Technical Field
[0001] The utility model relates to the technical field of construction sand screening device, in particular to a construction site sand screening device which is convenient for transportation and assembly. Background Art
[0002] Sand screener is a common sand screening equipment. Its working principle is: the screen is moved by vibration, rotation or swinging to disperse and move the mixture on the screen. Due to the large size of sand particles, they cannot pass through the pores of the screen, while other smaller impurities can pass through the screen, thereby achieving the purpose of separating sand and impurities. The separated sand will slide to the discharge port at the bottom and be collected or discharged. In general, sand screener is an efficient and practical sand screening equipment that can effectively separate sand from other impurities and meet the sand particle size requirements of different industries.
[0003] Sand screeners are usually used at construction sites. They are important equipment to ensure project quality and improve work efficiency at construction sites. Therefore, when selecting and using sand screeners, it is necessary to fully consider the specific needs and conditions of the construction site to ensure that they can perform at their best.
[0004] At present, when using the sand screener, it is usually necessary to install the sand screener on site, and then power on the sand screener, and finally put the sand on the filter screen of the sand screen, so as to remove the impurities in the sand through the vibration of the filter screen.
[0005] However, when using the sand screener, the existing sand screener is large in size and difficult to store, thus requiring a large storage space, which is not conducive to its transportation, increases transportation costs, and affects the flexibility of the construction plan. Utility Model Content
[0006] Based on this, the purpose of the utility model is to provide a construction site sand screener that is easy to transport and assemble, so as to solve the technical problem that the sand screener is large in size and difficult to store, thus requiring a large storage space, which is not conducive to transporting it, increases transportation costs, and affects the flexibility of the construction plan.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a construction site sand screen that is easy to transport and assemble, comprising a connecting plate, a second bottom plate fixedly connected to the bottom of the connecting plate, a card slot is provided in the connecting plate, and a card block matching the card slot is slidably connected in the card slot, a movable plate is rotatably connected to one side of the card block, a first bottom plate is provided at the bottom of the movable plate, and the movable plate and the first bottom plate are connected by a group of springs, a group of limit grooves are provided on one side of the connecting plate, and a limit block matching the limit groove is slidably connected in the limit groove, the limit block is fixedly connected to one side of the movable plate, and the limit block is arranged as a "T"-shaped structure.
[0008] By adopting the above technical scheme, through the setting of the card block and the card slot, the card block can be driven to move upward in the card slot until the limit block slides out of the limit slot. At this time, the movable plate is rotated to drive the card block to move downward in the card slot, so that the first bottom plate is flush with the second bottom plate, and then the position of the first bottom plate and the second bottom plate is fixed, and the sand screen is assembled, which is convenient for screening sand at the construction site. At the same time, the card block can slide upward in the card slot until the card block moves to the top of the card slot, driving the movable plate to rotate on one side of the card block, so that the movable plate is parallel to the connecting plate, and then the movable plate is driven downward by the card block, so that the limit block slides in the limit slot, and the position of the movable plate can be fixed by the limit block and the limit slot, thereby completing the storage of the device and reducing its storage space, which can reduce transportation costs and improve the flexibility of construction plans.
[0009] The utility model is further configured such that the connecting plate is fixedly connected to a silencer box, and a motor is placed in the silencer box, the output end of the motor is connected to one end of a rotating shaft, and the other end of the rotating shaft movably passes through one side of the silencer box and the outer surface of the connecting plate and extends to the outside to be connected to an eccentric wheel, and the eccentric wheel is located at the bottom of the movable plate.
[0010] By adopting the above technical solution and setting the motor and the rotating shaft, the motor can drive the rotating shaft and the eccentric wheel to rotate synchronously, so that the eccentric wheel continuously generates an upward force on the movable plate, thereby causing the movable plate to move upward. At the same time, when the movable plate moves upward, it will generate a pulling force on the spring, and after the upward force generated by the eccentric wheel on the movable plate disappears, the spring drives the movable plate to reset. Repeating this movement can cause the movable plate to vibrate, thereby facilitating better screening of sand.
[0011] The utility model is further configured that a groove is provided on one side of the movable plate, and the bottom of the groove is configured as a filter structure.
[0012] By adopting the above technical solution and setting the groove, sand can be placed in the groove and then screened by the vibration of the movable plate, which can prevent sand from falling from both sides of the movable plate and affecting the screening of the sand.
[0013] The utility model is further configured that a group of thread grooves are arranged on one side of the connecting plate, and bolts matching the thread grooves are threadedly connected in the thread grooves, and one end of the bolts is rotatably connected to one side of the clamping block.
[0014] By adopting the above technical solution, through the arrangement of the threaded groove and the bolt, after the slider reaches the specified position, the bolt can be turned to squeeze the block, so that the position of the block can be fixed, thereby preventing the block from sliding in the groove due to external force when screening the sand, thereby affecting the screening of the sand.
[0015] The utility model is further configured such that mounting holes are provided at four corners of the first bottom plate and the second bottom plate.
[0016] By adopting the above technical solution and setting the mounting holes, fixing parts such as expansion bolts can be set in the mounting holes, so that the positions of the first base plate and the second base plate can be fixed, thereby fixing the position of the device, which is convenient for better screening of sand.
[0017] The utility model is further configured that one side of the groove is configured as a slope structure.
[0018] By adopting the above technical solution and setting the inclined structure, it is beneficial for the impurities screened out of the groove when the movable plate screens the sand, so as to avoid affecting the subsequent screening of the sand.
[0019] In summary, the utility model mainly has the following beneficial effects:
[0020] The utility model can make the card block slide upward in the card slot through the arrangement of the card block and the card slot, and can drive the movable plate to rotate on one side of the card block until the card block moves to the top of the card slot, so that the movable plate is parallel to the connecting plate, and then the movable plate is driven downward by the card block to make the limit block slide in the limit slot, so that the position of the movable plate can be fixed by the limit block and the limit slot, so that the storage of the device can be completed, the storage space of the sand screener can be reduced, the transportation of the sand screener can be facilitated, the transportation cost can be reduced, and the flexibility of the construction plan can be improved.
