Description

Technical Field

[0001] The invention relates to the technical field of vegetable planting, and in particular to a water-saving vegetable fertilization and irrigation device and method. Background Art

[0002] With the continuous development of modern agricultural technology, agricultural automation and intelligent equipment are playing an increasingly important role in improving production efficiency, reducing labor costs and optimizing the crop growth environment, especially in the application of automated irrigation and fertilization systems in greenhouse vegetable cultivation.

[0003] The patent with the publication (announcement) number CN119452964A discloses an integrated device for pest control, irrigation and fertilization based on greenhouse vegetable cultivation. In this prior art operation, the assembly bracket cooperates with the tilt adjustment mechanism, and the main retractable bracket is slidably installed on the assembly bracket; the alignment adjustment component is connected to the main retractable bracket by power; the auxiliary retractable bracket is symmetrically arranged, and the retractable adjustment component is connected to its power. The drive component maintains power connection with the alignment adjustment component and the retractable adjustment component; the spraying component includes a nozzle, a liquid supply pipe and a scissor-type mechanism. The scissor-type mechanism is installed on the main and auxiliary retractable brackets, and the liquid supply pipe is evenly assembled on the scissor-type mechanism, and the nozzle is connected to the liquid supply pipe. It can effectively improve the production efficiency of greenhouse vegetables, reduce costs, reduce resource waste, and meet the needs of efficient, energy-saving and sustainable agricultural development.

[0004] However, the above prior art has the following technical defects: 1. This prior art irrigates and fertilizes vegetables through multiple evenly distributed nozzles, but the nozzles of the prior art are all vertically downward, so that most of the sprayed water and liquid fertilizer fall on the leaves of the vegetables themselves or on the soil far away from the roots of the vegetables. However, most nutrients and water for vegetable planting need to be absorbed from the soil by the roots. The above method will reduce the nutrients and water in the soil near the roots of the vegetables, resulting in incomplete development of the vegetable roots, affecting the quality of the finished vegetable products.

[0005] 2. In this prior art, the spray mechanism is an independent entity. During the use of the device, it is inevitable that the traveling frame itself cannot move forward due to structural damage or external objects blocking it. At this time, the spray mechanism is still in working condition. If the staff cannot find and close it in time, the spray mechanism will cause too much water or fertilizer to be sprayed on the vegetables below, resulting in waste of water or fertilizer.

[0006] Therefore, the prior art still has room for improvement in improving irrigation effects and shutting off irrigation when the device stops moving. Therefore, technical personnel in this field have proposed a device that can fertilize and irrigate the soil at the roots of vegetables and stop spraying when the device stops moving.

During the movement of the moving mechanism, the centrifugal force is used to open the through grooves on the piston seat, so that water can pass through the piston seat, and then the various nozzles can spray water. When the moving mechanism is damaged or stops moving due to obstruction by external objects, the piston seat will stop rotating. Since the centrifugal force disappears and the through grooves are closed, water cannot pass through the piston seat, and the various nozzles will stop spraying water. This can avoid the nozzles spraying too much water or fertilizer on the same position due to the staff's failure to discover in time when the device stops moving, thereby achieving the purpose of saving.

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1 - Fig.15 Embodiments of the present invention are described in detail.

[0042] The embodiment of the present application discloses a water-saving vegetable fertilization and irrigation device and method. The direction of the nozzle of the sprinkler mechanism can be changed, and during use, the nozzle can be directed toward the soil at the roots of the vegetables. In the subsequent sprinkler irrigation process, the soil at the roots of the vegetables can be fertilized and irrigated to ensure the normal development of the roots of the vegetables. A good root system provides a stable base for the plants, which helps the plants grow stronger, improves the quality of the finished vegetable products, and produces more fruits and vegetables, thereby improving economic benefits. At the same time, it can improve the overall health of the plants, thereby enhancing their resistance to diseases and insect pests.

