[0093] One end of the wire rope is connected to the swing mechanism tensioning cylinder 201, passes around the fixed pulley block connected to the end of the damping cylinder, and the other end is connected to the traction hinge 206 at the bottom of the reclaiming device 100. The extension and contraction of the tensioning cylinder drives the wire rope to move, thereby pulling the reclaiming device 100 to swing.

[0094] Preferably, the swing mechanism tensioning cylinder 201 is adapted to actively adjust the angle of the retrieving device 100 as required. Preferably, when the retrieving device 100 is acted upon by an external force, the swing mechanism tensioning cylinder 201 does not extend or contract.

[0095] Preferably, the swing reclaiming assembly of this embodiment is preferably applied to a ship unloader, the ship unloader extends out of the main beam 12, and the reclaiming device 100 is installed on the main beam 12. Specifically, the reclaiming device 100 is hingedly connected to the main beam 12 via a rotary shaft 103, so that the reclaiming device 100 can swing around the rotary shaft 103 relative to the main beam 12. Figure 12 As shown, the upper portion of the reclaiming device 100 is hingedly connected to the rotating shaft 103, allowing the reclaiming device 100 to swing about the rotating shaft 103. A traction hinge 206 is provided in the middle or lower middle portion of the reclaiming device 100. A swing mechanism 200 is flexibly connected to the traction hinge 206, specifically via a swing mechanism traction rope 202. This allows the reclaiming device 100 to maintain a first preset position when not subject to external forces. In the first preset position, a perpendicular line passing through the center of gravity of the reclaiming device 100 is spaced from the axis of the rotating shaft 103, and the torque of the reclaiming device under the action of gravity causes the reclaiming device to tend to move landward. Under the action of its own gravity, the reclaiming device tends to move landward around the rotating shaft 103.

[0096] It should be noted that the vertical line passing through the center of gravity of the material picking device is spaced apart from the axis of the rotating shaft 103, which means that the vertical line passing through the center of gravity of the material picking device does not pass through the axis of the rotating shaft 103, that is, the axis of the rotating shaft 103 and the center of gravity of the material picking device are not on the same straight line in the vertical direction.

[0097] The swing mechanism 200 provides traction to the reclaiming device 100 so that the reclaiming device 100 maintains a first preset position when not subject to external forces. In this position, there is always a torque toward the land side, which is balanced by the pulling force of the swing mechanism 200. When the reclaiming device 100 moves from the sea side to the land side, the gravity of the reclaiming device 100, which weighs tens of tons, can always push the reclaiming device 100 toward the front end of the movement direction, making it easier for the hopper to dig the material from the front. Even if the material is encountered, it can be overcome. When the reclaiming device 100 moves from the land side to the sea side, the tension of the traction wire rope always keeps the posture of the reclaiming device 100 stable.

[0098] When the cabin suddenly encounters a surge, in the direction of the ship width, if the force exerted by the surge on the ship and the material-reclaiming device 100 is toward the sea side, the material-reclaiming device 100 will tend to swing clockwise. At this time, the force of the surge applied to the material-reclaiming device 100 will only reduce the tension of the wire rope. If the torque of the surge force on the rotating shaft 103 exceeds the torque of the gravity on the rotating shaft 103, the material-reclaiming device 100 will swing slightly clockwise, converting the surge force into a swing, and avoiding transmitting the force to the ship unloader structure. If the surge forces the ship and reclaiming device 100 toward the landward side, the reclaiming device 100, subject to the resistance of the reclaiming, gravity, and the tension of the wire rope, is suddenly subjected to the surge force, causing the tension of the wire rope to increase rapidly. At this time, the force on the pulley at the end of the damping cylinder also increases rapidly. When the threshold is exceeded, the damping cylinder releases, the wire rope length increases, and the reclaiming device 100 swings counterclockwise to reach a new equilibrium state. The force applied to the reclaiming device 100 by the surge is converted into swaying of the reclaiming device 100, and does not affect the chain bucket ship unloader structure, ensuring the safety of the structure under surge.

[0099] The swinging material-grabbing assembly provided in this embodiment pulls the material-grabbing device 100 by the swinging mechanism 200, so that the material-grabbing device 100 is maintained in the first preset position when not subject to external force; and in the first preset position, the vertical line passing through the center of gravity of the material-grabbing device 100 is spaced apart from the axis of the rotating shaft 103, and the torque of the material-grabbing device under the action of gravity makes the material-grabbing device have a tendency to move toward the land side; thereby, the material-grabbing device can use the torque generated by its own gravity to assist in material-grabbing, while avoiding the impact of the material moving with the ship under the action of surge on the material-grabbing arm, avoiding the impact force from being transmitted to the structure of the ship unloader, and ensuring the safety and reliability of the structure.

