Description

TECHNICAL FIELD

[0001] The utility model relates to road surface construction technical field, especially a kind of material supplementing device for asphalt paving. BACKGROUND

[0002] At present, in the process of ultra-thin asphalt paving construction, due to the fine asphalt material, paving gap often occurs when paving machine paving, and the construction personnel need to return to the rear to observe whether there is a large gap, and timely supplement material. However, many construction personnel are needed for paving in front of the paving machine, and it is difficult to pay attention to the place that needs to be supplemented in the rear through manual material supplementing (which needs to carry, fill and pave the material supplementing in multiple processes), thereby causing paving quality problems. Therefore, in order to improve the material supplementing efficiency, the material supplementing device is designed to efficiently fill and supplement the paving gap for a single person, solving the paving quality problems caused by insufficient personnel.

[0003] However, the existing material supplementing device for asphalt paving is usually a handcart with a rolling wheel and capable of loading asphalt supplementing material. The construction personnel push the handcart to the paving gap, tilt the body to pour out the asphalt supplementing material, and then use the rolling wheel at the bottom of the handcart to roll the asphalt supplementing material, thereby completing the filling and paving. In such a working process, the rolling wheel will accumulate asphalt supplementing material, or the asphalt supplementing material accumulated on the rolling wheel will fall off with the movement. In addition, the amount of poured asphalt supplementing material depends on the experience of the construction personnel, thereby causing uneven paving thickness and uneven road surface, and unable to achieve high-quality filling and paving.

[0032] In the description of the embodiments of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connecting", "connection" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication inside two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0033] The embodiments of the present application are described below in conjunction with Figures 1 to 3 A material supplement device for asphalt paving is described.

[0034] A material replenishing device for asphalt paving includes a handcart 1, a material replenishing pusher 2, a material discharge stop 3, and a roller assembly 4; the top of the handcart 1 has a material discharge port 11, the front of the handcart 1 has a material discharge port 12, and the material replenishing cavity 13 inside the handcart 1 is connected to the material discharge port 11 and the material discharge port 12.

[0035] The feeding pusher 2 is disposed in the feeding cavity 13 and pushes the feeding material to the discharge port 12;

[0036] The discharge baffle 3 is set at the discharge port 12, and the discharge port 12 is moved to form a replenishment port 14;

[0037] The roller assembly 4 is located at the bottom of the handcart 1, and the roller assembly 4 is equipped with a material scraping device 41.

[0038] In a preferred embodiment of the present invention, a patching device for asphalt paving is provided, such as... Figures 1 to 3 As shown, the filling chamber 13 inside the wheelbarrow 1 connects the discharge port 11 and the outlet 12. After asphalt filler is put into the discharge port 11, it can be loaded into the filling chamber 13. When the wheelbarrow 1 moves to the paving gap that needs to be filled, the filling pusher 2 pushes the asphalt filler in the filling chamber 13 from the outlet 12 to the paving gap. Then, the roller assembly 4 at the bottom of the wheelbarrow 1 compacts it, thus achieving paving and filling. More importantly, since the outlet 12 can be dynamically blocked by the outlet baffle 3 to form an adjustable filling port 14, the size of the filling port 14 can be adjusted to match the size of the paving gap, controlling the filling amount and avoiding overfilling. In addition, the roller assembly 4 is equipped with a filling scraper 41 to repeatedly scrape off the asphalt filler accumulated on the roller assembly 4 during the compaction process, ultimately resulting in a better flatness at the filled area and achieving high-quality filling and paving.

[0039] Furthermore, the discharge baffle 3 includes a horizontal baffle 31 and a vertical baffle 32; the horizontal baffle 31 movably blocks the upper part of the discharge port 12, the vertical baffle 32 movably blocks the right part of the discharge port 12, and the lower side of the horizontal baffle 31, the left side of the vertical baffle 32 and the discharge port 12 together form a replenishment port 14.

[0040] In this embodiment, the movable discharge blocking piece 3 blocks the discharge port 12, which is achieved by a horizontal baffle 31 and a vertical baffle 32. The horizontal baffle 31 blocks the upper part of the discharge port 12, and the vertical baffle 32 blocks the right part of the discharge port 12. The lower edge of the horizontal baffle 31, the left edge of the vertical baffle 32, and the discharge port 12 form a replenishment port 14, so that by adjusting the height of the horizontal baffle 31 blocking the upper part of the discharge port 12 and the area of the vertical baffle 32 blocking the right part of the discharge port 12, the size of the replenishment port 14 is determined. It should be noted that the width of the replenishment port 14 corresponds to the width adjustment of the paving gap (width adjustment is more important and needs to be more accurate), and the height of the replenishment port 14 corresponds to the thickness adjustment of the paving gap (thickness adjustment does not need to be very accurate, and the thickness can be calibrated by filling back and forth several times), so that the handcart 1 can pass through the paving gap and accurately fill the amount of replenishment and compact it at one time, thereby improving the paving efficiency.

[0041] Further, a plug-in groove 121 is formed on the right front side of the discharge port 12, and a plurality of first adjustment protrusions 122 are equidistantly arranged on the bottom front side of the discharge port 12. The bottom end of the vertical baffle 32 is provided with a first adjustment groove 321 corresponding to the first adjustment protrusions 122, and the right part of the vertical baffle 32 is inserted into the plug-in groove 121, and the first adjustment groove 321 is freely matched with the first adjustment protrusions 122.

The left rear end and the right rear end of the horizontal baffle 31 are provided with a second adjustment groove 311 and a third adjustment groove 312 corresponding to the second adjustment protrusions 123 and the third adjustment protrusions 124, respectively, and the second adjustment groove 311 and the third adjustment groove 312 are matched with the second adjustment protrusions 123 and the third adjustment protrusions 124 at different levels, respectively.

