Abstract
The utility model discloses a spiral material conveying device, which is simple in structure, low in fault rate and reliable in operation. The spiral material conveying device comprises an U-shaped cover and a T-shaped cover, the U-shaped cover and the T-shaped cover are sleeved on an end shaft of a spiral rod and mutually covered on a bearing device and the end of the spiral rod oppositely respectively, and the T-shaped cover is simultaneously fixedly connected onto a bearing seat and a sleeve of the spiral rod.
Description
Technical field
The utility model relates to a kind of device for transporting objects, relates in particular to a kind of spiral material feedway that is used for the tight mouthful machine of firecrackers.
Background technology
The belt-type feedway is a kind of the most common device for transporting objects, but a lot of occasions and special material are not suitable for using the belt-type feedway, this just need use drawing-in type or screw conveyor, for its maximum problem of screw conveyor is that material is easy to enter in the drive disk assembly and causes the damage of drive disk assembly, particularly having corrosive material or hard powder, is like this especially.As be used for the solid flashing composition screw conveyor of tight mouthful of machine of firecrackers, and the solid flashing composition material is easy to enter drive disk assembly and causes parts to damage, and particularly for upwards or tilting when making progress convey materials, the bearing failure that is positioned at the screw rod bottom is even more serious.Will change bearing in common several days No. one time, both increase maintenance capacity and cost, influence is produced again, also causes the waste of material simultaneously.
Summary of the invention
The purpose of this utility model is the problem that exists at prior art, and a kind of spiral material feedway is provided, and this transport conveyor constructions is simple, and fault rate is low, and is reliable, and maintenance capacity is little.
The technical solution of the utility model comprises interconnective screw rod and bearing arrangement, is provided with protective device between described screw rod and the bearing arrangement.
Described protective device comprises that the one or more protective covers that are sheathed on the screw rod constitute between described bearing arrangement and screw rod.
Be that described protective device comprises that two protective covers constitute, described two protective covers oppositely are being sheathed on the screw rod axle between bearing arrangement and the screw rod mutually.
Described two protective covers are cover cap or be a tubular or U-shaped cover on bearing arrangement through a packing ring cover cap wherein, cover cap in or be T shape cover by being located at concave ring groove cover cap on the screw rod in the screw rod end.
Described cover cap is fixedly connected between screw rod sleeve and the bearing seat simultaneously in the cover of the T shape on the screw rod.
The utility model is simple in structure, no matter be that hard powder or corrosive property material can not enter in the transmission device during work, can protect drive disk assembly not to be damaged; maintenance capacity is little; can not cause the waste of material, long service life has not only improved production efficiency but also can save cost.Be applicable to various spiral materials conveyings.For vertical or when being inclined upwardly the formula mass transport protective effect to the bearing of screw rod bottom excellent in important, be specially adapted to produce the regenerative apparatus of solid flashing composition of tight mouthful of machine of fireworks.
Description of drawings
Fig. 1 is the utility model structural representation.Fig. 2 is the utility model mounting structure scheme drawing.
The specific embodiment
Now also the utility model is described in further detail in conjunction with the accompanying drawings by embodiment.Present embodiment is the application example of firecrackers tight (putting in order) mouthful machine, and this protective device 23 is located at the tightly lower end of the screw conveyor 24 of the material regenerative apparatus of mouthful machine 7 of firecrackers.As illustrated in fig. 1 and 2, be sheathed on by its center through hole that U-shaped cover 15 openings on the screw rod 19 1 end end axles 11 are crimped on the internal axle sleeve 13 of bearing arrangement to bearing arrangement one side, by the ring-shaped step on sleeve pipe or packing ring 14 and the spiral rod end axle 11 and above the end axle 11.T shape cover 16 partly is placed in the end that concave ring groove 17 inner covers on the screw rod 19 are placed on screw rod 19 by its center through hole by ring pipe.The transverse slat partial fixing of T shape cover 16 or be fixedly connected on simultaneously on screw rod sleeve 18 and the bearing seat 12 by bolt.
Screw rod 19 is pushed down U-shaped cover 15, packing ring 14, bearing arrangement internal axle sleeve 13 successively by the step of its end axle 11 and is supported on the bearing arrangement and rotates with bearing.Like this, when screw rod 19 rotary works, the secondary protection of process T shape cover 16 and U-shaped cover 15 can prevent that the materials in the screw rod sleeve 18 from entering in the bearing, avoids causing the damage of bearing arrangement.
