Description

Technical Field

[0001] This invention belongs to the field of agricultural sprinkler irrigation machinery technology, specifically relating to a slope-adaptive tower vehicle and large-scale sprinkler irrigation equipment. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Large sprinkler irrigation machines have significant advantages in agricultural water-saving irrigation, especially in sloping land irrigation, where they effectively solve the problem of uneven irrigation that cannot be achieved by traditional flood irrigation and ditch irrigation.

[0004] However, the inventors discovered that due to the large span of large sprinkler irrigation machines, the undulation of the field surface has a significant impact on the stability of the sprinkler irrigation machine. When the difference in the slope of the field surface reaches more than 10°, the span connection of the existing sprinkler irrigation machine will detach or collapse due to excessive torsion, which reduces the adaptability of the sprinkler irrigation machine to the complex surface environment of large-area fields. Summary of the Invention

This device takes into account the actual needs of large sprinkler irrigation machines operating in fields with steep slopes.

[0021] The beneficial effects of the present invention are as follows:

[0022] The slope-adaptive tower vehicle of the present invention is equipped with a rotating main pipe, which is connected to the water supply pipe of the adjacent span. The rotating main pipe can be driven to rotate by an electric push rod. The rotation angle of the rotating main pipe is actively controlled by the slope information fed back by the angle measurement sensor set on the crossbeam of the tower vehicle. This avoids excessive torsion at the connection of adjacent spans caused by large differences in the slope of the field surface, prevents span separation and span collapse, and effectively improves the adaptability and stability of large sprinkler irrigation equipment in operation on steep slopes.

[0023] The slope-adaptive tower truck of this invention features a rotating main pipe connected to the water supply pipes of adjacent spans. An electric actuator drives the first and second supports to rotate, which in turn rotates the rotating main pipe. The rotation angle of the main pipe is actively controlled by slope information fed back from angle measurement sensors mounted on the tower truck's crossbeam. This prevents excessive twisting at the connection points of adjacent spans due to significant differences in field slope, thus preventing span detachment and collapse. This effectively improves the adaptability and stability of large-scale sprinkler irrigation equipment operating on steep slopes. Furthermore, when the tower truck is on a slope, rotating the first and second supports keeps them relatively vertical, resolving the issue of the tower truck's center of gravity shifting and making the tower truck's movement safer and more stable.

[0024] The slope-adaptive tower vehicle of the present invention connects the rotating main pipe and the connecting main pipe through a concave spherical connecting seat and a spherical connecting seat, and is equipped with a limit anti-detachment device. The rotating main pipe and the connecting main pipe form a multi-degree-of-freedom flexible connection. Since the rotating main pipe and the connecting main pipe are placed between adjacent spans, a multi-degree-of-freedom flexible connection between spans is realized, further avoiding the current situation of detachment and ensuring the stability of the sprinkler equipment.

[0047] Example 1

[0048] In a typical embodiment of the present invention, such as Figure 1 As shown, a slope-adaptive tower vehicle is proposed, which includes a traveling wheel 3, a crossbeam 4, an angle measurement sensor 5, a bracket, an electric push rod 7, a pipe clamp, a rotating main pipe 9, etc.

[0049] The crossbeam 4 is horizontally set, and both ends of the crossbeam 4 are equipped with traveling wheels 3, which facilitate the movement of the entire tower vehicle.

[0050] Angle measuring sensor 5 is installed and fixed on crossbeam 4 to detect the horizontal angle of the crossbeam.

[0051] Both ends of the crossbeam 4 are fixedly connected to one end of the first bracket 6, and the other end of the first bracket 6 is fixedly connected to the first pipe clamp 8; the first bracket 6 is set at an angle, the first pipe clamp 8 is placed above the crossbeam 4, and the first brackets 6 at both ends of the crossbeam 4 are both tilted upward and fixedly connected to the same first pipe clamp 8.

[0052] The first support 6 is a rod-shaped structure. The number of first supports 6 can be set to multiple. Multiple first supports 6 can be fixed at both ends of the crossbeam 4; or one first support can be fixed at both ends of the crossbeam 4 and one first support can be fixed in the middle of the crossbeam 4 to provide sufficient support for the first pipe clamp.

[0053] Both ends of the crossbeam 4 are fixedly connected to one end of the second bracket 14, and the other end of the second bracket 14 is fixedly connected to the second pipe clamp 15. The second bracket 14 is set at an angle, and the second pipe clamp 15 is placed above the crossbeam 4. The second brackets 14 at both ends of the crossbeam 4 are both tilted upward and fixedly connected to the same second pipe clamp 15.

