Description

Technical Field

[0001] The invention relates to a nitrogen insecticide device based on AI in a tobacco flat warehouse, belonging to the technical field of tobacco insecticide. Background Art

[0002] At present, the tobacco manufacturing process in my country has changed. Generally, the tobacco leaves are redried in the redrying factory directly to the cigarette factory. The redried tobacco leaves need to be stored and cured for 1-2 years before they are made into cigarette products to complete the natural aging process of the tobacco leaves and achieve the purpose of improving and enhancing the quality of the tobacco leaves. The aging process is generally carried out in warehouses. There are high-rise warehouses and flat warehouses. Tobacco leaves stored in flat warehouses for a long time are prone to insect infestation, resulting in a decline in the quality of tobacco leaves. The current mainstream methods of pest control include physical pest control methods, such as infrared pest control, microwave pest control, radiation pest control, laser pest control, high-frequency electric heating pest control and other electromagnetic pest control technologies. Some of them are not suitable for tobacco leaf pest control, and some are too expensive. There are also chemical pest control methods, such as fumigation pest control methods such as phosphine (PH3) and methyl bromide (CH3Br). Although this method The insecticidal effect is obvious, but due to the highly toxic, flammable and explosive nature of this type of insecticide, it is easy to cause poisoning and other serious safety accidents during the fumigation process, and it will also cause certain harm to the surrounding environment and humans and animals. Nitrogen is non-toxic and harmless to the human body. At room temperature, nitrogen is a relatively inert gas. 78.1% of the air we breathe daily is nitrogen. Nitrogen has excellent characteristics such as green, safe and pollution-free. Therefore, using nitrogen to fill the inside of a sealed box can effectively kill insects on tobacco.

[0003] The existing AI-based nitrogen insecticide device uses inlet and outlet valves on both sides of the top of the sealed box. Nitrogen can be introduced into the box through the valves through the nitrogen generator, and the inside of the device is equipped with corresponding nitrogen concentration detection devices and temperature detection devices, which are all remotely controlled by AI. However, since the temperature of nitrogen needs to be greater than sixteen degrees to effectively kill insects, the interior needs to be heated when encountering cold weather. It takes a long time to heat the interior to the appropriate temperature, so it needs to be improved. Summary of the invention

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 8 As shown, the present invention provides a nitrogen insecticide device based on AI for a tobacco flat warehouse, comprising a sealed box body 1; an air inlet pipe valve 3 and an exhaust pipe valve 4, which are arranged at the tops of both sides of the sealed box body 1; a heating component 5, which is arranged inside the sealed box body 1 and is located at one end of the inner side of the air inlet pipe valve 3; a driving component 6, comprising a driving frame 601, which is movably installed inside the sealed box body 1 and is located at the top of the heating component 5, and a driving motor 602 located outside the driving frame 601 is arranged on one side of the sealed box body 1, and a driving disc 603 located inside the sealed box body 1 is fixedly sleeved at the output end of the driving motor 602, and a protruding portion on one side of the driving disc 603 extends to the inside of the driving frame 601.

[0022] When the remote AI controls the driving motor 602 to run as a whole, it can drive the driving motor 602 to rotate as a whole. Then, since the protruding part on one side of the driving motor 602 extends to the inner cavity of the driving frame 601, when the driving motor 602 rotates, it can drive the protruding part to move in a circular motion in the inner cavity of the driving frame 601, and can drive the heating component 5 to move as a whole to align with the inner cavity of the intake pipe valve 3.

[0023] like Figure 3 and Figure 4 As shown, the heating assembly 5 includes a heating plate 501, a slide groove 502 and a slider 503; The heating plate 501 is movably installed inside the sealed box body 1 and is located at the inner end of one side of the intake pipe valve 3. The slide groove 502 is opened inside the sealed box body 1 and is located directly above the heating plate 501. The slider 503 is fixedly installed on the top of the sealed box body 1 and is located inside the slide groove 502.

[0024] By adopting the above solution, the slider 503 is provided, and when the heating plate 501 moves as a whole, the slider 503 can move in the horizontal direction under the limiting effect of sliding in the slide groove 502 .

