Anti-blocking hopper of ship unloader

Abstract

The invention relates to an anti-blocking hopper of a ship unloader. The hopper mainly comprises a hopper body, a connecting base, an excitation source, a spherical vibrating plate, a hinged shaft, a hinged shaft base, a buffer sleeve and an anti-overflow baffle plate. At a slope section where the hopper is easy to block, the spherical vibrating plate is arranged in the hopper body and is flexibly connected with the hopper body; the anti-overflow baffle plate is arranged on the upper part of a seam between the spherical vibrating plate and the hopper body; the hinged shaft is arranged on the hopper body through the hinged shaft base, and the vibration absorption buffer sleeve is arranged between the hinged shaft and the hinged shaft base; and the connecting base is arranged on the spherical vibrating plate, and the excitation source is fixed on the connecting base. The hopper can reduce the impact effect of vibration on the hopper body, avoid the damage of the vibration to the structure of the hopper body, reduce the noise of the vibration, is benefit for environmental protection, has good anti-blocking effect and can reduce the labor strength of workers and improve the continuity of transportation.

Description

technical field [0001] The invention relates to an anti-blocking material hopper of a ship unloader, which is used to solve the frequent material blockage of the loading and unloading hopper of the ship unloader and the hoppers at various reloading points in the bulk cargo belt conveying assembly line operation, and belongs to the technical field of port lifting and transportation machinery. Background technique [0002] The general technological process of bulk cargo loading and unloading at ports and wharfs is: material loading point (ship or yard) - ship unloader hopper or feed box - vibrating feeder or branching bucket - belt conveyor - transfer hopper - Belt conveyor—discharge port (ship or yard); in this process, the ship unloader hopper and each transfer hopper are often affected by material type, particle size, viscosity, fluidity, humidity, hopper structure and bucket body inclination, etc. The problem is that material blocking occurs, which in turn affects the effi...

Problems solved by technology

[0002] The general technological process of bulk cargo loading and unloading at ports and wharfs is: material loading point (ship or yard) - ship unloader hopper or feed box - vibrating feeder or branching bucket - belt conveyor - transfer hopper - Belt conveyor—discharge port (ship or yard); in this process, the ship unloader hopper and each transfer hopper are often affected by material type, particle size, viscosity, fluidity, humidity, hopper structure and bucket body inclination, etc. The problem of material blocking occurs, which affects the efficiency of loading and unloading and conveying

[0003] Material blockages in the discharge hopper and transfer hopper of the ship unloader occur from time to time, seriously affecting the loading and unloading process of the assembly line; at present, the common methods to solve the blockage are: 1. Direct manual cleaning and dredging; 2. Increase the slope of the hopper body when designing the hopper ; 3. Install the silo wall vibrator directly on the hopper body plate

[0004] The disadvantages of solving the hopper blockage above are: 1. Manual cleaning increases the labor intensity and working time of the laborers; at the same time, the material dust causes damage to the laborer's body and is not conducive to environmental protection; 2. When the opening of the hopper is constant, Increasing the slope of the bucket often increases the height of the overall layout of the hopper; and when the bucket door is arranged on the side of the bucket, the material will generate a large vertical downforce due to the excessive slope of the bucket (especially the material with poor fluidity and small particle size) , but it is not conducive to the lateral flow of materials; 3. The vibration motor is directly installed on the bucket body. To force the bucket body to vibrate, it is necessary to use a relatively high-power motor. The high-frequency centrifugal rotation of the motor produces alternating compound vibrations of up and down and back and forth. Long-term action will cause cracking of the bucket body and damage to the connecting bolts between the motor and the base, and the noise is also very loud.
