Description

Technical Field

[0001] This utility model belongs to the field of concrete block production technology, and in particular relates to a batching and mixing equipment for concrete block production. Background Technology

[0002] Concrete block production batching and mixing equipment is a specialized device used to weigh, convey, and thoroughly mix concrete raw materials such as cement, sand, gravel, water, and additives according to precise proportions to form a uniform and stable concrete mixture. It includes core components such as batching scales, screw conveyors, mixers, and control systems. This equipment is used in concrete block production because only through precise batching to ensure the raw material ratios meet process requirements, and then through efficient mixing to ensure uniform integration of all components, can the concrete mixture possess consistent fluidity, strength, and other properties. This provides a stable raw material base for subsequent block forming and curing processes, preventing quality problems such as insufficient strength and cracking caused by imbalanced proportions or uneven mixing. Simultaneously, it improves production efficiency and automation levels.

[0003] However, in the existing equipment, after the material is mixed and enters the feeding stage, due to the lack of necessary screening steps, the impurities and lumps contained in the mixture are not easy to be effectively separated. These unremoved impurities and lumps will directly enter the subsequent processes, which will have an adverse effect on product quality, production efficiency or equipment operation stability. Utility Model Content

[0004] The purpose of this utility model is to provide a batching and mixing equipment for concrete block production. By setting up a screening section, it solves the problem that after the material is mixed and enters the feeding stage, due to the lack of necessary screening processing steps, the impurities and lumps contained in the mixture are not easy to be effectively separated. These unremoved impurities and lumps will directly enter the subsequent processes, which will have an adverse effect on product quality, production efficiency or equipment operation stability.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a batching and mixing equipment for concrete block production, comprising a mixing chamber and a screening section disposed at the bottom of the mixing chamber. The mixing section is disposed within the mixing chamber. The screening section includes a U-shaped frame fixedly connected to the bottom of the mixing chamber, with a screen rotatably connected to the U-shaped frame. A rectangular frame is disposed at the bottom of the mixing chamber, with a motor fixedly connected to the front of the rectangular frame. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. A rotating shaft is rotatably connected to the rectangular frame. A crankshaft connecting rod is fixedly connected to one end of the rotating shafts, which are close to each other. The bottom of the screen is fixedly connected to the U-shaped frame. The end of the crankshaft connecting rod away from the rotating shaft is hinged to the U-shaped frame. A balancing component is disposed on the rectangular frame. The rotating shaft passes through the rectangular frame and is rotatably connected to it.

[0007] Furthermore, the mixing section includes a mixing assembly installed inside a mixing chamber, and a protective assembly installed on top of the mixing chamber, wherein the protective assembly is used in conjunction with the mixing assembly.

[0008] Furthermore, the mixing assembly includes a hopper fixedly connected to the top of the mixing chamber. Rotary shafts three and four are rotatably connected inside the mixing chamber, with both ends extending outside the mixing chamber. Helical blades are provided on the outer walls of both shafts three and four. A driving component is provided on shaft three, and a transmission component is provided on shafts three and four. The hopper communicates with the mixing chamber. This design, through the opposing or reverse rotation of the double helical blades, enables efficient mixing and conveying of materials, improving mixing uniformity. The transmission component links the two shafts, reducing energy consumption. The interconnected structure between the hopper and the mixing chamber simplifies the feeding process, reduces material residue, and improves production efficiency.

[0009] Furthermore, the protective assembly includes a mounting groove on the front of the mixing chamber, a protective cover slidably connected to the inner wall of the mounting groove, a limit rod fixedly connected to the front of the protective cover, a sliding rod fixedly connected to the front of the mixing chamber, a stop block fixedly connected to the front end of the sliding rod, and a reset component provided on the outer wall of the sliding rod. This design enables convenient opening and closing of the mixing chamber by sliding the protective cover, the cooperation between the limit rod and the sliding rod ensures stable sliding of the protective cover, and the reset component allows the protective cover to automatically reset after operation, effectively preventing dust and foreign objects from entering the mixing chamber, ensuring the safety of the internal equipment, extending its service life, and improving operational convenience and production safety.

