Said structure according to the utility model; Scraper plate is connected on the scraper chain through connecting panel; So, needing leak free partly is exactly the horizontal surface board, for having certain thickness sheet material; Trench structure through leaving tolerance clearance with this horizontal surface board constitutes easy labyrinth seal structure, can satisfy the leakage material that material can not occur in transmission side.For the selection in gap, mainly can select according to the proterties of material, such as being graininess, the gap should be not more than 1.5 times of the material particles diameter so, if be cotton-shaped, the gap can be big slightly, as long as cotton-shaped material is not wound into scraper chain.Labyrinth seal structure is a representative type noncontact movable sealing structure, owing to do not come in contact, sealing member can not wear and tear usually, and prolong service life greatly.
Above-mentioned conveyer side seal structure, said gap is 3 ~ 5mm.
Above-mentioned conveyer side seal structure, said trench structure are provided with one away from the limit of scraper plate and are used for and the horizontal flange of frame bonded assembly.
Above-mentioned conveyer side seal structure, said horizontal flange turns up to notch.
Above-mentioned conveyer side seal structure is provided with brace panel between said flange and limit, place.
The limit that above-mentioned conveyer side seal structure, said trench structure are positioned at the scraper plate side is connected with a vertical backplate, with to extending below the limit, place, and is connected through separable joint spare between this backplate and institute connection side.
Above-mentioned conveyer side seal structure, said connecting panel are L type structure, and its stile is and said scraper chain bonded assembly part.
Description of drawings
Fig. 1 is a kind of connection structure of slat conveyer scraper plate and scraper chain.
Fig. 2 is a kind of conveyer side seal structure according to the utility model.
Among the figure: 1, scraper plate, 2, connecting panel, 3, roller, 4, backplate, 5, cover plate, 6, brace panel, 7, stay bearing plate, 8, frame.
The specific embodiment
With reference to explanation accompanying drawing 1; Be the connection structure of a kind of double chain conveyor middle scraper and messenger chain, be connected to scraper plate through connecting panel 2 on the picking up the ears of roller chain of both sides, in order to be beneficial to the groove that is formed for carrying; Connecting panel has the horizontal surface board, is used for extending connecting.
Referring to a kind of conveyer side seal structure shown in the Figure of description 2; Be used for double chain conveyor; The scraper plate two ends are connected on the scraper chain through the connecting panel 2 with horizontal surface board; On the frame of scraper plate both sides, be provided with the grooved parts of back-off, be used to hold the cochain limit, and the upper surface of horizontal surface board of lower edge and connecting panel that trench structure is positioned at the limit of scraper plate side leaves the gap.
Here use the notion of shaped steel, certainly, dependency structure also can directly use shaped steel, such as trench structure, directly removes to use shaped steel, and two limits of shaped steel are used to hold one side of scraper chain straight down in the groove, and the waist of channel-section steel forms back-off structure in the above.Certainly, be in the needs of installation, the main body of trench structure is a grooved, and supplementary structure and agent structure can global formations, also can adopt other annexes of welded structure welding.
The direct use of channel-section steel, it can be used for fixing on one side, and need the limit bonded assembly structure with channel-section steel this moment, such as vertical panel.Preferable selection is the supporting construction with reference to roller chain, and shown in accompanying drawing 2, roller 3 is supported on the level version; Form friction of rolling, correspondingly, trench structure is if adopt the words of channel-section steel; The connection technology that is complementary is welding, and forms cantilever beam, and Joint strenght is relatively poor.If the raising Joint strenght must add other attaching parts again, therefore, to be said trench structure be provided with one away from the limit of scraper plate to preferable structure is used for and the horizontal flange of frame bonded assembly, and formation face is connected, and Joint strenght is high.
So further, said horizontal flange turns in notch and the two kinds of situations of turning up, in turn over and also can be used for connecting, but assembly difficulty is big, and possibly conflict with roller, therefore preferably adopts the structure of turning up, and forms bigger installing space in the groove.
Better selection is referring to Figure of description 2, is provided with brace panel 6 between said flange and limit, place, can improve Joint strenght greatly, in addition, because the existence of brace panel 6 can also form the tractive structure, has improved the rigidity of trench structure.
About the selection in gap, preamble is explained, need take all factors into consideration all kinds of materials with reference to the proterties of material; This programme lays particular emphasis on the conveying of cotton-shaped material, such as unginned cotton, for the material of other types; Can adopt more corresponding structure, all kinds of after all hermetically-sealed constructions all have its occasion that more is suitable for, therefore; When application laid particular emphasis on cotton-shaped material, said gap was preferably 3 ~ 5mm, can satisfy the conveying of cotton-shaped material fully.Such as unginned cotton, flowing power is poor, unlike granular material, certain fluidity is arranged.Certain cotton-shaped material also may embed said gap in course of conveying, therefore, maximum can not surpass 5mm, prevents the embedding of material; Unsuitable too small, scraper plate is not a smooth running after all, and certain beating arranged yet, and therefore, minimum should not be less than 3mm.
The limit that the maintenance of hermetically-sealed construction for ease, said trench structure are positioned at the scraper plate side is connected with a vertical backplate 4, with to extending below the limit, place, and is connected through separable joint spare between this backplate and institute connection side.Comparatively speaking, body one length of side of trench structure, on one side short, the convenient connection, and the backplate side of easy abrasion can regularly replace, maintainable good.
Preferably, said connecting panel 2 is a L type structure, and its stile is and said scraper chain bonded assembly part, makes things convenient for the setting of hermetically-sealed construction.Typical case's representative of L type structure is an angle steel, can select equal angle for use, also can select L-bar according to the stile of L type structure and the length of horizontal surface board, and the choice is bigger.Certainly,, also can select the steel plate bending part in order to practice thrift cost, lower than shaped steel cost.
