Description

Technical Field

[0001] This invention relates to drip irrigation network laying devices, and particularly to an electric multi-functional automatic coil laying device for laying drip irrigation or micro-sprinkler irrigation systems. Background Technology

[0002] In modern agricultural and forestry irrigation systems, drip irrigation offers advantages such as water conservation, reduced fertilizer loss, and promotion of crop growth, and is increasingly widely used. Drip irrigation or micro-sprinkler irrigation systems include a water supply network, which is a crisscrossing network of PVC and PE pipes. At the end of the network, the branch pipes have smaller diameters and are typically made of PE pipe in rolls. To avoid material waste and facilitate transportation, the rolls are usually transported to a designated location before laying, and then laid directly using a pipe-laying device. Due to limitations imposed by landscaping conditions, the optimal laying location for the rolls is often deep within the park, where there are no paved roads suitable for motor vehicles. Therefore, the final stage of material transportation, aside from some use of handcarts, mostly relies on primitive methods like carrying by hand. During laying, the pipe rolls are simply laid flat on the ground, and the pipes are pulled by hand to complete the installation. Despite efforts by those skilled in the art to develop a horizontal turntable-structured pipe-laying device that reduces the labor intensity of pipe dragging, its large size prevents the pipe rolls and the device from being transported simultaneously in a handcart or handled by hand. Both must be carried separately by hand or by handcart, increasing the workload and labor intensity of handling and transporting, and reducing pipe-laying efficiency. Therefore, improvements are needed. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing drip irrigation networks, which require separate transportation of pipe materials and pipe-laying devices during branch pipe laying, resulting in low laying efficiency. This invention provides an electric, multi-functional, automatic pipe-laying device for drip irrigation or micro-sprinkler irrigation systems. By appropriately modifying the axle of a handcart to also function as a pipe-laying device, after transporting PE water pipe rolls to the designated site using this handcart, the rolls and the cart are unloaded, the axle is flipped to a vertical position, and the upper wheels form the pipe-laying device. This eliminates the need for separate transportation of the pipe-laying device, reducing transportation workload, lowering labor intensity, and improving laying efficiency.

[0004] To achieve the aforementioned objectives, the present invention adopts the following technical solution.

[0005] An electric multi-functional automatic coil laying device for drip irrigation or micro-sprinkler irrigation systems includes a handcart capable of transporting roll-type water pipes. The handcart includes an axle and a bucket, with the bucket detachably mounted on the axle. The axle includes a wheel axle and two wheels rotatably mounted on the wheel axle. The two wheels consist of a first wheel and a second wheel. A reel inner core is detachably mounted on the outer side of the first wheel, and multiple support legs are detachably mounted on the outer side of the second wheel.

[0006] The device of the present invention, employing the aforementioned technical solution, allows for the transport of rolled water pipes using a two-wheeled handcart. The inner core of the reel and the support legs are loaded into the cart's cargo box and transported along with the rolled water pipes. Upon arrival at the designated location, the cargo box and its contents are unloaded. The inner core of the reel and the support legs are then mounted on two different wheels. The axle is positioned upright with the support legs on the ground and the inner core of the reel facing upwards. The water pipe is then coiled onto the upper wheel, using the inner core of the reel to prevent slippage. The pipe is then released by pulling the free end, achieving the purpose of water pipe laying. Its ingenious design transforms the handcart into a multi-functional device that combines material transport and coil laying functions, eliminating the need for a dedicated pipe-laying device, reducing transportation workload, lowering labor intensity, and improving pipe-laying efficiency.

[0007] Preferably, the inner core of the reel includes at least two circumferentially distributed V-shaped members, with hooks formed at both ends of the V-shaped members; a hook seat is welded to the spokes of the first wheel, and the hook seat has a hook hole for the hooks to be hooked. This simplifies the structure and creates a structure that is easy to assemble and disassemble, facilitating the movement of the trolley after removal. The hook seat can be replaced with a nut, allowing for direct purchase without machining, improving device manufacturing efficiency and reducing manufacturing costs.

[0008] Preferably, the outrigger includes a foot plate and an outrigger seat. The foot plate is vertically welded to one end of a screw-type fixing rod. The outrigger seat is welded to the second wheel via the rim of the second wheel. The fixing rod and the outrigger seat form a height-adjustable fixed connection. This adjustable height connection between the outrigger seat and the fixing rod facilitates leveling the first wheel on uneven ground, thereby improving the stability of the device. The fixing rod uses a screw structure, and the foot plate can be made of angle steel, allowing for direct procurement of finished screws and angle steel profiles from the market, thus improving manufacturing efficiency and reducing manufacturing costs. Furthermore, the through hole through which the fixing rod passes in the outrigger seat can be a screw hole or a smooth hole. When a screw hole is used, the fixing rod is screwed into the screw hole and then locked in place by a locking nut on top of the outrigger seat. When the fixing rod has a smooth hole, nuts are provided on both the upper and lower sides of the outrigger seat. The lower nut is used to adjust the height, and the upper nut forms a locking mechanism between the outrigger seat and the fixing rod. Furthermore, the outriggers are welded to the wheel rims, which moves the outriggers away from the center of the wheel, increasing the distance between the support points and improving the stability of the device.

