Description

Technical Field

[0001] This utility model belongs to the field of sprinkler irrigation technology, and specifically relates to an adjustable wheel track frame structure for a self-propelled sprinkler irrigation machine. Background Technology

[0002] In agricultural machinery, there are many machines whose wheels need to travel along the gaps between adjacent crops, such as sprinkler irrigation machines. However, the spacing between different crops is different, so the applicability of sprinkler irrigation machines is questionable. In current sprinkler irrigation machines, the wheel spacing is often not adjustable, making it difficult for the same sprinkler irrigation machine to adapt to the requirements of multiple spacing operations or the requirements of different crops. There are a few existing technologies with adjustable wheel spacing, such as patent CN204451843U, which describes a sprinkler machine operating mechanism. However, its adjustment structure is too simple, its stability may not be sufficient, and it cannot be applied to self-propelled mechanical equipment (i.e., it cannot provide power input to the walking wheels), thus it has certain limitations.

[0023] Specifically, the frame 1 is connected to the movable limiting groove 47 at the corresponding position. The movable limiting groove 47 is provided with a plurality of third connecting holes 48 along its length direction. The upper end of the auxiliary support rod 46 is provided with a fourth connecting hole 49 that cooperates with the plurality of third connecting holes 48 for position locking. That is, when adjusting, the fourth connecting hole 49 is aligned with the corresponding third connecting hole 48 and the position is locked by bolts or pins.

[0024] In some embodiments, auxiliary walking wheel frames 71 are slidably connected to the front two sides of the frame 1 and their positions are locked to adjust the distance between the two auxiliary walking wheel frames 71 to accommodate the adjustment of the walking wheels 2. The auxiliary walking wheel frames 71 are provided with auxiliary walking wheels 72.

[0025] Specifically, the auxiliary walking wheel frame 71 includes a transverse sliding rod 73, which is slidably connected to the frame 1. The frame 1 is provided with a second sliding guide sleeve 13 that cooperates with the transverse sliding rod 73. The transverse sliding rod 73 is provided with a plurality of fifth connecting holes 74 along its sliding direction. The second sliding guide sleeve 13 is provided with a sixth connecting hole 14 at a corresponding position that cooperates with the plurality of fifth connecting holes 74, thereby locking the position. That is, when adjusting, the fifth connecting hole 74 is aligned with the corresponding sixth connecting hole 14 and the position is locked by bolts or pins.
