Description

Technical Field

[0001] This invention relates to the field of mixer technology, specifically to a cement mortar mixer for concrete production. Background Technology

[0002] To fairly and accurately compare the quality and performance of different cements globally, variables in the testing process must be eliminated. A crucial element of this is the preparation of test samples (cement mortar blocks), and cement mortar mixers are designed to achieve this standardization. It operates strictly according to international (such as ISO 679) and national (such as China's GB / T17671) standards, ensuring that the time, speed, sequence, and method of each mixing are completely consistent. It conducts quality inspections on cement leaving the factory to ensure that products meet national standards and customer requirements, performs acceptance inspections on cement entering the factory to ensure the quality of concrete production, conducts quality sampling or arbitration inspections on cement used on-site, conducts cement material research, new formula development, and admixture evaluation, and performs third-party certification, arbitration inspections, and market sampling. It has extremely strict regulations on mixing speed (low / high speed), mixing time (accurate to the second for each stage), and the order of adding materials (water -> cement -> standard sand). The prepared cement mortar must be highly uniform, without clumping or segregation; otherwise, it will seriously affect the subsequent specimen molding and strength test results. Mortar prepared using the same standard in the laboratory, by different operators, and at different times should have comparable performance (final strength). Specialized mixers are key equipment for achieving this comparability. Although they mix mortar (cement + standard sand + water), their mixing state (shear force, mixing effect) is designed to simulate the process of cement paste encapsulating aggregate in concrete, providing a basis for testing the cementitious ability of cement.

[0003] The operator needs to add standard sand evenly to the mixing pot at a specified time. The speed, uniformity, and timing of this action depend entirely on the operator's manual operation, which is one of the biggest sources of human error in the process. Lack of proficiency or non-standard operation will directly affect the quality of the mortar. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cement mortar mixer for concrete production, comprising a fixed base, a lower tank fixedly connected to the top of the fixed base, an upper tank fixedly connected to the top of the lower tank, a feeding device fixedly connected to the side of the upper tank, a motor fixedly connected to the top of the upper tank, a transmission assembly fixedly connected to the drive shaft of the motor, a mixing assembly fixedly connected to the bottom of the transmission assembly, a discharge assembly fixedly connected to the bottom of the lower tank, and a spraying assembly fixedly connected to the inner side of the upper tank.

[0005] The feeding device includes a screw ring and a tapered tube. A connecting rod is fixedly connected to the bottom of the screw ring, and a sliding plate is fixedly connected to the end of the connecting rod away from the screw ring. A guide assembly is connected to the top of the tapered tube. The screw ring is sleeved on the side of the transmission assembly and threadedly connected to the side of the transmission assembly. The side of the sliding plate contacts the inner wall of the upper tank. The tapered tube is located on the side of the upper tank at a position off-center.

[0006] Preferably, the guiding component includes a feed pipe with a flow-stopping ring fixedly connected to its inner wall. The bottom of the feed pipe is connected to the top of the conical tube. The rotation of the motor's drive shaft drives the transmission component to rotate, which in turn moves the screw ring. The movement of the screw ring moves the connecting rod, which in turn moves the sliding plate. Standard sand is fed into the feed pipe and accumulates inside the conical tube. The sliding plate restricts the outlet of the conical tube, preventing premature feeding of raw materials. During the upward movement of the screw ring, the rotation cycle of the motor is used for timing, ensuring that the raw materials are fed at a fixed time after a specified rotation cycle. When the sliding plate moves, the raw materials inside the conical tube are fed into the tube along the direction of mixing, which facilitates the feeding of raw materials along the direction of mixing and facilitates mixing with the mortar. The flow-stopping ring ensures unidirectional feeding of the raw materials, preventing backflow during mixing.

[0007] Preferably, the transmission assembly includes a transmission shaft, a protruding thread fixedly connected to the side of the transmission shaft, a sliding ring provided at the top of the transmission shaft, the top of the sliding ring being fixedly connected to the drive shaft of the motor, the bottom of the transmission shaft being fixedly connected to the top of the stirring assembly, and a threaded ring sleeved on the side of the transmission shaft and threadedly connected to the transmission shaft through the protruding thread.

