[0001] The utility model relates to the field of agricultural machinery, in particular to a self-generating soil remediation device with an air heat source. Background technology

[0002] According to current technology, in order to increase arable land resources and improve land use, it is sometimes necessary to reclaim land. In land reclamation, the commonly used equipment is the rotary tiller, but the rotary tiller can only crush and plow the soil, because some soils often contain straw, grass seeds, insect eggs, heavy metal eggs, pesticide residues and other pollutants, and these pollutants cannot be removed by rotary tiller alone. A commonly used method is fire. The removal of these pollutants is achieved by setting fire to land. However, this burning method is very dangerous and easily leads to air pollution, so it needs to be improved. Content of the utility model

[0003] The utility model is designed to solve at least one of the technical problems existing in the prior art. Therefore, one object of the utility model is to provide a self-generating soil remediation device with an air heat source to solve the limitations of the prior art using rotary tillers and combustion methods for soil remediation.

The gear assembly is connected to the rotary cutter main shaft. The rotary cutter main shaft is provided with a plurality of rotary cutter tooth blades arranged at intervals along the longitudinal direction of the rotary cutter main shaft.

[0005] A power generation assembly. The power generation assembly consists of a generator set and a transmission mechanism. The generator set is mounted on the frame. The input end of the generator set is connected to the rotary tiller's main shaft via the transmission mechanism.

[0006] An air heat spray assembly. The air heat spray assembly consists of an air compressor, a high-pressure air heater, and an ejector.

The air compressor, the high-pressure air heater, and the ejector are all arranged on the frame. The air compressor is connected to the high-pressure air heater. The high-pressure air heater is connected to the ejector. The ejector is located in front of the rotary tiller's main shaft. There are multiple ejectors arranged at intervals along the longitudinal direction of the rotary tiller's main shaft.

[0007] In addition, the transmission mechanism is a gear transmission with clutch.

[0008] In addition, the high pressure air heater is used to heat the air to 300-750 °C.

[0018] A self-generating soil remediation device with air heat source, as in the Fig. shown, includes: a rotary cutter body, a power generation assembly, and an air heat spray assembly.

[0019] The rotary tiller body consists of a frame 1, a suspension frame 2, a gear assembly 3, a rotary tiller main shaft 4, and a rotary tiller toothed blade 5. The frame 1 is provided with the suspension frame 2, the gear assembly 3, and the rotary tiller main shaft 4. The rotary tiller main shaft 4 is rotatably connected to the frame 1. The gear assembly 3 is connected to the rotary tiller main shaft 4. The rotary tiller main shaft 4 is provided with a plurality of rotary tiller toothed blades 5 arranged at intervals along the longitudinal direction of the rotary tiller main shaft 4.

[0020] In certain applications, the rotary tiller body is typically used in conjunction with a tractor. The suspension frame 2 is connected to the tractor, allowing the tractor to pull and move the entire unit through the suspension frame 2. The transmission assembly 3 utilizes the tractor's power to drive the rotary tiller main shaft 4, thereby rotating the rotary tiller toothed blade 5, which breaks up and cultivates the soil.

[0021] In the prior art, the transmission assembly 3 of a rotary tiller generally consists of a gearbox located in the center of the frame 1 and a lateral or central gearbox. The gearbox is made entirely of gray cast iron and contains transmission gears. Power is transmitted in the gearbox from the tractor's PTO or pulley via a universal joint or V-belt. If it is an intermediate gearbox, the intermediate gear of the gearbox meshes directly with the gear of the rotary tiller's main shaft 4 to drive the rotary tiller's main shaft 4. If it is a lateral gearbox, it must also be passed through the lateral gear housing or sprocket housing to drive the rotary tiller's main shaft 4.The rotary tiller is usually also equipped with a hydraulic lifting mechanism connected to the frame 1 so that the hydraulic lifting mechanism can automatically raise and lower the frame 1.

[0022] To improve the efficiency of the rotary tiller, a two-axis rotary tiller can also be selected as needed, which includes two front and rear rotary tiller main shafts 4, and a rotary tiller toothed blade 5 is attached to each rotary tiller main shaft 4. This solution does not limit the type of rotary harrow selected.

[0023] The above is a brief introduction to the main structure and transmission principle of the rotary milling machine body. Since it is prior art and well known to those skilled in the art, it will not be repeated here.

[0024] This solution mainly adds a power generation assembly and an air heat spray assembly to the structure of the existing rotary tiller. The power generation assembly consists of a generator set 7 and a transmission mechanism 8. The generator set 7 is arranged on the frame 1. The input end of the generator set 1 is connected to the rotary tiller main shaft 4 via the transmission mechanism 8. The air heat spray assembly consists of an air compressor 9, a high-pressure air heater 10, and an ejector 11. The output end of the generator set 7 is connected to the air compressor 9 and the high-pressure air heater 10. The air compressor 9, the high-pressure air heater 10, and the ejector 11 are all arranged on the frame 1. The air compressor 9 is connected to the high-pressure air heater 10. The high-pressure air heater 10 is connected to the ejector 11. The ejector 11 is located in front of the rotary milling machine main shaft 4.There are a plurality of ejectors 11 arranged at intervals along the longitudinal direction of the rotary milling main shaft 4.

