Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a concrete raw material mixing device for building construction. Background Technology
[0002] Concrete raw material mixing equipment for construction is a type of equipment that thoroughly mixes raw materials such as cement, sand, and stone through a mixing host to produce concrete that can be used as structural materials for walls, foundations, etc. in construction.
[0003] Publication No. 202223181443.4 discloses a concrete mixing device for construction, including a box body. A mixing mechanism is provided on the top of the box body. A connecting pipe is connected to the bottom of the box body, and a conveying pipe is connected to the bottom of the connecting pipe. A first motor is fixedly connected to the right side of the conveying pipe, and a conveying rod is fixedly connected to the shaft of the first motor. A discharge pipe is connected to the bottom of the conveying pipe.
[0004] This concrete mixing device for construction uses a container to hold concrete raw materials. A mixing mechanism then mixes the concrete materials inside the container and facilitates the transfer of concrete materials from the connecting pipe to the conveying pipe. The conveying pipe, the first motor, and the conveying rod provide secondary mixing and facilitate concrete transport. This mixing device is less prone to clogging when discharging concrete and allows for convenient delivery to the desired location. However, the fixed position of the mixing rod results in a longer mixing time, reducing the equipment's mixing efficiency. Furthermore, the container is difficult for workers to disassemble, making internal cleaning challenging and increasing the difficulty of maintenance.
[0005] Therefore, those skilled in the art provide a concrete raw material mixing device for building construction to solve the problems mentioned in the background art. Utility Model Content
[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a concrete raw material mixing device for construction. The device utilizes a servo motor in the mixing mechanism to drive the sun gear to rotate. The meshing connection between the planetary gears, sun gear, and gear ring allows the fixed-point mixing rod and the traveling mixing rod to perform mixing, thus enhancing the mixing capacity. Furthermore, the connecting mechanism uses a locking rod to release the locking state of the connecting block, allowing the connecting block to slide against the fixed block, facilitating disassembly of the tank for cleaning.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] A concrete raw material mixing device for construction includes a lower tank, an upper tank, a connecting mechanism, a discharging mechanism, and a mixing mechanism. The connecting mechanism is provided at the upper end of the lower tank and includes four locking rods. The discharging mechanism is provided at the front end of the lower tank and includes a threaded rod. The mixing mechanism is provided inside the upper tank and includes two partitions and three planetary gears. A protective shell is fixedly connected to the center of the upper end of the upper tank. A servo motor is provided on the bottom surface inside the protective shell. The output shaft of the servo motor passes through the protective shell and is fixedly connected to a sun gear. The sun gear and planetary gears are rotatably connected to the partitions. The outer walls of the partitions are rotatably connected to the inner walls of the upper tank. A toothed ring is fixedly connected to the upper end of the inner wall of the upper tank. The toothed ring and the sun gear are meshed with the planetary gears. The lower end of the sun gear passes through the partitions and is fixedly connected to a fixed-point mixing rod. The lower ends of the planetary gears all pass through the partitions and are fixedly connected to a traveling mixing rod.
[0009] Through the above technical solution, the sun gear is driven to rotate by a servo motor, and the sun gear and the ring gear are meshed and connected by three planetary gears. This allows the fixed-point stirring rod, which is fixedly connected to the lower end of the sun gear, to stir at the center of the tank, while the wandering stirring rod, which is fixedly connected to the lower end of the planetary gears, can move around the center inside the tank and stir, thus enhancing the stirring capacity of the equipment.
[0010] Furthermore, a fixing block is fixedly connected to the lower end of the outer wall of the upper tank, and a sliding groove is opened inside the fixing block. A return spring is fixedly connected to the bottom surface of the sliding groove, and a sliding plate is fixedly connected to the upper end of the return spring. The center of the sliding plate is rotatably connected to the locking rod. A connecting block is fixedly connected to the upper end of the outer wall of the lower tank, and the connecting block is slidably connected to the fixing block. The upper end of the locking rod passes through the fixing block and is locked to the connecting block.
[0011] The above technical solution uses a reset spring acting on the slide plate to keep the lever engaged with the connecting block, connecting the upper and lower tanks. Pulling the lever releases the engagement with the connecting block, allowing the connecting block to slide with the fixed block, thus separating the upper and lower tanks and facilitating disassembly for internal cleaning.
[0012] Furthermore, a PLC control panel is fixedly connected to the lower end of one side of the outer wall of the lower tank, and support legs are fixedly connected to all four sides of the lower end of the lower tank.
[0013] The above technical solution allows operators to control the equipment's operation by using a PLC control panel fixedly connected to the lower tank, while the four support legs fixedly connected to the lower end of the lower tank provide stable support for the equipment, allowing it to be placed stably on the ground.