[0043] The rear face of the vertical baffle 32 and the front face of the horizontal baffle 31 abut.

[0044] In the embodiment, the movable adjustment of the transverse baffle 31 and the vertical baffle 32 at the discharge port 12 is preferably achieved by the vertical baffle 32 in front of the transverse baffle 31 and the limiting by the adjustment protrusions, so as to adjust the shielding position. It should be noted that in the matching mode, the transverse baffle 31 can be first put from the front side of the discharge port 12 and moved to the rear side to make the second adjustment groove 311 and the third adjustment groove 312 respectively match with the second adjustment protrusion 123 and the third adjustment protrusion 124 at different levels, so as to realize the height adjustment of the shielding of the transverse baffle 31; then according to the area required to be shielded at the right part of the discharge port 12, the first adjustment groove 321 is free to match with the first adjustment protrusion 122, so as to determine the area of the right part of the vertical baffle 32 inserted into the insertion slot 121, thereby realizing the adjustment of the shielding area of the right part of the discharge port 12 of the vertical baffle 32, and the back of the vertical baffle 32 and the front of the transverse baffle 31 abut against each other to limit the transverse baffle 31.

[0045] Further, the groove space of the first adjustment groove 321, the second adjustment groove 311 and the third adjustment groove 312 is respectively greater than the first adjustment protrusion 122, the second adjustment protrusion 123 and the third adjustment protrusion 124;

[0046] The top left side of the trolley 1 is provided with a plurality of wire guides 15, one end of a traction wire 16 connected to the top of the transverse baffle 31 and the vertical baffle 32 respectively, and the other end of the traction wire 16 guided along the wire guides 15 to the traction handle 17 at the rear of the trolley 1;

[0047] When the traction handle 17 is pinched, the traction wire 16 is pulled tight.

[0048] In the embodiment, the viscosity of the asphalt supplement is relatively large, and the supplement may be attached to the supplement port 14 during the filling process. Therefore, the adjustment groove is designed to be slightly larger than the adjustment protrusion, the transverse baffle 31 and the vertical baffle 32 are guided along the wire guides 15 to the traction handle 17 at the rear of the trolley 1 by the traction wire 16, so that the construction personnel can shake the transverse baffle 31 and the vertical baffle 32 by repeatedly pinching the traction handle 17, so that the asphalt supplement can be more smoothly discharged from the supplement port 14.

[0049] Further, the rolling wheel assembly 4 includes at least one rolling wheel 42 and a supplement scraping device 41; the rolling wheel 42 and the supplement scraping device 41 are both arranged on the bottom surface of the trolley 1, and the scraping part 411 of the supplement scraping device 41 is close to the rolling surface of the rolling wheel 42.

[0050] In the embodiment, the rolling wheel assembly 4 is preferably composed of at least one rolling wheel 42 and a material supplement scraping device 41. The rolling wheel assembly 4 can be composed of any number of rolling wheels 42 and material supplement scraping devices 41 according to the actual construction terrain, area, and other conditions. The rolling direction of the rolling wheel 42 can be freely selected, but the scraping member 411 of the material supplement scraping device 41 needs to be close to the rolling surface of the rolling wheel 42 to facilitate scraping the asphalt material attached and accumulated on the rolling surface of the rolling wheel 42 during the rolling process of the rolling wheel 42.

[0051] Further, the rolling direction of the rolling wheel 42 is consistent with the advancing direction of the handcart 1, and the rolling wheels 42 are arranged along the advancing direction of the handcart 1.

[0052] The material supplement scraping device 41 is arranged between two adjacent rolling wheels 42 and is provided with scraping members 411 on both sides for being close to the rolling surfaces of the two adjacent rolling wheels 42.

[0053] In the embodiment, when a plurality of rolling wheels 42 are arranged, the rolling direction of the rolling wheel 42 is preferably consistent with the advancing direction of the handcart 1, and the rolling wheels 42 are arranged along the advancing direction of the handcart 1. After the handcart 1 advances back and forth to fill the material supplement, the rolling wheels 42 are compacted, which improves the compaction efficiency. Based on this, the material supplement scraping device 41 is preferably arranged between two adjacent rolling wheels 42 and is provided with scraping members 411 on both sides for being close to the rolling surfaces of the two adjacent rolling wheels 42, so that one material supplement scraping device 41 can scrape the material supplement of two rolling wheels 42, and the number of material supplement scraping devices 41 can be reduced.

[0054] Further, the material supplement pushing member 2 is a stirring device, and the stirring device is arranged at the top of the material supplement containing cavity 13, and the stirring member of the stirring device extends downward to the inner side of the discharge port 12.

[0058] Further, the bottom of the discharge port 12 and the rear end of the material supplement guide plate 125 are connected in an up-down rotating manner.

[0059] In the embodiment, the feeding guide plate 125 is arranged in a rotatable manner, and the inclination of the feeding guide plate 125 can be adjusted according to the construction condition and the viscosity of the asphalt feeding, so as to facilitate the feeding.

[0060] Further, the bottom surface of the feeding accommodating cavity 13 is an inclined slide from the feeding opening 11 to the discharging opening 12.

[0061] In the embodiment, the feeding guide plate 125 is rotatable, and the feeding guide plate 125 can be rotated upward to block the feeding opening 14 when the feeding is not needed; the bottom surface of the feeding accommodating cavity 13 is an inclined slide from the feeding opening 11 to the discharging opening 12, so that the feeding speed is faster when the feeding is needed, and the feeding can be blocked by the feeding guide plate 125 when the feeding is not needed, thereby avoiding the leakage of the feeding.
