Description

Prevent the hopper of emanating

Technical field

The utility model belongs to the drawing mechanism of mixture, relates in particular to as preventing the hopper of emanating.

Background technology

In the rubble course of processing, the rubble of different size is normally transported to stockpile separately by belt transporter, and rubble is easy to occur segregation phenomenon in the process falling.

Material segregation refers to that large particle diameter material and small particle diameter material are assembled respectively under external force, causes the inhomogeneous phenomenon of inner materials.This is the material different due to particle diameter, its motional inertia is not identical yet, when mixture is being subject to after external force (as gravity) effect, the movement rate of large particle diameter material must be greater than the movement rate of small particle diameter material, thereby causes large small particle diameter feed separation to form segregation phenomenon.After material segregation, inner materials is inhomogeneous, and serious fineves such as (particularly) aggregate chips of the larger segregation of particle diameter, thereby has had a strong impact on the quality of product.

Therefore, be necessary to add a kind of device that prevents segregation at the defeated end of belt transporter.

Utility model content

The purpose of this utility model is to overcome the above-mentioned defect of mentioning and deficiency, and the one hopper that prevents from emanating is provided, and can effectively prevent the generation of material segregation phenomenon.

The technical scheme that the utility model is realized its object employing is as follows.

Prevent the hopper of emanating, comprise housing, middle part, described housing below is rotatably connected to the bin gate that is down " V " type, and discharging opening is divided into left discharging opening and right discharging opening by described bin gate.

Described bin gate middle part is fixedly installed dividing plate, and hopper is divided into left chamber and right chamber by described dividing plate.

Described dividing plate lower end is fixedly connected on bin gate middle part, and described dividing plate upper end is through housing and higher than edge on housing.

The junction of described dividing plate and bin gate is vertically provided with strengthening rib.

Middle part, described housing below is provided with bearing seat, and described bin gate is articulated with bearing seat.

The baffle plate that described bin gate is adapted by two plate shapes and discharging opening forms, and the angle between two baffle plates is 90 ° ~ 165 °.

In figure: plate, 1d-right panel, 1e-upper plate, 1f-lower plate, 2-bin gate, 3-dividing plate, 4-strengthening rib, 5-bearing seat after 1-housing, 1a-header board, the left plate of 1b-, 1c-.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Prevent the hopper of emanating, comprise housing 1 and be arranged on the bin gate 2 that housing 1 middle part, below is down " V " type.Discharging opening is divided into left discharging opening and right discharging opening by described bin gate 2.Described bin gate 2 is rotationally connected with housing 1, and as preferably, described housing 1 middle part, below is provided with bearing seat 5, and described bin gate 2 is articulated with bearing seat 5.

When rubble is when belt transporter unloads, because the stopping of bin gate 2, rubble is piled up on bin gate 2.When a side rubble is when heavier, bin gate 2 rotates to this side, and the discharging opening opening of this side increases, and the different rubble of particle diameter gathering unloads from the discharging opening of this side simultaneously, and even material has effectively been avoided the segregation of rubble.

Described bin gate 2 middle parts are fixedly installed dividing plate 3, and hopper is divided into left chamber and right chamber by described dividing plate 3.In the time that the bin gate 2 of a side is opened discharging, the rubble that particle diameter is larger can glide or roll, and dividing plate 3 has intercepted rubble and between left chamber and right chamber, rolled because of inclination or the rotation of bin gate 2, thereby has avoided segregation.As preferably, described dividing plate 3 upper ends are through housing 1 and higher than edge on housing 1.Described dividing plate 3 upper ends exceed the length of housing 1, and opening at a side bin gate 2, dividing plate 3 is while turning to the chamber of this side, be still advisable higher than housing 1 in dividing plate 3 upper ends.Like this, can effectively avoid gathering when more when hopper medium stone, hopper rotates rubble string in rear high-lying chamber and is rolled to the chamber of low level, has stopped the bin gate 2 of directly opening from this side from the defeated rubble dropping of belt transporter simultaneously and has discharged.

The junction of described dividing plate 3 and bin gate 2 is provided with strengthening rib 4.Described strengthening rib 4 can effectively increase the constant intensity between dividing plate 3 and bin gate 2.Described strengthening rib 4 vertically arranges, and has played the effect that guiding rubble falls simultaneously.Dividing plate 3 both sides are provided with at least two strengthening ribs 4.

The baffle plate that described bin gate 2 is adapted by two plate shapes and discharging opening forms, and the angle between two baffle plates is 90 ° ~ 165 °.Angle between two baffle plates has directly affected the size of discharging opening.The size of discharging opening is unsuitable excessive in the situation that meeting unloading performance, and less discharging opening can force rubble to be concentrated and draw off, and reduces segregation phenomenon and occurs.The particle diameter of coarse aggregate is conventionally between 4.75 ~ 31.5mm, and for making coarse aggregate can pass through smoothly discharging opening, and discharging opening is unsuitable excessive, and the angle between two baffle plates is 90 ° ~ 165 °.According to practice, the speed of comprehensive discharging, as preferably, the angle between two baffle plates is 130 ° ~ 155 °.

Concrete, described housing 1 is made up of header board 1a, rear plate 1c, left plate 1b and right panel 1d, and described header board 1a and rear plate 1c are surface plate, and described left plate 1b and right panel 1d are made up of the upper plate 1e vertically arranging and the intilted lower plate 1f in lower end.Therefore, it is large that described hopper forms a upper end open, and the device that lower ending opening is little has the capacity of temporary transient storage rubble.Described hopper top is divided into a cube, rubble herein provides enough pressure for discharging, it is inclined-plane that lower part also only has the left and right sides, the resistance that while having reduced discharging, rubble slides, therefore, the housing 1 of this structure, has increased the speed of discharging, play the effect that mixes rubble, effectively controlled the generation of segregation.This device is specially adapted to the windrow of bittulith, certainly, is also applicable to other similar windrows, as rubble etc.

As shown in Figures 2 and 3, in the time that the rubble weight of dividing plate 3 one sides is greater than opposite side, the bin gate 2 of a heavy side is opened, and the rubble of this side is concentrated and discharged a part.Now, because of the rubble weight saving of this side, dividing plate 3 turns to opposite side, and the bin gate 2 of opposite side is opened, and the rubble of opposite side is concentrated and discharged a part, so circulation.

The utility model is illustrated according to embodiment, is not departing under the prerequisite of present principles, and this device can also be made some distortion and improvement.It should be pointed out that all employings are equal to the technical scheme that the modes such as replacement or equivalent transformation obtain, and all drop in protection domain of the present utility model.
