upward. At this time, the elastic element 310 contracts under force. After the object passes through, the elastic element 310, through elastic action and gravity, drives the second material guiding body 220 downward to the initial position. By incorporating an elastic element 310, the first guide body 210 and the second guide body 220 are elastically connected. This effectively absorbs and isolates the impact and vibration of debris on the second guide body 220, while also adapting to changes in debris size and load. Since the elastic element 310 has a certain deformation capacity, it can adaptively adjust to a certain extent when the size or load of the debris changes, thereby maintaining overall stability and passability. In this embodiment, the elastic element 310 can be a spring structure.

[0029] Specifically, the connecting assembly 300 includes a plurality of guide rods 320. One end of the guide rod 320 is fixedly connected to the second material guiding body 220, and the guide rod 320 extends along the first direction. The first material guiding body 210 is provided with a guide groove 212. The guide rod 320 is connected to the guide groove 212, and the guide rod 320 can move within the guide groove 212. The elastic element 310 is sleeved on the guide rod 320.

[0030] Furthermore, in this embodiment, the number of guide rods 320 is the same as the number of elastic elements 310. The bottom end of the guide rod 320 is fixed on the second material guiding body 220, and the elastic element 310 is sleeved on the guide rod 320. The guide rod 320 extends vertically. Correspondingly, multiple guide grooves 212 are provided on the first material guiding body 210. During connection, the upper end of the guide rod 320 passes through the guide groove 212, and the guide rod 320 and the guide groove 212 are inserted into each other. When the second material guiding body 220 moves vertically, the guide rod 320 moves within the guide groove 212. By setting the guide rod 320 and the guide groove 212, the relative movement of the first material guiding body 210 and the second material guiding body 220 can be guided and limited, effectively preventing the second material guiding body 220 from deviating during movement, thereby affecting the normal passage of material from the guide groove 211 through the outlet 221, and ensuring that the material can fall normally during the movement of the second material guiding body 220.

[0031] More specifically, a limiting block 330 is movably connected to one end of the guide rod 320 relative to the second material guiding body 220. The limiting block 330 can move along the axial direction of the guide rod 320, and the radial dimension of the limiting block 330 is larger than the diameter of the guide groove 212. In this embodiment, a limiting block 330 is also movably connected to the upper end of the guide rod 320. The limiting block 330 can be a circular block structure, and the diameter of the limiting block 330 is larger than the diameter of the guide groove 212. In the initial position, the limiting block 330 abuts against the first material guiding body 210, and the elastic member 310 is in an elastically elongated state between the first material guiding body 210 and the second material guiding body 220. By moving the limiting block 330 in the vertical direction, the vertical distance between the discharge port 221 and the belt 110 in the initial state can be adjusted, which can ensure the use of materials of different sizes and improve the applicability of the device.

[0032] In addition, an elastic buffer pad 213 is provided on the end face of the first material guiding body 210 near the second material guiding body 220. In this embodiment, the elastic buffer pad 213 is provided circumferentially on the lower end face of the first material guiding body 210, which can effectively reduce the direct contact between the second material guiding body 220 and the first material guiding body 210, thereby reducing the likelihood of wear and tear, further protecting the first and second material guiding bodies 210, and improving the service life of the device. Furthermore, the elastic buffer pad 213 can also be provided on the upper end face of the second material guiding body 220, or both the lower end face of the first material guiding body 210 and the upper end face of the second material guiding body 220 can be provided with elastic buffer pads 213. The elastic buffer pad 213 can be made of rubber or silicone.

[0033] In the specific structure of the discharge port 221, a ramp 222 is provided on the side of the discharge port 221 along the transport direction of the belt 110. The ramp 222 includes a first ramp 223 and a second ramp 224. One end of the first ramp 223 and one end of the second ramp 224 are connected, and the inclination directions of the first ramp 223 and the second ramp 224 are opposite. The first ramp 223 is inclined outward from the discharge port 221 along a first direction. Both the first ramp 223 and the second ramp 224 are provided with elastic protective pads 225.

[0034] In this embodiment, as Figure 1As shown, the discharge port 221 is provided with a ramp 222 at one edge in the conveying direction. The ramp 222 includes a second inclined surface 224 facing upwards and a first inclined surface 223 facing downwards in the vertical direction. The lower end of the second inclined surface 224 is connected to the upper end of the first inclined surface 223. The first inclined surface 223 is inclined outwards in the vertical direction from the discharge port 221 toward the conveying direction of the belt 110, so that when the debris moves outwards through the discharge port 221, it can come into contact with the first inclined surface 223, thereby better pushing the second guide body 220 upwards. Furthermore, the inclination direction of the second inclined surface 224 is opposite to that of the first inclined surface 223. The second inclined surface 224 is vertically inclined from the side of the discharge port 221 towards the center of the discharge port 221. This structure effectively avoids the situation where material falling from the guide trough 211 to the discharge port 221 is easily pushed at the first inclined surface 223 due to the inclination direction of the first inclined surface 223. By setting the second inclined surface 224, the material can fall more smoothly from the guide trough 211 to the discharge port 221, and then from the discharge port 221 onto the belt 110. In addition, both the first inclined surface 223 and the second inclined surface 224 are provided with elastic protective pads 225, which effectively prevents the material from abrading the first inclined surface 223 and the second inclined surface 224, protecting the first inclined surface 223 and the second inclined surface 224. The elastic protective pads 225 can be made of rubber or silicone.

[0035] Specifically, an elastic skirt 240 is provided circumferentially at one end of the discharge port 221 near the belt 110, and one end of the elastic skirt 240 is in contact with the belt 110. In this embodiment, an elastic skirt 240 is provided at the edge of the discharge port 221, one end of the elastic skirt 240 is connected circumferentially along the discharge port 221, and the other end is in contact with the belt 110, thereby further reducing the leakage of material from the belt 110 when the material falls from the discharge port 221.

[0036] Furthermore, an elastic telescopic shell 250 is connected between the first material guiding body 210 and the second material guiding body 220. The elastic telescopic shell 250 covers at least the connection between the material guiding channel 211 and the discharge port 221. In this embodiment, an elastic telescopic shell 250 is provided between the first material guiding body 210 and the second material guiding body 220. This elastic telescopic shell 250 can cover the connection between the discharge port 221 and the material guiding channel 211. The elastic telescopic shell 250 can extend and retract accordingly with the movement of the second material guiding body 220, which can effectively reduce the leakage of material from the connection between the discharge port 221 and the material guiding channel 211 during the movement of the second material guiding body 220.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
