Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a concrete paving device. Background Art

[0002] Concrete is a general term for engineering composite materials that are made by cementing aggregates into a whole. Concrete usually refers to cement as the cementing material, sand and stone as aggregates, mixed with water in a certain proportion, and may also contain admixtures and additives. The cement concrete obtained by mixing is used for road base paving.

[0003] During the construction process of the road base, concrete needs to be spread to make it smoother. The paving device in the prior art mainly includes a frame and a paving roller arranged under the frame. The paving roller moves on the casting formwork while spreading the concrete between the two casting formworks. For example, the patent document with application number 202321101173.3 discloses a road paving device. When in use, by applying tension to the traction frame, the walking wheel drives the support seat and the storage tank to move forward, thereby driving the paving pipe to move, and the concrete flows out of the paving pipe. Then, the pressure roller levels the paved concrete, thereby improving the paving quality and saving labor costs. However, in actual application, the inventor noticed that the above solution has some defects: when the concrete is discharged from the inside of the storage tank along the paving pipe to the ground, the concrete is piled together and does not disperse. When the pressure roller is used to level the concrete later, it has the disadvantage of being difficult to pave, which is difficult to meet the use requirements. Therefore, a concrete paving device is proposed to address the above problems. Summary of the Invention

[0029] Please refer again Figure 3 The driving mechanism includes a housing 8 and two sprockets 9 rotatably arranged in the housing 8. The two sprockets 9 are connected by a chain 10. A boss 11 is rotatably provided on the chain 10. A sliding plate 12 is provided on one side of the chain 10. A long slot 13 is vertically opened on the sliding plate 12, and the boss 11 is located in the long slot 13; a straight rod 14 is provided in the housing 8, and a circular hole is opened on the sliding plate 12. The circular hole is located below the long slot 13, and the straight rod 14 is sleeved in the circular hole.

[0030] Specifically, the sliding plate 12 passes through the opening at the bottom of the shell 8, and the part of the sliding plate 12 located outside the shell 8 is provided with a mounting hole. The feed pipe 5 is installed in the mounting hole, and the boss 11 is driven to move by the rotation of the chain 10, thereby moving the sliding plate 12. When the sliding plate 12 moves to both ends of the chain 10, the boss 11 slides in the long groove 13, and then the chain 10 drives the boss 11 to move in the opposite direction, thereby achieving the purpose of the sliding plate 12 to make reciprocating linear motion along the straight rod 14, and finally driving the feed pipe 5 installed on the sliding plate 12 to swing back and forth, so that the concrete is dispersed and flows to the ground.

[0031] In addition, a rotating shaft is provided at the center of each sprocket 9, and a portion of the rotating shaft of one sprocket 9 located outside the housing 8 is connected to a motor 15, which provides power for the rotation of the sprocket 9 and the chain 10.

A plurality of notches are opened at the bottom end of the vertical plate 61. The notches can facilitate the passage of part of the concrete.

[0033] In this embodiment, the adjustment mechanism is connected to the horizontal plate 62. The adjustment mechanism includes a support plate 16 arranged on the frame 1 and a screw rod 17 rotatably arranged on the support plate 16. The screw rod 17 is located on one side of the vertical plate 61. Two guide rods 18 are provided on the other side of the vertical plate 61. Threaded holes and through holes are provided on the horizontal plate 62. The threaded holes cooperate with the screw rod 17. The two guide rods 18 are respectively passed through the corresponding through holes.

On the one hand, it can reduce the resistance of the scraper 6, and on the other hand, it can ensure that the pressure roller 7 has a better paving effect.

[0037] The working principle of this utility model is:

[0038] During the movement of the frame 1, the concrete in the box 2 is discharged from the feed pipe 5. At the same time, the sliding plate 12 in the driving mechanism makes a reciprocating linear motion along the straight rod 14, thereby driving the feed pipe 5 installed on the sliding plate 12 to swing back and forth, so that the concrete is dispersed and flows to the ground, which is convenient for the construction workers to carry out paving operations. Subsequently, when paving the concrete, the scraper 6 is set so that the concrete can be scraped flat in advance, thereby facilitating the operation of the pressure roller 7. Furthermore, a notch is set on the vertical plate 61 of the scraper 6 to facilitate the passage of part of the concrete. On the one hand, it can reduce the resistance of the scraper 6, and on the other hand, it can ensure that the pressure roller 7 has a better paving effect. Finally, the pressure roller 7 compacts and flattens the concrete, thereby improving the paving quality.
