Description

Technical Field

[0001] The invention belongs to the technical field of pest control, and in particular relates to a prevention and control mechanism for forestry soil pests. Background Art

[0002] With the development of intensive farming, crop rotation is becoming increasingly difficult. This is because, due to a lack of effective control techniques, farmers often use chemical pesticides for root irrigation to control soil pests and diseases. This not only pollutes the soil but also easily leads to excessive pesticide residues, poisoning, and even groundwater contamination. Consequently, years of continuous cultivation lead to the accumulation of soil-borne pathogens and insect eggs, resulting in a serious incidence of soil-borne pests and diseases, a prominent problem in current agricultural production. As the primary habitat for pests and diseases, soil treatment is crucial, as long-term continuous cropping increases pest and disease density. Currently, soil treatment is typically performed by spraying disinfectants onto fields between crop plantings. However, manual spraying is inefficient, and since the fields are free from the protection of crops, most of the disinfectant sprayed is dispersed by wind, leaving only a small amount attached to the soil surface. However, many pathogens and insect eggs are hidden in the soil layer approximately ten centimeters below the surface. If these pathogens and eggs are not effectively eliminated, various pests and diseases will reappear when other crops are subsequently planted.

[0003] In order to solve the above problems, this application proposes a mechanism for preventing and controlling forestry soil pests and diseases. Summary of the Invention

[0004] To solve the problems raised in the above background technology.

The adjustable temperature can ensure that the appropriate temperature sufficient to kill specific types of pests and diseases is accurately set, thereby improving the pertinence and effectiveness of the pest control. The reciprocating pest control operation can make the high-temperature steam more evenly distributed in the underground soil, avoiding the situation where the local temperature is too high or too low, thereby ensuring that the pests and diseases in the entire pest control area can be effectively affected by the temperature, improving the comprehensiveness and thoroughness of the pest control, breaking up the soil to make it loose, and the loose soil structure can allow the steam to penetrate deeper into the soil, ensuring that the steam can reach the deep areas where the pests and diseases may be hiding, thereby improving the comprehensiveness and effectiveness of the pest control.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By setting up a high-temperature disinfection component, and through the coordinated use of the high-temperature steam box, refrigeration box, cold air telescopic conveying pipe, lifting plate, L-shaped connecting pipe, shovel plate and covering plate and other structures, the air pump in the high-temperature steam box guides the hot air into the L-shaped connecting pipe through the high-temperature telescopic conveying pipe and the temperature regulating pipe, and then discharges it through the through hole opened on the surface of the tail end of the L-shaped connecting pipe to perform high-temperature steam disinfection on the soil. The high-temperature steam can quickly and effectively kill pathogens, insect eggs and larvae in the soil. The higher temperature can destroy the cell structure and physiological function of pests and pathogens, making them unable to survive and reproduce. Secondly, steam disinfection is relatively environmentally friendly, does not leave any chemical residues, has little impact on the soil ecosystem, and helps maintain the natural fertility of the soil and the balance of the microbial community;

[0020] The regulating plate is set up in conjunction with the steam temperature to adjust the temperature according to the different temperature tolerance of different types of pests and diseases. The adjustable temperature can ensure that the appropriate temperature is accurately set for specific types of pests and diseases to kill them, thereby improving the pertinence and effectiveness of the pest control. Secondly, different soil textures and environmental conditions will also affect the penetration and heat transfer of steam. By adjusting the temperature, it can adapt to various complex soil conditions and ensure that the steam can act evenly and fully on the pests and diseases in the soil, reducing the disinfecting angle of pest control. Furthermore, the adjustable temperature can reduce excessive damage to beneficial microorganisms in the soil. While killing pests and diseases, it can reserve a certain living space for beneficial microorganisms, help maintain the balance and stability of the soil ecosystem, and promote the health and sustainable development of forestry soil. In addition, the adjustable temperature can also be flexibly adjusted according to different seasons and climatic conditions. For example, in cold seasons, the temperature can be appropriately increased to ensure the pest control effect. In hot seasons, the temperature can be appropriately lowered to avoid excessive temperature causing adverse effects on soil structure and nutrients.

