Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction tools, specifically a powder-spreading and line-laying device for construction. Background Technology
[0002] In construction projects, it is often necessary to apply powder to mark out lines before proceeding to the next step. Furthermore, this powder application and marking often occurs on the critical path of the construction network. The usual method for applying the powder is to use a shovel and another object to tap and strike the powder while walking forward, which is both inaccurate and slow.
[0003] When spreading white powder, the usual method is to hold a shovel and use another tool to tap while walking forward, which is inaccurate and slow. There are some wheeled powder spreading tools on the market, which are stable and precise, but can only be used on very flat ground and are not suitable for complex terrain in the wild. Other shoulder-mounted or handheld powder spreading tools are single-handed and can be used in complex terrain, but the amplitude of hand tremors is amplified by the extension of the spreading tool's outlet. The radius from the shoulder to the outlet is generally 1.4-1.5 meters. If spreading powder on flat ground, even slight arm tremors while moving forward can cause the spread line to bend by several centimeters, resulting in significant errors. In the wild, especially in complex terrain such as uphill, downhill, groves, and rocky areas, the spreading accuracy is very poor, and the spread line is crooked. Spreading powder is primarily done outdoors and is easily affected by wind, causing the spread line to be crooked or uneven in width. Due to the different materials used in the casting powder, the speed at which the powder flows out during casting varies. At the same time, the casting powder will become damp to varying degrees during storage, especially in the rainy season or in humid southern regions. These two factors cause a large difference in the speed at which the powder flows out during casting. Sometimes no powder flows out at all, and sometimes the powder flows out too quickly. The sand avalanche effect of the casting powder in the container will also cause the powder to flow out at different speeds, making it difficult to control. Utility Model Content
