Description

Technical Field

[0001] The invention relates to the technical field of material grabbing, and in particular to a grab bucket of a dock ship unloader special for wood chips. Background Art

[0002] The wharf ship unloader is a key equipment in port loading and unloading operations. It is mainly used to unload bulk cargo such as bulk cargo, ore, grain, and wood from ships to the wharf or convey them to subsequent processing equipment. With the development of global trade, the cargo throughput of ports has increased year by year, which has put forward higher requirements on the efficiency, stability and adaptability of wharf ship unloaders. Traditional wharf ship unloaders are usually composed of grab buckets, conveyor belts, rotating mechanisms, cranes and other components. They rely on grab buckets to grab cargo from the ship's cabin and unload it to the wharf or conveyor belt.

[0003] Traditional ship unloader grabs are usually used to handle bulk cargo, ore, grain and other materials. Wood chips are small in size and irregular in shape. When the grab is closed, due to the different hardness, size and arrangement of wood chips, some wood chips may get stuck on the edge or corner of the grab, making it impossible to close the grab completely, leaving gaps. These gaps become channels for wood chips to leak, causing some wood chips to slip from the grab during the grab process, reducing the effective loading capacity and operating efficiency of the grab. In addition, this leakage may also cause wood chips to scatter in the operating area, increasing the workload of cleaning and maintenance. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a grab bucket for a dock ship unloader dedicated for wood chips, aiming to alleviate the above problems at least to a certain extent.

[0027] 3. Increase operation safety and stability:

[0028] The coordinated operation of the hydraulic parts and the rotating parts ensures that the snap-on frame can be stably closed after the grabbing task is completed, and the anti-pinch opening is kept closed during transportation. Even during long-distance transportation, the wood chips will not slip out of the bucket, further improving the safety of the operation. In addition, when unloading wood chips, the rotating parts can slightly shake the snap-on frame to remove the residual wood chips attached to the snap-on frame and prevent these residues from affecting the subsequent work of the bucket.

[0029] The present invention significantly improves the effect of wood chip processing by improving the structure and function of the bucket. While ensuring the capacity of the bucket, it effectively prevents wood chips from breaking and sliding, enhances operation stability and safety, and improves loading efficiency. Overall, the present invention provides an efficient and reliable solution, improves the performance of the ship unloader bucket, and has significant practical application value.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] refer to Figure 1-Figure 10 , a grab bucket for a dock unloader for wood chips, comprising:

[0047] Lifting plate 100;

[0048] A bracket 101 provided at the bottom of the hanging plate 100;

[0049] Two bucket bodies 102 are arranged on the bracket 101. The bucket bodies 102 can rotate with the bracket 101 as the center of a circle, and an anti-pinch opening 103 is formed between the two bucket bodies 102;

[0050] A grabbing frame 104 is disposed on the bucket body 102, and the grabbing frame 104 can slide on the bucket body 102;

[0051] A hydraulic component 105 is provided between the hoisting plate 100 and the grab frame 104, and a telescopic end of the hydraulic component 105 is connected to the grab frame 104;

[0052] Two buckle frames 106 are arranged on the bracket 101. The buckle frames 106 can rotate with the bracket 101 as the center. When the two buckle frames 106 rotate to a preset angle and are spliced, they can cover the anti-pinch opening 103;

[0053] A rotating component disposed between the grabbing frame 104 and the buckling frame 106, used to rotate the buckling frame 106, and the rotating component can rotate the buckling frame 106 when the grabbing frame 104 moves to a preset position;

[0054] Wherein, the rotating component can shake the buckle frame 106 when rotating the buckle frame 106 to a preset angle;

