[0002] The group has developed and obtained a series of crop SOD yield-increasing patent technologies, and the main means is to spray special reagents such as trace element fertilizer and SOD-producing bacterial liquid to crops.

The SOD-producing bacteria can be mixed with fertilizers, other bacteria, even pre-fermented to obtain different bacterial liquid reagents, and improving the utilization rate of reagents is an important problem.

[0003] The existing spraying device is designed more conventionally. The SOD-producing Bacillus cereus liquid is sprayed on the plant to facilitate the absorption of the plant. The spraying device is located above the plant, and the liquid falls on the leaves of the plant from above.

[0036] The SOD-producing bacteria sprayed by the present application can be Bacillus cereus, and the bacterial solution can also contain other Bacillus cereus to form a complex bacterial agent. The bacterial solution can be a mixture of bacteria and water, or a spraying solution obtained by pre-fermentation and even from the pile spraying. The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0037] The present application discloses a spraying device, such as Figures 1-11As shown, the system includes a fixed base 100, a connecting frame 300, a first drive mechanism 600, a second drive mechanism 700, multiple fixed arms 900, multiple wheeled spraying mechanisms 400, and multiple root injection mechanisms 500. The fixed base 100 is fixedly connected to the agricultural machinery. Multiple lifting hydraulic cylinders 200 are arranged between the connecting frame 300 and the fixed base 100, and these lifting hydraulic cylinders 200 are spaced laterally along the fixed base 100. The multiple fixed arms 900 are mounted on the connecting frame 300 at lateral intervals, and each fixed arm 900 is slidably connected to the connecting frame 300. A wheeled spraying mechanism 400 and a root injection mechanism 500 are connected to each fixed arm 900, and each root injection mechanism 500 is located at a corresponding furrow. Each driving wheeled spraying mechanism 400 is drively connected to the first drive mechanism 600, and the first drive mechanism 600 drives the wheeled spraying mechanism 400 to rotate. The second drive mechanism 700 of the present invention is mounted on the connecting frame 300. The second drive mechanism 700 is connected to each fixed arm 900 in a transmission manner. The function of the second drive mechanism 700 is to drive the fixed arms 900 to move closer or further apart from each other.The working principle and advantages of this invention are as follows: This invention is mainly aimed at the vigorous growth period of crops such as vegetables. During this period, the stems and roots of the crops are covered by their branches and leaves. By adjusting the height of the connecting frame 300 using the lifting hydraulic cylinder 200, the wheel-type spraying mechanism 400 is positioned vertically between two planting ridges, with its lower end close to the ground and its upper end extending a certain distance beyond the plant. The lower end of the root injection mechanism 500 is inserted into the soil between the two planting ridges, with its sides extending into the soil close to the roots of the plants on both planting ridges. Then, a portion of the bacterial solution is pumped into each wheel-type spraying mechanism 400, and the bacterial solution is sprayed onto the plants on both sides by the wheel-type spraying mechanism 400. Furthermore, the bacterial solution is sprayed while the wheel-type spraying mechanism 400 rotates under the drive of the first drive mechanism 600, ensuring the uniformity and sufficiency of the bacterial solution spraying. Another portion of the bacterial solution is evenly pumped... The solution is injected into each root system injection mechanism 500. As the agricultural machinery moves, the lower part of each root system injection mechanism 500 travels within the soil. During this movement, the solution is evenly injected into the soil through the lower part of the root system injection mechanism 500, and gets close to the plant's roots, ensuring that the plant roots absorb the bacterial solution. This achieves comprehensive spraying of the bacterial solution onto the plant. Furthermore, the invention controls the second drive mechanism 700, which drives each fixed arm 900 to move laterally, adjusting the spacing between the fixed arms 900. This allows the gaps between adjacent wheeled spraying mechanisms 400 to adapt to planting ridges of different widths, and the gaps between adjacent root system injection mechanisms 500 to adapt to planting ridges of different widths. In summary, the invention can perform three-dimensional spraying of bacterial solution onto crops, allowing the leaves, stems, and roots of the plants to fully absorb the bacterial solution, thereby enriching the crops with SOD.

