Description

Technical Field

[0001] This utility model belongs to the field of concrete mortar mixing technology, specifically relating to a concrete mortar batching device. Background Technology

[0002] Equipment for preparing concrete and mortar in the construction industry aims to improve production efficiency and product quality by mechanizing the mixing, stirring, and conveying of raw materials. As a fundamental material in building construction, the accuracy and uniformity of concrete mortar mix proportions directly affect the safety and durability of engineering projects. Therefore, technological development in this field focuses on automation, precision control, and pollution-prevention design.

[0003] In the development of concrete mortar mixing devices, traditional equipment often suffers from problems such as inaccurate weighing, interference from mixing vibrations, and complex structures. For example, taking the patent "A Concrete Mortar Mixing Device" (publication number CN 219726781 U) as an example, this device uses baffles and baffle units to prevent material splashing and adhering to the discharge end of the screw conveyor, providing a certain degree of pollution prevention. However, this patent has significant shortcomings: it does not integrate a weighing system, and the raw material ratio relies on manual labor or external weighing equipment, making it prone to inaccurate ratios due to errors during transportation and material feeding. While some industry-integrated weighing and mixing functions exist, the mixing and weighing functions are not separated. Strong vibrations during mixing are directly transmitted to the weighing sensor, causing reading drift and affecting accuracy. Furthermore, existing mixing devices with weighing functions have relatively simple structures and lack lifting and locking mechanisms, making it impossible to avoid interference from mixing during weighing, thus limiting their application in high-end construction.

Between the mixing and batching assembly and the batching base plate 1; a discharge assembly, which is located on the lower wall of the mixing and batching assembly; two limiting slide assemblies including: a limiting lifting platform 2, which is fixedly located on the upper wall of the batching base plate 1; and a limiting slide 3, which is fixedly located on the upper wall of the limiting lifting platform 2. The upper walls of the two limiting lifting platforms 2 are respectively provided with lifting hydraulic devices 14, and the driving ends of the two lifting hydraulic devices 14 are provided with anti-slip pads. The batching base plate 1 is provided with a clearance groove, and the lower wall of the batching base plate 1 is provided with four shock-absorbing feet.

[0019] As a preferred embodiment, the two high-position limiting components further include: a high-position limiting hydraulic device 4, which is fixedly mounted on the outer wall of the limiting slide 3 by a bracket; and a high-position limiting baffle 5, which is movably mounted in the slot of the limiting slide 3, with the drive end of the high-position limiting hydraulic device 4 connected to the high-position limiting baffle 5.

[0020] As a preferred embodiment, the mixing assembly further includes: two mixing tank limiting sliders 6, which are movably disposed inside the limiting slide rails 3; a mixing tank body 7, which is fixedly disposed between the two mixing tank limiting sliders 6, and a discharge hole is provided on the lower wall of the mixing tank body 7; a stirring screw plate 8, which is provided with a bracket inside the mixing tank body 7, and both ends of the stirring screw plate 8 are movably disposed inside the mixing tank body 7 through bearings; and a stirring motor 9, which is disposed on the lower wall of the mixing tank body 7 through a bracket, and the drive end of the stirring motor 9 is connected to the stirring screw plate 8.

[0021] As a preferred embodiment, the weighing assembly further includes: a pressure sensor 10, which is disposed on the upper wall of the batching base plate 1; and a tank support platform 11, which is disposed on the lower wall of the mixing tank body 7.

[0022] As a preferred embodiment, the discharge assembly further includes: a discharge pipe 12, one end of which is fixedly installed in the discharge hole of the mixing tank body 7; an electrically controlled valve 13, which is installed outside the discharge pipe 12; and a discharge hose 15 at the tail end of the discharge pipe 12.

[0023] Working principle: Before using this device, the operator first connects an external AC power source to the device to provide power to the electrical equipment in the device, then connects an external hydraulic power source to the device to provide power to the hydraulic equipment in the device, and finally connects a matching controller to the device to provide control and working logic for the power components in the device.

[0024] In the initial position, the high-position limiting hydraulic device 4 retracts, and its driving end drives the high-position limiting baffle 5 to the yielding state, lifting the hydraulic device 14 to retract. At this time, the two mixing tank limiting sliders 6 are in the low position inside the limiting slide 3, which also drives the mixing tank body 7 to the low position, and makes the tank support platform 11 installed below the mixing tank body 7 above the pressure sensor 10. At this time, the pressure sensor 10 reads the no-load state of the mixing tank body 7.

[0025] Next, the operator pours the required concrete mortar ingredients into the mixing tank body 7. Following the controller's prompts, the operator pours the raw materials into the mixing tank body 7 in sequence. The pressure sensor 10 receives increased pressure until it reaches the set threshold. At this point, the controller alerts the operator via an indicator light. Then, the next type of raw material is poured into the mixing tank body 7 until all raw materials are poured into the mixing tank body 7.

