Description

Technical Field

[0001] The invention relates to the technical field of chain ship unloading, and in particular to a chain ship unloading device. Background Art

[0002] The chain unloading device is a special machine that uses continuous conveying machinery to make a head that can lift bulk materials, or has the ability to take materials by itself, or is equipped with a taking and feeding device to continuously lift the bulk materials out of the cabin, and then unload them to the arm or frame and transport them to the main conveying system on the shore to improve the unloading efficiency.

[0003] For example, in the Chinese patent with the authorization announcement number CN110255226B, which is named a gantry-type chain bucket ship unloader, the barge enters the dock to carry out the ship unloading operation, and the support frame is located directly above the materials in the barge. The hoisting device releases the wire rope, and the wire rope pulls the support frame to rotate around the hinge point, so that the chain bucket can grab the material, and the chain bucket transmission device starts to drive the chain to rotate. After the chain bucket grabs the material, it rotates upward around the guide wheel and unloads it into the second unloading funnel, and then the second unloading funnel transports the material to the pulley inside the machine. The pulley inside the machine starts to transport the material to the first unloading funnel, and the first unloading funnel transports the material to the dock belt conveyor, and then the gantry is adjusted to travel on the two dock tracks and the steel structure travels on the two tracks.

[0004] With respect to the above-mentioned related technologies, during the continuous digging process of the chain bucket, as the material gradually decreases, the depth of the chain bucket entering the material gradually decreases, thereby reducing the efficiency of the chain bucket in transporting the material upward. When the chain bucket flips upward around the guide wheel after digging the material, some of the material will fall from the edge of the chain bucket away from the chain, thereby reducing the feeding efficiency of the chain bucket. Summary of the invention

The push plate continuously abuts against the edge of the chain bucket, reducing the amount of material spilled in the chain bucket. At the same time, the ratchet mechanism is used to rotate the push plate during the upward movement, so that the material between the push plate and the side wall of the second bracket flows between the push plate and the chain conveyor, thereby allowing the material to flow in the direction of the next chain bucket, so that the push plate can continue to push the material to move, thereby improving the feeding efficiency of the chain bucket.

DETAILED DESCRIPTION

[0030] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 7, the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0031] This embodiment provides a chain ship unloading device, referring to Figure 1 and Figure 2 A chain unloading device includes a load vehicle 1, a first bracket 2, a second bracket 3, a chain conveyor 31, a chain bucket 311, a telescopic rod 32, an extrusion spring 321, a support shell 34, a support rod 35, a rotating pin 36, a push plate 37, a first reset torsion spring 38, an unlocking rod 39, a locking spring 391 and a ratchet mechanism 4 for locking the push plate 37. The ratchet mechanism 4 limits the rotation of the push plate 37 so that the push plate 37 can cooperate with the chain bucket 311 to pile up the materials. The ratchet mechanism 4 disengages from the push plate 37 so that the external materials can enter between the chain bucket 311 and the push plate 37 again.

[0032] Reference Figure 1 and Figure 2 The first bracket 2 is hinged on the truck 1, and the second bracket 3 is hinged on the end of the first bracket 2 away from the truck 1. The first bracket 2 and the second bracket 3 can be controlled to rotate to different angles by a rotation source such as a motor, so as to move the chain bucket 311 to different positions. This is a prior art and will not be described in detail here. The chain conveyor 31 is arranged inside the second bracket 3, and the chain bucket 311 is fixed on the chain conveyor 31. A plurality of chain buckets 311 are arranged along the circumference of the chain conveyor 31. The chain buckets 311 run counterclockwise from bottom to top to transport materials upward.

