TECHNICAL FIELD

[0001] The present application relates to the technical field of conveying equipment, in particular to an intelligent conditioning conveyor. BACKGROUND

[0002] Bulk grain is prone to moisture loss, insect infestation, mold, etc. during long-distance transportation through different temperature and humidity regions, so it needs to be sprayed with medicine before loading. Currently, manual spraying is generally used on domestic conveyors, and handheld sprayers are used for spraying, which is low in spraying efficiency and cannot guarantee uniform spraying of the medicine amount, and the labor intensity of the operator is large and the working environment is poor.

[0003] Therefore, it is necessary to provide an intelligent conditioning conveyor to solve the above problems. SUMMARY

[0004] The technical problem solved by the present application is to provide an intelligent conditioning conveyor to solve the problems of manual spraying, low spraying efficiency, and inability to guarantee uniform spraying of the medicine amount, and large labor intensity of the operator and poor working environment in the background art.

[0006] Preferably, the protective cover, the diaphragm metering pump and the control box are fixedly connected with the rack of the conveyor, a connecting pipe is fixedly installed at the input end of the diaphragm metering pump, the other end of the connecting pipe extends into the medicine tank, a medicine delivery pipe is fixedly installed at the output end of the diaphragm metering pump, and the other end of the medicine delivery pipe is communicated with multiple spray rods.

[0007] Preferably, the lower end surface of the vertical rod is a spherical surface, and the lower end of the vertical rod abuts against the upper surface of the conveyor belt.

[0009] Beneficial Effects: Compared with existing technologies, this invention provides an intelligent conditioning conveyor. This intelligent conditioning conveyor has a unique structure and is easy to use. Through the core design of "segmented components + multiple sets of alternating nozzles," it achieves precise, all-around spraying of the grain layer, ensuring uniform coverage of the pesticide solution inside and outside the grain layer, effectively preventing localized insect infestation and mold growth. Relying on the linkage control of an ultrasonic ranging sensor and a control box, it automatically converts the grain layer thickness into conveying volume data and dynamically adjusts the frequency of the variable frequency motor of the diaphragm metering pump, achieving real-time matching of the spraying volume with the grain layer thickness and conveying volume. This not only improves spraying efficiency but also significantly reduces the labor intensity of operators. Furthermore, the sealing design of the protective cover and rubber strips effectively prevents the atomized pesticide solution from overflowing, avoiding direct contact with pesticide mist for operators and ensuring their health and safety.

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] Example 1: This Example 1 provides an intelligent conditioning conveyor, which is a direct improvement on an existing conveyor. It has a unique structure. Please refer to [link / reference]. Figures 1-5As shown, the system includes a conveyor 1, an ultrasonic ranging sensor 3 for detecting the thickness of the grain layer, a medicine tank 7 for storing the medicine liquid, a diaphragm metering pump 8 for accurately delivering the medicine liquid, a flow meter 9 for real-time monitoring of the medicine liquid flow rate, and a control box 10 for overall control. The ultrasonic ranging sensor 3, the diaphragm metering pump 8, and the flow meter 9 are all electrically connected to the control box 10. The control box 10 has a built-in PLC controller, which can realize signal reception, data processing, and precise control of the actuators.

[0014] A protective cover 2 is bolted to the top of the conveyor 1. The protective cover 2 not only prevents external debris from entering the conveying area, but also prevents the atomized medicine from spreading and polluting the environment. The lower part of the front and rear sides of the protective cover 2 is provided with slots. The height of the slots is adapted to the height of the conveyor belt of the conveyor 1 to ensure that the grain can smoothly enter and exit the interior of the protective cover 2. The ultrasonic ranging sensor 3 is fixedly installed on the front side of the protective cover 2 by a bracket. Its detection end is vertically facing the surface of the conveyor belt of the conveyor 1, and can detect the thickness information of the grain layer on the conveyor belt in real time.

