Technical Field

[0001] The utility model relates to the technical field of sprinkler irrigation equipment, in particular to a guiding device for a parallel-travel sprinkler irrigation machine. Background Art

[0002] With the continuous advancement of agricultural technology, farmland irrigation technology has also developed rapidly. Among them, sprinkler trucks, as an important irrigation equipment, are widely used in farmland irrigation operations.

[0003] Most of the existing parallel-moving sprinkler trucks form roads for the frame to travel by strengthening the foundation on both sides of the canal. During the sprinkler operation, the frame will move along the set path on the road. During this process, the deflection of the frame can be achieved through the preset track. Although this method can prevent the sprinkler truck from deflecting during the movement, this method requires a high investment cost and is more troublesome to construct, and it also reduces the flexibility of the sprinkler machine.

[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1-6 As shown, a guide device for a parallel-travel sprinkler comprises a guide frame that travels with a frame 1, and a guide wire 2 installed on the ground and used in conjunction with the guide frame. The guide frame comprises a mounting seat 3 connected to the frame 1, and a feeler rod 4 used in conjunction with the guide wire 2 is provided at the lower portion of the mounting seat 3. The feeler rod 4 is fitted with the guide wire 2 to guide the travel path of the frame 1 during travel, thereby preventing the frame 1 from deviating from the original path during travel. Compared with the existing frame 1, the travel path of the frame 1 is guided by the contact between the feeler rod 4 and the guide wire 2, so that the travel deviation can be corrected in a timely and effective manner, thereby ensuring the smooth advancement of the frame 1.

[0026] It should be noted that a positioning bracket for fixing the guide frame is provided on the side wall of the frame 1, and the positioning bracket includes a cross brace 18 fixedly connected to the side wall of the frame 1, a first bracket 19 is provided on the upper part of the cross brace 18, and a second bracket 20 is provided on the lower part. A V-shaped clip plate 21 connected to the guide frame is provided at the end of the first bracket, and a U-shaped clip plate 22 connected to the guide frame is provided at the end of the second bracket 20. The multi-point support of the V-shaped clip plate 21 and the U-shaped clip plate 22 can improve the connection stability between the guide frame and the frame 1.

[0027] A correction control box 5 is provided on the side wall of the mounting seat 3, and a travel switch connected to the feeler rod 4 is provided in the correction control box 5. There are two feeler rods 4 and they are symmetrically distributed with the plane where the guide wire 2 is located as the axis. The middle parts of the two feeler rods 4 are fitted together, and a V-shaped limit groove 7 is formed at the lower part. The upper parts of the two feeler rods 4 are connected with the travel switch in the correction control box 5. When the frame 1 deviates during the movement of the frame 1, the guide wire 2 contacts the feeler rod 4 and triggers the corresponding travel switch, thereby controlling the frame 1 to perform steering operations and correcting the travel direction of the frame 1. The travel trajectory of the trolley is corrected through the cooperation of the correction control box, the feeler rod and the guide wire. Compared with the conventional wheel speed sensor correction method or the visual sensor correction method, the correction equipment has a simpler structure and is more suitable for relatively bumpy roads in the field, which simplifies the operation difficulty and is convenient for practical promotion.

[0028] The end of the guide wire 2 is provided with a limit baffle 8 used in conjunction with the feeler rod 4, the front end of the limit baffle is provided with a support rod 23 for fixing the wire 2, the top of the support rod 23 is provided with a V-shaped spring locator 24 for fixing the guide wire 2, and the open end of the V-shaped spring locator 24 is passed through the top of the support rod 23. The limit baffle 8 is triangular and gradually extends outward from the end connected to the feeler rod 4. When the frame 1 reaches the key position of the guide wire 2, the other feeler rod 4 will contact the limit baffle 8 at the same time, and then move along the trajectory of the hypotenuse of the limit baffle 8. At this time, the two feelers 4 are separated from the guide wire 2 at the same time, and the frame 1 stops moving forward.

[0029] The mounting base 3 includes a base plate 9, on which a slide groove 10 for adjusting the deviation correction control box 5 is provided. By adjusting the position of the deviation correction control box 5 on the base plate 9, it is possible to ensure that the guide wire 2 is located in the middle of the limit groove 7 at the initial position. A vertical rod 11 is provided on the upper part of the base plate 9, and an extension rod 12 connected to the frame 1 is provided at the upper end of the vertical rod 11. The extension rod 12 extends to both ends of the frame 1, and can correct and guide the frame 1 at the front end of the frame 1 in the direction of travel.

[0030] There are two guide frames, both of which extend to the outside of both ends of the frame 1 through extension rods 12 .

[0031] Both ends of the guide wire 2 are provided with positioning rods 13, and one side of the positioning rod 13 is provided with a tensioner 14 connected to the guide wire 2. The tensioner 14 includes an adjusting sleeve, and both ends of the adjusting sleeve are provided with adjusting rods. One end of the adjusting rod is connected to the adjusting sleeve, and the other end is connected to the guide wire 2. The adjusting sleeve is used to adjust the tension of the guide wire 2 to keep it in a taut state. The other side is provided with a pull rod 15 connected to the ground, and a tensioner is also provided in the middle of the connecting rod 15. The main function of the positioning rod 13 is to position the end of the guide wire 2.

[0032] An L-shaped limit plate 16 is provided on the upper part of the positioning rod 13, and a contact switch 17 corresponding to the position of the L-shaped limit plate 16 is provided on the side wall of the mounting seat 3. After the L-shaped limit plate 16 contacts the contact switch 17, the frame 1 stops moving forward, and cooperates with the limit baffle 8 to limit the travel distance of the frame 1.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
