Description

Technical Field

[0001] This utility model belongs to the field of quality detection and sorting technology for processed tomatoes, and specifically relates to a sorting device for processed tomatoes based on hyperspectral imaging technology. Background Technology

[0002] During mechanized harvesting, tomatoes often contain a significant amount of impurities and low-quality fruit, which makes subsequent sorting difficult and affects the flavor and yield of tomato sauce and other processed products.

[0003] Manual sorting of tomatoes is subjective in terms of color judgment, and the repetitive nature of this task leads to a gradual decrease in worker efficiency. While machine vision can effectively assess the external qualities of tomatoes, such as color and size, it lacks the ability to determine internal qualities like soluble solids, lycopene content, and water content—key indicators for evaluating the quality of processed tomatoes. Therefore, hyperspectral imaging technology, combining spectral and imaging techniques, can simultaneously detect both the internal and external qualities of processed tomatoes.

[0004] Processing tomato harvesters have a large harvesting capacity. Therefore, the technical problem we need to solve is how to design an efficient and stable automated sorting machine installed inside the harvester to separate unqualified processing tomatoes and collect qualified and unqualified processing tomatoes during the harvesting process.

[0058] As an embodiment of the present invention, the sorting component 5 includes a mounting bracket 51, a single-unit unloading actuator 52, and an unloading partition 53.

[0059] The mounting bracket 51 includes a placement frame 511 and a fixing shaft 512, which are fixedly mounted on the mounting frame 1.

[0060] The placement rack 511 is equipped with a single material feeding actuator 52 and a material feeding partition 53.

[0061] The fixed shaft 512 is connected to a rotating pair formed by a deep groove ball bearing 529 and a gear-cylindrical cam transmission assembly 526.

[0062] The single-unit material feeding actuator 52 includes an upper cover 521, a lower cover 522, a motor frame 523, a third drive motor 524, a drive gear 525, a gear-cylindrical cam transmission assembly 526, a roller-slider assembly 527, a material feeding paddle 528, and a deep groove ball bearing 529.

[0063] The upper cover 521, the lower cover 522 and the motor frame 523 are fixedly installed together, and the third drive motor 524 is fixedly installed inside the motor frame 523 to provide rotational power to the drive gear 525.

[0068] As an embodiment of the present invention, the unqualified tomato feeding box 6 is fixedly installed at the bottom of several individual feeding actuators 52 for holding unqualified tomatoes.

[0069] As an embodiment of this utility model, the qualified tomato feeding box 7 is fixedly installed at the guide end of several individual feeding actuators 52 for holding qualified tomatoes.

[0070] The working principle of this new tomato sorting machine:

[0071] The tomatoes to be sorted are gradually guided from the impurity removal double-layer conveying assembly 2 to the starting end of the separating conveying assembly 3. As the conveyor belt 31 continuously guides and conveys the tomatoes to be sorted, the tomatoes to be sorted are slowed down by the first buffer brush 321 through the material separating partition 32, so that the tomatoes to be sorted are separately conveyed on several straight channels and are difficult to get close to each other and stack up. The tomatoes to be sorted then pass under the optical detection assembly 4. At this time, the hyperspectral imaging device 42 can timely collect spectral images and spatial information of the tomatoes, and the control module 44 analyzes the spectral images and spatial information and issues a command to the third drive motor 524 in the sorting assembly 4 to determine whether to operate.

[0072] If the control module 44 determines that a single tomato to be sorted is a qualified tomato, the third drive motor 524 will not operate, and the qualified tomato can smoothly roll over the discharge plate 528 and fall into the qualified tomato bin 7.

[0073] If the control module 44 determines that a single tomato to be sorted is unqualified, the third drive motor 524 operates, the gear-cylindrical cam assembly 526 meshes and rotates, and drives the roller-slider assembly 527 to move linearly along the slider groove of the upper cover 521 and the inclined groove on the lower shaft end of the discharge paddle 528, so that the discharge paddle 528 performs a reciprocating oscillating motion. When the cylindrical cam reaches its far rest, the discharge paddle 528 rotates to form a gap for the unqualified tomatoes to fall through, and the unqualified tomatoes fall into the unqualified tomato bin 6; when the cylindrical cam returns to near rest, the discharge paddle 528 resets.

[0074] During the sorting operation, the discharge baffle 53 ensures the accuracy of sorting and prevents tomatoes from falling from both sides. The second buffer brush 532 can buffer and slow down the tomatoes rolling on the discharge baffle 528, which can prevent the tomatoes from rolling quickly into the qualified tomato bin 7 and causing damage.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made based on the above teachings.
