[0055] The water outlet end of the water supply pipe 6 passes through and is fixed on the support part 1, and the water inlet end of the water supply pipe 6 is connected to the water storage tank / box.

[0056] In the utility model, under the action of the water pump, the water source of the water tank / box enters the irrigation assembly through the water supply pipe 6, and finally sprays to complete the irrigation process. The rotation adjustment part 3 is used to adjust the sliding cylinder 21 to rotate, so as to achieve the purpose of adjusting the irrigation spraying direction, so as to achieve the effect of irrigating plants in different positions; the vertical adjustment part 5 is used to adjust the vertical position of the sliding cylinder 21, and further adjust the position of the water outlet 20a, so as to achieve the effect of controlling the irrigation spraying water output per unit time.

[0057] In the utility model, the water spray port 40c, the water storage chamber 40a and the connecting port 40b are connected in sequence to form a water spray channel, which can change the direction of the water flow in a new way. Preferably, the water spray port 40c is inclined upward to increase the water spray distance; preferably, the inner wall of the top of the water storage chamber 40a is in an arc-shaped guide shape to reduce the pressure of the water flow on the water spray part 4.

[0058] In the present invention, a water outlet hole 20a is provided on the circumference of the sliding cylinder 21. When the water outlet hole 20a is connected with the water spraying port 40c, the water spraying channel is opened to complete the irrigation process. When the water outlet hole 20a and the water spraying port 40c do not overlap at all, the water spraying channel is closed.

[0060] In summary, in the utility model, the irrigation amount per unit time and the water spraying direction of the irrigation component can be controlled to meet different irrigation needs. It is suitable for all irrigation scenarios and has a good irrigation effect.

[0061] The support part 1 includes a top bracket 11, a vertical bracket 12 and a base bracket 13. The top bracket 11 and the base bracket 13 are respectively fixed to the upper and lower ends of the vertical bracket 12. A horizontal bracket 14 for connecting the dynamic adjustment part 3 and the vertical adjustment part 5 is provided in the middle of the vertical bracket 12. The water supply pipe 6 passes through and is fixed on the base bracket 13.

[0062] In the utility model, the support part 1 has a good supporting effect on the irrigation components and the water supply pipe 6, thereby avoiding the shaking of the equipment during irrigation and ensuring the stability of the equipment.

[0063] The base bracket 13 is fixed to the ground, or to a motor vehicle for loading the water tank / box.

[0064] In the utility model, the support part 1 is fixed on the ground to facilitate the fixation of the irrigation assembly and the water supply pipe 6; or the support part 1 is fixed on a motor vehicle to facilitate the overall movement of the equipment and improve the irrigation efficiency.

[0065] The rotation adjustment part 3 includes a motor 31, a rotation shaft 32 and a gear 33; the motor 31 is fixed on the base bracket 13, and the motor 31 is a bidirectional rotation motor; one end of the rotation shaft 32 is connected to the power end of the motor 31, and the other end of the rotation shaft 32 is rotationally connected to the bottom of the horizontal bracket 14; the gear 33 is key-connected to the rotation shaft 32;

[0066] A plurality of racks 23 are arranged in parallel on the peripheral surface of the sliding cylinder 21 in the vertical direction. The plurality of racks 23 are meshed with the gear 33 to form a transmission mechanism.

[0067] It should be noted that the motor 1 31 is a bidirectional rotating motor.

[0068] In the utility model, the rotating shaft 32 can drive the gear 33 to rotate clockwise or counterclockwise, thereby driving the sliding cylinder 21 to rotate; during the rotation of the sliding cylinder 21, the position where the water outlet 20a and the water spray port 40c intersect with each other (moving along the 4 peripheral surfaces of the water spray part) changes to meet the adjustment needs of the water spray direction.

[0069] In the utility model, a plurality of racks 23 are meshed with the gears 33, the transmission process is stable, and when the sliding cylinder 21 (and the racks 23) move in the vertical direction, the racks 23 and the gears 33 can still maintain a meshed state. Therefore, this solution can ensure the stability of the rotation of the sliding cylinder 21 while satisfying the movement of the sliding cylinder 21 in the vertical direction, thereby achieving the effect that the sliding cylinder 21 can rotate and rise and fall.

[0070] The plurality of racks 23 cover 50-70% of the circumference of the sliding cylinder 21;

[0071] In the present invention, the rotation angle of the sliding cylinder 21 is increased to enable the water outlet 20a to move from one side of the water spray port 40c to the other side, thereby achieving maximum adjustment of the water spray angle.

[0072] The cross section of the water spray port 40c is fan-shaped and the central angle is not less than 120 degrees.

[0073] In the present invention, when the water is not completely sprayed, that is, the water outlet 20a and the water outlet 40c are adjusted to intersect each other, and the water outlet 40c is partially blocked; at this time, the water spray direction can be adjusted within the coverage range of the central angle of 120 degrees;

[0074] At the same time, when in the full water spraying state, that is, adjusted to the point where the water outlet 20a and the water spray port 40c do not cross at all, the water spray port 40c is fully opened; at this time, the water spraying coverage range of the water spray port 40c reaches 120 degrees, achieving irrigation conditions with maximum coverage and maximum water spraying volume.

