Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0025] like Figure 1-Figure 6As shown, a feed processing sorting screen with multi-stage screening includes a sorting screen mechanism 1, which includes a placing frame 101, and a support frame 102 is fixed to the upper side of the placing frame 101 near both ends. Two L-shaped frames 103 are fixed to both sides of the inner wall of the placing frame 101, and a perforated circular ring block 108 is fixed between the tops of the four L-shaped frames 103, and the discharge port of the perforated circular ring block 108 faces downward. A round rod 104 is rotatably connected between the two supporting frames 102 through a bearing, and the perforated circular ring block 108 is fixed to the inner side of the two supporting frames 102. 8 is provided with a first sorting screen 105 inside, a second sorting screen 106 is provided inside a perforated circular ring block 108, flat plates 107 are fixed on both sides of the first sorting screen 105, a motor 109 is installed on one side of one of the support frames 102, a receiving box 110 is fixed on the upper side of the placement frame 101 near the other support frame 102, a circular block 111 is fixed on the side of the first sorting screen 105 away from the motor 109, one end of the round rod 104 is installed with the output end of the motor 109, and the round rod 104 The two ends are respectively fixed through the opposite sides of the two flat plates 107, and the opposite sides of the two flat plates 107 are respectively fixed to the two sides of the second sorting screen 106, one of the flat plates 107 is located between the two grooves of the annular block 111, and the end of the annular block 111 close to the other support frame 102 is directly above one of the receiving ports of the receiving box 110, and the end of the second sorting screen 106 away from the motor 109 is directly above the other receiving port of the receiving box 110, and the second sorting screen 106 is located inside the first sorting screen 105 and the perforated circular ring block 108, and the first flow guide shell 2 is fixed to the bottom of the receiving box 110, and the second flow guide shell 3 is fixed to the bottom of the receiving box 110, and sealing rings 4 are fixed on both sides of the perforated circular ring block 108, the interior of the first flow guide shell 2 is connected to the interior of the other receiving port of the receiving box 110, and the interior of the second flow guide shell 3 is connected to the interior of one of the receiving ports of the receiving box 110, and the opposite sides of the two sealing rings 4 are respectively in contact with the two sides of the second sorting screen 106.
[0026] The effect achieved is that when it is necessary to perform multi-stage sorting of the feed, the motor 109 is first connected to the external controller (PLC controller), and then the controller is connected to the external power supply. Then, the feed to be sorted is placed from one end of the first sorting screen 105 into the interior of the first sorting screen 105, and then the motor 109 is started by the controller. At this time, the started motor 109 will drive the round rod 104 to rotate with the cooperation of the two support frames 102, the placement frame 101 and the bearing, and the rotating round rod 104 will directly drive the first sorting screen 105 and the second sorting screen 106 to rotate together with the cooperation of the two flat plates 107. When the first sorting screen 105 and the second sorting screen 106 rotate together, the feed placed inside the first sorting screen 105 can be screened under the action of the rotating first sorting screen 105. At this time, the oversized feed particles will remain in the interior of the first sorting screen 105 and then be diverted to the inside of the annular block 111. The feed particles that meet the requirements and are too small will directly fall into the second sorting screen 106. When the feed particles that meet the requirements and are too small enter the second sorting screen 106, the second sorting screen 106 will be rotated to perform the screening operation again. At this time, the feed particles that meet the requirements will remain in the second sorting screen 106, and then be guided to another receiving port of the receiving box 110, and then be guided to the first guide shell 2, and then be guided away. The feed particles that are too small will directly fall into the inside of the perforated circular block 108, and then be guided out from the through hole of the perforated circular block 108. When the feed inside the first sorting screen 105, the second sorting screen 106 and the perforated circular block 108 are all guided away, the motor 109 is turned off by the controller, and the feed can be sorted in multiple stages.
[0027] Working principle: When it is necessary to perform multi-stage sorting of the feed, the motor 109 is first connected to the external controller (PLC controller), and then the controller is connected to the external power supply. Then, the feed to be sorted is placed from one end of the first sorting screen 105 into the interior of the first sorting screen 105, and then the motor 109 is started by the controller. At this time, the started motor 109 will drive the round rod 104 to rotate with the cooperation of the two support frames 102, the placement frame 101 and the bearing, and the rotating round rod 104 will directly drive the first sorting screen 105 and the second sorting screen 106 to rotate together with the cooperation of the two flat plates 107. When the first sorting screen 105 and the second sorting screen 106 rotate together, the feed placed inside the first sorting screen 105 can be screened under the action of the rotating first sorting screen 105. At this time, the oversized feed particles will remain in the interior of the first sorting screen 105 and then be diverted to the interior of the annular block 111 , and then be directed to one of the receiving ports of the receiving box 110, and then be directed to the interior of the second flow guide shell 3, and then be directed away, while the feed particles that meet the requirements and are too small will directly fall into the interior of the second sorting screen 106. When the feed particles that meet the requirements and are too small enter the interior of the second sorting screen 106, the second sorting screen 106 will be rotated at this time. The screening operation will be performed again. At this time, the feed particles that meet the requirements will remain in the interior of the second sorting screen 106, and then be directed to another receiving port of the receiving box 110, and then be directed to the interior of the first flow guide shell 2, and then be directed away, while the feed particles that are too small will directly fall into the interior of the perforated circular ring block 108, and then be directed out from the through hole of the perforated circular ring block 108. When the feed inside the first sorting screen 105, the second sorting screen 106 and the perforated circular ring block 108 are all directed away, the controller is used to turn off the motor 109, and the feed can be sorted in multiple stages.
[0028] The diameter of the screening opening of the first screening screen 105 is larger than the diameter of the screening opening of the second screening screen 106 .
[0029] The motor 109 in the present invention belongs to the prior art, and its working principle is a well-known technology. The model is selected according to the actual use, so the motor 109 will not be explained in detail.
