Description

Technical Field

[0001] This utility model relates to a self-propelled sprinkler irrigation machine. Background Technology

[0002] Currently, reel-type sprinkler irrigation machines are widely used in agricultural sprinkler irrigation. For example, Chinese patent CN215122895U discloses a reel-type sprinkler irrigation machine. Existing reel-type sprinkler irrigation machines require a tractor to tow them to the location to be irrigated, and then the tractor must tow the sprinkler head to a location away from the reel before irrigation can begin. Therefore, existing reel-type sprinkler irrigation machines must be equipped with a tractor for towing to carry out sprinkler operations, which is very inconvenient in actual use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a self-propelled sprinkler irrigation machine that can complete sprinkler irrigation without relying on tractor towing, making it more convenient to use.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a self-propelled sprinkler irrigation machine, including a sprinkler truck, a reel, a central tube, a water supply pipe, a connecting pipe, a spray gun, an anchoring mechanism, a winding drive mechanism, and a walking drive mechanism.

[0005] The reel is rotatably mounted on the sprinkler truck;

[0006] The central tube is connected to the reel and is coaxially arranged with the reel;

[0007] The water supply pipe is wound and connected to the reel, the outlet end of the water supply pipe is connected to the central pipe, and the inlet end of the water supply pipe is used to connect to a water source.

[0008] The winding drive mechanism is installed on the sprinkler truck and connected to the reel. The winding drive mechanism is used to drive the reel to rotate so that the reel winds up the water supply pipe and causes the reel to drive the central pipe to rotate together.

[0009] The spray gun is connected to the sprinkler truck;

[0010] One end of the connecting pipe is connected to the spray gun, and the other end of the connecting pipe is connected to the central pipe through a rotary joint;

[0011] The anchoring mechanism is used to fix the inlet end of the water supply pipe so that the inlet end of the water supply pipe remains in a fixed position;

[0012] The walking drive mechanism is connected to the sprinkler truck and is used to drive the sprinkler truck to move.

[0013] Further, a specific structure of the sprinkler truck is provided, the sprinkler truck including a vehicle body, front wheels and rear wheels;

[0014] The front wheels and the rear wheels are respectively connected to the vehicle body;

[0015] The walking drive mechanism is connected to the vehicle body and connected to the rear wheels, and is used to drive the rear wheels to rotate so as to move the sprinkler truck.

[0016] Further, a specific structure of the walking drive mechanism is provided, the walking drive mechanism including a walking motor, a differential, a first driving wheel, a second driving wheel, a first driven wheel, a second driven wheel, a first transmission component, and a second transmission component;

[0017] The vehicle has two rear wheels, one of which is rotatably connected to the left side of the vehicle body and the other is rotatably connected to the right side of the vehicle body.

[0018] Both the travel motor and the differential are connected to the vehicle body;

[0019] The first drive wheel is connected to the first output shaft of the differential, the first driven wheel is connected to one of the rear wheels, and the first transmission component is connected to the first drive wheel and the first driven wheel;

[0020] The second drive wheel is connected to the second output shaft of the differential, the second driven wheel is connected to another rear wheel, and the second transmission component is connected to the second drive wheel and the second driven wheel;

[0021] The walking motor is connected to the input shaft of the differential and is used to drive the input shaft of the differential to rotate, thereby driving the first output shaft and the second output shaft of the differential to rotate. When the first output shaft rotates, it is used to drive the first drive wheel to rotate, thereby driving the first driven wheel and the corresponding rear wheel to rotate through the first transmission component. When the second output shaft rotates, it is used to drive the second drive wheel to rotate, thereby driving the second driven wheel and the corresponding rear wheel to rotate through the second transmission component.

