Abstract
Description
Technical Field
[0001] This invention relates to the field of civil engineering technology, and specifically to a concrete mixing device for civil engineering. Background Technology
[0002] With the rapid development of the construction industry, concrete (also known as mortar or cement) is a general term for composite materials made by mixing cementitious materials, aggregates, and water in appropriate proportions and then hardening them over a certain period of time. It is the most widely used artificial civil engineering material in the world, and its quality and performance have received widespread attention. To meet different construction needs, concrete mixing plants, as key equipment for concrete preparation, are constantly being improved and optimized. Areas for improvement when using concrete mixing plants include: When using a concrete mixing device, under normal circumstances, the materials to be mixed are added to the mixing drum through the upper feed pipe. After adding, the upper pipe plug is closed, and then the power is turned on to start the motor. The motor drives the rotating shaft to start mixing. The concrete is further mixed by the mixing rods and connecting rods, so that the concrete in the mixing drum is mixed more evenly. When the mixing device is in use, the mixing rods are used to mix the concrete directly. As a result, some sand and gravel materials in the concrete will be in dead corners and will not be mixed evenly. In addition, during the mixing process, the scraper connected to the outside of the mixing component will directly collide with the inner wall of the mixing drum. The collision between the two for a long time will not only deform the inner wall of the mixing drum due to the collision, but the scraper is also prone to breakage, thereby reducing the service life of the mixing equipment and causing the equipment to be unable to continue mixing concrete. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this invention is achieved through the following technical solution: a concrete mixing device for civil engineering, comprising a transfer inlet, a handle, rollers, a guide cylinder, a guide plate, a mixing device, and a base. The transfer inlet extends through and connects to the interior side of the mixing device. The lower end of the mixing device is fixedly connected to the base, and the upper end of the mixing device is fixedly connected to the guide cylinder. A guide plate is fitted to one side of the guide cylinder, and the guide plate is provided with multiple rollers connected to it. The multiple rollers are mounted on the guide plate and roll. The guide plate is also provided with a handle.
[0004] As a further optimization of the invention, the mixing device includes a cavity, a stirring assembly, a screen, a storage tank, an opening and closing rotating plate, and a discharge chute. The cavity is located inside the storage tank, and a screen is installed parallel to the upper end of the storage tank and a discharge chute connected to it is provided at the lower end. A stirring assembly is vertically connected between the discharge chute and the screen, and the stirring assembly is installed in the storage tank for rotation. An opening and closing rotating plate is arranged parallel to the storage tank and the discharge chute.
[0005] As a further optimization of the invention, the stirring assembly is provided with docking rods, a contact assembly, and a mixing assembly. There are three docking rods, which are equidistantly and annularly inserted into the corresponding positions of the mixing assembly. The contact assembly is fixedly connected to the end of the three docking rods away from the mixing assembly.
[0006] As a further optimization of the invention, the guide plate is moved outward by the handle, and the material used for concrete is placed on the guide plate. The guide plate then guides the material through the guide cylinder into the storage tank inside the mixing device. The mixing component rotates inside the storage tank to mix the concrete material. The connecting rod on the mixing component is fixedly connected to the mixing component, so that the contact component can rotate in coordination with the mixing component inside the storage tank.
[0007] As a further optimization of the invention, the guide plate is equipped with multiple rollers, which can roll simultaneously on the guide plate to guide the concrete material above it into the guide cylinder. The lower end of the guide cylinder is connected to the screen, and the two work together to mix and screen the concrete material before it is introduced into the mixing device for mixing.
[0008] As a further optimization of the invention, the end of the transfer port is inclined and inserted into the discharge trough to connect with the storage tank, so that the material mixed in the storage tank is introduced into the discharge trough through the opening and closing plate and then discharged for use through the guide plate.
[0009] As a further optimization of the invention, the mixing component on the mixing assembly is installed in the middle position inside the storage tank. The mixing component is connected to the contact component through a connecting rod, so that the mixing component and the contact component can cooperate with each other to process the concrete.