[0015] A U-shaped frame 5 is fixedly installed inside the protective cover 2 by welding. Multiple spray bars 6 are fixedly installed at equal intervals along the length of the conveyor 1 at the bottom of the U-shaped frame 5. The spray bars 6 are made of stainless steel and have good corrosion resistance. The two ends of the spray bars 6 are sealed with plugs to prevent leakage of the liquid. A flow meter 9 is embedded in the output pipe of the diaphragm metering pump 8. It can collect the liquid flow data in real time and feed it back to the control box 10 to form a closed-loop flow control. Multiple nozzles 13 are fixedly installed at equal intervals along the width of the conveyor 1 at the bottom of the spray bars 6. The nozzles 13 are atomizing nozzles, which can atomize the liquid into fine particles and increase the contact area between the liquid and the grain.

[0016] To achieve layered spraying of the grain layer, a dividing assembly is provided between each pair of adjacent spray bars 6. The dividing assembly includes multiple vertical bars 11 equidistantly arranged along the width direction of the conveyor 1. The vertical bars 11 are fixed to the U-shaped frame 5 by welding, and the vertical bars 11 in the adjacent dividing assemblies are alternately arranged along the width direction of the conveyor 1. The lower end face of the vertical bar 11 is machined into a spherical surface, and the lower end of the vertical bar 11 is close to the upper surface of the conveyor belt of the conveyor 1, which not only ensures the effective division of the grain layer, but also avoids wear on the conveyor belt.

[0017] The protective cover 2, diaphragm metering pump 8, and control box 10 are all fixedly connected to the frame of conveyor 1 by bolts to ensure the stability of the overall structure. A connecting pipe 12 is fixedly installed at the input end of the diaphragm metering pump 8. The other end of the connecting pipe 12 extends to the bottom of the medicine tank 7, and a filter screen is provided at the end of the connecting pipe 12 to prevent impurities in the medicine from entering the pump body and causing blockage. A medicine delivery pipe 4 is fixedly installed at the output end of the diaphragm metering pump 8. The other end of the medicine delivery pipe 4 is connected to multiple spray bars 6 through branch pipes to achieve uniform distribution of medicine.

[0018] Working principle: First, the conveyor 1 is started, and the grain enters the conveyor belt through the trough on the front side of the protective cover 2 and is conveyed forward; the ultrasonic distance sensor 3 detects the thickness of the grain layer on the conveyor belt in real time, converts the detected distance signal into an electrical signal and transmits it to the control box 10; the PLC controller in the control box 10 converts the distance signal into grain layer thickness and conveying volume data through a preset program, and controls the diaphragm metering pump 8 to start according to the data, and adjusts the frequency of its variable frequency motor; the diaphragm metering pump 8 draws liquid medicine from the medicine tank 7, and the liquid medicine is distributed to each spray bar 6 through the connecting pipe 12, flow meter 9, and delivery pipe 4, and finally atomized and sprayed out from the nozzle 13; when the grain passes through the first set of spray bars 6 When the grain is lowered, the first set of nozzles 13 sprays pesticide onto the surface of the grain layer. Then, the grain layer passes through the first set of dividing components, and the vertical rods 11 divide the grain layer into several strip-shaped gaps that run through the grain layer. When the grain layer continues to be conveyed to the bottom of the second set of spray rods 6, the second set of nozzles 13 can accurately spray pesticide onto the grain within the strip-shaped gaps. Through the cooperation of multiple sets of spray rods 6 and dividing components, all-round and uniform pesticide spraying is achieved on the surface and inside of the grain layer. The flow meter 9 monitors the pesticide flow rate in real time and feeds it back to the control box 10. The control box 10 dynamically adjusts the output power of the diaphragm metering pump 8 according to the flow data to ensure that the amount of pesticide sprayed is accurately matched with the thickness of the grain layer and the conveying volume, thereby realizing intelligent quality control.

[0019] Example 2: The difference between this example and Example 1 is as follows: Figure 5 As shown, multiple rubber strips 14 are fixedly installed along the width direction in the slots on both sides of the protective cover 2. The rubber strips 14 are made of elastic and wear-resistant rubber. Adjacent rubber strips 14 are tightly fitted together, and the lower end of the rubber strips 14 is in slight contact with the upper surface of the conveyor belt of the conveyor 1. By setting the rubber strips 14, the rubber strips 14 can be squeezed to form a channel during grain conveying, ensuring that the grain can smoothly enter and exit the protective cover 2. At the same time, the rubber strips 14 can effectively seal the slots of the protective cover 2, preventing the atomized pesticides from overflowing from the slots, reducing pollution to the surrounding environment, and ensuring the health and safety of the staff.
