Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a slurry-spraying mechanism for building construction walls. Background Technology

[0002] In the construction process, after the walls are built, roughening and finishing operations are performed. Roughening, also called mortar application, is a process before plastering; while finishing is a process after plastering. Both aim to improve adhesion. However, the processing requirements for roughening and finishing are different, resulting in different processing methods and equipment. As the name suggests, roughening involves evenly applying a mortar mixed with a certain water-cement ratio onto the wall using a splashing motion. After reaching a certain strength, plastering is then carried out.

[0003] Existing grouting operations are divided into manual grouting with a grouting paddle and mechanical grouting using a pump. Manual grouting needs to overcome problems such as weight, height, and limited working area, resulting in a large workload, high intensity, and low efficiency. Mechanical grouting requires consideration of the initial investment in equipment and is not suitable for small projects or irregular walls. Based on these problems, this invention was developed. Summary of the Invention

[0004] The purpose of this invention is to provide a slurry-spraying mechanism for building construction walls, which has low investment cost, is labor-saving to operate, and has high work efficiency.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a mortar-spraying mechanism for building construction walls, comprising: a mounting frame; a mortar-holding trough disposed on the mounting frame, having an opening and configured to hold mortar; a mortar-spraying component movably disposed on the mounting frame and configured to form mortar dots; a driving component disposed on the mounting frame and configured to drive the mortar-spraying component to rotate; a switching component disposed on the mounting frame and configured to control the rotating mortar-spraying component to switch between a first position and a second position, wherein when the mortar-spraying component is in the first position, the mortar-spraying component is located outside the mortar-holding trough, and when the mortar-spraying component is in the second position, the mortar-spraying component is located inside the mortar-holding trough; a lifting component connected to the mounting frame and configured to drive the mounting frame to perform lifting movements; and a movable seat connected to the lifting component and configured to perform horizontal movements.

[0006] By adopting the above technical solution, the movable base, in conjunction with the lifting component, realizes the lifting and movement of the mounting frame to cover the surface of the wall to be constructed. While the drive unit drives the slurry-spraying component to rotate, a switching component allows the rotating slurry-spraying component to switch between a first position and a second position. When the slurry-spraying component is in the first position, it is located outside the slurry tank, allowing the rotating component to spray slurry onto the wall. When the slurry-spraying component switches from the first position to the second position, it is located inside the slurry tank and comes into contact with the slurry, causing it to adhere to the component. This process is repeated to achieve the slurry-spraying and slurry-applying operations. This structural design reduces the investment cost of the slurry-spraying mechanism, making it easier to operate and more efficient.

[0007] The slurry ejector is further configured to include a cylindrical slurry ejector cylinder, a plurality of slurry ejector holes distributed on the slurry ejector cylinder, and a slurry storage layer disposed on the inner peripheral wall of the slurry ejector cylinder.

[0008] By adopting the above technical solution, the slurry adheres to the slurry storage layer located on the inner circumferential wall of the slurry throwing cylinder. When the slurry throwing cylinder rotates, the slurry on the slurry storage layer flies out through the slurry throwing hole, thereby realizing the slurry throwing operation.

[0009] The device is further configured to include a drive shaft rotatably mounted on a mounting bracket, with the slurry cylinder fitted onto the drive shaft to move along a circumferential rotation axis. The axis of the drive shaft is parallel to the opening of the slurry tank, and the drive component is connected to the drive shaft.

[0010] By adopting the above technical solution and the above-mentioned structure, the slurry cylinder can have displacement along the drive shaft axis while rotating, thereby realizing the switching of the slurry cylinder between the first position and the second position and entering and exiting the slurry tank.

[0011] The switching component is further configured to include a switching path and a guide sliding structure that slides along the switching path. The switching path includes a first rotation path and a second rotation path that are disposed on the mounting frame and spaced apart along the drive shaft axis and have two ends, a switching path that connects one end of the first rotation path and one end of the second rotation path, and a return path that connects the other end of the first rotation path and the other end of the second rotation path. The switching path and the return path are interconnected and the guide sliding structure is connected to the slurry cylinder.

[0012] By adopting the above technical solution, the slurry cylinder moves along the switching path under the action of the guide sliding structure. When the guide sliding structure is located in the second rotation path, the slurry cylinder is located in the slurry tank and forms a rotating slurry application with the slurry in the tank. This rotating slurry application method allows the slurry to better penetrate into the pores of the slurry storage layer, thereby improving the firmness of the slurry's adhesion to the slurry storage layer and achieving more comprehensive contact between the slurry and the slurry storage layer, avoiding the phenomenon of slurry blistering on the slurry storage layer. Furthermore, the rotation method can also help eliminate air bubbles in the slurry, improving the uniformity of slurry application, thus ensuring the uniformity of subsequent slurry application and improving processing quality.

