[0002] Construction engineering refers to the engineering entity formed by building various building structures and their ancillary facilities, and installing the pipelines and equipment supporting them. In the construction operation of construction engineering, it is usually necessary to use a sand and ash spreading device to lay sand and gravel on the construction road to prepare for subsequent road construction.

[0003] When the existing sand and ash spreading device levels the sand and ash on the road, the operator pushes the device to move it along the road or ground to be leveled. As the device moves forward, the leveling roller contacts and compresses the sand and ash on the ground, so as to level it evenly.

[0004] However, although the existing sand and ash spreading device can complete the leveling work of sand and ash, the traditional device cannot adjust the pressing force of the leveling roller, which results in inconsistent flattening effects in different areas, so that the flatness of the ground cannot meet the standard, and finally affects the construction quality. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a sand and ash spreading device for construction engineering, aiming to improve the problem that the pressing force of the leveling roller cannot be adjusted in the traditional device of the existing technology, which results in inconsistent flattening effects in different areas, so that the flatness of the ground cannot meet the standard.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Referring to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present utility model: a sand and ash spreading device for construction engineering, including a vehicle body 1. A mounting frame 4 is fixedly connected to the left side of the outer part of the vehicle body 1. A cylinder 5 is fixedly connected to the upper part of the mounting frame 4. The output end of the cylinder 5 is fixedly connected to a moving block 6. One end of a first adjusting plate 7 is rotatably connected to both sides of the outer part of the moving block 6. Fixed rods 9 are fixedly connected to both sides inside the mounting frame 4. Sliders 8 are slidably connected to the outer parts of the two fixed rods 9. The other ends of the two first adjusting plates 7 are rotatably connected to the upper parts of the two sliders 8. One end of a second adjusting plate 11 is rotatably connected to the lower part of each of the two sliders 8. A connecting frame 12 is arranged at the lower part of the mounting frame 4. The other ends of the two second adjusting plates 11 are rotatably connected to both sides of the upper part of the connecting frame 12. A leveling roller 13 is installed inside the connecting frame 12. A conveying pipeline 19 is fixedly connected to the upper part of the vehicle body 1. A connecting pipeline 20 is fixedly connected to the upper part of the conveying pipeline 19. A mixing box 3 is fixedly connected to the upper part of the connecting pipeline 20. Feeding ports 23 are fixedly connected to both sides of the outer part of the mixing box 3. A mixing assembly 18 is arranged on the right side of the outer part of the mixing box 3. The mixing assembly 18 is used for mixing sand and ash. A telescopic rod 14 is fixedly connected to the lower part of the mounting frame 4. The top of the telescopic rod 14 is fixedly connected to the upper part of the connecting frame 12. Through holes 10 are formed in both sides inside the mounting frame 4. The two fixed rods 9 are fixedly connected inside the two through holes 10. Mounting rods 15 are fixedly connected to both sides of the outer part of the connecting frame 12. Scrapers 16 are fixedly connected to the bottoms of the two mounting rods 15. The scrapers 16 are in contact with the outer parts of the leveling rollers 13. Crawler wheels 2 are installed on both sides of the outer part of the vehicle body 1. A handrail 24 is fixedly connected to the left side of the outer part of the vehicle body 1.

