Multi-axis hybrid mixing equipment for concrete pouring

Abstract

The present invention relates to the technical field of mixing equipment, and discloses a multi-axis hybrid mixing equipment for concrete pouring. The present invention solves the problem that stones are prone to accumulate near the inner wall during the mixing process, resulting in uneven mixing of materials and reducing their quality. The driving mechanism rotates itself to mix the concrete in the mixing drum, and at the same time drives the outer plate member and the inner plate member to rotate. When the outer plate member and the inner plate member move to the convex part, the outer plate member and the inner plate member are in the same horizontal state and rotate on their own, pushing the stones accumulated near the inner wall of the mixing drum into the main mixing flow near the driving mechanism. When the outer plate member and the inner plate member move to the arc part, the outer plate member and the inner plate member gradually change from the same horizontal state to a mutually perpendicular state and rotate on their own. When the outer plate member and the inner plate member move to the concave part, the outer plate member and the inner plate member are in a mutually perpendicular state and rotate on their own, stirring and mixing the accumulated stones pushed back, avoiding the easy accumulation of stones near the inner wall, resulting in uneven mixing of materials.

Description

Technical Field

[0001] The present invention relates to the technical field of mixing equipment, specifically a multi-axis hybrid mixing equipment for concrete pouring. Background Art

[0002] Concrete mixing equipment is a mechanical device used to mix cement, sand and gravel with water to form concrete mixture, which is widely used on construction sites. Using a mechanized concrete mixer to mix cement can save a large amount of manpower and material resources.

[0003] Common existing concrete mixing equipment is usually single-axis forced mixing. Although it is an improvement compared to manual mixing, there are mixing dead zones during use. The materials in the mixing drum cannot be fully turned over in all directions, and it is easy for some materials to be unevenly mixed, resulting in instability in performance indicators such as the strength and workability of the finally produced concrete, and it cannot meet the growing demand for high-quality concrete in large-scale construction projects.

[0004] For example, a Chinese patent with the publication number CN110978277B discloses a concrete mixing equipment. By starting the forward rotation of the motor to drive the rotation of the driving shaft, the driving shaft drives the mixing fan blades and the mixing arms to rotate, and mix the concrete in the concrete mixing tank. Since the driving shaft is located at the center of the concrete mixing tank, and the mass of the stones in the concrete is much larger than that of the cement and sand, it makes the stones easy to accumulate near the inner wall of the concrete mixing tank during the mixing process, resulting in the materials in the mixing drum not being fully turned over in all directions, and some materials being unevenly mixed, making it difficult to ensure the quality of the concrete.

[0005] Therefore, a multi-axis hybrid mixing equipment for concrete pouring is needed. Summary of the Invention

[0006] In order to solve all or part of the above problems, the purpose of the present invention is to provide a multi-axis hybrid mixing equipment for concrete pouring to solve the problem that the stones are easy to accumulate near the inner wall during the mixing process in the above-mentioned prior art, resulting in uneven mixing of materials and reducing their quality.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A multi-axis hybrid mixing equipment for concrete pouring, including a mixing drum, a multi-axis mixing assembly is arranged inside the mixing drum. The multi-axis mixing assembly includes a driving mechanism, and stirring mechanisms are symmetrically arranged on both sides of the driving mechanism. A driven disk is installed inside the mixing drum, and a track is fixedly installed at the lower end of the driven disk;

[0008] The driving mechanism includes a servo motor fixedly connected to the outer surface of the mixing drum, and the output end of the servo motor penetrates the mixing drum and is fixedly installed with a rotating shaft;

[0009] The stirring mechanism includes a telescopic member fixedly connected to the driving mechanism. One end of the telescopic member is rotatably installed with an outer plate member, and the inner side of the outer plate member is rotatably installed with an inner plate member. The track includes a plurality of convex portions, and both ends of the convex portion are fixedly connected with arc portions. One end of the arc portion away from the convex portion is fixedly connected with a concave portion. A tooth group is fixedly arranged on the outer surface of the track, and both the outer plate member and the inner plate member are meshed and connected with the tooth group;

