Description
Technical Field
[0001] The utility model relates to the field of mixing devices, in particular to a concrete mixing device which is easy to clean and is used in culvert production. Background Art
[0002] Culvert refers to a pipe buried below the ground surface, commonly known as cement pipe, which is used as a water diversion pipe under the entire cofferdam dam and is generally used as a water delivery pipe. In most cities in my country, water supply and drainage pipes are made of cement, lime and water, mixed and stirred evenly, and then poured into cement pipes as culverts to ensure the reliability of welded pipes.
[0003] The existing concrete mixing devices used in culvert production are mostly composed of a mixing box, a motor, a stirring rod and other components. After the workers put the concrete raw materials and water into the mixing box according to a certain ratio, they start the motor to drive the stirring rod to stir the concrete raw materials inside. After the mixing is completed, the concrete raw materials can be transported through a specific transportation device for casting and forming of the culvert.
[0004] However, after most existing concrete mixing devices complete the mixing of concrete raw materials, in order to ensure that the concrete can be used normally, the mixed concrete is mostly relatively viscous, which makes it easy for concrete residue to be generated inside the mixing box. After a long period of no use, the concrete inside it solidifies, which will cause it to reduce the space inside the mixing box, reduce the mixing effect of the mixing device on the concrete, and reduce the service life of the mixing device, causing certain economic losses. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a concrete mixing device for culvert production that is easy to clean, so as to solve the technical problems mentioned in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete mixing device for culvert production that is easy to clean, comprising a support frame, a mixing tank is fixedly installed at one end of the support frame, and a motor is fixedly installed at one end of the mixing tank, a mixing shaft is fixedly installed at the output end of the motor, and a plurality of mixing blocks are fixedly installed on the outside of the mixing shaft, a cover plate is movably installed at one end of the mixing tank, and a rack is fixedly installed at one end of the cover plate, a rotating rod is movably installed inside the mixing tank, and a gear meshing with the rack is fixedly installed at one end of the rotating rod, a threaded rod is movably installed inside the mixing tank, and a feeding port for discharging is provided at one end of the mixing tank, a belt is sleeved on the outside of the rotating rod, and the threaded rod and the rotating rod are connected by the belt, a scraper for cleaning the inner wall of the mixing tank is movably installed at one end of the threaded rod, and a threaded groove matching the threaded rod is provided inside the scraper.
[0007] By adopting the above technical scheme, by arranging components such as racks, gears, rotating rods, belts, threaded rods and scrapers, when workers use the equipment and need to discharge and add new concrete raw materials after completing the mixing of concrete, they only need to pull the handle to control the position of the baffle to complete the discharging. When the discharging is almost finished and the cover needs to be opened to add materials, the gear is driven by the rack, so that the scraper is driven by the threaded rod to automatically clean the inside of the mixing tank from top to bottom, and push and scrape the residual concrete raw materials inside to fall on the bottom slope of the mixing tank. Compared with the traditional mixing device, the equipment can automatically clean the inner wall of the mixing tank through a series of transmissions during the process of opening the cover and adding materials, effectively preventing concrete residue inside, ensuring the mixing effect of the mixing device on the concrete, eliminating the need for subsequent workers to manually clean the inner end face of the mixing tank, effectively reducing the work intensity of the workers, and increasing the service life of the equipment.
[0008] The utility model is further configured that a cleaning plate is fixedly installed at one end of the stirring shaft, and the cleaning plate is in contact with the bottom end surface of the stirring tank, a limiting rod for limiting the scraper is fixedly installed inside the stirring tank, and the limiting plate is fixedly installed at one end of the limiting rod.
[0009] By adopting the above technical solution, the fixedly installed cleaning plate can rotate along with the stirring shaft. The cleaning plate can effectively prevent some raw materials inside the mixing tank from precipitating, thereby improving the mixing effect of the concrete. The setting of the limit rod and the limit plate can effectively prevent the scraper from rotating along with the threaded rod, thereby ensuring its cleaning effect. At the same time, the limit plate can limit its moving distance, prevent the scraper from detaching from the threaded rod, and improve the overall reliability of the equipment.
