A surveying and setting-out device for construction engineering

Abstract

This utility model discloses a surveying and setting-out device for construction engineering. A material box is fixedly connected to the middle position of the upper end of the support base. A rotating shaft is rotatably connected to the middle position inside the material box. A filter screen is fixedly connected to the upper side of the material box. A material dispersing rod is fixedly connected to the outer side of the upper part of the rotating shaft. This utility model can screen block lime powder through the function of the filter screen. The rotation of the drive motor causes the rotating shaft to drive the material dispersing rod to rotate, thereby dispersing and crushing the block lime. The rotation of the rotating shaft also causes the anti-clogging loosening tooth rod to rotate, thus enabling anti-clogging discharge when there is sufficient lime inside. When there is a small amount of lime inside, the bottom scraper can scrape off the material attached to the side wall, preventing lime from being stuck inside and unable to be discharged.

Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a measuring and setting-out device for building engineering. Background Technology

[0002] Surveying and setting out work is widely used in the construction process. Lime setting out is an important method and is commonly used in earthwork excavation, road engineering, and well construction. Lime setting out has the advantages of easy material sourcing, clear color, and no environmental pollution, making it an essential preliminary work in construction projects.

[0003] An existing surveying and setting-out device for building engineering, with publication number CN222748018U, uses a cleaning plate to sweep the ground where the setting-out is to be performed, removing dust, gravel, etc., to avoid affecting the subsequent setting-out process. It also continuously agitates the internal lime material to prevent clogging during setting-out. However, while this device continuously agitates the lime material, it cannot crush or break down lumpy lime. Consequently, the simultaneous discharge of lumpy and powdered lime can still cause blockage at the discharge port, affecting the setting-out effect. Furthermore, the device cannot control the discharge rate during setting-out, resulting in a uniform discharge speed regardless of the device's movement speed. This leads to uneven thickness of the set-out lines, hindering the uniform use of lime. Therefore, a surveying and setting-out device for building engineering is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a surveying and setting-out device for building engineering, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a measuring and setting-out device for construction engineering, comprising a support base and a fixed side plate, a material box fixedly connected to the upper middle position of the support base, a rotating shaft rotatably connected to the inner middle position of the material box, a filter screen plate fixedly connected to the upper side of the material box, the filter screen plate being rotatably connected to the rotating shaft, and a material dispersing rod fixedly connected to the outer side of the upper side of the rotating shaft. A connecting frame is sealed at the lower middle position of the material box, a guide frame is sealed at the lower end of the connecting frame, a guide wheel is rotatably connected inside the guide frame, and a discharge frame is sealed at the lower end of the guide frame.

[0006] Preferably, a fixed side plate is fixedly connected to the lower left and right sides of the support, a travel roller is rotatably connected to the lower outer side of the fixed side plate, and a control handle is fixedly connected to the upper front side of the support.

[0007] Preferably, a feed hopper is sealed to the upper left side of the material box, and a drive motor is fixedly connected to the middle position of the upper end of the material box. The output shaft of the drive motor is fixedly connected to the rotating shaft.

[0008] Preferably, a bottom scraper is fixedly connected to the lower side surface of the rotating shaft, and the bottom scraper is slidably connected to the material box.

[0009] Preferably, the lower end of the rotating shaft is fixedly connected to an anti-clogging and loosening toothed rod.

[0010] Preferably, a drive shaft is rotatably connected to the middle position of both the left and right sides of the guide frame, and the drive shaft is rotatably connected to the fixed side plate.

[0011] Preferably, a driven wheel is rotatably connected to the upper side of the inner end face of the fixed side plate, the driven wheel is fixedly connected to the transmission shaft, a transmission belt is rotatably connected to the outer side of the driven wheel, a transmission wheel is rotatably connected to the inner side of the lower end of the transmission belt, the transmission wheel is rotatably connected to the fixed side plate, and the transmission wheel is fixedly connected to the traveling roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This surveying and setting-out device for construction engineering uses a filter screen to screen block and powdered lime materials. The rotation of the drive motor causes the rotating shaft to rotate, which in turn drives the material dispersing rod to break up and crush the blocky lime materials. This prevents blockage at the discharge port when both blocky and powdered lime are discharged simultaneously. Furthermore, the rotation of the rotating shaft causes the anti-blocking loosening toothed rod to rotate, enabling anti-blocking discharge when there is sufficient lime material inside. When there is a small amount of lime material inside, the bottom scraper scrapes off the material adhering to the side walls, preventing lime material from accumulating inside and failing to discharge.