[0008] Preferably, the stirring assembly includes a fixed frame, a reinforcing bracket fixedly connected to the side of the fixed frame, a helical blade fixedly connected to the bottom of the fixed frame, guide vanes fixedly connected to the side of the helical blade, a groove formed at the bottom of the helical blade, a fixed top of the fixed frame fixedly connected to the bottom of the drive shaft, and the side of the groove contacting the inner wall of the outlet assembly. The rotation of the motor's drive shaft drives the drive shaft to rotate, which in turn drives the fixed frame to rotate. The rotation of the fixed frame drives the helical blade to rotate, which in turn moves the guide vanes. Thus, under the action of the helical blade, an upward force is provided to the fluid, causing the fluid to move upward along the helical blade, thereby facilitating the mixing and stirring of the internal fluid, and the guide vanes drive the fluid from the inside out. The flow facilitates the mixing of external raw materials with those in the mixing center, ensuring uniform mixing. After mixing, the motor drive shaft rotates in the opposite direction, causing the spiral blades to move in the opposite direction. This, in turn, engages with the discharge assembly via a chute, applying downward pressure to the fluid through the spiral blades, thus facilitating fluid discharge. This ensures both uniform mixing and easy material discharge. Simultaneously, the rotation of the drive shaft drives the convex thread to rotate, which in turn moves the spiral ring, causing it to rise. When the spiral ring rises to the side of the sliding ring, it disengages from the convex thread, making contact with the side of the sliding ring. This does not affect the normal rotation of the drive shaft, achieving precise timing without disrupting normal mixing.

[0009] Preferably, the outlet component includes a conical conduit, with a connecting plate fixedly connected to the top of the conical conduit and a guide pipe connected to the bottom of the conical conduit. A threaded cap is threadedly connected to the side of the guide pipe, and the top of the conical conduit is connected to the bottom of the lower tank. During stirring, the spiral blades scrape the inner wall of the conical conduit along the inside of the conical conduit via a sliding groove, thereby driving the raw material upward, which facilitates uniform mixing of the raw material. The conical design of the conical conduit facilitates the concentration of fluid, thus facilitating the discharge of the raw material. At the same time, the threaded connection between the threaded cap and the guide pipe facilitates the smooth discharge of fluid. Furthermore, the threaded connection between the guide pipe and the threaded cap facilitates cleaning of the inside of the tank, thus facilitating multiple stirring operations. The connecting plate facilitates the concentration of raw material, thereby facilitating the concentration of water flow inside the tank.

[0010] Preferably, the spraying assembly includes a fixed bracket, a water inlet pipe is fixedly connected to the top of the fixed bracket, a water inlet connector is connected to the top of the fixed bracket, a nozzle is connected to the bottom side of the fixed bracket, the top center of the fixed bracket is fixedly connected to the bottom of the motor, and the drive shaft of the motor passes through the top of the fixed bracket and is rotatably connected to the fixed bracket.

[0011] Preferably, the upper tank includes an outer shell, the top of which has a sliding hole adapted to the sliding plate, the inner wall of which is fixedly connected to a limiting seat adapted to the sliding plate, the inner wall of which is fixedly connected to the side of a fixed bracket, the bottom of which is fixedly connected to the top of the lower tank, and the water inlet is connected to the water inlet connector. Water is poured in along the water inlet connector and guided along the water inlet pipe, so that the water is sprayed out along the nozzle, thereby driving the water to spray out along the nozzle. This allows multiple sets of water to spray out along the nozzle, thus creating a barrier and preventing the raw materials from flying during the introduction process. The uniform spraying of water facilitates the mixing of raw materials and water compared to the traditional direct injection method, thus facilitating the rapid molding of mortar. The sliding hole allows the sliding plate to extend and move, while the limiting seat (upper tank shell) limits the movement trajectory of the sliding plate, allowing the sliding plate to move along the outlet of the tapered tube, thus facilitating the addition of raw materials.

