Description

Technical Field

[0001] The utility model belongs to the technical field of pavement cushion filler treatment equipment, and particularly relates to a device for removing oversize materials from pavement cushion fillers. Background Art

[0002] Pavement cushion fillers play an important role in highway construction. Their main functions include water storage, drainage, heat insulation, frost prevention, etc. The selection of cushion materials and the construction quality directly affect the stability and service life of the pavement. In fact, the sizes of materials in most quarries and natural river channels are uneven. To ensure the compaction degree and surface flatness, oversize materials need to be removed before feeding or rolling. Usually, manual removal is adopted, which has a huge workload, is difficult to remove completely, and cannot guarantee the quality.

[0003] Currently, the removal device includes a spring buffer layer, spring support rods, a first inclined frame, and a second inclined frame. The first inclined frame and the second inclined frame intersect at the top beam, and equally spaced bars are also provided on the first inclined frame and the second inclined frame. During the loading process, the oversize materials are screened through the bars on the first inclined frame and the second inclined frame to achieve the purpose of removing oversize materials. However, since the first inclined frame, the second inclined frame, and the bars are all straight, and the width of the hopper is limited, when screening the fillers, after pouring the fillers on the first inclined frame, the second inclined frame, and the bars, they will slide quickly to both sides. Moreover, due to gravity and acceleration, the fillers will roll faster and faster, resulting in oversize materials carrying some appropriately sized fillers to roll, and some appropriate fillers will scatter outside the hopper again, reducing the screening effect of the fillers. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a device for removing oversize materials from pavement cushion fillers, which can slow down the rolling speed of the fillers and improve the screening effect of the fillers.

[0005] The device for removing oversize materials from pavement cushion fillers includes two horizontally arranged and parallel fixed plates on the left and right. Inclined frames are fixedly inclined at the tops of the two fixed plates. A connecting mechanism for connecting them to the hopper is arranged at the bottom of the fixed plates. First baffles for preventing pavement cushion fillers from separating are fixed on both the front and rear sides of the inclined frames.

[0006] The inclined frame includes a first grid plate and a third grid plate arranged obliquely. The bottom of the first grid plate is fixed to the fixed plate, and the first grid plate and the third grid plate are fixed by a horizontally arranged second grid plate.

[0007] Furthermore, the tops of the two third grid plates are fixed by a horizontally arranged fourth grid plate, and the width of the second grid plate is smaller than that of the oversize materials.

[0008] Further, a second baffle for blocking oversize materials is vertically arranged on the outer side of the fixed plate. The second baffle is fixed to the fixed plate through a fixing rod, and a gap for the oversize materials to pass through is left between the second baffle and the fixed plate.

[0009] Further, a plurality of parallel connecting rods are horizontally arranged below the fourth grid plate. The ends of the connecting rods are fixed to the second grid plate, and a support rod is vertically fixed between the connecting rods and the fourth grid plate.

[0010] Further, a freely rotatable sleeve is independently sleeved on the connecting rod.

[0011] Further, the connecting mechanism includes a clamping groove with a downward-facing notch, and the clamping groove has no front and rear side walls.

[0012] Further, a spring is vertically fixed between the fixed plate and the fixed block.

[0013] Further, fixed blocks are vertically fixed to the bottom of the fixed plate on the left and right sides of the spring. A sliding groove for the fixed block to be inserted and slide up and down is opened at the top of the clamping groove.

[0014] Further, a limiting component for preventing the fixed block from detaching is arranged in the sliding groove.

[0015] Further, the limiting component includes a limiting block fixed at the notch of the sliding groove, and a limiting groove for the limiting block to be inserted and slide up and down is opened on the fixed block.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The utility model blocks the roadbed cushion filler on the third grid plate through the second grid plate, thereby slowing down the rolling speed of the roadbed cushion filler on the third grid plate, increasing the overall rolling time of the roadbed cushion filler on the third grid plate, the second grid plate and the first grid plate, making the screening effect better. While removing oversize materials, it can reduce the oversize materials from carrying some suitable fillers and dropping them on both sides of the hopper, reducing the secondary collection of suitable fillers.

