Description

Technical Field

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

[0002] The self-propelled reel sprinkler is a highly efficient irrigation device widely used in the agricultural field. This equipment uses a reel system and a sprinkler system to transport water to the field to achieve uniform irrigation over a large area. Its main advantages include easy operation, large irrigation area, significant water-saving effect and uniform irrigation, so it has been widely used in modern agriculture. However, in actual use, the self-propelled reel sprinkler also faces some technical difficulties, especially the problem that the coil is easy to adhere to mud during the winding process.

[0003] When working in the field, sprinklers need to frequently lay and reel in hoses. Due to the different soil conditions in the fields, hoses are easily stained with a lot of dirt and impurities when dragged on the ground. The dirt attached to the hose will significantly increase its weight and diameter, making it difficult to reel in, and may even jam the hose reel, causing the equipment to stop. This not only affects the continuity and efficiency of sprinkler irrigation operations, but also increases the wear and tear of the equipment and the risk of failure.

[0004] Traditional solutions mainly rely on manual cleaning operations. Operators need to stop the machine regularly to manually clean the coils, using brushes or other tools to scrape off dirt and impurities on the coils. This method not only consumes a lot of time and manpower, but also easily leads to incomplete cleaning, affecting subsequent sprinkler irrigation operations. In addition, frequent shutdowns for manual cleaning also greatly reduce the efficiency of the sprinkler irrigation machine and increase operating costs.

[0005] Some automated or semi-automated cleaning devices have also been tried in the prior art. For example, some sprinkler irrigation equipment is equipped with a high-pressure water jet device to wash away the dirt on the surface of the coil by high-pressure water. However, this method has obvious disadvantages. First, high-pressure water flushing will waste a lot of water resources, which is not in line with the original intention of water-saving irrigation; second, high-pressure water may damage the coil and affect its service life; finally, the maintenance cost of the high-pressure water device is high, which is not conducive to widespread application.

[0006] There are also some technical solutions that try to reduce the possibility of soil adhesion by improving coil materials or surface treatment technology. For example, using coils with smooth surfaces or anti-stick coatings. However, although these improvement measures reduce the adhesion of soil to a certain extent, they cannot completely solve the problem, especially in muddy and weedy fields, where soil adhesion is still a serious problem.

[0027] The utility model will be further described below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 7As shown, a self-propelled reel sprinkler includes a reel vehicle 2 and a sprinkler vehicle 1. The reel vehicle 2 and the sprinkler vehicle 1 are both existing structures. The reel vehicle 2 includes a first bracket 23 and a roller 22 installed on the first bracket 23. The roller 22 is provided with a coil 21. The sprinkler vehicle 1 includes a second bracket 11 and a travel wheel 13 and a nozzle 12 installed on the second bracket 11. The nozzle 12 is connected to the coil 21, and also includes a cleaning device 3. The cleaning device 3 includes:

[0029] The mounting frame 31 includes a base 311 and a ring body 312. One end of the base 311 is fixed to the first bracket 23, and the ring body 312 is fixed to the other end of the base 311. The coil 21 passes through the ring body 312.

[0030] The scraper assembly 32 is provided with a plurality of them, which are distributed in a circular array with the axis of the ring body 312 as the center; the scraper assembly 32 includes a rocker arm 321, a roller 323, a scraper 324 and a connecting rod 325; the rocker arm 321 is hingedly mounted on the ring body 312, and the roller 323 is rotatably mounted on one end of the rocker arm 321 close to the sprinkler vehicle 1 and in rolling contact with the outer wall of the coil 21; the connecting rod 325 is fixed to the other end of the rocker arm 321, and one end is hingedly connected to the scraper 324; the scraper 324 is located between the rocker arm 321 and the coil 21; a bending portion 322 is provided on the rocker arm 321, and the roller 323 is mounted on the bending portion 322, and the bending portion 322 extends in the direction close to the axis of the ring body 312.

