In addition, the spacing adjusting assembly and the height adjusting assembly can also be implemented by using existing structures in addition to the above-mentioned implementation.

[0045] Through the above setting, when the bananas enter the sterilization station, the bananas are sensed by the light barrier photoelectric sensor located at the sterilization station, the preservative liquid is extracted from the liquid storage tank by the high-pressure atomizing pump, and is uniformly sprayed on the cut of the comb handle of the bananas through the nozzle 505.

[0051] In addition to the above structure, the suspension type conveying device 2 can also adopt the existing suspension conveyor.

[0052] In addition, the running state of the control system can be displayed in real time through the man-machine interface, the rotating speed and the beat of the servo motor can be adjusted online, and thus the cleaning time, the air drying time and the sterilization time can be set. Figures 1-18 The working principle of the suspension type banana cleaning and sterilizing automatic equipment is as follows.

[0053] Firstly, when the bananas (together with the profiling trays 9) are conveyed to the feeding station by the feeding conveying line 1B, the suspension type conveying mechanism conveys one group of hanging baskets 8 to the feeding station, the feeding driving mechanism drives the feeding push plate 101 to move downward, then the feeding horizontal driving mechanism 103 drives the feeding push plate 101 to move, so that the bananas (together with the profiling trays 9) on the feeding conveying line 1B are pushed onto the hanging baskets 8.

[0054] Then, the hanging conveying device 2 conveys the bananas into the cleaning tank 301, and the horizontal conveying pump works to convey the cleaning liquid through the conveying pipeline into the longitudinal jet nozzles 304 and the transverse jet nozzles 305 on both sides of the cleaning tank 301, so that the opposite jet flows are generated in the longitudinal jet nozzles 304 and the transverse jet nozzles 305 on both sides of the cleaning tank 301, and the bananas on the hanging baskets 8 are washed; since the longitudinal jet flow is introduced, three-dimensional double-vortex water flow movement can be realized; the effects of the transverse and longitudinal jet flows are more obvious at the middle and upper stream positions of the cleaning tank 301, and therefore the cleaning effect of the bananas in the cleaning area is the best. In addition, the flow is split during the double-vortex flow, so that the flow damage is small; the maximum impact force of a single transverse jet nozzle 305 is smaller than that of a single-vortex flow; the pressure and outlet flow rate of the jet flow can be measured and adjusted through the flow meter to reduce the impact force of the cleaning liquid (which can be chlorine water or preservative liquid) on the surface of the bananas; at the same time, the float level controller and the turbidity sensor are added to collect data to realize real-time detection of the water level height, turbidity and running state, so as to realize self-adaptive water circulation filtration, thereby further reducing the water consumption of the cleaning tank 301 and unifying the cleaning time of the bananas on the hanging baskets 8.

[0055] Subsequently, the hanging conveying mechanism continues to drive the cleaned bananas to move to the air-drying station, and when the bananas reach the air-drying station, the air blower sucks in, compresses and blows out air from two groups of symmetrically arranged air knives 402, so as to remove the residual cleaning liquid on the surface of the bananas.

[0056] Then, the hanging conveying mechanism continues to drive the cleaned bananas to move to the sterilization station, and when the bananas enter the sterilization station, the anti-corrosion liquid is extracted from the liquid storage tank by the high-pressure atomizing water pump when the bananas are sensed by the opposite light sensors located at the sterilization station, and is uniformly sprayed on the incision of the comb handle of the bananas through the nozzle 505 (such as a universal high-pressure spray head). The bananas need to stay in the sterilization station for a certain period of time, and the purpose is to make the anti-corrosion liquid fully sprayed on the incision of the comb handle of the bananas.

[0057] Finally, the hanging conveying device 2 continues to drive the cleaned bananas to move to the discharging station, and the discharging horizontal driving mechanism 602 drives the discharging push plate 601 to push the bananas located at the discharging station together with the profiled tray 9 to the discharging conveying line 6B; the discharging conveying line 6B conveys the bananas to the packaging station 7, and the bananas are automatically packaged through the packaging device, or workers pack the bananas according to the grade standard, and the empty profiled tray 9 returns to the feeding station along with the discharging conveying line 6B to wait for re-feeding.

[0058] The above is the preferred embodiment of the present application, but the embodiment of the present application is not limited by the above, and any change, modification, substitution, combination, simplification, etc. made without departing from the spirit and principles of the present application shall be equivalent replacement and included in the protection scope of the present application.
