DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] Please refer to Figure 1-Figure 6 As shown, the present invention provides an agricultural omnidirectional irrigation device, comprising a water inlet pipe 1 and a rotating pipe 2, wherein the rotating pipe 2 is rotatably connected to the periphery of the water inlet pipe 1, and a linkage mechanism for driving the rotating pipe 2 to rotate is arranged on the inner wall of the rotating pipe 2, and the linkage mechanism drives the rotating pipe 2 to rotate along with the flow of water; The outer periphery of the rotating tube 2 is connected to a reciprocating threaded rotating tube 23 which rotates with the rotating tube 2 and rotates automatically. The outer periphery of the reciprocating threaded rotating tube 23 is provided with a telescopic sleeve 4 which moves left and right. A support mechanism is provided at one end of the telescopic sleeve 4, on which a first arc-edge gear 5 is rotatably provided, a second arc-edge gear 7 which is turned up and down along the first arc-edge gear 5 is provided on one side of the first arc-edge gear 5, and a power mechanism which drives the second arc-edge gear 7 to turn over is provided between the second arc-edge gear 7 and the first arc-edge gear 5; The inner wall of the second arc-edge gear 7 is provided with an irrigation mechanism for spraying water toward the farmland; The irrigation mechanism, the power mechanism, the support mechanism and the telescopic sleeve 4 are arranged in a communicating state.

[0019] In the present case, there may be multiple groups or only one group of rotating tubes 2. The attached drawings of the present invention only show one group, wherein the water inlet pipe is laid in the farmland to be irrigated. The rotating tube 2 is a branch pipe arranged on the water inlet pipe 1. During the irrigation process, the water entering the water inlet pipe 1 will flow into the branch pipe, that is, the rotating tube 2. At this time, the rotating tube 2 can be driven to rotate under the action of the linkage mechanism, and rotate in all directions during the irrigation process. The number of rotating tubes 2 is set according to the size of the farmland. Only one group of rotating tubes 2 can be used for small farmland, and multiple groups need to be set for larger farmland, which can be selected according to the size of the irrigated farmland.

[0020] The first arc-edge gear 5 can be supported by the action of the supporting mechanism, and the supporting mechanism is arranged at one end of the telescopic sleeve 4, so that the supporting mechanism can move with the left and right sliding of the telescopic sleeve 4, thereby changing the distance between the supporting mechanism and the rotating tube 2, wherein the irrigation mechanism, the power mechanism, the supporting mechanism and the telescopic sleeve 4 are arranged in a communicating state, the telescopic sleeve 4 is communicated with the reciprocating threaded rotating tube 23, and the reciprocating threaded rotating tube 23 is communicated with the rotating tube 2, so that the water in the water inlet pipe 1 enters the rotating tube 2 and can enter the irrigation mechanism through the reciprocating threaded rotating tube 23, the telescopic sleeve 4, the supporting mechanism and the power mechanism, and finally be discharged from the irrigation mechanism to the farmland for irrigation.

[0021] Among them, the irrigation mechanism is fixedly arranged in the second arc gear 7. Under the action of the power mechanism, the second arc gear 7 can be flipped up and down along the outer periphery of the first arc gear 5, thereby changing the state of the second arc gear 7 to facilitate changing the irrigation range. The reciprocating threaded rotating tube 23 is arranged on the rotating tube 2 and can rotate with the rotation of the rotating tube 2, so that the reciprocating threaded rotating tube 23 can achieve 360° rotation without dead angles, realizing all-round irrigation of the irrigation mechanism and a large irrigation range.

[0022] Supplementary explanation: The telescopic sleeve 4 is threadedly connected to the outer periphery of the reciprocating threaded rotating tube 23. Figure 1 It can be seen that a component for limiting the telescopic sleeve 4 is provided at the top of the rotating tube 2, so that the telescopic sleeve 4 slides left and right on the periphery of the reciprocating threaded rotating tube 23. This movement mode is similar to using a reciprocating threaded rod to drive the parts to move back and forth, which is a commonly used reciprocating movement means in the prior art. Therefore, the reciprocating thread is not drawn on the periphery of the reciprocating threaded rotating tube 23 in the attached drawings. The telescopic sleeve 4 is arranged on the periphery of the reciprocating threaded rotating tube 23 to realize the left and right sliding of the telescopic sleeve 4 to change the range of irrigation.

