[0002] In agricultural production, soil quality plays a vital role in the growth and development of crops.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiments of the present invention See also Figures 1 to 6A soil fumigation and disinfection device for agricultural production comprises a bracket 1, an atomizer 2 and a partition assembly 3 arranged outside the atomizer 2, an air outlet is provided at the bottom of the atomizer 2, the atomizer 2 is fixedly connected to the bottom of the bracket 1, the partition assembly 3 comprises a fan wheel 39 rotatably connected to the outer wall of the atomizer 2, the interior of the fan wheel 39 is distributed in an annular array and fixedly connected with a partition plate 310, the outer wall of the atomizer 2 is symmetrically fixedly connected with a horizontal plate 31, the bottom of the horizontal plate 31 is fixedly connected with an arc spring 33, the arc spring 3 3 are slidably connected with an arc plate 34 at the bottom, an arc rod 32 is fixedly connected between the arc plate 34 and the horizontal plate 31, an arc tooth plate 35 is fixedly connected to the side close to the two arc plates 34, a first gear 36 is meshed between the two arc tooth plates 35, the first gear 36 is rotatably connected to the bottom of the atomizer 2, a plugging plate 37 is rotatably connected to the bottom of the arc plate 34, a first spring 38 is sleeved at the rotatable connection between the plugging plate 37 and the arc plate 34, and the side wall of the plugging plate 37 is in contact with the partition 310.

[0019] A first slide plate 311 is slidably connected to the outer wall of the partition 310, and first tooth plates 312 are fixedly connected to both sides of the outer wall of the first slide plate 311. A second tooth plate 313 is slidably connected to the inside of the fan wheel 39, and a second spring 314 is fixedly connected between the second tooth plate 313 and the fan wheel 39. A second gear 315 is meshed between the second tooth plate 313 and the first tooth plate 312, and the second gear 315 is rotatably connected to the inside of the fan wheel 39.

[0020] The bottom of the first slide plate 311 is provided with serrations, and the second tooth plate 313 protrudes from the outside of the impeller 39 when not squeezed. When the second tooth plate 313 protrudes from the outside of the impeller 39, the first slide plate 311 is located inside the impeller 39, and the arc plate 34 is attached to the outer wall of the atomizer 2. After the plug plate 37 is flipped over, it is coplanar with the outer wall of the arc plate 34.

[0021] When the embodiment of the present invention is actually used: the bracket 1 is connected to an external driving device, the driving device pushes the bracket 1 to move forward on the ground, and the steam inside the atomizer 2 is discharged downward through the air outlet at the bottom thereof. When moving, the sleeve 61 drives the fan wheel 39 and the partition 310 to rotate through the first transmission belt 4. The partition 310 drives the plugging plate 37 to move during the rotation. During the movement of the plugging plate 37, the two arc plates 34 are relatively close to each other through the meshing of the arc 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 to prevent the air outlet below the atomizer 2 from being on the partition 31. 0The problem of leakage during rotation is ensured, and the efficient use of drug vapor is avoided to prevent the drug vapor from volatilizing to the outside due to sealing problems. When the impeller 39 rotates to the arc plates 34 on both sides are closed, the plugging plate 37 cannot continue to move under the push of the partition 310, so the plugging plate 37 will rotate on the arc plate 34 and cause the first spring 38 to twist to generate torque. When the plugging plate 37 is flipped to be coplanar with the arc plate 34, the stretched plugging plate 37 elastically contracts and drives the arc plate 34 and the plugging plate 37 to move away from each other. The plugging plate 37 is no longer blocked by the partition 310 and returns to a state perpendicular to the arc plate 34, and fits with the next partition 310.

[0022] When the second tooth plate 313 on the side wall of the impeller 39 contacts the soil, the second tooth plate 313 will slide inside the impeller 39 toward the axis of the impeller 39 under the influence of the rotation of the impeller 39. When the second tooth plate 313 slides inside the impeller 39, the second spring 314 will be stretched and elastically extended. In the process of the second tooth plate 313 sliding inside the impeller 39, it will drive the first slide plate 311 to extend to the outside of the impeller 39 through the second gear 315 and the first tooth plate 312. The first slide plate 311 extending outward from the inside of the impeller 39 will penetrate downward into the soil, thereby blocking the compartment formed by the partition 310 inside the impeller 39 from the outside, so that the drug vapor emitted by the nebulizer 2 can effectively act on the soil below the nebulizer 2, avoiding the emission of steam from the inside of the impeller 39 due to external factors, thereby increasing the soil control effect during fumigation.

