DETAILED DESCRIPTION

[0040] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments in conjunction with the accompanying drawings:

[0041] refer to Figure 1-5 , a cooking and drying mechanism suitable for fruits and vegetables, comprising:

[0042] Material conveyor belt 1;

[0043] A material paving hopper 2 is arranged at the feeding end of the material conveyor belt 1, and the material paving hopper 2 includes a material frame and a material paving plate arranged at the material outlet of the material frame;

[0044] A drying chamber 3 is arranged around the periphery of the material conveyor belt 1, a plurality of drying mechanisms 31 are arranged inside the drying chamber 3 facing the belt surface of the material conveyor belt 1, and the drying chamber 3 is provided with a ventilation mechanism 4;

[0045] In this embodiment, the material hopper 2 can be composed of a material frame and a material paving plate. The bottom of the material frame is provided with an opening, and the material paving plate blocks the upper area of ​​the opening at a certain height, so as to control the discharge speed of the material hopper 2 and adapt to the diameter of fruits and vegetables. At the same time, the material hopper 2 can also be provided with a vibration mechanism to prevent it from being blocked. The fruits and vegetables on the material conveyor belt 1 are heated by the drying mechanism 31 in the drying chamber 3, which can be low-temperature heating or high-temperature heating. The drying chamber 3 encloses a certain space outside the material conveyor belt 1 to play a role in heat preservation. The ventilation mechanism 4 dehumidifies by exhausting air, and evaporates the moisture on the surface of the fruits and vegetables and quickly takes it away.

[0046] In order to fully dry the material, the conveying speed of the material conveyor belt 1 is relatively slow, generally about 2 cm / min.

[0047] A visual mechanism (not shown) is disposed above the feeding end of the material conveyor belt 1, and the visual mechanism is directed toward the belt surface of the material conveyor belt 1 to acquire images and identify the area where fruits and vegetables gather;

[0048] In this embodiment, the visual mechanism can be an existing technology, and after collecting images, the network can be initialized using a pre-trained model (such as COCO pre-trained weights), and fine-tuned for the fruit and vegetable data set to accelerate training and improve accuracy, thereby obtaining a model dedicated to identifying the aggregation of fruits and vegetables. According to the identified area where fruits and vegetables gather, the fruit and vegetable dispersing mechanism 5 can be accurately controlled to reach the area and work.

[0049] The fruit and vegetable dispersing mechanism 5 is arranged above the rear end of the material conveyor belt 1 corresponding to the visual mechanism. The fruit and vegetable dispersing mechanism 5 includes a cover cylinder 51. The bottom of the cover cylinder 51 is inclined toward its axis. The inner wall of the cover cylinder 51 is provided with a fruit and vegetable temporary storage cavity 52. ​​The lower end of the fruit and vegetable temporary storage cavity 52 is open. The fruit and vegetable temporary storage cavity 52 is provided with a threaded retaining strip 54 on the bottom side thereof. The threaded retaining strip 54 is provided with a plurality of fruit and vegetable ascending grooves 55. The fruit and vegetable ascending groove 55 is provided with a one-way baffle 56 that passes one-way from bottom to top. The top of the cover cylinder body 51 is provided with a first air inlet 53. When the first air inlet 53 takes in air, the fruits and vegetables on the bottom of the cover cylinder pass through the one-way baffle 56 to reach the fruit and vegetable temporary storage chamber 52. When the first air inlet 53 stops taking in air, the fruits and vegetables are output one by one downward along the threaded baffle 54 to the bottom of the cover cylinder body 51. A controllable valve 521 is provided at the top of the fruit and vegetable temporary storage chamber 52.