[0010] The utility model is further configured that a fixing block is fixedly installed at one end of the mixing tank, and a limiting block is fixedly installed inside the fixing block, and a limiting groove matching the limiting block is opened inside the cover plate.
[0011] By adopting the above technical solution, the mixing tank provides fixation and restriction for the fixed block, and the limit block cooperates with the limit groove to effectively limit the movement direction and distance of the cover plate, ensuring that its position will not shift during the movement, thereby affecting the rack and being unable to drive the gear.
[0012] The utility model is further configured that a fixing plate is fixedly installed at one end of the support frame, a connecting rod is movably installed inside the fixing plate, and a handle is fixedly installed at one end of the connecting rod.
[0013] By adopting the above technical solution, the support frame provides fixation and restriction for the fixed plate, and the movably installed connecting rod allows it to move inside the fixed plate. At the same time, the movement of the connecting rod is restricted by the fixed plate. The setting of the handle can make it more convenient for workers to control the position of the baffle, control its unloading speed, and improve their overall work efficiency.
[0014] The utility model is further configured that a baffle is fixedly mounted on one end of the connecting rod, and the diameter of the baffle is larger than the diameter of the feed opening.
[0015] By adopting the above technical solution, the fixedly installed baffle plate allows the worker to drive the baffle plate to move when pulling the handle, thereby achieving the purpose of controlling the opening and closing of the discharge port. At the same time, the diameter of the baffle plate is larger than the diameter of the discharge port, which can effectively ensure that the concrete raw materials inside the mixing tank cannot fall out when it is in the reset state, ensuring that the mixing shaft and the mixing block can normally mix the concrete raw materials inside it.
[0016] The utility model is further configured that a spring is sleeved on the outside of the connecting rod, and the baffle plate is connected to the fixed plate through the spring, and the inner diameter length of the scraper plate is greater than the length of the multiple groups of stirring blocks.
[0017] By adopting the above technical solution, the spring will continuously apply elastic force to the baffle, so that after the worker releases the pulling force on the handle, the spring will reset the baffle for the first time, preventing the worker from forgetting to close the baffle during the process of adding raw materials and affecting the work progress. The inner diameter of the scraper is larger than the stirring block, so that the scraper will not contact the stirring block during the downward displacement process, ensuring that it can normally scrape off the residual concrete raw materials in the mixing tank, thereby increasing the service life of the equipment and reducing the work intensity of the workers.
[0018] In summary, the utility model mainly has the following beneficial effects:
[0019] 1. The utility model is provided with components such as racks, gears, rotating rods, belts, threaded rods and scrapers, so that when workers use the equipment, when they need to discharge the concrete and add new concrete raw materials after completing the mixing of the concrete, they only need to pull the handle to control the position of the baffle to complete the discharging. When the discharging is almost finished and the cover needs to be opened to add materials, the gear is driven by the rack, so that the scraper is driven by the threaded rod to automatically clean the inside of the mixing tank from top to bottom, and push and scrape the residual concrete raw materials inside to make them fall on the bottom inclined surface of the mixing tank. Compared with the traditional mixing device, the equipment can automatically clean the inner wall of the mixing tank through a series of transmissions during the process of opening the cover and adding materials, effectively preventing the concrete residue inside, ensuring the mixing effect of the mixing device on the concrete, eliminating the need for subsequent workers to manually clean the inner end face of the mixing tank, effectively reducing the work intensity of the workers, and prolonging the service life of the equipment.
