[0032] Embodiment one:

[0033] When the automatic lifting mixer is working, the hopper filled with materials needs to be placed in the mixer frame and finally clamped with the automatic lifting of the frame. The mixer will hold the hopper through the rotating frame, rotate along the mixing rotating shaft, and a reliable automatic locking mechanism is needed to fix the hopper cover on the hopper during rotation to meet the mixing requirements.

[0034] As shown in Figures 1 to 7 The embodiment provides a hopper cover locking structure of a mixer, which comprises a hopper 1, a hopper cover 2, and at least two locking assemblies 3 uniformly arranged along the outer periphery of the hopper cover 2. The upper end of the hopper 1 is provided with a first fixed protruding ring 100, the upper end of the hopper cover 2 is provided with a second fixed protruding ring 200, and the hopper cover 2 is arranged above the hopper 1 through a lifting mechanism.

The sealing ring 90 can improve the sealing effect between the hopper cover 2 and the hopper 1, prevent material leakage during mixing, and ensure the mixing quality. Secondly, the inverted trapezoidal design makes the sealing ring 90 more stable in the groove and not easy to fall off, and at the same time, it can better compress the sealing ring 90 to form a tighter seal between the hopper cover 2 and the hopper 1.

[0036] Preferably, the locking assembly 3 is three and is arranged at intervals of 120°, which ensures that the force on the hopper cover during locking is uniform, avoids deviation, and improves the locking stability.

[0037] Secondly, the locking assembly 3 comprises a fixed plate 30, a locking cylinder 31, a locking seat 32 and a locking block 33, the locking cylinder 31 is connected with the hopper cover 2 through the fixed plate 30, the locking cylinder 31 comprises a driving shaft 310, the locking seat 32 is connected with the driving shaft 310, the locking seat 32 is L-shaped and comprises a vertical plate part 320 and a horizontal plate part 321, the locking block 33 is detachably connected with the horizontal plate part 321, and the locking block 33 is provided with a locking port 34 facing the first fixed convex ring 100 and the second fixed convex ring 200, the locking port 34 comprises an upper inclined surface 340 and a lower inclined surface 341, and the upper inclined surface 340 and the lower inclined surface 341 are close to the side close to the locking seat 32. Through the above arrangement, after the hopper is lifted into position, the sensor can transmit a signal to the control system, and the originally protruding driving shaft 310 is pulled back to complete locking. During the locking process, the locking seat 32 and the locking block 33 have a transverse displacement, and the locking block 33 itself has an inclined surface, which guides the locking block 33 to lock the hopper cover 2 and the hopper 1 during the locking process, and the locking is completed.

[0038] In the embodiment of the present disclosure, the upper side of the first fixed convex ring 100 is provided with a first inclined groove 101 matched with the upper inclined surface 340, the first inclined groove 101 can be embedded with the locking block 33, and the lower side of the second fixed convex ring 200 is provided with a second inclined groove 201 matched with the lower inclined surface 341, the second inclined groove 201 can be embedded with the locking block 33, and the design of the first inclined groove 101 and the second inclined groove 201 enables the locking block 33 to be more firmly fixed between the hopper 1 and the hopper cover 2, thereby enhancing the locking effect and preventing the hopper cover 2 from loosening during the mixing process.

[0039] In the embodiment of the present disclosure, two guide shafts 4 are symmetrically arranged on the locking seat 32 with the output shaft as the center, the fixed plate 30 is provided with two through holes 5 through which the guide shafts 4 pass, an axle sleeve 6 is arranged between the through hole 5 and the driving shaft 310, an enlarged hole part 50 with a larger diameter than the through hole 5 is arranged at the outer end of the through hole 5, the axle sleeve 6 comprises a convex ring part 60 matched with the enlarged hole part 50, a fixing ring 7 is arranged on the outer end face of the fixed plate 30, the fixing ring 7 abuts against the convex ring part 60, which ensures the smooth movement of the guide shaft 4 in the through hole 5, and through the precise matching of the axle sleeve 6 and the enlarged hole part 50, the stability and sealing performance of the overall structure are enhanced, thereby improving the smoothness of the movement of the locking block 33. Secondly, the convex ring part 60 abuts between the enlarged hole part 50 and the fixing ring 7, which further fixes the axle sleeve 6 and prevents it from moving, thereby improving the reliability and service life of the equipment.

[0040] Optionally, the transition between the hole expansion part 50 and the through hole 5 is provided with a bevel 8, and the bevel and the shaft sleeve 6 form a deformation cavity 80, so that the presence of the deformation cavity 80 allows the shaft sleeve 6 to have a certain deformation allowance in the transition area, thereby improving the stability and sealing of the connection, and avoiding damage to the shaft sleeve 6.

[0041] In the embodiments of the present disclosure, an adjusting block 35 is arranged between the locking seat 32 and the locking block 33, the adjusting block 35 is provided with a threaded hole, the locking block 33 is provided with a connecting hole matched with the threaded hole, and the locking block 33 and the adjusting block 35 are fixed by connecting the connecting hole and the threaded hole through a bolt, so that the locking block 33 and the adjusting block 35 are convenient to disassemble and assemble, a plurality of first adjusting holes are vertically and spaced apart on the adjusting block 35, and a plurality of second adjusting holes are vertically and spaced apart on the locking seat 32, so that the height of the locking block 33 can be flexibly adjusted, and more specifications of the hopper 1 and the hopper cover 2 can be adapted.

[0042] Optionally, the bottom plate 10 is further included, and the two fixing plates 30 are arranged on the bottom plate 10 to form a fixing frame, and the fixing frame is adjustably arranged along the moving direction of the driving shaft 310, so that the locking distance of the locking block 33 can be flexibly adjusted, and more specifications of the hopper 1 and the hopper cover 2 can be adapted.

[0043] The included angle between the upper inclined surface 340 and the lower inclined surface 341 is 30°-45°, and preferably 35°, which can adapt to more specifications of the hopper 1 and the hopper cover 2 and has a better locking effect.

[0044] The length of the upper inclined surface 340 is greater than the length of the lower inclined surface 341, and since the length of the upper inclined surface 340 is greater, the stiffness and deformation resistance of the entire structure are enhanced, a larger load and impact are adapted, and the impact resistance of the hopper cover 2 in the mixing operation can be improved.
