An intelligentized bred locust suction trapper comprises a suction trapping mechanism, a separation box, an isolation mechanism, a collection box and a centrifugal fan communicated with the separation box. The intelligentized bred locust suction trapper is characterized in that a suction head assembly is composed of a central suction head and a plurality of side suction heads arranged in a circumferential direction; an elbow is arranged between a feeding hose and the separation box; the isolation mechanism comprises a tubular isolation box shell, an isolation box rotating shaft arranged on the axis of the tubular isolation box shell, an isolation fan connected with the rotating shaft, and blades extending in the axial direction of the tubular isolation box shell, distributed in a cross mode and fixedly arranged on the isolation box rotating shaft, and the outer edges of the blades are just in contact with the inner wall of the isolation box shell. The bottom of the collection box is provided with a screening mechanism, the screening mechanism comprises a screen with meshes smaller than the body length of locusts, a fixed rotating shaft arranged in the middle of the screen and a movable rotating shaft hinged at one end of the screen, and the movable rotating shaft is connected with an output shaft of a screening motor through a driven connecting rod and a driving connecting rod which are sequentially hinged. The intelligentized bred locust suction trapper solves the problems of low trapping efficiency and poor stability of existing locust trappers.

The invention relates to a suction chamber (5a) for a water beam (1a) for jet impacting on knitted fabric, webs or non-woven fabrics (2) composed of staple fibers, endless filaments or cellulose fibers, either composed of a plurality of layers or mixture thereof. Furthermore the invention also relates to a porous suction surfaces (3a, 3b) used for sucking jetted water (4) and disposed on a lower side (5b) of the suction chamber (5a). The invention achieves the purpose that a water jet released from the water beam is not affected by the jetted water and water fog formed by the jetting in all of the longitudinal direction and / or the latitudinal direction of the water beam in the water jet travel direction, and the conventional general production of water drop under the water beam is prevented. The purpose is realized by such that the suction surfaces (3a, 3b) are disposed in an obliquely extended form, and extended from an upper region (6b) close to the water beam (1a) and / or a liquid-dripping corner (6a) to a lower region (6c) of the suction chamber (5a).
