[0001] The utility model relates to the technical field of side wall extrusion, in particular to a side wall extruder. Background Art
[0002] The extrusion side wall slope protection technology is a new technology for the slope construction of panel dam cushion materials, which was created by drawing on the extrusion sliding formwork principle of the roadside machine in road gardening projects. This technology uses the principle of continuous pressure displacement to continuously form concrete side walls with a trapezoidal cross-section during construction. It has the characteristics of ensuring the compaction quality of the cushion materials, improving the slope protection capability and facilitating construction. It has become a new technology for panel dam construction. It is also widely used in concrete slope protection of highway and railway filling projects, anti-slip concrete retaining walls around buildings and mountains, and concrete face protection of flood control embankments of rivers and lakes.

[0027] In the prior art, concrete is allowed to enter a molding bin and is extruded through the molding bin to form a concrete retaining wall. However, the concrete is poured into the feed hopper of the extruder by an excavator or manually. However, due to the large size of the feed hopper, the existing feeding method is not convenient for evenly spreading the concrete in the feed hopper, and thus it is not convenient for the concrete to evenly enter the molding bin. If the concrete in the molding bin is uneven, the density of the wall concrete will be uneven. Some parts may be too loose, while other parts may be too tight, which will affect the overall strength and stability of the wall and reduce its quality. Secondly, the concrete in the feed hopper is also easy to adhere to the inside of the feed hopper, resulting in a waste of concrete resources. Therefore, after research, a side wall extruder is provided. When in use, the lower hopper is moved left and right in the first slide rail so that the concrete can evenly pass through the lower hopper into the feed box. At the same time, the cylinder is combined to move the first slide rail up and down, so that the lower hopper moves up and down according to the feeding height, ensuring the uniformity of the concrete, which is conducive to the concrete evenly and fully entering the molding box, thereby solving the above defects.
[0028] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0029] Please refer to Figure 1-Figure 5 The embodiment of the utility model provides a side wall extruder, including a machine body 1, a feed box 2 is arranged on one side of the machine body 1, a molding box 3 is arranged on one side of the feed box 2, and the feed box 2 is used to receive concrete.
[0030] In order to allow the concrete to enter the feed box 2 evenly, slide grooves 11 are symmetrically opened on both sides of the body 1 located at the upper end of the feed box 2, and the second slide rails 7 are slidably connected in the symmetrical slide grooves 11. The lower hopper 6 is slidably connected between the two second slide rails 7. The lower hopper 6 slides left and right in the second slide rails 7, so that the concrete enters the feed box 2 evenly from the discharge port opened on the lower side of the lower hopper 6. The size of the discharge port on the lower side of the lower hopper 6 is adapted to the width of the feed box 2.
[0031] Among them, screw rods 71 are rotatably arranged in the two second slide rails 7, and the two screw rods 71 are respectively threadedly connected to the sliders 69 arranged on both sides of the lower hopper 6. The sliders 69 are slidably arranged in the second slide rails 7, and the two screw rods 71 are connected by a transmission member 72. The transmission member 72 is a pair of pulleys respectively connected to the two screw rods 71, and belts are sleeved on the two pulleys. One of the pulleys is driven by a motor, and the two screw rods 71 are rotated through the operation of the transmission member 72, thereby ensuring the stable movement of the lower hopper 6.
[0032] Furthermore, a symmetrical limit plate 4 is provided on the machine body 1 at the upper end of the feed box 2 . The limit plate 4 is located on the upper side of the lower hopper 6 to limit the height of the lower hopper 6 moving up and down.
[0033] In order to make the lower hopper 6 move up and down, a cylinder 5 is installed at the upper end of the limit plate 4. The piston end of the cylinder 5 is connected to the upper side of the second slide rail 7. When the cylinder 5 moves up and down with the second slide rail 7, the lower hopper 6 is prompted to move up and down in the feed box 2. The position of the lower hopper 6 can be adjusted according to the height of the concrete loaded in the feed box 2 to prevent concrete splashing.
[0034] Secondly, in order to prevent the concrete from adhering to the inner wall of the lower hopper 6, first slide rails 61 are provided on both sides of the lower hopper 6, and moving rods 63 are slidably connected in the two first slide rails 61. A connecting rod 66 is provided between the two moving rods 63, and push plates 67 are provided on the lower sides of both ends of the connecting rod 66. Since the push plates 67 are in contact with the inner wall of the lower hopper 6, when the connecting rod 66 is pushed, the push plates 67 are prompted to clean the inner wall of the lower hopper 6 to discharge the concrete.
[0035] In addition, scrapers 68 are provided on both sides of the pusher plate 67, and the scrapers 68 can scrape the stubborn concrete.
[0036] It is worth noting that a protrusion 64 is provided on the lower side of the moving rod 63 , and the protrusion 64 is slidably connected to the limiting groove 62 opened on the upper side of the first slide rail 61 , which can improve the stability of the moving rod 63 when moving.
[0037] At the same time, in order to facilitate the reset of the moving rod 63, a spring 65 is provided at one end of the first slide rail 61, one end of the spring 65 is connected to one side of the moving rod 63, the spring 65 is squeezed when the moving rod 63 slides, and when the spring 65 loses its force, the moving rod 63 is reset.
[0038] Taking into account the possibility of concrete splashing when the lower hopper 6 moves out of the feed box 2, a card slot 12 is opened on both sides of the feed box 2, and a side panel 13 is snapped into the card slot 12 to shield the concrete. At the same time, the side panel 13 is installed by snapping, which is convenient for disassembly and cleaning.
[0039] The side plates 13 are symmetrically provided with striker bars 14 which are threadedly connected to the side plates 13 . When the lower hopper 6 moves to the striker bars 14 , the striker bars 14 strike against the lower hopper 6 , causing the lower hopper 6 to vibrate, thereby promoting the discharge of concrete.
[0040] In summary, the working principle of the side wall extruder of the embodiment of the utility model is: pour concrete into the lower hopper 6, and the lower hopper 6 is lowered into the feed box 2 by the cylinder 5, and the lower hopper 6 is moved left and right by the rotation of the screw 71, so that the concrete enters the feed box 2 evenly, and the position of the lower hopper 6 is adjusted according to the height of the concrete in the feed box 2, and the lower hopper 6 will collide with the impact rod 14 when it moves, and the lower hopper 6 will generate vibration to accelerate the discharge of materials, and secondly, the connecting rod 66 is pushed to make the push plate 67 clean the inner wall of the lower hopper 6.
[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
