Description

Technical Field

[0001] This invention relates to the field of irrigation equipment technology, and in particular to an energy-saving irrigation device. Background Technology

[0002] To facilitate the winding and collection of used water hoses, most irrigation devices on the market are equipped with a mechanism for winding the water hose. To prevent the water hose roll from falling off the winding mechanism during the winding process and to facilitate the peeling and disassembly of the wound water hose roll, most irrigation devices are equipped with a blocking and anti-falling mechanism and an auxiliary peeling and disassembly mechanism. When disassembling the wound water hose roll, it is necessary to operate the blocking and anti-falling mechanism to release its blocking and limiting effect on the water hose roll, and to use the auxiliary peeling and disassembly mechanism to push and disassemble the water hose roll. However, in existing irrigation devices, the operation of the anti-detachment mechanism and the auxiliary peeling and disassembly mechanism must be carried out step by step, which is quite troublesome and inconvenient. This indirectly reduces the disassembly efficiency of the hose roll, resulting in poor performance of the irrigation device. Summary of the Invention

[0003] In view of this, the present invention provides an energy-saving irrigation device to solve the problem that the operation of the blocking and anti-falling mechanism and the auxiliary peeling and disassembly mechanism needs to be performed step by step, which is cumbersome and inconvenient, and will indirectly reduce the disassembly efficiency of the water hose roll.

[0004] The technical solution proposed in this invention is as follows: an energy-saving irrigation device, specifically comprising a winding wheel, a sliding drive assembly, and a sliding actuation mechanism. The winding wheel is integrally formed from a rim, six sets of spokes arranged in a circular pattern, and a central ring. Three sets of clamping rods and three sets of L-shaped retaining rods are welded around the six sets of spokes in an alternating pattern. A T-shaped limiting component is slidably mounted on each L-shaped retaining rod. A bushing is welded to one side of the central ring, a limiting ring is welded to the first end of the bushing, and a rod sleeve is welded to one side of the limiting ring. The sliding drive assembly comprises a slip ring, a handwheel, and multiple sets of L-shaped connecting rods arranged in a circular pattern. The sliding drive mechanism consists of a sliding ring, a sliding ring, and three U-shaped connecting plates arranged around it. The sliding ring slides with the outer circumference of the rod sleeve, and the sliding ring slides with the outer circumference of the bushing in the form of a spring push. The tail end of the U-shaped connecting plate is fixedly connected to a push rod, and the push rod slides through the space between the spacer of the two L-shaped retaining rods arranged in a group. When the sliding ring slides toward the sliding ring, it abuts against the sliding ring.

[0005] Furthermore, the spring that pushes the sliding ring is mounted on the bushing and is compressed and clamped between the sliding ring and the limiting ring.

[0006] Furthermore, the take-up reel is used to take up the hose after use, the T-shaped limiter is used to block and limit the hose roll formed by the take-up reel, and the push rod is used to push the hose roll off the take-up reel and remove it.

[0007] Furthermore, it also includes two symmetrically distributed supports, which are integrally formed from a U-shaped support frame and a horizontal support frame. A centering sleeve is welded to the middle of the interior of one U-shaped support frame, and a rotating column is connected to the other side of the central ring. The rotating column and the centering sleeve are rotated together through each other.

[0008] Furthermore, two L-shaped mounting shafts are welded at intervals on a vertical support rod of one of the U-shaped support frames. The horizontal part of the L-shaped mounting shaft is rotatably fitted with pressure rollers. After use, the water hose to be wound is threaded through the compression space between the two pressure rollers. The beginning end of the water hose is connected to a connector. The beginning end of the water hose is threaded and fitted with the gap between two clamps in a set of clamps. The connector abuts against the two clamps in the set.

[0009] Furthermore, a hexagonal drive shaft is slidably mounted inside the rotating column, bushing, and rod sleeve. A retaining ring is fixedly fitted on the part of the hexagonal drive shaft located inside the bushing. A spring is compressed and fitted on the part of the hexagonal drive shaft located between the retaining ring and the limiting ring. A plum blossom knob is welded to the protruding part at the tail end of the hexagonal drive shaft.

