[0032] 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 some embodiments of this utility model, but not all embodiments. Example

[0033] like Figures 1 to 12 The illustrated farmland irrigation device includes a rigid water pipe 1, a frame 2, a water pipe reel support 3 mounted on the frame 2, and a water pipe winding mechanism 4 mounted on the water pipe reel support 3. The water pipe winding mechanism 4 includes a support cylinder 401, a shaft tube 402, multiple retaining rings 403, and an external gear ring 404. The shaft tube 402 passes through the axis of the support cylinder 401 and is fixedly connected to the support cylinder 401. Both ends of the shaft tube 402 extend to the outside of the support cylinder 401 and are rotatably mounted on the top of the water pipe reel support 3 via bearings. Multiple retaining rings 403 are evenly spaced along the circumference of the support cylinder 401 on both sides of the support cylinder 401. The external gear ring 404 has a diameter less than or equal to the inner diameter of the support cylinder 401 and is fixedly mounted on the end face of one end of the support cylinder 401. It is connected to the drive mechanism 5 via a transmission structure to drive the support cylinder 401 to rotate. A bidirectional pipe laying device 6 for placing the rigid water pipe 1 is provided on the bottom side of the water pipe reel support 3 near the rear of the frame 2.

[0034] Using a rigid water pipe 1 ensures that the cross-section of the rigid water pipe 1 does not change during the process of winding and unwinding the water pipe, and the water pressure remains constant to avoid pump blockage. However, due to the high structural strength of the rigid water pipe 1, a larger torque is required when winding and unwinding the rigid water pipe. By using a drive mechanism 5 to drive a large-sized external gear ring 404 with a diameter close to that of the support cylinder 401 with a small gear, the torque is increased by deceleration, and the output force is amplified to improve the efficiency of the water pipe winding mechanism 4 in winding and unwinding the rigid water pipe 1.

[0035] One end of the shaft tube 402 is closed, and the other end extends from inside the bearing to the outside for a certain length and is provided with a water inlet pipe 405 to connect to an external water source. The shaft tube 402 is located inside the support cylinder 401 and has a water outlet on the side wall near the closed end of the shaft tube 401. A water outlet pipe is provided at the water outlet. One end of the water outlet pipe is connected to the water outlet, and the other end extends from the shaft tube toward the circumferential surface of the support cylinder 401 to the outside of the circumferential surface of the support cylinder 401. One end of the rigid water pipe 1 is connected to the water outlet pipe and is partially wrapped around the circumferential surface of the support cylinder 401. The other end is opened and closed by the bidirectional pipe drainer 6 for irrigation.

[0036] The drive mechanism 5 includes a power supply 501, a drive motor 502, a reducer 503, and a controller. The power supply 501 is mounted on the frame 2. The drive motor 502 is electrically connected to the power supply 501 through the controller, which is used to control the operation of the drive motor 502. The input end of the reducer 503 is connected to the drive motor 502 through a transmission chain, and the output end of the reducer 503 is connected to the external gear ring 404 through a transmission structure.

[0037] The transmission structure is a transmission chain, which is mounted on the outer gear ring 404. The inner diameter of the outer gear ring 404 is less than or equal to the length of the inner diameter of the support cylinder 401.

[0038] The bidirectional hose reel 6 includes a reciprocating screw 601, a slide rod 602, a hose reel fork 603, a drive gear 604, and a driven gear 605. The reciprocating screw 601 is rotatably mounted on the rear of the frame 2 below the hose winding mechanism 4, and the driven gear 605 is mounted on one end of the screw 601. The slide rod 602 is parallel to the reciprocating screw 601. The hose reel fork 603 is mounted on the slide rod 602 and the reciprocating screw 601. The drive gear 604 is positioned correspondingly to the driven gear 605. On the shaft tube 402, the driving gear 604 and the driven gear 605 are connected by a transmission chain. The driving gear 604 drives the driven gear 605 to rotate, and the driven gear 605 drives the reciprocating screw 601 to rotate synchronously. The reciprocating screw 601 drives the pipe fork 603 to move back and forth. The part of the rigid water pipe 1 extending out of the water pipe winding mechanism 4 is set on the pipe fork 603 and is arranged in an orderly manner on the water pipe winding mechanism 4 under the drive of the pipe fork 603.