[0038] As a preferred embodiment of the present invention, such as Figure 1 , 3As shown in Figure 6, the fixed arm 900 includes an arm body 901. A sliding seat 902 is constructed at one end of the arm body 901 near the agricultural machinery, and a connector 903 is hinged to the other end of the arm body 901. A transverse guide rail 301 is constructed on the connecting frame 300, and the sliding seat 902 is mounted on the transverse guide rail 301 and can slide along the transverse guide rail 301. The connector 903 is connected to the upper end of the connecting arm 1000, thereby realizing the hinge connection between the fixed arm 900 and the connecting arm 1000. In this embodiment, the wheel-type spraying mechanism 400 is mounted at the end of the connecting arm 1000 away from the fixed arm 900. In this embodiment, an inclined hydraulic cylinder 800 is hinged between the connecting arm 1000 and the corresponding fixed arm 900. By controlling the movement of the inclined hydraulic cylinder 800, the connecting arm 1000 is driven to move, thereby changing the angle between the connecting arm 1000 and the fixed arm 900. This changes the vertical distance between the fixed arm 900 and the wheel-type spraying mechanism 400. Then, by adjusting the movement of the lifting hydraulic cylinder 200, the wheel-type spraying mechanism 400 is positioned close to the soil, ensuring that the fixed arm 900 is higher than the plant. Therefore, this embodiment can adapt to plants of different heights, allowing for the application of bacterial solution to plants of the same variety at different stages, as well as to plants of different varieties and heights. When adjusting the angles of the fixed arm 900 and the connecting arm 1000, the spraying range of the wheel-type spraying mechanism 400 is also adjusted accordingly, ensuring thorough spraying of the plants. In this embodiment, a rotating rod 1100 is rotatably connected to one end of the connecting arm 1000 near the fixed arm 900. The rotating rod 1100 is connected to the wheel-type spraying mechanism 400 via a transmission mechanism. Connecting flanges 1101 are constructed at both ends of the rotating rod 1100. The rotating rods 1100 on adjacent connecting arms 1000 are connected by telescopic rods 603. The telescopic rod 603 consists of two interlocking rods, one of which has an interlocking cavity with a regular polygonal cross-section, and the other has an interlocking portion with a regular polygonal cross-section. The interlocking portion is inserted into the interlocking cavity. Thus, the telescopic rod 603 achieves telescopic extension under the drive of the second drive mechanism 700, and the two rods of the telescopic rod 603 achieve synchronous rotation under the drive of the first drive mechanism 600. The first drive mechanism 600 in this embodiment includes a first drive motor 601, which is mounted on the outermost connecting arm 1000. The first drive motor 601 is connected to the rotating rod 1100 on the connecting arm 1000 via a gearbox 602. The first drive motor 601 drives each rotating rod 1100 and the telescopic rod 603 to rotate via the gearbox 602. The rotating rod 1100 drives the wheeled spraying mechanism 400 to rotate via a transmission mechanism, thereby improving the uniformity of bacterial liquid spraying.

