Description

Technical Field

[0001] This utility model relates to the field of high load-bearing permeable concrete pouring technology, specifically a pouring device for high load-bearing permeable concrete. Background Technology

[0002] High-load-bearing permeable concrete is a new type of building material characterized by high permeability and high load-bearing capacity. It is formed by uniformly coating coarse aggregate with a cement-based binder, creating a continuous honeycomb structure that provides excellent air and water permeability while maintaining a relatively light weight. This material ensures high permeability while also possessing high strength and durability, making it particularly suitable for applications requiring high load-bearing capacity, such as parking lots and airport runways. High-load-bearing permeable concrete pouring equipment is used during its pouring process.

[0003] Some high-load permeable concrete pouring devices suffer from hardened concrete residue on the inner wall of the pouring outlet after prolonged use, which can easily block the outlet and affect subsequent concrete pouring. Therefore, they do not meet the current requirements. To address this, we propose a high-load permeable concrete pouring device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pouring device for high load-bearing permeable concrete. The technical solution of this utility model is as follows:

[0005] A high-load-bearing permeable concrete pouring device includes a base and a concrete storage tank. A support seat is fixedly provided at the upper end of the base, and the concrete storage tank is located inside the upper end of the support seat. A feed inlet is provided on one side of the upper end of the concrete storage tank. A pouring port extending through to the bottom end of the concrete storage tank is fixedly connected to the bottom end of the concrete storage tank. A shaft is rotatably connected inside the concrete storage tank. Several mixing blades are connected to the outer surface of the shaft. A first scraper is connected to both sides of the bottom end of the shaft through connecting rods. A support frame is provided at the upper end of the base, located on one side of the support seat. A second scraper extending through to the bottom end of the base is movably provided inside the support frame.

[0006] Preferably, the top end of the shaft extends through to the outer side of the top of the concrete storage tank. A driven gear is fixedly connected to the outer surface of the shaft at one end of the outer side of the concrete storage tank. A fixed frame is fixedly provided on one side of the driven gear and at the top of the concrete storage tank. The bottom end of the fixed frame is connected to a driving gear via a motor drive, and the outer surface of the driving gear meshes with the outer surface of the driven gear.

[0007] Preferably, the shaft has a vertical through hole inside, and symmetrical movable grooves are formed on both sides of the through hole and inside the shaft near the bottom end. Sliding plates are slidably connected inside the movable grooves on both sides.

[0008] Preferably, a spring is fixedly connected between the side of the two sliding plates that is far apart from each other and the inner wall of the movable groove, and a limiting block is fixedly connected to the side of the two sliding plates that is close to each other, and the end of the limiting block that is far away from the sliding plate extends through the through hole.

[0009] Preferably, a movable rod is slidably connected inside the through hole. Symmetrical limiting grooves are provided on both the upper and lower sides of the movable rod near the bottom. One end of the limiting block extending through the through hole is inserted into the corresponding limiting groove. The outer surface of the end of the limiting block away from the sliding plate is set with an incline, and the incline of the sliding plate slides in contact with the inner wall of the limiting groove.

[0010] Preferably, the ends of the two first scrapers that are far apart from each other are in close contact with the inner wall of the pouring opening.

[0011] Preferably, a connecting plate is slidably connected inside the support frame, and a threaded rod is rotatably connected to the upper end of the connecting plate via a rotating shaft. The threaded rod extends from the end away from the connecting plate to the outer side of the top of the support frame, and the upper end of the second scraper is fixedly connected to the bottom end of the connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model involves placing high-load permeable concrete into the inside of a concrete storage tank through the inlet, then starting a motor to drive the drive gear to rotate. The rotation of the drive gear meshes with the driven gear, causing the shaft to rotate and driving the mixing blades to stir the concrete inside the storage tank, preventing internal solidification. Then, by rotating the threaded rod, the thread of the threaded rod passes through the top of the support frame, pushing the connecting plate to move the second scraper. The height of the second scraper is adjusted, so that the second scraper can be used for leveling different concrete pouring thicknesses.

