Description

Technical Field

[0001] The present application relates to the technical field of concrete processing, and in particular to a semi-automatic concrete feeding and mixing system. Background Art

[0002] In the process of the booming construction industry, concrete, as one of the most widely used building materials, the development of its mixing technology is crucial. A concrete mixing device is a device used to mix various raw materials of concrete (such as cement, sand, gravel, water and admixtures, etc.) in a certain proportion to produce concrete that meets the requirements of construction.

[0003] In the prior art, a Chinese patent publication numbered CN115214018B discloses a concrete mixer, comprising a mixing tank and a mounting frame, wherein the mounting frame is arranged inside the mixing tank; and a vibration mechanism is connected to the mounting frame and is used to vibrate the concrete. The present invention can defoam the raw materials while preparing the concrete, thereby avoiding the subsequent reprocessing of the prepared concrete, thereby greatly shortening the time for preparing the concrete and accelerating the preparation efficiency of the concrete. Secondly, the concrete can be defoamed while being prepared. In order to achieve a better mixing effect of the raw materials, the raw materials generally need to be stirred and turned for a long time. Stirring and turning the raw materials for a long time can greatly extend the defoaming time, thereby achieving a better defoaming effect of the raw materials. In this way, not only can concrete with a better mixing condition be prepared, but also concrete with a better defoaming effect can be prepared, and at the same time, a large amount of time for defoaming can be saved, thereby further accelerating the preparation efficiency of the concrete and achieving a better effect of the prepared concrete.

[0004] Existing concrete mixing devices rely on manual transportation and feeding of raw materials, which not only requires a large amount of manpower, but also makes it difficult to accurately control the amount and timing of raw materials added by manual operation, which can easily lead to unstable concrete quality. For example, when manually feeding materials directly into the mixing tank, the raw materials are usually poured into the mixing tank in sequence and then stirred after pouring. Since it is impossible to accurately distribute different raw materials evenly in the mixing tank, the raw materials often accumulate in layers in the middle of the mixing tank, which seriously affects the uniformity of mixing. It takes a long time to mix the raw materials evenly, resulting in low work efficiency. Summary of the invention

[0019] 2.

The advantages are: first, the amount of each raw material can be controlled more accurately. Compared with feeding directly into the mixing tank, this method of first batching the materials in the receiving hopper can reduce the batching error caused by factors such as different feeding speeds; second, the unified feeding of raw materials can make the various raw materials have a more uniform initial distribution in the mixing tank, which is beneficial for the mixing mechanism to fully mix the various raw materials at the initial stage of mixing and shorten the time required to reach a uniform mixing state; third, the production efficiency is improved.

After dispersion, the raw materials are immediately stirred by a plurality of stirring components, thereby achieving a good mixing effect.

[0022] 5. The present invention provides a driving assembly so that the stirring assembly can rotate around the central axis of the stirring rod itself while the stirring assembly rotates around the central axis of the stirring tank, thereby improving the stirring efficiency of the stirring assembly and making the concrete raw materials mixed more evenly.

[0040] like Figure 1-Figure 12 As shown, a semi-automatic concrete feeding and mixing system according to an embodiment of the present application includes a support frame 100, a mixing tank 400 is fixedly mounted on the support frame 100, a feeding mechanism 200 is arranged at the top of the mixing tank 400, the feeding mechanism 200 includes a feeding assembly 210, a transmission assembly 220 and a feeding hopper 230, a feeding assembly 210 is installed with a receiving hopper 500, the feeding hopper 230 is fixedly mounted on the top of the mixing tank 400 and the middle part is connected to the mixing tank 400, the transmission assembly 220 Connected to one end of the feed hopper 230, the mixing tank 400 is provided with a stirring mechanism 300 for stirring concrete raw materials, and the stirring mechanism 300 includes a driving component 310, a stirring component 320 and a material distribution rack 330. The driving component 310 is arranged at the upper end of the mixing tank 400, the stirring component 320 is rotatably arranged inside the mixing tank 400, the material distribution rack 330 is arranged below the feeding port of the mixing tank 400, and the bottom of the material distribution rack 330 is connected to the driving component 310 through a support rod 340.

[0041] In the specific setting, the receiving hopper 500 is used to receive concrete raw materials. The concrete raw materials are poured into the receiving hopper 500, and the receiving hopper 500 is tilted by the feeding assembly 210. One end of the receiving hopper 500 is located above the feeding hopper 230. During the tilting process of the receiving hopper 500, the concrete raw materials gradually fall into the feeding hopper 230. During this process, the transmission assembly 220 opens the cover plate 231 in the feeding hopper 230 to facilitate the feeding of concrete raw materials.

