Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ton bag transfer technology, and relates to a hoisting and conveying device, particularly an integrated transfer equipment for hoisting, conveying and unloading ton bags. Background Technology
[0002] A ton bag, also known as a bulk packaging container, is a large-capacity packaging container mainly used for loading and transporting bulk materials such as grains and chemical raw materials. Made of materials such as polypropylene, it has advantages such as moisture resistance, dust resistance, radiation resistance, and high structural strength, and is widely used in various industries.
[0003] Currently, the transfer of ton bags is usually carried out automatically by hoisting and conveying devices. However, existing hoisting and conveying devices have poor stability during the filling and transportation of ton bags, are inconvenient to assemble and disassemble, and are prone to generating dust during filling and unloading.
[0004] Based on this, we propose an integrated transfer equipment for ton bag hoisting, conveying, and unloading, which is more stable during ton bag filling and transportation, and can quickly transfer and hoist ton bags. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing an integrated transfer equipment for ton bag hoisting, conveying, and unloading. The technical problem this utility model aims to solve is: how to achieve stable filling, rapid transfer, and hoisting of ton bags with higher transfer efficiency.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] An integrated transfer equipment for hoisting, conveying, and unloading ton bags includes a traveling conveyor line, a transfer conveyor line, and a lifting and filling mechanism. The discharge end of the transfer conveyor line is located inside the traveling conveyor line, and the lifting and filling mechanism is located on the left side of the traveling conveyor line. The transfer conveyor line passes through the interior of the lifting and filling mechanism. The lifting and filling mechanism is connected to an external vacuum cleaner and an external storage bin. An intelligent transfer vehicle is provided on the transfer conveyor line, and two gantry cranes are provided on the traveling conveyor line. A moving mechanism is provided between the two gantry cranes. An auxiliary guiding mechanism and a hoisting mechanism are provided on the moving mechanism. A telescopic connecting mechanism is provided at the lower end of the hoisting mechanism. The positions of the auxiliary guiding mechanism, the hoisting mechanism, and the telescopic connecting mechanism correspond to each other from top to bottom.
[0008] The working principle of this utility model is as follows: the transport vehicle moves to the designated position, and then the staff hangs the hanging ring on the ton bag on the intelligent transfer vehicle. The intelligent transfer vehicle is connected and locked to the ton bag. After locking, the intelligent transfer vehicle moves the ton bag to the bottom of the lifting and filling mechanism. The lifting and filling mechanism moves and fills the ton bag. During the filling process, dust is sucked up to ensure a clean environment. After filling is completed, the staff seals the ton bag. The lifting and filling mechanism can suck up dust when the ton bag is unloaded to ensure a clean environment.
[0009] The intelligent transfer vehicle moves the ton bag via the transfer conveyor line to the discharge end of the line, which is located inside the overhead conveyor line. Two gantry cranes drive the moving mechanism to move and adjust it so that the lifting mechanism is directly above the ton bag. The moving mechanism then moves the lifting mechanism down a certain distance, and the telescopic connecting mechanism is adjusted so that it passes through the lifting lug of the ton bag and inserts into the lifting mechanism, thus locking the lifting mechanism to the ton bag. The intelligent transfer vehicle then releases the connection lock with the ton bag, and the moving mechanism slowly raises the lifting mechanism, thereby slowly raising the ton bag a certain distance until it is completely detached from the intelligent transfer vehicle. The two gantry cranes then move the moving mechanism forward, thereby raising the ton bag towards... The two gantry cranes move forward slowly, accelerating to a certain speed and then moving forward at a constant speed. During the slow acceleration, the auxiliary guide mechanism slowly descends to reduce the swaying caused by the inertia of the ton bag. After moving at a constant speed, the auxiliary guide mechanism resets. When approaching the transport vehicle, the two gantry cranes slowly decelerate. During the slow deceleration, the auxiliary guide mechanism slowly descends to reduce the swaying caused by the inertia of the ton bag. After reaching the designated position, the auxiliary guide mechanism resets, the two gantry cranes stop, and the moving mechanism drives the lifting mechanism to move down a certain distance, placing the ton bag inside the transport vehicle. The telescopic connection mechanism is adjusted to release the connection lock between the lifting mechanism and the ton bag. The moving mechanism drives the lifting mechanism to reset, and the two gantry cranes drive the moving mechanism to reset.
