Description

Hopper device of paver

Technical Field

The utility model relates to a hopper device of a paver.

Background

The main function of the hopper device of the paver is to receive the pavement paving raw materials dumped from the material conveying vehicle at the front side of the paver, so as to provide raw materials for the paving and ironing device at the rear side of the paver, and meanwhile, the material conveying device can also play a role in balancing the gravity center. The existing hopper device is hinged on the frame through a pin shaft, an oil cylinder is connected with an oil cylinder mounting plate on the hopper, and the opening and closing actions of the hopper at a certain angle can be completed through the driving of the oil cylinder, so that the function of gathering paving raw materials towards the center of the bin is realized.

In the process of opening and closing the hopper device, raw materials in the hopper are easy to overflow or spill out of the hopper. Therefore, a baffle structure is usually fixed at the front end of the hopper, and the baffle is connected with the hopper through a transmission mechanism, so that the baffle can be matched with the opening and closing action of the hopper to make a matched action. Therefore, the overflow and the sprinkling of the raw materials can be effectively reduced.

However, during operation, the transmission mechanism may be jammed due to the influence of sundries such as gravel, and the normal rotation of the baffle plate is affected. When the transmission mechanism is blocked, operators often need to stop temporarily for repair, and the working efficiency is seriously affected.

Detailed Description

The utility model is described below with reference to the accompanying drawings.

Fig. 1 shows a paver hopper apparatus 100 in accordance with one embodiment of the utility model. As shown in fig. 1, the paver hopper apparatus 100 includes a frame 10 for attachment to a paver, the frame 10 having a floor 15. A hopper 16 is further provided on the frame 10, and the hopper 16 includes a left hopper 20 and a right hopper 30 symmetrically provided at both sides of the frame 10. The left hopper 20 and the right hopper 30 have a horizontal plane parallel to the bottom plate 15 and a vertical plane perpendicular to the bottom plate 15, respectively. By this arrangement, the left hopper 20 and the right hopper 30 together with the frame 10 form a hollow housing 40 having a cavity 45, said cavity 45 being adapted to receive the raw materials required for paving. A conveyor belt 18 is arranged on the base plate 15, which conveyor belt 18 is used for conveying the raw material required for paving to the ironing device of the paver.

Meanwhile, the left hopper 20 and the right hopper 30 are hinged to the frame 10 through a first pin 19 arranged on the bottom plate 15. The first pins 19 are arranged longitudinally and are provided on the inner sides of the left hopper 20 and the right hopper 30 towards the bottom plate 15, so that the hoppers 16 can be turned inwards at an angle around said first pins 19. In this way, the material within the hopper 16 may be poured onto the conveyor 18 faster under the force of gravity as the hopper 16 is inverted.

In order to prevent the material in the cavity 45 from spilling out of the housing 40 when the hopper 16 is turned inwards, a central flap 50 is also provided on the bottom plate 15. The central flap 50 is hinged to the base plate 15 by means of a connecting shaft 55. The connecting shaft 55 is arranged in a lateral direction and is arranged on the inner side of the central flap 50 close to the bottom plate 15, so that the central flap 50 can rotate relative to the bottom plate 15. When the hopper is not turned, the central flap 50 is in the same plane as the bottom plate 15. With the overturning of the hopper 16, the central turning plate 50 can rotate around the connecting shaft 55 towards a direction approaching to the bottom plate 15 under the driving of the hopper 16, and then gradually changes from a horizontal state to a vertical state, so that the central turning plate 50 plays a role in blocking the raw material from being spilled. Also, the center flap 50 is preferably a rectangular flap to ensure that it has the maximum blocking area. The movement of the hopper 16 with the central flap 50 will be described in detail below.

Fig. 2 shows a schematic view of a hopper turned state of the paver hopper apparatus 100 shown in fig. 1. As shown in fig. 2, the left hopper 20 and the hopper 30 are each connected to the center flap 50 by a linkage 70. The linkage 70 includes an active lever 80. One end of the driving rod 80 is a free end 81, and the other end is a fixed end 82. The fixed end 82 is connected to the hopper 16 and is rotatable as the hopper 16 is turned over. Thus, the first end 81 of the driving rod 80 can rotate under the driving of the hopper turning.

