Description

Technical Field

[0001] This utility model relates to the field of mortar feeding technology, and specifically discloses a premixed mortar feeding device. Background Technology

[0002] Premixed mortar is a type of mortar product that is pre-mixed in a factory according to a specific ratio and is widely used in building construction. Compared with traditional on-site mixed mortar, premixed mortar has higher quality stability, construction efficiency, and environmental performance. Specifically, it is a mortar product made by mixing raw materials such as cement, sand, mineral admixtures, and additives in a certain proportion in a professional production plant and undergoing strict quality control.

[0003] A premixed mortar feeding device is a mechanical device used to transport premixed mortar from storage equipment to the construction site. For example, the utility model patent with authorization announcement number CN221314686U discloses a premixed mortar mixing and feeding device, including a support leg, an mounting frame fixedly connected to the upper surface of the support leg, a connecting block fixedly connected to the upper surface of the mounting frame, a crossbar fixedly connected to the upper surface of the connecting block, a blade fixedly connected to the lower surface of the crossbar, a first motor fixedly connected to the left surface of the support leg, a first rotating shaft fixedly connected to the output end of the first motor, a turning device including a vertical plate, a second motor, a second rotating shaft, a second roller, and a mesh conveyor belt, and a mixing device including a discharge port, a turntable, a mixing bucket, a third motor, a third rotating shaft, mixing blades, and a discharge pipe. The turning device turns the raw material bags during transportation, pouring the raw materials inside into the lower part for mixing, while simultaneously discharging waste bags. It allows for uninterrupted feeding, greatly improving work efficiency and making operation extremely convenient.

[0004] Currently, after premixed mortar is mixed, it is generally stored at a fixed location. Then, when needed, the material is taken from the storage area and transported to the mortar processing equipment in the construction area. However, if the transport point is far away, building a transport structure will take up a lot of space. If manual cart transport is used, the efficiency is too low. Therefore, it is necessary to design a mobile mortar storage structure that can be flexibly moved in the construction area. At the same time, it should also have the ability to feed stable mortar processing equipment, so as to ensure the convenience of use and operation in the mortar feeding process. Utility Model Content

[0009] Furthermore, a motor is installed above the hopper, and a drive shaft is installed inside the motor. A shaft is fixedly installed at the end of the shaft via a coupling. Several scrapers are distributed on the surface of the shaft. The side of the scraper away from the shaft slides and is in close contact with the inner wall of the hopper. A spiral blade is wound around the lower end of the shaft, and the outer spiral surface of the spiral blade slides and is in close contact with the inner wall of the discharge port of the hopper.

[0010] Furthermore, the feeding mechanism includes a feeding pipe located above the base and spanning both the wide and narrow opening regions. A support platform is provided on one side of the upper part of the base, with one side of the support platform being an inclined surface. The inclined lower end of the feeding pipe is located on the inclined surface of the support platform, and a sealing plate is provided at the end of the feeding pipe away from the support platform.

[0011] Furthermore, a sealed bearing is installed through the center of the sealing plate, and a shaft is installed through the interior of the sealed bearing. The surface of the shaft is interference-fitted with the inner ring wall of the sealed bearing. A spiral blade is fixedly wound on the surface of the shaft, and the outer spiral blade is rotatably attached to the inner wall of the feeding pipe. A motor is installed outside the shaft, and a rotating shaft is installed inside the motor for driving. The end of the rotating shaft is fixedly connected to the end face of the shaft via a coupling. A discharge port is installed through the lower end of the feeding pipe near the motor. A feed funnel is installed through the upper end of the feeding pipe near the support platform. The feed funnel is located directly below the transition interface. A bearing seat is fixedly installed on the inclined surface of the support platform, and the end of the shaft away from the motor is rotatably installed with the bearing seat.

[0012] Furthermore, the traction connection assembly includes a traction platform, which is located on the base away from the second motor. A rod seat is vertically distributed on the outward side of the traction platform, and a pull rod is inserted into the rod seat. A traction sleeve is provided at the other end of the pull rod.

[0013] Furthermore, the moving component includes a positioning bearing, a connecting shaft is provided through the interior of the positioning bearing, the surface of the connecting shaft is interference-fitted with the inner ring wall of the positioning bearing, and a wheel is installed at the lower end of the connecting shaft.

[0014] Furthermore, the control component includes a console, the housing of which is embedded with a display screen and a control panel. A processor is also embedded inside the housing of the console. Valves, pressure sensors, motor one, and motor two are connected to the processor via power lines.