[0010] The intelligent transfer vehicle includes a transfer vehicle body, which is set on the transfer conveyor line. A fixed frame is fixed on the transfer vehicle body. U-shaped hooks are fixed at the four corners of the fixed frame. Four electric push rods are fixed on the top of the fixed frame, and the positions of the electric push rods correspond to the positions of the U-shaped hooks.
[0011] Using the above structure, the hanging ring on the ton bag is hung on the U-shaped hook. The electric push rod extends and cooperates with the U-shaped claw of the U-shaped hook to form a sealed ring, so that the hanging ring is located in the ring, thus realizing the connection between the U-shaped hook and the ton bag.
[0012] The moving mechanism includes a moving guide rail, on which a moving slide is driven. A drive motor is fixed to the upper end of the moving slide. Four clearance openings are provided on the moving slide. Four parallel hoisting and unwinding drums are rotatably mounted on the upper end of the moving slide. The positions of the four hoisting and unwinding drums are circumferentially distributed. The positions of the clearance openings match the positions of the hoisting and unwinding drums, and the clearance openings are all located directly below the corresponding hoisting and unwinding drums. The axes of the front and rear hoisting and unwinding drums are collinear, and the rotating shafts of the front and rear hoisting and unwinding drums are connected by a connecting shaft. The output shaft of the drive motor is connected to the rotating shaft of the left hoisting and unwinding drum by a sprocket pair one. The rotating shaft of the left hoisting and unwinding drum is connected to the connecting shaft by a sprocket pair two. The connecting shaft is connected to the rotating shaft of the right hoisting and unwinding drum by a sprocket pair three. Hoisting steel ropes are wound on the hoisting and unwinding drums. The lower ends of the four hoisting steel ropes form a square, and the ends of the four hoisting steel ropes are located at the four apex corners of the square.
[0013] With the above structure, the moving guide rail drives the moving slide to move directly above the ton bag. The output shaft of the drive motor drives the rotating shaft of the left hoisting winding drum to rotate synchronously through the first sprocket pair. The rotating shaft of the left hoisting winding drum drives the connecting shaft to rotate synchronously through the second sprocket pair. The connecting shaft drives the rotating shafts of the front and rear hoisting winding drums to rotate synchronously. The connecting shaft drives the rotating shaft of the right hoisting winding drum to rotate synchronously through the third sprocket pair. Thus, the four hoisting winding drums rotate synchronously, which synchronously and slowly lowers and raises the hoisting steel rope wound on the hoisting winding drums. The clearance facilitates the movement of the hoisting steel rope.
[0014] The hoisting mechanism includes a hoisting fixing plate. The upper end of the hoisting fixing plate is fixedly connected to the lower ends of four hoisting steel ropes. Each of the four lower corners of the hoisting fixing plate is fixed with an inverted U-shaped locking groove plate. The position of the locking groove plate corresponds to the position of the hanging ring on the ton bag. The locking groove plate has through holes inside.
[0015] With the above structure, the hoisting steel rope descends, causing the locking groove plate to descend as well, so that the hanging ring on the ton bag is located inside the locking groove plate, and the through hole inside the locking groove plate is located inside the hanging ring.
[0016] The auxiliary guiding mechanism includes a guide plate, two fixed plates, and four guide pulley groups. The two fixed plates are symmetrically fixed on both sides of the movable slide. An electric lead screw is fixed on one of the fixed plates. One side of the guide plate is fixedly connected to the sliding block of the electric lead screw, and the other side of the guide plate is slidably connected to the other fixed plate. Four through holes are opened at corresponding positions on the guide plate, and bearing seats are fixed in the through holes. A hollow shaft is fixed at the bottom of the guide pulley group, and the inside of the bearing seat is fixedly connected to the hollow shaft. The position of the guide pulley group corresponds to the position of the connection between the hoisting fixed plate and the hoisting steel rope. The hoisting steel rope passes through the guide pulley group at the corresponding position and connects to the hoisting fixed plate. The hoisting steel rope is in a vertical state between the guide pulley group and the hoisting fixed plate.
[0017] With the above structure, the electric lead screw drives the guide plate to move up and down. Through the cooperation of the hoisting steel rope and the guide pulley block, the hoisting steel rope is always kept in a vertical state between the guide pulley block and the hoisting fixed plate, reducing the impact of the change in the output position of the hoisting steel rope on the stability of the hoisting fixed plate due to the hoisting drum being lowered and retracted.
