Description

Technical Field

[0001] This invention belongs to the field of concrete pouring technology, and specifically provides a concrete pouring device for building construction. Background Technology

[0002] Before pouring concrete at a construction site, the concrete needs to be thoroughly mixed, which requires the use of concrete pouring equipment. Existing concrete pouring equipment usually only considers the convenience of mixing and pouring concrete, but does not take into account how to clean the inner wall of the concrete pouring equipment after use.

[0003] After the concrete pouring device has finished pouring the concrete, a lot of concrete residue adheres to the inner wall. If it is not cleaned in time, the concrete will solidify on the inner wall and be difficult to remove, which will seriously affect the subsequent use of the concrete pouring device.

[0004] Accordingly, there is a need in the art for a concrete pouring device for building construction to solve the above problems. Summary of the Invention

[0005] This invention proposes a concrete pouring device for building construction, which solves the problem in the prior art that the inner wall of the concrete pouring device cannot be cleaned in a timely and effective manner after use, resulting in concrete easily sticking to the inner wall of the pouring device.

[0006] The technical solution of this invention is implemented as follows: a concrete pouring device for building construction includes a mixing tank and a mixing device disposed within the mixing tank. The mixing tank has an inlet at the top and an outlet at the bottom. A water spraying device is disposed at the top of the mixing tank, comprising a mounting cover and a water spraying pipe. The water spraying pipe is mounted on the mounting cover. A water spray nozzle is opened at the top of the mixing tank. The mounting cover is installed at the water spray nozzle and covers it. The water spraying pipe is located on the side of the mounting cover facing the water spray nozzle, and spray holes are opened on the water spraying pipe.

[0007] The mixing tank is equipped with two cover plates, which are symmetrically positioned below the water spray nozzle and slidably connected to the inner wall of the mixing tank. A connecting rod is connected to the side of the cover plate facing the mixing tank. The connecting rod passes through the mixing tank and is connected to a drive motor. A gear is connected to the output end of the drive motor. An arc-shaped rack is fixedly connected to the outside of the mixing tank. The gear meshes with the arc-shaped rack. The drive motor drives the gear to move along the rack, causing the two cover plates to move away from or towards each other along the inner wall of the mixing tank.

[0008] In the preferred technical solution of the above-mentioned concrete pouring device for building construction, the water spray pipe is arranged in a continuous S-shape, and the water inlet end of the water spray pipe extends through the installation cover plate to the top of the installation cover plate, and the cover plate is in contact with the inner wall of the mixing tank.

[0009] In the preferred technical solution of the above-mentioned concrete pouring device for building construction, the discharge port of the mixing tank is connected to a discharge pipe, and a discharge direction adjustment device is provided at the bottom of the discharge pipe. The discharge direction adjustment device includes a valve body and a valve plate disposed in the valve body. The valve body is cylindrical and has an installation cavity, a blind cavity, and at least two discharge cavities. The installation cavity is located at the center of the valve body, and the blind cavity and discharge cavities are evenly distributed along the circumference of the installation cavity. The side wall of the valve body is connected to a conveying pipe corresponding to the number of discharge cavities. The discharge cavities are connected to the corresponding conveying pipes. The valve plate is disposed above the installation cavity and connected to a driving device. The driving device is disposed in the installation cavity. A material passage is opened on the valve plate. The transverse cross-sectional area of ​​the material passage is equal to the transverse cross-sectional area of ​​the discharge cavity and less than or equal to the transverse cross-sectional area of ​​the blind cavity. The driving device drives the valve plate to rotate, so that the material passage on the valve plate is aligned vertically with different discharge cavities.

[0010] In the preferred technical solution of the above-mentioned concrete pouring device for building construction, the driving device includes a second driving motor, which is located at the bottom of the valve body and fixedly connected to the valve body. The output shaft of the driving motor extends through the bottom of the valve body into the mounting cavity and is fixedly connected to the valve plate.

[0011] In the preferred technical solution of the above-mentioned concrete pouring device for building construction, a drive motor three and a gear two are installed on the discharge pipe. The gear two is sleeved on the discharge pipe and rotatably connected to the discharge pipe. A rotating disk is fixedly connected to the bottom of the gear two. An impact ball is connected to the rotating disk through a flexible rope. The output end of the drive motor three is connected to the gear three. The gear three meshes with the gear two. The drive motor three drives the gear three to drive the gear two to rotate around the discharge pipe. The gear two drives the impact ball to rotate around the discharge pipe so that the impact ball impacts the conveying pipe.

