Description

Technical Field

[0001] This utility model relates to the field of crop irrigation devices, specifically to an adaptive mobile water and fertilizer irrigation device. Background Technology

[0002] Modern agricultural facility planting requires precise watering and irrigation of crops in seedbeds or fields. If integrated water and fertilizer management is adopted, fertilizer application is also involved. Water and fertilizer management will account for a large proportion of the cost throughout the planting period. Under the current conditions of general agricultural labor shortage, the lack of refined planting management due to human factors can easily lead to uneven plant growth, affecting the uniformity of planted crops and thus affecting the quality of agricultural products, especially the more stringent water and fertilizer management during the flowering period.

[0003] Existing crop irrigation systems have the following shortcomings:

[0004] 1. The device lacks a switching function, making it unable to be installed for both mobile irrigation in existing seedbeds and mobile irrigation in fields, resulting in poor flexibility.

[0005] 2. Different types of crops have different nutrient requirements, and it is impossible to provide water and fertilizer for different types of crops accordingly, so the practicality of the device needs to be improved. Utility Model Content

The other two first travel wheels and the other two second travel wheels are rotatably mounted on the bottom and top of the other support frame respectively via a second rotating shaft.

[0012] The sprinkler mechanism is located on the top of the support plate. The sprinkler mechanism includes a first diverter pipe, a second diverter pipe, two angle adjustment components, and several nozzles. The top of the support plate has an installation groove. The first diverter pipe and the second diverter pipe are both fixedly installed above the installation groove. The two angle adjustment components are symmetrically arranged inside the installation groove. Several nozzles are evenly spaced on the two angle adjustment components.

[0013] Preferably, each drive assembly includes a dual-axis motor and two transmission rods. The dual-axis motor is fixedly mounted on one of the support frames, and the two transmission rods are respectively fixedly mounted on the two output ends of the dual-axis motor.

[0014] Preferably, each transmission component includes a timing belt and two timing pulleys. The two timing pulleys are respectively fixed on the outer wall of one of the transmission rods and one of the first rotating shafts, and the timing belt is sleeved between the two timing pulleys.

[0016] Preferably, one end of each support frame is fixedly connected to the output end of one of the stepper motors via a connecting rod, and the other end of each support frame is rotatably connected to the support plate via a third rotating shaft.

[0017] Preferably, each angle adjustment component includes a forward and reverse motor, a first gear, a second gear, a mounting rod, and several rigid tubes.

[0020] The beneficial effects of this utility model are:

[0021] 1. This utility model, through the design of a travel mechanism and a switching mechanism, incorporates four first traveling wheels and four second traveling wheels. The outer walls of the four first traveling wheels are designed with slots that can engage with the retaining edges at both ends of the top of the seedbed, enabling the device to travel and irrigate on the seedbed. Simultaneously, all four first traveling wheels are made of nylon or lightweight metal, which helps reduce wear on the seedbed. Two stepper motors enable the two support frames to rotate 180 degrees. The four second traveling wheels can travel between ridges in the field, enabling the device to travel and irrigate on the ground. This gives the device a switching function, allowing for rapid switching according to actual needs to meet the water and fertilizer irrigation requirements of different environments, achieving an adaptive effect and thus improving the flexibility of the device.

[0022] 2. This utility model designs a sprinkler irrigation mechanism, namely a first diversion pipe, a second diversion pipe, two angle adjustment components, and several nozzles. Different types of crops have different nutrient requirements, resulting in different types of water and fertilizer needed. For example, leafy vegetables should be given high-nitrogen water-soluble fertilizer, while fruiting vegetables should be given high-potassium water-soluble fertilizer. Therefore, the first and second diversion pipes are designed to deliver different types of water and fertilizer according to the crop type. This prevents the water and fertilizer components from being mixed when a single diversion pipe delivers different types of water and fertilizer, which would affect the irrigation effect. This satisfies the water and fertilizer irrigation requirements of different types of crops, which is beneficial to improving the growth rate of crops and also enhances the practicality of this device.

[0023] 3. This utility model, by designing two angle adjustment components, can drive several nozzles to swing left and right during the automatic movement of the device, thereby increasing the spraying range of water and fertilizer, improving spraying efficiency, and avoiding spraying dead zones, thus improving the spraying effect of water and fertilizer.

