[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0019] Reference Figures 1-3 A corn intelligent extraction and separation device is provided. This corn intelligent extraction and separation device includes a feeding mechanism and a flexible peeling mechanism. The feeding mechanism and the flexible peeling mechanism are existing technologies and will not be described in detail here. It also includes a multi-stage separation mechanism, which is located below the flexible peeling mechanism. Multi-stage separation mechanisms include: The machine frame 1 has a separation channel 2 installed on it. A feed hopper 201 is installed on the top of the separation channel 2 and is connected to the discharge port of the flexible stripping mechanism. Multiple inclined guide plates 202 are installed inside the upper section of the separation channel 2, and a partition plate 203 is installed inside the lower section of the separation channel 2, which divides the separation channel 2 into a corn kernel channel and a corn cob channel. The separation structure includes a vibrating screen 3 installed inside the separation channel 2 and a fan 5 (axial flow fan, power 1.5kW) installed outside the separation channel 2. The vibrating screen 3 is driven by a vibrating motor 4, and there is a maintenance gap between the vibrating screen 3 and the inner wall of the separation channel 2. The PLC control unit 6 is installed on one side of the separation channel 2. The PLC control unit 6 integrates a human-machine interface 601. In application, the combination of vibrating screen 3 and fan 5 realizes the synergistic effect of physical vibration and airflow separation, improving the separation accuracy of corn kernels and corn cobs. Combined with the PLC control unit 6 with integrated human-machine interface 601, the equipment operating parameters can be visualized and controlled to reduce the complexity of operation.
[0020] Reference Figure 1 and Figure 2The top opening of the feed hopper 201 is in the shape of a trumpet, and the diameter of the top inner cavity of the trumpet is larger than the diameter of the bottom inner cavity. In application, the diameter of the feed inlet is enlarged to avoid material accumulation and blockage, and to adapt to the continuous feeding needs of corn of different sizes.
[0021] Reference Figure 2 Multiple guide plates 202 are distributed alternately at equal intervals, and the bottom of the guide plate 202 is inclined at an angle of 30-45° to the inner wall of the separation channel 2. In application, the inclined guide plates 202 form an "S-shaped" material path, which prolongs the separation time and utilizes gravity and inertia to achieve preliminary sorting.
[0022] Reference Figure 2 and Figure 3 The cross-section of the vibrating screen 3 is an inverted isosceles trapezoidal structure, and the inclination angle of the inner wall of the vibrating screen 3 is 45-60°. The bottom of the vibrating screen 3 is provided with screen holes 301 arranged in a rectangular array. The screen holes 301 adopt a gradual aperture design, and the aperture gradually decreases along the material movement direction. In application, the inverted isosceles trapezoidal structure enhances the uniformity of vibration transmission. The vibrating screen 3 with a gradual aperture can filter debris in stages and reduce the breakage rate of corn kernels.
[0023] Reference Figure 1 and Figure 2 Vibration motor 4 is installed on separation channel 2. The output shaft of vibration motor 4 is connected to vibrating screen 3. Vibration motor 4 and fan 5 are symmetrically distributed. Vibration motor 4 and fan 5 can achieve stepless adjustment of 50-200Hz and wind speed adjustment of 3-8m / s through PLC control unit 6. In application, the stepless adjustment function is adapted to corn with different moisture contents. For example, high humidity materials can be prevented from sticking by increasing the wind speed, thus improving the adaptability of the equipment.
[0024] Reference Figure 1 and Figure 2 The human-machine interface 601 includes a touch screen operation panel for real-time display of separation efficiency, equipment operating status and energy consumption data. The touch screen operation panel supports switching between parameter preset mode and adaptive adjustment mode. In application, it supports preset parameters (such as corn variety and target separation rate) and real-time feedback adjustment, which can meet the dual needs of standardized production and flexible processing.
[0025] The working principle of this utility model is as follows (taking dry corn processing as an example): Pre-treatment stage and feeding and peeling: Select "dry corn mode" through the touch screen on the human-machine interface 601. The system automatically sets the vibration frequency to 60Hz and the wind speed to 5m / s. Then, the dry corn cob (moisture content ≤14%) is poured into the feeding mechanism. After the material is squeezed by the flexible peeling mechanism, the corn kernels and cobs are initially separated. Multi-stage separation: Primary separation: The material slides down along the guide plate 202, and some of the broken cores fall due to gravity; Secondary screening: Vibrating motor 4 drives vibrating screen 3 to screen at a frequency of 60Hz. Broken cores larger than 5mm are intercepted, and corn kernels fall through the screen holes 301. Three-stage air separation: Fan 5 blows at a wind speed of 5m / s to remove residual debris, and finally the corn cob falls from the corn cob channel and the corn kernel falls from the corn kernel channel; Monitoring and Adjustment: Observe the real-time separation efficiency (default ≥200kg / h) displayed on the touch screen of the human-machine interface 601. If a blockage warning occurs, the equipment can be paused.
[0026] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
