Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a auger width adjustment device for a paver. Background Art

[0002] A paver is a construction equipment mainly used for paving various materials on the base and surface layers of highways. The paving work is completed by various systems working together. The paving width of a conventional paver is fixed, and its paving width mainly depends on the width of the paver's auger. The width of the auger cannot be freely adjusted. Therefore, a paver that cannot freely adjust the paving width has certain limitations when paving on projects with different working widths.

[0003] In order to make the paving width of the paver adapt to projects with different working widths, the paver in the prior art is shown in the Chinese utility model with patent number CN201920963445.8 (authorization announcement number CN210420787U). The paving box body is provided with a spiral distributor composed of spiral blades. By arranging pluggable shielding baffles on both sides of the center of the paving box body, the paving width of the slurry entering the center of the paving box can be adjusted to adapt to ruts or troughs of different widths on the road, which effectively ensures its working efficiency and saves paving slurry.

[0004] Although the above-mentioned paver can adjust the paving width according to different road widths, the auger width adjustment device of the paver is mainly used for paving slurry materials, which have a small bulk density and belong to lightweight mixtures. Therefore, the existing paver adjusts the paving width through a pluggable baffle. However, in the actual paving process, the paver not only needs to pave lightweight mixtures, but also needs to pave stones and asphalt concrete, etc. The bulk density of such materials is generally greater than 2000kg / m 3 , which belongs to a large bulk density mixture. This type of material has poor fluidity and is difficult to spread evenly. In order to ensure the paving speed and paving uniformity of the paver paving the large bulk density mixture, a high-speed and high-torque auger is required to disperse the large bulk density mixture, but the large bulk density mixture also has a large reaction force on the auger. Therefore, when the paver is paving a large bulk density mixture, if it continues to use a pluggable baffle to adjust the paving width, the baffle will be squeezed by the large bulk density mixture, causing damage to the baffle, which will not only fail to adjust the paving width, but also affect the final paving effect. Further improvements are needed for this. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a auger width adjustment device for a paver suitable for paving a mixture with a large bulk density in view of the above-mentioned existing technical status.

[0006] The technical solution adopted by the utility model to solve the above-mentioned technical problems is as follows: the auger width adjustment device of the paver comprises a paving box, an auger for paving materials is provided in the paving box, and the characteristic is that: the paving box is also provided with a baffle for adjusting the paving width of the auger, and the baffle can be fixedly connected to the corresponding position of the inner wall of the paving box according to the required paving width, and the baffle is provided with a through hole for the auger to pass through, and the paving box is also provided with an adjustment part for adjusting the paving thickness.

[0007] In order to enhance the strength of the baffle plate fixed on the paving box, preferably, the baffle plate is welded to the inner wall of the paving box. Welding enhances the force of the baffle plate, so that the baffle plate can not only pave light mixtures, but also pave heavy mixtures.

[0008] Further, the adjusting member is a connecting plate arranged below the baffle, the top of the connecting plate is fixedly connected to the bottom of the baffle, and the two sides of the baffle are welded to the inner wall of the paving box. According to different paving thicknesses, a connecting plate of corresponding size is selected and fixedly installed at the bottom of the baffle.

[0009] Furthermore, at least two fixing holes are opened at the bottom of the baffle, and correspondingly, at least two connecting holes are opened at the top of the connecting plate, the connecting holes correspond to the fixing holes one by one, and the connecting parts pass through the corresponding connecting holes and fixing holes to fix the connecting plate and the baffle.

[0010] Preferably, the connecting member is a bolt.

[0011] In order to enable the paving material to be spread within the paving width fixed by the baffle, preferably, the baffle divides the space in the paving box into a paving area and a non-paving area. Correspondingly, the auger includes a paving section located in the paving area and a non-paving section located in the non-paving area. The paving section is used to spread the material. The non-paving section is sleeved with a fixed cylinder. The space in the fixed cylinder is cast with a building material that can be hardened. The building material forms a cylinder in the fixed cylinder. The rotation axis of the cylinder coincides with the rotation axis of the auger, thereby preventing the auger from polarizing; and the cylinder can block the blades of the non-paving section of the auger, so that when the auger rotates as a whole, the paving material will not enter the non-paving section along the blades of the auger paving section, thereby achieving the effect of controlling the paving width.

[0012] Furthermore, the building material is concrete. Concrete has the advantages of high strength and better economy, so concrete is used as a one-time building material to be poured in the fixed cylinder.

[0013] Furthermore, the diameter of the fixing tube is larger than the outer diameter of the auger blade.

