Description

Technical Field

[0001] The present disclosure relates to the field of microwave technology, and in particular to the field of microwave treatment of straw and pest technology. Background Art

[0002] With the development of modern agricultural production, the treatment of straw in farmland and the prevention and control of soil pests and diseases have become increasingly prominent. As a by-product of agricultural production, large amounts of straw not only occupy land, but may also become a breeding ground for pests and diseases. Traditional straw treatment methods, such as incineration, composting, and gasification, all face varying degrees of environmental pollution and low treatment efficiency. However, burning straw not only causes air pollution, but also releases a large amount of greenhouse gases such as carbon dioxide and nitrogen oxides; although composting can effectively degrade straw, the treatment cycle is long and there is a problem of low straw conversion rate; although gasification treatment can reduce emissions, its high cost and technical requirements make it not widely used in most farmlands. On the other hand, the prevention and control of soil pests and diseases has always been an important task in agricultural production. Although traditional chemical pesticides can effectively control pests and diseases in the short term, with the increase in the frequency of use, the emergence of drug-resistant pests and diseases is becoming more and more serious, and the harm of pesticide residues to the environment and human health has attracted more and more attention. Therefore, how to find an environmentally friendly and efficient pest and disease control method is an urgent problem to be solved in the current agricultural field.

Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

Based on the embodiments in the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the embodiments of the present disclosure.

[0038] Microwave technology is a new type of heating technology. The microwave heating principle is to heat the material by making the water molecules or polar molecules in the object vibrate and generate heat. Microwave heating technology can be applied to straw processing and pest control. Microwave technology can quickly penetrate the soil and straw, accurately heat the soil surface or the inside of the straw, and effectively kill the pests and diseases in the soil.

[0039] The present disclosure provides a microwave heating device. Figure 1-7 As shown, including:

[0040] Microwave heating components, excavation components, and processing chambers;

[0041] The digging assembly is used to scoop up the object to be processed and transfer the scooped object to be processed to the processing chamber, wherein the object to be processed includes at least one of straw, soil, and weeds;

[0042] The microwave heating assembly is used to perform microwave heating treatment on the object to be processed in the processing chamber.

[0043] Specifically, the microwave heating assembly includes a magnetron 4-4, a microwave guide tube 4-5, and a microwave stirrer 4-6, wherein the microwave stirrer includes a plurality of fan blades;

[0044] The magnetron 4-4 is used to convert electrical energy into microwave energy and transmit it to the microwave stirrer 4-6 through the microwave guide tube 4-5. The microwave stirrer 4-6 uniformly applies the microwave energy to the object to be processed in the processing chamber through the fan blades. Figure 7 As shown, the microwave stirrer includes 2 blades, and other numbers of blades may be provided according to specific requirements.

[0045] Specifically, the digging assembly includes: a digging shovel 1-2, a plate-type grass-moving roller 2-5;

[0046] The digging shovel 1-2 is used to scoop up the objects to be processed, and the objects are moved and processed by the plate-type grass-pulling roller 2-5 and transferred to the processing chamber.

[0047] The present disclosure provides a microwave heating treatment device, comprising: a microwave heating component, a digging component, and a treatment chamber; the digging component is used to scoop up the object to be treated and transfer the scooped object to be treated to the treatment chamber, and the object to be treated includes at least one of straw, soil, and weeds; the microwave heating component is used to perform microwave heating treatment on the object to be treated in the treatment chamber. That is, the straw, soil, and weeds in the field can be scooped up and transferred to the treatment chamber by the digging component, and then the straw, soil, and weeds in the treatment chamber can be heated by the microwave heating component, thereby achieving the treatment of straw and weeds at the same time, and effectively killing pests and diseases in the soil.

