[0025] like Figure 1-9 As shown in the figure, the contour-following press described in this embodiment includes a towing frame 1 and contour-following press mechanisms symmetrically arranged on the left and right sides of the towing frame 1. The towing frame 1 can be towed behind a tractor. Its structure and connection relationship with the tractor are existing technologies in the field and will not be described in detail here. The contour-following press mechanism includes a first crossbeam 2 and a second crossbeam 3. Press rollers 4 are respectively arranged on the first crossbeam 2 and the second crossbeam 3. A connection and drive device is provided between one end of the first crossbeam 2 and the towing frame 1, and the other end of the first crossbeam 2 and the second crossbeam 3.

[0026] The connection and drive device includes a hinge frame 5, a floating connection frame 6, a first swing frame 7, a second swing frame 8, a first hydraulic cylinder 9, and a second hydraulic cylinder 10. The hinge frame 5 includes two frames arranged symmetrically front and rear. One end of the frame is hinged to the first crossbeam 2, and the other end is hinged to the second crossbeam 3. The two frames are fixedly connected by a longitudinal beam 11. The longitudinal beam 11 is provided with a first crossbeam damping block 12 and a second crossbeam damping block 13. When the conformal pressing mechanism is folded up and stored, the first crossbeam damping block 12 and the second crossbeam damping block 13 contact the first crossbeam 2 and the second crossbeam 3 respectively to avoid collision. The first crossbeam damping block 12 and the second crossbeam damping block 13 are both rubber blocks.

[0027] A floating connecting frame 6 is fixed on a hinged frame 5, and the floating connecting frame 6 is equipped with a first shaft 14, a second shaft 15, a first rod 16, a second rod 17, and a third rod 18. A first swing frame 7 is narrower and is hinged to the floating connecting frame 6 and the second swing frame 8 via the first shaft 14. The second swing frame 8 is wider and is directly hinged to the floating connecting frame 6 via the second shaft 15. A third shaft 19 is also provided on the first swing frame 7, and the piston rod end of the first hydraulic cylinder 9 is hinged to the third shaft 19.

[0028] To facilitate the folding and storage of the contour-following pressing mechanism and reduce the overall width of the pressing unit during transportation, the first crossbeam 2 is designed to swing horizontally in a controlled manner. Specifically, the end of the first crossbeam 2 is hinged to the traction frame 1 via a vertical shaft. The traction frame 1 is equipped with a first crossbeam drive cylinder 22, the cylinder body of which is hinged to the traction frame 1, and the piston rod end is hinged to the first crossbeam 2. During transportation, the contour-following pressing mechanism can swing back to a position parallel to the traction frame 1 and maintain this position, thereby significantly reducing the overall width of the pressing unit and facilitating road passage. The traction frame 1 is also equipped with a first crossbeam auxiliary drive cylinder 23. The first crossbeam 2 is hinged to the traction frame 1 via a vertical shaft, on which a swing arm 24 is fixed. The cylinder body of 23 is hinged to the traction frame 1, and the piston rod end is hinged to the swing arm 24. The first crossbeam auxiliary drive cylinder 23 can assist the first crossbeam 2 in swinging backward.

Specifically, the first cylinder 9 and the second cylinder 10 are both retracted. Under the action of the hinge frame 5, the floating connecting frame 6, the first swing frame 7, and the second swing frame 8, the second crossbeam 3 can be folded upward to a state parallel to the first crossbeam 2. When it is folded up, the second cylinder 10 first retracts completely. At this time, the second crossbeam 3 is in a 90° vertical upward posture. The first cylinder 9 then retracts completely, and the second crossbeam 3 can be folded upward to a state parallel to the first crossbeam 2.

[0029] A pressing roller 4 is also installed on the traction frame 1. The pressing roller 4 on the traction frame 1 cooperates with the pressing roller 4 in the contour pressing mechanism to achieve full coverage of the pressing device's forward trajectory. A ground wheel frame 25 and a ground wheel frame drive cylinder 26 are also installed on the first crossbeam 2. One end of the ground wheel frame 25 is hinged to the first crossbeam 2, and the other end is equipped with a ground wheel 27. The cylinder body of the ground wheel frame drive cylinder 26 is hinged to the first crossbeam 2, and the piston rod end is hinged to the ground wheel frame 25. When the pressing device is transported, the ground wheel frame 25 is lowered, and the ground wheel 27 contacts the road surface, supporting the contour pressing mechanism while facilitating movement.

[0030] The working principle of this embodiment is as follows:

[0031] This embodiment is towed behind a tractor, folded during transport, and unfolded for field work, with five working states: First: The first crossbeam 2 and the second crossbeam 3 are on the same horizontal plane, suitable for flat ground; Second: Pulling out the positioning pin 21 controls the operation of the first cylinder 9 and the second cylinder 10, causing the second crossbeam 3 to fall parallel. In this state, the first crossbeam 2 and the second crossbeam 3 are both horizontal but not on the same horizontal plane, suitable for ground with steps; Third: Pulling out the positioning pin 21 controls the operation of the first cylinder 9 and the second cylinder 10, causing the second crossbeam 3 to rise parallel. In this state, the first crossbeam 2 and the second crossbeam 3 are both horizontal but not on the same horizontal plane, also suitable for... The fourth method involves pulling out the positioning pin 21 to control the first hydraulic cylinder 9 and the second hydraulic cylinder 10, causing the second crossbeam 3 to tilt upwards. At this time, the second crossbeam 3 is placed at an angle, which is suitable for use on sloping plots. The fifth method involves pulling out the positioning pin 21 to control the first hydraulic cylinder 9 and the second hydraulic cylinder 10, causing the second crossbeam 3 to tilt downwards. At this time, the second crossbeam 3 is placed at an angle, which is also suitable for use on sloping plots. Compared with the prior art, the contour pressing mechanism in this embodiment can achieve independent adjustment of different segments and angles, so that the pressing rollers at each point can fit well with the ground and achieve the purpose of following the contour as the ground changes. It is particularly suitable for use on plots with uneven terrain and potholes.