[0055] By setting the lifting plate 100, when in use, the operator can connect the lifting plate 100 to the traction cable of the ship unloader. When grabbing wood chips, the traction cable can be retracted and moved to make the lifting plate 100 correspond to the grabbing area of ​​the wood chip pile. The hydraulic component 105 can be used to move the position of the grabbing frame 104, so that the two buckle frames 106 located on the outer walls of the two bucket bodies 102 rotate with the bracket 101 as the center of the circle, leaving the bucket body 102, and the two bucket bodies 102 rotate with the bracket 101 as the center of the circle, and the bottoms of the two bucket bodies 102 gradually separate, and the anti-pinch opening 103 gradually increases, so as to facilitate grabbing. When grabbing wood chips, the hydraulic parts 105 can be used to push the two bucket bodies 102 to rotate to grab the wood chips. When the bucket bodies 102 rotate to a preset angle, the anti-pinch opening 103 formed between the two bucket bodies 102 will not subject the wood chips to excessive pressure, so that the wood chips will not be broken. This design ensures that when clamping wood chips, the bucket bodies 102 can maintain a proper distance between them to prevent excessive pressure on the wood chips due to excessive proximity of the bucket bodies 102, thereby effectively avoiding damage to the wood chips during the grabbing process, and the anti-pinch opening 103 is formed between the two bucket bodies 102. 3 will be temporarily fixed due to the friction between the multiple wood chips, which can effectively prevent the wood chips from slipping during the grabbing process. After the two bucket bodies 102 rotate to the initial angle, the hydraulic component 105 continues to work. When the two bucket bodies 102 rotate to the limit angle, the grabbing frame 104 can slide on the bucket bodies 102. At this time, the rotating component set can rotate the two buckle frames 106. The two buckle frames 106 rotate to close and cover the anti-pinch opening 103, and the wood chips can be safely wrapped therein. During transportation or handling, the closing of the two buckle frames 106 prevents The wood chips slide down from the anti-pinch opening 103. When the grabbing task is completed, the operator can operate the hydraulic component 105 again to make the grabbing frame 104 slide back to its original position, and the snap-fit ​​frame 106 also rotates to the initial angle to expose the anti-pinch opening 103. When the rotating component rotates the snap-fit ​​frame 106 to a preset angle, the snap-fit ​​frame 106 can be shaken to allow the wood chips that fall into the snap-fit ​​frame 106 after the grabbing work is completed and during the transportation of the wood chips to be separated from the snap-fit ​​frame 106. By slightly shaking, the wood chips attached to the snap-fit ​​frame 106 can be ensured to fall off smoothly, thereby avoiding the influence of subsequent operations due to the residual wood chips.

[0056] As a further solution of the present invention, a slide rail 200 is connected to the top of the bucket body 102, the grab frame 104 is slidably connected to the slide rail 200, one end of the hydraulic component 105 is rotatably connected to the bottom of the hanging plate 100, and the telescopic end of the hydraulic component 105 is rotatably connected to the grab frame 104;

[0057] By setting the hydraulic component 105, when in use, the hydraulic component 105 can be turned on, and the telescopic end of the hydraulic component 105 can be retracted and extended to allow the bucket body 102 to rotate. This design not only improves the flexibility and accuracy of operation, but also allows the angle of the bucket body 102 to be quickly adjusted under different operating conditions to adapt to wood chips of different shapes and sizes. The setting of the hydraulic component 105 ensures the smoothness and stability of the rotation of the bucket body 102, avoiding damage to the wood chips or reduced grabbing efficiency caused by improper operation. In this way, the hydraulic component 105 effectively optimizes the function of the bucket body 102, making it more adaptable and efficient during the wood chip loading process.

[0058] As a further solution of the present invention, a limit block 201 is connected to one side of the bracket 101, the limit block 201 is located in the anti-pinch opening 103, a fixed shaft 202 is connected to the bracket 101, and the bucket body 102 is rotatably connected to the fixed shaft 202;

