[0028] Compared with the prior art, the present invention provides a chainless hopper conveyor device and method, which have the following beneficial effects:

[0029] First, the present invention designs a magnetic adsorption locking mechanism for the hopper. Through the designed linkage structure of the metal cup and the sphere, combined with the plug rod with a transition section, the rapid installation and disassembly of the hopper are realized. This mechanism uses magnetic adsorption unlocking instead of traditional threaded connection, significantly improving the hopper replacement efficiency. The operation process does not require special tools. While ensuring connection stability, it effectively avoids cross-contamination caused by material residues. This design is especially suitable for industry scenarios that require frequent hopper replacement or have strict hygiene standards, greatly improving the convenience and safety of equipment use.

[0030] Second, the present invention designs a multi-stage sleeve lifting mechanism and an angle coordinated adjustment system. Through the combination of the nested sleeve structure and the mechanical linkage device, the dual adjustment capabilities of the conveyor height and angle are realized. This mechanism breaks through the limitations of the traditional fixed structure and can flexibly adjust the conveying height and inclination angle according to the layout of upstream and downstream equipment, significantly improving the adaptability of equipment layout. The unique mechanical drive design ensures a stable and reliable lifting process, especially suitable for complex conveying scenarios with height differences or space limitations, effectively reducing the need for transfer equipment in the material transfer process.

[0031] Third, the present invention designs an L-shaped track opening and closing discharging mechanism. By adopting the design of combining gear-rack transmission with a guide groove, the storage hopper door realizes a composite opening action of first vertical separation and then horizontal movement. This movement track effectively avoids the material jamming problem easily generated by the traditional flap structure, ensures that the discharging port is fully opened while significantly reducing material wall sticking. The unique two-stage opening and closing mechanism is especially suitable for the continuous conveying scenario of powdery and easily caking materials, and realizes fast and precise material release control on the premise of ensuring sealing.

[0032] Fourth, the present invention designs a modular chainless drive system. The split drive layout decouples the conveyor belt operation and angle adjustment functions, and realizes the coordinated operation of the conveying speed and angle through an independent control system. This design abandons the traditional chain drive method, not only improving the power transmission efficiency, but also significantly reducing the running noise and energy consumption. The modular structure makes equipment maintenance more convenient, especially suitable for industrial production environments that require continuous operation. By extending the maintenance interval and reducing the failure rate, the overall reliability of the equipment is effectively improved. Brief Description of the Drawings

[0049] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and other obvious variations can be thought of by those skilled in the art

[0050] Please refer to Figures 1-11 As shown, in the first aspect of the present invention, a chainless bucket conveyor device is proposed, including:

[0051] A chassis 1, on the top of the chassis 1, a controller 101 is provided. In the middle of the chassis 1, four groups of first sleeves 102 are fixedly installed. Inside the first sleeves 102, a second sleeve 103, a third sleeve 104, and a fourth sleeve 105 are slidably connected. On the top of the fourth sleeve 105, a mounting plate 106 is welded. Right above the mounting plate 106, a belt conveyor 108 is provided. On both sides of the belt in the belt conveyor 108, a number of groups of first connecting rods 110 are fixedly installed. On the belt conveyor 108, a number of groups of buckets 111 are provided. At the bottom of the belt conveyor 108, a rotating plate 116 is provided. On the top of the rotating plate 116, a storage hopper 117 is fixedly installed

[0052] An opening and closing mechanism 2, which is installed at the bottom of the rotating plate 116 and is used to control the discharging of the storage hopper 117

[0054] A lifting mechanism 4, which is installed inside the first sleeve 102, the second sleeve 103, the third sleeve 104, and the fourth sleeve 105 and is used to adjust the height of the belt conveyor 108

[0055] Please refer toFigure 3 As shown, the top of the mounting plate 106 is rotatably connected to the mounting frame 107, the belt conveyor 108 is rotatably connected to the inside of the mounting frame 107, the outside of the mounting frame 107 is provided with a first driving motor 109 that drives the belt conveyor 108 to rotate, a driven wheel is fixedly mounted on the short rod at the bottom of the mounting frame 107, an electric motor is provided at the bottom of the mounting plate 106, the output end of the motor is fixedly connected to the driving wheel, and the driving wheel is connected to the driven wheel through a belt.

[0056] Please refer to Figure 2 As shown, mounting parts 114 are welded at the front and rear symmetrical positions of the belt conveyor 108, and a rotating plate 116 is rotatably connected to the inside of the two sets of mounting parts 114. A second driving motor 115 for driving the rotating plate 116 to rotate is arranged on the outer side of the front mounting part 114. A slot is opened through the right side of the top end of the rotating plate 116, and the position of the storage bucket 117 corresponds to the position of the slot.

[0057] Those skilled in the art can understand that the belt conveyor 108 is driven to rotate by the output end of the first drive motor 109, thereby changing the angle of the belt conveyor 108; and the drive wheel is driven to rotate by the output end of the motor, and the driven wheel is driven by the belt to rotate, driving the mounting frame 107 to rotate, thereby driving the belt conveyor 108 to rotate.

