Description

Technical Field

[0001] This invention relates to the field of concrete production technology, specifically to a concrete block forming device. Background Technology

[0002] Concrete refers to a general term for engineering composite materials in which aggregates are bound together by cementing materials. After physical processing, concrete acquires excellent mechanical properties, which are widely used in civil and industrial construction. One of the most important applications is through concrete blocks. Concrete blocks on the market generally include ordinary concrete small hollow blocks, lightweight aggregate concrete small hollow blocks, autoclaved aerated concrete blocks, and foamed concrete blocks. Concrete blocks have advantages such as high strength, light weight, convenient construction, good wall surface flatness, and high construction efficiency. The research focus of concrete block manufacturing machinery is to efficiently prepare concrete blocks from concrete slurry, achieve good formability, and process irregularly shaped blocks to meet the requirements of building construction.

[0003] In the process of forming large concrete blocks, large molds are generally used for casting. Due to the increased volume, unlike the forming of small concrete blocks, the limited material feeding range clashes with the larger load-bearing volume, which leads to the need to solve the problem of uniform pouring during the casting process. Existing methods mostly involve manual scraping and moving the concrete repeatedly with tools during the pouring process to ensure that the concrete is evenly filled into the mold for subsequent static forming. At the same time, in order to avoid excessive accumulation and overflow of concrete at the feeding point, the concrete feeding rate is controlled, which is time-consuming and laborious and affects the overall concrete block forming rate. In view of this, we propose a concrete block forming device. Summary of the Invention

A limiting arm is fixedly connected to the surface of the meshing gear. A slide is elastically connected to the interior of the limiting arm via a spring. A cleaning gear is rotatably connected to the interior of the slide. A cleaning brush roller is fixedly connected to the end of the cleaning gear away from the slide. A fixed toothed seat meshes with the surface of the meshing gear, and an arc-shaped side toothed plate meshes with the surface of the cleaning gear.

[0007] Preferably, the surface of the slide block is slidably connected to the inner wall of the limiting arm, the surface of the fixed toothed seat is fixedly connected to the surface of the fixed base, and the surface of the arc-shaped side toothed plate is fixedly connected to the surface of the pressing base.

[0008] Preferably, the inner wall of the arc-shaped scraper seat is fixedly connected to the surface of the lower pressure base, a rubber scraper is fixedly connected to the surface of the arc-shaped scraper seat, and a feeding cavity is opened between the arc-shaped scraper seat and the rubber scraper. A pressure shaft is fixedly connected to the side of the limiting arm near the lower pressure base. The guiding feeding device includes a triangular prism and a limiting plate. The surface of the triangular prism is elastically connected to the surface of the lower pressure base by a spring, and a guide plate is fixedly connected to the surface of the triangular prism.

[0009] Preferably, the surface of the limiting plate is fixedly connected to the surface of the pressing base, and the bottom of the triangular prism is slidably connected to the top of the limiting plate.

[0010] Preferably, a telescopic guide rod is fixedly connected to the top of the fixed base, the bottom end of the telescopic guide rod is fixedly connected to the top of the pressing base, a concrete discharge pipe is fixedly connected to the top of the fixed base, and the surface of the I-shaped pressing plate is slidably connected to the inner wall of the pressing base.

[0011] Preferably, the material feeding and positioning device further includes a movable support plate and a fixed support plate, the surface of the movable support plate is slidably connected to the interior of the material feeding base, and a pressure roller is rotatably connected to the interior of the movable support plate.

[0012] Preferably, the surface of the movable support plate is elastically connected to the surface of the feeding base via a spring, the bottom of the fixed support plate is fixedly connected to the surface of the feeding base, and the surface of the pressure roller is movably connected to the surface of the toothed pressure rod.

[0013] Preferably, the top end of the toothed pressure rod is fixedly connected to the top of the lower pressure base, the surface of the toothed pressure rod is provided with teeth, and the surface of the rotating feeding frame seat is rotatably connected to the interior of the feeding base.

[0014] As can be seen from the above technical solutions, the concrete block forming device provided in the embodiments of this specification has at least the following beneficial effects:

[0015] (1) The present invention uses an electric push rod to press the upper and lower base to drive the I-shaped lower pressure plate to squeeze the concrete poured in the forming mold, and flatten the concrete piled up at the discharge point evenly to avoid the problem of concrete overflow. It can quickly and evenly lay the concrete and improve the efficiency of material feeding and forming. The layered flattening method can improve the effect and speed of concrete block forming and reduce the generation of air holes and gaps. The toothed pressure rod drives the rotating discharge frame seat on the rotating gear to rotate and make way. During the time of the movement, the discharge frame seat continues to receive the concrete discharged from the concrete discharge pipe and temporarily stores it. While flattening the concrete, the feeding is guaranteed, so as to achieve the effect of ensuring the feeding rate while flattening.

