Hopper plaster bucket (air shovel), Kyiv

Description of the equipment:

Specialists who deal with construction work have encountered a situation when it is necessary to apply a large amount of concrete mixtures, plasters, cement mortars, etc. in a short time. Manually, this work is a very time-consuming and far from profitable process, andshovel a hopper bucket (pneumo bucket) can significantly simplify the task - it is mobile and easy to move. Using such a tool, any unskilled worker can perform all manipulations in the best possible way in a shorter period of time.
Such a technology for coating walls, ceilings, and building facades is carried out through a compressor with constant pressure. Advantages of this tool:
• Work with a bucket is available to anyone, there is no need for a qualified and well-known professional. One worker can plaster 30 to 60 square meters. meters with a layer of up to 3 cm per time.
• Time for plaster work is reduced by 3-4 times.
• The force of impact of the mixture on the surface is much higher than with manual application, therefore the quality of applied concrete increases. Better adhesion of solutions to the walls and ceiling is ensured.
No special requirements for applied solutions
It is allowed to use anyadditives and fibers, due to exit nozzles of 20 mm
• Thanks to this plaster application technology, the consumption of the mixture is significantly reduced for two reasons:(//tractor-service.com)
1. Thin layer
2. Reduction of waste material costs.

Acceptable price. Payback in one day.
(After each use, the hopper bucket must be cleaned of solution. To do this, blow the nozzles with compressed air, rinse with water, and dry.)

It is forbidden to operate the device at a pressure higher than 6 atmospheres in order to avoid accidents.
The ladle of the device consists of a steel container, where the solution for application to the walls is placed. In the container, there are 4 nozzles in front for supplying the solution, for air release. Also, the device is equipped with a holder tube with a non-slip coating, which also serves to supply compressed air, a non-return valve for compressed air, and a connector.
To maintain the pressure of compressed air within the range of 3-6 atmospheres, a compressor with a capacity of at least 3 l/s, a hose (25 meters, with a diameter of 13 mm.) and a regulator of the pressure level of the compressed air coming from the compressor are required. To ensure the application of an even layer of solution, the pressure should be maintained within 4 atm., but it is possible to increase the pressure up to 6 atm. to compensate for air loss during hose feeding.
The distance between the bucket and the wall when applying the solution should be 5-10 cm, the distance can be reduced to 2-3 cm to obtain the optimal thickness of the layer and prevent the formation of voids in the applied layer.
For spraying (direct application of the solution to the wall in a small amount to create a supporting base for further application), it is necessary to remove the bucket at a sufficient distance from the wall and quickly apply the required amount of solution, increasing the pressure if necessary. info.
