The decline in grain storage quality is a malignant change that occurs during the grain storage process, making it unsuitable for processing into finished grains for human consumption. Due to its industry nature and concealment, grain storage quality is not easily perceived by consumers and processors. Grain with severely unsuitable or even mildly unsuitable storage quality can accumulate through the food chain and endanger human health. Therefore, its detection is particularly important.

[0003] There are also some grain analysis devices in the existing technology, but the degree of automation is not enough, and it is impossible to automatically load and unload materials. In addition, it is impossible to process grain that fails the detection, and manual intervention is required, which is troublesome and affects work efficiency.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

DETAILED DESCRIPTION

[0035] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0036] like Figure 1-Figure 5The utility model provides a device for analyzing imperfect grains in grains, comprising a shell 1, a mounting plate 10 is horizontally arranged at an upper position inside the shell 1, a rotatable glass turntable 2 is arranged at the upper end of the mounting plate 10, an annular groove is arranged at a circumferential position on the upper surface of the glass turntable 2, an automatic feeding device 6 is arranged on one side of the glass turntable 2, and the automatic feeding device 6 outputs grains into the annular groove and rotates with the glass turntable 2.

[0037] An inspection area and a material distribution area are respectively provided in the rotation direction of the glass turntable 2, and an upper camera 3 and a lower camera 4 are respectively provided on the upper surface and the lower surface of the glass turntable 2 in the inspection area. The upper camera 3 and the lower camera 4 take pictures of the grains, and the upper camera 3 and the lower camera 4 transmit the pictures to the processing system, and the processing system analyzes the pictures to distinguish the grains according to moldy grains, damp grains, sprouted grains, worm-eaten grains, frostbitten grains, swollen grains, diseased grains, etc.

[0038] A plurality of feeding channels 8 are provided in the material distribution area, each of which corresponds to a different type of imperfect grain food. An air flow nozzle 9 is fixed at the inlet of the upper end of each feeding channel 8. When the imperfect grain food rotates to the inlet of the corresponding feeding channel 8, the processing system controls the air flow nozzle 9 through the solenoid valve to spray compressed air to blow the food into the feeding channel 8.

[0039] The outlet at the lower end of each feeding channel 8 is provided with a storage barrel 11, and a weighing instrument 12 is fixed on the back side of the storage barrel 11. The weighing instrument 12 weighs the grain in the storage barrel 11, and the weighing instrument 12 transmits the weight of the grain to the processing system. The processing system calculates the percentage of different types of imperfect grains according to the weight of different types of grains, thereby performing imperfect grain analysis on the grains.

[0040] After weighing, the processing system controls the valve at the bottom of the storage barrel 11 to open, so that the grain flows to the discharge drawer 13 at the lower end thereof.

[0041] The automatic feeding device 6 includes a feeding hopper 601, which is in the shape of a funnel with an opening at the upper end and a downward contraction. A feeder 603 is provided at the lower end of the feeding hopper 601. The feeder 603 includes a seeding wheel 611, which is driven by a motor. A plurality of storage pits 612 are provided on the circumferential side wall of the seeding wheel 611. The circumferential side wall of the seeding wheel 611 faces the discharge port at the lower end of the feeding hopper 601. The grain in the feeding hopper 601 falls into the storage pit 612 of the seeding wheel 611. The storage pit 612 rotates with the seeding wheel 611. When the storage pit 612 rotates from the upper end to the lower end, the grain falls to realize the feeding of the grain. The automatic feeding device 6 can realize automatic feeding of grain and automatically complete detection, and the degree of automation is higher.

[0042] A straight vibrating trough 606 is provided at the lower end of the feeder 603, and the straight vibrating trough 606 includes two baffle plates set at an angle, and the bottoms of the two baffle plates intersect in a straight line. The grain is discharged outward along the bottom of the straight vibrating trough 606, and the grain moves along the straight line at the bottom of the baffle plate to prevent grain stacking and achieve the outward flow of grains side by side.

[0043] The grains flow out side by side and fall onto the glass turntable 2 . Since the glass turntable 2 is rotating all the time, there is a time difference between the front and back grains falling, so the grains are arranged at intervals on the glass turntable 2 .

[0044] The discharge port of the straight vibration trough 606 is open, and the rear end is blocked, so that the grain can only flow toward the discharge end.

[0045] The straight vibrating trough 606 is tilted so that the outlet end of the straight vibrating trough 606 is lower than the inlet end, which facilitates the flow of grain to the outlet end.

[0046] A straight vibrator 607 is fixed to the lower end of the straight vibrating trough 606, and the straight vibrator 607 drives the straight vibrating trough 606 to vibrate, so that the grains falling into the straight vibrating trough 606 flow side by side along the bottom straight line toward the outlet.

[0047] A trough connecting block 604 is fixed to the upper end of the straight vibrator 607 , a trough fixing plate 605 is fixed to one side of the trough connecting block 604 , and one of the baffle plates of the straight vibrating trough 606 is fixed to one side of the trough fixing plate 605 .

[0048] The side of the material trough connecting plate 605 is vertically arranged, so that one of the baffle plates of the straight vibration material trough 606 is vertically arranged, and the other baffle plate is inclined. The grain falling from the feeder 603 falls onto the inclined baffle plate, and then the grain slides to the bottom of the straight vibration material trough 606, thus preventing grain accumulation or material breakage.

[0049] A straight vibrator fixing plate 608 is fixed to the lower end of the straight vibrator 607, and height adjustment plates 609 are provided at both ends of the straight vibrator fixing plate 608. The position of the straight vibrator fixing plate 608 on the height adjustment plate 609 is adjustable, so that the discharge height can be adjusted.

[0050] A mounting base plate 610 is provided at the lower end of the height adjustment plate 609 to support the automatic feeding device 6 .

[0051] A feed baffle 602 is provided at the inlet of the feed hopper 601 , and a feed port 101 is provided on the shell 1 , and grain is injected from the feed port 101 and flows into the feed hopper 601 .

[0052] A grain recovery device 7 is provided at the rear side of the material distribution area in the rotation direction of the glass turntable 2, and the grain recovery device includes a grain conveyor 701. The grain conveyor 701 is inclined, and the upper outlet of the grain conveyor 701 is located above the feed hopper 601. The lower outlet of the grain conveyor 701 is provided with a recovery cover 702. The inlet at the upper end of the recovery cover 702 is close to the edge of the glass turntable 2. An air flow nozzle 9 is fixed on the recovery cover 702. When the grain that fails to be distributed due to reasons such as grain coagulation is transferred to the recovery cover 702, the air flow nozzle 9 blows the grain into the recovery cover 702 and delivers it to the automatic feeding device 6 again via the conveyor.