[0039] As a preferred embodiment of the present invention, such as Figures 7-8As shown, the wheel-type spray mechanism 400 includes an assembly rod 401, an assembly sleeve 403, an adapter cylinder 405, and multiple atomizing spray pipes 406. The assembly rod 401 is fixedly connected to the end of the connecting arm 1000 away from the fixed arm 900, and has a liquid guiding channel. The assembly sleeve 403 is fitted onto the assembly rod 401 and is rotatably connected to it. An adapter cylinder 405 is constructed on the assembly sleeve 403. A connecting hole 402 is provided on the assembly rod 401, and the adapter cylinder 405 is fitted onto the assembly rod 401 at the position of the connecting hole 402, so that the inner cavity of the adapter cylinder 405 is interconnected with the liquid guiding channel through the connecting hole 402. In this embodiment, the multiple atomizing spray pipes 406 are evenly connected to the adapter cylinder 405 along its circumference, and each of these atomizing spray pipes 406 is connected to the inner cavity of the adapter cylinder 405. One end of the assembly rod 401 is connected to a first injection pipe, which communicates with a liquid guiding channel. The pumped bacterial solution enters the liquid guiding channel through the first injection pipe, and then is sprayed onto the plant by the atomizing spray pipe 406. The transmission mechanism in this embodiment includes a first sprocket 404, a second sprocket 1102, and a first transmission chain 1103. The first sprocket 404 is mounted on the assembly rod 403, and the second sprocket 1102 is mounted on the rotating rod 1100. The first sprocket 404 and the second sprocket 1102 are connected by the first transmission chain 1103. The first drive motor 601 drives the rotating rod 1100 to rotate, which in turn causes the second sprocket 1102 to rotate. The second sprocket 1102 drives the first sprocket 404 to rotate through the first transmission chain 1103. In this way, the first sprocket 404 drives the assembly 403 to rotate, which in turn drives the atomizing spray pipe 406 to rotate along the assembly rod 401. This enables the atomizing spray pipe 406 to rotate while spraying the bacterial solution, so that the bacterial solution is fully sprayed on the above-ground parts of the plant except for the roots.

[0040] In a preferred embodiment of the present invention, to accommodate crops of different plant heights, the atomizing spray pipe 406 employs a method of adjusting its length according to the bacterial liquid pressure. Specifically, as shown in... Figures 9-10As shown, the atomizing spray pipe 406 includes a base pipe 4061 and at least one extension pipe. Multiple spray holes are provided on the base pipe 4061 and each extension pipe. The base pipe 4061 is connected to the adapter cylinder 405. When there is only one extension pipe, one end of the extension pipe is inserted into the end of the base pipe 4061 furthest from the adapter cylinder 405. A first spring 4064 is installed inside the base pipe 4061, with both ends connected to the base pipe 4061 and the extension pipe, respectively. Thus, as the pressure gradually increases, the extension pipe gradually extends out of the base pipe 4061, increasing the length of the atomizing spray pipe 406 and thus improving the spraying range of the bacterial solution. As the pressure gradually decreases, the extension pipe gradually extends into the base pipe 4061 under the action of the first spring 4064, shortening the length of the atomizing spray pipe 406. When there are multiple extension tubes, their diameters decrease sequentially, and they are interlocked. The extension tube with the largest diameter is inserted into the base tube 4061. The extension tube with the largest diameter is connected to the base tube 4061 via a first spring 4064. The two interlocked extension tubes are connected by a second spring 4066. This embodiment uses two extension tubes as an example. These two extension tubes are the first extension tube 4063 and the second extension tube 4065. The diameter of the first extension tube 4063 is larger than that of the second extension tube 4065. The first extension tube 4063 is inserted into the base tube 4061 and connected to the base tube 4061 via the first spring 4064. The second extension tube 4065 is inserted into the first extension tube 4063. A second spring 4066 is installed inside the first extension tube 4063 and is connected to the insertion end of the second extension tube 4065. As the pressure of the bacterial solution gradually increases, the first extension tube 4063 and the second extension tube 4065 gradually extend outward, thereby increasing the spraying range of the atomizing spray tube 406. As the pressure decreases, the first extension tube 4063 and the second extension tube 4065 gradually retract under the action of the first spring 4064 and the second spring 4066, thereby reducing the spraying range of the atomizing spray tube 406. Moreover, in this embodiment, even when the atomizing spray tube 406 is shortened or extended to its limit, the pressure of the bacterial solution is sufficient to atomize and spray the bacterial solution from the spray hole, thus achieving the spraying operation of the atomized bacterial solution on the plants.

