Description

Technical Field

[0001] This utility model relates to the field of dryland irrigation technology, specifically to an irrigation device for agricultural dryland. Background Technology

[0002] Dryland farming refers to arable land without irrigation facilities that relies mainly on natural rainfall to grow drought-tolerant crops. Irrigating dryland is primarily to supplement the water needed for crop growth, ensure normal physiological activities of crops, and increase yield. Current irrigation methods mainly include flood irrigation, drip irrigation, and sprinkler irrigation. For example, sprinkler irrigation mainly uses nozzles to spray water into the air, forming water droplets that then fall onto the field. However, the water can only be sprayed onto the surface of the soil, resulting in relatively high water evaporation. A large amount of water resources are lost before being fully absorbed by crops, causing waste. At the same time, it can easily lead to soil compaction. Long-term surface irrigation will damage the soil structure, reduce soil aeration and permeability, which is not conducive to crop root respiration and growth, thus reducing the irrigation effect on dryland.

[0003] In view of this, we propose an irrigation device for dry farmland. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides an irrigation device for dryland agriculture, which effectively solves the problems of existing sprinkler irrigation, where water can only be sprayed onto the soil surface, resulting in large water evaporation and waste. At the same time, it can easily cause soil compaction, reduce soil aeration and permeability, which is not conducive to crop root respiration and growth, and reduces irrigation effectiveness.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides an irrigation device for dry farmland, including a mobile carrier and a support shell connected by a universal arm, and a soil turning frame is provided inside the support shell;

[0007] A fixed frame is fixedly connected to the side of the support shell away from the mobile vehicle via a telescopic rod. Multiple sets of conical cylinders are fixedly connected to the side of the fixed frame away from the support shell, and nozzles are fixedly connected to the inner walls of the multiple sets of conical cylinders.

[0008] The fixed frame is equipped with a drive assembly that connects to the soil turning frame, and the support housing is equipped with a water supply assembly that connects to multiple sets of nozzles.

[0009] Furthermore, the drive assembly includes connecting rods rotatably connected to both sides of the fixed frame, cranks rotatably connected to the ends of the two sets of connecting rods away from the fixed frame, and fixed shafts fixedly connected to the ends of the two sets of cranks away from the connecting rods.

[0010] Furthermore, a sprocket is fixedly connected to the surface of the fixed shaft, and a sprocket is connected to the surface of the sprocket through a synchronous chain. One side of the sprocket is rotatably connected to the inner cavity sidewall of the support housing, and the other side of the sprocket is fixedly connected to one end of the soil turning frame.

[0011] Furthermore, the end of the soil-turning frame furthest from sprocket two rotates through the supporting housing;

[0012] A motor is fixedly connected to one side of the support shell, and the motor is fixedly connected to the end of the soil turning frame that passes through the support shell via an output shaft.

[0013] Furthermore, the water supply assembly includes multiple sets of corrugated pipes fixedly connected to the top of the nozzles, with a water supply pipe fixedly connected to the end of the corrugated pipe away from the nozzle, and the bottom of the water supply pipe fixedly connected to the top of the support housing.

[0014] Furthermore, a water pump is fixedly connected to one side of the water supply pipe, and a water storage tank is fixedly connected to the side of the water pump away from the water supply pipe. The bottoms of both the water pump and the water storage tank are fixedly connected to the top of the support shell.

[0015] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0016] This invention uses a conical cylinder to deliver water into the soil, significantly reducing water loss through evaporation at the soil surface. The water, penetrating deep into the soil, can be directly absorbed and utilized by crop roots, improving water resource utilization efficiency and reducing water waste caused by excessive evaporation. The soil-turning frame agitates the soil during operation, effectively improving soil structure. This agitation breaks up soil compaction, increases porosity between soil particles, allowing air to enter the soil more smoothly, providing sufficient oxygen to crop roots and promoting root respiration. Simultaneously, the good permeability facilitates the even distribution and infiltration of water in the soil, preventing localized waterlogging and creating a more suitable soil environment for crop growth, further improving irrigation effectiveness.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] An irrigation device for dry farmland includes a mobile carrier 1 and a support housing 3 connected by a universal arm 2. A soil turning frame 5 is provided inside the support housing 3. A fixed frame 9 is fixedly connected to the side of the support housing 3 away from the mobile carrier 1 via a telescopic rod 13. Multiple sets of conical cylinders 10 are fixedly connected to the side of the fixed frame 9 away from the support housing 3. Sprinklers 19 are fixedly connected to the inner walls of the multiple sets of conical cylinders 10. A drive assembly connected to the soil turning frame 5 is provided on the surface of the fixed frame 9. A water supply assembly connected to the multiple sets of sprinklers 19 is provided on the support housing 3.

[0025] Specifically, the mobile carrier 1 can move the relevant components on the support shell 3, and watering can be carried out simultaneously when moving in the farmland. The universal arm 2 can adjust the angle, height and position of the support shell 3 and the components on the support shell 3. The drive component can drive the soil turning frame 5 to rotate and turn the farmland soil. While turning the soil, the drive component can drive the fixed frame 9 to move up and down. When moving down, the conical cylinder 10 can be inserted into the soil. At the same time, in conjunction with the water supply component, water can be sprayed using the conical cylinder 10. At this time, the water can not only be sprayed and irrigated to the soil surface, but also penetrate into the soil. After the soil turning frame 5 loosens the soil, the water can more easily seep into the soil.

