[0031] Among them, the adjustment mechanism includes a No. 1 motor 4, which is fixedly installed in the middle of the right surface of the movable box 3. The other end of the output shaft of the No. 1 motor 4 is fixedly sleeved with a round shaft 5, and the outer surface of the round shaft 5 is fixedly sleeved with a No. 1 connecting rod 6 located on the right side of the movable box 3. The other end of the No. 1 connecting rod 6 is hinged with a No. 2 connecting rod 7, and the other end of the No. 2 connecting rod 7 is hinged to the bottom of the right surface of the installation box 2. The No. 1 connecting rod 6 and the No. 2 connecting rod 7 rotate to make the movable box 3 move up and down along the outer surface of the installation box 2.

[0032] When the No. 1 motor 4 is running, the circular shaft 5 will drive the No. 1 connecting rod 6 to start rotating, and the rotation of the No. 1 connecting rod 6 will drive the No. 2 connecting rod 7 to start rotating. At the same time, the rotation of the No. 1 connecting rod 6 and the No. 2 connecting rod 7 will drive the movable box 3 to move upward as a whole.

[0033] Among them, the front and rear sides of the left surface of the installation box 2 are hinged with a No. 2 movable baffle 9, and the front and rear sides of the left surface of the movable box 3 are hinged with a No. 1 movable baffle 8 located above the No. 2 movable baffle 9. The bottom end of the No. 1 movable baffle 8 passes through the No. 2 movable baffle 9 and extends to the interior of the No. 2 movable baffle 9.

[0034] Due to the design of the first movable baffle 8 and the second movable baffle 9 , when the operator pulls the first movable baffle 8 , the second movable baffle 9 will move along with the first movable baffle 8 .

[0035] Among them, the left side of the outer surface of the No. 1 movable baffle 8 is fixedly connected with a fixed plate 10, the right side of the lower surface of the fixed plate 10 is movably connected with a fixed block 11, the rear surface of the fixed block 11 is fixedly connected to the outer surface of the No. 1 movable baffle 8, and the right side of the upper surface of the fixed plate 10 is movably connected with a latch 12, the bottom end of the latch 12 passes through the fixed plate 10 and the fixed block 11 in sequence, and the outer surface of the latch 12 and the inner surfaces of the fixed plate 10 and the fixed block 11 are movably connected.

[0036] When the operator takes out the latch 12, the fixing of the first movable baffle 8 as a whole by the fixing plate 10 and the fixing block 11 will be released.

[0037] The middle parts of the left and right sides of the movable box 3 are fixedly connected with connecting shafts 13, the outer surface of the connecting shafts 13 is movably sleeved with connecting frames 14, and the middle part of the upper surface of the connecting frames 14 is fixedly connected with a lifting ring 15.

[0038] Due to the design of the connecting shaft 13 , the movable box 3 as a whole can rotate around the connecting shaft 13 as the axis.

[0039] Among them, the right end of the outer surface of the connecting shaft 13 is fixedly sleeved with a gear 16 located on the right side of the connecting frame 14, and the right side of the upper surface of the connecting frame 14 is fixedly installed with a pneumatic cylinder 17 located on the right side of the connecting frame 14. The bottom end of the pneumatic cylinder 17 passes through the connecting frame 14 and is fixedly connected with a tooth plate 18. The outer surface of the bottom end of the front side of the tooth plate 18 is meshed with the outer surface of the gear 16.

[0040] When the pneumatic cylinder 17 is running, the tooth plate 18 will start to move upward. Due to the meshing of the outer surfaces of the gear 16 and the tooth plate 18, the gear 16 will start to rotate driven by the tooth plate 18, and the rotation of the gear 16 will also drive the connecting shaft 13 and the movable box 3 as a whole to start rotating around the connecting shaft 13 as the axis.

[0041] Among them, the outer surfaces of the front and rear sides of the connecting frame 14 are movably connected to the fixing frames 19, the number of the fixing frames 19 is two, the bottom ends of the two fixing frames 19 are fixedly connected to the upper surface of the bottom plate 1, the upper surfaces of the two fixing frames 19 are fixedly connected to the top plate 20, and the outer surfaces of the two fixing frames 19 are movably connected to the outer surface of the movable box 3.

[0042] Due to the design of the fixing frame 19, the stability of the connecting frame 14 and the movable box 3 as a whole when moving up and down is guaranteed.

[0043] Among them, a support plate 21 is fixedly connected to the right side of the upper surface of the top plate 20. There are two support plates 21, and the two support plates 21 have the same size. A No. 2 motor 22 is fixedly installed on the left side of the upper surface of the top plate 20. The other end of the output shaft of the No. 2 motor 22 is fixedly sleeved with a rotating shaft 23. The right end of the rotating shaft 23 passes through the support plate 21 and extends to the right side of the support plate 21.

The other end of the sling 25 passes through the top plate 20 and passes through the lifting ring 15 and is fixedly connected to the lower surface of the top plate 20.

[0044] When the second motor 22 is running, the rotating shaft 23 will drive the winding wheel 24 to start rotating, and the rotation of the winding wheel 24 will cause the sling 25 to start winding around the outer surface of the winding wheel 24, which will cause the sling 25 to pull the entire ring 15 and the movable box 3 as a whole to start moving upward under the limit of the fixed frame 19.

[0045] The working principle and use process of this utility model:

[0046] First, the operator starts motor No. 1 4. As motor No. 1 runs, circular shaft 5 drives connecting rod No. 1 6 to start rotating. At this time, connecting rod No. 2 7 starts to rotate with the other end of connecting rod No. 1 6 as the axis driven by connecting rod No. 1 6. At this time, driven by connecting rod No. 1 6 and connecting rod No. 2 7, movable box 3 as a whole starts to move upward under the limit of the outer surface of mounting box 2. During this process, the cargo volume inside movable box 3 as a whole will gradually expand. When the volume inside movable box 3 as a whole is large enough to accommodate the materials to be transported, the operator pulls out latch 12, which allows movable baffle No. 1 8 and movable baffle No. 2 9 to rotate. At this time, the operator can put the materials into the movable box 3 as a whole.

[0047] Then the operator starts the No. 2 motor 22. The operation of the No. 2 motor 22 will cause the rotating shaft 23 and the winding wheel 24 to start rotating, and the rotation of the winding wheel 24 will cause the sling 25 to start being wound around the outer surface of the winding wheel 24. At this time, the bottom end of the sling 25 will pull the lifting ring 15, so that the lifting ring 15, the connecting frame 14 and the movable box 3 as a whole begin to move upward under the limit of the fixed frame 19. When the movable box 3 as a whole is transported to the position where it needs to be unloaded, the operator starts the pneumatic cylinder 17. The operation of the pneumatic cylinder 17 will cause the tooth plate 18 to move upward. At this time, the gear 16 will start to rotate under the meshing drive of the tooth plate 18, and the rotation of the gear 16 will cause the connecting shaft 13 and the movable box 3 as a whole to start rotating together with the connecting shaft 13 as the axis. In this process, the overall direction of the movable box 3 is changed, which causes the material inside the movable box 3 as a whole to be poured out due to the tilt of the movable box 3 as a whole, so that the operator does not need to manually take the material out of the inside of the movable box 3 as a whole, thereby reducing the labor intensity of the operator.