[0012] This invention provides a cement mortar mixer for concrete production. It has the following beneficial effects:

[0013] 1. This cement mortar mixer for concrete production is equipped with a screw ring. The rotation of the motor's drive shaft drives the transmission assembly to rotate, which in turn moves the screw ring. The movement of the screw ring moves the connecting rod, which in turn moves the sliding plate. Standard sand is fed in along the feed pipe and accumulates inside the conical tube. The sliding plate restricts the outlet of the conical tube, preventing premature feeding of raw materials. During the upward movement of the screw ring, the rotation cycle of the motor is used for timing, ensuring that the raw materials are fed at a fixed time after a specified rotation cycle. When the sliding plate moves, the raw materials inside the conical tube are fed in along the conical tube, with the feeding direction facing the mixing direction. This facilitates the feeding of raw materials along the mixing direction, making it easier to mix with the mortar. The flow-stopping ring ensures one-way flow of the raw materials, preventing backflow during mixing.

[0014] 2. This cement mortar mixer for concrete production is equipped with a fixed frame. The rotation of the motor's drive shaft drives the transmission shaft to rotate, which in turn drives the fixed frame to rotate. The rotation of the fixed frame drives the spiral blades to rotate, which in turn drives the guide blades to move. Under the action of the spiral blades, an upward force is provided to the fluid, causing the fluid to move upward along the spiral blades, thus facilitating the mixing of the internal fluid. The guide blades also drive the fluid to flow from the inside out, facilitating the mixing of external raw materials with the raw materials in the mixing center, thus ensuring uniform mixing. After mixing, the motor's drive shaft rotates in the opposite direction, causing the spiral blades to move in the opposite direction. This, in turn, engages with the discharge assembly through a chute, providing a downward pressure on the fluid through the spiral blades, facilitating fluid discharge. This ensures both uniform mixing and easy material discharge. Simultaneously, the rotation of the transmission shaft drives the convex thread to rotate, which in turn drives the screw ring to move, causing the screw ring to rise. When the screw ring rises to the side of the sliding ring, it disengages from the convex thread, thus contacting the side of the sliding ring. This does not affect the normal rotation of the transmission shaft, thus achieving precise timing without affecting normal mixing.

[0015] 3. This cement mortar mixer for concrete production is equipped with spiral blades. During mixing, the spiral blades scrape the inner wall of the conical guide tube along the groove, thereby moving the raw materials upwards. This facilitates uniform mixing of the raw materials. The conical design of the guide tube facilitates fluid concentration, which in turn facilitates the discharge of raw materials. The threaded connection between the threaded cap and the guide tube facilitates smooth fluid discharge. Furthermore, the threaded connection between the guide tube and the threaded cap facilitates cleaning of the tank interior, enabling multiple mixing cycles. The connecting plate facilitates the concentration of raw materials, which in turn facilitates the concentration of water flow inside the tank.

[0016] 4. This cement mortar mixer for concrete production is equipped with a water inlet connector. When the water inlet connector is connected, water is poured in along the connector and guided along the inlet pipe, causing the water to be sprayed out along the nozzle. This results in multiple water streams being sprayed out along the nozzle, creating a barrier to prevent raw materials from flying during the introduction process. The uniform spraying of water facilitates the mixing of raw materials and water compared to traditional direct injection methods, thus facilitating rapid mortar formation. The sliding plate extends and moves through a sliding hole, while the movement trajectory of the sliding plate is limited by a limiting seat, allowing the sliding plate to move along the outlet of the conical tube, thus facilitating the addition of raw materials.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-3The present invention provides a technical solution: a cement mortar mixer for concrete production, comprising a fixed base 7, a lower tank 9 fixedly connected to the top of the fixed base 7, an upper tank 1 fixedly connected to the top of the lower tank 9, a feeding device 2 fixedly connected to the side of the upper tank 1, a motor 3 fixedly connected to the top of the upper tank 1, a transmission assembly 4 fixedly connected to the drive shaft of the motor 3, a mixing assembly 5 fixedly connected to the bottom of the transmission assembly 4, an outlet assembly 6 fixedly connected to the bottom of the lower tank 9, and a spraying assembly 8 fixedly connected to the inner side of the upper tank 1.

