Description

Technical Field

[0001] The present invention relates to the technical field of pavers, and in particular to a symmetrical discharging type combined paving machine. Background Art

[0002] Conventional homogeneous earth dams are required by the specification: vertical drainage should be used for homogeneous dams, and horizontal drainage should be set at the bottom to lead the seepage water out of the dam. The project built by the applicant is a homogeneous earth dam with a dam axis length of 16.5km. A longitudinal drainage body is set along the dam axis, and a comb-shaped drainage body is set perpendicular to the dam axis with a spacing of 120m.

[0003] During the actual construction process, it was found that due to the long dam line and the fact that the drainage body was composed of three types of materials (or even more), the construction efficiency was low, so a combined paver was used on site. Summary of the invention

[0004] The object of the present invention is to provide a symmetrical discharging combined paver to solve the problem of how to achieve symmetrical discharging of aggregate boxes arranged in sequence in the travel direction.

[0005] To achieve the above-mentioned objectives, a symmetrical discharge type combined paver is provided. In the first aspect, the paver comprises a basic aggregate box and at least one extended aggregate box, wherein the basic aggregate box is used for paving drainage material; the basic aggregate box and the extended aggregate box are arranged in sequence along the direction of movement of the paver; and the direction of movement of the paver is determined as the front side, and the basic aggregate box is located on the rear side of the paver; the extended aggregate box is used for paving thick filter material on both sides of the drainage material paving path; wherein, during the movement of the paver, the thick filter material is spread on both sides in advance to form a barrier for providing lateral support force to the drainage material paved later.

[0006] Specifically, the basic aggregate box is arranged at the rear of the paver, and then the extended aggregate box is arranged in front of the basic aggregate box. In this way, the maximum width of the feeding port on the top of both the basic aggregate box and the extended aggregate box can reach the width level of the drainage body, so that the feeding amount can be larger and more convenient;

[0007] Secondly, a basic aggregate box paving opening is arranged at the bottom of the basic aggregate box, and extended aggregate box paving openings are symmetrically arranged at the bottom of the extended aggregate box with the drainage material paving path as the symmetry axis. A material guide plate connected in a "V" shape is arranged in the extended aggregate box, and the two ends of the material guide plate are respectively connected to the extended aggregate box paving openings on both sides of the bottom of the extended aggregate box where it is located. Therefore, in the process of the paver moving forward, the front extended aggregate box will discharge material to both sides (i.e., symmetrical discharge). Firstly, it can improve the paving efficiency, and secondly, the material paved in front can provide a lateral supporting force for the material coming out later. When the material in the basic aggregate box comes out, it will be subject to the maximum lateral supporting force. The material in the basic aggregate box is usually the drainage material with the largest particle size, and under the action of the lateral supporting force, it can effectively prevent the drainage material from sliding to both sides.

[0008] Moreover, the extended aggregate box in front discharges materials to both sides, which can form a continuous material layer in front of the paver. In this way, when the materials in the basic aggregate box are released, there is already support in front, which can better bear the weight of subsequent materials. Compared with discharging a row of materials at the same time, all materials are released at the same time, which may cause uneven lateral pressure in the moment, thus affecting the stability of the materials.

[0009] Preferably, when the number of the extended aggregate boxes is two or more, the spacing between the two extended aggregate box paving openings on the front side is greater than the spacing between the two extended aggregate box paving openings on the rear side, and it is ensured that the inner sides of the two extended aggregate box paving openings on the front side of the basic aggregate box paving opening are collinear with the outer sides of the basic aggregate box paving opening, and the inner sides of the two extended aggregate box paving openings on the front side are collinear with the outer sides of the two extended aggregate box paving openings on the rear side.

[0010] The top height of the guide plate is lower than the upper edge height of the extended material collection box. Based on this, the guide plate has two functions, namely:

[0011] Guide the thick filter material in the extended aggregate box to the material openings of the extended aggregate box on both sides to achieve symmetrical material discharge and avoid accumulation of thick filter material in the extended aggregate box;

[0012] The guide plate only diverts the thick filter material in the extended aggregate box, and does not separate the extended aggregate box into two chambers. Therefore, there is no need to feed them separately when filling, ensuring that the maximum width of the feeding port can reach the width level of the drainage body. Moreover, the thick filter material in the space above the guide plate can be guided by it and discharged evenly through the extended aggregate box paving ports on both sides, ensuring the consistency of discharge on both sides.

