Description

Technical Field

[0001] The present invention relates to the field of construction engineering machinery, and in particular to a concrete mixing device and method for water transport engineering. Background Art

[0002] Water transport engineering is a branch of civil engineering. The work content and application technology are basically the same or interlinked with civil engineering, but the service objects focus on the water transport industry. Water transport engineering includes coastal, offshore or inland river projects such as ports, waterways, breakwaters (sand dikes), revetments (seawalls), ship locks (navigation structures), docks, etc. Water transport engineering refers to port engineering, waterway engineering, navigation engineering, navigation structure engineering, ship repair and construction hydraulic structure engineering, installation engineering and support systems and their auxiliary and ancillary engineering. At present, some concrete mixing facilities with different structures have also appeared.

[0003] After searching, it was found that the utility model with patent number CN201720465701.1 discloses a concrete mixing device, which includes a supporting frame, a lifting platform, a lifting mechanism, a mixing device and a lifting platform. The lifting platform can be installed on the supporting frame so as to move up and down. The lifting mechanism is connected to the lifting platform so as to actuate the lifting mechanism to move the lifting platform up and down on the supporting frame. The mixing device is installed on the lifting platform. The mixing device includes a rotating cylinder, a rotation drive mechanism, a revolution drive mechanism and two stirring paddles eccentrically and rotatably supported on the rotating cylinder. The rotation drive mechanism is respectively connected to the two stirring paddles so that the two stirring paddles rotate on the rotating cylinder and rotate in opposite directions. The revolution drive mechanism is connected to the rotating cylinder.

[0004] The utility model with patent number CN201520550372.1 provides a concrete mixing device and a concrete mixer truck having the same, comprising: a tank body and a mixing device arranged in the tank body, the tank body having a feed port and a discharge port, the tank body comprising a first circular cylinder and a second circular cylinder arranged side by side and connected to each other; the mixing device comprises a first mixing shaft, a second mixing shaft, a first mixing blade arranged on the first mixing shaft and a second mixing blade arranged on the second mixing shaft, the first mixing shaft is rotatably arranged in the first circular cylinder along the length direction of the first circular cylinder, and the second mixing shaft is rotatably arranged in the second circular cylinder along the length direction of the second circular cylinder.

[0005] The invention with patent number CN201510232586.9 discloses a concrete mixer that can improve the shearing effect on the kneaded material and efficiently knead. It includes a mixer body that can accommodate the materials for premixed concrete, a first kneading shaft that is rotatably arranged in the mixer body, and a plurality of stirring paddles. Each stirring paddle is composed of an arm body connected to the first kneading shaft and a first plate body arranged at the tip of the arm body. The stirring paddles are used to stir the materials. Each first plate body is arranged in a spiral shape so that each first plate body surrounds the first kneading shaft. There is a valley portion at the adjacent position of the plurality of first plate bodies. The space near the valley portion irregularly changes as the stirring paddle rotates, and the flow of the materials also moves irregularly corresponding to the change of this space.

[0006] However, through analysis, it is found that the existing concrete mixers can only stir the concrete in one plane and cannot achieve the all-round stirring of the concrete. Therefore, the concrete cannot be fully stirred, which affects the uniformity of the final concrete and reduces the construction quality. Summary of the Invention

[0007] Therefore, to solve the above deficiencies, the present invention provides a concrete mixing device and method for water transportation engineering that can fully stir the concrete in the mixing container and has no dead corners during the mixing process, thereby effectively ensuring the uniformity of the final concrete and ensuring the construction quality.

[0008] The present invention is implemented as follows. A concrete mixing device for water transportation engineering is constructed, including a frame A, with a box body arranged on the side. A connecting piece is U-shaped with an upward opening and is hinged to the frame A on both sides. The bottom of a mixing bin is hinged to the bottom of the connecting piece. A frame C is arranged on the side of the frame A. A motor B is installed on the frame B. A swinging mechanism B is connected to the motor B and the connecting piece. When the motor B works, it drives the swinging mechanism B to operate, causing the connecting piece to swing back and forth, and the mixing bin swings back and forth with the connecting piece. A frame B is arranged at the rear end of the frame A. A motor A is arranged directly above the mixing bin. A stirrer is arranged in the mixing bin and is connected to the rotating shaft of the motor A. The motor A drives the stirrer to rotate. A swinging mechanism A is connected to the top of the motor A and is installed on the top of the frame B. When the motor A works, the swinging mechanism A drives the motor A and the stirrer to swing left and right. A motor C is installed in the box body. When the motor C works, it drives the mixing bin to rotate around the axis of the hinge with the connecting piece. The mixing bin and the stirrer rotate in opposite directions. The swinging mechanisms A and B drive the mixing bin and the stirrer to swing, changing the angle of the rotation axis of the mixing blades relative to the ground, thereby making the mixing more uniform by using gravity and the change in the direction of the mixing shaft, and being able to meet different usage requirements. It can fully stir the concrete in the mixing container and has no dead corners during the mixing process, thereby effectively ensuring the uniformity of the final concrete and ensuring the construction quality.

