Description

[0025] like Figure 1-Figure 2 As shown, the present invention provides a technical solution: a fluidized bed type waxberry cleaning device, comprising: a fluidized bed cleaning mechanism 2, for receiving waxberries and performing fluidized cleaning; the fluidized bed cleaning mechanism 2 comprises a fluidized bed body 201; a cleaning tank 203 is arranged in the fluidized bed body 201, and a multi-section conveyor belt for conveying waxberries is arranged in the cleaning tank 203; a discharge port 209 and a water inlet 207 are respectively arranged at both ends of the fluidized bed body 201, and the fluidized bed body 201 is at the water inlet 207. 07 is provided with a feed port 202 at the top of one end, and a drain port 208 is provided at the bottom of the fluidized bed 201; a plurality of evenly arranged nozzles 210 are provided on the outer side of the bottom of the fluidized bed 201, and the nozzles 210 are aligned with the internal cleaning tank 203, and the nozzles 210 are connected to the air compressor 212 through the transmission water pipe 211; the present invention sprays the liquid inside the cleaning tank 203 through the provided nozzles 210, so that the liquid flows and rolls rapidly, thereby accelerating the separation of fruit fly larvae and impurities on the surface of bayberry.

[0026] The present invention injects clean water as a fluid medium into the fluidized bed 201, and accelerates the flow of the fluid medium by using multiple nozzles 210 to spray air, so that the bayberries in the fluidized bed 201 form a liquid-like flow state under the push of the fluid medium, and quickly rub against the fluid to accelerate the separation of stubborn dirt and impurities on the surface of the bayberries and fruit fly larvae, thereby achieving a flexible cleaning effect for the bayberries.

[0028] Among them, nets are set on both sides of the third conveyor belt 206, the second conveyor belt 205 and the first conveyor belt 204 to prevent the bayberries from falling; the nets can limit the bayberries on the conveyor belts to prevent the bayberries from falling into the bottom of the cleaning tank 203 when the nozzle 210 sprays air.

[0029] The transmission water pipe 211 is provided with a valve for controlling the air flow size of the nozzle 210 .

[0030] The present invention can also add detergent from the water inlet 207, and the mixture of detergent and clean water can accelerate the shedding of impurities on the surface of the bayberry and fruit fly larvae.

[0032] The second transmission and bad fruit screening mechanism 3 has the same structure as the first transmission and bad fruit screening mechanism.

[0033] like Figure 4 As shown, the first transmission and bad fruit screening mechanism includes a support 103, on which a fourth conveyor belt 102 is arranged, a connecting bracket 105 is arranged at the end of the fourth conveyor belt 102, an image recognition module 106 is arranged on the connecting bracket 105, and the image recognition module 106 is aligned with the end of the fourth conveyor belt 102; an angle adjustment bracket 107 is arranged on the support 103 at the bottom of the end of the fourth conveyor belt 102, and a nozzle 108 is arranged on the angle adjustment bracket 107; the nozzle 108 is aligned with the arc line on which the bayberry normally falls at the end of the fourth conveyor belt 102; a material storage box 109 is arranged at the bottom of the end of the fourth conveyor belt 102, and a bad fruit storage box 110 is arranged on the side of the material storage box 109 away from the fourth conveyor belt 102; a polymerization component for aggregating bayberries is also arranged on the top of the surface of the fourth conveyor belt 102, and the polymerization component allows the bayberries to fall only in a straight line, so that the nozzle 108 can spray the bad fruits more accurately.

[0034] Baffles 104 are provided on both sides of the fourth conveyor belt 102 , and the baffles 104 can prevent the bayberries from falling off the fourth conveyor belt 102 .

[0035] The polymer assembly includes two limit baffles 14 and a plurality of baffle support rods 15 for fixing the limit baffles 14. One end of the two limit baffles 14 is respectively fixed to the inner side of the baffles 104 on both sides of the fourth conveyor belt 102 near the feeding end. The other end of the two limit baffles 14 is fixed to the unloading end of the fourth conveyor belt 102 through the baffle support rods 15 connected to the baffles 104. The distance between the ends of the two limit baffles 14 at the unloading end of the fourth conveyor belt 102 is less than the second preset distance (the second preset distance is determined according to the situation, generally greater than the diameter of one bayberry and less than the diameter of two bayberries). The nozzle 108 is externally connected to the air compressor 212, and the air compressor 212 provides compressed air. The nozzle 108 is provided with an electric valve for controlling the closing of the nozzle 108. The nozzle 108 is aligned with the bottom between the ends of the two limit baffles 14 at the unloading end of the fourth conveyor belt 102.

[0036] Among them, the image recognition module 106 is composed of a camera and an image processing module. The camera is aimed between the ends of the two limit baffles 14 at the unloading end of the fourth conveyor belt 102. The image processing module has a built-in target detection algorithm. The target detection algorithm can use a YOLO series model, such as YOLOv8, YOLOv5, etc., or a deep learning model, such as a convolutional neural network (CNN), a generative adversarial network (GAN), etc.

[0037] Before use, a large number of bayberry images are collected, including images of good and bad fruits, and are annotated, and the annotated images constitute a data set; the data set is used to train the target detection algorithm in the image processing module, and the trained target detection algorithm is used to identify the bayberries that fall from the fourth conveyor belt 102 after being aggregated by the limiting baffle 14 and reaching the unloading end. When bad fruits are identified, a signal is sent to open the electric valve on the nozzle 108, and the nozzle 108 sprays compressed air to blow the bad fruits into the bad fruit storage box 110, while the good bayberries fall normally into the material storage box 109.

[0038] Among them, the angle adjustment bracket 107 can adjust the angle of the nozzle 108; by using the image recognition module 106 to identify bad bayberries, and using the nozzle 108 to spray air to screen out the bad fruits, the bayberries that need to be processed can be pre-processed to facilitate subsequent bayberry cleaning.

At the same time, the cleaning conduit 11 is used to connect the water pump to pump water to the cavity in the cleaning rod 10, and spray it onto the screen 5 through the nozzle to rinse the bayberry cleaned by the fluidized bed cleaning mechanism 2, so that the debris and fruit flies still attached to the surface of the bayberry after cleaning by the fluidized bed cleaning mechanism 2 are washed away, and the inclined supporting frame 4 can make the bayberry after solid-liquid separation slide into the second transmission and bad fruit screening mechanism 3 for secondary bad fruit screening, and finally recycled; the vibration component 6 can vibrate and dredge the bayberry stuck on the screen 5; the set flushing mechanism can flush away the debris and fruit flies still attached to the surface of the bayberry after cleaning by the fluidized bed cleaning mechanism 2, thereby improving the cleanliness of the bayberry.