[0025] like Figure 8 As shown, a rolling door 2 is provided on one side of the sealed box body 1 , and a baffle 7 is provided on the bottom of one side of the heating plate 501 of the sealed box body 1 .

[0026] With the above solution, through the design of the rolling door 2, the operator can smoothly open the seal of the sealed box body 1 through the rolling door 2 up and down, so as to take and place the tobacco later.

[0027] like Figure 3 and Figure 8 As shown, the baffle 7 is made of rubber, and a lifting mechanism 8 located on one side of the heating plate 501 is provided inside the sealing box body 1 .

[0028] The above scheme is adopted: the baffle bar 7 is made of rubber and has corresponding deformability. When the heating plate 501 is located at the top as a whole, the baffle bar 7 can shield the cavity at the bottom of the heating plate 501 to prevent nitrogen from entering. When the heating plate 501 moves downward as a whole, it squeezes and pushes the baffle bar 7 to deflect as a whole, so that the heating plate 501 moves downward smoothly as a whole.

[0029] like Figure 3 As shown, the lifting mechanism 8 includes a lifting slide 801, a lifting motor group 802, a moving block 803 and a clamping assembly 804; The lifting slide 801 is arranged inside the sealing box body 1 and is located on one side of the heating plate 501. The lifting motor group 802 is fixedly installed inside the lifting slide 801. The moving block 803 is threadedly sleeved on the output end surface of the lifting motor group 802. The clamping assembly 804 is arranged on one side of the heating plate 501 and is located inside the moving block 803.

[0030] The above solution is adopted: by setting up a lifting motor group 802, when the operator remotely controls the overall operation of the lifting motor group 802 through AI, the output end of the lifting motor group 802 can be rotated to drive the entire moving block 803 to move up and down.

[0031] like Figure 3 As shown, the clamping assembly 804 includes a fixing block 8041, a clamping block 8042 and a first power spring 8043; The fixed block 8041 is fixedly installed on one side of the heating plate 501 , and the clamping block 8042 is movably installed inside the movable block 803 and is located outside the fixed block 8041 . The clamping block 8042 is elastically connected to the inner cavity of the movable block 803 through the first power spring 8043 .

[0032] By adopting the above solution, the elastic force of the first power spring 8043 can push the two clamping blocks 8042 to move toward each other, so that the outer end of the moving block 803 can be clamped and connected by the inner end of the clamping block 8042.

[0033] like Figure 3 As shown, the inner side of the clamping block 8042 adopts a sloped design.

[0034] The above solution is adopted: through the inclined surface design on the inner side of the clamping block 8042, when the heating plate 501 moves and resets, the fixing block 8041 will squeeze and push the inclined surface on the inner side of the clamping block 8042, thereby making the two clamping blocks 8042 move smoothly in opposite directions as a whole.

[0035] like Figure 6 As shown, a shielding assembly 9 located below the heating plate 501 is provided inside the sealed box body 1, and the shielding assembly 9 includes a shielding plate 901, an arc spring 902 and a power arc block 903; The baffle plate 901 is hinged inside the sealed box body 1 and is located outside the bottom of the heating plate 501. The arc spring 902 is fixedly installed in the inner cavity of the sealed box body 1 and is located at the bottom inside the baffle plate 901. The power arc block 903 is fixedly installed at the other end of the arc spring 902.

[0036] By adopting the above solution: by providing the arc spring 902, when the baffle plate 901 is released as a whole, the elastic force of the compressed arc spring 902 can be released, thereby smoothly pushing the power arc block 903 to drive the baffle plate 901 as a whole to flip and open.

[0037] like Figure 7 As shown, a locking assembly 10 is disposed inside the sealing box body 1 and is located in the middle of the bottom end of the shielding plate 901. The locking assembly 10 includes a locking block 101 and a second power spring 102; The locking block 101 is movably installed inside the sealing box body 1 and is located in the middle of the bottom end of the baffle plate 901. The second power spring 102 is fixedly installed at the bottom end of the locking block 101, and one side of the top of the locking block 101 extends to the inside of the baffle plate 901.

