Description

Hopper device of paver

Technical Field

The utility model relates to a paver hopper device.

Background

The hopper device of the paver has the main function of receiving pavement paving raw materials dumped by a material conveying vehicle on the front side of the machine body, so that the paving ironing device on the rear side of the machine body provides raw materials and can play a role in balancing the center of gravity. The existing hopper device is hinged on a rack through a pin shaft, is connected with an oil cylinder through an oil cylinder mounting plate on the hopper, and can complete the opening and closing actions of the hopper at a certain angle through the driving of the oil cylinder, thereby realizing the function of spreading raw materials to the center of a storage bin.

In the process of opening and closing the hopper device, raw materials in the hopper easily overflow or spill out of the hopper. Therefore, a baffle structure is usually fixed to the front end of the hopper to reduce overflow and spillage of the raw material. However, in the existing hopper device, the baffle at the front end of the hopper is of a fixed structure, and cannot be matched with the opening and closing actions of the hopper to make matching actions. Therefore, the baffle plate has an unsatisfactory effect of reducing the overflow or spilling of raw materials, so that more raw materials are overflowed or spilled in the actual construction process. Therefore, the workload of workers for cleaning overflowing materials is increased, and a large amount of unnecessary raw materials are wasted.

In the present application, all the figures are schematic and are only intended to illustrate the principles of the present invention and are not drawn to scale.

Detailed Description

Fig. 1 shows a paver hopper apparatus 100 in accordance with one embodiment of the present disclosure. As shown in fig. 1, a paving machine hopper assembly 100 includes a frame 10 for attachment to a paving machine, the frame 10 having a bottom surface 15. A hopper 16 is also arranged on the frame 10, and the hopper 16 comprises a left hopper 20 and a right hopper 30 which are symmetrically arranged on two sides of the frame 10. The left and

right hoppers

20 and 30 have a horizontal plane parallel to the bottom surface 15 and a vertical plane perpendicular to the bottom surface 15, respectively. With this arrangement, the left and

right hoppers

20, 30 together with the frame 10 form a hollow housing 40 having a cavity 45, the cavity 45 being adapted to receive the material required for paving. A conveyor belt 18 is arranged on the bottom surface 15, which conveyor belt 18 is used to transport the raw material for paving to the ironing device of the paving machine.

Meanwhile, the left hopper 20 and the right hopper 30 are each hinged to the frame 10 by a first hinge pin 19 provided on the bottom surface 15. The first pin 19 is arranged in the longitudinal direction and is disposed on the inner side of the left and

right hoppers

20, 30 towards the bottom surface 15 so that the hopper 16 can be turned inwards at an angle around said first pin 19. In this way, material located within the hopper 16 can be more quickly poured onto the conveyor belt 18 by gravity as the hopper 16 is inverted.

To prevent the material in the cavity 45 from spilling out of the housing 40 when the hopper 16 is turned inside out, a central flap 50 is also provided on the bottom surface 15. The central flap 50 is articulated to the base 15 by a connecting shaft 55. The connecting shaft 55 is arranged in the transverse direction and is arranged on the inner side of the central flap 50 close to the bottom surface 15, so that the central flap 50 can be rotated relative to the bottom surface 15. When the hopper is not inverted, the central flap 50 is in the same plane as the bottom surface 15. With the turning of the hopper 16, the central turning plate 50 can be driven by the hopper 16 to rotate around the connecting shaft 55 toward the direction close to the bottom surface 15, and then gradually change from a horizontal state to a vertical state, so that the central turning plate 50 can block the raw materials from spilling. Also, the central flap 50 is preferably a rectangular baffle to ensure that it has the maximum blocking area. The movement of the hopper 16 to move the central flap 50 will be described in more detail below.

As shown in fig. 1, a side turning plate is further provided on each of the left hopper 20 and the right hopper 30. Hereinafter, the left flap 21 is described as an example where the left hopper 20 is provided.

In one aspect, the left flap 21 is hinged to the left hopper 20 by a second pin 22. The second pin 22 is arranged at the position where the left turning plate 21 and the left hopper 20 intersect, and is arranged in the same direction with the intersecting edge of the left turning plate and the left hopper. At the same time, the left flap 21 is located vertically above the central flap 50, so that the left flap 21 overlaps the central flap 50. Thus, when the central flap 50 rotates around the connecting shaft 55 in a direction approaching the bottom surface 15, the central flap 50 lifts the left flap 21 and rotates around the second pin 22. On the other hand, the left flap 21 is also turned towards the central flap 50 by the hopper 16. In the process, the left side flap 21 is gradually turned from the horizontal state to the vertical state, so that the left side flap 21 also serves to block the raw material in the cavity 45 from spilling.

