Description

Technical Field

[0001] The invention relates to the technical field of bulk cargo loading and unloading at ports, and in particular to a screw ship unloader. Background Art

[0002] Continuous ship unloader is a new type of environmentally friendly continuous ship unloading equipment, which is environmentally friendly and efficient. It has been used more and more widely in bulk material terminals in recent years. It conveys the material to the vertical screw conveyor through the rotation of the material taking head, and then transfers the material to the horizontal screw conveyor through the continuous lifting of the vertical screw, and then flows through the central chute and feeding belt conveyor, and finally unloads to the terminal belt conveyor.

[0003] When unloading coal, since the coal has been piled up at sea for a long time, the humid air causes moisture to be mixed inside the coal. When the coal is transported through the vertical screw shaft, the coal with a high moisture content may adhere to the outer wall of the screw shaft and get stuck at the connection between the screw shaft and the inner wall of the shell, affecting the unloading of the coal.

A square hole is opened on one side of the outer wall of the vertical conveying shell, and the outer wall of one end of the threaded plate is slidably connected to the inner wall of the square hole.

[0010] Furthermore, a sealing plate is fixedly connected to the top of the threaded plate, and a sliding block is rotatably connected to the end of the rotating plate away from the threaded plate. A fixed rod block is slidably connected to the inner wall of the sliding block, and the bottom of the fixed rod block is fixedly connected to the top of the horizontal conveying shell.

[0014] The present invention has the following beneficial effects: (1) In the present invention, the vertical conveying shell is moved to the top of the coal, and the motor is started. The motor drives the rotating shaft to rotate, and the rotating shaft drives the spiral rod to rotate. During the rotation of the spiral rod, it is closely fitted with the inner wall of the vertical conveying shell, and the coal can be transported to the inner top of the vertical conveying shell. At this time, the coal enters the top of the conveyor belt through the connection between the vertical conveying shell and the horizontal conveying shell, and is transported by the conveyor belt so that the coal can be unloaded. At the same time, the rotating shaft drives the reciprocating screw to rotate. During the rotation of the reciprocating screw, it is limited by the limit shell, and the reciprocating screw can drive the spiral rod to rotate. The patterned plate is raised and lowered, the threaded plate drives the round sleeve to be raised and lowered, and the round sleeve drives the sealing ring to be raised and lowered. During the lifting process of the sealing ring, it can come into contact with the top of the vertical sleeve rod, so that the vertical sleeve rod moves toward the inner cavity of the spiral rod. At the same time, due to the elastic deformation of the spring, the vertical sleeve rod can be reset, so that the air pressure in the inner cavity of the spiral rod is reciprocated and squeezed. The internal air pressure is heated up in the process of reciprocating extrusion, and the increased temperature can be transmitted to the spiral rod. When the spiral rod transports coal, the coal can be dried to prevent the coal from being too damp after transportation, which affects the subsequent use of the coal.

[0015] (2) According to the present invention, when the threaded plate is lifted or lowered, the inner wall of the top end of the vertical conveying shell can be made into a roughly sealed area. When the circular sleeve drives the sealing ring to be lifted or lowered, the inner wall of the sealing ring is fitted with the outer wall of the rotating shaft, which can prevent the airflow at the top end of the vertical conveying shell from being discharged to the bottom end of the vertical conveying shell through the threaded groove of the reciprocating screw, thereby improving the sealing effect. When the threaded plate is moved upward, the airflow at the top end of the vertical conveying shell can enter the interior of the limiting shell through the air hole. At this time, the airflow is heated by the heating plate, so that the airflow is converted into hot air. The hot airflow passes through the limiting shell and enters the interior of the diffuser. The hot airflow is sprayed toward the connection between the vertical conveying shell and the horizontal conveying shell through the diffuser, thereby further improving the drying process of the coal by the device and preventing the wet coal particles from adhering to the connection between the vertical conveying shell and the horizontal conveying shell.

[0016] (3) In the present invention, when the threaded plate falls, the threaded plate drives the rotating plate to fall, and is limited by the fixed rod block. The rotating plate drives the slider to slide along the outer wall of the fixed rod block, and the slider drives the bent rod to move, and the bent rod drives the square plate to move. During the movement of the square plate, it can come into contact with the circular plate to squeeze the circular plate. The circular plate drives the pushing frame to move. During the movement of the pushing frame, the coal pile is pushed, so that the coal enters the connection between the vertical conveying shell and the horizontal conveying shell under the influence of the squeezing force, and then falls to the top of the conveyor belt, preventing the coal from being stuck at the connection between the vertical conveying shell and the horizontal conveying shell during transportation, thereby improving the coal transportation efficiency. When the threaded plate falls, the threaded plate drives the sealing plate to move downward. During the downward movement of the sealing plate, it will fit with the opening of the square hole, preventing the airflow at the top of the vertical conveying shell from being discharged outward through the square hole, thereby further improving the sealing effect at the top of the vertical conveying shell.