[0013] On the other hand, side panels are provided on both sides of the bottom of the basic aggregate box paving opening and the extended aggregate box paving opening. Under the support of the side panels, the bottoms of the basic aggregate box paving opening and the extended aggregate box paving opening form a basic aggregate box blanking space and an extended aggregate box blanking space respectively;

[0014] Among them, fixed plates are arranged on the upper rear side of the blanking space of the basic aggregate box and the blanking space of the extended aggregate box. An adjusting screw is vertically threadedly connected to the fixed plate. The bottom end of the adjusting screw is rotatably connected to a scraper plate. The adjusting screw can be raised or lowered by forward or reverse rotation to control the paving thickness of the material between 10-50mm.

[0015] In another aspect, the basic aggregate box and the extended aggregate box are both symmetrically provided with two inner plates;

[0016] The material guide plate in the extended material collecting box is composed of two straight plates, and the top ends of the two straight plates are rotatably connected;

[0017] Wherein, the width of the material paving opening of the basic aggregate box is adjusted by moving the bottom ends of the two inner plates away from or close to each other;

[0018] The inner plate and the bottom ends of the straight plate on the same side of the extended aggregate box are moved away from or close to each other to achieve the adjustment of the width of the material paving opening of the extended aggregate box on this side.

[0019] Specifically, the power sources for the bottom ends of the two inner plates of the basic aggregate box to move away from or toward each other, and for the bottom ends of the inner plates and the straight plates on the same side of the extended aggregate box to move away from or toward each other are telescopic rods, wherein:

[0020] The bottom ends of the inner plates in the basic material collection box and the extended material collection box are both rotatably connected to a side plate, and a telescopic rod is provided between the basic material collection box and the extended material collection box and the inner plate;

[0021] The bottom end of the straight plate is rotatably connected with a side plate, and the bottom of the extended material collecting box is provided with a vertical plate between the side plates at the bottom ends of the two straight plates, and a telescopic rod is provided between the two.

[0022] In addition, all the side panels mentioned above are in a vertical state, the purpose of which is to ensure that the materials on the same section can be distributed according to the preset size.

[0023] In addition, the basic aggregate box and the extended aggregate box, as well as the extended aggregate box and the extended aggregate box, are detachably connected so that the basic aggregate box and the extended aggregate box can be disassembled and replaced according to actual needs.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In view of the symmetrical material distribution method based on a certain material (i.e., material 1), a first embodiment is proposed. This embodiment discloses a symmetrical discharging combined paving machine, see Figure 1 In the figure, reference numeral 110 is a basic aggregate box, 200A is a first extended aggregate box, and 200B is a second extended aggregate box. The basic aggregate box 110, the first extended aggregate box 200A, and the second extended aggregate box 200B are arranged in sequence along the travel direction of the paver. The basic aggregate box 110 is filled with drainage material, the first extended aggregate box 200A is filled with thick filter material 2, and the second extended aggregate box 200B is filled with thick filter material 1, wherein:

[0040] Thick filter material is spread on both sides of the drainage material;

[0041] Thick filter material 1 is spread on both sides of thick filter material 2;

[0042] like Figure 2 As shown, through the above-mentioned laying method, the following are obtained: thick filter material one - thick filter material two - drainage material - thick filter material two - thick filter material one.

[0043] Combination Figure 1 and Figure 3 As shown, the bottom of the basic aggregate box 110 is provided with a basic aggregate box paving opening 120. Figure 3 In the figure, a dotted line is drawn along the travel direction of the combined paver and through the central axis of the basic aggregate box paving opening 120, and the travel line of the combined paver in this embodiment (i.e., the paving path of the drainage material) is indicated by the dotted line. The bottom of the first extended aggregate box 200A is located on the left and right sides of the travel line, and the first extended aggregate box paving opening 220A2 and the second extended aggregate box paving opening 220A1 are respectively provided. The bottom of the second extended aggregate box 200B is located on the left and right sides of the travel line, and the third extended aggregate box paving opening 220B2 and the fourth extended aggregate box paving opening 220B1 are respectively provided.

