Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rolling irrigation machines, in particular to an automatic pipe-putting rolling irrigation machine. BACKGROUND

[0002] With the promotion of land circulation, scale planting is becoming more and more common, which puts forward new requirements for the efficiency improvement, economic labor saving, resource saving and other aspects of irrigation. However, the existing irrigation methods cannot well meet these new requirements: large water flooding irrigation is water and labor consuming, drip irrigation affects mechanical operation, and imported sprinkler irrigation machines are very high in cost. The limitations of these irrigation methods restrict the further improvement of agricultural modernization and socialized service.

[0003] Therefore, it is necessary to provide an automatic pipe-putting rolling irrigation machine as an effective supplement to the existing irrigation methods under new irrigation demands. SUMMARY

[0004] In view of the limitations of the existing irrigation methods, an automatic pipe-putting rolling irrigation machine is provided, and the technical scheme is as follows: An automatic pipe-putting rolling irrigation machine comprises a power frame, a pipe disc, an irrigation part and a flow guiding and sinking preventing structure, and the power frame, the pipe disc, the irrigation part and the flow guiding and sinking preventing structure are connected by the same rotation axis, and the ground rolled by the axis in normal operation is a rectangular ground, and the area of the rectangular ground is equal to the area of the irrigation area.

[0005] The power frame is composed of a power source, a gearbox and a fixing frame. The power source is an internal combustion engine or an electric motor which provides power; the gearbox increases torque and adjusts speed, and the output shaft of the gearbox is designed in a hollow manner; the fixing frame serves to fix and support, and is divided into rolling wheels, a rolling shaft, a support arm, a tail support and tail wheels. The power source and the gearbox are fixed on the support arm of the fixing frame, the power source drives the gearbox, the power is transmitted to the rolling shaft of the fixing frame after being amplified by the gearbox, the rolling shaft drives the rolling wheels to rotate synchronously, the rolling wheels near the middle of the irrigation machine are provided with locking structures and wheel tension springs, the tail of the fixing frame is matched with the tail wheels to reduce the resistance during movement, and the tail support is arranged above the tail wheels.

[0006] The pipe disc is composed of a disc frame, a winding pipe and a transition assembly. The disc frame serves as the framework of the pipe disc and plays a role of support, fixation and guidance. The disc frame is in the shape of a near-cylinder. The radius of the circular surface of the cylinder is less than the radius of the rolling wheel by one diameter length of the winding pipe. The winding pipe is wound on the curved surface of the cylinder in a single layer during operation. The curved surface is provided with U-shaped guide grooves for fixing the winding pipe. A bearing is arranged at the central axis of the cylinder. The pipe disc can rotate freely around the rolling shaft when the winding pipe is being wound. After the winding pipe is installed, the disc frame is clamped on the rolling wheel to rotate synchronously with the rolling wheel. The winding pipe is a wear-resistant hose provided with standard buckles at both ends for convenient connection and disconnection. The first end of the winding pipe is connected to a water source with pressure. The laying speed of the pipe is consistent with the advancing speed. The laid pipe will neither be too loose to bend nor be too tight to be pulled.

[0007] The irrigation part is composed of an irrigation unit, a shaft spring, a universal joint, an end pipe and an extension rod.

[0008] The irrigation unit is composed of a connecting framework, an irrigation pipe and a walking wheel. The connecting framework is welded at the edges to facilitate uniform water dripping. The irrigation pipe is a hard pipe material with holes and is thinner than the winding pipe. This design is conducive to the disc transportation during disassembly and replacement. The irrigation pipes at both ends of the irrigation part are each provided with a set of shaft springs for pulling at the head and tail of the irrigation machine to reduce local lateral movement during operation and to strengthen the overall performance of the irrigation machine. In addition, the irrigation pipe at the head of the irrigation part is connected to the end of the winding pipe through the transition part. The walking wheel is a circular wheel with a consistent circumference and is equal to the circumference of the fixed frame rolling wheel. The center shape is consistent with the shape of the connecting framework to facilitate the passage of the irrigation pipe and the fixation of the connecting framework.

[0009] The connecting frameworks between the irrigation units are connected through the universal joints to adapt to the terrain and adjust the number of irrigation units according to the irrigation depth.

[0010] The end pipes are located at both ends of the irrigation machine and are designed with holes to avoid obstacles that may occur at both ends of the land and to flexibly adjust the irrigation width and area. The head end pipe is arranged on the tail bracket of the power frame. A transition pipe led out by the transition part of the transition part passes through the hollow output shaft of the gearbox. After the rotating sealing element is connected at the end point of the irrigation machine, it is finally connected to the head end pipe. The tail end pipe is connected to the irrigation pipe at the tail end of the irrigation part and is used in combination with the extension rod. The base of the extension rod is fixed to the connecting framework at the tail end of the irrigation part.

[0011] The flow guide anti-trapping structure is composed of a flow guide frame, a V-shaped stick, a collecting pipe, a supporting body and a flow guide pipe. Each walking wheel is provided with a flow guide anti-trapping structure, the flow guide frame is overlapped with the connecting frame on the two sides of the walking wheel, the overlapping part is provided with V-shaped sticks distributed on the edge line of the connecting frame, and the V-shaped sticks are used for preventing the lateral movement of the flow guide frame; the collecting pipe is a soft pipe used for collecting the water flowing out of the irrigation pipe at the walking wheel, the supporting body collects the water in the collecting pipe and guides the water into the flow guide pipe, and the water finally flows to the rear area of the walking wheel through the holes in the flow guide pipe, so that the ground near the walking wheel is water-free during the operation of the irrigation machine, and the walking wheel is prevented from sinking into the mud.

[0012] The automatic pipe placing and pipe replacing time period is long, and multiple machines can be simultaneously observed through time staggering, compared with manual flooding irrigation, the labor intensity is low, and the irrigation efficiency is obviously improved; the irrigation pipe rolls and moves, compared with drip pipe irrigation, the irrigation pipe does not occupy land, is not easy to block, and can be repeatedly used in different land plots; the water head pressure loss of the irrigation pipe is small, the irrigation area is a rectangle, and compared with the existing sprinkler, the irrigation machine has the advantages of energy saving, uniform irrigation and low cost. In view of the current land moderate scale in China, the irrigation machine is especially suitable for the plain irrigation of low crops such as wheat, peanut and pasture.

[0013] It can be known from the above description that: the rolling shaft of the power frame, the rotating shaft of the pipe disc, the rotating shaft of the irrigation part and the dragging shaft of the flow guide anti-trapping structure are on the same axis; and the ground rolled by the axis during normal operation is a rectangular ground, and the area of the rectangular ground is equal to the area of the irrigation area. The meaning is that, in an ideal state, the geometric center displacement vectors of the power frame, the pipe disc, the irrigation part and the flow guide anti-trapping structure are the same.
