[0023] When the detection device detects that the accumulated height of the material reaches a preset position, the first driving member drives the first rotating shaft to rotate, and the supporting seat and the mixing barrel rotate around the first rotating shaft.

[0024] Compared with the prior art, the concrete mixing device and mixing method provided by the present application achieve at least the following beneficial effects:

[0025] The concrete mixing device provided by the present application includes a bracket, a first rotating mechanism, a mixing barrel and a mounting shaft, wherein the first rotating mechanism includes a first driving member, a support seat and a first rotating shaft, and the mixing device can rotate the mixing barrel around the first rotating shaft through the first rotating mechanism. The first driving member is connected to one end of the first rotating shaft to drive the first rotating shaft to rotate, and the first driving member can drive the first rotating shaft to rotate, because the first end of the support seat is rotatably connected to the bracket through the first rotating shaft, and the first end of the support seat is fixedly connected to the first rotating shaft, so the first rotating shaft drives the support seat to rotate relative to the bracket, and a through hole is provided at the bottom center of the mixing barrel, the first end of the mounting shaft is rotatably connected to the support seat, the second end of the mounting shaft is penetrated through the through hole and rotatably connected to the mixing barrel, and the second end of the mounting shaft is connected to the first end of the mixing shaft, and then the rotating support seat can drive the mixing barrel to rotate around the first rotating shaft, so as to avoid the concrete in the mixing barrel being concentrated at the bottom of the mixing barrel, and the concrete at the bottom can also be turned over and moved, thereby improving the mixing effect of the concrete.

[0026] In addition, the concrete mixing device further comprises a mixing shaft and a second rotating mechanism, wherein the second rotating mechanism comprises a second driving member, an outer gear ring and a driving gear, and the mixing device can rotate the mixing shaft around its axis through the second rotating mechanism. Specifically, the second driving member is connected to the second end of the second rotating shaft, and is used to drive the second rotating shaft to rotate. The second driving member can drive the second rotating shaft to rotate, because the second end of the supporting seat is rotatably connected to the bracket through the second rotating shaft, and the second end of the supporting seat and the bracket are rotatably connected to the second rotating shaft. The driving gear is installed on the first end of the second rotating shaft, so the second rotating shaft drives the driving gear to rotate, and the outer gear ring and the driving gear cooperate, and the rotating driving gear can drive the outer gear ring to rotate. The outer gear ring is arranged on the outer peripheral wall of the mixing barrel, and the outer gear ring can drive the mixing barrel to rotate around the axis of the mixing barrel. The mixing shaft is arranged in the mixing barrel and extends along the axial direction of the mixing barrel. The mixing shaft is provided with a blade group. At this time, relative to the bracket, the mixing barrel moves, and the mixing shaft is stationary. When the mixing barrel rotates, it drives the concrete inside it to move, and the blade group contacts the concrete. The blade group will exert force on the concrete and push the concrete, so that the concrete will translate and flip in the mixing barrel, thereby achieving mixing and mixing of the concrete.

[0027] The stirring device provided in this embodiment can make the stirring shaft and the stirring barrel rotate relative to each other through the second rotating mechanism, and the stirring shaft can stir and flip the concrete in the stirring barrel. Due to the effect of gravity, there is a gap between the blades at the bottom of the stirring barrel and the bottom surface of the stirring barrel, and part of the concrete in the stirring barrel will be concentrated in this part, which is difficult to fully stir, so the concrete at the bottom of the stirring barrel is fully mixed with the concrete in other parts. Taking this into account, the present application adds a first rotating mechanism, which can make the stirring barrel rotate around the axis of the first rotating shaft. During the rotation, the concrete concentrated at the bottom of the stirring barrel is flipped and moved, and then the concrete concentrated in the bottom part of the stirring barrel can be fully mixed with the concrete in other parts, thereby improving the mixing efficiency and effect of the concrete.

[0028] Of course, any product implementing the present application does not necessarily need to achieve all of the technical effects described above at the same time.

