Description

Technical Field

[0001] The invention belongs to the technical field of agricultural irrigation machinery and equipment, and in particular relates to a multi-nozzle sprinkler device with frames capable of being freely combined or separated. Background Art

[0002] Sprinklers have a wide range of applications. Sprinkler irrigation can control the amount of water sprayed and the uniformity of irrigation, avoid surface runoff and deep seepage losses that are easy to occur during surface irrigation, and thus improve water utilization efficiency and save irrigation water. Practices in many parts of my country have proved that sprinkler irrigation can not only increase production, but also improve product quality. For example, sprinkler irrigation of tea not only increases production, but also improves the quality. Sprinkler irrigation of fruit trees can greatly increase the proportion of first- and second-grade fruits. Sprinkler irrigation is both a water-saving, yield-increasing, and efficient irrigation method, and a high-energy consumption irrigation method.

[0003] The existing reel-type sprinkler irrigation machine has a water pipe wound around the reel. When spraying, it is pulled to one end of the field by a tractor. The spray gun sprays while the water sprayer moves backward, spraying a rectangular band until it ends at the end of the field. This machine has high irrigation efficiency, low labor intensity, and water saving, so the popularity of sprinklers has been increasing in recent years. However, since the technology of sprinklers is not very mature, there are many defects in structure and function, and many problems have been encountered during use. When the reel rotates, the rack is often disconnected. Once the rack is disconnected, it is necessary to stop the spray pipe operation and repair the rack, which greatly reduces the efficiency of sprinkler irrigation. In addition, the sprinkler irrigation machine only has the function of watering, and the function is relatively simple.

[0004] The existing high-pressure single-nozzle reel-type sprinkler irrigation machine has a change in the spray angle and range of the nozzle due to the reaction force of the water on the nozzle of the nozzle trolley, which reduces the uniformity of water spraying, is not conducive to the normal winding of the water pipe, and may even cause seedling damage. Summary of the invention

[0005] In view of the defects and problems existing in the existing sprinkler irrigation equipment, the present invention provides a combined and separated multi-nozzle sprinkler irrigation device, which is used to overcome the shortcomings of the above-mentioned technology, ensure the uniformity and high efficiency of water spraying, and realize automatic sprinkler irrigation operation.

[0006] The solution adopted by the present invention to solve its technical problem is: a combined and separated multi-nozzle sprinkler irrigation device, including a vehicle main frame, a reel, a water pipe, a gearbox, a driving mechanism and a water pump, a vehicle auxiliary frame is movably connected to the front side of the vehicle main frame, and two support rods are respectively connected to the rear side of the vehicle auxiliary frame through two universal joints. At the same time, a carrier plate lifting and adjusting mechanism is arranged on the front side of the vehicle auxiliary frame, and the carrier plate lifting and adjusting mechanism includes a lifting carrier plate, and a lifting and adjusting rod is fixedly connected to the lower end of the lifting carrier plate. At the same time, a vertical guide sleeve is fixed on the vehicle auxiliary frame, the lifting and adjusting rod is matched and installed in the guide sleeve, and a locking pin is installed on the side wall of the guide sleeve.

[0007] A swing motor is fixed on the upper side of the lifting carrier plate, and an eccentric turntable is installed on the rotating shaft of the swing motor. An eccentric shaft is arranged on the eccentric turntable, and a push-pull plate is hinged on the eccentric shaft.

[0008] Hinge seats are fixed on the two support rods respectively, and the two hinge seats are hinged to the push-pull plates through pins respectively; a forked pipe is arranged at the end of the output end of the water pipe wound on the reel, and nozzles are installed on the two forked pipes respectively, and the two nozzles are fixed on the ends of the two support rods respectively; the input end of the water pipe on the reel is connected to the water outlet of the water pump.

[0009] The middle part of the two support rods is set as a sleeve connection structure, and the two sections of the sleeve can freely extend and retract along the axial direction; at the same time, a series of adjustment holes with different distances from the eccentric axis are distributed on the push-pull plate, and the pins located in the hinge seats of the two support rods can be matched and installed in each adjustment hole.

[0010] A gearbox is installed on the main frame at one side of the reel, and a driven gear coaxial with the reel is arranged on the side of the reel. The driving gear output by the gearbox is meshed with the driven gear, and the input end of the gearbox is connected to the driving motor or the handwheel.

[0011] The water pump is fixed on an independent mobile frame, and the independent mobile frame can be docked with the main frame of the vehicle.

[0012] Beneficial effects of the present invention:

[0013] The present invention can disassemble and combine the main frame, the auxiliary frame and the independent mobile frame respectively, so that each frame can be moved to different sprinkler irrigation areas according to the actual conditions of water sources and the topography of the irrigation area, so as to achieve the purpose of flexible use.

[0014] The invention provides a multi-nozzle swing driving structure that can swing freely and position on the vehicle auxiliary frame, which can improve the efficiency and uniformity of sprinkler irrigation. In addition, the angle of the multi-nozzle can be fixed to achieve fixed-angle sprinkler irrigation, and the multi-nozzle can be driven by a swing motor to achieve reciprocating swing sprinkler irrigation, which has a very good use effect.

[0015] The multi-sprinkler swing drive structure of the present invention can also realize height adjustment, thereby expanding the sprinkler irrigation range.