[0022] Furthermore, the sprinkler truck also includes a lifting mechanism and guide wheels;

[0023] The guide wheel is connected to the lifting mechanism and is located above the water pipe being unwound from the reel to the ground;

[0024] The lifting mechanism is connected to the vehicle body. The lifting mechanism is used to drive the guide wheel down to press on the water pipe that is unwound to the ground and to lift the front end of the vehicle body upward so that the front wheel is suspended in the air. The lifting mechanism is also used to drive the guide wheel up to disengage from the water pipe that is unwound to the ground so that the front wheel touches the ground.

[0025] When the guide wheel presses on the water pipe that has been unwound to the ground and the front wheel is suspended in the air, the winding drive mechanism drives the reel to rotate to wind up the water pipe, thereby pulling the sprinkler truck through the water pipe and causing the guide wheel pressing on the water pipe to move along the water pipe.

[0026] Furthermore, the front wheel is located between the guide wheel and the rear wheel, and the lifting mechanism is connected to the front end of the vehicle body.

[0027] Further, a specific structure of the lifting mechanism is provided, wherein the lifting mechanism includes a support arm, a lifting nut, and a lifting screw;

[0028] The support arm is slidably and vertically connected to the vehicle body, and the guide wheel is rotatably connected to the lower end of the support arm;

[0029] The lifting nut is connected to the support arm;

[0030] The lifting screw is rotatably connected to the vehicle body and is engaged with the lifting nut. The lifting screw is driven to rotate, thereby driving the lifting nut and the support arm to move up and down.

[0031] Furthermore, the self-propelled sprinkler also includes limit switches and a controller;

[0032] The limit switch is connected to the lower end of the support arm and to the controller. The limit switch is used to trigger the anchoring mechanism and generate a signal to the controller when the guide wheel moves along the water pipe toward the water inlet end of the water pipe.

[0033] The controller is connected to the winding drive mechanism and is used to control the winding drive mechanism to stop working when it receives a signal sent by the limit switch.

[0034] Further, a specific structure of the winding drive mechanism is provided, wherein the winding drive mechanism includes a winding motor, a gearbox, a winding drive wheel, a winding driven wheel, and winding transmission components;

[0035] Both the winding motor and the gearbox are mounted on the vehicle body;

[0036] The winding drive pulley is connected to the output shaft of the gearbox;

[0037] The winding driven wheel is connected to the reel;

[0038] The winding drive component is connected to the winding drive wheel and the winding driven wheel;

[0039] The take-up motor is connected to the input shaft of the gearbox and is used to drive the gearbox to rotate, thereby driving the take-up drive wheel to rotate through the take-up transmission component, and in turn driving the reel to rotate to take up the water pipe.

[0040] Furthermore, the self-propelled sprinkler also includes a disengagement contact mechanism, which includes a first lever, a second lever, a first connecting rod, and a second connecting rod.

[0041] The first lever and the second lever are respectively rotatably connected to the vehicle body;

[0042] The front end of the first connecting rod is hinged to the first lever, and the rear end of the first connecting rod is hinged to the second lever;

[0043] The front end of the second link is hinged to the second lever, and the rear end of the second link is connected to the shift lever on the gearbox;

[0044] The lower end of the first lever is provided with a contact part, which is used to abut against the anchoring mechanism when the guide wheel travels along the water pipe toward the water inlet end of the water pipe to drive the first lever to rotate, thereby driving the second lever to rotate through the first connecting rod, and then driving the shift lever to move through the second connecting rod to put the gearbox into neutral.

[0045] Further, a specific structure of the anchoring mechanism is provided, the anchoring mechanism including a ground anchor and a blocking block;

[0046] The blocking block is connected to the inlet end of the water supply pipe and protrudes outward in a radial direction;

[0047] The ground anchor is used to hold the water inlet end of the water pipe in place, insert it into the ground, and press against the blocking block to fix the water inlet end of the water pipe.