[0054] The second support 14 is a rod-shaped structure. The number of second supports 14 can be set to multiple. Multiple second supports 14 can be fixed at both ends of the crossbeam 4; or one second support can be fixed at both ends of the crossbeam 4 and one second support can be fixed in the middle of the crossbeam 4 to provide sufficient support for the second pipe clamp.

[0055] Furthermore, the first support 6 and the second support 14 located at the same end of the crossbeam 4 have a certain included angle; the first pipe clamp 8 and the second pipe clamp 15 are set at the same height, and there is a certain interval between the first pipe clamp 8 and the second pipe clamp 15.

[0056] A rotating main pipe 9 is provided between the first pipe clamp 8 and the second pipe clamp 15, and both the first pipe clamp 8 and the second pipe clamp 15 are rotatably connected to the rotating main pipe 9. The first pipe clamp 8 is close to one end of the rotating main pipe 9, and the second pipe clamp 15 is close to the other end of the rotating main pipe 9. The rotating main pipe 9 is horizontally arranged and perpendicular to the crossbeam 4.

[0057] An electric push rod 7 is provided between the rotating main tube 9 and the first bracket 6 and the second bracket 14. The electric push rod 7 is perpendicular to the axis of the rotating main tube 9. In a specific configuration, one end of an electric push rod 7 is hinged to one of the first brackets 6, and the other end of the electric push rod 7 is hinged to the rotating main tube 9. One end of another electric push rod 7 is hinged to one of the second brackets 14, and the other end of the electric push rod 7 is hinged to the rotating main tube 9.

[0058] When the rotating main tube is driven to rotate clockwise or counterclockwise, both electric push rods are driven to rotate by pushing and pulling, making the overall force and movement more stable and reliable.

[0059] like Figures 2-4 As shown, the first pipe clamp 8 and the second pipe clamp 15 have the same structure, both including an upper pipe clamp 12 and a lower pipe clamp 13 arranged opposite to each other, and the upper pipe clamp 12 and the lower pipe clamp 13 are fixedly connected; wherein, the upper pipe clamp 12 includes a sliding friction pad 12-1 and a pipe clamp seat 12-2, the pipe clamp seat 12-2 is semi-circular, and the sliding friction pad 12-1 is fixedly installed on the inner side of the pipe clamp seat 12-2; the lower pipe clamp 13 includes a sliding friction pad 13-1, a pipe clamp seat 13-2, and a connecting seat 13-3, the pipe clamp seat 13-2 is semi-circular, the sliding friction pad 13-1 is fixedly installed on the inner side of the pipe clamp seat 13-2, and two connecting seats 13-3 are provided, and the two connecting seats 13-3 are respectively fixedly connected to the outer side of the pipe clamp seat 13-2.

[0060] The upper pipe clamp 12's clamp seat 12-2 and the lower pipe clamp 13's clamp seat 13-2 form a ring with each other and are fixedly connected. The rotating main pipe 9 is installed between the two clamp seats and contacts the outer wall of the rotating main pipe with a sliding friction pad. In a specific setting, the clamp seats of the upper and lower pipe clamps have ear plates on both sides. The ear plates of the upper and lower pipe clamp clamp seats can be fixedly connected by bolts or other fasteners. The connecting seat 13-3 is fixedly set on both sides of the clamp seat of the lower pipe clamp. The connecting seat 13-3 is fixedly connected to the first bracket 6 or the second bracket 14. The connecting surface of the connecting seat 13-3 and the bracket is inclined so as to reliably connect with the inclined bracket.

[0061] like Figure 5 As shown, the rotating main pipe 9 includes a water supply pipe 9-1, a flange 9-2, a mounting groove 9-3, a push rod mounting seat 9-4, a support frame 9-5, and a concave spherical connecting seat 9-6.

[0062] Two mounting grooves 9-3 are provided on the outer surface of the water supply pipe 9-1. The mounting grooves 9-3 are annular grooves and are set at a certain distance apart. The distance between the two mounting grooves is the same as the distance between the first pipe clamp and the second pipe clamp. The upper and lower pipe clamps of the first pipe clamp are installed in one of the mounting grooves, and the upper and lower pipe clamps of the second pipe clamp are installed in the other mounting groove. The first and second pipe clamps are rotatably connected to the rotating main pipe 9.

