Description

Technical Field

[0001] This invention relates to the field of sprinkler irrigation equipment technology, specifically to a cable-powered self-propelled reel-type sprinkler irrigation unit. Background Technology

[0002] The reel sprinkler is a highly efficient water-saving irrigation equipment with advantages such as strong adaptability to terrain, simple operation, labor saving, good irrigation effect, and long service life. It can adapt to different scales of mechanized water-saving irrigation equipment.

[0003] Currently available reel-type sprinkler systems suffer from several problems, including insufficient field applicability, significant energy waste, low automation, and inability to precisely control irrigation volume. The limited adaptability of reel-type sprinkler systems manifests in two main ways: firstly, poor terrain adaptability, particularly in complex terrains such as hills and mountains, limiting their linear irrigation mode; secondly, tractor traction is unsuitable for the mid- and late-stages of crop growth and can easily compact the soil and damage crops. Energy waste is significant because the tractor's output power far exceeds the power required to move the sprinkler head and PE hose, especially during the initial preparation stage when the water pump is not running and the PE hose is empty, resulting in substantial energy waste from tractor traction. Insufficient spray uniformity and low level of automation are also issues. Traditional water turbine-driven reel-type sprinkler systems exhibit speed differences during speed adjustment and sprinkler head retrieval, leading to uneven irrigation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a cable-powered self-propelled reel-type sprinkler irrigation unit. A conductive slip ring is installed on the PE pipe reel water inlet mechanism, and the cable is built into the PE pipe, enabling the sprinkler truck to be switched from tractor-driven to electric drive, allowing the sprinkler to operate solely on electricity.

[0005] The present invention achieves the above-mentioned technical objectives through the following technical means.

[0006] A cable-powered self-propelled reel-type sprinkler unit includes a PE pipe reel, a sprinkler head carriage, and control components;

[0007] The PE pipe reel includes a main shaft mechanism, a drive mechanism, a support frame, a conductive slip ring, and a cable. The support frame is mounted on a frame and supports the reel mechanism. The reel mechanism includes a main shaft mechanism on which PE pipe is wound. The main shaft of the main shaft mechanism is a hollow shaft. One end of the hollow shaft is connected to a water inlet mechanism, which is connected to an external water source. The other end of the hollow shaft is connected to the water inlet of the PE pipe. The drive mechanism drives the reel mechanism to rotate. A conductive slip ring is installed on the main shaft mechanism. The conductive slip ring includes an inner ring and an outer ring. The outer ring is connected to a fixed end, and the inner ring is connected to the outer ring of the main shaft mechanism. The outer ring is connected to a power supply end, and the inner ring is connected to one end of a cable. The other end of the cable passes through the PE pipe and is connected to the electrical equipment of the spray head vehicle.

[0008] The sprinkler cart is equipped with a spray bar, several Y-shaped water distributors, and a control component. The outlet end of the PE pipe is connected to the inlet of the spray bar. The control component is used to control the movement of the sprinkler cart and the spraying of the spray bar.

[0009] Furthermore, the main shaft mechanism is provided with a first cable through hole, through which the cable enters the inside of the PE pipe, and a sealing layer is provided between the cable and the first cable through hole for waterproofing.

[0010] Furthermore, the spray head vehicle includes a hub motor, a traction device, a Y-shaped water distributor, a parallel four-bar folding spray boom, a chassis frame, a lead screw guide rail, a rear spray boom frame, and a spray gun;

[0011] The traction device is installed at the rear end of the chassis frame for pulling the PE pipe; at least two hub motors are installed at the bottom of the chassis frame for driving the spray head vehicle; a lead screw guide rail is installed on the chassis frame, and the parallel four-bar folding spray bar is installed on the lead screw guide rail, which is extended or retracted along the lead screw guide rail by external force; a rear spray bar frame is provided at the front end of the chassis frame, and a spray gun is installed on the rear spray bar frame; several Y-shaped water distributors are respectively provided on the rear spray bar frame and the parallel four-bar folding spray bar, and the Y-shaped water distributors are connected to the water supply system, and the inlet of the water supply system is connected to the outlet end of the PE pipe.

