Description

Technical Field

[0001] This utility model relates to the field of concrete pole preparation technology, specifically to a rapid concrete feeding device. Background Technology

[0002] Concrete poles are poles made of concrete and reinforcing bars or wires. Most of them refer to ring-shaped concrete poles. The manufacturing process mainly involves longitudinally tensioning the wire skeleton in a steel mold, and then squeezing out excess water from the concrete under centrifugal force, thereby greatly increasing the density and strength of the concrete.

[0003] In existing concrete pole production, most methods involve creating a pouring hole above the pole mold and pouring concrete into the mold at a fixed point. This results in uneven concrete distribution and slow flow within the forming groove, leading to low pouring efficiency. To address these issues, utility model publication CN220297446U discloses an environmentally friendly feeding device for concrete pole production (hereinafter referred to as Prior Art 1). This device includes a pole mold with a forming groove inside and a pouring groove in the center of its top surface. Sliding grooves are located on both the front and rear sides of the top surface of the pole mold, and sliding blocks are connected inside these grooves. An electric push rod is mounted on the top of the sliding block, and a fixing plate is connected to the top of the electric push rod. A feeding mixing tank is connected to the inner side of the fixing plate, and a material hopper is connected to the bottom of the feeding mixing tank. A discharge pipe is installed at the bottom of the material hopper.

[0004] Although the feeding equipment in the prior art 1 can move and pour concrete into the pole mold, making the concrete more evenly distributed in the forming trough, when the feeding equipment in the prior art 1 feeds the concrete into the forming trough, the gaps between the steel bars in the steel cage are too small, which causes the concrete to not fully enter the steel cage, resulting in insufficient grouting. This affects the grouting effect and efficiency, and at the same time, it is necessary to clean the concrete residue remaining on the surface of the pole mold. Utility Model Content

[0005] The purpose of this utility model is to provide a rapid concrete feeding device, which can solve the problem in the prior art where the concrete discharged from the feeding device cannot fully enter the steel cage due to the small gaps between the steel bars in the steel cage, thus affecting the grouting effect and grouting efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A rapid concrete feeding device includes a movable base and a material box installed on the movable base. The bottom end of the material box is provided with a discharge port, and two rotating plates are hinged on the material box for opening or closing the discharge port.

[0008] The material box is detachably connected to a mounting frame, and two scraping assemblies are symmetrically installed on the mounting frame. The scraping assembly includes a scraper and a guide plate fixedly connected to the scraper. The scraper is used to scrape off the residual material on the pole mold, and the guide plate is used to guide the residual material into the steel cage located in the pole mold.

[0009] The hopper is equipped with a drive device for opening and closing the rotating plate.

[0010] Preferably, a baffle plate is detachably connected to the rotating plate.

[0011] Preferably, the baffle plate is hinged to the rotating end of the rotating plate.

[0012] Preferably, a vibrator is installed on the material box.

[0013] Preferably, a slide rail is installed under the material box, and the slide rail is used to slide on the pole mold.

[0014] Preferably, a rotating shaft is rotatably mounted inside the slide rail.

[0015] Preferably, an air pump is installed on the material box, and an air nozzle for cleaning the pole mold is installed on the mounting frame. An air supply pipe is installed on the air pump, and the air nozzle is connected to the air supply pipe.

[0016] Preferably, the air nozzle is located on the side of the scraper away from the hopper.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this embodiment, the material box is slidably mounted on the pole mold via the movable seat. After the movable seat is driven to move along the direction of the pole mold, the concrete in the material box can move into the reinforcing cage to inject concrete, so that the concrete is distributed more evenly in the reinforcing cage, thereby further improving the pouring efficiency.

[0019] The pole mold is positioned between two scraping assemblies. The bottom end of the scraper contacts the pole mold. As the moving seat drives the scraping assembly to move, the scraper can scrape away the concrete material remaining on the surface of the pole mold.

[0020] The guide plate is inclined toward the reinforcing cage, and the concrete material is guided into the reinforcing cage under the guidance of the guide plate. This not only avoids wasting concrete material, but also cleans the concrete material on the surface of the pole mold, further improving the feeding efficiency and avoiding the waste of manpower.

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] See Figures 1-3This embodiment discloses a feeding device for injecting concrete into a steel cage 114 placed in the pole mold 115. Specifically, it is a rapid feeding device, including a movable seat and a material box 101 installed on the movable seat. The bottom end of the material box 101 is provided with a discharge port, and two rotating plates 102 are hinged on the material box 101 for opening or closing the discharge port.

