[0028] The anti-blocking device 2 is composed of a fifth motor 24, a bristle brush roller 25, and a fixed bracket 26. The fifth motor 24 is vertically fixed on the fixed bracket 26. The bristle brush roller 25 is fixed on the shaft of the fifth motor 24. The fixed bracket 26 is fixed on the conveyor belt baffle of the conveying device 3. The bristle brush roller 25 is located at the door-shaped opening on the outer baffle 32 of the material sorting device 1.

[0029] The steering device 5 is composed of a paddle assembly 27, a fixed plate 28, and a sixth motor 29. The paddle assembly 27 is fixed on the shaft of the sixth motor 29, the sixth motor 29 is bolted to the fixed plate 28, and the fixed plate 28 is fixed to the conveyor belt baffle of the conveyor device 3. The sixth motor 29 adopts a servo system composed of a high-precision servo motor and a servo driver, and the steering action is controlled by PLC. After collecting and analyzing the characteristics of corn, when the direction of the corn is the direction of the corn required by the next process, the paddle assembly 27 directly transmits the corn to the steering device; ... When the direction of the corn in the next process is reversed, the paddle assembly 27 can first make a yielding action, and the time of the yielding action can be set through the industrial human-machine interaction interface. After the paddle assembly 27 makes the yielding action, part of the corn enters the buffer plate 18 of the steering device 6 which is tilted upward at a certain angle through the conveying device 3. At this time, the paddle assembly 27 makes a striking action under the drive of the sixth motor 29, and adjusts the corn backward to enter the steering device 6; the buffer plate 18 has a smooth plate surface, which can prevent the corn from overshooting, and can also provide auxiliary effect for accurately striking the corn at the required position.

[0030] The steering device 6 includes a fourth motor 23 obliquely arranged at the bottom layer of the bogie, a power shaft 22 arranged vertically and connected to the gearbox of the fourth motor 23, an upper end of the power shaft 22 fixedly connected to a coupling 21, and the coupling 21 is bolted to a circular plate 20, a conical turntable convex plate 19 is fixedly arranged in the middle of the circular plate 20, a side baffle 17 with a length of about 1 / 2 of the circumference is arranged on the outer side of the circular plate 20, and the side baffle extends outward along the tangent direction of the circular plate 20, and a right-angled buffer plate 18 composed of two pointed plates is arranged at the entry position, and the buffer plate 18 is low near one end of the circular plate 20 and high on the outer side.

[0031] The stopping conveyor 7 and the accelerating feeding conveyor 8 both have the same PVC special-shaped conveyor belt as the conveyor 3. A corn position detection sensor 9 is installed on the discharging side of the stopping conveyor belt. The driving system is a servo system composed of a servo motor and a servo driver. The belt transmission speed is adjustable. When the corn position detection sensor 9 detects that corn has passed, the servo motor will stop and start quickly after stopping for a set time, thereby achieving the effect of quickly separating the corn spacing. After the corn is separated by the stopping conveyor, it enters the accelerating feeding conveyor to further widen the corn spacing, ensuring that the corn can enter the next process in an orderly manner.

[0032] The width of the flange of the upper turntable 35 can only transport one corn cob.

[0033] A triangular stopper 10 is arranged on the inner side of the outer baffle plate 32 of the material sorting device 1 and on the flange of the upper rotating disk 35 for cleaning the upright corn cobs.

[0034] The third conveyor belt 15 on the conveying device 2 is made of PVC material, has a special anti-slip texture on the surface, and is specially treated at high temperature to adhere two guide strips to limit the radial swing of the corn.

[0035] The corn feature detection device adopts a rectangular regional optical fiber counter-radiation sensor and cooperates with an amplifier with special functions to convert the shape feature points of the corn into electrical signals through optical signals, and converts the electrical signals into digital quantities through a control system for data collection and analysis.

[0036] When the bottom turntable 33 rotates, the corn moves to the edge of the turntable under the influence of centrifugal force, and enters the upper turntable 35 from low to high. The upper turntable 35 is arranged horizontally, and the width of the highest point of the upper turntable is adjustable. Normal production can only accommodate one corn. The corn is lifted by the bottom turntable 33, and then transmitted to the anti-blocking device by the upper turntable 35. After being processed by the anti-blocking device, it enters the conveying device 3, and the conveying device 3 is located in the tangential direction of the upper turntable. The linear speed of the conveyor belt 15 of the conveying device 3 is greater than the linear speed of the upper turntable 35, so the spacing of the corns can be pulled apart one by one, and a certain spacing is maintained on the conveying device, and the corns enter the corn feature detection device 4 in an orderly manner for detection one by one. The corn feature detection device 4 is located at the rear end of the conveying device. After the detection, the control system will quickly collect and process data, and use the direction adjustment device 5 to move the materials in different directions to the same direction, and then change the direction of material movement through the steering device 6, and transmit it to the stop conveyor 7. The second conveyor belt 14 cooperates with the corn position detection sensor 9 to process the corns with close spacing, ensuring that there is a certain distance between the corns and stably enters the accelerated feeding conveyor 8 to enter the next production process of the corn.

[0037] In addition, when the corn is transferred from the lower turntable 33 to the upper turntable 35, due to the irregular shape of the corn, when two corn tips are adjacent or the corn tip is adjacent to the stem, horizontal overlap will occur, causing the horizontal direction to be too wide and blocking the feeding port of the conveyor. The rotational force of the bristle brush roller 25 of the anti-blocking device can brush off the overlapping corn and slightly adjust the position of the overlapping part of the corn to ensure that the corn can smoothly enter the conveyor.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