[0018] The telescopic connection mechanism includes a connecting plate, which is fixed to the lower side of the hoisting fixing plate. Two symmetrical I-beam fixing members are fixed to the lower side of the connecting plate. Racks are slidably provided on both the upper and lower sides of the I-beam fixing members. A limit rod is fixed to one end of the rack, and a connecting locking pin is fixed to the other end of the rack. The upper connecting locking pin is Z-shaped, and the lower connecting locking pin is cylindrical. The outer ends of the two connecting locking pins are in opposite directions and their axes coincide. The outer ends of the connecting locking pins correspond to the specifications and positions of the through holes inside the locking slot plate. A second drive motor is fixed to the outer side of one of the I-beam fixing members. The output shaft of the second drive motor is rotatably mounted on the two I-beam fixing members. Two drive gears are fixed on the output shaft of the second drive motor. The drive gears are rotatably mounted on the inner side of the corresponding I-beam fixing members. Each drive gear meshes with the corresponding upper and lower racks.
[0019] With the above structure, the hoisting and fixing plate is lowered so that the through hole inside the hoisting and fixing plate is located inside the hanging ring on the ton bag, and the through hole inside the locking slot plate is located inside the hanging ring. The second drive motor drives the drive gear to rotate in the forward direction, thereby driving the connecting locking pin to extend out, so that the connecting locking pin is inserted into the through hole inside the locking slot plate through the hanging ring on the ton bag, thereby realizing the connection of the locking slot plate to the ton bag.
[0020] When the ton bag reaches the designated position, the second drive motor drives the drive gear to rotate in the opposite direction, causing the connecting locking pin to retract and thus disconnecting the locking slot plate from the ton bag.
[0021] The limit rod is used to prevent the drive gear from rotating excessively and the rack from disengaging from the drive gear.
[0022] The lifting and filling mechanism includes an electric lifting frame, with a feeding hopper fixed between two lifting slides of the electric lifting frame. The feeding hopper is located inside the electric lifting frame. A sliding receiving pipe is fixed at the upper end of the feeding hopper, and a feeding pipe is sleeved on the upper end of the sliding receiving pipe. The feeding pipe is connected to an external storage bin. A discharge port is provided at the lower end of the feeding hopper, and a dust suction hood is provided at the lower outer side of the discharge port. Dust suction ports are provided around the upper end of the dust suction hood, and the dust suction ports are connected to the inside of the dust suction hood and to an external vacuum cleaner.
[0023] Using the above structure, during ton bag filling, the intelligent transfer vehicle moves the ton bag on it to directly below the discharge port and stops. Then, the electric lifting frame moves the feeding hopper downward through two lifting slides. At this time, the sliding receiving pipe slides on the feeding pipe, and the feeding hopper extends into the ton bag. The dust collection hood covers the upper part of the ton bag opening. Then, the external storage bin discharges material. The discharged material enters the sliding receiving pipe from the feeding pipe and then enters the feeding hopper from the sliding receiving pipe. It is then output from the discharge port through the feeding hopper and enters the ton bag from the discharge port. During material discharge, the external vacuum cleaner sucks up the dust generated during material discharge and filling through the dust collection port. The dust collection hood is used to limit the dust dispersion and ensure the dust collection effect.
[0024] Compared with existing technologies, this integrated transfer equipment for hoisting, conveying, and unloading tonnes has the following advantages:
[0025] By cooperating with the electric push rod and the U-shaped hook, the electric push rod extends and forms a sealed ring with the U-shaped claw of the U-shaped hook, so that the intelligent transfer vehicle can connect and lock the ton bag, preventing the ton bag from falling off during the filling process and improving the filling stability.
[0026] 2. The lifting and filling mechanism works in conjunction with the intelligent transfer vehicle to carry out lifting and filling, and sucks away the dust generated during filling and unloading to avoid environmental pollution and keep the working environment clean.
[0027] 3. The moving mechanism enables the four hoisting drums to rise and fall synchronously, improving the stability during the transfer of ton bags;
[0028] 4. By using an auxiliary guiding mechanism, the hoisting steel rope is kept vertical between the guide pulley block and the hoisting fixing plate, reducing the impact of changes in the output position of the hoisting steel rope during the lowering and raising of the hoisting drum on the stability of the hoisting fixing plate.