As shown in fig. 1, a left seal 60 is also provided at the end of the left side flap 21 remote from the central flap 50. The left sealing element 60 is fixedly connected to the left hopper 20, and a contact surface 65 of the left sealing element and the left turning plate 21 is an inclined surface matched with the end surface of the left turning plate 21. In the process that the left turning plate 21 rotates around the second pin 22, the left turning plate 21 is always abutted against the contact surface 65, so that no gap exists between the left hopper 20 and the left turning plate 21, and the raw materials in the cavity 45 are prevented from spilling through the gap. Thus, the left seal 50 can perform a sealing function.

In addition, a left striker plate 26 is disposed on a side of the left flap 21 remote from the hopper 16. The left striker plate 26 may be a rectangular flat plate that is preferably perpendicular to the plane of the left side flap 21. When the left turning plate 21 is turned, the left material baffle 26 can be driven to turn together, so that the left material baffle 26 plays a role in auxiliary sealing, and the blocking effect of the left turning plate 21 on the raw materials in the cavity 45 is enhanced.

In a preferred embodiment, a left stopper 28 is further fixed to a side of the second pin 22 away from the left side turning plate 21. For example, the left stop 28 may be configured as a boss that is fixed to the left hopper 20. The left stop 28 serves to protect the side flaps 21 from impacts.

Similarly, the right hopper 30 is also provided with a right turning plate 31, a right baffle plate 36, a right sealing element 68 and a right limiting element 38. The right-side turning plate 31 is also overlapped on the central turning plate 50 and is hinged with the right hopper 30 through a pin shaft. During the turning of the right hopper 30, the right flap 31 has the same movement as the left flap 21.

Fig. 2 shows a schematic view of a hopper-flipped state of the paver hopper apparatus 100 as shown in fig. 1. As shown in fig. 2, the left bin 20 and the bin 30 are each connected to the central flap 50 by a linkage 70. The link mechanism 70 includes an active lever 80. One end of the active rod 80 is a free end 81, and the other end is a fixed end 82. The fixed end 82 is attached to the hopper 16 for rotation with the hopper 16 inverted. Thus, the first end 81 of the driving rod 80 can rotate under the driving of the hopper overturning.

In addition, the linkage mechanism 70 includes a linkage rod 90. For clarity, the linkage rod 90 associated with the right hopper 30 is illustrated here. As shown, the linkage rod 90 is a right-angle link rod, which is connected to the frame 10 at a right-angle portion 93 through a rotating shaft 95, so that the linkage rod 90 can rotate around the rotating shaft 95. The first end 91 of the linkage rod 90 abuts against the lower end face 52 of the central flap 50, while the second end 92 thereof is connected to the free end 81 of the active rod 80, for example, in an overlapping or hinged manner.

Therefore, when the hopper 16 is turned inward in a direction approaching the bottom surface 15, the free end 81 of the driving rod 80 is driven to rotate in a direction away from the bottom surface 50, and the second end 92 of the linkage rod 90 is driven to rotate in a direction away from the bottom surface 50. When the second end 92 of the linkage rod 90 rotates away from the bottom surface 50, the first end 91 of the linkage rod 90 slides on the lower end surface 52 of the central flap 50 and pushes the central flap 50 to turn upwards around the connecting shaft 55. Similarly, when the hopper 16 is turned outwards away from the bottom surface 15, the central turning plate 50 is driven to turn downwards around the connecting shaft 55. Finally, the linkage of hopper 16 with central flap 50 is achieved by linkage 70.

In a preferred embodiment, a roller 94 is also provided at the first end 91 of the linkage rod 90. In this way, the first end 91 of the linkage rod 90 can roll on the central flap 50 through the roller 94, so that the central flap 50 can be turned over more smoothly and stably.

The working process of the hopper device 100 of the paver according to the present invention will be briefly described below by taking the left hopper 20 as an example.

When the paver hopper apparatus 100 needs to dump the material in the cavity 45 onto the conveyor belt 18, the left hopper 20 needs to be turned inward. During the process of turning over the left hopper 20, the central flap 50 is turned over upward around the connecting shaft 55 under the driving of the link mechanism 70. At the same time, the left side flap 21 hinged to the left hopper 20 is also pivoted about the second pin 22 by the central flap 50. On the other hand, as the left hopper 20 is turned, the left flap 21 is also rotated in the direction of the center flap 50. Therefore, along with the turning of the left hopper 20, the central flap 50 and the left flap 21 gradually rotate from the initial horizontal state to the vertical state, thereby achieving the purpose of preventing the raw materials in the cavity 45 from spilling.

Similarly, when the raw material in the left hopper 20 is completely poured, the left hopper 20 will be turned outwards. At this time, the central flap 50 and the left flap 21 are restored to the horizontal state by the driving of the link mechanism 70.

Although not described in detail, it will be readily appreciated that the movement of the right hopper 30 and its associated components similarly proceeds during the above-described process.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and should not be construed as limiting the present invention in any way. Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing examples, or that equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
