Description

Technical Field

[0001] This utility model relates to the field of tobacco soil purification technology, and in particular to a device for degrading herbicide residues in tobacco soil using carbon-based materials. Background Technology

[0002] With the development of modern agriculture, herbicides are widely used in tobacco cultivation to effectively control weed growth and improve tobacco yield and quality. However, the extensive use of herbicides has led to serious soil residue problems. These herbicide residues not only negatively impact tobacco growth and development but may also pose a potential threat to human health through the food chain.

[0003] Traditional methods for removing herbicide residues from soil have many limitations. Physical methods, such as deep tillage, can dilute the concentration of herbicides in the soil to some extent, but they are costly and can easily damage the soil structure. Chemical methods may introduce new chemical substances, causing secondary pollution. Although biodegradation is relatively environmentally friendly, its degradation efficiency is often greatly affected by environmental factors, and the adaptability and activity of microorganisms are difficult to control effectively, resulting in an unstable degradation process that takes a long time. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a device for degrading herbicide residues in tobacco-growing soil using carbon-based materials. This solves the technical problem that existing technologies cannot stably and safely purify herbicide residues in tobacco-growing soil, achieving the goal of stably and safely degrading herbicide residues.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a device for degrading herbicide residues in tobacco-growing soil using carbon-based materials, including a connecting frame installed on the top of a rotary tiller, the rotary tiller being equipped with a degradation mechanism for discharging carbon-based materials into the tobacco-growing soil, and the rotary tiller being equipped with a film-covering mechanism for covering and controlling the temperature of the tobacco-growing soil.

[0006] The degradation mechanism includes a liquid storage tank installed on the top of the rotary tiller, and a drain pipe that penetrates the top of the rotary tiller is installed at the bottom of the liquid storage tank. A booster pump is installed on the drain pipe, and a sprayer is installed at the bottom of the drain pipe. A mixing component for placing the carbon-based material raw liquid precipitate is provided in the liquid storage tank.

[0007] A further improvement is that the mixing assembly includes multiple rotating shafts rotatably connected to a rotating hole opened at the top of the liquid storage tank, and multiple sets of mixing rods are vertically and equidistantly installed on the rotating shafts. A pulley is installed at the top of the rotating shaft, and a transmission belt is connected between two adjacent pulleys. A drive motor for driving the pulleys to rotate is installed on the liquid storage tank.

[0008] A further improvement is that an injection pipe is installed on the top of the liquid storage tank, and an observation window is installed on the side of the liquid storage tank.

[0009] A further improvement is that the film covering mechanism includes crossbeams installed at both ends of the rotary tiller, and a feeding roller is rotatably connected in the rotating holes opened on the crossbeams. An electric lifting rod is installed on the crossbeams, and a bearing is installed at the free end of the bottom of the electric lifting rod, and a film covering roller is rotatably connected in the bearing. A soil covering plow for covering the film is installed at the bottom of both ends of the rotary tiller, and a perforating assembly for perforating the film for ventilation is provided on the crossbeams.

[0010] A further improvement is that the punching assembly includes a rotating shaft rotatably connected to a rotating hole in the crossbeam, with a half gear installed at the inner end of the rotating shaft, a cross plate installed between the two crossbeams, and a rack that meshes with the half gear slidingly connected to a groove in the cross plate, with a locking block installed on the side of the rack, an installation plate installed between the two racks, and punching rods arranged in an array on the installation plate.

[0011] A further improvement is that pulleys are also installed at both ends of the feeding roller and the outer end of the rotating shaft, and the two corresponding pulleys on the same side of the feeding roller and the rotating shaft are connected by a transmission belt.

[0012] By employing the above technical solution, this utility model provides a device for degrading herbicide residues in tobacco-growing soil using carbon-based materials, which has at least the following beneficial effects:

[0013] 1. This utility model uses a booster pump to inject the carbon-based material raw liquid in the storage tank into the sprayer through the drain pipe and spray it into the tobacco planting soil, thereby utilizing the carbon-based material to fully degrade and purify the herbicide residues in the tobacco planting soil.

[0014] 2. This utility model uses the movement of a rotary tiller to drive the film roll on the feeding roller to rotate and feed the material. At this time, the electric lifting rod is activated to push the film covering roller in the bearing at the bottom of the roller to move down and press the film onto the field. The covering plow rolls up the soil after tilling and covers both sides of the film, thereby completing the film covering and heat preservation.

[0015] 3. This utility model uses a feeding roller to drive a rotating shaft to rotate, which in turn drives a half gear to rotate and lift the rack until the two disengage. At this time, the rack falls under the action of gravity, which drives the punching rod to fall and punch holes in the film, thereby realizing soil ventilation and avoiding excessive soil temperature.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Addressing the problem that current technologies cannot reliably and safely purify herbicide residues in tobacco-growing soil, this embodiment provides a device for degrading herbicide residues in tobacco-growing soil using carbon-based materials. Please refer to... Figures 1-5 This embodiment provides a device for degrading herbicide residues in tobacco-growing soil using carbon-based materials, which can stably and safely degrade herbicide residues. The device includes a connecting frame 2 installed on top of a rotary tiller 1, a degradation mechanism 3 on the rotary tiller 1 for discharging carbon-based materials into the tobacco-growing soil, and a covering mechanism 4 on the rotary tiller 1 for covering and temperature-controlled tobacco-growing soil. The degradation mechanism 3 discharges liquid carbon-based materials into the tobacco-growing soil after it has been tilled by the rotary tiller 1, allowing the carbon-based materials to degrade and purify the herbicide residues. When the temperature is low, the covering mechanism 4 covers the soil, allowing the carbon-based materials to degrade the herbicide residues at a temperature between 25°C and 40°C.