[0023] Among them, the left and right movement of the telescopic sleeve 4 can change the position of the end of the telescopic sleeve 4, change the coverage range during the irrigation process, irrigate a wider range, improve the irrigation range, and cooperate with the rotation of the rotating tube 2 to achieve all-round irrigation.

[0024] Through the left and right movement setting of the telescopic sleeve 4 and the up and down flipping setting of the second arc gear 7, the movement of the telescopic sleeve 4 can change the distance between the second arc gear 7 and the boundary of the farmland, and the flipping of the second arc gear 7 can change the direction of the irrigation water spray, so that the irrigation water can be sprayed to the boundary of the farmland, and then cooperate with the rotation of the rotating tube 2 to achieve 360° all-round irrigation, which can effectively change the scope of irrigation, carry out all-round irrigation, and the irrigation range is wider, thereby improving irrigation efficiency.

[0025] like Figure 3 and Figure 4 As shown, the linkage mechanism includes an impeller 21 and a mounting plate 211. The impeller 21 is sleeved on the inner wall of the rotating tube 2. The mounting plate 211 is fixedly arranged on the top surface of the impeller 21. The mounting plate 211 is arranged in a cross-shaped structure, and the end of the mounting plate 211 is fixedly connected to the inner wall of the rotating tube 2.

[0026] By setting the impeller 21, the structure of the impeller 21 is as follows Figure 4As shown, the impeller 21 is a product of the prior art, and its structure is mature. When water flows through the impeller 21, it can drive the impeller 21 to rotate. This method belongs to the prior art, and the process of how the impeller 21 rotates is not described. Among them, the impeller 21 is driven by the water flow to rotate, the impeller 21 drives the mounting plate 211 to rotate, and the mounting plate 211 drives the rotating tube 2 to rotate, so that the rotating tube 2 is in a rotating state, and all-round irrigation can be performed during irrigation.

[0027] Supplementary explanation: In order to avoid the problem of insufficient flow or excessive flow during irrigation due to the impeller 21 rotating too fast or too slow, it is necessary to design the impeller 21 and the model of the rotating tube 2 used for irrigation according to the irrigation flow. Since the water flow rate (V) flowing through the impeller 21 = K (correction coefficient) × impeller rotation speed (v) × impeller radius (r), and the water flow rate (Q) flowing through the rotating tube 2 = rotating tube cross-sectional area (M) × water flow rate (V), the water flow rate flowing through the impeller 21 can be calculated by the water flow rate flowing through the rotating tube 2 and the cross-sectional area of ​​the rotating tube 2, and then the radius of the impeller 21 can be calculated according to the required rotation speed of the impeller 21, and then different models of impellers 21 and rotating tubes 2 can be installed.

[0028] In order to enable the impeller 21 to operate normally, the diameter of the impeller 21 is generally designed to be two-thirds of the diameter of the rotating tube 2. Therefore, according to the above calculation formula for the water flow rate, it can be obtained that:

[0029] Among them, Q is the water flow rate flowing through the rotating tube, K is the correction coefficient, which is a coefficient related to the material and structure of the impeller and the rotating tube itself, and can be known after the impeller and the rotating tube leave the factory, r is the radius of the impeller, and v is the impeller rotation speed, that is, the rotation speed of the pipeline rotating tube 2 used for irrigation.

[0030] Through the above design formula, the relationship between the water flow rate flowing through the rotating tube 2, the rotation speed of the rotating tube 2 (the rotation speed of the impeller 21) and the radius of the impeller 21 can be obtained. Since the water flow rate flowing into the rotating tube 2 can be measured, the corresponding relationship between the rotation speed of the rotating tube 2 and the radius of the impeller 21 can be obtained through the above calculation formula. Then, according to the rotation speed of the rotating tube 2 (the rotation speed of the impeller 21) required for irrigation, the corresponding radii of the impeller 21 and the rotating tube 2 can be obtained, which can be used to guide the installation model of the rotating tube 2 and the impeller 21 and the matching regulation of the irrigation injection speed (the rotation speed of the impeller 21).