[0010] On the upper surface of the driven disk, a tooth track five is fixedly installed. On the outer side of the rotating shaft, a quarter bevel gear is fixedly installed. Inside the mixing drum, a transmission member is arranged. The transmission member includes two groups of suspension rods fixedly connected to the inner wall surface of the mixing drum. A transmission rod is installed through the inside of the suspension rods, and the transmission rod is rotatably connected to both groups of suspension rods. One end of the transmission rod is fixedly installed with a bevel gear, and the bevel gear is meshed and connected with the quarter bevel gear. The other end of the transmission rod is fixedly installed with a gear three, and the gear three is meshed and connected with the tooth track five.

[0011] Furthermore, the driving mechanism includes a servo motor fixedly connected to the outer wall surface of the mixing drum. The output end of the servo motor penetrates through the mixing drum and is fixedly installed with a rotating shaft. The lower end of the rotating shaft is fixedly installed with a rotating disk, and the lower end of the rotating disk is fixedly installed with a stirring rod. On the outer side of the stirring rod, multiple groups of stirring blades are symmetrically and fixedly installed. By driving the rotating shaft to rotate through the servo motor, the rotating shaft drives the rotating disk and the stirring rod to rotate, so that multiple groups of stirring blades rotate around the axis of the stirring rod, thereby efficiently stirring and mixing the concrete.

[0012] Furthermore, the tooth group includes a tooth track one fixedly installed on the surface of the track, a tooth track two fixedly installed on the surface of the convex portion, a tooth track three fixedly installed on the surface of the arc portion, and a tooth track four fixedly installed on the surface of the concave portion;

[0013] The outer plate member includes a connecting rod one and a gear one located at the upper end of the connecting rod one and fixedly connected thereto. On the outer side of the connecting rod one, two groups of frame plates are symmetrically and fixedly installed. On one side where the two groups of frame plates are close to each other, a sleeve is fixedly installed. A cavity is reserved between the two groups of frame plates;

[0014] The inner plate member includes a connecting rod one that runs through and a connecting rod two that is rotatably connected. A gear two is fixedly installed at the upper end of the connecting rod two, and the lower end of the connecting rod two is rotatably connected to a sleeve. Fixing plates are symmetrically and fixedly installed on the outer side of the connecting rod two, and the two groups of fixing plates fit with the cavity. During the movement of the outer plate member, the gear one and the tooth rail one are in a meshed state throughout the process. When the outer plate member and the inner plate member move to the convex part position, the gear two and the tooth rail two are engaged. At this time, since the teeth of the tooth rail one and the tooth rail two correspond one by one, the gear one and the gear two rotate synchronously, and thus the two groups of fixing plates fill the cavity, preventing stones from passing through and pushing the stones away from the vicinity of the inner wall of the mixing drum. When the outer plate member and the inner plate member move to the arc part position, the gear two ends its meshing connection with the tooth rail two, and then engages with the tooth rail three. During the subsequent meshing process, the rotation speed of the gear two is higher than that of the gear one until the gear two ends its meshing with the tooth rail three. During this same stroke process, since the number of teeth of the tooth rail three is one - quarter more than that of the tooth rail one, the gear two rotates 90° more than the gear one, making the outer plate member and the inner plate member in a mutually perpendicular state as a whole. Then the outer plate member and the inner plate member move to the concave part position, and the gear two engages with the tooth rail four. At this time, since the teeth of the tooth rail one and the tooth rail four correspond one by one, the gear one and the gear two rotate synchronously, and the cavity is in an open state, enabling the frame plate and the fixing plates to stir and mix the accumulated stones, and the stones can pass through the cavity, thereby increasing the irregular movement of the stones and improving the mixing effect. When the outer plate member and the inner plate member move to the arc part position again, the gear two rotates 90° more than the gear one again. When the outer plate member and the inner plate member move to the convex part position again, the gear one and the gear two rotate synchronously and the two groups of fixing plates fill the cavity. Repeating like this, on the one hand, it can effectively prevent stones from accumulating near the inner wall, resulting in uneven mixing of materials. On the other hand, it can stir and mix the accumulated stones one step ahead, enabling the stones to better re - integrate into the main mixing stream, improving the mixing effect and the mixing efficiency.