[0043] Embodiment 1: like Figure 1-Figure 3As shown, it includes a sprinkler mechanism 1 and a mobile mechanism 2, the mobile mechanism 2 includes a shell 202 located above the sprinkler mechanism 1, two shafts 203 are rotatably installed between the inner side surfaces of the shell 202, a motor 207 is installed on the inner bottom surface of the shell 202, a first gear 205 is installed on the driving end of the motor 207, and a second gear 206 meshing with the first gear 205 is installed on the side of the shaft 203 close to the first gear 205. When the motor 207 is running, it drives the first gear 205 to rotate, and the rotating first gear 205 drives the shaft 203 to rotate through the second gear 206.

[0044] like Figure 2 and Figure 3 As shown, two tracks 201 are symmetrically arranged on the side of the shell 202, and both ends of the shaft rod 203 extend to the outside of the shell 202 and are installed with track wheels 204 on the same side track 201. Two U-shaped frames 5 are symmetrically installed on the lower side of the shell 202. The rotating shaft rod 203 drives the track wheels 204 at both ends thereof to rotate, so that it moves on the track 201, thereby driving the shell 202 to move.

[0045] like Figure 4-Figure 6 As shown, the sprinkler mechanism 1 includes a rectangular frame 101 installed on two U-shaped frames 5, and two hollow tubes 102 are symmetrically installed on the inner side of the rectangular frame 101. A plurality of slide seats 103 are slidably arranged on the two hollow tubes 102, and the slide seats 103 can slide on the hollow tubes 102, so that the position of the slide seats 103 can be adjusted according to the vertical position of the vegetables.

[0046] like Figure 7-Figure 8 As shown, two vertical plates 104 are symmetrically installed on the lower side of the slide 103, and a deflection gear 106 is rotatably installed on the side of the vertical plate 104. One end of the deflection gear 106 passes through the vertical plate 104 and is installed with an L-shaped plate 105. A deflection rack 107 meshing with the deflection gear 106 is provided on one side of the deflection gear 106. When the two deflection racks 107 descend, the meshing deflection gear 106 rotates, driving the L-shaped plate 105 to rotate, and then the two L-shaped plates 105 deflect toward the center.

[0047] like Figure 8 As shown, a sliding rod 114 is installed on the side of the vertical plate 104 on one side of the deflection rack 107, and a slider 115 fixedly connected to the deflection rack 107 is slidably arranged on the sliding rod 114. The moving deflection rack 107 drives the slider 115 to slide on the sliding rod 114, thereby enhancing the stability of the deflection rack 107 when moving.

[0048] like Figure 7-Figure 8As shown, a nozzle 110 is installed on the lower side of the L-shaped plate 105, and a three-way hose 111 is installed together at the two corresponding nozzles 110 under the slide 103. The remaining ends of all the three-way hoses 111 are installed together with a horizontal pipe 112 located above the rectangular frame 101. The water in the horizontal pipe 112 can enter each nozzle 110 through the three-way hose 111 and finally be sprayed out by it to achieve irrigation of vegetables.

[0049] like Figure 4 and Figure 6 As shown, two electric push rods 116 are symmetrically installed on the side of the shell 202, and the lower ends of the two electric push rods 116 are commonly installed with an adjusting rod 109, and both ends of the adjusting rod 109 are installed with limiting members 113. The upper ends of the two deflection racks 107 corresponding to the bottom of the slide 103 are commonly installed with T-shaped brackets 108 that pass through the slide 103 and slide on the adjusting rod 109. When the electric push rod 116 is extended, all the T-shaped brackets 108 are driven down through the adjusting rod 109, and when the electric push rod 116 is shortened, all the T-shaped brackets 108 are driven up.

