Description

Technical Field

[0001] The invention relates to the technical field of building concrete feeding, and in particular to a concrete aerial silo and a full-automatic intelligent feeding control system. Background Art

[0002] Concrete aerial silos are equipment used to store concrete raw materials. They are usually located above concrete mixing plants. They can transport raw materials to the mixing plant for mixing through conveyor belts or other conveying equipment. The design of this silo can effectively utilize space and improve production efficiency.

[0003] The patent with announcement number CN207841746U discloses a new type of aerial silo for concrete aggregates, including a silo and a conveying device for conveying aggregates to the top of the silo. The overall structure of the aggregate storage silo is all above the ground, and the aggregates are loaded using a cloth conveying system. In the actual use of the new type of aerial silo for concrete aggregates of the utility model, the aggregates are transported upward to the first group of conveying devices connected to the discharge end of the main conveying device through the main conveying device, and then the aggregates are transported to the first silo monomers arranged around the first rotating shaft through the first rotating conveying device of the first group of conveying devices connected to the discharge end of the main conveying device. Specifically, the function of conveying aggregates to each silo is realized by the first rotating conveying device relying on the rotation of the first rotating shaft, thereby achieving the effect of efficient transportation to multiple silos and flexible and convenient operation. Compared with the prior art, the above scheme is more efficient and flexible in transporting aggregates and has strong practicality.

[0004] The above technical solution does not have a quantitative feeding operation in the process of feeding the raw materials into the mixing drum, which will cause large fluctuations in the supply of aggregates. If there are too many aggregates, the strength of the concrete will be too high. At the same time, the relative proportion of other ingredients such as cement will be reduced, affecting the working performance of the concrete, such as poor fluidity, which is not conducive to construction operations. If there are too few aggregates, the strength of the concrete will not meet the requirements, affecting the safety of the building structure. At the same time, the height position of the silo cannot be changed during the process of filling the raw materials into the silo, making it difficult to reduce the transportation distance and reduce the energy loss during transportation.

[0009] As a preferred solution of the present invention, a ball valve is installed at one end of the outer surface of the mixing drum so that the ball valve can discharge the mixed concrete raw materials.

[0010] As a preferred embodiment of the present invention, both sets of stirring rods pass through the mixing drum through sealed bearings, and a first gear is fixedly installed at one end of the stirring rod passing through the mixing drum, a second gear is rotatably installed between the two sets of first gears and meshes with each other, the second gear is fixedly installed at one end of the output shaft of the first motor, and the first motor is fixedly installed on the upper surface of the bottom plate, so that the second gear can transmit the two sets of first gears to drive the stirring rods to rotate relative to each other in the mixing drum.

[0011] As a preferred embodiment of the present invention, the lifting mechanism includes two groups of first support wheels and two groups of second support wheels. The two groups of first support wheels are rotatably installed on the lower halves of both sides of the silo, and the two groups of second support wheels are rotatably installed on both ends of the mounting plate. The mounting plate is installed on the upper half of one end of the outer surface of the silo, so that the two groups of second support wheels are also located in the upper halves of both sides of the silo, and the two groups of first support wheels and the second support wheels both roll in the U-shaped groove opened on the inner side of the support plate.

[0012] As a further solution of the present invention, a connecting column is fixedly installed in the middle part of the mounting plate, a steel wire rope is fixedly connected inside the connecting column, the other end of the steel wire rope fixedly connected to the outer surface of the connecting column is fixedly connected to the outer surface of the winding drum, the winding drum is fixedly installed on one end of the output shaft of the third motor, the third motor is fixedly installed on one end of the docking plate, and the docking plate is fixedly installed on one end of the top of the support plate.

[0014] The present invention also provides a fully automatic intelligent feeding control system, which is used to control the intelligent feeding of the above-mentioned concrete aerial silo.

