The flip plate 5 can support the trolley 2 as a whole. A pressure plate 6 is fixedly connected to the lower side of the flip plate 5. The pressure plate 6 is used to increase the contact area between the bottom of the flip plate 5 and the ground, thereby increasing its stability. The lower side of the pressure plate 6 is made of rubber, which has elasticity and anti-slip ability. A drive mechanism is provided on the upper side of the trolley 2.

[0023] refer to Figure 3The drive mechanism includes a dual-axis motor 7 fixedly connected to the upper side of the trolley 2. The output shafts on the front and rear sides of the dual-axis motor 7 are fixedly connected to worm gears 8. A worm wheel 9 meshes with the lower side of the worm gear 8. The inner wall of the worm wheel 9 is fixedly connected to the surface of the round rod 4. The end of the worm gear 8 away from the dual-axis motor 7 is movably connected to a support plate 10 through a bearing. The support plate 10 is fixedly connected to the bottom of the trolley 2. A handle 12 height adjustment mechanism is provided on the right side of the upper side of the trolley 2.

[0024] As a technical optimization of this utility model, by setting a drive mechanism, it can be ensured that the flip plate 5 remains stable after supporting the trolley 2 and will not easily return to its original position due to external force; at the same time, the structure is compact, occupies little space, is easy to install on the upper side of the trolley 2, and the power transmission is stable and reliable.

[0025] refer to Figure 4 The height adjustment mechanism of the handle 12 includes a fixed cylinder 11 fixedly connected to the upper side of the trolley 2. The inner wall of the fixed cylinder 11 is slidably connected to the handle 12. The inner side of the handle 12 is fixedly connected to the lifting plate 13. The inner wall of the lifting plate 13 is threadedly connected to the screw 14. The lower end of the screw 14 is movably connected to the upper side of the trolley 2 through a bearing.

[0026] As a technical optimization of this utility model, by setting a height adjustment mechanism for the handle 12, the height of the handle 12 can be flexibly adjusted to meet the usage needs of operators of different heights and improve the comfort and convenience of operation.

[0027] refer to Figure 4 A rotating disk 15 is fixedly connected to the upper end of the screw 14. The rotating disk 15 is used to facilitate the hand rotation of the screw 14.

[0028] As a technical optimization of this utility model, by setting a rotating disk 15, a convenient hand support point is provided for the operator, making it easier and less strenuous to rotate the screw 14, reducing the difficulty of adjusting the height of the handle 12, and improving work efficiency.

[0029] refer to Figure 4 The surface of the screw 14 is movably connected to the stabilizer 16 via a bearing, and the lower side of the stabilizer 16 is fixedly connected to the upper side of the trolley 2.

[0030] As a technical optimization of this utility model, by setting a stabilizing frame 16, which is fixed on the upper side of the trolley 2, the stabilizing frame 16 can support and stabilize the screw 14, prevent the screw 14 from deviating or shaking during rotation, ensure the smoothness and accuracy of the threaded transmission, and extend the service life of the equipment.

[0032] As a technical optimization of this utility model, by setting the limiting plate 17, the overturning plate 5 is effectively prevented from overturning and damaging the equipment or affecting normal use, thus protecting the equipment and ensuring the normal operation of the support and stability mechanism.

[0033] The working principle and usage process of this utility model are as follows: In use, the dual-axis motor 7 of the drive mechanism is started, and its output shaft drives the worm 8 to rotate. Since the worm 8 meshes with the worm wheel 9, the worm wheel 9 rotates accordingly. Because the worm wheel 9 is fixed to the surface of the round rod 4, the round rod 4 also rotates, thereby causing the flipping plates 5 on the left and right sides of the outer side of the round rod 4 to flip, so that the flipping plates 5 support the entire trolley 2. The pressure plate 6 on the lower side of the flipping plate 5 increases the contact area with the ground, improving stability. When it is necessary to adjust the height of the handle 12, the rotating disk 15 in the handle 12 height adjustment mechanism is rotated, driving the screw 14 to rotate. The lifting plate 13, which is threadedly connected to the screw 14, moves up and down, thereby causing the handle 12, which is fixed on the lifting plate 13, to slide within the fixed cylinder 11, realizing the height adjustment of the handle 12, thus accommodating operators of different heights. The limiting plate 17 prevents the flipping plate 5 from over-flipping, and the stabilizing frame 16 enhances the stability of the screw 14 rotation. This avoids the poor stability caused by unstable support of the intelligent fan 1 in small grain silos, and makes it easy to use.

[0034] In summary, when this utility model is used, under the action of the supporting and stabilizing mechanism and the driving mechanism, it can support the intelligent fan 1 for small grain silos, ensuring its ease of movement while increasing its operational stability. This avoids the poor stability caused by unstable support of the intelligent fan 1 for small grain silos, giving it the advantage of being easy to use.