[0058] Please refer to Figure 5 and Figure 6 As shown, the opening and closing mechanism 2 includes a rack 205, a movable frame 206 and a pressing plate 208. Two groups of support plates 201 are fixedly connected at left and right symmetrical positions on the front side of the rotating plate 116. The two groups of support plates 201 are rotatably connected to the inside of the rotating rod 202. A gear 203 is fixedly installed in the middle of the outer surface of the rotating rod 202. The gear 203 is meshed with the rack 205. The rack 205 is fixedly connected to the middle of the outer side of the movable frame 206. The outer four corners of the movable frame 206 are rotatably connected to the connecting arms 207. The other end of the arm 207 is rotatably connected to the pressing plate 208. Two groups of connecting plates 209 are welded to the bottom end of the rotating plate 116. An L-shaped groove 210 is penetrated through the connecting plate 209. One group of connecting arms 207 is also provided with a second connecting rod 211 adapted to the L-shaped groove 210, and the second connecting rod 211 is slidably connected to the inside of the L-shaped groove 210. A transmission motor 204 is fixedly installed at the bottom end of one group of support plates 201, and one end of the rotating rod 202 is fixedly connected to the output end of the transmission motor 204.

[0059] Please refer to Figure 5As shown in the figure, a driving motor 204 is fixedly installed at the bottom end of the lower support plate 201. One end of the rotating rod 202 is fixedly connected to the output end of the driving motor 204. A track 212 is fixedly connected to the bottom end of the rotating plate 116. The movable frame 206 is slidably connected to the outer surface of the track 212.

[0060] Those skilled in the art can understand that the materials falling after the tipping bucket 111 in the present invention are all fed into the interior of the storage hopper 117. The output end of the driving motor 204 drives the rotating rod 202 and the gear 203 to rotate integrally. Then, the rack 205 moves to the right, causing the movable frame 206 to move to the right. Due to the provision of the L-shaped groove 210, the connecting arm 207 rotates, causing the pressing plate 208 to first move linearly and disengage from the slot opened at the bottom of the rotating plate 116. The pressing plate 208 moves horizontally to the right, thus exposing the slot at the bottom and pouring out the materials.

[0061] Please refer to Figure 9 and Figure 10 As shown in the figure, the locking mechanism 3 further includes a metal cup 301. The metal cup 301 is slidably connected inside the first connecting rod 110. Three through slots 303 are formed through the outer surface of the metal cup 301. An active block 306 is slidably connected inside the metal cup 301. The outside of the active block 306 is fixedly connected to the inner wall of the first connecting rod 110 through a spring 305. Three spheres 302 are also provided inside the metal cup 301.

[0062] Please refer to Figure 9 、 Figure 10 and Figure 11 As shown in the figure, a first through hole 304 is formed through the middle of one end of the metal cup 301. A second through hole 307 is formed through the middle of the active block 306. Plug rods 112 are fixedly connected to the front and rear sides of the storage hopper 117. A transition section 113 is provided on the plug rod 112.

[0063] Those skilled in the art can understand that when installing the tipping bucket 111, by inserting the insertion rods 112 on both sides into the inner part of the first through holes 304 in the first connecting rods 110 on both sides respectively, the three groups of spheres 302 are pushed outwards, and together with the metal cup 301, they will also move to the left. The spring 305 presses the movable block 306 to the right, driving the spheres 302 to be pressed to the right. The spheres 302 will also be squeezed by the inner wall of the first connecting rod 110 and get stuck at the transition section 113 of the insertion rod 112, thus locking the insertion rod 112 and realizing the fixed installation of the tipping bucket 111. When disassembling it, bring the detachable permanent magnet close to the outside of the first connecting rod, and drive the axial movement of the metal cup through magnetic attraction; or start the electromagnetic device integrated in the belt conveyor frame through the controller to make the coil winding energized to generate axial magnetic attraction. Both methods make the metal cup generate displacement, release the mechanical constraint of the sphere on the transition section of the insertion rod, and realize the quick disassembly of the tipping bucket. When the metal cup 301 moves to the left under the magnetic force of the magnet, there will be enough space for the three groups of spheres 302 to move outwards, unlocking the insertion rod 112, and the insertion rod 112 can be directly pulled out from the inner part of the first connecting rod 110, thus realizing the disassembly of the tipping bucket 111.

[0064] Please refer to Figure 7 and Figure 8 As shown in the figure, the lifting mechanism 4 includes a stepping motor 401, a lead screw 402, a lifting member 406 and a telescopic member 409. The stepping motor 401 is fixedly installed at the inner bottom end of the first sleeve 102. A connecting bar 403 is also fixedly connected to the inner top end of the first sleeve 102. One end of the lead screw 402 is fixedly connected to the output end of the stepping motor 401, and the other end of the lead screw 402 is rotatably connected to the inside of the connecting bar 403. The lifting member 406 is threadedly connected to the outer surface of the lead screw 402. A first fixed shaft is fixedly connected to the inner bottom end of the first sleeve 102. A first rotating arm 404 and a second rotating arm 405 are rotatably connected to the outer surface of the first fixed shaft. And a second fixed shaft is fixedly connected to the inner top end of the fourth sleeve 105. A third rotating arm 407 and a fourth rotating arm 408 are rotatably connected to the outer surface of the second fixed shaft. The two sides of the bottom end of the telescopic member 409 are respectively rotatably connected to the first rotating arm 404 and the second rotating arm 405, and the two sides of the top end of the telescopic member 409 are respectively rotatably connected to the third rotating arm 407 and the fourth rotating arm 408. The lifting member 406 is fixedly connected to the telescopic member 409.