[0026] After the raw material filling is completed, the two lifting hydraulic actuators 14 extend, pushing the two mixing tank limiting sliders 6 upward within the limiting slide 3. The two mixing tank limiting sliders 6 drive the mixing tank body 7 to the high position. Then, the drive ends of the two high-position limiting hydraulic actuators 4 extend, causing the high-position limiting baffle 5 to slide into the slot of the limiting slide 3. Next, the two lifting hydraulic actuators 14 retract, and the two mixing tank limiting sliders 6 drive the mixing tank body 7 downward until the two mixing tank limiting sliders 6 are locked on the upper wall of the high-position limiting baffle 5. Then, the stirring motor 9 starts to rotate, and the drive end of the stirring motor 9 drives the stirring screw 8 to rotate, stirring the raw material inside the mixing tank body 7 until the raw material is evenly mixed.

[0027] After the raw material mixing is completed, the raw material needs to be discharged. First, the electrically controlled valve 13 is opened, and the raw material enters the packaging container through the discharge pipe 12 and the discharge hose 15. Then, the mixing motor 9 reverses, driving the mixing screw plate 8 to rotate, so that the mixed raw material inside the mixing tank body 7 is pressurized and discharged.

[0028] Example: Mechanical structure components: The batching base plate 1, serving as the fundamental support component of the device, is made of high-strength steel and measures 2000mm × 1500mm × 50mm. Its upper surface is treated with rust prevention. The lower wall of the batching base plate 1 has four vibration-damping feet, each made of rubber, 100mm in diameter and 50mm high, used for vibration reduction and stable support. A clearance groove, 500mm × 400mm in size, is provided in the central area of ​​the batching base plate 1 to accommodate the discharge assembly. Two limiting slide assemblies are symmetrically fixed to the upper wall of the batching base plate 1, located on the left and right sides respectively, with a spacing of 1000mm. Each limiting slide assembly includes a limiting elevation platform 2 and a limiting slide 3. The limiting elevation platform 2 is a rectangular steel structure, measuring 300mm × 200mm × 100mm, and is bolted to the batching base plate 1. The limiting slide 3 is a U-shaped guide rail structure, 1500mm long and 200mm high, fixed to the upper wall of the limiting elevation platform 2. The limiting slide 3 has a groove inside, which is 50mm wide and 100mm deep, to guide the lifting and lowering movement of the mixing component.

[0029] Two high-position limiting components are fixed to the outer wall of the limiting slide 3. Each high-position limiting component includes a high-position limiting hydraulic actuator 4 and a high-position limiting baffle 5. The high-position limiting hydraulic actuator 4 is mounted via a bracket welded from angle steel, measuring 150mm × 100mm. The high-position limiting hydraulic actuator 4 is a single-acting hydraulic cylinder with a stroke of 200mm, driven by an external hydraulic power source. The high-position limiting baffle 5 is a rectangular steel plate, measuring 150mm × 50mm × 10mm, and is movably mounted in a slot in the limiting slide 3. The slot is 52mm wide and has a clearance fit with the high-position limiting baffle 5, allowing for smooth sliding. The drive end of the high-position limiting hydraulic actuator 4 is connected to the high-position limiting baffle 5 via a pin, realizing the extension and retraction control of the baffle.

[0030] The mixing assembly is movably mounted inside two limiting slide assemblies. It includes two mixing tank limiting sliders 6, a mixing tank body 7, a mixing screw plate 8, and a mixing motor 9. The mixing tank limiting sliders 6 are rectangular sliders, measuring 100mm × 50mm × 50mm, made of wear-resistant nylon material, and are movably embedded in the grooves of the limiting slide 3. The mixing tank body 7 is a cylindrical structure, 800mm in diameter, 1000mm in height, and 10mm in wall thickness, made of stainless steel, with internal reinforcing ribs. The mixing tank body 7 is fixed between the two mixing tank limiting sliders 6 by welding. A discharge hole with a diameter of 100mm is opened at the center of the lower wall surface of the mixing tank body 7. The mixing screw plate 8 is a spiral blade structure, 800mm in length and 100mm in diameter, and is movably mounted on the internal bearing seat of the mixing tank body 7 via bearings. The mixing motor 9 is a three-phase asynchronous motor, fixed to the lower wall surface of the mixing tank body 7 by a bracket. The drive end of the mixing motor 9 is connected to the mixing screw plate 8 via a coupling to achieve forward and reverse rotation control.

[0031] The weighing assembly is positioned between the batching and mixing assembly and the batching base plate 1. It includes a pressure sensor 10 and a tank support platform 11. The pressure sensor 10 is a strain gauge sensor with a range of 0-10 tons, fixed at the center of the upper wall of the batching base plate 1. The tank support platform 11 is a circular platform with a diameter of 300 mm and a height of 50 mm, made of steel, and fixed to the lower wall of the mixing tank body 7. When the mixing tank body 7 is in a low position, the tank support platform 11 contacts the pressure sensor 10 for weighing.

