The inclined material receiving members 4 facilitate the dispersion of the material, since the material is dispersed around after collision with the material receiving members 4.

As shown in fig. 1 to 5, the material dispersing member 9 is disposed on the receiving surface d of the receiving member 4, for the material falling on the receiving surface d, the moving material is forced to be dispersed along the material dispersing member 9 due to the existence of the material dispersing member 9, so that the material is prevented from falling down on a certain position on the belt conveying mechanism C in a concentrated manner, and the air separation material falls on the belt conveying mechanism C in a dispersed manner, so that dust is removed on one hand, and the material on the belt conveying mechanism C is not in a stacked state on the other hand, thereby improving the uniformity of the transverse distribution of the material and the success rate of air separation.

The working process of the dispersion type feeding hopper A is as follows:

as shown in fig. 1 to 5, the former material enters the feed inlet 3, collides with the receiving part 4 by inertia and gravity, disperses the material during the collision, and the thick portion of the material flow center section formed by the characteristics of the belt conveyor is forcedly dispersed by the receiving surface d of the material dispersing part 9, and after being decelerated, uniformly falls onto the main plate surface e of the skirt 8, collides with the main plate surface e again to obtain dispersion, falls onto the belt conveying mechanism C after passing through the skirt 8, collides with the belt conveying mechanism C for the third time to obtain dispersion, and then enters the next flow.

The second adjusting mechanism comprises a third hole 55 and a second locking part, the third hole 55 is arranged on the outer side wall surface of the swing arm 52, and the third hole 55 is preferably a strip-shaped hole.

As shown in fig. 1, 7 to 9, the first driving assembly includes a first screw rod 56 and a first connecting seat 57 having a threaded hole, the first screw rod 56 is in threaded connection with the threaded hole on the first connecting seat 57, and the second locking member is engaged with the third hole 55 after passing through the first connecting seat 57 and the first assembling hole 32.

As shown in fig. 1, 7 to 9, since one end of the swing arm 52 is hinged to the mounting seat 46, when the first driving assembly drives the other end of the swing arm 52 to rise or fall, the swing arm 52 is caused to perform a rotational movement, so that, on the one hand, the height of the air blast nozzle 51 mounted on the swing arm 52 is changed, and on the other hand, the angle of the air flow output of the air blast nozzle 51 is changed with respect to the distributing roller 47. Through the adjustment, when the distance between the air blowing nozzle 51 and the separation assembly D is adjusted through the first adjusting mechanism to change, the flow direction of the air flow output by the air blowing device E is tangential to the peripheral surface of the separation assembly D through the adjusting action of the second adjusting mechanism and the first driving assembly, so that the air separation efficiency is ensured.

In the present invention, as shown in fig. 1, 10 and 11, the material output from the belt conveyor C collides with the separating unit D by adjusting the position of the belt conveyor C by the first adjusting mechanism F, and in this embodiment, the collision of the material with the separating unit D is the fourth time, and the dispersion can be obtained as well. The first adjusting mechanism F is respectively connected with the shell B and the belt conveying mechanism C, the flow direction of the air flow output by the air blowing device E is tangential to the peripheral surface of the separation assembly D, when the material output from the belt conveying mechanism C collides with the separation assembly D, the light material moves along the circumferential direction of the separation assembly D under the actions of air flow pushing and rotation of the separation assembly D, and the heavy material after collision freely falls under the action of self gravity.

As shown in fig. 1, 10 and 11, the materials fall onto the belt conveying mechanism C after being dispersed by the dispersing type feeding hopper a, and are conveyed to the separating assembly D by the belt conveying mechanism C, and the light and heavy materials are required to be separated at the separating assembly D. In the present invention, after the position of the output end of the belt conveying mechanism C is adjusted by the first adjusting mechanism F, the material output from the belt conveying mechanism C collides with the distributing roller 47 in the separating unit D, and this relationship brings the following advantages:

(1) The distance between the output end of the belt conveying mechanism C and the distributing roller 47 is controlled according to the requirement, after the material collides with the distributing roller 47, the distance between the material and the distributing roller 47 is very close, even some materials are stuck on the surface of the distributing roller 47, the flow direction of the air flow output by the air blowing device E is tangential to the peripheral surface of the separating assembly D, and the light materials move along with the distributing roller 47 under the common acting force of the air flow and the distributing roller 47, so that the collision relationship not only separates the light materials and the heavy materials by the air flow blown by the air blowing nozzle, but also takes away the light materials by the common acting force of the air flow and the distributing roller 47, thereby improving the separating effect. The invention is especially suitable for the winnowing of the construction waste. The invention has the advantages that: the success rate of material winnowing and sorting is improved, and the whole working speed of the production line is ensured. The adaptability to different materials is expanded, and the influence of dust particles on the normal operation of equipment is reduced.

(2) After collision, the potential energy of the heavy material is reduced, so that when the heavy material falls freely downwards, the initial speed of the heavy material is reduced, and the risk of crushing other parts is reduced.

(3) Since the position of the output end of the belt conveyor C is adjustable and the material output from the belt conveyor C collides with the distributing roller 47, it is avoided that the material output from the belt conveyor C falls directly on the blowing nozzle 51 to crush the blowing nozzle 51.

In the present invention, after the first adjusting mechanism F adjusts the belt conveying mechanism C, the position where the material output from the belt conveying mechanism C collides with the separating assembly D is the middle upper part of the separating assembly D, that is, the preferable collision position is located at the middle upper part of the separating roller 47, and after the collision occurs, the light material moves more easily along with the separating roller 47 due to the centrifugal force of the separating roller 47 and the acting force of the air flow, so that the air separation effect is better.

As shown in fig. 1, 10 and 11, when the first driving mechanism 61 is operated, the first driving mechanism 61 drives the belt conveying mechanism C to be lifted or lowered, thereby changing the height of the output end of the belt conveying mechanism C. When the second drive mechanism 62 is operated, the second drive mechanism 62 drives the belt conveyor C to move horizontally (the belt conveyor C is in sliding engagement with the inner frame 31 of the housing B), thereby changing the spacing between the output end of the belt conveyor C and the dispensing roller 47 in the separator assembly D. When the first driving mechanism 61 and the second driving mechanism 62 both have an adjusting action on the belt conveying mechanism C, the height, the horizontal position and the discharge angle of the output end of the belt conveying mechanism C can be changed. Therefore, by the action of the first regulating mechanism F, the collision of the material output from the belt conveying mechanism C with the distributing roller 47 can be ensured, thereby achieving the purpose of improving the air separation efficiency.