[0048] After adopting the above technical solution, the sprinkler truck is first driven to the location where it needs to be sprinkled by the walking drive mechanism. Then, the water inlet end of the water pipe is connected to the water pump and the water inlet end of the water pipe is fixed by the anchoring mechanism to keep the water inlet end of the water pipe in a fixed position. Then, the winding drive mechanism is deactivated and the walking drive mechanism is activated to drive the sprinkler truck to move away from the water inlet end of the water pipe. Because the water inlet end of the water pipe is fixed in a fixed position, the water pipe will be pulled and unwound from the reel when the sprinkler truck moves away from the water inlet end of the water pipe. The unwound water pipe will fall to the ground. Once the sprinkler truck reaches the designated location, the water delivery pipe is unwound. The driving mechanism is then turned off, and the water pump is activated to draw water sequentially through the water delivery pipe, the central pipe, the rotary joint, the connecting pipe, and the spray gun before being sprayed out for irrigation. At this point, the winding mechanism is activated to rotate the reel, winding the water delivery pipe onto it. Because the inlet end of the water delivery pipe is fixed in place, the rewinding process pulls the sprinkler truck towards the inlet end, allowing irrigation to proceed through the spray gun. In this embodiment, the driving mechanism enables the sprinkler truck to move autonomously across the field to the desired irrigation location and to unwound the water delivery pipe, allowing irrigation to be completed without tractor traction, making it more convenient in actual use.

[0057] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0058] like Figures 1-7 As shown, a self-propelled sprinkler irrigation machine includes a sprinkler truck 1, a reel 2, a central pipe 3, a water supply pipe 4, a connecting pipe 5, a spray gun 6, an anchoring mechanism 7, a winding drive mechanism, and a walking drive mechanism.

[0059] The reel 2 is rotatably mounted on the sprinkler truck 1;

[0060] The central tube 3 is connected to the reel 2 and is coaxially arranged with the reel 2;

[0061] The water supply pipe 4 is wound and connected to the reel 2. The outlet end of the water supply pipe 4 is connected to the central pipe 3. The inlet end 49 of the water supply pipe 4 is used to connect to a water source.

[0062] The winding drive mechanism is installed on the sprinkler truck 1 and connected to the reel 2. The winding drive mechanism is used to drive the reel 2 to rotate so that the reel 2 winds up the water pipe 4 and causes the reel 2 to drive the central pipe 3 to rotate together.

[0063] The spray gun 6 is connected to the sprinkler truck 1;

[0064] One end of the connecting pipe 5 is connected to the spray gun 6, and the other end of the connecting pipe 5 is connected to the central pipe 3 through the rotary joint 8, so that the water flow can enter from the inlet end 49 of the water supply pipe 4 and then flow through the water supply pipe 4, the central pipe 3, the rotary joint 8 and the connecting pipe 5 in sequence before flowing into the spray gun 6 and being sprayed out.

[0065] The anchoring mechanism 7 is used to fix the water inlet end 49 of the water pipe 4 so that the water inlet end 49 of the water pipe 4 remains in a fixed position.

[0066] The walking drive mechanism is connected to the sprinkler truck 1 and is used to drive the sprinkler truck 1 to move.

[0067] Specifically, firstly, the walking drive mechanism drives the sprinkler truck 1 to the location where irrigation is needed. Then, the inlet end 49 of the water pipe 4 is connected to the water pump, and the inlet end 49 of the water pipe 4 is fixed by the anchoring mechanism 7 to keep the inlet end 49 of the water pipe 4 in a fixed position. Then, the winding drive mechanism is deactivated and the walking drive mechanism is activated to drive the sprinkler truck 1 to move away from the inlet end 49 of the water pipe 4. Because the inlet end 49 of the water pipe 4 is fixed in a fixed position, the water pipe 4 will be pulled and unwound from the reel 2 when the sprinkler truck 1 moves away from the inlet end 49 of the water pipe 4. The unwound water pipe 4 will fall to the ground. Once the sprinkler truck 1 reaches the designated position, the water supply pipe 4 is unwound. The driving mechanism is then turned off, and the water pump is activated to draw water sequentially through the water supply pipe 4, the central pipe 3, the rotary joint 8, the connecting pipe 5, and the spray gun 6 before being sprayed out from the spray gun 6 for irrigation. At this point, the winding mechanism is activated to rotate the reel 2, winding the water supply pipe 4 onto the reel 2. Since the inlet end 49 of the water supply pipe 4 is fixed in place, the water supply pipe 4 pulls the sprinkler truck 1 towards the inlet end 49 during winding, allowing irrigation to proceed through the spray gun 6. In this embodiment, the driving mechanism allows the sprinkler truck 1 to move independently across the field to the desired irrigation location, and it can also move independently across the field to unwind the water supply pipe 4. This allows for irrigation operations without relying on a tractor, making it more convenient in actual use. The specific structure of the spray gun 6 is existing technology well known to those skilled in the art, and will not be described in detail in this embodiment.