[0031] like Figure 1 and Figure 5As shown, a limiting ring 3 is provided on the outer periphery of the rotating tube 2, a support rod 11 is fixedly connected between the limiting ring 3 and the water inlet pipe 1, a rotating gear 231 is fixedly connected above the limiting ring 3 on the outer periphery of the reciprocating threaded rotating tube 23, and a tooth groove 31 meshing with the rotating gear 231 is provided on the top surface of the limiting ring 3.

[0032] By setting the limiting ring 3, the limiting ring 3 is sleeved on the outer periphery of the rotating tube 2, and the inner wall of the limiting ring 3 does not contact the outer periphery of the rotating tube 2. Figure 1 The status of the limiting ring 3 and the rotating tube 2 can be seen. When the rotating tube 2 is in a rotating state, it can drive the reciprocating threaded rotating tube 23 to be in a rotating state, and then drive the rotating gear 231 to rotate. At this time, under the limitation of the tooth groove 31, the rotating gear 231 can be in a rotating state, so that the rotating gear 231 drives the reciprocating threaded rotating tube 23 to rotate by itself.

[0033] Supplement: The rotating gear 231 can rotate with the rotation of the rotating tube 2. Since the outer periphery of the rotating gear 231 is meshed and connected in the tooth groove 31, and the tooth groove 31 is opened on the top surface of the limiting ring 3, the limiting ring 3 is fixed on the water inlet pipe 1 through the support rod 11, so that the limiting ring 3 is in a stationary state. Therefore, when the rotating gear 231 rotates around the limiting ring 3, the rotating gear 231 can drive the reciprocating threaded rotating tube 23 to rotate by itself under the limiting action of the tooth groove 31.

[0034] like Figure 1 and Figure 5 As shown, a limiting mechanism for limiting the position of the telescopic sleeve 4 is arranged above the top end of the rotating tube 2 corresponding to the telescopic sleeve 4, and the limiting mechanism includes a limiting support rod 22, a limiting guide rod 221 and a guide plate 41. The guide plate 41 is fixedly arranged on the periphery of the telescopic sleeve 4, the limiting support rod 22 is fixedly connected to the top end of the rotating tube 2, the limiting guide rod 221 is fixedly arranged at one end of the limiting support rod 22, and a limiting groove 411 is opened on the top surface of the guide plate 41 for the limiting support rod 22 to slide left and right.

[0035] The telescopic sleeve 4 can be limited by the setting of the limiting support rod 22 and the limiting guide rod 221, wherein the limiting guide rod 221 is slidably set in the limiting groove 411, and the guide plate 41 is fixedly set on the telescopic sleeve 4, so that the telescopic sleeve 4 can be ensured to be in a horizontal moving state when moving left and right.

[0036] Among them, under the limiting action of the limiting guide rod 221, when the reciprocating threaded rotating tube 23 is in a rotating state, it can drive the telescopic sleeve 4 to move left and right around the periphery of the reciprocating threaded rotating tube 23, which can avoid the telescopic sleeve 4 from rotating and improve the stability of movement.

[0037] like Figure 2 and Figure 6As shown, the support mechanism includes a guide plate 42 and a support tube 421. The guide plate 42 is fixedly connected to one end of the telescopic sleeve 4. The support tube 421 is symmetrically connected to the guide plate 42. The ends of the support tube 421 are fixedly connected to the first support rods 511. The first support rods 511 are rotatably connected to the first connecting frame 51 between adjacent ones through bearings. The first connecting frame 51 is fixedly connected to the inner wall of the first arc edge gear 5.

[0038] By setting the guide plate 42 and the support tube 421, the first arc-edge gear 5 can be supported, and the rotation connection is carried out by using bearings to facilitate water circulation, wherein the water in the telescopic sleeve 4 enters the guide plate 42 and then enters the support tube 421, and then flows into the first support rod 511, thereby realizing water circulation and effectively supporting the first arc-edge gear 5.