[0048] The disclosed embodiment provides a possible method, wherein the processing chamber includes: two side plates 1-3, a top plate 1-4, a bottom plate 1-5, a front baffle (specifically, the front baffle includes a front movable baffle and a toggle plate; the plate-type grass-moving roller includes a plurality of toggle plates; when the plate-type grass-moving roller rotates, at least one toggle plate of the plate-type grass-moving roller is connected with the front movable baffle), a rear movable baffle (specifically, it may include a movable baffle fixing rod 1-7 and a rear movable baffle 1-8, and the upper end of the rear movable baffle may be movably connected to the top plate 1-4 through the movable baffle fixing rod 1-7), and the two side plates, the top plate, the bottom plate, the front baffle, and the rear movable baffle cooperate to form the processing chamber. That is to say, a relatively closed space can be formed to reduce microwave escape, thereby improving the utilization rate of microwaves.

[0049] Specifically, the processing chamber also includes a string chain conveyor belt, which is used to carry the plate-type grass-moving roller to move the processed objects to the processing chamber, and transport them to the rear end after microwave treatment, and re-enter the farmland through the rear end movable baffle.

[0050] Specifically, the device further includes: a depth-limiting transmission wheel chain 2-3, wherein the depth-limiting transmission wheel chain 2-3 connects the depth-limiting transmission wheel 2-1 and the plate-type grass-pulling roller 2-5, and controls the rotation of the plate-type grass-pulling roller by transmitting power. Thus, the depth-limiting transmission wheel 2-3 and the plate-type grass-pulling roller 2-5 can work in coordination, and as long as the depth-limiting transmission wheel 2-3 is in motion, the plate-type grass-pulling roller 2-5 can be driven to rotate by the depth-limiting transmission wheel chain 2-3.

[0051] Specifically, the device further includes: an excavation depth control component, the excavation depth control component includes a depth-limiting transmission wheel 2-3 and a depth-limiting transmission wheel support arm 2-2; the depth-limiting transmission wheel support arm 2-2 connects the depth-limiting transmission wheel 2-3 and the side plate 1-3 of the processing chamber, and the depth-limiting transmission wheel support arm 2-2 is used to adjust the action height of the depth-limiting transmission wheel by adjusting the horizontal inclination angle of the depth-limiting transmission wheel support arm, thereby controlling the excavation depth of the excavating shovel. Specifically, the horizontal inclination angle of the depth-limiting transmission wheel support arm can be adjusted by first loosening the fixing bolt of the depth-limiting transmission wheel support arm 2-2, adjusting the angle of the depth-limiting transmission wheel support arm 2-2, and then tightening the fixing bolt, and the toothed washer fixes the position of the support arm through the gearing action. Through this process, the working height of the depth-limiting transmission wheel 2-3 can be accurately adjusted, thereby controlling the burial depth of the excavating shovel. When the horizontal angle of the support arm decreases, the working height of the depth-limiting transmission wheel will be raised, and the burial depth of the excavating shovel will increase; when the angle is increased, the depth-limiting transmission wheel will be lowered, and the burial depth of the excavating shovel will decrease. This makes it possible to apply microwave treatment to land at different operating depths.

[0052] The disclosed embodiment provides a possible implementation method, wherein a multispectral sensor is configured at the top of the processing chamber (specifically, it may be located near the microwave agitator, with a field of view covering the object to be processed on the conveyor belt), and the multispectral sensor is used to collect spectral data of the object to be processed in the processing chamber in different spectral bands; the device also includes a data processing module, which is used to determine the moisture content, composition ratio and density of the object to be processed according to the collected spectral data, and adjust the heating power and processing speed of the microwave heater according to the determined moisture content, composition ratio and density of the object to be processed, thereby improving the uniformity and efficiency of the processing effect. Among them, the introduction of the multispectral sensor realizes dynamic monitoring and intelligent regulation of the material state, so that the equipment can more efficiently and accurately complete the dual processing goals of straw and soil. .

[0053] For example, Figure 1-7 As shown, the working principle and process of the microwave processing device can be:

[0054] 1. Tractor traction and power input

[0055] The device (microwave heating device) can be connected to the tractor through the suspension device 1-1 of the device (microwave heating device), and can stably follow the traction of the tractor when the device is working. The tractor rear power output shaft is connected to the gearbox 4-3 of the device, and the gearbox 4-3 serves as a power transmission device to distribute power to multiple system components. Specifically, the gearbox not only provides power for the generator 4-2, but also drives the operation of the string chain conveyor belt 3-7 and the depth-limiting transmission system through power transmission.