[0029] 5. Through the cooperation of the moving mechanism, the auxiliary guiding mechanism and the hoisting mechanism, the auxiliary guiding mechanism moves up and down, changing the vertical distance between the moving mechanism, the auxiliary guiding mechanism and the hoisting mechanism, reducing the swaying caused by the inertia of the ton bag, and improving the safety and stability of the ton bag during transportation.
[0030] 6. Through the telescopic connection mechanism and the hoisting mechanism, the connecting locking pin is inserted into the through hole inside the locking slot plate through the hanging ring on the ton bag, so as to realize the stable connection between the hoisting mechanism and the ton bag, which facilitates disassembly, hoisting and transportation.

Detailed Implementation
[0038] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0039] like Figures 1-6As shown, this integrated transfer equipment for hoisting, conveying, and unloading ton bags includes a traveling conveyor line 2, a transfer conveyor line 3, and a lifting and filling mechanism 11. The discharge end of the transfer conveyor line 3 is located inside the traveling conveyor line 2, and the lifting and filling mechanism 11 is located on the left side of the traveling conveyor line 2. The transfer conveyor line 3 passes through the interior of the lifting and filling mechanism 11. The lifting and filling mechanism 11 is connected to an external vacuum cleaner and an external storage bin. An intelligent transfer vehicle 4 is installed on the transfer conveyor line 3, and two gantry cranes 5 are installed on the traveling conveyor line 2. A moving mechanism 6 is installed between the two gantry cranes 5. An auxiliary guiding mechanism 7 and a hoisting mechanism 9 are installed on the moving mechanism 6. A telescopic connecting mechanism 8 is installed at the lower end of the hoisting mechanism 9. The positions of the auxiliary guiding mechanism 7, the hoisting mechanism 9, and the telescopic connecting mechanism 8 correspond to each other from top to bottom.
[0040] In this embodiment, the transport vehicle 1 moves to the designated position, and then the staff hangs the hanging ring on the ton bag 10 on the intelligent transfer vehicle 4. The intelligent transfer vehicle 4 is connected and locked to the ton bag 10. After locking, the intelligent transfer vehicle 4 moves the ton bag 10 to directly below the lifting and filling mechanism 11. The lifting and filling mechanism 11 moves and fills the ton bag 10, and sucks up the dust during the filling process. After the filling is completed, the staff seals the ton bag 10. The lifting and filling mechanism 11 can suck up the dust when the ton bag is unloaded to ensure a clean environment.
[0041] The intelligent transfer vehicle 4 moves the ton bag 10 to the discharge end of the transfer conveyor line 3. The discharge end of the transfer conveyor line 3 is located inside the overhead transport line 2. Two gantry cranes 5 drive the moving mechanism 6 to move and adjust the moving mechanism 6 so that the lifting mechanism 9 is directly above the ton bag 10. The moving mechanism 6 drives the lifting mechanism 9 to move down a certain distance. The telescopic connecting mechanism 8 is adjusted so that it passes through the lifting lug of the ton bag 10 and inserts into the interior of the lifting mechanism 9, thus locking the connection between the lifting mechanism 9 and the ton bag 10. The intelligent transfer vehicle 4 releases the connection lock with the ton bag 10. The moving mechanism 6 drives the lifting mechanism 9 to slowly rise, thereby slowly raising the ton bag 10 a certain distance, so that the ton bag 10 is completely detached from the intelligent transfer vehicle 4. The two gantry cranes 5 drive the moving mechanism 6 to move forward, thereby lifting the ton bag 10 to the bottom. The moving ton bag 10 moves forward. The two gantry cranes 5 slowly accelerate to a certain speed and then move forward at a constant speed. During the slow acceleration, the auxiliary guide mechanism 7 slowly descends to reduce the swaying caused by the inertia of the ton bag 10. After moving at a constant speed, the auxiliary guide mechanism 7 resets. When approaching the transport vehicle 1, the two gantry cranes 5 slowly decelerate. During the slow deceleration, the auxiliary guide mechanism 7 slowly descends to reduce the swaying caused by the inertia of the ton bag 10. After reaching the designated position, the auxiliary guide mechanism 7 resets, the two gantry cranes 5 stop, and the moving mechanism 6 drives the hoisting mechanism 9 to move down a certain distance so that the ton bag 10 is placed in the transport vehicle 1. The telescopic connection mechanism 8 is adjusted to release the connection lock between the hoisting mechanism 9 and the ton bag 10. The moving mechanism 6 drives the hoisting mechanism 9 to reset, and the two gantry cranes 5 drive the moving mechanism 6 to reset.