[0013] When the guide sliding structure moves from the second rotation path into the first rotation path via a switching path, the slurry-throwing cylinder is located outside the slurry-filling trough, thus achieving the rotational slurry-throwing operation. Meanwhile, the guide sliding structure located on the first rotation path then moves back into the second rotation path via a return path, repeating this process to achieve the slurry-filling and slurry-throwing operations. This structural arrangement allows a single drive component to achieve multi-directional drive functions, thereby further reducing the production cost of the mechanism and consequently lowering the initial investment cost.

[0014] The guide sliding structure is further configured to include a guide column fixed to the slurry cylinder and a guide block rotatably disposed on the guide column and having two guide ends, wherein the distance between the guide end and the center of the guide column is greater than the width of the switching path.

[0015] By adopting the above technical solution, the guide column works with the guide block to move along the switching path. This structure allows the guide sliding structure to cross the intersection of the switching path and the return path, thereby ensuring the feasibility of the structure and avoiding structural interference.

[0016] A further configuration is provided whereby when the slurry-throwing component is in the first position, a baffle plate is provided on one side of the slurry-throwing component in the horizontal direction, the side of the baffle plate facing the slurry-throwing component is connected to the opening of the slurry-holding trough and is located directly above the opening of the slurry-holding trough, and a scraping component for cleaning the slurry on the outer peripheral wall of the slurry-throwing cylinder is provided between the first position and the second position.

[0017] By adopting the above technical solution, the baffle plate is designed to prevent slurry from being thrown outwards, thereby avoiding slurry contamination and waste. The slurry blocked by the baffle plate flows into the slurry collection tank, achieving slurry recycling and preventing waste. The slurry scraping component is designed to prevent slurry adhering to the outer wall of the slurry throwing cylinder from sticking to the wall during the throwing process, thus forming substandard slurry protrusions and further improving the processing quality of the slurry throwing process.

[0018] The scraping assembly is further configured to include a fixing ring located on the outer ring of the slurry cylinder and a scraping ring disposed between the fixing ring and the outer peripheral wall of the slurry cylinder.

[0019] By adopting the above technical solution, during the switching process between the first position and the second position, the outer peripheral wall of the slurry cylinder contacts the scraper ring, thereby scraping off the slurry adhering to the outer peripheral wall of the slurry cylinder.

[0020] The lifting component is further configured to include a lifting rod, a guide ring located at the top of the lifting rod, a rotatable spool on the lifting rod, a lifting rope connecting the mounting frame and the spool and passing through the guide ring, and a drive motor for driving the spool to rotate.

[0021] By adopting the above technical solution, the drive motor drives the sheave to rotate, and the lifting rope is wound or released by the sheave to control the lifting and lowering movement of the mounting frame along the lifting rod, thereby changing the height of the mounting frame. This setting method has a simple structure and low cost.

[0022] The lifting rod is further configured to include an upper section for mounting a guide ring, a lower section for mounting a wire wheel, and several adjustable sections that are plugged into each other. The adjustable sections are plugged into both the upper and lower sections, and the mounting bracket is slidably fitted onto the lifting rod.

[0023] By adopting the above technical solution, and through the interlocking adjustment sections, the height of the lifting rod can be adjusted by changing the number of interlocking adjustment sections, thereby adapting to walls of different construction heights and giving the mechanism better versatility.

[0024] The lower section is further configured to be fixed to a movable base, and a counterweight groove is formed on the movable base.

[0025] By adopting the above technical solution, the counterweight groove can be used to add counterweights, which ensures the smooth operation of the mechanism without affecting its convenient handling.

[0026] In summary, the present invention has the following advantages: it has low investment cost, is labor-saving to operate, and has high work efficiency. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The slurry-dispensing component 3 includes a cylindrical slurry-dispensing cylinder 31, several slurry-dispensing holes 32 distributed on the slurry-dispensing cylinder 31, and a slurry-retaining layer 33 fixedly disposed on the inner circumferential wall of the slurry-dispensing cylinder 31. The slurry-retaining layer 33 is composed of several cylindrical metal meshes fixedly stacked together. It includes a drive shaft 8 rotatably disposed on the mounting frame 1 and passing through the slurry-filling tank 2, the drive shaft 8 being rotatably engaged with the slurry-filling tank 2. The slurry-dispensing cylinder 31 is fitted onto the drive shaft 8 to achieve circumferential rotational movement. The axis of the drive shaft 8 is parallel to the opening orientation of the slurry-filling tank 2. A drive component 4 is connected to the drive shaft 8.