[0050] The fruit and vegetable dispersing mechanism 5 is one of the core improvements of the present application. First, after the cover cylinder 51 is lowered, it can cover the fruits and vegetables located on the material conveyor belt 1, and together with the material conveyor belt 1, form a certain shielding space; then, a gas path such as the first air inlet 53, the bottom end of the cover cylinder 51, and the fruit and vegetable temporary storage chamber 52 is formed inside the cover cylinder 51. The lower end of the fruit and vegetable temporary storage chamber 52 is open, so round or granular fruits and vegetables can enter the interior of the fruit and vegetable temporary storage chamber 52 through the opening of the fruit and vegetable temporary storage chamber 52; the threaded baffle 54 divides the fruit and vegetable temporary storage chamber 52 to form a spirally ascending channel that is isolated from each other from top to bottom, and at the same time cooperates with the fruit and vegetable ascending groove 55 and the one-way baffle 56. When air is taken in at the first air inlet 53, the fruits and vegetables can be blown up along the inclined end of the bottom of the cover cylinder 51 to the bottom of the fruit and vegetable temporary storage chamber 52, and then the fruits and vegetables pass through the fruit and vegetable ascending groove 55 of the fruit and vegetable temporary storage chamber 52 and enter the top of the threaded baffle 54, as shown in FIG. Figure 6-7As shown; after the first air inlet 53 stops intake, the one-way baffle 56 blocks the fruit and vegetable ascending groove 55, and the fruits and vegetables cannot pass through the fruit and vegetable ascending groove 55 to descend. At this time, the fruits and vegetables spirally roll down along the threaded baffle 54, so that the fruits and vegetables can be output one by one from the bottom end of the fruit and vegetable temporary storage chamber 52, as shown Figure 8 As shown, the situation of stacking and convergence again is reduced.

[0051] The three-axis driving mechanism 6 is used to drive the fruit and vegetable dispersing mechanism 5 to the area where fruits and vegetables are gathered, and lower the fruit and vegetable dispersing mechanism 5 to the area where fruits and vegetables are gathered.

[0052] The three-axis driving mechanism 6 can adopt the existing technology to realize the movement of the fruit and vegetable dispersing mechanism 5 in the three axes of X, Y and Z.

[0053] Furthermore, the drying mechanism 31 is an electric heating film glass plate, and the electric heating film glass plate is connected to an external power supply through a corresponding electric controller.

[0054] The electric heating film glass plate comprises a glass substrate and a semiconductor electric heating film sprayed on the bottom side of the glass substrate. The two sides of the semiconductor electric heating film are respectively connected to corresponding electrodes, and the electrodes are connected to an external power supply through corresponding electric controllers. The far-infrared waves formed by the electric heating film glass plate can act on the granular activated carbon material in a tilted downward state. Therefore, the electric heating film glass plate can not only maintain but also significantly improve the contact rate between the far-infrared wave and the material, so as to further improve the utilization rate of thermal energy and the thermal radiation effect on the basis of reducing the heat energy loss. The electric heating film glass plate is a direct adoption of the existing technology.

[0055] Furthermore, the width of the one-way blocking piece 56 is greater than the diameter of the fruits and vegetables, and the width of the fruit and vegetable temporary storage cavity 52 is 1.2-1.4 times the diameter of the corresponding fruits and vegetables.

[0056] Preferably, the width of the fruit and vegetable temporary storage cavity 52 is 1.2-1.4 times the diameter of the fruit and vegetable. In this case, after the fruits and vegetables enter the fruit and vegetable temporary storage cavity 52, they can be regularly arranged in a single row to prevent the fruits and vegetables from being arranged front to back or side to side. At the same time, the space provides sufficient rotation space for the fruits and vegetables, so that the fruits and vegetables will not be blocked by the inner wall of the fruit and vegetable temporary storage cavity 52 when rolling downward.

[0057] Furthermore, an annular air outlet 57 is provided on the periphery of the bottom surface of the cover cylinder body 51 , and the air outlet 57 is provided with an air outlet nozzle inclined toward the axis of the cover cylinder body 51 , and the air outlet 57 is connected to an air source.