[0044] In a specific implementation, the outer gear ring 620 and the driving gear 630 are matched with helical gears.

[0045] In specific implementation, both ends of the installation shaft 500 are rotatably connected to the support seat and the mixing barrel 300 respectively through bearings. The bearings can reduce the friction between the installation shaft 500 and the hole wall of the through hole, reduce the wear of the installation shaft 500, and increase the service life of equipment parts.

[0046] During specific implementation, a sealing ring is installed in the through hole, which can reduce or even prevent the concrete in the mixing barrel 300 from leaking outward along the through hole.

[0047] In a specific implementation, the top of the mixing barrel 300 is provided with an opening, and the top opening of the mixing barrel 300 is covered with a cover body. In a specific implementation, the top of the mixing barrel 300 can be connected to the cover body through a hinge to facilitate opening and closing of the cover body; at the same time, a locking piece can also be provided on the top of the mixing barrel 300, and the cover body can be locked in the open state through the locking piece.

[0048] In specific implementation, movable rollers are provided at the bottom of the bracket 100 to facilitate the transfer and transportation of the stirring device.

[0049] During specific implementation, the first driving member 210 may be driven by manpower, electricity, hydraulic pressure, pneumatic pressure or other power methods.

[0050] The concrete mixing device provided in this embodiment includes a bracket 100, a first rotating mechanism, a mixing barrel 300 and a mounting shaft 500. The first rotating mechanism includes a first driving member 210, a support seat 220 and a first rotating shaft 701. The mixing device can rotate the mixing barrel 300 around the first rotating shaft 701 through the first rotating mechanism. Specifically, the first driving member 210 is connected to one end of the first rotating shaft 701 to drive the first rotating shaft 701 to rotate. The first driving member 210 can drive the first rotating shaft 701 to rotate because the first end 220-1 of the support seat is rotatably connected to the bracket 100 through the first rotating shaft 701, and the first end 220-1 of the support seat is fixedly connected to the first rotating shaft 701. Therefore, the first rotating shaft 701 drives the support seat 220 to rotate relative to the bracket 100, and a through hole is provided at the bottom center of the mixing barrel 300. The first end of the mounting shaft 500 is rotatably connected to the support seat, and the second end of the mounting shaft 500 is penetrated through the through hole and connected to the mixing barrel. The first end of the mixing barrel 300 is rotatably connected, and the second end of the mounting shaft 500 is connected to the first end of the mixing shaft 400, so that the rotating support seat 220 can drive the mixing barrel 300 to rotate around the first rotating shaft 701, so that the concrete deposited at one end of the mixing barrel 300 can be completely turned over, that is, the concrete originally at the bottom is at a high place after the rotation, and the concrete originally at the bottom will fall under the action of gravity and be fully turned over and mixed, so as to avoid the concrete in the mixing barrel 300 from being deposited and concentrated at the bottom of the mixing barrel 300, so that the concrete in various places can also be turned over and moved, thereby improving the mixing effect and mixing efficiency of the concrete.

[0051] In addition, the concrete mixing device also includes a mixing shaft 400 and a second rotating mechanism, and the second rotating mechanism includes a second driving member 610, an outer gear ring 620 and a driving gear 630. The mixing device can rotate the mixing shaft 400 around its axis through the second rotating mechanism. Specifically, the second driving member 610 is connected to the second end of the second rotating shaft 702, and is used to drive the second rotating shaft 702 to rotate. The second driving member 610 can drive the second rotating shaft 702 to rotate, because the second end 220-2 of the support seat is rotatably connected to the bracket 100 through the second rotating shaft 702, and the second end 220-2 of the support seat and the bracket 100 are both rotatably connected to the second rotating shaft 702, and the driving gear 630 is installed on the first end of the second rotating shaft 702, so the second rotating shaft 702 drives the driving gear 630 to rotate, and the outer gear ring 620 and the driving gear 630 cooperate, and the rotating driving gear 630 can drive the outer gear ring 620 rotates, the outer gear ring 620 is arranged on the outer peripheral wall of the mixing barrel 300, and the outer gear ring 620 can drive the mixing barrel 300 to rotate around the axis of the mixing barrel 300. The stirring shaft 400 is arranged in the mixing barrel 300 and extends along the axial direction of the mixing barrel 300. The stirring shaft 400 is provided with a blade group. At this time, relative to the bracket 100, the mixing barrel 300 moves, and the stirring shaft 400 is stationary. When the mixing barrel 300 rotates, it drives the concrete inside it to move, and the blade group contacts the concrete. The blade group will exert force on the concrete and push the concrete, so that the concrete will translate and flip in the mixing barrel 300, thereby realizing the mixing and mixing of the concrete.