[0010] Furthermore, two horizontal bearing plates are symmetrically welded between the bottom portions of the two U-shaped support frames, and three longitudinal bearing plates are welded between the two horizontal bearing plates. A water pump is fixedly installed on the top of one longitudinal bearing plate, and an electric motor is fixedly installed on the top of the other two longitudinal bearing plates. The first end of the motor shaft is connected to the pump impeller shaft, and the tail end of the motor shaft protrudes and is inserted into the anti-slip cover at the tail of the motor. The protruding part of the first end of the hexagonal drive shaft is inserted and matched with the tail end of the motor shaft.

[0011] Furthermore, a frequency converter is fixedly installed on one of the U-shaped support frames. The frequency converter is electrically connected to the motor and is used to supply power to the motor and adjust and change the speed of the motor.

[0012] Furthermore, a retaining ring is welded to the first end of the sleeve, and a tightening bolt is threaded through the peripheral wall of the retaining ring. The first end of the tightening bolt is pressed and abutted against the hexagonal drive shaft.

[0013] The energy-saving irrigation device provided by this invention has the following beneficial effects: 1. By using a frequency converter, the speed of the motor and water pump can be adjusted, thereby changing the water flow rate. This allows the irrigation device to adjust the irrigation flow rate by increasing or decreasing the speed of the water pump and motor to meet different irrigation needs. This avoids the motor and water pump operating at full speed and power even when the irrigation demand is small, which would result in power and energy loss and unnecessary electricity consumption. This helps to reduce the energy consumption of the irrigation device to a certain extent and improve its energy-saving effect.

[0014] Second, during winding, the two pressure rollers can be driven to rotate by friction through the water belt, which guides the water belt and squeezes out the residual water in the water belt, making the water belt in an empty and flattened state, reducing the thickness of the water belt, which helps to reduce the volume of the water belt after winding, making it easier to store and transfer the water belt roll. Moreover, this design can also eliminate the trouble of manually squeezing out the residual water inside the water belt during the winding operation, which helps to reduce the manual operation steps of the winding operation and reduce the workload of workers.

[0015] Third, when the first end of the hexagonal drive shaft is inserted into the first end of the motor shaft, the winding wheel can be connected to the motor drive, allowing the motor to drive the winding wheel to rotate and wind up the water hose. This allows the winding wheel to be driven by the rotational force of the motor, enabling the winding wheel and the water pump to share a single motor drive. This eliminates the need for an additional drive motor for the winding wheel, helping to reduce the weight and cost of the irrigation device. The design of using a motor to drive the winding wheel for rotation and winding eliminates the hassle of manually winding up the water hose after use, improving the convenience of the winding operation.

[0016] Fourth, under normal use (i.e., pumping irrigation), the hexagonal drive shaft can be separated from the motor shaft, decoupling the motor and the winding wheel. This prevents the winding wheel from being driven by the motor for a long time without performing work, thus avoiding unnecessary energy loss. It also prevents the rotating assembly of the winding wheel (i.e., the rotating column) from being driven by high-speed rotation for a long time, which will cause excessive wear. This helps to indirectly reduce the power consumption of the irrigation device and indirectly extend the service life of the rotating column.

[0017] Fifth, through the power transmission of the sliding ring, in this invention, only a simple operation of driving the sliding ring towards the limiting ring via the handwheel is needed to sequentially push and drive the three T-shaped limiting parts to slide towards the limiting ring simultaneously and drive the three push rods to slide away from the spokes simultaneously, unlocking the hose roll and completing the peeling and disassembly of the hose roll. This eliminates the trouble of performing the above two operations step by step, allowing the two operations to be performed in an orderly and one-time manner, which is more convenient and time-saving, and helps to indirectly improve the disassembly efficiency of the hose roll, giving the irrigation core device better performance.

The push rod 804 is slidably engaged with the space between the two L-shaped retaining rods 407 arranged in a group. The sliding ring 701 and the sliding ring 801 are arranged at intervals.

[0024] Preferably, the spring that pushes the sliding ring 803 is mounted on the bushing 405 and is compressed and clamped between the sliding ring 803 and the limiting ring 4051.

[0025] Preferably, the take-up reel 4 is used to take up the hose 5 after use, the T-shaped limiter 409 is used to block and limit the hose roll formed by the take-up reel 4, so as to prevent the hose roll from falling off the take-up reel 4 during the take-up process, and the push rod 804 is used to push the hose roll off the take-up reel 4 to remove it, so as to assist the worker in removing and unloading the hose roll.