In addition to this, the linkage 70 includes a linkage rod 90. For clarity, the description is provided herein with respect to the link 90 associated with the right hopper 30. As shown in fig. 2, the first end 91 of the linkage rod 90 abuts against the lower end surface 52 of the central flap 50, and the second end 92 is connected to the free end 81 of the driving rod 80.

In the present utility model, the link 90 is provided as a right angle link such that the second end 92 of the link 90 is formed as a bent portion 93. The bending part 93 is connected to the frame 10 through a rotating shaft 95, so that the linkage rod 90 can rotate around the rotating shaft 95.

As shown in fig. 2, the free end 81 of the driving rod 80 is disposed to abut against the bending portion, and when the hopper 16 turns inwards in a direction approaching to the bottom plate 15, the free end 81 is driven to rotate in a direction away from the bottom plate 50, so as to drive the second end 92 of the linkage rod 90 to rotate in a direction away from the bottom plate 50. When the second end 92 of the link lever 90 rotates away from the bottom plate 50, the first end 91 of the link lever 90 slides on the lower end surface 52 of the center flap 50 and pushes the center flap 50 to turn upward about the connection shaft 55.

Similarly, when the hopper 16 is turned outwardly away from the base plate 15, the second end 92 of the linkage rod 90 is rotated away from the base plate 50. The central flap 50 will now flip downwards about the connecting shaft 55 under the force of gravity. Finally, the linkage of the hopper 16 to the central flap 50 is achieved by means of a 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 link lever 90 can roll on the center flap 50 by the roller 94, so that the center flap 50 can be turned over more smoothly.

Fig. 3 is an enlarged view of a portion of the paver hopper apparatus 100 shown in fig. 1. As shown in fig. 3, a connecting piece 96 is further disposed between the driving rod 80 and the linkage rod 90, and the connecting piece 96 can realize rigid connection between the driving rod 80 and the linkage rod 90 when the linkage rod 90 is jammed.

When a rigid connection is made between the drive rod 80 and the linkage rod 90, the overturning force of the hopper 16 can be directly transmitted to the linkage rod 90 through the drive rod 80. Under the action of the overturning force, the hopper 16 can drive the linkage rod 90 to rotate, so that the linkage rod 90 falls down to return, and normal function is ensured.

As shown in fig. 3, the connecting member 96 is preferably configured as a chain 97 having a first end 971 fixedly coupled to the free end 81 of the driving rod 80 by a first pin 981 and a second end 972 fixedly coupled to the bent portion 93 by a second pin (not shown).

As shown in fig. 3, when the linkage rod 90 can rotate synchronously with the driving rod 80 during the process of turning the hopper 16 in a direction approaching to the bottom plate 15, the relative distance between the first pin shaft 981 and the second pin shaft will not change, and the chain 97 is in a flexible state at this time, so that the transmission connection between the driving rod 80 and the linkage rod 90 will not be affected.

When the interlocking bar 90 is jammed due to the gravel, the relative distance between the first pin 981 and the second pin is gradually increased as the driving bar 80 continues to rotate, thereby stretching the chain 97 until the chain 97 is in a tight state. At this time, as the driving rod 80 continues to rotate, the rotational force of the driving rod 80 directly acts on the linkage rod 90 through the tight chain 97, so that the driving rod 80 and the linkage rod 90 are rigidly connected. Then, the driving rod 80 pulls the linkage rod 90 to drop and return, so that the normal function of the linkage rod 90 is ensured, and the shutdown repair is avoided.

When the paving operation is completed, the operator can clean the linkage rod 90, so that the driving rod 80 and the linkage rod 90 are restored to the transmission connection state.

In a preferred embodiment, a convex arc surface 811 is provided at the free end 81 of the driving lever 80, and a concave arc surface 931 is provided at the bent portion 93 of the link lever 90 to fit the convex arc surface 811. It will be readily appreciated that the risk of jamming of the drive rod 80 and the linkage rod 90 can be reduced by the arcuate mating connection between the convex arcuate surface 811 and the concave arcuate surface 931.

