Abstract
The utility model discloses an intermediate bearing device of a spiral conveyor. The device comprises two flanges respectively arranged at the connecting ends of two delivery pipe slots, after the two delivery pipe pipes are connected, an annular slot provided with an opening facing the inner parts of the delivery pipe slots is formed between the two flanges, and a wearable support ring is arranged in the annular slot; the wearable support ring and the annular slot are subjected to clearance fit, the excircles of the spiral blades on a spiral shaft are subjected to clearance fit, and the inner wall of the wearable support ring is higher than the inner walls of the delivery pipe slots. The intermediate bearing device of the spiral conveyor provided by the utility is a middle bearing device, which integrally effectively supports the connection between the two delivery pipe slots of the spiral conveyor, and effectively reduces the radial run-out of the spiral blades. When the spiral blades move, the wearable support ring synchronously rotates to provide the support and can not be simultaneously locked, so that the pivoting friction force of the spiral shaft can be reduced; furthermore, the spiral blades can not be broken by the device, a delivery channel is not occupied, the smoothness of the feeding channel can be guaranteed, and the material blocking can be effectively prevented, so that the device can be guaranteed to stably and reliably operate.
Description
Technical field
The utility model relates to conveyer manufacturing technology field, especially a kind of auger loader middle bearing device.
Background technology
When auger loader convey materials, mostly adopt open type to carry tube seat, in the middle of installing, underslung bearing need disconnect helicallobe, and middle underslung bearing also takies spiral conveying passage, easily causes feed blocking, for prevent that feed blocking from using no or little conventional middle underslung bearing as far as possible; While carrying some material, need adopt hermetic type to carry tube seat, conventional middle underslung bearing cannot be installed in screw shaft middle part.
In the time that auger loader length is longer, while not having middle bearing support can cause helicallobe to rotate, radial runout is very large, and friction drag is large, thereby causes equipment operation steadily not fragile.
Utility model content
The utility model, for the deficiencies in the prior art, proposes a kind of auger loader middle bearing device, and entirety is carried tube seat junction for two of auger loaders effective support is provided, and effectively reduces the radial runout of helicallobe.When helicallobe running, wear-resisting support ring synchronously rotates, provide support simultaneously not stuck, reduce screw shaft pivoting friction resistance, and this device need not disconnect helicallobe, do not take conveying passage, guarantee that conveying passage is smooth and easy, can effectively prevent feed blocking, thereby the equipment that guarantees operates steadily reliably.
In order to realize above-mentioned utility model object, the utility model provides following technical scheme:
A kind of auger loader middle bearing device, comprises and is arranged on respectively two two flanges carrying tube seat coupling end,
After two described conveying tube seats connect, between described two flanges, form the circular groove of opening surface to described conveying tube seat inside,
Wear-resisting support ring is installed in described circular groove, helicallobe cylindrical free-running fit on described wear-resisting support ring and described circular groove and screw shaft.
Further, the inwall of described wear-resisting support ring is higher than the inwall of described conveying tube seat.
A kind of auger loader middle bearing of the utility model device, entirety is carried tube seat junction for two of bolt conveyers effective support is provided, and effectively reduces the radial runout of helicallobe.When screw shaft running, wear-resisting support ring synchronously rotates, provide support simultaneously not stuck, reduce screw shaft pivoting friction resistance, and this device need not disconnect helicallobe, do not take conveying passage, guarantee that conveying passage is smooth and easy, can effectively prevent feed blocking, thereby the equipment that guarantees operates steadily reliably.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of auger loader middle bearing device described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
A kind of auger loader middle bearing device as shown in Figure 1, is broken as two by helical feed tube seat in need support place and carries tube seat 1, carries the outside of tube seat 1 coupling end all to weld a flange 3 at these two,
Carry tube seat 1 to pass through, after flange 3 and bolt connection, between two flanges 3, to form opening surface to the circular groove of carrying tube seat 1 inside for two,
Wear-resisting support ring 4 is installed in circular groove, and helicallobe cylindrical free-running fit on wear-resisting support ring 4 and circular groove inwall and screw shaft 2, can suitably freely rotate.
The inwall of wear-resisting support ring 4, higher than the inwall of carrying tube seat 1, only contacts helicallobe outside face on screw shaft with wear-resisting support ring inwall, do not contact with carrying tube seat inwall.
When this device uses, entirety is carried tube seat 1 junction for two of bolt conveyers effective support is provided, and effectively reduces the radial runout of helicallobe.When screw shaft 2 turns round, wear-resisting support ring 4 synchronously rotates, wear-resisting support ring 4 inwalls provide support helicallobe outside face on screw shaft 2, prevent that helicallobe outside face from contacting with carrying tube seat 1 inwall, thereby reduce the friction drag of screw shaft 2 while rotating, and this device need not disconnect helicallobe, not take conveying passage, can effectively prevent feed blocking, thereby guarantee the steadily reliable of equipment operation.This apparatus structure is simple and practical, and cost of manufacture is lower.
Claims (2)