[0022] The following further illustrates the present utility model through specific embodiments in conjunction with the accompanying drawings, but it is not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present invention.

[0023] An apparatus for removing oversized materials from the filler of a roadbed cushion described in this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, includes two horizontally arranged and parallel fixed plates 1 on the left and right. The distance between the two fixed plates 1 is the same as the width of the truck bed used for loading the roadbed cushion filler. The tops of the two fixed plates 1 are both inclined and fixed with inclined frames. The two inclined frames form a herringbone structure as a whole. The top of the left inclined frame inclines to the right, and the top of the right inclined frame inclines to the left. First baffles for preventing the roadbed cushion filler from detaching are fixed on the front and back sides of the two inclined frames. Through the first baffles, the rolling of the roadbed cushion filler can be restricted, so that the roadbed cushion filler can only slide from both sides and will not slide from the front and back sides, and the roadbed cushion filler can be screened.

[0024] The inclined frame includes an inclined first grid plate 2 and a third grid plate 4. The bottom of the first grid plate 2 is fixed to the fixed plate 1. The first grid plate 2 and the third grid plate 4 are fixed by a horizontally arranged second grid plate 3. One end of the second grid plate 3 is fixed to the bottom of the third grid plate 4, and the other end of the second grid plate 3 is fixed to the top of the first grid plate 2. The first grid plate 2, the second grid plate 3, and the third grid plate 4 are existing grid plates, and the gap of their grids is smaller than the size of the oversized materials, that is, the oversized materials cannot pass through their grids.

[0025] The tops of the two third grid plates 4 are fixed by a horizontally arranged fourth grid plate 6. Through the fourth grid plate 6, it can be avoided that the intersection at the top of the two third grid plates 4 is in a sharp shape, so that the roadbed cushion filler can stay on the fourth grid plate 6 for a while, and the fourth grid plate 6 can screen the roadbed cushion filler. The width of the second grid plate 3 is smaller than the oversized materials. Since the oversized materials are smaller than the width of the second grid plate 3, when the oversized materials stay on the second grid plate 3, they will also slide down, effectively avoiding the oversized materials being stuck on the second grid plate 3.

[0026] A second baffle for blocking oversize materials is vertically arranged on the outer side of the fixed plate 1. There are two second baffles, which are respectively located on the left and right sides. The second baffles are fixed to the fixed plate 1 through fixing rods. There are two fixing rods, and the two fixing rods are respectively fixed on the front and back sides of the second baffle and the fixed plate 1. A gap for the oversize materials to pass through is left between the second baffle and the fixed plate 1. The second baffle can block the sliding oversize materials and prevent the oversize materials from sliding randomly and causing harm to people.

[0027] A number of parallel connecting rods 7 are horizontally arranged below the fourth grid plate 6. The connecting rods 7 are parallel to each other in the front and back. The ends of the connecting rods 7 are fixed to the second grid plate 3. The two ends of the connecting rods 7 are respectively fixed to the second grid plates 3 on the left and right sides. A support rod 5 is vertically fixed between the connecting rod 7 and the fourth grid plate 6. The connecting rod 7 and the support rod 5 can increase the force-bearing effect, stability and load-bearing capacity.

[0028] A freely rotatable sleeve 8 is independently sleeved on the connecting rod 7. When the roadbed cushion filler falls from the fourth grid plate 6 and the third grid plate 4, due to the blocking of the fourth grid plate 6 and the third grid plate 4, the falling direction of the roadbed cushion filler will be changed, and the roadbed cushion filler will hit the connecting rod 7. Through the free rotation of the sleeve 8, when the roadbed cushion filler hits the sleeve 8, the rolling of the sleeve 8 will have a certain force-dissipating effect, reducing the force of the roadbed cushion filler hitting the connecting rod 7 and the sleeve 8.