[0021] The shovel board is provided so that when the soil is disinfected with high temperature, the shovel board can scoop up the soil, and the extension amount of the tail end of the L-shaped connecting pipe can be controlled by the hydraulic rod, so that the tail end of the L-shaped connecting pipe can be under the ground, promoting precise disinfection. The higher steam temperature can directly reach the area where underground pests and pathogens are located, achieving targeted and precise elimination, improving the pertinence and effect of prevention and control, and sufficient temperature can make the steam penetrate into the soil layer, not only to treat pests and diseases in the surface soil, but also to effectively eliminate hidden dangers in the deep soil, reducing the possibility of recurrence of pests and diseases. The steam diffuses underground and can act evenly on the surrounding soil, ensuring that there are no dead ends in disinfection and comprehensively purifying the soil environment.

[0022] The shovel board can also prevent the tail end of the L-shaped connecting pipe from directly contacting the ground, causing damage to the tail end of the L-shaped connecting pipe and the ground, and can also prevent soil from entering the tail end of the L-shaped connecting pipe. In combination with the provided covering plate, the soil shoveled by the shovel board can be smoothed by the covering plate after high-temperature disinfection.

[0023] When the mixed steam is discharged through the L-shaped connecting pipe, it can drive the impeller to rotate, which in turn can cause the crushing rod to rotate on the surface of the bracket, breaking up the soil that has entered the L-shaped connecting pipe, preventing the tail end of the L-shaped connecting pipe from being blocked after long-term use, and ensuring the smooth passage of the mixed steam;

[0024] 2. By setting up a pest control balancing component, and by using the connecting sleeve, adjusting sleeve, sliding part, ground wheel, transmission rod, two-way screw segment, universal joint, sliding sleeve and sliding rod and other structures in coordination, when the device moves for pest control, the connecting sleeve can slide back and forth on the bottom surface of the lifting plate, thereby prompting the L-shaped connecting pipe to follow the reciprocating movement and perform reciprocating pest control operations. This reciprocating movement can make the high-temperature steam more evenly distributed in the underground soil, avoiding the situation where the local temperature is too high or too low, thereby ensuring that the pests and diseases in the entire pest control area can be effectively affected by the temperature, improving the comprehensiveness and thoroughness of the pest control, and the reciprocating left and right movement combined with the stable temperature can achieve efficient pest control effects without destroying the physical structure of the soil, thereby ensuring the fertility and air permeability of the forestry soil;

[0025] 3. By setting up a soil-breaking and loosening component, Tonghua's U-shaped lifting frame, soil-breaking roller, baffle, adjustment shield and slide structure are used in conjunction. When the lifting plate moves downward, it can drive the U-shaped lifting frame connected to it to move downward, control the rotation of the soil-breaking roller, break up the soil and make it loose. The loose soil structure can allow steam to penetrate deeper into the soil, ensuring that steam can reach deep areas where pests and diseases may be hidden, thereby improving the comprehensiveness and effectiveness of pest control. The broken loose soil can reduce the close contact between soil particles, improve the conduction of heat in the soil, make the high temperature more evenly distributed, and kill pests and diseases more effectively, allowing steam to fully contact pathogens, eggs and larvae hidden in the soil cracks, thereby improving the success rate of pest control. Loosening the soil can increase the aeration of the soil, which helps the soil to restore normal gas exchange after pest control, promotes the activity of beneficial microorganisms and the respiration of plant roots, and loose soil requires less steam energy to reach the ideal pest control temperature, thereby reducing energy consumption and prevention costs.

[0026] The elastically connected adjustment baffle, which is connected through the cooperation of spring 2 and the adjustment rod, can apply appropriate pressure to the soil when covering it, so that the soil particles are rearranged to form a more stable structure, which is conducive to water penetration and root growth, and improves the durability of the steam disinfection effect. Timely covering of the soil after steam disinfection can reduce the interference of external factors on the treated area after disinfection, and keep the temperature and humidity conditions in the disinfection area relatively stable, thereby extending the effective action time of steam disinfection, enhancing the effect of preventing and controlling pests and diseases, and enhancing the soil's water and fertilizer retention capacity. The elastically set adjustment baffle can better fit the soil surface, reduce water evaporation and nutrient loss, and provide a more favorable soil environment for tree growth. Suitable covering can provide a relatively stable living environment for soil microorganisms, which helps them to recolonize and reproduce in the soil after disinfection, and has a positive effect on the recovery and balance of the soil ecosystem.

The hot air inlet 29 opened at one end of the temperature regulating pipe 28 is connected to one end of the high-temperature telescopic conveying pipe 25, and the other end of the high-temperature telescopic conveying pipe 25 is connected to the high-temperature steam box 22. High-temperature steam can quickly and effectively kill pathogens, insect eggs and larvae in the soil.

