The principle of Meijun's road shot blasting machine:

The pellets are quickly thrown into the working area at a certain angle, impacting the surface to roughen the surface and remove residues.

It is to use the centrifugal force and wind force generated by the high-speed rotation of the driving shot blasting wheel to make a certain amount of shot enter the shot pipe, and accelerate it into the rotating shot wheel. It is thrown into the directional sleeve, and then thrown out of the directional sleeve window. It is picked up by the high-speed rotating blade and continues to accelerate along the length of the blade until it is thrown out. The thrown projectile forms a certain fan-shaped flow beam and impacts the working plane. Plays the role of cleaning and strengthening. Then the projectiles, together with dust and impurities, pass through the rebound chamber to the top of the storage hopper. The high-power dust collector separates the pellets and dust through the separation device above the storage hopper. The pellets enter the storage hopper and continue to be recycled, and the dust enters the dust collector through the connecting pipe. When the dust enters the dust collector, it is separated by the filter element and stays in the dust storage hopper and the surface of the filter element. The automatic backflushing dust collector can automatically clean each filter element at intervals by the backflushing air provided by the compressor. Finally, through the airflow cleaning of the matching vacuum cleaner inside the machine, the pellets and the cleaned impurities are recovered separately, and the pellets can be reused. The shot blasting machine is equipped with a dust collector, which can achieve dust-free and pollution-free construction, which not only improves the efficiency, but also protects the environment.

Where to use road shot blasting machine, the use range of road shot blasting machine:

1. It can clean the asphalt pavement, roughen the asphalt pavement while improving the friction force and reducing the slipping accident of the vehicle;

2. You can change the marking lines on the road, remove the old marking lines and draw new marking lines;

3. It can remove the tire marks on the surface of the airport, and it will be very neat and beautiful after cleaning;

4. It is also possible to remove scale, rust and roughen the inner surface of the ship and the surface of the steel plate to meet the pre-treatment requirements of anti-corrosion coating or heavy-duty anti-corrosion coating;

5. It can also be used in tunnel maintenance, the equipment is small and environmentally friendly;

6. It is a better road cleaning tool, and it is not affected by the weather when used;

7. Shot blasting before non-curing waterproof construction can solve the defects of hard hollowing, sanding, cracks, looseness, ash drop, uneven unevenness of the waterproof base layer.

It can be said that the application range of road shot blasting machine is very wide

1. The use of shot blasting machine for asphalt pavement

1. Improve the roughness of the road surface and the adhesion of the road surface

2. Anti-corrosion coating of steel bridge deck

3. Maintenance of heights and tunnels

4. Maintenance of airport runways

5. Removal of markings and cleaning, etc.

6. Refurbishment of oxide layer bridges on ship decks

Steps to start the road shot blasting machine:

1. Turn on the vacuum cleaner

2. Preparing to operate the shot blasting machine

Verify that the valve handle is in the "closed" position,

Press the button "Control ON"

Insert travel pins

Press "Blast Wheel ON", then the shot blasting motor starts;

Observe the ammeter, a larger current is required when the shot blasting motor starts, until the motor reaches a certain speed;

When the motor reaches the rated speed, the current will drop to the no-load current state;

3. Set the walking direction to "Backward", the device will walk, and then set the walking speed of the device at the walking speed adjustment button;

4. When shot blasting on the concrete surface, the valve should only be opened when the machine is running, otherwise, a pit will be thrown on the concrete surface in a short time.

Machine steps of road shot blasting machine

1. Completely close the valve handle;

2. Release the walking pinch handle, the walking motor stops;

3. Press the red "Control Off" button, (Control Off)

4. After a few minutes, press "Fan Off" and "Compressor Off" on the vacuum cleaner

Shot blasting machine maintenance and maintenance

1. Regular lubrication: The motor and transmission parts of the electric actuator of the shot blasting machine need to be lubricated with lubricating oil, and the viscosity of the lubricating oil changes with the oil temperature. If the viscosity is too low, the wear of gears and other transmission parts will increase; if the viscosity is too high, the action will be poor. Therefore, adding lubricating oil regularly can prolong its service life.

2. Improve the operating environment: In order to ensure the reliability of the electric actuator of the shot blasting machine, it must be ensured that it operates in a suitable operating environment to avoid short circuits or other faults caused by other environmental factors such as environmental humidity.

3. Regular inspection: Regular inspection, timely discovery of hidden dangers of accidents in operation, at least helpful in finding fault factors and avoiding detours.

4. Do a good job in the management of the fault account: every fault that has been handled must be recorded in detail, including the fault phenomenon, fault analysis and search process, fault cause, treatment method, preventive measures, etc. This not only provides a reference value for dealing with similar problems in the future, but also improves the level of finding fault factors through the fault curve, achieving a multiplier effect.

The technical advantages of the road shot blasting machine of Meijun Automation Equipment Co., Ltd.:

"Operations and preparations are simple, organize at any time, and evacuate at any time."

A number of leading electrical control technologies such as frequency conversion speed regulation and phase sequence maintenance are selected to ensure the accurate completion of various functions.

Since most of the equipment is used outdoors and the operating environment is harsh and the temperature difference is large, the inverter of this machine is selected from Taiwan, and the other major electrical components are imported from Schneider to ensure the stability of the operation of the electrical appliance and the stability of the whole machine.

All shot blasting machines are subjected to a load test in the factory for 60 minutes to ensure quality.

The centrifugal shot blasting machine with large shot blasting capacity and high shot speed can significantly improve the finishing power and achieve satisfactory finishing quality. The wear-resistant parts are made of high-chromium material.

According to the different conditions of the road surface, the finishing speed, the supply amount of steel shot, the pulse backflushing time period, the cleaning interval of the dust filter cartridge, etc. can be set, and the ideal finishing effect can be achieved through the adjustment of the parameter combination.

The dust collector adopts pulse active back blowing and dust removal, which can complete continuous operations to ensure that the entire construction process is dust-free and pollution-free, which is beneficial to environmental protection and the health of construction workers.

Basically, the pavement structure is not damaged during construction.

The whole machine has reasonable structure, quick disassembly, convenient repair and replacement of wearing parts.
