Abstract
Description
Technical Field
[0001] This utility model relates to stone screening, specifically a stone screening device. Background Technology
[0002] When processing crushed stone, it is necessary to separate large and small pieces, which requires a crushed stone screening device. Currently, crushed stone screening involves manually collecting small and large pieces after screening. Since large pieces are heavy, it is very inconvenient to manually clean them in the screening frame with a bucket or broom. Utility Model Content
[0003] To address the shortcomings of the existing technology, this invention provides a crushed stone screening device that can automatically collect small pieces of crushed stone as well as large pieces of stone, eliminating the need for manual cleaning.
[0004] To achieve the above technical objectives, this utility model adopts the following technical solution: a crushed stone screening device, including a receiving bucket, a screening frame, and a shaking rod; the screening frame is equipped with filter plates that can be combined or opened to output large stones; a column is fixed inside the receiving bucket, a bearing plate is fixed at the top of the column, a guide column is fixed on the bearing plate, a guide sleeve is fitted on the guide column, the guide sleeve is connected to the side of the screening frame, the shaking rod passes through the middle of the bearing plate, the upper end of the shaking rod is fixed to the bottom center of the screening frame, the lower end of the shaking rod passes through the bearing plate and contacts a cam, the cam is connected to a motor; the surface of the bearing plate is inclined to guide the crushed stones falling from the screening frame into the receiving bucket, and the bottom of the receiving bucket is inclined for material discharge.
[0005] The receiving bucket is funnel-shaped, the column is fixed to the inclined wall, and the outside of the receiving bucket is also provided with mounting plates for fixing the receiving bucket.
[0006] The size of the support plate is smaller than the size of the receiving bucket.
[0007] The support plate is also provided with a protective cover, which is fitted onto the shaking rod, and the outer wall of the protective cover is inclined.
[0008] The motor is fixed to the bottom of the support plate and is also covered by an outer cover to cover the motor, the cam, and the vibration rod located below the support plate.
[0009] A central plate is provided at the center of the screening frame, and a connecting rod is provided between the central plate and the screening frame. The connecting rod divides the screening frame into at least two areas, and a filter plate is installed in each area. A hinge is provided between the filter plate and the connecting rod. An installation ring is provided on the inner wall of the screening frame, and the filter plate is detachably connected to the installation ring. The shaking rod is fixed to the bottom of the central plate.
[0010] In summary, this utility model achieves the following technical effects:
[0011] This invention combines a funnel-shaped receiving bucket and a screening frame. The screening frame is positioned above the receiving bucket, and the gravel screened by the screening frame falls into the receiving bucket below and is then discharged through the receiving bucket. The support plate is designed with an incline to send the gravel falling on it to the receiving bucket below. The screening frame can open the filter plate to allow large stones to be discharged from the receiving bucket. It is convenient to use and does not require manual collection.

[0020] Example:
[0021] Figure 1 This is a crushed stone screening device, including a receiving bucket 9, a screening frame 1, and a shaking rod 4. The screening frame 1 is equipped with filter plates 105 that can be combined or opened to output large stones. A column 12 is fixed inside the receiving bucket 9, and a bearing plate 7 is fixed to the top of the column 12. A guide column 3 is fixed to the bearing plate 7, and a guide sleeve 2 is fitted to the guide column 3. The guide sleeve 2 is connected to the side of the screening frame 1. The shaking rod 4 passes through the middle of the bearing plate 7. The upper end of the shaking rod 4 is fixed to the bottom center of the screening frame 1, and the lower end of the shaking rod 4 passes through the bearing plate 7 and contacts a cam 6. The cam 6 is connected to a motor 5. The surface of the bearing plate 7 is inclined to guide the crushed stones falling from the screening frame 1 into the receiving bucket 9. The bottom of the receiving bucket 9 is an inclined wall 10 for material discharge.
[0022] This invention combines a funnel-shaped receiving bucket and a screening frame. The screening frame is positioned above the receiving bucket, and the gravel screened by the screening frame falls into the receiving bucket below and is then discharged through the receiving bucket. The support plate is designed with an incline to send the gravel falling on it to the receiving bucket below. The screening frame can open the filter plate to allow large stones to be discharged from the receiving bucket. It is convenient to use and does not require manual collection.
[0023] The receiving bucket 9 is funnel-shaped, the column 12 is fixed to the inclined wall 10, and the outside of the receiving bucket 9 is also provided with an mounting plate 11 for fixing the receiving bucket 9.
[0024] This invention fixes the receiving bucket on the frame (not shown), with the upper screening box for receiving materials and the lower discharge port for discharging materials, eliminating the need for manual collection and making it convenient to use.
[0025] The size of the bearing plate 7 is smaller than that of the receiving bucket 9, so as to catch the gravel falling from the bearing plate.
[0026] The support plate 7 serves as a connector between the receiving bucket and the screening frame, as well as a motor mounting component, and also provides a buffer for the crushed stone.
[0027] The support plate 7 is also provided with a protective cover 8, which is sleeved on the shaking rod 4, and the outer wall of the protective cover 8 is inclined.
[0028] Because the crushing site is very dusty, installing a protective cover can prevent crushed stone from entering the gap between the vibrating rod and the bearing plate, thus preventing increased friction. The crushed stone falls outward along the outer wall and will not enter the gap.
[0029] The motor 5 is fixed to the bottom of the support plate 7, and is also covered by an outer cover 13 to cover the motor 5, the cam 6, and the shaking rod 4 located below the support plate 7.
[0030] Figure 2 This is a schematic diagram of a screening frame. A center plate 101 is provided at the center of the screening frame 1. A connecting rod 102 is provided between the center plate 101 and the screening frame 1. The connecting rod 102 divides the screening frame 1 into at least two areas. Each area is equipped with a filter plate 105 (filter holes are not shown in the figure). A hinge 106 is provided between the filter plate 105 and the connecting rod 102. An installation ring 103 is provided on the inner wall of the screening frame 1. The filter plate 105 and the installation ring 103 are detachably connected. The shaking rod 4 is fixed to the bottom of the center plate 101.
[0031] This utility model features a connecting rod 102 that connects the screening frame and the internal center plate, and also serves as a hinge point for the filter plate, facilitating its opening or closing. When closed, the filter plate can be used as a filter plate, while when opened, it allows large stones to fall into the receiving bucket, making it easier to collect large stones. This replaces the current method of cleaning and collecting with a shovel or broom, eliminating the need for manual collection, making it convenient to use, and saving labor.
[0032] The filter plate 105 and the mounting ring 103 are connected by bolts 104, which facilitates installation and disassembly.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
