Abstract

The utility model discloses a step sealing type material bin door and belongs to the field of feed machines. A cylinder drives a swinging arm to rotate, so that two semicircular bin doors assembled on a rotation shaft are turned over or placed flatly, the effects of material discharging and material sealing are achieved, and the problem that powder materials which easily flow are difficult to seal is solved. The step sealing type material bin door is characterized in that the two semicircular bin doors are vertically staggered on the rotation shaft to form a step turning plate, sealing bars are vertically staggered on the inner walls of bin door cylinders, the sealing bars have overlapped areas with a turning plate shaft, materials can not flow down from seams at the two ends of the turning plate shaft, and when the turning plate is placed flatly, the step turning plate is in tight contact with the sealing bars to seal the materials; when the turning plate is driven by the cylinder to rotate by a certain angle, the sealed materials can be quickly discharged. Compared with the prior art, the step sealing type material bin door has the advantages that sealing performance is good, the bin door is round, reducing is not needed when the bin door is connected with a round weighing hopper, the height of the device can be reduced, and cost is saved.

Description

Stepped sealed formula feed bin door

Technical field

The utility model relates to a kind of stepped sealed formula feed bin door that is applied to feed factory, belongs to feed manufacturing machine technical field.

Background technology

At present, known feed factory burden balance and the door of feed bin have board-like and simple and easy round turnover plate type of square lower turnover plate type, electric mortiser etc., square lower turnover plate type sealing is tighter, but structure relative complex, manufacture difficulty is large, need to justify feed bin or circle and claim bucket to become square opening discharging, make to claim bucket or feed bin manufacturing cost to rise; Electric mortiser is board-like not only to be had above-mentioned shortcoming but also pulls and pushes in process and often have partial material to leak at plate, therefore can only be applied on the feed bin that material fluidity is poor, accuracy requirement is not high; Simple and easy round turnover plate type has the single low cost and other advantages of the cylinder of manufacture, but poorly sealed, can only be used on the very poor or granular material of flowing power.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of stepped sealed formula feed bin door.

The technical scheme that the utility model adopts is: stepped sealed formula feed bin door is made up of the seam of door cylinder, sealing band, cutting plate, ladder turnover panel, rotating plate shaft, bearing, swing arm, cylinder or oil cylinder etc.The seam of door cylinder is to be welded to form by solid drawn pipe, flange, air cylinder support, bearing plate etc., upper flanges dish is connected with batch weigher bucket or feed bin, solid drawn pipe Central Symmetry has two circular holes so that rotating plate shaft passes, the bearing plate that circular hole external welding is made up of channel-section steel, air cylinder support is made up of channel-section steel welding, end has transfer ear, and cylinder connects by bearing pin and transfer ear strand, and cylinder can freely be rotated when flexible.Sealing band is two and bends to semicircle band steel band, symmetrical upper and lower zigzag weld is connected on steel pipe inner wall, when ladder turnover panel is closed and sealing band close contact seal material, cutting plate is ridge by two block plates and is welded on retrousse ladder turnover panel, its effect is to reduce the resistance that turnover panel upwards stirs, when blowing, cylinder promotes swing arm, and swing arm is rotated and driven rotating plate shaft rotation to make ladder turnover panel upset 80 degree, and material gushes from feed bin door.

Compared with prior art, the beneficial effects of the utility model are not only good seals of this door, and door is rounded, with claim bucket or bulk tank is connected simply, equipment manufacturing cost is low.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further illustrated: stepped sealed formula feed bin door is by door cylinder seam (1), sealing band (2), cutting plate (3), ladder turnover panel (4), rotating plate shaft (5), bearing (6), swing arm (7), the compositions such as cylinder (8), door cylinder seam (1) is by solid drawn pipe, flange, air cylinder support, bearing plates etc. are welded to form whole door main body framework, upper flange plate is connected with claiming bucket or feed bin, the equipment connection such as lower flange and mixer, turnover panel, other parts such as cylinder are all arranged on door cylinder, sealing band (2) is two and bends to semicircle band steel band, symmetrical upper and lower zigzag weld is connected on door cylinder inwall, when door is closed, ladder turnover panel (4) keeps flat with sealing band (2) and contacts the effect of playing sealants, because the upper and lower interconnected and middle rotating plate shaft of sealing band (2) is all educated overlapping region, runny material can not be flowed down from rotating plate shaft two ends seam, cutting plate (3) is ridge-shaped by two block plate docking and is welded on retrousse ladder turnover panel (4), its effect is to reduce the resistance that turnover panel upwards stirs, cylinder when blowing (8) promotes swing arm (7), swing arm (7) rotation drives rotating plate shaft (5) to rotate in bearing (6) and makes ladder turnover panel (4) upset 80 degree, material gushes from feed bin door.

Claims

1. a stepped sealed formula feed bin door, in door cylinder, two semicircular door is fixed in rotating shaft, rotate and make door upset and keep flat by cylinder or hydraulic oil cylinder driving swing arm, play the effect of discharging and sealants, it is characterized in that: two semicircular door staggers to be disposed at by height and in rotating shaft, forms notch cuttype turnover panel, the upper and lower interconnected and middle rotating plate shaft of sealing band has overlapping region, runny material can not be flowed down from rotating plate shaft two ends seam, by ladder turnover panel and sealing band close contact sealants.

2. stepped sealed formula feed bin door according to claim 1, it is characterized in that: utilize various materials to have its flowing power slope angle of repose, form sealing arrangement by ladder door and interconnected sealing band and make the material sealing all be less than its intrinsic slope angle of repose at each overlapping gap place flowing angle, thereby play sealing function.
