Technical Field

[0001] This utility model relates to the technical field of bridge deck paving equipment, and more specifically, to an automatic material feeding paver for bridge deck paving. Background Technology

[0002] In the field of bridge deck paving construction, with the continuous expansion of the scale of transportation infrastructure construction and the strict requirements for quality, higher standards have been put forward for the performance of bridge deck paving equipment.

[0003] The existing publication number CN215441322U discloses an automated asphalt paver, relating to the field of asphalt paving technology. It includes a mobile trolley, a spraying assembly, a uniform material distribution assembly, a leveling device, and a compaction assembly. The mobile trolley is capable of automatic movement, and the spraying assembly is mounted on one side of the mobile trolley. Through the cooperation of these components, the paver can automatically spray, uniformly distribute, level, and compact the road surface, replacing manual labor and improving efficiency. In the process of realizing this utility model, the inventors discovered the following problems with the existing technology:

[0004] Existing equipment often uses relatively simple feeding methods. In actual operation, it is difficult to dynamically adjust the material supply based on the real-time remaining amount in the material bin, which can easily lead to oversupply and accumulation. This not only wastes materials but also reduces construction efficiency. The existing leveling devices have a relatively simple structure and are not adaptable to complex bridge terrain. When facing bridge surfaces with different slopes and undulations, it is difficult to achieve uniform and precise leveling operations, resulting in poor flatness of the paved bridge surface, which affects the overall quality of the bridge and driving comfort.

[0005] Therefore, an automatic material feeding paver for bridge deck paving is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic material feeding paver for bridge deck paving to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic material feeding paver for bridge deck paving, comprising a material holding box, the inside of which has a discharge port, a motor fixedly mounted on one side of the material holding box via a detachable installation method, the output end of the motor being connected to a rotating shaft, a screw rod located on one side of the rotating shaft, the screw rod being located inside the discharge port, the screw rod rotating as the rotating shaft rotates, a fixing plate fixedly mounted on one side of the material holding box, a threaded hole being provided above the fixing plate, a rotating screw rod vertically mounted on the upper side of the fixing plate, the rotating screw rod passing through the threaded hole, a support frame fixedly placed at the bottom of the rotating screw, rotating rods fixedly mounted at both ends inside the support frame, a leveling roller rod movably mounted on the outer side of the rotating rod, the leveling roller rod being able to rotate flexibly on the rotating rod, and a handle fixedly mounted on one side of the material holding box.

[0008] Preferably, the rotating shaft penetrates one side wall of the material container, and after penetrating the material container, the rotating shaft continues to extend, with its end reaching the interior of the discharge port, within the space of the discharge port.

[0009] Preferably, positioning frames are symmetrically fixedly installed on the left and right sides of the material container, and a lifting screw is threadedly installed on the top of the positioning frame. The bottom of the lifting screw is fixedly connected to a wheel frame by welding, and the wheel frame has a detachable structure for installing movable wheels.

[0010] Preferably, a rotating nut is threaded on the outer side of the lifting screw, the rotating nut is matched with the lifting screw, and the rotating nut is installed directly above the positioning frame. When the rotating nut is rotated, the lifting screw moves up and down under the constraint of the positioning frame.

[0011] Preferably, a positioning plate is detachably placed at the bottom of the material container, and a separation rod is fixedly installed at the bottom of the positioning plate by welding.

[0012] Preferably, the bottom of the positioning plate has a screw hole that matches the fastening bolt. The fastening bolt is fixed by threaded installation. When installing the positioning plate, the positioning plate is placed at the corresponding position at the bottom of the material box. As the fastening bolt is screwed in, the top of the fastening bolt will abut against the bottom of the material box.

[0013] Preferably, the bottom of the rotating screw is detachably mounted with a bearing, which is positioned above the support frame. In the installed state, the inner ring of the bearing is in contact with and engaged with the outer side of the rotating screw.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Compared with existing technologies, this automatic material feeding paver for bridge deck paving uses a motor to drive a rotating shaft and a screw rod located in the material inlet. The rotation of the screw rod achieves uniform material feeding, making the feeding process highly controllable. It can precisely control the speed and amount of material falling according to actual construction needs, avoiding material accumulation or insufficient supply, greatly improving the accuracy and efficiency of feeding, ensuring the continuity of construction, and reducing material waste.

