Technical Field
[0001] The utility model relates to the technical field of road paver application, in particular to a working device for a paver. Background Art
[0002] A paver is a construction equipment used on roads, which is mainly used for paving various materials on the base and surface layers of the road surface. During the paving process of the paver, the main function of the ironing device is to perform initial compaction and ironing of the auxiliary materials in the paving chamber. As a component that directly paves the various layers of road surface materials in the paver, the performance of the ironing device is directly related to the quality of the paved road surface and is an extremely important part of the paver work.
[0003] At present, paving operations mainly face construction conditions that require variable road width. Therefore, the paving width of the paver must also change with demand. The ironing device can be extended to meet the paving width requirements, but the rear baffle of the auger is usually more complicated to drive, and it is difficult to achieve synchronous widening with the ironing device. As a result, not only the cost of construction operations is seriously increased, but also the efficiency of construction operations is seriously reduced, thereby further delaying the progress of construction.
[0004] Therefore, it is desired in the art to provide a working device for a paving machine to solve the above technical problems. Utility Model Content

[0012] In one embodiment, a limiting plate for abutting against the first adjusting plate is provided on the rear baffle plate of the auger.
[0013] In one embodiment, the adjustment assembly further comprises a second adjustment plate disposed below the first adjustment plate, and a plurality of limiting portions configured in a circular structure are arranged equidistantly in the transverse direction of the first adjustment plate.
[0014] A through hole configured to be an elliptical structure and adapted to the limiting portion is provided on the second adjusting plate, thereby allowing the second adjusting plate to move longitudinally relative to the first adjusting plate.

In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict.
[0031] The utility model will be further described below in conjunction with the accompanying drawings.

