Problems solved by technology

[0002] Ordinary mixing drilling rigs include a drilling bit and a stirring rod. When the drill is lowered, the drilling bit is drilled, and the stirring rod is stirring at the same time, which requires a lot of power. When the drill is lifted, because there is no drilling power, only stirring power is required, which requires less power. ;Because the maximum power needs to be considered when configuring the power, the configuration power is very large, and a small power is required when lifting the drill, which will cause waste of energy

Embodiment Construction

[0012] Accompanying drawing is a kind of specific embodiment of the present invention, and this embodiment drilling rod 1 lower end is equipped with drilling bit 6, and drilling bit top is equipped with many groups of long stirring rods 5, and each long stirring rod lower end is hinged on drilling rod, The upper part of each group of long stirring rods is provided with a screw cap, and a short stirring rod 4 is respectively fixed on the left and right sides of each screw cap 3. On the drill pipe, the other end is fixed to the long stirring rod; when drilling down, the upper end of each long stirring rod is gathered in the screw cap, and when the drill is lifted, each long stirring rod is in a horizontal state.

[0013] When the drill rod is drilled in the present invention, the drill rod drives the drill bit to rotate forward. Due to the reaction force of the soil on the short stirring rod, the short stirring rod reversely twists the screw cap, and the screw cap moves downward,...

Abstract

Provided is an energy-saving stirring drilling machine. A drilling drill bit is installed at the lower end of a drill rod, multiple sets of long stir rods are installed on the upper portion of the drilling drill bit, the lower end of each long stir rod is hinged to the drill rod, short stir rods are fixed on the left side and the right side of each screwed cap respectively, the screwed caps are screwed on lead screws which are parts of the drill rod, one end of each elastic piece is fixed on the drill rod, and the other end of the corresponding elastic piece is fixed on the corresponding long stir rod; when the drill rod is dropped down, the upper end of each long stir rod is folded in the corresponding screwed cap, and when the drill rod is lifted, each long stir rod is in a horizontal state.

Description

technical field [0001] The invention relates to a mixing drilling machine, in particular to an energy-saving mixing drilling machine used in a mixing pile reinforcement project. Background technique [0002] Ordinary mixing drilling rigs include a drilling bit and a stirring rod. When the drill is lowered, the drilling bit is drilled, and the stirring rod is stirring at the same time, which requires a lot of power. When the drill is lifted, because there is no drilling power, only stirring power is required, which requires less power. ; Due to the need to consider the maximum power when configuring the power, the configuration power is very large, and less power is needed when lifting the drill, which will cause energy waste. Contents of the invention [0003] The present invention makes up for the above shortcomings and provides an energy-saving mixing drilling machine. [0004] The present invention is achieved through the following technical solutions: [0005] An ene...