[0031] Specifically, when performing sprinkler irrigation, the reel 2 is parked at the end position, the sprinkler 1 is parked at the starting position, and sprinkler irrigation is performed through the sprinkler 1. The reel 2 reels the coil 21, and the sprinkler 1 is pulled toward the reel 2 to achieve self-propelled sprinkler irrigation. The inner diameter of the ring body 312 is larger than the outer diameter of the coil 21, so that when the coil 21 passes through the ring body 312, a gap is left between the coil 21 and the ring body 312. When there is soil on the outside of the coil 21, the diameter of the outside of the coil 21 increases, and the soil pushes the roller 323 away from the axis of the ring body 312. Under the principle of leverage, the scraper 324 moves toward the axis of the ring body 312, and the soil is scraped off by the scraper 324.

[0032] In this embodiment, the scraper assembly 32 also includes an adjusting unit 327; the adjusting unit 327 includes a sleeve 3273, a guide rod 3271 and a spring 3272; the upper end of the sleeve 3273 is hinged to the rocker arm 321, and a guide hole is provided at the lower end; the lower end of the guide rod 3271 is hinged to the scraper 324, and the upper end can be movably inserted in the guide hole; the spring 3272 is placed in the guide hole, the upper end is fixed to the sleeve 3273, and the lower end is fixed to the upper end of the guide rod 3271.

[0033] Specifically, the spring 3272 pulls the guide rod 3271 toward the inside of the guide hole so that the front end of the scraper 324 fits as closely as possible to the outer surface of the coil 21; when the soil layer wrapped around the outside of the coil 21 is too thick, the rocker arm 321 is prevented from rotating at too large an angle, causing the scraper 324 to get stuck on the coil 21 and damaging the outer surface of the coil 21. The spring 3272 can also play a buffering role. At this time, the scraper 324 is pressed tightly against the outer surface of the coil 21, and the spring 3272 is stretched to prevent the front end of the scraper 324 from being inserted into the coil 21.

[0034] In this embodiment, a scraper 3242 is fixedly provided on one end of the scraper 324 away from the adjustment unit 327 ; a vertical cutter 3243 is fixedly provided on the end surface of the scraper 3242 close to the rocker arm 321 ; the length direction of the vertical cutter 3243 is parallel to the axial direction of the ring body 312 .

[0035] Specifically, the scraper 3242 is used to cut hard soil layers; the vertical cutter 3243 is used to split large soil layers, making it easier for the scraper 3242 to scrape the soil off the coil 21.

[0036] In this embodiment, a vertical plate 3241 is fixedly disposed on the scraper 324 ; the vertical plate 3241 is disposed at the junction of the scraper 3242 and the scraper 324 ; and the vertical plate 3241 extends along the width direction of the scraper 324 .

[0037] Specifically, the vertical plate 3241 is used to block the soil scraped off by the scraper 324, so that the soil slides down from both sides of the vertical plate 3241, and protects the hinged parts of the connecting rod 325 and the scraper 324 from being covered by the soil.

[0038] In this embodiment, a mounting groove 326 for accommodating the roller 323 is provided on the bending portion 322 ; the roller 323 is rotatably installed in the mounting groove 326 .

[0039] When in use, the sprinkler is first dragged to the working area by a traction vehicle, the sprinkler 1 is stopped at the starting position, and the reel 2 is continued to be dragged to the end point, and the reel 2 releases the coil 21 to the ground, and the reel 2 stops moving after reaching the target position; after the coil 21 is passed through water, the water is sprayed out through the nozzle 12 to irrigate the crops, and the reel 2 reels the coil 21, and the sprinkler 1 is pulled toward the reel 2 by the coil 21. In the process of reeling the coil 21, when there is mud on the outside of the coil 21, the roller 323 will be pushed away from the axis of the ring body 312, so that the scraper 324 moves toward the direction close to the coil 21, and the mud on the coil 21 is scraped and cleaned.