[0026] Preferably, it also includes two symmetrically distributed supports 1. The supports 1 are integrally formed by a U-shaped support frame 101 and a horizontal support frame 102. A centering sleeve 105 is welded to the middle position inside one of the U-shaped support frames 101. A rotating column 404 is connected to the other side of the central ring 403. The rotating column 404 and the centering sleeve 105 are rotated through each other.

[0027] Preferably, two L-shaped mounting shafts 103 are welded at intervals on a vertical support rod of a U-shaped support frame 101. The horizontal part of the L-shaped mounting shaft 103 is rotatably fitted with a pressure roller 104. After use, the water hose 5 to be wound is passed through the compression space between the two pressure rollers 104. The first end of the water hose 5 is connected to a connector 501. The first end of the water hose 5 is threaded and engaged with the gap between two clamps 408 in a set of clamps 408. The connector 501 abuts against the two clamps 408 arranged in a group.

[0028] Preferably, a hexagonal drive shaft 6 is slidably mounted through the rotating column 404, bushing 405, and rod sleeve 406. A retaining ring 602 is fixedly fitted on the part of the hexagonal drive shaft 6 located inside the bushing 405. A spring is compressed and fitted on the part of the hexagonal drive shaft 6 located between the retaining ring 602 and the limiting ring 4051. A plum blossom knob 601 is welded to the protruding part at the tail end of the hexagonal drive shaft 6.

[0029] Preferably, two horizontal support plates 106 are symmetrically welded between the bottom portions of the two U-shaped support frames 101, and three longitudinally placed support plates 107 are welded between the two horizontal support plates 106. Among them, a water pump 3 is fixedly installed at the top of one longitudinally placed support plate 107, and a motor 2 is fixedly installed at the top of the other two longitudinally placed support plates 107. The first end of the motor 2 shaft is connected to the shaft of the water pump 3 impeller, and the tail end of the motor 2 shaft protrudes and extends into the anti-slip cover 201 at the tail of the motor 2. The protruding part of the first end of the hexagonal drive shaft 6 is inserted into the tail end of the motor 2 shaft.

[0030] Preferably, a frequency converter 9 is fixedly installed on a U-shaped support frame 101. The frequency converter 9 is electrically connected to the motor 2 and is used to supply power to the motor 2 and adjust and change the speed of the motor 2.

[0031] Preferably, a retaining ring 4061 is welded to the first end of the sleeve 406, and a tightening bolt 4062 is threaded through the peripheral wall of the retaining ring 4061 and a threaded knob. The first end of the tightening bolt 4062 is pressed and abutted against the hexagonal drive shaft 6.

[0032] The working principle, specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in realizing this technical solution will be described and explained in detail below: The inlet of water pump 3 is connected to the irrigation water source through an external pumping hose, and a water hose 5 is fixedly connected to the outlet of water pump 3. Water pump 3 uses the centrifugal force of its internal impeller to draw water from the irrigation water source and uses the water hose 5 to transport it to the field to irrigate the crops. Water pump 3 is driven by the rotation of electric motor 2. The speed of electric motor 2 and water pump 3 can be adjusted by frequency converter 9, thereby changing the water flow rate. This allows the irrigation device to adjust the irrigation flow rate by increasing or decreasing the speed of water pump 3 and electric motor 2 under different irrigation needs. This avoids the electric motor 2 and water pump 3 from maintaining full speed and full power operation under smaller irrigation needs, which would cause power and energy loss and unnecessary power consumption. This helps to reduce the energy consumption of the irrigation device to a certain extent and improve its energy-saving effect.

[0033] It is worth noting that the selection of the inverter 9 model, its connection and wiring method with the motor 2, its operation and use method, and its control principle for the motor 2 are all existing technologies for technicians engaged in equipment electrification modification and design in this field, so they will not be elaborated here.

[0034] When the hose 5 is wound up, the two clamps 408 arranged in a set can block and limit the joint 501, and transmit the traction force of the winding wheel 4 to the entire hose 5 through the joint 501, ensuring the normal winding performance of the winding wheel 4.

