Description

Technical Field

[0001] The invention relates to the technical field of mixing equipment, in particular to multi-axis mixing equipment for concrete pouring. Background Art

[0002] Concrete mixing equipment is a mechanical equipment used to mix cement, sand, gravel and water into concrete mixture. It is widely used on construction sites. Using a mechanized concrete mixer to mix cement can save a lot of manpower and material resources.

[0003] The common existing concrete mixing equipment is usually single-axis forced mixing. Although it is an improvement over manual mixing, there is a mixing dead zone during use. The materials cannot be fully and comprehensively turned over in the mixing drum, and some materials are prone to uneven mixing. As a result, the final concrete produced is unstable in performance indicators such as strength and workability, and cannot meet the growing demand for high-quality concrete in large-scale construction projects.

[0004] For example, a Chinese patent with the existing publication number CN110978277B discloses a concrete mixing device, which starts the motor in the forward direction to drive the driving shaft to rotate, and the driving shaft drives the mixing blades and the mixing arm to rotate, so as to mix the concrete in the concrete mixing box. Since the driving shaft is located at the center of the concrete mixing box and the mass of the gravel in the concrete is much greater than that of cement and sand, the gravel is easily accumulated near the inner wall of the concrete mixing box during the mixing process, resulting in the material being unable to be fully and comprehensively turned over in the mixing drum, resulting in uneven mixing of some materials, making it difficult to ensure the quality of the concrete.

[0005] Therefore, multi-shaft 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 mixing and stirring equipment for concrete pouring, so as to solve the problem in the above-mentioned prior art that gravel is easily accumulated near the inner wall during the mixing process, resulting in uneven mixing of materials and reducing their quality.

[0007] To achieve the above object, the present invention provides the following technical solution: a multi-axis mixing and stirring device for concrete pouring, comprising a mixing drum, a multi-axis mixing assembly is arranged inside the mixing drum, the multi-axis mixing assembly comprises a driving mechanism, mixing 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; The driving mechanism comprises a servo motor fixedly connected to the outer wall surface of the mixing drum, and the output end of the servo motor passes through the mixing drum and is fixedly mounted with a rotating shaft; The stirring mechanism includes a telescopic member fixedly connected to the driving mechanism, an outer plate is rotatably mounted on one end of the telescopic member, an inner plate is rotatably mounted on the inner side of the outer plate, the track includes a plurality of convex parts, both ends of the convex parts are fixedly connected to arc parts, and one end of the arc part away from the convex part is fixedly connected to a concave part, a tooth group is fixedly arranged on the outer surface of the track, and both the outer plate and the inner plate are meshed and connected with the tooth group; A gear track five is fixedly installed on the upper surface of the driven disk, a quarter bevel gear is fixedly installed on the outer side of the rotating shaft, a transmission member is arranged inside the mixing drum, 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 rod, the transmission rod is rotatably connected to the two groups of suspension rods, a bevel gear is fixedly installed on one end of the transmission rod, the bevel gear is meshed with the quarter bevel gear, and a gear three is fixedly installed on the other end of the transmission rod, the gear three is meshed with the gear track five.

[0008] 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 passes 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, the lower end of the rotating disk is fixedly installed with a stirring rod, and multiple groups of stirring blades are symmetrically fixedly installed on the outer side of the stirring rod. The rotating shaft is driven to rotate by the servo motor, and the rotating shaft drives the rotating disk and the stirring rod to rotate, so that the multiple groups of stirring blades rotate about the axis of the stirring rod, thereby efficiently stirring and mixing the concrete.

[0009] Further, the gear set includes a gear track 1 fixedly mounted on the track surface, a gear track 2 fixedly mounted on the convex surface, a gear track 3 fixedly mounted on the arc surface, and a gear track 4 fixedly mounted on the concave surface; The outer plate comprises a connecting rod 1 and a gear 1 located at the upper end of the connecting rod 1 and fixedly connected, a frame plate is symmetrically fixedly installed on the outer side of the connecting rod 1, a sleeve is fixedly installed on the side where the two sets of frame plates are close to each other, and a cavity is reserved between the two sets of frame plates; The inner plate includes a connecting rod 1 that penetrates the connecting rod 1 and a connecting rod 2 that is rotatably connected. The upper end of the connecting rod 2 is fixedly installed with a gear 2. The lower end of the connecting rod 2 is rotatably connected to the sleeve. The outer side of the connecting rod 2 is symmetrically fixedly installed with a fixing plate. The two sets of fixing plates fit the cavity. During the movement of the outer plate, the gear 1 and the rack 1 are in meshing state throughout the whole process. When the outer plate and the inner plate move to the convex position, the gear 2 is meshed with the rack 2. At this time, since the teeth of the rack 1 and the rack 2 correspond one by one, the gear 1 and the gear 2 are synchronized. The outer plate and the inner plate move to the arc position, and the gear 2 ends the meshing connection with the rack 2, and then meshes with the rack 3. In the subsequent meshing process, the self-rotation speed of the gear 2 is higher than the self-rotation speed of the gear 1, until the gear 2 and the rack 3 end the meshing. In the same stroke, the number of teeth on the rack 3 is one-fourth more than that on the rack 1, which makes the gear 2 and the rack 3 mesh. When the outer plate and the inner plate are moved to the convex position again, gear one and gear two rotate synchronously and the two sets of fixed plates fill the cavity, and so on. On the one hand, it can effectively prevent the accumulation of stones near the inner wall, resulting in uneven material mixing. On the other hand, it can stir and mix the accumulated stones one step ahead, so that the stones can be better reintegrated into the mixing mainstream, thereby improving the mixing effect and mixing efficiency.

