Description

Technical Field

[0001] This utility model belongs to the technical field of agricultural fertilization equipment, and specifically relates to a spray irrigation device for increasing carbon and enriching rapeseed fields with organic fertilizer. Background Technology

[0002] Rapeseed varieties are mainly divided into three types: Chinese cabbage type, mustard type, and cabbage type. Among them, cabbage type rapeseed is a hybrid of Chinese cabbage type rapeseed and black mustard. It has large and thick leaves, bright yellow flowers, wide adaptability, and is one of the most important oil crops. It has a high oil content and is also an ornamental rapeseed. Ornamental rapeseed, due to its combined economic and landscape value, is mostly planted using a raised bed planting method. The raised beds are typically 15-20cm high, 25-30cm wide, and spaced 40-50cm apart. This method improves field ventilation and light penetration to optimize the landscape effect during flowering, while also enhancing soil aeration, reducing waterlogging, and providing a suitable environment for plant growth.

[0003] Ornamental rapeseed cultivation is mainly divided into four stages: seed germination, seedling stage, budding stage, flowering stage, podding stage, and maturity stage. Plant height varies significantly at each stage: during seed germination, the plant height is only 2-5 cm, primarily focused on seedling root development; during the seedling stage, the plant height gradually increases to 15-40 cm, with rapid leaf growth forming the basic plant shape; during the budding stage, the plant enters a rapid growth phase, reaching 40-60 cm in height, with thickened stems and emerging flower stalks; during the flowering stage, the plant height stabilizes at 80-120 cm, with densely packed flowers, marking the core ornamental stage; from the podding stage to maturity, the plant height remains relatively constant, with the center of gravity gradually shifting downwards to the pods. These growth characteristics and height differences at each stage necessitate differentiated requirements for the spraying location, range, and fertilizer type in fertilization equipment. For example, foliar fertilization is needed during the seedling stage to promote leaf growth; precise root fertilization is required during the budding stage to enhance stem resilience; and wide-range foliar fertilization with controlled application rates is necessary during the flowering stage to prevent shortening the flowering period.

[0004] Existing fertilization equipment integrates foliar fertilization and root fertilization to meet the needs of crop growth. For example, Chinese utility model patent (CN222193131U) discloses a fertilization device for cut flower cultivation. In this patent, the shell at the bottom of the tube is equipped with multiple second nozzles, and the first nozzles are used to fertilize the roots of the plant. The tube is connected to a horizontal pipe through a three-way reversing valve, and the horizontal pipe is equipped with multiple first nozzles, which are used for foliar fertilization of the plant.

[0005] While the aforementioned existing technologies allow for the selection of foliar or root fertilization based on actual needs, there are still issues that urgently require improvement.

[0006] In existing fertilization equipment, the vertical installation positions of the pipe and horizontal pipe are fixed and cannot be adjusted. The associated spacing adjustment mechanism can only adjust the overall spacing between the components on both sides; that is, the first nozzle for foliar fertilization and the second nozzle for root fertilization on the same side will move synchronously with the adjustment. As ornamental rapeseed grows, its stems gradually thicken, and the number of leaves increases, with the coverage area continuously expanding. When using the first nozzle for foliar fertilization, if the spacing between the upper two first nozzles is increased to accommodate the leaf distribution, it will cause the lower two second nozzles to move outwards synchronously. At this time, the second nozzles are very likely to collide with the thick stems or unfolded leaves of the rapeseed, damaging the plant and affecting its normal growth. Conversely, if the spacing between the two second nozzles is reduced to avoid collisions, the spacing between the upper first nozzles will also decrease, limiting the spraying range of the first nozzles and thus affecting the efficiency of foliar fertilization. Utility Model Content

[0007] The purpose of this utility model is to provide a rapeseed field organic fertilizer sprinkler irrigation carbon-enhancing and fertilization device, which aims to solve the problems existing in the prior art mentioned above.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A rapeseed field organic fertilizer sprinkler irrigation carbon enrichment and fertilization device includes a frame and a spraying mechanism mounted on the frame. The spraying mechanism includes a fixed seat and a mounting seat rotatably connected. A positioning mechanism is provided between the fixed seat and the mounting seat. The fixed seat is mounted on the frame. A three-way reversing valve is provided in the mounting seat. A first straight pipe and a second straight pipe connected to the three-way reversing valve are respectively provided on opposite sides of the mounting seat. A nozzle for foliar spraying is provided at the end of the first straight pipe, and a spray pipe for root irrigation is provided at the end of the second straight pipe. Rotating the mounting seat allows switching between the nozzle and the spray pipe.

