When the traction frame 41 moves forward along with the tractor after being connected with the agricultural cultivation equipment, the rolling support assembly 44 plays a role of rolling support for the traction frame 41, the support strength and linkage of the traction frame 41 are ensured, when the traction frame 41 moves forward along with the tractor after being connected with the agricultural cultivation equipment, the rollers 449 at the bottom of the rolling support assembly 44 are in contact with the ground, when the traction frame 41 shakes up and down, the rollers 449 are in contact with the ground, so that the traction frame 41 plays a role of elastic support, because the agricultural cultivation equipment has larger gravity, after the agricultural cultivation equipment is connected with the traction frame 41, if the rolling support assembly 44 is not supported, the connecting arm of the agricultural cultivation equipment and the traction frame 41 are difficult to be in the same horizontal plane, moreover, the end part of the traction frame 41 and the frame 1 of the tractor are also in a hinged state, and under the gravity of the traction frame 41 and the gravity of the agricultural cultivation equipment, the traction frame 41 is difficult to horizontally pull the agricultural cultivation equipment, therefore, the rolling support assembly 44 is installed at the bottom of the traction frame 41;

the height of the roller 449 at the bottom of the rolling support assembly 44 can be adjusted, and the height of the roller 449 can be adjusted in two ways, the first is: the second handle 446 is rotated by a hand, the second handle 446 drives the second locking screw rod 445 to rotate, after the end part of the second locking screw rod 445 is separated from the second thread bushing 444, the second mounting plate 441 and the second buckle plate 442 are in a loosening state, after the supporting sleeve 443 is adjusted in a lifting mode, the height of the roller 449 at the bottom of the supporting sleeve can also be adjusted correspondingly, the mode is mainly used for roughly adjusting the height of the roller 449, after the roller 449 is adjusted roughly, the second handle 446 is rotated reversely, the second handle 446 drives the second locking screw rod 445 to rotate reversely, after the second locking screw rod 445 is reconnected with the second thread bushing 444, the second mounting plate is arranged on the supporting sleeve 444, and after the second locking screw rod 445 is reconnected with the second thread bushing 444, the second locking screw rod 445 is driven to rotate reversely by the second handle 446

441 and the second pinch plate 442 are in a clasping state, at this time, the second pinch plate 442 can clasp the fixed support sleeve 443 to prevent the support sleeve 443 from loosening, and at this time, the approximate height of the roller 449 can be fixed.

The second height adjustment of the roller 449 is: after the approximate height of the roller 449 is adjusted, a person rotates the rocking handle 410 forward, the rocking handle 410 drives the supporting rod 448 to rotate at the end of the supporting sleeve 443, when the supporting rod 448 rotates forward, the supporting rod 448 extends out relative to the supporting sleeve 443, at the moment, the roller 449 at the end of the supporting rod 448 descends gradually, the contact gap and the contact pressure between the roller 449 and the ground are adjustable, the longer the extending length of the supporting rod 448 is, the greater the extrusion force between the roller 449 and the ground is, and the stronger the elastic supporting force is applied to the bottom of the traction frame 41 in the forward moving process;

similarly, the hand rotates the rocking handle 410 in the opposite direction, the rocking handle 410 drives the supporting rod 448 to rotate at the end of the supporting sleeve 443, when the supporting rod 448 rotates in the opposite direction, the supporting rod 448 contracts relative to the supporting sleeve 443, at the moment, the roller 449 at the end of the supporting rod 448 ascends gradually, the contact gap and the contact pressure between the roller 449 and the ground are adjustable, the retracting length of the supporting rod 448 is longer, the extrusion force between the roller 449 and the ground is smaller, and the elastic supporting force applied to the bottom of the traction frame 41 is weaker in the advancing process.

It should be noted that roller 449 may be positioned close to the ground during relatively flat farming and that the distance between roller 449 and the ground may be suitably increased during relatively rough farming.

In summary, after the suspension shock absorption mechanism 2 is adopted in the device, the suspension shock absorption mechanism 2 is installed between the axle housing 21 and the rack 1 through the first connecting arm 24 and the third connecting arm 26 which are hinged with each other, the rotation performance between the first connecting arm 24 and the third connecting arm 26 is ensured while the axle housing 21 is suspended on the rack 1, meanwhile, the second connecting arm 25 and the fourth connecting arm 27 which are hinged with each other are installed between the axle housing 21 and the rack 1, the second connecting arm 25 and the fourth connecting arm 27 play a role of suspending the axle housing 21, in order to reduce the swing amplitude of the third connecting arm 26 and the fourth connecting arm 27, the first damper 28 is installed between the third connecting arm 26 and the axle housing 21, the second damper 29 is installed between the fourth connecting arm 27 and the axle housing 21, the first damper 28 and the second damper 29 have elastic supporting and shock absorption functions, the third connecting arm 26 and the fourth connecting arm 27 are ensured to have swing elasticity, the third connecting arm 26 and the fourth connecting arm 27 also ensure that the third connecting arm have different damping seats 212, the damping seat 213 plays a role of improving the whole damping function of the damping mechanism 213 of the damping mechanism on the axle housing 21, and the damping mechanism 213, and the damping mechanism are suitable for improving the whole damping mechanism of the suspension shock absorption mechanism, and the suspension mechanism, and the damping mechanism is suitable for improving the suspension mechanism for the suspension of the suspension device for the suspension of the suspension device for the suspension of the suspension bridge type;
