Description

Technical Field

[0001] This utility model belongs to the field of concrete pouring technology, specifically a pouring device for indoor floor concrete. Background Technology

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. In civil engineering, concrete and other materials are poured into a mold to form a predetermined shape. When pouring concrete, the free height of the concrete should not exceed 2m. When it exceeds 3m, corresponding measures should be taken. At present, when pouring concrete indoors, concrete pouring machines are generally used to improve efficiency. However, when the indoor area is small, the concrete pouring machine is too large to move easily, so it cannot be used to pour concrete. In this case, a small device is generally used for concrete pouring.

[0003] Chinese Patent Application No. 202221901885.9 discloses an indoor floor concrete pouring device, including a trolley with a material tank fixedly connected to it. The material tank is connected to a conveying pipe fixedly connected to the trolley via a mud pump. One end of the conveying pipe is rotatably connected to a discharge pipe rotatably connected to the trolley. This indoor floor concrete pouring device, by setting up a trolley and a smoothing component set on the trolley, allows concrete to be poured out by pushing the trolley. During the pouring process, the smoothing component automatically pre-smooths the poured concrete, eliminating the need for manual pouring and smoothing, thus improving construction efficiency. This solves the problem of low construction efficiency due to manual operation when pouring concrete in small areas in the prior art.

[0004] However, the above-mentioned indoor ground concrete pouring device has the following problems in actual use: the concrete has strong adhesion and easily adheres to the pipes and inner walls of the tank. After drying, it affects the volume and is not conducive to the use of the device.

[0005] Therefore, a pouring device for indoor floor concrete is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a concrete pouring device for indoor floors, which has the advantages of cleaning concrete adhering to the inner wall of the cart and avoiding the accumulation of deposits that affect the use of the cart.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a pouring device for indoor floor concrete, comprising a trolley, a baffle is provided at the front opening of the trolley, a mixing component is provided on the baffle, a lifting component is connected to the baffle, and a matching scraper is provided near the rear side of the inner cavity of the trolley, the scraper is connected to a pushing component.

[0008] Preferably, the trolley includes a body, wheels are mounted on the bottom of the body, and a push rod is fixedly connected to the rear side of the body.

[0009] Preferably, a discharge port is fixedly connected to the front end of the vehicle body, and a limit stop bar is fixedly connected to the position of the vehicle body corresponding to the baffle.

[0010] Preferably, the stirring assembly includes a stirring motor mounted on a baffle, the output end of the stirring motor is connected to a central shaft, and a plurality of corresponding stirring rods are fixed on the central shaft.

[0012] Preferably, the first fixed shell has a first limiting through groove that matches the lifting rod, and the lifting rod passes through the first limiting through groove.

[0013] Preferably, the pushing assembly includes a second fixed housing that is fixedly connected to the trolley, a second motor that is installed at the rear end of the second fixed housing, a second lead screw that is connected to the output end of the second motor, a second nut that is threadedly connected to the second lead screw, and a scraper that is fixedly connected to the second nut through a second connecting rod.

[0014] Preferably, the second fixed shell has a second limiting through groove that matches the second connecting rod, and the second connecting rod passes through the second limiting through groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a scraper and a pushing component. The scraper can scrape off the concrete adhering to the inner wall of the cart, avoiding the accumulation of a large amount of adhering material after long-term use, so as to avoid affecting the volume of the cart and causing waste of concrete.

[0032] Specifically, the trolley 1 includes a body 101, wheels 102 are installed at the bottom of the body 101, and a push rod 103 is fixedly connected to the rear side of the body 101.

[0033] Furthermore, a discharge port 7 is fixedly connected to the front end of the vehicle body 101, and a limit stop bar 8 is fixedly connected to the position corresponding to the baffle 2 inside the vehicle body 101.

[0034] Furthermore, the mixing assembly 3 includes a mixing motor 301 mounted on the baffle 2. The output end of the mixing motor 301 is connected to a central shaft 302. Multiple corresponding mixing rods 303 are fixed on the central shaft 302 to mix the concrete transported in the trolley 1. This helps to improve the cohesiveness of the concrete, making it less prone to segregation during transportation and pouring. At the same time, mixing can also improve the water retention of the concrete and reduce water exudation.

[0035] It is worth noting that the lifting assembly 4 includes a first fixed housing 401 fixedly connected to the trolley 1. A first motor 402 is installed at the bottom of the first fixed housing 401. A first lead screw 403 is connected to the output end of the first motor 402. A first nut 404 is threadedly connected to the first lead screw 403. A lifting rod 405 is fixedly connected to the first nut 404. The lifting rod 405 is fixedly connected to the baffle 2 through a first connecting rod 406.

[0036] It is worth noting that the first fixed shell 401 has a first limiting groove 9 that matches the lifting rod 405, and the lifting rod 405 passes through the first limiting groove 9.

[0037] It is worth mentioning that the pushing component 6 includes a second fixed housing 601 fixedly connected to the trolley 1. A second motor 602 is installed at the rear end of the second fixed housing 601. A second lead screw 603 is connected to the output end of the second motor 602. A second nut 604 is threadedly connected to the second lead screw 603. The second nut 604 is fixedly connected to the scraper 5 through a second connecting rod 605. The scraper 5 can scrape off the concrete adhering to the inner wall of the trolley 1, avoiding the accumulation of a large amount of adhering material after long-term use, so as to avoid affecting the volume of the trolley 1 and causing concrete waste.

[0038] It is worth emphasizing that the second fixed shell 601 is provided with a second limiting through groove 10 that matches the second connecting rod 605, and the second connecting rod 605 passes through the second limiting through groove 10.

[0040] Working principle and process: Place concrete on the trolley 1, start the mixing motor 301 of the mixing assembly 3, and then the central shaft 302 drives the mixing rod 303 to rotate, thus mixing the concrete. This helps improve the cohesiveness of the concrete, making it less prone to segregation during transportation and pouring. At the same time, mixing also improves the water retention of the concrete and reduces water seepage. Push the trolley 1 to the location where the concrete needs to be poured indoors, turn off the mixing motor 301 of the mixing assembly 3, and start the first motor 402 of the lifting assembly 4, which in turn rotates the first lead screw 403, causing the first... When nut 404 moves, lifting rod 405 drives baffle 2 to move upward via first connecting rod 406, causing concrete in cart 1 to flow out from the original position of baffle 2 and then be discharged through outlet 7. This starts the second motor 602 of push assembly 6, causing second lead screw 603 to rotate. Then, second nut 604 drives scraper 5 to move via second connecting rod 605, thus pushing away residual concrete in cart 1 and scraping away concrete adhering to the inner wall of cart 1. This prevents the accumulation of a large amount of adhering material over a long period of use, thereby avoiding affecting the volume of cart 1 and causing concrete waste.