[0010] Furthermore, 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, one end of the spring is fixedly installed with the telescopic rod, and one end of the telescopic rod is rotatably connected to the connecting rod. During the rotation of the rotating disk, the cavity rod is driven to rotate about the axis of the rotating disk, thereby driving the outer plate and the inner plate to rotate about the axis of the rotating disk. Through the arrangement of the spring and the telescopic rod, 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 can be adaptively compensated without affecting the self-rotation of the outer plate, thereby achieving a multi-axis mixing and stirring effect on concrete.

[0011] Furthermore, the two groups of stirring mechanisms have the same structural composition.

[0012] Furthermore, the sleeve is movably connected to the bottom surface of the inner wall of the mixing drum, which ensures the stable meshing state of the gear 1 and the rack 1 without affecting the rotation of the outer plate, thereby ensuring efficient mixing of the concrete.

[0013] Furthermore, the driven disk is rotatably connected to the inner wall surface of the mixing drum, which can reduce the pressure on the output end of the servo motor and thus increase its service life, and improve the stability of the entire device during operation to ensure the mixing effect of the concrete.

[0014] Furthermore, a feed pipe and a discharge pipe are fixedly installed on the outer side of the mixing drum, and the horizontal position height of the feed pipe is higher than the horizontal position height of the discharge pipe. By setting the feed pipe higher than the discharge pipe, on the one hand, when adding concrete into the mixing drum, it can be made to fall into the mixing drum more smoothly by its own gravity with the help of gravity. On the other hand, when discharging, the concrete in the mixing drum is more easily gathered to the discharge pipe at a lower position under the action of gravity, which facilitates the discharging operation and reduces concrete residue.

[0015] Furthermore, one end of the feed pipe and the discharge pipe is fixedly installed with a flange. The setting of the flange makes it convenient for personnel to quickly connect the feed pipe and the discharge pipe with the material pipe, thereby improving work efficiency.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The multi-axis mixing and stirring equipment for concrete pouring proposed by the present invention has a driving mechanism that rotates itself to stir the concrete in the mixing drum, and in the process of rotation, two sets of telescopic parts drive the outer plate and the inner plate to rotate about the axis of the driving mechanism. Since the outer plate and the inner plate are both in meshing state with the tooth set, when the outer plate and the inner plate move to the convex part, the outer plate and the inner plate are in the same horizontal state and rotate by themselves, pushing the stones accumulated near the inner wall of the mixing drum to the mixing mainstream close to the driving mechanism. When the outer plate and the inner plate move to the arc part, the outer plate and the inner plate gradually move from the same horizontal state to the arc part. The outer plate and the inner plate are in a mutually perpendicular state and rotate. When the outer plate and the inner plate move to the concave part, the outer plate and the inner plate are in a mutually perpendicular state and rotate. The accumulated stones pushed back are stirred and mixed. Then the outer plate and the inner plate move to the arc part again. The outer plate and the inner plate gradually change from a mutually perpendicular state to the same horizontal state. This reciprocating process can effectively prevent stones from accumulating near the inner wall, resulting in uneven material mixing. On the other hand, the accumulated stones can be stirred and mixed one step in advance, so that the stones can be better reintegrated into the mixing mainstream, thereby improving the mixing effect and mixing efficiency. During the rotation process, the rotating shaft will drive the quarter bevel gear to engage with the bevel gear in stages, and then drive the bevel gear to drive the transmission rod and gear three to rotate. Gear three drives the rack track five to drive the driven plate to rotate in stages, thereby 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, thereby preventing the occurrence of dead angles.

