Description

Technical Field

[0001] This invention relates to the field of mobile sprinkler irrigation technology, and specifically to an auxiliary device for a high ground clearance mobile sprinkler irrigation machine. Background Technology

[0002] Currently, sprinkler irrigation machines mainly include large center-pivot sprinkler irrigation machines, medium-sized reel sprinkler irrigation machines, and small-sized sprinkler units. Large center-pivot sprinkler irrigation machines are mainly used in the United States, while medium-sized reel sprinkler irrigation machines are mainly used in Europe and parts of Northeast and Northwest my country. Medium-sized reel sprinkler irrigation machines have long suffered from a low level of automation. However, with the development of industrial automation and intelligentization in my country, the automation level of reel sprinkler irrigation machines has been continuously improving.

[0003] Mobile sprinkler irrigation machines are suitable for rectangular plots, enabling large-area irrigation with high land utilization, wide irrigation coverage, uniform water distribution, energy savings, and reduced operating costs. Chinese patent CN103931471A discloses a "self-propelled reel sprinkler irrigation machine," which primarily achieves the self-propelled function of a reel sprinkler irrigation machine. However, it uses a traction method for movement, resulting in a complex structure and lack of intelligent control. Furthermore, reel sprinkler irrigation machines suffer from numerous problems such as large size, weight, and high water pressure, significantly reducing the production cost of mobile sprinkler irrigation systems.

[0004] Because high-clearance walking sprinkler irrigation machines carry reels, the moving speed of the PE pipes and the spacing between each layer of PE pipes are greater than the spacing between each row of crops. Furthermore, the irrigated soil is quite muddy, and a large amount of soil is carried along when the PE pipes are retrieved. To address the issues of PE pipe moving speed, straight pipe alignment, and soil removal, an auxiliary device was designed for the high-clearance walking sprinkler irrigation machine. The *Journal of Agricultural Machinery*, in its article "Water Distribution Characteristics and Experiments of Sprinkler and Hose Irrigation Dual-Purpose Units" (Issue 11, 2009), studied the irrigation effect of a reel-type sprinkler irrigation machine using refraction sprinklers and hose irrigation, indicating that the traveling speed of the sprinkler is one of the main factors affecting the uniformity of water distribution. Real-time monitoring of the PE pipe moving speed of the high-clearance walking sprinkler irrigation machine is crucial for coordinating the high-clearance machine's traveling speed with the reel's unloading speed. A search revealed no relevant reports on the issues of straight PE pipe alignment and soil removal. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary device for high-clearance walking sprinkler irrigation machines, which solves the problem of lateral movement of PE pipes from the reel damaging crops. It also has the functions of removing muddy soil, detecting the moving speed of the PE pipe, and reducing the friction of the PE pipe.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] An auxiliary device for a high-clearance walking sprinkler irrigation machine mainly includes a pressure plate, a lower pulley, an encoder, a signal detection system, an octagonal frame, a first support, a second support, a lower pulley shaft, a coupling, and an encoder frame. The octagonal frame includes two connected rods, each rod having a first end and a second end. The first ends of the two rods are respectively connected to both sides of the lower pulley to form the head of the octagonal frame, and the second ends of the two rods are respectively connected to a pressure plate. Each pressure plate has two through holes for connecting to the high-clearance walking sprinkler irrigation machine. The octagonal frame is divided into three equal parts along its length, with the first support and the second support connecting at the division points. Two supports connect the two rods to maintain the stability of the auxiliary device structure. The first ends of the two rods are respectively provided with opposing second holes. The lower pulley shaft passes sequentially through the second hole of one rod, the center hole of the lower pulley, and the second hole of the other rod, connecting the two rods to both sides of the lower pulley. After passing through the rods, the lower pulley shaft connects to the coupling, which is fitted onto the output shaft of the encoder. The encoder is connected to the encoder frame via standard bolts. The encoder frame is welded to the octagonal frame. The signal detection system is connected to the encoder to display the moving speed of the PE tube.

[0008] Furthermore, the head is connected to an upper pulley frame, and an upper pulley is connected to the upper pulley frame, with the upper pulley and the lower pulley facing each other.

[0009] Furthermore, the upper pulley frame is U-shaped, and the two ends of the opening of the U-shaped upper pulley frame are respectively connected to the first ends of the two rods, and the upper pulley is fitted in the middle of the base of the U-shaped upper pulley frame.

[0010] Furthermore, a mud removal device is connected to the upper pulley frame via a mud removal device bracket. The mud removal device is cylindrical and has a circular blade at the through-hole for removing muddy soil.