[0013] 2. The surveying and setting-out device for this construction project moves under the rolling action of the traveling rollers by pushing the control handle. At the same time, it drives the transmission wheel to rotate, which in turn drives the driven wheel to rotate. This drives the transmission shaft to rotate the guide wheel, thereby quantitatively guiding the introduced lime material downwards and discharging it evenly through the discharge frame. This ensures the uniformity of the lime setting-out and avoids the waste of excess lime material. Attached Figure Description

[0017] Example 1 Please refer to Figure 1-4 As shown, this utility model provides a measuring and setting-out device for construction engineering, including a support 1 and a fixed side plate 10. A material box 2 is fixedly connected to the middle position of the upper end of the support 1. A rotating shaft 3 is rotatably connected to the middle position inside the material box 2. A filter screen plate 4 is fixedly connected to the upper side inside the material box 2. The filter screen plate 4 is rotatably connected to the rotating shaft 3. A material dispersing rod 5 is fixedly connected to the outer side of the upper side of the rotating shaft 3. The filter screen plate 4 can screen the loaded lime material, so that the block material can be blocked at its upper end. The rotating shaft 3 can be rotated by driving the drive motor 14, so that the material dispersing rod 5 can disperse and crush the block material, so that the dispersed and crushed lime material can pass through the filter screen plate 4 and be discharged downward. A connecting frame 6 is sealed at the lower middle position of the material box 2. A guide frame 7 is sealed at the lower end of the connecting frame 6. A guide wheel 8 is rotatably connected inside the guide frame 7. A discharge frame 9 is sealed at the lower end of the guide frame 7. Powdered lime can be introduced into the guide frame 7 through the connecting frame 6. The rotation of the guide wheel 8 allows the lime to be discharged downwards quantitatively and evenly through the discharge frame 9, ensuring the uniformity of lime discharge.

[0018] Specifically, fixed side plates 10 are fixedly connected to the lower left and right sides of the support 1. The lower outer side of the fixed side plate 10 is rotatably connected to the traveling roller 11. The upper front side of the support 1 is fixedly connected to the control handle 12. By pushing the control handle 12, the traveling roller 11 can provide rolling support for the device, so as to facilitate the movement of the device.

[0019] Specifically, a feed hopper 13 is sealed and connected to the upper left side of the material box 2. The feed hopper 13 facilitates the filling and use of lime material. A drive motor 14 is fixedly connected to the middle position of the upper end of the material box 2. The output shaft of the drive motor 14 is fixedly connected to the rotating shaft 3. The rotation of the drive motor 14 can drive the rotating shaft 3 to rotate.

[0020] Specifically, a bottom scraper 15 is fixedly connected to the lower surface of the rotating shaft 3. The bottom scraper 15 is slidably connected to the material box 2. The rotation of the rotating shaft 3 enables the bottom scraper 15 to rotate, thereby preventing the material from sticking to the inner wall of the material box 2 and failing to be discharged when the amount is small.

[0021] Specifically, the lower end of the rotating shaft 3 is fixedly connected to an anti-blocking loosening toothed rod 16. The rotation of the rotating shaft 3 can drive the anti-blocking loosening toothed rod 16 to rotate, and the rotation of the anti-blocking loosening toothed rod 16 can prevent material from being squeezed and blocked when there is a large amount of material.

[0022] Specifically, a drive shaft 17 is rotatably connected to the middle of both the left and right sides of the guide frame 7. The drive shaft 17 is rotatably connected to the fixed side plate 10. A driven wheel 18 is rotatably connected to the upper side of the inner end face of the fixed side plate 10. The driven wheel 18 is fixedly connected to the drive shaft 17. A drive belt 19 is rotatably connected to the outer side of the driven wheel 18. A drive wheel 20 is rotatably connected to the inner side of the lower end of the drive belt 19. The drive wheel 20 is rotatably connected to the fixed side plate 10 and fixedly connected to the traveling roller 11. The rotation of the traveling roller 11 can drive the drive wheel 20 to rotate, thereby driving the driven wheel 18 to rotate, which in turn drives the drive shaft 17 to rotate the guide wheel 8, thus quantitatively guiding the introduced lime material downwards.

[0023] Working Principle: This utility model is a surveying and setting-out device for construction engineering. When conducting surveying and setting-out work in construction projects, lime material is first loaded into the material box 2 through the feed hopper 13. The filter screen 4 screens the lime material, preventing lumps from forming at the top. The drive motor 14 rotates the rotating shaft 3, causing the dispersing rod 5 to break up and crush the lumps. The crushed lime material then passes through the filter screen 4 and is discharged downwards. The rotation of the rotating shaft 3 simultaneously drives the bottom scraper 15 and the anti-clogging toothed rod 16 to rotate. The rotation of the anti-clogging toothed rod 16 prevents material from clogging when there is a large quantity of material. The rotation of the bottom scraper 15 prevents the material from sticking to the inner wall of the hopper 2 and failing to discharge when the quantity is small, thus ensuring the smooth discharge of the lime material. After the lime material enters the guide frame 7 through the connecting frame 6, the push of the control handle 12 causes the traveling roller 11 to rotate, enabling the entire device to move quickly. Simultaneously, the rotation of the traveling roller 11 drives the transmission wheel 20 to rotate, which in turn drives the driven wheel 18 to rotate, thereby causing the transmission shaft 17 to drive the guide wheel 8 to rotate. This allows the introduced lime material to be quantitatively guided downwards and evenly discharged through the discharge frame 9, ensuring the uniformity of the lime discharge line and preventing waste of excess lime material due to slow or stopped device movement.
