DETAILED DESCRIPTION

[0015] In order to make the technical scheme of the present application clearer, the present application will be further described in detail below in combination with the drawings and specific embodiments. EMBODIMENT

[0016] As shown in Figure 1 , the lower surface of the stirring drum 1 is fixedly connected with the support leg 11; The plurality of support legs 11 arranged can not only enhance the stability of the device, reduce the shaking and displacement during stirring operation, and ensure the stirring quality, but also improve the operation safety, avoid the risk of device tipping, facilitate flexible arrangement during construction, adapt to different construction environments, and increase the applicability of the device.

[0017] As shown in Figure 1-Figure 5 , the lower surface of the stirring drum 1 is fixedly connected with the support leg 11;As shown, a mixing device for construction construction is provided, comprising a mixing drum 1, a mixing chamber 2 is integrally formed on the upper surface of the mixing drum 1, a sealing cover plate 3 is fixedly connected to the upper surface of the mixing drum 1 by a plurality of bolts, a control box 4 is fixedly connected to the upper surface of the sealing cover plate 3, a feed port 5 is fixedly connected to the upper surface of the sealing cover plate 3 and located on the right side of the control box 4, and a discharge pipe 6 is integrally formed below the outer wall of the mixing drum 1; a hollow rod 7 is provided inside the control box 4, a rotating rod 8 is sleeved inside the hollow rod 7, the bottom end of the hollow rod 7 extends to the inside of the mixing chamber 2, the bottom end of the rotating rod 8 extends to the bottom of the hollow rod 7, a plurality of mixing blades 9 are fixedly connected to the outer wall of the hollow rod 7 and located inside the mixing chamber 2, and a plurality of mixing blades 10 are fixedly connected to the outer wall of the rotating rod 8 and located below the hollow rod 7; When the stirring device is in use, the building materials to be mixed are put into the material feed port 5, and the materials enter the stirring chamber 2 through the material feed port 5. After starting the device, the control box 4 controls the operation of the hollow rod 7 and the rotating rod 8. The hollow rod 7 drives the multiple stirring blades 9 located in the stirring chamber 2 to rotate, and the rotating rod 8 drives the multiple stirring blades 2 10 below its outer wall to rotate. The two cooperate to fully stir the materials, and after the stirring is completed, the materials are discharged through the discharge pipe 6. Therefore, the double-layer stirring of the stirring blades 1 9 and the stirring blades 2 10 can make the materials mixed more evenly and improve the stirring quality. The sealing cover plate 3 ensures that the materials will not spill during the stirring process, reducing waste and pollution, and improving the construction efficiency as a whole.

[0018] like Figure 1 、 Figure 2 and Figure 4 As shown, the inner upper surface of the control box 4 is fixedly connected to the control motor 12, the bottom end of the output shaft of the control motor 12 is fixedly connected to the top of the rotating rod 8, the outer wall of the rotating rod 8 and located above the hollow rod 7 is fixedly connected to the bevel gear 13, the top of the hollow rod 7 is fixedly connected to the bevel gear 2 14, the inner left side of the control box 4 is rotatably connected to the connecting rod 15 through the rotating shaft, the right end of the connecting rod 15 is fixedly connected to the bevel gear 3 16, and the outer walls of the bevel gear 3 16 are respectively meshed with the outer walls of the bevel gear 13 and the bevel gear 2 14; When the device starts, the control motor 12 starts to work, and the output shaft bottom end drives the rotating rod 8 fixedly connected therewith to rotate. When the rotating rod 8 rotates, the bevel gear one 13 fixedly connected to the outer side wall above the hollow rod 7 rotates. Since the bevel gear three 16 is rotatably connected to the left side inside the control box 4 through the connecting rod 15, and the outer side wall thereof is engaged with the bevel gear one 13 and the bevel gear two 14 respectively, the bevel gear one 13 drives the bevel gear three 16 to rotate, thereby driving the bevel gear two 14 engaged with the bevel gear three 16 to rotate in the opposite direction. Since the bevel gear two 14 is fixedly connected to the top end of the hollow rod 7, the hollow rod 7 rotates in the opposite direction with the bevel gear two 14, and finally the plurality of stirring blades one 9 on the hollow rod 7 and the plurality of stirring blades two 10 on the rotating rod 8 rotate in the opposite direction, so that the materials in the stirring cavity 2 are subjected to different forces, forming a stronger convection and shear effect, so that the materials are mixed more uniformly and sufficiently, greatly improving the stirring efficiency and quality, while reducing the residence phenomenon of the materials in the stirring process, reducing the stirring dead angle, and further ensuring the completeness of the stirring.