[0029] Standard sand is introduced through the feeding device 2. The motor 3 is started, and the drive shaft of the motor 3 rotates, driving the transmission component 4 to rotate. The rotation of the transmission component 4 drives the mixing component 5 to rotate, which in turn drives the water and mortar to mix. During the rotation of the transmission component 4, the feeding device 2 is moved, and the corresponding component of the feeding device 2 is moved during a certain mixing time. This movement is achieved by rotating the transmission component 4 in cycles, allowing for feeding at fixed times. This reduces the time error of manual feeding and the test error of the standard sand. The rotation of the mixing component 5 drives the fluid to move centripetally and mix. At the same time, the blade angle of the mixing component 5 provides an upward force to the fluid, causing it to move upward and ensuring uniform mixing, thus guaranteeing the quality of the mixing.

[0030] The feeding device 2 includes a screw ring 201 and a tapered tube 204. A connecting rod 202 is fixedly connected to the bottom of the screw ring 201. A sliding plate 203 is fixedly connected to the end of the connecting rod 202 away from the screw ring 201. A guide component 205 is connected to the top of the tapered tube 204. The screw ring 201 is sleeved on the side of the transmission component 4 and threadedly connected to the side of the transmission component 4. The side of the sliding plate 203 contacts the inner wall of the upper tank 1. The tapered tube 204 is located on the side of the upper tank 1 at a position off-center.

[0031] The guide assembly 205 includes a feed pipe 2051, with a flow stop ring 2052 fixedly connected to the inner wall of the feed pipe 2051, and the bottom of the feed pipe 2051 communicating with the top of the tapered pipe 204.

[0032] The drive shaft of motor 3 rotates, causing transmission component 4 to rotate. The rotation of transmission component 4 causes screw ring 201 to move. The movement of screw ring 201 causes connecting rod 202 to move. The movement of connecting rod 202 causes sliding plate 203 to move, feeding standard sand along feed pipe 2051. The sand accumulates inside conical tube 204, and the outlet of conical tube 204 is restricted by sliding plate 203 to prevent premature feeding of raw materials. During the upward movement of screw ring 201, the rotation cycle of motor 3 is used for time positioning to ensure that the raw materials are fed at a fixed time after a specified rotation cycle. When sliding plate 203 moves, the raw materials inside conical tube 204 are fed along conical tube 204, and the feeding direction of conical tube 204 is towards the stirring direction, which facilitates the feeding of raw materials along the stirring direction, making it easier to mix with mortar. The flow-stopping ring 2052 ensures one-way introduction of raw materials, thereby preventing backflow during the stirring process.

[0033] Please see Figures 1-6 The present invention provides a technical solution: the transmission assembly 4 includes a transmission shaft 401, a protruding thread 402 is fixedly connected to the side of the transmission shaft 401, a sliding ring 403 is provided on the top of the transmission shaft 401, the top of the sliding ring 403 is fixedly connected to the drive shaft of the motor 3, the bottom of the transmission shaft 401 is fixedly connected to the top of the stirring assembly 5, and a threaded ring 201 is sleeved on the side of the transmission shaft 401 and threadedly connected to the transmission shaft 401 through the protruding thread 402.

[0034] The stirring assembly 5 includes a fixed frame 501, a reinforcing bracket 502 fixedly connected to the side of the fixed frame 501, a spiral blade 503 fixedly connected to the bottom of the fixed frame 501, a guide blade 504 fixedly connected to the side of the spiral blade 503, a groove 505 opened at the bottom of the spiral blade 503, the top of the fixed frame 501 fixedly connected to the bottom of the drive shaft 401, and the side of the groove 505 in contact with the inner wall of the discharge assembly 6.

