Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric pole production equipment, in particular to a raw material mixing device used for electric pole production. Background Art
[0002] Cement poles are important supporting structures for power transmission and communication lines. The raw material mixing and pouring process in their production process plays a vital role. During the production process, the mixed cement raw materials need to be evenly poured into the pole bottom mold equipped with the pole steel cage. After the pouring is completed, the pole bottom mold and the pole top mold need to be closed, and then the overall mold is sent to the centrifugal equipment for centrifugal treatment to form the cement pole.
[0003] Usually, the pouring process mainly relies on the operator's experience and skills to control, including the pouring rate and pouring amount. This reliance on human factors often makes it difficult to ensure the uniformity of pouring, and the cement may be partially too thick or too thin in the mold.
[0004] After pouring is completed, cement often piles up in the mold in the over-poured area. The excessively poured cement will protrude from the bottom mold of the pole, hindering the closing of the bottom mold and the top mold of the pole, requiring additional manpower to remove it. At the same time, the removed cement is often difficult to recycle and reuse, resulting in a waste of resources. Summary of the invention
[0005] The utility model aims to solve the problems existing in the prior art and provides a raw material mixing device for producing electric poles.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A raw material mixing device for producing electric poles, comprising a mixing device arranged at a mold conveying track, the mixing device comprising a support frame and a mixing tank, the mixing tank being arranged on the support frame, the mixing tank comprising a tank body, a stirring assembly and a recovery device, the tank body being provided with a stirring assembly, the recovery device being located on one side of the tank body, the recovery device comprising a scraper hopper, a storage box and a screw conveyor, the scraper hopper being arranged on the feeding side of the storage box, the screw conveyor being arranged on the storage box, the feeding port at the bottom of the screw conveyor being located in the storage box, and the discharging port at the top of the screw conveyor being connected to the tank body through a pipeline.
[0008] The utility model pours the electric pole reinforcement cage after fully stirring the raw materials in the tank body by arranging the stirring component. During the pouring process, the electric pole reinforcement cage can be filled with cement through excessive pouring. The excess cement after pouring can be scraped and collected in the storage box in time through the recovery device. Through the conveying action of the screw conveyor, the recovered cement can be returned to the tank body for reuse.
[0009] Preferably, the mold conveying track is arranged through the support frame, a conveying vehicle is provided on the mold conveying track, the conveying vehicle moves along the mold conveying track through the support frame, a pole bottom mold is provided on the conveying vehicle, and a pole steel cage is provided in the pole bottom mold.
[0010] Through the combination of the mold conveying track and the support frame, the mixing device can be seamlessly connected to the production line to achieve automated production. The setting of the conveying vehicle allows the pole bottom mold and the pole steel cage to easily enter and exit the mixing device, thereby improving production efficiency.
[0011] Preferably, a discharge pipe is provided at the bottom of the tank body, baffles are provided on both sides of the discharge pipe, the baffles are arranged parallel to the mold conveying track, and the spacing between adjacent baffles is not less than the diameter of the electric pole reinforcement cage.
[0012] The design of the discharge pipe enables the mixed cement raw materials to flow smoothly into the pole bottom mold, and the setting of the baffle prevents the cement raw materials from overflowing. By adjusting the spacing of the baffles, it can be ensured that the cement raw materials flow accurately into the pole bottom mold, avoiding waste and pollution of cement raw materials.

[0014] The height design of the scraper hopper ensures that it can effectively scrape away excess cement attached to the pole steel cage, and the design of the arc-shaped scraper makes the scraping process more closely fit the surface of the pole steel cage, thereby improving the scraping efficiency. This design not only reduces the tediousness and time-consuming manual shoveling, but also avoids the damage and waste that may be caused by manual shoveling.
[0015] Preferably, when the electric pole reinforcement cage moves to below the scraper hopper, the top of the scraper is arranged in contact with the surface of the electric pole reinforcement cage, the end of the scraper is connected to the storage box, and the end of the scraper is higher than the top of the scraper.