[0027] When it is necessary to adjust the compaction force of the leveling roller 13, the air cylinder 5 is started. When the air cylinder 5 is started, it drives the moving block 6 fixed to the output end to move upward. The upward movement of the moving block 6 drives the first adjusting plates 7 rotatably connected to both sides of the outside to move upward synchronously. As the two first adjusting plates 7 move, the two sliders 8 connected to the other ends thereof also move relatively along the outside of the fixed rod 9. During the movement of these two sliders 8, they simultaneously drive the two second adjusting plates 11 rotatably connected to the lower part to move relatively in opposite directions. As the second adjusting plates 11 move relatively, the connecting frame 12 connected to the other ends thereof will also move downward accordingly. The downward movement of the connecting frame 12 directly drives the leveling roller 13 installed inside to move downward, thereby adjusting the compaction force of the leveling roller 13, realizing the adjustment of the compaction force of the leveling roller 13, enabling the operator to flexibly adjust the downward pressure of the leveling roller 13 according to different construction requirements and ground conditions. Through this adjustment, the flatness and density of the ground or road surface can be ensured, and construction quality problems caused by improper compaction force can be avoided. By providing the scraping plate 16, the excess materials on the ground can be further scraped flat while the leveling roller 13 compacts the sand and ash, which helps to eliminate the unevenness on the surface and ensure that the ground is smoother and flatter, improving the construction quality. By providing the crawler wheels 2, the crawler wheels 2 provide a larger ground contact area. Compared with the traditional wheeled structure, it can better disperse the weight of the equipment during construction, increasing the stability of the equipment. Especially when operating on soft, muddy or uneven ground, the crawler wheels 2 can effectively prevent the equipment from tilting or sinking. By providing the handrail 24, the handrail 24 provides a stable gripping point for the operator. During the movement or operation of the equipment, the operator can maintain balance by grasping the handrail 24, reducing the risk of falling or injury caused by the shaking of the equipment or unexpected situations.

[0028] Refer to Figure 1 、 Figure 3 and Figure 5, the mixing component 18 includes a motor 1801 which is arranged on the outer left side of the mixing box 3. The output end of the motor 1801 is fixedly connected with a driving wheel 1802. A driven wheel 1804 is arranged outside the conveying pipeline 19. The driving wheel 1802 is connected with the driven wheel 1804 through a belt 1803. A second rotating rod 1808 is fixedly connected inside the driving wheel 1802. The second rotating rod 1808 is rotatably connected inside the mixing box 3. A first gear 1805 is fixedly connected to the outer right side of the second rotating rod 1808. Second gears 1806 are arranged on the outer right side of the mixing box 3. The first gear 1805 meshes with the two second gears 1806. First rotating rods 1807 are fixedly connected inside the two second gears 1806. Stirring rods 1809 are fixedly connected to the outer peripheries of the two first rotating rods 1807 and the second rotating rod 1808. A transmission rod 21 is fixedly connected inside the driven wheel 1804. The transmission rod 21 is rotatably connected inside the conveying pipeline 19. A spiral conveying blade 22 is fixedly connected to the outer side of the transmission rod 21. A discharge port 25 is fixedly connected to the lower right side of the conveying pipeline 19. An installation ring 17 is fixedly connected to the outer left side of the mixing box 3. The motor 1801 is fixedly connected inside the installation ring 17.

[0029] During the process of laying mortar, first, the mortar is poured into the interior of the mixing box 3 through two feeding ports 23 respectively. At this time, the motor 1801 is started. After the motor 1801 is started, the driving wheel 1802 fixedly connected to the output end starts to rotate. The driving wheel 1802 is connected to the driven wheel 1804 through a belt 1803. The rotation of the driving wheel 1802 drives the belt 1803 to transmit power, causing the driven wheel 1804 to rotate synchronously. While the driving wheel 1802 is rotating, the second rotating rod 1808 fixed inside the driving wheel 1802 also rotates accordingly. The rotation of the second rotating rod 1808 further drives the first gear 1805 fixed on its right side to rotate. As the first gear 1805 rotates, the two second gears 1806 meshing with it externally also start to rotate. The rotation of the two second gears 1806 drives the two first rotating rods 1807 fixed inside them to rotate synchronously, so that the stirring rods 1809 fixed outside the first rotating rods 1807 also rotate accordingly. At the same time, the second rotating rod 1808 itself is also fixedly connected with a stirring rod 1809. Therefore, when the second rotating rod 1808 rotates, the stirring rod 1809 fixed on it also starts to rotate, causing the stirring rods 1809 to evenly mix the mortar inside the mixing box 3. The rotation of the stirring rods 1809 ensures that there are no dead corners or uneven mixing situations during the mixing process of the mortar, so that the mortar is fully and evenly mixed inside the mixing box 3. Once the mortar is evenly mixed, through the connecting pipe 20, the mixed mortar is guided into the interior of the conveying pipe 19. During this process, the driven wheel 1804 continues to rotate and simultaneously drives the transmission rod 21 fixed inside it to rotate. The rotation of the transmission rod 21 further drives the spiral conveying blades 22 fixed outside it to start rotating. The rotating action of the spiral conveying blades 22 can effectively convey the mortar falling into the interior of the conveying pipe 19 forward, ensuring that the mortar can be smoothly conveyed to the discharge port 25. Finally, the evenly mixed mortar is discharged through the discharge port 25, completing the entire mixing, conveying, and laying process, ensuring that the mortar can be fully mixed before laying, and the mixed mortar can be more evenly distributed in the laying area, ensuring that the material composition of each part is consistent, thus forming a uniform laying layer. Such a uniform laying layer not only improves the quality of the entire construction surface but also enhances the stability and bearing capacity of the ground, ultimately improving the overall effect of road or ground construction.