[0009] Furthermore, a ring rack integrated with the mixing bin is circumferentially arranged on the outer ring of the mixing bin. A bevel gear meshes with the ring rack and is connected to the frame A through a shaft. The shaft penetrates the frame and extends into the box body, where a pulley A is installed. A pulley B is installed at the rotating shaft of the motor C. The pulley A and the pulley B are connected by a belt. The motor C drives the mixing bin to rotate, and the stirrer rotates in the opposite direction to the mixing bin at the same time, improving the concrete mixing efficiency.

[0010] Furthermore, a discharge port is opened at the bottom of the side of the mixing bin. A door panel is arranged at the discharge port. The door panel is hinged to the side of the discharge port. When the door panel is closed, the lower part of the mixing bin is in a closed state. When the door panel is closed, the concrete and water will not leak out, increasing the sealing performance of the mixing bin while ensuring convenient discharging.

[0011] Furthermore, the swing mechanism A includes a worm gear, a worm, a connecting rod A, a connecting rod B and a shaft A. A housing is installed at the top of the motor A. A worm integrated with the rotating shaft of the motor A is arranged in the housing. A worm gear and a gear E are also arranged in the housing and are connected through a shaft A and are hinged to the housing. The worm gear meshes with the worm. A gear F is also arranged in the housing and is hinged to the housing through a shaft B and meshes with the gear E. The end of the shaft B far from the gear F penetrates the housing and is hinged to a connecting rod B. The other end of the connecting rod B is hinged to a connecting rod A. The end of the connecting rod A far from the connecting rod B is hinged to the frame B. A shaft A is arranged on the side of the motor A and is hinged to the frame B. By driving the worm gear and worm transmission through the motor A, the connecting rod A and the connecting rod B rotate, driving the motor A to swing left and right, so as to change the angle of the stirrer relative to the ground, thereby making the mixing more uniform by using the change of the direction of gravity and the stirring shaft.

[0012] Furthermore, the swing mechanism B includes a gear A, a gear B, an eccentric block and a swing rod. The gear B and the gear A are installed on the frame C. The gear B is connected to the motor B. The gear A meshes with the gear B. The eccentric block is connected to the eccentric part of the gear A. One end of the swing rod is hinged to the frame C, and a groove is opened in the middle and is slidably connected to the eccentric block. The end far from the frame C is connected to the mixing bin, driving the mixing bin to swing back and forth. The motor B drives the gear transmission, driving the eccentric block to rotate, making the swing rod swing back and forth, and then driving the mixing bin to swing. When the concrete is being mixed, the stirrer can mix the concrete in all directions, accelerating the mixing efficiency and improving the mixing effect.

[0013] Furthermore, an installation part is arranged at the connection between the eccentric block and the gear A. The installation part is fixedly installed on the side of the gear A. A screw rod is hinged in the installation part. The screw rod is threadedly connected to the eccentric block. Rotating the screw rod makes the eccentric block slide in the groove in the middle of the swing rod, adjusting the swing amplitude of the swing rod.

[0014] Further, a gear D is provided at the connection between the stirring bin near the swing mechanism B and the frame A. The gear D is hinged to the frame A and fixedly connected to the stirring bin. A gear C is engaged below the gear D, and the gear C is connected to the swing rod.

[0015] Further, a water level sensor is installed in the stirring bin to monitor the water level in the stirring bin in real time.

[0016] Further, an audible and visual alarm and a controller are installed in the box body.

[0017] A concrete mixing method for a water transportation project is realized as follows: The raw materials and water are injected through the upper opening of the stirring bin. The water level sensor monitors the water level in the stirring bin. When the water level exceeds the limit, the audible and visual alarm gives an alarm. The equipment is started, and the controller controls the motor A to drive the stirrer to rotate. At the same time, the top screw drives the worm gear, gear E, and gear F, driving the connecting rod A and connecting rod B to rotate, thereby driving the motor A to swing left and right, changing the angle of the stirrer shaft relative to the ground. At the same time, the motor B drives the gear A and gear B to rotate. The eccentric block rotates with the gear A and slides in the middle groove of the swing rod, enabling the swing rod to swing back and forth. The screw is rotated to adjust the center distance between the eccentric block and the gear A, thereby changing the swing amplitude of the swing rod. At this time, the motor C also drives the stirring bin to rotate simultaneously to mix the concrete. After mixing is completed, the door panel at the bottom of the side of the stirring bin is opened to discharge the concrete.

[0018] The present invention has the following advantages: The present invention provides a concrete mixing device for a water transportation project that can fully mix the concrete in the mixing container and has no mixing dead corners during the mixing process, thereby effectively ensuring the uniformity of the final concrete and ensuring the construction quality.

A stirrer is arranged inside the mixing bin and is connected to the rotating shaft of the motor A. The motor A drives the stirrer to rotate. A swinging mechanism A is connected to the top of the motor A and is installed on the top of the frame B. When the motor A works, the swinging mechanism A drives the motor A and the stirrer to swing left and right. A motor C is installed inside the box body.