[0059] By setting the limit block 201, the limit block 201 can limit the angle of the two bucket bodies 102 when the two bucket bodies 102 are about to rotate and close, ensuring that the closing angle of the bucket bodies 102 will not be too large, thereby preventing the wood chips from being subjected to excessive pressure and causing them to break. The limit block 201 is located in the anti-clamping opening 103. When the bucket body 102 rotates close to the closed position, the limit block 201 will contact the bucket body 102 to limit its rotation angle. In this way, the limit block 201 effectively controls the closing range of the bucket body 102, ensuring that the wood chips can be appropriately protected during the clamping process. In addition, the setting of the fixed shaft 202 enables the bucket body 102 to rotate smoothly around its central axis, further enhancing the stability and operating accuracy of the bucket body 102. The support of the fixed shaft 202 not only improves the smoothness of the rotation of the bucket body 102, but also reduces the risk of wood chip damage caused by uneven rotation. On the whole, the matching design of the limit block 201 and the fixed shaft 202 optimizes the performance of the bucket body 102, ensuring the integrity of the wood chips and the efficiency of the grabbing process.

[0060] As a further solution of the present invention, the rotating component includes a rotating shaft 203 rotatably connected to the bracket 101, the snap-fit ​​frame 106 is connected to the rotating shaft 203, the rotating shaft 203 is connected to a gear 204, and the bracket 101 is slidably connected to a rack 205;

[0061] By providing the rotating shaft 203, the rotating shaft 203 is connected to the buckle frame 106, and the precise rotation control of the buckle frame 106 is achieved. The gear 204 on the rotating shaft 203 cooperates with the rack 205 slidably connected to the bracket 101, and the rotating shaft 203 can be smoothly rotated through the meshing of the gear 204 and the rack 205.

[0062] As a further solution of the present invention, when the rotating shaft 203 rotates, the gear 204 drives the snap-fit ​​frame 106 to rotate synchronously, so that the snap-fit ​​frame 106 can be closed or opened at a preset angle position, ensuring the effective covering or exposure of the anti-pinch opening 103. The sliding connection design of the rack 205 allows the rotating shaft 203 to move smoothly on the bracket 101, improving the accuracy and stability of the rotation operation. This design not only ensures the reliability of the snap-fit ​​frame 106 during operation, but also enhances the flexibility and operating efficiency of the bucket 102 when handling wood chips. This setting of the rotating part enables the snap-fit ​​frame 106 to accurately cover or release the anti-pinch opening 103 during the process of grabbing wood chips, effectively preventing wood chips from slipping from the opening, while optimizing the grabbing and transportation process of wood chips.

[0063] As a further solution of the present invention, the rotating component further includes a push plate 206 disposed at the bottom of the hanging plate 100, a connecting plate 207 is connected to the rack 205, a connecting rod 208 is connected between the push plate 206 and the connecting plate 207, and a spring telescopic rod 209 is connected between the hanging plate 100 and the push plate 206;

[0064] By setting the spring telescopic rod 209, the spring telescopic rod 209 can accurately limit the position of the push plate 206. In application, when the push plate 206 moves downward, the spring telescopic rod 209 will limit the movement range of the push plate 206. The downward displacement of the push plate 206 acts on the connecting plate 207 through the connecting rod 208, thereby applying pressure to the connecting plate 207. Specifically, the push plate 206 and the connecting plate 207 are connected by the connecting rod 208, so that the movement of the push plate 206 can directly affect the position of the connecting plate 207. The connecting plate 207 is connected with a rack 205, and the rack 205 cooperates with the gear 204 on the rotating shaft 203. Through the action of the connecting rod 208, the movement of the push plate 206 will cause the corresponding movement of the rack 205. This movement will be transmitted to the rotating shaft 203, thereby realizing the rotation control of the snap-fit ​​frame 106.

