Description

Technical Field

[0001] This utility model relates to the field of concrete preparation technology, and more specifically to a concrete pouring proportioning device for a sloping roof structural layer. Background Technology

[0002] Concrete in the structural layer of a pitched roof plays a crucial role in supporting loads, providing thermal insulation, protecting the structure, drainage, and providing a foundation surface. These functions collectively ensure the overall performance of the roof system and the long-term reliability of the building. The preparation of concrete for the structural layer of a pitched roof requires the proportioning of various materials and then the uniform mixing of these raw materials using a mixer.

[0003] Most current mixers only have one feed pipe, and the discharge end of the feed pipe is stationary. This causes various raw materials to accumulate in one place when feeding them, and it takes a long time to mix them evenly, resulting in low mixing efficiency of the mixer as a whole.

[0004] In view of this, the present invention proposes a concrete pouring mix proportioning device for sloping roof structural layers to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a concrete pouring proportioning device for pitched roof structural layers to solve the problems existing in the background art.

[0007] The feeding and mixing assembly includes two feed pipes located at the top of the mixing tank. Each feed pipe has a second gate valve on its surface. The bottom end of the feed pipe has a bent pipe. The feed pipes are rotatably connected to the mixing tank. A central shaft is rotatably connected to the central axis of the mixing tank. A first gear is fixedly mounted on the surface of the central shaft, and a second gear is fixedly mounted on the surface of the feed pipe. The first and second gears mesh with each other. A stirring motor that drives the central shaft to rotate is located above the mixing tank. Stirring rods are fixedly mounted in a circumferential array on the surface of the central shaft.

[0008] As a further description of the above technical solution: the surface of the base is provided with four mounting holes, which are arranged in a rectangular array at the four corners of the base; by setting the mounting holes, expansion bolts are pre-embedded in the ground, and then the expansion bolts are inserted into the mounting holes, so that the base can be firmly positioned with respect to the ground, ensuring the stability of the overall device during use.

[0009] As a further description of the above technical solution: a protective cover is fixedly installed on the top of the mixing tank, the protective cover is placed over the surface of the first gear and the second gear, and the stirring motor is fixedly installed on the upper surface of the protective cover; by setting the protective cover, the first gear and the second gear can be shielded and protected, and items falling can be prevented from damaging the gears.

[0010] As a further description of the above technical solution: an arc-shaped plate is welded to the end of the stirring rod away from the central shaft, and the arc-shaped plate corresponds to the position of the discharge pipe; by setting the arc-shaped plate, the lateral flow of materials can be promoted, the mixing effect can be improved, and when the discharge pipe is opened to release materials, the arc-shaped plate can promote the discharge of concrete from the discharge pipe and increase the discharge speed.

[0011] As a further description of the above technical solution: the mixing tank and the support are movably installed. A swing assembly is provided on the surface of the support corresponding to the mixing tank. The swing assembly includes a drive box fixedly installed on the surface of the support.

A swing arm is fixedly installed on the outer wall of the mixing tank. The swing arm is rotatably connected to the support and the drive box respectively. A gear plate is fixedly installed on the surface of the swing arm. The rack and the gear plate mesh with each other. By setting up the swing assembly, during the mixing process, the periodic extension and retraction of the hydraulic rod, based on the meshing of the rack and the gear plate, can drive the swing arm and the mixing tank to swing back and forth, thereby further promoting the mixing efficiency of the material.

[0012] As a further description of the above technical solution: a control panel is fixedly mounted on the surface of the bracket, and the control panel is electrically connected to an external power source through wires.

[0013] As a further description of the above technical solution: the surface of the mixing tank is fitted with an observation window; by setting the observation window, it is convenient to observe the mixing state and volume of the raw materials inside the mixing tank.

[0017] 3. Compared with the existing technology, this concrete pouring proportioning device, by setting up a swing component, can drive the swing arm and mixing tank to swing back and forth in a reciprocating manner during the mixing process by periodically extending and retracting the hydraulic rod through the meshing of the rack and toothed disc, thereby further promoting the mixing efficiency of materials.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The concrete pouring mix proportioning device for the pitched roof structure layer involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figures 1 to 4 This utility model provides a concrete pouring mix proportioning device for a sloping roof structure layer, including a base 1. The surface of the base 1 has four mounting holes 10, which are arranged in a rectangular array at the four corners of the base 1.

