DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The following is a description of a device for fully mixing concrete materials according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0030] like Figure 1 As shown, the device for fully mixing concrete materials according to the embodiment of the present invention may include a mixing barrel 100 , a lifting device 200 , a reciprocating lifting stirring device 300 and a tumbling device 400 .

[0031] The lifting device 200 is disposed on the mixing barrel 100 .

[0032] In one embodiment of the present invention, the lifting device 200 includes a fixing frame 210 , a driving cylinder 220 and a supporting frame 230 .

[0033] The fixing frame 210 is arranged outside the mixing barrel 100 , the driving cylinder 220 is arranged on the fixing frame 210 , and the telescopic end of the driving cylinder 220 extends vertically upward, and the supporting frame 230 is arranged on the extending end of the driving cylinder 220 .

[0034] It should be noted that a discharge port is provided at the bottom of the mixing barrel 100 for easy discharge of materials, and an electromagnetic valve is provided at the discharge port. Relevant staff can control the discharge of concrete materials in the mixing barrel 100 by opening and closing the electromagnetic valve.

[0035] The reciprocating lifting stirring device 300 is disposed on the lifting end of the lifting device 200 (i.e., on the support frame 230 and directly above the stirring barrel 100 ), and the stirring end of the reciprocating lifting stirring device 300 can be lifted and rotated in the stirring barrel 100 .

[0036] In one embodiment of the present invention, Figures 3 to 5As shown, the reciprocating lifting stirring device 300 includes a driving motor 310 , a fixing sleeve 320 , a driving shaft 330 , a rotating column 340 , a rotating shaft 350 and a stirring blade 360 ​​.

[0037] The fixing sleeve 320 is installed on the lifting end of the lifting device 200 , and the driving motor 310 is arranged on the lifting device 200 and connected to the driving shaft 330 .

[0038] The rotating column 340 is an elliptical cylinder and is slidably connected to the driving shaft 330 . The rotating column 340 can be rotatably and lifted and lowered in the fixed sleeve 320 . The rotating shaft 350 is connected to the bottom of the rotating column 340 , and the stirring blade 360 ​​is arranged on the rotating shaft 350 .

[0039] It should be noted that a slot 342 matching the size of the driving shaft 330 is formed on the rotating column 340 , and the driving shaft 330 is slidably embedded in the slot 342 .

[0040] As a possible situation of the above embodiment, an inclined annular track is provided on the inner wall of the fixed sleeve 320 , a protrusion 341 is provided on the rotating column 340 , and the protrusion 341 is slidably disposed in the annular track.

[0041] It can be understood that when the rotating column 340 rotates following the driving shaft 330, the protrusion 341 on the rotating column 340 moves along the annular track on the inner wall of the fixed sleeve 320, so that the rotating column 340 can achieve sliding separation from the driving shaft 330, so as to realize the reciprocating lifting stirring device 300, that is, it can stir in the stirring barrel 100 and can also perform lifting operations at the same time.

[0042] As a possible situation, the stirring blade 360 ​​is in an arc shape, and a plurality of protruding stirring teeth are provided on the surface of the stirring blade 360 ​​to enhance the stirring effect and shear force on the material.

[0043] It should be noted that the arc curvature radius of the stirring blade 360 ​​is 1 / 5-1 / 3 of the radius of the stirring barrel 100, and the surface of the stirring blade 360 ​​is provided with a plurality of raised stirring teeth with a height of 5-10 mm to enhance the stirring effect and shear force on the material, making the material easier to be broken up and mixed.

[0044] The tumbling device 400 can be lifted and lowered in the mixing barrel 100 to stir the material at the bottom of the mixing barrel 100 upward; and the driving end of the tumbling device 400 is connected to the output end of the reciprocating lifting mixing device 300.

[0045] In one embodiment of the present invention, Figure 2 As shown, the tumbling device 400 includes a lifting structure 410 , a transmission structure 420 and a ring plate 430 .

[0046] Among them, the lifting structure 410 is arranged on the lifting device 200, and is connected to the reciprocating lifting stirring device 300 through the transmission structure 420, the ring plate 430 is arranged at the bottom of the lifting structure 410, and the outer circle of the ring plate 430 is in contact with the inner wall of the stirring barrel 100, and the stirring end of the reciprocating lifting stirring device 300 is located in the inner circle of the ring plate 430.

