Abstract

The invention relates to an apron conveyer return device comprising a cleaning plate. A rib plate is welded on an apron; the cleaning plate is connected with the rib plate; a connecting side plate is fixed on the bearing box of a return shaft; a return arc plate is connected with the connecting side plate; a sliding rod on the connecting side plate is penetrated in a guide chute fixed on a shell. The invention has the advantages that when materials are conveyed on the upper layer, the rib plate and the cleaning plate can greatly improve the conveying efficiency of equipment, and the advantage is especially obvious under the condition of conveying at an angle; when the apron reaches the return section of the lower layer, the rib plate and the cleaning plate bring material deposits on a bottom plate to the tail. The material deposits brought by return are returned to a conveying layer under the guide of the return arc plate. The installation space of the equipment does not need to be enlarged, and simultaneously, the height of the equipment shell does not need to be increased to independently install a driving device and a traction facility to carry out cleaning in the whole cleaning and return process does not, but more importantly, the cleaned materials are automatically returned to the conveying layer.

Description

Apron conveyer return device

Technical field

The invention belongs to material transfer equipment and make the field, be specifically related to the material-returning device of apron conveyer, after be that material, material adhesion discharging are clean because of leaking on the apron conveyer backhaul layer, airborne dust etc. causes the equipment bay buildup, buildup is returned to a kind of device of transfer layer (upper strata), can be played the effect of cleaning simultaneously.

Background technology

At present, walk the serial equipment of material in load transfer device field especially upper strata, because of charge mostly be hopper or dissepiment overlaps, in charging with walk in the process of material, very easily cause material to drain on backhaul layer or the equipment bay from the upper strata, this situation shows particularly seriously when equipment has bending section, tilting section.Cause the reason of backhaul layer or equipment bay buildup to also have a lot, in charging, discharging and course of conveying, easily cause airborne dust to pile up backhaul layer or equipment bay such as the material of being with airborne dust; Also carry having under the moisture situation such as sticking material or light weight material, material often sticks on the dissepiment plate (bucket) and can not unload by deadweight, and shakes off in the backhaul process on backhaul layer or equipment bay or the like.In view of above situation, special-purpose clearing apparatus is installed additional to equipment in many device fabrication producers or research institution, and this has not only proposed requirements at the higher level to installation space, the device fabrication cost will increase the device of the omnidistance base plate cleaning of nearly 1/3(), and use cost also increases about 1/4; Clearing apparatus patent (the application number: 200910181347.X) of the apron conveyer of nearest application, can clean rough dissepiment surface, but do not possess the base plate cleaning function, only solved the cleaning of discharging, other still can not finely solve as the base plate buildup that charging, airborne dust etc. causes, and need increase a series of auxiliary facilities such as driving device in addition, use cost also still can not reduce.

Summary of the invention

Purpose of the present invention provides a kind of installation space that neither takies in addition, and the interaction energy that also can reduce production and use cost, transport efficiency height, has a cleaning equipment base plate turns back to buildup the apron conveyer return device of feed end (transfer layer).

The object of the present invention is achieved like this: a kind of apron conveyer return device, comprise cleaning board, and gusset is welded on the dissepiment, and cleaning board is connected with gusset; Connect side plate and be fixed on the bearing box of backhaul axle, returning charge arc plate with is connected the side plate connection, the slide bar on the connection side plate is through in the guide chute that is fixed on the housing.

The invention has the beneficial effects as follows: when the convey materials of upper strata, gusset and cleaning board can significantly improve the equipment transport efficiency, and advantage is particularly remarkable under the situation that the band angle is carried; When dissepiment was gone to lower floor's backhaul section, gusset and cleaning board were taken back afterbody with the buildup on the base plate.The buildup of under the guiding of returning charge arc plate backhaul being brought is returned transfer layer (upper strata).Whole cleaning and returning charge process need not enlarge installation space, and the while also needn't increase the apparatus casing height and actuating device is installed separately below and be drawn facility and clean, and the more important thing is that the material that will clean automatically returns to transfer layer (upper strata).

The specific embodiment

The structure of invention is as follows: a kind of apron conveyer return device, comprise cleaning board 1, and gusset 2 is welded on the dissepiment, and cleaning board 1 is connected with gusset 2; Connect side plate 3 and be fixed on the bearing box 6 of backhaul axle, returning charge arc plate 4 with is connected side plate 3 connections, the slide bar on the connection side plate 3 is through in the guide chute 5 that is fixed on the housing.

Principle of work of the present invention is as shown in Figure 1: by the round and round part of apron conveyer, utilize the cleaning board 1 that is contained on the dissepiment during lower floor backhaul, buildup on the equipment bay scraped sweep to afterbody, under the guiding of returning charge arc plate 4, material is turned back to transfer layer (upper strata).Forming on-cycle like this scrapes and sweeps+action of returning charge and finish the task of carrying smoothly.

In Fig. 2 general assembly drawing, gusset 2 is welded on the dissepiment, and cleaning board 1 and gusset 2 bolt togethers can make things convenient for the gap and the replacing of adjusting and base plate, returning charge arc plate.Connect side plate 3 with bearing box 6 and returning charge arc plate 4 all bolt together get up, bearing seat is installed on the axle, can be when regulating the chain degree of tightness, under the support of guide chute 5 and guiding, move with tailing axle.Need not independently actuating device and space, promptly realized the overall process of base plate cleaning and returning charge.

Fig. 3 is the A-A cutaway view of Fig. 1, has further represented the assembly relation of material-returning device from the angle of overlooking.Cleaning board 1 can be by the gap of actual requirement adjusting with returning charge arc plate.Returning charge arc plate 4 is connected with bearing box 6 by connecting side plate 3, and the slide bar that connects simultaneously on the side plate 3 is through in the chute of the guide chute 5 that is fixed on the housing, when whole device is mobile with tailing axle, guarantees that the relative position of returning charge arc plate and base plate and axle is constant.

Fig. 4 backhaul axle assembly drowing, bearing box 6 and plain bearing 8 screw tightening, bearing are assemblied in the last end of axle and locate by an axle cochain position of wheel shaft shoulder, fix with back-up ring 7 for other one section, and machined piece is few, and is easy to implement.

Fig. 5 is a returning charge arc plate outside drawing, two blocks of semi-moon shaped plates are arranged, both played the setting effect of strengthening the arc plate, again can be from the two ends backgauge of gusset on the dissepiment, form a relative box, thereby buildup is served transfer layer with dissepiment, connection side plate 3, wear-resisting cleaning board 1.