Secondly, steam disinfection is relatively environmentally friendly, will not leave chemical residues, and has little impact on the soil ecosystem, which helps to maintain the natural fertility of the soil and the balance of the microbial community.

[0052] A hydraulic rod 24 is installed on the surface of the fixed plate 21. The piston end of the hydraulic rod 24 passes through one end of the fixed plate 21 and is connected to the lifting plate 211 arranged in the treatment box 1. An L-shaped connecting pipe 212 is arranged on the bottom surface of the lifting plate 211. A shovel plate 213 is fixed to the outer side of the bottom of the L-shaped connecting pipe 212, and a covering plate 214 is integrally formed on the surface of the shovel plate 213.

[0053] A refrigeration box 23 is installed on the surface of the fixed plate 21 . A cold air telescopic conveying pipe 26 is connected to the surface of the refrigeration box 23 . A cold air inlet 210 opened at one end of the temperature regulating pipe 28 is connected to one end of the cold air telescopic conveying pipe 26 .

[0054] The surface of the temperature regulating tube 28 is slidably connected to an adjusting plate 27, which is fixedly mounted on the bottom surface of the fixed plate 21. An adjusting port 1 215 and an adjusting port 2 216 are provided on the surface of the adjusting plate 27. The adjusting port 1 215 and the adjusting port 2 216 correspond to the cold air inlet 210 and the hot air inlet 29 respectively, so as to facilitate the adjustment of the temperature of the steam so as to facilitate the different temperature tolerance of different types of pests and diseases. The adjustable temperature can ensure that the appropriate temperature for killing specific types of pests and diseases is accurately set, thereby improving the pertinence and effectiveness of the disinfection.

[0055] A bracket 217 is installed in the L-shaped connecting pipe 212 . A crushing rotating rod 218 is rotatably connected to the surface of the bracket 217 . An impeller 219 is installed at one end of the crushing rotating rod 218 .

[0056] The surface of the treatment box 1 is slidably connected to a disinfection balancing assembly 3, which includes a connecting sleeve 31, a sliding strip 32, an adjustment sleeve 33, a spring 1 34, a sliding member 35, a ground wheel 36, a transmission rod 37, a bidirectional screw rod segment 38, a universal joint 1 39, a sliding sleeve 310, a sliding rod 311, and a universal joint 2 312;

[0057] A connecting sleeve 31 is fixedly installed at one end of the L-shaped connecting tube 212, and an adjusting sleeve 33 is provided on the outside of the treatment box 1. The lifting plate 211 extends a strip groove opened on the surface of the treatment box 1 and is connected to the adjusting sleeve 33. The surface of the adjusting sleeve 33 is rotatably connected to the transmission rod 37. The connecting sleeve 31 is threadedly connected to the surface of the bidirectional screw segment 38 opened on the surface of the transmission rod 37. The connecting sleeve 31 is slidably connected to the surface of the sliding strip plate 32 fixedly installed on the bottom surface of the lifting plate 211.

[0058] The cam 312 is connected to the cam 313 by a spring 34 which is arranged on the inside of the cam 313 so as to allow the cam 313 to move in a reverse direction and thereby prevent the cam 313 from sliding out of the cam 313 and causing the cam 313 to move in a reverse direction.

[0059] A soil breaking and loosening assembly 4 is installed in the treatment box 1, and the soil breaking and loosening assembly 4 includes a U-shaped lifting frame 41, a soil breaking roller 42, a slide 43, a baffle 44, an adjustment shield 45, a rotating frame 46, an adjustment rod 47, a spring 48, a slide 49, and an adjustment bolt 410.

[0060] A U-shaped lifting frame 41 is slidably connected to the inner wall of the treatment box 1 in a slide groove 43, and a soil-breaking roller 42 is rotatably connected to the U-shaped lifting frame 41. The U-shaped lifting frame 41 is connected to the lifting plate 211. A baffle 44 is fixedly installed in the treatment box 1. The soil-breaking roller 42 is driven to rotate by a servo motor to break up the soil and make it loose. The loose soil structure allows steam to penetrate deeper into the soil, ensuring that the steam can reach deep areas where pests and diseases may be hiding, thereby improving the comprehensiveness and effectiveness of the disinfection.