[0010] As a further optimization of the invention, the mixing component includes a stirring rod, auxiliary mixing components, a tripod, and flow holes. The stirring rod is fitted with tripods on both sides, and multiple parallel auxiliary mixing components are inserted between the two tripods. These auxiliary mixing components are distributed on the outside of the stirring rod. Each of the three sides of the tripod has multiple flow holes communicating with it. As a further optimization of the invention, the two tripods are symmetrically connected to the left and right sides of the mixing rod, and multiple auxiliary mixing components are provided on both sides. Contact components are installed on the three sides of the tripods, so that when the mixing rod and the auxiliary mixing components work together to mix the concrete, the contact components can scrape the concrete.
[0011] As a further optimization of the invention, the auxiliary mixing component includes a fixing component, a buffer component, a mixing plate, a support component, and a mounting block. The fixing component has multiple buffer components arranged in parallel on one side, and the ends of the multiple buffer components away from the fixing component are fixedly connected to the mounting block. The mounting block has three mixing plates arranged at equal intervals, and a support component is connected to the middle position of the three mixing plates. The ends of the three support components away from the mixing plates are engaged and connected to the mounting block.
[0012] As a further optimization of the invention, the fixing member is fixedly connected to the tripod in parallel. The stirring rod and the fixing member will be driven together by the tripod to stir together. At the same time, the stirring plate connected above will cooperate to mix.
[0013] As a further optimization of the invention, the contact assembly includes a connecting member, a spring support plate, a flexible scraper, and contact heads. There are three connecting members, and the upper and lower ends of the three connecting members are respectively connected to the upper end of the spring support plate and the lower end of the flexible scraper. The spring support plate and the flexible scraper are arranged and connected in an arc-shaped structure. The end of the flexible scraper away from the connecting member is provided with multiple contact heads that are connected thereto.
[0014] As a further optimization of the invention, the elastic support plate is installed on the docking rod. The elastic support plate is made of elastic material and has a certain degree of elasticity and toughness. When connected with the soft scraper, it can play a supporting role, so that the soft scraper can stably clean the storage tank.
[0015] As a further optimization of the invention, the connecting member is provided with a movable spring, a connecting frame, a locking head, a mating strip, and a fitting piece. The movable spring is located in the middle of the connecting frame, and locking heads are installed at both the upper and lower ends of the connecting frame. Fitting pieces are connected to the opposite surfaces of the two locking heads, and the ends of the two fitting pieces away from the locking heads will fit and connect with the two ends of the movable spring.
[0016] As a further optimization of the invention, the connecting frame is installed between the flexible scraper and the contact head via a clamp. When the clamp is subjected to force, it will transmit the pressure to the interior of the movable spring through the fitting. The movable spring will retract inward and extend outward under the force, effectively achieving reciprocating movement between the flexible scraper and the contact head. Beneficial effects
[0017] This invention provides a concrete mixing device for civil engineering, which has the following beneficial effects: 1. This invention uses multiple rollers that can rotate simultaneously to guide concrete material from the guide plate into the guide cylinder. The lower end of the guide cylinder is connected to a screen, and the concrete material is guided onto the screen for sieving. The sieved concrete material is then injected into the storage tank, and the opening and closing rotating plate below it closes, allowing the concrete material to be placed inside the storage tank for mixing. After mixing, the opening and closing rotating plate is opened, and the end of the rotating port is inclined and inserted into the discharge chute to connect with the storage tank. The mixed material in the storage tank is then guided into the discharge chute through the opening and closing rotating plate and discharged through the guide plate for use.
[0018] 2. In this invention, the mixing component is directly inserted into the middle of the cavity. The three connecting rods on the mixing component are fixedly connected to the three corners of the mixing component, allowing the contact component to rotate and move in conjunction with the mixing component inside the storage tank. The two triangular frames on the mixing component are symmetrically connected to the left and right sides of the mixing rod, and multiple auxiliary mixing components are provided on both sides. When the mixing rod and the auxiliary mixing components work together to mix the concrete, the mixing rod and the fixed components are driven to mix together under the action of the triangular frames. At the same time, the mixing plate connected above also plays a cooperating role in mixing. As the fixed components and the mixing rod work together to mix the concrete, the mixing plate cuts into the concrete to improve the uniformity of the mixture.