[0014] Furthermore, a discharge frame is connected through to the lower end of the outer wall of the front end of the lower tank, and support frames are fixedly connected to both sides of the upper middle part of the discharge frame. The lower end of the threaded rod is rotatably connected to the discharge frame, and a feed frame is connected through to the upper end of the outer wall of one side of the upper tank.
[0015] The above technical solution allows workers to easily add concrete raw materials such as cement, sand, and stone into the tank through the feed frame that runs through the upper tank body for mixing, while the support frame fixedly connected to the discharge frame provides support installation points for the threaded rod.
[0016] Furthermore, the upper end of the outer wall of the threaded rod is rotatably connected to the support frame, and a gate is threadedly connected to the middle of the outer wall of the threaded rod. The outer walls on both sides of the gate are slidably connected to the inner walls on both sides of the discharge frame.
[0017] The above technical solution allows the threaded rod and the gate to be connected by threads, enabling the operator to turn the threaded rod to move the gate within the discharge frame, thereby changing the size of the discharge channel and opening / closing the discharge frame.
[0018] Furthermore, all the sliding pieces slide inside the sliding groove, and the lower ends of all the locking rods penetrate through the sliding groove to the outside of the fixing block;
[0019] The above technical solution allows the lower end of the lever to pass through the slide groove to the outside of the fixed block, making it easier for workers to pull the lever to move the sliding plate within the slide groove and release the lever from the fixed connection of the lower tank body to the connecting block.
[0020] Furthermore, two limiting rods are fixedly connected to the upper edge of each clamping rod, and the outer wall of each limiting rod is slidably connected to the fixing block.
[0021] With the above technical solution, by sliding the two limiting rods fixedly connected to the clamp rod and the fixed block, after the clamp rod is pulled and the limiting rod slides out of the fixed block, the clamp rod is rotated by the sliding plate. The operator can rotate the clamp rod so that the limiting rod and the fixed block are pressed together, preventing the clamp rod from being pushed back by the return spring. This keeps the clamp rod separated from the connecting block, making it easier for the operator to disassemble the tank.
[0022] Furthermore, a sealing ring is fixedly connected to the upper edge of the lower tank body, and the upper end of the sealing ring is tightly fitted to the upper tank body;
[0023] The above technical solution, by using a sealing ring fixedly connected to the lower tank and tightly fitting it to the upper tank, improves the sealing performance between the tanks when the upper and lower tanks are connected, preventing liquid leakage.
[0024] This utility model has the following beneficial effects:
[0025] 1. The present invention proposes a concrete raw material mixing equipment for construction, which drives the sun gear to rotate through a servo motor in the mixing mechanism. The sun gear and the three planetary gears are meshed and connected to the sun gear and the gear ring, so that the fixed-point mixing rod fixedly connected to the lower end of the sun gear can mix at the center position of the tank, while the wandering mixing rod fixedly connected to the lower end of the planetary gear can move around the center position inside the tank and mix, thereby enhancing the mixing capacity and improving the mixing efficiency of the equipment.
[0026] 2. The concrete raw material mixing equipment for construction proposed in this utility model uses a return spring in the connecting mechanism to act on the sliding plate, keeping the clamping rod in a clamping state with the connecting block, thus connecting the upper tank and the lower tank. Pulling the clamping rod releases the clamping state with the connecting block, and the upper tank and the lower tank can be separated by the sliding connection between the connecting block and the fixed block. This makes it easier for workers to disassemble the tank for internal cleaning, reducing the difficulty of cleaning and maintenance work. Attached Figure Description

Detailed Implementation
[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0036] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 This utility model provides a specific embodiment: a concrete raw material mixing device for construction, including a lower tank 1, an upper tank 4, a connecting mechanism 5, a discharge mechanism 7, and a mixing mechanism 9. The upper end of the lower tank 1 is provided with the connecting mechanism 5, which includes four clamping rods 505. The front end of the lower tank 1 is provided with the discharge mechanism 7, which includes a threaded rod 703. The upper tank 4 is equipped with the mixing mechanism 9, which includes two partitions 903 and three planetary gears 905. A protective shell 901 is fixedly connected to the center of the upper end of the upper tank 4. The bottom of the protective shell 901... A servo motor 902 is provided on the surface. The output shaft of the servo motor 902 passes through the protective shell 901 and is fixedly connected to a sun gear 904. The sun gear 904 and planet gears 905 are rotatably connected to the partition plate 903. The outer wall of the partition plate 903 is rotatably connected to the inner wall of the upper tank 4. A gear ring 906 is fixedly connected to the upper end of the inner wall of the upper tank 4. The gear ring 906 and the sun gear 904 are meshed with the planet gears 905. The lower end of the sun gear 904 passes through the partition plate 903 and is fixedly connected to a fixed-point stirring rod 907. The lower ends of the planet gears 905 all pass through the partition plate 903 and are fixedly connected to a wandering stirring rod 908.