[0047] As a possible scenario, a plurality of arc scrapers are provided at the bottom of the ring plate 430, and the arc scrapers form an angle of 30 to 45 degrees with the bottom surface of the ring plate 430, so that when the ring plate 430 is raised or lowered, the arc scrapers will roll the bottom material upward to prevent the material from accumulating at the bottom of the mixing barrel 100.

[0048] It should be noted that when the entire concrete mixing device is started, the reciprocating lifting mixing device 300 drives the lifting structure 410 through the transmission structure 420, so that the lifting structure 410 drives the ring plate 430 to rise and fall.

[0049] As the ring plate 430 moves up and down, its bottom moves relative to the material at the bottom of the mixing barrel 100. Since the outer ring of the ring plate 430 fits tightly against the inner wall of the mixing barrel 100, the scrapers will scoop up the material at the bottom during the rising process of the ring plate 430, and push the material originally accumulated at the bottom upward. The rising process of the ring plate 430 will cause the large-diameter aggregate, cement, water and other materials at the bottom to surge upward and enter the mixing area of ​​the mixing blade 360, and the mixing blade 360 ​​will further mix these materials evenly during the rotation and rising and falling process.

[0050] When the ring plate 430 descends, it pushes the material above downward, forming an alternating flow of materials up and down, thereby promoting the mixing of different materials.

[0051] At the same time, the stirring blades 360 of the reciprocating lifting stirring device 300 not only rotate and stir the material in the horizontal direction, but also lift and stir it in the vertical direction. This multi-dimensional stirring action, combined with the tumbling action of the ring plate 430, forms a complex flow pattern of the material in the stirring barrel 100.

[0052] For example, the stirring blades 360 stir the materials tangentially when rotating horizontally, and exchange and stir the materials in the upper and lower layers when rising and falling vertically; and the annular plate 430 stirs the bottom materials upward, forming an all-round, multi-level stirring process, ensuring that the materials can be fully mixed at various positions in the mixing barrel 100, and finally achieving full stirring of the concrete, improving the quality and performance of the concrete, ensuring the uniformity and stability of the concrete, and meeting the use requirements in different fields such as construction and road construction.

[0053] To clearly explain the above embodiment, in one embodiment of the present invention, the transmission structure 420 includes a driving wheel 331 , a driven wheel and a connecting belt.

[0054] The driving wheel 331 is arranged on the driving shaft 330 , and a groove 321 is provided on the fixing sleeve 320 . The driven wheel is connected to the input end of the lifting structure 410 . The connecting belt is connected to the driven wheel and passes through the groove 321 , and then connected to the driving wheel 331 .

[0055] It should be noted that when the driving shaft 330 starts to rotate, it drives the driving wheel 331 to rotate, so that the driving wheel 331 drives the driven wheel to rotate through the connecting belt, so that the lifting structure 410 starts.

[0056] To clearly explain the above embodiment, in one embodiment of the present invention, Figure 6 As shown, the lifting structure 410 includes a threaded sleeve 411 , a threaded rod 412 and an extension rod 413 .

[0057] The threaded sleeve 411 is embedded in the lifting device 200 , the threaded rod 412 is threadedly connected to the threaded sleeve 411 , and the extension rod 413 is arranged at the bottom of the threaded rod 412 and connected to the ring plate 430 .

[0058] It should be noted that the threaded rod 412 is a bidirectional screw. When the threaded rod 412 is a bidirectional screw, its left and right threads respectively control the up and down movement of the ring plate 430. By controlling the direction of power input (such as forward and reverse rotation of the motor), the threaded rod 412 can be rotated clockwise or counterclockwise, and then the ring plate 430 can be lifted and lowered alternately, so as to achieve flexible adjustment according to actual needs during the mixing process.

[0059] At the beginning of stirring, the material at the bottom needs to be stirred upward. At this time, the threaded rod 412 is rotated clockwise, the ring plate 430 rises, and the bottom material is pushed upward to enter the stirring area; after stirring for a period of time, if it is found that the upper material is accumulated, the threaded rod 412 can be rotated counterclockwise, the ring plate 430 can be lowered, and the upper material can be pressed downward to promote the redistribution and mixing of the material.

[0060] When the ring plate 430 moves up and down, its bottom will push the material at the bottom of the mixing barrel 100. At the same time, the stirring blades 360 of the reciprocating lifting stirring device 300 perform stirring operations in the horizontal and vertical directions. The stirring blades 360 stir and turn the material in the center area, while the ring plate 430 turns the material at the bottom and edge up and down. The two cooperate with each other.

