Description

Technical Field

[0001] This invention relates to a concrete mixing drum, and more particularly to an excavator concrete mixing drum powered by a mixer and using the mixer's bucket as the mixing tool. Background Technology

[0002] Currently, all known concrete mixers are powered by electricity. These machines offer high efficiency and speed in concrete mixing, playing a significant role in urban construction, highways, and bridge building. However, a drawback is the insufficient capacity of the mixer's bucket; furthermore, in remote, unpowered areas, these electrically powered mixers are ineffective. As described in this invention, a concrete bucket powered by excavation, using the mixer's bucket as the mixing tool, has not been reported. Summary of the Invention

[0003] To overcome the shortcomings of the aforementioned concrete mixers, such as insufficient capacity of the mixing hopper and the need for electricity as a power source, this invention provides an excavator concrete mixing hopper. The hopper of this invention has a larger capacity than that of existing concrete mixers and does not require electricity as a power source. Instead, it utilizes the power of the excavator, using the excavator's bucket as a mixing tool to directly mix the concrete inside the hopper.

[0004] The technical solution adopted by the present invention to solve its technical problem is as follows: The mixing tank is composed of a material tank, a material tank base frame and a distance adjustment rod. The material tank is an off-center semi-circular body. A water pipe is fixedly connected to one corner of the upper edge of its rear side. The end located inside the material tank is the water outlet, and the end located outside the material tank is the water inlet. The upper part of the outer surface of its front side has a fixed seat on the distance adjustment rod, which is fixedly connected to it. The upper part of its two semi-circular sides has a rope loop hole. There are rope loops on the two rope loop holes. One end of the rope is fixedly connected to one rope loop, and the other end is connected to a hook. There is a material tank drain hole at the bottom of the material tank. The base frame of the material bucket is fixedly connected to the material bucket at the bottom. There is a lower fixing seat of the distance adjustment rod fixedly connected to it on the bottom edge of its front part. The upper and lower ends of the distance adjustment rod, which is separated from the material bucket, are respectively installed on the upper fixing seat and the lower fixing seat of the distance adjustment rod. The distance adjustment rod consists of an outer sleeve and an inner rod. The outer sleeve and the inner rod have distance adjustment fixing nail holes on the outer sleeve and the inner rod, respectively. The top of the inner rod has a connecting sleeve fixedly connected to it. The connecting sleeve has a connecting hole. The inner rod is located inside the outer sleeve and can extend and retract inside the outer sleeve. The distance adjustment rod can rotate around the fixing nail of the lower fixing seat. During operation, first place the bucket at a suitable position between it and the excavator. Then, loosen the fixing screw on the upper fixing seat of the distance adjustment rod, and rotate the distance adjustment rod outward. Next, pull the inner rod out of the outer sleeve and fix the connecting sleeve to the excavator through the connecting hole on the inner rod's connecting sleeve, using a connecting rod or wire rope. Finally, tighten the distance adjustment fixing screw through the distance adjustment fixing screw holes on the outer sleeve and inner rod, thus completing the connection between the bucket and the excavator. Place cement and sand into the bucket, connect the water pipe to the water inlet on the rear side of the bucket to mix the water with the cement and sand inside. Start the excavator, and the bucket bucket will begin mixing the concrete. After completion, use the bucket hoisting rope to lift the bucket onto a vehicle for transport to other construction sites for continued work. Because of the excavator's powerful engine, even with a relatively large bucket capacity and a large amount of cement and sand, the excavator bucket can mix the concrete evenly and quickly, ensuring both the quantity and quality of the concrete. If the concrete bucket is empty and rain causes water to accumulate inside, the water will drain out automatically through the bucket's drain hole.

[0005] The beneficial effects of this invention are that, because it is powered by an excavator, it can still mix concrete at construction sites without power, without affecting construction; at the same time, because the material bucket has a large capacity, it can be used for a relatively long time to mix concrete once, reducing the number of times the excavator needs to mix, saving the excavator's energy, making it energy-efficient, economical and practical.

For example, the shape and positional relationships of the components of the invention should not be limited thereto. Attached Figure Description