[0061] The inner wall of the treatment box 1 is rotatably connected to an adjusting baffle 45 through a rotating shaft, and a rotating frame 46 is fixed on the surface of the adjusting baffle 45, and an adjusting rod 47 is rotatably connected to the surface of the rotating frame 46. A slide 49 is slid on the outside of the adjusting rod 47, and the slide 49 is fixedly installed on the surface of the treatment box 1. A spring 2 48 is provided on the outside of the adjusting rod 47 and is located between the rotating frame 46 and the slide 49. An adjusting bolt 410 is threadedly connected to the outside of one end of the adjusting rod 47 extending out of the slide 49. Covering the soil in time after steam disinfection can reduce the interference of external factors on the treatment area after disinfection, and keep the temperature and humidity conditions in the disinfection area relatively stable, thereby extending the effective action time of steam disinfection, enhancing the effect of preventing and controlling pests and diseases, and enhancing the water and fertilizer retention capacity of the soil.

[0062] The working principle and use process of the present invention are as follows: when the pest control device is working, the device is first pushed to the land that needs to be controlled, and the extension of the piston end of the hydraulic rod 24 is controlled to cause the lifting plate 211 slidably connected to the treatment box 1 to move downward, thereby enabling the multiple L-shaped connecting pipes 212 arranged on the bottom surface of the lifting plate 211 to move downward, and at this time, the air pump in the high-temperature steam box 22 is controlled to introduce hot air into the L-shaped connecting pipe 212 through the high-temperature telescopic conveying pipe 25 and the temperature regulating pipe 28, and then discharged through the through hole opened on the tail end surface of the L-shaped connecting pipe 212 to perform high-temperature steam disinfection on the soil. The high-temperature steam can quickly and effectively kill pathogens, insect eggs and larvae in the soil. The higher temperature can destroy the cell structure and physiological function of pests and pathogens, making them unable to survive and reproduce. Secondly, steam disinfection is relatively environmentally friendly, will not leave chemical residues, has little impact on the soil ecosystem, and helps to maintain the natural fertility of the soil and the balance of microbial communities;

[0063] The adjustment plate 27 is provided in conjunction with the lifting plate 211. When the lifting plate 211 pushes the L-shaped connecting pipe 212 downward, the size of the communication between the adjustment port 1 215 and the adjustment port 2 216 opened on the surface of the adjustment plate 27 relative to the cold air inlet 210 and the hot air inlet 29 can be changed, so that the temperature of the steam can be adjusted. In order to adapt to the different types of pests and diseases to different degrees of temperature tolerance, the adjustable temperature can ensure that the appropriate temperature for killing specific types of pests and diseases can be accurately set, thereby improving the pertinence and effectiveness of the disinfecting. Secondly, different soil textures and environmental conditions will also affect the penetration and heat transfer of steam. By adjusting the temperature, it can be adapted to the specific types of pests and diseases. It can adapt to various complex soil conditions and ensure that steam can evenly and fully act on pests and diseases in the soil, reducing the dead angle of pest control. Moreover, the adjustable temperature can reduce excessive damage to beneficial microorganisms in the soil. While killing pests and diseases, it can reserve a certain living space for beneficial microorganisms, which helps to maintain the balance and stability of the soil ecosystem and promote the health and sustainable development of forestry soil. In addition, the adjustable temperature can also be flexibly adjusted according to different seasons and climatic conditions. For example, in cold seasons, the temperature can be appropriately increased to ensure the pest control effect. In hot seasons, the temperature can be appropriately lowered to avoid excessively high temperatures causing adverse effects on soil structure and nutrients.

[0064] The shovel board 213 is provided so that when the soil is sterilized with high temperature, the shovel board 213 can scoop up the soil, and the extension amount of the tail end of the L-shaped connecting pipe 212 can be controlled by the hydraulic rod 24, so that the tail end of the L-shaped connecting pipe 212 can be placed under the ground, which promotes precise sterilization. The higher steam temperature can directly reach the area where underground pests and pathogens are located, achieving targeted and precise elimination, improving the pertinence and effect of prevention and control, and sufficient temperature can make the steam penetrate into the soil layer, not only treating pests and diseases in the surface soil, but also effectively removing hidden dangers in the deep soil, reducing the possibility of recurrence of pests and diseases, and the steam diffuses underground and can evenly act on the surrounding soil, ensuring sterilization without dead ends and comprehensively purifying the soil environment;

[0065] The shovel board 213 can also prevent the tail end of the L-shaped connecting pipe 212 from directly contacting the ground, causing the tail end of the L-shaped connecting pipe 212 to collide with the ground and be damaged, and can also prevent soil from entering the tail end of the L-shaped connecting pipe 212. In combination with the provided covering plate 214, the soil shoveled by the shovel board 213 can be smoothed by the covering plate 214 after high-temperature disinfection.

