Ship unloaders discharging hopper and reprinting hopper putty phenomenon happen occasionally, and have a strong impact on conveyor line loading and unloading operation flow process; Usually the common method that solves putty at present has: 1, the direct labor clears up mediation; 2, when hopper design, increase the bucket body gradient; 3, directly on hopper bucket body plate, install hopper wall vibrator additional.

The shortcoming that more than solves the hopper putty is: 1, the labor cleaning has increased laborer's labour intensity and production time; The material dust has caused infringement to laborer's health simultaneously, also is unfavorable for environmental protection; 2,, increase the bucket body gradient and tend to make the entire arrangement height of hopper to increase in opening degree one timing of hopper; And when sluice gate is arranged in the bucket body side, produce very big vertical depression power (material that especially flowing power is poor, granularity is little) because the bucket body gradient is crossed ambassador's material, be unfavorable for the lateral flow of material on the contrary; 3, directly vibrating motor is installed on the bucket body, motor and bucket body genus are rigidly connected, this kind installation form is because the big natural frequency of vibration of ship unloaders hopper self rigidity is lower, will select more high-performance motor for use in order to force the bucket body vibration, the centrifugal rotation of the high frequency of motor produces up and down and the reciprocal alternation compound vibration in front and back, long duration of action can cause bucket body cracking and motor and base tie bolt to damage, and noise is also very big.

Summary of the invention

The objective of the invention is to overcome above-mentioned weak point, thereby a kind of anti-blocking hopper of ship unloader is provided, can reduce the impact effect of vibration bucket body; Avoided the damage of vibration to the bucket body structure; Reduce vibration noise, help environmental protection; Blocking-proof result is good, and can alleviate working strength of workers, improves the continuity of carrying operation.

According to technical scheme provided by the invention, a kind of anti-blocking hopper of ship unloader comprises hopper body, Connection Block, exciting source, sphere oscillating plate, hinge, hinged block, buffering spacer, anti-overflow baffle plate, arrange the sphere oscillating plate in the slope section hopper body of putty takes place hopper easily, described sphere oscillating plate and hopper body flexibly connect; Seam top at described sphere oscillating plate and hopper body is provided with the anti-overflow baffle plate; Hinge is installed on the hopper body by hinged block, and absorbing buffering spacer is installed between hinge and hinged block; On the described sphere oscillating plate Connection Block is installed, exciting source is fixed on the Connection Block.Described exciting source adopts high frequency miniwatt vibrating motor by a narrow margin.Described sphere oscillating plate adopts spherical structure, and the material mechanical characteristics should satisfy shock-resistant and resistance to abrasion.

Compared with the prior art the present invention has the following advantages:

1, oscillating plate and bucket body flexibly connect, the exciting eccentricity of exciting source all be converted into oscillating plate about, front and back reciprocal alternating motions, cushion spacer simultaneously and reduced the impact effect of vibration bucket body; Avoided the damage of vibration to the bucket body structure;

2, flexibly connect, make vibratory force directly act on oscillating plate, soruce of vibration power reduces relatively, and then reduces vibration noise, helps environmental protection;

Unfavorable operating modes such as 3, this is practical simple in structure, and cost of manufacture is low, and the conversion of its vibratory force transmits that the base reason is applicable to that various small grain size, flowing power are poor, high humidity and the operating environment temperature difference are big anti-blocking, practicality is wider relatively, also can be used for the transformation of existing hopper;

The specific embodiment

Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:

As shown in Figure 1: comprise exciting source 1, Connection Block 2, sphere oscillating plate 3, hinge 4, hinged block 5, buffering spacer 6, anti-overflow baffle plate 7, hopper body 8 etc.

The present invention adopts in the slope section hopper body 8 of putty takes place hopper easily and arranges sphere oscillating plate 3, and described sphere oscillating plate 3 and hopper body 8 usefulness hinges flexibly connect; For preventing that oscillating plate and bucket body seam from spilling material, be provided with anti-overflow baffle plate 7 on the seam top of described sphere oscillating plate 3 and hopper body 8; Hinge 4 is installed on the hopper body 8 by hinged block 5, at hinge 4 and 5 of hinged blocks absorbing buffering spacer 6 is installed; Connection Block 2 is installed on the described sphere oscillating plate 3, and exciting source 1 is fixed on the Connection Block 2.Described exciting source 1 adopts high frequency miniwatt vibrating motor by a narrow margin.By connecting base 2 vibration is reached sphere oscillating plate 3; Described sphere oscillating plate 3 surfaces are the spherical surface structure, and the material mechanical characteristics should satisfy shock-resistant and resistance to abrasion.

The principle of work of the anti-blocking hopper of the present invention:

When hopper stockpiles material, material will accumulate the hopper bottom, because the relative loose characteristic of material gravity with bulk goods material physical structure, material will produce lateral pressure (how much relevant this lateral pressure size is with material unit weight and accumulating amount) to hopper body and mounting spherical oscillating plate slope section, and then generation lateral sliding resistance, simultaneously when the speed of streams material bin during greater than discharging speed, will aggravate the mutual embeddeding action between material particles, increase the relative motion friction drag of storeroom, further increase material side to sliding resistance.The anti-blocking structure of the present invention is exactly to utilize the centrifugal of exciting source to rotatablely move, by Connection Block with centrifugal rotatablely move be converted into oscillating plate about, the reciprocal alternating motion in front and back; The up-and-down movement of sphere oscillating plate can make material and sphere oscillating plate faying face produce slide relative, this sliding failure the static pressure balance between material and bucket body side, oscillating plate also is the center swing with the hinge simultaneously, these front and back tropism swing can destroy the interlayer binding force of material particles, breaks the mutual embedding internal friction balance of material bed particle; And sphere oscillating plate surface is spherical surface, and the direction of the friction drag that sphere and storeroom produce is along the sphere tangential distribution, and this distribution is disorderly and unsystematic, also can destroy the directivity balance of friction force between material and oscillating plate; Add the pressure release effect of sluice gate mouth when opening, material will quicken to glide, and guarantees that the hopper discharging is smooth and easy.
