[0022] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0023] Example 1: A fruit screening machine for sorting navel oranges, such as Figure 1-7 As shown, it includes a support frame 1, a workbench 2, a feed port 3, a partition 4, an inclined plate 41, a rotating plate 42, a detector 5, a cylinder 51, a supporting rod 52 and a lower hopper 53. The upper part of the support frame 1 is fixedly connected to the workbench 2. A working cavity is provided inside the workbench 2. Two partitions 4 for installing detection components and material transfer components are provided in the working cavity inside the workbench 2. Inclined plates 4 for transferring materials are provided on the partitions 4. The two inclined plates 41 are symmetrically arranged and V-shaped. The two inclined plates 41 are horizontally lower on the left and higher on the right as a whole. A material transfer station is separated from the workbench 2 by the partition 4 and the inclined plate 41. A feed port 3 is provided on the right side of the workbench 2. The feed port 3 is connected to the material transfer station. When the navel orange is fed from the feed port When the navel oranges are transferred to the material transfer station in the workbench 2, they roll to the right on the inclined plate 41. During the rolling process, they are scanned and inspected by the detector 5 installed on the right side of the partition 4. The detector 5 is a near-infrared detector with its detection head facing the material transfer station. When the navel oranges pass through the detection area of ​​the detector 5, the infrared rays of the detector 5 penetrate into the interior of the navel oranges. The transmittance spectrum of the navel oranges to the near-infrared light is measured by the transmittance of the near-infrared light, and non-destructive testing is performed to obtain information on the structure and composition of the fruit. This allows the sugar content and the presence of defects in the flesh to be determined. Based on the test information, further testing of the external quality conditions of the fruit is carried out to determine the quality of the selected fruit and to perform more accurate grading.

[0024] Among them, Figure 4-6As shown, no less than three rotating plates 42 are rotatably provided on the inclined plate 41 on the front side, and no less than three cylinders 51 are provided on the partition plate 4 on the front side. The movable rods of the cylinders 51 are fixedly connected with supporting rods 52 supporting the rotating plates 42. The cylinders 51 are respectively located in the same line with the adjacent rotating plates 42, and the supporting rods 52 on the cylinders 51 will slide in contact with the bottom of the rotating plates 42 on the same line. When the detection is in progress, the extension and retraction of the movable rods of the cylinders 51 will make the rotating plates 42 move, and perform the action of screening and unloading. The corresponding cylinders 51 receive the information fed back by the detector 5. When the signal is received and the navel oranges roll onto the corresponding turn plate 42, the movable rod of the cylinder 51 retracts, driving the supporting rod 52 to retract. The turn plate 42 rotates downward in an unsupported state, forming a drop opening on the inclined plate 41. The navel oranges on the turn plate 42 will fall downward. The lower part of the front partition 4 is fixedly connected with a lower hopper 53 corresponding to the number of turn plates 42, and the lower hoppers 53 are respectively installed directly below the corresponding turn plate 42. When the navel oranges fall, they will fall into the corresponding lower hopper 53. Through multiple lower hoppers 53, navel oranges of different qualities are received to achieve graded screening.

[0025] Example 2: Based on Example 1, Figure 3 、 Figure 4 、 Figure 5 As shown, a conveyor member 6 and a shifting block 61 are also included. A conveyor member 6 for shifting the navel oranges to the right is installed on the upper part of the workbench 2. The conveyor member 6 consists of a conveyor belt and two rotating wheels, and is connected to a driving component to work. A number of shifting blocks 61 for shifting the navel oranges are arranged at intervals on the conveyor belt of the conveyor member 6. When the navel oranges fall onto the inclined plate 41 from the feed inlet 3, the conveyor member 6 is started to shift the navel oranges to the right to prevent some navel oranges with special shapes from staying on the inclined plate 41 and causing material jams. At the same time, by adjusting and controlling the working speed of the conveyor member 6, the material transfer and detection are adjusted to the optimal beat point during detection, so that the navel oranges that continuously enter the material transfer station from the feed inlet 3 can be orderly transferred to the right for detection and screening, thereby improving detection efficiency.

[0026] In a specific embodiment: Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, it also includes a detector 2 7. The right side of the partition 4 is equipped with a detector 2 7 for checking the appearance of the navel oranges, and the two detectors 2 7 are symmetrically arranged. The right side of the workbench 2 is provided with a discharge port for discharging defective products. When the navel oranges fall into the feeding station, the detector 2 7 will first perform an appearance inspection on the navel oranges, and then the detector 1 5 will perform an internal inspection. When navel oranges with surface or internal defects are detected, the cylinder 51 of the screening mechanism will not be activated, and there is no need to install a power component for removing defective fruits. The defective fruits are discharged to the outside under the drive of the conveyor 6, which can effectively screen and select the fruits while reducing equipment costs.

[0027] In a specific embodiment: Figure 3 and Figure 7 As shown, a lamp 8 is also included. A lamp 8 for providing lighting is installed on the inner side of the rear partition 4. The light emitted by the lamp 8 will be directed toward the inclined plate 41. When the inspection is in progress, the light provided by the lamp 8 will increase the working brightness at the inspection station, so that the inspection instrument can correctly capture objects and analysis results under the illumination of light, and more clearly display the appearance characteristics and defects of the product, effectively detect product quality, and ensure that the product meets the standards.

[0028] In a specific embodiment, as shown in FIG2 , a soft brush 9 is further included. At least two soft brushes 9 are symmetrically provided on the front and rear sides of the feed port 3 to clean the surface of the fed navel oranges. When feeding, the navel oranges are in contact with the soft brushes 9 to clean the impurities adhering to the surface of the navel oranges to a certain extent. This improves the overall appearance quality of the navel oranges while reducing the impact of impurities on the surface of the navel oranges on the accuracy of detection, thereby improving the accuracy of detection.

[0029] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
