Description

Technical Field

[0001] The utility model relates to the field of colored stone metal tiles, in particular to a sand and gravel spreading device which is convenient for replacing filter plates. Background Art

[0002] Colored stone metal tiles, also known as stone granule metal tiles, are a new roofing material that combines the durability of metal tiles with the aesthetics of natural stone. They are made of galvanized steel sheets laminated with colored stone granules, an acrylic primer, and a varnish. The stone granules impart color and texture, while the acrylic coating provides weather resistance.

[0003] The prior art publication number is: CN211964871U, which discloses a sand and gravel spreading device for the production of colored stone metal tiles, including a support frame, a hopper and a discharge plate. The top of the support frame is fixedly connected to the left side of the hopper by soldering, and the back of the hopper is fixedly connected to a motor through the support plate. The output end of the motor is fixedly connected to a rotating rod through a coupling. The end of the rotating rod away from the motor passes through the hopper and extends to the inner cavity of the hopper. The end of the rotating rod extending to the inner cavity of the hopper is rotatably connected to the surface of the inner cavity of the hopper through a bearing; the sand and gravel spreading device for the production of colored stone metal tiles, when the discharge is blocked, the user can deal with the blockage in time, thereby ensuring the efficiency of sand and gravel spreading, saving the user's time, and to a certain extent increasing the overall service life. It is also convenient for the user to operate, can perform certain pretreatment on the raw materials, and can quickly replace the discharge plate.

[0004] With the above configuration, the prior art sand and gravel spreading device for producing colored stone metal tiles, by providing a rotating rod and a discharge plate, can, when a blockage occurs in the discharge, drive the drive plate to rotate by rotating the rotating rod to address the blockage. When the discharge plate fails and requires maintenance, it can be disassembled. However, the prior art sand and gravel spreading device for producing colored stone metal tiles has the following defects during operation:

[0005] In the prior art, a filter plate is installed inside the inner cavity of the hopper, and the raw materials need to be pre-processed through the filter plate first. At this time, some larger particles and some impurities will be filtered out by the filter plate. However, the raw materials that need to be processed are very large, which will cause more large particles and impurities to be filtered to the upper surface of the filter plate, and will accumulate on its surface, blocking the filter holes, making it impossible to filter the raw materials, and the filter plate cannot be replaced and cleaned, which is not conducive to the subsequent use of raw materials and reduces the production of colored stone metal tiles. Utility Model Content

[0006] The utility model is intended to provide a sand and gravel spreading device that is easy to replace the filter plate, mainly used to solve the technical problem in the prior art that the filter plate cannot be replaced, which easily causes the filter holes to be blocked by large particles and impurities, making it unfavorable for the use of raw materials.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A sand and gravel spreading device that is convenient for replacing filter plates comprises a hopper, a support leg is symmetrically fixed to one side of the hopper, and a fixed frame is symmetrically fixed to the other side of the hopper, one side of the upper end of the support leg is rotatably connected to a screw rod, one end of the screw rod is rotatably connected to one side of the upper end of the fixed frame, the other side of the upper end of the fixed frame is fixed to a motor for driving the screw rod, the outer wall of the screw rod is rotatably connected to a movable plate, the lower surface of the movable plate is symmetrically fixed to an electric telescopic rod, the end of the electric telescopic rod away from the movable plate is fixed to a magnet, a filter plate is placed inside the hopper, the upper surface of the filter plate is symmetrically fixed to iron blocks, and a collecting device is provided on the bottom surface of the fixed frame.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When the filter plate needs to be replaced, first turn on the motor so that the motor drives the screw to rotate, and the screw drives the movable plate to move, and place the movable plate directly above the filter plate. Then start the electric telescopic rod to make the electric telescopic rod approach the filter plate, and then align the dustproof groove with the iron block and insert it so that the magnet and the iron block are attracted. Then retract the electric telescopic rod and lift the filter plate out of the hopper. Then rotate the screw in the opposite direction so that the movable plate moves the filter plate directly above the collection box. Then pull out the filter plate and put it into the collection box to complete the operation.

[0011] 2.Beneficial effects:

[0012] The prior art solves the technical problem of dealing with blockage in the hopper by setting a rotating rod and a discharge plate. However, a filter plate is provided in the existing hopper. When the filter plate filters the raw materials, some large particles and impurities are filtered on the upper surface of the filter plate, which will form accumulations. The filter plate cannot be replaced, which will cause blockage in the filter holes and is not conducive to the filtering of the raw materials. The present solution solves the technical problem of the present invention by setting a supporting leg, a fixing frame, a screw rod, and a telescopic rod, so that the two ends of the screw rod are respectively rotatably connected to the supporting leg and the fixing frame, and then the movable plate is moved to the top of the filter plate by starting the motor, and then the electric telescopic rod is used to make the magnet attract the iron block on the filter plate and separate the filter plate from the hopper, and then the motor is started again to make the screw rod rotate in the opposite direction, and the filter plate is placed in the collection box, and then the filter plate can be replaced.

[0013] Preferably, the collection device includes a collection box having universal wheels fixed to the bottom surface of the collection box and a handle fixed to one side of the collection box, the outer surface of the handle being fixed with a non-slip rubber pad. The collection box can collect used filter plates and then push them out together through the handle and universal wheels, making it convenient to clean and maintain the filter plates.

[0014] Preferably, four electric telescopic rods are fixedly connected to the lower surface of the movable plate, and each of the electric telescopic rods corresponds to the iron block. This can make the filter plate more stable when being lifted, and can also make the magnet and the iron block attract each other, making the fixation better and more stable.

[0015] Preferably, a dustproof groove is provided at one end of the electric telescopic rod away from the movable plate, and a magnet is fixed at the bottom end of the inner wall of the dustproof groove, so that the magnet and the iron block are attracted to each other. The dustproof groove can effectively prevent particles and impurities from being attracted by the magnet and affecting the pulling of the filter plate.

[0016] Preferably, a junction box for driving the electric telescopic rod is fixedly connected to the upper surface of the movable plate. The electric telescopic rod can be conveniently driven through the junction box.

[0017] Preferably, there are two screw rods and two motors, and the motors drive the screw rods to rotate at the same speed, so that the moving plate moves faster and prevents the moving plate from not moving when the speeds are different.

[0018] Preferably, the fixing frame and the supporting legs are fixed to the hopper by screws, so that the fixing frame and the supporting legs are fixed more firmly. BRIEF DESCRIPTION OF THE DRAWINGS