[0042] The intelligent transfer vehicle 4 includes a transfer vehicle body 401, which is set on the transfer conveyor line 3. A fixed frame 402 is fixed on the transfer vehicle body 401. U-shaped hooks 403 are fixed at the four corners of the fixed frame 402. Four electric push rods 404 are fixed on the top of the fixed frame 402, and the positions of the electric push rods 404 and the U-shaped hooks 403 correspond to each other.
[0043] In this embodiment, the hanging ring on the ton bag 10 is hung on the U-shaped hook 403, the electric push rod 404 extends and cooperates with the U-shaped claw of the U-shaped hook 403 to form a sealed ring, so that the hanging ring is located in the ring, thereby realizing the connection and locking of the intelligent transfer vehicle 4 to the ton bag 10.
[0044] The moving mechanism 6 includes a moving guide rail 601, on which a moving slide 602 is driven. A drive motor 605 is fixed to the upper end of the moving slide 602. The moving slide 602 has four clearance openings 607. Four parallel hoisting and unloading drums 604 are rotatably mounted on the upper end of the moving slide 602, and the positions of the four hoisting and unloading drums 604 are circumferentially distributed. The positions of the clearance openings 607 match the positions of the hoisting and unloading drums 604, and each clearance opening 607 is located directly below the corresponding hoisting and unloading drum 604. The axes of the front and rear hoisting and unloading drums 604 are collinear, and the front and rear... The rotating shaft of the hoisting winding drum 604 is driven by the connecting shaft 608. The output shaft of the drive motor 605 and the rotating shaft of the left hoisting winding drum 604 are driven by the sprocket pair 603. The rotating shaft of the left hoisting winding drum 604 and the connecting shaft 608 are driven by the sprocket pair 609. The connecting shaft 608 and the rotating shaft of the right hoisting winding drum 604 are driven by the sprocket pair 610. Hoisting steel ropes 606 are wound on the hoisting winding drum 604. The lower ends of the four hoisting steel ropes 606 form a square, and the ends of the four hoisting steel ropes 606 are located at the four vertices of the square.
[0045] In this embodiment, the movable guide rail 601 drives the movable slide 602 to move directly above the ton bag 10. The output shaft of the drive motor 605 drives the rotating shaft of the left hoisting winding drum 604 to rotate synchronously through the sprocket pair 603. The rotating shaft of the left hoisting winding drum 604 drives the connecting shaft 608 to rotate synchronously through the sprocket pair 609. The connecting shaft 608 drives the rotating shafts of the front and rear hoisting winding drums 604 to rotate synchronously. The connecting shaft 608 drives the rotating shaft of the right hoisting winding drum 604 to rotate synchronously through the sprocket pair 610. Thus, the four hoisting winding drums 604 rotate synchronously, and the hoisting steel rope 606 wound on the hoisting winding drums 604 is slowly lowered and retracted synchronously. The clearance opening 607 facilitates the movement of the hoisting steel rope 606.
[0046] The hoisting mechanism 9 includes a hoisting fixing plate 901. The upper end of the hoisting fixing plate 901 is fixedly connected to the lower ends of four hoisting steel ropes 606. At each of the four corners of the lower end of the hoisting fixing plate 901, there is an inverted U-shaped locking groove plate 902. The position of the locking groove plate 902 corresponds to the position of the hanging ring on the ton bag 10. The locking groove plate 902 has through holes inside.
[0047] In this embodiment, the hoisting steel rope 606 descends, causing the locking groove plate 902 to descend, so that the hanging ring on the ton bag 10 is located inside the locking groove plate 902, and the through hole inside the locking groove plate 902 is located inside the hanging ring.
