[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. Embodiment

[0020] A pressing mechanism of a rotary tillage, fertilizing, ridging and pressing multi-functional machine, as Figures 1 - 3 shown, includes a mounting arm 1, a floating swing arm 2, an elastic top support mechanism and a pressing wheel 3. A connecting portion is provided at the front end of the mounting arm 1. The mounting arm 1 can be connected to the frame of the ridging machine through the connecting portion. The floating swing arm 2 is arranged at the rear end of the mounting arm 1. The floating swing arm 2 is connected to the mounting arm 1 and rotates relative to the mounting arm 1. A pressing wheel 3 is arranged on the floating swing arm 2. The pressing wheel 3 rotates relative to the floating swing arm 2. The rotation axis of the pressing wheel 3 is parallel to the rotation axis of the floating swing arm 2 relative to the mounting arm 1. The swinging of the floating swing arm 2 relative to the mounting arm 1 can drive the pressing wheel 3 to perform height adjustment relative to the mounting arm 1.

[0021] An elastic top support mechanism is provided on the mounting arm 1. The elastic top support part of the elastic top support mechanism is connected to the floating swing arm 2. The elastic top support mechanism presses down the floating swing arm 2 so that the pressing wheel 3 can press on the ridge. The elastic top support mechanism has elasticity. When the pressing wheel 3 presses on sundries such as stones, it can lift. When the pressing wheel 3 crosses sundries such as stones, the elastic top support mechanism continues to press down the floating swing arm 2 so that the pressing wheel 3 presses on the ridge. A pressing ring is provided on the pressing wheel 3, and each pressing ring is distributed along the axial direction of the pressing wheel 3.

[0022] In some embodiments, in order to facilitate fertilization into the ridge, a fertilizer hook mounting position 10 is provided on the mounting arm 1. The fertilizer hook mounting position 10 includes a plurality of holes suitable for connecting the fertilizer hook. The fertilizer hook mounting position 10 is in front of the floating swing arm 2. The fertilizer hook mounting position 10 is used to mount the fertilizer hook of the fertilization mechanism. After the ridger forms the ridge, the fertilization mechanism uses the fertilizer hook to fertilize into the ridge, and then the pressing wheel 3 presses the ridge again.

[0023] To facilitate the installation of the elastic top support mechanism and the elastic top support of the floating swing arm 2, the mounting arm 1 protrudes upward at the rear side of the connection with the floating swing arm 2, and the elastic top support mechanism is arranged in the protruding area of the mounting arm 1.

[0024] As a specific example of the elastic top support mechanism, the elastic top support mechanism is a spring 4. The top end of the spring 4 is connected to the mounting arm 1, and the bottom end of the spring 4 is a floating support part and is connected to the floating swing arm 2. The spring 4 presses down the floating swing arm 2 to press the pressing wheel 3 on the floating swing arm 2 onto the ridge.

[0025] As another specific example of the elastic top support mechanism, the elastic top support mechanism includes a spring 4, a top support rod 5 and a lower connecting plate 6. The lower connecting plate 6 is arranged on the floating swing arm 2. A lower through hole is provided on the lower connecting plate 6. The lower through hole is preferably an elongated hole. The top support rod 5 is connected to the mounting arm 1 and rotates relative to the mounting arm 1. The top support rod 5 passes through the lower through hole and its bottom end is located below the lower connecting plate 6. The spring 4 is sleeved on the top support rod 5 and is located between the mounting arm 1 and the lower connecting plate 6. The top support rod 5 being arranged inside the spring 4 can prevent the spring 4 from bending and deforming, and limit the swinging direction of the floating swing arm 2 relative to the mounting arm 1.

[0026] As a further example of the elastic supporting mechanism, in addition to the spring 4, the supporting rod 5 and the lower connecting plate 6, the elastic supporting mechanism also includes an upper connecting member 7, which is connected to the mounting arm 1 and rotates relative to the mounting arm 1, and the rotation axis of the upper connecting member 7 is parallel to the rotation axis of the pressing wheel 3. An upper through hole is provided on the upper connecting member 7, and the supporting rod 5 passes through the upper through hole and the lower through hole. The supporting rod 5 is a screw rod, and nuts are provided on the supporting rod 5 above the upper connecting member 7 and below the lower connecting plate 6. The spring 4 is sleeved on the supporting rod 5 and is located between the upper connecting member 7 and the lower connecting plate 6. Rotating the upper nut can drive the floating swing arm 2 to rotate upward or downward relative to the mounting arm 1 by driving the screw to lift or lower, thereby driving the pressing wheel 3 to lift or lower, and then adjusting the minimum pressing height of the pressing wheel 3. According to the ridging height of the ridging machine, the height of the pressing wheel 3 can be adjusted in a targeted manner to avoid the pressing wheel 3 being too low to damage the ridges, or to avoid the pressing wheel 3 being too high to have no effect on the pressing of the ridges. To facilitate the rotation of the upper nut, an adjusting hand wheel 8 is provided above the upper connecting member 7, and the adjusting hand wheel 8 is connected to the nut above the upper connecting member 7, and the upper nut is more easily adjusted by adjusting the hand wheel 8.

[0027] In some embodiments, a wheel frame 9 is provided on the floating swing arm 2, and the wheel axle of the pressure wheel 3 is connected to the wheel frame 9 and the pressure wheel 3 can rotate relative to the wheel frame 9. The wheel frame 9 is preferably a door-shaped frame. In some further embodiments, the wheel frame 9 is also provided with a door-shaped reinforcement structure. The wheel frame 9 is provided with a connecting arm, which is connected to the floating swing arm 2 and rotates relative to the floating swing arm 2. The rotation of the connecting arm relative to the floating swing arm 2 can also adjust the height of the pressure wheel 3. A fastener is also provided between the connecting arm and the floating swing arm 2. When the connecting arm rotates to a suitable state relative to the floating swing arm 2, the connecting arm and the floating swing arm 2 can be locked by the fastener, and at this time, the wheel frame 9 as a whole cannot rotate relative to the floating swing arm 2.

[0028] Specifically, the floating swing arm 2 is provided with a plurality of connection holes, each of which is distributed circumferentially around the rotation center of the wheel frame 9 relative to the floating swing arm 2. An inner support tube is provided on the connection arm, and a fastener is passed through the inner support tube and the fastener cooperates with the connection hole, thereby locking the connection arm and the floating swing arm 2, so that the wheel frame 9 as a whole cannot rotate relative to the floating swing arm 2. The fastener is a pin shaft or a similar pin shaft structure, and when the fastener passes through the connection hole and the inner support tube at the same time and the connection arm cannot rotate relative to the floating swing arm 2, the wheel frame 9 is locked.
