DETAILED DESCRIPTION

[0019] Please refer to Figures 1-4The utility model provides a technical scheme: a kind of double-spectrum identification module mounting rack of grain color sorter, including the support structure of installation support plate 1 and suspension bracket 2, the suspension bracket 2 is used to install spectrum camera 3, and heat dissipation component for cooling spectrum camera 3 is installed in installation support plate 1 inside, and the guide assembly for magnetically attracting and positioning spectrum camera 3 is installed in suspension bracket 2 inside, heat dissipation component includes heat dissipation plate 5 and cooling fan 9, heat dissipation plate 5 is located at the bottom end of cooling fan 9, and the air outlet end of cooling fan 9 is towards spectrum camera 3 and forms airflow barrier structure.

[0020] Installation support plate 1 and suspension bracket 2 form support structure, and installation support plate 1 and suspension bracket 2 are installed and fixed respectively to heat dissipation component and camera component, and suspension bracket 2 is installed on the both sides or one side of material transmission channel, and is adjusted according to actual demand, and installation support plate 1 is internally provided with multiple installation grooves 15, the gap of this installation groove 15 is same with the distribution gap of heat dissipation fin of heat dissipation plate 5, heat dissipation plate 5 can be installed above installation support plate 1 and is fixed by bolt assembly, and heat pipe 11 is further arranged between installation support plate 1 and suspension bracket 2, and the recess for heat pipe 11 is provided in the heat dissipation fin of the bottom of heat dissipation plate 5, so that heat pipe 11 can transfer the heat of spectrum camera 3 to heat dissipation component, and heat dissipation component includes heat dissipation plate 5, cooling fan 9, first heat conduction plate 10 and second heat conduction plate 16, the air inlet 8 of mounting seat 6 and the upper end air outlet are respectively provided with dustproof net of corresponding size, the joint part between first heat conduction plate 10, second heat conduction plate 16 and cooling fan 9 and spectrum camera 3 can be filled with silicon grease to improve heat conduction efficiency, and cooling fan 9 cooperates with heat dissipation plate 5 to cool the heat of second heat conduction plate 16, to ensure that spectrum camera 3 is in suitable temperature environment;

[0021] The outer side of suspension bracket 2 is provided with guide rail 14, and guide rail 14 is in "T" shape structure, one end of guide rail 14 is inserted into the positioning groove 4 of suspension bracket 2, and when the vertical part of guide rail 14 is attached to the outer wall of suspension bracket 2, the negative magnetic block 13 on the back of suspension bracket 2 is attracted to the positive magnetic block 12 in the inside of suspension bracket 2, so that the left and right positioning and installation can be achieved, the back structure of spectrum camera 3 is made of copper, which can conduct heat to the internal modules of spectrum camera 3 on the one hand, and can isolate the influence of positive magnetic block 12 on the inside on the other hand.

[0022] While cooling heat conduction component, the air outlet end of cooling fan 9 is towards spectrum camera 3, and the image acquisition part of spectrum camera 3 is located at the top end of cooling fan 9, and the wind force generated by cooling fan 9 can form an airflow barrier in front of spectrum camera 3, which can avoid the floating of grain particles in front of spectrum camera 3, and also reduce the adhesion of grain particles on the lens surface of spectrum camera 3, and the lens of spectrum camera 3 is provided in conical concave shape, which can form a conical dust cover, to further reduce dust adhesion.

[0023] The heat generated during the operation of the spectral camera 3 is first rapidly conducted to the first heat-conducting plate 10 through the copper structure on the back of the spectral camera 3, and the high thermal conductivity of copper can reduce the thermal resistance and avoid the accumulation of heat inside the camera. The heat absorbed by the first heat-conducting plate 10 is transmitted to the second heat-conducting plate 16 through the heat-conducting pipe 11. The heat-conducting pipe 11 is filled with phase-change working medium. Through the cycle process of absorbing heat by evaporation of liquid working medium and releasing heat by condensation of gaseous working medium, high-efficiency heat transfer is achieved. The second heat-conducting plate 16 uniformly distributes the heat to the heat dissipation fins of the heat dissipation plate 5. The heat dissipation fins accelerate the radiation of heat to the air by increasing the surface area. At the same time, the gap between the heat dissipation fins and the mounting groove 15 matches, forming a directional flow channel. After the heat dissipation fan 9 is started, the airflow is sucked from the annular air inlet 8 of the mounting seat 6. Part of the airflow generated by the heat dissipation fan 9 is directly directed towards the front end of the lens of the spectral camera 3, forming a continuous positive pressure airflow barrier. This airflow can prevent grain dust from approaching the lens and blowing away the particles that have already adhered. The lens of the spectral camera 3 adopts a conical concave structure, which cooperates with the airflow to form a vortex effect, further guiding the dust to the sides to avoid deposition in the central area of the lens.

[0024] The guiding system realizes precise installation and rapid adjustment of the spectral camera 3 through magnetic positioning and guide rail sliding, ensuring optical alignment accuracy. The "T" shaped vertical part of the guide rail 14 is embedded in the positioning groove 4 of the hanging bracket 2, and the horizontal part slides along the inner wall of the positioning groove 4 of the hanging bracket 2. The sliding track of the guide rail 14 is constrained by the positioning groove 4, ensuring that the spectral camera 3 can only translate in the preset direction. By sliding the guide rail 14, when the spectral camera 3 moves to the target position, the negative magnetic block 13 on the back of the spectral camera 3 is attracted to the positive magnetic block 12 inside the hanging bracket 2 through magnetic force, achieving instantaneous locking.

[0025] The copper back plate of the spectral camera 3 not only conducts heat out, but also forms an electromagnetic shielding layer to avoid interference of the magnetic field of the magnetic blocks with the internal electronic components. The heat-conducting pipe 11 is connected to the first heat-conducting plate 10 in the groove of the hanging bracket 2 and the second heat-conducting plate 16 at the bottom of the heat dissipation plate 5. This design breaks through the physical separation of the support structure, realizing cross-component heat transfer. A groove matching the shape of the heat-conducting pipe 11 is provided at the bottom of the heat dissipation plate 5. The heat-conducting pipe 11 is tightly fitted with the groove wall through bolt compression, reducing the contact thermal resistance.

[0026] High-thermal-conductivity silicone grease is filled in the contact surface between the first heat-conducting plate 10 and the spectral camera 3, and the contact surface between the second heat-conducting plate 16 and the heat dissipation plate 5. The silicone grease fills the microscopic uneven gaps, forming a continuous heat-conducting layer and improving the heat conduction efficiency. A phase-change heat-conducting material such as a paraffin-based composite material is provided between the heat dissipation fan 9 and the first heat-conducting plate 10. When the temperature rises, the material undergoes solid-liquid phase change to absorb heat. When the temperature decreases, it solidifies and releases heat, balancing the instantaneous heat load fluctuations.