[0020] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0021] Combination Figure 1-4 , Figure 7-8 The multi-axis mixing equipment for concrete pouring comprises a mixing drum 1, a multi-axis mixing assembly 2 is arranged inside the mixing drum 1, the multi-axis mixing assembly 2 comprises a driving mechanism 21, mixing 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; The driving mechanism 21 comprises a servo motor 211 fixedly connected to the outer wall surface of the mixing drum 1, and the output end of the servo motor 211 penetrates the mixing drum 1 and is fixedly mounted with a rotating shaft 212; The stirring mechanism 22 includes a telescopic member 221 fixedly connected to the driving mechanism 21, an outer plate 222 is rotatably mounted on one end of the telescopic member 221, an inner plate 223 is rotatably mounted on the inner side of the outer plate 222, the track 12 includes a plurality of convex portions 121, both ends of the convex portions 121 are fixedly connected to arc portions 122, one end of the arc portion 122 away from the convex portion 121 is fixedly connected to a recessed portion 123, a tooth set 124 is fixedly provided on the outer surface of the track 12, and both the outer plate 222 and the inner plate 223 are meshed and connected with the tooth set 124; A rack rail 5 111 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, and the transmission member 13 includes two groups of suspension rods 131 fixedly connected to the inner wall surface of the mixing drum 1, and a transmission rod 132 is installed through the inside of the suspension rod 131, and the transmission rod 132 is rotatably connected to the two groups of suspension rods 131, and a bevel gear 133 is fixedly installed on one end of the transmission rod 132, and the bevel gear 133 is meshed with the quarter bevel gear 213, and a gear 3 134 is fixedly installed on the other end of the transmission rod 132, and the gear 3 134 is meshed with the rack rail 5 111; The driving mechanism 21 rotates to stir the concrete in the mixing drum 1, and during the rotation, the outer plate 222 and the inner plate 223 are driven to rotate about the axis of the driving mechanism 21 through the two sets of telescopic parts 221. Since the outer plate 222 and the inner plate 223 are both in meshing state with the tooth set 124, when the outer plate 222 and the inner plate 223 move to the convex part 121, the outer plate 222 and the inner plate 223 are in the same horizontal state and rotate, The stones accumulated near the inner wall of the mixing drum 1 are pushed into the mixing mainstream near the driving mechanism 21. When the outer plate 222 and the inner plate 223 move to the arc portion 122, the outer plate 222 and the inner plate 223 gradually change from the same horizontal state to a mutually vertical state and rotate. When the outer plate 222 and the inner plate 223 move to the concave portion 123, the outer plate 222 and the inner plate 223 are in a mutually vertical state and rotate, mixing the accumulated stones pushed back. After mixing, the outer plate 222 and the inner plate 223 move back to the arc portion 122, and the outer plate 222 and the inner plate 223 gradually change from a mutually perpendicular state to the same horizontal state, and repeat this process. On the one hand, it can effectively prevent stones from accumulating near the inner wall, resulting in uneven material mixing. On the other hand, the accumulated stones can be stirred and mixed one step in advance, so that the stones can be better reintegrated into the mixing mainstream, thereby improving the mixing effect and mixing efficiency. In addition, the rotating shaft 212 will simultaneously drive the quarter bevel gear 213 to engage with the bevel gear 133 in stages during the rotation process, thereby driving the bevel gear 133 to drive the transmission rod 132 and gear three 134 to rotate, and the gear three 134 drives the rack five 111 to drive the driven disk 11 to rotate in stages, thereby avoiding the situation where the convex portion 121 and the concave portion 123 cannot cover the inner circumference of the mixing drum 1 due to the fixation of the track 12, thereby causing a dead angle.

[0022] Combination 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 passes through the mixing drum 1 and is fixedly installed with a rotating shaft 212. A rotating disk 214 is fixedly installed at the lower end of the rotating shaft 212. A stirring rod 215 is fixedly installed at the lower end of the rotating disk 214. A plurality of stirring blades 216 are symmetrically fixedly installed on the outer side of the stirring rod 215. The rotating shaft 212 is driven to rotate by the servo motor 211, and the rotating shaft 212 drives the rotating disk 214 and the stirring rod 215 to rotate, so that the plurality of stirring blades 216 rotate about the axis of the stirring rod 215, thereby efficiently stirring and mixing the concrete.