[0042] The stirring mechanism 300 mixes and stirs the concrete raw materials. The function of the material distribution rack 330 is to evenly disperse the raw materials during the falling process of the raw materials to achieve preliminary mixing of the raw materials and prevent the raw materials from accumulating in the middle of the mixing tank 400. The driving component 310 drives the stirring component 320 to rotate, fully stir the dispersed raw materials, make the raw materials mixed evenly, and produce concrete that meets the requirements.

[0043] During the whole process, through the coordinated operation of the feeding mechanism 200 and the mixing mechanism 300, a semi-automatic feeding and mixing process is realized, the efficiency and quality of concrete production are improved, the manpower input is reduced, and the uniformity and stability of mixing are ensured.

[0044] The feeding assembly 210 includes a movable frame 211 and a fixed frame 212. The movable frame 211 and the fixed frame 212 are fixedly installed on the receiving hopper 500 and the mixing tank 400 respectively. A connecting seat 213 is fixedly installed on the top of the fixed frame 212. The movable frame 211 is rotatably installed on the connecting seat 213. A hydraulic cylinder 214 is hinged on the fixed frame 212. The output end of the hydraulic cylinder 214 is hinged to one end of the movable frame 211 close to the feed hopper 230.

[0045] In the specific setting, the receiving hopper 500 and the feeding assembly 210 are both provided with two, and the two movable frames 211 are respectively fixedly installed on the receiving hopper 500. The receiving hopper 500 is in the shape of a cut tank, and the end of the discharge is smoothly retracted inward, which can accommodate more concrete raw materials in a horizontal state, and can also be more concentrated when discharging to avoid spilling out of the feed hopper 230. The connecting seat 213 is connected to the middle part of the movable frame 211, so that the movable frame 211 and the receiving hopper 500 are connected by the connection on the connecting seat 213. The bottom of the hydraulic cylinder 214 is hinged to the lower end of the movable frame 211, and the output end is hinged to one end of the movable frame 211. When receiving materials, the hydraulic cylinder 214 is started to extend its rod, driving the movable frame 211 to tilt until the movable frame 211 is horizontal, and then the raw materials are poured into the receiving hopper 500, and then the rod of the hydraulic cylinder 214 is retracted to make the movable frame 211 tilt in the opposite direction, and the discharge end of the receiving hopper 500 is close to the feed hopper 230, and the raw materials enter the feed hopper 230 from the receiving hopper 500.

[0046] Through the above arrangement, after both receiving hoppers 500 have received enough raw materials, they can be passed into the feed hopper 230 together. The advantages of this design are: first, when adding raw materials to the two receiving hoppers 500 respectively, the amount of each raw material can be controlled more accurately. For the production of high-performance concrete that needs to be strictly carried out according to the proportion, metering equipment can be used in the receiving hopper 500 stage to accurately measure the amount of key raw materials such as cement and admixtures, thereby ensuring the stability of the quality of concrete. Compared with directly feeding into the mixing tank 400, this method of first mixing in the receiving hopper 500 can reduce the mixing error caused by factors such as different feeding speeds. Second, the unified feeding of raw materials can make various raw materials have a more uniform initial distribution in the mixing tank 400. If the raw materials are added one after another Putting the raw materials into the mixing tank 400 separately may cause the raw materials put in first to accumulate at the bottom of the mixing tank 400, and the raw materials put in later to be distributed on the surface, requiring a longer mixing time to achieve uniform mixing. However, by uniformly putting the raw materials in through the receiving hopper 500, the raw materials can enter the mixing tank 400 at the same time, which is beneficial for the mixing mechanism 300 to fully mix various raw materials at the initial stage of mixing, shortening the time required to achieve a uniform mixing state. Thirdly, in the process of collecting raw materials in the receiving hopper 500, the mixing tank 400 can simultaneously unload or clean the previous batch of concrete. When the raw materials in the receiving hopper 500 are ready, the raw materials can be quickly put into the mixing tank 400 to start mixing a new batch of concrete, thereby reducing the idle time of the mixing equipment and improving the overall production efficiency.