[0014] In order to prevent the fixed cylinder from being stuck by the baffle when the auger rotates, preferably, the diameter of the fixed cylinder is smaller than the diameter of the through hole, and the radius difference between the through hole and the fixed cylinder is smaller than the particle size of the paving material.

[0015] Compared with the prior art, the advantages of the utility model are: by utilizing a baffle which can be fixedly connected to the corresponding position of the inner wall of the paving box according to the required paving width, the paving width of the auger can be adjusted according to different working widths; at the same time, since the baffle is fixedly connected to the inner wall of the paving box, the force of the baffle is enhanced, so that the baffle can not only pave lightweight mixtures, but also pave large bulk density mixtures, so that the application range of the auger width adjustment device of the paver is wider and the effect of adjusting the paving width is better.

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-5 Shown is the best embodiment of the utility model.

[0023] like Figure 1-3As shown, the auger width adjustment device of the paving machine in this embodiment includes a paving box 1, an auger 2, a baffle 3 and an adjusting member. The auger 2 for paving materials is arranged inside the paving box 1, and one end of the auger 2 is connected to a driving device (not shown in the figure) for driving it to rotate for paving materials, and the driving device is arranged outside the paving box 1; the paving box 1 is provided with a baffle 3 for adjusting the paving width of the auger 2 and an adjusting member for adjusting the paving thickness, and the baffle 3 can be welded to the corresponding position of the inner wall of the paving box 1 according to the required paving width, and the baffle 3 is provided with a through hole 31 for the auger 2 to pass through. And the baffle 3 divides the space in the paving box 1 into a paving area 11 and a non-paving area 12. Correspondingly, the auger 2 includes a paving section 21 located in the paving area 11 and a non-paving section 22 located in the non-paving area 12. The paving section 21 is used for paving materials, and a fixed cylinder 6 is sleeved on the non-paving section 22. The fixed cylinder 6 is made of iron sheet. The diameter of the fixed cylinder 6 is larger than the outer diameter of the blade of the auger 2, and the diameter of the fixed cylinder 6 is smaller than the diameter of the through hole 31. The radius difference between the through hole 31 and the fixed cylinder 6 is smaller than the particle size of the paving material, so that the fixed cylinder 6 is not stuck by the baffle 3 when the auger 2 rotates, and the paving material will not enter the non-paving area 12 along the gap between the through hole 31 and the fixed cylinder 6. In addition, the space in the fixed cylinder 6 is poured with concrete, which has the advantages of high strength and better economy. Therefore, concrete is used as a disposable building material to be poured in the fixed cylinder 6. The concrete forms a cylinder in the fixed tube 6, and the rotation axis of the cylinder coincides with the rotation axis of the auger 2, thereby preventing the auger 2 from polarizing; and the cylinder can block the blades of the non-paving section 22 of the auger 2, so that when the auger 2 rotates as a whole through the driving device, the paving material will not enter the non-paving section 22 along the blades of the paving section 21 of the auger 2, thereby achieving the effect of controlling the paving width.

[0024] like Figure 4 and Figure 5 As shown, the adjusting member is a connecting plate 4 arranged below the baffle 3, the top of the connecting plate 4 is fixedly connected to the bottom of the baffle 3, and the two sides of the baffle 3 are welded to the inner wall of the paving box 1. Among them, three fixing holes 32 are opened at the bottom of the baffle 3, and correspondingly, three connecting holes 41 are opened at the top of the connecting plate 4, and the connecting holes 41 correspond to the fixing holes 32 one by one. The bolts 5 pass through the corresponding connecting holes 41 and fixing holes 32 to fix the connecting plate 4 to the baffle 3.

[0025] The working principle of this embodiment is as follows: before use, according to the paving width of the working road, the baffle 3 is installed in the paving box 1, and the two side edges of the baffle 3 are welded to the inner wall of the paving box 1; then, according to the paving thickness of the working road, the connecting plate 4 of the corresponding size is selected, and the connecting plate 4 and the baffle 3 are fixedly connected by bolts 5 passing through the connecting hole 41 and the fixing hole 32; finally, the non-paving section 22 of the auger 2 is wrapped with a fixing cylinder 6, and concrete is poured into the fixing cylinder 6. It can be used only after the concrete hardens; when in use, the auger 2 starts to rotate as a whole through the driving device, the paving section 21 rotates in the paving area 11 to pave the corresponding width, and the non-paving section 22 rotates in the non-paving area 12. Since the non-paving section 22 is wrapped by the fixing cylinder 6 and concrete, the paving width of the paver is fixed.
