Abstract
The utility model relates to a separated drum cover capable of avoiding incomplete material pouring and overflow of dust. The separated drum cover adopts the connecting mode: a push rod is in interference fit with a bearing; and a cover board is in interference fit with the bearing. A push rod motor makes the push rod, the bearing and the cover board to do horizontal motion; and when a drum rotates, the cover board and a bearing outer ring do circumferential motion under the action of the friction force generated by rubber on the cover board and the wall of the drum. The drum cover can effectively avoid the phenomena of incomplete material pouring influenced by the drum cover and overflow of the dust during rotation of the drum.
Description
Affiliated technical field
The utility model relates to a kind of locking device of rotary drum equipment, especially adopts the mode of separating with rotary drum.
Technical background
At present, should be on rotary drum according to national standard " assay method of GB/T2006-2008 coke mechanical strength " rotary drum lid, and factory's rotary drum commonly used, for convenient in application, rotary drum is also nonocclusive.With regard to national standard, under lid and the situation of rotary drum one, rotary drum is through four minutes rotation, and when stopping, because rotation error, the rotary drum mouth can not guarantee vertically downward accurately, thereby causes situation such as batch turning is not clean to take place; Under the not encapsulation situations that factory uses always, rotary drum is in rotary course, because material produces a large amount of dust to the friction and the effect of impact of rotary drum, along with the rotation of rotary drum, dust is gushed out, and has caused destruction to working environment, and the result is measured in influence either way.
Summary of the invention
Do not reach the phenomenon that dust is gushed out only in order to solve the batch turning that rotary drum occurs under above-mentioned two kinds of situation; The utility model provides a kind of mode of rotary drum connection cover; Not only avoid rotary drum lid must opening direction vertically downward, and solved the dust that the does not seal rotary drum problem of gushing out
The utility model is for solving the problems of the technologies described above, and the technical scheme that is adopted is: rotary drum is separated with the rotary drum lid, and before will being rotated after the rotary drum charging, the rotary drum lid is closed with rotary drum; When drum rotating, push-rod electric machine makes push rod, bearing, cover plate do horizontal movement; The frictional force that rubber on the cover plate and rotatory drum wall produce moves in a circle cover plate, bearing, and rotary drum covers with drum rotating, stops dust to gush outward: when the rotation completion, the rotary drum lid separates rotary drum batch turning immediately with rotary drum.
The beneficial effect of the utility model is, it is unclean to avoid influence owing to the rotary drum lid that batch turning takes place, and eliminates drum rotating simultaneously and the dust that the produces phenomenon of gushing out.

Fig. 2 is in the drum rotating process, and push-rod electric machine (3) makes the state diagram of rotary drum lid (2) and rotary drum (1)
Fig. 3 be rotary drum under the batch turning situation, push-rod electric machine (3) makes the state diagram of rotary drum lid (2) and rotary drum (1)

The specific embodiment
Rotary drum among Fig. 1 (1) rotation 70 degree connect material, and rotary drum lid (2) is away from rotary drum (1), connect material finish after, rotary drum (1) recovers horizontal level.
Rotary drum among Fig. 2 (1) horizontal positioned is about to be rotated, and the motion principle of Fig. 4 rotary drum lid is: push rod (1) adopts interference fit with bearing (2), cover plate (7) with bearing (2); Its motion principle is: push-rod electric machine travels forward push rod (1); Rely on push rod (1) and the interference fit of bearing (2) and the drag effect of the shaft shoulder, drive bearing (2) and travel forward, bearing (2) and cover plate (7) interference fit; Bearing (ball) cover (4) is in the fastening effect of bolt (5) in addition; Drive cover plate (7) and travel forward, when cover plate (7) stops horizontal movement with rotatory drum wall (9) when closely contacting, thus the sealing of realization rotary drum; When drum rotating, rely on the frictional force of rubber that cover plate (7) edge inlays and rotatory drum wall (9) generation, make cover plate (7) with rotary drum around the axle circular motion, thereby avoided the flour dust overflow phenomenon.
Among Fig. 3,, be about to carry out batch turning when rotary drum (1) rotation stops; The motion principle of Fig. 4 rotary drum lid is: push-rod electric machine moves push rod (1) backward, relies on push rod (1) and the interference fit of bearing (2) and the drag effect of bearing jump ring (3), drives bearing and moves backward; The drag effect of the port of bearing (2) and cover plate (7) interference fit, cover plate (7); Cover plate (7) is moved with bearing (2) backward, thereby the rotary drum lid separate the rotary drum batch turning with rotary drum.
Claims (3)
1. a separate type rotary drum lid is made up of push-rod electric machine, bearing, bearing jump ring, bearing (ball) cover, bolt, cover plate, rubber, and it is characterized in that: push-rod electric machine makes push rod, bearing, cover plate do horizontal movement; The frictional force that rubber on the cover plate and rotatory drum wall produce moves in a circle cover plate, bearing.
2. rotary drum lid according to claim 1 is characterized in that: push rod on the push-rod electric machine and bearing interference fit, and bearing and cover plate interference fit, bolt is fixed bearing (ball) cover and cover plate.
3. rotary drum lid according to claim 1, it is characterized in that: side edge thereof connects rubber.