[0033] Reference Figure 3 , Figure 4 and Figure 5The telescopic rod 32 is fixedly connected to the inner side of the second bracket 3, and the extrusion spring 321 is arranged inside the telescopic rod 32 to push the telescopic rod 32 to be in an extended state. A damper is arranged inside the telescopic rod 32 to enable the telescopic rod 32 to slowly extend. The support shell 34 is fixedly connected to the end of the telescopic rod 32 away from the inner side of the second bracket 3, and the support rod 35 is slidably connected in the support shell 34. The push plate 37 is hinged to the support rod 35 through a rotating pin 36, and the rotating pin 36 is fixedly connected to the push plate 37, and the rotating pin 36 is rotatably connected to the support rod 35. The rotating pin 36 is composed of a first pin shaft 361 and a second pin shaft 362, and the first pin shaft 361 and the second pin shaft 362 are arranged on both sides of the push plate 37. The first reset torsion spring 38 is fixedly connected between the support rod 35 and the push plate 37, and the first reset torsion spring 38 is sleeved on the outer side of the first pin shaft 361, and the first reset torsion spring 38 is used to drive the push plate 37 to rotate to a vertical state. The outer side surface of the push plate 37 is fixedly connected with a transmission part 371 that can abut against the top wall of the chain bucket 311.

[0034] Reference Figure 4 , Figure 5 and Figure 6 The unlocking rod 39 is slidably connected to the support rod 35, and the locking spring 391 is sleeved on the outer side of the unlocking rod 39 to push the unlocking rod 39 out of the ratchet mechanism 4. The ratchet mechanism 4 includes a connecting frame 41, a locking ratchet 42, a locking pawl 43 and a second reset torsion spring 45. The connecting frame 41 is fixedly connected to the side of the support rod 35, and the locking ratchet 42 and the locking pawl 43 are both rotatably connected to the connecting frame 41. The locking ratchet 42 is fixedly sleeved on the outer side of the second pin shaft 362, so that the locking ratchet 42 is fixedly connected to the push plate 37 through the second pin shaft 362. The locking pawl 43 cooperates with the locking ratchet 42 to limit the counterclockwise rotation of the locking ratchet 42 (refer to Figure 5 ), the locking pawl 43 is fixedly connected to a transmission rod 44, and the transmission rod 44 can be pushed and rotated by the unlocking rod 39 to disengage the locking pawl 43 from the locking ratchet 42, and the second reset torsion spring 45 is fixedly connected between the connecting frame 41 and the locking ratchet 42, and the second reset torsion spring 45 is used to drive the locking pawl 43 to engage with the locking ratchet 42.

[0035] The push plate 37 moves downward into the material below the second bracket 3, and the extrusion spring 321 pushes the telescopic rod 32 to extend. Since the locking pawl 43 restricts the locking ratchet 42 from rotating counterclockwise (refer to Figure 5), and the locking ratchet 42 is fixedly connected to the push plate 37, so the push plate 37 cannot rotate counterclockwise relative to the support rod 35, and the telescopic rod 32 pushes the push plate 37 to move close to the chain bucket 311 through the support shell 34 and the support rod 35. During the movement of the push plate 37, the material is pushed close to the chain bucket 311, and at the same time, the chain bucket 311 rotates close to the push plate 37. The push plate 37 and the chain bucket 311 approach each other to gather the materials into a pile for shoveling, until the upper surface of the chain bucket 311 contacts the bottom surface of the transmission part 371. The chain bucket 311 rotates upward and pushes the push plate 37 upward through the transmission part 371, so that the push plate 37 and the chain bucket 311 are continuously in contact, reducing the amount of material falling downward during the rotation of the push plate 37.

[0036] The chain bucket 311 rotates and pushes the push plate 37 upwards, and at the same time, the chain bucket 311 pushes the push plate 37 to move away from the chain conveyor 31 in the horizontal direction, so that the telescopic rod 32 and the extrusion spring 321 are compressed. Since the locking pawl 43 does not restrict the push plate 37 from rotating clockwise, the chain bucket 311 pushes the push plate 37 to rotate clockwise around the rotating pin 36 through the transmission part 371 during the rotation process, and the chain bucket 311 continues to rotate upward to disengage from the push plate 37. Because the locking pawl 43 cooperates with the locking ratchet 42 to lock the angle of the push plate 37 that has rotated clockwise, the bottom surface of the push plate 37 moves upward, and the push plate 37 is pushed upward by the chain bucket 311. At this time, the material between the push plate 37 and the side wall of the second bracket 3 flows between the push plate 37 and the chain conveyor 31, so that the material can flow in the direction of the next chain bucket 311.

