Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
An embodiment of a building material screening apparatus of the present invention, as shown in fig. 1-7, includes a housing 100 and a screening shaft assembly 200.
The plurality of screening shaft groups 200 are distributed from high to low in an inclined manner, and the distribution direction of the plurality of screening shaft groups 200 in the horizontal direction is the first direction.
The screening shaft assembly 200 comprises a rotating disc 210, a fixed rod 220, a follower ring 230, a movable rod 240 and a limiting ring 250, wherein at least two rotating discs 210 are rotatably installed in the housing 100 around a second direction perpendicular to the first direction, and the at least two rotating discs 210 are distributed at intervals along the second direction; wherein the second direction is a horizontal direction. The fixed rods 220 and the movable rods 240 are multiple and are sequentially and alternately distributed uniformly around the circumference of the rotating disc 210 and are all arranged along the second direction; the follower ring 230 is coaxial with the rotating disk 210 and fixedly connected to both the rotating disk 210 and the stationary rod 220. The outer circumferential surface of the follower ring 230 is provided with a plurality of arc grooves 231 uniformly distributed around the circumference of the follower ring 230, and the moving rod 240 passes through the arc grooves 231 and can rock in the arc grooves 231. The limiting ring 250 is sleeved outside the plurality of moving rods 240, the diameter of the limiting ring is larger than that of the follower ring 230, the limiting ring 250 is eccentrically arranged relative to the follower ring 230, and the axis of the limiting ring 250 is located right above the axis of the follower ring 230.
The lower portion of the stop collar 250 coincides with the lower portion of the follower collar 230, and a plurality of protrusions 251 are uniformly distributed on the stop collar 250 around the circumference thereof, preferably, the number of the protrusions 251, the fixed lever 220 and the movable lever 240 are equal. When the fixed rod 220 or the movable rod 240 rotates to the lower part of the follower ring 230, the pushing projection 251 rotates the limiting ring 250, and at least one movable rod 240 rotating to the lower part of the follower ring 230 is abutted against the side wall of the arc groove 231 under the pushing of the projection 251, so that the distance between the movable rod 240 and one adjacent fixed rod 220 is increased, and the materials in the inner space defined by the fixed rods 220 and the movable rods 240 are caused to fall.
Specifically, two rotating discs 210 are disposed at two ends of the fixed rod 220, and two adjacent rotating discs 210 are connected by a belt transmission, wherein one rotating disc 210 rotates under the driving of a motor, so as to drive the rotating disc 210 of the screening shaft group 200 adjacent to the rotating disc 210 to rotate. At least three follower rings 230 are provided, two of which are positioned at both ends of the movable rod 240 and fixedly connected to the rotating disk 210 positioned at the same side thereof, respectively. The fixed rod 220 passes through the follower ring 230 and is fixedly connected with the follower ring 230, the movable rod 240 rotating to the upper part of the follower ring 230 is supported in the arc groove 231 under the action of gravity, and the movable rod 240 rotating to the lower part of the follower ring 230 is not separated from the arc groove 231 under the restriction of the limiting ring 250. In addition, since the stop collar 250 is eccentrically disposed with the follower collar 230, and the axis of the stop collar 250 is located directly above the axis of the follower collar 230, the distance between the upper end of the stop collar 250 and the upper end of the follower collar 230 is maximized, which is smaller than the diameter of the moving rod 240, so as to prevent the moving rod 240 from being separated from the arc groove 231 under the extrusion of the material. The limiting rings 250 are at least two and are spaced apart along the second direction to increase the stability of the support of the movable rod 240. The stopper ring 250 is supported on both sides of the fixed rod 220 of its adjacent sifting shaft group 200 in the first direction so as to always maintain the eccentricity with the follower ring 230.
When the screening shaft groups 200 work, the screening shaft groups 200 rotate in the same direction, and the materials are caused to flow on the screening shaft groups 200 from high to low while rotating, and after passing through the gaps between the fixed rods 220 and the movable rods 240, the materials with qualified sizes fall into the inner space defined by the fixed rods 220 and the movable rods 240, and then fall from the gaps between the fixed rods 220 and the movable rods 240 positioned below or fall from the gaps between the adjacent two screening shaft groups 200. The inner space defined by the fixed rod 220 and the movable rod 240 is a transition space, and the material entering the transition space has been screened once, so that the faster the material can be discharged, the better. By means of the eccentric arrangement of the limiting ring 250 and the follower ring 230, the lower part of the limiting ring 250 is overlapped with the lower part of the follower ring 230, when the fixed rod 220 or the movable rod 240 rotates to the lower part of the limiting ring 250, at least one movable rod 240 is abutted with the convex block 251, and the movable rod 240 is pushed by the convex block 251 to be abutted with the side wall of the arc groove 231 under the relative rotation of the follower ring 230 and the limiting ring 250, so that the distance between the movable rod 240 and one fixed rod 220 adjacent to the movable rod 240 is increased, and the falling of materials in a transition space is accelerated. And when the fixed rod 220 or the movable rod 240 rotates to be in contact with the protruding block 251, the limiting ring 250 is pushed to rotate, so that the protruding block 251 on the limiting ring 250 does not block the rotation of the fixed rod 220 and the movable rod 240.