[0009] Furthermore, the fixing seat has an annular groove in the middle, and threaded holes are provided on opposite sides of the annular groove. The mounting seat includes a fixing part and a connecting part that is rotatably sleeved in the annular groove. Through holes are provided on both sides of the connecting part, and the aligned through holes and threaded holes are fixed by screws.

[0010] Furthermore, the second straight pipe is connected to two nozzles at its end, and the nozzles are provided with curved sections, with the two nozzles forming an "eight" shape.

[0011] Furthermore, an adjustment mechanism is provided between the second straight pipe and the nozzle. The adjustment mechanism includes a U-shaped plate and a sliding plate. The second straight pipe is perpendicularly connected to the back plate of the U-shaped plate. The back plate is provided with a strip-shaped slot. The inner sides of the parallel side plates on both sides of the back plate are provided with sliding grooves. The two ends of the sliding plate are respectively slidably engaged with the sliding grooves on both sides. The sliding plate is provided with connecting holes that are aligned vertically with the strip-shaped slot. The strip-shaped slot and the connecting holes are fixed by bolts. The upper part of the nozzle passes through the sliding plate. The nozzle and the second straight pipe are connected by a corrugated pipe.

[0012] Furthermore, a flexible hose is fitted to the end of the nozzle.

[0013] Furthermore, the frame includes a support rod for connecting the fixed seat. The support rod has a first fixing hole that runs vertically through the frame. The first fixing holes are evenly distributed along the axial direction of the support rod. The fixed seat has second fixing holes on both sides of the annular groove. The first fixing holes and the second fixing holes that are aligned and connected are fixed by bolts. The distance between adjacent first fixing holes is the same as the distance between the second fixing holes on both sides of the fixed seat.

[0014] Compared with the shortcomings and deficiencies of the prior art, the present invention has the following beneficial effects.

[0015] 1. The organic fertilizer sprinkler irrigation carbon-enhancing and fertilization equipment for rapeseed fields provided by this utility model has a first straight pipe connecting to the foliar fertilization nozzle and a second straight pipe connecting to the root irrigation nozzle respectively set on opposite sides of the mounting base. The two pipes can be independently switched in operation mode by relying on the flipping function of the mounting base. When using the nozzle for foliar fertilization, the nozzle can be directly flipped to the upper non-operation position, avoiding the rapeseed plants in terms of spatial layout, thereby avoiding the risk of collision between the nozzle and the rapeseed stems and leaves.

[0016] 2. The spacing between nozzles can be flexibly adjusted by moving the fixed base; while the spacing between adjacent spray pipes can be precisely controlled by the adjustment mechanism. This ensures both the flexibility of the nozzle spraying range during foliar fertilization and the accuracy of the spray pipe spacing during root fertilization, improving the ease of use of this organic fertilizer sprinkler irrigation carbon enrichment and fertilization equipment, and adapting it to the fertilization needs of rapeseed throughout its entire growth cycle.

[0017] 3. The nozzle end is fitted with a flexible hose, which can cushion the impact and reduce the risk of damage to the rapeseed plant even if it accidentally comes into contact with the rapeseed stem during root fertilization. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Reference Figure 1 and Figure 2 This utility model discloses an organic fertilizer sprinkler irrigation carbon enrichment and fertilization equipment for rapeseed fields, including a frame 100 and multiple spraying mechanisms 200 installed side by side on the frame. The frame 100 provides support for the spraying mechanisms 200 and is also used to connect to external mobile equipment, thereby facilitating the mobile application of the organic fertilizer sprinkler irrigation carbon enrichment and fertilization equipment in rapeseed fields.

[0027] External mobile equipment can be selected from 15-30 horsepower models, such as the Lovol M300-E. During operation, the wheels travel along the furrows and are fixed to the rear suspension frame of the tractor via the connecting plate 110 of the frame 100. The hydraulic lifting system of the tractor can directly drive the frame 100 to lift and lower as a whole, thereby adjusting the height of the support rod 120 to suit the plant height during the seed germination, seedling, and budding stages of ornamental rapeseed.