[0016] As a further solution of the present invention, the rotating rods at both ends of the rotating drum rotate out from the discharge port and are fixedly connected to the output shaft of the second motor. The second motor is fixedly installed at one end of the silo. The PLC controller is electrically connected to the first motor, the third motor and the second motor respectively, and the PLC controller is used to control the automatic operation of the first motor, the third motor and the second motor.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the process of feeding the silo into the mixing drum, the silo can be driven by the lifting mechanism to slide down in the U-shaped groove provided on the inner side of the support plate, so as to lower the height of the silo, so as to facilitate the filling of the concrete raw materials into the silo. After the concrete raw materials are filled into the silo, the lifting mechanism is started again to drive the silo back to the original height. In the process of the silo being lifted, the guide plate is driven to touch the lower surface of the protective cover, so that the guide plate is covered by the protective cover to avoid splashing in the process of guiding the concrete raw materials. Subsequently, when pouring the concrete raw materials into the mixing drum, the quantitative feeding mechanism can be started to rotate in the discharge port, and when the quantitative feeding mechanism rotates in the discharge port, the quantitative feeding mechanism pours the concrete raw materials in the silo into the mixing drum in a quantitative manner. In the drum, precise quantitative feeding ensures the accuracy of the proportion of each component of concrete, ensures the stability of the quality of concrete, and meets the requirements of different projects for concrete strength and workability. Then the first motor can be started to drive the second gear to mesh and transmit the two sets of first gears, driving the stirring rod to rotate relatively in the mixing drum to stir the concrete. The relative rotation method makes the concrete more comprehensive and sufficient in the mixing drum, breaks the agglomeration structure inside the concrete, makes the cement and aggregate components better mixed, improves the uniformity of the concrete, and thus improves the quality of the concrete. After mixing, the ball valve can be opened to discharge the stirred concrete raw materials for use, and the opening and closing of the ball valve can conveniently control the start and stop of discharging, making the discharging process more controllable.

[0019] 2. When filling the raw materials into the silo, start the third motor to drive the winding reel to release the wire rope. The wire rope is fixed to one end of the silo through the mounting plate, so that the silo can make the first support wheel and the second support wheel roll down a certain distance in the U-shaped groove opened on the inner side of the support plate through the loose length of the wire rope, thereby lowering the height position of the silo, so as to provide great convenience for filling the concrete raw materials into the silo, so that the parameters such as the drop of raw material transportation can be adjusted according to the actual situation to improve the transportation efficiency, and adjusting the height of the silo to a suitable position can reduce the transportation distance The third motor can be started again after filling to drive the winding drum to wind up the wire rope, so that the wire rope pulls the silo to roll upward through the first support wheel and the second support wheel in the U-shaped groove on the inner side of the support plate, so that the winding drum can achieve the rise and fall of the silo by winding and releasing the wire rope, and support the silo at an angle so that the silo can remain vertical during the rise and fall process, which helps to prevent the raw materials in the silo from overflowing or unevenly piling up, and ensure the quality of the raw materials and the smooth progress of production.

[0020] 3. When quantitatively supplying concrete raw materials into the mixing drum, start the second motor to drive the drum to rotate in the discharge port, so that the drum drives a group of filling ports opened on the outer surface to face the silo, and the concrete raw materials in the silo are automatically filled into the filling port. When the drum drives the filling port filled with concrete raw materials to rotate, the discharge port can scrape off the excess raw materials in the filling port to ensure that a certain amount of concrete is stored in the filling port. After the drum drives the filling port to rotate to the lower end of the discharge port, the filling port can pour the stored concrete raw materials into the guide plate, so that the concrete raw materials flow into the mixing drum through the guide plate, and the filling port is on the outer surface of the drum. There are three groups, so that every time the drum is driven to rotate one circle, the filling port can pour the concrete raw materials in the silo into the mixing drum in three quantitative forms, so as to realize the operation of automatic quantitative feeding, and the total amount of concrete supplied can be regulated according to the number of rotations of the second motor, thereby ensuring the accuracy of the proportion of each component in the concrete production process, so that in the production of high-strength concrete, accurate proportioning can be achieved to ensure that the concrete reaches the designed strength standard, avoid quality problems caused by inaccurate raw material quantities, ensure the stability of concrete quality, and help improve the consistency of project quality and reduce safety hazards of building structures caused by fluctuations in concrete quality.