[0020] 2. The utility model is provided with a mixing tank, a cleaning plate, a baffle, a spring and a discharge port. The setting of the cleaning plate can effectively prevent part of the raw materials from settling at the bottom when the concrete raw materials inside the mixing tank are mixed, thereby affecting the mixing effect. The cleaning plate rotates together with the mixing shaft, so that it can continuously mix the concrete raw materials on the inclined surface of the bottom of the mixing tank, thereby ensuring the mixing effect of the mixing equipment. At the same time, the setting of the cleaning plate enables the worker to operate the handle to control the baffle to discharge the concrete raw materials mixed inside the mixing tank. The cleaning plate will cooperate with the scraper to push the concrete raw materials remaining on the inclined surface of the bottom of the mixing tank to discharge it from the inside of the mixing tank, thereby accelerating the overall discharge speed and improving the overall mixing efficiency.

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0027] The following describes an embodiment of the utility model based on its overall structure.
[0028] A concrete mixing device for culvert production that is easy to clean, such as Figure 1-4 As shown, it includes a support frame 1, a stirring tank 2 is fixedly installed at one end of the support frame 1, a motor 10 is fixedly installed at one end of the stirring tank 2, and a stirring shaft 7 is fixedly installed at the output end of the motor 10, and a plurality of stirring blocks 8 are fixedly installed on the outside of the stirring shaft 7, a cover plate 9 is movably installed at one end of the stirring tank 2, and a rack 6 is fixedly installed at one end of the cover plate 9, a rotating rod 12 is movably installed inside the stirring tank 2, and a gear 11 meshing with the rack 6 is fixedly installed at one end of the rotating rod 12, a threaded rod 14 is movably installed inside the stirring tank 2, and a discharge port 24 for discharging is provided at one end of the stirring tank 2, a belt 13 is sleeved on the outside of the rotating rod 12, and the threaded rod 14 is connected to the rotating rod 12 by the belt 13, a scraper 15 for cleaning the inner wall of the stirring tank 2 is movably installed at one end of the threaded rod 14, and the scraper 15 is provided inside with a gear meshing with the rack 6 The threaded rod 14 matches the threaded groove. When the mixing is completed and the concrete raw materials inside the mixing tank 2 need to be discharged, the worker only needs to pull the handle 21 to drive the baffle 19 to move and discharge the concrete raw materials inside the mixing tank 2 through the discharge port 24. After the discharge is completed, the worker moves the cover plate 9, which makes it convenient for the worker to add materials. During the movement of the cover plate 9, the gear 11 is driven by the rack 6 to rotate, so that the rotating rod 12 rotates together, and then the belt 13 is used to drive the scraper 15 to move from top to bottom along the threaded rod 14, thereby pushing the concrete raw materials remaining on the inner wall of the mixing tank 2 and cleaning the inside thereof. The remaining concrete raw materials will fall to the bottom inclined surface of the mixing tank 2 under the push of the scraper 15 and the influence of gravity, and the concrete inside it will be discharged from the inside of the mixing tank 2 through the cooperation of the scraper 15 and the cleaning plate 18.
[0029] See also Figure 2 - Figure 4A cleaning plate 18 is fixedly installed at one end of the stirring shaft 7, and the cleaning plate 18 is in contact with the bottom end surface of the stirring tank 2. A limiting rod 16 for limiting the scraper 15 is fixedly installed inside the stirring tank 2, and a limiting plate 17 is fixedly installed at one end of the limiting rod 16. The fixedly installed cleaning plate 18 allows it to rotate together with the stirring shaft 7. The cleaning plate 18 can effectively prevent the raw materials inside the stirring tank 2 from precipitating, thereby improving the mixing effect of the concrete. The setting of the limiting rod 16 and the limiting plate 17 can effectively prevent the scraper 15 from rotating together with the threaded rod 14, thereby ensuring its cleaning effect. At the same time, the limiting plate 17 can limit its moving distance, thereby preventing the scraper 15 from detaching from the threaded rod 14, thereby improving the overall reliability of the equipment.