[0012] In the preferred technical solution of the above-mentioned concrete pouring device for building construction, the conveying pipe is inclined downward from the end closer to the valve body to the end farther away from the valve body.

[0013] Beneficial effects: This invention, by setting up a water spray pipe and spray nozzles, sprays water into the mixing tank of the concrete pouring device to spray and clean the concrete adhering to the inner wall of the mixing tank. Combined with the mixing of the mixing device, it can effectively clean the residual concrete in the mixing tank, preventing the concrete from solidifying on the inner wall of the mixing tank and affecting its normal use. Moreover, this invention is equipped with a cover plate, which covers the water spray pipe during concrete mixing to prevent concrete from adhering to the spray nozzles and clogging them. When cleaning is required, the cover plate is opened to both sides to expose the water spray pipe, allowing the water sprayed from the pipe to smoothly enter the mixing tank.

[0014] The cover plate fits snugly against the inner wall of the mixing tank, allowing it to scrape away the concrete adhering to the inner wall of the mixing tank as it opens to the sides, thus further improving the cleaning effect of residual concrete.

[0015] This invention, by setting up a discharge direction adjustment device, can change the discharge direction without moving the mixing tank, thus facilitating concrete pouring.

[0016] This invention uses impact balls to drive the balls to rotate, causing them to impact each transport pipe, which helps to remove concrete adhering to the inner wall of the pipe. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Specific embodiments of the concrete pouring device for building construction of the present invention:

[0025] like Figure 1 As shown, a concrete pouring device for building construction includes a mixing tank 1 and a mixing device 2 installed inside the mixing tank 1. The mixing tank 1 has an inlet 11 at the top and an outlet at the bottom. The mixing device 2 includes a drive motor 21 and a mixing shaft 22 connected to the drive motor 21. Multiple mixing rods 23 are spaced apart on the mixing shaft 22.

[0026] A water spraying device 3 is installed on the top of the mixing tank 1. The water spraying device 3 includes a mounting cover plate 31 and a water spraying pipe 32. The water spraying pipe 32 is installed on the mounting cover plate 31 and is arranged in a continuous S-shape. The water inlet end of the water spraying pipe 32 extends through the mounting cover plate 31 and above the mounting cover plate 31, and the water inlet end is connected to a water pump. A water spraying nozzle is opened on the top of the mixing tank 1. The mounting cover plate 31 is installed at the water spraying nozzle of the mixing tank 1 and seals and covers the water spraying nozzle. The water spraying pipe 32 is located on the side of the mounting cover plate 31 facing the water spraying nozzle, and spray holes are opened on the water spraying pipe 32.

[0027] like Figure 2 and Figure 3 As shown, two cover plates 4 are provided inside the mixing tank 1. The two cover plates 4 are symmetrically arranged below the water spray nozzle. Two U-shaped limiting plates 41 are fixedly connected to the inner wall of the mixing tank 1. The opening of the U-shaped limiting plate 41 faces the inner wall of the mixing tank 1. The cover plate 4 slides between the U-shaped limiting plate 41 and the inner wall of the mixing tank 1, and the cover plate 4 is in contact with the inner wall of the mixing tank 1.

[0028] A connecting rod is connected to the side of the cover plate 4 facing the tank wall of the mixing tank 1. The connecting rod passes through the mixing tank 1 and is connected to a drive motor (not shown in the figure). The output end of the drive motor is connected to a gear 42. An arc-shaped rack 43 is fixedly connected to the outside of the mixing tank 1. The side of the arc-shaped rack 43 with teeth faces the mixing tank 1. The gear 42 meshes with the arc-shaped rack 43. The drive motor drives the gear 42 to move along the arc-shaped rack 43, causing the two cover plates 4 to move along the inner wall of the mixing tank 1 in a direction away from or towards each other.

[0029] like Figure 1 and Figure 4As shown, the discharge port of the mixing tank 1 is connected to a discharge pipe 5. A discharge direction adjustment device 60 is provided at the bottom of the discharge pipe 5. The discharge direction adjustment device 60 includes a valve body 6 and a valve plate 61 disposed inside the valve body 6. The valve body 6 is cylindrical, and the top of the valve body 6 is connected to the discharge pipe 5. The valve body 6 is provided with an installation cavity 62, a blind cavity 63, and three discharge cavities 64. The installation cavity 62 is located at the center of the valve body 6. The blind cavity 63 and the discharge cavities 64 are the same size and are evenly distributed along the circumference of the installation cavity 62. The side wall of the valve body 6 is connected to a conveying pipe 65 corresponding to the number of discharge cavities 64. The discharge cavities 64 are connected to the corresponding conveying pipes 65. The conveying pipes 65 are inclined downward from the end closer to the valve body 6 to the end farther away from the valve body 6.