[0044] The expanded aggregate box paving openings on the left and right sides of the basic aggregate box paving opening 120 are distributed in a stepped manner, and the distance between the expanded aggregate box paving opening and the line of travel is greater as it is extended forward. The purpose is to enable the thick filter material 1 and the thick filter material 2 to fall on both sides of the drainage material in sequence after the material falls through the expanded aggregate box paving opening. Figure 2 The cloth method shown.

[0045] Back to Figure 1 A first material guide plate 210A and a second material guide plate 210B are respectively provided in the first extended material collection box 200A and the second extended material collection box 200B, see Figure 4 As shown, the first guide plate 210A and the second guide plate 210B are both inverted "V" shaped structures, and the specific connection method is as follows:

[0046] See also Figure 5 and Figure 6As shown in the figure, the reference numeral A is an iron shell, B1 and B2 are respectively the first iron partition and the second iron partition, C1 and C2 are respectively the first iron "V"-shaped plate and the second iron "V"-shaped plate, firstly, the iron shell A is welded, and then the first iron partition B1 and the second iron partition B2 are welded inside the iron shell A, and then the first iron partition B1 and the second iron partition B2 are welded inside the iron shell A. Figure 3 and Figure 5 As shown, the first iron partition plate B1 and the second iron partition plate B2 are used to separate the basic aggregate box 110, the first extended aggregate box 200A and the second extended aggregate box 200B. At this time, the basic aggregate box 110 has a basic aggregate box paving opening 120 at the bottom, the first extended aggregate box 200A has a first extended aggregate box paving opening 220A2 and a second extended aggregate box paving opening 220A1 at the two outer sides adjacent to the basic aggregate box paving opening 120, and the second extended aggregate box paving opening 220A2 and the second extended aggregate box paving opening 220A1 at the bottom of the second extended aggregate box 200B have a third extended aggregate box paving opening 220B2 and a fourth extended aggregate box paving opening 220B1 at the outer sides adjacent to the first extended aggregate box paving opening 220A2 and the outer sides of the second extended aggregate box paving opening 220A1; then, in combination Figure 1 and Figure 6 As shown, the first iron "V"-shaped plate C1 and the second iron "V"-shaped plate C2 are welded in the first extended aggregate box 200A and the second extended aggregate box 200B, respectively, to form the first material guide plate 210A and the second material guide plate 210B, respectively, wherein the first iron "V"-shaped plate C1 and the second iron "V"-shaped plate C2 are opened downward, and the two ends of the first iron "V"-shaped plate C1 are respectively connected to the first extended aggregate box paving opening 220A2 and the second extended aggregate box paving opening 220A1, and the second iron "V"-shaped plate C2 is respectively connected to the third extended aggregate box paving opening 220B2 and the fourth extended aggregate box paving opening 220B1.

[0047] In addition, the material flowing out through the basic aggregate box paving opening 120, the first extended aggregate box paving opening 220A2, the second extended aggregate box paving opening 220A1, the third extended aggregate box paving opening 220B2 and the fourth extended aggregate box paving opening 220B1 has a thickness requirement. Figure 3As shown, a first side panel 1301 and a second side panel 1302 are provided on both sides of the bottom of the basic aggregate box paving opening 120, and the first side panel 1301 and the second side panel 1302 extend to the bottom of the second extended aggregate box paving opening 220A1 and the first extended aggregate box paving opening 220A2, respectively. A third side panel 230A1 is provided on the outer side of the second extended aggregate box paving opening 220A1, and the third side panel 230A1 extends to the bottom of the fourth extended aggregate box paving opening 220B1. A fourth side panel 230A2 is provided on the outer side of the first extended aggregate box paving opening 220A2, and the fourth side panel 230A2 extends to the bottom of the third extended aggregate box paving opening 220B2. Similarly, a fifth side panel 230B2 and a sixth side panel 230B1 are provided on the outer sides of the third extended aggregate box paving opening 220B2 and the fourth extended aggregate box paving opening 220B1, respectively. Figure 3 and 4 As shown, where:

[0048] A first baffle plate 140 is provided at the front side of the bottom of the material paving opening 120 of the basic material collection box, between the first side plate 1301 and the second side plate 1302. The bottom of the material paving opening 120 of the basic material collection box is surrounded by the first side plate 1301, the second side plate 1302 and the first baffle plate 140 to form a basic material collection box drop space 150;

[0049] A second baffle plate 240A1 is provided at the front side of the bottom of the second extended material collection box paving opening 220A1, between the third side plate 230A1 and the first side plate 1301. The bottom of the second extended material collection box paving opening 220A1 is surrounded by the third side plate 230A1, the first side plate 1301 and the second baffle plate 240A1 to form a second extended material collection box drop space 250A1;

[0050] A third baffle plate 240A2 is provided at the front side of the bottom of the first extended aggregate box paving opening 220A2, between the fourth side plate 230A2 and the second side plate 1302, and the bottom of the first extended aggregate box paving opening 220A2 is surrounded by the fourth side plate 230A2, the second side plate 1302 and the third baffle plate 240A2 to form a first extended aggregate box drop space 250A2;

[0051] Similarly, a fourth baffle 240B2 and a fifth baffle 240B1 are respectively provided at the front sides of the bottom of the third extended aggregate box paving opening 220B2 and the fourth extended aggregate box paving opening 220B1, and a third extended aggregate box blanking space 250B2 and a fourth extended aggregate box blanking space 250B1 are respectively formed at the bottom of the third extended aggregate box paving opening 220B2 and the fourth extended aggregate box paving opening 220B1.

[0052] When paving, participants Figure 1 , Figure 3 and Figure 4As shown, firstly, the drainage material, the thick filter material 2 and the thick filter material 1 are respectively loaded into the basic aggregate box 110, the first extended aggregate box 200A and the second extended aggregate box 200B, wherein:

[0053] The drainage material in the basic aggregate box 110 directly falls into the basic aggregate box material dropping space 150 through the basic aggregate box material laying opening 120;

[0054] The thick filter material 2 in the first extended material collection box 200A falls into the first extended material collection box material drop space 250A2 and the second extended material collection box material drop space 250A1 through the first extended material collection box material drop opening 220A2 and the second extended material collection box material drop opening 220A1 respectively;

[0055] The thick filter material 1 in the second extended aggregate box 200B falls into the third extended aggregate box material placement space 250B2 and the fourth extended aggregate box material placement space 250B1 through the third extended aggregate box material placement opening 220B2 and the fourth extended aggregate box material placement opening 220B1 respectively.

[0056] See also Figure 7 As shown ( Figure 7 In the figure, the position of the combined paver is determined by the paving opening 120 of the basic aggregate box), the combined paver in the initial position forms an initial dropping area after the above-mentioned dropping, and then the combined paver moves forward one path segment (the length of one path segment is equal to the length of one basic aggregate box paving opening 120), forming a first path segment and a first path segment dropping area, at which time the drainage material in the first path segment dropping area overlaps with part of the thick filter material 2 in the initial dropping area; then, it moves forward one path segment again to form a second path segment and a second path segment dropping area, the drainage material in the second path segment dropping area, part of the thick filter material 2 in the first path segment dropping area and part of the thick filter material 1 in the initial dropping area overlap to obtain an overlapping section; thereafter, as the combined paver continues to move the cabinet, the paving distance of the overlapping section gradually increases.

[0057] Among them, the distribution of the material section in the overlap section is as follows: Figure 2 As shown, that is, "thick filter material one - thick filter material two - drainage material - thick filter material two - thick filter material one", the thickness of the material paving is consistent with the height of any one side plate mentioned above (that is, the height of the material dropping space).