[0068] like Figures 1-3 As shown, the sprinkler truck 1 may include a vehicle body 9, front wheels 10 and rear wheels 11;

[0069] The front wheel 10 and the rear wheel 11 are respectively connected to the vehicle body 9;

[0070] The walking drive mechanism is connected to the vehicle body 9 and connected to the rear wheel 11, and is used to drive the rear wheel 11 to rotate so as to drive the irrigation vehicle 1 to move. Specifically, the front wheel 10 can be a steering wheel, and the front wheel 10 is steerably connected to the vehicle body 9. The irrigation vehicle 1 is also provided with a steering wheel and a vehicle steering mechanism to control the steering of the front wheel 10. The specific structures of the steering wheel and the vehicle steering mechanism are existing technologies well known to those skilled in the art, and will not be described in detail in this embodiment. In this embodiment, the spray gun 6 and the winding drive mechanism are also respectively connected to the vehicle body 9, and the reel 2 is rotatably mounted on the vehicle body 9. In this embodiment, the central tube 3 can be coaxially fixedly connected to the reel 2, and the two ends of the central tube 3 can be rotatably connected to the vehicle body 9 of the irrigation vehicle 1 through bearings, so that the reel 2 and the central tube 3 are both rotatably mounted on the vehicle body 9.

[0071] like Figures 1-3 As shown, the walking drive mechanism may include a walking motor 12, a differential 13, a first drive wheel 14, a second drive wheel 15, a first driven wheel 16, a second driven wheel 17, a first transmission component 18, and a second transmission component 19.

[0072] The rear wheel 11 is provided in two parts, one of which is rotatably connected to the left side of the vehicle body 9, and the other of which is rotatably connected to the right side of the vehicle body 9.

[0073] Both the walking motor 12 and the differential 13 are connected to the vehicle body 9;

[0074] The first drive wheel 14 is connected to the first output shaft 20 of the differential 13, the first driven wheel 16 is connected to one of the rear wheels 11, and the first transmission component 18 is connected to the first drive wheel 14 and the first driven wheel 16.

[0075] The second drive wheel 15 is connected to the second output shaft 21 of the differential 13, the second driven wheel 17 is connected to another rear wheel 11, and the second transmission component 19 is connected to the second drive wheel 15 and the second driven wheel 17;

[0076] The walking motor 12 is connected to the input shaft of the differential 13 and is used to drive the input shaft of the differential 13 to rotate, thereby driving the first output shaft 20 and the second output shaft 21 of the differential 13 to rotate. When the first output shaft 20 rotates, it drives the first drive wheel 14 to rotate, which in turn drives the first driven wheel 16 and the corresponding rear wheel 11 to rotate through the first transmission component 18. When the second output shaft 21 rotates, it drives the second drive wheel 15 to rotate, which in turn drives the second driven wheel 17 and the corresponding rear wheel 11 to rotate through the second transmission component 19, thereby driving the sprinkler truck 1 to move. Specifically, the specific structure of the differential 13 is prior art well known to those skilled in the art, and will not be described in detail in this embodiment. In this embodiment, the first drive wheel 14, the second drive wheel 15, the first driven wheel 16 and the second driven wheel 17 can all be sprockets, and the first transmission component 18 and the second transmission component 19 can both be chains. Of course, in some embodiments, the walking drive mechanism may also include a first wheel-side motor and a second wheel-side motor, the first wheel-side motor being connected to the vehicle body 9 and drivingly connected to one of the rear wheels 11, and the second wheel-side motor being connected to the vehicle body 9 and drivingly connected to the other rear wheel 11.