In this embodiment, the two ends of the fixed rod 220 are respectively provided with a blanking space, and the blanking space is communicated with the lower part of the sieving shaft group 200 and does not participate in sieving materials. Specifically, the follower rings 230 and the rotating discs 210 at two ends of the moving rod 240 are connected by a plurality of connecting rods 211, the plurality of connecting rods 211 are circumferentially spaced around the rotating discs 210, the distance between adjacent connecting rods 211 is larger than the maximum distance between the fixed rod 220 and the moving rod 240, the plurality of connecting rods 211, the rotating discs 210 and the follower rings 230 define a blanking space, and the upper part of the blanking space is shielded by the side wall of the housing 100, so that materials are prevented from falling into the blanking space from the upper part of the blanking space. The spiral blades 260 are disposed in the inner space defined by the plurality of fixed bars 220 and the movable bars 240, and the spiral blades 260 are fixedly connected with the rotating disk 210 or the fixed bars 220 and promote the materials in the inner space defined by the plurality of fixed bars 220 and the movable bars 240 to flow to the discharging space along the two ends of the second direction when rotating along with the rotating disk 210 or the fixed bars 220. That is, the spiral blade 260 includes two blades having opposite rotation directions, and the two blades are sequentially distributed and fixedly connected in the second direction.
In this embodiment, the surface of the bump 251 near the inner ring of the stop collar 250 is a cambered surface.
In this embodiment, a feed inlet 110 is formed on the housing 100, and a guide plate 120 inclined from top to bottom to a side close to the screening shaft group 200 is disposed in the housing 100; a plurality of buffer shaft groups 130 are arranged in the shell 100 and at the lower end of the material guiding plate 120, and the buffer shaft groups 130 and the screening shaft groups 200 are distributed along the same inclined direction and are higher than the screening shaft groups 200. After entering from the feed inlet 110, the material falls to the buffer shaft group 130 along the guide plate 120 to be buffered, and then flows to the sieving shaft group 200 along the inclined direction of the buffer shaft group 130.
In this embodiment, a plurality of separators 300 are disposed on the sieving shaft set 200 at intervals along the second direction, the separators 300 divide the sieving shaft set 200 into a plurality of mutually independent sieving areas along the second direction, and the materials flowing from the buffer shaft set 130 to the sieving shaft set 200 are separated by the separators 300, so as to hinder the materials from gathering and accumulating in the second direction, and affect the sieving efficiency.
In the present embodiment, the follower ring 230 and the limiting ring 250 are staggered in the second direction, so as to avoid the limiting ring 250 from affecting the discharge of the material falling into the arc groove 231 of the follower ring 230.
In this embodiment, the limiting ring 250 is an annular structure formed by a plurality of arc segments, and two adjacent arc segments are detachable, so as to facilitate the installation of the limiting ring 250.
In this embodiment, the cross section of the arc groove 231 perpendicular to the second direction is in a U shape with an opening facing the outer peripheral surface of the limiting ring 250, and the width of the arc groove 231 of the U shape in the circumferential direction and the width of the arc groove 231 in the radial direction of the limiting ring 250 are both larger than the diameter of the movable rod 240, so that the movable rod 240 can shake in the arc groove 231.
In this embodiment, a receiving bin 140 is further disposed in the housing 100, and the receiving bin 140 is located on a side of the sieving shaft set 200 away from the buffer shaft set 130, for receiving the material that does not pass through the sieving shaft set 200.
In this embodiment, a discharge port 150 is formed in the bottom of the housing 100 and is in communication with the underside of the sieving shaft assembly 200, so as to facilitate the discharge of the qualified materials passing through the sieving shaft assembly 200.
When the material screening device for building construction is used, the rotating discs 210 of the screening shaft groups 200 are driven by the external motor to rotate in the same direction. After entering from the feed inlet 110, the material falls to the buffer shaft group 130 along the guide plate 120 to be buffered, and then flows to the sieving shaft group 200 along the inclined direction of the buffer shaft group 130. The fixed rod 220 and the movable rod 240 of the sieving shaft group 200 rotate while promoting the material to flow on each sieving shaft group 200 from high to low, and after passing through the gap between the fixed rod 220 and the movable rod 240, the qualified size material falls into the inner space defined by the fixed rod 220 and the movable rod 240, and then falls from the gap between the fixed rod 220 and the movable rod 240 located below, or falls from the gap between the adjacent two sieving shaft groups 200. The material entering the inner space defined by the plurality of fixed bars 220 and the movable bars 240 is pushed by the spiral blades 260 to flow from the middle part of the screening shaft group 200 to both ends, and then discharged from the discharging spaces at both ends of the fixed bars 220. The materials which do not pass through the sieving shaft group 200 flow on each sieving shaft group 200 in sequence, finally fall to the material receiving bin 140, and the materials which pass through the sieving shaft group 200 fall below the sieving shaft group 200 and can be discharged from the material outlet 150.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