[0010] Furthermore, the balancing component includes a connecting plate fixedly connected to the back of the rectangular frame. The front of the connecting plate is fixedly connected to the mixing box. Several guide rods are fixedly connected to the bottom of the screen. All of the guide rods pass through the rectangular frame and are slidably connected to the rectangular frame. There are four guide rods. This design achieves a stable connection between the rectangular frame and the mixing box through the connecting plate. The four guide rods provide uniform support and guidance for the screen, ensuring that the screen remains balanced and stable during vibration or movement, preventing tilting or deviation, improving screening efficiency and accuracy, extending equipment service life, and reducing maintenance costs.

[0011] Furthermore, the driving component includes a motor sleeve fixedly connected to the right side of the mixing tank. A second motor is mounted on the motor sleeve, and the output shaft of the second motor is fixedly connected to a third rotating shaft via a coupling. This design provides stable support and protection for the motor through the motor sleeve, and the coupling enables efficient power transmission, allowing the second motor to directly drive the third rotating shaft to rotate. The design is compact, has high transmission efficiency, reduces energy loss, and facilitates the installation, disassembly, and maintenance of the motor, thereby improving the stability and reliability of the equipment operation.

[0012] Furthermore, the transmission component includes gears that are both sleeved on the outer walls of rotating shaft three and rotating shaft four. The two gears mesh with each other, and both gears are located on the left side of rotating shaft three and rotating shaft four. This design achieves synchronous reverse rotation of the two rotating shafts through gear transmission, so that the spiral blades form opposite or reverse material conveying and mixing actions, thereby enhancing the stirring effect and improving the mixing uniformity.

[0013] Furthermore, the reset component includes a slide plate slidably connected to the outer wall of the slide rod, the front end of the limiting rod extends into the slide plate and is slidably connected to the slide plate, and a spring is wound around the outer wall of the slide rod; wherein, one end of the spring is fixedly connected to the stop block, and the other end of the spring is fixedly connected to the slide plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a screening section, the mixture conveyed by the spiral blades flows into the screen through the discharge port. The screen can effectively screen out impurities and lumps, allowing the mixture that meets the particle size requirements to pass through. The intercepted impurities and lumps are shaken off and collected in the waste bin. At the same time, motor one is started, which drives the crankshaft connecting rod to rotate through shaft one and shaft two. With the hinge between the crankshaft connecting rod and the U-shaped frame two at the bottom of the screen, the screen vibrates up and down, thereby preventing the mesh from clogging and ensuring continuous and stable screening and screening effect.

[0016] 2. By setting up a mixing section, when in use, the raw materials are put into the hopper and introduced into the mixing box. The motor is started to drive the rotating shaft three to rotate. With the meshing transmission of the gears on the rotating shaft three and the rotating shaft four, the two rotating shafts can drive the spiral blades to rotate relative to each other in sync. While fully mixing the raw materials in the box, the spiral structure of the spiral blades is used to synchronously and directionally transport the mixed raw materials, thereby realizing the integrated operation of raw material mixing and transportation, which greatly improves processing efficiency.

The mixture conveyed by the spiral blades 314 through the screening section 2 flows into the screen 212 through the discharge port 315. The screen can effectively screen impurities and lumps, allowing the mixture that meets the particle size requirements to pass through. The intercepted impurities and lumps are shaken off and collected in the waste bin. At the same time, the motor 214 is started, which drives the crankshaft connecting rod 217 to rotate through the rotating shaft 215 and the rotating shaft 216. With the hinge between the crankshaft connecting rod and the U-shaped frame 218 at the bottom of the screen, the screen vibrates up and down, thereby preventing the mesh from clogging and ensuring continuous and stable screening and screening effect.