[0015] Further, the telescopic member includes a cavity rod fixedly connected to the lower surface of the rotating disk. A spring is fixedly installed on the inner wall surface of the cavity rod, and one end of the spring is fixedly installed with a telescopic rod. One end of the telescopic rod is rotatably connected to the connecting rod one. During the rotation of the rotating disk, the cavity rod is driven to rotate around the axis of the rotating disk, and then the outer plate member and the inner plate member are driven to rotate around the axis of the rotating disk. Through the setting of the spring and the telescopic rod, while not affecting the self - rotation of the outer plate member, it can form an adaptive compensation for the difference between the distance from the convex part to the axis of the rotating disk and the distance from the concave part to the axis of the rotating disk, thus achieving the multi - axis mixing and stirring effect of the concrete.

[0016] Further, the two groups of stirring mechanisms have the same structural composition.

[0017] Further, the sleeve is movably connected to the inner bottom surface of the mixing drum, ensuring the stable meshing state of the first gear and the first toothed rail without affecting the rotation of the outer plate member, thereby guaranteeing the efficient mixing of concrete.

[0018] Further, the driven disk is rotatably connected to the inner surface of the mixing drum. On the one hand, it can relieve the pressure on the output end of the servo motor, thereby extending its service life. On the other hand, it can improve the overall stability of the device during operation to ensure the mixing effect of concrete.

[0019] Further, a feed pipe and a discharge pipe are fixedly installed on the outer side of the mixing drum. The horizontal position height of the feed pipe is higher than that of the discharge pipe. By setting the position of the feed pipe higher than that of the discharge pipe, on the one hand, when adding concrete into the mixing drum, it can rely on the gravity to fall into the mixing drum more smoothly. On the other hand, when discharging, the concrete in the mixing drum is more likely to gather towards the lower-positioned discharge pipe under the action of gravity, facilitating the discharging operation and reducing the residue of concrete.

[0020] Further, flange plates are fixedly installed at one end of both the feed pipe and the discharge pipe. Through the setting of the flange plates, it is convenient for personnel to quickly connect the feed pipe and the discharge pipe to the material pipe, improving work efficiency.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The multi-axis hybrid mixing equipment for concrete pouring proposed by the present invention drives the mechanism to rotate itself to mix the concrete in the mixing drum, and drives the outer plate member and the inner plate member to rotate around the axis of the driving mechanism through two sets of telescopic members during rotation. Since both the outer plate member and the inner plate member are in a meshing state with the tooth group, when the outer plate member and the inner plate member move to the convex part, the outer plate member and the inner plate member are in the same horizontal state and rotate self - sufficiently, pushing the stones accumulated near the inner wall of the mixing drum into the main mixing flow near the driving mechanism. When the outer plate member and the inner plate member move to the arc part, the outer plate member and the inner plate member gradually change from the same horizontal state to a mutually perpendicular state and rotate self - sufficiently. When the outer plate member and the inner plate member move to the concave part, the outer plate member and the inner plate member are in a mutually perpendicular state and rotate self - sufficiently to mix the pushed - back accumulated stones. Then the outer plate member and the inner plate member move back to the arc part, and the outer plate member and the inner plate member gradually change from the mutually perpendicular state to the same horizontal state, and so on. On the one hand, it can effectively prevent stones from accumulating near the inner wall, resulting in uneven material mixing. On the other hand, it can mix the accumulated stones one step ahead, enabling the stones to better re - integrate into the main mixing flow, improving the mixing effect and mixing efficiency;

[0023] During the rotation process, the rotating shaft will drive the quarter bevel gear to engage with the bevel gear periodically, thereby driving the bevel gear to drive the transmission rod and the third gear to rotate. The third gear in turn drives the fifth tooth rail to drive the driven disk to rotate periodically, thus avoiding the situation where the convex and concave parts cannot cover the inner circumference of the mixing drum due to the fixation of the track, resulting in dead corners.

