Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Refer in Fig. 1~2, the embodiment of the present invention, a kind of steel ball classified screening device, including：Elevating hopper 1, distribution cavity 2
And screening frame 5, the elevating hopper 1 is located at directly over distribution cavity 2, and the top of distribution cavity 2 sets feeding port 21, feeding port 21 with it is upper
Hopper 1 is connected；Distribution cavity 2 is in cylindrical, and setting distributing device in it, the distributing device includes：Pivoted frame 10, baffle plate 3 and flight
4, the pivoted frame 10 is fixedly welded in the rotating shaft of the shaft core position of distribution cavity 2, and rotating shaft is driven by drive device, the baffle plate
3 are fixed on the end of pivoted frame 10, and baffle plate 3 is approached in sector, the radius of fan-shaped radius and distribution cavity 2, and the width of baffle plate 3 with
The width sizableness of feeding port 21, the flight 4 is separately positioned on the both sides of baffle plate 3, and the end face of flight 4 and distribution cavity 2 hangs down
Directly, distributing device has four groups, and uniform along the circumferencial direction of rotating shaft respectively；The lower-left of distribution cavity 2 and bottom-right location are respectively provided with one
Bar is along its axial screening tank 22, and the height of screening tank 22 is identical with the maximum gauge of standard steel ball (i.e. with the tolerance of steel ball most
Big dimension limit is equal), when flight 4 is rotated, the steel ball in it is taken up repeatedly in distribution cavity 2, is passing through screening tank 22
When, the steel ball that diameter is less than maximum limit of size can be rolled out from screening tank 22, and diameter is more than the notch size of screening tank 22
Unqualified steel ball then stay in distribution cavity 2, realize the first screening of steel ball, in addition, when baffle plate 3 is rotated, baffle plate 3 can between
Disconnected formula feeding port 21 is blocked, so that being fallen into from elevating hopper 1 in distribution cavity 2 for steel ball discontinuity, carries out interruption feed supplement；
The screening frame 5 is inclined at the both sides of screening tank 22 respectively, and the upper surface of screening frame 5 is by changeover portion 51, the and of section of gathering materials 52
Screening stage 53 is constituted, and the changeover portion 51 is used for steel ball transition, is made the reduction of its movement velocity, is led between changeover portion 51 and screening stage 53
Cross section 52 of gathering materials to connect, the section 52 of gathering materials is in bucket-shaped, and the screening stage 53 is between forming between two relative dividing plates 9
Gap, the width of screening stage 53 is equal with the steel ball minimum limit of size, after steel ball rolls into screening stage 53, in standard of tolerance band
Normal diameter steel ball can not be by gap, then the top from dividing plate 9 is tumbled, and diameter is less than the unqualified of the minimum limit of size
Steel ball then directly drops out of gap, so as to realize the postsearch screening to steel ball, obtains the qualified steel ball in standard size range.
The bottom of the distribution cavity 2 set with the big discharging opening 7 of the grade of feeding port 21, after screening terminates, for by cloth
Large scale steel ball takes out in chamber 2.