[0033] See also Figure 1-Figure 4As shown, an embodiment of the present invention is a concrete aerial silo, comprising a bottom plate 1, a mixing drum 101 is fixedly installed on the upper surface of the bottom plate 1, two sets of mixing rods 111 are rotatably installed in the mixing drum 101, a support plate 102 is fixedly installed on the other end of the upper surface of the bottom plate 1, a lifting mechanism 2 is slidably installed in the support plate 102, a silo 103 is fixedly installed on one end of the lifting mechanism 2, and a guide plate 110 is connected and installed on the lower surface of the silo 103, so that the silo 103 can be lifted and lifted by the lifting mechanism 2, and can slide and lift in the support plate 102, and can make the silo 103 The guide plate 110 is driven to touch the lower surface of the protective cover 105. The protective cover 105 is fixedly installed at one end of the support plate 102 and covers one end of the upper surface of the mixing drum 101, so that the guide plate 110 can cover the protective cover 105 to avoid splashing during the process of guiding the concrete raw materials. A discharge port 112 is opened between the silo 103 and the guide plate 110. A quantitative feeding mechanism 3 is rotatably installed in the discharge port 112, so that the quantitative feeding mechanism 3 can quantitatively feed the concrete raw materials in the silo 103 into the mixing drum 101 in batches.

[0034] A closing cover 106 is slidably mounted on the outer surface of the protective cover 105 , and the closing cover 106 can be slidably mounted on the outer surface of the protective cover 105 to cover the other end of the mixing drum 101 .

[0035] One end of the outer surface of the mixing drum 101 is connected to a ball valve 107 so that the ball valve 107 can discharge the mixed concrete raw materials.

[0036] Both groups of stirring rods 111 pass through the mixing drum 101 through sealed bearings, and a first gear 109 is fixedly installed at one end of the stirring rod 111 passing through the mixing drum 101. A second gear 113 is rotatably installed between the two groups of first gears 109 and meshes with each other. The second gear 113 is fixedly installed at one end of the output shaft of the first motor 108, and the first motor 108 is fixedly installed on the upper surface of the base plate 1, so that the second gear 113 can transmit the two groups of first gears 109 to drive the stirring rods 111 to rotate relatively in the mixing drum 101.

[0037] In the process of loading the silo 103 into the mixing drum 101, the silo 103 can be first driven by the lifting mechanism 2 to slide down in the U-shaped groove opened on the inner side of the support plate 102 to lower the height position of the silo 103, which provides great convenience for the staff to fill the concrete raw materials into the silo 103, reduces the labor intensity and safety risks, and improves the efficiency of loading raw materials. Subsequently, the staff can fill the silo 103 with concrete raw materials and start the lifting mechanism 2 again to drive the silo 103 back to its original height position. In the process of the silo 103 being lifted, the guide plate 110 will be driven to touch the lower surface of the protective cover 105, so that the guide plate 110 can be covered by the protective cover 105 to avoid splashing during the process of guiding the concrete raw materials. Subsequently, when pouring the concrete raw materials into the mixing drum 101, the quantitative feeding mechanism 3 can be started to rotate in the discharge port 112, and the quantitative feeding mechanism 3 can feed the concrete raw materials quantitatively every time it rotates one circle in the discharge port 112. The mechanism 3 pours the concrete raw materials in the silo 103 into the mixing drum 101 in three times of quantitative feeding. This precise quantitative feeding method ensures the accuracy of the proportion of each component of the concrete, can ensure the stability of the quality of the concrete, and meet the requirements of different projects for the strength, workability and other properties of the concrete. Then, the first motor 108 can be started to drive the second gear 113 to mesh and transmit the two sets of first gears 109 to drive the stirring rod 111 to rotate relatively in the mixing drum 101 to stir the concrete. This relative rotation method can make the concrete more comprehensively and fully stirred in the mixing drum 101, and can break the agglomeration structure inside the concrete, so that the cement, aggregate and other components are better mixed, and the uniformity of the concrete is improved, thereby improving the quality of the concrete. After the mixing is completed, the stirred concrete raw materials can be discharged for use by opening the ball valve 107, and the opening and closing of the ball valve 107 can conveniently control the start and stop of the discharge, making the discharge process more controllable.

[0038] like Figure 5 As shown, the lifting mechanism 2 includes two groups of first support wheels 203 and two groups of second support wheels 205. The two groups of first support wheels 203 are rotatably installed on the lower halves of both sides of the silo 103, and the two groups of second support wheels 205 are rotatably installed on both ends of the mounting plate 204. The mounting plate 204 is installed on the upper half of one end of the outer surface of the silo 103, so that the two groups of second support wheels 205 are also located in the upper halves of both sides of the silo 103. The two groups of first support wheels 203 and the second support wheels 205 both roll in the U-shaped groove opened on the inner side of the support plate 102.