[0015] The working principle and beneficial effects of this solution are as follows: 1. This solution achieves automated control through control components. The processor included can receive data from pressure sensors in real time to monitor the mortar feeding. Based on this data, the processor precisely controls the operation of motor one and motor two to ensure accurate mortar feeding. The display screen can display the feeding amount in real time, allowing operators to intuitively understand the operating status of the equipment and avoid errors and inconveniences of manual monitoring. In addition, the control panel allows operators to perform various operations, such as starting, stopping, and adjusting motor speed. These operation commands are sent to the processor, which controls the operation of the motors according to the commands. The entire process achieves automated control, improves work efficiency and accuracy, and reduces labor costs and the possibility of operational errors.

[0016] 2. As described in point 1, the motor installed inside the silo, through the shaft and the spiral blade, achieves efficient mixing and stable discharge of the mortar. When the motor rotates forward, the spiral blade feeds the material upward, preventing powdery materials from overflowing from the discharge port of the silo, while also mixing the material. The shaft drives the scraper to rotate, which not only assists in mixing but also cleans the inner wall of the silo to prevent material adhesion. When discharge is required, the motor reverses, and the spiral blade discharges the material downward. With the opening of the valve, a slow, continuous, and stable discharge is achieved. This design not only improves mixing efficiency but also ensures the stability and accuracy of the discharge, avoiding excessive or insufficient discharge that could lead to large errors, thereby ensuring the quality of the mortar and the construction effect.

[0017] 3. As described in section 2, flexible movement and convenient transfer are achieved through the mobile component and the traction connection component. The mobile component, including wheels and positioning bearings, allows the entire device to be easily moved on the construction site. The omnidirectional adjustment function of the wheels further improves the flexibility of movement. The traction connection component, including the traction platform, pole seat, tie rod, and traction sleeve, enables slow movement by using a construction vehicle and traction ropes when transferring the device on the construction site. This design not only improves the portability of the device but also makes the transfer between different construction sites more convenient and efficient. Especially on large construction sites, this ability to move flexibly and transfer conveniently greatly improves work efficiency and reduces the construction restrictions caused by the equipment being stationary.

[0026] The following detailed description illustrates the specific implementation method:

[0027] Example

[0028] like Figures 1 to 6 As shown, a premixed mortar feeding device is disclosed, including a material storage and mixing mechanism 1, a feeding mechanism 2 is arranged below the material storage and mixing mechanism 1, the material storage and mixing mechanism 1 includes a base 10, the feeding mechanism 2 is arranged on the base 10, a traction connecting component 3 is arranged on one side of the base 10, a moving component 4 is arranged below the base 10, and a control component 5 is arranged on one side above the base 10.

[0029] The base 10 includes a wide side area and a narrow side area. A column 11 is positioned above the wide side area, and the lower end of the column 11 is fixed to the surface of the base 10 with screws. The column 11 is distributed along the four corners of the wide side area. A sleeve 12 is slidably fitted onto the surface of the column 11. A pressure sensor 19 is positioned at one end of the column 11 inside the sleeve 12, and is fixed to the end face of the column 11 with screws. Limiting blocks 15 are also provided on the surface of the column 11, with one end fixed to the surface of the column 11 with screws. The limiting blocks 15 are symmetrically distributed along the surface of the column 11. Limiting grooves 16 are formed on the inner wall of the sleeve 12, and the inner wall of the limiting groove 16 slides tightly against the surface of the limiting blocks 15. The sleeves distributed along the four corners... The upper end of the sleeve 12 is provided with the same top plate 13. The top plate 13 and the end of any sleeve 12 are fixed by screws. The center of the top plate 13 is provided with a hopper 14. The connection between the hopper 14 and the top plate 13 is fixed by welding. The hopper 14 has a conical structure and its lower end is the discharge port. The hopper 14 can store premixed mortar. The top plate 13 plays an auxiliary connecting and bearing role. The pressure sensor 19 can weigh the mortar stored in the hopper 14 and detect the mortar discharge volume during continuous discharge. The sleeve 12 slides on the surface of the column 11 and can cooperate with the top plate 13 to settle and move. The limiting block 15 slides inside the limiting groove 16 to prevent the sleeve 12 from slipping off the column 11.

[0030] A transition interface 17 is provided below the silo 14. The transition interface 17 and the discharge interface of the silo 14 are flanged together. A valve 18 is provided on the surface of the transition interface 17. The valve core of the valve 18 is embedded inside the transition interface 17. When it is necessary to mix the material, the valve 18 can be closed to prevent the liquid agent of the material from leaking out. When it is necessary to release the material, the valve 18 can be opened to ensure that the premixed mortar is discharged normally.

