[0038] In the embodiment, the bearing 12 is a thrust bearing.

[0039] The locking device of the embodiment is initially in a state where the piston rod of the cylinder 7 is extended and the rotating block 2 is parallel to the mixing truck. When locking is needed, the piston rod of the cylinder 7 is retracted, the connecting plate 9 connected to the piston rod is retracted in the horizontal direction, the other end of the connecting plate 9 is rotated counterclockwise, the screw shaft 10 is also rotated counterclockwise due to the key connection between the connecting plate 9 and the screw shaft 10, the screw shaft 10 drives the rotating block 2 to rotate counterclockwise, the rotating block 2 is changed from the parallel state to the vertical state with the mixing truck 17, and is attached to the mixing truck 17 to lock the mixing truck 17.

[0040] Embodiment 2. An automatic overturning mixer composed of the locking device described in embodiment 1, as shown in Figures 6-7 At least two locking devices 19 are arranged on the mixing barrel 1.

[0041] The locking device in the embodiment is provided with two, which are symmetrically arranged on both sides of the mixing barrel 1 and can lock the mixing truck. The seat plate A3 and the seat plate B4 arranged at intervals with the seat plate A3 are welded on the mixing barrel 1.

[0042] Its working principle is as follows: After the mixing cart 17 is filled with various materials that have been mixed in the required proportions, it is pushed into the lower part of the automatic tilting mixer. The elevator lifts the mixing cart 17 to the edge of the mixing drum. There are rubber pads between the edge of the mixing drum and the edge of the mixing cart 17. The compression between the edges forms a seal, which is then locked by the locking device. The tilting device then tilts the mixing cart 17. The locking device reduces the impact on the elevator during tilting and improves the service life of the elevator. After the cart is tilted 180 degrees, the mixing system starts to mix the materials. After mixing for 3 minutes, the tilting system causes the mixing cart 17 to tilt 210 degrees in the opposite direction, pauses for 10 seconds, and then rotates 210 degrees in the forward direction so that the cart is vertically upward. After mixing for another 3 minutes, it rotates 180 degrees in the opposite direction. The materials are then mixed. The tightening device is released, the elevator falls, and the mixing cart 17 is separated from the mixing drum. It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0043] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