[0041] In a preferred embodiment of the present invention, to adjust the spraying direction of the bacterial solution by the wheel-type spraying mechanism 400, the spray holes of the atomizing spray pipe 406 are located on the same side of the atomizing spray pipe 406. This allows the wheel-type spraying mechanism 400 to spray the plant on one side in a cylindrical, gradually expanding, or gradually contracting frustum shape, thereby adjusting the spraying range of the bacterial solution and enabling spraying of bacterial solution to plants of different heights. To achieve the conversion between these three shapes, the measures taken include, for example... Figures 7-8As shown, one end of each atomizing spray pipe 406 is hinged to the adapter cylinder 405, and the atomizing spray pipe 406 is connected to the inner cavity of the adapter cylinder 405 through the hose 4062. An adjusting sleeve 407 is movably connected to the mounting set 403. The adjusting sleeve 407 is fixed to the mounting set 403 by positioning bolts. Multiple connecting rods 408 are evenly arranged on the adjusting sleeve 407 along its circumference. The two ends of each connecting rod 408 are respectively hinged to the adjusting sleeve 407 and the corresponding atomizing spray pipe 406. In this embodiment, by adjusting the position of the adjusting sleeve 407 on the mounting sleeve 403, and then fixing the mounting sleeve 403 and the adjusting sleeve 407 with the positioning bolts, the connecting rod 408 drives the atomizing spray pipe 406 to move. The atomizing spray pipe 406 moves along the hinge point between it and the adapter cylinder 405, causing the angle between the axis of the atomizing spray pipe 406 and the axis of the adapter cylinder 405 to change, thereby realizing that the bacterial liquid sprayed by the wheel spraying mechanism 400 has different forms.

[0042] As a preferred embodiment of the present invention, such as Figure 3 As shown, the second drive mechanism 700 includes a second drive motor 701 and a transmission screw 702. The second drive motor 701 is mounted on the connecting frame 300, and a connecting seat 705 is mounted on each fixed arm 900. The transmission screw 702 is connected to each connecting seat 705. The threads constructed on the transmission screw 702 include two sets of symmetrical first threads 703 and two sets of symmetrical second threads 704. The two sets of second threads 704 are located between the two sets of first threads 703, and the pitch of the first threads 703 is greater than the pitch of the second threads 704. The rotation directions of the two sets of first threads 703 are opposite, and the rotation directions of the two sets of second threads 704 are opposite. The working principle of this embodiment is as follows: When it is necessary to adjust the gap between the fixed arms 900 so that the wheel spraying mechanism 400 and the root injection mechanism 500 can adapt to different ridge spacings, the measures taken are to drive the second drive motor 701 so that the second drive motor 701 drives the transmission screw 702 to rotate in the forward or reverse direction. Due to the setting of the first thread 703 and the second thread 704, the movement speed of the connecting seat 705 connected to the first thread 703 is greater than the movement speed of the connecting seat 705 connected to the second thread 704. In this way, the spacing between adjacent fixed arms 900 is the same after adjustment, so as to adapt to different ridge spacings.