[0025] By setting mounting holes 10 and pre-embedding expansion bolts in the ground, and then inserting the expansion bolts into the mounting holes 10, the base 1 can be firmly positioned to the ground, ensuring the stability of the entire device during use.

[0026] Two brackets 2 are symmetrically welded to the upper surface of the base 1. A control panel 20 is fixedly installed on the surface of the brackets 2. The control panel 20 is electrically connected to an external power source through wires.

[0027] A mixing tank 3 is provided between the two supports 2. A discharge pipe 4 is embedded on the bottom side of the front of the mixing tank 3. A first gate valve is provided on the surface of the discharge pipe 4. A feeding and mixing component is provided on the top of the mixing tank 3.

[0028] The feeding and mixing assembly includes two feed pipes 5 located at the top of the mixing tank 3. Each feed pipe 5 has a second gate valve on its surface. The bottom end of the feed pipe 5 is provided with a bent pipe 6. The feed pipe 5 is rotatably connected to the mixing tank 3. A central shaft 7 is rotatably connected to the central axis of the mixing tank 3. A first gear 12 is fixedly installed on the surface of the central shaft 7. A second gear 13 is fixedly installed on the surface of the feed pipe 5. The first gear 12 and the second gear 13 mesh with each other. A stirring motor 8 that drives the central shaft 7 to rotate is located above the mixing tank 3. Stirring rods 9 are fixedly installed in a circumferential array on the surface of the central shaft 7.

[0029] It is worth noting that this concrete pouring proportioning device adds different raw materials to the mixing tank 3 through two feed pipes 5 according to the proportions. At the same time as the raw materials are added, the mixing motor 8 drives the central shaft 7 and the mixing rod 9 to rotate, thus mixing the raw materials. The rotation of the central shaft 7 can drive the first gear 12 to rotate. Based on the meshing of the first gear 12 and the second gear 13, the feed pipe 5 can be driven to rotate. Under the action of the bent pipe 6 at the bottom of the feed pipe 5, the raw materials can fall more randomly into the mixing tank 3, thereby shortening the mixing time and achieving the purpose of improving the concrete pouring proportioning and mixing efficiency.

[0030] The surface of the mixing tank 3 is fitted with an observation window 21.

[0031] It is worth noting that by setting up the observation window 21, it is convenient to observe the mixing status and capacity of the raw materials inside the mixing tank 3. Regarding the capacity of the raw materials, the raw material level should be kept away from the bottom of the bent pipe 6 to ensure complete feeding and prevent blockage.

[0032] A protective cover 11 is fixedly installed on the top of the mixing tank 3. The protective cover 11 covers the surface of the first gear 12 and the second gear 13. The stirring motor 8 is fixedly installed on the upper surface of the protective cover 11.

[0033] Furthermore, by setting up a protective cover 11, the first gear 12 and the second gear 13 can be shielded and protected, preventing items from falling and damaging the gears.

[0034] An arc-shaped plate 14 is welded to the end of the stirring rod 9 away from the central shaft rod 7, and the arc-shaped plate 14 corresponds to the position of the discharge pipe 4.

[0035] Furthermore, by setting the arc plate 14, the lateral flow of materials can be promoted, the mixing effect can be improved, and when the discharge pipe 4 is opened to discharge materials, the arc plate 14 rotates with the central shaft 7, which can promote the discharge of concrete from the discharge pipe 4 and increase the discharge speed.

[0036] The mixing tank 3 and the support 2 are movably installed, and the surface of the support 2 is provided with a swing component corresponding to the mixing tank 3.

[0037] The swing assembly includes a drive box 15 fixedly mounted on the surface of the bracket 2. A hydraulic rod 16 is embedded at the bottom of the drive box 15. The telescopic end of the hydraulic rod 16 extends into the interior of the drive box 15 and is fixedly mounted with a rack 17. A swing arm 18 is fixedly mounted on the outer wall of the mixing tank 3. The swing arm 18 is rotatably connected to the bracket 2 and the drive box 15 respectively. A gear plate 19 is fixedly mounted on the surface of the swing arm 18. The rack 17 and the gear plate 19 mesh with each other.

[0038] It is worth noting that by setting up a swing assembly, during the mixing process, the hydraulic rod 16 extends and retracts periodically, and based on the meshing of the rack 17 and the toothed disc 19, the swing arm 18 and the mixing tank 3 can be driven to swing back and forth, thereby further promoting the mixing efficiency of the materials.

[0039] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