[0052] The stirring device provided in this embodiment can make the stirring shaft 400 and the stirring barrel 300 rotate relative to each other through the second rotating mechanism, and the stirring shaft 400 can stir and flip the concrete in the stirring barrel 300. Due to the effect of gravity, there is a gap between the blades at the bottom of the stirring barrel 300 and the bottom surface of the stirring barrel 300, and part of the concrete in the stirring barrel 300 will be concentrated in this part, which is difficult to fully stir, so the concrete at the bottom of the stirring barrel 300 is fully mixed with the concrete in other parts. In view of this, the present application adds a first rotating mechanism, through which the stirring barrel 300 can be rotated around the axis of the first rotating shaft 701. During the rotation process, the concrete concentrated at the bottom of the stirring barrel 300 is flipped and moved, and then the concrete concentrated at the bottom part of the stirring barrel 300 can be fully mixed with the concrete in other parts, thereby improving the mixing efficiency and effect of the concrete. It should be noted that in order to avoid motion interference, these two rotations should be repeated alternately, rather than simultaneously, to achieve full stirring and mixing of the concrete. As for the duration and number of each movement, it can be set according to actual needs.

[0053] In some embodiments, the bracket 100 includes a mounting base 110, and the second driving member 610 is installed on the mounting base 110; the second driving member 610 includes a motor and a transmission assembly, and the output shaft of the motor is connected to the second rotating shaft 702 through the transmission assembly.

[0054] In this embodiment, the mounting base 110 can provide stable and reliable support for the second driving member 610 .

[0055] In a specific implementation, when the second rotating mechanism is working, the output shaft of the motor rotates and transmits the rotation to the second rotating shaft 702 through the transmission assembly.

[0056] In some embodiments, the transmission assembly includes a reducer, the output shaft of the motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the second end of the second rotating shaft 702 .

[0057] In this embodiment, the reducer can reduce the rotation speed of the output shaft of the motor so that the speed transmitted to the second rotating shaft 702 is stable and meets the rotation speed requirement of the second rotating mechanism.

[0058] In some embodiments, the transmission assembly further includes a driving pulley and a passive pulley, the driving pulley is connected to the output shaft of the reducer, the passive pulley is connected to the second end of the second rotating shaft 702, and the driving pulley and the passive pulley are connected via a transmission belt.

[0059] During specific implementation, the speed of the output shaft of the motor is decelerated by a reducer, and the output shaft of the reducer outputs the decelerated rotation, and the output shaft of the reducer drives the active pulley to rotate, and the rotating active pulley drives the passive pulley to rotate through the transmission belt, and then the passive pulley drives the second active shaft to rotate.