Spiral blades 314 are provided on the outer walls of the third rotating shaft 312 and the fourth rotating shaft 313. A spiral blade 314 is provided on the third rotating shaft 312. The drive unit includes a transmission component on shaft 312 and shaft 313. The hopper 311 communicates with the mixing chamber 1. The protective assembly 32 includes a mounting groove 321 on the front of the mixing chamber 1. A protective cover 322 is slidably connected to the inner wall of the mounting groove 321. A limit rod 323 is fixedly connected to the front of the protective cover 322. A sliding rod 324 is fixedly connected to the front of the mixing chamber 1. A stop block 325 is fixedly connected to the front end of the sliding rod 324. A reset component is provided on the outer wall of the sliding rod 324. The drive unit includes a motor sleeve 316 fixedly connected to the right side of the mixing chamber 1. The motor sleeve 316 is equipped with... There is a second motor 317, whose output shaft is fixedly connected to a third shaft 312 via a coupling. The transmission components include gears 318 that are both sleeved on the outer walls of the third shaft 312 and the fourth shaft 313, and the two gears 318 mesh with each other. Both gears 318 are located on the left side of the third shaft 312 and the fourth shaft 313. The reset component includes a sliding plate 326 that is slidably connected to the outer wall of a sliding rod 324. The front end of a limiting rod 323 extends into the sliding plate 326 and is slidably connected to the sliding plate 326. A spring 327 is wound around the outer wall of the sliding rod 324. One end of the spring 327 is connected to a stop. Block 325 is fixedly connected, and the other end of spring 327 is fixedly connected to slide plate 326. By setting up mixing section 3, when in use, after the raw material is put into hopper 311 and introduced into mixing box 1, motor 2 317 is started to drive shaft 312 to rotate. With the meshing transmission of gear 318 on shaft 3 and shaft 4 313, the two shafts can synchronously drive the spiral blades 314 to rotate relative to each other. While fully stirring and mixing the raw material in the box, the spiral structure of the spiral blades is used to synchronously and directionally transport the mixed raw material, thereby realizing the integrated operation of raw material mixing and transportation, and greatly improving processing efficiency.

[0031] One specific application of this embodiment is as follows: During use, the raw materials to be mixed can be placed together into hopper 311 and then fed into mixing chamber 1. Subsequently, motor 2 317 is started, driving shaft 312 to rotate. Since gear 318 on shaft 312 meshes with gear 318 on shaft 4 313, during the rotation of shaft 312, the meshing transmission of the two gears 318 allows shafts 312 and 4 313 to synchronously drive their spiral blades 314 to rotate relative to each other, thus mixing the multiple components in mixing chamber 1. The raw materials are thoroughly mixed. Due to the spiral structure of the spiral blades 314, the mixed materials can be simultaneously and directionally conveyed during the mixing process. This configuration enables integrated operation of raw material mixing and conveying, significantly improving processing efficiency. The mixture conveyed by the spiral blades 314 flows into the screen 212 through the discharge port 315. The screen 212 can effectively screen out impurities and lumps in the mixture. The mixture that meets the particle size requirements can pass smoothly through the screen 212 and be screened, while impurities and undissolved raw material lumps are filtered out by the screen. Screen 212 intercepts and shakes the material into a waste bin for centralized collection. Simultaneously, during the screening process of screen 212, motor 214 can be started. Motor 214 drives crankshaft connecting rod 217 to rotate via shaft 215 and shaft 216. Since the other end of crankshaft connecting rod 217 is hinged to the U-shaped frame 218 at the bottom of screen 212, during the operation of motor 214, the coordinated action of shaft 215, shaft 216, and crankshaft connecting rod 217 causes screen 212 to vibrate up and down. This design effectively prevents material from being screened. The screen mesh 212 is blocked to ensure a continuous and stable screening process and guarantee the screening effect. When it is necessary to clean the inside of the mixing box 1 or replace parts, the slide plate 326 can be pulled outward to release its lock on the upper limit rod 323 of the protective cover 322, so that the protective cover 322 can be easily opened, which is convenient for operators to carry out internal cleaning or maintenance. At the same time, as the slide plate 326 moves outward, it will also compress the spring 327 on the outer wall of the slide rod 324, so that it accumulates elastic potential energy, providing power support for the automatic reset of the slide plate 326.