[0016] Compared with existing technologies, this automatic material feeding paver for bridge deck paving allows for flexible adjustment of the height of the support frame via a rotating screw passing through a threaded hole in the fixed plate. This, in turn, adjusts the contact position between the leveling roller and the bridge deck. The leveling roller rotates flexibly on the rotating rod, conforming to the bridge deck. As the paver moves, it rolls and levels the paving material, making the leveling operation more precise. It can adapt to bridge decks with different slopes and undulations, effectively improving the flatness of the bridge deck and enhancing the quality of bridge deck paving. Attached Figure Description

[0022] Example 1

[0023] As attached Figures 1 to 3The automatic material feeding paver for bridge deck paving shown includes a material container 1, with a discharge port 2 inside the material container 1. A motor 3 is detachably fixed to one side of the material container 1, and the output end of the motor 3 is connected to a rotating shaft 4. A screw rod 5 is provided on one side of the rotating shaft 4, and the screw rod 5 is located inside the discharge port 2. As the rotating shaft 4 rotates, the screw rod 5 also rotates. A fixing plate 14 is fixedly installed on one side of the material container 1, and a threaded hole 15 is provided on the upper part of the fixing plate 14. A rotating screw 16 is vertically arranged on the upper side of the fixing plate 14, and the rotating screw 16 passes through the threaded hole 15. A support frame 18 is fixedly placed at the bottom of the rotating screw 16. Rotating rods 19 are fixedly installed at both ends inside the support frame 18. A leveling roller 20 is movably installed on the outer side of the rotating rod 19, and the leveling roller 20 can rotate flexibly on the rotating rod 19. A handle 21 is also fixedly installed on one side of the material container 1.

[0024] Among them: a motor 3 can be detachably installed on one side of the material container 1, which facilitates the maintenance and replacement of the motor 3 and reduces maintenance costs; the output end of the motor 3 is connected to the rotating shaft 4, and the screw rod 5 on one side of the rotating shaft 4 is located in the material discharge port 2. It rotates with the rotating shaft 4 to achieve uniform and stable material discharge, ensuring the continuity and uniformity of the paving material supply; next, the rotating screw 16 vertically set on the upper side of the fixed plate 14 passes through the threaded hole 15, and the bottom of the rotating screw 16 is fixed to the bearing frame 18. The leveling roller 20 is movably installed on the outside of the rotating rod 19 inside the bearing frame 18. The leveling roller 20 can rotate flexibly and can effectively level the paving material, improving the flatness of the bridge deck paving; secondly, the handle 21 fixedly installed on one side of the material container 1 makes it convenient for operators to move and adjust the position of the paver, improving the convenience and flexibility of construction, and helping to improve the overall construction efficiency and quality.

[0025] Example 2

[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 3 As shown below, see details:

[0027] In a preferred embodiment, the rotating shaft 4 penetrates one side wall of the material container 1, ensuring that the rotating shaft 4 is stable during operation and will not shake or deviate. After penetrating the material container 1, the rotating shaft 4 continues to extend, and the end of the rotating shaft 4 reaches the interior of the discharge port 2. In the space of the discharge port 2, the rotating shaft 4 works in coordination with components such as the screw rod 5. When the rotating shaft 4 rotates under the drive of the motor 3, it can drive the relevant components to work in an orderly manner, thereby realizing a stable, uniform and controllable conveying and discharging process of materials in the discharge port 2.

[0028] In a preferred embodiment, positioning frames 6 are symmetrically fixedly installed on the left and right sides of the material container 1. The positioning frames 6 are made of high-strength materials to provide reliable support for subsequent components. A lifting screw 7 is installed on the top of the positioning frame 6 by thread. This threaded connection method not only ensures the stability of the connection, but also facilitates the adjustment of the lifting screw 7. The bottom of the lifting screw 7 is fixedly connected to the wheel frame 8 by welding. The wheel frame 8 has a detachable structure with movable wheels 9 installed inside, so that when the movable wheels 9 are worn or damaged, they can be easily and quickly replaced and repaired, ensuring the mobility of the material container 1.

