[0030] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0031] like Figures 1 to 7 As shown, an embodiment of the utility model provides a horizontal adjustment mechanism, including a support frame 1, a supporting assembly 2, a rotating plate 3 and a correcting assembly 4, wherein the rotating plate 3 can be rotatably mounted on the support frame 1, and the supporting assembly 2 is arranged on the rotating plate 3;

[0032] The supporting assembly 2 has a bearing surface 21, and the correction assembly 4 is disposed on the supporting frame 1. The correction assembly 4 is used to drive the rotating plate 3 to rotate around the supporting frame 1 to adjust the inclination angle of the bearing surface 21 of the supporting assembly 2 relative to the horizontal plane. In this embodiment, the silo to be transported is placed on the bearing surface 21, and the bearing surface 21 is a horizontal surface when it is unloaded or working normally; or when it is unloaded or working normally, the bearing surface 21 of the supporting assembly 2 has a horizontal part, and the inclination angle between the horizontal part of the bearing surface 21 and the horizontal plane is detected to determine whether the supporting assembly 2 needs to be rotated.

[0033] In one embodiment, the horizontal adjustment mechanism further includes a detection component 5, the support component 2 has a mounting surface arranged opposite to the bearing surface 21, the detection component 5 is arranged on the mounting surface, and the detection component 5 is used to detect the inclination angle of the mounting surface relative to the horizontal plane. In this embodiment, the bearing surface 21 and the mounting surface of the support component 2 are parallel surfaces. During normal operation, the bearing surface 21 is a horizontal surface, and the angle between the bearing surface 21 and the horizontal plane is 0°. When the angle signal detected by the detection component 5 is greater than 0°, the correction component 4 drives the support component 2 to rotate clockwise until the angle between the bearing surface 21 fed back by the detection component 5 and the horizontal plane is 0°, and the correction component 4 stops driving, so that the bearing surface 21 of the support component 2 is in a horizontal state. When the angle signal detected by the detection component 5 is less than 0°, the correction component 4 drives the support component 2 to rotate counterclockwise until the angle between the bearing surface 21 fed back by the detection component 5 and the horizontal plane is 0°, and the correction component 4 stops driving, so that the bearing surface 21 of the support component 2 is in a horizontal state.

[0034] In one embodiment, the correction component 4 includes a driving member 41 and a transmission shaft 42. The support frame 1 is provided with a guide hole 11. The transmission shaft 42 is passed through the guide hole 11. One end of the transmission shaft 42 is connected to the driving member 41, and the other end abuts against the rotating plate 3. The driving member 41 is installed on the support frame 1, and is used to drive the transmission shaft 42 to reciprocate along the axial direction of the guide hole 11.

[0035] In one embodiment, the driving member 41 includes a driving motor 411, a driving wheel 412 and a driven wheel 413. The housing of the driving motor 411 is mounted on the support frame 1, the driving wheel 412 is fixed at the output end of the driving motor 411, and the driven wheel 413 is meshed with the driving wheel 412.

[0036] The guide hole is a threaded hole, and the transmission shaft 42 is threadedly connected in the guide hole 11. The center of the driven wheel 413 has an accommodating channel 4131. Along the rotation direction of the driven wheel 413, the accommodating channel 4131 has a first side wall 4132 and a second side wall 4133 opposite to each other. The transmission shaft 42 is inserted between the first side wall 4132 and the second side wall 4133, and the transmission shaft 42 can move along the axial direction of the driven wheel 413. In this embodiment, the driving wheel 412 and the driven wheel 413 are both spur gears. The connection method between the driving wheel 412 and the output shaft of the driving motor 411 is the prior art and will not be described here. The end of the transmission shaft 42 connected to the driven wheel 413 is a smooth end, and the periphery of the end of the transmission shaft 42 connected to the guide hole 11 is provided with a threaded structure. The transmission shaft 42 can be integrally formed, with a convex portion provided at the smooth end; it can also be formed by a transmission shaft body and a flat key. In this embodiment, the transmission shaft 42 is formed by a transmission shaft body and a flat key. The accommodating channel 4131 includes a through hole for accommodating the transmission shaft 42 and an open groove for accommodating the flat key. The through hole is connected to the open groove, and the two ends of the open groove are respectively a first side wall 4132 and a second side wall 4133. A groove for installing the flat key is provided at the smooth end of the transmission shaft 42, and the flat key is installed in the groove. When the transmission shaft 42 is installed in the through hole, the flat key is inserted into the open groove, and along the rotation direction of the driven wheel 413, the two opposite sides of the flat key are respectively in contact with the first side wall 4132 and the second side wall 4133. The circumferential positioning of the transmission shaft 42 is achieved through the first side wall 4132 and the second side wall 4133, so that the driven wheel 413 can drive the transmission shaft 42 to rotate. At the same time, along the axial direction of the driven wheel 413, the transmission shaft 42 is slidably connected in the driven wheel 413. When the transmission shaft 42 rotates in the guide hole 11, the transmission shaft 42 can move along the axial direction of the driven wheel 413. In this embodiment, when there are more PCBs, the silo 6 is heavier, and the angle signal fed back by the detection component 5 is greater than 0°, the control center commands the drive motor 411 to rotate, and the drive motor 411 transmits torque to the transmission shaft 42. Because the support frame 1 is fixed, the transmission shaft 42 moves relative to the support frame 1, so that the end of the transmission shaft 42 can extend further out of the guide hole 11. At the same time, because the transmission shaft 42 abuts against the rotating plate 3, the rotating plate 3 rotates around the support frame 1, thereby driving the rotating plate 3 to rotate until the angle signal fed back by the detection component 5 is 0°, and the drive motor 411 stops rotating. When the number of PCB boards in the silo 6 gradually decreases, the deformation of the support component 2 (lifting arm) gradually eases, and when the angle signal fed back by the detection component 5 is less than 0°, the control center commands the drive motor 411 to rotate in the opposite direction, and the end of the transmission shaft 42 slowly retracts. Under the action of its own gravity, the support component 2 slowly rotates counterclockwise around the support frame 1 until the angle signal fed back by the detection component 5 is 0°, and the drive motor 411 stops rotating. In this way, the support component 2 is always in a horizontal state.

Different from the above embodiment, in this embodiment, no threaded structure is provided in the guide hole 11, instead, the sleeve body 71 provided with a threaded hole is installed in the guide hole 11, so that the transmission shaft 42 is threadedly connected in the sleeve body 71, and the transmission shaft 42 and the sleeve body 71 form a screw nut structure. During installation, the sleeve body 71 and the mounting seat 72 of the guide sleeve 7 are installed on the support frame 1 by screws. In this embodiment, the inner holes of the guide hole 11 and the sleeve body 71 are both through-hole structures, and the transmission shaft 42 passes through the guide hole 11 and the inner hole of the sleeve body 71 to connect with the rotating plate 3.

According to the principle of lever, it is most labor-saving to set the guide hole 11 at the bottom of the support frame 1, but according to actual needs, setting the guide hole 11 in the middle of the support frame 1 or at the upper position of the support frame 1 is also within the protection scope of this embodiment.

When the angle signal detected by the detection component 5 is less than 0°, the piston rod of the hydraulic cylinder retracts, driving the supporting component 2 to rotate counterclockwise, until the angle between the bearing surface 21 fed back by the detection component 5 and the horizontal plane is 0°, and the hydraulic cylinder stops driving, so that the bearing surface 21 of the supporting component 2 is in a horizontal state.
