The specific meaning of the above terms in the present application can be understood by those skilled in the art according to the specific circumstances.

Referring to fig. 1, the present embodiment provides a self-walking reel type sprinkler, which comprises a sprinkler host 1, a sprinkler vehicle 2, a counterweight adjusting water tank 201 and a controller (not shown in the figure), wherein the sprinkler vehicle 2 is connected with the sprinkler host 1 through a PE pipe 109, the PE pipe 109 is placed on a reel 103 of the sprinkler host 1, and the PE pipe 109 on the reel 103 is driven to be retracted and extended by a water turbine box 106. In actual use, the driving part of the remote control spray head vehicle 2 is started by the controller, and the spray head vehicle 2 is driven by the driving part to move to a specified working position. When the spray head vehicle 2 moves, as the moving distance of the spray head vehicle 2 is more and more far away from the spray irrigation host 1, the required ground grabbing force of the spray head vehicle 2 is more and more large, so that the control valve 2013 in the water tank needs to be remotely controlled by the controller to be opened, and meanwhile, water is injected into the snakelike coil 2012 in the counterweight adjusting water tank 201 from the bottom layer, so that the weight of the spray head vehicle 2 is gradually increased, the ground grabbing force of the spray head vehicle 2 is further improved, and the automatic walking capability of the spray head vehicle 2 is improved.

Furthermore, in order to facilitate the remote control of the automatic walking of the spray head vehicle 2, it should be noted that the controller may adopt a remote controller, a remote control handle, or a computer control provided with a corresponding program.

Further, the sprinkler host 1 comprises a frame 101, a reel 103 rotatably arranged on the frame 101, and a water turbine box 106 and a gearbox 104 are arranged for driving the reel 103 to rotate slowly and realizing slow recovery of the PE pipe 109. The gearbox 104 is in transmission connection with the water turbine box 106, the water turbine box 106 is used for providing power for rotation of the reel 103, and meanwhile the gearbox 104 can change rapid rotation of the water turbine box 106 into slow rotation, so that the reel 103 can slowly recover the PE pipe 109. It should be noted that, the water turbine box 106 is connected with the water inlet pipe 105, the water inlet pipe 105 is used for the external water source, and since the external water source is conveyed by the external conveying pump, the external water source has a certain impact force when entering the water inlet pipe 105, and the turbine component inside the water turbine box 106 is driven to rotate by the impact force, so that the turbine component outputs power to the gearbox 104, the gearbox 104 changes speed, and finally the reel 103 rotates to provide power.

Further, it is understood that the sprinkler 1 may not adopt a driving mode of the water turbine box 106, and the rotation of the reel 103 may be realized by adding the motor 206 and a speed reducer matched with the motor. The specific driving mode is adopted according to the actual working requirement.

Further, the spray head vehicle 2 comprises a movable frame 205, wheels 203 are arranged on the movable frame 205, and in order to meet the requirements of the terrain, the wheels 203 are wide wheels 203, so that the pressure of the wheels 203 to the ground is reduced, the wheels 203 are prevented from sinking below the ground surface layer, and the walking capacity of the spray head vehicle 2 is improved. The movable frame 205 is also provided with a supporting frame for fixing the spray head 208, so that the spray head 208 is prevented from falling off during spray irrigation or when the spray head vehicle 2 walks.

Referring to fig. 2-4, it will be further appreciated that to increase the pressure of the spray and facilitate water injection and weight gain into the serpentine coil 2012, the controller is required to remotely control the opening and closing of the three-way valve 204, and to control the state of the three-way valve 204 in real time, thereby injecting water into the serpentine coil 2012. In actual operation, when water needs to be injected into the serpentine coil 2012, the controller only needs to control the three-way valve 204 to start, so that water in the PE pipe 109 enters the serpentine coil 2012 through the three-way valve 204. As the distance travelled by the spray head truck 2 increases, the required counterweight weight increases, and the control valve 2013 on the serpentine coil 2012 can be opened remotely by the controller to allow water to enter the higher layer of serpentine coil 2012, thereby changing the weight of the counterweight adjustment tank 201 and allowing the spray head truck 2 to walk quickly and stably.

It should be noted that, the serpentine coils 2012 are provided with three layers, and the control valve 2013 is disposed between two adjacent sets of serpentine coils 2012, and the specific location is located at the end of the two adjacent sets of serpentine coils 2012. Meanwhile, to reduce the weight of the nozzle vehicle 2, the box 2011 and the serpentine coil 2012 are made of plastic materials, the box cover 2014 is disposed above the box 2011, the box cover 2014 is rotationally connected with the box 2011, and when the serpentine coil 2012 is leaked or blocked, the damaged part of the serpentine coil 2012 can be maintained or replaced by opening the box cover 2014.

It will be appreciated that the serpentine coil 2012 described above can be replaced with longitudinally disposed and interconnected tanks, water bags, hoses, etc., but in the same manner and location as the serpentine coil 2012 of the present application. Next, the mounting position of the control valve is also the same. In particular use, the operation is also the same as the water injection pattern, volume and frequency of the serpentine coil 2012.

