Abstract
The utility model relates to a drum screen. The drum screen comprises a base plate, a support seat, a triangular plate and first support wheels, wherein the support seat is arranged on the base plate, the triangular plate is arranged on the support seat through a support shaft, and the first support wheels are arranged on the triangular plate through shafts and are connected with a screen cylinder in a sliding way. According to the drum screen, flexible force is additionally applied between the screen cylinder and the first support wheels, so that hard shocking between the traditional single support wheel and the screen cylinder is avoided so as to prevent the service life of the screen cylinder from shortening, and long-time hard stress on the single support wheel is further reduced to cause reduction on the service life of equipment.
Description
Technical field
The utility model relates to the rotary screen of domestic rubbish disposal, particularly relates to the rotary screen that the location is taken turns in use six.
Background technology
Domestic known rubbish screens employed rotary screen at present, is traditional four-wheel location rotary screen, promptly by each two of four support wheels front and back, locatees the rotary screen screen drum.In operation process,, strengthens traditional rigid localization method owing to producing support wheel resonant frequency in operation process, the vibrations between inelastic protection screen drum and the support wheel, and shortened service life.
Summary of the invention
The purpose of the utility model is the defective to prior art; A kind of rotary screen is provided; Big in order to solve the resonant frequency that produces owing to the four-wheel location in the prior art, inelastic protection is by the rigid friction vibrations that produce between effect of screen drum gravity and the roller, the problem that shortens service life.
For realizing above-mentioned purpose, the utility model provides a kind of rotary screen, and said rotary screen comprises: base plate; Supporting seat is arranged on the said base plate; Set square is arranged on the said supporting seat through back shaft; First support wheel, axle is located on the said set square, slides to connect with screen drum and establishes.
Said rotary screen also comprises: second support wheel, slide to connect with screen drum and establish.
Said first support wheel is two.
The utility model beneficial effect is following: increase i.e. soft stressed between first support wheel of screen drum and driven pulley, thereby prevent that single in the past support wheel and the rigid vibrations of screen drum from causing the reduction of screen drum life-span.Reduced the rigid stressed life-span reduction that causes equipment of the long-term wheel of single support wheel equally.
Description of drawings
Through accompanying drawing and embodiment, technical scheme of the present invention is done further detailed description below.
Fig. 1 is the structural representation of the utility model rotary screen.
The specific embodiment
The utility model rotary screen is a domestic rubbish disposal equipment, is intended to improve rotary screen service efficiency and life-span.
Like Fig. 1 is the structural representation of the utility model rotary screen.Said rotary screen comprises: supporting seat 1, first support wheel (2,3), bolster 4, second support wheel 5, screen drum 6, set square 7.
Supporting seat 1 is arranged on the said base plate 10; Set square 7 is arranged on the said supporting seat 1 through bolster 4; First support wheel (2,3), axle is located on the said set square 7, slides to connect with screen drum 6 and establishes.Said rotary screen also comprises: second support wheel 5, slide to connect with screen drum 6 and establish.In the present embodiment, said first support wheel (2,3) is preferably two.At this, first support wheel is not limited to use two shown in the present embodiment.Shown in first support wheel (2,3) adopt common roller or other to have the wheel of the slaved operation of can be used as.
Supporting seat 1, first support wheel (2,3), bolster 4, set square 7 these 5 parts have replaced the single support wheel that uses as driven pulley in the tradition.Second support wheel 5 is driving wheels, is used to receive power drive screen drum 6 and rotates.First support wheel (2,3) is used to receive screen drum 6 and rotates the frictional force brought and the pressure radially of screen drum 6.Set square 7 is used to receive the pressure that first support wheel (2,3) conduction comes.Supporting seat 1 is used for receiving through bolster 4 pressure of set square 7.
Set square 7 three end perforates connect bolster 4 and first support wheel (2,3) respectively; When the screen drum 6 of rotary screen rotated, the gravity right side was stressed in second support wheel 5, and the left side is stressed in first support wheel (2; 3), first support wheel (2,3) is stressed to set square 7; Set square 7 is stressed in bolster 4, can in the gravity angular range of the screen drum 6 of rotary screen, swing increase soft stressed between set square 7 and the bolster 4.Increase soft stressed between screen drum 6 and this 5 parts of rotary screen.
During concrete work, when having the rubbish of the screening treated in the screen drum 6 of rotary screen, driving wheel 5 drives screen drums 6 and rotates, and carries out the screening of rubbish.Second support wheel 5 is stressed, and left side first support wheel (2,3) is stressed, and first support wheel (2,3) is stressed to set square 7, and set square 7 is stressed in bolster 4.Can in the gravity angular range of the screen drum 6 of rotary screen, swing increase soft stressed between set square 7 and the bolster 4.Increase soft stressed between screen drum 6 and this 5 parts of rotary screen.
In the accompanying drawings, for example screen drum 6 weight of rotary screen are 2.3t, and the angle between the axle of the bolster 4 and second support wheel 5 is 80 °.The all stressed 1.76t of axle of the bolster 4 and second support wheel 5.It is after two first support wheels support, to regulate all stressed 0.88t of first support wheel (2,3) through sliding bearing that bolster 4 makes two-wheel into.Reduced the rigid stressed effect of single support wheel.Make the axle of second support wheel 5 reduce the stress deformation that rises and falls and caused because of 4 the fixing rotary screen screen drum that is brought 6 motions of tradition.Prolonged the rotary screen whole service life.
The utility model rotary screen has improved traditional four-wheel positioning mode promptly by each two of four support wheels front and back; The location rotary screen screen drum 6, use instead now six take turns the location change the support wheel 5 in left side into supporting seat 1, first support wheel (2,3), bolster 4, set square 7; Make cushioning effect reinforcement between screen drum and the support wheel; Increase support wheel service life, reduce noise pollution and resonant frequency, reduced the support wheel replacement cycle.Soft stressed between the screen drum 6 of rotary screen and this 5 parts prevents the rigid vibrations between single in the past support wheel and the screen drum, thereby causes the screen drum life-span to be reduced.Reduced the rigid stressed life-span reduction that causes equipment of the long-term wheel of single support equally.
The utility model rotary screen has increased the service life of screen drum compared with prior art; The replacing frequency that reduces support wheel reaches economical with materials.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from the spirit and the scope of the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also is intended to comprise these changes and modification interior.