[0047] The transmission assembly 220 includes a tooth plate 221 and a mounting block 224, the mounting block 224 is fixedly connected to one side of the feed hopper 230, the tooth plate 221 is slidably sleeved on the mounting block 224, and limiting grooves 225 are provided on both sides of the tooth plate 221, and limiting blocks 228 are fixedly connected on both sides of the mounting block 224. The limiting blocks 228 are slidably connected to the inner walls of the limiting grooves 225, and a telescopic rod 227 is fixedly installed inside the mounting block 224. The top of the telescopic rod 227 is fixedly connected to the top inner wall of the tooth plate 221, and a spring 226 is sleeved on the body of the telescopic rod 227. The two ends of the spring 226 are respectively fixedly connected to the top inner wall of the tooth plate 221 and the upper surface of the mounting block 224, and one side of the upper end of the tooth plate 221 is fixedly connected to a mounting seat 223, and a roller 222 is rotatably installed on the mounting seat 223, and the roller 222 abuts against one end of the receiving hopper 500.

[0048] A first gear 229 and a first transmission wheel 2210 are rotatably mounted on one side of the mounting block 224, the first gear 229 is coaxially connected to the first transmission wheel 2210, the first gear 229 is meshed with the tooth plate 221, the first gear 229 is meshed with the second gear 2213 on the side away from the tooth plate 221, a transmission belt 2212 is sleeved on the first transmission wheel 2210, one end of the transmission belt 2212 away from the first transmission wheel 2210 is sleeved on the second transmission wheel 2211, cover plates 231 are rotatably connected on both sides of the feed hopper 230, first rotating shafts 232 are fixedly mounted on the cover plates 231 on both sides, and one end of the cover plates 231 on both sides are fixedly connected to the second transmission wheel 2211 and the second gear 2213 respectively.

[0049] In the present application, the function of the transmission assembly 220 is: when the receiving hopper 500 is tilted to discharge materials, the two cover plates 231 are synchronously driven to rotate, so that the cover plates 231 that were originally in a closed state are opened to facilitate the discharge of raw materials. After the discharge is completed, the cover plates 231 are driven to rotate in the opposite direction to close the cover plates 231, thereby preventing debris from entering the mixing tank 400 and also preventing dust from flying out to cause environmental pollution.

[0050] During the specific setting, the tooth plate 221 can slide up and down along the mounting block 224, and the tooth plate 221 is meshed with the first gear 229, which can drive the first gear 229 and the second gear 2213 to rotate. The second gear 2213 drives the first rotating shaft 232 and the cover plate 231 on one side to rotate. The first gear 229 drives the first rotating shaft 232 and the cover plate 231 on the other side to rotate in the opposite direction through the transmission cooperation of the first transmission wheel 2210, the second transmission wheel 2211 and the transmission belt 2212, thereby realizing the closing or opening of the cover plates 231 on both sides, which plays a role of isolation.

[0051] Specifically, the receiving hopper 500 presses down the roller 222, and the roller 222 drives the tooth plate 221 to move downward, the spring 226 and the telescopic rod 227 contract, and the limit block 228 moves upward relative to the tooth plate 221, and the first gear 229 and the second gear 2213 rotate synchronously, and the second gear 2213 rotates in the opposite direction to the first gear 229. The second gear 2213 drives the cover plate 231 on this side to flip downward, and the first gear 229 drives the cover plate 231 on the other side to flip downward, and the raw material enters the mixing tank 400 from the feeding hopper 230. After the material is unloaded, the receiving hopper 500 rotates in the opposite direction, and the pressure applied to the roller 222 gradually decreases. The tooth plate 221 gradually moves upward under the elastic force of the spring 226, driving the cover plates 231 on both sides to flip upward, thereby achieving the closure of the feeding port.

[0052] The driving assembly 310 includes a motor 311, a first gear ring 313 and a second gear ring 316. The motor 311 is fixedly installed on the upper end of the stirring tank 400. The first gear ring 313 is rotatably installed on the top inner wall of the stirring tank 400.

The output end of the motor 311 is fixedly connected to the third gear 312, and the third gear 312 is meshingly connected to the first gear ring 313. The bottom of the first gear ring 313 is rotatably connected to a plurality of second rotating shafts 314. The upper end of each second rotating shaft 314 is fixedly connected to a fourth gear 315, and the fourth gear 315 is meshingly connected to the second gear ring 316.

[0053] In the present application, the function of the driving component 310 is to drive a plurality of stirring components 320 to rotate, so as to achieve stirring and mixing of concrete raw materials.

