A kind of anti-sand blowing mechanism used in the sand pool of construction site

Abstract

The invention relates to an anti-sand-blowing mechanism for a construction site sand pit. The mechanism comprises a motor, wherein a turbine reducer is installed at the output end of the motor, rotary rods are symmetrically installed at the two ends of the turbine reducer with the motor as the center, and a winch is connected to the end of each rotary rod; one end of a first traction rope and one end of a second traction rope are wound around the winches respectively, the other end of the first traction rope passes through a second traction wheel, a third traction wheel, a fourth traction wheel, a fifth traction wheel and a seventh traction wheel in sequence to be connected with a gauze sliding mechanism, and the other end of the second traction rope passes through a first traction wheel and a sixth traction wheel in sequence to be connected with the gauze sliding mechanism. The anti-sand-blowing mechanism for the construction site sand pit is simple in structure and convenient to install. By arranging the two traction ropes on the winches, the winches are driven to rotate by means of a power source, automatic stretching and retracting of gauze on the sand pit are realized by means of the transmission action between the two traction ropes and the traction wheels, and sand blowing is avoided.

Description

technical field [0001] The invention relates to civil engineering equipment, in particular to a sand blowing prevention mechanism used for sand pools on construction sites. Background technique [0002] At present, the sand used on construction sites is mainly used for mixing concrete on site, when the main body is building brick walls, mixing mortar for building walls, or for plastering interior walls and exterior walls in the decoration stage, and for flooring of non-rough houses. Most of the sand used is stored in a rectangular sand tank with an opening. Since the sand tank is placed in the open air, the sand will become dry after being exposed to sunlight, and it is easy to cause sand blowing, which not only pollutes the urban air environment, but also affects the construction site. The health of construction workers. Contents of the invention [0003] In view of the above-mentioned existing problems, the applicant has carried out research and improvement, and provide...