[0100] Specifically, the swing mechanism 200 further includes a swing mechanism redirecting pulley 203 , which is disposed between the swing mechanism tensioning cylinder 201 and the traction hinge 206 and is in sliding contact with the swing mechanism traction rope 202 .

[0101] Specifically, the swing mechanism 200 also includes: a swing mechanism damping cylinder 204; a damping pulley 205, which is connected to the free end of the swing mechanism damping cylinder 204 and is in sliding contact with the swing mechanism traction rope 202; the damping pulley 205 is arranged between the swing mechanism redirecting pulley 203 and the traction hinge 206; the swing mechanism damping cylinder 204 is suitable for extending when the material picking device 100 is subjected to a torque toward the land side greater than a preset threshold, and contracting when the material picking device 100 is subjected to a torque toward the sea side.

[0102] Preferably, the rocking mechanism damping cylinder 204 can extend according to the external force applied to the reclaiming device 100, thereby adjusting the angle of the reclaiming device 100. If the reclaiming device 100 is subjected to a landward torque, the reclaiming device 100 pulls the rocking mechanism traction rope 202. If the force of the rocking mechanism traction rope 202 exceeds a preset threshold of the rocking mechanism damping cylinder 204, the rocking mechanism damping cylinder 204 extends. If the reclaiming device 100 is subjected to a seaward torque, the reclaiming device 100 reduces the force applied to the rocking mechanism traction rope 202, thereby causing the damping cylinder 204 to retract.

[0103] When a surge occurs, the rocking mechanism damping oil cylinder 204 extends or contracts according to the direction of the force. When the surge ends, the force on the rocking mechanism traction rope 202 returns to the state before the surge, and the extension of the rocking mechanism damping oil cylinder 204 will return to the state before the surge. At the same time, the angle of the reclaiming device 100 will also return to the state before the surge. The rocking reclaiming assembly provided in this embodiment is provided with a rocking mechanism damping oil cylinder 204, which extends when the reclaiming device 100 is subjected to a torque toward the land side, and contracts when the reclaiming device 100 is subjected to a torque toward the sea side. Thus, the length of the rocking mechanism traction rope 202 can be automatically adjusted according to the force applied to the reclaiming device 100, so that the reclaiming device 100 can quickly reach a new equilibrium state after being subjected to force, thereby ensuring that the force applied to the reclaiming device 100 during the surge is converted into a rocking motion of the reclaiming device 100, and does not act on the structure of the chain bucket ship unloader, thereby ensuring the safety of the structure under surge.

[0104] Specifically, the rocking mechanism tensioning cylinder 201 is adapted to extend and retract in the horizontal direction.

[0105] Specifically, the rocking mechanism damping cylinder 204 is adapted to extend and retract in the horizontal direction.

[0106] Optionally, the stroke of the tensioning cylinder of the rocking mechanism is greater than the stroke of the damping cylinder of the rocking mechanism.

[0107] Preferably, the force threshold of the swing mechanism tensioning cylinder 201 is greater than the force threshold of the swing mechanism damping cylinder 204, so that the swing mechanism tensioning cylinder 201 reacts more slowly when subjected to force than the swing mechanism damping cylinder 204. The swing mechanism tensioning cylinder 201 has a large stroke and a slow reaction, while the swing mechanism damping cylinder 204 has a small stroke and a fast reaction.

[0108] Specifically, the contraction of the swing mechanism tensioning cylinder 201 is suitable for increasing the angle between the axis of the material taking device 100 along its length and the vertical direction; the extension of the swing mechanism tensioning cylinder 201 is suitable for reducing the angle between the axis of the material taking device 100 along its length and the vertical direction.

[0109] Since a coaming is provided at the hatch of the cabin, the material below the coaming is difficult to be removed when the retrieving device 100 is in the normal operating position. Therefore, the swing retrieving assembly provided in this embodiment can also drive the retrieving device 100 to adjust the angle as needed.

[0110] Combine Figure 13 As shown, under normal operating conditions, the reclaiming device 100 is in a first swinging state 210. When the reclaiming device needs to be adjusted from the first swinging state 210 to the second swinging state 220, the swing mechanism tensioning cylinder 201 extends, and the reclaiming device 100 can be adjusted to the second swinging state 220 under the action of gravity torque. When it needs to be adjusted from the first swinging state 210 to the third swinging state 230, the swing mechanism tensioning cylinder 201 retracts, and the wire rope pulls the reclaiming device 100 to the third swinging state 230. By adjusting to different postures, it is easier to empty the ship's hold of leftover materials and reduce the amount of cargo clearance.

