Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of methanol burner, in particular to a towed methanol combustion device system for agricultural field treatment. BACKGROUND

[0002] In agricultural production, it is necessary to remove weeds or process straw in the field. Traditional methods of weed removal, straw processing and insect egg killing in the field mostly rely on manual weeding, chemical spraying or direct burning. There are also some fuel oil type or fixed power driven flame treatment equipment. These equipment usually uses traditional fuel such as diesel to produce high temperature flame for processing the target in the field.

[0003] These fossil fuels such as diesel not only have high operating cost, but also produce a large amount of sulfide and particulate matter after combustion, which pollutes the operation area and the surrounding environment, and does not meet the development trend of green agriculture. Secondly, the equipment driven by fixed power has poor mobility, and the mobile equipment using small engines often has limited power and low processing efficiency, which is difficult to meet the needs of large-scale field operation. Furthermore, the structure of the existing combustion equipment is often fixed and cannot be flexibly adapted to mainstream agricultural machinery platforms such as tractors, and the deployment width is limited, resulting in small single operation area and low efficiency. In addition, the maintenance of the equipment is often complex, and the non-modular design makes fault diagnosis and component replacement time-consuming and laborious, increasing the downtime and use cost of the user.

[0004] Therefore, in view of the above problems, the present application provides a towed methanol combustion device system for agricultural field treatment. SUMMARY

[0005] In order to overcome the problems of serious environmental pollution, low operation efficiency, poor adaptability and mobility to agricultural machines and inconvenient maintenance of existing field treatment equipment, the present application provides a towed methanol combustion device system for agricultural field treatment.

[0006] The technical scheme of the present application is: a towed methanol combustion device system for agricultural field treatment, comprising a main frame and a sub-frame, characterized in that it comprises: a generator and an oil tank mounted on the main frame, a main wheel mounted on the side of the main frame, an electric box fixed to the main frame, a mounting bracket welded to the electric box, an oil pump welded to the mounting bracket, a movable frame rotatably connected to the main frame or the sub-frame, a fan mounted on the movable frame, a main hydraulic cylinder rotatably connected to the main frame and the sub-frame, a sub-hydraulic cylinder rotatably connected to the sub-frame and the movable frame, a fire grate fixed to the movable frame, a vertical rod mounted on the side of the main frame, and a ground wheel arranged at the lower end of the vertical rod. Among them, the electric box is provided with three, and the fan and the fire row on each movable frame are independently controlled through an electric box. Methanol fuel is transported to the fire row through the control of the oil pump, and the fire row is ignited through the controller. The fan is started to spray fire and burn. This design of independent control of each part allows the system to work locally or start in sections, improving the flexibility of operation and energy utilization efficiency.

[0007] Preferably, the main hydraulic cylinder is used to control the unfolding and folding of the secondary frame, and the secondary hydraulic cylinder is used to drive the movable frame to rotate relative to the secondary frame, so as to accurately adjust the working angle and height of the fire row.

[0008] As preferred, the main frame comprises a frame, a first support rod welded on the frame, a third support rod welded on the first support rod, and a second support rod fixedly connected with the first support rod and the third support rod.

[0009] As preferred, the movable frame comprises a mounting plate rotatably connected to the main frame or the secondary frame, and a mounting bracket welded on the mounting plate. The fan is fixedly connected to the mounting plate, and the fire row is welded on the side of the mounting plate. The mounting bracket provides a stable mounting base for the fan and ensures that the air outlet direction of the fan is coordinated with the flame spraying direction of the fire row, so as to optimize the shape and spraying distance of the flame.

[0010] As preferred, the fire row comprises a connecting rod welded on one side of the mounting plate, a spray head arranged on one side of the connecting rod, a methanol electromagnetic valve fixedly connected to the other side of the connecting rod, a fire row connecting bracket welded on the connecting rod, a plurality of fourth support rods welded on the fire row connecting bracket, a fire plate rotatably connected to the fourth support rods, and a chain connected to the fourth support rods and the fire plate. By lowering the fire plate to be parallel, the chain supports the fire plate at this time, and the methanol electromagnetic valve ignites and sprays methanol from the spray head.

[0011] As preferred, the spray head and the methanol electromagnetic valve are each provided with 54, and each group is provided with 18.

[0012] As preferred, the fourth support rod and the fire plate are each provided with 27, and each group is provided with 9.