[0050] In summary, when in use, each slide 103 is moved so that each vegetable column is between a corresponding set of vertical plates 104, and the electric push rod 116 is extended to drive the adjustment rod 109 to descend, so that each set of deflection racks 107 descends. When each set of two deflection racks 107 descends, the meshing deflection gear 106 rotates, driving the L-shaped plate 105 to rotate, and then the two L-shaped plates 105 deflect toward the center, so that the nozzle 110 faces the root of the corresponding vegetable column, and then the moving mechanism 2 drives the sprinkler mechanism 1 to move, and the water in the horizontal pipe 112 can enter through the three-way hose 111. The water is fed into each nozzle 110, and finally the nozzle 110 sprays water onto the soil at the roots of the vegetables to irrigate the vegetables. Since the roots of the vegetables can be effectively irrigated, the use of water can be reduced, thereby achieving the purpose of water saving. At the same time, the deflection angle of the nozzle 110 can be adjusted according to the descending height of the deflection rack 107, and then the direction of the nozzle 110 can be adjusted according to the thickness of the vegetable roots and stems to make it always face the root soil position, thereby preventing the nozzle 110 from spraying water onto the main trunk of the vegetable. At the same time, the water can also be replaced with liquid fertilizer, and the vegetables can be fertilized through the above operations.

[0051] like Figure 3 , Fig. 9 and Fig.10 As shown, a control mechanism 3 is provided in the shell 202, and the control mechanism 3 includes two side plates 301 symmetrically installed inside the shell 202, a cylinder 302 is installed between the two side plates 301, and a piston seat 303 is rotatably installed inside the cylinder 302, and the piston seat 303 is used to block water entering the cylinder 302.

[0052] like Fig.10 and Fig.11As shown, the side of the piston seat 303 is rectangular and has four through slots 304. The interior of the piston seat 303 has a cavity on one side of each through slot 304. A baffle 306 extending into the cavity is slidably arranged in the through slot 304. When the piston seat 303 rotates, the baffle 306 enters the cavity due to centrifugal force, thereby opening the through slot 304, and water can pass through the piston seat 303 through the through slot 304.

[0053] like Fig.11 As shown, the edge of the baffle 306 extending to the cavity is installed with a limit plate 305 adapted to the cavity, and a first spring 307 is arranged on one side of the limit plate 305 in the cavity. When the baffle 306 enters the cavity, the first spring 307 is compressed by the limit plate 305. When the piston seat 303 stops rotating to let the centrifugal force disappear, the first spring 307 rebounds and drives the baffle 306 to restore its position to re-block the through groove 304.

[0054] like Fig. 9 As shown, the control mechanism 3 also includes a small gear 310 rotatably mounted on the side of one of the side plates 301, a telescopic rod 308 extending into the cylinder 302 and connected to the side center of the piston seat 303 is mounted at the side center of the small gear 310, a large gear 311 meshing with the small gear 310 is mounted on the side of the side plate 301, the rotating large gear 311 drives the telescopic rod 308 to rotate through the small gear 310, and the rotating telescopic rod 308 drives the piston seat 303 to rotate.

[0055] like Figure 3 and Fig. 9 As shown, a synchronous wheel 312 is installed on the side center of the large gear 311 and one of the shafts 203 , and a synchronous belt 313 is provided on the two synchronous wheels 312 . The rotating shaft 203 drives the large gear 311 to rotate through the synchronous wheel 312 and the synchronous belt 313 .

[0056] like Fig.10 As shown, a partition 309 is provided on one side of the piston seat 303 in the cylinder 302 , and an output pipe 314 connected to the cross pipe 112 is installed on the side of the partition 309 , and water passing through the piston seat 303 enters the cross pipe 112 through the output pipe 314 .

[0057] like Fig. 9 and Fig.12As shown, a three-way pipe 316 is also provided in the shell 202, wherein two ends of the three-way pipe 316 are respectively connected to the cylinder 302 and the output pipe 314, and the last end extends to the outside of the shell 202. A solenoid valve 315 is installed on the three-way pipe 316 near the output pipe 314. When the solenoid valve 315 is closed, the through groove 304 is in a closed state, and no water enters the transverse pipe 112. When the solenoid valve 315 is opened, even if the through groove 304 is in a closed state, water can enter the transverse pipe 112 through the branch pipe of the three-way pipe 316 equipped with the solenoid valve 315, so that each nozzle 110 can continue to spray water.

