Description

Technical Field

[0001] This utility model relates to the field of sand mixer technology, and in particular to a fixed structure for a sand mixer drive motor. Background Technology

[0002] In the traditional drive system of a sand mixer, a combination of a drive wheel and a belt is usually used, with a motor driving the mixing roller to rotate, thereby achieving the mixing operation of materials in the mixing drum. However, this drive method requires control of the belt tension to ensure transmission efficiency and stability. Therefore, traditional sand mixers often include a tensioning wheel structure specifically for adjusting belt tension. However, such a setting not only makes the sand mixer structure more complex and bulky, but also increases production costs and affects the overall compactness and economy of the equipment. Utility Model Content

[0010] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0011] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0012] according to Figures 1-4As shown, a fixed structure for a drive motor of a sand mixer is characterized by: a sand mixer body 1, a top crossbeam 2 on the sand mixer body 1, a sand mixing roller 3 and a motor mounting base 4 on the top crossbeam 2, the sand mixing roller 3 being mounted in the sand mixer body 1 via the top crossbeam 2, the motor mounting base 4 being mounted on one side of the sand mixer body 1 via the top crossbeam 2, and a drive motor 5 being mounted on the motor mounting base 4; a large pulley 31 is mounted on the upper end of the sand mixing roller 3, and a small pulley 51 is mounted on the movable end of the drive motor 5; V-belts 6 are mounted on the large pulley 31 and the small pulley 51; the motor mounting base 4 includes a motor base plate 41, the... The drive motor 5 is mounted on the motor base plate 41. The top crossbeam 2 has a large hinge seat 21 and a small hinge seat 22 on one side, which are respectively located at both ends of the side of the top crossbeam 2. One end of the motor base plate 41 is hinged to the large hinge seat 21, and the other end of the motor base plate 41 is provided with a hinge bolt 42 and a set screw 44. The hole of the hinge bolt 42 is hinged to the small hinge seat 22. A pair of nut sleeves 43 are also provided on the hinge bolt 42. The nut sleeves 43 are located on both sides of the motor base plate 41. A support 23 is provided on the top crossbeam 2 at the position corresponding to the set screw 44.

[0013] The set screw 44 is positioned near the outer side. A threaded sleeve 45 is fixedly provided on the motor base plate 41 at the position where the set screw 44 passes through, so that the motor base plate 41 can be rotated when the set screw 44 rotates. The position on the motor base plate 41 where the hinge bolt 42 passes through is provided as a through hole structure, so that the motor base plate 41 can move along the hinge bolt 42 when it is rotated.

[0014] The set screw 44 has a round head at one end and abuts against the support 23. The tail end is provided with a rotary joint 46, which is a polygonal cylindrical structure that allows the set screw 43 to be rotated using a wrench or other tools.

[0015] During use, first loosen the nut sleeve 43 on the hinge bolt 42 to disengage it from both sides of the motor base plate 41. Flip the motor base plate 41 outward and adjust the nut sleeve 43 on the outer side of the motor base plate 41. Flip the motor base plate 41 inward and adjust the nut sleeve 4 on the inner side of the motor base plate 41. Adjusting the nut sleeve 4 can also initially limit the adjustment range. Next, by rotating the set screw 43, it extends from the bottom of the motor base plate 41. Since the end of the set screw 43 presses against the support 23, it can lift one side of the motor base plate 41, allowing the motor base plate 41 to rotate around its hinge point with the large hinge seat 21. This also allows for control. The rotation angle of the motor base plate 41 is determined to control the position of the drive motor, thereby adjusting the tension of the V-belt 6. After the tension is adjusted to the ideal state, the nut sleeves 43 on both sides are rotated again to re-clamp the motor base plate 41 and fix the adjusted position. The end of the set screw 43 is set with a round head structure, which can adapt to the deflection of the set screw 43 during the adjustment process and ensure that its end is always pressed against the support 23. At the same time, the hinge setting between the hinge bolt 42 and the small hinge seat 22 allows the hinge bolt 42 to rotate flexibly during the adjustment process to adapt to the rotation action of the motor base plate 41.

[0016] This design is ingenious. By setting the motor mounting base 4, the rotation angle of the motor base plate 41 can be easily adjusted, thereby controlling the tension of the V-belt 6, ensuring the stability and efficiency of the transmission. The control structure is integrated on the motor base plate 41, reducing the need for tensioning pulleys and related structural settings, effectively improving the space utilization of the equipment, making the overall equipment more streamlined, and reducing equipment costs.

[0017] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