[0016] When the electric pole reinforcement cage moves to under the scraper hopper, the scraper can fit closely to its surface, thereby effectively scraping off excess cement. The end of the scraper is higher than the top of the scraper, leaving sufficient height for installing the storage box and the screw conveyor, thereby avoiding collision between the storage box and the screw conveyor and the moving electric pole reinforcement cage.
[0017] Preferably, the material storage box comprises a bottom plate, the bottom plate is higher than the top end of the scraper, and a sealing plate is provided between the end of the scraper and the bottom plate.
[0018] Since the scraper is an arc-shaped plate, there is a large gap between it and the bottom plate, and the sealing plate needs to be used for sealing to prevent the recovered cement raw materials from leaking from the gap.
[0019] Preferably, the bottom of the screw conveyor is arranged on the bottom plate, the screw conveyor passes through the top of the storage box, and the discharge port of the screw conveyor is higher than the top of the tank body.

[0022] The provision of the feeding door facilitates the addition of raw materials into the tank body, and the design of the stirring assembly enables the raw materials to be fully and evenly stirred in the tank body.
[0023] Compared with the prior art, the beneficial effects of the utility model are:
[0024] (1) The utility model provides a stirring assembly to fully stir the raw materials in the tank body, and then pours the electric pole reinforcement cage. During the pouring process, cement is poured in excess so that the electric pole reinforcement cage can be filled. The excess cement after pouring can be scraped and collected in the storage box in time through the recovery device. Through the conveying action of the screw conveyor, the recovered cement can be returned to the tank body for reuse.
[0025] (2) The utility model combines the mold conveying track with the support frame, so that the mixing device can be seamlessly connected to the production line to realize automated production.

[0032] like Figures 1 to 3 As shown, the specific scheme of the embodiment is as follows: Embodiment 1: This embodiment 1 is mainly used in the automated assembly line for producing cement poles. By integrating key links such as raw material mixing and pouring, efficient and precise production of cement poles is achieved. On the automated assembly line, the raw material mixing device and the mold conveying system are seamlessly connected, ensuring the timely supply of raw materials and smooth transportation of molds.
[0033] A raw material mixing device for producing electric poles, including a mixing device arranged at a mold conveying track 1, the mixing device including a support frame 2 and a mixing tank, the mixing tank is arranged on the support frame 2, the mold conveying track 1 is arranged through the support frame 2, a conveying vehicle 101 is arranged on the mold conveying track 1, the conveying vehicle 101 moves along the mold conveying track 1 through the support frame 2, an electric pole bottom mold 102 is arranged on the conveying vehicle 101, and an electric pole reinforcement cage 103 is arranged inside the electric pole bottom mold 102.
[0034] The mixing tank includes a tank body 3, a stirring assembly 4 and a recovery device. The tank body 3 is provided with a stirring assembly 4, and a feeding door is provided at the top of the tank body 3. The stirring assembly 4 includes a stirring motor, a stirring rod and a stirring paddle. The stirring motor is arranged at the top of the tank body 3, and the stirring motor is connected to the stirring rod through a reducer, and the stirring paddle is arranged around the stirring rod.
[0035] A discharge pipe is provided at the bottom of the tank body 3 , and the raw materials in the tank body 3 are poured into the electric pole reinforcement cage 103 through the discharge pipe after being mixed and stirred by the stirring paddle.
[0036] The recovery device is located on one side of the tank body 3. The recovery device is arranged directly above the route of the electric pole reinforcement cage 103. The recovery device includes a scraper hopper 5, a storage box 6 and a screw conveyor 7. The scraper hopper 5 and the storage box 6 are arranged in parallel. The storage box 6 is a box body with a single side open. The open side of the storage box 6 is the feed side. The scraper hopper 5 is arranged on the feed side of the storage box 6, and the screw conveyor 7 is arranged on the storage box 6.