[0032] The discharge assembly is located on the lower wall of the mixing tank body 7. It includes a discharge pipe 12, an electrically controlled valve 13, and a discharge hose 15. The discharge pipe 12 is a stainless steel pipe with a diameter of 100 mm and a length of 500 mm, with one end welded to the discharge port of the mixing tank body 7. The electrically controlled valve 13 is an electric ball valve with a diameter of 100 mm, installed in the middle of the discharge pipe 12, and controlled by 24V DC. The discharge hose 15 is a rubber hose with a diameter of 100 mm and a length of 1000 mm, connected to the tail end of the discharge pipe 12 for guiding the discharge.

[0033] In addition, the upper walls of the two limiting lifting platforms 2 are respectively equipped with lifting hydraulic devices 14. The lifting hydraulic device 14 is a double-acting hydraulic cylinder with an anti-slip pad made of polyurethane material at the drive end, with a diameter of 50mm, used to push the limiting slider 6 of the mixing tank.

[0034] Electrical structure section: The electrical control system is the core of this device, responsible for coordinating the actions of various actuators to achieve automated operation. The system includes a main controller, sensors, actuators, and a power supply module. The main controller is a Siemens S7-1200 PLC, equipped with digital and analog modules. The sensors include a pressure sensor 10 and a position sensor. The actuators include a high-position limiting hydraulic actuator 4, a lifting hydraulic actuator 14, a stirring motor 9, and an electrically controlled valve 13. The power supply module provides 24V DC and 220V AC power, and an external AC power supply is connected through a junction box.

[0035] Control logic and workflow of the electrical structure: ① Initial State: After the device is powered on, the PLC performs a self-test. All hydraulic actuators are in the retracted state: the high-position limiting hydraulic actuator 4 retracts, and the high-position limiting baffle 5 is in the yield position, i.e., retracted into the slot of the limiting slide 3; the lifting hydraulic actuator 14 retracts, and the mixing tank limiting slider 6 is in the low position of the limiting slide 3, so that the mixing tank body 7 is in the low position. At this time, the tank support platform 11 contacts the pressure sensor 10, the pressure sensor 10 reads the no-load weight, sets it to zero, the PLC records the value and displays it on the HMI, the electrically controlled valve 13 closes, and the stirring motor 9 stops.

[0036] ② Feeding Stage: The operator sets the batching formula via HMI, such as weight thresholds for cement, sand, and water. The PLC sequentially prompts for feeding: First, an indicator light illuminates, indicating the addition of the first raw material, such as cement. The operator pours the material into the mixing tank body 7. The pressure sensor 10 monitors the weight in real time, and the signal is transmitted to the PLC's analog input module. The PLC compares the current weight with the set threshold. When the weight reaches the threshold, the PLC stops the indicator light and activates a buzzer to remind the operator to stop feeding. Then, the PLC prompts for the addition of the next raw material, repeating the process until all materials are added. During feeding, the hydraulic actuator 14 is raised and kept contracted to ensure that the weighing accuracy is not affected by vibration.

[0037] ③ Lifting and Locking Stage: After feeding is completed, the operator confirms the formula is correct and starts the lifting program via HMI. The PLC controls two lifting hydraulic actuators 14 to extend, pushing the mixing tank limiting slider 6 upward along the limiting slide 3. When the mixing tank limiting slider 6 reaches the high position, it is detected by the limit switch and installed at the top of the limiting slide 3. The PLC then stops the lifting hydraulic actuators 14. Next, the PLC controls two high-position limiting hydraulic actuators 4 to extend, driving the high-position limiting baffle 5 to slide into the slot of the limiting slide 3 until the baffle is fully extended, confirmed by the position sensor. Then, the PLC controls the lifting hydraulic actuators 14 to retract, causing the mixing tank limiting slider 6 to descend until it is locked on the upper wall of the high-position limiting baffle 5. At this time, the mixing tank body 7 is locked in the high position, disengaged from the pressure sensor 10, to prevent mixing vibration from interfering with weighing.

[0038] ④ Stirring Stage: After locking, the PLC starts the stirring motor 9, which operates in forward rotation mode, driving the stirring screw plate 8 to rotate. The stirring time is set by the PLC timer, usually 10-15 minutes. During this period, the PLC monitors the motor current and alarms if overload occurs. After stirring is complete, the PLC stops the motor.

[0039] ⑤ Discharge stage: The operator starts the discharge through the HMI. The PLC first controls the mixing motor 9 to reverse, so that the mixing screw plate 8 flips to assist in the discharge. At the same time, the PLC opens the electrically controlled valve 13. The raw material is discharged through the discharge pipe 12 and the discharge hose 15 under the action of gravity. After completion, the PLC closes the electrically controlled valve 13 and the motor.

[0040] ⑥ Reset stage: After discharge, the PLC controls the high-position limiting hydraulic device 4 to retract and the high-position limiting baffle 5 to retract. Then, it controls the lifting hydraulic device 14 to extend and raise the mixing tank body 7 to the high position. Then, it retracts the lifting hydraulic device 14 to lower the tank body to the low position, re-contacts the pressure sensor 10, performs zero-point calibration, and prepares for the next cycle.