[0111] like Figure 1 As shown, although the L-shaped chain bucket ship unloader in the prior art solves environmental problems such as material leakage, the L-shaped chain bucket material head adopts a horizontal rotation feeding method, which easily causes the lower end of the chain bucket vertical arm to bear a large horizontal force, and is prone to excessive twisting of the material taking arm, thereby causing failure of the material taking arm rotation mechanism and the arm support rotation mechanism. In the rotary stacking feeding method, the feeding width is determined by three parameters: the chain bucket pitch, the chain speed, and the chain bucket movement speed. However, these parameters are also mutually restricted. Too fast speed will affect the feeding width, and too slow speed will affect the overall lifting efficiency. Therefore, the rotary material taking method limits the further improvement of efficiency. In order to solve the problem that the ship unloader is subjected to unreasonable force and is easily damaged and has low unloading efficiency, the material taking device provided in this embodiment includes:

[0112] A chain bucket arm 104; a bucket chain 110, which is composed of multiple buckets 111 connected end to end in sequence, and the bucket chain 110 is arranged around the outer peripheral side of the chain bucket arm 104; a driving unit, suitable for driving the bucket chain 110 to operate relative to the chain bucket arm 104; a rotating shaft 103, which is hingedly connected to the chain bucket arm 104, and the chain bucket arm 104 is suitable for swinging around the rotating shaft 103; the force direction of the bucket chain 110 when digging materials 30 is parallel to the rotating plane of the chain bucket arm 104.

[0113] Preferably, combined Figure 9 As shown, the force direction of the hopper chain 110 when digging the material 30 is the extension direction of the material taking section 150.

[0114] The hopper chain 110 is composed of a plurality of hoppers 111 connected end to end. The hopper chain 110 is constructed in a ring shape and is adapted to be driven by a drive unit to operate relative to the chain bucket arm 104. During the reciprocating motion, the hoppers 111 are used to scoop material. After the material is lifted to a certain height, the material 30 is dumped, and then the material is scooped again, and the process repeats.

[0115] Preferably, the force direction of the bucket chain 110 when digging materials 30 is parallel to the rotation plane of the chain bucket arm 104, so that the chain bucket arm 104 itself will not be subjected to additional force when the material-removing device is working. When the torsional force of the bucket chain 110 when digging materials 30 is too large, the chain bucket arm 104 will swing freely around the rotation axis 103 under the action of the force. The main loads on the material-removing device are within the plane where the material-removing device is located, avoiding the chain bucket arm 104 from being subjected to excessive force and malfunctioning, which is beneficial to extending the life of the equipment and improving efficiency.

[0116] The material-retrieving device provided in this embodiment is provided with a rotating shaft 103, so that the chain bucket arm 104 is suitable for swinging around the rotating shaft 103; and the force direction of the bucket chain 110 when digging materials 30 is parallel to the rotating plane of the chain bucket arm 104, thereby ensuring that the main load on the material-retrieving device is within the plane where the material-retrieving device is located, the force is more reasonable, the operation reliability is improved, and the chain bucket arm 104 is avoided from being malfunctioning due to excessive force, which is beneficial to extending the equipment life and improving efficiency.

[0117] Furthermore, the opening direction of the hopper 111 is parallel to the rotation plane of the hopper chain 110, and the opening direction of the hopper 111 is parallel to the rotation plane of the chain bucket arm 104. Furthermore, the opening direction of the hopper 111 is parallel to the translation direction of the material reclaiming device along the main beam 12, that is, a front feeding method is adopted, so that the hopper 111 can shovel the material into the hopper more directly when digging the material, greatly improving the working efficiency. The front feeding method can also prevent the material from being piled up at the head of the material reclaiming head, avoiding large lateral excavation resistance.

[0118] Specifically, the rotary shaft 103 is hinged to the upper portion of the chain bucket arm 104;

[0119] A vertical line passing through the center of gravity of the material taking device is spaced apart from the axis of the rotary shaft 103 .

