DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Please refer to Figs. 1-3 In the embodiments of the utility model, an irrigation device for agriculture comprises an adjustable spray head assembly 1, and the adjustable spray head assembly 1 comprises a first threaded sleeve 101, a first L-shaped rotating pipe 102, a corrugated expansion pipe 103, an L-shaped connecting pipe 104, a second threaded sleeve 105, a second L-shaped rotating pipe 106, and a rotating spray head 107.

[0029] The outer side of the first L-shaped rotating pipe 102 and the L-shaped connecting pipe 104 is further provided with an adjusting assembly 2, which is used to realize the spacing adjustment of the L-shaped connecting pipe 104 and the first L-shaped rotating pipe 102.

[0030] The adjusting assembly 2 comprises a fixed ring block 201, a limiting guide rod 202, a fixed circular block 203 and a moving ring block 204.

[0031] The fixed ring block 201 is fixed to the outer side of one end of the first L-shaped rotating pipe 102 close to the corrugated expansion pipe 103, the limiting guide rod 202 is fixed to the end face of the fixed ring block 201 close to the corrugated expansion pipe 103, the fixed circular block 203 is fixed to one end of the limiting guide rod 202 away from the fixed ring block 201, and the L-shaped connecting pipe 104 and the corrugated expansion pipe 103 are distributed between the fixed ring block 201 and the fixed circular block 203.

[0032] The moving ring block 204 is fixed to the outer side of one end of the L-shaped connecting pipe 104 close to the corrugated expansion pipe 103, and the moving ring block 204 is in sliding connection with the limiting guide rod 202, so as to realize the spacing adjustment of the L-shaped connecting pipe 104 and the first L-shaped rotating pipe 102 by moving the moving ring block 204 along the outer wall of the limiting guide rod 202.

[0033] The limiting guide rod 202 is provided with three limiting guide rods 202, which are distributed in a ring shape with the fixed ring block 201 as the center, and the distribution angle of the three limiting guide rods 202 is two hundred and seventy degrees, the corrugated expansion pipe 103 and the L-shaped connecting pipe 104 are distributed between the three limiting guide rods 202, and the L-shaped connecting pipe 104 extends to the outside of the three limiting guide rods 202 through the distribution gaps of the three limiting guide rods 202.

[0034] The moving ring block 204 is internally provided with horizontal through holes matched with the three limiting guide rods 202, one side of the outer wall of the moving ring block 204 is provided with a threaded hole 205 in communication with one horizontal through hole, and a locking bolt 206 is threadedly connected in the threaded hole 205, the locking bolt 206 is closely attached to the outer wall of one limiting guide rod 202, so as to realize the horizontal position fixation of the moving ring block 204.

[0035] In this embodiment: need to supplement is: rotating head 107 is the common irrigation rotating head in the existing market, its principle is to use the centrifugal action of water flow and the driving action of reaction force to make the rotating head rotate while spraying water, and the rotating head has been widely used in irrigation field, so the rotating structure of the rotating head 107 will not be described here.

[0036] The adjustable spray head assembly 1 is fixed to the irrigation column water pipe during installation, and a horizontal threaded connector is welded at the top of the irrigation column water pipe. The overall structure is similar to a "7" shape structure. By screwing the first threaded sleeve 101 with the threaded connector, the installation and fixation of the adjustable spray head assembly 1 and the irrigation column water pipe are completed.

[0037] During this process, when the first threaded sleeve 101 and the threaded connector are not completely tightened, the first L-shaped rotating pipe 102 can rotate 360 degrees around the first threaded sleeve 101. When the first threaded sleeve 101 and the threaded connector are completely tightened, the first L-shaped rotating pipe 102 is pressed and cannot be in a state. Similarly, when the second threaded sleeve 105 and the L-shaped connecting pipe 104 are in a loosened state (it should be noted that the L-shaped connecting pipe 104 is externally threaded for the threaded connection of the second threaded sleeve 105), the second L-shaped rotating pipe 106 can rotate around the second threaded sleeve 105. When the second threaded sleeve 105 and the L-shaped connecting pipe 104 are tightened, the second L-shaped rotating pipe 106 is fixed. Through the above structure, the horizontal position adjustment of the rotating head 107 relative to the irrigation column water pipe and the height adjustment relative to the top of the irrigation column water pipe can be realized. At the same time, during the adjustment process, the second L-shaped rotating pipe 106 and the rotating head 107 can always remain in an upright state, which will not affect the rotation and spraying operation of the rotating head 107.

[0038] In addition, by loosening the locking bolt 206 to release the compression of the limiting guide rod 202, the moving ring block 204 can move along the track of the limiting guide rod 202, thereby realizing the distance adjustment of the L-shaped connecting pipe 104 and the first L-shaped rotating pipe 102. The corrugated expansion pipe 103 expands and contracts to adapt to the distance change of the L-shaped connecting pipe 104 and the first L-shaped rotating pipe 102. Through this structure, the position adjustment of the rotating head 107 is more flexible, and it can be better adjusted to the required horizontal position and height. After the moving ring block 204 is adjusted to the appropriate position, the locking bolt 206 is tightened.

[0039] Please refer to Figs. 1-3 , a sealing element is arranged between the first L-shaped rotating pipe 102 and the first threaded sleeve 101, and between the second L-shaped rotating pipe 106 and the second threaded sleeve 105.

[0040] In the embodiment, the structure can keep good sealing between the first L-shaped rotating tube 102 and the first threaded sleeve 101 and between the second L-shaped rotating tube 106 and the second threaded sleeve 105.

[0041] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent substitutions or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, and all of them should be covered within the protection scope of the present application.