[0037] In the process that the chain bucket 311 pushes the push plate 37 to move away from the chain conveyor 31 in the horizontal direction, the support rod 35, the locking ratchet 42, the locking pawl 43 and the unlocking rod 39 move synchronously with the support rod 35, the unlocking rod 39 moves to abut against the limit rod 33, the limit rod 33 pushes the unlocking rod 39 to move close to the transmission rod 44, and the unlocking rod 39 pushes the transmission rod 44 to rotate counterclockwise (refer to Figure 5 ), the locking pawl 43 rotates synchronously with the transmission rod 44 to disengage from the locking ratchet 42, so that the locking ratchet 42 is unlocked. At this time, the push plate 37 can rotate counterclockwise relative to the support rod 35, and the first reset torsion spring 38 pushes the push plate 37 to rotate to a vertical state. Since the unlocking rod 39 is T-shaped, the unlocking rod 39 can continue to abut against the limit rod 33 in the vertical direction. The bottom surface of the transmission part 371 is arc-shaped. During the unlocking process, the transmission part 371 rotates synchronously with the push plate 37, so that the transmission part 371 is separated from the chain bucket 311, and the chain bucket 311 continues to rotate upward. The support rod 35 and the push plate 37 fall and reset by their own gravity. At the same time, the unlocking rod 39 is separated from the limit rod 33, and the locking spring 391 pushes the unlocking rod 39 to disengage from the transmission rod 44. The locking pawl 43 rotates and resets to abut against the locking ratchet 42.

[0038] The push plate 37 drives the material to move closer to the chain bucket 311, increasing the amount of material scooped up by the chain bucket 311. At the same time, the upward flipping stroke of the chain bucket 311 drives the push plate 37 to move upward synchronously. The push plate 37 continuously abuts against the edge of the chain bucket 311, reducing the amount of material spilled from the chain bucket 311. At the same time, the ratchet mechanism 4 is used to rotate the push plate 37 during the upward movement, so that the material between the push plate 37 and the side wall of the second bracket 3 flows between the push plate 37 and the chain conveyor 31, thereby allowing the material to flow in the direction of the next chain bucket 311, so that the push plate 37 can continue to push the material to move, thereby improving the feeding efficiency of the chain bucket 311.

[0039] Reference Figure 2 The outer side of the push plate 37 is fixedly connected with a material resistance plate 363, which is arranged on both sides of the chain bucket 311 to prevent materials from falling from both sides of the chain bucket 311, thereby improving the feeding efficiency of the chain bucket 311.

[0040] Reference Figure 4 A guide rod 341 is fixedly connected to the inside of the support shell 34, and the support rod 35 is slidably connected to the guide rod 341. A first return spring 342 is sleeved on the outer side of the guide rod 341. The first return spring 342 can push the support rod 35 downward, and the push plate 37 moves downward synchronously with the support rod 35, thereby increasing the material eating depth of the push plate 37 and increasing the amount of material pushed by the push plate 37 to the chain bucket 311.

[0041] Reference Figure 1 A belt conveyor 21 is provided in the first bracket 2, and the belt conveyor 21 is used to receive the material in the chain bucket 311 and convey the material to the material storage area in the truck 1. The truck 1 adopts the excavation method, by driving the first bracket 2 and the second bracket 3 to rotate, and cooperates with the movement of the truck 1, so that the truck 1 can better adapt to different working scenes, so that the truck 1 and the chain bucket 311 can flexibly load materials.