[0011] Furthermore, the lower pulley, upper pulley, and descaling device are kept in the same horizontal plane. The upper pulley frame and the octagonal frame maintain an 80-degree outward tilt angle to press the PE pipe onto the lower pulley. The descaling device and the upper pulley frame maintain a 90-degree outward tilt angle to allow the PE pipe to pass through the hole of the descaling device and the gap between the lower pulley and the upper pulley before tilting downward.

[0012] Furthermore, the distance between the two rods increases from the first end to the second end.

[0013] The beneficial effects of this invention are as follows: This invention uses a lower pulley, an upper pulley, and a mud-removing device to fix the PE pipe between rows, protecting crop growth and removing mud and soil carried by the PE pipe. Simultaneously, it reduces the friction between the PE pipe and the ground, and an encoder detects the movement speed of the PE pipe. This auxiliary device has a simple structure, is easy to manufacture, and has low cost. It reduces damage to crops, lowers labor intensity, and is of great significance for high-clearance walking sprinkler irrigation machines.

[0021] Please see Figure 1-2An auxiliary device for a high-clearance walking sprinkler irrigation machine mainly includes a pressure plate 1, a lower pulley 3, an upper pulley frame 4, an upper pulley 5, a mud removal device bracket 6, a mud removal device 7, an encoder 8, a signal detection system 9, an eight-shaped frame 10, a first support 11, a second support 12, a lower pulley shaft 13, a coupling 14, and an encoder frame 15. The eight-shaped frame 10 includes two connected rods 2, each rod 2 having a first end and a second end, with the distance between the two rods 2 increasing from the first end to the second end. The first ends of the two rods 2 are respectively connected to both sides of the lower pulley 3 to form the head of the eight-shaped frame 10, and the second ends of the two rods 2 are respectively connected to a pressure plate 1. Each pressure plate 1 has two through first holes for connecting to the high-clearance walking sprinkler irrigation machine, dividing the eight-shaped frame 10 into three equal parts according to its length. The two rods 2 are connected at equal intervals by the first support 11 and the second support 12 to maintain the stability of the auxiliary device structure. The octagonal frame 10 is symmetrical about the central axis. The first ends of the two rods 2 are respectively provided with opposite second holes. The sliding wheel shaft 13 passes through the second hole of one rod 2, the central hole of the sliding wheel 3, and the second hole of the other rod 2 in sequence, connecting the two rods 2 to both sides of the sliding wheel 3. After passing through the rods 2, the sliding wheel shaft 13 is connected to the coupling 14. The coupling 14 is sleeved on the output shaft of the encoder 8. The encoder 8 is connected to the encoder frame 15 by standard bolts. The encoder frame 15 is welded to the octagonal frame 10. The signal detection system 9 is connected to the encoder 8 to display the moving speed of the PE pipe.

[0022] The upper pulley frame 4 is U-shaped, with its two open ends welded to the first ends of the two rods 2. The upper pulley 5 is fitted into the middle of the bottom of the U-shaped upper pulley frame 4 to prevent the upper pulley axle from shifting. The upper pulley 5 and the lower pulley 3 are opposite each other. The space enclosed by the U-shaped upper pulley frame 4, the upper pulley 5, and the lower pulley 3 is used for the passage of PE pipes. The mud removal device 7 is cylindrical with a circular blade at its through-hole for removing muddy soil. The mud removal device bracket 6 is welded to both sides of the mud removal device 7, and the mud removal device bracket 6 is welded to the middle of the upper pulley frame 4.

[0023] The lower pulley 3, upper pulley 5, and mud removal device 7 are kept in the same horizontal plane. The upper pulley frame 4 and the octagonal frame 10 maintain an outer tilt angle of 80 degrees to press the PE pipe onto the lower pulley 3. The mud removal device 7 and the upper pulley frame 4 maintain an outer tilt angle of 90 degrees, so that the PE pipe passes through the hole of the mud removal device 7 and the gap between the lower pulley 3 and the upper pulley 5 and then tilts downward.

[0024] Working process: The PE pipe is pressed through the gap between the lower pulley 3 and the upper pulley 5, and then passes through the center hole of the mud removal device 7. When the reel retracts the PE pipe, the mud removal device 7 cuts off the mud and dirt carried by the PE pipe. The lower pulley 3 slides with the PE pipe, which plays the role of conveying the PE pipe and reducing frictional resistance. The rotating shaft of the encoder 8 rotates with the lower pulley 3, so that the signal detection system 9 can read the sliding speed of the PE pipe.

[0025] The embodiments described above are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Any obvious improvements or substitutions that can be made by those skilled in the art without departing from the essence of the present invention are within the protection scope of the present invention.

[0026] Specific embodiments have been used to illustrate the principles and implementation methods of this invention. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this invention. Therefore, the content of this specification should not be construed as a limitation of this invention.
