Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to soil disinfection equipment for vegetable greenhouses. Background Art

[0002] With the rapid development of protected land and facility agriculture, the emergence of vegetable greenhouses allows people to eat off-season vegetables, which is of great significance for meeting people's demand for fresh vegetables all year round. The large-scale planting of high-value-added vegetable crops has created huge economic benefits for farmers and enterprises. However, due to the use of protected cultivation and intensive planting, coupled with the unscientific use of pesticides and fertilizers, soil continuous cropping obstacles have become more serious year by year, seriously affecting crop yield and quality.

[0003] There are generally several methods for preventing and controlling soil continuous cropping obstacles: biological control, which uses toxic gases released by specific organic matter to kill soil diseases. Its disinfection cycle is long and time-consuming and labor-intensive, and is greatly affected by ambient temperature. It is often treated at high temperatures in summer; chemical control, which uses chemical agents mixed with soil for disinfection. It has the advantages of high disinfection efficiency and low cost, but it also destroys the beneficial microbial communities in the soil during disinfection, and is extremely harmful to the environment and people. Soil steam disinfection is a physical control measure that is both green and environmentally friendly, safe and reliable, and can be planted within a short time after treatment, so it is indeed feasible to use high-temperature steam to solve the problem of continuous cropping obstacles.

[0004] At present, the steam sterilizer is generally placed on the field and laid on the soil through a long pipe. Then a high-temperature resistant film is covered on the soil and the long pipe and the four sides of the high-temperature resistant film are compacted. The steam generated by the steam sterilizer is passed through the long pipe into the space between the high-temperature film and the soil to perform high-temperature disinfection on the soil. After disinfecting a small area, the long pipe and the high-temperature resistant film are laid to other areas. The operation is relatively cumbersome, the entire process relies on manpower, and the labor intensity is high.

[0005] Therefore, it is necessary to provide a vegetable greenhouse soil disinfection equipment to solve the above problems. Utility Model Content

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Reference Figures 1 to 5 As shown, the utility model provides a vegetable greenhouse soil disinfection device, including a trolley 1, one end of the trolley 1 is hinged with a traction frame 2, the top of the trolley 1 is fixedly connected to a supporting plate 3, a steam generator 4 is fixedly installed on the supporting plate 3, a jet assembly is arranged below the supporting plate 3, the jet assembly is connected with the steam generator 4 through a pipeline, a connecting assembly is arranged on the supporting plate 3, the jet assembly is connected with the supporting plate 3 through the connecting assembly, and a lifting mechanism is arranged on the trolley 1, and the lifting mechanism is used for lifting the jet assembly.

[0029] In this embodiment, the steam generator 4 is a commercially available component, and its working principle is prior art, which will not be described in detail here.

[0030] The trolley 1 can be connected to the tractor by the traction frame 2, so that the tractor pulls the trolley 1 to move intermittently in the field;

[0031] The jet assembly can be inserted into the soil, and the high-temperature steam generated by the steam generator 4 can be sprayed onto the surface and inside of the soil through the pipeline to achieve soil disinfection;

[0032] The depth of the jet assembly inserted into the soil can be controlled by the provided lifting mechanism. After the soil in the unit area is disinfected, the jet assembly can be controlled to be pulled out of the soil and a certain ground clearance can be controlled to facilitate the tractor to pull the trolley 1 forward to disinfect the soil in the next unit area.

[0033] The utility model has the advantages of simple operation, high automation and can reduce the labor intensity of personnel.

[0034] Furthermore, the jet assembly includes a mounting plate 17, and main pipes 18 are fixedly installed on both sides of the bottom end of the mounting plate 17. A plurality of branch pipes 19 are arranged in parallel between the two main pipes 18. The distance between two adjacent branch pipes 19 is equal, and the two ends of the branch pipes 19 are fixedly connected to the main pipes 18 located on both sides of the mounting plate 17. Both main pipes 18 are fixedly connected to the steam generator 4 through pipelines. A plurality of jet components are evenly spaced on the branch pipes 19, and the jet components are fixedly connected to the branch pipes 19.