[0058] It should be noted that see Figure 7 As shown in the figure, due to the existence of the side plates, there will be gaps between the materials when they are dropped. Since the thickness of the side plates is generally 0.3-0.7cm, and the length of the entire overlapping section is 2m-3m, or even longer, the materials will fall under their own gravity to fill the gaps, and the impact on the thickness of the material paving is negligible;

[0059] As for the vacant parts at the head and tail of the entire blanking area, they are filled manually.

[0060] join Figure 1 and Figure 4 As shown, during the above-mentioned paving process, the role of the first material guide plate 210A is to guide the thick reverse filter material 2 in the first extended aggregate box 200A to the first extended aggregate box paving port 220A2 and the second extended aggregate box paving port 220A1 respectively, so as to realize symmetrical discharge. On the one hand, it avoids the accumulation of the thick reverse filter material 2 in the extended aggregate box 200A. On the other hand, the first material guide plate 210A only diverts the thick reverse filter material 2 in the first extended aggregate box 200A, and does not separate the first extended aggregate box 200A into two chambers. Therefore, it is not necessary to put them separately when filling, thus maintaining the original size of the material receiving opening of the first extended aggregate box 200A. Moreover, the thick reverse filter material 2 in the space above the first material guide plate 210A can be evenly discharged through the first extended aggregate box paving port 220A2 and the second extended aggregate box paving port 220A1 after being guided by the first material guide plate 210A, thus ensuring the consistency of discharge on both sides.

[0061] Similarly, the function of the second material guide plate 210B is to achieve symmetrical material discharge of the second extended material collection box 200B and ensure the consistency of material discharge from the third extended material collection box material opening 220B2 and the fourth extended material collection box material opening 220B1.

[0062] See also Figure 3 As shown, during the above-mentioned paving process, a blanking space is formed at the bottom of each paving opening through the support of the side panels and the baffle plates to spread the material, so that the thickness of the material paving is guaranteed. Usually the paving thickness is 30cm-40cm, and the material discharge direction can also be changed. Because of the obstruction of the side panels and the baffle plates, the material can only enter the blanking space first. At this time, the material cannot slide out to the outside and can only move forward with the combined paver to spread the material backward on the surface to be paved.

[0063] It should be noted that the above-mentioned side panels include a first side panel 1301, a second side panel 1302, a third side panel 230A1, a fourth side panel 230A2, a fifth side panel 230B2 and a sixth side panel 230B1; the above-mentioned baffles include a first baffle 140, a second baffle 240A1, a third baffle 240A2, a fourth baffle 240B2 and a fifth baffle 240B1.

[0064] As an improvement of this embodiment, see Figure 8As shown in the figure, number 300 is a scraper plate, 310 is an adjusting screw rod, and 320 is a fixed plate. One end of the fixed plate 320 is welded and fixed at an upper position on the rear side of the fourth extended aggregate box blanking space 250B1. The adjusting screw rod 310 vertically penetrates the fixed plate 320 and is threadedly connected thereto. The bottom end of the adjusting screw rod 310 is rotatably connected to the scraper plate 300, so that the scraper plate 300 falls on the rear side of the fourth extended aggregate box blanking space 250B1. The scraper plate 300 is preferably tilted. When in use, the adjusting screw rod 310 is rotated with the help of a wrench. By adjusting the forward or reverse rotation of the screw rod 310, the scraper plate 300 can be raised or lowered to adjust the thickness of the thick filter material 1 spread on the surface to be paved. The specific adjustment range is between 10-50mm.

[0065] It should be noted that Figure 8 Taking the fourth extended aggregate box blanking space 250B1 as an example, in fact, corresponding scraper plates 300 are provided on the rear sides of the basic aggregate box blanking space 150, the second extended aggregate box blanking space 250A1, the first extended aggregate box blanking space 250A2 and the third extended aggregate box blanking space 250B2 (the fixed plate 320 can be welded to the wall adjacent to the blanking space).

[0066] As an improvement of this embodiment, see Fig. 9 As shown, reference numeral 400 in the figure is an expansion bin, and the expansion bin 400 is arranged on the top of the basic aggregate box 110, the first extended aggregate box 200A and the second extended aggregate box 200B. The expansion bin 400 not only expands the capacity on the basis of the original aggregate box, but also adopts a flared design, which is also convenient for feeding.

