Description

Technical Field

[0001] The utility model relates to the technical field of sprinkler irrigation machines, in particular to a mobile winch-type sprinkler irrigation machine. Background Art

[0002] In modern agricultural production, irrigation is crucial for ensuring the healthy growth of crops. Capstan-type sprinklers are widely used due to their high efficiency, large coverage area, and ease of operation. However, existing capstan-type sprinklers typically require external equipment for traction during operation. This can be difficult when working on poor road conditions, such as muddy, uneven terrain, or numerous obstacles. This situation not only reduces movement efficiency but also easily causes equipment damage and safety hazards, increasing operational complexity and labor intensity.

[0003] Existing winch-type sprinklers have relatively simple mobility methods, relying primarily on manual pushing and pulling or external traction equipment. This method is acceptable on relatively flat ground, but on rugged or slippery farmland, operation becomes significantly more difficult, time-consuming, and labor-intensive. Furthermore, some existing mobility devices have design flaws that prevent them from effectively adapting to complex terrain. For example, existing sprinklers often utilize a simple wheel-axle structure, lacking flexibility and adaptability. This makes the equipment prone to tipping over or becoming stuck in mud during movement, increasing operational risks.

[0004] Based on this, there is an urgent need for an improved winch-type sprinkler that can move stably and efficiently under complex terrain conditions and reduce dependence on external equipment, thereby improving the efficiency and safety of agricultural irrigation. Utility Model Content

[0005] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a mobile winch-type sprinkler machine that realizes the function of autonomous movement and improves operating efficiency and flexibility.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A mobile winch-type sprinkler includes a chassis, a support frame, a reel, and a sprinkler trolley. The support frame is fixed to the chassis, the reel is rotatably mounted on the support frame, the sprinkler trolley is connected to one end of the reel, and further includes a traveling unit. The traveling unit includes:

[0008] a motor, fixed to the chassis and electrically connected to a power source;

[0009] There are two walking assemblies, which are symmetrically arranged on the chassis; the walking assemblies include walking wheels, a rotating shaft, and a first bevel gear; the rotating shaft is rotatably mounted on the chassis; the walking wheel is mounted on one end of the rotating shaft, and the first bevel gear is mounted on the other end of the rotating shaft;

[0010] The transmission assembly includes a transmission shaft and a second bevel gear; the transmission shaft is placed between the first bevel gears of the two traveling assemblies, and the axis of the transmission shaft is perpendicular to the axis of the rotating shaft; the second bevel gear is installed on the transmission shaft and meshes with the first bevel gear for transmission;

[0011] The rotating cylinder has a cavity inside; a mounting hole for accommodating a rotating shaft is provided on the rotating cylinder, and the rotating shaft is rotatably arranged in the mounting hole; the first bevel gear, the second bevel gear, and the transmission shaft are all placed in the cavity; the transmission shaft is fixedly mounted on the rotating cylinder;

[0012] The first pulley is sleeved and fixed on the outside of the rotating drum and is connected to the motor through a belt transmission.

[0013] Preferably, there are two second bevel gears, which are symmetrically mounted at both ends of the transmission shaft.

[0014] Preferably, a bearing is provided in the mounting hole, and the rotating shaft is rotatably mounted in the mounting hole through the bearing.

[0015] Preferably, it further includes a second pulley; the second pulley is mounted on the output shaft of the motor and is connected to the second pulley via a belt drive.

[0016] Preferably, it also includes a bearing seat; the bearing seat is fixed on the chassis; the rotating shaft is rotatably mounted on the chassis through the bearing seat.

[0017] Preferably, a protective cover is further included; the protective cover is fixed on the chassis and wraps the transmission assembly, the rotating drum, the first pulley and the motor.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] By incorporating a travel unit, this utility model improves the sprinkler's mobility under various ground conditions, eliminating reliance on external traction equipment and simplifying operation. When the motor is started, it drives the rotating drum, which in turn rotates the drive shaft. This, in turn, drives the second bevel gear, via the first bevel gear, to rotate about the axis of the rotating shaft, thereby rotating the travel wheels. When the sprinkler needs to turn, a speed difference occurs between the two travel wheels. The meshing of the first and second bevel gears allows the two rotating shafts to rotate at different speeds, enabling quick turns.

[0020] Furthermore, the symmetrical arrangement of the two travel wheels in the travel assembly effectively distributes the machine's weight, reduces ground pressure, and improves stability on soft surfaces. The transmission assembly, through the coordinated integration of the rotating drum, drive shaft, and bevel gears, achieves efficient power transmission, enabling smooth operation even in complex terrain. Both the rotating drum and transmission assembly are housed within a protective cover, effectively preventing the ingress of dirt and debris, extending the equipment's service life and reducing maintenance costs.