[0035] The rotation of the drive shaft of motor 3 drives the transmission shaft 401 to rotate, which in turn drives the fixed frame 501 to rotate. The rotation of the fixed frame 501 drives the spiral blades 503 to rotate, which in turn drives the guide blades 504 to move. Under the action of the spiral blades 503, an upward force is provided to the fluid, causing the fluid to move upwards along the spiral blades 503. This facilitates the mixing and stirring of the internal fluid. The guide blades 504 also drive the fluid to flow from the inside out, facilitating the mixing of external raw materials with the raw materials at the mixing center, thus ensuring uniform mixing. After mixing is complete, the drive shaft of motor 3 rotates in the opposite direction, thereby driving the spiral blades 503... The reverse movement allows the fluid to engage with the discharge component 6 via the chute 505, thereby providing downward pressure to the fluid through the spiral blades 503. This facilitates fluid discharge, ensuring both uniform mixing and easy material discharge. Simultaneously, the rotation of the drive shaft 401 drives the convex thread 402 to rotate, which in turn moves the screw ring 201, causing it to rise. When the screw ring 201 rises to the side of the sliding ring 403, it disengages from the convex thread 402, bringing it into contact with the side of the sliding ring 403. This does not affect the normal rotation of the drive shaft 401, thus achieving precise timing without disrupting normal mixing.

[0036] Please see Figures 1-7 The present invention provides a technical solution: the export component 6 includes a tapered conduit 601, a connecting plate 602 is fixedly connected to the top of the tapered conduit 601, a guide pipe 603 is connected to the bottom of the tapered conduit 601, a threaded cap 604 is threadedly connected to the side of the guide pipe 603, and the top of the tapered conduit 601 is connected to the bottom of the lower tank 9.

[0037] During stirring, the spiral blades 503 scrape the inner wall of the conical conduit 601 along the groove 505, thereby moving the raw materials upward and facilitating uniform mixing. The conical design of the conical conduit 601 facilitates fluid concentration and raw material discharge. The threaded connection between the threaded cap 604 and the guide pipe 603 facilitates smooth fluid discharge. The threaded connection between the guide pipe 603 and the threaded cap 604 also facilitates cleaning of the tank interior, enabling repeated stirring. The connecting plate 602 facilitates the concentration of raw materials and the concentration of water flow inside the tank.

[0038] Please see Figures 1-9The present invention provides a technical solution: the spraying assembly 8 includes a fixed bracket 801, a water inlet pipe 802 is fixedly connected through and fixed to the top of the fixed bracket 801, a water inlet connector 803 is connected to the top of the fixed bracket 801, a nozzle 804 is connected to the bottom of the side of the fixed bracket 801, the top center position of the fixed bracket 801 is fixedly connected to the bottom of the motor 3, and the drive shaft of the motor 3 passes through the top of the fixed bracket 801 and is rotatably connected to the fixed bracket 801.

[0039] The upper tank 1 includes an upper tank shell 101. The top of the upper tank shell 101 is provided with a sliding hole 102 that is adapted to the sliding plate 203. The inner wall of the upper tank shell 101 is fixedly connected with a limiting seat 103 that is adapted to the sliding plate 203. The inner wall of the upper tank shell 101 is fixedly connected to the side of the fixed bracket 801. The bottom of the upper tank shell 101 is fixedly connected to the top of the lower tank 9.

[0040] When the water inlet connector 803 is connected, water is poured in along the water inlet connector 803 and guided along the water inlet pipe 802, causing the water to be sprayed out along the nozzle 804. This causes multiple sets of water to be sprayed out along the nozzle 804, thus creating a barrier and preventing the raw materials from flying during the introduction process. The uniform spraying of water facilitates the mixing of raw materials and water compared to the traditional direct injection method, thereby facilitating the rapid molding of mortar. The sliding plate 203 is extended and moved by the sliding hole 102, and the movement trajectory of the sliding plate 203 is limited by the limiting seat 103, so that the sliding plate 203 moves along the outlet of the tapered pipe 204, thereby facilitating the addition of raw materials.

[0041] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
