Description
Technical field
The present invention relates to technical field of engineering machinery more particularly to a kind of feed hopper and the broken of the feed hopper is set
Machine.
Background technique
Vertical shaft impact crusher is the commonly used equipment of building stones and mining manufacture field, is widely used in metal and nonmetallic
The industries such as ore, highway, water conservancy and hydropower and artificial sand making, main broken technique are divided into " stone-crash-stone " and " stone forges iron " two
Kind, in order to realize that the flexible conversion of two kinds of crushing process, the design of feed hopper need while having bypass flash and center feed
Function and the proportion adjustment for being able to achieve inlet amount.
Currently, to meet " stone-crash-stone " and " stone forges iron " both techniques, feed hopper mostly uses greatly cylinder or just more
Face body receiver bin, receiver bin border increase have material overflow port (or：Flash window) and regulating device is had, to reach estimated and overflow
Expect effect, needs to increase material stream, so that material is piled with receiver bin bottom, but this mode can generate a large amount of material stocks, flash effect
It is bad, it is broken to be not thorough, also increase body inertia and vibration.
The feed hopper of existing technical solution generally has cylinder and two kinds of regular polygon formula, in order to realize flash tune
Section, is that feed hopper is divided into feed hopper inner chamber body and feed hopper outer chamber two parts mostly, material overflow port is opened up in inner chamber body, and
Several flash adjustable plates, the corresponding material overflow port of each flash adjustable plate are set.Card slot is offered in flash adjustable plate periphery
Or location hole, in feed hopper material overflow port outer edge corresponding card slot or location hole are also opened up, passes through replacement card slot or bolt hole
The adjusting of material overflow port size is realized in position.
Applicants have discovered that：At least there is following technical problem in the prior art：
Realize the overflow of material, it is necessary to feed hopper first be accumulated into a large amount of materials, when carrying out flash adjusting, must first be stopped
Machine, operator enter in feed hopper, cleaning hopper in accumulate material, then one by one move replacement flash adjustable plate card slot or
Material overflow port is adjusted in location hole.Flash window adjustment process is cumbersome, time-consuming and laborious；According to scheduled card slot or it must determine
Position hole adjusting position, makes flash window size adjust accuracy not high, and due to windrow in hopper, brings not to operator
Just；It must first shut down and adjust afterwards, reduce production efficiency；Feed hopper is made of interior exocoel, and complicated integral structure, weight is big, production
It is at high cost.