Detailed Implementation

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0033] Reference Figures 1 to 5 As shown, the adaptive mobile water and fertilizer irrigation device includes a support plate 1; it also includes a switching mechanism, a traveling mechanism and a sprinkler mechanism;

[0034] The switching mechanism is located on the outer wall of the support plate 1. The switching mechanism includes two stepper motors 2 and two lifting components. The two stepper motors 2 are inserted into the outer wall of one end of the support plate 1, and the two lifting components are symmetrically arranged on the outer walls of both ends of the U-shaped plate.

[0035] The travel mechanism is located on the outer wall of the support plate 1. The travel mechanism includes two support frames 3, two drive components, four first travel wheels 4, four second travel wheels 5, and four transmission components. Each support frame 3 is rotatably mounted on one end of the support plate 1. The two drive components are symmetrically arranged on one of the support frames 3, and the four transmission components are symmetrically arranged on one of the support frames 3. The two first travel wheels 4 and two of the second travel wheels 5 are rotatably mounted on the bottom and top of one of the support frames 3 respectively via a first rotating shaft 6. The other two first travel wheels 4 and the other two second travel wheels 5 are rotatably mounted on the bottom and top of another support frame 3 respectively via a second rotating shaft 7. The four first travel wheels 4 are all made of nylon wheels or lightweight metal wheels, which helps to reduce wear on the seedbed.

[0036] The sprinkler system is located on the top of the support plate 1. The sprinkler system includes a first diversion pipe 8, a second diversion pipe 9, two angle adjustment components, and several nozzles 10. The top of the support plate 1 has an installation groove. The first diversion pipe 8 and the second diversion pipe 9 are both fixedly installed above the installation groove. The two angle adjustment components are symmetrically arranged inside the installation groove. Several nozzles 10 are evenly spaced on the two angle adjustment components. It should be noted that different types of crops have different nutrient requirements, which leads to different types of water and fertilizer required. For example, leafy vegetables should be given high-nitrogen water-soluble fertilizer, while fruiting vegetables should be given high-potassium water-soluble fertilizer. Therefore, the first diversion pipe 8 and the second diversion pipe 9 are designed to deliver different types of water and fertilizer according to the crop type. This prevents the water and fertilizer composition from being mixed when a single diversion pipe delivers different types of water and fertilizer, which would affect the irrigation effect. This meets the water and fertilizer irrigation requirements of different types of crops and helps to improve the growth rate of crops.

[0037] Reference Figures 1 to 5 As shown, each drive component includes a dual-axis motor 11 and two transmission rods 12. The dual-axis motor 11 is fixedly mounted on one of the support frames 3, and the two transmission rods 12 are respectively fixed on the two output ends of the dual-axis motor 11. This device is equipped with a controller, and all electrical devices on the device are electrically connected to the controller. When the device is placed on top of the seedbed, the four first traveling wheels 4 of the device are engaged with the retaining edges at both ends of the top of the seedbed. The dual-axis motor 11 is started by the controller, so that its two output ends drive the two transmission rods 12 to rotate simultaneously.

[0038] Reference Figures 1 to 5As shown, each transmission component includes a synchronous belt 13 and two synchronous pulleys 14. The two synchronous pulleys 14 are respectively fixed on the outer wall of one of the transmission rods 12 and one of the first rotating shafts 6. The synchronous belt 13 is sleeved between the two synchronous pulleys 14. When the two transmission rods 12 rotate simultaneously, since the two synchronous pulleys 14 are respectively fixedly connected to one of the transmission rods 12 and one of the first rotating shafts 6, the two synchronous pulleys 14 are connected by the synchronous belt 13, thereby driving the two first traveling wheels 4 to rotate. In conjunction with the two first traveling wheels 4 on another support frame 3, the device can automatically travel on the top of the seedbed to facilitate water and fertilizer irrigation for the crops planted on the seedbed.

[0039] Reference Figures 1 to 5 As shown, each lifting component includes a hydraulic rod 15, a push plate 16, and several insert rods 17. Two L-shaped plates are symmetrically arranged on the outer wall of the support plate 1. The hydraulic rod 15 is inserted into the bottom of one of the L-shaped plates. The push plate 16 is fixed on its output end. Several insert rods 17 are fixed on the bottom of the push plate 16. Two guide rods are symmetrically arranged on the top of the push plate 16. Each guide rod is inserted into the L-shaped plate. When it is necessary to irrigate the crops planted on the ground ridge, the device is first removed from the top of the seedbed and placed on the ground. Then, the hydraulic rod 15 is activated by the controller, so that its output end extends downward. Since its output end is fixedly connected to the push plate 16, under the guidance of the two guide rods, the push plate 16 and several insert rods 17 at its bottom are driven to descend vertically until the push plate 16 is in contact with the ground. The several insert rods 17 on the push plate 16 are inserted into the soil. At this time, the device is in a suspended state, that is, the four first traveling wheels 4 are out of contact with the ground.