[0025] In particular, as in Fig. As shown, the arranged power generation assembly mainly utilizes the rotating kinetic energy of the rotary tiller main shaft 4 to generate power, thereby supplying power to electrical components such as the air compressor 9 and the high-pressure air heater 10, making this device suitable for field use, which is impractical for outdoor power supply. In this solution, the transmission mechanism 8 is arranged on the side of the frame 1. The transmission mechanism 8 is a gear transmission with a clutch. One end of the rotary tiller main shaft 4 is extended outward so that it can be connected to the input end of the gear transmission. The output end of the gear transmission is connected to the input end of the generator set 7. Therefore, when the rotary tiller main shaft 4 rotates, the generator set 7 can be driven by the transmission mechanism 8 to generate power.In addition, the transmission mechanism 8 of this solution is a gearbox with a clutch, which allows the operator to flexibly adjust the clutch state according to the actual conditions.

[0026] The generator set 7 used in this solution is a 50 kV permanent magnet generator set 7. Of course, other types of generator sets 7 can be selected as needed, and there are no restrictions here. Furthermore, batteries can be provided in the power generation assembly, if necessary, to store part of the electrical energy generated by the generator set 7 for emergency use.

[0027] The constructed air heat spray assembly is mainly used to provide high temperature and high pressure air, which is then sprayed into the soil through the ejector 11, thereby achieving soil repair.

[0028] Specifically, the air compressor 9 serves to supply compressed air and continuously feed it into the high-pressure air heater 10. The high-pressure air heater 10 continuously stores and heats the air, causing the temperature and pressure of the air to continuously rise. When the pressure rises to a preset parameter, the high-pressure air heater 10 sends the high-temperature and high-pressure air to the ejector 11 and then sprays it into the soil.

[0029] The high-pressure air heater 10 in this solution can heat the air to 300-750°C. An electric heater, such as an electric heating wire or an electric heating tube, is used as the heating method. The overall structure is can-shaped, and the can body of the high-pressure air heater 10 is made of carbon fiber composite material, which can ensure the high temperature resistance and high pressure resistance of the can body. The high-pressure air heater 10 should also be equipped with a pressure gauge and a temperature gauge to facilitate monitoring of the pressure and temperature values ​​of the air. A solenoid valve can be provided between the high-pressure air heater 10 and the ejector 11 if necessary to automatically control whether air is supplied to the ejector 11.

[0030] In this solution, as in Fig.As shown, the frame 1 is provided with a cross member 6 parallel to the rotary tiller main shaft 4, and the ejector 11 is arranged on the cross member 6. The ejector 11 is a T-shaped high-temperature and high-pressure air injector 11. That is, the injector 11 has a downwardly projecting spray end, so that when the frame 1 moves downward and the rotary tiller toothed blade 5 protrudes into the soil and starts working, the ejector 11 can be inserted into the soil, allowing high-temperature and high-pressure air to be more conveniently injected into the soil at a depth of 20 cm to 30 cm. After spraying high-temperature and high-pressure air into the soil, it can produce the following effects: 1. Carbonize the straw in the soil and return it to the field. This replaces the straw burning process and is more environmentally friendly and safer. 2. Under high temperature and high pressure, all kinds of grasses and grass seeds in the soil are carbonized and inactivated, thus achieving weed control without environmental pollution. 3. Under high temperature and high pressure, pests and eggs in the soil are inactivated to achieve the removal of pests in the soil. 4. Under high temperatures and high pressure, the acid, alkali and pesticide residues in the soil can evaporate and thus achieve soil remediation. 5. Under high temperatures and high pressure, heavy metals in the soil such as mercury (melting point -39 °C), lead (melting point 327.5 °C), cadmium (melting point 321 °C), etc. can melt and clump together into large molecules that cannot be easily absorbed by plants.

[0031] In this solution, the ejector 11 is located in front of the rotary cutter main shaft 4, so that a soil remediation effect of front extinguishing and reverse rotation can be achieved during operation.

[0032] Furthermore, the generator set 7, the air compressor 9, and the high-pressure air heater 10 are arranged above the frame 1. The frame 1 is also provided with a dust cover. The dust cover is arranged outside the generator set 7, the air compressor 9, and the high-pressure air heater 10 to perform a protective function.

[0033] In summary, this solution mainly adds a power generation assembly and an air-heat spray assembly to the existing rotary tiller structure. The power generation assembly can utilize the rotational energy of the rotary tiller's main shaft to generate electricity and power electrical components. This makes it convenient to use the device in fields where outdoor power supply is impractical. The air-heat spray assembly can generate high-temperature and high-pressure air, which is then sprayed into the soil through the ejector to remove pollutants such as straw, grass seeds, insect eggs, and other harmful substances in the soil. This achieves a soil remediation effect of front-wiping and reverse rotation.

[0034] The overall design of this system is simple, energy-saving and environmentally friendly, easy to operate and offers a wide range of application possibilities.