[0036] Figure 5 The figure schematically shows the lateral movement state of the auger tailgate mechanism 100 in the working device 200 for a paving machine according to the present invention.
[0037] like Figure 4 and 5 As shown, the working device 200 for a paver according to the utility model includes a first ironing frame 201 arranged on the paver (not shown), a second ironing frame 202 connected to the first ironing frame 201, and an auger rear baffle mechanism 100 arranged on the second ironing frame 202.
[0038] In the utility model, since the second ironing frame 202 can slide laterally relative to the first ironing frame 201, the auger rear baffle mechanism 100 fixed on the second ironing frame 202 can also be automatically adjusted following the second ironing frame 202 to achieve the purpose of adjusting the amplitude of the auger rear baffle 10 and changing the width of the paver operation.
[0039] The utility model replaces manual disassembly with automatic adjustment, which not only significantly reduces the cost of construction work, but also improves the efficiency of construction work and ensures good overall paving quality, thereby further shortening the construction progress.
[0040] In one embodiment, Figure 1 , 4 As shown in Figures 5 and 6, the working device 200 for the paving machine further includes a guide rod 203 arranged laterally on the first screed frame 201 and the second screed frame 202. Preferably, the auger rear baffle mechanism 100 includes a guide sleeve 50 sleeved on the outside of the guide rod 203, so that the auger rear baffle 10 (described below) can be adjusted to slide on the guide rod 203 through the guide sleeve 50, thereby limiting the lateral movement stroke of the auger rear baffle 10.
[0041] In one embodiment, the guide sleeve 50 extends transversely and is embedded in the auger tailgate 10. Preferably, the guide sleeve 50 can be adapted to the guide rod 203 on the working device 200 of the paving machine to promote the auger tailgate 10 to achieve transverse movement.
[0042] like Figure 1 As shown, the auger rear baffle mechanism 100 includes an auger rear baffle 10 and an adjustment assembly. The adjustment assembly includes a first adjustment plate 21 spaced apart from the auger rear baffle 10, and at least two tension members disposed between the auger rear baffle 10 and the first adjustment plate 21. In the present utility model, the first adjustment plate 21 is configured to be able to perform lifting motion relative to the auger rear baffle 10 under the action of the tension members.
[0043] In one embodiment, Figure 1 As shown, a first fixing seat 11 is provided on the rear baffle plate 10 of the auger. In addition, the stretching member includes an adjuster 31 adapted to the first fixing seat 11, and an adjusting rod 32 adapted to the adjuster 31. Preferably, the adjusting rod 32 can smoothly perform axial reciprocating motion (i.e., prompt the first adjusting plate 21 to perform lifting motion) under the action of the adjuster 31, thereby achieving the purpose of adjusting the overall height of the rear baffle plate mechanism 100 of the auger.
[0044] In the present invention, the stretching member is, for example, a matching form of a piston and a piston rod or a matching form of a long screw manually adjusted.
[0045] According to the utility model, the adjustment assembly further includes slideways arranged on both sides of the auger rear baffle 10. Preferably, the slideways are configured as long strips and are arranged longitudinally on the auger rear baffle 10. Accordingly, a slide rail (not shown) adapted to the slideway is provided on the first adjustment plate 21, so that the first adjustment plate 21 can form a sliding connection with the auger rear baffle 10 under the action of the slide rail and the slideway.
[0046] In other words, the first adjustment plate 21 can move longitudinally relative to the auger rear baffle 10 to adjust the height of the lower edge of the auger rear baffle 10 and the overall height of the auger rear baffle mechanism 100, thereby accurately controlling the feed amount.
[0047] In one embodiment, Figure 1 As shown, the free end of the adjusting rod 32 is fixed on the first adjusting plate 21 through a mounting plate 33 .
[0048] Combination Figure 2 and 3 The longitudinal displacement of the first adjustment plate 21 relative to the rear baffle plate 10 of the auger is described as follows:
[0049] Preferably, when the height of the lower edge of the auger rear baffle 10 needs to be increased, the adjusting rod 32 moves axially downward under the action of the adjuster 31, thereby causing the first adjusting plate 21 to move downward relative to the auger rear baffle 10, so as to achieve the purpose of increasing the overall height of the auger rear baffle mechanism 100.
[0050] Preferably, when it is necessary to reduce the height of the lower edge of the auger rear baffle 10, the adjusting rod 32 moves axially upward under the action of the adjuster 31, thereby causing the first adjusting plate 21 to move upward relative to the auger rear baffle 10, so as to achieve the purpose of reducing the overall height of the auger rear baffle mechanism 100.
[0051] In one embodiment, the adjustment assembly further includes a plurality of spaced apart stoppers. Figure 1 As shown, the limiting member includes a limiting seat 41 and a limiting rod 42 fixed in the limiting seat 41. Preferably, the limiting rod 42 abuts against the first adjustment plate 21 radially, thereby effectively limiting the first adjustment plate 21 in the horizontal direction to ensure that the first adjustment plate 21 can only move in the longitudinal direction.
[0052] Preferably, a second fixing seat 12 adapted to the limiting seat 41 is provided on the rear baffle 10 of the auger. Accordingly, the second fixing seat 12 is configured to be axially abutted against the first adjustment plate 21, thereby effectively limiting the longitudinal movement of the first adjustment plate 21.
[0053] In one embodiment, Figure 1 As shown, a limit plate 14 is provided on the rear baffle 10 of the auger. Preferably, when the first adjustment plate 21 moves to the highest point, it can abut against the limit plate 14, thereby limiting the movement stroke of the first adjustment plate 21. In this practicality, the limit plate 14 and the limit member work together to ensure that the first adjustment plate 21 can always slide in an orderly manner on the prescribed path.
[0054] According to the utility model, if Figure 1As shown, the auger rear baffle mechanism 100 further includes a shield 60 located above the first adjustment plate 21. Preferably, the shield 60 is configured to be fixed to the auger rear baffle 10 by a bayonet, thereby playing the role of closing the regulator 31. As a result, the regulator 31 is fully protected under the action of the shield 60, so as to improve the service life of the auger rear baffle mechanism 100.
[0055] In one embodiment, Figure 1 As shown, the adjustment assembly further includes a second adjustment plate 22 disposed below the first adjustment plate 21. Preferably, a plurality of limit portions 211 are arranged equidistantly in the transverse direction of the first adjustment plate 21, and the plurality of limit portions 211 are configured into a circular structure.
[0056] In one embodiment, Figure 1 As shown, the second adjustment plate 22 is provided with a through hole 221 configured in an elliptical structure adapted to the limiting portion 211 , and the length direction of each through hole 221 is parallel to the longitudinal direction, thereby allowing the second adjustment plate 22 to move longitudinally relative to the first adjustment plate 21 .
[0057] In the utility model, by adjusting the longitudinal position of the second adjustment plate 22 relative to the first adjustment plate 21, the lower edge height of the rear baffle 10 of the auger can be further adjusted to achieve precise control of the feed amount, thereby adapting to more different construction conditions, and further improving the paving quality of the working device 200 for the paver.
[0058] Compared with the prior art, the advantages of the present invention are:
[0059] First, the second ironing frame 202 in the utility model can slide laterally relative to the first ironing frame 201, and since the auger rear baffle mechanism 100 is fixedly installed on the second ironing frame 202, the auger rear baffle mechanism 100 can move synchronously with the second ironing frame 202 to achieve the purpose of adjusting the amplitude of the auger rear baffle 10 and changing the width of the paver operation.
[0060] In addition, in the present invention, a guide sleeve 50 and a guide rod 203 are respectively provided, so as to effectively guide the movement direction of the first ironing frame 201 to ensure that the working device 200 for the paving machine can run smoothly.
[0061] In addition, the utility model replaces manual disassembly with automatic adjustment, which not only significantly reduces the cost of construction work, but also improves the efficiency of construction work and ensures good overall paving quality, thereby further shortening the construction progress.
[0062] Secondly, the utility model uses the adjusting rod 32 and the adjusting device 31 in combination, so that the first adjusting plate 21 can be longitudinally displaced relative to the auger rear baffle 10, so as to achieve the purpose of adjusting the overall height of the auger rear baffle mechanism 100. Specifically, when it is necessary to change the height of the lower edge of the auger rear baffle 10, the adjusting rod 32 moves axially upward or downward under the action of the adjusting device 31, so as to cause the first adjusting plate 21 to move downward or upward relative to the auger rear baffle 10, so as to achieve the purpose of adjusting the overall height of the auger rear baffle mechanism 100.