[0054] Specifically, the first gear ring 313 is rotatably mounted on the top inner wall of the mixing tank 400, the second gear ring 316 is sleeved on the outside of the first gear ring 313, the upper end of the second gear ring 316 is fixedly connected to the top inner wall of the mixing tank 400, and the lower end is meshed with the fourth gear 315, the third gear 312 is located above the fourth gear 315, and the meshing portion of the third gear 312 and the first gear ring 313 is located above the meshing portion of the fourth gear 315 and the second gear ring 316 to avoid obstruction of transmission.

[0055] When working, the third gear 312 is driven to rotate by starting the motor 311, and the third gear 312 drives the first ring gear 313 and the plurality of second rotating shafts 314 to rotate. During the rotation process, the second rotating shaft 314 rotates around its own central axis through the meshing connection between the fourth gear 315 and the second ring gear 316, thereby improving the mixing efficiency of the mixing assembly 320 and making the concrete raw materials mixed more evenly.

[0056] A support rod 340 is rotatably connected to the lower end of the second rotating shaft 314 . One end of the support rod 340 away from the second rotating shaft 314 is fixedly connected to the bottom of the material distribution frame 330 .

[0057] Specifically, the support rod 340 is used to support the distribution rack 330. The distribution rack 330 is conical, and the internal material guide groove 331 is a smooth arc, which can facilitate the sliding of the raw materials. The distribution rack 330 is set at the upper feed port of the mixing tank 400, and can disperse the fallen raw materials. The distribution rack 330 rotates with the first gear ring 313, and can evenly disperse the raw materials. After dispersion, it is immediately stirred by a number of stirring components 320, thereby achieving a good mixing effect.

[0058] The stirring assembly 320 includes a stirring rod 321, the top of which is fixedly connected to the second rotating shaft 314, and the upper and lower ends of the stirring rod 321 are respectively fixedly connected to an upper mounting plate 322 and a lower mounting plate 324, and spiral blades 323 are fixedly installed on the upper mounting plate 322 and the lower mounting plate 324, and an arc-shaped blade 325 is fixedly installed on the bottom of the lower mounting plate 324.

The spiral blade 323 is set to different spiral directions, which can generate an upward or downward thrust on the concrete raw material during the rotation process, so that the raw materials located at different heights of the mixing tank 400 are fully turned over. The arc blade 325 mainly stirs and mixes the raw materials at the bottom, and cooperates with the spiral blade 323 to ensure the uniformity of the mixing of the raw materials in various places in the mixing tank 400.

[0060] In summary, the working principle of a semi-automatic concrete feeding and mixing system according to an embodiment of the present invention is as follows:

[0061] During operation, the hydraulic cylinder 214 is started to extend its rod, driving the movable frame 211 to tilt until the movable frame 211 is horizontal, and then the raw materials are poured into the receiving hopper 500, and then the rod of the hydraulic cylinder 214 is retracted to make the movable frame 211 tilt in the opposite direction, and the discharge end of the receiving hopper 500 is close to the feeding hopper 230, and the raw materials enter the feeding hopper 230 from the receiving hopper 500. In this process, the receiving hopper 500 presses the roller 222, and the roller 222 drives the tooth plate 221 to move downward, the spring 226 and the telescopic rod 227 contract, and the limit block 228 moves upward relative to the tooth plate 221. The first gear 229 and the second gear 2213 rotate synchronously, and the second gear 2213 rotates in the opposite direction to the first gear 229. The second gear 2213 drives the cover plate 231 on this side to flip downward, and the first gear 229 drives the cover plate 231 on the other side to flip downward. The raw materials enter the mixing tank 400 from the feed hopper 230. After the feeding is completed, the receiving hopper 500 rotates in the opposite direction, and the pressure applied to the roller 222 gradually decreases. The tooth plate 221 gradually moves upward under the elastic force of the spring 226, driving the cover plates 231 on both sides to flip upward, thereby realizing the closure of the feed port.

[0062] The starting motor 311 drives the third gear 312 to rotate, and the third gear 312 drives the first gear ring 313 and the plurality of second rotating shafts 314 to rotate. During the rotation process, the second rotating shaft 314 rotates around its own central axis through the meshing connection between the fourth gear 315 and the second gear ring 316, and the stirring assembly 320 rotates synchronously with the second rotating shaft 314. During the rotation process, the spiral blades 323 and the arc blades 325 stir and mix the concrete raw materials at the same time to ensure the uniformity of the mixing of the concrete raw materials.

[0063] The electronic components and models used in the present invention can be selected according to actual needs.
