Concrete Mixer with their hands : turn-based technology and video

The drive can use electric or gasoline engine, manual transmission and can be used to perform the most simple mixer.For the electric motor can be used by a washing machine - it will provide the necessary force and speed.Mixer motor with easy to use, but require a network connection, which limits its field of use.Gasoline engines of the motorcycle unit will make a universal, concrete mixer can be used on any site.

frame design depends on the type of drive and bucket configuration.Welded corner frame of metal tubes or in form of a triangular or trapezoidal base, fixed to it and the drive axis of rotation.For the convenience of the ready solution equipped with pivoting frame system, equipped with a counterweight mounted to avoid inadvertent stall.

Manufacturing tub

Tub mixer to mixer must have sufficient strength, so its manufacture requires a metal of at least 2 mm thick.The bottom of the tub is made of thicker metal 5 mm.The neck portion tapers to a bucket of a cone.Drawing bucket is shown in the figure.

technology implementation-tub mixer:

1. steel flange hub perform the drawing.You can use ready-made piece of suitable size.From
2. 5 mm steel sheet cuts out the bottom to form a circle, mark and drill the holes 8 therein of 6.5 mm diameter for mounting the hub flange, in accordance with the drawing.
3. steel 2mm cuts out shell width of 150 mm and a cone petals - 4 pieces.
4. Details flex pattern, or with a vise and a hammer.With
5. welding machine connected to the pitch cone forming neck.It is welded to the cone shell, increasing its steel band welded bottom.Sutures are cleaned of scale.
6. neck should be strengthened to avoid its deformation.This can be done using 10mm rebars bent to the desired radius of the circle.Bars are welded along the outer edge of the neck at a distance of 1 cm, then the folded edge and is expanded outward around its rod.
7. Inside the tub additionally welded crosswise three divider made of rebar of 16 mm, bent at a right angle.They will give additional strength to the structure and improve the mixing of the solution conditions.

frame Making concrete mixers concrete mixers

Frame made of metal pipe.Due to the wheels concrete mixer easy to move on the building site even when filled with solution.For greater stability of the legs are welded to the frame-support.The frame is mounted tub mixer, actuator and gearbox.The drawing is shown in Fig.

frame manufacturing technology and assembly of concrete mixers:

1. Base frame - longitudinal and transverse beams of pipe 60h20 mm, welded in a T-shaped structure.These welded at the junction of the vertical stand.The base frame is strengthened inclined strut bar and attached by welding.
2. wheels attached to the transverse beam via the wheel axle.For the mixer, you can use the wheel of the car, an old agricultural or motorcycles, they can be both metal and tires.
3. feet of pipe welded to it glides out of sheet metal bonded bridge and welded to the frame.
4. to tilt the front panel is welded to the condenser box and the starter - with their help made the inclusion of the rotation mechanism.
5. subframe, which is attached to the tub-mixer, made of tubes and angle and is a double frame with a jumper.For subframe welded lugs, through which by means of bolting subframe slidably mounted to the posts.
6. on a stretcher fixed motor and worm gear.Number of gear transmissions should provide rotation at 20-40 rpm.Motor - three-phase, powered by 380 V AC, engine power - not less than 1 kW.When attaching the transmission mechanisms is necessary to observe the alignment.
7. K-tub mixer on the bolts securing the flange hub, then put the mixer in the splined shaft of the gearbox.The mixer is fixed key and fix a bolt through the hole on the shaft.
8. handle attached to the subframe, by which the mixer is set in different positions: at an angle of 40 degrees - mixing heavy concrete, an angle of 60 degrees - for the preparation of masonry mortar, an angle of 90 degrees - for washing-tub mixer.Pen enhance scarf made of sheet steel, pen tip can be made from a piece of rubber hose.
9. to secure mixer in position using an arcuate sector angle adjustment with holes corresponding to the tilt axis of the mixer.It is made of a metal plate is attached to the subframe with the bolt welded to the eyelet.Used for fixation pin of suitable diameter, for convenience it is engaged by the chain to the frame.
10. All frame parts cleaned of scale and cover the paint on metal.Friction elements lubricated with grease every axis.

Using mixer

download components produced manually by tilting concrete mixers 20-40 degrees.Priority loading of the components is:

• Water Cement Sand
• large fraction (crushed stone, gravel, concrete block).

Average time of mixing concrete - from 3 to 5 minutes.Unloading the mixture to the bucket by turning the frame with the lever, the pin holding the bucket in the desired position, the sector is taken out of adjustment.

After work-tub must be cleaned of residual mortar mixer, to which it is brought down as much as possible and slightly tapped orifice from the outside, washed with water if necessary.

Performance mixer allows you pour a strip foundation of a private house or a cottage for a few days of work.In the manufacture of parts quality cement mixer has enough strength and resources to use it for ten years or more.
