Description
Technical field
It the utility model is related to grain processing equipment field, specially a kind of equipment electric motor protecting dress on induced-draught fan
Put.
Background technology
In general, the grain in cereal enterprises, generally all can be because of by Around the house, road side before by purchase
On, in the various environment such as field dried and be mingled with such as straw, dust, the various impurity such as gravelstone grain.Thus
Need before procedure by the cylindrical pre-cleaning screen in workshop, vibrating cleaning sieve, vertical air suction road, stone remover, induced-draught fan
Cleared up etc. cleaning equipment.
Wherein, for induced-draught fan, a vibrating motor has been generally included in its structure, its front end gating location is generally all
A refining plate with vibrating motor is provided with, drives refining plate grain to be uniformly laid in refining plate by vibrating motor
On, the blanking in vibration, then the light impurities being contained among grain are siphoned away by the airduct of induced-draught fan upper end.Because on induced-draught fan
Vibrating motor vibrating for a long time, vibrating motor is fixed on refining plate, and vibrating motor be typically by common hard
Stock support supports, and draws suspension by two tiny springs in both sides, this structure can produce under running conditions compared with
Big noise while damping effect is poor, the vibrating motor on refining plate can cause spring materials strain to cause in the case where long-time is vibrated
Spring breakage, and then trigger deformation of timbering to come off, it can also cause refining plate to come off when serious, burn-down of electric motor.
Utility model content
The technical problem that the utility model solves is to provide a kind of equipment electric motor protective device, to solve above-mentioned background
The shortcomings that in technology.
The technical problem that the utility model solves is realized using following technical scheme：
A kind of equipment electric motor protective device, including spring-backed quill and the fixed mount for being connected in spring-backed quill both ends, it is described
Spring-backed quill is composite bushing structure, including outer tube and concentric locking collar the inner sleeve in outer tube, wherein, the overcoat
It is gum sleeve to manage as TPU hollow bushings, the inner sleeve, meanwhile, the inner sleeve form one it is upper and lower respectively with it is solid
Determine the connected spring of frame, and be then the clearance layer that width is 10 ~ 20mm between outer tube and inner sleeve.
In the utility model, the TPU hollow bushings are preferably polyether-type TPU hollow bushings, and casing wall thickness is preferably 6
~8mm。
In the utility model, the assembly building for coordinating the vibrations of refining plate is left between the TPU hollow bushings and fixed mount
Gap.
In the utility model, the casing wall thickness of the gum sleeve is preferably 15 ~ 20mm.
In the utility model, the gum sleeve is each passed through the fixed mount at both ends in upper and lower end face, and is fixed on pair
On the fixed mount answered.
In the utility model, also include the safety lanyard being mounted side by side with spring-backed quill, the safety lanyard is upper and lower
End connects the fixed mount at spring-backed quill both ends respectively.
In the utility model, the fixed mount of spring-backed quill upper end is fastened on the shell of induced-draught fan, and lower end
Fixed mount is then fixed on seven word lever arms of refining plate.
Beneficial effect：The utility model Stability Analysis of Structures, noise is low under continuous duty, vibrating effect is stable, can have
Effect prevented because spring materials strain phenomenon of rupture, and evade due to connector it is unstable caused by the dislocation of refining plate or come off steady
It is fixed, meanwhile, the service life at the position is several times even ten several times of conventional springs connector, can effectively be reduced because of spring breakage
Caused maintenance cost, improves production efficiency.

Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to the preferred embodiment of Fig. 1, Fig. 2 a kind of equipment electric motor protective device, in the present embodiment, the electric motor protecting
Device includes upper holder 1, spring-backed quill 3, safety lanyard 4 and lower fixed frame 6, wherein, spring-backed quill 3 and safety lanyard 4
It is fixed between upper holder 1 and lower fixed frame 6, upper holder 1 is fastened on the shell side of induced-draught fan 2, lower fixation
Frame 6 is fixed on seven word lever arms of refining plate, and is used to drive the vibrating motor 5 of refining plate to be then fixed in lower fixed frame 6.
In the present embodiment, spring-backed quill 3 includes TPU hollow bushings 301, gum sleeve 303 and spring 304, wherein,
Gum sleeve 303 and the concentric locking collar of spring 304 are mounted in TPU hollow bushings 301, and the pipe thickness of gum sleeve 303 is 15mm, its
Upper holder 1 and lower fixed frame 6 are each passed through in upper and lower end face, and is separately fixed at upper holder 1 and lower fixed frame 6
On.And TPU hollow bushings 301 are polyether-type TPU hollow bushings, pipe thickness 6mm, it is also stayed between upper and lower fixed mount
