Description

Technical Field

[0001] The present invention relates to the technical field of soil treatment, and particularly to a soil fumigation and disinfection device for agricultural production. Background Art

[0002] In agricultural production, soil quality plays a crucial role in the growth and development of crops. However, various pathogens, pests, weed seeds, and harmful microorganisms often exist in the soil. These harmful organisms will seriously affect the yield and quality of crops, resulting in poor growth of crops, frequent occurrence of diseases and pests, and even large-scale reduction in production.

[0003] Traditional soil treatment methods such as spraying chemical agents can, to a certain extent, inhibit some harmful organisms, but there are often problems such as uneven distribution of the agents, limited action depth, easy environmental pollution, and relatively large damage to the soil structure.

[0004] Existing soil fumigation equipment has deficiencies in sealing performance, and drug vapor is likely to leak. This not only reduces the effective utilization rate of the drug, increases costs, but also may have an adverse impact on the surrounding environment. Moreover, in the soil pretreatment link, there is a lack of effective soil loosening and leveling devices, resulting in poor air permeability and steam penetration of the soil, and unable to ensure the uniformity and durability of the fumigation effect.

[0005] Therefore, a soil fumigation and disinfection device for agricultural production is proposed. Summary of the Invention

A conical plate is fixedly connected between the plurality of carding frames and on the outer wall of the sleeve. Second toothed rings are fixedly connected to the side of the outer wall of the conical plate away from the support in an annular array. The second toothed rings are meshed with the third gear. A circular plate is fixedly connected to the outer wall of the sleeve and on the side of the second toothed ring close to the support. The outer wall of the circular plate is in contact with the third gear. A fourth spring is fixedly connected to the side of the circular plate close to the support. Sleeves are rotatably connected to both ends of the first round rod. First toothed rings are fixedly connected to the inner wall of the sleeves in an annular array. A cover plate is installed on the side of the sleeve close to the support. The cover plate is fixedly connected to the end of the fourth spring away from the circular plate.

[0011] Preferably, convex teeth are fixedly connected to the outer walls of the sleeves in an annular array. The length of the convex teeth is twice that of the carding frames. A baffle is arranged on the side of the carding frame away from the sleeve. The conical plate is inclined from the side close to the support to the other side.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. By the relative approach of the two arc-shaped plates, the air outlet below the atomizer is blocked, avoiding the leakage problem caused by the rotation of the partition plate at the air outlet below the atomizer, ensuring the efficient utilization of the drug vapor, and preventing the drug vapor from volatilizing to the outside due to sealing problems. The compartments formed by the partition plates inside the fan wheel are blocked from the outside, so that the drug vapor emitted by the atomizer can act efficiently on the soil below the atomizer, avoiding the emission of the vapor inside the fan wheel due to external factors, and increasing the treatment effect on the soil during fumigation;

[0017] 2. During the rotation of the combing frame, the soil clods and stones adhered in the soil will be lifted out of the soil due to the blockage of the baffle on the combing frame. The adhered soil clods and stones will roll towards the side of the conical plate close to the sleeve on the inclined surface of the conical plate and be arranged linearly on the soil, facilitating the collection and treatment of the soil clods and stones by the staff. At the same time, separating the adhered soil clods and stones from the loose soil can reduce the problem of poor downward injection of steam caused by stones, improve the penetration of steam in the soil, and improve the efficiency of soil fumigation;

[0018] 3. The pressing plate reciprocates up and down inside the second sliding plate, thereby realizing the patting and leveling of the soil below it, making the top of the soil more compact, making it difficult for steam to escape upward through the soil, and prolonging the fumigation time of the soil by the steam inside the soil. During the movement of the equipment, the second sliding plate slides on the soil, so that the soil is jointly affected by the first sliding plate and the second sliding plate to form a square grid, increasing the contact area between the inside of the soil and the outside, enabling the steam injected into the soil to escape through the notch formed by the cutting of the second sliding plate on the soil, and at the same time making the soil loose and divided so that it can be more quickly put into crop production in the later stage.