[0058] In summary, when the solenoid valve 315 is closed, the rotating shaft 203 in the movable mechanism 2 drives the large gear 311 to rotate through the synchronous wheel 312 and the synchronous belt 313, and the rotating large gear 311 drives the telescopic rod 308 to rotate through the small gear 310, and the rotating telescopic rod 308 drives the piston seat 303 to rotate. The rotating piston seat 303 allows each baffle 306 to enter the cavity through the centrifugal force, so that the through groove 304 is opened, and water can pass through the piston seat 303 through the through groove 304, and then pass through the output pipe 314 enters the transverse tube 112, and when the baffle 306 enters the cavity, it compresses the first spring 307 through the limit plate 305. If the moving mechanism 2 stops moving due to its own structural damage or external obstruction, the central axis 203 of the moving mechanism 2 stops rotating, and then the piston seat 303 stops rotating. Without the centrifugal force, each first spring 307 rebounds and drives the baffle 306 back into the through groove 304 to block it, so that water cannot pass through the piston seat 303, and no water source enters the transverse tube 112.

[0059] If it is necessary to irrigate when the moving mechanism 2 is stopped, the solenoid valve 315 is opened. Even if the moving mechanism 2 is stopped, water can enter the horizontal pipe 112 through the branch pipe on which the solenoid valve 315 is installed on the three-way pipe 316, and irrigation can also be carried out.

[0060] Embodiment 2: Based on the first embodiment, Fig.13 and Fig.14 As shown, it also includes a fixing mechanism 4, which includes an iron plate 401 installed on the inner side of the rectangular frame 101 and on one side of the slide 103, an L-shaped seat 402 is installed on the upper edge of the slide 103, and a group of vertical rods 403 are arranged on the L-shaped seat 402. The lower ends of the two vertical rods 403 are jointly installed with magnets 404 that are magnetically attracted to the iron plate 401. When the magnets 404 are magnetically attracted to the iron plate 401, the slide 103 can be connected to the iron plate 401, and the slide 103 and the components installed thereon can be fixed.

[0061] like Fig.13 and Fig.14As shown, the upper ends of the two vertical rods 403 pass through the L-shaped seat 402 and are equipped with a pull ring 405. A second spring 406 is connected between the magnet 404 and the L-shaped seat 402. The pull ring 405 is pulled up to drive the magnet 404 and the iron plate 401 to disengage from the magnetic attraction through the vertical rod 403. At the same time, the upward moving magnet 404 will compress the second spring 406. When released, the second spring 406 rebounds and drives the magnet 404 and the iron plate 401 to be magnetically attracted again.

[0062] like Fig.10 and Fig.15 As shown, an air inlet pipe 320 is installed on the side of the cylinder 302 on one side of the partition 309, and a one-way valve 321 is installed on the air inlet pipe 320 near the cylinder 302. The one-way valve 321 can prevent the air and water inside the cylinder 302 from being discharged from the air inlet pipe 320, while allowing the outside air to enter the cylinder 302 through the air inlet pipe 320.

[0063] like Fig.10 and Fig.15 As shown, the side of the piston seat 303 is provided with a connecting groove 319 with an isosceles trapezoidal cross-section on the outside of the four through grooves 304, and a connecting ring 318 adapted thereto is rotatably installed in the connecting groove 319. A cylinder 317 with two telescopic arms extending into the cylinder 302 and fixedly connected to the connecting ring 318 is symmetrically installed on the side of one of the side plates 301. The cylinder 317 is extended to press the water between the piston seat 303 and the partition 309 into the horizontal pipe 112 through the output pipe 314.

[0064] In summary, after the sprinkler irrigation is completed, the cylinder 317 extends to press the water between the piston seat 303 and the partition 309 into the cross tube 112 through the output pipe 314, and then shortens to allow air to enter the piston seat 303 through the intake pipe 320. The cylinder 317 continues to shorten to press the air between the piston seat 303 and the partition 309 into the cross tube 112. After that, the cylinder 317 continues to expand and contract to allow air to continuously enter the cross tube 112. The continuously entering air sprays out the residual water in the cross tube 112 and the three-way hose 111 to avoid residual water in the pipeline. At the same time, during the fertilization process, the liquid fertilizer in the cross tube 112 and the three-way hose 111 can also be discharged to avoid fertilizer waste.

