DETAILED DESCRIPTION

[0017] In order to make the technical means for realizing the utility model, creative features, objectives and effects easy to understand, the utility model is further explained below in conjunction with specific diagrams. In the description of the utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an integral connection or a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be internal communication between two components.

[0018] Example

[0019] like Figure 1-Figure 5The drum turning mechanism for a vertical sand mill shown in the figure comprises a bottom plate 1, a fixed bracket 2 is installed on the bottom plate 1, the fixed bracket 2 is in a "U"-shaped structure as a whole, and the two sides of the fixed bracket 2 are connected to the flap rocker 4 and one end of the second rocker 19 through the bracket torsion joint 3; the flap rocker 4 is installed on both sides of the flap 5, wherein the grinding drum is connected to the bearing box 8 and then installed on the flap 5; in order to install the bearing box 8 and other structures, a mounting hole 6 is opened on the flap 5, and a sliding adjustment hole 7 is provided on the side of the mounting hole 6, and an avoidance hole 14 is opened on the top surface of the fixed bracket 2, wherein the position of the bearing box 8 can be fine-tuned through the sliding adjustment hole 7, and the mounting hole 6 and the avoidance hole 14 can avoid the bottom structure of the bearing box 8;

[0020] In order to realize the rotation of the flap 5, the flap rocker 4 is connected to one end of the first rocker 10 through the rocker torque joint 9, and the other end of the first rocker 10 is connected to one end of the second rocker 19 through the rocker torque joint 9. An anti-reverse rotation plate 11 is installed between the second rocker 19 and the first rocker 10. The anti-reverse rotation plate 11 can prevent the second rocker 19 and the first rocker 10 from rotating in the opposite direction; wherein, the bracket torsion joint 3 and the rocker torsion joint 9 have the same structure and both include a connecting rod 12. Joint bearings 13 are installed at both ends of the connecting rod 12. Two rockers that need to move relative to each other are connected by two joint bearings 13 in surface contact, so that multi-stage rotation can be realized through the cooperation between multiple rockers.

[0021] In actual use, in order to fix the bracket, a fixing hole 15 is opened at one end, and a buffer component 16 is installed inside the fixing hole 15. The top of the buffer component 16 is located in the limiting hole 20 on the flap 5. The buffer component 16 can be used to slow down when the flap 5 is placed to avoid the flap 5 from hitting the fixed bracket 2 and causing damage when it is lowered; the buffer component 16 is not limited to one structure. In this example, the buffer component 16 includes a base 17, and a buffer spring is installed inside the base 17. The buffer spring is connected to a buffer head 18, and the buffer head 18 can move up and down along the base 17. The position of the buffer head 18 corresponds to the limiting hole 20. When the flap 5 is lowered, the buffer head 18 is located inside the limiting hole 20 to ensure that the flap 5 is in a horizontal position under normal conditions.

[0022] The process flow and working principle of the utility model are as follows: in normal working state, the flap 5 is fixed to the fixed bracket 2 by screws, the vertical sand mill is partially disassembled, the grinding cylinder is carefully and gently moved forward and downward with both hands, and the grinding cylinder is tilted down under the cooperation of the flap rocker 4, the second rocker 19 and the first rocker 10, and a material receiving box is placed below the tilting direction of the grinding cylinder in advance, and when the grinding cylinder tilts downward to the maximum extent, it reaches the preset position. At this time, the grinding zirconium beads in the grinding cylinder will flow out partly under the action of gravity and downward force, and the remaining zirconium beads can be wetted and cleaned with a pointed curved mouth squeeze pot. After the grinding cylinder is processed, it is reset with both hands, and when it is placed, the buffer assembly 16 plays a buffering role to avoid collision. After the flap 5 is in a horizontal position, the front and rear positioning pins are inserted, and the fixing screws between the flap 5 and the fixed bracket 2 are installed.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