[0030] Working principle: When it is necessary to adjust the compaction force of the leveling roller 13, the cylinder 5 is started. The cylinder 5 drives the moving block 6 fixed to the output end to move upward. The moving block 6 drives the first adjusting plates 7 rotatably connected to both sides of the outside to move. The two first adjusting plates 7 drive the two sliders 8 rotatably connected to the other ends to move relatively outside the two fixed rods 9. When the two sliders 8 move, they drive the two second adjusting plates 11 rotatably connected to the lower part to move relatively. The two second adjusting plates 11 move relatively and drive the connecting frame 12 rotatably connected to the other ends to move downward. The connecting frame 12 moves and drives the leveling roller 13 installed inside to move downward. By moving the leveling roller 13 downward, the compaction force can be adjusted. This realizes that the sand and ash paving equipment is convenient for adjusting the compaction force of the leveling roller 13, and can control the leveling effect according to different construction requirements and ground conditions, ensuring the flatness and density of the ground or road surface, thereby improving the overall construction quality. Then, when paving the sand and ash, first, the sand and ash are respectively poured into the inside of the mixing box 3 through the two feeding ports 23. At this time, the motor 1801 is started. The motor 1801 drives the driving wheel 1802 fixed to the output end to rotate. The driving wheel 1802 rotates and drives the driven wheel 1804 to rotate through the belt 1803. When the driving wheel 1802 rotates, it drives the second rotating rod 1808 fixed inside to rotate. The second rotating rod 1808 rotates and drives the first gear 1805 fixed to the right side of the outside to rotate. The first gear 1805 rotates and drives the second gears 1806 meshing with both sides of the outside to rotate. When the two second gears 1806 rotate, they drive the two first rotating rods 1807 fixed inside to rotate. The two first rotating rods 1807 rotate and drive the stirring rods 1809 fixed around the outside to rotate. At the same time, when the second rotating rod 1808 rotates, it drives the stirring rods 1809 fixed to the outside to rotate, mixing the sand and ash evenly. Then, it falls into the inside of the conveying pipe 19 through the connecting pipe 20. At this time, when the driven wheel 1804 rotates, it drives the transmission rod 21 fixed inside to rotate. The transmission rod 21 rotates and drives the spiral conveying blades 22 fixed to the outside to rotate. The sand and ash falling into the inside of the conveying pipe 19 are conveyed through the spiral conveying blades 22. Finally, it is discharged through the discharge port 25, realizing that when paving the sand and ash, it is convenient to mix the sand and ash, and the mixed sand and ash can be more evenly distributed in the paving area, ensuring that the material composition of each part is consistent, forming a uniform paving layer, and improving the quality and stability of the entire construction surface.
