Description

Technical Field

[0001] The utility model belongs to the technical field of raw material mixers, and particularly relates to a raw material mixer for a paving foundation in road construction. Background Art

[0002] The paving foundation for road construction generally uses concrete. When mixing concrete, a mixer is required. The utility model patent with the patent authorization announcement number CN221365228U discloses a mixer for concrete, including a housing. Two feeding ports are communicated with the top wall of the housing. A motor fixedly connected to the housing is arranged between the two feeding ports. The output end of the motor penetrates into the interior of the housing. A stirring roller is fixedly connected to the output end of the motor. A first connecting wheel is sleeved on the surface of the output end of the motor. A second connecting wheel is fixedly connected to the top wall of the housing. A belt is sleeved on the surfaces of the first connecting wheel and the second connecting wheel. By setting a buffer unit in the utility model, for the vibration generated during the operation of the housing, the buffer sleeve slides on the sliding rod by using the damping rod. When the buffer sleeve slides, it will be blocked by the spring to play a buffering role. At the same time, the buffer rod slides in the air chamber through the rubber ring, and the gas inside the air chamber will be discharged during the sliding process to achieve a secondary buffering effect. In this way, it will not increase the personnel usage cost and is also convenient for personnel to use. However, when the mixer in the prior art is in use, the materials inside the device are not mixed evenly enough, which affects the use effect of the concrete. At the same time, the concrete discharge is not complete and fast enough. Summary of the Invention

[0003] The purpose of the utility model is to provide a raw material mixer for a paving foundation in road construction, which solves the problems that when the existing raw material mixer for a paving foundation in road construction is in use, the materials inside the device are not mixed evenly enough, affecting the use effect of the concrete, and the concrete discharge is not complete and fast enough.

[0004] To achieve the above purpose, the utility model provides a raw material mixer for a paving foundation in road construction, including a bottom plate. An adjusting mechanism is arranged on the bottom plate. A mixing barrel is arranged on the adjusting mechanism. The outer side of the mixing barrel is installed with a support plate through a bearing. An end cover is arranged on the outer side of the left end of the mixing barrel. A barrel cover is fixedly connected to the right end of the mixing barrel. A stirring mechanism is arranged on the barrel cover.

[0005] The principle of the present utility model is as follows: During use, raw materials are fed into the interior of the mixing cylinder from the discharge end, and then the end cover is closed. The motor is started, and the motor drives the main shaft to rotate. The main shaft drives the sliding cylinder to rotate, the sliding cylinder drives the connecting rod to rotate, and the connecting rod drives the scraping blade to rotate, so that the scraping blade stirs the raw materials in the mixing cylinder. Then the hydraulic cylinder is started, and the hydraulic cylinder drives the sliding pin to move. The sliding pin drives the turntable to move, the turntable drives the sliding cylinder to move, and the sliding cylinder drives the connecting rod to move. Thus, while the scraping blade moves, it rotates and stirs the raw materials. By driving the main shaft to rotate through the motor, the sliding cylinder is driven to rotate, and then the scraping blade rubs against the inner wall of the mixing cylinder, stirring the materials. And by driving the sliding cylinder to reciprocate through the air cylinder, the scraping blade moves left and right in the mixing cylinder to stir, making the raw materials more evenly stirred. When discharging, the end cover is opened, and then the air cylinder is started. The air cylinder drives the sliding plate to slide on the bottom plate, thereby causing the adjusting rod to deflect, and then causing the angle of the mixing cylinder to change, making the discharging of the device more efficient and rapid, and making the discharging in the mixing cylinder more complete.

[0006] The beneficial effects of the present utility model are as follows: By driving the sliding plate to slide on the bottom plate through the air cylinder, the adjusting rod is deflected, and then the angle of the mixing cylinder is changed, making the discharging of the device more efficient and rapid, and making the discharging in the mixing cylinder more complete.

[0007] By driving the main shaft to rotate through the motor, the sliding cylinder is driven to rotate, and then the scraping blade rubs against the inner wall of the mixing cylinder, stirring the materials.

And by driving the sliding cylinder to move through the air cylinder, the spiral conveyor blade is moved to rotate inside the discharge end of the mixing cylinder, further improving the discharging efficiency of the materials and avoiding stuck discharging.

[0008] Furthermore, the adjusting mechanism includes a support rod. The support rod is fixedly connected to the bottom plate, and the support rod is hinged to the support plate.

By driving the sliding plate to slide on the bottom plate through the air cylinder, the adjusting rod is deflected, and then the angle of the mixing cylinder is changed, making the discharging of the device more efficient and rapid, and making the discharging in the mixing cylinder more complete.

[0009] Furthermore, the lower end of the sliding plate is fixedly connected with a dovetail block. A dovetail groove is formed in the upper end of the bottom plate. The dovetail groove is slidably connected with the dovetail block. By providing the cooperation of the dovetail block and the dovetail groove, the movement of the sliding plate is guided.

A sliding cylinder is slidably connected to the outside of the main shaft. A connecting rod is fixedly connected to the outside of the sliding cylinder. The end of the connecting rod is fixedly connected to a scraping blade. The scraping blade is slidably connected to the stirring cylinder. A turntable is fixedly connected to the outside of the sliding cylinder. A hydraulic cylinder is fixedly installed above the motor at the right end of the cylinder cover. The output end of the hydraulic cylinder penetrates through the cylinder cover and is slidably connected to the cylinder cover. A spiral conveyor blade is arranged on the outside of the sliding cylinder. The motor drives the main shaft to rotate, thereby causing the sliding cylinder to rotate, and further causing the scraping blade to scrape against the inner wall of the stirring cylinder, turning over and stirring the materials. The cylinder drives the sliding cylinder to reciprocate, thereby causing the scraping blade to move left and right in the stirring cylinder for stirring, making the raw materials more evenly stirred. And the cylinder drives the sliding cylinder to move, thereby causing the spiral conveyor blade to move into the discharge end of the stirring cylinder and rotate, further improving the material discharge efficiency and avoiding material discharge jams.

[0012] Furthermore, a guide block is welded inside the sliding cylinder, and a guide groove is formed on the outside of the main shaft. The guide groove is slidably connected to the guide block.