[0035] A mounting frame 103 is detachably connected to the material box 101. Two scraping assemblies 104 are symmetrically installed on the mounting frame 103. Each scraping assembly 104 includes a scraper 105 and a guide plate 106 fixedly connected to the scraper 105. The scraper 105 is used to scrape off the residual material on the pole mold 115, and the guide plate 106 is used to guide the residual material into the steel cage 114 located in the pole mold 115.

[0036] The material bin 101 is equipped with a drive device 107 for driving the rotating plate 102 to open and close.

[0037] In this embodiment, when concrete needs to be injected into the reinforcing cage 114 placed in the pole mold 115, the driving device 107 first drives the rotating plates 102, which are symmetrically hinged at both ends of the material box 101 outlet, to rotate simultaneously away from the center line of the material box 101 to open the outlet. The material box 101 is slidably mounted on the pole mold 115 via the movable seat. After the movable seat is driven to move along the direction of the pole mold 115, the concrete in the material box 101 can move into the reinforcing cage 114 to inject concrete, making the concrete more evenly distributed in the reinforcing cage 114, further improving the pouring efficiency. In this embodiment, the driving device 107 is a conventional telescopic rod mechanism in the prior art. The fixed end and telescopic end of the telescopic rod mechanism are respectively hinged to two rotating plates 102. When the telescopic rod mechanism extends, the rotating plates 102... When the telescopic rod mechanism is retracted, the rotating plate 102 closes. A small portion of the concrete material in the material box 101 will splash onto the pole mold 115 after colliding with the reinforcing cage 114 during the discharge process through the discharge port. The pole mold 115 is located between two scraping components 104, and the bottom end of the scraper 105 contacts the pole mold 115. During the movement of the scraping components 104 driven by the moving seat, the scraper 105 can scrape off the concrete material remaining on the surface of the pole mold 115. The guide plate 106 is inclined towards the reinforcing cage 114, and the concrete material is guided into the reinforcing cage 114 under the guidance of the guide plate 106. This avoids waste of concrete material and also cleans the concrete material on the surface of the pole mold 115, further improving the feeding efficiency and avoiding the waste of manpower.

[0038] In some embodiments, a baffle plate 108 is detachably connected to the rotating plate 102. The baffle plate 108 is used to guide the concrete raw material discharged from the outlet into the pole mold 115, and the baffle plate 108 is arranged perpendicular to the surface of the pole mold 115.

[0039] In some embodiments, the baffle plate 108 is hinged to the rotating end of the rotating plate 102. Driven by the driving device 107, the baffle plate 108 can change its opening and closing angle according to the actual width of the pole mold 115. By hinged to the rotating end of the rotating plate 102, the baffle plate 108 can adjust its angle as needed, allowing it to be perpendicular to the surface of the pole mold 115 for better material blocking effect.

[0040] In some embodiments, a vibrator 109 is installed on the hopper 101. By setting the vibrator 109, it is possible to prevent the concrete raw materials in the hopper 101 from getting blocked at the discharge port during the feeding process.

[0041] In some embodiments, a slide rail 110 is installed under the material bin 101, and the slide rail 110 is used to slide on the pole mold 115. After the material bin 101 is slidably mounted on the pole mold 115 via the slide rail 110, the material bin 101 can be guided and limited.

[0042] In some embodiments, a rotating shaft 111 is rotatably mounted inside the slide rail 110. By setting the rotating shaft 111, the sliding friction between the slide rail 110 and the pole mold 115 can be converted into rolling friction, thus preventing the material box 101 from scratching the pole mold 115 during movement.

[0043] In some embodiments, an air pump is installed on the material bin 101, and an air nozzle 112 for cleaning the pole mold 115 is installed on the mounting bracket 103. An air supply pipe 113 is installed on the air pump, and the air nozzle 112 is connected to the air nozzle 112 through the air supply pipe 113. After the scraper 105 removes the residue remaining on the pole mold 115, the air pump draws gas into the air supply pipe, which then delivers it to the air nozzle 112 and sprays it out to clean the surface of the pole mold 115, preventing any residual material from remaining on the surface of the pole mold 115 and affecting subsequent mold closing and centrifugation.

[0044] In some embodiments, the air nozzle 112 is disposed on the side of the scraper 105 away from the material box 101. By disposing the scraper 105 between the air nozzle 112 and the material box 101, it can be ensured that after the scraper 105 scrapes off the residual material during the movement of the material box 101, the air nozzle 112 cleans the pole mold 115, further reducing the waste of concrete raw materials.

[0045] In some embodiments, the material bin 101 is equipped with a stirring device. The stirring device is used to stir the concrete raw materials in the material bin 101 to prevent the raw materials in the material bin 101 from separating. In this embodiment, the concrete raw materials are conventional stirring mechanisms in the prior art, and their structure and function will not be described in detail here.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
