DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1-9 The utility model provides a technical solution: a screening device for a nut fruit color sorter, comprising a screening housing 102, wherein the screening housing 102 is provided with a plurality of screening channels 103, wherein the screening housing 102 is rotatably connected with two upper and lower rotating shafts 114 that penetrate each of the screening channels 103, wherein each of the screening channels 103 is provided with a conveyor belt 104 rotatably connected with the two rotating shafts 114, wherein the conveyor belt 104 is fixedly connected with a plurality of material blocking strips 116, and wherein the conveyor belt 104 is provided with a plurality of through holes 109, wherein the lower end surface of the screening housing 102 is fixedly connected with a connecting frame 117, wherein the lower end surface of the connecting frame 117 ... A plurality of jets 113 are connected, each of the jets 113 is fixedly connected to a jet tube 115 passing through the connecting frame 117 and located at the lower side of one row of the conveyor belts 104 in the screening channel 103, the jet tube 115 is perpendicular to the through hole 109 and can be coaxially aligned up and down, a bad fruit screening frame 105 is fixedly connected to the left side of the screening housing 102, the bad fruit screening frame 105 is fixedly connected to a first discharge plate 108 for discharging bad fruits, the bad fruit screening frame 105 and the screening housing 102 are fixedly connected to a good fruit screening frame 107, the good fruit screening frame 107 is fixedly connected to a second discharge plate 112 for discharging good fruits.

[0024] The bad fruit screening frame 105 is in communication with the screening channel 103, and the bad fruit screening frame 105 separates good fruits from bad fruits;

[0025] The front end surface of the screening housing 102 is fixedly connected with a motor 106, and the motor 106 is connected to the rotating shaft 114 at the lower side by power;
