Description

Technical Field

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

[0002] The reel sprinkler is a highly efficient agricultural irrigation equipment, which mainly transports water to the field through the reel and water pipe system to achieve uniform irrigation over a large area. The main advantages of this sprinkler include large irrigation area, uniform irrigation, easy operation, and significant water-saving effect, so it has been widely used in modern agriculture.

[0003] However, in actual use, reel sprinklers face some technical difficulties, one of which is that when working in the field, the wheels of the sprinkler are easily covered with mud and weeds. This situation is particularly serious after rain or in wet soil conditions. When a large amount of mud and weeds accumulate on the wheels, the friction of the wheels increases, making it difficult for the sprinkler to move, and it may even get stuck and unable to move forward. Long-term accumulation will also cause increased wheel wear, affecting the service life of the sprinkler.

[0004] In order to solve the problem of wheels covered with dirt and weeds, manual cleaning is currently mostly used. Operators need to stop the sprinkler truck regularly and use tools to manually remove the dirt and weeds on the wheels. This method is not only time-consuming and labor-intensive, but also in high-intensity field operations, frequent shutdowns for cleaning will seriously affect sprinkler efficiency and increase operating costs. In addition, the effect of manual cleaning is not stable enough. Sometimes it is difficult to completely remove the dirt and weeds on the wheels, and the remaining residues may continue to affect the movement of the sprinkler truck.

[0005] In addition to manual cleaning, some technical solutions attempt to reduce the adhesion of dirt and weeds by designing wheel structures with more self-cleaning functions. However, these solutions are often complex in structure, high in manufacturing cost, and have limited effect in practical applications. Some other solutions use high-pressure water flow to wash the wheels, but this method wastes water resources and does not meet the original intention of water-saving irrigation.

[0006] Faced with these problems, how to design a device that can automatically clean the dirt and weeds on the wheels without increasing too much cost has become a technical problem that needs to be solved urgently in the field of agricultural machinery. Utility Model Content

[0007] In view of the above-mentioned technical deficiencies, the purpose of the utility model is to provide a reel-type sprinkler for field irrigation, which can automatically remove dirt and weeds on the wheels during the movement of the sprinkler vehicle, thereby improving the travel efficiency of the sprinkler vehicle and reducing the time and labor intensity of manual cleaning.

When the drum 22 on the reel 2 rotates, the water pipe 21 is rolled up on the drum 22, and the pipeline and the second bracket 17 are pulled by the water pipe 21 to move in the direction of the reel 2, and water is sprayed through the nozzle 14 at the same time, so that the water spraying operation is realized while walking;

[0032] The cleaning device 12 comprises a sleeve 126, an arc-shaped baffle 124 and two cleaning units; a vertical pole 13 is fixedly arranged on the second bracket 17, a running wheel 11 is rotatably mounted on the vertical pole 13, and a sleeve 126 is movably sleeved on the vertical pole 13 of the second bracket 17; an adjusting screw hole is arranged on the sleeve 126, an adjusting bolt 121 is installed in the adjusting screw hole, one end of the adjusting bolt 121 abuts against the second bracket 17, and when the adjusting bolt 121 is loosened, the position of the sleeve 126 on the vertical pole 13 can be adjusted; the arc-shaped baffle 124 is placed above the running wheel 11, and one side is fixedly connected to the sleeve 126; two cleaning units are symmetrically arranged on both sides of the arc-shaped baffle 124; the cleaning unit comprises a scraper 125, a shaft 129 and a spring 128; the arc-shaped baffle 1 A mounting hole 127 for accommodating a scraper 125 is provided on 24; an axle rod 129 is rotatably arranged in the mounting hole 127; the scraper 125 is placed in the mounting hole 127, one end of which is fixedly connected to the axle rod 129, and the other end is arranged toward the walking wheel 11; the upper end of the spring 128 is fixedly connected to the arc baffle 124, and the lower end is fixedly connected to the scraper 125; a scraper 1210 is provided at one end of the scraper 125 close to the walking wheel 11; the sleeve 126 is adjusted downward along the vertical rod 13, and the adjusting bolt 121 is tightened to fix the sleeve 126 on the vertical rod 13. At this time, the spring 128 presses down the scraper 125, so that the scraper 1210 fits the outer ring of the walking wheel 11. As the walking wheel 11 rotates, the scraper 1210 scrapes off the mud and weeds adhering to the walking wheel 11.

[0033] In this embodiment, the cleaning device 12 also includes an oscillation unit; the oscillation unit includes a transmission wheel 122, a driven wheel 1214, a driven rod 1212 and an eccentric block 123; a rectangular hole is provided in the middle of the arc baffle 124, the transmission wheel 122 is rotatably installed in the rectangular hole, and the transmission wheel 122 is in rolling contact with the walking wheel 11; the driven rod 1212 is rotatably installed at the upper end of the arc baffle 124; the driven wheel 1214 is fixed on the driven rod 1212 and is in rolling contact with the transmission wheel 122; the eccentric block 123 is fixed on one side of the driven rod 1212; when performing sprinkler irrigation operations, the sleeve 126 is adjusted downward so that the scraper 1210 fits the outer ring of the walking wheel 11, When the traveling wheel 11 rotates, the transmission wheel 122 is driven to rotate, and then the driven wheel 1214 drives the driven rod 1212 to rotate, so that the eccentric block 123 rotates. When the eccentric block 123 rotates, it will generate an oscillating force on the arc baffle 124, and then drive the scraper 125 to vibrate, and shake off the dirt and weeds on the scraper 125 to achieve self-cleaning. The spring 128 can ensure that the scraper 125 is always in contact with the traveling wheel 11. After the sprinkler irrigation operation is completed, the sleeve 126 is adjusted to the upper side of the vertical pole 13 to make the scraper 1210 and the transmission wheel 122 out of contact with the traveling wheel 11, so as to avoid excessive noise in the non-operating state.

[0038] In this embodiment, the cross-sectional shape of the connecting plate 15 is L-shaped. After the latch 16 is inserted into the insertion hole, a section of the first bracket 23 is restricted inside the connecting plate 15 to achieve the connection between the second bracket 17 and the first bracket 23 .

[0039] When in use, the reel sprinkler is towed to the target operation area by a towing vehicle, the latch 16 is first pulled out to make the sprinkler vehicle 1 stay at the starting position, and the towing vehicle continues to drag the reel vehicle 2 to the end point. During the dragging, the drum 22 will rotate to lay the water pipe 21 between the sprinkler vehicle 1 and the reel vehicle 2. Adjust the sleeve 126 downward and rotate the adjusting bolt 121 to fix the position of the sleeve 126, so that the scraper 1210 and the driving wheel 122 are in contact with the traveling wheel 11, and then perform sprinkler irrigation operations, spray water through the sprinkler head 14, and at the same time, the roller 22 rotates the reel water pipe 21, and the water pipe 21 pulls the sprinkler truck 1 to move in the direction of the reel truck 2. When the traveling wheel 11 rotates, the scraper 1210 and the side cutter 1211 are used to clean the dirt and weeds on the traveling wheel 11, and the dirt and weeds on the scraper 125, the scraper 1210 and the side cutter 1211 are shaken off by the oscillation unit, and the cleaning device 12 is self-cleaned.
