Description

Technical Field

[0001] This invention relates to the field of sprinkler irrigation equipment technology, specifically to a crop sprinkler irrigation device. Background Technology

[0002] Sprinkler irrigation systems are a common type of irrigation equipment. Typical sprinkler systems use a pump to draw water, which is then sprayed through pipes and nozzles for irrigation. However, because water evaporates easily when sprayed into the air, and falling droplets are easily blocked by crop leaves, it is difficult to effectively reach the roots, resulting in poor irrigation quality and failure to meet irrigation requirements. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a crop sprinkler irrigation device that has the advantages of adjustable sprinkler position to achieve various irrigation effects.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a crop sprinkler irrigation device, comprising:

[0010] The water supply tank assembly includes an arc-shaped base mounted on the vehicle frame, with a water supply tank rotatably mounted inside the arc-shaped opening of the arc-shaped base, and the main sprinkler pipe connected to the water supply tank via a connecting water pipe.

[0011] The height adjustment frame assembly includes a horizontal slide groove set on the side wall of the frame, a lower support rod slidably set in the horizontal slide groove, multiple lifting cylinders set on the lower support rod, an upper support rod set at the end of the lifting cylinder away from the lower support rod, and the main sprinkler pipe set on the upper support rod;

[0012] The sprinkler head assembly includes a sprinkler head seat, which is a hollow structure. The sprinkler head seat is connected to the main sprinkler pipe. An intermediate pipe is installed inside the sprinkler head seat. An upper sprinkler pipe and a lower sprinkler pipe are movably installed through the top and bottom surfaces of the sprinkler head seat, respectively.

[0013] Preferably, the water supply tank is a hollow cylindrical structure, and the outer peripheral wall of the water supply tank is in contact with the inner wall of the arc-shaped opening of the arc-shaped base, which facilitates adjusting the position of the water supply tank within the arc-shaped opening of the arc-shaped base according to the needs of sprinkler irrigation.

[0014] Preferably, the horizontal slide groove is provided with a screw and nut assembly for driving the lower support rod to slide. The position of the lower support rod can be adjusted by the screw and nut assembly, thereby adjusting the position of the sprinkler head assembly and adjusting the position of the sprinkler according to different needs.

[0015] Preferably, the length directions of the lower support rod and the upper support rod are both parallel to the horizontal plane. The lifting cylinders are evenly distributed along the length direction of the upper support rod, and the extension and retraction directions of the lifting cylinders are perpendicular to the horizontal plane. The height positions of the upper support rod and the sprinkler head assembly can be adjusted by the lifting cylinders to achieve different sprinkler positions.

[0016] Preferably, the main irrigation pipe has a U-shaped structure, and each irrigation head seat is connected in parallel within the U-shaped opening of the main irrigation pipe. The side wall of the irrigation head seat away from the main irrigation pipe is provided with an irrigation channel, and a plug is movably provided in the irrigation channel to facilitate different irrigation methods through the irrigation head assembly.

[0017] Preferably, two horizontal pipes are provided on the outer peripheral wall of the sprinkler head seat. Two adjacent sprinkler head seats are connected by horizontal pipes. The two sprinkler head seats near the two ends of the U-shaped opening of the main sprinkler pipe are connected to the main sprinkler pipe through horizontal pipes. The top and bottom surfaces of the middle pipe are open. Two horizontal pipes are provided on the outer peripheral wall of the middle pipe, corresponding to horizontal pipes one by one, and horizontal pipes two are connected to horizontal pipes one at the corresponding positions. The end of the upper sprinkler pipe inside the sprinkler head seat is movably connected to the top opening of the middle pipe, and the end of the lower sprinkler pipe inside the sprinkler head seat is movably connected to the bottom opening of the middle pipe. The irrigation water can enter into each sprinkler head seat through the main sprinkler pipe, and then be sprayed out by the upper sprinkler pipe and / or the lower sprinkler pipe to achieve the irrigation effect.

[0018] Preferably, multiple inverted L-shaped locking blocks are provided on both the top and bottom surfaces of the sprinkler head seat. A first set of limiting blocks is spaced apart on the outer peripheral wall of the end of the upper sprinkler pipe located outside the sprinkler head seat.

A second set of limiting blocks is spaced apart on the outer peripheral wall of the end of the lower sprinkler pipe located outside the sprinkler head seat. The second set of limiting blocks is movably disposed within the L-shaped opening of the inverted L-shaped locking block on the bottom surface of the sprinkler head seat. The upper sprinkler pipe can be rotated on the sprinkler head seat, causing the first set of limiting blocks to rotate into the L-shaped opening of the inverted L-shaped locking block on the top surface of the sprinkler head seat. Similarly, the lower sprinkler pipe can be rotated on the sprinkler head seat, causing the second set of limiting blocks to rotate into the L-shaped opening of the inverted L-shaped locking block on the bottom surface of the sprinkler head seat. This allows for irrigation through the upper and lower sprinkler pipes, or for the upper and lower sprinkler pipes to be closed.