[0043] As a preferred embodiment of the present invention, such as Figure 5 , 11As shown, the root injection mechanism 500 includes a first vertical pipe 501, a second vertical pipe 502, a plow-shaped injection component, and a pressing assembly. The upper end of the first vertical pipe 501 is connected to a fixed arm 900, and a second injection pipe is connected to the first vertical pipe 501. Pumped bacterial solution enters the first vertical pipe 501 through the second injection pipe. In this embodiment, the upper end of the second vertical pipe 502 is inserted into the lower end of the first vertical pipe 501, and the lower end of the second vertical pipe 502 is connected to the upper end of the plow-shaped injection component. The pressing assembly is installed at the lower part of the second vertical pipe 502, and is located behind the plow-shaped injection component (on the side of the plow-shaped injection component furthest from the agricultural machinery). The specific structure of the plow-shaped liquid injection device in this embodiment is as follows: the plow-shaped liquid injection device includes a distribution part 503 and at least one plow blade 505. The distribution part 503 is detachably connected to the lower end of the second vertical pipe 502. Two plow blades 505 are generally used, symmetrically connected to the lower end of the distribution part 503. Each plow blade 505 is inclined downwards and extends outwards. A plow tip 504 is constructed at the front end of each plow blade 505. The distribution part 503 has a liquid cavity communicating with the second vertical pipe 502, and the plow blade 505 has a spraying cavity communicating with the liquid cavity. Multiple injection holes are respectively opened on the upper and lower end faces of each plow blade 505. The working principle of this embodiment is as follows: as the agricultural machinery moves, the plow blade 505 travels through the plow tip 504 into the soil close to the root system. During this process, the bacterial solution passes sequentially through the first vertical pipe 501, the second vertical pipe 502, the liquid cavity, and the spraying cavity, and then is injected into the soil through the injection holes, thereby supplying the plant's root system. The purpose of the compaction assembly in this embodiment is to roll and compact the soil loosened by the plow blades 505, restoring the soil to its original compaction level. The compaction assembly includes a connecting plate 506 connected to the second vertical pipe 502. A vertical rod 507 is movably connected to the connecting plate 506. A pressure roller seat 510 is fixed to the lower end of the vertical rod 507, and a compaction roller 511 is rotatably connected to the pressure roller seat 510. The compaction roller 511 can be cylindrical or have a shape where the radial length increases from both ends towards the center. Both shapes are designed to adapt to different furrow shapes, ensuring that the lower surface of the compaction roller 511 fits the furrow. In this embodiment, the upper end of the vertical rod 507 extends beyond the connecting plate 506, and a stop block 508 is constructed at the upper end of the vertical rod 507. A buffer spring 509 is fitted onto the vertical rod 507, and its upper and lower ends are fixed to the stop block 508 and the connecting plate 506, respectively. When the press roller 511 rolls the furrow surface, the buffer spring 509 remains compressed. This allows the buffer spring 509 to exert downward force on the press roller 511 through the vertical rod 507, ensuring that the press roller 511 fully rolls the furrow surface and achieves the expected density.

[0044] The present invention also discloses a spraying method using the above-mentioned spraying equipment, comprising the following steps:

[0045] S1. During the germination period of crops, this equipment needs to be reassembled, such as... Figure 12 As shown, multiple wheel-type spraying mechanisms 400 are horizontally spaced on the horizontal plate 1300, with each wheel-type spraying mechanism 400 spraying downwards. The mounting rod 401 and the mounting set 403 are fixedly connected, and the mounting set 403 is rotatably connected to the horizontal plate 1300, thereby ensuring that when the first sprocket 404 on the driving mounting set 403 rotates, the mounting rod 401 also rotates accordingly. Next, a third drive mechanism is installed on the horizontal plate 1300, which is then connected to the first sprocket 404 on each wheeled spraying mechanism 400, connecting the horizontal plate 1300 to the agricultural machinery. The third drive mechanism includes a third drive motor 1200, which is connected to the first sprocket 404 on each wheeled spraying mechanism 400 via a second transmission chain 1201, causing the wheeled spraying mechanism 400 to rotate and spray the bacterial solution onto the surface of the seedlings. Furthermore, multiple adjusting cylinders 1400 are installed on the side of the horizontal plate 1300 closest to the agricultural machinery. These adjusting cylinders 1400 are all connected to the agricultural machinery. By controlling the adjusting cylinders 1400, the height of the horizontal plate 1300 from the seedlings can be adjusted. By manually adjusting the connection angle between the adjusting cylinders 1400 and the horizontal plate 1300, the spraying angle of the wheeled spraying mechanism 400 can be adjusted. The purpose of the above operations is mainly to ensure that the bacterial solution is evenly sprayed onto the entire seedling.

[0046] S2. As the agricultural machinery moves through the field, the bacterial solution is sprayed from above onto the crop seedlings. The spraying operation is carried out in three times during the seedling stage, with an interval of 6-8 days.
