DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 2 As shown, a concrete mixing drive mechanism replaces the existing "belt drive" or "single gear drive" to drive the concrete mixing drum 1 to rotate and mix the concrete raw materials in the concrete mixing drum 1, thereby reducing the concrete mixing quality problems caused by "jamming". The concrete mixing drum 1 is driven and controlled by the drive mechanism to rotate and mix the concrete raw materials in the concrete mixing drum 1. Thus, the improved drive mechanism can control the rotation of the concrete mixing drum 1 and fully mix the concrete raw materials in the concrete mixing drum 1.

[0027] In the embodiment, the drive mechanism includes a first drive gear 21, a second drive gear 22, and a connecting gear 23. A drum gear 11 is provided on the outer wall of the concrete mixing drum 1. The first drive gear 21 is rotatably connected to one end of the first curved support 2 via a rotating shaft, the second drive gear 22 is rotatably connected to the other end of the first curved support 2 via a rotating shaft, and the connecting gear 23 is rotatably connected to the middle portion of the first curved support 2 via a rotating shaft. The concrete mixing drum 1 is placed on the first curved support 2, and the drum gear 11 is rotatably engaged with the first drive gear 21, the second drive gear 22, and the connecting gear 23, respectively. Furthermore, a second curved support 3 is provided at the end of the concrete mixing drum 1 away from the first curved support 2. The end of the concrete mixing drum 1 closer to the second curved support 3 is movably placed on the second curved support 3. Both the first curved support 2 and the second curved support 3 are movably mounted on a support base 4, which is designed to be mounted and fixed at the designed position of the mixer. To drive the concrete mixing drum 1 to rotate on the mixer's support base 4, one end of the rotating shaft of the connecting gear 23 is connected to the output end of a servo motor 24, which is mounted on the first curved support base 2. The first curved support base 2 is rotatably connected to the support base 4, which is mounted on the mixer. The servo motor 24 controls the rotation of the connecting gear 23 mounted on the first curved support base 2, which in turn drives the meshing drum gear 11. This, in turn, drives the first and second drive gears 21 and 22 on either side of the first curved support base 2, which are respectively meshed with the drum gear 11. This ensures stable rotation of the concrete mixing drum 1, thereby rotating and mixing the concrete mixture in the concrete mixing drum 1. Because the first drive gear 21, the second drive gear 22, and the connecting gear 23 are all mounted on the first curved support base 2 at a predetermined distance from one another and are protected by a protective housing, the possibility of sand and gravel in the concrete mixture causing the first drive gear 21, the second drive gear 22, the connecting gear 23, and the drum gear 11 to become stuck is reduced. Furthermore, the first curved support base 2 is rotatably adapted to the shape of the concrete mixing drum 1. The first drive gears 21 and the second drive gears 22 on either side of the first curved support base 2 act as stable limiters for the concrete mixing drum 1, thereby reducing the possibility of the concrete mixing drum 1 becoming stuck and ensuring stable rotation of the concrete mixing drum 1, thereby fully mixing the concrete mixture in the concrete mixing drum 1.

[0028] Furthermore, in this embodiment, the first curved support base 2 is connected to a first drive shaft 25 via a connecting shaft. The first drive shaft 25 is rotatably connected to one side of the support base 4 via a bearing. A first hydraulic cylinder is disposed between the first curved support base 2 and the support base 4. One end of the first hydraulic cylinder is hingedly connected to the first curved support base 2, and the other end of the first hydraulic cylinder is hingedly connected to the support base 4. This first hydraulic cylinder drives and controls the tilt position of the support base 4, thereby meeting the required tilt when mixing the concrete mixture in the concrete mixing drum 1.

[0029] At the same time, the concrete mixing drum 1 is provided with a second curved support seat 3 at one end away from the first curved support seat 2. A circle of protruding limit sliders 12 are provided on the outer wall of the end of the concrete mixing drum 1 near the second curved support seat 3. Limit rollers 31 are rotatably connected to each other on both sides of the second curved support seat 3 via a rotating shaft. The limit rollers 31 each have a limit slot, and the limit sliders 12 are placed in the limit slot and roll in the limit slot. The second curved support seat 3 and the support base 4 are movable and can be raised and lowered. Furthermore, movable protrusions are connected to each side of the second curved support seat 3. The support base 4 has a limit slot. The movable protrusions are inserted into the limit slot and slide in the limit slot. The second curved support seat 3 and the first curved support seat 2 are connected by two supporting connecting rods. A second hydraulic cylinder is provided between the second curved support seat 3 and the support base 4. One end of the second hydraulic cylinder is hinged to the second curved support seat 3, and the other end of the second hydraulic cylinder is hinged to the support base 4.

[0030] In the embodiment, the first curved support base 2 and the second curved support base 3 are connected together by two supporting connecting rods. When controlling the inclination of the concrete mixing drum 1, the first hydraulic cylinder is controlled to rise and fall, thereby driving the support base 1 to which the first curved support base 2 is rotatably connected via the first drive shaft 25. At this time, the second hydraulic cylinder is controlled to rise and fall (in the same direction as the first hydraulic cylinder), thereby driving the second curved support base 3 to rise and fall along the support base 4. In other words, the first and second curved support bases 2 and 3 are synchronously controlled to rise and fall, driving the concrete mixing drum 1 placed on the first and second curved support bases 2 and 3 to tilt at a certain angle. This satisfies the concrete mix's required tilt angle during mixing, allowing the concrete mixing drum 1 to fully mix the concrete mix in the concrete mixing drum 1 during mixing, thereby meeting the quality requirements for use. It should be noted that the first and second hydraulic cylinders are conventional technologies and are not shown in the accompanying drawings.

[0031] From the perspective of the drive mechanism structure of the design improvement, the drive mechanism adopts "three gears" for transmission engagement, and can adjust and control the inclination of the concrete mixing drum to ensure the entry and exit of the concrete mixing drum and the control of the inclination during mixing to ensure that the concrete mixture in the concrete mixing drum is evenly and fully mixed to meet the requirements.

[0032] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention. At the same time, the various different embodiments of the present invention can also be arbitrarily combined, as long as they do not violate the idea of ​​the present invention, they should also be regarded as the contents disclosed by the present invention.
