DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] As Figure 1-2 shown, the present invention provides a construction site lofting tool, including a storage component 100. The storage component 100 includes a storage pipe 101, a handle 102, a push rod 103, and a plunger 104. The push rod 103 is arranged inside the storage pipe 101, the push rod 103 penetrates through the plunger 104, and the handle 102 is fixed to the outer end of the push rod 103;

[0025] The diversion assembly 200 is provided at the front end of the material storage assembly 100. The diversion assembly 200 includes a connection block 201, a diversion pipe 202, a fixed cylinder 204, an expansion joint 205, a connection head 207, and a diversion head 208. The diversion pipe 202 and the fixed cylinder 204 are both provided on the bottom side of the connection block 201. The expansion joint 205 is provided inside the fixed cylinder 204. The connection head 207 is provided at the bottom end of the diversion pipe 202. The diversion head 208 is provided inside the connection head 207.

[0026] The ash spreading assembly 300 is provided at the bottom end of the diversion head 208. The ash spreading assembly 300 includes a positioning ring 301 and a positioning rod 302. The positioning rod 302 is fixed inside the positioning ring 301. An ash spreading opening 303 is formed at the bottom of the positioning ring 301.

[0027] Further, in this embodiment, the plunger 104 is in threaded cooperation with the push rod 103. The plunger 104 is made of rubber. A spring 105 is provided inside the outer end of the material storage pipe 101 close to it. A damping block 106 is fixed at the end of the spring 105. By the material of the plunger 104, the airtightness inside the material storage pipe 101 is improved.

[0028] In this embodiment, the two ends of the spring 105 are respectively fixedly connected to the damping block 106 and the material storage pipe 101. The push rod 103 penetrates through the damping block 106, is located inside the spring 105, and is slidably connected to the damping block 106. By pulling the damping block 106 through the spring 105, the damping block 106 is prevented from being pulled out by the push rod 103. The movement of the push rod 103 is stabilized by the damping block 106, ensuring the stable and slow movement of the push rod 103 and preventing excessive amount of white ash from being spilled due to the too fast movement of the push rod 103.

[0029] In this embodiment, the connection block 201 is of an L-shaped design. The front end of the material storage pipe 101 is in threaded cooperation with one end of the connection block 201. The inlet end of the diversion pipe 202 is in threaded cooperation with the other end of the connection block 201. A diversion pipe 206 is provided between the diversion pipe 202 and the material storage pipe 101. The material storage pipe 101 is connected to the diversion pipe 202 through the connection block 201 and is communicated through the diversion pipe 206, enabling the material storage pipe 101 to be communicated with the diversion pipe 202.

[0030] In this embodiment, the diversion pipe 202 is communicated with the material storage pipe 101 through the diversion pipe 206. A connection column 203 is provided between the fixed cylinder 204 and the connection block 201. The connection column 203 is fixed at the bottom of the connection block 201 and is in threaded cooperation with the fixed cylinder 204. The fixed cylinder 204 is installed under the connection block 201 through the connection column 203.

[0031] In this embodiment, the fixed cylinder 204 is sleeved outside the expansion joint 205. Inside the fixed cylinder 204, there are several expansion joints 205 with gradually decreasing diameters. A limit bolt 209 is provided between the expansion joint 205 and the fixed cylinder 204. The expansion column composed of the expansion joints 205 can be telescoped, and each section of the expansion column is limited by the penetration of the limit bolt 209, enabling the staff to hold it by the expansion column.

[0032] In addition, considering personal usage habits and comfort, the installation directions of the fixed cylinder 204 and the expansion column can be horizontal or vertical. Only by changing the installation direction of the fixed cylinder 204 and the connecting column 203 and reasonably designing the structural shape of the actual connection part.

[0033] In this embodiment, at least three positioning rods 302 are fixed inside the positioning ring 301. A central block is fixed at the front ends of the three positioning rods 302. The central block is in threaded cooperation with the connecting head 207 and is communicated with the diversion head 208. The positioning points are positioned through the positioning rods 302 and the central block.

