Description

Technical Field

[0001] This invention belongs to the field of building equipment technology, and specifically relates to a building wall plastering device. Background Technology

[0002] Currently, the construction industry is becoming increasingly mechanized, with many construction projects replacing traditional manual labor with mechanized operations. Mechanized operations not only significantly reduce the labor intensity of construction workers but also ensure the quality and compliance of projects.

[0003] However, plastering machines currently used for plastering interior and exterior walls of buildings have many problems in actual operation, such as: 1. They have drawbacks such as complicated operation procedures, numerous operators, frequent plastering, and inconvenience in adding plaster. They also commonly suffer from the problem of "not being able to plaster the top or bottom," requiring manual patching of the already plastered wall surface after completion, thus wasting a significant amount of time, manpower, and resources; 2. Traditional plastering machines achieve plaster thickness and verticality through frequent manual adjustments during construction, which wastes time and results in an unsightly finish; 3. Operators use scaffolding to operate traditional plastering machines. For example, adjusting the height of the scaffolding is used to operate the machine up and down, and moving the scaffolding is used to operate it left and right. This poses certain safety hazards for operators and is time-consuming and labor-intensive.

[0004] Therefore, a new plastering device is needed to solve the above-mentioned technical problems. Summary of the Invention

[0032] A measuring rod 11-1-8 is provided on the force-bearing rod 11-1-2, which passes through the rod body 11-1-1, and the measuring rod 11-1-8 is provided with scale lines.

[0033] To facilitate the movement of the device, a support rod 13 is provided on the side of one of the upright plates 4, and a handle 14 is provided on the support rod 13.

[0034] The specific working principle of this invention is as follows: First, the staff sets the number of rotations of the stepper motor 7 and the conveying speed of the material pump 9-10 based on experience. Then, the base frame 1 is moved to the starting position, and the plaster shell 12-12 is placed in the initial position and attached to the bottom of the wall. The uprights 10 and climbing components 11 are then set to a suitable height according to the height of the wall. The mortar is then poured into the tank 9-1, and the material pump 9-10 is started.

[0035] The feed pump 9-10 draws mortar from tank 9-1 and discharges it into annular pipe 9-5-2. The mortar then enters outer casing 9-5-1, driving fan blade 9-5-1 and causing shaft 9-5-6 to rotate. The stirring rod 9-6 and spiral stirring blade 9-7 agitate the mortar in tank 9-1. The mortar then exits from outlet 9-5-5 and flows through feed pipe 16 into tee pipe 12-3. Subsequently, the mortar enters outer casing 12-1 from inlet 12-2, where it impacts fan blade 12-6, causing it to rotate. The rotation of shaft 12-5 causes the drive gear 12-7 to rotate. Then, mortar is discharged from outlet 12-8 and enters the plastering shell 12-12 through connecting pipe 12-13. The mortar is then discharged from outlet 12-12-5 and applied to the wall. As the mortar is discharged, the plastering shell 12-12 moves backward, causing the elastic rod 12-10 to be squeezed until the drive gear 12-7 meshes with the toothed belt 11-1-4 in the climbing component 11. Under the action of the drive gear 12-7, the actuating component 12 begins to move upward gradually.

[0036] When the reversing switch 12-12-4 on the top of the plaster shell 12-12 touches the top of the wall, the stepper motor 7 rotates a certain number of times, causing the base 8 to move a certain distance. Then, the controller 15 closes the solenoid valve of the current input port 12-2 and opens the solenoid valve of the other input port 12-2. The mortar enters the outer shell 12-1 from the other input port 12-2. Then, the drive gear 12-7 reverses and moves down along the climbing component 11. This process is repeated until the base 8 touches the contact switch on the upright plate 4. Then, the controller 15 shuts off the delivery pump. After the staff adjusts the position of the base frame 1 and the position of the base 8, the delivery pump is turned on again.

[0037] It should be noted that, according to the required mortar application thickness, the position of the rod 11-1-1 in the climbing assembly 11 can be adjusted by observing the measuring rod 11-1-8. Additionally, when applying mortar to the wall, if there are no obstacles at the top of the wall, a level can be fixed at the top of the wall to trigger the reversing switch 12-12-4, depending on the actual situation.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
