Abstract
Description
Technical Field
[0001] The present application relates to the technical field of screening devices, and more specifically, to a roadbed filler screening device. Background Art
[0002] During highway roadbed construction, a large amount of roadbed filler is needed as construction material, and the particle size of the roadbed filler needs to be strictly controlled within the specified requirements to ensure the quality of the roadbed filling. Otherwise, quality problems such as roadbed subsidence and insufficient bearing capacity will occur. Therefore, during roadbed construction, the roadbed filler needs to be screened.
[0003] The document with the prior art publication number CN218531700U provides a raw material screening device for the construction of silty lime soil roadbed, which vibrates and screens the preliminary solidified soil material on the screen plate through a vibrating screen component to screen out the fine material and let the coarse material fall into the coarse material hopper, and then the coarse material is crushed by a crushing component installed in the coarse material hopper, so that the preliminary solidified soil material with large differences in original particle size is finally processed into fine material. In the process of vibrating and screening the material, the adjusting component can adjust the inclination angle of the screen plate by moving one end of the screen plate up and down, so as to better make the coarse material fall into the coarse material hopper, which can solve the problems of high construction period and construction cost of traditional preliminary solidified soil material processing methods.
[0004] Although the device has many beneficial effects, the following problems still exist: when screening roadbed fillers, only fillers of fixed specifications can be screened, and it is difficult to screen fillers of different specifications according to different situations, which can easily narrow the scope of application of the device. In view of this, we propose a roadbed filler screening device. Utility Model Content

DETAILED DESCRIPTION
[0026] The present application is further described in detail below in conjunction with the accompanying drawings.
[0027] Reference Figure 1 and Figure 2, this embodiment of the present application discloses a subgrade filler screening device. The subgrade filler screening device includes: a support frame 1;
[0028] On both sides of the top of the support frame 1, a screening mechanism 3 for screening subgrade fillers is provided;
[0029] The screening mechanism 3 includes a support plate 31. The support plate 31 is located at the top of the support frame 1. A first through groove 38 is formed through one side of the support plate 31. A plurality of screening rods 33 are arranged at equal intervals on one side of the support plate 31. An opening is formed through the top of the screening rod 33. A plurality of vertical rods 32 for cooperating with the opening are fixedly connected to the top of the support plate 31, and the vertical rods 32 are located within the opening. Second through grooves for the subgrade fillers passing through the gaps between the screening rods 33 are formed through both sides of the support frame 1, thereby facilitating the staff to screen subgrade fillers of different specifications according to requirements and expanding the applicable range of the device.
[0030] Refer to Figure 1 and Figure 2 , the cross-section of the support frame 1 is in the shape of an isosceles trapezoid, and the size of the inner top of the support frame 1 is larger than the size of its inner bottom. The cross-section of one of the support plates 31 is in the shape of a factory character, and the two support plates 31 are arranged in a mirror image, so as to facilitate the un-screened subgrade fillers that do not pass through the gaps between the screening rods 33 to slide down quickly along the direction of the screening rods 33.
[0031] Refer to Figure 1 , the top of the support frame 1 is closed, and the bottom of the support frame 1 is open, so that the subgrade fillers passing through the gaps between the screening rods 33 can fall to the ground, facilitating the staff to collect them later.
[0032] Refer to Figure 1 and Figure 3 , connecting rods 39 are slidably connected to both sides of the top of the support plate 31. A baffle 34 is fixedly connected between the two connecting rods 39, and the bottom of the baffle 34 is in contact with the top of the screening rod 33, so as to prevent the screening rod 33 from moving upward.
[0033] Refer to Figure 3 , chutes are formed on both sides of the top of the support plate 31. Sliders 35 are slidably connected within the chutes. The top of the sliders 35 is fixedly connected to the bottom ends of the connecting rods 39, so as to facilitate the baffle 34 to move along the direction of the chutes.
[0034] Refer to Figure 3 , a cross bar 36 is fixedly connected within the chutes. The sliders 35 are slidably sleeved outside the cross bar 36, so as to prevent the sliders 35 from disengaging from the chutes.
[0035] Refer to Figure 3A spring 37 is fixedly connected to one side of the slider 35, one end of the spring 37 is fixedly connected to one side of the inner wall of the slide groove, and the spring 37 is sleeved on the outside of the cross bar 36 to prevent the slider 35 from moving at will.
[0036] Reference Figure 3 A handle is fixedly connected to the top of the baffle 34 to facilitate the staff to pull the baffle 34 to move.
[0037] Reference Figure 1 Two universal wheels 2 are installed on both sides of the bottom of the support frame 1 to facilitate the staff to move the device.
[0038] Reference Figure 1 and Figure 2 , threaded rods 4 are threadedly connected on both sides of the top of the support plate 31, and two threaded grooves are provided on both sides of the top of the support frame 1, and the threaded rods 4 are threadedly connected in the threaded grooves, so that it is convenient for the staff to disassemble and assemble the support plate 31.
[0039] The implementation principle of a roadbed filler screening device in an embodiment of the present application is as follows: when it is necessary to screen roadbed fillers of different specifications, the staff can pull the baffle 34 to move, and the movement of the baffle 34 can drive the slider 35 to move through the connecting rod 39, so that the slider 35 moves along the direction of the cross bar 36 and squeezes the spring 37, so that the baffle 34 moves to a position away from the screening rod 33, and then the staff removes one screening rod 33 between every three screening rods 33 from the outside of the vertical rod 32, and then loosens the baffle 34, so that the squeezed spring 37 resets and rebounds to drive the slider 35 to move, and the movement of the slider 35 can drive the baffle 34 to move through the connecting rod 39, so that the baffle 34 moves to the top of the screening rod 33. At this time, the distance between the two adjacent screening rods 33 is increased, so that larger roadbed fillers can also pass through the gap between the screening rods 33 and fall into the inner side of the support frame 1.
[0040] The embodiment of the present application provides a roadbed filler screening device. By setting up a screening mechanism 3, when screening the roadbed filler, the staff can remove screening rods 33 of different numbers and positions, so that the gap width between adjacent screening rods 33 changes, thereby facilitating the screening of fillers of different specifications and expanding the scope of application of the device.
