Abstract
Description
Technical Field
[0001] This utility model belongs to the field of belt conveyor unloading technology, and in particular relates to a mobile unloading device for belt conveyors. Background Technology
[0002] A belt conveyor is a type of belt transport machine, primarily used for material transport, especially for long-distance material transport. During operation, belt conveyors can transport various types of solid materials, such as powders, crushed materials, and lumps, making them widely used in industries such as mining, grain production, and factory manufacturing.
[0003] In order to unload materials onto the belt conveyor during operation, the existing technology involves fixing an unloading bin that works with the belt conveyor at the feed end. The material is fed into the unloading bin via a method such as a screw conveyor and then guided onto the belt conveyor by the unloading bin.
[0004] However, in actual work processes, such as in grain depot operations, materials are not piled up in a specific area, but are mostly stacked separately (the reason is that if there are too many types of grain in the grain warehouse, the height of the stack in one place is too large, making it difficult to operate and load materials. Therefore, in actual work processes, materials are often stacked in a straight line along the length of the belt conveyor to facilitate loading onto the belt conveyor). As the unloading bins on the existing belt conveyors are fixed, it is necessary to continuously shovel the stacked materials onto the loading area of the belt conveyor using a loader during operation.
[0005] Clearly, this method not only increases the workload of material handling, but also requires a continuous supply of material to the conveyor belt's loading position. Therefore, the workload during operation is substantial.
[0006] Therefore, in actual operation, if the unloading bin on the conveyor belt can be moved flexibly along the conveyor belt to continuously move to the material stacking position, and after the material in one stack is loaded, it can be moved to the position corresponding to the next stacking material area, which not only reduces the operation difficulty and workload of the material loading conveyor belt, but also greatly improves the material loading and transmission efficiency.

[0018] Preferably, the first traction structure includes a first traction motor, and a first traction wheel is fixedly mounted on the output shaft of the first traction motor;
[0019] The first traction wheel is wound with a first steel cable, which is suspended on one side of the mobile unloading bin;
[0020] The second traction structure includes a second traction motor, and a second traction wheel is fixedly mounted on the output shaft of the second traction motor;
[0021] A second steel cable is wound around the second traction wheel, and the second steel cable is suspended on the other side of the mobile unloading hopper.
[0022] Preferably, the belt conveyor frame is fixedly connected with motor mounting brackets for mounting the first traction motor and the second traction motor.
[0023] Preferably, the two sides of the mobile unloading hopper are respectively fixedly connected with hanging rings for suspending the first steel cable and the second steel cable;
[0024] The first and second steel cables are fixedly connected with buckles that are pulled on the hanging rings.
[0025] Preferably, guide ramps are fixedly connected to both sides of the opening of the mobile unloading bin.
[0026] Preferably, the discharge port of the mobile unloading hopper is provided with an adjustable discharge structure, which is used to adjust the discharge distance between the discharge port and the conveyor belt of the belt conveyor.
[0027] Preferably, the adjusting feeding structure includes a fixed cylinder integrally formed on the discharge port of the mobile unloading bin;
[0028] The fixed cylinder is slidably connected to an adjusting sleeve;

[0032] This utility model has the following beneficial effects:
[0033] 1. During the unloading process, the stacked materials are loaded into the mobile unloading bin. After unloading, the mobile unloading bin moves to the position of the adjacent stack. This process is repeated until all material stacks have been loaded and transported.
[0034] This method solves the problem of transporting stacked materials via conveyor belts in a way that minimizes workload, reduces labor intensity, and maximizes transportation efficiency, such as in grain storage or coal depots.
[0035] 2. During operation, the first traction motor drives the first traction wheel to wind up the first steel cable (the first steel cable is wound in the groove of the first traction wheel), while simultaneously, the second traction motor continuously unwinds the second steel cable until the moving unloading bin moves to the location of the next material pile and feeds the material onto the conveyor belt in the same manner. After the last material pile is fed, the moving unloading bin is reset in the reverse manner.
[0036] The above structure enables the mobile unloading bin to be moved according to the location of the material pile, thus avoiding the many drawbacks of traditional belt conveyors where the unloading bin is fixed and cannot be moved. During the material feeding process, the material needs to be continuously piled up and shoveled to the belt conveyor near the unloading bin, resulting in a large workload, high feeding difficulty, and low efficiency.
[0037] 3. By adjusting the feeding structure, the distance between the discharge port of the unloading hopper and the belt can be changed. Depending on the state of the material, such as powder that is prone to generating dust, the discharge position and belt distance can be lowered by adjusting the feeding structure, so that the material falls more smoothly onto the belt and the amount of dust generated can be reduced.