Detailed Description of the Invention

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0035] Combined Figure 1-4 、 Figure 7-8 A multi-axis hybrid mixing device for concrete pouring, including a mixing drum 1. A multi-axis mixing assembly 2 is arranged inside the mixing drum 1. The multi-axis mixing assembly 2 includes a driving mechanism 21. Stirring mechanisms 22 are symmetrically arranged on both sides of the driving mechanism 21. A driven disk 11 is installed inside the mixing drum 1, and a track 12 is fixedly installed at the lower end of the driven disk 11;

[0036] The driving mechanism 21 includes a servo motor 211 fixedly connected to the outer wall surface of the mixing drum 1. The output end of the servo motor 211 penetrates through the mixing drum 1 and is fixedly installed with a rotating shaft 212;

[0037] The stirring mechanism 22 includes a telescopic member 221 fixedly connected to the driving mechanism 21. One end of the telescopic member 221 is rotatably installed with an outer plate member 222. An inner plate member 223 is rotatably installed inside the outer plate member 222. The track 12 includes a plurality of convex portions 121. Both ends of the convex portion 121 are fixedly connected with arc portions 122. One end of the arc portion 122 away from the convex portion 121 is fixedly connected with a concave portion 123. A tooth group 124 is fixedly arranged on the outer surface of the track 12. Both the outer plate member 222 and the inner plate member 223 are meshed and connected with the tooth group 124;

[0038] A tooth rail five 111 is fixedly installed on the upper surface of the driven disk 11. A quarter bevel gear 213 is fixedly installed on the outer side of the rotating shaft 212. A transmission member 13 is arranged inside the mixing drum 1. The transmission member 13 includes two groups of suspension rods 131 fixedly connected to the inner wall surface of the mixing drum 1. A transmission rod 132 is installed through the inside of the suspension rod 131. The transmission rod 132 is rotatably connected with both groups of suspension rods 131. One end of the transmission rod 132 is fixedly installed with a bevel gear 133. The bevel gear 133 is meshed and connected with the quarter bevel gear 213. The other end of the transmission rod 132 is fixedly installed with a gear three 134. The gear three 134 is meshed and connected with the tooth rail five 111;

[0039] The driving mechanism 21 rotates itself to stir the concrete in the mixing drum 1, and during the rotation, it drives the outer plate member 222 and the inner plate member 223 to rotate around the axis of the driving mechanism 21 through two sets of telescopic members 221. Since both the outer plate member 222 and the inner plate member 223 are in meshing state with the tooth group 124, when the outer plate member 222 and the inner plate member 223 move to the convex portion 121, the outer plate member 222 and the inner plate member 223 are in the same horizontal state and rotate self - sufficiently, pushing the stones accumulated near the inner wall of the mixing drum 1 into the main mixing flow near the driving mechanism 21. When the outer plate member 222 and the inner plate member 223 move to the arc portion 122, the outer plate member 222 and the inner plate member 223 gradually change from the same horizontal state to a mutually perpendicular state and rotate self - sufficiently. When the outer plate member 222 and the inner plate member 223 move to the concave portion 123, the outer plate member 222 and the inner plate member 223 are in a mutually perpendicular state and rotate self - sufficiently to stir and mix the pushed - back accumulated stones. Then the outer plate member 222 and the inner plate member 223 move back to the arc portion 122, and the outer plate member 222 and the inner plate member 223 gradually change from the mutually perpendicular state to the same horizontal state. This process repeats. On the one hand, it can effectively prevent stones from accumulating near the inner wall, resulting in uneven mixing of materials. On the other hand, it can stir and mix the accumulated stones one step ahead, enabling the stones to better re - integrate into the main mixing flow, improving the mixing effect and efficiency. Moreover, during the rotation of the rotating shaft 212, it will simultaneously drive the quarter - bevel gear 213 to engage with the bevel gear 133 periodically, thereby driving the bevel gear 133 to drive the transmission rod 132 and the gear three 134 to rotate. The gear three 134 in turn drives the tooth rail five 111 to drive the driven disk 11 to rotate periodically, thus avoiding the situation that due to the fixation of the track 12, the convex portion 121 and the concave portion 123 cannot cover the inner circumference of the mixing drum 1, resulting in dead corners.

