Description

Technical Field

[0002] With the acceleration of urbanization construction in China, the demand for mortar is increasing day by day. Mortar is an adhesive substance used for bricklaying in construction, which is made by adding water to a certain proportion of sand and cementitious materials (such as cement, lime paste, clay, etc.), also called mortar. Commonly used mortars include cement mortar, mixed mortar (or cement-lime mortar), lime mortar, and clay mortar. Currently, most of the mortar used on construction sites is transported to the construction site by a dry mortar tank from a dry mortar factory. Dry mortar is a granular or powdery material obtained by physically mixing dried and screened aggregates (such as quartz sand), inorganic cementitious materials (such as cement), and additives (such as polymers) in a certain proportion, and can be directly used after adding water and mixing. The disadvantage of using a dry mortar tank to transport dry mortar is that sand and cement will stratify in the tank, with more sand in the lower part of the tank and more cement in the upper part, resulting in uneven composition and inconvenience for construction at the construction site. Existing dedicated dry mortar production lines have problems such as complex process operations, the need to dry sand, and high production costs. Summary of the Invention

By controlling the opening and closing of the air path solenoid valve 222, the switch of the air inlet is controlled, and the piston inside the vibration cylinder 221 is driven to move back and forth. The piston rod stirs the aggregates in the tank to achieve vibration and prevent the material from falling smoothly. In the case of automatic batching, if the material falling within 2 seconds is less than the "weight for arch breaking of material 1" value on the control cabinet 4, the air-powered vibration device 22 can work automatically.

The one-way solenoid valve 82 is electrically connected to the control circuit board 41. By blowing in gas to break the arch, it prevents the quartz sand from caking in the tank and realizes smooth discharging. In the case of automatic batching, if the feeding amount is less than the "arch-breaking weight of material 1" value on the control cabinet 4 within 2 seconds, the arch-breaking device 8 automatically operates.

The discharging air cylinder 142 is provided with a discharging solenoid valve 143 for controlling the on-off of the air path. The discharging solenoid valve 143 is electrically connected to the control circuit board 41. By controlling the opening and closing of the discharging solenoid valve to control the intake air, the piston in the discharging air cylinder 142 is driven to move back and forth. The movement of the piston drives the pneumatic opening plug plate 141 to realize the opening and closing of the discharge port and complete the discharging control. In the case of automatic batching, the pneumatic discharging device 14 automatically operates. If it automatically discharges after the mixing delay ends, it automatically stops after the discharging delay ends.