[0014] 2. This utility model pushes the movable rod downwards along the inside of the through hole. At this time, the inclined surface of the limiting block slides into contact with the limiting groove at the bottom of the movable rod, thereby pushing the sliding plate along the inner wall of the movable groove to compress the spring. This causes the limiting block to disengage from the limiting groove at the bottom of the movable rod. When the movable rod moves and drives the first scraper to extend into the inside of the pouring opening, the limiting groove near the upper end of the movable rod corresponds to the movable groove. At this time, the limiting block, under the elastic push of the spring, inserts into the limiting groove, thereby fixing the position of the movable rod. Then, by rotating the shaft, the movable rod can be driven to rotate, and the first scrapers on both sides of the bottom end of the movable rod will come into contact with the inner wall of the pouring opening, thereby scraping off the concrete adhering to the inner wall of the pouring opening, avoiding clogging the pouring opening and affecting the subsequent concrete pouring.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figure 1As shown, one embodiment of this utility model provides a high load-bearing permeable concrete pouring device, including a base 1 and a concrete storage tank 3. A support seat 2 is fixedly provided at the upper end of the base 1, and the concrete storage tank 3 is located inside the upper end of the support seat 2. A feed inlet 4 is provided on one side of the upper end of the concrete storage tank 3. A pouring port 17 extending through to the bottom end of the concrete storage tank 3 is fixedly connected to the bottom end of the base 1. A shaft 5 is rotatably connected inside the concrete storage tank 3. Several stirring blades 11 are connected to the outer surface of the shaft 5. A first scraper 13 is connected to both sides of the bottom end of the shaft 5 through a connecting rod 12. A support frame 18 is provided at the upper end of the base 1 and on one side of the support seat 2. A second scraper 21 extending through to the bottom end of the base 1 is movably provided inside the support frame 18.

[0022] As a preferred technical solution in this embodiment, such as Figure 3 As shown, the top end of the shaft 5 extends through to the outer side of the top of the concrete storage tank 3. A driven gear 6 is fixedly connected to the outer surface of the shaft 5 at one end of the concrete storage tank 3. A fixed frame 7 is fixedly provided on one side of the driven gear 6 and at the top of the concrete storage tank 3. The bottom end of the fixed frame 7 is connected to the driving gear 9 through the motor 8, and the outer surface of the driving gear 9 meshes with the outer surface of the driven gear 6.

[0023] In this embodiment, high load-bearing permeable concrete is placed inside the concrete storage tank 3 through the inlet 4. Then, the motor 8 is started to drive the drive gear 9 to rotate. The drive gear 9 rotates and meshes with the driven gear 6, causing the shaft 5 to start rotating. This drives the stirring blade 11 to stir the concrete inside the concrete storage tank 3, preventing it from solidifying inside.

[0024] As a preferred technical solution in this embodiment, such as Figure 1 and Figure 2 As shown, a connecting plate 19 is slidably connected inside the support frame 18. The upper end of the connecting plate 19 is rotatably connected to a threaded rod 20 via a rotating shaft. The threaded rod 20 extends from the end away from the connecting plate 19 to the outer side of the top of the support frame 18. The upper end of the second scraper 21 is fixedly connected to the bottom end of the connecting plate 19. By rotating the threaded rod 20, the threaded rod 20 passes through the top of the support frame 18, pushing the connecting plate 19 to move the second scraper 21, thereby adjusting the height of the second scraper 21. This allows the second scraper 21 to be suitable for leveling different concrete pouring thicknesses.