[0023] See also Figures 7 to 9A combing assembly 6 is provided at the bottom of the bracket 1. The combing assembly 6 includes a first round rod 64 fixedly connected to the bottom of the bracket 1. The side wall of the first round rod 64 is rotatably connected to a third gear 65. The outer wall of the first round rod 64 is rotatably connected to a sleeve 66. The outer wall of the sleeve 66 is fixedly connected to a combing frame 610 distributed in an annular array. A conical plate 611 is fixedly connected between the plurality of combing frames 610 and located on the outer wall of the sleeve 66. The outer wall of the conical plate 611 is fixedly connected to a second gear ring 67 distributed in an annular array on the side away from the bracket 1. The second gear ring The ring 67 is meshed with the third gear 65, and a circular plate 68 is fixedly connected to the outer wall of the sleeve 66 and located on the side of the second gear ring 67 close to the bracket 1. The outer wall of the circular plate 68 is in contact with the third gear 65, and a fourth spring 69 is fixedly connected to the side of the circular plate 68 close to the bracket 1. Both ends of the first round rod 64 are rotatably connected to the sleeve 61, and the inner wall of the sleeve 61 is fixedly connected to the first gear ring 62 in a circular array. A cover plate 63 is installed on the side of the sleeve 61 close to the bracket 1, and the cover plate 63 is fixedly connected to the end of the fourth spring 69 away from the circular plate 68.

[0024] The outer wall of the sleeve 61 is distributed in an annular array and fixedly connected with convex teeth, the length of the convex teeth is twice that of the combing frame 610, a baffle is provided on the side of the combing 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, the outer wall of the circular plate 68 is distributed in an annular array and fixedly connected with helical teeth, a first transmission belt 4 is transmission-connected between the outer wall of the impeller 39 and the sleeve 61, a second transmission belt 5 is transmission-connected between the transmission shaft 73 and the outer wall of the impeller 39, the third gear 65 is respectively meshed with the second gear ring 67 and the first gear ring 62, and the transmission ratio of the second gear ring 67 and the first gear ring 62 is three to one.

[0025] In actual application of the embodiment of the present invention: when the equipment is used, the convex teeth on the outer wall of the sleeve 61 will penetrate into the soil. As the bracket 1 moves as a whole, the sleeve 61 will rotate. During the rotation process, the sleeve 61 will drive the sleeve 66 to rotate at a differential speed through the meshing of the first toothed ring 62 on its inner wall with the third gear 65, and the meshing of the third gear 65 with the second toothed ring 67. During the rotation process, the sleeve 66 will loosen the soil to be fumigated through the combing frame 610 to prevent the soil surface from solidifying and agglomerating and affecting the fumigation effect. During the rotation of the combing frame 610, the clods and stones in the soil will be covered by the baffle on the combing frame 610. The sticky clods of earth and stones are blocked and lifted out of the soil. When the sticky clods of earth and stones rotate to the top of the sleeve 66, they will fall down on 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 sticky clods of earth and stones will roll down on the inclined surface of the conical plate 611 to the side of the conical plate 611 close to the sleeve 61, and are arranged in a linear shape on the soil, which is convenient for the staff to collect and process the clods of earth and stones in the soil, and at the same time separate the sticky clods of earth and stones from the loose soil, which 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.

[0026] See also Fig.10 A leveling assembly 7 is provided at the bottom of the bracket 1, and the leveling assembly 7 includes a second round rod 71 fixedly connected to the bottom of the bracket 1, and both ends of the second round rod 71 are symmetrically rotatably connected to the first bevel gear 72, and the first bevel gear 72 is fixedly connected to the transmission shaft 73 on the side away from the bracket 1. The outer wall of the second round rod 71 is distributed in a linear array and fixedly connected to the second slide plate 74, and the outer wall of the second slide plate 74 is rotatably connected to the double-threaded rod 75, and the top of the double-threaded rod 75 is fixedly connected to the second bevel gear 76, and the second bevel gear 76 is meshed with the first bevel gear 72, and the outer wall of the double-threaded rod 75 is slidably connected to the pressure plate 77, and the side of the pressure plate 77 close to the fan wheel 39 is an upwardly raised angle.

[0027] When the embodiment of the present invention is actually used: when the impeller 39 is rotated, 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 process, the first bevel gear 72 will drive the double-threaded rod 75 meshing therewith to rotate together. The rotation of the double-threaded rod 75 drives the pressure plate 77 to slide back and forth up and down inside the second slide plate 74, so that the pressure plate 77 can beat and level the soil below it, making the top of the soil more compact, making it difficult for steam to escape upward through the soil, and extending the fumigation time of the steam inside the soil. When the second slide plate 74 slides on the soil when the equipment moves, the soil is formed into a block-shaped grid by the joint action of the first slide plate 311 and the second slide plate 74, thereby increasing the contact area between the inside of the soil and the outside world, so that the steam injected into the soil can escape outward through the notch formed after the second slide plate 74 cuts the soil. At the same time, by loosening and dividing the soil, it can be put into crop production faster in the later stage.
