Description

Mortar spraying machine

technical field

The utility model relates to the field of construction equipment, in particular to a mortar spraying machine.

Background technique

The existing domestic mortar plastering is basically manual, which has the disadvantages of heavy labor, serious waste of materials, poor working environment, and slow construction speed. The prior art one is manual stirring and then hoisting to the construction site, the labor intensity of workers is high, the cost is high, the efficiency is low, and the transportation is not safe. The second is simple mechanical stirring and then hoisting to the construction site, but it cannot realize the integration of feeding, stirring, conveying, and spraying. The cost is high, the construction is difficult, the time from mixing and mixing to construction is long, and the quality is not stable. The current mortar machine mainly uses the single-shaft paddle mode. Because the single-shaft paddle has a weak ability to transport the slurry, it is easy to cause the mortar to delaminate, bleed, reduce the consistency, and even harden and agglomerate. Once it is pumped to If the nozzle is damaged, it will cause the nozzle to be blocked, which will affect the normal construction and increase the amount of cleaning.

Add mortar from the feed hopper, stir the mortar through the stirring device in the feed hopper, fully stir the mortar and water evenly, and facilitate the transportation of the conveying screw. The leaves further agitate the mortar to avoid blockage of the pump head by the mortar in the delamination and bleeding part. The dual-axis conveying screw is used to increase the ability of the conveying screw to convey mortar.

Preferably, the stirring device includes a stirring motor and a stirring shaft arranged on the stirring motor, and a second stirring blade is arranged on the stirring shaft. Stir the material in the feeding funnel evenly to avoid hardening of the mortar.

Preferably, a vibrating sieve is also provided in the feeding funnel, and the vibrating sieve is arranged below the stirring device. The vibrating screen makes the mortar quickly enter the screw pump from the feeding funnel through vibration, which improves the operating efficiency. It also prevents large pieces of hardened mortar from entering the screw pump and blocking the screw pump, ensuring the normal operation of the device.

As a preference, universal wheels are arranged under the casing, and a controller is also arranged on the casing, and the controller is respectively connected with the driving motor, the stirring device, the vibrating screen, and the screw pump. Universal wheels are set to facilitate the transfer of the position of the casing, reduce the labor intensity of the staff, and improve work efficiency. The controller controls the drive motor, stirring device, vibrating screen, and screw pump respectively, which simplifies the operation of the device and is convenient. worker operation.

Preferably, the height of the helical blade from the shaft core is equal to the height of the first stirring blade from the shaft core, and the first stirring blade is arranged in three equal parts along the circular section of the shaft core. Ensure the normal delivery of the mortar, and at the same time fully ensure the mixing of the mortar to avoid clogging the pump head.

Due to the adoption of the above technical scheme, the utility model has significant technical effects: the mortar is stirred by the stirring device in the feeding funnel, the mortar and water are fully stirred evenly, and the transportation of the conveying screw is convenient, and the mortar is passed through the conveying screw When it is delivered to the pump, the mortar is further stirred by the stirring blades to avoid the blockage of the pump head by the mortar in the layered and bleeding part. The dual-axis conveying screw is used to increase the ability of the conveying screw to convey the mortar, and at the same time make the sprayed The mortar is more uniform, reducing the workload of post-smoothing.