[0016] (2) The present invention drives the meshing gear to mesh with the fixed tooth seat by moving the lower pressure base, and drives the cleaning brush roller on the inner slide of the limit arm to rotate by the rotating connecting rod. Through the combination of the spring and the arc-shaped side tooth plate, the rotation trajectory of the cleaning brush roller is the same as the shape trajectory of the arc-shaped side tooth plate, thereby achieving the effect of long-term contact between the cleaning brush roller and the surface of the I-shaped lower pressure plate during rotation, scraping off the concrete material adhering to the surface of the lower pressure plate, achieving the effect of automatic cleaning of the surface of the lower pressure plate, thereby avoiding the problem of concrete adhering to the lower pressure plate.

[0017] (3) The present invention guides the concrete residue through the guide plate. When the pressure shaft on the limit arm makes intermittent pressing contact with the surface of the triangular column during rotation, it achieves the effect of pushing the triangular column, so that the triangular column drives the guide plate to move and make way on the limit plate, avoiding the problem that the concrete material adhering to it is scraped off in advance when the guide plate contacts it during the rotation of the cleaning brush roller.

Detailed Implementation

[0027] 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.

[0028] Please see Figures 1-7 As shown, the technical solution provided by this invention is as follows:

[0029] A concrete block forming device includes a fixed base 1. An electric push rod 2 is bolted to the top of the fixed base 1. The output shaft of the electric push rod 2 is fixedly connected to a lower pressure base 3. A scraper cleaning device 4 is provided on the surface of the lower pressure base 3. An I-shaped lower pressure plate 5 is elastically connected to the inside of the lower pressure base 3 via a spring. The surface of the I-shaped lower pressure plate 5 is slidably connected to the inner wall of the lower pressure base 3. A forming mold 6 and a feeding base 7 are fixedly connected to the bottom of the fixed base 1. The forming mold 6 is used to form blocks from poured concrete. A feeding clearance device 8 is provided inside the feeding base 7. A telescopic guide rod 9 is fixedly connected to the top of the fixed base 1. The telescopic guide rod 9 connects the fixed base 1 and the lower pressure base 3 while restricting the movement trajectory of the lower pressure base 3, allowing it to slide only in a straight line. The bottom end of the telescopic guide rod 9 is fixedly connected to... A concrete feeding pipe 10 is fixedly connected to the top of the lower pressure base 3 and the top of the fixed base 1. The concrete is fed into the forming mold 6 through the concrete feeding pipe 10 for forming. During the pouring process, the electric push rod 2 is activated to drive the I-shaped lower pressure plate 5 inside the lower pressure base 3 downward. The I-shaped lower pressure plate 5 contacts the concrete poured in the mold and squeezes it, flattening the concrete piled up at the feeding point evenly. This avoids the problem of concrete accumulation and improves the speed and uniformity of laying after pouring. The up-and-down squeezing method flattens the accumulated concrete evenly, avoiding the traditional reciprocating scraping and laying work, and improving the efficiency of uniform laying and forming. At the same time, the I-shaped lower pressure plate 5 continuously flattens the concrete intermittently during the pouring process. The layered flattening method improves the effect and speed of concrete block forming and reduces the generation of air holes and gaps.

[0030] The material feeding and yielding device 8 includes a rotating gear 81 and a toothed pressure rod 82. The end of the rotating gear 81 is rotatably connected to the end of the material feeding base 7. The rotating material feeding frame seat 83 is fixedly connected inside the rotating gear 81. The lower pressure base 3 drives the rotating material feeding frame seat 83 on the rotating gear 81 to rotate and yield through the toothed pressure rod 82. During the yielding period, the material feeding frame seat continues to receive the concrete fed from the concrete feeding pipe 10 and temporarily stores it. After the electric push rod 2 drives the lower pressure base 3 to reset, the material feeding frame seat pours the previously temporarily stored concrete material together with the new concrete material into the molding mold 6. While flattening the concrete, it ensures the feeding rate, achieving the effect of ensuring the feeding rate while flattening.

