[0025] See also Figure 1 - Figure 5 As shown, this embodiment is a quick-release mixing assembly for a concrete mixer, including a mixing drum 1 and a gantry 2. The upper surface of the mixing drum 1 is detachably connected with a mounting frame 3, and the upper surface of the mounting frame 3 is fixedly connected with a gantry 9. The upper surface of the mounting frame 3 is located inside the gantry 9 and a motor 12 is fixedly installed. The mounting frame 3 is provided with a quick-release mechanism, which includes a pulley 4 arranged on the gantry 9. A winch 5 for lifting the gantry 2 is fixedly installed on one side of the top wall of the gantry 2. A connecting sleeve 20 is fixedly connected to the lower surface of the mounting frame 3. A mixing shaft 15 is inserted at the bottom of the connecting sleeve 20. A slot 22 is provided on the outer contour of the connecting sleeve 20. Two symmetrically arranged connecting columns 21 are fixedly connected to the outer contour of the mixing shaft 15 near the top. The connecting column 21 is screwed with the slot 22. An annular groove 16 is provided on the outer contour of the mixing shaft 15. Two symmetrically arranged arc-shaped pieces 17 are engaged in the annular groove 16, and one of the arc-shaped pieces 17 is fixedly connected to the connecting arm 13.

[0026] The card slot 22 is set in an inverted L shape. The mounting frame 3 and the connecting frame 7, and the mounting frame 3 and the mixing drum 1 are detachably connected by bolts. The bolts between the mounting frame 3 and the mixing drum 1 are removed to separate the mixing drum 1 from the mounting frame 3. When the winch 5 located on the gantry 2 is started, the mounting frame 3 can be pulled to move in the vertical direction as a whole, so that the mixing shaft 15 at the bottom of the mounting frame 3 and the mixing rod 14 on the mixing shaft 15 can be disassembled and replaced. The mixing shaft 15 is rotated to separate the connecting column 21 fixedly connected to the mixing shaft 15 from the connecting column 21, which reduces maintenance costs and improves the overall availability of the equipment. Damaged or worn parts can be quickly replaced. The quick disassembly design allows more frequent inspection and replacement of parts, which helps preventive maintenance, thereby extending the overall life of the equipment. The fast and simple maintenance process reduces maintenance costs and manual operation risks, and improves the overall efficiency and safety of the equipment.

[0027] The annular grooves 16 are arranged at vertical intervals, and the two arc-shaped pieces 17 are arc-shaped pieces that fit the annular grooves 16. The end of the connecting arm 13 away from the stirring shaft 15 is fixedly connected to the stirring rod 14, and the bottom end of each stirring rod 14 extends toward the bottom of the mixing drum 1; the annular grooves 16 are arranged at intervals, and the connecting arms 13 are arranged in a ring array on the stirring shaft 15 for interval distribution, which is convenient for disassembly and separation of individual connecting arms 13 and stirring rods 14. Grooves for bolt insertion are opened on the surfaces of the two arc-shaped pieces 17 and are fixedly connected with bolts.

[0028] Two pulleys 4 are provided and are symmetrically arranged. A connecting piece 11 is fixedly connected to both ends of the pulley 4 on the upper surface of the gantry 9. The pulley 4 is rotatably connected to the two connecting pieces 11; the connecting piece 11 is rotatably connected to the pulley 4 through a pin shaft. By setting two pulleys 4 and cooperating with the winch 5 to lift it, it can be lifted stably.

[0029] A rope 6 is sleeved on the two pulleys 4, one end of the rope 6 is fixedly connected to one side of the top of the gantry 2, and the other end of the rope 6 is sleeved on the winding roller of the winch 5; when the winch 5 is started, the winding roller of the winch 5 rotates to wind up the rope 6, which can lift the gantry 2 9, thereby moving the mounting frame 3 fixedly connected to the gantry 2 9 as a whole, separating the mounting frame 3 from the mixing drum 1, and replacing the mixing shaft 15 and the connecting arm 13 on the mixing shaft 15.

[0030] Both ends of the mounting frame 3 close to the inner wall of the slide groove 8 are fixedly connected with connecting frames 7, and slide grooves 8 are opened on both sides of the inner wall of the gantry frame 2. The connecting frame 7 extends into the slide groove 8 and is rotatably connected with rollers 10; by setting the rollers 10 to contact the inner wall of the slide groove 8, the rollers 10 can ensure the stability of the gantry frame 2 9 in the vertical direction, reduce friction and enable it to rise stably.

[0031] Embodiment 2:

[0032] This embodiment is used to solve the problem of splashed concrete, cement and other debris entering the card slot 22 and causing blockage.

[0033] See also Figure 1 , Figure 5 As shown, a quick-release mixing assembly for a concrete mixer in this embodiment includes two sleeves 18 sleeved on the outer contour of a connecting sleeve 20, the two sleeves 18 are fixedly connected by bolts, and the bottom ends of the two sleeves 18 are fixedly connected to a bottom plate 19, which fits the outer wall of the mixing shaft 15.

[0034] By providing the bottom film 19 and the sleeve 18, when the concrete is stirred, it is prevented that the splashed concrete cement and other debris enters the slot 22 and causes blockage, making it inconvenient to subsequently rotate the stirring shaft 15, so that the stirring shaft 15 is separated from the connecting sleeve 20. By providing the bottom film 19, it is prevented that the splashed concrete cement enters the slot 22 from the bottom of the connecting sleeve 20.

[0035] Combining Embodiment 1 with Embodiment 2

[0036] By setting a quick release mechanism and moving the mounting frame 3 in the vertical direction, the disassembly and replacement process of the stirring shaft 15 and the stirring rod 14 is further simplified. By rotating the stirring shaft 15, the connecting column 21 can be easily separated from the card slot 22 on the connecting sleeve 20, which simplifies the maintenance process of the concrete mixer, reduces the maintenance cost, and improves the overall availability of the equipment. By setting a quick release mechanism, damaged or worn parts can be quickly replaced, and the maintenance process is fast and simple, which reduces the maintenance cost and manual operation risk, and improves the overall efficiency and safety of the equipment. The design of the bottom film 19 and the sheath 18 keeps the equipment clean and stable by preventing the entry of concrete debris, simplifies the maintenance process, and improves the efficiency and reliability of the equipment.

[0037] like Figure 1 - Figure 5 As shown, the working process and principle of the utility model are as follows:

[0038] Step 1: Remove the bolts between the mounting frame 3 and the mixing drum 1 to separate the mixing drum 1 from the mounting frame 3, start the winch 5 on the gantry 1 2, rotate the winding roller of the winch 5 to wind up the rope 6, and lift the gantry 2 9, so that the mounting frame 3 fixedly connected to the gantry 2 9 is moved as a whole, and the mounting frame 3 is separated from the mixing drum 1, and the mixing shaft 15 and the connecting arm 13 and the mixing rod 14 on the mixing shaft 15 are replaced, and the mixing shaft 15 is rotated to separate the connecting column 21 fixedly connected to the mixing shaft 15 from the connecting column 21, and the replacement of the mixing shaft 15 is completed;

[0039] Step 2: Use bolts to tightly fit the two stirring shafts 15, seal the connecting column 21 at the connection between the stirring shaft 15 and the connecting sleeve 20, and seal the bottom side of the connecting sleeve 20 by setting a bottom film 19 to prevent splashed concrete, cement and other debris from entering the slot 22 and causing blockage, making it inconvenient to rotate the stirring shaft 15 subsequently, so as to separate the stirring shaft 15 from the connecting sleeve 20.
