DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, 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.

[0020] Embodiment 1

[0021] See also Figure 1-Figure 4 , a flip plow with a buffer mechanism shown in the figure comprises a protective shell 1, a movable groove 11 is arranged on both upper and lower sides of the protective shell 1, a buffer component 3 is arranged inside the movable groove 11, and a lifting component 6 is connected to the outer side of the protective shell 1;

[0022] The lifting assembly 6 is arranged inside the connection frame 2. A turntable 7 is fixedly connected to one side of the connection frame 2. A rotary cylinder 71 is connected to one end of the turntable 7. The rotary cylinder 71 is arranged on a connection frame 72.

[0023] The lifting assembly 6 includes a motor 63, the output end of the motor 63 is connected to the threaded rod 62, a connecting block 64 is spirally connected to the threaded rod 62, a sliding rod 61 is arranged in parallel on both sides of the threaded rod 62, a connecting block 64 is slidably connected to the sliding rod 61, a reinforcing rib 641 is arranged on the connecting block 64, and the connecting block 64 is fixed to one side of the protective shell 1;

[0024] The buffer assembly 3 includes a connecting plate 31, one side of the connecting plate 31 is connected to a bracket 5 via a connecting bolt, and a plowshare 4 is fixedly mounted on the bracket 5;

[0025] The other two ends of the connecting plate 31 are fixedly connected with fixed blocks 32, a second slide bar 35 is connected between the fixed blocks 32, and a slider 36 is slidably connected to both ends of the second slide bar 35, and one side of a single slider 36 is connected to the adjacent fixed block 32 through a spring 1 37;

[0026] A connecting rod 38 is rotatably connected to the slider 36, and the slider 36 is connected to a connecting arm 39 through the connecting rod 38. The connecting arm 39 is fixed on the inner wall of the movable groove 11. The connecting rod 38 is rotatably connected to the connecting arm 39. The fixed block 32 is connected to the inner wall of the movable groove 11 through a damping rod 33. The damping rod 33 is arranged in the middle of the spring 34, and the two ends of the spring 34 are respectively connected to the fixed block 32 and the inner wall of the movable groove 11.

[0027] In this solution, during the tillage process, it is easy to generate bumps due to the influence of different soil conditions. The buffer assembly 3 is used to buffer the bumps. The bumps and shaking easily push the connecting plate 31 to drive the fixed block 32 to move in the moving groove 11. During the movement, the fixed block 32 squeezes the spring 2 34 and the damping rod 33. The spring 2 34 is elastically deformed by the squeezing and generates an elastic restoring force in the opposite direction of the external force, thereby achieving a buffering and shock absorbing effect, helping to absorb and slow down the impact force. The damping rod 33 limits the rebound or extension speed of the spring 2 34 through the internal damping mechanism to prevent the spring 2 34 from rapidly expanding and contracting and causing unstable movement.

[0028] During the movement of the connecting plate 31, the distance between the slider 36 and the inner wall of the moving groove 11 becomes closer, so that the angle between the connecting rod 38 and the connecting arm 39 between the slider 36 and the connecting arm 39 becomes smaller, so that the connecting rod 38 can push the slider 36 to move on the slide bar 2 35 toward the adjacent fixed block 32, and then can squeeze the spring 1 37, and use the spring 1 37 to further improve the buffering effect, reduce the impact of bumps, and make the turning of the soil more stable. At the same time, when facing hard objects, it can absorb the impact force generated by the collision, and reduce the impact of the impact force on the internal structure of the tractor. The buffer component 3 is arranged in the protective shell 1, and the protective shell 1 can be used to protect the buffer component 3;

[0029] The lifting assembly 6 connected to the outside of the protective shell 1 can control the turning depth of the plowshare 4, so as to meet the requirements of different turning depths. During the adjustment process of the lifting assembly 6, the motor 63 is used to drive the threaded rod 62 to rotate, and the threaded rod 62 is spirally connected to the connecting block 64, so that the threaded rod 62 can control the protective shell 1 to rise and fall along the slide bar 61 through the connecting block 64, thereby adjusting the height of the plowshare 4 and controlling the turning depth. The reinforcing rib 641 provided on the connecting block 64 can strengthen the connection between the connecting block 64 and the protective shell 1;

[0030] The connecting frame 2 is installed on the tractor through the connecting frame 72, and the rotating cylinder 71 on the connecting frame 72 is used to control the turntable 7 to drive the connecting frame 2 to rotate, so that the protective shell 1 can be controlled to rotate through the lifting component 6, so that the upper and lower plowshares 4 in the protective shell 1 can be turned over. When the tractor drives the flip plow to move in the opposite direction, the same-direction turning operation can be achieved to ensure that the turned soil is gathered on the same side, avoiding the space occupied by turning the soil on both sides, which is conducive to close-range turning. At the same time, the plowshare 4 and the bracket 5 are connected to the connecting plate 31 through connecting bolts. When the plowshare 4 is damaged, it can be disassembled by the connecting bolts to replace a single damaged plowshare 4.
