Description

Technical Field

[0001] The utility model relates to the technical field of grain detection, in particular to a device for detecting and removing defective soybean grains. Background Technique

[0002] Soybeans are important raw materials for making various soy products, extracting soybean oil, brewing soy sauce, and extracting protein. Moreover, the soybean dregs or coarsely ground soybeans produced during the specific production process are also commonly used in livestock and poultry feed, with wide uses and high nutritional value.

[0003] With the increasing demand and the continuous development of related technologies, the related equipment for soybean production is also developing towards automation and production line. For example, the patent document with the application number 202020265170.3 proposes that "a detector is used to detect the characteristics of soybeans. When defective soybean grains appear, an air gun is used to blow the defective soybean grains, so that the defective soybean grains deviate from the original falling line and fall into the waste storage room; the brightness of the inner cavity of the feeding hopper can be improved through the setting of supplementary light lamps, which is convenient for the detector to accurately detect soybeans; an external motor drives a gear to rotate through a rotating shaft, and the tooth pieces on the side of the gear act on the stoppers in sequence. With the cooperation of elastic bodies, the stoppers drive the movable plate to vibrate inside the notch, thereby driving the soybeans gathered at the discharge port to vibrate, avoiding the blockage phenomenon of soybeans at the discharge port 9".

[0004] From the above disclosed technical content, it uses the principle of a color sorter to select and remove defective grains during the detection process, achieving the use effect of automatic screening. However, for the problem of blockage at the discharge port, it is dredged by vibration. In theory, it is feasible, but in practice, due to the lack of direct pressure, the dredging effect is average.

[0031] Working principle:

[0032] Example 1

[0033] The bean raw materials flow one by one through the feeding box 1 to the inner space at the top of the screening box 2. During the further flowing process, the first color CCD lens 5 detects the bean grains. If the bean grains are intact, they will vertically fall into the interior of the pre-inspection plate 7 under the action of gravity for temporary storage. And the first brake servo motor 95 inside the meshing support assembly 9 is set to perform reciprocating rotation and reset operation in a certain time period. Then, the arc-shaped tooth plate 94 and the transmission gear 93 are meshed and driven under the support of the positioning rod 92 and the first support sleeve plate 91, so that the pre-inspection plate 7 connected to the arc-shaped tooth plate 94 rotates reciprocally synchronously for guiding materials and resetting.

[0034] If the first color CCD lens 5 detects that the bean grains are moldy or damaged, the electromagnetic nozzle 6 and the existing gas transmission equipment are linked, so that the electromagnetic nozzle 6 blows and pushes the bad bean grains. Subsequently, the bad bean grains enter the interior of the recovery space under the action of the air flow and then enter the first material receiving pipe fitting 13 for buffering.

[0035] When the electromagnetic nozzle 6 fails to successfully remove the bad bean grains and the bad bean grains fall into the interior of the pre-inspection plate 7, the second color CCD lens 8 will link the air-blowing pump 11 after re-inspection, so that the air-blowing pump 11 blows air to the bean grains inside the pre-inspection plate 7 through the air transmission pipe 10, and makes multiple bean grains containing bad bean grains be discharged to the outside through the material guiding pipe 12 for collection.

[0036] Embodiment 2

[0037] The screening and detection of the bean raw materials are operated according to the steps of the above Embodiment 1. When the raw materials at the top of the feeding box 1 are blocked, the stirring rod 163 inside the stirring assembly 16 can be started, so that the stirring rod 163 drives multiple stirring rods 163 to stir the bean raw materials inside the feeding box 1 through the transmission shaft 162, improving the flowing speed of the bean grains and stirring and clearing the blockage of the bottom space of the feeding box 1.