[0019] As shown in Figure 2 and Figure 5 , the inner lower surface center of the stirring cavity 2 is rotatably connected with the movable circular plate 17, the upper surface center of the movable circular plate 17 is fixedly connected with the plug-in plate 18, the lower surface center of the rotating rod 8 is provided with the positioning groove 19, and the top end of the plug-in plate 18 extends into the inside of the positioning groove 19. When the device works, the rotating rod 8 rotates, the positioning groove 19 at the lower surface center thereof cooperates with the plug-in plate 18 fixedly connected to the upper surface center of the movable circular plate 17, and plays a precise positioning role on the rotating rod 8, so as to ensure that the rotating rod 8 always maintains a stable shaft center during high-speed rotation, avoiding shaking to affect the stirring effect of the stirring blades two 10. When it is necessary to clean the stirring device, since the plug-in plate 18 is in plug-in cooperation with the positioning groove 19, only the plurality of bolts fixedly connecting the sealing cover plate 3 need to be disassembled, and the sealing cover plate 3 is taken out upward. At this time, the rotating rod 8 is taken out together with the sealing cover plate 3, and the hollow rod 7, the stirring blades one 9, the rotating rod 8 and the stirring blades two 10 and other components are completely exposed, so that the staff can clean them thoroughly. Therefore, not only the stability and efficiency of the stirring work are ensured through positioning, but also the disassembly and cleaning process is greatly simplified, the cleaning time and labor cost are saved, the device is kept clean, the service life is prolonged, and the device is kept clean.

[0020] As shown in Figure 1 , the front of the discharge pipe 6 is provided with a switch handle 28. By rotating the switch handle 28, the on-off and discharge speed of the discharge pipe 6 can be directly controlled, so that the material is smoothly discharged from the discharge pipe 6, and the construction efficiency is improved. In addition, the switch handle 28 of the mechanical structure is strong in durability and is not easy to be damaged by material impact or environmental factors, thereby reducing the maintenance cost. The switch handle 28 is compatible with the overall design of the device, and further improves the practicality of the stirring device.

[0021] As shown in Figure 2 , Figure 4 and Figure 5 , the hollow rod 7 is fixedly connected with a fixed ring 22 above the outer side wall, the outer side wall of the fixed ring 22 is fixedly connected with a fixed rod 23, the opposite ends of the two fixed rods 23 are fixedly connected with scrapers 24, the opposite sides of the two scrapers 24 are fixedly connected with fixed rods 25, the bottom end of the rotating rod 8 is rotatably connected with a movable ring 26 through a rotating shaft, and the opposite ends of the two fixed rods 25 are fixedly connected with the outer side wall of the movable ring 26. When the hollow rod 7 rotates, the fixed ring 22 will rotate synchronously, the fixed ring 22 drives the symmetrically connected fixed rod 23 to rotate, and the fixed rod 23 opposite end of the scraper 24 is tightly attached to the inner side wall of the stirring chamber 2 to rotate synchronously, at the same time, the fixed rod 25 at the opposite side of the scraper 24 drives the movable ring 26 rotatably connected with the bottom end of the rotating rod 8 through the rotating shaft to rotate, ensuring that the scraper 24 always maintains a stable scraping posture during rotation. The scraper 24 can continuously scrape the material adhering to the inner side wall of the stirring chamber 2, avoiding the difficulty of cleaning the material after long-term residue hardening, ensuring the effective volume of the stirring chamber 2 is not occupied, reducing material waste, and making the material mixing more uniform to improve the stirring quality. In addition, the simultaneous scraping action with stirring does not require additional operation, simplifying the equipment maintenance process, reducing the cost of manual cleaning, and prolonging the service life of the stirring chamber 2.

[0022] As shown in Figure 4 , the outer side wall of the connecting rod 15 is sleeved with a support ring 27, and the outer side wall of the support ring 27 is fixedly connected with the upper surface of the sealing cover plate 3. The support ring 27 can effectively limit the radial shaking of the connecting rod 15, ensuring that it always maintains a stable rotating track, avoiding the deviation of the meshing of the bevel gear 13, the bevel gear 14 and the bevel gear 16 caused by the shaking of the connecting rod 15, thereby ensuring the transmission accuracy of the hollow rod 7 and the rotating rod 8, making the reverse rotation of the stirring blade 9 and the stirring blade 10 more stable and reliable, and further improving the running stability and durability of the entire stirring device.

[0023] As shown in Figure 1 and Figure 3As shown, the rear surface of the control box 4 is fixedly connected with an access plate 20 by a plurality of bolts, and the front surface of the control box 4 is provided with a control button 21; By unscrewing the multiple bolts on the outside of the inspection plate 20, the inspection plate 20 can be removed, and the internal components can be directly accessed for inspection and maintenance without disassembling the control box 4 as a whole, which greatly shortens the inspection time and reduces the difficulty of maintenance. At the same time, the control button 21 integrates the start, stop, speed adjustment and other functions of the device. By pressing different control buttons 21, the operator can intuitively and quickly control the operating status of the stirring device without complicated operating procedures. This not only improves the convenience of operation, but also can adjust the parameters in time according to the stirring requirements of the material to ensure the stirring effect. At the same time, the clear button markings also reduce the risk of misoperation and improve the safety of the device operation.

[0024] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