[0025] As a preferred technical solution in this embodiment, such as Figure 2 and Figure 4As shown, a through hole 501 is vertically opened inside the shaft 5. Symmetrical movable grooves 502 are opened on both sides of the through hole 501 and inside the shaft 5 near the bottom. Sliding plates 14 are slidably connected inside the movable grooves 502 on both sides. A spring 15 is fixedly connected between the side of the two sliding plates 14 that is far apart from each other and the inner wall of the movable groove 502. A limiting block 16 is fixedly connected to the side of the two sliding plates 14 that is close to each other. The end of the limiting block 16 that is far away from the sliding plate 14 extends movably through into the through hole 501. A movable rod 10 is slidably connected inside the through hole 501. Symmetrical limiting grooves 1001 are opened on the upper and lower sides of the movable rod 10 near the bottom. The end of the limiting block 16 that extends through into the through hole 501 is inserted into the corresponding limiting groove 1001. The outer surface of the end of the limiting block 16 that is far away from the sliding plate 14 is set with an incline. The incline of the sliding plate 14 slides in contact with the inner wall of the limiting groove 1001.

[0026] In this embodiment, by pushing the movable rod 10 downward along the interior of the through hole 501, the inclined surface of the limiting block 16 slides into contact with the limiting groove 1001 at the bottom of the movable rod 10, thereby pushing the sliding plate 14 to compress the spring 15 along the inner wall of the movable groove 502, causing the limiting block 16 to disengage from the limiting groove 1001 at the bottom of the movable rod 10. When the movable rod 10 moves and drives the first scraper 13 to extend into the interior of the pouring port 17, the movable rod 10 approaches the upper limiting groove 1001 and the movable groove 502. Corresponding to 2, at this time, the limiting block 16 is inserted into the limiting groove 1001 under the elastic push of the spring 15, thereby fixing the position of the movable rod 10. The ends of the two second scrapers that are far apart from each other are in contact with the inner wall of the pouring port 17. By rotating the shaft 5, the movable rod 10 can be driven to rotate, and the first scrapers 13 on both sides of the bottom end of the movable rod 10 will scrape off the concrete adhering to the inner wall of the pouring port 17 by contacting the inner wall of the pouring port 17, so as to avoid blocking the pouring port 17 and affecting the subsequent pouring of concrete.

[0027] Working principle: When using the high load-bearing permeable concrete pouring device, the high load-bearing permeable concrete is placed inside the concrete storage tank 3 through the inlet 4. Then, the motor 8 is started to drive the drive gear 9 to rotate. The drive gear 9 rotates and meshes with the driven gear 6, causing the shaft 5 to start rotating. This drives the mixing blade 11 to mix the concrete inside the concrete storage tank 3, preventing internal solidification. Then, by rotating the threaded rod 20, the thread of the threaded rod 20 passes through the top of the support frame 18, and pushes the connecting plate 19 to move the second scraper 21. The height of the second scraper 21 is adjusted, so that the second scraper 21 can be used for leveling different concrete pouring thicknesses.

[0028] After the concrete storage tank 3 is used, the movable rod 10 is pushed down along the inside of the through hole 501. At this time, the inclined surface of the limiting block 16 slides into contact with the limiting groove 1001 at the bottom of the movable rod 10, thereby pushing the sliding plate 14 along the inner wall of the movable groove 502 to compress the spring 15, causing the limiting block 16 to disengage from the limiting groove 1001 at the bottom of the movable rod 10. When the movable rod 10 moves and drives the first scraper 13 to extend into the inside of the pouring port 17, the movable rod 10... The upper limit groove 1001 corresponds to the movable groove 502. At this time, the limit block 16 is pushed by the spring 15 and inserted into the limit groove 1001, thereby fixing the position of the movable rod 10. Then, by rotating the shaft 5, the movable rod 10 can be driven to rotate, and the first scraper 13 on both sides of the bottom end of the movable rod 10 will come into contact with the inner wall of the pouring port 17, thereby scraping off the concrete adhering to the inner wall of the pouring port 17, so as to avoid blocking the pouring port 17 and affecting the subsequent concrete pouring.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
