Description

A hose reeling device

technical field

The invention relates to the field of agricultural machinery devices, in particular to a hose reeling device suitable for agricultural infusion pipes.

Background technique

Sprinkler irrigation is an advanced irrigation technology, which has the advantages of saving water, labor, land, increasing production and strong adaptability. It is one of the important measures, so it has broad development prospects. There are many classification methods of sprinkler irrigation systems. For example, according to the characteristics of spraying, there are fixed spray type and row spray type. The fixed spray type is divided into pipeline type and unit type, while the row spray type is divided into central pivot type, translation type and reel type. Among them, the reel sprinkler is the leader in irrigation machinery, it can provide economical and reliable service, and it is the best choice for irrigating field crops.

The reel type sprinkler refers to a sprinkler that is supplied with water by a hose, and the hose is wound with a coil to pull a long-range sprinkler, so that the sprinkler moves along the working route during the sprinkler irrigation process. The reel type sprinkler has many advantages: the sprinkler truck can run and stop automatically during the spraying process, the management is simple, the operation is easy, and the labor is saved. Basically, one person can manage one, and the labor intensity is low. The reel type sprinkler has the advantages of compact structure, low cost and less material consumption. Due to the small amount of field engineering, the water supply can be used with a pressure main pipe or a pumping unit, so the sprinkler has good mobility, strong adaptability, and is not immune to Obstacle restrictions in the plot.

Pipe winding is used on many machines, but when the pipes are wound on the reel, there is often the problem of the pipes rolling over each other. The pipes on the traditional reel are scattered, and the length of the pipe that can be wound by the long reel is reduced. In addition, the pipes are rolling against each other. It will also lead to excessive bending of the pipeline and reduce the life of the pipeline. Due to the limited pipeline length of most equipment, or the impact of pipeline rolling on individual equipment is not large, or some equipment needs to be sorted and arranged during the pipeline recycling process, which wastes labor, so the sorting process in the pipeline recycling process has not been achieved. Great promotion. However, the pipes of the reel type sprinkler irrigation machine are generally long, and the regular winding of the pipeline recovery process will inevitably lead to the water inlet being easily folded and blocked, resulting in the failure of the pipeline to deliver water, resulting in failure. Therefore, the existing reel type sprinkler irrigation machine has a soft It is necessary to make technical improvements in the tube winding device.

Four sets of equidistant adjustment jacks 231 form a rectangular core, and when the reel is rotated, the hose is wound around the side of the rectangular core and between the two baffles.

The device guides the hose through the hose guide mechanism 3. The hose guide mechanism 3 can be a guide ring 30 that moves along the direction of the central axis, or the guide ring 30 can be replaced by a polygonal frame, a V-shaped structure, or a semicircular structure with an upward opening. One of various structures, such as a pulley with a horizontal central axis, the hose guide mechanism 3 can keep the hose always in its defined position and is not easy to fall. For the sake of simplicity, this embodiment still uses the guide ring 30 As an example to illustrate, further, in order to avoid large friction between the hose and the hose guide mechanism 3 during the winding process of the guide hose, which may damage the hose or make the hose unsmooth, the inner ring surface of the guide ring 30 is designed to be coated. Set up anti-wear layer. As shown in FIG. 3 , the lower end of the guide ring 30 is fixed on a sliding block 32 through a support column 31 , and the table top 11 of the moving frame 1 is provided with a limit chute 33 along the direction of the central axis which is adapted to the sliding block 32 , The slider 32 moves back and forth between the limit chute 33, thereby driving the guide ring 30 to move in the direction of the central axis of the reel. The movement of the strut 31 , the slider 32 and the guide ring 30 is realized by the cooperation of the threaded barrel 34 and the screw 35 . Specifically, the threaded barrel 34 is installed on the strut 31 . In this embodiment, the opening of the threaded barrel 34 is fixed on the strut 31 .