[0067] also, Fig. 9 In the figure, reference numeral 500 is a connecting ear. When there is an expansion bin 400, the connecting ear 500 is fixed on the top edge of the expansion bin 400 (i.e., the solid line portion). When there is no expansion bin, the connecting ear 500 is fixed on the top edge of the aggregate box (i.e., the dotted line portion), wherein:

[0068] The function of the connecting ear 500 is to connect the towing rope to achieve the purpose of towing the paver. Usually, a mobile device such as an engineering vehicle is used to tow the paver forward to achieve the paving of materials.

[0069] As an improvement of this embodiment, see Fig.10 As shown, reference numeral 600 is a tire, and reference numeral 610 is a tire axle. A tire axle 610 is disposed in the bottom chamber of the second guide plate 210B. The tire axle 610 is disposed parallel to the x-axis, and the tire 600 is coaxially rotatably connected to the tire axle 610.

[0070] When using, see Fig.11As shown, when the paver is dragged forward as a whole, the tire 600 arranged on the front side greatly improves the maneuverability of the paver. On uneven terrain, the front tire 600 can better adapt to the ups and downs of the surface to be paved and maintain the stability of the bucket. In addition, the tire 600 arranged on the front side will not interfere with the falling process of the material, and the tail of the paver will generate up and down shaking, which helps to break the adhesion between the materials and makes it easier for the materials to slide out of their respective aggregate boxes.

[0071] Second embodiment, see Fig.12 As shown, the basic aggregate box 110, the first extended aggregate box 200A and the second extended aggregate box 200B are arranged in sequence along the travel direction of the paver. In this embodiment, the basic aggregate box 110, the first extended aggregate box 200A and the second extended aggregate box 200B can be disassembled and replaced.

[0072] Similarly, a basic aggregate box material paving opening 120 is provided at the bottom of the basic aggregate box 110, a first extended aggregate box material paving opening 220A2 and a second extended aggregate box material paving opening 220A1 are provided at the bottom of the first extended aggregate box 200A on the left and right sides of the line, respectively, and a third extended aggregate box material paving opening 220B2 and a fourth extended aggregate box material paving opening 220B1 are provided at the bottom of the second extended aggregate box 200B on the left and right sides of the line, respectively. Fig.12 (not shown), but a U-shaped side plate 113 is provided at the bottom of each material laying opening, and its function is to enclose the same material dropping space as in the first embodiment, with the difference that: the U-shaped side plate 113 can be replaced synchronously with the aggregate box.

[0073] It should be noted here that:

[0074] In the first and second embodiments, three aggregate boxes are provided. That is because only three types of materials are needed in the dam line paving process of the homogeneous earth dam. However, when actual needs change, more aggregate boxes can be provided, but at least two. In the first embodiment, once the paver is completed, the aggregate box cannot be disassembled and replaced; in the second embodiment, the aggregate box can be flexibly adjusted according to actual needs. On the one hand, the number of paving layers of the material in the horizontal direction can be increased, and on the other hand, the width of the material paving can be adjusted, which is generally adjusted between 30-50cm.

[0075] The third embodiment, see Fig.13As shown, reference numeral 110 in the figure is a basic aggregate box, two basic inner plates 114 are symmetrically arranged in the basic aggregate box 110, a basic movable plate 1141 is arranged at the bottom of the two basic inner plates 114, a first telescopic rod is arranged between the basic movable plate 1141 and the basic aggregate box 110 and the basic movable plate 1141, and the width of the basic aggregate box blanking space 150 formed between the two basic movable plates 1141, i.e., the width when the drainage material is spread, is adjusted by telescoping the first telescopic rod;

[0076] See also Fig.14 As shown in the figure, number 200 is an extended aggregate box, and two extended inner panels 210 are symmetrically arranged in the extended aggregate box 200, and the bottoms of the two extended inner panels 210 are rotatably connected with movable side panels 211, and a second telescopic rod is arranged between the movable side panels 211 and the extended aggregate box 200, and the extension and contraction of the second telescopic rod is used to adjust the position of the movable side panels 211.
