Description

Technical Field

[0001] This utility model relates to the field of concrete grouting technology, and in particular to a concrete grouting device. Background Technology

[0002] Concrete is a composite material made by mixing cementitious materials (cement), aggregates (sand, stone), water, and optional admixtures and additives in a specific ratio. Its core principle is that the cement hydration reaction forms a cementitious paste, which binds the aggregates together as a whole.

[0003] A search revealed existing concrete grouting devices, such as the one disclosed in CN119077958A. This device uses a rodless cylinder to move cutting blades left and right, causing two blades to cut openings at the bottom of the cement bag. These openings expand laterally under the pressure of the cement, allowing the cement to fall into the pretreatment box. This achieves a closed-loop, automatic bag-opening and feeding effect, avoiding the dust floating and respiratory health issues caused by manual bag opening. However, the spiral discharge cylinder of this device is relatively fixed in position, resulting in a small filling area, a long distance the device can be moved, and a long grouting time, leading to low work efficiency. Therefore, this paper proposes a concrete grouting device. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low work efficiency caused by the relatively fixed position of the spiral discharge cylinder, the small range that concrete can fill, the long distance that the pushing device can move, and the long time required for grouting. Therefore, a concrete grouting device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A concrete grouting device includes a support plate, a mixing tank fixedly connected to the top of the support plate, a circular cylinder disposed inside the mixing tank, a first bevel gear and a second bevel gear disposed inside the circular cylinder, a mixing rod disposed inside the mixing tank, and a mixing mechanism disposed inside the circular cylinder for mixing concrete by means of the first and second bevel gears and the mixing rods. A discharge cylinder is disposed below the support plate, and a U-shaped plate is fixedly connected to the bottom of the support plate. A connecting ring is disposed on the U-shaped plate, and a moving mechanism is disposed on the U-shaped plate for reciprocating movement of the discharge cylinder by means of the connecting ring.

[0007] Preferably, the stirring mechanism includes a first drive motor installed at the top of the inner cylinder, the output end of the first drive motor is connected to a first rotating rod, the first rotating rod is fixedly connected to a first bevel gear, the inner cylinder is rotatably connected to a second rotating rod, one end of the second rotating rod is fixedly connected to a second bevel gear, the second bevel gear meshes with the first bevel gear, and the second rotating rod is fixedly connected to a stirring rod.

[0008] Preferably, a circular plate is fixedly connected inside the mixing tank, and the circular cylinder is rotatably connected to the circular plate. A second drive motor is installed on the top of the mixing tank, and a third rotating rod is rotatably connected to the top of the mixing tank and fixedly connected to the output end of the second drive motor. One end of the third rotating rod is fixedly connected to the top of the circular cylinder.

[0009] Preferably, the moving mechanism includes a third drive motor mounted on one side of the U-shaped plate, a fourth rotating rod rotatably connected to the output end of the third drive motor, a rotating plate fixedly connected to one end of the fourth rotating rod, a connecting column fixedly connected to one side of the rotating plate, a limit block fixedly connected to one end of the connecting column, a connecting ring sleeved on the connecting column, a connecting plate fixedly connected to the connecting ring, a sliding block fixedly connected to the connecting plate, a limit frame fixedly connected to one side of the U-shaped plate, the sliding block slidably connected to the limit frame, a moving plate fixedly connected to one side of the sliding block, a connecting sleeve fixedly connected to one side of the moving plate, and the discharge cylinder installed inside the connecting sleeve.

[0010] Preferably, a discharge pipe is fixedly connected to the bottom of the mixing tank, one end of the discharge pipe is connected to a conveying pipe, one end of the conveying pipe is fixedly connected to a discharge cylinder, and a solenoid valve is installed on the discharge pipe;

[0011] A placement frame is fixedly connected to the top of the support plate, a water storage tank is placed on the placement frame, a water pump is installed inside the water storage tank, the water pump is connected to a water outlet pipe, and one end of the water outlet pipe is fixedly connected to the mixing tank.

[0012] Preferably, the mixing tank has a feed inlet at the top, a support rod is fixedly connected to the bottom of the support plate, a caster wheel is installed at the bottom of the support rod, and a handle is fixedly connected to the top of the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When using this equipment, the moving mechanism allows the connecting ring to drive the sliding block to slide back and forth along the limit frame via the connecting plate during grouting. The sliding block drives the moving plate to move back and forth, and the moving plate drives the discharge cylinder to move back and forth via the connecting sleeve. This increases the range of concrete grouting, reduces the distance that needs to be moved by the device, shortens the grouting time, and increases work efficiency.

[0015] 2. When this equipment is in use, the meshing of the first and second bevel gears through the stirring mechanism causes the first rotating rod to drive the second rotating rod to rotate. The second rotating rod drives the stirring rod to stir the cement raw materials and water. The third rotating rod drives the cylindrical cylinder to rotate inside the mixing drum, thereby driving multiple sets of stirring rods to rotate inside the mixing drum, resulting in high efficiency in mixing cement raw materials and water.