[0035] When the first end of the hexagonal drive shaft 6 is inserted into the first end of the rotating shaft of the motor 2, the winding wheel 4 can be connected to the motor 2, allowing the motor 2 to drive the winding wheel 4 to rotate and wind the water hose 5. This allows the winding wheel 4 to be driven by the rotational force of the motor 2, enabling the winding wheel 4 and the water pump 3 to share the same motor 2 for drive. This eliminates the need for an additional drive motor for the winding wheel 4, helping to reduce the weight and cost of the irrigation device. The design of the winding wheel 4 being driven by the motor 2 for rotation and winding eliminates the need for manual winding of the water hose 5 after use, improving the convenience of the winding operation. The hexagonal drive shaft 6, through its... The spring pushes the hexagonal drive shaft 6 to maintain the plug-in transmission in operation. In normal operation (i.e., pumping irrigation), the hexagonal drive shaft 6 can be disconnected from the shaft of the motor 2, decoupling the motor 2 and the winding wheel 4. This prevents the winding wheel 4 from being driven by the motor 2 for a long time without performing work, thus avoiding unnecessary energy loss. It also prevents the rotating assembly of the winding wheel 4 (i.e., the rotating column 404) from being driven by high-speed rotation for a long time, thus helping to indirectly reduce the power consumption of the irrigation device and indirectly extend the service life of the rotating column 404. The hexagonal drive shaft 6 is held in the disconnected and decoupled transmission state by the tightening bolt 4062.

[0036] During winding, the two pressure rollers 104 are driven to rotate by friction through the water belt 5 between them, which guides the water belt 5 and squeezes out the residual water in the water belt 5, so that the water belt 5 is in an empty and flattened state, reducing the thickness of the water belt 5, which helps to reduce the volume of the water belt 5 after winding, making it easier to store and transfer the water belt roll. Moreover, this design can also eliminate the trouble of manually squeezing out the residual water inside the water belt 5 during the winding operation, which helps to reduce the manual operation steps of the winding operation and reduce the workload of workers.

[0037] After winding is completed, the three T-shaped limiting pieces 409 need to be slid toward the limiting ring 4051 to control the three T-shaped limiting pieces 409 to be pulled away from the side of the hose roll away from the spokes 402 (i.e. the outside of the hose roll), thereby releasing the obstruction and limiting of the hose roll and freeing up unobstructed operating space for the hose roll to be pulled out and disassembled. After the above operation is completed, the three push rods 804 need to be used to push and peel the loosened hose roll off the winding wheel 4 to disassemble the hose roll.

[0038] Three connecting rods 704, slip ring 701, and three T-shaped limiting members 409 are connected to form a modified three-crank slider mechanism. Through this mechanism, the handwheel 703 drives the slip ring 701 to slide towards the limiting ring 4051, which in turn drives the three T-shaped limiting members 409 to slide synchronously towards or away from the limiting ring 4051. This controls the three T-shaped limiting members 409 to be inserted into or withdrawn from the outside of the hose reel, thus limiting and locking the hose reel. Alternatively, when the lock is released, the slip ring 701 is held in contact with the limiting ring 4051 by three tension springs 705. When the slip ring 701 is held in this position, the three T-shaped limiting members 409 can be positioned in the protruding insertion limit position. Through the power transmission of the three U-shaped connecting plates 802, the sliding ring 801 is moved towards the plum blossom knob 601, which can drive the sliding ring 803 and the three push rods 804 to slide in the same direction. Rod 804 detaches the hose roll from the take-up reel 4; when the slip ring 701 is driven to slide toward the limiting ring 4051, it comes into contact with the sliding ring 801, which can push the sliding ring 801 toward the plum blossom knob 601, controlling the three push rods 804 to detach the hose roll. Thus, through the power transmission of the sliding ring 801, in this invention, only the simple operation of driving the slip ring 701 toward the limiting ring 4051 by the handwheel 703 is needed to push the three T-shaped limiting pieces 409 to slide toward the limiting ring 4051 in sequence and drive the three push rods 804 to slide away from the spokes 402 in sequence, unlocking the hose roll and completing the detachment of the hose roll. This saves the trouble of performing the above two operations step by step, so that the two operations can be performed in an orderly and one-time manner, which is more convenient and time-saving, and helps to indirectly improve the detachment efficiency of the hose roll, so that the irrigation core device has better performance.

[0039] The three push rods 804 are kept in contact with the spokes 402 by springs installed on the outer periphery of the bushing 405. The three push rods 804 are in this working state when idle and during winding. The hexagonal drive shaft 6 can be pulled out by the swivel knob 601.

[0040] The following points should be noted in this article: 1. The accompanying drawings of the embodiments of the present invention only involve the structures involved in the embodiments of the present invention; other structures can refer to general designs.

[0041] 2. Where there is no conflict, the embodiments of the present invention and the features thereof can be combined with each other to obtain new embodiments.

[0042] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