[0028] The frame 100 adopts a frame structure, including multiple parallel support rods 120. The support rods 120 are connected by connecting rods, and the support rods 120 and connecting rods can be fixed by welding. The support rods 120 on one side are used to install the spraying mechanism 200, and the support rods 120 on the other side are welded with connecting plates 110. The connecting plates 110 are used to connect with external mobile equipment, and the connection method can be bolt fixing. Reference Figures 3-6 The spraying mechanism 200 includes a fixed seat 210 and a mounting seat 220 that are rotatably fitted together. The mounting seat includes a connecting part 221 and a fixing part 222. The connecting part 221 is a sleeve structure. The fixed seat 210 has an annular groove 211 in the middle, which extends along its axial direction. The connecting part 221 is rotatably fitted onto the annular groove 211. Threaded holes 212 are provided on opposite sides of the annular groove 211. Through holes 224 are provided on both sides of the connecting part 221. Rotating the connecting part 221 makes the through holes 224 and the threaded holes 212 aligned and connected. A screw passes through the through holes 224 and is threadedly connected to the threaded holes 212, thereby fixing the position of the mounting seat 220 on the fixed seat 210 and forming a reliable positioning structure.

[0029] The fixed base 210 has two through-holes 213 on both sides of the annular groove 211. Correspondingly, the support rod 120 has a first through-hole 121. The first through-holes 121 are evenly distributed along the axial direction of the support rod 120, and the spacing between adjacent first through-holes 121 is the same as the spacing between the second through-holes 213 on both sides of the fixed base 210. The fixed base 210 is sleeved on the support rod 120 and slides with it. Moving the fixed base 210 aligns the first through-holes 121 with the second through-holes 213 and fixes them with bolts, thereby fixing the fixed base 210 to the support rod 120 of the frame 100. The bolt fixation facilitates the adjustment of the distance between the spraying mechanisms 200.

[0030] The fixing part 222 is equipped with a three-way reversing valve 223. One end of the three-way reversing valve 223 is connected to an external organic fertilizer delivery pipeline. Of the two opposite ends, one end is connected to a first straight pipe 230, and the other end is connected to a second straight pipe 250. A nozzle 240 is installed at the end of the first straight pipe 230. The nozzle 240 adopts an atomizing nozzle structure, which can evenly atomize the organic fertilizer and spray it onto the surface of the rapeseed leaves, improving the leaf absorption efficiency and avoiding impact damage to the leaves due to excessive water flow. The end of the second straight pipe 250 is connected to two sets of spray pipes 260. The spray pipes 260 are used to water fertilizer to the rapeseed roots. The spray pipes 260 have a bend 262, so that the end of the pipe is tilted downward. The two spray pipes 260 are in a figure-eight shape, which facilitates simultaneous watering of fertilizer to the roots of plants on both sides, ensuring that the organic fertilizer can be accurately watered into the soil around the roots, reducing fertilizer waste and improving the root absorption effect. The organic fertilizer can be switched to be transported to the first straight pipe 230 or the second straight pipe 250 by controlling the three-way reversing valve 223.

[0031] In one embodiment, a flexible hose 261 is fitted onto the end of the nozzle 260. The flexible hose 261 is made of wear-resistant and corrosion-resistant rubber material. On the one hand, this can prevent the end of the nozzle 260 from directly contacting the soil or crops and causing wear. On the other hand, when the flexible hose comes into contact with the rapeseed stem, it can reduce the risk of rapeseed damage.

[0032] In one embodiment, an adjustment mechanism 270 is provided between the second straight pipe 250 and the nozzle 260. The adjustment mechanism 270 includes a U-shaped plate 271 and a sliding plate 273. The back plate of the U-shaped plate 271 is perpendicularly connected to the second straight pipe 250 by welding or bolting to ensure connection strength. The back plate has strip-shaped slots 272 on both sides of the second straight pipe 250; grooves 275 are provided on the inner sides of the parallel side plates on both sides of the back plate, extending horizontally, and the length of the grooves 275 matches the length of the strip-shaped slots 272. The two ends of the slide plate 273 are respectively slidably engaged with the two side slide grooves 275, allowing the slide plate 273 to slide stably along the slide grooves 275. The slide plate 273 is provided with connecting holes 274 that align vertically with the strip-shaped slot holes 272. The position of the slide plate is fixed by bolts passing through the strip-shaped slot holes and connecting holes in sequence. The upper part of the nozzle 260 passes through the slide plate 273 and is fixedly connected to the slide plate 273. The nozzle 260 is connected to the second straight pipe 250 through a corrugated pipe 263. When it is necessary to adjust the position of the slide plate 273, the bolts are loosened, the slide plate 273 is pushed to the appropriate position, and then the bolts are passed through the strip-shaped slot holes 272 and connecting holes 274 and tightened to lock the position of the slide plate 273. The corrugated pipe 263 has good extensibility and sealing performance. When the slide plate 273 moves the nozzle 260 to adjust the spacing, it can extend and retract synchronously to adapt to the positional changes of the nozzle 260.