[0017] (4) In the present invention, when the square plate and the circular plate move away from each other, the square plate drives the rotating bar to move, which is limited by the limiting rod. The rotating bar drives the sliding plate to slide along the outer wall of the limiting rod. During the sliding process of the sliding plate, it will come into contact with the impact plate, causing the impact plate to be squeezed. The impact plate drives the impact rod to move. During the movement of the impact rod, it will come into contact with the outer wall of the vertical conveying shell, causing the coal particles adhered to the inner wall of the vertical conveying shell to vibrate and fall off, thereby preventing the coal particles from getting stuck in the rotation of the spiral rod, thereby improving the stability of the spiral rod in conveying coal.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

During the movement of the square plate 878, it can come into contact with the circular plate 879 to squeeze the circular plate 879. The circular plate 879 drives the pushing frame 8711 to move. During the movement of the pushing frame 8711, the coal pile will be pushed, so that the coal is affected by the squeezing force and enters the connection between the vertical conveying shell 82 and the horizontal conveying shell 4, and then falls to the top of the conveyor belt 81, preventing the coal from being stuck in the connection between the vertical conveying shell 82 and the horizontal conveying shell 4 during transportation.

[0030] An impact assembly 88 is provided on one side of the square plate 878, and the impact assembly 88 includes a rotating bar 881 rotatably connected to both ends of the square plate 878 close to the bending rod 877, and the end of the rotating bar 881 away from the square plate 878 is rotatably connected to a sliding plate 882, and the inner wall of the sliding plate 882 is slidably connected to a limiting rod 883, and one end of the limiting rod 883 is fixedly connected to one side of the vertical conveying shell 82.

At this time, the coal enters the top of the conveyor belt 81 through the connection between the vertical conveying shell 82 and the horizontal conveying shell 4, and is transported by the conveyor belt 81, so that the coal can complete the unloading work. At the same time, the rotating shaft 84 drives the reciprocating screw rod 851 to rotate.

When the spiral rod 857 is in the process of transporting coal, the coal can be dried to prevent the coal from being too damp after transportation and affecting the subsequent use of the coal.

[0033] When the threaded plate 852 is lifted or lowered, the inner wall of the top end of the vertical conveying shell 82 can be made into a roughly sealed area. During the lifting process of the sealing ring 854 driven by the circular sleeve 853, the inner wall of the sealing ring 854 is fitted with the outer wall of the rotating shaft 84, which can prevent the airflow at the top end of the vertical conveying shell 82 from being discharged to the bottom end of the vertical conveying shell 82 through the threaded groove of the reciprocating screw 851, thereby improving the sealing effect. When the threaded plate 852 is moved upward, the airflow at the top end of the vertical conveying shell 82 can enter the interior of the limiting shell 861 through the air hole 862. At this time, the airflow is heated by the heating plate 863, so that the airflow is converted into hot air. The hot airflow passes through the limiting shell 861 and enters the interior of the diffuser 864. The hot airflow passes through the diffuser 864 to spray toward the connection between the vertical conveying shell 82 and the horizontal conveying shell 4, thereby further improving the drying treatment of the coal by the device and preventing wet coal particles from adhering to the connection between the vertical conveying shell 82 and the horizontal conveying shell 4.

During the movement of the square plate 878, it can come into contact with the circular plate 879 to squeeze the circular plate 879. The circular plate 879 drives the pushing frame 8711 to move. During the movement of the pushing frame 8711, the coal pile will be pushed, so that the coal is squeezed. The force enters the connection between the vertical conveying shell 82 and the horizontal conveying shell 4, and then falls to the top of the conveyor belt 81, preventing the coal from being stuck in the connection between the vertical conveying shell 82 and the horizontal conveying shell 4 during transportation, thereby improving the coal transportation efficiency. When the threaded plate 852 falls, the threaded plate 852 drives the sealing plate 873 to move downward. During the downward movement of the sealing plate 873, it will fit with the opening of the square hole 872, preventing the airflow at the top of the vertical conveying shell 82 from being discharged outward through the square hole 872, thereby further improving the sealing effect of the top of the vertical conveying shell 82.

[0035] When the square plate 878 and the circular plate 879 move away from each other, the square plate 878 drives the rotating bar 881 to move, and is limited by the limiting rod 883. The rotating bar 881 drives the sliding plate 882 to slide along the outer wall of the limiting rod 883. During the sliding process of the sliding plate 882, it will contact the impact plate 884, so that the impact plate 884 is squeezed, and the impact plate 884 drives the impact rod 886 to move. During the movement of the impact rod 886, it will contact the outer wall of the vertical conveying shell 82, causing the coal particles adhered to the inner wall of the vertical conveying shell 82 to vibrate and fall off, preventing the coal particles from getting stuck in the rotation of the screw rod 857, thereby improving the stability of the screw rod 857 in conveying coal.