[0049] Example 1
[0050] like Figure 1-6 As shown, a conveyor belt mobile unloading device includes a mobile unloading bin mechanism 2 that rolls onto the conveyor belt frame 1. The mobile unloading bin mechanism 2 includes a mobile unloading bin 21. The main structure of the mobile unloading bin 21 is a fixed structure unloading bin that is currently fixedly installed on existing conveyor belts. The discharge port at the bottom of the mobile unloading bin 21 faces the conveyor belt of the conveyor belt, and a certain distance is maintained between the unloading process and the conveyor belt in order to maintain the unloading process.
[0051] In the course of operation, in order to move the mobile unloading bin 21 along the belt conveyor frame 1 according to the position of the stacked materials, this utility model improves the traditional fixed unloading bin into a mobile unloading bin 21.
[0052] During the unloading process, the stacked materials are loaded into the mobile unloading bin 21. After unloading, the mobile unloading bin 21 moves to the position of the adjacent stacked material pile. This process is repeated until all material piles have been loaded and transported.
[0053] This method solves the problem of transporting stacked materials via conveyor belts in a way that minimizes workload, reduces labor intensity, and maximizes transportation efficiency, such as in grain storage or coal depots.
[0054] Specifically, the mobile unloading bin 21 is fixedly installed with a mobile frame structure that rolls on the belt conveyor frame 1; the mobile frame structure is equipped with track rollers 24.
[0055] Specifically, the movable frame structure includes movable frame beams 23 spaced apart on the left and right sides, and a pair of spaced wheel axles 241 are rotatably connected between the front and rear ends of the movable frame beams 23 on the left and right sides respectively (correspondingly, a bearing bracket 231 rotatably connected to the wheel axles 241 is installed at the bottom of the movable frame beams 23), and the track rollers 24 are fixedly installed at both ends of the wheel axles 241.
[0056] During the movement, the track roller 24 is limited to rolling on the top of the belt conveyor frame 1 (specifically, it is the same as the existing track wheel structure, the track wheel includes a rolling wheel part that rolls on the belt conveyor frame 1, and an integrally formed partition wheel part that blocks the outer side of the rolling wheel part, the partition wheel part is used to prevent the track wheel from derailing from the frame).
[0057] The method for fixing the mobile unloading hopper 21 to the mobile frame crossbeam 23 is as follows:
[0058] A pair of triangular fixed brackets with front-to-back spacing are welded to the side walls on the left and right sides of the mobile unloading hopper 21; a bottom mounting base is welded between the bottom of the fixed brackets, and the bottom mounting base is detachably fixed to the crossbeam 23 of the mobile frame by bolts.
[0059] The purpose is to enable the replacement of the mobile unloading bin 21 in a detachable manner during operation, such as replacing it with a bin with a larger capacity.
[0060] Example 2
[0061] like Figure 1-6 As shown, based on the structure of Embodiment 1, this embodiment, in order to enable the movable unloading bin 21 to move on the conveyor frame 1 and facilitate its movement to the material pile directly opposite the side position, further includes a first traction structure and a second traction structure that pull the movable unloading bin 21 in opposite directions respectively. Specifically, the first traction structure pulls the entire device forward, while the second traction structure cooperates with unwinding the traction cable during the pulling process of the first traction structure. After moving to the last material pile and unloading is completed, the second traction structure pulls the movable unloading bin 21 back to its original position, and correspondingly, the first traction structure cooperates with unwinding the traction cable.
[0062] Specifically, the first traction structure includes a first traction motor 25, on which a first traction wheel is fixedly mounted; a first steel cable 251 is wound on the first traction wheel, and the first steel cable 251 is suspended on the front side of the mobile unloading bin 21.
[0063] Similarly, the second traction structure includes a second traction motor 26, on the output shaft of the second traction motor 26, a second traction wheel is fixedly installed; a second steel cable 261 is wound on the second traction wheel, and the second steel cable 261 is suspended on the rear side of the mobile unloading bin 21.
[0064] The traction motors are fixed as follows: motor mounting brackets for mounting the first traction motor 25 and the second traction motor 26 are fixedly connected to the belt conveyor frame 1.
[0065] The mobile unloading bin 21 is fixedly connected to two sides of the first steel cable 251 and the second steel cable 261 respectively, and the first steel cable 251 and the second steel cable 261 are fixedly connected to the buckles that are attached to the hanging rings 212.
[0066] During operation, the operator can use a screw conveyor, for example, to move the material pile located on the far left (in order to...). Figure 1 (As shown for reference) The material is fed into the mobile unloading bin 21 to complete the unloading. Then, the first traction motor 25 drives the first traction wheel to wind up the first steel cable 251 (the first steel cable 251 is wound in the groove of the first traction wheel). At the same time, the second traction motor 26 cooperates to continuously unwind the second steel cable 261 until the mobile unloading bin 21 moves to the location of the next material pile and feeds the material onto the belt conveyor in the same way.
