[0026] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to detail the present application.

[0027] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the protection scope of this application.

[0028] As Figure 1 shown, this application provides a hand-pushed road rammer, including a chassis 1.

[0029] As Figure 2 shown, a driving mechanism 2 is installed on the surface of the chassis 1. The driving mechanism 2 includes an engine 21 installed on the upper surface of the chassis 1. The engine 21 is used to drive the rammer 47 to operate. A first pulley 23 is located above the chassis 1. The drive includes a transmission shaft 25 fixedly connected to the output end of the engine 21. A gearbox 22 is installed on the surface of the engine 21. A second pulley 24 is fixedly connected to the surface of the transmission shaft 25. A belt 26 is wound around the arc surfaces of the second pulley 24 and the first pulley 23. After the engine 21 is started, it drives the second pulley 24 on the transmission shaft 25 to rotate. The second pulley 24 drives the first pulley 23 to rotate through the transmission of the belt 26. The gearbox 22 is controlled by a controller 34 to control the rotation speed of the engine 21.

[0030] As Figure 2 shown, a control mechanism 3 is installed on the surface of the chassis 1. The control mechanism 3 includes a handrail 33 installed on the upper surface of the chassis 1. The handrail 33 is used to control the movement of the rammer. The control mechanism 3 includes four fixing blocks 31 fixedly connected to the surface of the chassis 1. Wheels 32 are installed on the surfaces of the fixing blocks 31. A controller 34 is fixedly connected to the surface of the handrail 33. When it is necessary to use the rammer to compact the road surface, the staff holds the handrail 33 and pushes the rammer. At this time, the wheels 32 on the fixing blocks 31 support the chassis 1 and drive the chassis 1 to move. After moving the rammer to the working position, the engine 21 is started to operate through the controller 34 on the handrail 33.

[0031] As Figure 3As shown in the figure, a ramming mechanism 4 is installed on the surface of the chassis 1. The ramming mechanism 4 includes a ramming hammer 47 installed on the lower surface of the chassis 1. The ramming hammer 47 is used for ramming the ground. The ramming mechanism 4 includes a bracket 41 fixedly connected to the upper surface of the chassis 1. A rotating shaft 42 is rotatably connected to the inner wall of the bracket 41. The rotating shaft 42 is fixedly connected to the first disc 23. Two turntables 43 are fixedly connected to the end of the rotating shaft 42. A round buckle 44 is fixedly connected to the surface of the turntable 43. The arc surface of the round buckle 44 is rotatably connected to a connecting rod 45. The end of the connecting rod 45 is rotatably connected to a moving rod 46. The moving rod 46 is slidably connected to the chassis 1. The end of the moving rod 46 is fixedly connected to the ramming hammer 47. A wear-resistant layer 48 is fixedly connected to the surface of the ramming hammer 47. The wear-resistant layer 48 is a tungsten gold plate. When the first disc 23 rotates, it drives the rotating shaft 42 in the bracket 41 to rotate, causing the turntable 43 to rotate, driving the round buckle 44 to move around the center, thereby driving the connecting rod 45 to move around the round buckle 44. When the connecting rod 45 moves around the center, it pulls the moving rod 46 to move up and down, thereby driving the ramming hammer 47 below to hammer the ground up and down to ram the ground. The tungsten gold plate of the wear-resistant layer 48 on the surface of the ramming hammer 47 has the characteristics of high strength and corrosion resistance, effectively improving the service life of the ramming hammer 47.

[0032] As Figure 4 and Figure 5As shown in the figure, a cleaning mechanism 5 is installed on the surface of the chassis 1. The cleaning mechanism 5 includes a scraper 56 installed on the surface of the chassis 1. The scraper 56 is used to clean the soil adhered to the surface of the wheel 32. A chute 51 is opened on the surface of the chassis 1. A slider 54 is slidably connected to the inner wall of the chute 51. The scraper 56 is fixedly connected to the surface of the slider 54. A first fixing hole 52 is opened in the inner wall of the chassis 1. The first fixing hole 52 communicates with the chute 51. A fixing pin 57 is slidably connected to the inner wall of the slider 54. The size of the fixing pin 57 is adapted to the size of the first fixing hole 52. The fixing pin 57 is suitable for fixing the slider 54 and the scraper 56. A pulling block 55 is fixedly connected to one end of the fixing pin 57 to facilitate pulling the fixing pin 57 to move. A second fixing hole 53 is opened in the inner wall of the chassis 1. The second fixing hole 53 communicates with the chute 51. The size of the second fixing hole 53 is adapted to the size of the fixing pin 57. A spring 58 is sleeved on the arc surface of the fixing pin 57. One end of the spring 58 is fixedly connected to the slider 54, and the other end of the spring 58 is fixedly connected to the pulling block 55. To prevent a large amount of soil from adhering to the wheel 32, the worker pulls the fixing pin 57 to move through the pulling block 55. When the rammer is not in use, the fixing pin 57 is inserted into the second fixing hole 53. The pulling block 55 is pulled out of the second fixing hole 53. At this time, the spring 58 is in a stretched state. Then, the slider 54 and the scraper 56 are moved to the first fixing hole 52. After the fixing pin 57 is aligned with the first fixing hole 52, the spring 58 contracts to drive the fixing pin 57 to insert into the first fixing hole 52 to fix the positions of the slider 54 and the scraper 56. The contracting force of the spring 58 makes the fixing pin 57 stably inserted into the first fixing hole 52.

[0033] Working principle:

[0034] When it is necessary to use the rammer to compact the road surface, the worker holds the handrail 33 and pushes the rammer. At this time, the wheel 32 on the fixed block 31 supports the chassis 1 to drive the chassis 1 to move. After moving the rammer to the working position, the engine 21 is started to run through the controller 34 on the handrail 33. After the engine 21 is started, the second pulley 24 on the transmission shaft 25 is driven to rotate. The second pulley 24 drives the first pulley 23 to rotate through the transmission of the belt 26. The gearbox 22 is controlled through the controller 34 to control the rotation speed of the engine 21.

[0035] To prevent a large amount of mud from adhering to the wheel 32, the staff member pulls the fixing pin 57 to move by means of the pulling block 55. When the rammer is not in use, the fixing pin 57 is inserted into the second fixing hole 53. When the pulling block 55 is pulled out from the second fixing hole 53, the spring 58 is in a stretched state at this time. Subsequently, the slider 54 and the scraping plate 56 are moved to the first fixing hole 52. After the fixing pin 57 is aligned with the first fixing hole 52, the spring 58 contracts to drive the fixing pin 57 to insert into the first fixing hole 52, fixing the positions of the slider 54 and the scraping plate 56. The contracting force of the spring 58 enables the fixing pin 57 to be stably inserted into the first fixing hole 52.

[0036] The first wheel disc 23 rotates, thereby driving the rotation of the rotating shaft 42 inside the bracket 41, causing the rotating disc 43 to rotate, driving the round buckle 44 to move around the center of the circle, and thus driving the connecting rod 45 to move around the round buckle 44. When the connecting rod 45 moves around the center of the circle, it pulls the moving rod 46 to move up and down, thereby driving the rammer 47 below to hammer the ground up and down to compact the ground. The tungsten plate of the wear-resistant layer 48 on the surface of the rammer 47 has the characteristics of high strength and corrosion resistance, effectively extending the service life of the rammer 47.

[0037] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