[0077] like Figure 1 , 2 As shown in Figures 3 and 5, the sprinkler truck 1 may also include a lifting mechanism 22 and guide wheels 23;

[0078] The guide wheel 23 is connected to the lifting mechanism 22 and is located above the water pipe 4 that is unwound from the reel 2 to the ground;

[0079] The lifting mechanism 22 is connected to the vehicle body 9. The lifting mechanism 22 is used to drive the guide wheel 23 to descend and press against the water pipe 4 unwound to the ground, and to lift the front end of the vehicle body 9 upward, thereby suspending the front wheel 10 in the air. The lifting mechanism 22 is also used to drive the guide wheel 23 to rise upward until it is disengaged from the water pipe 4 unwound to the ground, thereby allowing the front wheel 10 to touch the ground. In this embodiment, the guide wheel 23 can be a V-shaped wheel.

[0080] When the guide wheel 23 presses on the water pipe 4 that has been unwound to the ground and the front wheel 10 is suspended in the air, the winding drive mechanism drives the reel 2 to rotate to wind up the water pipe 4, thereby pulling the sprinkler truck 1 to move through the water pipe 4, and causing the guide wheel 23 pressing on the water pipe 4 to move along the water pipe 4.

[0081] Specifically, first, the front wheels 10 are brought to the ground, and the sprinkler truck 1 is driven by the walking drive mechanism to the location where irrigation is needed. Then, the inlet end 49 of the water pipe 4 is connected to the water pump, and the inlet end 49 of the water pipe 4 is fixed by the anchoring mechanism 7 to keep the inlet end 49 of the water pipe 4 in a fixed position. Then, the front wheels 10 are brought to the ground again, the winding drive mechanism is not activated, and the walking drive mechanism is activated to drive the sprinkler truck 1 to move away from the inlet end 49 of the water pipe 4. Because the inlet end 49 of the water pipe 4 is fixed in position, the water pipe 4 will be pulled away from the reel 2 and unwound as the sprinkler truck 1 moves away from the inlet end 49 of the water pipe 4. The unwound water pipe 4 will fall to the ground. After the sprinkler truck 1 reaches the designated position, the water supply pipe 4 is unwound. Then, the driving mechanism is turned off, and the guide wheel 23 is driven by the lifting mechanism 22 to descend onto the water supply pipe 4 that has been unwound to the ground, thus lifting the front end of the vehicle body 9 and suspending the front wheel 10 in the air. Then, the water pump is turned on to pump water so that the water flows sequentially through the water supply pipe 4, the central pipe 3, the rotary joint 8, the connecting pipe 5, and the spray gun 6 before being sprayed out from the spray gun 6 for irrigation. At this time, the winding driving mechanism is activated to drive the reel 2 to rotate. The water pipe 4 is then wound onto the reel 2. Since the inlet end 49 of the water pipe 4 is fixed in place, the water pipe 4 pulls the irrigation vehicle 1 towards the inlet end 49 during the winding process. At this time, the rear wheel 11 is on the ground, the front wheel 10 is suspended in the air, and the guide wheel 23 is pressed on the water pipe 4 on the ground and moves along the water pipe 4. The guide wheel 23 can adjust its forward direction at any time along the direction of the water pipe 4 to prevent the irrigation vehicle 1 from deviating. The spray gun 6 can spray water along the way as the irrigation vehicle 1 moves. After the irrigation is finished, the lifting mechanism 22 drives the guide wheel 23 to rise up until it is detached from the water pipe 4 that has been unwound to the ground, so that the front wheel 10 touches the ground. Then, the anchoring mechanism 7 releases the fixation of the water pipe 4, detaching the water pipe 4 from the water pump. Then, the walking drive mechanism can be started to drive the irrigation vehicle 1 to the next location that needs irrigation.

