Description

Technical Field

[0001] This utility model relates to the technical field of water-saving irrigation equipment, specifically water-saving irrigation equipment for alfalfa planting. Background Technology

[0002] Alfalfa, a perennial herbaceous plant, is known as the "King of Forage" due to its high nutritional value. Rich in protein, vitamins, and minerals, it is an indispensable high-quality feed for livestock, especially dairy cattle. Alfalfa can be mowed multiple times during the growing season, typically using lawnmowers. However, during mowing, the tractor, which powers the mower, can easily crush drip irrigation tape laid on the ground into the soil, causing blockages or structural damage to the tape's outlets and severely impacting the normal operation and lifespan of the irrigation system. Therefore, developing and selecting a water-saving irrigation method adapted to the characteristics of alfalfa cultivation to overcome these problems has become a critical technical issue that urgently needs to be addressed. Utility Model Content

[0003] In response to the existing problems, this utility model provides a water-saving irrigation device for alfalfa planting to solve the problems mentioned in the background art.

[0004] To address the existing problems, this utility model provides a water-saving irrigation device for alfalfa cultivation, comprising symmetrically distributed support plates. A front wheel frame and a rear wheel frame are fixedly connected to the lower ends of the support plates, respectively. A drive wheel is rotatably connected to the front wheel frame, and a driven wheel is rotatably connected to the rear wheel frame. A gearbox is mounted on the side wall of the front wheel frame, and the output shaft of the gearbox is fixedly connected to the axle of the drive wheel. The input shaft of the gearbox is fixedly connected to the output shaft of a drive motor fixedly mounted thereon. A telescopic assembly is fixedly connected to the upper part of the support plate, and a spraying assembly is fixedly connected to the upper end of the telescopic assembly. A battery and a support frame are fixedly connected to the support plate and to both sides of the telescopic assembly. A winding disc is rotatably connected to the upper part of the support frame. The axle of the winding disc passes through the side wall of the support frame and is fixedly connected to a driven sprocket. A drive sprocket is fixedly connected to one end of the axle of the driven wheel located below the winding disc, and the drive sprocket is connected to the driven sprocket via a chain.

[0005] Furthermore, the telescopic assembly includes a fixed tube, a movable tube, a connector, a lower flange, a lower connector, an upper connector, and an electric cylinder. The lower end of the fixed tube is fixedly connected to the upper part of the support plate, and the upper end of the fixed tube is slidably connected to the movable tube. The upper end of the movable tube is fixedly connected to the connector, and the upper end of the connector is fixedly connected to the lower flange. The lower connector is fixedly connected to the wall of the fixed tube, and the upper connector is fixedly connected to the wall of the movable tube near its upper end. The two ends of the electric cylinder are fixedly connected to the lower connector and the upper connector, respectively.

[0006] Furthermore, the spraying assembly includes an upper flange, bolts, a mounting bracket, spray bars, and nozzles. The upper flange is located above the lower flange and is connected to the lower flange by bolts. A mounting bracket is fixedly connected to the upper flange, and two spray bars are fixedly connected below the mounting bracket. Nozzles are provided on the lower wall of the spray bars.

[0007] Furthermore, the two spray bars are symmetrically distributed relative to the mounting bracket, with the ends of the two spray bars that are close to each other being blocked, and the ends that are far apart being connected to a water supply pipe on the coil.

[0008] Furthermore, the battery component includes a protective shell, a screw, and a sealing cap. The sealing cap is fixedly installed on the side end of the protective shell by the screw, and a storage battery is installed inside the sealing cap.

[0009] Furthermore, the battery unit integrates a controller, which is electrically connected to the electric cylinder and the drive motor. The controller also has a built-in wireless signal module for remote user control.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, by setting up a support plate, front wheel frame, rear wheel frame, drive wheel, driven wheel, drive motor and gearbox, allows the drive motor to drive the gearbox to rotate during operation, so that the drive wheels and driven wheels on both sides of the equipment can travel along the side of the field and complete water spraying irrigation. Unlike the traditional irrigation method of laying drip irrigation tape on the ground, this invention fundamentally solves the problem of water outlet blockage and structural damage caused by the traction machinery and grass cutting machinery crushing the drip irrigation tape during alfalfa cutting operations.