Further, a driving part is further provided on the moving frame 205, and the driving part is used for driving the wheels 203 on the moving frame 205 to rotate. The driving part is provided at the front end of the moving frame 205 to prevent the moving frame 205 from being turned over when the PE pipe 109 is pulled. The driving part is specifically a motor 206, a transmission shaft and a transmission 207, wherein the motor 206 is in transmission connection with the transmission 207, the transmission 207 is in transmission connection with the transmission shaft, when the motor 206 is started, power is transmitted to the transmission 207, the transmission 207 transmits power to the transmission shaft, and the transmission shaft transmits power to the wheels 203. The gearbox 104 is provided with a receiver, and the receiver is used for receiving a speed command transmitted by the controller, so as to change the travelling speed of the spray head vehicle 2.

It should be noted that the spray head vehicle 2 may adopt two-drive or four-drive, wherein the two-drive and four-drive modes are the existing transmission modes, and are not described in detail herein. The two-drive or four-drive spray head vehicle 2 is adopted according to specific working conditions.

Further, one end of the PE pipe 109 is communicated with the water inlet pipe 105 of the water turbine tank 106, a three-way valve 204 is disposed at the end of the PE pipe 109 near the weight adjusting water tank 201, one end of the three-way valve 204 is communicated with the PE pipe 109, the other end of the three-way valve 204 is communicated with the water inlet of the bottommost serpentine coil 2012, and the third end of the three-way valve 204 is communicated with the spray head 208. In actual working, when the spray head vehicle 2 needs to reach a designated working position, the three-way valve 204 is remotely controlled by the controller to open the first state, at this time, water in the PE pipe 109 enters the serpentine coil 2012 for adjusting the weight of the spray head vehicle 2, so that the spray head vehicle 2 is prevented from being unable to walk normally due to insufficient gripping force, and when the spray head vehicle 2 reaches the designated position, the three-way valve 204 is opened to the second state, at this time, the water in the PE pipe 109 enters the spray head 208 for sprinkling irrigation of crops to be sprinkling.

The control valve 2013 and the three-way valve 204 are both solenoid valves.

It should be further noted that, when the three-way valve 204 is in the first state, water in the PE pipe 109 enters the bottom-most serpentine coil 2012 of the tank 2011 through the three-way valve 204 first, when the water in the bottom-most serpentine coil 2012 fills the entire pipeline, if the weight of the counterweight of the spray truck 2 still cannot meet the requirement, the operator controls the controller at this time, remotely controls the control valve 2013 between two adjacent serpentine coils 2012 to open, and further fills water into the first-layer serpentine coil 2012 until the counterweight requirement is met.

Further, a drain pipe is provided at the bottom of the box 2011, and is communicated with each layer of serpentine coil 2012, and a valve is provided on the drain pipe, and is also an electromagnetic valve and is in communication connection with the controller. In actual operation, since the spray head vehicle 2 is slowly moved to the spray irrigation host 1 during operation, when the weight of the balance weight needs to be gradually reduced, the valve on the drain pipe needs to be opened, and the water in the serpentine coil 2012 starts to be slowly drained from the coil at the highest layer, so as to meet different weight of the balance weight required when the spray head vehicle 2 moves to different positions.

It will be appreciated that, to enhance the stability of the sprinkler 1, the sprinkler 1 is prevented from tilting on a soft land or the wheels 203 of the sprinkler 1 are sunk into the land, which results in an immovable condition of the sprinkler 1 when it is required to be pulled and moved, so that the lifting anchor 108 is provided at one end of the stand 101, and the lifting anchor 108 specifically comprises a fixed arm and a telescopic rod, the telescopic rod is slidably connected with the fixed arm, and the fixed arm is rotatably connected with the stand 101. When the sprinkler host 1 reaches a specified working position in actual operation, the fixed arm is firstly rotated downwards to open, the telescopic rod is pulled out simultaneously, the end part of the telescopic rod is fixed to the ground or inserted into the ground surface, and then the fastening knob on the fixed arm is screwed down to prevent the telescopic rod from retracting into the fixed arm. The above-described manner can improve the stability of the sprinkler host 1.

Further, a console 107 is further disposed at one end of the stand 101, and the console 107 is used for controlling the retraction of the PE pipe 109. Specifically, the console 107 controls the flow of water inside the water turbine box 106, thereby controlling the turbine assembly inside the water turbine box 106 to stop rotating. The retraction of the PE pipe 109 may be controlled by controlling the opening and closing of the transfer pump. The specific control mode is based on the actual working requirement.

Further, it should be noted that, a clutch is provided on one side of the gearbox 104, and since the weight of the spray head truck 2 needs to be increased during the process when the spray head truck 2 moves to the designated working position, water in the PE pipe 109 needs to be injected into the serpentine coil 2012, but the water flow in the water inlet pipe 105 will wash the turbine assembly in the water turbine box 106 to rotate, and the PE pipe is in a slowly recovered state. In order to avoid the above situation, it is necessary to add a clutch, and when the head truck 2 is far from the sprinkler head 1, it is necessary to prevent the power of the water turbine box 106 from being transmitted to the reel 103, and to prevent the head truck 2 from traveling automatically.

Further, the frame 101 is also provided with a traction portion 102, the traction portion 102 being provided at a side remote from the lifting anchor 108. The specific structure of the traction part 102 is a pull ring, the pull ring is connected with the frame 101 in a welding mode, and when the sprinkler irrigation host 1 needs to move, only the unhooking of the traction vehicle is required to be connected with the pull ring.

Further, in order to enhance the stability of the sprinkler irrigation host 1, lifting anchors 108 are provided at four corners of the frame 101. The end of the telescoping rod of the lift anchor 108 remote from the fixed arm is a fixed disk, ground spike or foot.