[0042] Reference Figure 2 and Figure 7 The inner side of the second bracket 3 is fixedly connected with the first guide rail 5 and the second guide rail 51, which are arranged above the push plate 37, the middle part of the first guide rail 5 is gradually bent away from the first guide rail 5, and the middle part of the second guide rail 51 is bent close to the chain bucket 311, the first guide rail 5 is slidably connected with the sliding plate 52, and the second guide rail 51 is slidably connected with the material plate 53, the material plate 53 is slidably connected with the sliding plate 52, and the sliding plate 52 moves upward to drive the material plate 53 to move inside the chain bucket 311. The bottom wall of the sliding plate 52 is provided with a transmission groove 521, and the chain bucket 311 moves upward to abut against the inner top surface of the transmission groove 521.

[0043] After the chain bucket 311 disengages from the transmission part 371, it continues to move upward and enters the transmission groove 521. The chain bucket 311 moves upward and drives the sliding plate 52 to move upward through the inner top wall of the transmission groove 521. The material plate 53 moves upward synchronously with the sliding plate 52. The sliding plate 52 moves upward along the length direction of the first guide rail 5. The arc-shaped first guide rail 5 adapts to the upward flipping stroke of the chain bucket 311. The material plate 53 moves to the middle of the second guide rail 51, and the material plate 53 moves horizontally toward the inside of the chain bucket 311. During the movement of the material plate 53, the material on the edge of the chain bucket 311 is pushed toward the middle of the chain bucket 311.

[0044] Since the first bracket 2 and the second bracket 3 will adjust the corresponding rotation angles according to the different locations of the materials, the second bracket 3 will have material spilled during the rotation adjustment process. The material plate 53 pushes the material to the middle of the chain bucket 311, reducing the amount of material spilled in the chain bucket 311 during the rotation of the second bracket 3 and improving the feeding efficiency of the chain bucket 311.

[0045] The upper surface of the first guide rail 5 is fixedly connected to the third guide rail 54, and the third guide rail 54 is gradually arranged away from the chain bucket 311. The sliding plate 52 and the material plate 53 continue to move upward under the push of the chain bucket 311, the material plate 53 gradually moves out of the chain bucket 311, the sliding plate 52 moves into the third guide rail 54, and the sliding plate 52 moves away from the chain bucket 311 in the horizontal direction, so that the sliding plate 52 is separated from the chain bucket 311, the chain bucket 311 continues to transport materials upward, and the sliding plate 52 is reset by free fall.

[0046] Reference Figure 3 and Figure 7 The push plate 37 can move upward into the transmission groove 521, so that the chain bucket 311 can smoothly transition from the material resistance plate 363 to the sliding plate 52, and in the process of the chain bucket 311 moving close to the sliding plate 52, the material resistance plate 363 can always prevent the material in the chain bucket 311 from spilling out.

[0047] The implementation principle of a chain unloading device in an embodiment of the present invention is as follows: the push plate 37 moves downward into the material under the second bracket 3, the telescopic rod 32 pushes the push plate 37 to move close to the chain bucket 311, and the push plate 37 pushes the material to move close to the chain bucket 311 during the movement. The push plate 37 and the chain bucket 311 approach each other to gather the material into a pile for shoveling, and the chain bucket 311 rotates upward and pushes the push plate 37 upward through the transmission part 371.

[0048] At the same time, the chain bucket 311 pushes the push plate 37 to move away from the chain conveyor 31 in the horizontal direction, and the chain bucket 311 rotates to push the push plate 37 to rotate around the rotating pin 36. At this time, the bottom surface of the push plate 37 moves upward, and the material between the push plate 37 and the side wall of the second bracket 3 flows between the push plate 37 and the chain conveyor 31. The chain bucket 311 continues to rotate upward to disengage from the push plate 37, and the limit rod 33 pushes the unlocking rod 39 to unlock the ratchet mechanism 4, and the support rod 35 and the push plate 37 move downward to reset, and the push plate 37 reverses and resets at the same time.

[0049] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