[0013] As preferred, the frame can be mounted on a tractor or other multifunctional agricultural machinery platform through a three-point hitch structure, realizing flexible networking and traction operation.

[0014] As preferred, the fire row parts on both sides of the system are designed to be detachable. When installing or reusing, they need to be aligned with the recess or clamping position of the vehicle body for assembly and fixation by a crane or forklift, and the corresponding control cable and high-voltage ignition cable are connected to the high-voltage pack and relay in the electric cabinet.

[0015] Preferably, the ignition and control of the system specifically includes: the operator uses a first remote control to start the first group of burners, and after a successful start, after an interval of about 10 seconds, uses a second remote control to start the second group of burners, and so on, to open multiple groups of burners in sequence. During this process, the corresponding methanol solenoid valve opens to supply fuel, the high-pressure coil generates an ignition spark, and then the corresponding blower starts with a delay.

[0016] The beneficial effects of this invention are: 1. This invention uses methanol as the main fuel. Compared with traditional fossil fuels such as diesel, it burns more cleanly and can significantly reduce the emission of pollutants such as sulfides and particulate matter, which meets the requirements of green and environmentally friendly modern agricultural development. Moreover, it uses its own methanol generator set to generate electricity, achieving energy self-sufficiency and greatly improving the mobility and adaptability of the equipment in field operations.

[0017] 2. By adopting a three-point hook structure for quick connection with mainstream agricultural machinery such as tractors, and combining a hydraulically driven subframe and movable frame design, the system can quickly obtain a wide working width (such as about 9 meters) to efficiently handle large fields, and can also be folded up when not in operation for easy relocation and transportation, effectively solving the contradiction between poor mobility and low operating efficiency of traditional equipment.

[0018] 3. The system is equipped with nozzles distributed over a width of approximately 1 meter. With an operating speed of approximately 1 km / h, it can efficiently process more than 100 acres of land per hour, greatly improving the efficiency of weed removal, straw processing, and other operations, and meeting the urgent needs of modern field agriculture for high-efficiency operations.

[0019] 4. By using three electrical boxes to independently control the system in different zones, and combining this with a remote control strategy of sequential interval ignition (e.g., interval of seconds), the instantaneous high current surge caused by the simultaneous start-up of multiple burners on the generator set is effectively avoided, ensuring the smoothness and reliability of the system startup, while also enabling flexible control of different work areas.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-6 The present invention provides an embodiment: a trailer-mounted methanol combustion device system for agricultural field treatment. This system is supported by a main frame and two auxiliary frames. The main frame serves as the foundation for the entire system, and the generator 2 and fuel tank 3 are integrated on it. The front of the main frame is quickly connected to agricultural power machinery such as tractors via a three-point hook structure, while the rear is connected to the side frame 8, i.e., the auxiliary frame, via a hinge. The two ends of the main hydraulic cylinder 11 are respectively hinged to the main frame and the side frame 8. Through its telescopic movement, the side frame 8 is driven to unfold or fold relative to the main frame, thereby changing the width of the entire system. In the transport state, the side frame 8 can be folded up, and the system width is about 3 meters. In the operation state, the side frame 8 is unfolded, and the total system width can reach about 9 meters.

[0024] On the main frame and each side frame 8, a movable frame is rotatably connected. The movable frame mainly includes a mounting plate 15 and a mounting bracket 16. An auxiliary hydraulic cylinder 18 is connected between the side frame 8 and the mounting plate 15 to adjust the pitch angle of the movable frame, thereby precisely controlling the distance and angle between the flame and the ground. The fire bar 20 and the fan 17 are directly fixed to the mounting plate 15 to form a complete combustion execution unit.

[0025] In this embodiment, the power source comes from an M20000 methanol generator set 2 with a rated power of 18kW. It uses M100 refined alcohol and anhydrous methanol as fuel. The generator set 2 is the power source for all electrical equipment in this system, including oil pump 3, methanol solenoid valve 21, fan 17 and control system, providing 380V / 220V AC power, realizing complete energy self-sufficiency in the operation process.

[0026] Fuel is stored in a 2000-liter stainless steel fuel tank 3 with a fuel meter. The fuel supply is handled by a set of parallel pumps, mainly including 1600W methanol oil pumps 3, which are responsible for pumping methanol out of the fuel tank 3 and establishing a stable pressure to deliver it to the methanol solenoid valves 21 distributed on each burner 20.