[0056] Specifically, the gearbox drives the chain conveyor belt 3-7 through the chain conveyor belt power input shaft (3-3), the chain conveyor belt power input sprocket (3-6) and the chain conveyor belt power input chain (3-5), so that the chain conveyor belt 3-7 can transport the scooped straw, weeds and soil to the rear end of the processing chamber along the cavity. The gearbox (3-2) can provide power to the generator through the generator power input shaft (4-1), and the generator converts mechanical energy into electrical energy, adjusts the voltage through the transformer (4-3), and provides stable power support for the magnetron (4-4).

[0057] The depth-limiting driving wheel (2-1) drives the depth-limiting driving wheel chain (2-3) by friction with the ground, thereby providing power for the plate-type weed-pulling roller (2-5) to rotate, thereby driving the metal plate (pulling plate) on the weed-pulling roller to pull the scooped straw, weeds and soil into the processing chamber of the equipment.

[0058] 2. Collaboration between the depth-limiting drive system and the excavating shovel

[0059] The depth-limiting transmission system adjusts the position of the depth-limiting transmission wheel 2-1 to control the depth of the digging shovel, ensuring that the equipment can accurately shovel up straw and shallow soil. The power generated by the friction between the depth-limiting transmission wheel and the ground can further drive the plate-type grass-pulling roller 2-5 to rotate.

[0060] Among them, the depth-limiting transmission system mainly includes components such as the depth-limiting transmission wheel 2-1, the depth-limiting transmission wheel support arm 2-2 and the adjustment mechanism. The adjustment mechanism limits the angle change of the support arm 2-2 through the toothed washer to ensure that the depth-limiting transmission wheel support arm 2-2 remains stable during the adjustment process. Specifically, the horizontal tilt angle of the depth-limiting transmission wheel support arm can be adjusted by first loosening the fixing bolts of the depth-limiting transmission wheel support arm 2-2, adjusting the angle of the depth-limiting transmission wheel support arm 2-2, and then tightening the fixing bolts. The toothed washer fixes the position of the support arm through the gearing action. Through this process, the working height of the depth-limiting transmission wheel 2-3 can be accurately adjusted, thereby controlling the depth of the excavating shovel into the soil. When the horizontal angle of the support arm decreases, the depth-limiting transmission wheel will raise its working height, and the depth of the excavating shovel into the soil will increase; when the angle is increased, the depth-limiting transmission wheel will be lowered, and the depth of the excavating shovel into the soil will decrease.

[0061] 3. Delivery and transportation of straw and soil

[0062] Under the traction of the tractor, the digging shovel enters the soil and scoops up the straw and shallow soil. As the tractor moves forward, the depth-limiting drive wheel continues to rotate, providing power to the plate-type weed-pulling roller to rotate. The metal plate (pulling plate) on the plate-type weed-pulling roller pulls the scooped straw, weeds, and soil into the processing chamber of the equipment.

[0063] The front end of the processing chamber is closed by the metal plate (moving plate) on the weeding roller and the metal soft plate 1-6 on the crossbeam, and the rear end is enclosed by the movable baffle 1-7, two side plates 1-3, the top plate 1-4 and the bottom plate 1-5. This can reduce microwave escape and improve microwave utilization.

[0064] 4. Microwave heating and pest control

[0065] The magnetron 4-4 starts to generate microwaves under the power drive, and the microwaves are transmitted to the microwave stirrer 4-6 through the microwave guide tube 4-5. The microwave stirrer 4-6 evenly distributes the microwaves through the metal fan blades, so that the microwave energy can evenly heat the straw and soil in the cavity. The microwave energy heats the materials in the cavity, which can not only effectively kill the pests and diseases in the soil, but also accelerate the decomposition of the straw and reduce the difficulty of straw processing.

[0066] 5. Treatment and discharge of straw and soil

[0067] The straw and soil after microwave heating are transported to the rear end through a string-rod chain conveyor belt and re-enter the farmland, completing the dual treatment process of farmland straw and pests and diseases.