[0075] The vertical adjustment part 5 includes a second motor 51, a threaded transmission rod 52, a guide positioning rod 53, a connecting plate 54 and a clamping assembly 55; the second motor 51 is fixed to the top bracket 11, one end of the threaded transmission rod 52 is connected to the power end of the second motor 51, and the other end of the threaded transmission rod 52 is rotatably connected to the top of the horizontal bracket 14; one end of the connecting plate 54 is fixed to the top of the guide positioning rod 53, and the other end of the connecting plate 54 is threadedly connected to the threaded transmission rod 52; the clamping assembly 55 is fixed to the bottom of the guide positioning rod 53;

[0076] A top cover 22 is disposed on the top of the sliding cylinder 21 , and the clamping assembly 55 is rotatably connected to the top cover 22 .

[0077] In the utility model, when the motor 2 51 drives the threaded transmission rod 52 to rotate, the guide positioning rod 53 forms a limiting mechanism with the top cover 22 through the clamping assembly 55, thereby preventing the guide positioning rod 53 from moving in the horizontal direction; therefore, the connecting plate 54 can move in the vertical direction under the rotation of the threaded transmission rod 52;

[0078] It should be noted that the second motor 51 is a bidirectional rotating motor, which drives the threaded transmission rod 52 to rotate counterclockwise or clockwise to finally complete the raising or lowering action of the connecting plate 54.

[0079] The clamping assembly 55 includes a lower clamping plate 511, a plurality of universal ball wheels 1 552, an upper clamping plate 554 and a plurality of universal ball wheels 2 553;

[0080] The lower clamping plate 511 is fixed to the bottom of the threaded transmission rod 52 and is located inside the sliding cylinder 21. A plurality of universal ball wheels 552 are fixed to the lower clamping plate 511. The rolling balls of the universal ball wheels 552 press the bottom of the top cover 22.

[0081] The outer periphery of the lower part of the guide positioning rod 53 is provided with a thread, and a corresponding threaded hole is opened in the middle of the upper clamping plate 554, and the thread is screwed into the guide positioning rod 53. The upper clamping plate 554 is located above the top cover 22;

[0082] A plurality of universal ball wheels 553 are fixed on the upper clamping plate 554, and the rolling balls of the universal ball wheels 553 press the top of the top cover 22 to form a rotating clamping mechanism.

[0083] In the present invention, there is rolling friction between the plurality of universal ball wheels 1 552, the plurality of universal ball wheels 2 553 and the top cover 22, and the clamping action of the top cover 22 can be completed by adjusting the position of the upper clamping plate 554;

[0084] In summary, this solution can not only clamp the top cover 22 to achieve the purpose of driving the moving part 2 to move in the vertical direction, but also can not affect the rotation of the top cover 22 itself, so that the lifting and rotating actions of the moving part 2 do not interfere with each other.

[0085] The water outlet hole 20a is divided into a gradual hole 20a1 and a uniform width hole 20a2 from top to bottom; the gradual hole 20a1 gradually widens from top to bottom until it has the same width as the uniform width hole 20a2; the uniform width hole 20a2 has the same width from top to bottom.

[0086] The height of the equal-width hole 20a2 is the same as the height of the water spout 40c; the height of the gradual hole 20a1 is greater than the height of the equal-width hole 20a2.

[0087] In the present invention, the gradual hole 20a1 gradually widens from top to bottom, so when the sliding cylinder 21 gradually moves upward, the water outlet generated between the water outlet hole 20a and the water outlet 40c gradually increases, that is, the purpose of increasing the irrigation amount per unit time is achieved; on the contrary, this reduces the irrigation amount per unit time. When the sliding cylinder 21 moves upward until the equal-width hole 20a2 is completely connected with the water outlet 40c, the water outlet 40c is fully opened, the irrigation amount per unit time reaches the maximum, and the effect of maximum irrigation coverage is achieved at the same time.

[0088] In the present invention, the greater the height of the gradual hole 20a1, the more accurate the adjustment of the position of the water outlet hole 20a, that is, the more accurate the control of the water output per unit time, and the better the control effect of the irrigation amount. The height of the gradual hole 20a1 is greater than the height of the equal-width hole 20a2. Preferably, the height of the gradual hole 20a1 is 2-3 times the height of the equal-width hole 20a2, so as to achieve a more accurate control process.

[0089] In the present invention, the height of the equal-width hole 20a2 is the same as the height of the water spray port 40c, so as to achieve the purpose of fully opening the water spray port 40c.

[0090] In summary, the vertical adjustment part 5 achieves the purpose of controlling the amount of irrigation per unit time, so as to adjust the irrigation amount according to demand, avoid water waste, and improve the quality and efficiency of irrigation.

[0091] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