In a preferred embodiment, as shown in fig. 1, side flaps are also provided on both the left and right hoppers 20, 30. The left side flap 21 at the position where the left hopper 20 is provided is described hereinafter as an example.

On the one hand, the left flap 21 is hinged to the left hopper 20 by means of a second pin 22. The second pin 22 is arranged at the position where the left turning plate 21 and the left hopper 20 are intersected, and the intersecting edges of the second pin and the left turning plate 21 are arranged in the same direction. Meanwhile, the left side flap 21 is located above the center flap 50 in the vertical direction, so that the left side flap 21 is overlapped on the center flap 50. Thus, when the center flap 50 rotates about the connection shaft 55 in a direction approaching the bottom plate 15, the center flap 50 lifts the left flap 21 to rotate about the second pin 22. On the other hand, the left side turning plate 21 is turned in a direction approaching the center turning plate 50 by the driving of the hopper 16. During this process, the left flap 21 likewise changes gradually from a horizontal state to a vertical state, so that the left flap 21 likewise acts as a barrier to the spillage of the material in the cavity 45.

As shown in fig. 1, a left seal 60 is also provided at the end of the left 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 side turning plate 21 rotates around the second pin shaft 22 at the same time, the left side turning plate 21 is always abutted against the contact surface 65, so that no gap exists between the left hopper 20 and the left side turning plate 21, and raw materials in the cavity 45 are prevented from being spilled out through the gap. Thus, the left seal 50 can function as a seal.

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

In a preferred embodiment, a left stop 28 is also fixed to the side of the second pin 22 facing away from the left flap 21. For example, the left stop 28 may be configured as a boss secured to the left hopper 20. The left stop 28 serves to protect the side flap 21 from impacts.

Similarly, the right hopper 30 is provided with a right rollover plate 31, a right striker plate 36, a right seal 68, and a right stopper 38. The right side turning plate 31 is also lapped on the center turning plate 50 and is hinged with the right hopper 30 through a pin shaft. During the overturning process of the right hopper 30, the right rollover plate 31 and the left rollover plate 21 have the same movement process.

The operation of the hopper device 100 for a paver according to the present utility model will be briefly described below by taking the left hopper 20 as an example.

When the paver hopper apparatus 100 needs to pour the material within the cavity 45 into the conveyor 18, the left hopper 20 needs to be turned inwardly. During the overturning process of the left hopper 20, the central turning plate 50 can be overturned upwards around the connecting shaft 55 under the driving of the link mechanism 70. At the same time, the left flap 21 hinged to the left hopper 20 will also rotate about the second pin 22 under the lifting of the central flap 50. On the other hand, as the left hopper 20 is turned over, the left side flap 21 is also turned in the direction of the center flap 50. Thus, as the left hopper 20 is turned over, the center turning plate 50 and the left turning plate 21 gradually rotate from the initial horizontal state to the vertical state, thereby achieving the purpose of preventing the raw material in the cavity 45 from being spilled.

Similarly, when the raw materials in the left hopper 20 are poured, the left hopper 20 is turned outwards. At this time, the center turning plate 50 and the left side turning plate 21 are restored to the horizontal state by the driving of the link mechanism 70.

Although not described in detail, it is readily understood that the movement of the right hopper 30 and its associated components in the above process is similarly performed.

When the interlocking bar 90 is jammed due to the gravel, the relative distance between the first pin 981 and the second pin is gradually increased as the driving bar 80 continues to rotate, thereby stretching the chain 97 until the chain 97 is in a tight state. At this time, as the driving rod 80 continues to rotate, the rotational force of the driving rod 80 directly acts on the linkage rod 90 through the tight chain 97, so that the driving rod 80 and the linkage rod 90 are rigidly connected. Then, the driving rod 80 pulls the linkage rod 90 to drop and return to ensure the normal function of the linkage rod 90

Finally, it should be noted that the above description is only of a preferred embodiment of the utility model and is not to be construed as limiting the utility model in any way. Although the utility model 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 techniques described in the foregoing examples, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
