[0002] "Roads" refer to highways, urban roads, and areas under the jurisdiction of a work unit where motorized vehicles are permitted, including public spaces such as plazas and public parking lots. Road engineering, on the other hand, refers to the entire process of planning, design, construction, maintenance, and management of roads, as well as the engineering entities involved. After roads are completed and put into use, damaged areas often occur, and repairing and maintaining these damaged areas is a crucial part of road construction. A common maintenance method involves filling damaged areas with cement mortar to restore them to a flat state and prevent the damage from expanding.

[0003] At present, the method of mixing cement mortar is generally that workers use handheld mixing equipment to mix cement mortar, or use fixed mixing devices to mix it. After mixing, workers need to manually discharge the mixed mortar and move it to the damaged area for pouring and filling in sequence. This method increases the fatigue of the workers.

[0004] Therefore, be necessary to provide a kind of new road construction cement mortar mixer to solve the problems of the technologies described above. Utility Model Content

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0026] See also Figures 1 to 6 The embodiment of the present invention provides a cement mortar mixer for road construction, which includes: a driving trolley 1.

[0027] In the embodiments of the present invention, please refer to Figures 1 to 6A mixing drum 2 is fixedly mounted on the driving trolley 1, and a discharge assembly 3 is provided below the mixing drum 2; the discharge assembly 3 includes a mounting frame 31, which is fixedly sleeved on the outer wall of the mixing drum 2, and a slidingly connected adapter frame 311 is inserted into the interior of the mounting frame 31, a fixedly connected spring 312 is arranged between the adapter frame 311 and the mounting frame 31, an auxiliary wheel 313 is fixedly mounted on the bottom of the adapter frame 311, and a discharge pipe 33 is fixedly mounted inside the adapter frame 311; a discharge hopper 32 is fixedly mounted inside the mounting frame 31, and a fixedly connected discharge hose 321 is arranged between the discharge hopper 32 and the discharge pipe 33.

[0028] It should be noted that: in the subsequent use process, after the cement mortar is stirred and mixed, the driving trolley 1 can be driven to move it to the desired position, and there is no need to discharge the cement mortar for secondary transportation, so that the cement mortar can be flexibly discharged at a fixed point and in a quantitative manner, thereby improving the use experience of the device. Through the setting of the auxiliary wheel 313, during use, the auxiliary wheel 33 that is against the ground can support the adapter frame 311 on its top, and at the same time, since a spring 312 is set between the adapter frame 311 and the mounting frame 1, when the auxiliary wheel 313 travels on an uneven surface When on the road surface, the adapter frame can be supported by the spring 312 to swing up and down synchronously along the road surface, so that the adapter frame 311 can synchronously support the internal discharge pipe 33, so that the discharge pipe 33 can be stably located above the road area to be repaired during discharge, thereby reducing the discharge pipe 33 from colliding with the road surface when moving to an uneven road area during the discharge process, causing discharge blockage, or the discharge pipe 33 is too far away from the road surface, causing cement mortar to splash. Therefore, the pouring accuracy of the device can be improved when discharging after the cement mortar is stirred.

[0029] In the embodiments of the present invention, please refer to Figures 1 to 6 A top cover 21 is provided on the top of the mixing drum 2, and a connected feeding hopper 211 is fixedly installed inside the top cover 21. A rotatably connected mixing rod 22 is mounted inside the top cover 21, and a fixedly connected mixing frame 221 is mounted on the outer wall of the mixing rod 22. The outer wall of the mixing frame 221 is abutted against and slidably connected to the inner wall of the mixing drum 2, and a fixedly connected mixing blade 222 is mounted on the mixing frame 221. A fixedly connected spiral blade 23 is provided below the outer wall of the mixing rod 22, and the outer wall of the spiral blade 23 is abutted against and slidably connected to the inner wall of the mixing drum 2.

[0030] It should be noted that: through the abutment between the outer wall of the mixing rack 221 and the inner wall of the mixing drum 2, the mixing rack 221 can scrape the inner wall of the mixing drum 2 when discharging the cement mortar, thereby making the discharge of the cement mortar cleaner. Through the setting of the spiral blade 23, when mixing the cement mortar, the rotating spiral blade 23 can stir the raw materials at the discharge end of the conical mixing drum 2, thereby achieving more uniform mixing of the raw materials.

[0031] In the embodiments of the present invention, please refer to Figures 1 to 6 A camera 11 is fixedly mounted on the bottom of the driving trolley 1 , a battery 12 is fixedly mounted on one side of the top of the driving trolley 1 , and a display 13 is fixedly mounted on the handle of the driving trolley 1 .

[0032] It should be noted that: through the setting of the camera 11 and the display 13, when in use, the staff can observe the image captured by the camera 11 in real time through the display 13, so that the staff can more accurately discharge the cement mortar when pouring the cement mortar;

[0033] By providing the storage battery 12 , the electrical components in the device can be powered smoothly.

[0034] In the embodiments of the present invention, please refer to Figures 1 to 6 A blocking semi-ring 24 is fixedly installed on the bottom end of the mixing drum 2, and a slidingly connected blocking plate 4 is fixedly installed on the bottom end of the mixing drum 2, and the end of the blocking plate 4 is abutted against the inner wall of the blocking semi-ring 24, and a blocking semi-ring 41 is fixedly installed on the side of the top of the blocking plate 4 away from the blocking semi-ring 24, and the end of the blocking semi-ring 41 is abutted against the end of the blocking semi-ring 24, and a cylinder 42 is fixedly installed on the top of the blocking plate 4, and a fixed bracket 43 is fixedly installed on the end of the cylinder 42, and the bottom of the fixed bracket 43 is fixedly connected to the top of the blocking semi-ring 24.

[0035] It should be noted that: through the setting of the sealing half ring 41, when the cement mortar is stirred and mixed, the sealing plate 4 located at the bottom end of the mixing drum 2 can smoothly seal the bottom end of the mixing drum 2, thereby avoiding the leakage of cement mortar from the bottom of the mixing drum 2, and thus achieving stable sealing of the mixing drum 2.

[0036] The working principle of the cement mortar mixer for road construction provided by the utility model is as follows:

[0037] When using the device, various raw materials can be adjusted into the mixing drum 2, and then the mixing rod 22 is controlled to drive the mixing blade 222 to rotate to mix the raw materials, thereby preparing the cement mortar required for road repair.

[0038] After the preparation of the cement mortar is completed, the driving trolley 1 can be controlled to move to the area where the road needs to be repaired, and then the cylinder 42 can be controlled to work to move the blocking plate 4 out of the bottom end of the unloading mixing drum 2, thereby removing the obstruction on the bottom end of the mixing drum 2. At this time, the rotating mixing rod 22 will drive the spiral blade 23 to rotate, so that the cement mortar can be discharged downward smoothly.

[0039] The cement mortar discharged downward will fall smoothly into the discharge hopper 32 below, flow into the discharge pipe 33 along the discharge hose 321 and be discharged downward through the discharge pipe 33, thereby realizing the discharge of cement mortar. In this process, the spring 312 will squeeze the adapter frame 311 through its own force, so that it drives the auxiliary wheel 313 to always be against the ground. In this process, the adapter frame 311 that telescopes up and down will drive the discharge pipe 33 to move synchronously, so that the bottom end of the discharge pipe 33 can maintain a stable height with the area of the road to be repaired, thereby reducing the phenomenon of excessive splashing of cement mortar due to the different levels of road damage during the discharge of cement mortar, thereby making the discharge of cement mortar more stable, thereby improving the user experience of this device.

[0040] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0041] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