[0063] Two push rod mounting seats 9-4 are fixedly installed at the bottom of the water pipe 9-1. The two push rod mounting seats 9-4 are set at a certain distance apart. One of the push rod mounting seats 9-4 is hinged to the extended end of the electric push rod 7 located on the first bracket 6, and the other push rod mounting seat 9-4 is hinged to the extended end of the electric push rod 7 located on the second bracket 14.

[0064] A flange 9-2 is installed at one end of the water supply pipe 9-1, and a support frame 9-5 is fixedly installed at the other end of the water supply pipe 9-1. A concave spherical connector 9-6 is fixedly installed at the end of the support frame 9-5, and both the upper and lower surfaces of the concave spherical connector 9-6 are concave spherical.

[0065] One end of the rotating main tube 9, which is provided with a support frame 9-5, is connected to the connecting main tube 10; for example... Figure 7 As shown, the main connecting pipe 10 includes a water supply pipe 10-1, a flange 10-2, a support frame 10-3, a spherical connector 10-4, and a limiter / anti-detachment device 10-5. The flange 10-2 is installed at one end of the water supply pipe 10-1, and the support frame 10-3 is fixedly installed on the outer wall of the other end of the water supply pipe 10-1. The spherical connector 10-4 is installed on the support frame 10-3, and the spherical connector 10-4 is designed as a convex spherical shape.

[0066] The support frame 10-3 is also equipped with a limit anti-detachment device 10-5. The upper part of the limit anti-detachment device 10-5 is also set as a convex spherical shape. The limit anti-detachment device 10-5 is threadedly connected to the support frame 10-3. The limit anti-detachment device 10-5 maintains an appropriate gap with the concave spherical surface of the concave spherical connecting seat 9-6.

[0067] The flange 9-2 of the rotating main pipe 9 and the flange 10-2 of the connecting main pipe 10 are used to connect with other water supply pipes on the cross rack. The other water supply pipes on the cross rack are all water supply pipe structures with flanges at both ends.

[0068] like Figure 2 As shown, the water supply pipe 9-1 of the rotating main pipe 9 and the water supply pipe 10-1 of the connecting main pipe 10 are flexibly connected by a connecting hose 11; the spherical connecting seat 10-4 of the connecting main pipe 10 is in contact with the upper concave spherical surface of the concave spherical connecting seat 9-6 of the rotating main pipe 9, and the limiting anti-detachment device 10-5 cooperates with the lower concave spherical surface of the concave spherical connecting seat 9-6. By adjusting the limiting anti-detachment device 10-5 and the lower concave spherical surface of the concave spherical connecting seat 9-6 to maintain an appropriate gap, the anti-detachment can be achieved by the spherical connecting seat 10-4 and the limiting anti-detachment device 10-5 cooperating with the upper and lower concave spherical surfaces of the concave spherical connecting seat 9-6 respectively. In the static state, the spherical connecting seat 10-4 is in contact with the upper concave spherical surface of the concave spherical connecting seat 9-6 and plays the role of supporting the strut, while the limiting anti-detachment device 10-5 and the lower concave spherical surface of the concave spherical connecting seat 9-6 have an appropriate gap.

[0069] Since both the upper and lower surfaces of the concave spherical connector 9-6 are concave spherical, the center of the concave spherical connector 9-6 is thin and gradually thickens outward in a curved form. When the limit anti-detachment device 10-5 is installed and tightened, if the gap between the upper spherical surface of the limit anti-detachment device 10-5 and the spherical connector 10-4 is less than the minimum detachment value of the thickness of the concave spherical connector 9-6, the concave spherical connector 9-6 will not detach from the spherical connector 10-4 and the limit anti-detachment device 10-5.

[0070] The gap between the upper spherical surface of the limit anti-detachment device 10-5 and the spherical connecting seat 10-4 is greater than the thickness of the concave spherical connecting seat 9-6 within a certain range outward from the center. Therefore, in three-dimensional space, the concave spherical connecting seat 9-6 can achieve a certain distance of relative displacement and a certain angle of relative rotation between the spherical connecting seat 10-4 and the limit anti-detachment device 10-5, realizing a multi-degree-of-freedom flexible connection between the rotating main tube 9 and the connecting main tube 10, and they will not detach from each other.