[0060] It should be noted that, when the stirring shaft 400 and the stirring barrel 300 rotate relative to each other through the second rotating mechanism, the outer gear ring 620 meshes with the driving gear 630, and the driving gear 630 transmits power to the outer gear ring 620, thereby driving the stirring barrel to rotate. When the mixing barrel 300 is rotated around the axis of the first rotating shaft 701 by the first rotating mechanism, the mixing barrel drives the outer gear ring 620 to rotate around the first rotating shaft 701, and the driving gear 630 is installed on the second rotating shaft 702, and the first rotating shaft 701 and the second rotating shaft 702 are coaxially arranged; that is, at this time, the outer gear ring 620 rotates around the second rotating shaft 702, and the outer gear ring 620 will move along the tangential direction when it is meshed with the driving gear 630. When the outer gear ring 620 just starts to move around the first rotating shaft 701, the driving gear 630 will likely be hit by the gear teeth of the outer gear ring 620 at the meshing point with the outer gear ring 620, resulting in a certain angle of rotation, which will likely drive the driven pulley to rotate. In general, belt transmission can mitigate impact and absorb vibration, so the driven pulley will not drive the driving pulley to rotate at a large angle, thereby protecting the motor. In other cases, even if the passive pulley drives the driving pulley to rotate at a larger angle due to the rotation of the mixing barrel 300 around the axis of the first rotating shaft 701, since the driving pulley is connected to the rotor of the motor, the rotor and the stator are not directly fixedly connected, but the rotor can pivot relative to the stator; therefore, when the passive pulley drives the driving pulley to rotate at a larger angle, the driving pulley will drive the rotor of the motor to rotate relative to the stator without motion interference.

[0061] In some embodiments, the blade assembly includes a spiral blade 410 , and the spiral blade 410 is located in the middle section of the stirring shaft 400 .

[0062] In this embodiment, the spiral blades 410 are conducive to the tumbling of the concrete in the mixing barrel 300. Specifically, when the spiral blades 410 rotate, the concrete will roll up and down like being caught in a whirlpool, so that concrete at different positions can contact and mix with each other, and finally achieve a uniform mixing effect.

[0063] In some embodiments, the blade group also includes a first blade 420 and a second blade 430, and the spiral blade 410, the second blade 430 and the first blade 420 are arranged in sequence along the direction from the middle to the end of the stirring shaft 400; the inner wall of the stirring barrel 300 is provided with a plurality of third blades 310, and the third blades 310 are close to the end face of the stirring barrel 300; the orthographic projection of the second blade 430 on the horizontal plane partially overlaps with the orthographic projection of the third blade 310 on the horizontal plane, and the first blade 420 and the second blade 430 are staggered from each other on the horizontal plane.

[0064] In this embodiment, the orthographic projection of the second blade 430 on the horizontal plane partially overlaps with the orthographic projection of the third blade 310 on the horizontal plane. When the second rotating mechanism causes the mixing shaft 400 to rotate around its own axis, the concrete located in the space between the third blade 310 and the first blade 420 can be stirred by the second blade 430; at the same time, in the first rotating mechanism, the first blade 420 and the second blade 430 are staggered with each other on the horizontal plane. In this way, when the first rotating mechanism causes the mixing barrel 300 to rotate around the first rotating axis 701, the concrete located in the space between the third blade 310 and the first blade 420 can be smoothly turned out.

[0065] In some embodiments, the concrete mixing device further includes a detection device, which is disposed on the inner wall of the mixing barrel 300 and is used to detect the deposition height of the concrete.

[0066] In specific implementation, the detection device can be set at a certain position away from the bottom surface of the mixing barrel 300 (such as one-fifth of the total height of the inner wall of the mixing barrel 300). When the height of the concrete accumulated at the bottom of the mixing barrel 300 reaches a certain position, the detection device is triggered.

[0067] Based on the same inventive concept, the present application also provides a concrete mixing method, using the concrete mixing device of any of the above embodiments. The mixing method comprises the following steps:

[0068] Step 1: Put the concrete raw materials into the mixing barrel 300;

[0069] Step 2: The second driving member drives the second rotating shaft 702 to rotate, the driving gear 630 rotates and drives the outer gear ring 620 to rotate, and the mixing barrel 300 rotates around its own axis;

[0070] Step 3: When the detection device detects that the accumulated height of the materials reaches a preset position, the first driving member drives the first rotating shaft 701 to rotate, and the supporting base 220 and the mixing barrel 300 rotate around the first rotating shaft 701 .

[0071] The stirring method provided in the embodiment of the present application has the beneficial effects of the stirring device provided in the embodiment of the present application.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
