[0027] A convenient mobile agricultural machinery bearing metal frame, comprising a supporting frame 1, such as Figure 1 As shown, the agricultural machinery can be placed in the middle of the support frame 1. The four corners of the lower end of the support frame 1 are welded with lower support blocks 2, and the lower support blocks 2 are welded and fixed to the support frame 1. The support of the lower support blocks 2 can achieve the fixation of the support frame 1, prevent the support frame 1 from contacting the ground, and prevent the liquid on the ground from contacting the device placed inside the support frame 1 through the support frame 1, thereby improving the safety of the device when in use;

[0028] In this embodiment, the lower ends of the four lower support blocks 2 are all provided with gaskets 3, and the two sides of the gaskets 3 are respectively connected to the two side sliding grooves inside the lower support blocks 2, such as Figure 2 and Figure 6 As shown, during the supporting process, the four positions at the lower end of the bracket are all contacted and supported by the gasket 3, and a second spring 21 for shock absorption is arranged between the gasket 3 and the lower support block 2. Through the resilience of the second spring 21, the weight of the support frame 1 and the upper object can force the gasket 3 to be stored inside the lower support block 2, thereby reducing the noise generated when the lower support block 2 and the gasket 3 are in contact;

[0029] In this embodiment, the first restricted areas 4 are arranged at the four corners of the support frame 1, and the second restricted areas 5 are arranged at the front and rear ends of the middle of the support frame 1. Figure 1 and Figure 3 As shown, an anti-slip sheet 6 is arranged inside the second restriction zone 5, and four anti-slip sheets 6 are arranged around the inside of the first restriction zone 4. When the roller 7 is switched to a horizontal position, the anti-slip sheets 6 at the positions of the first restriction zone 4 and the second restriction zone 5 protrude and adapt to the device placed inside the support frame 1, and can adapt to the housing of the device while limiting the sliding and position deviation of the device;

[0031] In this embodiment, the second threaded rods 16 are disposed at the four corners of the transmission plate 17. Figure 3 and Figure 4 As shown, the outer portion of the second threaded rod 16 cooperates with the inner thread of the transmission sheet 17, and the rotation of the second threaded rod 16 can drive and push the transmission sheet 17 to adjust the longitudinal horizontal position. The adjustment of the longitudinal horizontal position of the transmission sheet 17 can move the anti-slip sheet 6 toward the housing of the device placed inside the bracket;

[0032] In this embodiment, a connecting piece 15 is provided at the lower end of the second threaded rod 16, and the connecting piece 15 is fixedly connected to the support frame 1, a second transmission gear 14 is provided at the lower end of the connecting piece 15, and a first threaded rod 8 is welded to the lower end of the second transmission gear 14. Figure 4 and Figure 6 As shown, one end of the second threaded rod 16 facing the connecting piece 15 is rotatably connected to the inside of the connecting piece 15, and the second transmission gear 14 passes through the connecting piece 15 and is fixedly connected to the lower end of the second threaded rod 16. The rotation of the second transmission gear 14 can simultaneously drive the second threaded rod 16 and the first threaded rod 8 to rotate;

[0033] In this embodiment, the first transmission gear 13 is disposed on one side of the exterior of the second transmission gear 14, and the exterior of the first transmission gear 13 is meshedly connected with the exterior of the second transmission gear 14. Figure 4 As shown, a motor 12 for output is disposed at the lower end of the first transmission gear 13, and the output of the motor 12 can drive the second transmission gear 14 to rotate through the first transmission gear 13, and the rotation of the second transmission gear 14 can simultaneously drive the first threaded rod 8 and the second threaded rod 16 at both ends of the upper end to rotate simultaneously, and the threads on the outside of the second threaded rod 16 and the first threaded rod 8 are arranged oppositely;

[0034] In this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, a transmission ring 10 is provided at the lower end of the outside of the first threaded rod 8, and the inside of the transmission ring 10 cooperates with the external thread of the first threaded rod 8, a limiting bar 9 is provided on the other side of the second transmission gear 14, and the limiting bar 9 passes through and extends to the lower end of the transmission ring 10, the outside of the limiting bar 9 is connected to the internal sliding groove of the transmission ring 10, and the transmission ring 10 can be restricted by the limiting bar 9 to convert the rotational motion into longitudinal linear motion, a rotatable connecting frame 11 is provided on the outside of the transmission ring 10, and a rotatable roller 7 is provided at the lower end of the outside of the connecting frame 11, and the first threaded rod 8 can be rotated to push and make the roller 7 move toward the ground, and the support frame 1 and the equipment placed inside the support frame 1 can be lifted by moving toward the ground.

[0035] Working principle: when the bracket is used and the items placed inside the bracket are moved, the motor 12 is powered and outputs to the first transmission gear 13, which outputs and drives the second transmission gear 14 on one side to rotate. The second transmission gear 14 can simultaneously drive the second threaded rod 16 and the first threaded rod 8 at both ends of the upper end to rotate simultaneously. The rotation of the first threaded rod 8 will produce relative motion with the transmission ring 10. After the transmission ring 10 is restricted by the restriction bar 9, the rotational motion is converted into longitudinal linear motion. The longitudinal linear motion can be lifted by the roller 7 as a whole of the support frame 1. While the roller 7 lifts the device as a whole, the rotation of the second threaded rod 16 can produce relative motion with the transmission plate 17. After the transmission plate 17 is restricted by the movable cavity 22, the movable cavity 22 is converted from rotational motion to linear motion. The transmission plate 17 can be lifted by the support frame 1 as a whole. After the transmission of the rod 18 and the first spring 19, the anti-slip sheet 6 is pushed out of the support frame 1, and extends from the first restriction area 4 and the second restriction area 5 of the support frame 1. The extension will contact the device placed at the upper end of the support frame 1. Due to the different shapes of the devices, the continuous extension of the anti-slip sheet 6 can be limited, and the transmission sheet 17 will continue to push. The resilience of the first spring 19 does not hinder the uniform push of the transmission sheet 17. When the second transmission gear 14 rotates and causes the roller 7 and the anti-slip sheet 6 to shrink, the four corners of the lower end of the support frame 1 are contacted through the protruding gasket 3. As the roller 7 continues to shrink, it can be supported and continuously contracted by the second spring 21 until the gasket 3 is fitted and supported by the lower support block 2, thereby reducing the vibration sound of the support frame 1 when the roller 7 changes position, and avoiding damage to the upper end equipment due to shaking caused by switching.