[0031] A motor 1001 is installed above the silo 14. The outer wall of the motor 1001 is fixedly mounted to the surface of the top plate 13 via a bracket. Inside the motor 1001 is a drive shaft. A shaft 1002 is fixedly mounted to the end of the shaft 1 via a coupling. Several scrapers 1003 are distributed on the surface of the shaft 1002. One end of each scraper 1003 is fixed to the surface of the shaft 1002 with screws. The scrapers 1003 are evenly distributed along the surface of the shaft 1002. The side of each scraper 1003 away from the shaft 1002 slides against the inner wall of the silo 14. A spiral blade 1004 is wound around the lower end of the shaft 1002. The outer spiral surface of the spiral blade 1004 slides against the inner wall of the discharge port of the silo 14. When premixed mortar raw materials are added to the silo 14, the motor is turned on to ensure stable mixing. The power supply for motor 1001 is externally connected to a forward / reverse switch via wires. The forward / reverse switch allows motor 1001 to rotate in both directions. When motor 1001 rotates forward, its shaft 1002 drives the spiral blade 1004 to spiral upward, thus preventing powder material from overflowing from the discharge port of hopper 14. It also has a stirring effect on the material. Furthermore, shaft 1002 can drive scraper 1003 to rotate, which can assist in stirring and also scrape the inner wall of hopper 14 to prevent adhesion. When discharge is required, motor 1001 reverses, causing shaft 1002 to drive spiral blade 1004 to spiral downward for discharge. Simultaneously, valve 18 is opened to achieve slow, continuous, and stable discharge. During discharge, pressure sensor 19 can also continuously detect the weight of the discharged material to avoid excessive or insufficient discharge, which could lead to large errors.

[0032] The feeding mechanism 2 includes a feeding pipe 20, which is located above the base 10 and spans both the wide and narrow opening areas. The middle part of the feeding pipe 20 is fixedly installed to the narrow opening area of ​​the base 10 via a bracket. A support platform 21 is provided on one side of the upper part of the base 10. The lower end of the support platform 21 is fixedly installed to the connection point of the base 10 via screws. One side of the support platform 21 is an inclined surface. The inclined lower end of the feeding pipe 20 is set on the inclined surface of the support platform 21. One end of the feeding pipe 20 is welded and fixed to the surface of the support platform 21. The support platform 21 can close one end of the feeding pipe 20 and make it form an inclined structure with respect to the horizontal plane. A sealing plate 22 is provided at the end of the feeding pipe 20 away from the support platform 21. The sealing plate 22 is fixed to the end face of the feeding pipe 20 by welding.

[0033] A sealing bearing 23 is installed through the center of the sealing plate 22. The sealing bearing 23 is fixed to the sealing plate 22 by welding. A shaft 24 is installed through the interior of the sealing bearing 23. The surface of the shaft 24 is interference-fitted with the inner ring wall of the sealing bearing 23. A spiral blade 26 is fixedly wound on the surface of the shaft 24. The outer spiral blade of the spiral blade 26 is rotated and tightly attached to the inner wall of the feeding pipe 20. A motor 27 is installed outside the shaft 24. The outer wall of the motor 27 is fixedly installed to the surface of the sealing plate 22 by a bracket. A rotating shaft 2 for driving is installed inside the motor 27. The end of the rotating shaft 2 is fixedly connected to the end face of the shaft 24 by a coupling. A discharge port 28 is installed through the lower end of the feeding pipe 20 near the motor 27. The connection between the discharge port 28 and the feeding pipe 20 is fixed by welding. A feed funnel 29 is installed through the upper end of the feeding pipe 20 near the support platform 21. The connection between the funnel 29 and the feeding pipe 20 is fixed by welding. The feeding funnel 29 is located directly below the transition interface 17, and the upper end of the feeding funnel 29 has a wide opening diameter twice that of the transition interface 17. This ensures that the feeding funnel 29 can stably receive the material released from the transition interface 17 without spilling. When feeding is required, the material is released from the transition interface 17 and enters the feeding funnel 29. At this time, the power supply of the second motor 27 is turned on, and the rotating shaft of the second motor 27 drives the second shaft 24 to rotate, thereby realizing the rotation of the second spiral blade 26 and realizing the spiral upward conveying of the material. After continuous conveying in the feeding pipe 20, the material can finally be discharged downward through the discharge interface 28 and enter the mechanical equipment for further processing of mortar. The inclined surface of the support platform 21 is fixedly installed with a bearing seat 25. The end of the second shaft 24 away from the second motor 27 is rotatably installed with the bearing seat 25. The bearing seat 25 can ensure the stable transmission of the second shaft 24.

[0034] The traction connection assembly 3 includes a traction platform 30, which is located on the base 10 away from the motor 27. The lower end of the traction platform 30 is fixed to the surface of the base 10 by screws. A pole seat 31 is vertically distributed on the outward side of the traction platform 30.

The connection between the traction sleeve 33 and the pull rod 32 is fixed by welding. The upper and lower traction sleeves 33 can be used simultaneously or independently. When transferring on the construction site, they can be slowly moved by the construction vehicle and the traction rope, thus achieving flexible transfer.

