Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and in particular to a stone waste crushing device. Background Technology

[0002] Stone crushers are machines that use methods such as squeezing, splitting, bending, impacting, and rolling to break large rocks into smaller pieces. Commonly used crushers include jaw crushers, cone crushers, hammer crushers, and roller crushers. During stone mining and processing, in order to process the cut-off materials together, it is necessary to crush stones of different sizes to facilitate their subsequent use.

[0003] After crushing, stone can be used for other purposes, such as construction. However, the crushing process easily produces stones and gravel of varying sizes. These gravel particles tend to adhere to each other, and if the crushed stone residue is not screened, the finished product will contain gravel of different particle sizes, resulting in uneven particle size distribution. For example, when used as construction aggregate, excessively large particles will affect the compaction of concrete, while excessively small particles will reduce strength. When used as asphalt recycling materials, particle size deviations will disrupt the gradation design of the mixture and affect the durability of the pavement. Therefore, a stone residue crushing device is proposed to solve the above problems. Utility Model Content

[0023] like Figure 1-3 As shown, the present invention proposes a stone waste crushing device, including a frame 1, a feed hopper 11, two guide plates 12 and two crushing rollers 13. The feed hopper 11 is connected to the top of the frame 1, the two guide plates 12 are connected to the top wall of the frame 1, and the two crushing rollers 13 rotate relative to each other inside the frame 1. It also includes a collection hopper 2, a dispersing cylinder 3 and a screen plate 4. The collection hopper 2 is installed below the two crushing rollers 13 and its bottom end is connected to a discharge pipe 21. The dispersing cylinder 3 is hinged to the outside of the bottom end of the discharge pipe 21. The screen plate 4 is inclinedly arranged below the dispersing cylinder 3. The screen holes on the front and rear sides of the screen plate 4 are progressively larger. The frame 1 is provided with a drive mechanism that drives the dispersing cylinder 3 to swing left and right continuously.

[0024] In this invention, the feed hopper 11 is connected to the top of the frame 1, and two guide plates 12 are arranged opposite each other in a V-shape to concentrate the stones to be crushed between the two crushing rollers 13 for easy crushing. The two crushing rollers 13 are driven by a motor and two meshing gears. The crushed stones are collected by the collection hopper 2, which is completely attached to the inner wall of the frame 1. The material falls into the bulk material cylinder 3 along the discharge pipe 21. The bulk material cylinder 3 is continuously oscillated left and right by the drive mechanism. While oscillating, the material is evenly scattered on the screen plate 4 to prevent the stones from being concentrated in the middle of the screen plate 4 during screening, thus improving the screening effect. By setting the screen plate 4 to be two-stage, it has a multi-stage screening effect, classifying the stones produced during crushing and then conveying them separately to improve the recycling effect.

[0025] In an optional embodiment, a support frame 8 is connected to the front side of the frame 1, and an installation port is provided on the front side of the frame 1. The sieve plate 4 is disposed on the support frame 8 and extends into the frame 1 through the installation port.

[0026] It should be noted that when the two crushing rollers 13 rotate, they will cause vibration. The bottom end of the screen plate 4 is equipped with a limit rod and a spring, which will cause the screen plate 4 to vibrate up and down continuously.

[0027] In an optional embodiment, both the bottom end of the frame 1 and the support frame 8 are provided with discharge ports, and the two are connected to each other. Conveyors 5 are provided under both the support frame 8 and the frame 1.

[0028] It should be noted that the screened-out crushed stones fall onto the two conveyors 5 through the discharge port.

[0029] In an optional embodiment, a fixing frame 6 is connected to the rear side of the frame 1, and the fixing frame 6 is L-shaped.

[0030] In an optional embodiment, the drive mechanism includes a motor 71, a first rotating rod 72, a turntable 73, a rotating shaft 74, two second rotating rods 75, and a swing frame 76. The two second rotating rods 75 are respectively connected to the front and rear sides of the bulk material cylinder 3, and their opposite sides are respectively rotatably connected to the front wall of the frame 1 and the fixed frame 6. The motor 71 is located on the rear side of the fixed frame 6. One end of the first rotating rod 72 is coaxially connected to the output shaft of the motor 71. The turntable 73 is connected to the front end of the first rotating rod 72. The rotating shaft 74 is rotatably connected to the front edge of the turntable 73. The swing frame 76 is connected to the rear second rotating rod 75 and is located on the rear side of the turntable 73.

[0031] In an optional embodiment, the swing frame 76 is provided with a sliding groove, and the rotating shaft 74 is slidably connected to the inner wall of the sliding groove.

[0032] It should be noted that when the bulk material cylinder 3 is driven to swing left and right, the starting motor 71 drives the first rotating rod 72 to rotate, which in turn drives the turntable 73 to rotate. At this time, the rotating shaft 74 continuously slides on the inner wall of the sliding groove, driving the swing frame 76 to drive the second rotating rod 75 to rotate left and right, which in turn drives the bulk material cylinder 3 to swing continuously.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