[0040] Combined with Figure 5 , the driving mechanism 21 includes a servo motor 211 fixedly connected to the outer wall surface of the mixing drum 1. The output end of the servo motor 211 penetrates the mixing drum 1 and is fixedly installed with a rotating shaft 212. The lower end of the rotating shaft 212 is fixedly installed with a rotating disk 214. The lower end of the rotating disk 214 is fixedly installed with a stirring rod 215. A plurality of groups of stirring blades 216 are symmetrically and fixedly installed on the outer side of the stirring rod 215. By driving the rotating shaft 212 to rotate through the servo motor 211, the rotating shaft 212 drives the rotating disk 214 and the stirring rod 215 to rotate, so that the plurality of groups of stirring blades 216 rotate around the axis of the stirring rod 215, thereby efficiently stirring and mixing the concrete.

[0041] Combined with Figure 4 , Figure 6-7, the tooth group 124 includes a first toothed rail 1241 fixedly installed on the surface of the track 12, a second toothed rail 1242 fixedly installed on the surface of the convex part 121, a third toothed rail 1243 fixedly installed on the surface of the arc part 122, and a fourth toothed rail 1244 fixedly installed on the surface of the concave part 123;

[0042] The outer plate member 222 includes a first connecting rod 2221 and a first gear 2222 located at the upper end of the first connecting rod 2221 and fixedly connected thereto. Frame plates 2223 are symmetrically and fixedly installed on the outer side of the first connecting rod 2221. A sleeve 2224 is fixedly installed on one side of the two frame plates 2223 close to each other, and a cavity 2225 is reserved between the two frame plates 2223;

[0043] The inner plate member 223 includes a through connecting rod one 2221 and a rotatably connected connecting rod two 2231. A second gear 2232 is fixedly installed at the upper end of the connecting rod two 2231. The lower end of the connecting rod two 2231 is rotatably connected to the sleeve 2224. Fixing plates 2233 are symmetrically and fixedly installed on the outer side of the connecting rod two 2231. The two groups of fixing plates 2233 are fitted with the cavity 2225. During the movement of the outer plate member 222, the first gear 2222 and the first tooth rail 1241 are in a meshed state throughout the process. When the outer plate member 222 and the inner plate member 223 move to the convex portion 121, the second gear 2232 meshes with the second tooth rail 1242. At this time, since the teeth of the first tooth rail 1241 and the second tooth rail 1242 correspond one by one, the first gear 2222 and the second gear 2232 rotate synchronously. Thus, the two groups of fixing plates 2233 fill the cavity 2225, preventing stones from passing through and pushing the stones away from the vicinity of the inner wall of the mixing drum 1. When the outer plate member 222 and the inner plate member 223 move to the arc portion 122, the second gear 2232 ends its meshing connection with the second tooth rail 1242 and then meshes with the third tooth rail 1243. During the subsequent meshing process, the rotation speed of the second gear 2232 is higher than that of the first gear 2222 until the second gear 2232 ends its meshing with the third tooth rail 1243. During this same stroke, since the number of teeth of the third tooth rail 1243 is one-fourth more than that of the first tooth rail 1241, the second gear 2232 rotates 90° more than the first gear 2222, causing the outer plate member 222 and the inner plate member 223 to be in a mutually perpendicular state. Then the outer plate member 222 and the inner plate member 223 move to the concave portion 123, and the second gear 2232 meshes with the fourth tooth rail 1244. At this time, since the teeth of the first tooth rail 1241 and the fourth tooth rail 1244 correspond one by one, the first gear 2222 and the second gear 2232 rotate synchronously, and the cavity 2225 is in an open state, enabling the frame plate 2223 and the fixing plates 2233 to stir and mix the accumulated stones, and the stones can pass through the cavity 2225, thereby increasing the irregular movement of the stones and improving the mixing effect. When the outer plate member 222 and the inner plate member 223 move to the arc portion 122 again, the second gear 2232 rotates 90° more than the first gear 2222 again. When the outer plate member 222 and the inner plate member 223 move to the convex portion 121 again, the first gear 2222 and the second gear 2232 rotate synchronously and the two groups of fixing plates 2233 fill the cavity 2225. This process is repeated. On the one hand, it can effectively prevent stones from accumulating near the inner wall, resulting in uneven material mixing. On the other hand, it can stir and mix the accumulated stones one step ahead, enabling the stones to better re-integrate into the main mixing stream, improving the mixing effect and mixing efficiency.

