DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model is clearly and completely described below in conjunction with specific embodiments.

[0027] like Figure 1-Figure 9 A hydraulic telescopic tail plow shown in the figure comprises a mounting frame 1, a mounting plate 2 for connecting to the plow frame is fixedly provided at one end of the mounting frame 1, a U-shaped support frame 3 is fixedly provided perpendicularly to each other at the other end of the mounting frame 1, plow legs 6 are symmetrically hinged on both sides of the support frame 3, and plow blades 7 are installed on the plow legs 6;

[0028] A mounting column 5 is fixedly provided above one end of the mounting frame 1 close to the support frame 3, and a telescopic cylinder 16 is installed on the upper part of the mounting column 5 close to the support frame 3. The telescopic rod 17 of the telescopic cylinder 16 is fixedly connected to the adjustment block 10 located below the telescopic cylinder 16, and a support rod 15 is hinged between each side of the adjustment block 10 and the plow leg 6.

[0029] After the hydraulic telescopic tail plow is installed on the plow frame of the flip plow, the plow blade 7 can be opened and closed under the drive of the telescopic cylinder 16. When the tail plow is needed, the telescopic rod 17 is extended, and under the action of the support rod 15, the plow legs 6 are opened outward, and can be opened to a maximum angle parallel to the support frame 3. When the tail plow is not needed, the telescopic rod 17 is retracted, driving the plow legs 6 to retract inward, reducing the need for manual operation and improving the adaptability and flexibility of the operation.

[0030] like Figure 2 , Figure 4 and Figure 6 As shown, in this embodiment, the support frame 3 is opened upward and includes a horizontal plate 301 and two vertical plates 302; the mounting column 5 and the length direction of the support frame 3 are perpendicular to each other, and the mounting column 5 and the vertical plates 302 of the support frame 3 are parallel to each other.

[0031] As a further optimization, the tail end of the plow leg 6 is rotatably hinged between the two vertical plates 302 on the support frame 3 through a rotating shaft 8, and the plow blade 7 is installed at the head end of the plow leg 6. When the two plow legs 6 are parallel to the support frame 3, a gap is left between the tail ends of the two plow legs 6, and the tail ends of the two plow legs 6 are cubic; a square limit block 9 is fixed at the lower end of the adjustment block 10, and the size of the limit block 9 is adapted to the gap between the tail ends of the two plow legs 6 (when the plow leg 6 and the support frame 3 are parallel to each other); convex guide grooves 11 are opened on both sides of the adjustment block 10 along the length direction, and a guide block 12 is clamped in the guide groove 11, a first bracket 13 is fixed on the guide block 12, and a second bracket 14 is fixed on the plow leg 6, and the two ends of the support rod 15 are respectively hinged to the first bracket 13 and the second bracket 14; blocks 19 corresponding to the plow legs 6 are fixed on the upper parts of both sides of the mounting column 5, and when the plow leg 6 rotates, the block 19 is used to limit the position.

[0032] By fixing a limit block 9 at the lower part of the adjustment block 10, after the plow blade 7 is fully opened, as the telescopic rod 17 is further extended, the limit block 9 can be stuck in the gap between the rear ends of the two plow legs 6, thereby enhancing the fixing effect of the plow legs 6. Even if the telescopic cylinder 16 fails, the plow legs 6 can remain in the open state under the action of the limit block 9, and the overall structure of the tail plow is more reliable.

[0033] As a further optimization, a square clearance groove 4 is opened in the middle of the horizontal plate 301 of the support frame 3 to prevent interference between the rear end of the plow leg 6 and the horizontal plate 301 when the plow leg 6 rotates around the rotating shaft 8.

[0034] As a further optimization, a guide plate 18 is fixedly provided between the two vertical plates 302 of the support frame 3 on both sides of the limit block 9. The spacing between the two guide plates 18 is adapted to the width of the limit block 9. The height of the guide plate 18 is reasonably set so that as the telescopic rod 17 moves, a part of the limit block 9 is always located between the two guide plates 18.

[0035] Both ends of the rotating shaft 8 are fixed on the support frame 3, and the tail of the plow leg 6 is provided with a through hole corresponding to the rotating shaft 8. Since the horizontal plate 301 is provided with a clearance groove 4, the structural strength of the support frame 3 is reduced. By fixing the rotating shaft 8 between the two vertical plates 302, the structural strength of the support frame 3 can be enhanced.

[0036] As a further optimization, the support rod 15 is a threaded adjustment rod with adjustable length.

[0037] In this embodiment, the mounting frame 1 is composed of a mounting portion 101 and a bending portion 102 , an obtuse angle is formed between the mounting portion 101 and the bending portion 102 , the mounting plate 2 is arranged at the free end of the mounting portion 101 , and the support frame 3 is arranged at the free end of the bending portion 102 .

[0038] Specific working process:

[0039] When the tail plow needs to be used, the telescopic rod 17 is extended by the telescopic oil cylinder 16, and the support rod 15 drives the plow legs 6 to open. During the opening process, under the action of gravity, the guide block 12 is always located at the lowermost end of the guide groove 11 until the plow legs 6 and the support frame 3 are parallel to each other, and then the telescopic rod 17 continues to extend, driving the limit block 9 to move downward along the two guide plates 18 and enter the gap between the tail ends of the two plow legs 6. Since the tail ends of the plow legs 6 are cubic, the limit block 9 just clamps the two plow legs 6 at this time, and the guide block 12 just slides to the uppermost position in the guide groove 11, so that the guide block 12 cannot slide in the guide groove 11;

[0040] When the tail plow is not needed, the telescopic rod 17 is driven to retract by the telescopic cylinder 16. As the telescopic rod 17 moves upward, the limit block 9 gradually disengages from the gap between the tail ends of the two plow legs 6. At the same time, the guide block 12 moves downward relative to the guide groove 11. When the limit block 9 completely disengages from the gap between the tail ends of the two plow legs 6, the guide block 12 is located at the lowermost position of the guide groove 11. As the telescopic rod 17 continues to retract, the support rod 15 drives the two plow legs 6 to merge upward until the plow legs 6 stop moving after contacting the stop block 19. Since the guide block 12 is located at the lowermost position in the guide groove 11 at this time, the guide block 12 cannot slide in the guide groove 11 either.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
