Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to a rapid stone screening and testing device. Background Technology

[0002] In water conservancy projects, concrete-faced rockfill dams are constructed by filling rockfill bodies with a wide range of particle sizes and extremely large differences in particle size. During construction, it is necessary to screen and test the stones to ensure the accuracy of stone mixing and thus ensure the overall compaction quality. In traditional construction processes, there is a lack of tools that can quickly test different stone particle sizes, resulting in low construction efficiency.

[0003] Chinese patent document CN 209715654 U describes a stone chip screening device, which has a relatively complex structure and high manufacturing cost; Chinese patent document CN 104138836 A describes a device for removing oversized stones from large-diameter soil, which also has the above problems and defects in use, and needs to be improved. Utility Model Content

[0004] This utility model provides a rapid stone screening and testing device, which solves the technical problems of inconvenient stone testing, low construction efficiency, and troublesome overall installation and dismantling of the device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a stone rapid screening and testing device, including multiple fixed frames arranged from top to bottom, the multiple fixed frames being detachably connected, a screen plate being arranged in the middle of the fixed frame, and multiple screen holes being evenly distributed on the screen plate, with the screen holes on different screen plates gradually decreasing in size along the direction from high to low.

[0006] In the preferred embodiment, two handles are symmetrically arranged on each side of the fixed frame.

[0007] In the preferred embodiment, ear plates are symmetrically arranged on both sides of the fixed frame, and two adjacent ear plates are connected by screws and nuts.

[0008] In the preferred embodiment, the outer side of the fixed frame is detachably provided with multiple alignment plates, which cooperate to form a space for positioning the fixed frame.

[0009] In a preferred embodiment, the outer side of the fixing frame is provided with a threaded hole, and fastening pins are inserted into the alignment plate and the threaded hole. The alignment plate is also provided with a round rod for gripping.

[0010] In a preferred embodiment, the sieve plate includes a plate body, with a third through hole on each side of the plate body, and a shaft passing through the third through hole and the fixing frame and extending outward.

[0011] In the preferred embodiment, the fixed frame has a first through hole and an arc-shaped hole on both sides, and the shafts on both sides pass through the first through hole and the arc-shaped hole respectively. The shafts are connected to the fixed frame by nuts.

[0012] In the preferred embodiment, the two sides of the plate are provided with rounded corners, and the external dimensions of the plate match the internal dimensions of the fixing frame.

[0013] In the preferred embodiment, two screws are symmetrically arranged on the side of the fixed frame that is closer to the arc-shaped hole. Multiple screws are connected by a drive plate, which has an inclined surface that is supported on the lower part of the shaft.

[0014] In a preferred embodiment, the drive plate includes a straight plate with multiple second through holes through it. A screw passes through the second through holes. Multiple triangular plates are vertically arranged on one side of the straight plate, with the inclined surface located on the outside of the triangular plates.

[0015] The beneficial effects of this utility model are as follows: by combining the fixed frame and the sieve plate to form a sieve layer, and assembling the sieve layers, the function of multiple sieves in the height direction can be realized at one time. The overall manufacturing is simple and the installation is convenient, ensuring quick use. At the same time, the position and tilt angle of the sieve plate can be adjusted as needed, so that stones of different particle sizes can be screened under their own weight, thus improving the efficiency of detection.

[0027] like Figures 1-5 In the present invention, a rapid stone screening and testing device includes multiple fixed frames 1 arranged from top to bottom, the multiple fixed frames 1 being detachably connected, a screen plate 2 being arranged in the middle of the fixed frame 1, the screen plate 2 having multiple screen holes evenly distributed on it, and the screen holes on different screen plates 2 gradually decreasing in size along the direction from high to low.

[0028] During construction, after the rockfill is compacted, the compacted material needs to be screened in pits to test the mixed composition of the stone, thereby ensuring the quality of compaction. This device can be used to screen the compacted rockfill and observe the proportion of each particle size. After the construction personnel assemble the device on site using the fixed frame 1 and the screen plate 2, they pour the excavated mixed stone particles onto the top layer of the device. Then, depending on the size of the sieve holes on the screen plate 2, different particle sizes are screened, and the results are recorded and compared to achieve the purpose of rapid testing.

[0029] In the preferred embodiment, two handles 101 are symmetrically arranged on both sides of the fixed frame 1.

[0030] The handle 101 was designed to make it easy to hold and move, and the overall assembly and disassembly are simple, making it easy to store after use.

[0031] In the preferred embodiment, ear plates 102 are symmetrically arranged on both sides of the fixed frame 1, and two adjacent ear plates 102 are connected to the nuts 5 by screws 4.

