Description

Technical Field

[0001] The utility model relates to the field of building construction equipment, in particular to a portable concrete mixer. Background Art

[0002] Concrete mixer is a machine that mixes cement, sand and gravel aggregate and water to make concrete mixture. It is mainly composed of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device. According to the working nature, it can be divided into intermittent (batch) and continuous type; according to the mixing principle, it can be divided into self-falling type and forced type; according to the installation method, it can be divided into fixed type and mobile type; according to the discharging method, it can be divided into tilting type and non-tilting type; according to the mixing drum structure, it can be divided into pear type, drum type, double cone type, disc vertical shaft type and round groove horizontal shaft type.

[0003] Conventional concrete mixers are usually medium-to-large mixers, which occupy a large area. If they are used in the construction of self-built houses in rural areas or in the construction of small buildings, conventional concrete mixers obviously cannot be transported in for use. Therefore, it is necessary to develop a small concrete mixer that is easy to carry and use to meet the use needs in special circumstances.

[0004] The invention patent of Chinese patent application No. 202010340788.6 discloses a concrete mixer, which includes a mixing box, a driving motor is fixedly provided outside the mixing box, the driving motor is connected to a main shaft, the main shaft rotates around its own axis under the action of the driving motor, a stirring paddle is fixedly provided on the main shaft, the stirring paddle is fixedly arranged on the side of the main shaft, a discharging shaft is fixedly provided at one end of the main shaft facing the bottom of the mixing box, a discharging scraper is connected to the discharging shaft, the discharging scraper is separated from the bottom of the inner cavity of the mixing box when the stirring paddle is stirring, and when the mixing box is discharging, the discharging scraper moves toward the bottom of the inner cavity of the mixing box until it contacts the bottom of the inner cavity of the mixing box; a discharging hole is provided at the bottom of the mixing box, and a discharging plate covering the discharging hole is connected to the mixing box; a feeding hole is provided at the top of the mixing box, and a feeding plate covering the feeding hole is connected to the mixing box. The invention has the effect of increasing the discharging rate of the material in the mixing box. The technical solution proposed in the above invention improves the discharge rate of the concrete mixer and thus improves the overall working efficiency of the equipment. However, in actual use, the above solution is obviously not suitable for special construction scenarios due to its large footprint. Utility Model Content

[0005] Therefore, in view of the above problems, the utility model proposes a portable concrete mixer, which solves the problem that the existing concrete mixer occupies too large an area, the overall size of the equipment is also large, and it is difficult to transport to a location with a small space for construction mixing operations.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a portable concrete mixer, comprising a main machine base, an active driving wheel, a driven driving wheel and a stirring roller, wherein an active driving protective cover and a driven driving protective cover are integrally formed on the main machine base, a component accommodating cavity is arranged in the main machine base, an active driving wheel is arranged in the component accommodating cavity, the active driving wheel is driven to rotate by a driving motor, the driven driving wheel is meshed with the active driving wheel and rotates under the drive of the active driving wheel, the stirring roller is fixedly arranged on the driven driving wheel, a portable handle is arranged on the outer side surface of the main machine base, and the stirring roller comprises a rotating roller and a stirring blade.

[0007] Furthermore, there are two driven drive protective covers, which are symmetrically arranged on both sides of the active drive protective cover.

[0008] Furthermore, the rotating roller and the stirring blade are integrally formed, and the stirring blade includes a first stirring part and a second stirring part, the first stirring part and the second stirring part are fixedly connected, the first stirring part is arranged at the upper end of the rotating roller and extends along the lower end of the rotating roller, and the second stirring part is arranged at the lower end of the rotating roller and extends along the upper end of the rotating roller.

[0009] Furthermore, the portable handle is covered with a comfortable and flexible layer.

[0010] Furthermore, an auxiliary pressing portion is provided at the top position on the outer surface of the main machine base.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] Compared with the existing concrete mixers, the biggest advantage of the utility model lies in its portability. Unlike the traditional concrete mixers which are large in size and need to be transported to a designated location like a fixed device, and basically do not change their location until the end of the entire construction period, the portable concrete mixer proposed by the utility model is flexible to use and can be directly carried manually. It can also be used very conveniently in smaller usage scenarios and has more application scenarios. BRIEF DESCRIPTION OF THE DRAWINGS