[0035] Embodiments of the present invention

[0036] Please refer to Figures 1 to 6 , a soil fumigation and disinfection device for agricultural production, including a bracket 1, an atomizer 2, and a partition component 3 arranged outside the atomizer 2. An air outlet is opened at the bottom of the atomizer 2. The atomizer 2 is fixedly connected to the bottom of the bracket 1. The partition component 3 includes a fan wheel 39 rotatably connected to the outer wall of the atomizer 2. A plurality of partition plates 310 are fixedly connected to the inside of the fan wheel 39 in an annular array. Transverse plates 31 are symmetrically and fixedly connected to the outer wall of the atomizer 2. Arc-shaped springs 33 are fixedly connected to the bottoms of the transverse plates 31. Arc-shaped plates 34 are slidably connected to the bottoms of the arc-shaped springs 33. Arc-shaped rods 32 are fixedly connected between the arc-shaped plates 34 and the transverse plates 31. Arc-shaped tooth plates 35 are fixedly connected to the sides of the two arc-shaped plates 34 close to each other. A first gear 36 is meshed between the two arc-shaped tooth plates 35. The first gear 36 is rotatably connected to the bottom of the atomizer 2. A plug plate 37 is rotatably connected to the bottom of the arc-shaped plate 34. A first spring 38 is sleeved at the rotational connection between the plug plate 37 and the arc-shaped plate 34. The side wall of the plug plate 37 is in contact with the partition plate 310.

[0037] A first sliding plate 311 is slidably connected to the outer wall of the partition plate 310. First tooth plates 312 are fixedly connected to both sides of the outer wall of the first sliding plate 311. A second tooth plate 313 is slidably connected to the inside of the fan wheel 39. Second springs 314 are fixedly connected between the second tooth plates 313 and the fan wheel 39. Second gears 315 are meshed between the second tooth plates 313 and the first tooth plates 312. The second gears 315 are rotatably connected to the inside of the fan wheel 39.

[0038] Saw teeth are provided at the bottom of the first sliding plate 311. When the second tooth plate 313 is not squeezed, it protrudes outside the fan wheel 39. When the second tooth plate 313 protrudes outside the fan wheel 39, the first sliding plate 311 is located inside the fan wheel 39. The arc-shaped plate 34 is attached to the outer wall of the atomizer 2. After the plug plate 37 is turned over, it is coplanar with the outer wall of the arc-shaped plate 34.

[0039] In the actual application of the embodiments of the present invention: The bracket 1 is connected to an external driving device, and the driving device pushes the bracket 1 to move forward on the land. The steam inside the atomizer 2 is discharged downward through the air outlet at its bottom. When moving, the sleeve 61 drives the fan wheel 39 and the partition plate 310 to rotate through the first transmission belt 4. During the rotation of the partition plate 310, the plug plate 37 will be driven to move. During the movement of the plug plate 37, the two arc plates 34 are relatively close to each other through the engagement of the arc-shaped tooth plate 35 and the first gear 36. When the arc plate 34 moves, the arc spring 33 is stretched and elastically extended, and the air outlet below the atomizer 2 is blocked, avoiding the problem of leakage at the air outlet below the atomizer 2 during the rotation of the partition plate 310, ensuring the efficient utilization of the drug steam, and preventing the drug steam from volatilizing to the outside due to sealing problems. When the arc plates 34 on both sides of the fan wheel 39 are closed, the plug plate 37 cannot continue to move under the push of the partition plate 310. Therefore, the plug plate 37 will rotate on the arc plate 34 and cause the first spring 38 to twist and generate torque. When the plug plate 37 flips to be coplanar with the arc plate 34, the stretched plug plate 37 elastically contracts and drives the arc plate 34 and the plug plate 37 to move away from each other. The plug plate 37 is no longer blocked by the partition plate 310 and returns to a state perpendicular to the arc plate 34 and fits with the next partition plate 310.

[0040] When the second tooth plate 313 on the side wall of the fan wheel 39 contacts the soil, the second tooth plate 313 will slide inside the fan wheel 39 towards the axis of the fan wheel 39 under the influence of the rotation of the fan wheel 39. When the second tooth plate 313 slides inside the fan wheel 39, the second spring 314 is stretched and elastically extended. During the sliding process of the second tooth plate 313 inside the fan wheel 39, the first slide plate 311 is driven to extend out of the fan wheel 39 through the second gear 315 and the first tooth plate 312. The first slide plate 311 extending out of the fan wheel 39 downward pierces into the soil, thereby blocking the compartments composed of the partition plates 310 inside the fan wheel 39 from the outside, so that the drug steam emitted by the atomizer 2 can act efficiently on the soil below the atomizer 2, avoiding the emission of the steam inside the fan wheel 39 due to external factors during fumigation, and increasing the treatment effect on the soil during fumigation.

