It is only for the convenience of describing these implementation manners and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.

[0036] Please refer to Figures 1 to 7As shown in the figure, a sand box turret mechanism 100 of the present utility model, the turret mechanism 100 includes a rotating column 1, a rotating drive cylinder 2, a drive cylinder mounting seat 3 and a support frame 4; the rotating column 1 is arranged vertically in the support frame 4, and the upper end of the rotating column 1 is rotatably connected to the upper part of the support frame 4, and the lower end of the rotating column 1 is rotatably connected to the lower part of the support frame 4, so that the rotating column 1 can rotate relative to the support frame 4; the drive cylinder mounting seat 3 is arranged at the lower part of the support frame 4, and the drive cylinder mounting seat 3 is located in front of or behind the rotating column 1; the rotating drive cylinder 2 is rotatably connected to the drive cylinder mounting seat 3, and the telescopic end of the rotating drive cylinder 2 faces the rotating column 1 and is hinged to any side of the rotating column 1. When the present utility model is specifically used, sand boxes 200 are arranged on both sides of the rotating column 1. When it is necessary to drive the rotating column 1 to rotate 180° by the rotating drive cylinder 2, the telescopic end of the rotating drive cylinder 2 will first retract backward and drive the rotating column 1 to rotate. When the rotating drive cylinder 2 pulls the rotating column 1 to rotate 90°, the rotating column 1 will continue to rotate under the action of inertia. At the same time, the telescopic end of the rotating drive cylinder 2 will extend forward and drive the rotating column 1 to rotate to the 180° position, thereby driving the sand box to also rotate 180°.

[0037] The present utility model designs the turret mechanism 100 to include a rotating column 1 rotatably arranged vertically in the support frame 4, a drive cylinder mounting seat 3 arranged at the lower part of the support frame 4 and a rotating drive cylinder 2 rotatably connected to the drive cylinder mounting seat 3, so that the drive cylinder mounting seat 3 is located in front of or behind the rotating column 1, and at the same time, the telescopic end of the rotating drive cylinder 2 faces the rotating column 1 and is hinged to any side of the rotating column 1; so that during specific work, the rotating column 1 can be driven to rotate 180° by the rotating drive cylinder 2, thereby reliably driving the sand box to also rotate 180°, enabling the two sets of sand boxes 200 to alternately achieve continuous production, which helps to improve production efficiency.

[0038] In some embodiments of the present utility model, the rotating column 1 includes a main shaft body 11 and a first square outer frame body 12; the upper end of the main shaft body 11 is rotatably connected to the upper part of the support frame 4 through a first bearing assembly 13, and the lower end of the main shaft body 11 is rotatably connected to the lower part of the support frame 4 through a second bearing assembly 14, so that the main shaft body 11 can rotate relative to the support frame 4; the first square outer frame body 12 is fixedly sleeved outside the main shaft body 11 along the vertical direction. The present utility model designs the rotating column 1 to include the main shaft body 11 and the first square outer frame body 12 fixedly sleeved outside the main shaft body 11, so that exactly 4 planes can be formed in the front, back, left and right of the rotating column 1, which can not only protect the main shaft body 11, but also make the whole rotating column 1 more beautiful and will not affect the setting of the sand box 200.

[0039] More specifically, the rotating column 1 further includes a second square outer frame body 15.

[0043] Furthermore, a tipping cylinder hinge seat 162 is arranged on the front or back surface of the third square outer frame body 16, and a third hinge shaft hole 1621 is formed on the tipping cylinder hinge seat 162. During specific use, a tipping drive oil cylinder 400 needs to be arranged between the tipping cylinder hinge seat 162 and the swing arm 300, so as to drive the swing arm 300 to drive the sand box 200 to swing and turn by using the tipping drive oil cylinder 400.

The bottom plate 31 is fixed on the support frame 4; shaft body mounting holes 34 are formed in the middle positions on the upper surface of the bottom plate 31 and the lower surface of the top plate 32. The upper and lower ends of the rotating shaft body 21 are rotatably mounted in the shaft body mounting holes 34 through first bearings 35, so that the rotary driving cylinder 2 can realize the rotation function under the action of the rotating shaft body 21 during the working process.

[0046] In some embodiments of the present invention, in order to better meet the actual support requirements, the support frame 4 includes an upper frame body 41, a lower frame body 42 and support columns 43 connecting the upper frame body 41 and the lower frame body 42; the first bearing assembly 13 is connected to the upper frame body 41, and the second bearing assembly 14 is connected to the lower frame body 42.