[0035] By connecting a plurality of branch pipes 19 between two main pipes 18, the steam generator 4 can be first connected to the main pipe 18 through the pipe, and then the steam is diverted from the main pipe 18 to each branch pipe 19. By uniformly arranging the branch pipes 19, the balance of steam pressure on each branch pipe 19 can be ensured, and high-temperature sterilization can be performed simultaneously on the inside and the surface of the soil through the jet parts arranged on the branch pipes 19.

[0036] Furthermore, the jetting member includes a vertical conduit 16 fixedly connected to the bottom end of the branch conduit 19 , a plurality of air outlets are provided on the side wall of the vertical conduit 16 , and the spacing between two adjacent air outlets is equal. The bottom end of the vertical conduit 16 is fixedly connected with a cone cap 13 .

[0037] The bottom end of the vertical conduit 16 is sealed by the provided cone cap 13, and the jet is ejected through a plurality of air outlets provided on the peripheral surface of the vertical conduit 16, so that the bottom end of the vertical conduit 16 is conveniently inserted into the soil to avoid blockage of the air outlets by the soil. By controlling the insertion depth of the vertical conduit 16 into the soil, the gas ejected from the air outlets on the upper peripheral surface of the vertical conduit 16 that has not entered the soil can disinfect the soil surface, and at the same time, the air outlets that have entered the soil can directly act on the inside of the soil for disinfection.

[0038] Furthermore, in order to improve the disinfection effect and prevent the high-temperature steam from spreading to the surroundings, an air collecting hood 5 is provided on the mounting plate 17, and the jet component is arranged inside the air collecting hood 5, and the air collecting hood 5 is connected to the supporting plate 3 through a connecting assembly.

[0039] Furthermore, the connecting assembly includes a plurality of vertical guide rods 6 slidably connected to both sides of the supporting plate 3, the top of the vertical guide rod 6 is fixedly connected with an anti-slip block 20, and the vertical guide rod 6 is sequentially sleeved with a spring 1 7, a limit plate 8, and a spring 2 9 from top to bottom, and the top of the air collecting hood 5 is provided with a plurality of through holes, and the through holes are arranged corresponding to the vertical guide rod 6, and the air collecting hood 5 is slidably connected to the vertical guide rod 6 through the through holes, the spring 1 7 is arranged between the anti-slip block 20 and the supporting plate 3, and the two ends of the spring 1 7 are respectively abutted against the anti-slip block 20 and the supporting plate 3, the limit plate 8 is fixedly connected to the vertical guide rod 6, and the limit plate 8 is arranged between the supporting plate 3 and the air collecting hood 5, the spring 2 9 is arranged between the limit plate 8 and the air collecting hood 5, and the two ends of the spring 2 9 are respectively abutted against the limit plate 8 and the air collecting hood 5, and the bottom end of the vertical guide rod 6 is fixedly connected to the top of the mounting plate 17.

[0040] The connection between the air collecting hood 5 and the mounting plate 17 and the supporting plate 3 is realized by the provided vertical guide rod 6, and the flexible connection between the vertical guide rod 6 and the supporting plate 3 is realized by the provided spring 1 7; the provided spring 2 9 can be used to press the air collecting hood 5 during the process of the jet component slowly being inserted into the soil, so as to ensure that the air collecting hood 5 is tightly fastened to the soil to ensure the sealing. Specifically, when the lifting mechanism drives the mounting plate 17 to descend, the vertical guide rod 6 moves downward to compress the spring 1 7, and the jet component is gradually inserted into the soil. The air collecting hood 5 contacts the soil and stops descending under the obstruction of the soil. At this time, the mounting plate 17 drives the jet component to continue to move downward. As the depth of the jet component inserted into the soil increases, the limit plate 8 fixedly mounted on the vertical guide rod 6 begins to squeeze the spring 2 9, and the spring 2 9 applies elastic force to the air collecting hood 5, so that the air collecting hood 5 contacts the soil more closely, thereby further improving the sealing.