[0026] Specifically, the drive assembly includes connecting rods 8 rotatably connected to both sides of the fixed frame 9. Cranks 7 are rotatably connected to the ends of the two sets of connecting rods 8 away from the fixed frame 9. Fixed shafts 6 are fixedly connected to the ends of the two sets of cranks 7 away from the connecting rods 8. A sprocket 16 is fixedly connected to the surface of the fixed shaft 6. A sprocket 27 is meshed with the surface of the sprocket 16 through a synchronous chain 18. One side of the sprocket 217 is rotatably connected to the inner cavity side wall of the support housing 3. The other side of the sprocket 217 is fixedly connected to one end of the soil turning frame 5. The end of the soil turning frame 5 away from the sprocket 217 rotates through the support housing 3. A motor 4 is fixedly connected to one side of the support housing 3. The motor 4 is fixedly connected to the end of the soil turning frame 5 that passes through the support housing 3 through an output shaft.

[0027] Specifically, starting the motor 4 can drive the soil turning frame 5 to rotate. The synchronous chain 18 on the surface of the second sprocket 17 can drive the first sprocket 16 to rotate. In turn, the fixed shaft 6 connected to the first sprocket 16 can drive the two sets of cranks 7 to rotate. Because the fixed frame 9 is limited and guided by the two sets of telescopic rods 13, when the cranks 7 rotate, the fixed frame 9 can be driven to move up and down reciprocally through the connecting rod 8.

[0028] Furthermore, the water supply assembly includes a corrugated pipe 12 fixedly connected to the top of multiple sets of nozzles 19. A water supply pipe 14 is fixedly connected to the end of the corrugated pipe 12 away from the nozzles 19. The bottom of the water supply pipe 14 is fixedly connected to the top of the support housing 3. A water pump 15 is fixedly connected to one side of the water supply pipe 14. A water storage tank 11 is fixedly connected to the side of the water pump 15 away from the water supply pipe 14. The bottoms of the water pump 15 and the water storage tank 11 are both fixedly connected to the top of the support housing 3.

[0029] Specifically, starting the water pump 15 can draw water from the storage tank 11 into the water supply pipe 14. The corrugated pipe 12 connected to the water supply pipe 14 can stably supply water to multiple nozzles 19. The corrugated pipe 12 has good extensibility and can stably supply water to the nozzles 19 when the fixed frame 9 drives the nozzles 19 to move.

[0030] The working principle of this utility model is as follows: The mobile carrier 1 provides mobility for the entire device, allowing it to move quickly through farmland and reach areas requiring irrigation, thus improving work efficiency. The universal arm 2 is connected to the mobile carrier 1 at one end and to the support housing 3 at the other. It consists of multiple movable joints, possessing multiple degrees of freedom. By operating the joints of the universal arm 2, it can rotate horizontally and adjust its angle vertically. Furthermore, it can flexibly adjust the position and height of the support housing 3 and its components according to the actual terrain and factors such as crop planting spacing and height, allowing the entire device to better adapt to different farmland environments and irrigation needs. When the motor 4 is started, its output shaft begins to rotate, and this rotational power is directly transmitted to the fixed... The fixed-connection soil-turning frame 5 rotates around its own axis. This rotation agitates the soil in the farmland, breaking up soil compaction and loosening it to create favorable conditions for subsequent water penetration. Simultaneously, the associated transmission mechanism also activates. One end of the soil-turning frame 5 is fixedly connected to a second sprocket 17. When the soil-turning frame 5 rotates, the second sprocket 17 rotates synchronously. The second sprocket 17 and the first sprocket 16 are meshed together via a synchronous chain 18. The rotation of the second sprocket 17 drives the synchronous chain 18, which in turn drives the first sprocket 16 to rotate. The first sprocket 16 is fixedly mounted on a fixed shaft 6, so the rotation of the first sprocket 16 causes the fixed shaft 6 to rotate as well. Both ends of the fixed shaft 6 are connected to cranks 7. As the fixed shaft 6 rotates, the cranks 7 rotate around the fixed shaft 6. The other end of the cranks 7 is rotatably connected to the fixed frame 9 via a connecting rod 8. The fixed frame 9 is limited and guided by the telescopic rod 13. Due to the limitation of the telescopic rod 13, the fixed frame 9 cannot move arbitrarily and can only move up and down within the range allowed by the telescopic rod 13. When the cranks 7 rotate, the connecting rod 8 converts the rotation into the reciprocating motion of the fixed frame 9. During the downward movement of the fixed frame 9, multiple sets of conical cylinders 10 connected to the side of the fixed frame 9 away from the supporting housing 3 are gradually inserted into the soil, preparing for subsequent watering into the soil. After the water pump 15 is started, the water pump 15 begins to work, utilizing its own... The pump 10 has the ability to draw water from the storage tank 11 and press it into the water supply pipe 14. The water supply pipe 14 is the main channel of the entire water supply system. It delivers the water drawn by the water pump 15 to each nozzle 19. Between the water supply pipe 14 and the nozzle 19, there is a corrugated pipe 12. The corrugated pipe 12 has good flexibility and extensibility. It can extend and retract accordingly as the position of the nozzle 19 changes during the up and down movement of the fixed frame 9. In this way, no matter what position the nozzle 19 is in, the corrugated pipe 12 can ensure a stable water supply to the nozzle 19. When the cone 10 is inserted into the soil, the nozzle 19 starts to spray water. Part of the water sprayed by the nozzle 19 is directly sprayed onto the soil surface to moisten the surface soil.Another portion of the water penetrates deep into the soil through the conical tube 10, directly supplying water to the crop roots. Furthermore, because the soil has been turned over by the soil-turning frame 5, it has become looser and more porous, making it easier for water to penetrate and diffuse within the soil, thus achieving more comprehensive and efficient irrigation of dryland fields.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
