Description

Technical Field

[0001] This utility model relates to the field of sand and gravel screening, and in particular to a leap screen. Background Technology

[0002] In fields such as sand and gravel aggregate processing, mining, and construction waste resource utilization, screening equipment serves as the core equipment for material grading, and its performance directly affects the gradation quality and production efficiency of the final product. The leaping screen, with its unique reciprocating motion characteristics, enables the material on the screen surface to undergo a regular "leaping" motion, thereby achieving efficient grading.

[0003] Among them, the material blocking device, as a key component for controlling the trajectory of material movement, directly determines the uniformity of material distribution on the screen surface, residence time, and final screening efficiency through its rational structural design. However, existing material blocking devices generally adopt a fixed structural design, lacking both angle adjustment function and flexible adjustment in the length direction. This rigid structure severely restricts the equipment's adaptability to different working conditions.

[0004] In actual production, sand and gravel materials of different particle sizes and with different moisture levels have drastically different requirements for the feed rate: fine sand requires a slower feed rate to ensure thorough screening, while coarse sand requires a faster feed rate to increase throughput. Fixed feed racks, because their parameters cannot be adjusted, cannot optimize the feed rate according to material characteristics, and are difficult to cope with changes in material characteristics during production. This leads to problems such as low screening efficiency and unstable product quality, severely restricting the overall operating efficiency of the production line. Utility Model Content

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] This utility model provides, for example Figure 1-5 The illustrated leap screen includes: a leap screen body 1, used for screening sand and gravel; and adjustable baffle devices 2, installed on both sides of the screen mesh of the leap screen body 1, with the adjustable baffle devices 2 arranged in a staggered manner. Each adjustable baffle device 2 includes: a rotating mechanism 21, installed on the leap screen body 1; and a telescopic mechanism 22, which is angularly adjustable relative to the rotating mechanism 21 and can also be extended or retracted in length. The telescopic mechanism 22 is used to block sand and gravel on the screen mesh. The staggered arrangement of the adjustable baffle devices 2 facilitates the operation of the leap screen. The main body 1 blocks the sand and gravel on the screen. The rotating mechanism 21 facilitates the adjustment of the angle of the telescopic mechanism 22 relative to the screen of the main body 1 of the leaping screen. In conjunction with the adjustment of the overall length of the telescopic mechanism 22, the leaping speed of the sand and gravel can be adaptively adjusted. Through the coordinated operation of the rotating mechanism 21 and the telescopic mechanism 22, the dual adjustment function of the angle and length of the adjustable material blocking device 2 is realized. This dual adjustment mechanism can control the leaping speed and movement trajectory of the material according to the particle size and moisture characteristics of the material, thereby improving the screening efficiency. In particular, for wet materials with a moisture content of more than 5%, the blocking angle can be appropriately increased and the blocking length can be shortened to effectively prevent material accumulation.

[0045] Furthermore, the rotating mechanism 21 includes: an ear plate 211, which is fixedly mounted on the main body 1 of the leaping screen; and an angle locking assembly 212, which is inserted into the ear plate 211 and is used to position the relative angle between the ear plate 211 and the telescopic mechanism 22. The angle locking assembly 212 includes: a fixing ring 2121, which is fixedly mounted on the ear plate 211; an elastic member, which is inserted into the ear plate 211; and a snap-fit ​​member, which is connected to the end of the elastic member and is used to lock the relative position between the ear plate 211 and the telescopic mechanism 22. The elastic element includes: a pressing block 2122, which is movably disposed inside the fixing ring 2121; a connecting rod 2123, one end of which is fixedly connected to the pressing block 2122; and a spring 2124, which is movably sleeved outside the connecting rod 2123. Through the compression deformation of the spring 2124, the pressing block 2122 is elastically supported. Under the connection of the connecting rod 2123, the sliding plate 2125 tends to move towards the pressing block 2122, making the fit between the positioning post 2126 and the slot more stable. The snap-fit ​​component includes: a sliding plate 2125, which is movably disposed inside the telescopic mechanism 22; and a positioning post 2126, one end of which is fixedly connected to the sliding plate 2125, and the positioning post 2126 is movably engaged with the telescopic mechanism 22. The bottom of the ear plate 211 has multiple slots arranged in a circular array. The positioning post 2126 engages with the inner cavity of the slots. Through the engagement between the positioning post 2126 and the slots, the positioning post 2126 is easily engaged between the ear plate 211 and the baffle 221, thereby achieving the desired angle adjustment of the baffle 221. The mechanism is fixed so that the position remains stable after the angle of the telescopic mechanism 22 is adjusted. When the angle of the telescopic mechanism 22 needs to be adjusted, the pressing block 2122 is pressed down, so that the pressing block 2122 moves towards the ear plate 211 under the limit of the fixing ring 2121. While compressing and deforming the spring 2124, it is easy to drive the sliding plate 2125 to move through the connection of the connecting rod 2123, so that the positioning post 2126 is disengaged from the inner cavity of the slot, thereby realizing the angle locking between the contact ear plate 211 and the baffle 221.

[0046] The telescopic mechanism 22 includes: a baffle 221, one end of which is rotatably connected to an ear plate 211 via a bearing; the baffle 221 has an internal cavity for the lifting and lowering movement of the slide plate 2125; a connecting rod 2123 is rotatably connected to the ear plate 211 via a bearing; a telescopic rod 222, which is slidably sleeved with the baffle 221; and a slide bar 223, which is fixedly installed on the side of the telescopic rod 222. The inner side of the baffle 221 has a groove that cooperates with the slide bar 223. The cooperation between the slide bar 223 and the groove facilitates the limiting of the sliding of the telescopic rod 222 relative to the baffle 221, making the telescopic adjustment of the telescopic rod 222 relative to the baffle 221 more stable. The sliding cooperation between the telescopic rod 222 and the inner cavity of the baffle 221 facilitates the adjustment of the overall length of the telescopic mechanism 22.

[0047] The telescopic mechanism 22 further includes a positioning component 224, which is installed on the top of the other end of the baffle 221 and is used to position the relative position between the baffle 221 and the telescopic rod 222. The positioning component 224 includes a nut seat 2241, which is fixedly installed on the baffle 221; a bolt rod 2242, which is threadedly engaged with the nut seat 2241; and a positioning block 2243, which is connected to one end of the bolt rod 2242. Multiple positioning grooves are linearly formed on the telescopic rod 222, and the positioning block 2243 engages with the inner cavity of the positioning grooves. Through the threaded engagement between the bolt rod 2242 and the nut seat 2241, the position of the positioning block 2243 can be adjusted so that it fits into the positioning groove, thereby achieving the positioning of the relative position between the baffle 221 and the telescopic rod 222.

[0048] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