[0033] The working process of the organic fertilizer sprinkler irrigation carbon enrichment and fertilization equipment in rapeseed fields: The foliar spraying mode is suitable for the seedling and flowering stages of ornamental rapeseed.

[0034] Loosen the screw between the fixing seat 210 and the mounting seat 220, rotate the mounting seat 220 so that the first straight pipe 230 and the nozzle 240 face downwards toward the rapeseed leaves, and after the through hole 224 is aligned with the threaded hole 212, tighten the screw to fix the mounting seat 220.

[0035] Move the fixed base 210 along the support rod 120, adjust the spacing between adjacent spraying mechanisms 200 according to the spread of rapeseed leaves, and then fix the first fixing hole 121 and the second fixing hole 213 with bolts.

[0036] Start the traction equipment and drive it at a constant speed of 0.8-1.2 km / h along the furrow. At the same time, turn on the external delivery pump to deliver water-soluble organic fertilizer through the pipeline to the three-way reversing valve 223. Control the three-way reversing valve 223 to allow the organic fertilizer to enter the first straight pipe 230 and be evenly sprayed on the leaf surface through the nozzle 240 to complete the foliar fertilization.

[0037] Based on the current height adjustment traction device lifting structure for ornamental rapeseed plants, during the seedling stage, the height of the support rod 120 of the frame 100 is lowered to 30-50cm through the tractor hydraulic system; during the flowering stage, the height of the support rod 120 is raised to 90-130cm to ensure that the spray nozzle 240 maintains a spraying distance of 15-20cm from the leaves.

[0038] The root irrigation method is suitable for the budding stage of ornamental rapeseed.

[0039] The tractor's hydraulic system allows the hose 261 at the end of the nozzle 260 to be close to the soil on the ridge, while the frame 100 is positioned above the top of the ornamental rapeseed plants.

[0040] Loosen the screw and rotate the mounting base 220 to flip the nozzle 240 to the upper non-working position, with the spray pipe 260 facing the rapeseed roots, and align and fix the mounting base 220.

[0041] Loosen the bolts in the adjustment mechanism 270, push the slide plate 273 to move along the slide groove 275, and drive the nozzle 260 to adjust the spacing so that the hoses 261 of the two nozzles 260 correspond to the roots on both sides 10-15cm apart. After adjustment, tighten the bolts to fix the slide plate 273. At this time, the corrugated pipe 263 moves synchronously with the nozzle to ensure the sealing of fertilizer delivery.

[0042] The traction equipment travels at a constant speed, and the delivery pump is turned on to deliver organic fertilizer to the three-way reversing valve 223. The three-way reversing valve is controlled to allow the organic fertilizer to enter the second straight pipe 250, and then be irrigated into the soil around the roots through the spray pipe 260 and the hose 261. The hose 261 can avoid collision with the stem through flexible deformation, thus protecting the plant's growth.

[0043] During the rapeseed seed stage to the budding stage, the plants are short, there is ample space for field operations, and the cost of using traditional agricultural machinery is relatively lower. Therefore, by using traditional agricultural machinery to drive this organic fertilizer sprinkler irrigation carbon-enhancing and fertilization equipment, in conjunction with the frame 100 and the external mobile equipment, the equipment can move at a uniform speed along the rows in the rapeseed field, ensuring even fertilization. At the same time, since the spraying mechanism 200 can switch between two fertilization modes by rotating the mounting base 220, and the spacing of the spray nozzles 260 can be adjusted independently, the problem of mutual interference between nozzle adjustments in existing technologies is avoided. In addition, when applying foliar fertilizer, the spray nozzles 260 are rotated to a non-operating position with the mounting base 220, effectively preventing the spray nozzles 260 from colliding with the rapeseed stems and leaves, thus protecting the growth of the rapeseed plants. Once rapeseed enters its flowering period, due to the height of the plants, traditional traction equipment cannot move and fertilize normally in the field. Plant protection drones or other fertilization methods can be chosen. Although plant protection drones are more expensive to use than traditional agricultural machinery, the plants are no longer in a suitable condition for traditional agricultural machinery to enter the field. Therefore, switching to plant protection drones for fertilization can avoid damage to the rapeseed plants and continue to complete subsequent fertilization operations.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
