Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention will be combined to clearly and completely describe the technical solutions of the embodiments of the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art. The terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

Furthermore, the terms "horizontal", "vertical", "overhang" and the like do not imply that the components are required to be absolutely horizontal or overhang, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

Example (b):

referring to fig. 1, the present embodiment provides a material winnowing device 100 and a material winnowing system 010, the material winnowing system 010 includes the winnowing device 100 and a conveying device 200, the conveying device 200 conveys the material with impurities to the front of the winnowing device 100, the winnowing device 100 carries the material away by wind, and the impurities fall below the conveying device 200.

Referring to fig. 1-3, the material winnowing device 100 includes a support 110, an exhaust fan 120 and a turntable 130, wherein the support 110 includes a bottom plate 112 and a vertical plate 114, the bottom plate 112 is used for connecting with a foundation, and the vertical plate 114 is vertically connected with the bottom plate 112; the bottom plate 112 and the vertical plate 114 are reinforced by rib plates. The vertical plate 114 is provided with a rectangular connecting hole, the exhaust fan 120 is fixedly connected with the bracket 110, and an air inlet of the exhaust fan is communicated with the connecting hole. The middle part of the rotating disc 130 is rotatably connected with the vertical plate 114 through a rotating shaft arranged horizontally. A plurality of through holes are uniformly distributed on the turntable 130 and used for materials to pass through. When the exhaust fan 120 is operated, the material in front of the rotary disk 130 can be sucked into the exhaust fan 120 and discharged to other devices through the air outlet pipe.

Specifically, the rotating disc 130 is a circular plate, and a plurality of uniformly distributed circular holes are formed in the rotating disc 130. The vertical plate 114 is a semicircular plate, and the rotary table 130 and the vertical plate 114 are concentrically arranged. A relatively small gap (e.g., 1-5mm) is left between the turntable 130 and the vertical plate 114. If the gap is too small, it may cause the rotating disk 130 to rub against the vertical plate 114 during rotation; if the air inlet is too large, the distance between the air inlet of the fan and the turntable 130 is too large, and the suction force may be insufficient.

In addition, the vertical plate 114 is semicircular, and the straight edge of the vertical plate 114 is vertically arranged; so that only the left side of the turntable 130 (with reference to the intake of the backrest draft fan 120) is shielded by the vertical plate 114.

In this embodiment, the conveying device 200 includes a conveying belt and two side plates, and the two side plates are respectively located at two sides of the conveying belt. The conveyer belt slope sets up, and its lower extreme is the material loading end, and the material loading end is provided with storage hopper 220. The material is placed in the storage hopper 220 and can fall directly onto the conveyor belt.

Further, the conveying device 200 further includes a plurality of material-poking rollers 210, and the material-poking rollers 210 include a roller shaft and a plurality of poking teeth. Both ends of the roll shaft are respectively and rotatably connected with the two side plates, and the shifting teeth are arranged on the circumferential surface of the roll shaft. The end part of the roll shaft is provided with a chain wheel, and the roll shaft is in transmission connection with a motor through the chain wheel and a chain. When the material stirring roller 210 rotates, materials on the conveying belt can be stirred, so that the blocky materials are scattered.