[0029] A card slot 9 with a downward-facing notch is arranged at the bottom of the fixed plate 1. The card slot 9 has no front and rear side walls, and the overall structure of the card slot 9 is in a "C" shape. Since the truck bed is a rectangular structure, by inserting the card slot 9 into the top of the side wall of the truck bed, the fixed plate 1 is connected to the truck bed. Moreover, the way of inserting the card slot 9 enables the fixed plate 1 and the truck bed to be detachably matched. When screening the roadbed cushion filler, it is installed on the truck bed. After screening, it can be removed, so there is no need to install it on each vehicle. Multiple can be prepared and used alternately, and can also be replaced. In some embodiments, the fixed plate 1 can also be directly welded and fixed to the truck bed. The whole content of this paragraph constitutes a connecting mechanism for connecting the fixed plate 1 and the truck bed.

[0030] A spring 11 is vertically fixed between the fixed plate 1 and the fixed block 10. The spring 11 can buffer and reduce the impact of the roadbed cushion filler on the truck bed. Moreover, through the spring 11, the third grid plate 4, the second grid plate 3 and the first grid plate 2 can be shaken up and down, increasing the screening effect.

[0031] On both the left and right sides of the spring 11, fixed blocks 10 are vertically fixed to the bottom of the fixed plate 1. At the top of the card slot 9, a sliding groove is opened for the fixed block 10 to be inserted and slide up and down. The sliding groove is located at the top of the side wall of the card slot 9. The fixed block 10 can block the filling material of the roadbed cushion, preventing the filling material of the roadbed cushion from entering the spring 11.

[0032] A limiting block 12 is fixed at the notch of the sliding groove. A limiting groove for the limiting block 12 to be inserted and slide up and down is opened on the fixed block 10. The limiting groove has a bottom. When the spring 11 is in a natural state, the limiting block 12 contacts the bottom of the limiting groove, and there is a gap between the limiting block 12 and the top of the limiting groove. The limiting block 12 can prevent the fixed block 10 from disengaging from the sliding groove. When freely removing the third grid plate 4, the second grid plate 3, and the first grid plate 2, it can prevent the card slot 9 from disengaging, increasing the connection effect between the card slot 9 and the fixed plate 1.

[0033] The above content as a whole constitutes a limiting component for preventing the fixed block 10 from disengaging from the sliding groove. Of course, in some embodiments, the limiting component can also be that first limiting plates are fixed on both the left and right sides of the fixed block 10, and second limiting plates for preventing the first limiting plates from disengaging are fixed at the notch.

[0034] Working process:

[0035] During use, insert the two card slots 9 into the top of the side walls in the width direction of the truck bed. Place the first grid plate 2, the second grid plate 3, and the third grid plate 4 on the top of the truck bed. Transport the filling material of the roadbed cushion to the top of the truck bed, so that the filling material of the roadbed cushion falls on the top of the fourth grid plate 6 and then slides off from both sides. The fourth grid plate 6, the third grid plate 4, the second grid plate 3, and the first grid plate 2 screen out the oversize materials in the filling material of the roadbed cushion. The filling materials that are not oversize materials fall from the fourth grid plate 6, the third grid plate 4, the second grid plate 3, and the first grid plate 2, while the oversize materials slide off from both sides. Due to the presence of the second grid plate 3, when the filling material of the roadbed cushion slides from the third grid plate 4, it will be blocked by the second grid plate 3, thereby slowing down the rolling speed of the filling material of the roadbed cushion, enabling the filling materials that are not oversize materials in the filling material of the roadbed cushion to fall, improving the screening effect on the filling material of the roadbed cushion, effectively reducing some filling materials of the roadbed cushion that are not oversize materials from sliding to both sides of the truck bed, reducing secondary collection, and moreover, due to the presence of the second grid plate 3, the inclination degrees of the third grid plate 4 and the first grid plate 2 can meet the requirements while the filling material of the roadbed cushion is rolling, increasing the rolling time of the filling material of the roadbed cushion; when the truck bed is filled with the appropriate filling material of the roadbed cushion, remove the card slot 9 from the truck bed, and then the filling material of the roadbed cushion can be directly transported to the construction site for use without having to remove it on-site.
