Abstract
The utility model relates to a dust absorption type angular direction polishing machine which is composed of a motor, speed reducing box, grinding wheel plate, a centrifugal fan, a filter bag and an overturn type protecting cover. The utility model is characterized in that the centrifugal fan for sucking dust is installed between the speed reducing box and the grinding wheel. The filter bag is connected to the exit of the centrifugal fan. The protecting cover is arranged round the grinding wheel plate. The utility model has the advantages of reasonable structure and convenient operation, is a more ideal exclusive use electric tool for removing rust and grinding, the dust of construction can be effectively excluded, working environment can be prevented from being polluted, and the efficiency of dust suction can reach more than 95 percent.
Description
The utility model provides a kind of and has been applicable to that plane and groove eliminate rust, the special electric instrument of polishing, i.e. dust-collecting type electric angle grinder.
In the rust cleaning polishing construction of closed container such as existing metal can, pressure pipeline and weld groove, owing to produce a large amount of dust, the severe contamination working environment influences the healthy of operating efficiency and workman.The applicant's the utility model patent dust-collecting type electric wheel sander (patent No.: 88208482.8), be not suitable for the polishing of weld groove though can solve dust pollution question in the grinder buffing well.And the horizontal electric angle grinder that generally uses does not both at home and abroad all solve dust pollution question effectively.
The purpose of this utility model is will provide a kind of promptly can carry out the polishing of plane and groove, has the electric angle grinder of dust-absorbing filtering function again simultaneously.It can make the dust that produces in the polishing of plane and groove in time get rid of, for the good working environment is created in construction.
The dust-collecting type electric angle grinder of the utility model indication improves existing horizontal electric angle grinder, the centrifugal blower that is useful on dust suction promptly has been installed between reduction box and emery wheel, the outlet of blower fan connects a filter bag, filter bag can be collected dust and can discharge air, and protective cover is housed around grinding wheel.The protective cover framework is connected with vacuum cleaner and is axle with the junction, and protective cover can stir, to adapt to the needs of the face of tying and groove.The protective cover top is provided with observation window, and observation window can adopt material transparent such as organic glass material to make.The overskirt of protective cover and working face contact portion can adopt the soft material of rubber slab and so on, to guarantee having good sealing to contact with working face, prevent the dust diffusion.
The utility model compared with prior art, outstanding feature is the dust that can get rid of effectively in the construction, prevents the pollution of working environment, dust collection efficiency reaches more than 95%, has improved working environment, has protected effectively that the workman's is healthy.This dust-collecting type electric angle grinder is rational in infrastructure, and is easy to use.Be a kind of more satisfactory rust cleaning, polishing special electric instrument.
The utility model can also be given more detailed description in conjunction with following accompanying drawing.
Fig. 1 is the structural representation of dust-collecting type electric angle grinder.
Fig. 2 is that A among Fig. 1 is to the structural representation of protective cover.
When polishing, rust cleaning construction, operating personnel's handheld electrical machinery shell (1).Driven by motor reduction box (2) output shaft (8).Be fixed with centrifugal blower volute (7) on the reduction box (2).Grinding wheel guard (10) is installed on the spiral case (7).Output shaft (8) drives impeller (9) and grinding wheel (6) in the coaxial spiral case.The dust that polishing produces is sealed by protective cover (5), and protective cover framework (4) links with centrifugal blower volute (7), and the protective cover framework (4) that can stir is to realize stirring with the axle (12) of junction.Operating personnel can see the polishing situation from observation window (3).Dust sucks and delivers in the filter bag (11) through spiral case, and air is discharged from filter bag.When the long-pending full dust of filter bag can, draw back zip dust outwelled.Dust sucks filter efficiency more than 95%.