[0030] See also Figure 4 A fixing block 3 is fixedly installed at one end of the mixing tank 2, and a limiting block 4 is fixedly installed inside the fixing block 3. A limiting groove 5 matching the limiting block 4 is opened inside the cover plate 9. The mixing tank 2 provides fixation and limitation for the fixing block 3. At the same time, the limiting block 4 cooperates with the limiting groove 5 to effectively limit the moving direction and distance of the cover plate 9, ensuring that its position will not be offset during the movement, thereby affecting the rack 6 from driving the gear 11.
[0031] See also Figure 1 - Figure 4 A fixing plate 20 is fixedly installed at one end of the support frame 1, and a connecting rod 22 is movably installed inside the fixing plate 20, and a handle 21 is fixedly installed at one end of the connecting rod 22. The support frame 1 provides fixation and restriction for the fixing plate 20. The movably installed connecting rod 22 allows it to move inside the fixing plate 20, and at the same time, the movement of the connecting rod 22 is restricted by the fixing plate 20. The setting of the handle 21 can make it more convenient for workers to control the position of the baffle 19, control its unloading speed, and improve their overall work efficiency.
[0032] See also Figure 4 A baffle 19 is fixedly installed at one end of the connecting rod 22, and the diameter of the baffle 19 is larger than the diameter of the discharge port 24. The fixedly installed baffle 19 allows the worker to drive the baffle 19 to move when pulling the handle 21, thereby achieving the purpose of controlling the opening and closing of the discharge port 24. At the same time, the diameter of the baffle 19 is larger than the diameter of the discharge port 24, which can effectively ensure that the concrete raw materials inside the mixing tank 2 cannot fall out of it in the reset state, ensuring that the mixing shaft 7 and the mixing block 8 can normally mix the concrete raw materials inside it.
[0033] See also Figure 1 - Figure 4A spring 23 is sleeved on the outside of the connecting rod 22, and the baffle 19 is connected to the fixed plate 20 by the spring 23. The inner diameter length of the scraper 15 is greater than the length of the multiple groups of stirring blocks 8. The spring 23 will continue to apply elastic force to the baffle 19, so that after the worker releases the pulling force on the handle 21, the spring 23 will reset the baffle 19 for the first time, preventing the worker from forgetting to close the baffle 19 and affecting the work progress during the addition of raw materials. The inner diameter of the scraper 15 is greater than the stirring block 8, so that the scraper 15 will not contact the stirring block 8 during the downward displacement process, ensuring that it can normally scrape off the residual concrete raw materials in the mixing tank 2, thereby increasing the service life of the equipment and reducing the work intensity of the workers.
[0034] The working principle of the utility model is as follows: when workers use the equipment to mix concrete raw materials, they need to put the concrete raw materials into the mixing tank 2, start the motor 10 to rotate the mixing shaft 7 to drive the mixing block 8 and the cleaning plate 18 to rotate together, so as to ensure the mixing effect and efficiency of the concrete. When the mixing is completed and the concrete raw materials in the mixing tank 2 need to be discharged, the workers only need to pull the handle 21, and drive the baffle 19 to move through the connecting rod 22, so as to discharge the concrete raw materials in the mixing tank 2 through the discharge port 24. After the discharge is completed, the workers move the cover plate 9 to make it convenient for the workers to add materials. During the movement of the cover plate 9, the gear 11 is driven to rotate by the rack 6, so that the rotating rod 12 rotates together, and then the belt 13 is used to drive the scraper 15 to move from top to bottom along the threaded rod 14, so as to push the concrete raw materials remaining on the inner wall of the mixing tank 2 and clean the inside thereof. The remaining concrete raw materials will fall to the bottom inclined surface of the mixing tank 2 under the push of the scraper 15 and the influence of gravity. The concrete inside the mixing tank 2 is discharged from the inside of the mixing tank 2 through the cooperation of the scraper 15 and the cleaning plate 18, effectively preventing the solidification of the concrete residue from affecting the mixing effect of the subsequent mixing equipment. After completing the operation, the worker releases the pulling force on the handle 21, and the spring 23 helps the baffle 19 to reset, and the worker can continue to add concrete raw materials for the next round of mixing of concrete.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
