Problems solved by technology

However, the power head of the two-wheel milling cement-soil deep mixer of the prior art also has deficiencies: the vertical plane of the rotation axis of the milling wheel is parallel to the installation side plate where the milling wheel is located, resulting in a limited cutting range of the blade when the power head is lowered, and When the power head sinks, the side plate will be hindered by hard soil, causing the power head to go down smoothly

Embodiment Construction

[0032] Examples, see Figure 1-Figure 9 As shown, a double-wheel milling power head of the present invention includes a mounting frame 1, two milling wheels 2, and a power mechanism. The mounting frame 1 has front and rear side plates 11, and the inner surfaces of the two side plates 11 are equipped with a Milling wheel (that is, the milling wheel is located on the inner surface of the side plate, but not limited to be installed on the side plate), two milling wheels 2 are distributed left and right. The power mechanism is arranged on the mounting frame 1 and connected with the milling wheels to drive the two milling wheels 2 to rotate in reverse; the two milling wheels 2 are respectively inclined to the inside of the two side plates 11, so that the vertical plane of the rotation axis of each milling wheel is in line with the milling wheel. An included angle β is formed between the side plates where the wheels are located (such as Figure 8 shown), the angle β is an acute ang...

Abstract

The invention discloses a double-wheel milling power head and a double-wheel milling deep stirring machine. The double-wheel milling power head comprises a mounting frame, two milling wheels and a power mechanism, the mounting frame is provided with a front side plate and a rear side plate, the inner side faces of the two side plates are provided with the milling wheels correspondingly, and the two milling wheels are distributed in the left-right direction; the power mechanism is arranged on the mounting frame and connected with the milling wheels so as to drive the two milling wheels to rotate reversely; and the two milling wheels are arranged obliquely towards the inner sides of the two side plates correspondingly, so that included angles are correspondingly formed between the vertical planes of the rotating axes of the milling wheels and the side plates where the milling wheels are located, and the included angles are acute angles. According to the double-wheel milling power head and the double-wheel milling deep stirring machine, it can be guaranteed that when the power head is lowered, the cutting range of the two milling wheels is sufficient, when the power head sinks, the side plates are not blocked by hard soil, and thus the power head is lowered smoothly; and through oblique design of the milling wheels, the side faces of the milling wheels laterally push and extrude slurry after the milling wheels cut a soil body to enable the soil body to be mixed with the cement slurry, so that the cement slurry overflows to the inner side and is mixed with the soil body more evenly, and accordingly, the stirring efficiency is improved effectively.

Description

technical field [0001] The invention relates to a pile-forming machine for a water-stop wall of a building foundation pit, in particular to a double-wheel milling power head and a double-wheel milling deep layer mixer. Background technique [0002] At present, there are mainly two kinds of pile-forming machines for the water-stop wall of building foundation pits in my country: three-axis long spiral blade mixing pile machine and two-wheel milling cement-soil deep layer mixer. Among them, the three-axis long spiral blade mixing pile machine has low pile forming efficiency and high energy consumption. Verticality is difficult to control. Due to the high speed of the two-wheel milling power head of the double-wheel milling cement-soil deep mixer (the maximum speed can reach 35 revolutions per minute), the number of cutting tips is large, and the special structural design features ensure that the whole cutting and mixing process is better than that of three-axis drilling. The ti...