[0048] The auxiliary guiding mechanism 7 includes a guide plate 703, two fixed plates 701, and four guide pulley groups 704. The two fixed plates 701 are symmetrically fixed on both sides of the movable slide block 602. An electric lead screw 702 is fixed on one of the fixed plates 701. One side of the guide plate 703 is fixedly connected to the sliding block of the electric lead screw 702, and the other side of the guide plate 703 is slidably connected to the other fixed plate 701. Four through holes are opened at corresponding positions on the guide plate 703, and bearing seats are fixed in the through holes. A hollow shaft is fixed at the bottom of the guide pulley group 704, and the bearing seats are fixedly connected to the hollow shaft. The position of the guide pulley group 704 corresponds to the position of the connection between the hoisting fixed plate 901 and the hoisting steel rope 606. The hoisting steel rope 606 passes through the guide pulley group 704 at the corresponding position and connects to the hoisting fixed plate 901. The hoisting steel rope 606 is in a vertical state between the guide pulley group 704 and the hoisting fixed plate 901.
[0049] In this embodiment, the electric lead screw 702 drives the guide plate 703 to move up and down. Through the cooperation of the hoisting steel rope 606 and the guide pulley block 704, the hoisting steel rope 606 is always kept in a vertical state between the guide pulley block 704 and the hoisting fixed plate 901, reducing the impact of the change in the output position of the hoisting steel rope 606 on the stability of the hoisting fixed plate 901 when the hoisting unwinding drum 604 is lowered and retracted.
[0050] The telescopic connection mechanism 8 includes a connecting plate 801, which is fixed to the lower side of the hoisting fixing plate 901. Two symmetrical I-beam fixing members 802 are fixed to the lower side of the connecting plate 801. Racks 803 are slidably provided on both the upper and lower sides of the I-beam fixing members 802. A limit rod 806 is fixed to one end of each rack 803, and a connecting locking pin 807 is fixed to the other end. The upper connecting locking pin 807 is Z-shaped, and the lower connecting locking pin 807 is cylindrical. The outer ends of the two connecting locking pins 807 face opposite directions. Furthermore, the axes coincide, and the outer end of the connecting locking pin 807 corresponds to the specifications and position of the through hole inside the locking slot plate 902. A second drive motor 805 is fixed on the outer side of one of the I-beam fixing parts 802. The output shaft of the second drive motor 805 is rotatably mounted on the two I-beam fixing parts 802. Two drive gears 804 are fixed on the output shaft of the second drive motor 805. The drive gears 804 are rotatably mounted on the inner side of the corresponding I-beam fixing parts 802. The drive gear 804 on each side meshes with the corresponding upper and lower racks 803.
[0051] In this embodiment, the hoisting fixing plate 901 is lowered so that the internal through hole of the hoisting fixing plate 901 is located inside the hanging ring on the ton bag 10, and the internal through hole of the locking groove plate 902 is located inside the hanging ring. The drive motor 805 drives the drive gear 804 to rotate in the forward direction, thereby causing the connecting locking pin 807 to extend out, so that the connecting locking pin 807 is inserted into the internal through hole of the locking groove plate 902 through the hanging ring on the ton bag 10, thereby realizing the connection of the locking groove plate 902 to the ton bag 10.
[0052] When the ton bag 10 reaches the designated position, the drive motor 805 drives the drive gear 804 to rotate in the opposite direction, causing the connecting locking pin 807 to retract, thereby disconnecting the locking slot plate 902 from the ton bag 10.
[0053] The limit rod 806 is used to prevent the drive gear 804 from rotating excessively and the rack 803 from disengaging from the drive gear 804.
[0054] The lifting and filling mechanism includes an electric lifting frame 1103. A feeding hopper 1107 is fixed between two lifting slides of the electric lifting frame 1103. The feeding hopper 1107 is located inside the electric lifting frame 1103. A sliding receiving pipe 1102 is fixed at the upper end of the feeding hopper 1107. A feeding pipe 1101 is sleeved on the upper end of the sliding receiving pipe 1102. The feeding pipe 1101 is connected to an external storage bin. A discharge port 1105 is provided at the lower end of the feeding hopper 1107. A dust suction hood 1104 is provided at the lower outer side of the discharge port 1105. Dust suction ports 1106 are provided around the upper end of the dust suction hood 1104. The dust suction ports 1106 are connected to the inside of the dust suction hood 1104 and are all connected to an external vacuum cleaner.