[0037] A PLC control panel 2 is fixedly connected to the lower end of one side outer wall of the lower tank 1. Support legs 3 are fixedly connected to all four sides of the lower end of the lower tank 1. The PLC control panel 2 fixedly connected to the lower tank 1 allows operators to control the equipment's operating status. The four support legs 3 fixedly connected to the lower end of the lower tank 1 provide stable support for the equipment, allowing it to be placed stably on the ground. A discharge frame 701 is continuously connected to the lower end of the front outer wall of the lower tank 1. Support frames 702 are fixedly connected to both sides of the upper middle part of the discharge frame 701. The lower end of the threaded rod 703 is rotatably connected to the discharge frame 701. A feed frame 8 is continuously connected to the upper end of one side outer wall of the upper tank 4. The feed frame 8, which is connected to the tank, allows workers to easily add concrete materials such as cement, sand, and stone into the tank for mixing. The support frame 702, which is fixedly connected to the discharge frame 701, provides a support mounting point for the threaded rod 703. The upper end of the outer wall of the threaded rod 703 is rotatably connected to the support frame 702. The middle of the outer wall of the threaded rod 703 is threadedly connected to the gate 704. The outer walls on both sides of the gate 704 are slidably connected to the inner walls on both sides of the discharge frame 701. By threading the threaded rod 703 and the gate 704, workers can turn the threaded rod 703 to move the gate 704 within the discharge frame 701, changing the size of the discharge channel and thus opening and closing the discharge frame 701.
[0038] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The lower ends of the outer walls of the upper tank 4 are all fixedly connected to fixing blocks 501. Each fixing block 501 has a sliding groove 502 inside. Each sliding groove 502 has a return spring 503 fixedly connected to the bottom surface inside. Each return spring 503 has a sliding piece 504 fixedly connected to the upper end. The center of each sliding piece 504 is rotatably connected to a locking rod 505. Each upper end of the outer walls of the lower tank 1 is fixedly connected to a connecting block 507. Each connecting block 507 is slidably connected to the fixing block 501. The upper end of each locking rod 505 passes through the fixing block 501 and is locked to the connecting block 507.
[0039] All sliding plates 504 slide inside the sliding groove 502, and the lower ends of the locking rods 505 pass through the sliding groove 502 to the outside of the fixing block 501. By allowing the lower ends of the locking rods 505 to pass through the sliding groove 502 to the outside of the fixing block 501, it is convenient for the operator to pull the locking rods 505 to drive the sliding plates 504 to move in the sliding groove 502, thereby releasing the locking state of the locking rods 505 on the connecting block 507 fixedly connected to the lower tank 1.
[0040] Two limiting rods 506 are fixedly connected to the upper edge of the clamping rod 505. The outer wall of the limiting rod 506 is slidably connected to the fixing block 501. By sliding the two limiting rods 506 fixedly connected to the clamping rod 505 to the fixing block 501, after the clamping rod 505 is pulled and the limiting rods 506 slide out of the fixing block 501, the sliding piece 504 is rotatably connected to the clamping rod 505. The operator can rotate the clamping rod 505 to make the limiting rods 506 abut against the fixing block 501, preventing the clamping rod 505 from being pushed back by the return spring 503. This keeps the clamping rod 505 separated from the connecting block 507, making it easy for the operator to disassemble the tank. A sealing ring 6 is fixedly connected to the upper edge of the lower tank 1. The upper end of the sealing ring 6 is tightly fitted to the upper tank 4. By tightly fitting the sealing ring 6 fixedly connected to the lower tank 1 and the upper tank 4, the sealing ring 6 can improve the sealing between the tanks when the upper tank 4 and the lower tank 1 are connected, preventing liquid leakage.
[0041] Working Principle: When using this concrete mixing equipment for construction, the operator first powers the equipment with an external power source, then uses the feed frame 8 to put concrete raw materials such as cement, sand, and stone into the tank. Next, the operator uses the PLC control panel 2 to start the servo motor 902 to drive the sun gear 904 to rotate. The meshing connection between the planetary gears 905, the sun gear 904, and the gear ring 906 causes the stationary mixing rod 907 to mix at the center of the tank, while the traveling mixing rod 908 moves around the center position inside the tank and mixes the materials. After the mixing is completed, the staff will turn the threaded rod 703 to move the gate 704 and discharge the concrete from the discharge frame 701. Then, pull the clamping rod 505 to release the clamping state of the connecting block 507. The connecting block 507 and the fixed block 501 will slide to separate the upper tank 4 and the lower tank 1 for cleaning and maintenance. Then, the connecting block 507 will be inserted into the fixed block 501. The return spring 503 will act on the sliding plate 504 to keep the clamping rod 505 in the clamping state of the connecting block 507, thus connecting the upper tank 4 and the lower tank 1.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features.