[0031] In this embodiment, the scraper cleaning device 4 includes a rotating connecting rod 41, a guide feeding device 49, and an arc-shaped scraper seat 410. One end of the rotating connecting rod 41 is rotatably connected to the interior of the pressing base 3, and the other end of the rotating connecting rod 41 is fixedly connected to a meshing gear 42. A limiting arm 43 is fixedly connected to the surface of the meshing gear 42. A slide 44 is elastically connected to the interior of the limiting arm 43 via a spring. The surface of the slide 44 is slidably connected to the inner wall of the limiting arm 43. A cleaning gear 45 is rotatably connected to the interior of the slide 44. A cleaning brush roller 46 is fixedly connected to the end of the cleaning gear 45 away from the slide 44. A fixed toothed seat 47 meshes with the surface of the meshing gear 42. The surface of the fixed toothed seat 47 is fixedly connected to the surface of the fixed base 1. The surface of the cleaning gear 45... The surface of the brush roller 46 is engaged with an arc-shaped side toothed plate 48, and the surface of the arc-shaped side toothed plate 48 is fixedly connected to the surface of the lower pressure base 3. When the brush roller 46 rotates around the pivot point of the rotating connecting rod 41, it is affected by the spring on the slide 44 and has an elastic pulling force. Combined with the influence of the cleaning gear 45 that is always in contact with the surface of the arc-shaped side toothed plate 48, the rotation trajectory of the brush roller 46 is the same as the shape trajectory of the arc-shaped side toothed plate 48. This achieves the effect of the brush roller 46 being in long-term contact with the surface of the I-shaped lower pressure plate 5 during rotation. During the contact, the rubber brush plate on the surface of the brush roller scrapes off the material adhering to the surface of the lower pressure plate due to the pressing of concrete, achieving the effect of automatic cleaning of the surface of the lower pressure plate, thereby avoiding the problem of concrete adhering to the lower pressure plate.

[0032] Furthermore, the inner wall of the arc-shaped scraper seat 410 is fixedly connected to the surface of the lower pressure base 3, and a rubber scraper 411 is fixedly connected to the surface of the arc-shaped scraper seat 410. A material discharge cavity is provided between the arc-shaped scraper seat 410 and the rubber scraper 411. When the rubber scraper 411 scrapes away concrete residue on the cleaning brush roller 46, the residue will be discharged through this cavity onto the guide plate 493. A pressure shaft 412 is fixedly connected to the side of the limiting arm 43 near the lower pressure base 3. The guiding and discharging device 49 includes a triangular prism 491 and a limiting plate 492. The surface of the triangular prism 491 is elastically connected to the surface of the lower pressure base 3 by a spring, and the guide plate 493 is fixedly connected to the surface of the triangular prism 491. The surface of the limiting plate 492 is fixedly connected to the surface of the lower pressure base 3. The bottom of the triangular prism 491 is slidably connected to the top of the limiting plate 492. During the rotation of the limiting arm 43 with the pivot point of the rotating connecting rod 41 as the center, the pressure shaft 412 presses against the surface of the triangular prism 491, causing the triangular prism 491 to drive the guide plate 493 to move and make way on the limiting plate 492. This avoids the problem of the guide plate 493 contacting the cleaning brush roller 46 during its rotation, which would cause the concrete material adhering to it to be scraped off prematurely. At the same time, the triangular prism 491 is affected by the spring force on it and can elastically reset after moving. After resetting, the guide plate 493 can achieve the function of receiving and guiding the material. The limiting plate 492 is used to support the movement of the triangular prism 491 while restricting its sliding trajectory, so that it can only slide laterally.

[0033] Furthermore, the material feeding and positioning device 8 also includes a movable support plate 84 and a fixed support plate 85. The surface of the movable support plate 84 is slidably connected to the interior of the material feeding base 7, and a pressure roller 86 is rotatably connected inside the movable support plate 84. The movable support plate 84 provides partial support for the rotating material feeding frame 83, and simultaneously performs a positioning movement using linkage, facilitating subsequent rotation and positioning of the rotating material feeding frame 83. The fixed support plate 85 provides bottom support for the rotating material feeding frame 83 after positioning, ensuring its stability at that angle. The surface of the movable support plate 84 is elastically connected to the surface of the feeding base 7 via a spring. The bottom of the fixed support plate 85 is fixedly connected to the surface of the feeding base 7. The surface of the pressure roller 86 is movably connected to the surface of the toothed pressure rod 82. The top of the toothed pressure rod 82 is fixedly connected to the top of the lower pressure base 3. The surface of the toothed pressure rod 82 is provided with teeth, which are distributed above the inclined surface of the toothed pressure rod 82. This achieves the effect that when the toothed pressure rod 82 moves downward, it first drives the movable support plate 84 to move through the inclined surface, and then drives the gear to rotate. The surface of the rotating feeding frame seat 83 is rotatably connected to the inside of the feeding base 7.