[0019] 3. In this invention, the contact assembly is mounted on the mixing assembly via a connecting rod. The inner arc surface of the elastic support plate on the contact assembly fits snugly onto the connecting rod. The elastic support plate connects with the flexible scraper, providing support and allowing the flexible scraper to stably clean the storage tank. Three equidistant connecting frames are installed between the flexible scraper and the elastic support plate. During cleaning, the flexible scraper is subjected to the compressive force of the storage tank, which is transmitted to the connecting frames on the connecting member. The two fittings inside the connecting frames, under the action of the connecting rod, simultaneously cooperate with the movable spring to open and close, effectively supporting the flexible scraper and the contact head through reciprocating movement. This allows the flexible scraper and the contact head to effectively clean the concrete adhering to the inner wall of the storage tank.

Detailed Implementation
[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0027] Example 1 Please see Figures 1-5 , This invention provides a concrete mixing device for civil engineering. A concrete mixing device for civil engineering includes a transfer port 1, a handle 2, a roller 3, a guide cylinder 4, a guide plate 5, a mixing device 6, and a base 7. The transfer port 1 extends through and into the side of the mixing device 6 and is connected to the interior of the mixing device 6. The lower end of the mixing device 6 is fixedly connected to the base 7, and the upper end of the mixing device 6 is fixedly connected to the guide cylinder 4. The guide plate 5 is fitted and connected to one side of the guide cylinder 4, and the guide plate 5 is provided with multiple rollers 3 connected to it. The multiple rollers 3 are set on the guide plate 5 and roll. The guide plate 5 is provided with a handle 2.
[0028] The mixing device 6 includes a cavity 61, a stirring assembly 62, a screen 63, a storage tank 64, an opening and closing rotating plate 65, and a discharge chute 66. The cavity 61 is located inside the storage tank 64, and the screen 63 is installed parallel to the upper end of the storage tank 64. The discharge chute 66 is connected to the screen 63 at the lower end. The stirring assembly 62 is vertically connected between the discharge chute 66 and the screen 63. The stirring assembly 62 is mounted on the storage tank 64 and rotates. The opening and closing rotating plate 65 is arranged parallel to the storage tank 64 and the discharge chute 66.
[0029] The stirring assembly 62 is provided with docking rods 621, contact assembly 622, and mixing assembly 623. There are three docking rods 621, and the three docking rods 621 are equidistantly and annularly inserted into the corresponding positions of the mixing assembly 623. The contact assembly 622 is fixedly connected to one end of the three docking rods 621 away from the mixing assembly 623.
[0030] The guide plate 5 is moved outward by the handle 2, and the material to be used for concrete is placed on the guide plate 5. The guide plate 5 then guides the material through the guide cylinder 4 into the storage tank 64 inside the mixing device 6. The mixing component 62 rotates inside the storage tank 64 to mix the concrete material inside. The connecting rod 621 on the mixing component 62 is fixedly connected to the mixing component 623, so that the contact component 622 can rotate inside the storage tank 64 in coordination with the mixing component 623.
[0031] Multiple rollers 3 are installed on the guide plate 5. The multiple rollers 3 can roll on the guide plate 5 at the same time to guide the concrete material above it into the guide cylinder 4. The lower end of the guide cylinder 4 is connected to the screen 63. The two work together to mix and screen the concrete material and introduce it into the mixing device 6 for mixing.
[0032] The end of the transfer port 1 is inclined and inserted into the discharge trough 66 to connect with the storage tank 64, so that the material mixed in the storage tank 64 will be introduced into the discharge trough 66 through the opening and closing plate 65 and then discharged for use through the guide plate 5.
[0033] The mixing component 623 on the mixing assembly 62 is installed in the middle position inside the storage tank 64. The mixing component 623 is connected to the contact component 622 through the connecting rod 621, so that the mixing component 623 and the contact component 622 can cooperate with each other to process the concrete.
