Specific embodiment:
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described embodiment is only It is a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill Personnel's all other embodiment obtained without making creative work, shall fall within the protection scope of the present invention:
As shown in Figures 1 to 4 is a kind of for the fishing device of waste garrulous material to can be recycled, positioned at external reject chute and transmission belt it Between, including rotary type salvaging mechanism and discharge bucket 1, the rotary type salvaging mechanism include rotating turret, salvaging bucket 2 and driving Mechanism, driving mechanism driving rotating turret rotation, the bucket of salvaging are set as the multiple and circumferentially fixed rotating turret that is mounted on In outer side frame body, in the present embodiment, the bucket of salvaging is set as shape in inverted dustpan shape and with the material of a side opening Bucket structure, it is described salvage bucket salvagings mouth 201 towards unanimously and it is identical as the tangential direction of the turning circumference of rotating turret, thus, When rotating turret rotation, salvaging bucket can be driven to circumferentially rotate in the lateral surface of rotating turret, and since rotating turret is on reject chute, Bucket is thus salvaged when turning to bottommost, the particle in reject chute can be scooped into hopper, be turned to followed by rotating turret Top and the particle in it is discharged to discharge bucket in setting position.
In the present embodiment, the rotating turret includes two annular steel rings 3 being parallel to each other, it is described two annular steel rings it Between be connected and fixed by more fixed links 4, vertical between fixed link and the circle body of annular steel ring to connect, the bottom for salvaging bucket It is fixed on the circle body of two annular steel rings, hopper is in the surface in the gap between two annular steel rings.
In addition, to improve stability when rotating turret rotation, and to improve the stability of strutting system of unitary rotation frame, the drive Motivation structure includes decelerating motor (not shown), support shaft 6, fixing seat 7 and connecting rod 8, and the fixed seating is in outside Annular steel ring the center point, one end of the support shaft passes through fixing seat and fixation and fixing seat can be driven to be freely rotated, real In the application of border, it sets the side of reject chute to the front side of rotating turret, the side of transmission belt is set as the rear side of rotating turret, described It is connected and fixed between fixing seat and the annular steel ring of front side by connecting rod, the both ends of the support shaft pass through lateral bolster support (not shown) is supported and fixed in reject chute (not shown), and in Fig. 1 to Fig. 4, one end of support shaft is not extended Fixing seat sets two groups for lateral support frame and is supported on the both ends of support shaft in practical applications, lateral bolster support it is upper End is equipped with bearing block, and the both ends socket bearing of support shaft is simultaneously mounted on bearing block, and the lower part Ze An of the lateral bolster support Dress is fixed on the groove body edge of reject chute, facilitates installation, support shaft opposite flank support frame is freely rotated, support shaft One end gear 5 is set, the other end gear drive of the shaft end of the decelerating motor and support shaft connects, when concrete application, Decelerating motor can be fixed on lateral bolster support, thus improve integrally-built stability, and facilitate installation.
In the present embodiment, the center point of the annular steel ring in rear side is equipped with bearing sleeve 9, and the bearing sleeve is fixed Side in support shaft and positioned at fixing seat, the support shaft are freely rotated with respect to bearing sleeve, to improve bearing sleeve Stability, the bearing sleeve are connected and fixed by support link 10 and the frame body of lateral bolster support.Two annular steel rings Between be equipped with the striker plate 11 being arranged on the inside of ring steel ring, the gap between the edge of striker plate and the circle body of annular steel ring is less than 1mm avoids particle from leaking out from gap, is connected and fixed between the striker plate and bearing sleeve by they sup-port, into one Step ground, for convenience of discharging, and for convenience of installing, the striker plate is set as two pieces of independent arc panels and is symmetrical arranged, the two Upper and lower side plate body between be respectively formed upper opening 12 and under shed 13, the upper opening is to salvage the discharge gate of bucket, institute Discharge bucket to be stated to be located at below upper opening, striker plate is that opposed annular steel ring is fixed, in specific application, two arc panels Lower end plate body edge between under shed and upper opening be oppositely arranged up and down, the length of the arc panel is greater than annular steel ring The one third of perimeter avoids salvaging bucket when lower part is salvaged, and the material being scooped into is flowed out under shed, thus, in reality In, when salvage bucket after particle is salvaged in lower part, be transported to top overthe openings when, in particle from hopper It pours out and falls in upper opening, and then enter in the discharge bucket below upper opening, and then complete discharging process.
In the present embodiment, for convenience of conveying material, the discharge bucket is obliquely installed, and outlet-inclined impeller vane is down-set and court To external transmission belt, the inside groove of the discharge bucket is set as V-groove, and it is spiral further, in the discharge bucket to be equipped with band The conveying bar 14 of blade, the direction setting of conveying bar Flow of Goods and Materials along discharge bucket, for convenience of the rotation of conveying bar, the conveying bar Both ends be each passed through discharge bucket front-rear side walls and with a deceleration motor (not shown) be rotatablely connected, the deceleration Driving motor is fixed on support rod, and the outlet of discharge bucket is located at the tail end bottom of discharge bucket, thus, when particle imports discharge bucket Upper end entrance when, the rotation of conveying bar is then by spiral paddle belt animal material flow down, until the bottom of discharge bucket tail end Outlet flow out discharge bucket.
In practical applications, the lateral bolster support of the rotating turret is supported and fixed on to the groove body edge of reject chute, and is made It must rotate the top for being placed on reject chute, it, can effectively will be in reject chute when the salvaging bucket turns to the bottommost of rotating turret Waste garrulous material scoops up, and the outlet of the discharge bucket falls into biography from the particle of discharge bucket discharge in the top of the entrance of transmission belt Defeated take is taken away by transmission, thus, when operating normally, start decelerating motor first, support shaft rotation driven by decelerating motor, Support shaft drives the fixing seat and annular steel ring rotation of front side, then drives the rotation of unitary rotation frame, then drives and salvage bucket Waste material in reject chute, is then scooped into bucket by circular-rotation, is then transported at the upper opening at top, internal particle Upper opening is flowed out under the effect of gravity, and flow to the feed inlet of discharge bucket by upper opening, is then transmitted by spiral blade It is driven in discharge bucket under the drive of bar, and finally flows out and taken away on discharge bucket to transmission belt by transmission, so far complete particle Salvage transmission process.
The above-mentioned fishing device for waste garrulous material to can be recycled can not only effectively realize the fast salvaging process of particle, Er Qieneng Effectively the material after salvaging is quickly discharged, and saves installation space, avoids occupying more fabricating yard, improves life Produce utilization of area rate, save the cost.
It is emphasized that: the above is only presently preferred embodiments of the present invention, not make in any form to the present invention Limitation, any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the invention, All of which are still within the scope of the technical scheme of the invention.