[0027] In this embodiment, the system is equipped with three independent electrical boxes 12, which control the left, middle, and right combustion units respectively, achieving independent zone control. Each electrical box 12 integrates corresponding relays and high-voltage transformers, among other electrical components. The ignition process adopts a sequential interval start-up strategy. The operator uses three independent remote controls to sequentially control the start-up of the three burner groups. The specific process is as follows: 1. Operate the first remote control to turn on the first group, such as the left burner. At this time, the corresponding oil pump 3 starts to supply oil, and 220V methanol ignites the high-voltage pack 4 to generate a high-voltage arc for ignition.

[0028] 2. After successful ignition, after an interval of about 3 seconds, the corresponding 1.6KW high-temperature resistant fan 17 starts with a delay, blowing the flame out of the flame exhaust port to form a stable jet flame.

[0029] 3. After a 3-second interval, operate the second remote control to start the second group, such as the middle burner, using the same procedure.

[0030] 4. After a pause of approximately 3 seconds, operate the third remote control to activate the third group of components, such as the right-side burner. This sequential start-up method effectively avoids the huge instantaneous current surge to generator 2 caused by the simultaneous start-up of all high-power electrical appliances, especially the fan, thereby greatly improving the reliability of system startup and the lifespan of the generator set.

[0031] Please see Figure 6 In this embodiment, the fire baffle of the present invention includes a connecting rod 19, a nozzle 20, a methanol solenoid valve 21, a fire baffle connecting frame 22, a fourth support rod 23, a fire suppressor plate 24, and a chain 25. The fire suppressor plate 24 is connected to the fourth support rod 23 via a hinge, and the chain 25 connects the free ends of the fourth support rod 23 and the fire suppressor plate 24. During operation, the fire suppressor plate 24 is lowered to a near-horizontal position. At this time, the chain 25 is straightened, forming a stable triangular support, fixing the fire suppressor plate 24 at this angle. This fire suppressor plate 24, located under the flame, serves to concentrate and suppress the flame.

[0032] This invention provides Embodiment 1: This embodiment describes the treatment process conducted on a large farm in fields after corn harvest. In this scenario, there are a large amount of residual corn stalks in the fields. The treatment objectives are twofold: first, to quickly and efficiently remove these stalks; and second, to kill insect eggs and weed seeds on the soil surface through high-temperature incineration and to utilize the resulting ash to enhance soil fertility, such as potassium content.

[0033] Before the operation begins, the tractor pulls the system to the designated field operation area using a three-point hook structure.

[0034] After preparation, the tractor's hydraulic output function is activated to drive the main hydraulic cylinder 11 connected between the main frame and the side frame 8 to slowly extend, thereby unfolding the side frames 8 from their folded position in the transport state to a horizontal working position, making the entire system width approximately 9 meters. Then, the operator drives the auxiliary hydraulic cylinder 18 connected between the side frame 8 and the movable frame to adjust the pitch angle of the movable frame, which is equipped with the fire vent 20 and the blower 17. Finally, the nozzle of the fire vent 20 is adjusted to the ideal height of 30-50 centimeters above the ground. Finally, the pressure plate 24, which is hinged to the fourth support rod 23 on each fire vent unit, is lowered to a near-horizontal position, and its free end is connected to the support rod using the chain 25 to straighten it, forming a stable triangular support structure to fix the working angle of the pressure plate 24.

[0035] After the system is deployed and adjusted, it enters the ignition and operation phase. First, turn on the power switch of generator 2, and the generator set will start automatically. After it runs smoothly, close the overload protector switch to supply power to the entire combustion system. The operator holds three independent remote controls in a safe upwind position. First, press the button on remote control 1 to start the left burner group. At this time, the methanol solenoid valve 21 corresponding to this group opens to supply fuel, and the high-voltage coil 4 generates an ignition arc at the same time. After observing and confirming that the flame is stably ejected, about 3 seconds later, the 1.6KW high-temperature resistant high-speed fan 17 corresponding to this group starts with a delay to blow out the flame. After a 3-second interval, the operator presses the button on remote control 2 to start the middle burner group in the same process. After another 3-second interval, press the button on remote control 3 to start the right burner group. At this point, the entire burner group, which is about 9 meters long, produces a stable jet of flame. Then, the tractor is engaged and moves forward at a constant speed of about 10 km / h. A wide, continuous and high-temperature flame band is formed behind the system, which thoroughly burns the straw in the area it passes through.