[0019] Preferably, the limiting block assembly includes:

[0020] There are two upper limit blocks, and the two upper limit blocks are distributed at equal intervals along the outer peripheral wall of the upper sprinkler pipe.

[0021] There are two upper limit blocks, which are evenly spaced along the outer periphery of the upper irrigation pipe and located near the sprinkler head seat. When the upper limit block is rotated into the L-shaped opening of the inverted L-shaped locking block on the top surface of the sprinkler head seat, the upper irrigation pipe can be closed. When the upper limit block is rotated into the L-shaped opening of the inverted L-shaped locking block on the top surface of the sprinkler head seat, the upper irrigation pipe can be opened, and irrigation can be carried out through the upper irrigation pipe.

[0022] Preferably, the second limiting block assembly includes:

[0023] There are two lower limit blocks, and the two lower limit blocks are distributed at equal intervals along the outer peripheral wall of the lower sprinkler pipe.

[0024] There are two lower limit blocks, which are evenly spaced along the outer periphery of the lower irrigation pipe and located near the sprinkler head seat. When the lower limit block is rotated into the L-shaped opening of the inverted L-shaped locking block on the bottom surface of the sprinkler head seat, the lower irrigation pipe can be closed. When the lower limit block is rotated into the L-shaped opening of the inverted L-shaped locking block on the bottom surface of the sprinkler head seat, the lower irrigation pipe can be opened, and irrigation can be carried out through the lower irrigation pipe.

[0025] Preferably, the distance between the upper limit block one and the upper limit block two is adapted to the distance from the end of the upper irrigation pipe outside the sprinkler head seat to the opening on the top surface of the middle pipe, and the distance between the lower limit block one and the lower limit block two is adapted to the distance from the end of the lower irrigation pipe outside the sprinkler head seat to the opening on the bottom surface of the middle pipe. This allows the upper and lower irrigation pipes to be closed when the upper limit block one and the lower limit block one are rotated into the L-shaped opening of the corresponding inverted L-shaped locking block; and the upper and lower irrigation pipes to be opened when the upper limit block two and the lower limit block two are rotated into the L-shaped opening of the corresponding inverted L-shaped locking block, thereby enabling sprinkler irrigation operations.

[0026] The beneficial effects of this invention are as follows: 1. The position of the lower support rod can be adjusted by the screw and nut assembly, thereby achieving the effect of adjusting the position of the sprinkler head assembly; at the same time, the height of the upper support rod and the sprinkler head assembly can be adjusted by the lifting cylinder, thereby meeting the needs of various sprinkler positions and achieving various sprinkler effects.

[0027] 2. The sprinkler head seat is equipped with an upper sprinkler pipe and a lower sprinkler pipe. At the same time, the side wall of the sprinkler head seat away from the main sprinkler pipe is equipped with a sprinkler channel, which allows for the selection of different sprinkler methods as needed, thus improving the diversity of sprinkler irrigation.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] like Figures 1 to 5As shown, the present invention provides a crop sprinkler irrigation device, including a frame 1; a water supply tank assembly 2 rotatably mounted on the frame 1; a height adjustment frame assembly 3 disposed outside the water supply tank assembly 2; a sprinkler main pipe 4 disposed on the height adjustment frame assembly 3, and the sprinkler main pipe 4 connected to the water supply tank assembly 2 via a connecting water pipe 5; multiple sprinkler head assemblies 6 are provided, and the multiple sprinkler head assemblies 6 are arranged in parallel on the sprinkler main pipe 4, and the sprinkler head assemblies 6 are connected to the sprinkler main pipe 4; the water supply tank assembly 2 includes an arc-shaped base 21 disposed on the frame 1, and a water supply tank 22 is rotatably disposed within the arc-shaped opening of the arc-shaped base 21, and the sprinkler main pipe 4 is connected to the water supply tank assembly 2 via a connecting water pipe. 5 is connected to the water supply tank 22; the height adjustment frame assembly 3 includes a horizontal slide groove 31 set on the side wall of the frame 1, a lower support rod 32 is slidably set in the horizontal slide groove 31, a plurality of lifting cylinders 33 are set on the lower support rod 32, an upper support rod 34 is set at the end of the lifting cylinder 33 away from the lower support rod 32, and the main irrigation pipe 4 is set on the upper support rod 34; the sprinkler head assembly 6 includes a sprinkler head seat 61, the sprinkler head seat 61 is a hollow structure, the sprinkler head seat 61 is connected to the main irrigation pipe 4, a middle pipe 62 is set in the sprinkler head seat 61, and an upper irrigation pipe 63 and a lower irrigation pipe 64 are movably connected through the top and bottom surfaces of the sprinkler head seat 61, respectively.

