Description

Technical Field

[0001] This utility model relates to the field of work technology, and in particular to a concrete mixing device. Background Technology

[0002] Concrete is a concrete mixing device made by mixing cement as a binder, sand and stone as aggregates, and water in a certain proportion. Chinese Utility Model Patent, authorized publication number "CN222079665U", discloses a concrete mixing device, including a base, a discharge assembly on the top of the base, an outer cylinder inside the discharge assembly, a replacement assembly between the inner and outer sides of the outer cylinder, and a threaded post fixedly installed at the bottom of a mounting block. The threaded post is inserted into a corresponding insertion hole, and a nut is screwed onto the outer side of the threaded post below the fixing block. This utility model relates to the field of concrete mixing technology. When replacing the mixing drum, this concrete mixing device first moves the mixing rod out of the mixing drum and tilts the outer cylinder at a certain angle. Then, the nut is removed, contacting the fixing block and the mounting block. The mixing drum is then removed from the outer cylinder by moving the mounting block upwards. After removal, a new mixing drum is placed in and fixed, thus completing the fixing of the mixing drum and solving the problem that if the mixing drum breaks, the entire mixing device becomes unusable.

[0003] The above technical solution uses the up-and-down movement of the moving block to drive the top cover up and down, which in turn drives the mixing rod up and down. By moving the mixing rod into the mixing drum, the top cover covers the top of the mixing drum, and the mixing motor is started to drive the mixing rod to rotate, the mixing rod mixes the concrete inside. However, the above technical solution still has certain drawbacks. For example, although the equipment uses the mixing motor to drive the mixing rod to rotate and mix the concrete inside, when the mixing rod needs maintenance and repair after long-term use, workers need to use special tools to disassemble the entire mixing assembly before disassembling the mixing rod. This increases the workload of workers and reduces the efficiency of maintenance and repair of the mixing rod. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a concrete mixing device that can solve the problem that the device drives the mixing rod to rotate through the mixing motor, and mixes the internal concrete through the mixing rod. However, when the mixing rod needs to be maintained and repaired after long-term use, the workers need to use special tools to disassemble the entire mixing assembly and then disassemble the mixing rod. This increases the workload of the workers and reduces the efficiency of maintenance and repair of the mixing rod.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a concrete mixing device, comprising a base, a sliding column, a support column, and a mixing tank, wherein a limit component is provided on the sliding column;

The upper outer wall of the connecting seat 13 is slidably connected to the inside of the connecting seat groove 17. The ends of the two limiting blocks 15 near the first limiting block grooves 14 slidably extend into the inside of the connecting seat groove 17 and are respectively connected to the opposite side. The first limiting block groove 14 is slidably connected inside. The ends of the two pull rods 19 near the limiting block 15 are slidably extended into the interior of the second limiting block groove 16 and are respectively fixedly connected to the end of the corresponding limiting block 15. The outer walls of the upper and lower fixing blocks of the two protective shells 10 are threaded with rotating threaded rods 11. The outer walls of the upper and lower fixing blocks of the two pull rods 19 are provided with fixing block grooves 2. The interiors of the upper and lower fixing blocks of the two protective shells 10 are slidably connected with fixing blocks 18. The interiors of the upper and lower fixing blocks of the two protective shells 10 are respectively connected to the interiors of the corresponding second limiting block grooves 16. The ends of the four fixing blocks 18 near the fixing block grooves 2 are slidably extended into the interior of the second limiting block grooves 16 and are respectively slidably connected to the interiors of the corresponding fixing block grooves 2. The outer walls of the four conical blocks at the upper end of the connecting seat 13 are slidably connected to the interiors of the four conical block grooves on the inner wall of the connecting seat groove 17.

[0033] The support column 4 is fixedly installed on the outer wall of the rear end of the base 1. One end of the sliding column 3 is sleeved on the outer wall of the support column 4. The support column 4 is hollow. Two T-shaped block grooves 9 are opened on the upper surface of the base 1. The outer walls of the two T-shaped blocks at the lower end of the mixing tank 6 are slidably connected to the interior of the corresponding T-shaped block grooves 9. The stirring shaft 7 is positioned opposite to the mixing tank 6. A threaded rod 12 is rotatably connected inside the support column 4. One end of the sliding column 3 is threadedly connected to the outer wall of the threaded rod 12. A first motor 5 is fixedly connected to the upper outer wall of the support column 4. The output end of the first motor 5 extends rotatably into the interior of the support column 4 and is fixedly connected to one end of the threaded rod 12. The outer walls of the tapered blocks on both sides of one end of the sliding column 3 are slidably connected to the interior of the tapered block grooves on both sides of the support column 4. The bolts threadedly connected to the outer walls of the two T-shaped blocks on the mixing tank 6 are threaded to the interior of the T-shaped block grooves 9 and are threadedly connected to the grooves opened inside the T-shaped block grooves 9.

[0034] Furthermore, when using this device, during the concrete mixing process, the mixing tank 6 is first slidably connected to the T-shaped slots 9 on the upper surface of the base 1 via two T-shaped blocks on the lower base, and the T-shaped blocks are fixed in the T-shaped slots 9 with bolts to ensure the stable installation of the mixing tank 6.

Since one end of the sliding column 3 is threadedly connected to the outer wall of the threaded rod 12, and the tapered blocks on both sides of one end of the sliding column 3 slide in cooperation with the tapered slots on the support column 4, the rotation of the threaded rod 12 causes the sliding column 3 to move up and down along the support column 4, thereby adjusting the height of the mixing shaft 7 so that it enters a suitable mixing position inside the mixing tank 6. Then, after the mixing shaft 7 is adjusted to the appropriate position, the mixing process continues... Start the second motor 8 to drive the mixing shaft 7 to rotate and mix the concrete raw materials in the mixing tank 6. During the mixing process, the sliding column 3 can move up and down appropriately under the drive of the first motor 5, so that the mixing shaft 7 can mix concrete raw materials of different heights and improve the mixing effect. After the mixing is completed, loosen the fixing bolts of the mixing tank 6 and slide the mixing tank 6 off the base 1 for unloading or replacement. When disassembling the mixing shaft 7, rotate the rotating threaded rods 11 on the upper and lower sides of the protective shell 10 to drive the fixing block 18 to disengage from the fixing block groove 2 on the pull rod 19 and release the position of the limiting block 15. Then pull the pull rod 19 to drive the limiting block 15 to disengage from the inside of the first limiting block groove 14. Then pull the mixing shaft 7 to remove it.

[0035] By rotating the threaded rods 11 on the upper and lower sides of the protective shell 10 in the limiting assembly, the fixing block 18 is disengaged from the fixing block groove 2 on the pull rod 19, and the position of the limiting block 15 is released. Then, the pull rod 19 is pulled to disengage the limiting block 15 from the inside of the first limiting block groove 14. Then, the stirring shaft 7 can be removed by pulling it. This method of disassembling the stirring shaft 7 is simple and quick, avoiding the need for workers to use special tools to disassemble the stirring shaft 7. It effectively reduces the workload of workers and improves the maintenance and repair efficiency of the stirring shaft 7.