[0041] Please refer to Figures 7 to 9, a carding assembly 6 is provided at the bottom of the bracket 1. The carding assembly 6 includes a first round rod 64 fixedly connected to the bottom of the bracket 1. A third gear 65 is rotatably connected to the side wall of the first round rod 64. A sleeve 66 is rotatably connected to the outer wall of the first round rod 64. Carding frames 610 are fixedly connected to the outer wall of the sleeve 66 in an annular array. A conical plate 611 is fixedly connected between the plurality of carding frames 610 and on the outer wall of the sleeve 66. Second toothed rings 67 are fixedly connected to the side of the conical plate 611 away from the bracket 1 in an annular array. The second toothed ring 67 meshes with the third gear 65. A circular plate 68 is fixedly connected to the outer wall of the sleeve 66 and on the side close to the bracket 1. The outer wall of the circular plate 68 is in contact with the third gear 65. A fourth spring 69 is fixedly connected to the side of the circular plate 68 close to the bracket 1. Sleeves 61 are rotatably connected to both ends of the first round rod 64. First toothed rings 62 are fixedly connected to the inner wall of the sleeves 61 in an annular array. A cover plate 63 is installed on the side of the sleeve 61 close to the bracket 1. The cover plate 63 is fixedly connected to the end of the fourth spring 69 away from the circular plate 68.

[0042] Convex teeth are fixedly connected to the outer walls of the sleeves 61 in an annular array. The length of the convex teeth is twice that of the carding frame 610. A baffle is provided on the side of the carding frame 610 away from the sleeve 66. The conical plate 611 is inclined from the side close to the bracket 1 to the other side. Helical tooth blocks are fixedly connected to the outer wall of the circular plate 68 in an annular array. A first transmission belt 4 is connected between the outer wall of the fan wheel 39 and the sleeve 61. A second transmission belt 5 is connected between the outer wall of the transmission shaft 73 and the fan wheel 39. The third gear 65 meshes with the second toothed ring 67 and the first toothed ring 62 respectively. The transmission ratio of the second toothed ring 67 and the first toothed ring 62 is three to one.

[0043] In the actual application of the embodiments of the present invention: When the device is in use, the convex teeth on the outer wall of the sleeve 61 will penetrate into the soil. As the whole bracket 1 moves, the sleeve 61 will rotate. During the rotation of the sleeve 61, it will drive the differential rotation of the sleeve 66 through the meshing of the first tooth ring 62 on its inner wall and the third gear 65, and the meshing of the third gear 65 and the second tooth ring 67. During the rotation of the sleeve 66, the soil to be fumigated will be loosened by the combing frame 610, avoiding the hardening and caking of the soil surface and affecting the fumigation effect. During the rotation of the combing frame 610, the soil clods and stones adhered in the soil will be lifted out of the soil due to the blocking of the baffle on the combing frame 610. When the adhered soil clods and stones rotate above the sleeve 66, they will fall onto the surface of the conical plate 611 due to their own gravity. At this time, because the surface of the conical plate 611 is inclined, the adhered soil clods and stones will roll down on the inclined surface of the conical plate 611 towards the side of the conical plate 611 close to the sleeve 61 and be arranged linearly on the soil, facilitating the collection and treatment of the soil clods and stones by the staff. At the same time, separating the adhered soil clods and stones from the loose soil can reduce the problem of poor downward injection of steam caused by stones, improve the penetration of steam in the soil, and improve the efficiency of soil fumigation.

[0044] Please refer to Figure 10 , a leveling assembly 7 is provided at the bottom of the bracket 1. The leveling assembly 7 includes a second round rod 71 fixedly connected to the bottom of the bracket 1. First bevel gears 72 are symmetrically and rotatably connected to both ends of the second round rod 71. Transmission shafts 73 are fixedly connected to the sides of the first bevel gears 72 away from the bracket 1. Second sliding plates 74 are fixedly connected to the outer wall of the second round rod 71 in a linear array. Double threaded rods 75 are rotatably connected to the outer walls of the second sliding plates 74. A second bevel gear 76 is fixedly connected to the top of the double threaded rod 75. The second bevel gear 76 meshes with the first bevel gear 72. A pressing plate 77 is slidably connected to the outer wall of the double threaded rod 75. The side of the pressing plate 77 close to the fan wheel 39 is a folded angle that rises upwards.

[0045] In the actual application of the embodiments of the present invention: when the fan wheel 39 rotates, it will drive the first bevel gear 72 to rotate together through the second transmission belt 5 and the transmission shaft 73. During the rotation of the first bevel gear 72, it will drive the double threaded rod 75 engaged with it to rotate together. The rotation of the double threaded rod 75 drives the pressing plate 77 to slide up and down reciprocally inside the second sliding plate 74, thereby realizing the patting and leveling of the soil below the pressing plate 77, making the top of the soil more compact, making it difficult for steam to escape upward through the soil, extending the fumigation time of the steam in the soil to the soil, and through the sliding of the second sliding plate 74 on the soil when the equipment moves, the soil forms a square grid under the combined action of the first sliding plate 311 and the second sliding plate 74, increasing the contact area between the inside of the soil and the outside world, enabling the steam injected into the soil to escape through the notch formed by the cutting of the second sliding plate 74 on the soil, and at the same time making the soil loose and divided so that it can be put into the production of crops faster in the later stage.