[0071] In actual operation, the spans of a large sprinkler irrigation machine do not move synchronously, but move sequentially in conjunction. Furthermore, ground undulations and slope differences will change the spatial position and distance between adjacent tower vehicles. Through the cooperation of the spherical connecting seat, the limit anti-detachment device, and the concave spherical connecting seat, space for relative movement can be left to compensate for the distance.

[0072] The working principle of this tower crane is as follows:

[0073] like Figure 1 As shown, during field operations, the angle measuring sensor 5 of the tower vehicle's crossbeam 4 detects the horizontal angle of the crossbeam 4. If the horizontal angle of the crossbeam 4 is detected to be at an angle with the initial set angle, it indicates that the tower vehicle is on a sloping field surface. The electric push rod 7 is then pushed out to drive the rotating main tube 9 to rotate by the corresponding angle.

[0074] For example, taking a horizontal angle change of 5° as an adjustment span, when the angle measurement sensor 5 on the crossbeam 4 of the tower crane reports an angle between 5° and 10°, it means that the ground where the tower crane is located has a slope of that angle. According to the direction of the ground slope, the electric push rod 7 drives the rotating main pipe 9 to rotate in the opposite direction to 5° (relative to the initial position angle); when the angle measurement sensor 5 on the crossbeam 4 of the tower crane reports an angle between 10° and 15°, according to the direction of the ground slope, the electric push rod 7 drives the rotating main pipe 9 to rotate in the opposite direction to 10° (relative to the initial position angle).

[0075] Example 2

[0076] In another typical embodiment of the present invention, such as Figure 7 As shown, a large-scale sprinkler irrigation equipment is proposed, which includes a tower vehicle 1 and spanning frames 2 as described in Embodiment 1. Multiple spanning frames 2 are provided, and each spanning frame 2 is installed and connected to the tower vehicle 1. The tower vehicle 1 is arranged between adjacent spanning frames 2.

[0077] The connecting main pipe 10 is located at the end of the span 2, and the connecting main pipe 10 is connected to the rotating main pipe 9 via the connecting hose 11. Other water supply pipes with flanges at both ends are installed on the span 2. The flange 10-2 of the connecting main pipe 10 is connected to the end of other water supply pipes on the next span, and the flange 9-2 of the rotating main pipe 9 is connected to the end of other water supply pipes on the previous span.

[0078] Since the rotating main pipe 9 can rotate according to the slope information fed back by the angle measuring sensor 5, and the spans 2 are connected by the rotating main pipe 9, when the sprinkler irrigation equipment is installed on the sloping field surface, the angle of the span connection can be adjusted according to the slope to prevent excessive twisting of the adjacent span connection due to the large difference in the slope of the field surface.

[0079] Example 3

[0080] In another typical embodiment of the present invention, such as Figure 8 As shown, a slope-adaptive tower vehicle is proposed, which includes a traveling wheel 3, a crossbeam 4, an angle measurement sensor 5, an electric push rod 7, a bracket, a pipe clamp, a rotating main pipe 9, etc.

[0081] The arrangement of the walking wheel 3, crossbeam 4, and angle measurement sensor 5 is the same as in Example 1.

[0082] The support includes a first support 6 and a second support 14. The bottom of both the first support 6 and the second support 14 are hinged to the middle of the crossbeam 4. The top of the first support 6 is fixedly connected to the first pipe clamp 8, and the top of the second support 14 is fixedly connected to the second pipe clamp 15.

[0083] Both the first support 6 and the second support 14 are quadrilateral structures. One corner of the quadrilateral structure is located at the bottom, and another corner is located at the top. The bottom corner of the quadrilateral structure is hinged to the middle of the crossbeam 4, and the top corner of the quadrilateral structure is fixedly connected to the pipe clamp.

[0084] Specifically, the first and second supports are hinged to both sides of the crossbeam, and both the first and second supports are connected by multiple rods to form a quadrilateral structure; the angle of the side of the two supports that is hinged to the crossbeam is greater than the angle of the side of the two supports that is connected to the pipe clamp, and the specific angle can be set according to the actual size and stability requirements.

[0085] The first pipe clamp 8 and the second pipe clamp 15 are set at the same height, and there is a certain gap between the first pipe clamp 8 and the second pipe clamp 15. A rotating main pipe 9 is provided between the first pipe clamp 8 and the second pipe clamp 15, and both the first pipe clamp 8 and the second pipe clamp 15 are fixedly connected to the rotating main pipe 9.

