Description

Technical Field

[0002] At present, in my country's construction industry, there are still a large number of walls that use cement mortar plastering technology, which mainly solves the problems of waterproofing and wall leveling. In order to ensure that the verticality and flatness of the wall can be controlled during the plastering construction process, a reference point is required, and the ash cake is to solve the problem of this reference point. The operator can adjust the verticality and flatness of the plastering in real time through the ash cake. At present, the calibration of the ash cake is mainly carried out by pressing and cutting with a ash knife, that is, the mixed cement mortar is shoveled onto the wall with a ash knife, and then with the assistance of a horizontal sweeper, the thickness of the mortar shoveled onto the wall is adjusted (by adding mortar or pressing with a ash knife). After reaching the required thickness, the surrounding excess mortar is cut off to form a cake, referred to as a ash cake.

In this embodiment, it is a Φ25 metal tube, which guides the piston 13; the light sensing belt 7 and the laser leveling device 11 constitute a posture adjustment device, which is used to adjust the posture of the hand-held gun so that the free end port of the ash cake launching tube 8 is perpendicular to the wall or ground where the ash cake is to be made; the input key and the display are used to input the control thickness of the ash cake and transmit the relevant information to the electric device.

[0031] In this embodiment, the control switch 5 is used as a horizontal light and ash cake control switch, which is installed on the hand handle, and its internal circuit is connected to the processor, and the pressing action is transmitted to the processor through an electrical signal; the mortar control device 9, the electric device 10, the grouting pipe 12, the ash cake transmitting tube 8, the light sensing belt 7, and the laser leveling device 11 are all arranged on the machine body, wherein the circuits of the mortar control device 9, the electric device 10, the light sensing belt 7, and the laser leveling device 11 are all connected to the processor, and are opened and closed under the action of the processor, for example: the mortar control device 9 is connected to the grouting pipe 12 and the mortar conveying pipe 4, and its circuit is connected to the processor, and the electrical signal sent by the processor controls the start and close of the mortar control device through the circuit; the electric device 10 is mechanically connected to the grouting pipe 12, and its circuit is connected to the processor, and the processor transmits the electrical signal to the electric device 10 through the circuit to control the mechanical movement of the grouting pipe 12; the circuit of the laser leveling device 11 is connected to the processor, and the opening and closing of the laser leveling device 11 is controlled by an electrical signal.

After receiving the signal, the processor controls the electric device 10 to push the grouting tube 12 while driving the piston 13 to the position h3 away from point a.

[0039] Construction operation method:

[0040] 1. Put the well-proportioned mortar into the backpack through the mortar material port 2, and start the mortar stirring device 16;

[0041] 2. After placing and setting the laser leveler, calculate the ash cake thickness and input the ash cake control thickness value into the input key of the hand-held gun and the display 17;

[0042] 3. Place the muzzle of the hand-held gun at the position where the ash cake needs to be set, and observe whether the laser line of the leveling instrument falls on the light sensing belt 7. If so, start the pressurizing device 1, and the mortar under pressure enters the mortar control device 9 through the mortar conveying pipe 4;

[0043] 4.

At this time, the control switch 5 is in a semi-linked state (the light sensing belt 7 is started, and the sensed light signal is transmitted to the electric device 10 through an electrical signal); after ensuring verticality, continue to press the control switch 5 to the bottom, the mortar control device 9 is started, and the mortar is pressed into the muzzle through the grouting pipe 12. As the grouting continues, the mortar compression piston 13 moves to a position away from the muzzle. When the piston 13 reaches the control position, the electric device 10 will start to rotate the grouting pipe 12, and the rotating baffle 14 is driven by the grouting pipe 12 to rotate and cut the mortar. At the same time, the movable support foot 15 is pushed to the wall or ground through the electric device 10, and the mortar control device 9 also controls the mortar to stop injecting;

[0044] 5. Release the control switch 5 to the semi-linked state, the electric device 10 will start the piston 13 to move toward the wall or the ground, and the barrel of the ash cake launching tube 8 will move away from the wall or the ground under the action of the movable support 15, so as to press the ash cake out of the barrel;

[0045] 6. After taking the nozzle of the ash cake launching tube 8 away from the wall or the ground, completely release the control switch 5. Then the movable support foot 15 will return to its original position, and the ash cake calibration is now completed.

[0046] The above embodiments are only preferred embodiments of the present invention and do not constitute a limitation of the present invention. For easy carrying, rollers can also be installed at the bottom of the backpack, and when in use, the backpack can be pushed to the required position; in addition, the horizontal laser transmitter can also be replaced by a level tube. It should be understood by those skilled in the art that any deformation, extension and equivalent replacement made without departing from the principle of the present invention should be included in the protection scope of the present invention.