[0034] In this embodiment, both the positioning rod 302 and the positioning ring 301 are designed with hollow interiors. The positioning ring 301 and the central block are communicated through the positioning rod 302. Ash-dispensing openings 303 are provided at the bottoms of both the positioning ring 301 and the central block. Through the design of the positioning ring 301 and the positioning rod 302, the white ash introduced from the connecting block 201 can enter the positioning ring 301 through the central block and the positioning rod 302 and be ejected from the ash-dispensing opening 303 for ash-dispensing work.

[0035] In addition, considering that the white ash needs to pass through the central block first and may be ejected from the central block without entering the positioning rod 302, the height of the ash-dispensing opening 303 on the central block does not exceed the bottom end of the communication port between the positioning rod 302 and the central block, ensuring that after the white ash enters the central block, part of it will enter the positioning rod 302 and part of it will be ejected from the central block, preventing the white ash from being directly ejected from the central block due to the spraying pressure and ignoring the positioning rod 302. Moreover, the diameter of the ash-dispensing opening 303 on the central block is smaller than that on the positioning ring 301, so as to give the white ash time to flow in the positioning ring 301, slow down the flow rate of the white ash in the positioning ring 301, and give the white ash enough time to be evenly distributed in the positioning ring 301, avoiding excessive accumulation of white ash at the center of the positioning point due to too fast flow.

[0036] Specifically, when starting to use, first use GPS to measure and mark the center point of the lofting. Then, the staff adjusts the telescopic joint 205 to an appropriate length and fixes it with fastening bolts. Hold the telescopic joint 205 by hand, then align the positioning ring 301 with the marked point. Then, the other hand can push the push rod 103 to apply pressure to the inside of the storage pipe 101, pushing out the lime inside. The lime passes through the connecting block 201, through the drainage pipe 206, the diversion pipe 202, the connector 207, and the diversion head 208, enters the positioning ring 301, and sprays out the lime through the ash spreading port 303, forming an origin array on the ground. When continuously pressing, the staff controls the tool to rotate and draw a circle along the center block to complete the positioning;

[0037] The storage component 100 is composed of a storage pipe 101, a plunger 104, and a push rod 103 with a handle 102. A sealed space is formed between the storage pipe 101 and the plunger 104 for loading lime. Before using the tool, first align the diversion head 208 with the position where the lime is stored, and then control the handle 102 to pull the plunger 104 on the push rod 103 to create a negative pressure inside the storage pipe 101, so that the lime will be sucked into the storage pipe 101. When the positioning ring 301 is aligned with the positioning point, push the plunger 104 through the push rod 103 to increase the pressure inside the storage pipe 101, and push out the lime through the pressure, and spray it out through the ash spreading port 303;

[0038] Considering the convenience of tool use, a connecting column 203 is provided on the bottom side of the connecting block 201 to install the handheld part. The handheld part is composed of a fixed cylinder 204 and several telescopic joints 205. By adjusting the extended length of the telescopic joint 205 and limiting it with a limit bolt 209, the staff can hold the telescopic joint 205 with one hand and control the push rod 103 with the other hand to operate the tool. Considering comfort, a rubber gasket can be wrapped on the outer surface of the telescopic joint 205, which can not only improve the comfort of holding but also stabilize the movement of the telescopic joint 205.

[0039] In addition, the speed and strength of the plunger 104's push determine the spraying speed of the lime. The storage pipe 101 is set to be transparent, so that the staff can clearly see the remaining amount of lime.

[0040] The components such as the storage pipe 101, the handle 102, the push rod 103, the plunger 104, the spring 105, the damping block 106, the connecting block 201, the diversion pipe 202, the connecting column 203, the fixed cylinder 204, the telescopic joint 205, the drainage pipe 206, the connector 207, the diversion head 208, the limit bolt 209, the positioning ring 301, and the positioning rod 302 of the present utility model are all standard components or components known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or by conventional experimental methods.
