Description

Technical Field

[0001] This utility model relates to the field of paver technology, specifically to a paver used for laying thick, one-pass, whole-width water-stabilized base courses. Background Technology

[0002] A paver is a construction device mainly used for paving various materials for the base and surface layers of highways. A paver can evenly spread crushed stone or asphalt concrete on the roadbed and perform preliminary compaction and leveling. The paver consists of a vehicle body, with a paver mounted on the front and a conveyor seat on the rear. The top of the conveyor seat has a sluice gate, and below the sluice gate is a conveying device that transports materials to the paver. A hopper is located above the conveyor seat.

[0003] Currently, during paver operation, material is dumped onto the paver's hopper by a material truck, falls through the sluice gate, and is then transported to the paver by a conveyor. However, a lot of material often accumulates around the sluice gate in the hopper, which indirectly reduces the hopper's capacity and affects subsequent material replenishment. Currently, the residual material is usually shoveled off manually, but this method is inefficient and affects overall construction efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model proposes a paver for laying thick, one-pass, whole-width water-stabilized base courses to solve the above problems.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] The paver provided by this utility model for laying a thick, one-pass, whole-width water-stabilized base course includes a vehicle body, a paver mounted on the front side and a conveyor seat mounted on the rear side, the top of the conveyor seat having a sluice gate and a conveying device for conveying materials to the paver being installed below the sluice gate, and further includes:

[0007] The hopper mechanism includes receiving plates and first hydraulic cylinders. The two receiving plates are rotatably mounted on the top two sides of the conveyor seat. The ends of the two receiving plates that are away from each other extend out of the outer side of the conveyor seat and are provided with side baffles. The two first hydraulic cylinders are rotatably mounted on the two sides of the conveyor seat, and the telescopic shaft ends of the first hydraulic cylinders are rotatably connected to the bottom side of the corresponding receiving plate.

[0008] The feeding mechanism includes a pusher plate and two hydraulic cylinders. The two hydraulic cylinders are respectively installed on both sides of the conveyor seat. The telescopic shaft end of the second hydraulic cylinder faces the rear side of the vehicle body and is provided with a connecting block. The pusher plate is located at the top rear end of the conveyor seat and is connected to the two connecting blocks. The second hydraulic cylinder can drive the pusher plate to move into or out of the upper side of the two receiving plates.

[0009] Furthermore, the push plate can abut against the top surface of the receiving plate, and connecting plates that can abut against the inner surface of the side baffle are respectively provided on the top two sides of the push plate.

[0010] Furthermore, a slider is installed at the bottom of the push plate, and the slider is slidably mounted on the top of the conveyor seat.

[0011] Furthermore, a tilting plate is rotatably mounted on the top surface of the push plate near the receiving plate, a rack is provided on the top of the conveyor seat, a drive groove is provided on the push plate, a gear that meshes with the rack is rotatably mounted in the drive groove, and a protrusion is provided on the edge of the gear. When the push plate moves into the upper part of the receiving plate, the protrusion can rotate to lift the guide plate.

[0012] Furthermore, an abutment wheel is installed on the protrusion.

[0013] As can be seen from the above technical solution, the paver provided by this utility model for paving a thick, one-pass, full-width water-stabilized base course is:

[0014] After the conveying device has transferred the material that has fallen into the trough, the two first hydraulic cylinders are activated to extend and retract their telescopic shafts, causing the receiving plate to rotate and tilt towards the trough to pour the remaining material into the trough before returning to its original position. Then, the second hydraulic cylinder is activated to retract and extend its telescopic shaft, causing the pusher plate to push the material on the upper side of the receiving plate to push it to the top of the trough and the top of the receiving plates on both sides before returning to its original position. Finally, the two first hydraulic cylinders are activated again to extend and retract their telescopic shafts, which can pour the material transferred by the pusher plate back into the trough, thus emptying most of the remaining material into the trough. This replaces manual shoveling, which helps improve construction efficiency and ensures sufficient material holding space. Attached Figure Description

[0023] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] like Figure 1-3 As shown, the paver provided in this embodiment for paving a thick, single-width, water-stabilized base course includes a vehicle body 1, with a paver 11 mounted on its front side and a conveyor seat 12 mounted on its rear side. A trough 121 is formed on the top of the conveyor seat 12, and a conveying device 13 capable of conveying materials to the paver 11 is installed below the trough 121. Since the paver is prior art equipment, its specific structure will not be described in detail here. The paver for paving a thick, single-width, water-stabilized base course also includes a hopper mechanism 2 and a replenishment mechanism 3.