[0034] The mixing component 623 includes a stirring rod 6231, auxiliary mixing components 6232, a tripod 6233, and flow holes 6234. The stirring rod 6231 is fitted with tripods 6233 on both sides, and multiple parallel auxiliary mixing components 6232 are inserted between the two tripods 6233. These auxiliary mixing components 6232 are distributed on the outer side of the stirring rod 6231. Each of the three sides of the tripod 6233 has multiple flow holes that communicate with it. The two tripods 6233 are symmetrically connected to the left and right sides of the mixing rod 6231, and multiple auxiliary mixing components 6232 are provided on both sides. Contact components 622 are installed on the three sides of the tripods 6233, so that when the mixing rod 6231 and the auxiliary mixing components 6232 work together to mix the concrete, the contact components 622 can scrape the concrete.
[0035] The auxiliary mixing component 6232 is provided with a fixing component 2321, a buffer component 2322, a mixing plate 2323, a support component 2324, and a mounting block 2325. The fixing component 2321 has multiple parallel buffer components 2322 on one side, and the ends of the multiple buffer components 2322 away from the fixing component 2321 are fixedly connected to the mounting block 2325. The mounting block 2325 is provided with three equidistant mixing plates 2323, and the support component 2324 is connected to the middle position of the three mixing plates 2323. The ends of the three support components 2324 away from the mixing plates 2323 are engaged and connected to the mounting block 2325.
[0036] The fixing member 2321 is fixedly connected in parallel to the tripod 6233. The stirring rod 6231 and the fixing member 2321 will be driven together by the tripod 6233 to stir together. At the same time, the stirring plate 2323 connected above will cooperate to mix.
[0037] The working principle of the above technical solution is explained below: In use, the guide plate 5 is pulled out by the handle 2, and the concrete material is placed on the guide plate 5. Multiple rollers 3 are installed on the guide plate 5, and these rollers 3 can rotate simultaneously to guide the concrete material on the guide plate 5 into the guide cylinder 4. The lower end of the guide cylinder 4 is connected to the screen 63, and the concrete material is then fed onto the screen 63 for sieving. The sieved material then falls into the storage tank 64 inside the mixing device 6. The mixing component 62 rotates inside the storage tank 64 to mix the concrete material. Simultaneously, the opening and closing rotating plate 65 located below the storage tank 64 closes as the concrete material is poured into it. The concrete material is placed inside the storage tank 64 for mixing. After mixing, the end of the transfer port 1 is inclined and inserted into the discharge chute 66 to connect with the storage tank 64. The mixed material in the storage tank 64 is then introduced into the discharge chute 66 through the opening and closing rotating plate 65 and discharged through the guide plate 5. While mixing the concrete material, the mixing component 62 is directly inserted into the middle of the cavity 61. The three connecting rods 621 on the mixing component 62 are fixedly connected to the three corners of the mixing component 623, so that the contact component 622 can rotate and move in coordination with the mixing component 623 inside the storage tank 64. The two triangular brackets 6233 on the mixing component 623 are symmetrical. Connected to the left and right sides of the mixing rod 6231, with multiple auxiliary mixing components 6232 on each side, and contact components 622 installed on three sides between the two tripods 6233, the contact components 622 can scrape the concrete when the mixing rod 6231 and the auxiliary mixing components 6232 work together to mix it. The two ends of the fixing members 2321 on the auxiliary mixing components 6232 are fixedly connected in parallel between the two tripods 6233. The mixing rod 6231 and the fixing members 2321 are driven together by the tripods 6233 to mix together. At the same time, the mixing plate 2323 connected above also plays a cooperating role in mixing. The fixing members 2321 and the mixing plate 2323 interact with each other. When the mixing rod 6231 and the mixing stick are used to mix the concrete, the impact force acts on the fixing member 2321 and the mixing plate 2323. The force on the fixing member 2321 is transmitted to the buffer member 2322. Multiple buffer members 2322 are simultaneously subjected to force to disperse the force. The force on the mixing plate 2323 is transmitted to the corresponding support member 2324. The support member 2324 provides buffer support for the mixing plates 2323 one by one to prevent the mixing plates 2323 from bending and deforming under force. This allows the fixing member 2321 and the mixing rod 6231 to work together to mix the concrete. At the same time, the mixing plate 2323 cuts into the concrete to improve the uniformity of the mixture, so that the sand and gravel materials in the concrete are not not evenly mixed due to dead corners.
