[0022] The utility model is further described in detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides a crawler-type flip plow for agricultural machinery, comprising a connecting frame 1, the rear side of the connecting frame 1 is rotatably connected to a connecting frame 2 3, the connecting frame 2 3 comprises a main beam 31, a connecting block 32 is fixedly installed on the outer side of the main beam 31, a movable beam 33 is movably hinged inside the connecting block 32, a mounting ear 1 34 and a mounting ear 2 35 are respectively fixedly connected to the inner sides of the main beam 31 and the movable beam 33, a modulating oil cylinder 36 is movably hinged on the inner sides of the mounting ear 1 34 and the mounting ear 2 35, a fixing assembly 4 is movably installed on the outer sides of the fixing assembly 4, a walking wheel 5 and a mounting plate 6 are respectively fixedly installed on the outer sides of the fixing assembly 4, and a plow body 7 is fixedly installed on the upper and lower sides of the mounting plate 6.

[0024] The movable beam 33 is driven to rotate along the connecting block 32 by the extension and retraction of the amplitude modulation cylinder 36, so that the movable beam 33 slides along the guide rod 37. The movement of the movable beam 33 can drive the mounting plate 6 installed outside it to move, so as to adjust the angle of the plow body 7. The position of the mounting plate 6 can be adjusted along the movable beam 33 by loosening the fixing component 4, so that the angle between the main beam 31 and the movable beam 33 changes, so as to achieve the widening or narrowing of the tillage width of the plow body 7. The structure is simple and easy to adjust. The locking rib 43 is passed through the through hole 42 from the inner side of the main beam 31 and the movable beam 33, and the locking nut 45 is used to install the outer thread of the limit plate 41 on the outside of the outer thread 44, so that the limit plate 41 is locked and fixed, so as to facilitate the disassembly and assembly of the walking wheel 5 and the mounting plate 6 and the adjustment of the position.

[0025] like Figure 5As shown, the fixing assembly 4 includes a limiting plate 41 and two locking ribs 43. The four corners inside the limiting plate 41 are provided with through holes 42. The ends of the two locking ribs 43 are provided with external threads 44. The two locking ribs 43 are passed through the through holes 42. The external threads of the external threads 44 are installed with locking nuts 45 located on the outside of the limiting plate 41.

[0026] By using the locking rib 43 to pass through the through hole 42 from the inner side of the main beam 31 and the movable beam 33, and by using the locking nut 45 to be installed from the external thread of the limit plate 41 to the outside of the external thread 44, as the locking nut 45 is rotated, the limit plate 41 and the locking rib 43 are almost locked to the outside of the main beam 31 and the movable beam 33, which is convenient for installation and disassembly.

[0027] like Figure 3 As shown, a guide rod 37 is fixedly connected to the rear of the inner side of the main beam 31 , and the movable beam 33 is movably sleeved on the outside of the guide rod 37 .

[0028] A side of the guide rod 37 away from the main beam 31 is fixedly connected to a limiting plate 38 .

[0029] The movable beam 33 can slide along the guide rod 37 , and the movable beam 33 is guided by the guide rod 37 to improve stability, and the movable beam 33 is limited by the limiting piece 38 at the end of the guide rod 37 .

[0030] like Figure 3 As shown, the guide rod 37 is arranged in an arc shape, and the guide rod 37 and the connecting block 32 are arranged coaxially.

[0031] The arc-shaped guide rod 37 is coaxially arranged with the connecting block 32 , so that the movable beam 33 can slide along the guide rod 37 when rotating along the connecting block 32 , thereby improving stability.

[0032] like Figure 5 As shown, the locking rib 43 is arranged in a “U” shape, and the locking rib 43 is clamped on the inner side of the main beam 31 and the movable beam 33 .

[0033] The "U"-shaped locking rib 43 is clamped on the inner side of the main beam 31 and the movable beam 33, so that it passes through the through hole 42 on the limit plate 41 and is locked and fixed. The limit plate 41 cooperates with the locking rib 43 to facilitate its movement along the main beam 31 and the connecting block 32, thereby facilitating the adjustment of the installation and fixing position.

[0034] like Figure 5 As shown, the travel wheel 5 includes an adjustment frame 51 fixedly connected to the outer side of the fixed component 4, and rollers 52 are movably installed on the upper and lower sides of the adjustment frame 51.

[0035] The roller 52 is limited by the adjusting frame 51 by bolt fixing, so that the depth of the plow body can be adjusted.

[0036] like Figure 4 As shown, the connecting frame 1 includes a frame body 11, which is arranged in a "T" shape. The left and right sides of the top of the frame body 11 are fixedly connected with fixing plates 12, and the top of the fixing plate 12 is threadedly installed with fixing bolts 13. The frame body 11 and the main beam 31 are tensioned and hinged with a turning cylinder 2.

[0037] The fixing plate 12 provided on the frame 11 cooperates with the fixing bolts 13 to facilitate the main beam 31 to be connected to the main beam 31 for limited fixation after flipping. Through the setting of the flip cylinder 2, the main beam 31 can be driven to rotate along the rear side of the frame 11 for flipping through the extension and contraction of the flip cylinder 2.

[0038] The working principle of the crawler-type flip plow of the agricultural machine is described in detail below.

[0039] like Figures 1 to 5 As shown, the limiting plate 41 connected with the walking wheel 5 and the mounting plate 6 is clamped on the outer side of the main beam 31 and the movable beam 33 respectively, and the locking rib 43 is used to pass through the through hole 42 from the inner side of the main beam 31 and the movable beam 33, and the locking nut 45 is used to be installed from the outer thread of the limiting plate 41 to the outer thread 44, and the limiting plate 41 and the locking rib 43 are nearly locked to the outside of the main beam 31 and the movable beam 33 with the rotation of the locking nut 45. It is installed at the rear of the crawler type agricultural machine by using the frame 11, wherein the turning cylinder 2 and the amplitude modulation cylinder 36 are connected to the hydraulic system of the agricultural machine, and the movable beam 33 is driven to move along the connecting block 32 by the extension of the amplitude modulation cylinder 36. The movable beam 33 is rotated to slide along the guide rod 37. The movement of the movable beam 33 can drive the plow body 7 on the mounting plate 6 installed outside it to move, thereby adjusting the angle of the plow body 7. The position of the mounting plate 6 can be adjusted along the movable beam 33 by loosening the fixing component 4, so that the angle between the main beam 31 and the movable beam 33 changes, and the plow width of the plow body 7 can be adjusted to be wider or narrower. The main beam 31 hinged to the flip cylinder 2 can be flipped by extending and retracting the flip cylinder 2, thereby driving the walking wheel 5 and the plow body 7 to flip, and is fixed in the main beam 31 through the fixing bolts 13 on the fixing plate 12. It has a simple structure and is convenient to use.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