[0037] The scraper hopper 5 is a box body with two open sides. The discharge port of the scraper hopper 5 is connected to the storage box 6. The feed port of the scraper hopper 5 is arranged on the side away from the storage box 6. The height of the scraper hopper 5 is not lower than the height of the pole steel cage 103 to avoid collision between the scraper hopper 5 and the moving pole steel cage 103.
[0038] The scraper hopper 5 includes a scraper 501 arranged at the bottom. The scraper 501 is an arc-shaped plate. The curvature of the scraper 501 is adapted to the curvature of the surface of the pole steel cage 103. When the pole steel cage 103 moves below the scraper hopper 5, the top of the scraper 501 is set in contact with the surface of the pole steel cage 103.
[0039] The storage box 6 includes a bottom plate 601, and the end of the scraper 501 is connected to the bottom plate 601 of the storage box 6. The end of the scraper 501 is higher than the top of the scraper 501. Since there is a gap between the arc area below the scraper 501 and the flat bottom plate 601, a sealing plate is provided between the end of the scraper 501 and the bottom plate 601 to seal the gap between the scraper 501 and the bottom plate 601 to prevent the recovered cement from leaking from the arc area below the scraper 501.
[0040] The bottom plate 601 is higher than the top of the scraper 501, so that there is enough space between the storage box 6 and the electric pole reinforcement cage 103, which is convenient for the installation of the screw conveyor 7. The screw conveyor 7 is connected to the support frame 2 through a connecting rod.
[0041] The bottom of the screw conveyor 7 is set on the bottom plate 601, the screw conveyor 7 passes through the top of the storage box 6, the discharge port of the screw conveyor 7 is higher than the top of the tank body 3, the feed port at the bottom of the screw conveyor 7 is located in the storage box 6, and the discharge port at the top of the screw conveyor 7 is connected to the tank body 3 through a pipeline.
[0042] The working method of the first embodiment is as follows: the raw materials are put into the tank body 3 of the mixing tank, and the stirring assembly 4 is used to fully mix and stir them. When the conveying vehicle 101 carries the pole bottom mold 102 equipped with the pole steel cage 103 and moves along the mold conveying track 1 to the mixing device, the conveying vehicle 101 first passes through the discharge pipe and then passes through the recovery device.
[0043] When the mixing device is working, the mixed cement raw materials flow out through the discharge pipe and enter the pole bottom mold 102. The flow rate of the discharge pipe is constant. Through excessive pouring, the cement raw materials can fill the pole bottom mold 102. During this process, the conveying vehicle 101 moves slowly. When passing through the recovery device, the excess cement raw materials protruding from the pole bottom mold 102 are scraped off by the scraper 501 that fits tightly to the surface of the pole steel cage 103, completing the cleaning of the surface of the pole steel cage 103, so that after the pole steel cage 103 is poured, the pole top mold and the pole bottom mold 102 can be smoothly closed, and the conveying vehicle 101 sends the closed pole mold to the centrifuge for the molding process.
[0044] When the recovery device is working continuously, cement raw materials are continuously scraped into the scraper hopper 5 by the scraper 501, so that the cement raw materials that first enter the scraper hopper 5 are continuously pushed until they fall into the storage box 6. The cement raw materials that fall into the storage box 6 will gradually fill up the storage box 6. During this process, the cement raw materials will enter the screw conveyor 7 and return to the tank body 3 through the screw conveyor 7 to re-participate in the mixing and pouring process.
[0045] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is that:
[0046] A material blocking structure 8 is provided at the discharge pipe, and the material blocking structure 8 includes a baffle and a connecting plate. The baffles are located on both sides of the discharge pipe, and the baffles are arranged parallel to the mold conveying track 1. The baffles are connected by connecting plates, and the connecting plates are arranged on the discharge pipe. The spacing between adjacent baffles is not less than the diameter of the pole steel cage 103. When the pole steel cage 103 moves, it needs to pass between the baffles.
[0047] When the mixing device is working, the mixed cement raw material flows out through the discharge pipe. Due to the guiding effect of the baffle, the raw material flows into the pole bottom mold 102 accurately.
[0048] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