[0039] By using a two-way pipe arranger 6 to automatically arrange rigid water pipes 1, the labor intensity of farmers who have to drag and place rigid water pipes 1 during watering is reduced.

[0040] The frame 2 includes a triangular or trapezoidal frame chassis 201, a steering mechanism 202, a power unit, and a seat 203. Rear wheels 204 are rotatably mounted on both sides of the rear of the frame chassis 201 via shock absorber axles. The power unit is located in the middle of the frame chassis 201 and drives the two rear wheels 204 to rotate via a drive axle. The seat 203 is located at the front of the frame chassis 201 and above the power unit. A steering beam 205 with a forward and upward tilt and a certain length is provided in the middle of the front end of the frame chassis 201. The steering mechanism 202 includes a steering wheel 2021, a front fork 2022, a power assist structure 2023, and a steering wheel 2024 or a handlebar. The steering wheel 2021 is rotatably mounted at the bottom of the front fork 2022 via a pivot. The front fork 2022 is mounted through the front end of the steering beam 205 via a pivot. The top of the front fork 2022 is connected to the steering wheel 2024 or the handlebar via the power assist structure 2023.

[0041] Because of the stability provided by the three-point support, the three-wheeled vehicle is better able to adapt to the rugged terrain of farmland, thus improving the adaptability of this invention to unpaved farmland surfaces.

[0042] The power assist structure 2023 includes a power assist arm 20231 and a power assist internal gear ring 20232. The power assist arm 20231 is located at the top front end of the steering beam 205. A connecting rod 20241 is located at the bottom of the steering wheel 2024. The connecting rod 20241 is rotatably mounted on one side of the power assist arm 20231 via a rotating shaft. A gear 20242 is located at the bottom of the connecting rod 20241. The power assist internal gear ring 20232 includes a semi-circular D-shaped internal gear ring with an internal slot. The inner side of the semi-circular arc portion of the power assist internal gear ring 20232 has continuous teeth. The power assist internal gear ring 20232 is fitted onto the power assist arm 20321 with its internal slot area and is fixedly connected to the top of the front fork 2022 with its semi-circular straight portion. The gear 20242 at the bottom of the connecting rod 20241 engages with the teeth of the power assist internal gear ring 20232.

[0043] When the farmer turns the steering wheel 2024, the gear 20242 connected to the bottom of the steering wheel 2024 via the connecting rod 20241 rotates synchronously. As the gear 20242 engages with the gear ring 20232, the gear ring 20232 is driven to rotate by the gear 20242, thereby twisting the front fork 2022, changing the direction of the steering wheel 2021, and thus changing the direction of travel of this utility model.

[0044] The rear wheels (204) and steering wheels (2021) are both solid anti-skid tires.

[0045] A hose winch 7 is provided on the side of the frame 2 behind the seat 203 near the water inlet pipe of the axle tube 402, for storing the hose connecting the external water source to the water inlet pipe 405 of this utility model.

[0046] Workflow: First, drive the locomotive to the farmland requiring irrigation. Select the appropriate sprinkler tractor based on the height of the crops, choose the direction of irrigation, and place the sprinkler tractor. The farmer then starts the hose reel mechanism 4 to release the rigid hose 1 via the bidirectional hose reel 6, connecting the rigid hose 1 to the sprinkler tractor. The farmer then connects the hose reel mechanism 4 to an external water source. After connecting the external water source, the farmer starts the hose reel mechanism 4 to reel in the rigid hose 1, beginning irrigation of the farmland. The rigid hose 1 gradually shortens while continuously irrigating until the outlet of the rigid hose 1 is close to the locomotive, completing the irrigation of the farmland. The farmer then moves to a different location and continues the above operation until the entire plot of land is irrigated. Finally, the external water source is turned off, completing the operation.

[0047] Finally, it should be noted that the above-described 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 or all of the technical features therein.