[0058] In this embodiment, when the annular air outlet 57 releases air, the fruits and vegetables below it can be blown away from the bottom of the side wall of the cover cylinder 51 through the air outlet nozzle, thereby preventing the cover cylinder 51 from being blocked by the fruits and vegetables when it descends and from being unable to completely descend and adhere to the belt surface of the material conveyor belt 1.

[0059] At the same time, the air outlet 57 is inclined toward the axis of the cover cylinder 51, so that the fruits and vegetables under the cover cylinder 51 can be gathered to its center as much as possible. When air is taken in by the first air inlet 53, it can be blown toward the center where the fruits and vegetables gather, so that they can move more evenly radially toward the cover cylinder 51.

[0060] Furthermore, the fruit and vegetable temporary storage chamber 52 is provided with a blocking net 59 , and the blocking net 59 is arranged above the threaded blocking strip 54 .

[0061] Furthermore, the blocking net 59 is a spiral structure matched with the threaded blocking strip 54, and the distance between the threaded blocking strip 54 and the blocking net 59 is 1.2-1.4 times of the diameter of the corresponding fruits and vegetables.

[0062] The blocking net 59 can block the fruits and vegetables from passing through, and can allow gas to pass through. In addition, the threaded baffle 54 and the blocking net 59 are both spirally ascending structures, and the two are arranged vertically. After the fruits and vegetables enter the threaded baffle 54, they are blocked by the blocking net 59 and fall on the threaded baffle 54. The distance between the threaded baffle 54 and the blocking net 59 is 1.2-1.4 times the diameter of the corresponding fruits and vegetables. Therefore, the space can only accommodate a single row of fruits and vegetables distributed vertically, thereby ensuring that the fruits and vegetables form a single row of spirally ascending arrays.

[0063] Furthermore, a controllable valve 521 is provided at the top of the fruit and vegetable temporary storage chamber 52 , and a second air inlet 58 is provided at the top of the fruit and vegetable temporary storage chamber 52 , and the second air inlet 58 is connected to an air source.

[0064] When fruits and vegetables rise and are temporarily stored in the fruit and vegetable temporary storage chamber 52, if they are some small granular fruits and vegetables, such as green beans and black beans, the speed of their output from the fruit and vegetable temporary storage chamber 52 is slow due to their own gravity, so the output speed of fruits and vegetables can be accelerated by gently blowing air into the fruit and vegetable temporary storage chamber 52 through the second air inlet 58. The controllable valve 521 can remain in a closed state when the second air inlet 58 blows air inward, so that the gas can flow downward along the threaded retaining strip 54, and remain in an open state when the first air inlet 53 takes in air, so that the gas can flow upward along the threaded retaining strip 54, thereby realizing multiple functions.

[0065] Furthermore, the visual mechanism includes a camera and a control system. After the control system acquires the image captured by the camera, it executes:

[0066] After removing the background of the image, binarization is performed, and then a Gaussian kernel density estimation algorithm is used to identify the clustered area, and the center of mass of the clustered area is identified and the coordinates of the center of mass are transmitted to the three-axis driving mechanism 6.

[0067] In this embodiment, fruits and vegetables may have different colors, shapes, and sizes, and may overlap in the image, but the color of the material conveyor belt 1 is fixed, so the background of the image can be removed by removing the colors within a certain color range to obtain an image that only retains fruits and vegetables. After binarization, the pixel range of fruits and vegetables can be converted to black, and the pixels outside fruits and vegetables can be converted to white. The average distance and aggregation shape between fruits and vegetables can be calculated by the Gaussian kernel density estimation algorithm, where the Gaussian kernel density estimation algorithm is a direct adoption of the prior art.

[0068] After the centroid of the gathering area is identified to obtain its coordinates, the coordinates are given to the three-axis driving mechanism 6, so that the three-axis driving mechanism 6 transports the fruit and vegetable dispersing mechanism 5 to the bottom of the position, and the cover cylinder 51 can be accurately shielded above the gathered fruits and vegetables.