[0065] As a further solution of the present invention, the rotating component further includes a slider 300 connected to the bottom of the grabbing frame 104, the slider 300 is slidably connected to the slide rail 200, a traction rope 301 is connected to the bottom of the push plate 206, one end of the traction rope 301 passes through the slide rail 200 and is connected to the push plate 206, and a first spring 302 is connected between the slider 300 and the slide rail 200;

[0066] By setting the first spring 302, the first spring 302 can limit the position of the slider 300 and the grab frame 104. After the two bucket bodies 102 are separated to grab the wood chips, the telescopic shaft of the hydraulic component 105 is extended, and the thrust of the grab frame 104 can be used to rotate the bucket body 102, gradually shortening the spacing of the anti-pinch opening 103. In this process, the first spring 302 remains unstretched to ensure the stability and position accuracy of the slider 300 on the slide rail 200. When the two bucket bodies 102 rotate to contact the limit block 201, the hydraulic component 105 continues to work, and the grab frame 104 slides on the slide rail 200. The slider 300 transmits the thrust to the traction rope 301 through the sliding of the slide rail 200, and the traction rope 301 can effectively pull the push plate 206 downward. The downward movement of the push plate 206 further promotes the movement of the connecting plate 207, and the rotation angle of the rotating component is accurately controlled through the cooperation of the rack 205 and the gear 204. This arrangement ensures that the snap-fit ​​frame 106 can be closed at a preset angle, thereby accurately covering the anti-pinch opening 103 and effectively grabbing and transporting wood chips. The overall design optimizes the working performance and reliability of the bucket body 102 through the linkage of the spring, the traction rope 301 and the push plate 206, ensures stability and accuracy during the grabbing process, reduces errors during operation, and improves the grabbing efficiency of wood chips.

[0067] As a further solution of the present invention, the bracket 101 is connected to the limit shaft 303, the connecting plate 207 is slidably connected to the limit shaft 303, and a second spring 304 is connected between the connecting plate 207 and the bracket 101;

[0068] By setting the limiting shaft 303, the limiting shaft 303 can provide effective guidance and restriction for the connecting plate 207, ensuring that the connecting plate 207 maintains a stable movement path during the sliding process. The setting of the limiting shaft 303 allows the connecting plate 207 to slide only along a specific track, preventing it from deflecting or swinging unnecessarily during the movement.

[0069] As a further solution of the present invention, a connection port 400 is provided on one side of the connection plate 207, the rack 205 is slidably connected in the connection port 400, connection grooves 401 are provided on both sides of the rack 205, a push rod 402 is slidably connected in the connection groove 401, one end of the push rod 402 is semi-spherical, a plurality of top grooves 403 are provided on both sides of the inner wall of the connection port 400, the top grooves 403 are semi-spherical grooves, the push rod 402 is sleeved with the corresponding top grooves 403, and a third spring 404 is connected between the push rod 402 and the connection groove 401;

[0070] By setting the third spring 404, the third spring 404 can provide appropriate elastic force for the push rod 402, so that it can remain stable after the rack 205 moves to the limit position. In this design, one end of the push rod 402 is semi-spherical, matching the semi-spherical top groove 403 on the inner wall of the connection port 400. This structure ensures that the push rod 402 can be firmly inserted into the top groove 403. When the connecting plate 207 allows the rack 205 to move to the limit position and the buckle frame 106 rotates to the limit angle, the grab frame 104 has not moved to the limit distance on the slide rail 200, that is, the push plate 206 will move downward for a distance, and the connecting plate 207 will move for a distance. When the gear 204 rotates to the limit angle, the rotation of the gear 204 is restricted, the movement of the rack 205 is restricted, and when the connecting plate 207 continues to move, the top groove 403 overcomes the friction between the top rod 402 and the top rod 402, so that the top rod 402 can be separated from one of the top grooves 403 and the third spring 404 is compressed, so that the top rod 402 can be separated from one of the top grooves 403 and the third spring 404 is compressed. In this process, the connecting plate 207 continues to move, and the top rod 402 will align with the next top groove 403. The third spring 404 releases the stored potential energy, allowing the top rod 402 to smoothly enter the next top groove 403. During this process, the impact between the top rod 402 and the top groove 403 will produce a slight shake. This shaking effect helps to remove wood chips remaining on the bucket body 102. At the same time, when the two snap-fit ​​frames 106 contact each other to close the anti-pinch opening 103, this shaking effect is also used to effectively enhance the closing stability of the snap-fit ​​frames 106 and ensure the closure of the anti-pinch opening 103.

[0071] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