[0009] Preferably, the device further includes a DC geared motor that can be fixedly connected to the first wheel. The DC geared motor is connected to the wheel axle via a transmission mechanism, forming a coaxial relative rotational motion relationship. The DC power supply for the DC geared motor is detachably fixedly connected to the first wheel. This allows the motor to drive the first wheel to rotate around the wheel axle, providing assistance in pipe laying, especially useful when laying long pipes and towing is laborious, thus reducing the physical effort required for towing. The geared motor and the DC power supply can be fixed to one side of the wheel respectively via corresponding clamping plates. The clamping plates consist of two crescent-shaped clamps that hold the wheel together, and the two clamps are fixed together with bolts.

[0010] More preferably, the transmission mechanism is composed of a gear transmission mechanism or a worm gear transmission mechanism. This utilizes a mature mechanical transmission structure to achieve power transmission, improving reliability. Both transmission mechanisms are characterized by simple structure and compact layout, requiring no lubrication at low speeds, making them particularly suitable for pipe feeding and receiving devices. In the gear transmission mechanism, the driving gear is coaxially and fixedly connected to the output shaft of the DC geared motor, while the driven gear is detachably and fixedly connected to the axle. In the worm gear transmission mechanism, the worm constitutes the output end of the DC geared motor, and the worm wheel is detachably fixed to the axle. Preferably, both the driven gear and the worm wheel have a two-part combined structure, forming a clamping connection with the axle. This can be achieved by fixing them to the axle with a clamp, or by fixing the two parts together as a rigid body with screws.

[0011] More preferably, the DC geared motor is a 24V square geared motor with a flat gearbox. This saves space, improves structural compactness, reduces weight, and enhances the stability of the device.

[0012] A further preferred embodiment includes a control system electrically connected to the DC geared motor; the control system has a wireless communication module. This allows for remote control using wireless communication technology, facilitating single-person pipe laying and installation operations.

[0013] More preferably, the DC geared motor is a variable frequency speed control motor. This facilitates control of the pipe-laying speed and meets the requirements for varying pipe-laying speeds.

[0014] The beneficial effects of this invention are that by modifying the axle of the handcart, it can also perform pipe-laying functions. Furthermore, by incorporating a DC power supply, a geared motor, and a control system that rotates with the wheels, and by installing a transmission mechanism between the wheels and the axle, the wheels can achieve remote-controlled automatic rotation around the axle, thereby reducing the energy consumption for pipe laying and improving laying efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings, but this does not limit the invention to the scope of the embodiments described.

[0021] See Figure 1 , Figure 2 , Figure 3 and Figure 4 An electric multi-functional automatic coil laying device for drip irrigation or micro-sprinkler irrigation systems includes a handcart capable of transporting roll-type water pipes. The handcart includes an axle and a bucket 1, with the bucket 1 detachably mounted on the axle. The axle includes a wheel axle 3 and two wheels rotatably mounted on the wheel axle 3. The two wheels consist of a first wheel 4 and a second wheel 5. A reel inner core 2 is detachably mounted on the outer side of the first wheel 4, and multiple support legs 6 are detachably mounted on the outer side of the second wheel 5.

[0022] The inner core 2 of the reel includes at least two circumferentially distributed V-shaped members 2a, with hooks formed at both ends of the V-shaped members 2a. A hook seat 4a is welded to the spokes of the first wheel 4, and the hook seat 4a has hook holes for the hooks to be attached. The hook seat 4a is made of a nut, and the inner hole of the nut forms the hook hole. The support leg 6 includes a foot plate 61 and a support leg seat 62. The foot plate 61 is vertically welded to one end of a screw-type fixing rod 63. The support leg seat 62 is welded to the rim of the second wheel 5, and the fixing rod 63 and the support leg seat 62 form a height-adjustable fixed connection. The fixing rod 63 adopts a screw structure, the foot plate 61 is made of angle steel, and the fixing rod 63 is located at the inside corner of the angle steel, with the head of the screw abutting against the horizontal surface of the inside corner of the angle steel. The outrigger seat 62 has a through hole for the fixing rod 63, which is a smooth hole. The fixing rod 63 and the smooth hole form a shaft hole mating structure, and are locked in place by locking nuts 64 at both ends of the outrigger seat 62. The height of the outrigger can be adjusted based on the locking nut 64 at the bottom of the outrigger seat 62. The outrigger seat 62 adopts a tubular structure and is located at the connection between the wheel spoke and the wheel rim, and is welded to both the wheel spoke and the wheel rim.