[0065] The present invention also discloses a water-saving vegetable fertilization and irrigation method, the method comprising the following steps: S1. Installation and adjustment. Install the device in the vegetable greenhouse and align each vegetable column with a slide 103. Specifically, install the device in the vegetable greenhouse and make the track 201 parallel to the vegetable column. Then pull up a pull ring 405 to drive the magnet 404 to release the magnetic attraction with the iron plate 401 through the vertical rod 403. Then move the slide 103 to align with the nearest vegetable column. Then release the pull ring 405 to rebound the second spring 406 to rebound and drive the magnet 404 to re-attract the iron plate 401. Re-fix the slide 103 and repeat the rising operation to align other slides 103 with the nearest vegetable column.

[0066] S2. Direction adjustment. Two nozzles 110 are installed on each slide 103 for deflection so as to face the soil at the roots of the corresponding vegetable columns. Specifically, the electric push rod 116 is extended to drive the adjustment rod 109 to descend, so that each set of deflection racks 107 descends. When each set of two deflection racks 107 descends, the meshing deflection gears 106 rotate, driving the L-shaped plates 105 to rotate, and then the two L-shaped plates 105 deflect toward the center, so that the nozzles 110 face the roots of the corresponding vegetable columns.

[0067] S3. The device moves, and the moving mechanism 2 drives the sprinkler mechanism 1 to move toward the vertical direction of the vegetable column. Specifically, when the motor 207 is running, it drives the first gear 205 to rotate. The rotating first gear 205 drives the shaft 203 to rotate through the second gear 206. The rotating shaft 203 drives the track wheels 204 at both ends to rotate, so that it moves on the track 201, thereby driving the shell 202 to move, and the moving shell 202 drives the sprinkler mechanism 1 to move.

[0068] S4, vegetable sprinkler irrigation. During the operation of the mobile mechanism 2, the sprinkler mechanism 1 and the control mechanism 3 are cooperated to irrigate the soil at the roots of the vegetables. Specifically, one end of the three-way pipe 316 is connected to the water supply end. The rotating shaft 203 in the moving mobile mechanism 2 drives the large gear 311 to rotate through the synchronous wheel 312 and the synchronous belt 313. The rotating large gear 311 drives the telescopic rod 308 to rotate through the small gear 310. The rotating telescopic rod 308 drives the piston seat 303 to rotate. The rotating piston seat 303 allows each baffle 306 to enter the cavity through centrifugal force. At the same time, the first spring 307 will be compressed by the limit plate 305 to open the through groove 304. Water can pass through the piston seat 303 through the through groove 304, and then enter the horizontal pipe 112 through the output pipe 314, and then pass through each three-way hose 111 and sprayed to the soil at the roots of the vegetables by the nozzle 110 to achieve irrigation. Until the device moves from one end of the vegetable column to the other end, the irrigation is completed.

[0069] S5. Stop protection. When the track 201 stops moving, each nozzle 110 can be controlled to stop spraying water. Specifically, if the moving mechanism 2 stops moving due to structural damage or external obstruction, the central axis 203 of the moving mechanism 2 stops rotating, and then the piston seat 303 stops rotating. Without the centrifugal force, each first spring 307 rebounds and drives the baffle 306 back into the through groove 304 to block it. Then water cannot pass through the piston seat 303, so that no water source enters the cross pipe 112, and each nozzle 110 stops spraying water, thereby reducing water waste.

[0070] S6, mode change, by opening the solenoid valve 315, the device is converted to a mode in which the nozzle 110 sprays water even when the movement stops. Specifically, the solenoid valve 315 is opened, and even if the moving mechanism 2 is in a stopped state and the through groove 304 is closed, water can enter the horizontal pipe 112 through the branch pipe on the three-way pipe 316 equipped with the solenoid valve 315, and irrigation can also be carried out. There are multiple irrigation modes for users to choose from. At the same time, the port of the three-way pipe 316 can also be connected to the liquid fertilizer supply end, and then the vegetables can be fertilized through S1-S5.