[0038] The above solution is adopted: by providing a locking block 101, when the heating plate 501 moves downward as a whole, the locking block 101 can be pushed to move downward as a whole, so that one side of the top of the locking block 101 is separated from the inside of the baffle plate 901, and the locking and fixing effect on the baffle plate 901 can be released.

[0039] like Figure 7 As shown, the other end of the second power spring 102 is fixedly connected to the inside of the sealing box body 1.

[0040] The above scheme is adopted: by providing a second power spring 102, when the locking block 101 moves downward as a whole, the second power spring 102 will be compressed, and when the heating plate 501 is reset upward as a whole, the elastic force of the second power spring 102 can be released, thereby pushing the locking block 101 to move upward and reset as a whole.

[0041] The working principle and use process of the present invention: First, when encountering low temperature conditions, the drive motor 602 can be controlled by remote AI to run. The operation of the drive motor 602 can drive the drive disc 603 to rotate, and then the drive frame 601 can be driven as a whole to pull the slider 503 and the heating plate 501 to one side as a whole, until the middle of the heating plate 501 is aligned with the inner cavity of the intake pipe valve 3. At this time, the operator can remotely control the heating plate 501 for heating through AI, and then the nitrogen generator can be used to introduce and heat nitrogen through the intake pipe valve 3 until it completely fills the interior of the sealed box body 1, and then the tobacco inside the sealed box body 1 can be treated with insecticides.

[0042] Then, when the operator needs to repair the heating plate 501 as a whole, the driving motor 602 can be started to drive the driving disk 603 to rotate and drive the driving frame 601, the slider 503 and the heating plate 501 to move and reset as a whole. At this time, the fixed block 8041 installed on one side of the heating plate 501 will squeeze and push the inclined surface of the clamping block 8042 to drive the two clamping blocks 8042 to move away from each other until the fixed block 8041 is completely moved into the lifting slide 801. Through the elastic force of the first power spring 8043, the two clamping blocks 8042 can be pushed towards each other to clamp the fixed block 8041, so that the heating plate 501 and the moving block 803 are clamped and connected.

[0043] Afterwards, the overall operation of the lifting motor group 802 can be controlled by remote AI to drive the moving block 803, the clamping assembly 804 and the heating plate 501 to move downward as a whole, until the heating plate 501 moves to the bottom, and the bottom end of the heating plate 501 pushes the locking block 101 to move downward as a whole, and the top of one end of the locking block 101 will be separated from the inside of the baffle plate 901, so that the elastic force of the arc spring 902 can be released smoothly, and the power arc block 903 can be pushed to drive the baffle plate 901 to flip open as a whole, and finally the heating plate 501 can be smoothly repaired.

[0044] It also includes a nitrogen condition control unit, wherein the nitrogen condition control unit includes: A nitrogen concentration measuring instrument disposed in the sealed box, the nitrogen concentration measuring instrument comprising a data sensor; A 5G CPE terminal is arranged outside the sealed box body, and the 5G CPE terminal is connected to the data sensor; The 5G CPE terminal transmits the measurement data to the data processing unit, which analyzes and calculates the measurement data, generates a control command according to a preset control condition, and sends the control command to the actuator of the intake pipe valve or the exhaust pipe valve and the nitrogen generator; The control command includes whether to open or close the air inlet pipe valve, the air outlet pipe valve and the nitrogen generator of a sealed box in a certain storage location.

[0045] The preset control conditions include: determining whether to open or close the nitrogen generator and the air inlet pipe valve and the air outlet pipe valve according to the insecticide days data pre-input for each sealed box.

[0046] If the temperature is between 15-25℃, the nitrogen insecticide time should be controlled at ≥30 days; if the temperature is between 25-35℃, the nitrogen insecticide time should be controlled at ≥25 days. If the temperature is <15℃, insecticide is not recommended.

[0047] Controlling by nitrogen condition control unit can reduce the number of manual switching of nitrogen generators, save labor costs, and timely feedback the concentration data of nitrogen in each sealed box, improve insecticide efficiency, and achieve greater value benefits. Through nitrogen concentration, uniformity, and fluctuation algorithms, nitrogen concentration can be accurately maintained to achieve efficient insecticide effects; and nitrogen insecticide can be intelligent, digital, and unmanned.