[0039] A connecting column 206 is fixedly installed in the middle part of the mounting plate 204, a steel wire rope is fixedly connected inside the connecting column 206, the other end of the steel wire rope fixedly connected to the outer surface of the connecting column 206 is fixedly connected to the outer surface of the winding drum 202, the winding drum 202 is fixedly installed on one end of the output shaft of the third motor 201, the third motor 201 is fixedly installed on one end of the docking plate 104, and the docking plate 104 is fixedly installed on one end of the top of the support plate 102.

[0040] In this way, the winding drum 202 can achieve the raising and lowering of the silo 103 by winding and releasing the wire rope, and the silo 103 can roll in the U-shaped groove opened on the inner side of the support plate 102 through the first support wheel 203 and the second support wheel 205, and the silo 103 is supported at an angle so that the silo 103 can maintain a vertical state during the rising and falling process.

[0041] When filling raw materials into the silo 103, the third motor 201 can be started to drive the winding drum 202 to loosen the wire rope, and the other end of the wire rope is fixedly connected to one end of the mounting plate 204, and the mounting plate 204 is fixedly mounted on one end of the silo 103, so that the silo 103 can be rolled down a certain distance in the U-shaped groove provided on the inner side of the support plate 102 through the first support wheel 203 and the second support wheel 205 according to the loosened length of the wire rope, thereby lowering the height position of the silo 103, providing great convenience for the staff to fill the concrete raw materials into the silo 103, so that the staff can adjust the parameters such as the drop of raw material transportation according to the actual situation to improve the transportation efficiency, and adjusting the height of the silo 103 to a suitable position can reduce the transportation distance and reduce the energy consumption during transportation. The third motor 201 can be started again after filling to drive the winding drum 202 to wind up the wire rope, so that the wire rope can pull the bin 103 to roll upward in the U-shaped groove opened on the inner side of the support plate 102 through the first support wheel 203 and the second support wheel 205, so that the winding drum 202 can realize the rising and falling of the bin 103 by winding and releasing the wire rope, and can make the bin 103 roll in the U-shaped groove opened on the inner side of the support plate 102 through the first support wheel 203 and the second support wheel 205, and support the bin 103 at an angle, so that the bin 103 can maintain a vertical state during the rising and falling process, which helps to prevent the raw materials in the bin 103 from overflowing or unevenly stacking, and ensures the quality of the raw materials and the smooth progress of production.

[0042] like Figure 6-Figure 7As shown, the embodiment of the present invention also provides a fully automatic intelligent feeding control system, which is used to control the intelligent feeding of the above-mentioned concrete aerial silo. The fully automatic intelligent feeding control system includes: a rotating drum 302 in the quantitative feeding mechanism 3 and a PLC controller. The rotating drum 302 is rotatably installed in the discharge port 112. Three groups of filling ports 303 are opened on the outer surface of the rotating drum 302. When the rotating drum 302 drives a group of filling ports 303 opened on the outer surface to face the silo 103, the concrete raw materials in the silo 103 can be automatically filled into the filling ports 303.

[0043] When the drum 302 drives the filling port 303 filled with concrete raw materials to rotate, the discharge port 112 can scrape off the excess raw materials in the filling port 303 to ensure that only a certain amount of concrete is stored in the filling port 303, until the drum 302 drives the filling port 303 to rotate to the lower end of the discharge port 112, the filling port 303 can pour the stored concrete raw materials into the guide plate 110, so that the concrete raw materials flow into the mixing drum 101 through the guide plate 110, thereby realizing the operation of automatic quantitative feeding.

[0044] The rotating rods at both ends of the rotating drum 302 rotate out from the discharge port 112 and are fixedly connected to the output shaft of the second motor 301. The second motor 301 is fixedly installed at one end of the silo 103. The PLC controller is electrically connected to the first motor 108, the third motor 201 and the second motor 301 respectively, and the PLC controller is used to control the automatic operation of the first motor 108, the third motor 201 and the second motor 301.

