Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.

The utility model provides a building engineering construction raw materials sieving mechanism, includes screening case 1:

be provided with on the 1 roof of screening case and extend to its inside feeder hopper 2, wherein vertically be provided with live-rollers 3 in the screening case 1 under 2 exit ends of feeder hopper, and evenly be provided with broken arch 4 on the 3 lateral walls of live-rollers, still vertically be provided with in the screening case 1 and be located the drive shaft 8 under live-rollers 3, and drive shaft 8 and live-rollers 3 then by the motor drive in the screening case 1 outside.

Wherein detain the V template 9 that the back-off set up on the drive shaft 8, and evenly be provided with the toper arch on the V template 9 top terminal surface, V template 9 both ends and screening case 1 correspond between the inside wall and have the blanking mouth 10, and are located the screening case 1 of V template 9 below and still are provided with V type sieve 11, department is provided with discharging pipe 12 in the middle of V type sieve 11 bottom, and wherein the V type sieve 11 bottom of discharging pipe 12 both sides has set gradually multiunit aggregate bin 13, and aggregate bin 13 below is provided with transfer box 14.

In this embodiment, the aperture of the sieve holes in the sidewall of the V-shaped sieve plate 11 gradually increases from the two ends thereof to the middle of the V-shaped sieve plate 11, wherein the sidewall of the V-shaped sieve plate 11 between the discharge pipe 12 and any set of the hoppers 13 at the two sides thereof is a solid structure. Limiting rods 19 are longitudinally arranged in the screening boxes 1 right below two ends of the V-shaped plate 9, and rubber sleeves are sleeved outside the limiting rods 19.

As shown in fig. 1, a protection plate 16 is longitudinally arranged at the top opening of the feeding hopper 2, wherein a motor is arranged at the top of the protection plate 16, and a rotating shaft of the motor is connected with a crushing blade 17 positioned in the feeding hopper 2.

So when using back in leading-in feeder hopper 2 with gravel and sand, motor drive pivot drives broken blade 17 and rotates, and then carry out preliminary breakage in order to prevent its caking to the raw materials in the feeder hopper 2, the raw materials after the breakage drop in screening case 1 simultaneously, another group of motor drive live-rollers 3 is rotatory 4 fast rotations in order to drive this moment, make broken arch 4 of rotatory in-process can break the raw materials that falls through feeder hopper 2 and make its screening case 1 below raise, thereby reach and further carry out the effect of crushing once more to the raw materials of probably caking.

After the crushed raw materials fall on the top end face of the V-shaped plate 9, the raw materials flow down along the inclined plane of the V-shaped plate and fall on the V-shaped sieve plate 11 through the material falling port 10, at the moment, the motor on the outer side of the screening box 1 drives the driving shaft 8 and drives the V-shaped plate 9 to reciprocate clockwise and anticlockwise, and therefore the purpose of swinging the V-shaped plate 9 is achieved, the raw materials on the top end face of the V-shaped plate are shaken off to prevent the problem that the raw materials are deposited on the top end face of the V-shaped plate 9 for a long time and cannot flow down smoothly, and meanwhile, when the raw materials on the top end face of the V-shaped plate 9 are shaken off, the conical bulge can also achieve the purpose of crushing the raw materials flowing downwards on the top end face of the V-shaped plate 9 under the influence of vibration force again to prevent the raw materials from agglomerating.

In the process, the swing amplitude of the V-shaped plate 9 is influenced by the limiting rod 19, so that the V-shaped plate can be propped against the limiting rod 19 after swinging to a certain amplitude, and the influence on the normal work of other components due to the overlarge swing amplitude is prevented.

Wherein when the raw materials that drop on V type sieve 11 were flowing down along its inclined plane, the raw materials can fall to corresponding collecting hopper 13 in through the different sieve mesh sieve of V type sieve 11 mesopore and flow into transfer case 14 to this realization plays the purpose of screening effect to the raw materials, and bulky granule siltation can be discharged by discharging pipe 12 in V type sieve 11 centre department.

As shown in figure 1, all be provided with arc orifice plate 5 in the screening case 1 of live-rollers 3 both sides, and 5 both ends of arc orifice plate are connected with 1 inside wall of screening case and 2 lateral walls of feeder hopper respectively, wherein construct heat accumulation chamber 6 between arc orifice plate 5 and 1 inside wall of screening case and 2 lateral walls of feeder hopper. And a heating plate 7 positioned in the heat accumulation cavity 6 is arranged on the bottom wall of the feed hopper 2.

The junction between the bottommost end of the arc-shaped pore plate 5 and the inner side wall of the screening box 1 is provided with a return port 18 communicated with the heat storage cavity 6, and an air inlet pipe communicated with the heat storage cavity 6 is arranged on the side wall of the screening box 1.

When carrying out the breakage to the raw materials, the accessible is with hot-blast through the leading-in heat accumulation chamber 6 of air-supply line in order to heat 2 lateral walls of feeder hopper, and heat dehumidification its inside raw materials through 2 lateral walls of feeder hopper, the hot gas flow flows into the screening case 1 of its below through arc orifice 5 simultaneously and carries out reheating in order to play the purpose of dehumidification effect to the raw materials that raise, with this be convenient for follow-up breakage to the raw materials and prevent the work of its caking, wherein the raw materials caking reason is one then for receiving the extrusion caking, two then receive the moisture influence and the caking, so can effectively prevent its caking after dehumidifying it.

It still plays the heating effect through hot plate 7 to feeder hopper 2 lateral wall to this dehumidification drying efficiency of raw materials in promoting feeder hopper 2, and still can heat the hot gas flow in heat accumulation chamber 6, make it can promote its dehumidification drying efficiency to the raw materials in the screening case 1 back of flowing in through 5 apertures of arc orifice plate.

Both sides still all are provided with knocking mechanism 15 about the V template 9 both ends, and wherein knocking mechanism 15 is including knocking piece 151, and knocks piece 151 and correspond terminal fixed connection through spring 152 and V template 9.

When the motor drives the V-shaped plate 9 to swing back and forth through the driving shaft 8, the motor can drive the corresponding knocking mechanism 15 to move, the knocking block 151 in the upper knocking mechanism 15 is in contact with the arc-shaped pore plate 5, the upper spring 152 can play a role in buffering and damping at the moment, the raw material adhered to the bottom end face of the arc-shaped pore plate 5 can be knocked down after the knocking block 151 is knocked on the arc-shaped pore plate 5 to be shaken down, the raw material cannot easily enter the heat storage cavity 6 through the aperture of the arc-shaped pore plate 5 due to the small aperture of the arc-shaped pore plate 5, and if the raw material enters the inside of the arc-shaped pore plate and is influenced by the upper knocking mechanism 15 and is knocked down, the raw material flows down along the arc-shaped surface of the arc-shaped pore plate 5 and flows back to the screening box 1 through the backflow port 18 to be processed again.

After the knocking block 151 in the lower knocking mechanism 15 contacts and knocks the V-shaped sieve plate 11, the vibrating V-shaped sieve plate 11 can make the top end surface of the vibrating V-shaped sieve plate flow down quickly, so as to prevent the problem that the subsequent screening work is affected by the long-term deposition of the raw material on the top surface of the vibrating V-shaped sieve plate.

The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