[0032] Since existing technologies cannot reliably and safely purify herbicide residues in tobacco-growing soil, this device is equipped with a degradation mechanism 3. The degradation mechanism 3 includes a liquid storage tank 31 installed on the top of the rotary tiller 1, and a drain pipe 32 penetrating the top of the rotary tiller 1 is installed at the bottom of the liquid storage tank 31. A booster pump 33 is installed on the drain pipe 32, and a sprayer 34 is installed at the bottom of the drain pipe 32. A mixing component 35 for placing carbon-based material raw liquid precipitate is installed in the liquid storage tank 31. When the rotary tiller 1 tills the tobacco-growing soil, the booster pump 33 is activated to inject the carbon-based material raw liquid in the liquid storage tank 31 into the sprayer 34 through the drain pipe 32 and spray it into the tobacco-growing soil. The carbon-based material is used to fully degrade and purify the herbicide residues in the tobacco-growing soil.

[0033] Since carbon-based materials are prone to sedimentation when stationary, which can lead to uneven spraying, the device also includes a mixing component 35. The mixing component 35 includes multiple rotating shafts 351 rotatably connected to a rotating hole at the top of the storage tank 31. Multiple mixing rods 352 are vertically and equidistantly mounted on the rotating shafts 351. A pulley 353 is mounted on the top of the rotating shaft 351, and a transmission belt 354 is connected between adjacent pulleys 353. A drive motor 355 is mounted on the storage tank 31 to drive the pulleys 353 to rotate. When the drive motor 355 is started, it drives the pulleys 353 to rotate, and through the transmission belts 354 connected to each other in the pulleys 353, it drives the rotating shafts 351 to rotate, which in turn drives the mixing rods 352 on the rotating shafts 351 to rotate and stir the carbon-based material liquid in the storage tank 31, thus preventing sedimentation and blockage of the drain pipe.

[0034] A liquid injection pipe 36 is installed on the top of the liquid storage tank 31, and an observation window 37 is installed on the side of the liquid storage tank 31. The remaining amount of carbon-based material raw liquid in the liquid storage tank 31 can be observed in real time through the observation window 37, and liquid can be replenished in time through the liquid injection pipe 36.

[0035] Since carbon-based materials require a temperature between 25°C and 40°C to effectively degrade and purify herbicides in tobacco-growing soil, a film-covering mechanism 4 is installed in the device to maintain soil temperature during the cold winter months. The film-covering mechanism 4 includes crossbeams 41 installed at both ends of the rotary tiller 1, with a feeding roller 42 rotatably connected to a rotating hole on the crossbeams 41. An electric lifting rod 43 is installed on the crossbeams 41, and a bearing 44 is installed at the free end of the bottom of the electric lifting rod 43. A film-covering roller 45 is rotatably connected to the bearing 44. The bottom of both ends of the rotary tiller 1 is equipped with a film-covering mechanism for... The covering plow 46 has a perforation assembly 47 on its crossbeam 41 for perforating the film to allow for ventilation. The rolled film is placed on the feeding roller 42, with one end of the film buried in the soil. The rotary tiller 1 is connected to the tractor via the connecting frame 2. As the rotary tiller 1 moves, it drives the feeding roller 42 to rotate in the rotating hole on the crossbeam 41, thereby driving the film roll to rotate and feed the film. At this time, the electric lifting rod 43 is activated, pushing the covering roller 45 in the bearing 44 at its bottom to move down and press the film onto the field. The covering plow 46 rolls up the plowed soil and covers both sides of the film, thus completing the covering and heat preservation.

[0036] Example 2

[0037] Based on Example 1, such as Figures 1-5 As shown, in order to maintain ventilation and avoid excessive temperature inside the completely sealed film, the device is also provided with a perforation assembly 47. The perforation assembly 47 includes a rotating shaft 471 rotatably connected to a rotating hole opened on the crossbeam 41, and a half gear 472 is installed at the inner end of the rotating shaft 471. A cross plate 473 is installed between the two crossbeams 41, and a rack 474 that is slidably connected to the half gear 472 in a groove opened on the cross plate 473. A locking block 475 is installed on the side of the rack 474, and a mounting plate 476 is installed between the two racks 474. Perforation rods 477 are arrayed on the mounting plate 476.

[0038] Both ends of the feeding roller 42 and the outer end of the rotating shaft 471 are also equipped with pulleys 353. The two corresponding pulleys 353 on the same side of the feeding roller 42 and the rotating shaft 471 are connected by a transmission belt 354. As the feeding roller 42 rotates, it drives the pulleys 353 on it to rotate, and drives the rotating shaft 471 to rotate through the transmission belt 354. This drives the half gear 472 to rotate, lifting the rack 474 that is meshed with it until the two disengage. At this time, the rack 474 falls under the action of gravity, and the mounting plate 476 on the rack 474 falls synchronously. The perforation rod 477 at the bottom of the mounting plate 476 perforates the film, thereby realizing the ventilation of the soil and preventing the soil temperature from becoming too high.