[0023] Combination Figure 4 , Figure 6-7The tooth set 124 includes a rack 1241 fixedly mounted on the surface of the track 12, a rack 2 1242 fixedly mounted on the surface of the convex portion 121, a rack 3 1243 fixedly mounted on the surface of the arc portion 122, and a rack 4 1244 fixedly mounted on the surface of the concave portion 123; The outer plate 222 includes a connecting rod 2221 and a gear 2222 located at the upper end of the connecting rod 2221 and fixedly connected. A frame plate 2223 is symmetrically fixedly installed on the outer side of the connecting rod 2221. A sleeve 2224 is fixedly installed on the side where two sets of frame plates 2223 are close to each other. A cavity 2225 is reserved between the two sets of frame plates 2223. The inner plate 223 includes a connecting rod 1 2221 and a connecting rod 2231 that is rotatably connected. The upper end of the connecting rod 2231 is fixedly installed with a gear 2232. The lower end of the connecting rod 2231 is rotatably connected to the sleeve 2224. The outer side of the connecting rod 2231 is symmetrically fixedly installed with a fixing plate 2233. The two sets of fixing plates 2233 fit in the cavity 2225. During the movement of the outer plate 222, the gear 1 2222 and the rack 1 1241 are in meshing state throughout the whole process. When the outer plate 222 and the inner plate 223 move to the convex portion 121, the gear 2232 and the rack 2 1242 are meshed. At this time, due to the contact between the rack 1 1241 and the rack 2 1242, The teeth correspond one to one, and then gear one 2222 and gear two 2232 rotate synchronously, so that the two sets of fixed plates 2233 fill the cavity 2225 to prevent stones from passing through and push the stones away from the inner wall of the mixing drum 1. When the outer plate 222 and the inner plate 223 move to the arc portion 122 position, gear two 2232 ends the meshing connection with rack two 1242, and then meshes with rack three 1243. In the subsequent meshing process, the rotation speed of gear two 2232 is higher than that of gear one 2222, until gear two 2232 ends the meshing with rack three 1243. During this same stroke, because the number of teeth of rack three 1243 is larger than that of rack one 1243, the rotation speed of gear two 2232 is higher than that of gear one 2222. The number of teeth of gear 241 is one quarter more, so that gear 2232 rotates 90° more than gear 1 2222, so that the outer plate 222 and the inner plate 223 are in a mutually perpendicular state as a whole, and then the outer plate 222 and the inner plate 223 move to the recessed portion 123, and gear 2 2232 is meshed with rack 4 1244. At this time, since the teeth of rack 1 1241 and rack 4 1244 correspond one to one, gear 1 2222 and gear 2 2232 rotate synchronously, and the cavity 2225 is in an open state, so that the frame plate 2223 and the fixed plate 2233 stir and mix the accumulated stones, and the stones can pass through the cavity 2225, thereby increasing The irregular mobility of the stones improves the stirring effect. When the outer plate 222 and the inner plate 223 move to the arc 122 position again, the gear 2 2232 rotates 90° more than the gear 1 2222, so that when the outer plate 222 and the inner plate 223 move to the convex portion 121 position again, the gear 1 2222 and the gear 2 2232 rotate synchronously and the two sets of fixed plates 2233 fill the cavity 2225, and so on. On the one hand, it can effectively prevent the stones from accumulating near the inner wall, resulting in uneven material mixing. On the other hand, the accumulated stones can be stirred and mixed one step in advance, so that the stones can be better reintegrated into the stirring mainstream, thereby improving the stirring effect and stirring efficiency.

[0024] Combination Figure 6The telescopic member 221 includes a cavity rod 2211 fixedly connected to the lower surface of the rotating disk 214, and a spring 2212 is fixedly installed on the inner wall surface of the cavity rod 2211. A telescopic rod 2213 is fixedly installed on one end of the spring 2212, and one end of the telescopic rod 2213 is rotatably connected to the connecting rod 2221. During the rotation process, the rotating disk 214 drives the cavity rod 2211 to rotate about the axis of the rotating disk 214, and then drives the outer plate 222 and the inner plate 223 to rotate about the axis of the rotating disk 214. Through the arrangement of the spring 2212 and the telescopic rod 2213, 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 can be adaptively compensated without affecting the rotation of the outer plate 222, thereby achieving a multi-axis mixing and stirring effect on concrete.

[0025] Combination Figure 3-4 The two groups of stirring mechanisms 22 have the same structural composition.

[0026] Combination Figure 6 The sleeve 2224 is movably connected to the bottom surface of the inner wall of the mixing drum 1, and at the same time, the stable meshing state of the gear 2222 and the rack 1241 is ensured without affecting the rotation of the outer plate 222, thereby ensuring efficient mixing of the concrete.

[0027] Combination 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 can enhance the stability of the device as a whole during operation to ensure the mixing effect of the concrete.

[0028] Combination 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. By setting the feed pipe 14 higher than the discharge pipe 15, on the one hand, when adding concrete into the mixing drum 1, it can be made to fall into the mixing drum 1 more smoothly by its own gravity with the help of gravity. On the other hand, when discharging, the concrete in the mixing drum 1 is more easily gathered to the lower position of the discharge pipe 15 under the action of gravity, which is convenient for discharging operation and reduces concrete residue.