[0120] It should be noted that the vertical line passing through the center of gravity of the reclaiming device is spaced apart from the axis of the rotating shaft 103. This means that the vertical line passing through the center of gravity of the reclaiming device does not pass through the axis of the rotating shaft 103, that is, the axis of the rotating shaft 103 and the center of gravity of the reclaiming device are not vertically aligned. To maintain this state, this embodiment provides a rocking mechanism 200 flexibly connected to the traction hinge 206 of the reclaiming device 100. The rocking mechanism 200 is adapted to pull the reclaiming device 100 so that the reclaiming device 100 maintains a first preset position when not subject to external forces. In the first preset position, the vertical line passing through the center of gravity of the reclaiming device 100 is spaced apart from the axis of the rotating shaft 103, and the torque of the reclaiming device under the action of gravity causes the reclaiming device to tend to move toward the landward direction.

[0121] The material picking device provided in this embodiment is arranged so that the vertical line passing through the center of gravity of the material picking device is spaced apart from the axis of the rotating shaft 103, so that the material picking device always has a tendency and torque to move toward the front end of the material picking, thereby increasing the pressure of the material picking device on the material. The material picking device can use the torque generated by its own gravity to always maintain a movement trend toward the head of the hopper, which facilitates material picking and reduces energy consumption.

[0122] Combine Figure 2 、 Figure 9 As shown, the material-retrieving device is roughly constructed in a herringbone shape. In the initial position, the center of gravity and the hinge point of the material-retrieving device are not in a straight line, and there is a torque. During excavation operations, the material-retrieving device can use the torque generated by its own gravity to always maintain a movement trend toward the head of the hopper. If it encounters resistance, such as compacted materials, the hopper can rely on its own gravity to always press the head against the compacted materials, thereby increasing the force to break the compacted materials and waiting for the hopper to excavate the materials in front before continuing to move forward, thereby improving the material-retrieving efficiency and reducing additional force. The material-retrieving device can even use its own gravity to complete the material-retrieving without the need for additional force, thereby reducing energy consumption.

[0123] Specifically, the driving unit includes: a driving motor 101; a driving sprocket 102, wherein the outer peripheral side of the driving sprocket 102 is in contact with the hopper chain 110, and the driving motor 101 is adapted to drive the hopper chain 110 to operate via the driving sprocket 102.

[0124] Preferably, the output shaft at the end of the driving motor 101 is connected to the driving sprocket 102 after being decelerated, and the driving sprocket 102 is located at the upper part of the material taking device.

[0125] Specifically, the rotation axis of the driving sprocket 102 coincides with the axis of the rotating shaft 103 .

[0126] Specifically, the retrieving device further includes: two tensioning sprockets 108 , which are arranged along the length direction of the chain bucket arm 104 at one end away from the driving sprocket 102 ;

[0127] The two tensioning sprockets 108 are suitable for stretching the hopper chain 110 and forming at least a portion of the hopper chain 110 into a material taking section 150 suitable for contacting the material 30 .

[0128] Combine Figure 9 As shown, the two tensioning sprockets 108 are located at the lower part of the material taking device. The two tensioning sprockets 108 can stretch the lower part of the hopper chain 110 so that multiple hoppers can be in an open forward state when running here, thereby facilitating multiple hoppers to take materials at the same time and improving the material taking efficiency.

[0129] Specifically, the retrieving device further includes a tensioning push rod 106 disposed between the two tensioning sprockets 108, adapted to maintain the two tensioning sprockets 108 relatively away from each other to tension the hopper chain 110. This ensures the tension of the hopper chain 110 and maintains the length of the retrieving section 150.

[0130] Specifically, a lifting section 120 suitable for lifting the material 30 is formed between the end of the material taking section 150 and the driving sprocket 102 .

[0131] It should be noted that the end of the reclaiming section 150 refers to the end of the hopper chain 110 in the rotation direction of the hopper chain 110, where the hopper chain 110 maintains contact with the material 30. Correspondingly, the head end of the reclaiming section 150 refers to the head end of the hopper chain 110 in the rotation direction of the hopper chain 110, where the hopper chain 110 maintains contact with the material 30.

[0132] Preferably, the material lifting section 120 in this embodiment is a straight line section. By setting the material lifting section 120 as a straight line section, the hopper is always kept in a straight line, ensuring a stable material lifting process.

[0133] Specifically, after the hopper chain 110 passes around the drive sprocket 102 from the end of the lifting section 120, the direction of the opening of the hopper 111 is changed and the unloading is completed; a first redirecting sprocket 1051 is provided between the driving sprocket 102 and the head end of the material taking section 150; the hopper chain 110 forms a first descending section 130 between the driving sprocket 102 and the first redirecting sprocket 1051, and forms a second descending section 140 between the first redirecting sprocket 1051 and the head end of the material taking section 150; the second descending section 140 is arranged at an angle to the first descending section 130.

