Description
Technical Field
[0001] The utility model belongs to the technical field of vibrating screens, and particularly relates to a civil engineering vibrating screen. Background Art
[0002] Civil engineering vibrating screens are mainly applied to civil engineering projects. For example, in operations such as concrete mixing and masonry, screening of sand and gravel is required, which can effectively remove impurities and unqualified particles in the sand and gravel and ensure the construction quality.
[0003] During civil engineering projects, raw materials are poured into the hopper. After the raw materials reach the screen on the surface of the support, the vibration motor is started, and the vibration motor drives the screen to vibrate. During the vibration of the screen, the raw materials are screened. When there is a large amount of raw materials entering the hopper, a large number of raw materials reach the screen at the same time, which will cause some raw materials to leave the screen without being screened, resulting in a reduction in the screening effect of the raw materials. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a civil engineering vibrating screen, which is used to solve the technical problem that when there is a large amount of raw materials entering the hopper, a large number of raw materials reach the screen at the same time, which will cause some raw materials to leave the screen without being screened, and then the screening effect of the raw materials is reduced.
[0005] The utility model is realized by adopting the following technical scheme:
[0006] A civil engineering vibrating screen includes a support, and also includes an installation component. A vibration motor is arranged on one side of the support, a screen is arranged on the upper side of the support, the screen is obliquely arranged, a feed hopper is arranged at the top of the screen on the support, and a regulating device is arranged on one side of the feed hopper through the installation component. The regulating device includes a placement rack, one side of the placement rack is fixedly connected with an electric telescopic rod, the output end of the electric telescopic rod is fixedly connected with a push plate, one side of the push plate is fixedly connected with a regulating plate, and the size of the regulating plate is adapted to the size of the feed hopper.
[0007] During application, raw materials are poured into the hopper, and then the raw materials reach the screen on the surface of the support. Then the vibration motor is started to vibrate the vibrating support for screening of the raw materials. When reducing the amount of raw materials entering the hopper, the electric telescopic rod can be started to drive the push plate to move, and then the push plate drives the regulating plate to block the feed. The regulating plate will block a part of the area at the entrance of the feed hopper, completing the reduction of the size of the entrance of the feed hopper, so as to realize the reduction of the amount of raw materials entering the hopper. By using the regulating device, the amount of raw materials entering the hopper can be adjusted and controlled, avoiding the situation that a large number of raw materials reach the screen at the same time, resulting in some raw materials leaving the screen without being screened, thereby improving the use effect of the vibrating screen.
[0008] Further preferably, two reinforcing plates are fixedly connected between the output end of the electric telescopic rod and the push plate to further strengthen the strength of the connection between the output end of the electric telescopic rod and the push plate.
[0009] Further preferably, the placement rack includes a vertical plate and a horizontal plate. The vertical plate and the horizontal plate are combined into an L shape. One side of the vertical plate is fixedly connected with a stabilizing plate. The stabilizing plate passes through the push plate and is slidably connected with the push plate. The length of the stabilizing plate is greater than the length after the electric telescopic rod extends. By using the stabilizing plate, the stability of the push plate during movement is improved, so that the regulating plate can move more stably.
[0010] Further preferably, a rubber ring is fixedly connected to one side of the electric telescopic rod close to the output end. The diameter size of the rubber ring is adapted to the diameter size of the electric telescopic rod. By using the rubber ring, the output end of the electric telescopic rod is sealed to prevent small sundries in some raw materials from reaching the inside of the electric telescopic rod through the gap at the output end of the electric telescopic rod.
[0011] Further preferably, baffles are fixedly connected to both sides of the regulating plate. The size in the length direction of the baffles is adapted to the size of the regulating plate. By using the baffles, both sides of the regulating plate are blocked to prevent some raw materials from detaching from both ends of the regulating plate after reaching the upper end of the regulating plate, thereby improving the use effect of the regulating plate.
[0012] Further preferably, the installation assembly includes an installation block. The installation block is fixedly connected to the feed hopper. The installation block is provided with a through hole penetrating up and down. A connecting plate is inserted into the through hole. The top of the connecting plate is fixedly connected to the placement rack. A first threaded hole is provided on one side of the installation block, and a second threaded hole is provided on the connecting plate. The first threaded hole and the second threaded hole are connected by a bolt. When using the regulating device, by moving the connecting plate at the bottom of the placement rack, the connecting plate is inserted into the installation block, and then the bolt is rotated so that the bolt passes through the installation block and reaches the inside of the connecting plate, and then the position of the regulating device is fixed. By using the installation assembly, the position of the regulating device can be quickly fixed, so that it is convenient for the operator to use the regulating device subsequently.
[0013] Further preferably, a trapezoidal block is fixedly connected to the bottom of the connecting plate. The size of the trapezoidal block on the side away from the connecting plate is smaller than that on the other side. By using the trapezoidal block, the size of one side of the connecting plate is reduced, so that the connecting plate can be more easily inserted into the installation block.
[0014] Further preferably, a number of uniformly distributed anti-slip blocks are fixedly connected to the head of the bolt. By using the anti-slip blocks, the friction between the bolt and the operator is increased, so that the operator can more easily rotate the bolt.
[0015] The utility model has the following beneficial effects:
[0016] By using the regulating device, the amount of raw materials entering the inside of the feed hopper can be adjusted, avoiding the situation that a large amount of raw materials reach the screen at the same time, resulting in some raw materials leaving the screen without being screened, thereby improving the use effect of the vibrating screen.