[0012] Furthermore, the hub motor and control components are powered via a cable embedded in a PE pipe.

[0013] Furthermore, the control components include an electric control valve and a manual main valve. The water supply system is equipped with an electric control valve and a manual main valve. The water supply system inlet is equipped with a connecting pipe, which is connected to one end of a PE pipe. The connecting pipe has a second cable through hole for the cable to pass through.

[0014] Furthermore, the electric control valve is controlled by an intelligent control box, which is equipped with an antenna for remote operation.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The cable-powered self-propelled reel-type sprinkler irrigation unit of the present invention is an improved design of the traditional reel-type sprinkler irrigation machine. A hub motor is added to the bottom of the sprinkler head carriage, realizing the intelligentization and automation of the reel-type sprinkler irrigation machine. It has a simple structure, strong adaptability, improved irrigation uniformity, and saves water and energy.

[0017] 2. The cable-powered self-propelled reel-type sprinkler irrigation unit of the present invention has a conductive slip ring installed on the PE pipe reel water inlet mechanism, and the cable is built into the PE pipe, realizing the conversion of the sprinkler head tractor traction to electric drive, and realizing the sprinkler irrigation machine can be operated by relying solely on electricity.

[0018] 3. The cable-powered self-propelled reel-type sprinkler unit of the present invention has a hub motor installed on the main body of the sprinkler truck, enabling the sprinkler truck to move autonomously without a tractor.

[0019] 4. The cable-powered self-propelled reel-type sprinkler irrigation unit of the present invention has a screw guide rail installed on the main body of the sprinkler head carriage to control the extension and retraction of the parallel four-bar folding spray bar, realizing the automatic extension and retraction of the spray bar. A Y-type water distributor is installed on the spray bar to reduce the inlet pressure of the sprinkler irrigation machine.

[0020] 5. In the cable-powered self-propelled reel-type sprinkler unit of the present invention, the movement of the sprinkler head carriage, the retraction and extension of the spray boom, and the control of the electric valve are all controlled by an intelligent control box, realizing remote unmanned operation.