[0042] Sprinkler water enters each sprinkler head seat 61 from the water supply tank 22 through the connecting water pipe 5 and the sprinkler main pipe 4, and then enters the intermediate pipe 62. It is then sprayed out from the upper sprinkler pipe 63 and the lower sprinkler pipe 64. Since the upper sprinkler pipe 63 and the lower sprinkler pipe 64 are respectively set on the top and bottom surfaces of the sprinkler head seat 61, simultaneous irrigation at different heights can be achieved.

[0043] The position of the lower support rod 32 can also be adjusted by sliding within the horizontal groove 31, thereby allowing the spraying positions of the upper irrigation pipe 63 and the lower irrigation pipe 64 to be adjusted horizontally as needed.

[0044] The lifting cylinder 33 can also be activated to drive the irrigation main pipe 4 and the upper support rod 34 to adjust the height position, so that the spraying position of the upper irrigation pipe 63 and the lower irrigation pipe 64 can be adjusted according to the irrigation needs (at the same time, the water supply tank 22 can rotate in the arc opening of the arc base 21).

[0045] Example 2

[0046] Based on Example 1, such as Figure 1 , Figure 4 As shown, the water supply tank 22 is a hollow cylindrical structure, and the outer peripheral wall of the water supply tank 22 is in contact with the inner wall of the arc-shaped opening of the arc-shaped base 21. When the lifting cylinder 33 is activated to drive the sprinkler main pipe 4 and the upper support rod 34 to adjust the height, the water supply tank 22 can be rotated in the arc-shaped opening of the arc-shaped base 21 to adjust its position, thereby facilitating smooth water flow during sprinkler irrigation.

[0047] Example 3

[0048] Based on Example 1, such as Figure 4 As shown, a screw and nut assembly for driving the lower support rod 32 to slide is provided in the horizontal slide groove 31; the position of the lower support rod 32 can be adjusted by the screw and nut assembly, so as to adjust the position of the sprinkler head assembly 6 horizontally and thus adjust the position of the sprinkler according to different needs.

[0049] Example 4

[0050] Based on Example 1, such as Figures 4 to 5 As shown, the length directions of the lower support rod 32 and the upper support rod 34 are both parallel to the horizontal plane. The lifting cylinders 33 are evenly distributed along the length direction of the upper support rod 34, and the extension and retraction directions of the lifting cylinders 33 are perpendicular to the horizontal plane. The upper support rod 34 and the sprinkler head assembly 6 can be adjusted in the vertical direction by the lifting cylinders 33, so that the spraying positions of the upper sprinkler pipe 63 and the lower sprinkler pipe 64 can be adjusted in the horizontal direction as needed.

[0051] Example 5

[0052] Based on Example 1, such as Figures 1 to 9 As shown, the main irrigation pipe 4 has a U-shaped structure, and each sprinkler head seat 61 is connected in parallel within the U-shaped opening of the main irrigation pipe 4. A sprinkler channel 65 is provided on the side wall of the sprinkler head seat 61 away from the main irrigation pipe 4, and a plug 66 is movably disposed within the sprinkler channel 65. Two horizontal pipes 611 are provided on the outer peripheral wall of the sprinkler head seat 61, and adjacent sprinkler head seats 61 are connected by horizontal pipes 611. The two sprinkler head seats 61 closest to the two ends of the U-shaped opening of the main irrigation pipe 4 are connected by horizontal pipes 611. Pipe 611 is connected to the main sprinkler pipe 4. The top and bottom surfaces of the intermediate pipe 62 are open. Two horizontal pipes 621, corresponding to the horizontal pipe 611, are provided on the outer peripheral wall of the intermediate pipe 62. The horizontal pipes 621 are connected to the corresponding horizontal pipes 611. One end of the upper sprinkler pipe 63, located inside the sprinkler head seat 61, is movably connected to the top opening of the intermediate pipe 62. One end of the lower sprinkler pipe 64, located inside the sprinkler head seat 61, is movably connected to the bottom opening of the intermediate pipe 62.

[0053] The irrigation water can enter each sprinkler head seat 61 through the main sprinkler pipe 4 (the sprinkler head seat 61 and the main sprinkler pipe 4 can be connected by a horizontal pipe 1 611, that is, the irrigation water can enter the intermediate pipe 62 through the main sprinkler pipe 4 via the horizontal pipe 1 611 and the horizontal pipe 2 621, and then be sprayed out from the top and bottom surfaces of the intermediate pipe 62 into the sprinkler head seat 61). The irrigation water entering the sprinkler head seat 61 can be sprayed out from the upper irrigation pipe 63 and / or the lower irrigation pipe 64 to achieve irrigation.

