Example Embodiment

[0011] Such as figure 1 with figure 2 As shown, the spiral concrete mixer of the present invention mainly includes a motor 1, a frame 2, a chassis 10, a mixing barrel 3, and a mixing mechanism. The mixing barrel 3 is installed on a frame, the chassis 10 is fixed at the bottom of the mixing barrel, and two or more mixing mechanisms are provided on the chassis, and the motor 1 drives the mixing mechanism to rotate through a transmission device.

[0012] Each stirring mechanism includes a stirring arm 5 and a spiral blade 4 detachably connected to the stirring arm. The spiral blades on adjacent stirring mechanisms rotate in opposite directions, and the bottom of the stirring barrel is provided with a discharge port 7.

[0013] The transmission device includes a main gear 8 fixed on the chassis, and a secondary gear 9 meshing with the main gear. The number of the secondary gears is the same as the number of the stirring arms, which makes the stirring efficiency higher; at the same tim...

Abstract

The invention discloses a screw type concrete stirrer. The screw type concrete mixer comprises a rack, a stirring bucket arranged on the rack, a bottom disc fixed to the bottom of the stirring bucket, two or more stirring mechanisms arranged on the bottom disc and a motor driving the stirring mechanisms to rotate through a transmission device. Each stirring mechanism comprises a stirring arm and a screw blade detachably connected to the stirring arm, the rotation directions of the screw blades on the adjacent stirring mechanisms are opposite, and a discharging opening is formed in the bottom of the stirring bucket. The rotation directions of the adjacent stirring mechanisms are opposite, the flowing speed of materials in the stirring bucket is improved, and therefore stirring efficiency is improved. In a further embodiment, the screw surface type screw blades are adopted, mixing can be accelerated, and stirring efficiency is higher. Meanwhile, the screw blades can be replaced in time, and maintenance time is saved.

Description

technical field [0001] The invention belongs to the field of mixing material manufacturing equipment, in particular to a spiral concrete mixer. Background technique [0002] Concrete mixer is an important engineering machinery in engineering construction. Its function is to mix cement, water and sand and gravel aggregates and mix them into concrete. The existing concrete mixer is a combination of mixing shaft and blades. As a whole, the motor parts drive the stirring shaft to rotate, thereby driving the blades to rotate, so as to achieve the purpose of mixing concrete. [0003] The mixing shaft and the blades of the existing concrete mixer are a whole, which cannot be disassembled. During use, the coarse aggregate of the concrete usually causes damage to the blades, which makes maintenance more troublesome; in addition, the transportation and movement of the existing concrete mixer is It is completed by the traction of other vehicles, which greatly affects the f...