[0021] 6. In the cable-powered self-propelled reel-type sprinkler unit of the present invention, since the cable cannot be fixed to the outside of the PE pipe and uniformly formed into a PE pipe reel, the present invention passes the cable through the PE pipe, so that the cable and PE pipe can be wound together on the reel mechanism. Although the effective cross-sectional area of ​​the PE pipe is reduced, it does not affect the fluid flow. However, in order to ensure the flow rate, the nominal diameter of the PE pipe can be increased and the pressure of the external water source can be increased. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] Current sprinkler carts have a simple structure and lack their own power. During the initial preparation phase of the sprinkler system, a tractor is needed to tow the cart, at which point the water pump is not running and the PE pipe is empty, resulting in significant energy waste. Current research mainly focuses on designing a separate sprinkler cart towing mechanism to replace the tractor, and on power supply methods, research is primarily focused on the reliability of a single solar power system. Existing research shows that the reliability of a single solar power supply is relatively high on sunny days, but it drops significantly on cloudy or rainy days. Under special operating conditions, photovoltaic power generation alone may not be able to meet the load requirements. In addition, some researchers have studied and designed sprinkler cart towing mechanisms using battery power and hub motor drive, while others have researched methods using photovoltaic panels, batteries, and gasoline generators for complementary power supply in their sprinkler cart towing mechanisms. However, regardless of whether it's a single battery power supply or a complementary power supply, it only changes the power supply method of the traction mechanism. Simply adding a traction mechanism to the sprinkler truck changes the traction method without changing the traditional operating mode of the reel-type sprinkler. In use, the traction mechanism of the sprinkler truck has a single function, and the photovoltaic panels, batteries, and gasoline generators all significantly increase its size and weight. The problem of soil compaction when the machine enters the field still exists. Although this problem is improved compared to tractor traction, and energy consumption is reduced, the improvement also increases the complexity of operation and the later maintenance costs. Researchers are exploring integrating the traction mechanism with the sprinkler truck, considering direct power transmission via cable, freeing it from the constraints of generators and batteries, and reducing the overall weight. The first consideration was to add a cable reel in addition to the PE pipe reel, transmitting power to the sprinkler truck through the synchronous movement of the cable and PE pipe, but this greatly increases the cost and the complexity of the machine structure. Researchers also considered fixing the cable to the outside of the PE pipe with cable ties, but this does not allow for safe winding and retrieval. Let's first introduce the winding and guiding mechanism of the PE pipe, which directly affects the safe winding and retrieval of the PE pipe. The guide screw, also known as the reciprocating screw, is one of the core components of the system. It typically uses an "8" screw system, changing the winding and retrieval direction of the PE pipe by switching between forward and reverse threads. This specific thread form and guiding system guides the PE pipe along a predetermined path for winding and retrieval, preventing misalignment and knotting. However, in existing technologies, both the thread form and the connection between forward and reverse threads are designed based on round pipes. This design guides the PE pipe for winding or retrieval through its thread form, thereby achieving automatic pipe arrangement and tight, uniform winding. However, when the cable is fixed to the outside of the PE pipe, forming a non-circular irregular PE pipe, the irregular shape of the irregular PE pipe leads to uneven winding. Furthermore, the irregularity of the irregular PE pipe increases the gap, making it difficult to achieve a tight winding effect, affecting irrigation efficiency and increasing the risk of wear. During reversal, resistance and instability increase, affecting stability.Stable winding of the PE pipe is crucial for ensuring stable recycling and uniform irrigation. Improper winding can significantly impact the operating efficiency of the sprinkler machine and increase operating and maintenance costs. Therefore, after numerous attempts, this invention incorporates the cable 35 within the PE pipe 11, thus solving the problem of synchronous winding and recycling of the PE pipe 11 and the cable 35.

[0037] like Figure 1 As shown, the cable-powered self-propelled reel-type sprinkler irrigation unit of the present invention includes a PE pipe reel 1, a sprinkler head trolley 2, and a control component 3.

[0038] like Figure 2 As shown, the PE pipe reel 1 includes a main shaft mechanism 17, a motor 16, a support frame 15, a conductive slip ring 12, and a cable 35. The two support frames 15 are respectively mounted on the frame. The main shaft mechanism 17 is supported by bearings on the support frames 15. The main shaft mechanism 17 is a key component of the reel mechanism. The PE pipe 11 is wound on the reel mechanism. The main shaft of the main shaft mechanism 17 is a hollow shaft. One end of the hollow shaft is connected to the water inlet mechanism 14, which is connected to an external water source. The support frame 15 is provided with a water inlet mechanism fixing plate 13 for fixing the water inlet mechanism 14. The other end of the hollow shaft is connected to the inlet end of the PE pipe 11; the motor 16 indirectly drives the main shaft mechanism 17 to rotate via a chain drive mechanism to drive the reel mechanism; a conductive slip ring 12 is installed on the main shaft mechanism 17, the conductive slip ring 12 includes an inner ring 121, a first fixing plate 124 and an outer ring 123, the outer ring 123 is connected to the support frame 15, and the inner ring 121 is drivenly connected to the main shaft mechanism 17, that is, the inner ring 121 can rotate with the main shaft mechanism 17; the first fixing plate 124 is connected to the second fixing plate 13 on the water inlet mechanism fixing plate 13 by bolts 18. 1. Connection: The first fixing plate 124 is connected to the outer ring 123, and the second fixing plate 131 is connected to the first fixing plate 124 via a power supply terminal. That is, the outer ring 123 is connected to the power supply terminal, and the inner ring 121 is connected to one end of the cable 35. The other end of the cable 35 passes through the PE pipe 11 and is connected to the electrical equipment of the spray head carriage 2. The main shaft mechanism 17 has a first cable through-hole 171, through which the cable 35 enters the inside of the PE pipe 11. A sealing layer is provided between the cable 35 and the first cable through-hole 171 for waterproofing. The reel rotation is powered by a motor 13, and the reel winding and unwinding speed is controlled by controlling the motor speed. The spray head carriage 2 is equipped with a spray bar, several Y-shaped water distributors, and a control assembly 3. The outlet end of the PE pipe 11 is connected to the inlet of the spray bar. The control assembly 3 is used to control the movement of the spray head carriage 2 and the spraying of the spray bar.