[0012] 2. This utility model establishes a transmission connection by setting a driven wheel, a pipe winding disc, a drive sprocket, a chain, and a driven sprocket. When the equipment moves forward to spray water for irrigation, the rotation of the driven wheel will synchronously drive the drive sprocket, which in turn drives the driven sprocket to rotate through the chain, thereby causing the pipe winding disc to release the water supply pipe in an orderly manner. When the equipment moves backward, the pipe winding disc will rotate in the opposite direction to realize the automatic winding of the water supply pipe. This design ensures that the water supply pipe is wound and unwound in an orderly manner during the movement of the equipment, completely avoiding problems such as pipe accumulation, tangling, and knotting.

[0013] 3. By setting up a telescopic component, this utility model can adjust the extension and retraction of the electric cylinder according to the height requirements of alfalfa at different growth stages and the plant status before and after cutting. The electric cylinder can drive the movable tube to slide inside the fixed tube, thereby driving the spraying component to rise and fall synchronously, so that the nozzle is in the optimal irrigation position that is suitable for the growth height of alfalfa.

[0020] Please see Figure 1-4 A water-saving irrigation device for alfalfa cultivation includes symmetrically distributed support plates 1. A front wheel frame 2 and a rear wheel frame 3 are fixedly connected to the lower ends of the support plates 1, respectively. A drive wheel 4 is rotatably connected to the front wheel frame 2, and a driven wheel 5 is rotatably connected to the rear wheel frame 3. A gearbox 6 is mounted on the side wall of the front wheel frame 2. The output shaft of the gearbox 6 is fixedly connected to the axle of the drive wheel 4, and the input shaft of the gearbox 6 is fixedly connected to the output shaft of a drive motor 7 fixedly mounted thereon. A telescopic [device / mechanical device] is fixedly connected to the upper part of the support plates 1. Component 8, the upper end of the telescopic component 8 is fixedly connected to the spraying component 9, the bearing plate 1 is fixedly connected to the battery component 10 and the support frame 11 on both sides of the telescopic component 8, the upper part of the support frame 11 is rotatably connected to the winding pipe disc 12, the disc shaft of the winding pipe disc 12 passes through the side wall of the support frame 11 and is fixedly connected to the driven sprocket 13, one end of the axle of the driven wheel 5 located below the winding pipe disc 12 is fixedly connected to the drive sprocket 14, the drive sprocket 14 is connected to the driven sprocket 13 through the chain 15.

[0021] It should be noted that the synchronous rotation control of the two drive motors 7 and the synchronous lifting control of the two electric cylinders 807 can both be achieved using synchronous control techniques known in the art, such as a PID controller with feedback closed loop, which is existing technology and will not be elaborated here.

[0022] The telescopic assembly 8 includes a fixed pipe 801, a movable pipe 802, a connector 803, a lower flange 804, a lower connector 805, an upper connector 806, and an electric cylinder 807. The lower end of the fixed pipe 801 is fixedly connected to the upper part of the bearing plate 1. The upper end of the fixed pipe 801 is slidably connected to the movable pipe 802. The upper end of the movable pipe 802 is fixedly connected to the connector 803. The upper end of the connector 803 is fixedly connected to the lower flange 804. The lower connector 805 is fixedly connected to the pipe wall of the fixed pipe 801. The upper connector 806 is fixedly connected to the pipe wall of the movable pipe 802 near the upper end. The two ends of the electric cylinder 807 are fixedly connected to the lower connector 805 and the upper connector 806, respectively.

[0023] The spraying assembly 9 includes an upper flange 901, bolts 902, a mounting bracket 903, spray bars 904, and nozzles 905. The upper flange 901 is located above the lower flange 804 and is connected to the lower flange 804 by bolts 902. The mounting bracket 903 is fixedly connected to the upper flange 901. Two spray bars 904 are fixedly connected to the lower part of the mounting bracket 903. Nozzles 905 are provided on the lower wall of the spray bars 904.

[0024] Among them, the two spray bars 904 are symmetrically distributed relative to the mounting bracket 903. The ends of the two spray bars 904 that are close to each other are blocked, and the ends that are far apart are connected to the water supply pipe on the coil 12.

[0025] The battery component 10 includes a protective shell 1001, a screw 1002, and a sealing cover 1003. The sealing cover 1003 is fixedly installed on the side of the protective shell 1001 by the screw 1002, and a storage battery is installed inside the sealing cover 1003.