[0082] like Figures 1-3 As shown, the front wheel 10 is located between the guide wheel 23 and the rear wheel 11, and the lifting mechanism 22 is connected to the front end of the vehicle body 9.

[0083] like Figure 5 As shown, the lifting mechanism 22 may include a support arm 24, a lifting nut 25, and a lifting screw 26;

[0084] The support arm 24 is slidably connected to the vehicle body 9, and the guide wheel 23 is rotatably connected to the lower end of the support arm 24;

[0085] The lifting nut 25 is connected to the support arm 24;

[0086] The lifting screw 26 is rotatably connected to the vehicle body 9 and engages with the lifting nut 25. The lifting screw 26 is driven to rotate, thereby causing the lifting nut 25 and the support arm 24 to move up and down, which in turn causes the guide wheel 23 to rise and fall. Specifically, the lifting screw 26 can be driven to rotate by a motor or manually by a handle; more specifically, the front end of the vehicle body 9 is provided with a sliding sleeve 27, and the support arm 24 is slidably connected in the sliding sleeve 27, which is part of the vehicle body 9.

[0087] like Figure 1 , 2 As shown in Figures 3 and 5, the self-propelled sprinkler may also include a limit switch 28 and a controller;

[0088] The limit switch 28 is connected to the lower end of the support arm 24 and connected to the controller. The limit switch 28 is used to trigger the anchoring mechanism 7 and generate a signal to the controller when the guide wheel 23 moves along the water pipe 4 toward the water inlet 49 of the water pipe 4.

[0089] The controller is connected to the winding drive mechanism and is used to control the winding drive mechanism to stop working when it receives a signal from the limit switch 28, thereby causing the reel 2 to stop winding the water supply pipe 4, and thus causing the sprinkler truck 1 to stop moving, thus ending the sprinkler irrigation process. The controller can be installed on the vehicle body 9.

[0090] like Figure 2 , 3 As shown, the winding drive mechanism may include a winding motor 29, a gearbox 30, a winding drive wheel 31, a winding driven wheel 32, and a winding transmission component 33;

[0091] Both the winding motor 29 and the gearbox 30 are mounted on the vehicle body 9;

[0092] The winding drive wheel 31 is connected to the output shaft of the gearbox 30;

[0093] The winding driven wheel 32 is connected to the reel 2;

[0094] The winding drive component 33 is connected to the winding drive wheel 31 and the winding driven wheel 32;

[0095] The take-up motor 29 is connected to the input shaft of the gearbox 30 and drives the gearbox 30 to rotate the take-up drive wheel 31, which in turn drives the take-up driven wheel 32 to rotate via the take-up transmission component 33, thereby driving the reel 2 to rotate and take up the water pipe 4. When the reel 2 rotates, it also drives the center pipe 3 to rotate. The take-up transmission component 33 can be a chain, and both the take-up drive wheel 31 and the take-up driven wheel 32 can be sprockets. The controller is connected to the take-up motor 29 in the take-up drive mechanism and controls the take-up motor 29 to stop operating when it receives a signal from the limit switch 28.

[0096] like Figure 2 , 3 As shown in Figure 6, the self-propelled sprinkler may further include a disengagement contact mechanism, which may include a first lever 34, a second lever 35, a first connecting rod 36, and a second connecting rod 37.

[0097] The first lever 34 and the second lever 35 are respectively rotatably connected to the vehicle body 9;

[0098] The front end of the first connecting rod 36 is hinged to the first lever 34, and the rear end of the first connecting rod 36 is hinged to the second lever 35.

