[0024] The right surface of frame body 1 is fixedly connected with the first motor 7 for providing power, the output shaft of first motor 7 rotationally penetrates into the inside of frame body 1 and is fixedly connected with two-way threaded rod 6 by coupling, and first motor 7 is the motor with self-locking function, when in the layout uneven drip irrigation belt uses the device and needs to adjust the position of each drip irrigation head 5 separately, can rotate worm 11 to drive worm wheel 10 to rotate, threaded sleeve 9 is rotated by worm wheel 10 rotation, at this time, two-way threaded rod 6 will not produce rotation under the restriction of first motor 7, so it will drive the sliding block 4 to slide outside two-way threaded rod 6, finally realizes the adjustment of single drip irrigation head 5 position.

[0025] The lower surface of fixed block 3 and sliding block 4 is all fixedly connected with the first connecting pipe 13 for connecting, the lower end of first connecting pipe 13 is fixedly connected with the corrugated hose 14 for connecting, corrugated hose 14 is connected with drip irrigation head 5, the surface of first connecting pipe 13 is fixedly connected with the second connecting pipe 15 for connecting, the front side surface of frame body 1 is fixedly penetrated by middle second connecting pipe 15, by external pipeline connection three second connecting pipes 15 respectively can make drip irrigation head 5 irrigate drip irrigation belt.

[0026] The front surface of the frame body 1 is provided with two first through grooves 12 for sliding, and the two worm gears 11 respectively extend out of the frame body 1 through the two first through grooves 12. When the positions of the two sliding blocks 4 are adjusted, the worm gears 11 will generate corresponding positions in the first through grooves 12. The front surface of the frame body 1 is also provided with two second through grooves 16, and the two second connecting pipes 15 respectively extend out of the frame body 1 through the two second through grooves 16. When the spacing between the drip irrigation heads 5 is adjusted, the two second connecting pipes 15 will generate corresponding displacements in the second through grooves 16.

[0027] The swing assembly comprises a second motor 24 for providing power, which is fixedly connected to the surface of the frame body 1. A transmission rod 17 for transmission is rotatably connected between the two side vertical plates of the frame body 1.

[0031] Working principle:

[0032] The variable spacing drip irrigation device for planting, when used in the layout of the drip irrigation belt using the device, can start the first motor 7 through the external controller, through the rotation of the first motor 7 output shaft can drive the bidirectional threaded rod 6 rotation, through the bidirectional threaded rod 6 rotation and by the self-locking between the worm gear 10 and the worm 11, at this time the threaded sleeve 9 can not produce rotation, therefore the rotation of the bidirectional threaded rod 6 will drive the two sides of the sliding block 4 close to each other or away from each other, ultimately realize the rapid adjustment of the spacing between the three drip irrigation heads 5.

[0033] When the device is used in the layout of the drip irrigation belt and needs to adjust the position of each drip irrigation head 5 separately, the worm 11 can be rotated to drive the worm gear 10 to rotate, and the threaded sleeve 9 is rotated by the rotation of the worm gear 10. At this time, the bidirectional threaded rod 6 will not rotate under the restriction of the first motor 7, so as to drive the separate sliding block 4 to slide outside the bidirectional threaded rod 6, and finally realize the adjustment of the position of the single drip irrigation head 5.

[0034] In addition, when the irrigation is carried out in the way of continuous small water flow, the rotation of the transmission rod 17 can be driven by starting the second motor 24 through the external controller, and the cam 18 is rotated under the cooperation of the synchronous groove 21. When the cam 18 rotates, the T-shaped rod 20 will slide in the T-shaped sliding groove 19, so as to force the T-shaped rod 20 to move reciprocatingly in the transverse direction. When the T-shaped rod 20 is forced to move close to one side of the drip irrigation head 5, the drip irrigation head 5 is pushed to swing, and when the T-shaped rod 20 is forced to move away from the drip irrigation head 5, the drip irrigation head 5 is pulled to swing, so as to realize the reciprocating swing of the drip irrigation head 5, and finally realize the increase of the irrigation range.

[0035] In addition, when the sliding block 4 drives the first connecting pipe 13 to move, the first connecting pipe 13 drives the connecting plate 22 to move, at this time the connecting plate 22 slides outside the transmission rod 17, and drives the cam 18 to slide outside the transmission rod 17, so as to drive the corrugated hose 14 and the drip irrigation head 5 to move synchronously.

[0036] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
