[0002] A concrete mixer is a machine that mixes cement, sand, aggregate, and water to produce concrete. It is a commonly used piece of equipment in construction. In some small construction sites, there is a need for small concrete mixers that offer high mixing efficiency, strong mixing power, and are easy to operate and move.

[0003] Common concrete mixers include a support, a base, and a mixing drum. During use, the mixing drum is supported by the support for mixing, while the base and its rollers facilitate the movement of the concrete mixer, as shown in announcement CN217670203U. However, this method only uses a single set of wheels as the device's walking mechanism, which requires workers to lift the handle and balance the device when moving it. The movement process is quite strenuous, especially when it needs to be moved to locations with complex working conditions, which is very inconvenient and cannot meet the working requirements of concrete mixers. Therefore, a portable concrete mixer for construction is proposed. Utility Model Content

[0028] The mixing tank 5 is mounted on the top of the base frame 1 and connected to the base frame 1 through bearings. The output end of the mixing tank 5 is equipped with a drive motor 6 via a foot bracket. Locking slots 7 are provided on both the left and right sides of the inclined frame 3.

[0029] The auxiliary roller 8 is installed at the bottom of the base frame 1, to the left of the main roller 4. Please refer to [link / reference]. Figure 3 The upper side of the interior of the rear bracket 2 has a connecting groove 9, and a drive rod 10 is inserted into the connecting groove 9. Please refer to [link / reference]. Figure 2 The rear bracket 2 has an insertion slot 11 located below the connecting groove 9. A locking block 12 is inserted into the insertion slot 11, and a drive port 13 is formed inside the locking block 12. The bottom end of the drive rod 10 is inserted into the drive port 13, and the top of the drive port 13 is inclined. An assembly rod 14 is connected to the upper inner side of the locking block 12, and a first spring 15 is sleeved on the outside of the assembly rod 14. The outer ends of the assembly rod 14 and the locking block 12 both pass through corresponding positions of the rear bracket 2. The size of the locking block 12 is adapted to the locking groove 7. Please refer to [link / reference]. Figure 4 Connecting arms 16 are installed on both sides of the bottom of the base frame 1 at positions corresponding to the auxiliary rollers 8. Please refer to [link / reference]. Figures 1 to 3 With the installation of the inclined frame 3 and the rear support 2, when the mixing drum 5 is used, the rear support 2 is locked to the base frame 1, so that the bottom end of the rear support 2 can serve as the rear support point of the device. At this time, the front end of the mixing drum 5 is tilted up and the concrete is mixed. After the mixing is completed, the rear support 2 is lifted so that the rear end of the mixing drum 5 can be tilted up to discharge the concrete. When the mixing drum 5 needs to be moved after the mixing work is completed, the rear support 2 is locked to the inclined frame 3, and then the rear support 2 is lifted. At this time, the main roller 4 and the auxiliary roller 8 will simultaneously abut against the ground. The device has two support points and will be stabilized by itself. Therefore, the operator does not need to hold the rear support 2 to maintain the balance of the device. When moving, the device can be pushed directly, making the movement of the device more labor-saving and improving the ease of use of the concrete mixer.

[0030] Please see Figure 4 Each connecting arm 16 has a base block 17 installed at its inner end, and each base block 17 has a crossbar 18 connected to its inner side. Please refer to [link / reference]. Figure 5 Each base block 17 has a guide rod 19 mounted on its top. Each guide rod 19 is fitted with a mounting plate 20. Each guide rod 19 has a limit plate 27 coaxially mounted on its top. Each mounting plate 20 has a support wheel 21 connected to both sides of its top. Each crossbar 18 has a sliding sleeve 22 fitted on both sides of its outer side. Each guide rod 19 has a second spring 23 fitted on its lower outer side. Each crossbar 18 has a third spring 24 fitted on its outer side outside the sliding sleeve 22. Each sliding sleeve 22 has a hinge rod 26 inserted into its top via a bearing. Angle bracket 25 is installed at the bottom center of the mounting plate 20. The top of the hinge rod 26 is connected to the angle bracket 25 through bearings. An abutment strip 28 is fitted on the outer left side of the mixing tank 5. With the addition of support wheel 21, the abutment strip 28 impacts the support wheel 21 when the mixing tank 5 falls. At the same time, the impact force of the mixing tank 5 on the base frame 1 is reduced by the buffering of the second spring 23 and the third spring 24, thus avoiding the situation of tipping over due to the large impact force when the mixing tank 5 tilts and falls.

[0031] This design utilizes an inclined frame 3 and a rear support 2. When the mixing drum 5 is in use, the rear support 2 is locked to the base frame 1, allowing the bottom of the rear support 2 to serve as the rear support point of the device. At this time, the front of the mixing drum 5 tilts upward to mix the concrete. After mixing, the rear support 2 is lifted to allow the rear of the mixing drum 5 to tilt upward to discharge the concrete. When the mixing drum 5 needs to be moved after mixing, the rear support 2 is locked to the inclined frame 3, and then the rear support 2 is lifted. At this time, the main roller 4 and the auxiliary roller 8 will simultaneously abut against the ground. With two support points, the device will be self-stabilized, eliminating the need for staff to hold the rear support 2 to maintain the balance of the device. Moving the device only requires pushing it directly, making the movement of the device easier and improving the convenience of using the concrete mixer. At the same time, the added support wheel 21 allows the mixing drum 5 to impact the support wheel 21 when it falls, and the second spring 23 and the third spring 24 provide cushioning, reducing the impact force of the mixing drum 5 on the base frame 1 and preventing the mixing drum 5 from tipping over due to the large impact force when tilting and falling.
