DETAILED DESCRIPTION

[0022] In the description of the present application, it should be pointed out that the terms "front", "upper", "lower", "left", "right", "vertical", "horizontal" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore cannot be understood as a limitation on the present application.

[0023] The following will be described in conjunction with the accompanying drawings Figures 1-6 Further illustrate the present application.

[0024] In order to solve the problems in the background art, the present application proposes the following technical scheme: a grading device for corn processing, comprising a first conveyor 1 and a second conveyor 2 arranged below the first conveyor 1, the second conveyor 2 is provided with at least one group, and two groups are provided in the embodiment.

[0025] In the embodiment, a detection cover 3 is fixedly connected outside the first conveyor 1, a detection assembly is arranged outside the detection cover 3, the detection assembly is used for detecting the time of corn passing through the detection cover 3, the detection assembly is an optical fiber sensor 4 fixedly connected outside the detection cover 3, a control box 5 is arranged outside the first conveyor 1, a controller is arranged in the control box 5, the controller is an MCU control assembly, the motor 9 is a servo motor 9, the detection cover 3 is of arc structure, which is convenient for passing corn, and the corn is horizontally placed on the first conveyor 1, the motor 9 and the optical fiber sensor 4 are electrically coupled with the controller, so that the time of passing corn can be detected by the optical fiber sensor 4, the length of the corn can be judged, and the corn can be conveniently graded subsequently.

[0026] In a further design, a tossing assembly is provided outside the first conveyor 1. The tossing assembly is used to move the corn onto the second conveyor 2. The tossing assembly includes a fixed frame 7 fixedly connected to the outside of the first conveyor 1, a motor 9 fixedly connected to the outside of the fixed frame 7, and a tossing plate 8 fixedly connected to the output end of the motor 9. The tossing plate 8 has a triangular structure. The motor 9 drives the tossing plate 8 to rotate, thereby moving the corn onto the second conveyor 2. The first conveyor 1 transports the corn. The detection assembly can detect the time it takes for the corn to pass through the detection cover 3. When the time does not meet the requirements, the motor 9 drives the tossing plate 8 to rotate. The tossing plate 8 can move the corn that does not meet the requirements onto the second conveyor 2, thus completing the grading of the corn.

[0027] In addition, in order to guide the corn, a guide frame 6 is fixedly connected to the outside of the first conveyor 1 at the position corresponding to the second conveyor 2.

[0028] In another design, a rotating shaft 12 is rotatably connected to the outside of the lever plate 8, a rotating plate 11 is fixedly connected to the outside of the rotating shaft 12, a connecting plate 13 is fixedly connected to the outside of the rotating plate 11, a contact post 15 is rotatably connected to one end of the rotating plate 11, a limiting plate 10 is fixedly connected to the outside of the lever plate 8, a spring 14 is connected between the limiting plate 10 and the connecting plate 13, and a toggle element is provided between the limiting plate 10 and the lever plate 8.

[0029] The actuating component is a lever 17, which is made of plastic. The lever 17 has a latch 18 on its outside, which is engaged with the outside of the lever plate 8. The lever 17 is slidably engaged with the bottom of the limiting plate 10. A blocking plate 16 is fixedly connected to the outside of the lever 17. By rotating the rotating plate 11, the rotating plate 11 causes the abutment post 15 to stop abutting the limiting plate 10. Then, by sliding the lever 17 left and right, the lever 17 can be removed.

[0030] As another embodiment, in this embodiment, a distance sensor can also be fixedly connected to the top of the detection cover 3 to detect the diameter of the corn, and the corn can also be graded according to the diameter.

[0031] The usage method of this embodiment is as follows:

[0032] Each ear of corn is placed on the first conveyor 1 for conveying. At the same time, the time it takes for the corn to pass through the detection cover 3 is detected by the fiber optic sensor 4. When the set time is exceeded, the motor 9 drives the dial plate 8 to rotate, and the dial plate 8 drives the dial block 17 to rotate. The dial block 17 moves the corresponding corn to the outside of the second conveyor 2, thereby completing the grading of the corn.

[0033] In addition, if it is necessary to replace the toggle block 17, simply rotate the rotating plate 11 so that the rotating plate 11 causes the abutment post 15 to stop abutting the limit plate 10, and then slide the toggle block 17 left and right to remove and replace it.

[0034] Therefore, in this embodiment, not only can corn be graded, but the shift block 17 can also be replaced conveniently and quickly.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] Although embodiments of the present invention have been shown and described, the scope of the present invention will be defined by the appended claims and their equivalents for those skilled in the art.