[0026] The battery unit 10 integrates a controller, which is electrically connected to the electric cylinder 807 and the drive motor 7. The controller has a built-in wireless signal module for remote control by the user.

[0027] Working principle: First, the battery inside the battery unit 10 provides power to the entire device. After receiving remote or preset commands from the user, the integrated controller sends an operating command to the drive motor 7. The drive motor 7 starts, and its output shaft transmits power to the connected gearbox 6. The gearbox 6 adjusts the power speed and then transmits power to the drive wheel 4 through its output shaft. The drive wheel 4 starts to rotate, and the driven wheel 5 follows the rotation, causing the device to move. When the device moves, both the drive wheel and the driven wheel on both sides are located on either side of the alfalfa field.

[0028] When the equipment moves forward to perform water spraying irrigation, the driven wheel 5, which is rotatably connected to the rear wheel frame 3, rotates with the movement of the equipment. The drive sprocket 14, which is fixedly connected to one end of the axle of the driven wheel 5, also rotates synchronously. Since the drive sprocket 14 is connected to the driven sprocket 13 fixed on the shaft of the pipe-wound disc 12 via the chain 15, the rotational power of the drive sprocket 14 is transmitted to the driven sprocket 13 through the chain 15, thereby driving the pipe-wound disc 12, which is fixed to the driven sprocket 13, to rotate around the rotational connection point on the upper part of the support frame 11. During the rotation of the pipe-wound disc 12, the water supply pipe wound on it is gradually released. One end of the water supply pipe is connected to the spray bar 904. During the release process, it continuously supplies water to the spraying assembly 9. Due to the orderly rotation of the pipe-wound disc 12, the water supply pipe is released neatly and orderly, avoiding accumulation. When the equipment has completed the irrigation of the current area... When the device needs to retract to its initial position, the drive motor 7 reverses, causing the drive wheel 4 to rotate in the opposite direction, thus retracting the entire device. At the same time, the driven wheel 5 also rotates in the opposite direction, which in turn causes the drive sprocket 14 to rotate in the opposite direction. This reverse rotational power is transmitted to the driven sprocket 13 via the chain 15, causing the pipe winding disc 12 to rotate in the opposite direction as well. This rewinds the previously released water supply pipe back onto the pipe winding disc 12, achieving automatic rewinding of the water supply pipe. The entire rewinding process remains orderly and effectively avoids the problem of the water supply pipe getting tangled or knotted during the device's movement, ensuring that the water supply pipe maintains a good working condition at different stages of irrigation operations.

[0029] Depending on the different growth stages of alfalfa or its post-harvest state, the user can send a height adjustment command to the electric cylinder 807 in the telescopic assembly 8 via the controller. Since the two ends of the electric cylinder 807 are fixedly connected to the lower connector 805 on the wall of the fixed pipe 801 and the upper connector 806 on the wall of the movable pipe 802, when the electric cylinder 807 receives the extension command, its piston rod extends, pushing the upper connector 806 upwards. This, in turn, causes the movable pipe 802, fixed to the upper connector 806, to slide upwards within the fixed pipe 801. The upper end of the movable pipe 802 is connected to the spraying assembly 9 via a connector 803, a lower flange 804, and an upper flange 901, thereby... The spraying assembly 9 is pushed upward to raise the height of the nozzle 905 to accommodate alfalfa at a higher growth stage. When the electric cylinder 807 receives a shortening command, its piston rod retracts, pulling the upper connector 806 downward, causing the movable tube 802 to slide downward within the fixed tube 801, thereby pulling the spraying assembly 9 downward to lower the height of the nozzle 905 to accommodate the shorter plant size after alfalfa cutting or in the early stages of growth, ensuring that the nozzle 905 is always in the optimal irrigation position to match the growth height of the alfalfa.

[0030] When the water supply pipe delivers water from an external water source to the spray assembly 9, the water flow first enters the spray bar 904 connected to the end of the water supply pipe away from the coil 12. Since the end of the spray bar 904 is blocked, the water flow is evenly distributed inside the spray bar 904. Finally, through multiple nozzles 905 set on the lower wall of the spray bar 904, the water is evenly sprayed onto the alfalfa plants below in a water-saving form such as atomization or drip irrigation, thus completing the water-saving irrigation operation for the alfalfa. While ensuring the irrigation effect, the water waste is minimized.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
