The stable soil mixer road mixer on the market in our country generally has a power above 224kW, and most of them adopt full hydraulic transmission, that is, hydraulic walking transmission, hydraulic working transmission, rear-mounted working device, and no filling agent feeding device is added.

的 The performance of this stable soil mixer cannot meet the needs of high-grade highway construction. Mixing with a stable soil mixer, the mixing material ratio, particle gradation, and water content cannot be accurately controlled, which is inferior to the stable soil plant mixing equipment, and the uniformity, flatness and smoothness of the layer after the road mixer is mixed and formed The compactness is not as good as the stable soil paver, plus the domestic stable soil mixer uses full hydraulic drive, product failures occur frequently, the product quality reliability is too low, the stable soil mixer has a single function, short use time, and machine utilization The rate is low and it is generally resisted by the road construction department with the largest use of stable soil mixers. Instead, the use of stable soil plant mixing equipment and the road pavement base construction technology using stable soil pavers have made the stable soil mixer lose one. Huge market and users.

For low-end users such as county and township roads, at present, the price of high-power full-hydraulic stable soil mixing machines in China is relatively high, and the use cost is too high. As the stable soil mixing machine in China adopts hydraulic walking transmission and hydraulic working rotor transmission, the engine uses high-power international brand diesel engines, and the main components are imported directly from abroad, which makes the manufacturing cost of the machine too high. The price of a whole mixing machine At any time, it can reach 700,000 to 800,000 yuan, and sometimes even as high as one million, which seriously deviates from the value of this kind of product. On the one hand, the vast county and township highways urgently need this kind of equipment to realize the mechanization of road construction, on the other hand, due to its high price, this product makes users "expect the opportunity". In addition, due to the dust and lime flying caused by the on-site mixing of the stable soil mixer, the harsh environment at the construction site is also an important reason why users do not accept this equipment.

To develop a domestic stable soil mixing machine, you must walk on two legs. One is to follow the road of high-power and high-performance stable soil mixing / recycling machine. The other is to develop small and medium-sized users and county and township roads to develop mechanical transmission stable soil mixing that meets China's conditions. Road cold recycler machine.