[0039] like Figure 6 As shown, the irrigation mechanism includes a second connecting frame 71 and a second support rod 711. The second connecting frame 71 is a cross-shaped structure fixedly arranged on the inner wall of the second arc-edge gear 7. The bottom surface of the second connecting frame 71 is provided with a water spray hole 712 for irrigating and sprinkling water into the farmland. The second support rod 711 is rotatably arranged at the axis center of the bottom surface of the second connecting frame 71, and the power mechanism is arranged between the second support rod 711 and the first support rod 511.

[0040] The second connecting frame 71 can be provided to fix the second arc gear 7 and also facilitate changing the position of the water spray hole 712 and adjusting the water spray range of the water spray hole 712 during the flipping of the second arc gear 7.

[0041] like Figure 2 and Figure 6 As shown, the power mechanism includes a first connecting rod 6, a servo motor 611, a second connecting rod 8, a connecting support plate 9, a first gear 91 and a second gear 92. One end of the first connecting rod 6 is fixedly connected to the bottom end of the first support rod 511, and the other end is fixedly connected to the first support plate 61. One end of the second connecting rod 8 is rotatably connected to the bottom end of the second support rod 711, and the other end of the second connecting rod 8 is fixedly connected to the second support plate 81. The connecting support plate 9 is arranged between the adjacent surfaces of the second support plate 81 and the first support plate 61. The first gear 91 is rotatably arranged on the connecting support plate 9. The first gear 91 is fixedly arranged on the first support plate 61 through a connecting rod. The servo motor 611 is fixedly arranged on the first support plate 61. The power output end of the servo motor 611 is fixedly connected to the connecting support plate 9. The second gear 92 is arranged on the connecting support plate 9, and the second gear 92 is meshed with the first gear 91.

[0042] By starting the servo motor 611, the connecting support plate 9 can be driven to rotate, and the connecting support plate 9 drives the second connecting rod 8 and the second gear 92 to rotate. The second gear 92 rotates around the first gear 91, and then the second connecting rod 8 rotates along the motion trajectory of the second gear 92. Under the connection of the second connecting frame 71 and the second support rod 711, the second arc edge gear 7 can be driven to flip along the first arc edge gear 5 to change the direction of irrigation.

[0043] Among them, the connecting support plate 9 is set as a T-shaped structure, and the servo motor 611 drives the connecting support plate 9 to rotate, so that the connecting support plate 9 rotates with the power output end of the servo motor 611 as the axis. Under the action of the connecting support plate 9, the second support plate 81 can be supported to ensure its movement stability, and the water spray hole 712 is opened on the second connecting frame 71, which can change the water spray direction and the irrigation range during the flipping process of the second arc edge gear 7.

[0044] like Figure 6 As shown, the support tube 421 , the first support rod 511 , the first connecting rod 6 and the first support plate 61 are connected to the second connecting frame 71 , the second support rod 711 , the second connecting rod 8 and the second support plate 81 through the connecting support plate 9 .

[0045] By connecting the support plate 9, the support tube 421, the first support rod 511, the first connecting rod 6, the first support plate 61, the connecting support plate 9, the second connecting frame 71, the second support rod 711, the second connecting rod 8 and the second support plate 81 can be connected, wherein the support tube 421 is connected to the telescopic sleeve 4 through the guide plate 42, so the water entering the telescopic sleeve 4 can be sprayed out from the water spray hole 712 in sequence through the guide plate 42, the support tube 421, the first support rod 511, the first connecting rod 6, the first support plate 61, the connecting support plate 9, the second support plate 81, the second connecting rod 8, the second support rod 711 and the second connecting frame 71 to irrigate the farmland.

[0046] like Figure 6 As shown, the first arc-edge gear 5 and the second arc-edge gear 7 are both fixedly connected to each other with arc-shaped teeth meshing with each other on their peripheries, and the arc-shaped teeth are inclined.

[0047] In the attached Figure 6 It can be seen that arc teeth are arranged on the periphery of the first arc gear 5 and the second arc gear 7, wherein the arc teeth are meshed and connected with each other, and the arc teeth are generally U-shaped in structure, with the two sides arranged in an inclined state. In this way, when the second arc gear 7 is flipped around the periphery of the first arc gear 5, it can rotate, thereby changing the direction of the second connecting frame 71 fixed on the inner wall of the second arc gear 7, thereby changing the position of the water spray hole 712, and further changing the range of the water spray.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
