Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a clear-faced concrete construction device. Background Art

[0002] Fair-faced concrete is a modernist architectural expression, also known as decorative concrete for its exceptional decorative effect. Its aesthetic appearance, smooth surface, and lack of need for post-finishing make it widely used, particularly in high-end buildings, bridges, tunnels, and other projects. Fair-faced concrete construction equipment is specialized equipment or systems used for the construction of fair-faced concrete (i.e., concrete with a smooth surface and no noticeable defects).

[0003] For example, the Chinese utility model patent with the announcement number CN217752043U discloses a precise proportioning device for concrete used in clear water construction. The device can conveniently adjust the position of each metering cylinder through the station adjustment component, so that the feeding hopper can be easily moved to the feeding position, thereby facilitating feeding.

[0004] However, although the device can adjust the position of the metering cylinder to feed materials during actual use, a large amount of materials will be discharged at one time during feeding, which makes the materials easily accumulate, thereby affecting the mixing effect of the plain concrete.

[0005] In summary, there is a need for a clear concrete construction device that can intermittently block the discharge of materials. Utility Model Content

[0006] The utility model aims to provide a device for constructing bare concrete, which blocks the discharge port at the bottom of a feeding tank with a baffle plate, and opens the baffle plate by deflecting it downward, so that the material inside the feeding tank is automatically discharged, thereby achieving the purpose of automatic intermittent discharge.

[0011] A further preferred technical solution is that the gear ring assembly includes a gear ring arranged on the top cover, a motor fixedly connected to the storage barrel, a rotor of the motor is coaxially fixedly connected to a gear, and the gear and the gear ring are meshed.

[0012] A further preferred technical solution is that: a hollow tube is rotatably connected to the inner side of the feeding tank, a vertical rod is movably connected to the inner side of the hollow tube, and the bottom end of the vertical rod extends to the outside of the hollow tube, and a plurality of stirring rods are fixedly connected to the outside of the hollow tube.

[0013] A further preferred technical solution is that a second connecting rod is hinged between the vertical rod and the baffle plate through a hinge, the top end of the vertical rod is movably connected to a ball through a connecting piece, and a spiral groove for installing the ball is provided on the inner side of the hollow tube.

[0014] A further preferred technical solution is that: the inner side of the feeding tank is horizontally movably connected with a measuring plate, a feeding hopper is provided above the feeding tank, a connecting pipe is fixedly connected between the feeding hopper and the measuring plate, and the connecting pipe is slidingly connected to the feeding tank, a fixing sleeve is fixedly provided on the connecting pipe, the top of the storage barrel is circumferentially connected with a screw rod, and the screw rod and the fixing rod are threadedly connected.

[0015] A further preferred technical solution is that: an observation port is provided on one side of the feeding tank, and a transparent glass is fixedly connected to the observation port.

[0018] A further preferred technical solution is that a discharge valve is provided at the bottom discharge port of the storage barrel.

[0019] A further preferred technical solution is that the bottom of the material blocking plate is in contact with the annular sector-shaped fixing plate.

[0020] In summary, the present invention has the following advantages:

[0021] The material discharging opening at the bottom of the feeding tank is automatically discharged, thereby achieving the purpose of automatic intermittent discharging, further ensuring the uniformity of material mixing and improving the mixing effect of clear-water concrete.

[0022] 2. During the process of opening and closing the baffle plate, the utility model utilizes the movable cooperation between the vertical rod and the hollow tube, and the hinged effect between the vertical rod and the baffle plate and the second connecting rod, so that the vertical rod can be driven to move vertically. The movement of the vertical rod will drive the ball to move together. The cooperation between the ball and the spiral groove can be utilized to drive the hollow tube to rotate.

[0031] Please combine Figure 1-4 , a plain concrete construction device of this embodiment includes:

[0032] Storage barrel 1, the top of the storage barrel 1 is rotatably connected to the top cover 2, the outside of the top cover 2 is fixedly connected to the gear ring 3, the outside of the storage barrel 1 is fixedly connected to the motor, the rotor end of the motor is coaxially fixedly connected to the gear 4 and the gear 4 is meshed with the gear ring 3, the top of the top cover 2 is equidistantly circumferentially fixedly connected to the feeding tank 5, the bottom of the storage barrel 1 and the bottom of the feeding tank 5 are both funnel-shaped structures, which are convenient for the rapid and complete discharge of materials and clear-water concrete. The center of the bottom of the top cover 2 is fixedly connected to the stirrer 10, which can stir the clear-water concrete and improve the uniformity of the mixing. A discharge valve is provided at the bottom discharge port of the storage barrel 1;