[0086] An electric push rod 7 is provided between the crossbeam 4 and the lower part of at least one side of the first support 6 and the second support 14. The electric push rod 7 is perpendicular to the axis of the rotating main tube 9. One end of the electric push rod 7 is hinged to the crossbeam 4, and the other end of the electric push rod 7 is hinged to the lower part of the first support and the second support respectively.

[0087] In this embodiment, two electric push rods 7 are provided. The two electric push rods are respectively placed on the lower sides of the first bracket and the second bracket and between the crossbeam. By synchronously driving the first bracket and the second bracket to rotate through the two electric push rods, the stability of the overall structure can be improved.

[0088] In a preferred embodiment, the first support 6 and the second support 14 are connected by a connecting rod 16 to enhance the overall integrity and stability of the structure. A fixing frame 17 is provided between the connecting rod 16 and the bottom corners of the first support 6 and the second support 14. The middle part of the fixing frame 17 is hinged to one end of the electric push rod 7, thereby providing the electric push rod with a larger operating space while enhancing the structural stability. The positions of the connecting rod 16 and the fixing frame 17 on the first and second supports can be adjusted according to requirements.

[0089] In this embodiment, compared with Embodiment 1, the bottom of the water supply pipe 9-1 of the rotating main pipe 9 is no longer provided with a push rod mounting seat; otherwise, it is the same as Embodiment 1.

[0090] The first clamp 8 and the second clamp 15 are installed in the mounting groove 9-2 of the rotating main pipe 9 and are fixedly connected to the rotating main pipe 9.

[0091] The connection main pipe, the connection hose, and their fit with the rotating main pipe are all the same as in Example 1.

[0092] The working principle of this tower crane is as follows:

[0093] like Figure 1 As shown, during field operations, the angle measuring sensor 5 of the tower vehicle's crossbeam 4 detects the horizontal angle of the crossbeam 4. If the horizontal angle of the crossbeam 4 is detected to be at an angle with the initial set angle, it indicates that the tower vehicle is on a sloping field surface. The electric push rod 7 is then pushed out to drive the first support 6 and the second support 14 to rotate by the corresponding angle. The support is fixedly connected by the pipe clamp and the rotating main pipe, which drives the rotating main pipe to rotate.

[0094] For example, taking a horizontal angle change of 5° as an adjustment span, when the angle measurement sensor 5 on the crossbeam 4 of the tower vehicle feedback angle is between 5° and 10°, it means that the ground where the tower vehicle is located has a slope of that angle. According to the direction of the ground slope, the electric push rod 7 drives the first support 6 and the second support 14 to rotate in the opposite direction to 5° (relative to the initial position angle), and the rotating main tube 9 rotates by the same angle accordingly. When the angle measurement sensor 5 on the crossbeam 4 of the tower vehicle feedback angle is between 10° and 15°, according to the direction of the ground slope, the electric push rod 7 drives the first support 6 and the second support 14 to rotate in the opposite direction to 10° (relative to the initial position angle).

[0095] Example 4

[0096] In another typical embodiment of the present invention, such as Figure 11 As shown, a large-scale sprinkler irrigation equipment is proposed, which includes a tower vehicle 1 and spanning frames 2 as described in Embodiment 3. Multiple spanning frames 2 are provided, and each spanning frame 2 is installed and connected to the tower vehicle 1. The tower vehicle 1 is arranged between adjacent spanning frames 2.

[0097] The connecting main pipe 10 is located at the end of the span 2, and the connecting main pipe 10 is connected to the rotating main pipe 9 via the connecting hose 11. Other water supply pipes with flanges at both ends are installed on the span 2. The flange 10-2 of the connecting main pipe 10 is connected to the end of other water supply pipes on the next span, and the flange 9-2 of the rotating main pipe 9 is connected to the end of other water supply pipes on the previous span.

[0098] Since the first and second supports can rotate according to the slope information fed back by the angle measuring sensor 5, thereby driving the rotating main pipe 9 to rotate, and the spans 2 are connected by the rotating main pipe 9, when the sprinkler irrigation equipment is installed on the sloping field surface, the angle of the span connection can be adjusted according to the slope to prevent excessive twisting of the adjacent span connection due to the large difference in the slope of the field surface.

[0099] In addition, when the tower crane is on a sloped surface, the center of gravity of the first and second supports shifts. After rotating the first and second supports, they will remain in a relatively vertical position, solving the problem of the tower crane's center of gravity shift and making the tower crane travel more safely and stably.

[0100] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