[0039] like Figure 5As shown, the nozzle vehicle 2 includes a hub motor 21, a traction device 22, a Y-shaped water distributor 23, a parallel four-bar folding spray boom 24, a chassis frame 25, a lead screw guide rail 26, a rear spray boom frame 27, and a spray gun 28;

[0040] The traction device 22 is installed at the rear end of the chassis frame 25 for traction of the PE pipe 11; at least two hub motors 21 are installed at the bottom of the chassis frame 25 for driving the nozzle carriage 2; in this embodiment, the chassis frame 25 has three support legs, with hub motors 21 connected to the support legs, one at the front end and two at the rear end, and the steering of the nozzle carriage 2 is controlled by the speed difference of the rear hub motors; the chassis frame 25 is composed of several welded rectangular tubes, and a lead screw guide rail 26 is installed on the chassis frame 25. The parallel four-bar folding spray bar 24 is installed on the lead screw guide rail 26, and the parallel four-bar folding spray bar 24 is extended or retracted along the lead screw guide rail 26 by a linear travel mechanism, such as... Figure 7 and Figure 8 As shown; the chassis frame 25 has a rear spray bar frame 27 at its front end, on which a spray gun 28 is mounted. Y-shaped water distributors 23 are respectively installed on the rear spray bar frame 27 and the parallel four-bar folding spray bar 24. Several of these Y-shaped water distributors 23 are connected to a water supply system 29. The inlet of the water supply system 29 is connected to the outlet of the PE pipe 11. The Y-shaped water distributors 23 directly deliver water to the plant roots. The hub motor 21 and control component 3 are powered via a cable 35 built into the PE pipe 11.

[0041] The control component 3 includes an electric control valve 31 and a manual main valve 37. The water supply system 29 is equipped with both the electric control valve 31 and the manual main valve 37. The inlet of the water supply system 29 is equipped with a connecting pipe 36, which is connected to one end of a PE pipe 11. The connecting pipe 36 has a second cable through-hole 38 for the cable 35 to pass through. The cable 35, within the PE pipe, passes through the entire PE pipe and is led out through the waterproof cable through-hole of the connecting pipe 36 to the intelligent control box 34. Current flows through the outer ring of the conductive slip ring, the inner ring, the cable 35, and the intelligent control box 34. The intelligent control box 34 then transmits the current to control components such as the hub motor 21, the lead screw guide rail 26, the electric control valve 31, and the electric control valve 32. The intelligent control box 34 is equipped with an antenna 33 for remote control.

[0042] The working principle of the cable-powered self-propelled reel sprinkler irrigation unit of the present invention is as follows:

[0043] After power is supplied, the intelligent control box 4 controls the linear travel mechanism to move the slider of the lead screw guide, thereby unfolding the parallel four-bar folding spray boom 24. The motor 16 controls the reel to release the hose, and the nozzle carriage 2 moves forward. The rear spray boom frame does not spray to ensure that the area where the tires travel remains dry throughout the spraying process. Water flows through the water supply system and is sprayed from the Y-shaped water distributor on the parallel four-bar folding spray boom. After reaching the PE pipe, the water is completely released. The motor 16 reverses to retrieve the PE pipe 11, and the hub motor 21 reverses to return the nozzle carriage 2. The valve switches the water flow through the water supply system and sprays from the Y-shaped water distributor and spray gun on the spray boom frame 27. The intelligent control box 4 can control the automatic operation of the system and can also remotely control and transmit operating status signals via an antenna. The intelligent control box also ensures the coordination of the operating speeds of the reel motor and the hub motor to ensure smooth operation.