[0055] In this embodiment, during the filling of the ton bag 10, the intelligent transfer vehicle 4 moves the ton bag 10 on it to directly below the discharge port 1105 and stops. Then, the electric lifting frame 1103 drives the feeding hopper 1107 downward through two lifting slides. At this time, the sliding receiving pipe 1102 slides on the feeding pipe 1101, and the feeding hopper 1107 extends into the ton bag 10. The dust suction hood 1104 covers the upper part of the opening of the ton bag 10. Then, the external storage bin discharges the material. The discharged material enters the sliding receiving pipe 1102 from the feeding pipe 1101 and enters the feeding hopper 1107 from the sliding receiving pipe 1102. It is then output from the discharge port 1105 through the feeding hopper 1107 and enters the ton bag 10 from the discharge port 1105. During the discharge, the external vacuum cleaner sucks up the dust generated during the discharge and filling through the dust suction port 1106. The dust suction hood 1104 is used to limit the dust dispersion and ensure the dust suction effect.
[0056] The working principle of this utility model is as follows: The transport vehicle 1 moves to the designated position, and then the staff hangs the hanging ring on the ton bag 10 on the U-shaped hook 403. The electric push rod 404 extends and cooperates with the U-shaped claw of the U-shaped hook 403 to form a sealed ring, so that the hanging ring is located in the ring, realizing the connection and locking between the U-shaped hook 403 and the ton bag 10. After locking, the transport vehicle body 401 drives the ton bag 10 to move directly below the lifting and filling mechanism 11. The lifting and filling mechanism 11 moves and fills the ton bag 10. During the filling process, dust is sucked up. That is, when the ton bag 10 is being filled, the intelligent transport vehicle 4 drives the ton bag 10 on it to move directly below the discharge port 1105 and stops. Then the electric lifting frame 1103 moves through two lifting slides. The feeding hopper 1107 moves downward, at which time the sliding receiving pipe 1102 slides on the feeding pipe 1101, the feeding hopper 1107 extends into the ton bag 10, and the dust hood 1104 covers the upper part of the opening of the ton bag 10. Then the external storage bin discharges the material, and the discharged material enters the sliding receiving pipe 1102 from the feeding pipe 1101 and enters the feeding hopper 1107 from the sliding receiving pipe 1102. It is then output from the discharge port 1105 through the feeding hopper 1107 and enters the ton bag 10 from the discharge port 1105. When discharging the material, the external vacuum cleaner sucks up the dust generated during the discharging and filling process through the dust suction port 1106. The dust suction hood 1104 is used to limit the dust dispersion and ensure a clean environment. After filling is completed, the staff seals the ton bag 10.
[0057] The transfer vehicle body 401 moves the ton bag 10 to the discharge end of the transfer conveyor line 3 via the transfer conveyor line 3. Two gantry cranes 5 drive the moving guide rail 601 to move, which in turn moves the moving slide 602 directly above the ton bag 10. The output shaft of the drive motor 605 drives the rotating shaft of the left lifting winding drum 604 to rotate synchronously via the first sprocket pair 603. The rotating shaft of the left lifting winding drum 604 drives the connecting shaft 608 to rotate synchronously via the second sprocket pair 609. The connecting shaft 608 drives the rotating shafts of the front and rear lifting winding drums 604 to rotate synchronously. The connecting shaft 608 drives the rotating shaft of the right lifting winding drum 604 to rotate synchronously via the third sprocket pair 610, thus causing all four lifting winding drums 604 to rotate synchronously, winding the winding drum... Simultaneously and slowly lowering the lifting steel rope 606 wound on the lifting drum 604, the lifting steel rope 606 wound on the lifting drum 604 is slowly lowered a certain distance, so that the hanging ring on the ton bag 10 is located inside the locking groove plate 902. The through hole inside the locking groove plate 902 is located inside the hanging ring. The second drive motor 805 drives the drive gear 804 to rotate in the forward direction, thereby causing the connecting locking pin 807 to extend. The connecting locking pin 807 is inserted into the through hole inside the locking groove plate 902 through the hanging ring on the ton bag 10, realizing the connection and locking between the locking groove plate 902 and the ton bag 10. The electric push rod 404 is retracted, releasing the connection and locking between the U-shaped hook 403 and the ton bag 10. The output shaft of the first drive motor 605 drives the left side of the lifting machine through the first sprocket pair 603. The shafts of the unwinding drums 604 rotate synchronously. The shaft of the left unwinding drum 604 drives the connecting shaft 608 to rotate