[0044] Combined Figure 6, the telescopic member 221 includes a cavity rod 2211 fixedly connected to the lower surface of the rotating disk 214. A spring 2212 is fixedly installed on the inner wall surface of the cavity rod 2211. One end of the spring 2212 is fixedly installed with a telescopic rod 2213. One end of the telescopic rod 2213 is rotatably connected to the first connecting rod 2221. During the rotation of the rotating disk 214, the cavity rod 2211 is driven to rotate around the axis of the rotating disk 214, thereby driving the outer plate member 222 and the inner plate member 223 to rotate around the axis of the rotating disk 214. Through the arrangement of the spring 2212 and the telescopic rod 2213, while not affecting the self-rotation of the outer plate member 222, it can adaptively compensate for the difference between the distance from the convex portion 121 to the axis of the rotating disk 214 and the distance from the concave portion 123 to the axis of the rotating disk 214, thus achieving the multi-axis mixing and stirring effect of concrete.

[0045] Combined with Figure 3-4 , the two stirring mechanisms 22 have the same structural composition.

[0046] Combined with Figure 6 , the sleeve 2224 is movably connected to the bottom surface of the inner wall of the mixing drum 1. While not affecting the rotation of the outer plate member 222, it ensures the stable meshing state of the first gear 2222 and the first tooth track 1241, thereby ensuring the efficient mixing and stirring of concrete.

[0047] Combined with Figure 2 , the driven disk 11 is rotatably connected to the inner wall surface of the mixing drum 1. On the one hand, it can reduce the pressure on the output end of the servo motor 211, thereby increasing its service life. On the other hand, it improves the overall stability of the device during operation to ensure the mixing and stirring effect of concrete.

[0048] Combined with Figure 2 , a feed pipe 14 and a discharge pipe 15 are fixedly installed on the outside of the mixing drum 1. The horizontal position height of the feed pipe 14 is higher than the horizontal position height of the discharge pipe 15. Through the setting that the position of the feed pipe 14 is higher than that of the discharge pipe 15, on the one hand, when adding concrete into the mixing drum 1, it can rely on the gravity effect to make it fall into the mixing drum 1 more smoothly by its own gravity. On the other hand, when discharging, the concrete in the mixing drum 1 is more likely to gather towards the lower-positioned discharge pipe 15 under the action of gravity, facilitating the discharging operation and reducing the concrete residue.

[0049] Combined with Figure 2 , flanges 16 are fixedly installed at one ends of the feed pipe 14 and the discharge pipe 15. Through the setting of the flanges 16, it is convenient for personnel to quickly connect the feed pipe 14 and the discharge pipe 15 to the material pipe, improving work efficiency.