[0054] Since one end of the upper irrigation pipe 63 located inside the irrigation head seat 61 is movably connected to the top opening of the intermediate pipe 62, and one end of the lower irrigation pipe 64 located inside the irrigation head seat 61 is movably connected to the bottom opening of the intermediate pipe 62; when using the upper irrigation pipe 63 and the lower irrigation pipe 64, the upper irrigation pipe 63 and the lower irrigation pipe 64 can be rotated to the outside of the top opening and the bottom opening of the intermediate pipe 62, respectively; when the upper irrigation pipe 63 and the lower irrigation pipe 64 are not needed, the upper irrigation pipe 63 and the lower irrigation pipe 64 can be rotated to the inside of the top opening and the bottom opening of the intermediate pipe 62, respectively.

[0055] Example 6

[0056] Based on Example 1, such as Figures 2 to 9 As shown, multiple inverted L-shaped locking blocks 7 are provided on both the top and bottom surfaces of the sprinkler head seat 61. Limiting block group one 8 is spaced apart on the outer peripheral wall of the end of the upper sprinkler pipe 63 located outside the sprinkler head seat 61. Limiting block group one 8 is movably disposed within the L-shaped opening of the inverted L-shaped locking block 7 on the top surface of the sprinkler head seat 61. Limiting block group two 9 is spaced apart on the outer peripheral wall of the end of the lower sprinkler pipe 64 located outside the sprinkler head seat 61. Limiting block group two 9 is movably disposed within the L-shaped opening of the inverted L-shaped locking block 7 on the bottom surface of the sprinkler head seat 61. Limiting block group one 8 includes two upper limiting blocks 81, which are equidistantly distributed along the outer peripheral wall of the upper sprinkler pipe 63. Two upper limiting blocks 82 are also provided, which are equidistantly distributed along the outer peripheral wall of the upper sprinkler pipe 63. The upper limit block 82 is located near the end of the sprinkler head seat 61; the limit block group 9 includes two lower limit blocks 91, which are distributed at equal intervals along the outer peripheral wall of the lower sprinkler pipe 64; the lower limit blocks 92 are also provided, which are distributed at equal intervals along the outer peripheral wall of the lower sprinkler pipe 64, and are located near the end of the sprinkler head seat 61; the distance between the upper limit block 81 and the upper limit block 82 is adapted to the distance from the end of the upper sprinkler pipe 63 outside the sprinkler head seat 61 to the top opening of the middle pipe 62, and the distance between the lower limit blocks 91 and the lower limit blocks 92 is adapted to the distance from the end of the lower sprinkler pipe 64 outside the sprinkler head seat 61 to the bottom opening of the middle pipe 62.

[0057] When it is necessary to use the upper irrigation pipe 63 and the lower irrigation pipe 64 for irrigation, the upper irrigation pipe 63 can be rotated on the irrigation head seat 61 so that the upper limit block 82 rotates into the L-shaped opening of the inverted L-shaped locking block 7 on the top surface of the irrigation head seat 61, at which time the upper irrigation pipe 63 can be opened; at the same time, the lower irrigation pipe 64 can be rotated on the irrigation head seat 61 so that the lower limit block 92 rotates into the L-shaped opening of the inverted L-shaped locking block 7 on the bottom surface of the irrigation head seat 61, at which time the lower irrigation pipe 64 can be opened, so that irrigation can be carried out through the upper irrigation pipe 63 and the lower irrigation pipe 64.

[0058] When irrigation is not required using the upper irrigation pipe 63 and lower irrigation pipe 64 (irrigation can be carried out through the irrigation channel 65, and the channel plug 66 can be removed from the irrigation channel 65 first), the upper irrigation pipe 63 can be rotated on the irrigation head seat 61, so that the upper limit block 81 rotates into the L-shaped opening of the inverted L-shaped locking block 7 on the top surface of the irrigation head seat 61, and one end of the upper irrigation pipe 63 located inside the irrigation head seat 61 rotates into the top opening of the middle pipe 62. At the same time, the lower irrigation pipe 64 is rotated on the irrigation head seat 61, so that the lower limit block 91 rotates into the L-shaped opening of the inverted L-shaped locking block 7 on the bottom surface of the irrigation head seat 61. The lower irrigation pipe 64 is rotated so that one end inside the irrigation head seat 61 is rotated into the bottom opening of the intermediate pipe 62. At this time, the upper irrigation pipe 63 and the lower irrigation pipe 64 are coaxial and in contact with each other. At the same time, the lower irrigation pipe 64 and the upper irrigation pipe 63 are not in contact with the inner circumferential wall of the intermediate pipe 62. At this time, the irrigation water can enter the irrigation head seat 61 from the irrigation main pipe 4 through the horizontal pipe 1 611, the horizontal pipe 2 621, and the intermediate pipe 62, and then be sprayed out through the irrigation channel 65 to achieve irrigation.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