[0036] During operation, the sprayed flames burn close to the ground, ensuring that all residues, including the roots of the straw, are fully burned. This also concentrates the heat on the soil surface, achieving the goal of efficiently killing insect eggs and weed seeds. At the same time, the ash produced after burning the straw can be evenly covered on the field surface, effectively improving the soil's fertility, such as potassium. With its ultra-wide operating width of about 9 meters and a travel speed of about 10 kilometers per hour, this system achieves an extremely high efficiency of more than 100 acres per hour in this embodiment.

[0037] After the field straw burning operation is completed, the operator first operates the three remote controls in sequence to shut down the left, middle and right fire bars to stop the burning process. Then, the power supply of the methanol generator set 2 is turned off to cut off the power supply of the entire system. After the system cools down to a safe temperature, the operator needs to retract the fire plate 24 to the non-working state and drive the main hydraulic cylinder 11 to fold the side frames 8 on both sides back to one side of the main frame to reduce the transport width. Finally, the entire system is pulled away from the work site by a tractor.

[0038] This invention provides Embodiment 2: This embodiment involves clearing weeds between rows in an orchard where fruit trees are planted in rows and a large number of stubborn weeds grow between the rows. The goal of the treatment is to clear the weeds between the fruit tree rows without damaging the fruit trees and without using chemical herbicides.

[0039] Given the limited working space between rows in orchards, operators do not need to fully extend the entire system. Instead, they can choose to extend only one side of the side frame 8 and its movable frame, or even not extend the side frame at all, and only use the intermediate fire bar assembly installed on the main frame. By controlling the extension and retraction of the auxiliary hydraulic cylinder 18 connected between the side frame 8 and the movable frame, the pitch angle and horizontal position of the movable frame and its fire bar 20 can be precisely adjusted, so that the flame nozzle can be accurately aimed at the weed area between the fruit tree rows, while ensuring that the flame maintains a safe distance from the fruit tree trunk and root system to avoid heat damage.

[0040] Operators can selectively ignite the required fire rows by controlling the corresponding electrical box 12, such as activating only the left or middle fire row group, without activating all three fire rows. This precise energy delivery mode enables energy-saving operation and perfectly adapts to irregular field layouts. The ignition process also adopts a safe and reliable remote-controlled sequential start method. The operator remotely starts the required fire rows in sequence from a safe position, with an interval of about 3 seconds between each start, ensuring the stability of the power supply system. Then, the tractor moves at a low speed along the rows of fruit trees to carry out directional flame weeding operations.

[0041] During the operation, the high-temperature flame instantly burns the weed plants, causing their cell walls to rupture and leading to rapid dehydration and death. This physical weeding method completely avoids the soil pollution and pesticide residue problems that may be caused by chemical herbicides, making it very environmentally friendly. For perennial deep-rooted weeds, the high temperature of the flame can also effectively destroy the physiological activity of their underground parts. The system's flexible modular control and adjustable flame spray mechanism enable it to adapt to various complex orchard environments, achieving precise weed removal while perfectly protecting the safety of economic crops and fruit trees.

[0042] After each operation, this invention requires checking all pipe interfaces for leaks and cleaning any carbon black or impurities that may be adhering to the surface of the flame arrester nozzle 20. The generator 2 must strictly adhere to the regulation of changing the methanol engine oil every 100 hours of operation. Approximately every three months or after a cumulative 500 hours of operation, it is recommended to disassemble the flame arrester 20 and clean the internal channels of the nozzle 20 with a special cleaning agent to prevent trace impurities in the methanol from clogging the nozzles. The hydraulic system requires regular checks of the hydraulic oil level and the hydraulic cylinder's sealing. If the system is to be parked for an extended period, the generator 2's starting battery must be periodically charged and discharged to prevent battery depletion and damage. If ignition failure or unstable flame occurs, first check whether the wiring of the corresponding zone is secure, whether the oil line interfaces are leaking, and whether the high-voltage coil ignition arc is normal. The modular design makes troubleshooting and component replacement very convenient.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