[0029] In a preferred embodiment, a rotating nut 10 is threaded onto the outer side of the lifting screw 7. The rotating nut 10 matches the lifting screw 7 to ensure engagement and smooth rotation during rotation. The rotating nut 10 is installed directly above the positioning frame 6. Its position has been carefully measured and adjusted so that it will not affect the fit with the lifting screw 7 due to positional deviation, and it also allows the operator to directly rotate it. When the rotating nut 10 is rotated, the lifting screw 7 moves up and down under the constraint of the positioning frame 6, thereby realizing the height adjustment function of the components connected to the lifting screw 7.

[0030] As a preferred embodiment, a positioning plate 11 is detachably placed at the bottom of the material container 1. The positioning plate 11 is made of a sturdy and durable material to ensure its stability during use. A separation rod 13 is fixedly installed at the bottom of the positioning plate 11 by welding. The separation rod 13 can effectively separate the material during the material feeding operation of the material container 1 to prevent the material from sticking together and improve the feeding effect.

[0031] In a preferred embodiment, the bottom of the positioning plate 11 is provided with screw holes that are compatible with the fastening bolts 12. The fastening bolts 12 are fixed by threaded installation. These fastening bolts 12 are reasonably distributed and the number is determined according to the positioning requirements to ensure uniform force. When installing the positioning plate 11, the positioning plate 11 is placed at the corresponding position at the bottom of the material container 1. As the fastening bolts 12 are continuously screwed in, the top of the fastening bolts 12 will abut against the bottom of the material container 1. By utilizing the friction between the two and the biting force of the threads, the positioning plate 11 and the material container 1 are accurately positioned, effectively preventing the positioning plate 11 from loosening or shifting during use.

[0032] In a preferred embodiment, the bottom of the rotating screw 16 is detachably equipped with a bearing 17, which facilitates subsequent maintenance and replacement. When the bearing 17 is worn or malfunctions, it can be removed for repair or replacement without complicated operations. The bearing 17 is positioned above the support frame 18, and its position is precisely measured and adjusted to ensure stability and functionality. In the installed state, the inner ring of the bearing 17 fits against the outer side of the rotating screw 16, and the two are in contact and cooperate with each other. When the rotating screw 16 rotates, the bearing 17 can provide smooth support and rotation guarantee, reduce friction and wear, and ensure the smooth operation of the entire device.

[0033] In this embodiment, the motor 3 and the movable wheel 9 are commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, and we will not go into detail here.

[0034] The working process of this utility model is as follows: First, rotate the rotating nut 10 that matches the lifting screw 7 directly above the positioning frame 6. Since the rotating nut 10 is positioned and threadedly engaged with the lifting screw 7, under the constraint of the positioning frame 6, the lifting screw 7 drives the wheel frame 8 welded at the bottom and the internally detachable movable wheel 9 to move downwards, so that the movable wheel 9 touches the ground, pushes the handle 21 fixed on one side of the material box 1, and moves the paver to the bridge deck construction position. After arriving, rotate the rotating nut 10 in the opposite direction to raise the movable wheel 9 and let the material box 1 contact the bridge deck.

[0035] Next, place the positioning plate 11, which has screw holes at the bottom that are compatible with the fastening bolts 12, at the corresponding position at the bottom of the material box 1, and screw in the fastening bolts 12 so that its top end abuts against the bottom of the material box 1 to complete the installation of the positioning plate 11. The separation rod 13 welded to the bottom of the positioning plate 11 can be used for auxiliary positioning and other work.

[0036] Next, the bridge deck paving material is loaded into the material container 1. The motor 3, which is fixed to one side of the material container 1 in a detachable manner, is started. Its output end drives the connected rotating shaft 4 to rotate. The rotating shaft 4 passes through the wall of the material container 1 and extends into the space of the internal discharge port 2. The rotating shaft 4 drives the spiral rod 5 located in the discharge port 2 on one side to rotate.

[0037] Finally, the rotating screw 16, vertically mounted on the fixed plate 14 on one side of the material container 1 and passing through the threaded hole 15, is rotated. The support frame 18, mounted on the bottom of the rotating screw 16 via a detachable bearing 17, moves up and down accordingly. This adjusts the leveling roller 20, movably mounted on the outer side of the rotating rods 19 fixed at both ends inside the support frame 18, to contact the bridge deck. As the screw 5 rotates, the material is fed and paved. The leveling roller 20 rotates flexibly on the rotating rods 19 to achieve leveling. The above describes the working principle of this automatic bridge deck paving machine.
