The airflow spraying mechanism 30 is used for spraying airflow to the material on the conveyer belt 11 to change the motion track of the material, and the material receiving mechanism 40 is used for receiving the material sprayed by the airflow. Specifically, the airflow spraying mechanism 30 includes a plurality of receiving elbows 41, each receiving elbow 41 has a horizontally oriented feed inlet 411 and a vertically downward discharge outlet 412, two rows of receiving elbows 41 are correspondingly arranged on two sides of each conveyor belt 11, the two rows of receiving elbows 41 are uniformly arranged at intervals along the conveying direction of the conveyor belt 11, and the size of an interval gap between every two receiving elbows 41 is the same as the width size of the receiving elbow 41, that is, every two receiving elbows 41 are arranged in a mode of spacing one receiving elbow 41; the feeding openings 411 of the two rows of receiving elbows 41 on each conveyor belt 11 have opposite orientations, that is, the two rows of receiving elbows 41 are respectively and transversely oriented, and are arranged in a staggered manner, and are staggered by one receiving elbow 41, so that the spacing gaps of the two rows of receiving elbows 41 are opposite to each other.
In the present invention, one significant feature of the arrangement of the receiving elbow 41 is: the two rows of collecting bends 41, which belong to the two conveyor belts 11 and are located on adjacent sides (inner sides) of the two conveyor belts 11, occupy a gap between each other, so that the two rows of collecting bends 41 are combined into one row, and adjacent collecting bends face opposite to each other, so that the advantage of the arrangement is that: the folding elbow arrangement is more dense, especially in the case of correspondingly more conveyor belts 11, so that the area occupied by the equipment can be saved.
The air jet mechanism 30 includes a plurality of air nozzles 31 having control valves 311 for controlling the supply of air to the air nozzles 31, thereby controlling the air nozzles 31 to jet air to the feed ports 411 of the receiving elbow 41 and stopping jetting air. Each conveyor belt 11 corresponds to a row of air nozzles 31 (only two air nozzles 31 are shown in the drawing, in practice, each air nozzle 31 comprises a plurality of air nozzles corresponding to the material receiving elbows 41 one by one), the air nozzles 31 are positioned between the two rows of materials of each conveyor belt 11, specifically, two cross beams 32 are arranged above the front side and the rear side of the frame 12, positioning strips 33 are arranged between the two cross beams 32, each air nozzle 31 is correspondingly arranged at long holes 312 arranged at intervals on the positioning strips 33, the directions of the adjacent two air nozzles 31 are opposite for jetting air flow to the two rows of materials, each air nozzle 31 corresponds to a feed opening 411 of the material receiving elbows 41, and each air nozzle 31 is responsible for jetting air flow to the materials endowed with corresponding characteristic values. Thus, when a material to which a certain characteristic value is given passes through the corresponding air nozzle 31, the air nozzle 31 jets an air flow toward the material so that the material moves laterally, and the laterally moved material enters the material receiving elbow 41 through the material inlet 411 and is then guided out from the material outlet 412.
It should be noted that: each airflow spraying mechanism 30 corresponds to each receiving mechanism 40 for multi-stage screening of materials, and each conveyor belt 11 corresponds to one airflow spraying mechanism 30 and one receiving mechanism 40; the two conveying belts 11 are respectively corresponding to the airflow spraying mechanism 30 and the material receiving mechanism 40, so that the materials are synchronously subjected to multistage screening, and the screening efficiency is improved.
In the collection bends 41 where the adjacent sides of the two conveyor belts 11 merge into a row, the adjacent two collection bends 41 facing opposite are responsible for collecting the material given the same characteristic value, i.e. for collecting the material from the same level on the two conveyor belts 11. As such, every two oppositely facing collection bends 41 in a collection bend 41 that merges into a row are responsible for collecting the same level of material.
The guide mechanism 50 includes a plurality of partition guide members 51 arranged at intervals in the conveying direction of the conveyor belt 11, each partition guide member 51 having a top portion of a sharp point, two guide slopes 511 symmetrically; the material flowing out from the outlet 412 of the receiving elbow 41 is guided out separately by the partition guide member 51. Specifically, the partition guide member 51 is formed by bending a plate-like body. In the present invention, each partition guide member 51 is positioned between each adjacent oppositely facing two of the collection elbows 41 on the adjacent sides of the conveyor belt 11. In this way, the same level of material collected by the two opposite receiving elbows 41 is collected and directed away by the dividing guide 51.