synchronously via sprocket pair 2 609. The connecting shaft 608 drives the shafts of the front and rear unwinding drums 604 to rotate synchronously. The connecting shaft 608 drives the shaft of the right unwinding drum 604 to rotate synchronously via sprocket pair 3 610. This causes all four unwinding drums 604 to rotate synchronously, slowly and synchronously retracting the lifting steel rope 606 wound on the unwinding drums 604. The lifting steel rope 606 wound on the four unwinding drums 604 is slowly retracted a certain distance, thereby causing the ton bag 10 to slowly rise a certain distance, so that the ton bag 10 is completely detached from the intelligent transfer vehicle 4. The two gantry cranes 5 drive the moving guide rail 601 to move forward. This causes the ton bag 10 to move forward. The two gantry cranes 5 slowly accelerate to a certain speed and then move forward at a constant speed. During this slow acceleration, the electric lead screw 702 drives the guide plate 703 to slowly descend, reducing the vertical distance between the auxiliary guide mechanism 7 and the hoisting mechanism 9 to minimize the swaying caused by the inertia of the ton bag 10. After moving at a constant speed, the electric lead screw 702 drives the guide plate 703 to reset. As they approach the transport vehicle 1, the two gantry cranes 5 slowly decelerate. During this slow deceleration, the auxiliary guide mechanism 7 repeats the above actions, and after reaching the designated position, the auxiliary guide mechanism 7 resets, and the two gantry cranes 5 stop. The output shaft of the drive motor 605 drives the rotating shaft of the left hoisting unwinding drum 604 to rotate synchronously via the sprocket pair 603.The rotating shaft of the left-side hoisting drum 604 drives the connecting shaft 608 to rotate synchronously via sprocket pair 2 609. The connecting shaft 608 drives the rotating shafts of the front and rear hoisting drums 604 to rotate synchronously. The connecting shaft 608 drives the rotating shaft of the right-side hoisting drum 604 to rotate synchronously via sprocket pair 3 610. This causes all four hoisting drums 604 to rotate synchronously, slowly lowering the hoisting steel rope 606 wound on the hoisting drums 604. The hoisting steel rope 606 wound on the hoisting drums 604 is slowly lowered a certain distance. The ton bag 10 is placed inside the transport vehicle 1. When the ton bag 10 reaches the designated position, the drive motor 805 drives the drive gear 804 to rotate in the opposite direction, causing the connecting locking pin 807 to retract and releasing the locking slot plate 902 from the ton bag 10. The moving mechanism 6 drives the hoisting mechanism 9 to reset, and the two gantry cranes 5 drive the moving mechanism 6 to reset. When unloading the ton bag, the unloading is generally carried out by pouring and puncturing the bottom. Dust is easily generated during unloading, which can be extracted by the dust suction hood 1104 to ensure a clean working environment.
[0058] In summary, by cooperating with the electric push rod 404 and the U-shaped hook 403, the electric push rod 404 extends and forms a sealed ring with the U-shaped claw of the U-shaped hook 403, thereby enabling the intelligent transfer vehicle 4 to connect and lock the ton bag 10, preventing the ton bag 10 from falling off during the filling process and improving the filling stability.
[0059] The lifting and filling mechanism 11 works in conjunction with the intelligent transfer vehicle 4 to perform lifting and filling, and sucks away the dust generated during filling and unloading to avoid polluting the environment and keep the working environment clean.
[0060] The moving mechanism 6 enables the four hoisting and unloading drums 604 to rise and fall synchronously, improving the stability during the transfer of ton packages;
[0061] By using the auxiliary guide mechanism 7, the hoisting steel rope 606 is kept in a vertical position between the guide pulley block 704 and the hoisting fixing plate 901, thereby reducing the impact of the change in the output position of the hoisting steel rope 606 on the stability of the hoisting fixing plate 901 when the hoisting unwinding drum 604 is lowered and retracted.
[0062] With the cooperation of the moving mechanism 6, the auxiliary guiding mechanism 7 and the hoisting mechanism 9, the auxiliary guiding mechanism 7 moves up and down, changing the vertical distance between the moving mechanism 6, the auxiliary guiding mechanism 7 and the hoisting mechanism 9, reducing the swaying caused by the inertia of the ton bag 10, and improving the safety and stability of the ton bag during transportation.
[0063] By cooperating with the telescopic connecting mechanism 8 and the hoisting mechanism 9, the connecting locking pin 807 is inserted into the through hole of the locking slot plate 902 through the inside of the hanging ring on the ton bag 10, so as to realize the stable connection between the hoisting mechanism 9 and the ton bag 10, which facilitates disassembly, hoisting and transportation.