[0041] Furthermore, the lifting mechanism includes a driving assembly fixedly arranged in the middle of the top of the trolley 1, and vertical racks 10 are fixedly connected to both sides of the top of the supporting plate 3. The two vertical racks 10 are symmetrically arranged about the driving assembly. Square holes are opened on the air collecting hood 5 and the supporting plate 3. The top of the vertical rack 10 passes through the air collecting hood 5 and the supporting plate 3 from bottom to top through the square holes, and the length of the vertical rack 10 is not less than the length of the vertical guide rod 6. The driving assembly is connected to a gear 12 for transmission, and the gear 12 is meshed with the vertical rack 10.

[0042] The gear 12 is driven to rotate by the drive assembly, and the gear 12 is meshed with the vertical rack 10, so that the vertical rack 10 passes through the air collecting hood 5 and the supporting plate 3 and moves up and down under the guidance of the vertical guide rod 6, so that the vertical rack 10 drives the mounting plate 17 to rise and fall.

[0043] Furthermore, the driving assembly includes a motor 14 fixedly installed in the middle of the top end of the trolley 1, and rotating shafts 11 are symmetrically arranged on both sides of the motor 14. The two rotating shafts 11 are rotatably connected to the frame of the trolley 1, and the output end of the motor 14 is fixedly connected to the input end of the T-type reduction gear box 15. The two output ends of the T-type reduction gear box 15 have the same direction, and the two output ends of the T-type reduction gear box 15 are respectively fixedly connected to one end of the rotating shaft 11, and the gear 12 is fixedly connected to the other end of the rotating shaft 11.

[0044] In this embodiment, the T-type reduction gearbox 15 is a commercially available part, according to the prior art, and the motor 14 is a servo motor, and the direction, speed, number of rotations, and operating interval of the motor 14 can be controlled by an external PLC.

[0045] The motor 14 is set to rotate, and the T-type reduction gear box 15 is used to reduce the speed and increase the torque, so as to drive the gear 12 to rotate, and the gear 12 is meshed with the vertical rack 10 to realize the lifting of the mounting plate 17 and the air collecting hood 5.

[0046] The vegetable greenhouse soil disinfection equipment provided by the utility model has the following working principles: when in use, the traction frame 2 is connected to the rear towing hook of the tractor. In order to improve the disinfection effect on the soil, the soil in the vegetable greenhouse can be turned over first, and the steam generator 4 is started to preheat and heat up to reach the use state, and then the motor 14 is started to run, and the motor 14 drives the gear 12 to rotate. Under the meshing transmission of the gear 12 and the vertical rack 10, the gear 12 drives the air collecting hood 5 and the mounting plate 17 to move downward, and the mounting plate 17 drives the jet part to be inserted into the soil to a preset depth. The air collecting hood 5 is pressed against the soil under the action of the spring 29. At this time, the motor 14 stops running, and the steam is turned on. The valve of the generator 4 is respectively sprayed onto the inside and surface of the soil through the pipeline, the main pipeline 18 and the branch pipeline 19, and finally through the air holes on the vertical guide tube 16 to achieve high-temperature disinfection. After the disinfection of the soil in the unit area below the gas collecting hood 5 is completed, the motor 14 is started and rotated in the opposite direction. Under the meshing transmission of the gear 12 and the vertical rack 10, the vertical rack 10 pulls the mounting plate 17, and the mounting plate 17 supports the gas collecting hood 5 and moves upward together, and the ejection part is separated from the soil. When the ejection part reaches the preset ground clearance, the motor 14 stops rotating, and the tractor pulls the trolley 1 to move to the next adjacent unit area, and the above steps are repeated for disinfection.