[0065] Please refer to Figure 7 As shown in the figure, limiting grooves 410 are formed on both the second sleeve 103 and the third sleeve 104. A limiting rod 411 is arranged on the telescopic member 409, and the limiting rod 411 is slidably connected to the inside of the limiting groove 410.

[0066] Those skilled in the art can understand that the output end of the stepping motor 401 drives the lead screw 402 to rotate, causing the lifting member 406 to move up and down. When the lifting member 406 moves upward, the telescopic member 409 is in a stretched state, driving the second sleeve 103, the third sleeve 104, and the fourth sleeve 105 to all slide upward. Also, when the lifting member 406 moves downward, the telescopic member 409 is in a retracted state, driving the second sleeve 103, the third sleeve 104, and the fourth sleeve 105 to all slide downward. Therefore, the overall height of the device can be changed, thereby changing the height of the belt conveyor 108; and by setting the cooperation of the limiting rod 411 and the limiting groove 410, the stability of the movement of the telescopic member 409 is improved.

[0067] In the second aspect of the present invention, a method for using the chainless bucket elevator conveying device is proposed, including:

[0068] S1. First, move the device to the designated location. The output end of the first driving motor 109 drives the belt conveyor 108 to rotate, thereby changing the angle of the belt conveyor 108 so that the left end of the belt conveyor 108 is adapted to the discharge end position of the external feeding machine.

[0069] S2. Install the buckets 111 in sequence. By inserting the insertion rods 112 on both sides into the inner parts of the first through holes 304 in the first connecting rods 110 on both sides respectively, the three groups of spheres 302 are pushed outwards, and together with the metal cups 301, they will also move to the left side. The spring 305 presses the movable block 306 to the right side, driving the spheres 302 to be pressed to the right side. The spheres 302 are also squeezed by the inner wall of the first connecting rod 110 and are stuck at the transition section 113 on the insertion rod 112, thereby locking the insertion rod 112 and realizing the fixed installation of the bucket 111.

[0070] S3. During operation, the discharge end of the external feeding machine pours the materials into the interiors of several groups of buckets 111 in sequence. When the buckets 111 pass through the curved position at the right end of the belt conveyor 108, they will turn over and pour the materials into the storage hopper 117.

[0071] S4. Secondly, adjust the height of the storage hopper 117 according to the height of the feeding end of the machine in the next process. The output end of the stepping motor 401 drives the lead screw 402 to rotate, causing the lifting member 406 to move up and down. When the lifting member 406 moves upward, the telescopic member 409 is in a stretched state, driving the second sleeve 103, the third sleeve 104, and the fourth sleeve 105 to all slide upward. Also, when the lifting member 406 moves downward, the telescopic member 409 is in a retracted state, driving the second sleeve 103, the third sleeve 104, and the fourth sleeve 105 to all slide downward. Therefore, the overall height of the device is changed, so that the height of the belt conveyor 108 is adapted to the feeding end of the machine in the next process.

[0072] S5. Next, the output end of the driving motor 204 drives the rotating rod 202 and the gear 203 to rotate as a whole. As a result, the rack 205 moves to the right, causing the movable frame 206 to move to the right. Due to the provision of the L-shaped groove 210, the connecting arm 207 rotates, causing the pressing plate 208 to first move linearly and disengage from the notch opened at the bottom of the rotating plate 116. The pressing plate 208 moves horizontally to the right, thus exposing the notch at the bottom and pouring the material into the feeding end inside the machine in the next process.

[0073] S6. When other materials need to be conveyed, if the inner wall of this batch of rotary buckets 111 adheres to the materials remaining from the previous time, then this batch of rotary buckets 111 can no longer be used. To avoid affecting other materials, it is necessary to disassemble and replace this batch of rotary buckets 111, ensuring the cleanliness and safety of the conveying environment. When disassembling it, bring the detachable permanent magnet close to the outside of the first connecting rod, and drive the metal cup to move axially through magnetic attraction; or start the electromagnetic device integrated in the belt conveyor frame through the controller to energize the coil winding to generate axial magnetic attraction. Both methods cause the metal cup to displace, releasing the mechanical constraint of the sphere on the transition section of the plug rod, realizing the rapid disassembly of the rotary bucket.

[0074] By any of the above methods, the metal cup 301 is magnetically shifted to the left, and there will be enough space for the three groups of spheres 302 to move outwards, unlocking the plug rod 112. The plug rod 112 can be directly pulled out from the inside of the first connecting rod 110, thus realizing the disassembly of the rotary bucket 111.

[0075] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