[0035] The moving component 4 includes a positioning bearing 40, and a connecting shaft 41 is provided through the interior of the positioning bearing 40. The surface of the connecting shaft 41 is interference-fitted with the inner ring wall of the positioning bearing 40. A wheel 42 is installed at the lower end of the connecting shaft 41. The wheel frame of the wheel 42 is fixed to the lower end of the connecting shaft 41 by screws. The wheels 42 are evenly distributed at the lower ends of the wide and narrow opening areas of the base 10. The rolling of the wheels 42 facilitates the movement of the entire structure. The connecting shaft 41 can rotate based on the positioning bearing 40, thereby facilitating the omnidirectional adjustment of the wheels 42 during movement.

[0036] The control component 5 includes a console 50, whose housing is embedded with a display screen 51 and a control panel 52. A processor is also embedded inside the console 50 housing. Valves 18, pressure sensors 19, motor 1001, and motor 27 are connected to the processor via power lines. The display screen 51 and control panel 52 are connected to the processor via data lines. Valves 18 are solenoid valves. During normal material feeding, pressure sensors 19 monitor the mortar feeding in real time and transmit the data to the processor. The processor controls the operation of motors 1001 and 27 based on this data to ensure accurate mortar feeding. Simultaneously, the display screen 51 shows the current feeding amount, allowing operators to intuitively understand the equipment's operating status. Operators can perform various operations via the control panel 52, such as starting, stopping, and adjusting motor speeds. These operation commands are sent to the processor, which controls the motor operation accordingly. The entire process achieves automated control, improving work efficiency and accuracy.

[0037] In practice

[0038] The core function of the material storage and mixing mechanism 1 in this scheme is to store and mix premixed mortar. The silo 14 serves as the main container, and its conical structure facilitates the concentration of materials to the discharge port. When the raw materials are put into the silo 14, the motor 1001 starts and drives the shaft 1002 to rotate, which in turn drives the scraper 1003 and the spiral blade 1004 to move. The scraper 1003 rotates close to the inner wall of the silo 14 to prevent material from adhering. When the spiral blade 1004 rotates forward, it pushes the material upward to prevent powder from overflowing. When it rotates in reverse, it conveys the material downward to achieve discharge. The pressure sensor 19 monitors the weight of the material in the silo 14 in real time and controls the discharge amount in conjunction with the opening and closing of the valve 18. The sleeve 12 slides along the column 11, and the stability is ensured by the cooperation of the limit block 15 and the limit groove 16. The top plate 13 bears the overall weight of the silo 14. This process realizes the storage, mixing and accurate metering of materials.

[0039] The feeding mechanism 2 is responsible for conveying the mortar released by the storage and mixing mechanism 1 to the designated position. The material in the transition interface 17 enters the feeding pipe 20 through the feeding funnel 29. The motor 27 drives the shaft 24 to rotate, which drives the spiral blade 26 to rotate, pushing the material along the feeding pipe 20 to the discharge interface 28. The inclined design of the support platform 21 ensures the inclination angle of the feeding pipe 20, which facilitates the flow of materials. The bearing seat 25 and the sealed bearing 23 ensure the stable operation of the shaft 24. The discharge interface 28 is connected to the downstream equipment to realize continuous feeding. The wide opening design of the feeding funnel 29 prevents the material from spilling. The sealing plate 22 and the bracket fix the position of the feeding pipe 20. This mechanism efficiently completes the horizontal or inclined transfer of materials through the spiral conveying principle, which is suitable for the needs of different construction scenarios.

[0040] The traction connection assembly 3 and the moving assembly 4 work together to achieve flexible transfer of the device. The traction platform 30 is connected to external traction equipment (such as construction vehicles) through the tie rod 32 and the traction sleeve 33, dragging the entire device to move. The wheels 42 are connected to the positioning bearing 40 through the universal rotation of the connecting shaft 41, which can adapt to traction forces in different directions. The wheels 42 are distributed in the wide and narrow side areas of the base 10 to ensure load balance. The pole seat 31 fixes the position of the tie rod 32 and provides multiple traction point selection.

[0041] The control component 5 integrates the automated management of valve 18, pressure sensor 19, motor 1001, and motor 27. The processor receives real-time weight data from pressure sensor 19 and controls the forward and reverse rotation and speed of motor 1001 through algorithms. It also adjusts the feeding direction and speed of spiral vane 1004. The solenoid valve characteristics of valve 18 are precisely switched by the processor to ensure that the output meets the set value. The start, stop, and conveying speed of motor 27 are adjusted synchronously by the processor through input commands on control panel 52. The display screen 51 dynamically displays parameters such as weight and motor status, which facilitates manual intervention. This automated system reduces human error, improves the accuracy of mortar mixing and conveying, and reduces the complexity of operation.

[0042] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