[0038] Example 2 Please see Figures 6-7 , This invention provides a concrete mixing device for civil engineering. The contact assembly 622 includes a connecting member 6221, a spring support plate 6222, a flexible scraper 6223, and contact heads 6224. There are three connecting members 6221, and the upper and lower ends of the three connecting members 6221 are respectively connected to the upper end of the spring support plate 6222 and the lower end of the flexible scraper 6223. The spring support plate 6222 and the flexible scraper 6223 are arranged and connected in an arc-shaped structure. The end of the flexible scraper 6223 away from the connecting member 6221 is provided with multiple contact heads 6224 that are connected thereto.
[0039] The elastic support plate 6222 is installed on the connecting rod 621. The elastic support plate 6222 is made of elastic material and has a certain degree of elasticity and toughness. When connected with the soft scraper 6223, it can play a supporting role, so that the soft scraper 6223 can stably clean and scrape the storage tank 64.
[0040] The connecting member 6221 includes a movable spring 2211, a connecting frame 2212, a locking head 2213, a mating strip 2214, and a fitting 2215. The movable spring 2211 is located in the middle of the connecting frame 2212, and locking heads 2213 are installed at both the upper and lower ends of the connecting frame 2212. Fittings 2215 are connected to the opposite surfaces of the two locking heads 2213, and the ends of the two fittings 2215 away from the locking heads 2213 will fit and connect with the two ends of the movable spring 2211.
[0041] The connecting frame 2212 is installed between the flexible scraper 6223 and the contact head 6224 via the clip 2213. When the clip 2213 is subjected to force, it will transmit the pressure to the interior of the movable spring 2211 through the fitting 2215. When the movable spring 2211 is subjected to force, it will retract inward and extend outward, effectively reciprocating between the flexible scraper 6223 and the contact head 6224.
[0042] The working principle of the above technical solution is explained below: In use, the contact component 622 is mounted on the mixing component 623 via the docking rod 621. The inner arc surface of the elastic support plate 6222 on the contact component 622 fits into the docking rod 621. The elastic support plate 6222 is made of elastic material and has a certain degree of elasticity and toughness. When connected with the soft scraper 6223, it can provide support, allowing the soft scraper 6223 to stably clean the storage tank 64. Three equidistant connecting frames 2212 are installed between the soft scraper 6223 and the elastic support plate 6222. The connecting frames 2212 are connected by their upper and lower ends... The clamp head 2213 is installed between the flexible scraper 6223 and the spring support plate 6222. When the stirring rod 6231 rotates, it drives the auxiliary mixing component 6232 to rotate simultaneously via the tripod 6233. The flexible scraper 6223 connected above it is also driven to rotate, and simultaneously contacts the inner wall of the storage tank 64. The flexible scraper 6223 is equipped with multiple contact heads 6224, which are made of rubber material. These contact heads 6224 contact the flexible scraper 6223 and the inner wall of the storage tank 64 to perform a scraping action. During the scraping process, the flexible scraper 6223... Under the pressure of the storage tank 64, the pressure is transmitted to the connecting frame 2212 on the connecting member 6221. The clamp 2213 on the connecting frame 2212, under pressure, transmits the pressure through the fitting 2215 to the interior of the movable spring 2211. The movable spring 2211, under pressure, retracts inward and expands outward. Simultaneously, the fittings 2215 connected to the upper and lower ends of the movable spring 2211 connect with the connecting strip 2214, causing the two fittings 2215 to simultaneously cooperate with the movable spring 2211 in opening and closing movements under the action of the connecting strip 2214, effectively controlling the soft scraper 622. The reciprocating motion between the flexible scraper 6223 and the contact head 6224 provides support, allowing the flexible scraper 6223 and the contact head 6224 to effectively scrape away the concrete adhering to the inner wall of the storage tank 64. This not only protects the inner wall of the storage tank 64 but also removes the concrete adhering to it, thus protecting both simultaneously. This prevents the storage tank 64 from deforming due to impact, and the flexible scraper 6223 is less prone to breakage, effectively improving the service life of the mixing equipment and ensuring that the equipment can stably continue to mix and produce concrete.