[0027] The hopper mechanism 2 includes receiving plates 21 and first hydraulic cylinders 22. Two receiving plates 21 are rotatably mounted on the top sides of the conveyor seat 12. The ends of the two receiving plates 21 that are furthest from each other extend outwards from the outer side of the conveyor seat 12 and are equipped with side baffles 211. The side baffles 211 extend upwards to form side enclosures. Two first hydraulic cylinders 22 are rotatably mounted on both sides of the conveyor seat 12, and the telescopic shaft ends of the first hydraulic cylinders 22 are rotatably connected to the bottom side of the corresponding receiving plate 21. By driving the telescopic shafts of the first hydraulic cylinders 22 to extend or retract, the receiving plates 21 can be driven to rotate towards or away from the trough 121, thereby pouring the residual material on the receiving plates 21 into the trough 121.

[0028] The feeding mechanism 3 includes a pusher plate 31 and a second hydraulic cylinder 32. The two second hydraulic cylinders 32 are respectively installed on both sides of the conveyor seat 12. The telescopic shaft end of the second hydraulic cylinder 32 faces the rear side of the vehicle body 1 and is provided with a connecting block 321. The pusher plate 31 is located at the top rear end of the conveyor seat 12 and is connected to the two connecting blocks 321. The pusher plate 31 can receive the material located behind the trough 121. The second hydraulic cylinder 32 can drive the pusher plate 31 to move into or out of the upper side of the two receiving plates 21, so as to push the material located behind the trough 121 to the top of the trough 121 and the top of the receiving plates 21 on both sides.

[0029] In practical use, after the conveying device 13 has finished transferring the material that has fallen into the trough 121, the two first hydraulic cylinders 22 are activated to extend and retract their telescopic shafts, causing the receiving plate 21 to rotate and tilt towards the trough 121 to pour the remaining material on it into the trough 121 and then return to its original position. Then, the second hydraulic cylinder 32 is activated to retract and extend its telescopic shafts, causing the pusher plate 31 to push the material on it to the top of the trough 121 and the top of the receiving plates 21 on both sides, and then return to its original position. Finally, the two first hydraulic cylinders 22 are activated again to extend and retract their telescopic shafts, so that the material transferred by the pusher plate 31 can be poured back into the trough 121, so that most of the remaining material can be poured into the trough 121, replacing manual shoveling, which helps to improve construction efficiency and ensures sufficient material holding space.

[0030] Preferably, the push plate 31 can abut against the top surface of the receiving plate 21, and the top two sides of the push plate 31 are respectively provided with connecting plates 311 that can abut against the inner side of the side baffle 211, so that when the push plate 31 moves into the upper side of the receiving plate 21, it can fit tightly against the surfaces of the receiving plate 21 and the side baffle 211, preventing the push plate 31 from carrying out materials during the movement.

[0031] Furthermore, such as Figure 2As shown, a slider 312 is installed at the bottom of the push plate 31, and a slide rail is provided at the top of the conveyor seat 12 behind the trough 121. The slider 312 is slidably installed on the top of the conveyor seat 12 via the slide rail. The slider 312 not only makes the movement of the push plate 31 smoother, but also lifts the push plate 31 to better fit the surfaces of the receiving plate 21 and the side baffle 211. It should be noted that the slider 312 should be installed on the bottom side of the push plate 31 away from the receiving plate 21 to prevent the slider 312 from interfering with the connection between the push plate 31 and the receiving plate 21.

[0032] In one embodiment, a guide plate 313 is rotatably mounted on the top surface of the push plate 31 near the receiving plate 21. A rack 122 is provided on the top of the conveying seat 12. A drive groove 314 is provided on the push plate 31. A gear 315 that meshes with the rack 122 is rotatably mounted in the drive groove 314. A protrusion 3151 is provided on the edge of the gear 315. When the push plate 31 moves into the upper side of the receiving plate 21, the gear 315 will mesh with the rack 122 and rotate, so that the protrusion 3151 can rotate and deflect towards the top of the drive groove 314, thereby lifting the guide plate 313 and tilting the guide plate 313, so that the material on it can slide along the slope to the top of the trough 121 and the top of the receiving plates 21 on both sides.

[0033] Preferably, the protrusion 3151 is equipped with an abutment wheel 3152, which can make the abutment wheel 3152 contact the ground of the guide plate 313 when the protrusion 3151 rotates, thereby reducing the wear on the guide plate 313.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of this utility model, and they should all be covered within the scope of the claims and description of this utility model.
