JS series concrete mixer detailed description and maintenance

Concrete mixer is a machine that mixes cement, sand and gravel aggregates and water and mixes it into concrete mixture. It is widely used in various engineering sites and is a best-selling concrete mixer equipment. How to choose the right concrete mixer equipment for you? The detailed instructions and maintenance of the concrete mixer below may be helpful to you.

1. JS series concrete mixer mixing device

The main components of JS series mixer mixing device include: mixing shaft, mixing arm, mixing drum, mixing blade and side blade. The two mixing shafts are installed horizontally in the mixing drum of the mixer, and the mixing blades are installed on the mixing shafts. The mixing arms near the two ends of the mixing drum are also equipped with side blades, which help to scrape off the bonded concrete on the end face and change the mixing flow direction of the concrete;

2. JS series concrete mixer loading and unloading device

When feeding the JS series mixer, put the weighed aggregate mixture into the hopper, and then start the feeding device. The hopper is pulled by a wire rope and climbs upwards at an average speed. When climbing to the designated place, the hopper will automatically open after entering the feeding rack, and the material in the hopper will be discharged into the mixing drum through the hopper;

3. JS series concrete mixer transmission device

JS series mixer transmission device is mainly composed of reducer, pulley, motor, open gear and so on. The power is driven by the pulley motor, and the two horizontally arranged stirring shafts are composed of two small opening gears and two large opening gears;

4. JS series concrete mixer water supply device

The water supply device of JS series mixer mainly includes motor, pump, throttle valve, cleaning device, water spray pipe, etc. Concrete mixing water is delivered to the water spray pipe through the throttle valve of the pump, which can adjust the flow of water;

5. JS series concrete mixer electrical control device

The control buttons, indicator lights and air switch handles of JS series mixers are all located on the distribution box and are equipped with door locks. There is a protective cover on the button.

The above is the introduction of JS series concrete mixer. Concrete mixer is a special equipment for producing concrete. Due to its long use time and large workload, it is more important to carry out maintenance, repair, maintenance and replacement of worn parts according to the specified time. The following introduces the aspects that should be paid attention to during the maintenance of the concrete mixer from these aspects.

1. Concrete mixer transmission system

The transmission gear, reduction box and chain of the mixer shall be lubricated according to the regulations;

The sound of the transmission part is normal, and the reduction box and bearing have no heating phenomenon;

The triangle conveyor belt is properly tight;

The steel wire rope should not have large wear, the chuck and the connection should be firm, and the surface should be greased and lubricated;

The performance of the brake and clutch is good, and the brake pads should be replaced if they are worn out.

2. Other lubricating parts of concrete mixer

The main engine is started or the shaft end seal of the mixer is filled with oil according to the specified time, so that the oil seal structure can work normally for a long time;

Other refueling points, such as rotating, rotating wheels and tracks, etc., should be refueled at the specified time.

3. Concrete mixer mixing system

Check whether the mixing drum is running stably, and the lining plate and blade should be replaced if damaged;

Clean up the concrete stuck in the mixer according to the specified time.

4. Concrete mixer cleaning and fastening

The installation and connection of the main engine, bracket, loading bracket and other facilities should be firm;

Cleaning of concrete mixer body, site, etc.;

There should be no stagnant water around the foundation, and the waterway should be insulated during the freezing season.

It is May, and it is about to enter summer. Summer is hot and humid. The suction pipe, the periphery of the sleeve, and the inner rod of the concrete mixer are very easy to corrode. It must be checked frequently and painted with wear-resistant paint.

In the heat dissipation work of the concrete mixer, especially the heat dissipation of the mixing box and the reducer. Put the blender in a place with air circulation as much as possible to reduce corrosion. In the sweltering heat of summer, it is necessary to regularly check and adjust the surface tension of the mixer drive belt and the looseness of the anchor bolts. At the same time, do a good job of waterproofing and rainproofing, especially the cables and power plugs that connect the mixer to the electricity. For safety, please turn off the power switch of the blender immediately when not in use. In summer, the temperature is high, and the water volatilizes quickly. After the concrete mixer works, the concrete in the mixing tank must be cleaned immediately. When brushing the machine, use clean water to turn over the mixer tank for 10-15 minutes, and then remove the water and stones. In this step, disconnect the switching power supply to avoid power failure and prevent concrete from condensing in the main tank, which will endanger the working characteristics and service life of the mixer. Carefully check the lubrication of the rotating shaft of the mixer, and carry out grease lubrication at the lubrication point once a week.
