Description

Technical Field

[0001] This utility model relates to the field of concrete compaction technology, specifically a concrete compactor. Background Art

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. It includes foundation construction, main structure construction, roof construction, decoration construction, etc. The place where construction work is carried out is called the "construction site" or "construction site". Construction uses concrete pouring and compaction equipment. In the actual concrete pouring process, due to the concentrated pouring location, the thickness of the concrete accumulation on the same area is different. Before compaction, it needs to be repeatedly leveled, which is time-consuming and labor-intensive.

[0003] A search revealed a Chinese utility model patent with publication number CN220741566U, which discloses a concrete compactor, relating to the field of concrete compaction technology. This patent describes a system consisting of a feeding box, a flattening box, and a compaction roller connected in sequence. The feeding box contains a mixing device and a feeding device, while the flattening box contains a vibrating device. A compaction plate is connected to the bottom of the vibrating device. The vibrating device includes a second motor, a turntable, and a vibrating disc. In use, concrete is pre-filled into the feeding device, poured onto a designated area, and then flattened by the flattening box connected to the feeding device. Finally, the compaction roller compacts the flattened concrete. This eliminates the need for repeated flattening, resulting in high compaction efficiency. Furthermore, the vibrating device, driven by a motor, rotates the turntable, which in turn rotates the bottom pressure rod, pre-vibrating and flattening the concrete. The high motor speed also allows for faster flattening by the compaction plate, resulting in a superior flattening effect.

[0004] However, the proposed solution (announcement number CN220741566U) has several technical problems. Firstly, soil easily adheres to the rollers or other components of the compactor during operation, increasing friction between parts and accelerating equipment wear. Secondly, residual concrete is corrosive, and long-term accumulation can corrode and damage the metal parts of the compactor, shortening its lifespan. Thirdly, operators may need to frequently stop the machine to clean the soil, which interrupts the workflow and reduces construction efficiency. To address these technical problems, this utility model proposes a concrete compactor. Summary of the Invention

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4 , the utility model provides a technical solution:

[0025] Example 1: A concrete compactor includes a top plate 1 with a square groove 2 in the center. A scraping mechanism is also provided in the center of the top plate 1. The scraping mechanism includes an electric push rod 19, a first fixed plate 20, and a scraper blade 21. One end of the first fixed plate 20 is fixedly connected to the output end of the electric push rod 19. Activating the electric push rod 19 drives the first fixed plate 20. Simultaneously, the other end of the first fixed plate 20 is fixedly connected to the top center of the scraper blade 21, linking the scraper blade 21 through the first fixed plate 20. A support frame 18 is fixedly connected to the outer diameter of the electric push rod 19, providing support. The support frame 18 is fixedly connected to the top plate 1. At the top, the scraper blade 21 is fixedly connected to two second fixing plates 22 on both sides. The top of each of the two second fixing plates 22 is fixedly connected to the middle of the top. The other ends of the two telescopic columns 23 are fixedly connected to the bottom of the top plate 1. The outer diameter of each of the two telescopic columns 23 is provided with a return spring 24, which plays the role of reset and buffer. One end of each return spring 24 is fixedly connected to the bottom of the top plate 1. The other end of each return spring 24 is fixedly connected to the top of the second fixing plate 22.

[0026] Example 2: The difference between this example and Example 1 is that a cleaning assembly is provided at the rear of the top of the top plate 1. The cleaning assembly includes a water storage tank 3, a water pump 4, and a delivery pipe 5. The input end of the water pump 4 is fixedly connected to the inside of the water storage tank 3, and the water pump 4 draws water out of the water storage tank 3. One end of the delivery pipe 5 is fixedly connected to the output end of the water pump 4, and the water pump 4 draws water out of the water storage tank 3 and sends it to the delivery pipe 5. At the same time, the other end of the delivery pipe 5 is fixedly connected to a diversion pipe 8, which can divert water. A one-way valve 6 is fixedly connected to the front of the outer diameter of the delivery pipe 5 to prevent backflow of water. A flow valve 7 is fixedly connected to the rear of the outer diameter of the delivery pipe 5 to control the water speed. A first connecting block 9 is fixedly connected to the front of the outer diameter of the diversion pipe 8, which provides support. Two first connecting columns 10 are fixedly connected to the front side wall of the first connecting block 9. The two first connecting columns 10 are fastened together, and the other ends of the two first connecting columns 10 are fixedly connected to the rear side wall of the top plate 1. They are fastened together, and multiple connecting pipes 11 are also fixedly connected to the front side of the outer diameter of the diversion pipe 8. The two connecting pipes 11 are connected together, and the other ends of the multiple connecting pipes 11 are fixedly connected to the nozzles 12. Water is sprayed onto the outer diameter of the compaction roller 17 through the nozzles 12. Four second connecting blocks 13 are arranged in a rectangular array at the bottom of the top plate 1. The second connecting blocks 13 serve as supports, and the other ends of the four second connecting blocks 13 are fixedly connected to the connecting plates 14. They are fastened together, and the opposite sides of the two connecting plates 14 are fixedly connected to the second connecting columns 15. The two connecting plates 14 are fastened together through the second connecting columns 15. The opposite sides of the two connecting plates 14 are rotatably connected to the rotating columns 16. The rotating columns 16 serve as connections, and the other ends of the two rotating columns 16 are fixedly connected to the compaction roller 17. The compaction roller 17 is used to compact the concrete.

[0027] Working principle: In actual use, the device first requires starting the electric push rod 19. The electric push rod 19 drives the first fixed plate 20 and the scraper 21 to move downwards, thereby removing residue from the outer diameter of the compaction roller 17. Simultaneously, the scraper 21 moves downwards, and the telescopic columns 23 on both sides of its top end cooperate with the return spring 24 to buffer and reset the scraper 21, reducing wear and tear on the equipment, lowering maintenance and replacement frequency, saving costs, and eliminating the need for frequent shutdowns for cleaning. This allows for continuous and efficient operation, accelerating project progress. Furthermore, if cleaning of the compaction roller 17 is required, a water pump can be started. 4. Water is pumped from the water storage tank 3 by the water pump 4 and sent to the inside of the delivery pipe 5. The one-way valve 6 on the outside of the delivery pipe 5 prevents backflow of water. At the same time, the flow rate valve 7 can be used to adjust the water flow speed inside the delivery pipe 5. After the delivery pipe 5 sends water to the inside of the diversion pipe 8, the diversion pipe 8 will spray water evenly on the outer diameter of the compaction roller 17 through multiple connecting pipes 11 and nozzles 12. This cleans up the concrete residue in time, reduces damage to the equipment, extends the normal service life of the compactor, reduces equipment replacement costs, reduces the frequency of failures caused by concrete residue, reduces maintenance frequency and costs, and improves the operating efficiency of the equipment.
