[0020] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figures 1-4 As shown in the figure, this embodiment provides a hydraulic lifting and adjusting device for large agricultural machinery, which includes a support frame 1 and an agricultural machinery body 2. A hydraulic lifting mechanism 3 is provided between the support frame 1 and the agricultural machinery body 2. The hydraulic lifting mechanism 3 includes multiple first fixing plates 4 fixedly installed at the bottom of the support frame 1. A hydraulic cylinder 5 connected to the agricultural machinery body 2 is fixedly installed on the first fixing plate 4. Multiple first sliding grooves 6 are provided at the bottom of the support frame 1 and the top of the agricultural machinery body 2. A first slider 7 is slidably installed inside the first sliding groove 6. Two folding frames 8 symmetrically arranged on the support frame 1 and the agricultural machinery body 2 and movably connected to the first slider 7 are provided.

[0022] In this embodiment, as Figures 1-4 As shown, two protective shells 9 are symmetrically fitted onto the hydraulic cylinder 5; the bottom of the first fixing plate 4 has multiple second sliding grooves 10, and a second slider 11 connected to the protective shell 9 is slidably installed inside the second sliding groove 10. Multiple magnetic blocks 12 are provided on the side of the two protective shells 9 that are close to each other. The protective shells 9 can protect the hydraulic cylinder 5 and prevent soil clods from collapsing during tillage operations from affecting the hydraulic cylinder 5; after the second slider 11 is connected to the protective shell 9, the protective shell 9 can slide on the first fixing plate 4. After the two protective shells 9 are pulled apart to both sides, it is convenient to maintain and inspect the hydraulic cylinder 5. At the same time, after the two protective shells 9 are closed, the protective shells 9 can be fixed by the adhesion and adsorption of the multiple magnetic blocks 12, so that they can firmly wrap and protect the hydraulic cylinder 5.

[0023] Multiple grooves 13 are provided on both sides of the first slider 7, and ball bearings 14 that fit against the inner wall of the first slide groove 6 are movably installed inside the grooves 13. The grooves 13 and ball bearings 14 can further reduce the friction between the first slider 7 and the first slide groove 6, so that the first slider 7 can move more easily in the first slide groove 6 to fold the folding frame 8 during the lifting and adjusting process.

[0024] In this embodiment, as Figures 1-4As shown, support plates 15 are fixedly installed on both sides of the agricultural machinery body 2. A movable wheel 16 is provided below the support plate 15. A second fixed plate 17 is provided at the bottom of the support plate 15 and at the top of the movable wheel 16. Multiple shock absorbers 18 are installed between the two second fixed plates 17. The two second fixed plates 17 are connected to the support plate 15 and the movable wheel 16 by bolts 19. Movable wheels 16 are provided on both sides of the agricultural machinery body 2 to assist in its movement. Due to the unevenness of the ground, the movable wheels 16 vibrate during movement. The multiple shock absorbers 18 act as shock absorbers, allowing the movable wheels 16 to move smoothly on the ground and reducing vibration. The bolts 19 allow the two second fixed plates 17 to be removed from the support plate 15 and the movable wheel 16, facilitating the replacement of the shock absorbers 18.

[0025] Both sides of the support frame 1 are provided with limiting plates 20, and the limiting plates 20 have multiple limiting grooves 21. Two limiting blocks 22, which are respectively connected to the support frame 1 and the agricultural machinery body 2, are movably installed on the limiting grooves 21. The limiting plates 20 are connected to the central bearing of the folding frame 8. After the limiting plates 20 are connected to the central axis of the folding frame 8, and the limiting blocks 22 on both sides of the support frame 1 and the agricultural machinery body 2 are connected in the limiting grooves 21, the position of the folding frame 8 can be limited, so that it is always located at the center of both sides of the support frame 1 and the agricultural machinery body 2, and lateral movement is prevented.

[0026] like Figures 1-4 As shown, the working process of the hydraulic lifting and adjusting device for large agricultural machinery provided in this embodiment is as follows: With the hydraulic lifting mechanism 3, the height of the agricultural machinery body 2 can be adjusted by hydraulic lifting. During adjustment, multiple hydraulic cylinders 5 are activated simultaneously to extend their output ends, driving the agricultural machinery body 2 to descend until it is adjusted to a suitable height and then stops. During the extension and adjustment of the hydraulic cylinders 5, the folding frames 8 on both sides are vertically folded in cooperation with the first slide groove 6 and the first slider 7 to assist the hydraulic cylinders 5 in supporting the support frame 1 and the agricultural machinery body 2. After adjustment, tillage operations can be carried out. The overall operation does not require manual disassembly and reassembly for adjustment, which is quick and convenient and helps to improve agricultural production efficiency.

[0027] The foregoing description illustrates and describes preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein. Any modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the protection scope of the appended claims.