[0099] The front end of the second link 37 is hinged to the second lever 35, and the rear end of the second link 37 is connected to the shift lever 38 on the gearbox 30;

[0100] The lower end of the first lever 34 is provided with a contact part 39. The contact part 39 is used to abut against the anchoring mechanism 7 when the guide wheel 23 moves along the water pipe 4 toward the water inlet 49 of the water pipe 4 to drive the first lever 34 to rotate. Then, through the first connecting rod 36, the second lever 35 is driven to rotate. Then, through the second connecting rod 37, the shift lever 38 is driven to move so that the gearbox 30 is put into neutral. Thus, the gearbox 30 can be automatically put into neutral after the irrigation ends.

[0101] like Figure 2 , 3 As shown in Figures 7 and 8, the anchoring mechanism 7 may include a ground anchor 40 and a blocking block 41;

[0102] The blocking block 41 is connected to the water inlet end 49 of the water pipe 4 and protrudes outward in a radial direction;

[0103] The ground anchor 40 is used to fork the water inlet end 49 of the water pipe 4, insert it into the ground, and abut against the blocking block 41 to fix the water inlet end 49 of the water pipe 4, thereby keeping the water inlet end 49 of the water pipe 4 in a fixed position; in this embodiment, the limit switch 28 is used to be triggered and generate a signal after abutting against the ground anchor 40 in the anchoring mechanism 7, and the contact part 39 is used to drive the first lever 34 to rotate after abutting against the ground anchor 40 in the anchoring mechanism 7. Figure 7 As shown, the ground anchor 40 includes a left fork leg 42, a right fork leg 43, and an opening groove 44 located between the left fork leg 42 and the right fork leg 43. The opening groove 44 is used to hold the water inlet end 49 of the water supply pipe 4. The left fork leg 42 and the right fork leg 43 are respectively used to insert into the ground, thereby causing the ground anchor 40 to hold the water inlet end 49 of the water supply pipe 4 and abut against the blocking block 41.

[0104] In this embodiment, the water supply pipe 4 can be a PE pipe. The vehicle body 9 can also be equipped with a seat 45, a battery 46, and a range extender 47. The range extender 47 is used to charge the battery 46, and the battery 46 is used to power the winding motor 29 and the travel motor 12. The vehicle body 9 can also be connected to a guide device 48 for guiding the water supply pipe 4 as it winds onto the reel 2. The guide device 48 can be the guide device described in Chinese Patent Publication No. CN214155722U.

[0105] In summary, firstly, the walking drive mechanism drives the sprinkler truck 1 to the location where irrigation is needed. Then, the inlet end 49 of the water pipe 4 is connected to the water pump, and the inlet end 49 of the water pipe 4 is fixed by the anchoring mechanism 7 to keep the inlet end 49 of the water pipe 4 in a fixed position. Then, the winding drive mechanism is deactivated and the walking drive mechanism is activated to drive the sprinkler truck 1 to move away from the inlet end 49 of the water pipe 4. Because the inlet end 49 of the water pipe 4 is fixed in a fixed position, the water pipe 4 will be pulled and unwound from the reel 2 when the sprinkler truck 1 moves away from the inlet end 49 of the water pipe 4. The unwound water pipe 4 will fall to the ground. After the sprinkler truck 1 reaches the designated position, the water supply pipe 4 is unwound. Then, the driving mechanism is turned off and the water pump is turned on to draw water, allowing the water to flow sequentially through the water supply pipe 4, the central pipe 3, the rotary joint 8, the connecting pipe 5, and the spray gun 6 before being sprayed out from the spray gun 6 for irrigation. At this time, the winding mechanism is activated to drive the reel 2 to rotate, thereby winding the water supply pipe 4 onto the reel 2. Since the inlet end 49 of the water supply pipe 4 is fixed in position, the water supply pipe 4 pulls the sprinkler truck 1 towards the inlet end 49 during winding, thus enabling irrigation through the spray gun 6. In this embodiment, the driving mechanism can drive the sprinkler truck 1 to move independently between fields to the required irrigation location, and it can also drive the sprinkler truck 1 to move independently between fields to unwound the water supply pipe 4. This allows for irrigation operations without relying on a tractor, making it more convenient in actual use.