[0023] Additionally, the system includes a DC geared motor 7 that can be fixedly connected to the first wheel 4. The DC geared motor 7 is connected to the wheel axle 3 via a transmission mechanism, forming a coaxial relative rotational motion relationship. A DC power supply 12 for the DC geared motor 7 is detachably fixedly connected to the first wheel 4. The DC geared motor 7 and the DC power supply 12 are respectively fixed to one side of the wheel via corresponding clamping plates. The clamping plates consist of two crescent-shaped clamps, a first clamping plate 10 and a second clamping plate 11, clamping both sides of the wheel. The first clamping plate 10 and the second clamping plate 11 are fixedly connected together by clamping plate bolts 13 and clamping plate locking nuts 14. The clamping plate bolts 13 are welded to the inner side of the first clamping plate 10, and the DC geared motor 7 and the DC power supply 12 are respectively fixedly connected to the outer side of the corresponding first clamping plate 10. The transmission mechanism is composed of a worm gear transmission mechanism, with the worm 8 forming the output end of the DC geared motor 7, and the worm wheel 9 detachably fixed to the wheel axle 3. (See also...) Figure 5 The worm gear 9 has a two-part structure and is clamped to the axle 3. The two parts are fixed together as a rigid body by screws 91. Specifically, axially extending convex rings are formed in the middle of both sides of the worm gear 9. Connecting lugs extend laterally on the convex rings. The lugs of the two parts are adapted to each other. One lug has a screw hole, and the other lug has a through hole for the screw. The shank of the screw 91 passes through the through hole on one part and engages with the screw hole on the other part, thereby fixing the two parts together.

[0024] The DC geared motor 7 is a 24V square geared motor with a flat gearbox, and the DC geared motor 7 is a frequency converter speed control motor; it also includes a control system electrically connected to the DC geared motor 7; the control system has a wireless communication module.

[0025] In this embodiment, the two-lobed worm gear 9 can also have a connecting lug near the rim of the gear ring away from the center, which is connected by screws (this structure is not shown in the attached drawings) to enhance the connection strength and rigidity between the two lobes and ensure reliable operation.

[0026] In this embodiment, the two-lobed worm gear 9 can also be fixed to the axle 3 by a clamp. In this structure, the two-lobed worm gear 9 can also have a connecting lug near the rim of the gear ring away from the center, and be connected by screws (this structure is not shown in the attached drawings).

[0027] In this embodiment, the worm gear 9 can also adopt an integral structure. When an integral structure is adopted, it is pre-fixed on the axle and a set distance is reserved between it and the truck bed 1.

[0028] In this embodiment, the transmission mechanism is composed of a gear transmission mechanism. The driving gear is coaxially and fixedly connected to the output shaft of the DC geared motor 7, and the driven gear is detachably and fixedly connected to the axle (this structure is not shown in the accompanying drawings). See also Figure 5The driven gear and worm gear 9 have the same two-part combination structure and form a clamping connection with the wheel axle 3. Obviously, the driving gear can also adopt an integral structure that is pre-fixed to the wheel axle 3, as long as attention is paid to leaving enough space between it and the truck bed 1.

[0029] In this embodiment, the through hole through which the fixing rod 63 passes on the outrigger 62 can also be a screw hole. The fixing rod 63 is screwed into the screw hole to achieve height adjustment. Then, it is locked by the locking nut 64 on the top of the outrigger 62 (this structure is not shown in the attached drawings).

[0030] In use, this invention involves loading the water pipe roll, the V-shaped component 2a of the roll core, the support legs 6 (excluding the support leg seat 62), the clamp seat, the DC geared motor 7, the DC power supply 12, and the two-part worm gear or gear into the cart's bucket 1. Upon reaching the designated location, the cart and its contents are unloaded. The V-shaped component 2a of the roll core and the support legs 6 (excluding the support leg seat 62) are then installed on two different wheels. The clamp seat, DC geared motor 7, and DC power supply 12 are then installed on the corresponding wheels, and the two-part worm gear or gear is fixed to the corresponding position on the axle 3. Finally, the axle is erected with the horizontal corner of the angle steel supporting the support legs 6 on the ground and the top of the roll core 2 facing upwards. The water pipe roll is placed on the upper wheel, using the roll core to prevent slippage. Electric pipe laying is achieved by controlling the DC geared motor 7, thus fulfilling the purpose of water pipe laying.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