[0033] The intermittent unloading component includes a baffle plate 101 hinged at the bottom discharge port of the feeding tank 5 through a hinge, and the bottom of the top cover 2 is fixedly connected to three groups of slide rods 102 at equal intervals through a connecting seat, and the outer sliding connection of the slide rod 102 is connected to a slider 103, and the slider 103 and the baffle plate 101 on the same side are symmetrically hinged with a first connecting rod 104 through a hinge, and the outer sleeve of the slide rod 102 is provided with a spring 105, and the two ends of the spring 105 are fixedly connected to the connecting seat and the slider 103 respectively, and the upper part of the inner cavity of the storage barrel 1 is fixedly connected to an annular fan-shaped fixed plate 106 at equal intervals in the circumferential direction, and the bottom of the baffle plate 101 is in contact with the surface of the annular fan-shaped fixed plate 106.

[0034] The feeding tank 5 is internally rotatably connected to a hollow tube 201, the hollow tube 201 is internally movably connected to a vertical rod 202 and the bottom end of the vertical rod 202 extends to the outside of the hollow tube 201, the outside of the hollow tube 201 is equidistantly and circumferentially fixedly connected to a stirring rod 203, the vertical rod 202 and the baffle plate 101 are symmetrically hinged with a second connecting rod 204 through a hinge, the top of the vertical rod 202 is symmetrically and movably connected to a ball 205 through a connecting piece, the inner wall of the hollow tube 201 is provided with a spiral groove 206 corresponding to the position of the ball 205, and the length of the stirring rod 203 decreases from top to bottom.

[0035] The implementation principle of a clear water concrete construction device in the embodiment of the present application is as follows: first, the material is added to the feeding tank 5, and then the motor is started, and the gear 4 is driven to rotate by the motor, and the meshing action between the gear 4 and the gear ring 3 is utilized, and the rotation cooperation between the top cover 2 and the storage barrel 1 is used to drive the top cover 2 to rotate. During the rotation of the top cover 2, when the baffle plate 101 slides on the surface of the annular sector fixing plate 106, the baffle plate 101 is blocked by the annular sector fixing plate 106, so that the material outlet at the bottom of the feeding tank 5 can be opened. The material is blocked to prevent a large amount of material from being discharged at one time. When the baffle plate 101 moves to the gap between the two adjacent sets of annular sector fixing plates 106, due to the gravity of the material and the elasticity of the spring 105, and the sliding cooperation between the slider 103 and the slide rod 102, the hinged action between the slider 103 and the baffle plate 101 and the first connecting rod 104, the baffle plate 101 will deflect downward and open. At this time, the material inside the feeding tank 5 will be automatically discharged, thereby achieving the purpose of automatic intermittent unloading, further The uniformity of material mixing is ensured and the mixing effect of the clear water concrete is improved. As the top cover 2 continues to rotate, when the baffle plate 101 contacts the next set of annular sector fixing plates 106, the baffle plate 101 will automatically deflect upward until it is parallel to the annular sector fixing plates 106 due to the obstruction of the annular sector fixing plates 106. At this time, the discharge port at the bottom of the feeding tank 5 will be closed again. At the same time, in the process of opening and closing the baffle plate 101, the vertical rod 202 is used to cooperate with the hollow tube 201. 2 and the hinged connection between the baffle plate 101 and the second connecting rod 204, which can drive the vertical rod 202 to move vertically. The movement of the vertical rod 202 will drive the ball 205 to move together. The cooperation between the ball 205 and the spiral groove 206 can drive the hollow tube 201 to rotate. The rotation of the hollow tube 201 drives the stirring rod 203 outside it to rotate, so that the material can be stirred to prevent the material from being blocked. Finally, the discharge valve is opened to discharge the mixed clear-water concrete out of the storage barrel 1.

[0036] The top of material storage barrel 1 is equidistantly connected to a screw rod 9 for circumferential rotation, and the screw rod 9 is threadedly connected to the fixing piece. An observation port is provided on one side of the material storage barrel 1, and a transparent glass is fixedly connected to the observation port. The transparent glass is provided with a scale. By rotating the screw rod 9, the fixing piece threadedly connected thereto is driven to move vertically, so that the measuring plate 6 can be driven to move vertically inside the material storage barrel 5. The capacity of the material storage barrel 1 at this time can be obtained by observing the scale aligned with the bottom of the measuring plate 6. By adding material to the material storage barrel 1, the material will enter the cavity between the bottom of the measuring plate 6 and the material storage barrel 1 through the connecting pipe 8, thereby facilitating the control of the amount of material added, thereby ensuring the accuracy of the proportion of the clear water concrete.