[0040] Reference Figures 1 to 5As shown, one end of each support frame 3 is fixedly connected to the output end of one of the stepper motors 2 via a connecting rod 18, and the other end of each support frame 3 is rotatably connected to the support plate 1 via a third rotating shaft 19. When the four first traveling wheels 4 are no longer in contact with the ground, the controller first starts one of the stepper motors 2. Since one end of each support frame 3 is fixedly connected to the output end of one of the stepper motors 2 via a connecting rod 18, and the other end of each support frame 3 is rotatably connected to the support plate 1 via a third rotating shaft 19, one of the support frames 3 is rotated 180 degrees, causing two of the second traveling wheels 5 to rotate to a position close to the ground but suspended in the air. Then, the controller starts another stepper motor 2, which drives another support frame 3 to rotate 180 degrees, so that the other two second walking wheels 5 rotate to be close to the ground but in a suspended state. Then, the controller drives the output ends of the two hydraulic rods 15 to retract, thereby driving the push plate 16 and several insert rods 17 to retract to the initial position, that is, the push plate 16 and several insert rods 17 are separated from the ground, so that the four suspended second walking wheels 5 descend to contact the ground. Then, the controller starts another drive component, which can realize the movement of the four second walking wheels 5, thereby realizing the automatic movement of this device, so as to facilitate the irrigation of crops planted on the ground ridges.

[0041] Reference Figures 1 to 5 As shown, each angle adjustment component includes a reversible motor 20, a first gear 21, a second gear 22, a mounting rod 23, and several rigid tubes 24. The reversible motor 20 is fixedly mounted on the top of the support plate 1. The first gear 21 is fixedly mounted on its output end. The mounting rod 23 is rotatably mounted inside the mounting groove via two rotating rods 25. The second gear 22 is fixedly mounted on one of the rotating rods 25. The first gear 21 and the second gear 22 are meshed together. Several rigid tubes 24 are fixedly mounted on the outer wall of the mounting rod 23. Each nozzle 10 is fixedly mounted at the bottom end of a rigid tube 24. When adjustment is required... When the spraying range is adjusted, the controller starts the forward and reverse motor 20, which drives the first gear 21 to rotate through its output end. Since the second gear 22 is fixedly connected to one of the rotating rods 25, the mounting rod 23 is rotatably connected to the mounting groove through the two rotating rods 25. The first gear 21 and the second gear 22 are meshed together. Several rigid tubes 24 are fixedly connected to the mounting rod 23, and each nozzle 10 is fixedly connected to the bottom end of a rigid tube 24. This causes several nozzles 10 to swing left and right, increasing the spraying range of water and fertilizer, improving spraying efficiency, and avoiding spraying omissions, thus improving the spraying effect.

[0042] Reference Figures 1 to 5As shown, several flexible hoses 26 are fixedly installed on the outer walls of the first diversion pipe 8 and the second diversion pipe 9. The bottom end of each flexible hose 26 is fixedly connected to the top end of a rigid pipe 24. A connecting pipe 27 is fixedly installed at one end of the first diversion pipe 8 and the second diversion pipe 9. The design of the flexible hoses 26 is to ensure that the mounting rod 23 can flexibly drive the rigid pipe 24 and the nozzle 10 to rotate. The connecting pipe 27 facilitates the quick connection between the first diversion pipe 8 or the second diversion pipe 9 and the flexible hose 26 for conveying water and fertilizer on the winch mechanism. The winch mechanism is used to wind or unwind the flexible hose 26 for conveying water and fertilizer to realize the adaptive mobile water and fertilizer irrigation of this device. It should be noted that the winch mechanism is existing technology. The winch mechanism includes a motor, and a winding disc is fixedly installed on the output end of the motor to facilitate the winding or unwinding of the flexible hose 26 for conveying water and fertilizer. The other end of the flexible hose 26 for conveying water and fertilizer is connected to a water and fertilizer tank through a water pump to realize the supply of water and fertilizer to the planted crops.

[0043] Reference Figures 1 to 5 As shown, each of the first traveling wheels 4 has an integrally formed groove 28 on its outer wall in the circumferential direction. The groove 28 allows the four first traveling wheels 4 on this device to be engaged on the side rails of the seedbed, thus satisfying the matching use of this device with the seedbed and enabling this device to move automatically on the top of the seedbed to realize water and fertilizer irrigation.