[0034] In use, the concrete block forming device of the present invention delivers concrete through the concrete discharge pipe 10 to the rotating discharge frame seat 83, and gradually pours it into the forming mold 6 for pouring due to the influence of its tilt angle. By activating the electric push rod 2, the output shaft of the electric push rod 2 drives the I-shaped lower pressure plate 5 elastically connected inside the lower pressure base 3. The I-shaped lower pressure plate 5 presses the concrete in the forming mold 6 downward, and the squeezing force flattens the concrete accumulated at the discharge point, thereby avoiding the problem of concrete accumulation and improving the rapid and uniform laying after pouring. The method of pressing the accumulated concrete flat and uniformly by the upper and lower squeezing method avoids the traditional reciprocating scraping and laying work, and improves the efficiency of uniform laying and forming.During the downward movement of the I-shaped lower pressure plate 5, the lower pressure base 3 moves via the toothed pressure rod 82 fixedly connected to it. As the toothed pressure rod 82 moves downward, it contacts the pressure roller 86 via its left inclined surface, causing the movable support plate 84 to move to the left. Before the movement, the movable support plate 84 provided bottom support for the rotating material feeding frame 83. After the movement, the support plate loses its supporting function, eliminating the rotational restriction on the material feeding frame. After the support plate moves down, the toothed pressure rod 82, through its teeth, drives the rotating material feeding frame 83 on the rotating gear 81 to rotate counterclockwise. The counterclockwise rotation of the frame allows the lower pressure base 3 to move down, continuing to receive concrete from the concrete feeding pipe 10 during this period and temporarily storing it. After the electric push rod 2 drives the lower pressure base 3 to move upward and reset, the previously stored concrete material is poured into the molding mold 6 along with the new concrete material. This ensures the feeding of concrete while it is being flattened, thus avoiding the problem of controlling the concrete feeding rate due to excessive accumulation and overflow at the feeding point, and improving the overall feeding and molding rate. After flattening the concrete, the I-shaped lower pressure plate 5 resets upward. During the upward reset, the rotating connecting rod 41 connected to it rotates through the meshing of the meshing gear 42 and the fixed gear seat 47, and drives the cleaning brush roller 46 in the slide 44 to rotate as a whole through the limiting arm 43. The cleaning brush roller 46 rotates around the pivot point of the rotating connecting rod 41 and is subjected to an elastic tension by the spring on the slide 44. The cleaning gear 45 on the cleaning brush roller 46 meshes and rotates on the arc-shaped side toothed plate 48. During the rotation of the rotating connecting rod 41, the cleaning brush roller 46 is affected by the arc-shaped side toothed plate 48 and the spring on the slide 44, causing its rotation trajectory to be the same as the shape trajectory of the arc-shaped side toothed plate 48. This achieves a long-term contact between the cleaning brush roller 46 and the surface of the I-shaped lower pressure plate 5 during rotation. During the contact, the rubber brush on the surface of the brush roller scrapes off the material adhering to the surface of the lower pressure plate due to the pressing of concrete, thereby avoiding the problem of concrete adhering to the lower pressure plate and improving the flatness of subsequent pressing work. After scraping, the cleaning brush roller 46 contacts the surface of the arc-shaped scraper seat 410 during subsequent rotation, and performs self-cleaning work after contacting the rubber scraper 411 on it. During the process, to prevent concrete residue from scattering randomly, a guide plate 493 guides the material flow. When the cleaning brush roller 46 rotates to the guide plate 493, the pressure shaft 412 on the limiting arm 43 presses against the surface of the triangular prism 491 as it rotates around the pivot point of the rotating connecting rod 41. This pressing action pushes the triangular prism 491, causing it to move and reposition the guide plate 493 on the limiting plate 492. This prevents the guide plate 493 from prematurely scraping off any adhering concrete material during the rotation of the cleaning brush roller 46. Prematurely scraped concrete, unaffected by the guide during the material flow, would fall randomly. The automatically repositioning guide plate 493 solves this problem.