[0067] Once the last material pile has been loaded, the mobile unloading hopper 21 will be reset in the reverse manner described above.
[0068] The above structure enables the movable unloading bin 21 to be moved according to the location of the material pile, thus avoiding the many drawbacks of traditional belt conveyors where the unloading bin is fixed and cannot be moved. During the material feeding process, the material needs to be continuously piled up and shoveled to the belt conveyor near the unloading bin, resulting in a large workload, high feeding difficulty, and low efficiency.
[0069] Example 3
[0070] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 2, the material is first fed into the mobile unloading bin 21 during the belt conveyor feeding process. Therefore, to facilitate feeding, guide ramps 22 are fixedly connected to the left and right sides of the opening of the mobile unloading bin 21. During operation, the material can be fed into the guide ramps 22 by means of a screw conveyor, and then discharged into the mobile unloading bin 21 by the guiding action of the guide ramps 22. The guide ramps on both sides enable feeding from both sides.
[0071] Example 4
[0072] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 3, the material is fed into the mobile unloading bin 21 and then discharged from the bottom outlet of the mobile unloading bin 21 onto the belt conveyor. In actual operation, when dealing with finely ground materials such as rice and bran, which are dry powders with high fineness and light texture, a large amount of dust falls onto the conveyor belt during discharge. Therefore, in the prior art, the amount of dust can only be reduced by decreasing the discharge speed.
[0073] Therefore, in order to ensure smooth material feeding while appropriately reducing dust (when the distance between the discharge port of the unloading hopper and the belt is too large, the dust from the material falling onto the belt will spread significantly), this invention designs the discharge port of the movable unloading hopper 21 to be adjustable. This allows for a gentler material drop onto the belt, reducing dust generation, especially for finer materials, by lowering the distance between the discharge port and the belt.
[0074] Specifically, the discharge port of the mobile unloading hopper 21 is equipped with an adjustable discharge structure 211, which is used to adjust the discharge distance between the discharge port and the conveyor belt of the belt conveyor.
[0075] Specifically, the adjusting unloading structure 211 includes a fixed cylinder 21111 (in the shape of a cuboid) integrally formed on the discharge port of the mobile unloading bin 21; the fixed cylinder 21111 is slidably connected to an adjusting sleeve 2112.
[0076] When the material is discharged from the outlet of the mobile unloading bin 21, the material falls too far into the air, resulting in serious dust dispersion. The adjustment sleeve 2112 is adjusted so that the gap between the bottom of the adjustment sleeve 2112 and the belt of the conveyor is reduced (after adjustment, it is still necessary to ensure that the material can be carried away by the belt of the conveyor normally and will not "accumulate").
[0077] Specifically, the adjusting sleeve 2112 and the fixed cylinder 21111 are positioned after adjustment through several locking structures. Specifically, the adjusting sleeve 2112 and the fixed cylinder 21111 are both rectangular and are adjusted through locking structures on the left and right side walls.
[0078] Specifically, the locking structure includes a pair of long adjusting slots spaced apart on one side wall of the adjusting sleeve 2112; correspondingly, a positioning screw 2113 is fixedly connected to the fixed cylinder 21111, which passes vertically through the long adjusting slots, and the positioning screw 2113 is threadedly connected to the nut of the positioning adjusting sleeve 2112.
[0079] After loosening all nuts, slide down the adjusting sleeve 2112 and observe the material transmission status onto the belt. While ensuring smooth material transmission, minimize the gap between the adjusting sleeve 2112 and the belt. Consequently, during material feeding, the material discharge stroke after exiting the adjusting sleeve 2112 will be reduced, thus initially preventing a large amount of dust from spreading into the air during the material discharge stroke.
[0080] Secondly, when the distance between the adjusting sleeve 2112 and the belt is reduced, the material falls more gently on the belt, and thus the amount of dust generated is greatly reduced (conversely, if the distance between the material outlet and the belt height is too large, the kinetic energy of the material falling on the belt is greater, and more dust is generated).
[0081] At the same time, after reducing the gap between the adjusting sleeve 2112 and the belt, when the material falls into the belt, dust is generated. As the material falls continuously onto the belt, it will be moderately "buried and settled" by the continuously fed material, further reducing the amount of dust.
[0082] After adjustment, the nut presses against the positioning adjusting sleeve 2112. In actual operation, the adjusting sleeve 2112 can be made of lightweight aluminum alloy. Since the adjusting sleeve 2112 is only used to guide the material, the load during the feeding process is not high. The nut pressing positioning method can stably position the adjusting sleeve 2112 and keep it from loosening and sliding.
[0083] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