[0030] A valve plate 61 is positioned above the mounting cavity 62 and connected to a driving device. The valve plate 61 has a feed port 611, the transverse cross-sectional area of ​​which is the same as that of the discharge cavity 64. The driving device includes a second drive motor 7, which is located at the bottom of the valve body 6 and fixedly connected to it. The output shaft of the drive motor extends through the bottom of the valve body 6 into the mounting cavity 62 and is fixedly connected to the valve plate 61. The driving device drives the valve plate 61 to rotate, aligning the feed port 611 on the valve plate 61 vertically with the different discharge cavities 64.

[0031] Continue reading Figure 1 The discharge pipe 5 is equipped with a drive motor 8 and a gear 9. The gear 9 is sleeved on the discharge pipe 5 and rotatably connected to the discharge pipe 5 via bearings. A rotating disk 91 is fixedly connected to the bottom of the gear 9, and an impact ball 92 is connected to the rotating disk 91 via a flexible rope. The output end of the drive motor 8 is connected to the gear 81, which meshes with the gear 9. The drive motor 8 drives the gear 81 to rotate the gear 9 around the discharge pipe 5, and the gear 9 drives the impact ball 92 to rotate around the discharge pipe 5, so that the impact ball 92 impacts the conveying pipe 65.

[0032] The specific working process of the concrete pouring device for building construction of the present invention is as follows: During mixing, the second drive motor 7 drives the valve plate 61 to rotate until the material outlet 611 on the valve plate 61 is aligned with the blind cavity 63. At this time, material cannot be discharged, allowing the material to be fully mixed in the mixing tank 1. During discharge, the valve plate 61 is adjusted according to the direction of the site to be poured, so that the second drive motor 7 drives the valve plate 61 to rotate until the material outlet 611 on the valve plate 61 is vertically aligned with the discharge cavity 64 in the corresponding direction. The concrete enters the discharge cavity 64 through the material outlet 611 and is transported to the site to be poured through the conveying pipe 65 connected to the discharge cavity 64. During mixing and discharge, the two cover plates 4 are located below the water spray nozzle, completely blocking the water spray pipe 32. When the concrete in the mixing tank 1 needs to be cleaned after use, the first drive motor drives the gear 42 to move along the arc rack 43, causing the two cover plates 4 to move away from each other, thus discharging the water spray nozzle. With the water pipe 32 exposed, the cover plate 4 scrapes away the concrete adhering to the inner wall of the mixing tank 1 during its movement. The water pump connected to the water spray pipe 32 is turned on, and water is pumped into the water spray pipe 32. The water is sprayed into the mixing tank 1 through the spray holes on the water spray pipe 32. The mixing device 2 continuously stirs, thus cleaning the concrete adhering to the mixing device 2 and the mixing tank 1. At the same time, the drive motor 7 and the drive motor 8 are started. The drive motor 7 drives the valve plate 61 to rotate continuously, thereby introducing the cleaning water into different discharge chambers 64 to clean the different discharge chambers 64 and the conveying pipe 65. The drive motor 8 drives the gear 9 to rotate through the gear 81. The rotating disk 91 on the gear 9 drives the impact ball 92 to rotate. The impact ball 92 impacts the conveying pipe 65, causing the concrete adhering to the pipe wall of the conveying pipe 65 to fall off. After cleaning, the two cover plates 4 are moved closer to each other to cover the water spray pipe 32.

[0033] This invention sprays water into the mixing tank of a concrete pouring device to clean the concrete adhering to the inner wall of the mixing tank. Combined with the mixing of the mixing device, this effectively cleans the residual concrete in the mixing tank, preventing it from solidifying on the inner wall and affecting its normal use. Furthermore, this invention includes a cover plate that blocks the water spray pipe during concrete mixing, preventing concrete from adhering to the spray nozzles and clogging them. When cleaning is required, the cover plate is opened to the sides to expose the water spray pipe, allowing the water sprayed from the pipe to smoothly enter the mixing tank.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
