Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a line-laying and ash-scattering device for engineering surveying. Background Art

[0002] Before construction begins, the site needs to measure and divide the area according to the planning drawings. When laying out and measuring on the site, white lime is spread to help mark and determine the location of the measurement points. During the construction of a building, the location and size of the foundation need to be determined. Spreading white lime can help workers accurately mark the boundaries and center points of the foundation for subsequent construction.

[0003] In the actual ash spreading process, it is often necessary to refer to the drawings, that is, the ash spreading device needs to stop frequently. The existing line-laying ash spreading device will continue to spread ash at the same place when it stops. The ash spreading outlet of the line-laying ash spreading device needs to be manually closed to stop the ash spreading, which undoubtedly causes the problem of troublesome operation. Utility Model Content

[0004] The utility model aims to overcome the defects of the prior art, provide a line-laying and ash-scattering device for engineering surveying, and solve the problem that the line-laying and ash-scattering device in the prior art cannot automatically stop ash-scattering.

[0008] After the ash-spreading trolley moves, the rear driving wheel drives the discharging wheel to rotate in the bottom hole of the aggregate assembly, and the white ash inside the aggregate assembly is brought out through the storage trough opened on the discharging wheel, thereby realizing automatic ash-spreading when the ash-spreading trolley moves.

[0009] By adopting this technical solution, the discharging wheel is coaxially connected with the rear driving wheel of the ash-spreading trolley. When the ash-spreading trolley moves, the discharging wheel can rotate along with the rear driving wheel, and the white ash inside the aggregate assembly is brought out through the circumferentially opened storage trough, thereby realizing the corresponding ash-spreading operation; when the ash-spreading trolley stops moving, the rear driving wheel stops rotating, and the discharging wheel is in a stationary state at this time, which will hinder the white ash inside the aggregate assembly from falling, and the ash-spreading will be automatically stopped, thereby realizing automatic control of the ash-spreading, reducing the difficulty of the ash-spreading operation, and there will be no problem of uneven ash-spreading caused by continuous ash-spreading after the ash-spreading trolley stops moving.

[0010] Furthermore, the ash spreading trolley comprises a frame, a handlebar, a rear driving wheel, a front steering wheel and an indication assembly;

[0018] Furthermore, the aggregate assembly includes a box body and a box cover, the box body is fixed on the frame, and the box cover is connected to the top of the box body.

[0019] By adopting this technical solution, the aggregate assembly is configured as two parts, a box body and a box cover, and the box cover can be removed to facilitate the dust filling operation inside the box body.

[0020] Furthermore, the discharging assembly further comprises a shell, a mounting ring and a rotating shaft, wherein holes are opened on the upper and lower sides of the shell;

[0021] The discharging wheel is rotatably connected to the interior of the housing through the mounting ring;

[0022] The discharging wheel is coaxially connected with the rear driving wheel through the rotating shaft.

[0023] By adopting this technical solution, a mounting ring is provided to increase the stability of the discharging wheel rotating inside the shell; and a rotating shaft is provided to realize the coaxial connection between the discharging wheel and the rear driving wheel.

[0024] Furthermore, a material control assembly is provided at the bottom of the shell, and the material control assembly includes a discharge box, a baffle, a threaded sleeve and a bidirectional screw;

[0025] The discharge box is connected and communicated with the bottom hole of the shell; the baffle is symmetrically slidably connected to the bottom of the discharge box; the threaded sleeve is fixed on the baffle; the two ends of the bidirectional screw are respectively threadedly matched with the two threaded sleeves on the two baffles that are symmetrically arranged;

[0026] The two symmetrically arranged baffles can be driven to move simultaneously by rotating the bidirectional screw, so as to change the distance between the two symmetrically arranged baffles.

[0027] By adopting this technical solution, a material control component is added to the bottom of the shell to control the ash output. Specifically, after rotating the bidirectional screw, the distance between the two baffles can be changed through the cooperation of the bidirectional screw and the threaded sleeve. The distance is actually the width of the ash outlet, so as to control the ash output and adapt to the ash output needs under different conditions.

[0028] Furthermore, the material control assembly also includes a limit block, which is connected to any end of the bottom of the discharge box to limit the movement of the baffle at the corresponding end.

[0029] By adopting this technical solution, a limit block is set to limit the movement of the baffle, so as to prevent the baffle from moving too far and causing it to detach from the bottom of the discharge box.

[0030] Compared with the prior art, the utility model has the following beneficial effects:

[0031] 1. The ash spreading is controlled by setting a discharging wheel coaxially connected to the rear driving wheel of the ash spreading trolley. The discharging wheel can spread the ash normally as the ash spreading trolley moves, and can also block the ash spreading when the ash spreading trolley stops moving, thereby realizing automatic control of the ash spreading and reducing the difficulty of laying out the ash.
