Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixers, in particular to a production device for double vertical concrete mixers. Background Art

[0002] Concrete is made of cement, gravel, sand and water (may contain admixtures and additives) in a certain proportion and mixed to form cement concrete. When mixing, a concrete mixer is usually used. Concrete mixers can be divided into vertical mixers and horizontal mixers.

[0003] As shown in the patent document with the announcement number CN219132767U, an existing vertical concrete mixer discloses a double-steering vertical concrete mixer, including: a mixing drum, an outer gear is installed on the outer side of the mixing drum, a driving gear is meshed and connected on the surface of the outer gear, a small motor is connected to the middle of the driving gear, one end of the small motor is connected to a fixed bracket, both ends of the fixed bracket are fixedly connected to support columns, one end of the two support columns are fixedly connected to a support plate, one end of the support plate is connected to a plurality of fixing nuts, and the fixing nuts are connected to the fixing nuts. One end of the nut is fixedly connected to one end of the bottom of the base plate, a main shaft cylindrical through hole is provided in the middle of the mixing drum, a mixing main shaft is installed in the middle of the main shaft cylindrical through hole, a mixing blade is installed at one end of the mixing main shaft, a main shaft nut is connected to the top of one end of the mixing main shaft, a slide rail is installed at the bottom of the mixing drum, a circular slide rail is installed inside the base plate, the top of the circular slide rail is rotatably connected to the circular slide rail, a reserved hole is provided in the middle of the base plate, the other end of the mixing main shaft is connected to the main motor through the reserved hole, and one end of the main motor is connected to the motor support frame.

[0004] Although the mixer can increase the mixing power by rotating the mixing blades and the mixing drum in opposite directions at the same time, in actual use, due to the fixed height of the mixing blades, the mixing blades can only be mixed at the same height of the mixing drum. When the raw materials mostly submerge the mixing blades, the raw materials at the upper part of the mixing drum are not easy to be mixed by the mixing blades, which not only takes more mixing time and affects the mixing efficiency, but also easily causes uneven mixing of the raw materials.

[0005] Therefore, we propose a double vertical concrete mixer production device to solve the above problems. Utility Model Content

The bottom end of the screw 8 is connected to the stirring rod 5, and a servo motor 9 is installed at the top of the screw 8. The servo motor 9 is used to drive the screw 8 to rotate. When the screw 8 rotates, it interacts with the crossbeam 7 and then screws upward or downward, driving the stirring rod 5 to rotate and rise and fall for more thorough stirring. Considering that the movement of the screw 8 will drive the servo motor 9 to move, a limit cover 10 is fixed on the crossbeam 7 to cover the outside of the servo motor 9, and the outer wall of the servo motor 9 is connected to a limit rod 11, which passes through the outside of the limit cover 10 and is slidably connected to the limit cover 10, so that the servo motor 9 slides inside the limit cover 10, and the sliding action between the limit rod 11 and the limit cover 10 can prevent the servo motor 9 from axial rotation during movement.

[0028] See also Figure 3In order to save energy consumption of the entire equipment, the gear 4 and the stirring rod 5 are driven by the same servo motor 9. A connecting rod 12 is coaxially fixed on the gear 4, and the connecting rod 12 passes through the crossbeam 7 and the limit rod 11, and the crossbeam 7 and the limit rod 11 will not limit the rotation of the connecting rod 12.

A driving wheel 14 is coaxially fixed on the outside of the connection between the servo motor 9 and the screw 8, so that the servo motor 9 can drive the driving wheel 14 to rotate, and a synchronous belt 15 is sleeved between the driving wheel 14 and the driven wheel 13 for transmission, so that the driving wheel 14 drives the driven wheel 13 to rotate through the synchronous belt 15.

[0029] See also Figure 1-3 In order to prevent the concrete raw materials from adhering to the surface of the screw rod 8 during mixing and affecting the threaded connection between the screw rod 8 and the cross beam 7, the length of the screw rod 8 is set to be not less than the length of the stirring rod 5, and the length of the stirring rod 5 is not less than the depth of the mixing drum 2, so that the screw rod 8 will not extend into the mixing drum 2, preventing the screw rod 8 from contacting the raw materials.

[0030] See also Figure 3 In order to ensure stable transmission between the driven wheel 13 and the connecting rod 12, the connecting rod 12 is set to adopt a square rod structure, and a square groove matching the connecting rod 12 is opened inside the driven wheel 13, so that the limit rod 11 can drive the driven wheel 13 to rise and slide relative to the connecting rod 12, and at the same time prevent the driven wheel 13 and the connecting rod 12 from slipping and being unable to rotate together.

[0031] See also Figure 1-3 In order to improve the stability of the connecting rod 12 when driving the gear 4 to rotate, a plurality of stabilizing seats 16 are installed between the connecting rod 12 and the bracket 6, and the connecting rod 12 and the stabilizing seats 16 are connected through bearings.

[0032] See also Figure 4-5 In order to facilitate the later disassembly, cleaning or maintenance of the device, a protruding rod 61 is provided at the top of the bracket 6, and the protruding rod 61 passes through the positioning hole on the beam 7. One end of the protruding rod 61 passing through the beam 7 is threadedly connected with a screw sleeve 62. The screw sleeve 62 locks the beam 7, and anti-slip pads 63 are clamped between the bracket 6 and the beam 7 and between the beam 7 and the screw sleeve 62. The anti-slip pad 63 is sleeved on the protruding rod 61, thereby improving the locking effect of the screw sleeve 62 and preventing loosening. At the same time, multiple sets of bolts 81 and nuts 82 are set between the stirring rod 5 and the screw 8 for connection, which is convenient for separating the stirring rod 5 and the screw 8 in the later stage.