[0045] When the concrete raw material is quantitatively supplied to the mixing drum 101, the second motor 301 can be started to drive the rotating drum 302 to rotate in the discharge port 112, so that the rotating drum 302 can drive a group of filling ports 303 opened on the outer surface to face the silo 103, so that the concrete raw material in the silo 103 can be automatically filled into the filling port 303, and then the rotating drum 302 can drive the filling port 303 filled with concrete raw materials to rotate, so that the discharge port 112 can scrape off the excess raw materials in the filling port 303, and only ensure that a certain amount of concrete is stored in the filling port 303, until the rotating drum 302 drives the filling port 303 to rotate to the lower end of the discharge port 112, so that the filling port 303 can pour the stored concrete raw materials into the guide plate 110, so that the concrete raw materials pass through the guide plate 110. 10 flows into the mixing drum 101, and three groups of filling ports 303 are opened on the outer surface of the rotating drum 302, so that the filling ports 303 can pour the concrete raw materials in the silo 103 into the mixing drum 101 in three quantitative amounts every time the rotating drum 302 is driven to rotate one circle, so as to realize the operation of automatic quantitative feeding, and the total amount of concrete supplied can be regulated according to the number of rotations of the second motor 301, thereby ensuring the accuracy of the proportion of each component in the concrete production process, so that in the production of high-strength concrete, the precise proportion can ensure that the concrete reaches the designed strength standard, avoids quality problems caused by inaccurate raw material quantities, and can ensure the stability of the quality of each batch of concrete, which is conducive to improving the consistency of engineering quality and reducing the potential safety hazards of building structures caused by fluctuations in concrete quality.

[0046] According to the above technical solution, the working steps of the technical solution of the present invention are sorted out: in the process of feeding the material bin 103 into the mixing drum 101, it is necessary to first fill the material bin 103 with raw materials, and when filling the material bin 103 with raw materials, the third motor 201 can be started to drive the winding disk 202 to loosen the wire rope, and the other end of the wire rope is fixedly connected to one end of the mounting plate 204, and the mounting plate 204 is fixedly installed at one end of the material bin 103, so that the material bin 103 can be moved on the support plate 102 through the first support wheel 203 and the second support wheel 205 by the loose length of the wire rope. The silo 103 is lowered by rolling down a certain distance in the U-shaped groove on the inner side, which provides great convenience for the staff to fill the concrete raw materials into the silo 103. After the filling is completed, the third motor 201 can be started again to drive the winding drum 202 to wind the wire rope, so that the wire rope can pull the silo 103 through the first support wheel 203 and the second support wheel 205 to roll upward in the U-shaped groove on the inner side of the support plate 102, so as to increase the height of the silo 103, and stop after driving the silo 103 back to the original height position. When quantitatively supplying concrete raw materials into the mixing drum 101, the second motor 301 can be started to drive the rotating drum 302 to rotate in the discharge port 112, so that the rotating drum 302 can drive a group of filling ports 303 opened on the outer surface to face the silo 103, so that the concrete raw materials in the silo 103 can be automatically filled into the filling ports 303, and then the rotating drum 302 can drive the filling ports 303 filled with concrete raw materials to rotate, so that the discharge port 112 can scrape off the excess raw materials in the filling ports 303, so as to ensure that only a certain amount of concrete is stored in the filling ports 303. Until the drum 302 drives the filling port 303 to rotate at the lower end of the discharge port 112, the filling port 303 can pour the stored concrete raw materials into the guide plate 110, so that the concrete raw materials flow into the mixing drum 101 through the guide plate 110, and the filling port 303 is opened on the outer surface of the drum 302. Three groups of filling ports 303 can be made, so that the filling ports 303 can pour the concrete raw materials in the silo 103 into the mixing drum 101 in three quantitative amounts every time the drum 302 is driven to rotate one circle, and the total amount of concrete supplied can be adjusted according to the number of rotations of the second motor 301.

[0047] In summary, the present invention can quantitatively supply concrete raw materials into the mixing drum 101. The precise quantitative feeding method ensures the accuracy of the proportions of the various components of the concrete, ensures the stability of the concrete quality, and is beneficial to improving the consistency of the project quality. In addition, during the process of filling the raw materials into the silo 103, the position of the silo 103 can be lowered, thereby reducing the transportation distance and reducing the energy loss during the transportation process.

[0048] The above shows and describes the basic principle of the present invention.