[0061] For example, in a certain stage of mixing, the annular plate 430 rises to churn the materials, and the stirring blades 360 rotate and stir vertically, so that the materials at different positions are mixed with each other; in another stage, the annular plate 430 descends, and the stirring blades 360 adjust the stirring speed and direction, so that the materials form a more complex flow pattern. Through this coordinated work, the uniformity of the concrete material in the mixing barrel 100 is ensured, the quality and efficiency of mixing are improved, and high-quality concrete is provided for subsequent engineering applications such as construction.

[0062] In order to further improve the stability of the ring plate 430 when it is lifted or lowered, the device for fully mixing concrete materials according to the embodiment of the present invention further includes an auxiliary rod 440 .

[0063] One end of the auxiliary rod 440 is connected to the ring plate 430 , and the other end passes through the lifting end of the lifting device 200 and then extends upward.

[0064] Specifically, when the relevant staff performs the mixing operation on the concrete, first, the relevant staff puts the concrete into the mixing barrel 100 in sequence according to the preset feeding order, and then starts the driving motor 310, so that the driving motor 310 drives the driving shaft 330 to rotate accordingly.

[0065] On the one hand, the rotation of the drive shaft 330 drives the stirring blades 360 to perform conventional rotational stirring on the concrete material in the mixing barrel 100 in the horizontal direction, so that the material is preliminarily mixed and generates a certain flow; on the other hand, since the rotating column 340 is slidably connected to the drive shaft 330 and the protrusion 341 on the rotating column 340 slides in the inclined annular track of the inner wall of the fixed sleeve 320, as the drive shaft 330 rotates, the protrusion 341 drives the rotating column 340 to move up and down in the fixed sleeve 320 under the action of the annular track, so that the stirring blades 360 can achieve vertical lifting and stirring while rotating and stirring, so as to break the layered structure that may be formed by the material in the vertical direction, so that the materials at different heights can be fully contacted and mixed.

[0066] At the same time, in the transmission structure 420 , the driving wheel 331 rotates with the driving shaft 330 , and drives the driven wheel to rotate through the connecting belt, and the driven wheel further drives the lifting structure 410 to work.

[0067] In the lifting structure 410, the threaded sleeve 411 is fixed on the lifting device 200. When the driven wheel drives the threaded rod 412 to rotate in the threaded sleeve 411, the threaded rod 412 realizes lifting movement due to the action of the thread. The extension rod 413 at the bottom of the threaded rod 412 is connected to the ring plate 430, thereby driving the ring plate 430 to lift and lower in the mixing barrel 100. During the lifting process of the ring plate 430, its outer ring is tightly fitted with the inner wall of the mixing barrel 100, and the arc-shaped scraper at the bottom can effectively roll up the large-size aggregate and other materials deposited at the bottom of the mixing barrel 100. The lifting movement of the ring plate 430 cooperates with the lifting and rotating stirring action of the stirring blade 360, so that the materials at different positions in the mixing barrel 100, especially the materials at the bottom, can be fully mixed with the materials at other positions, ensuring the uniformity of the concrete during the mixing process.

[0068] During the entire mixing process, the driving cylinder 220 of the lifting device 200 can be extended and retracted according to the mixing requirements, and the height position of the reciprocating lifting mixing device 300 can be adjusted through the support frame 230 to further optimize the mixing effect and adapt to the requirements of different mixing stages and material characteristics, so that the device can efficiently and stably achieve full mixing of concrete materials and produce high-quality concrete.

[0069] In summary, according to the device for fully mixing concrete materials in the embodiment of the present invention, a complex mixing pattern is formed for the materials in the mixing barrel 100 through the coordinated work of the reciprocating lifting stirring device 300 and the tumbling device 400. The stirring blades 360 of the reciprocating lifting stirring device 300 can not only stir the materials on the horizontal plane, but also lift and stir them in the vertical direction. In conjunction with the lifting and tumbling actions of the tumbling device 400, the materials at different positions can be fully mixed, especially the materials at the bottom can be tumbled upward, so that the large-size aggregate can be evenly contacted with other materials, effectively avoiding local accumulation and stratification of the materials in the mixing barrel 100, and ensuring the uniformity of the concrete.