[0066] When the mixed steam is discharged through the L-shaped connecting pipe 212, it can drive the impeller 219 to rotate, thereby causing the crushing rotating rod 218 to rotate on the surface of the bracket 217, thereby breaking up and crushing the soil that has entered the L-shaped connecting pipe 212, preventing the tail end of the L-shaped connecting pipe 212 from being blocked after long-term use, and ensuring the smooth passage of the mixed steam;

[0067] When the lifting plate 211 moves downward, the adjusting sleeves 33 installed at both ends thereof can follow and move downward, and the ground wheel 36 at the bottom end of the sliding member 35 elastically slidably connected to the adjusting sleeve 33 through the spring 1 34 can contact the ground. When the device moves for disinfection, the sliding rod 311 can be rotated under the setting of the universal joint 2 312, and the sliding rod 311 slides vertically in the sliding sleeve 310 to perform position compensation, thereby also enabling the sliding sleeve 310 to rotate, and with the cooperation of the universal joint 1 39, the transmission rod 37 rotatably connected to the adjusting sleeve 33 can be rotated, and the bidirectional screw segment 38 and the threaded connection on the surface of the bidirectional screw segment 38 can be rotated. With the coordinated use of the connecting sleeve 31, the connecting sleeve 31 can slide back and forth on the bottom surface of the lifting plate 211, thereby prompting the L-shaped connecting pipe 212 to follow the reciprocating movement to perform a reciprocating pest control operation. This reciprocating movement can make the high-temperature steam more evenly distributed in the underground soil, avoiding the situation where the local temperature is too high or too low, thereby ensuring that the pests and diseases in the entire pest control area can be effectively affected by the temperature, improving the comprehensiveness and thoroughness of the pest control. The reciprocating left and right movement combined with the stable temperature can achieve an efficient pest control effect without destroying the physical structure of the soil, thereby ensuring the fertility and air permeability of the forestry soil;

[0068] When the lifting plate 211 moves downward, it can drive the U-shaped lifting frame 41 connected thereto to move downward, so that the soil-breaking roller 42 extends into the ground. When the soil-breaking roller 42 is controlled to rotate by external power (a power transmission structure such as a servo motor), the soil is broken up and made loose. The loose soil structure allows steam to penetrate deeper into the soil, ensuring that the steam can reach deep areas where pests and diseases may be hidden, thereby improving the comprehensiveness and effectiveness of the pest control. The broken loose soil can reduce the close contact between soil particles, improve the conduction of heat in the soil, make the high temperature more evenly distributed, and kill pests and diseases more effectively, allowing steam to fully contact pathogens, eggs and larvae hidden in the cracks of the soil, thereby improving the success rate of the pest control. Loosening the soil can increase the aeration of the soil, which helps the soil to restore normal gas exchange after the pest control, promotes the activity of beneficial microorganisms and the respiration of plant roots, and the loose soil requires less steam energy to reach the ideal pest control temperature, thereby reducing energy consumption and prevention and control costs.

[0069] The elastically connected adjustment baffle 45, which is connected through the cooperation of structures such as spring 2 48 and adjustment rod 47, can apply appropriate pressure to the soil when covering it, so that the soil particles are rearranged to form a more stable structure, which is conducive to water penetration and root growth, and improves the durability of the steam disinfection effect. Timely covering of the soil after steam disinfection can reduce the interference of external factors on the treated area after disinfection, and keep the temperature and humidity conditions in the disinfection area relatively stable, thereby extending the effective action time of steam disinfection, enhancing the effect of preventing and controlling pests and diseases, and enhancing the water and fertilizer retention capacity of the soil. The elastically set adjustment baffle 45 can better fit the soil surface, reduce water evaporation and nutrient loss, and provide a more favorable soil environment for tree growth. Suitable covering can provide a relatively stable living environment for soil microorganisms, which helps them to recolonize and reproduce in the soil after disinfection, and has a positive effect on the recovery and balance of the soil ecosystem.