[0134] Preferably, by arranging a first redirecting sprocket 1051 between the driving sprocket 102 and the head end of the material-taking section 150, the hopper chain 110 forms a first descending section 130 and a second descending section 140, and the second descending section 140 is set at an angle to the first descending section 130, so that the overall structure of the hopper chain 110 is roughly herringbone-shaped, that is, at the upper part of the material-taking device, the distance between the loaded hopper and the empty hopper is closer, so that the upper structure of the material-taking device is smaller, and at the lower part of the material-taking device, after being redirected by the first redirecting sprocket 1051, the lifting hopper and the descending hopper will move away from each other, and the descending hopper will bend at an angle, so that the lower part of the material-taking device forms a triangle-like shape, which is convenient for setting the material-taking section 150.

[0135] Preferably, by adopting a herringbone-shaped material-retrieving device, a method of feeding from the front of the hopper mouth edge line with a higher force efficiency ratio is adopted. At the bottom of the herringbone structure, in order to allow the material-retrieving arm to dig out materials under the hatch coaming, a material-retrieving section 150 of sufficient length is provided at the bottom of the material-retrieving device, so that the hopper can dig materials at high speed in the ship width direction, and the efficiency is greatly improved.

[0136] Traditional L-shaped reclaiming heads sweep left and right to allow material to enter the hopper. However, deep, narrow reclaiming devices make it difficult to unload cleanly. Furthermore, this rotary feeding method requires the use of an L-shaped reclaiming device in conjunction with a deep, narrow hopper to achieve rotary, stacking, and feeding. The reclaiming device provided in this embodiment utilizes a front reclaiming head with a herringbone structure. Compared to traditional chain bucket ship unloaders, this has a simpler structure, more evenly distributes force across the entire reclaiming device's bottom, and is less expensive.

[0137] Specifically, a second redirecting sprocket 1052 is provided between the driving sprocket 102 and the first redirecting sprocket 1051 , and the hopper chain 110 forms a discharge section 160 between the driving sprocket 102 and the second redirecting sprocket 1052 .

[0138] Preferably, a collecting device such as a funnel can be provided at a relatively lower position of the unloading section 160 to facilitate the subsequent transfer of materials. By providing the unloading section 160, the interference of the empty hopper moving downward with the full hopper that needs to be unloaded can be reduced, thereby ensuring the efficient unloading action.

[0139] Preferably, a dustproof cover 107 is provided outside the hopper chain 110. The hopper is only exposed at the lower part of the material taking device.

[0140] Due to the rotary feeding method used by conventional chain bucket ship unloaders, the chain bucket needs to be deep and narrow to facilitate digging, and deep and narrow chain buckets are not easy to unload cleanly. However, due to the front feeding method, the hopper of this embodiment can be set to a wide and shallow hopper, which is convenient for material entry and discharge.

[0141] Combine Figure 14 、 Figure 15 As shown, the hopper chain 110 is composed of hoppers 111 and connecting plates 112 connected alternately. Ear plates 114 are provided at both ends of the hopper 111. The ear plates 114 are provided with shaft holes. The connecting plates 112 are also provided with shaft holes. The ear plates 114 and the connecting plates 112 are hinged by pins, so that all the hoppers are connected together to form a hopper chain.

[0142] The reclaiming mechanism of a traditional bucket chain ship unloader utilizes a chain drive. The reclaiming bucket is mounted between two chains, and a drive mechanism drives the chains, which in turn drives the bucket. This drive method places high demands on the chain's performance. Furthermore, the chain is easily damaged, requiring regular replacement and resulting in high maintenance costs.

[0143] Preferably, in the reclaiming device provided in this embodiment, the hopper back plate 113 of the hopper 111 can directly participate in the transmission, eliminating the traditional chain transmission. Instead, the transmission is driven by a connecting plate and the hopper back plate. The connecting plate connects the hoppers, making the hoppers part of the transmission. The hopper not only serves as the working mechanism for scooping materials, but also participates in the transmission as part of the hopper chain, increasing the force-bearing area and improving reliability.

[0144] Preferably, the driving sprocket and the redirecting sprocket act on a connecting plate, which is connected to a pin on the back plate and is outside the hopper so that it does not interfere with the hopper during driving and redirecting. The connecting plate is made of high-strength material to ensure reliability during driving and redirecting.

[0145] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