[0032] After fixing the fixed frames 1 at different heights, the whole structure can be moved to different positions in the rock pile, which facilitates sampling and testing at different locations, ensuring the efficiency of the testing construction. The screws 4 and nuts 5 are easy to operate and have a good fixing effect.

[0033] In a preferred embodiment, the outer side of the fixing frame 1 is also provided with multiple alignment plates 3, which cooperate to form a space for positioning the fixing frame 1.

[0034] During installation, the alignment plate 3 ensures that the two adjacent fixed frames 1 are completely coaxial, thereby improving the accuracy and efficiency of screening, and making installation and disassembly convenient.

[0035] In the preferred embodiment, the outer side of the fixing frame 1 is provided with a threaded hole 103, the fastening nail 6 passes through the alignment plate 3 and the threaded hole 103, and the alignment plate 3 is also provided with a round rod 8 for gripping.

[0036] The alignment plate 3 is preferably a semi-circular plate. When the fastening nail 6 is not fully locked onto the fixing frame 1, the semi-circular direction is downward due to its own weight, and it is in a state of being detached from the upper fixing frame 1. When it is necessary to perform layer-by-layer alignment installation, first, the semi-circular direction of any side of the alignment plate 3 is turned upward and locked. At this time, the same side of the upper fixing frame 1 is pressed against the inner side of the alignment plate 3. Then, the adjacent alignment plates 3 of the lower fixing frame 1 that do not interfere with each other are adjusted in turn. Then, the upper fixing frame 1 is pressed against each other again. Finally, the remaining alignment plates 3 are fully opened to complete the locking of the upper fixing frame 1. The installation of all fixing frames 1 is completed in turn.

[0037] like Figures 6-7 In a preferred embodiment, the sieve plate 2 includes a plate body 201, with third through holes 202 penetrating through both sides of the plate body 201, and the shaft 7 passing through the third through hole 202 and the fixing frame 1 and extending outward.

[0038] The edge of the sieve plate 2 is rounded to ensure easy installation. During installation, the operator straightens the plate through the sieve holes, then aligns the third through hole 202 with the fixed position of the fixed frame 1, and inserts the shaft 7 into the third through hole 202 and the fixed frame 1. The shaft 7 has threads on both sides, and the shaft 7 and the fixed frame are locked by the nut 5.

[0039] In the preferred embodiment, the two sides of the fixing frame 1 are respectively provided with a first through hole 104 and an arc-shaped hole 105, and the shafts 7 on both sides are respectively inserted into the first through hole 104 and the arc-shaped hole 105. The shafts 7 are connected to the fixing frame 1 by nuts 5.

[0040] The arc-shaped hole 105 is relatively close to the inner side of the fixed frame 1. Since the distance between the first through hole 104 and the arc-shaped hole 105 is relatively far, the length of the arc-shaped hole 105d is relatively small compared to the distance between the first through hole 104 and the arc-shaped hole 105. Therefore, when the sieve plate 2 is rotated, the gap between the sieve plate 2 on one side of the arc-shaped hole 105 and the inner side of the fixed frame 1 is small. By setting the sieve plate 2 at a certain tilt angle relative to the fixed frame 1, it is ensured that when the stone particles are detected, they fall from a high place to a low place under the action of gravity through the sieve holes of the sieve plate 2 to complete their screening.

[0041] In a preferred embodiment, the two sides of the plate 201 are respectively provided with rounded corners 203, and the external dimensions of the plate 201 and the internal dimensions of the fixing frame 1 are matched.

[0042] By setting the fillet 203, stability during rotation is ensured, and friction and interference with the inner side of the fixed frame 1 are avoided, ensuring smooth overall use.

[0043] In a preferred embodiment, two screws 106 are symmetrically arranged on the side of the fixed frame 1 that is closer to the arc-shaped hole 105. Multiple screws 106 are connected by a drive plate 9. The drive plate 9 is provided with an inclined surface 904, which is supported on the lower part of the shaft 7.

[0044] The screw 106 is fixed from both sides of the drive plate 9 by cooperating with the nut 5, thereby ensuring that the inclined surface 904 fully supports the shaft 7 and ensures the position and tilt angle of the screen plate 2.

[0045] like Figures 8-9 In a preferred embodiment, the drive plate 9 includes a straight plate 901, on which a plurality of second through holes 902 are provided, and the screw 106 passes through the second through holes 902. A plurality of triangular plates 903 are vertically provided on one side of the straight plate 901, and the inclined surface 904 is located on the outside of the triangular plates 903.

[0046] The two sides of the straight plate 901 are locked by nuts 5. After the overall position is fixed, the shaft 7 can be supported by the triangular plate 903, which has strong load-bearing capacity and good effect.

[0047] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