[0025] A discharge cylinder 7 is provided below the support plate 1. A U-shaped plate 8 is fixedly connected to the bottom of the support plate 1. A connecting ring 9 is provided on the U-shaped plate 8. The U-shaped plate 8 is provided with a moving mechanism that drives the discharge cylinder 7 to reciprocate through the connecting ring 9. A spiral plate is installed inside the discharge cylinder 7. The spiral plate discharges concrete.

[0026] The mixing mechanism includes a first rotating rod connected to the output end of the first drive motor 10. The first rotating rod is fixedly connected to the first bevel gear 4.

Through the meshing of the first bevel gear 4 and the second bevel gear 5, the first rotating rod can drive multiple second rotating rods 11 to rotate together, and at the same time, the cement in the mixing tank 2 is stirred, so that the cement and water can be fully mixed.

[0027] A circular plate 12 is fixedly connected inside the mixing tank 2. A circular cylinder 3 is rotatably connected to the circular plate 12. A second drive motor 13 is installed on the top of the mixing tank 2. A third rotating rod 14 is rotatably connected to the top of the mixing tank 2 and fixedly connected to the output end of the second drive motor 13. One end of the third rotating rod 14 is fixedly connected to the top of the circular cylinder 3. By rotating on the circular plate 12 through the third rotation, the circular cylinder 3 is driven to rotate, which in turn drives multiple sets of stirring rods 6 to rotate inside the mixing tank 2, further improving the stirring efficiency.

A connecting ring 9 is sleeved on the connecting post 18. The two sides of the connecting ring 9 are distributed and abut against the rotating plate 17 and the limiting block 19. The rotation of the fourth rotating rod 16 drives the connecting post 18 and the limiting block 19 to move, and the connecting post 18 then drives the connecting ring 9 to move.

[0029] A connecting ring 9 is fixedly connected to a connecting plate, and a sliding block 20 is fixedly connected to the connecting plate. A limit frame 21 is fixedly connected to one side of the U-shaped plate 8. The sliding block 20 is slidably connected to the limit frame 21.

[0030] A sliding block 20 is fixedly connected to a movable plate 22 on one side, and a connecting sleeve 23 is fixedly connected to a side of the movable plate 22. The discharge cylinder 7 is installed inside the connecting sleeve 23. The movable plate 22 drives the discharge cylinder 7 to move back and forth through the connecting sleeve 23, thereby increasing the range of concrete that can be grouted.

The conveying pipe 24 is relatively soft, and one end can move with the discharge cylinder 7. The length is also sufficient for one end to move back and forth. The solenoid valve is used to control the concrete to fall from the discharge pipe.

[0033] A placement frame is fixedly connected to the top of the support plate 1. A water storage tank 25 is placed on the placement frame. A water pump is installed inside the water storage tank 25. The water pump is connected to a water outlet pipe 26. One end of the water outlet pipe 26 is fixedly connected to the mixing tank 2. The water pump is connected to a water suction pipe. The water pump controls the water suction pipe to draw water, which is then transported from the water outlet pipe 26 to the mixing tank 2 to be mixed with cement.

[0034] The top of the mixing tank 2 is provided with a feed inlet 27. The bottom of the support plate 1 is fixedly connected with a support rod, and the bottom of the support rod is equipped with casters.

[0036] The specific models and specifications of the first drive motor 10, the second drive motor 13, and the third drive motor 15 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation methods adopt existing technologies in this field, so they will not be elaborated here.

[0037] The working principle of this utility model:

[0038] Cement raw materials are added into the mixing drum 2 through the feed inlet 27. Water is then pumped into the mixing drum 2 through the water outlet pipe 26 via the water pump in the water storage tank 25. Subsequently, the first drive motor 10 drives the first rotating rod to rotate, which in turn drives the first bevel gear 4 to rotate. The first bevel gear 4 drives the second bevel gear 5 to rotate, which in turn drives the second rotating rod 11 to rotate. The second rotating rod 11 drives the rotating rod to rotate. At the same time, the second drive motor 13 drives the third rotating rod 14 to rotate, which in turn drives the cylindrical cylinder 3 to rotate inside the mixing drum 2. This, in turn, drives multiple sets of mixing rods 6 to rotate inside the mixing drum 2, thus mixing the cement raw materials and water.

[0039] After mixing, the solenoid valve controls the concrete to be transported from the discharge pipe and water pipe to the discharge cylinder 7. The discharge cylinder 7 discharges the concrete for grouting. At the same time as grouting, the third drive motor 15 drives the fourth rotating rod 16 to rotate. The fourth rotating rod 16 drives the rotating plate 17 to rotate. The rotating plate 17 drives the connecting column 18 and the limiting block 19 to rotate. The connecting column 18 drives the connecting ring 9 to move. The connecting ring 9 drives the sliding block 20 to slide back and forth along the limiting frame 21 through the connecting plate. The sliding block 20 drives the moving plate 22 to move back and forth. The moving plate 22 drives the discharge cylinder 7 to move back and forth through the connecting sleeve 23, increasing the range of concrete grouting.
