Technical Field

The utility model relates to a paver hopper device and a paver comprising the paver hopper device.

Background

In the construction process of the conventional paver, when the skip is discharged and leaves, the paver needs to close the hopper to pour the materials in the hopper onto the scraper conveyer. In the process, when the hopper of the paver, which is not provided with the hopper turning plate, is closed, more materials are scattered on the road surface in front of the hopper, so that the road surface needs to be cleaned in time, the labor intensity of constructors is increased, and the construction efficiency is reduced. The paver hopper with the hopper turning plate can collect and dump most materials on the scraper conveyer, so that the construction efficiency can be improved.

However, in long-time paving operations, a paver with a hopper-mounted material-turning plate will have a small amount of material particles splattered below the material-turning plate during turning and feeding. These material particles can pad in the stirring board below after long-time accumulation to will turn over the stirring board bed hedgehopping, thereby lead to influencing the upset of stirring board and appear the jamming, disturb the normal unloading of skip, can cause the stirring board to receive striking or scrape the pressure damage when serious, seriously influence paver's operating efficiency.

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 11, the frame 10 having a floor 15. Hoppers 16 are also provided at both ends of the frame 10, respectively. The hopper 16 can be turned over under the drive of the paver 11, so that the hopper closing action is completed.

As shown in fig. 1, a flap 20 is also provided on the base plate 15. The flap 20 is hinged to the base plate 15 by means of a connecting shaft 25. The connecting shaft 25 is arranged in a lateral direction and is arranged on the inner side of the flap 20 close to the bottom plate 15, so that the flap 20 can rotate relative to the bottom plate 15.

Meanwhile, a link mechanism 22 is also provided between the hopper 16 and the flap 20. The hopper 16 and the turning plate 20 are connected through a connecting rod mechanism 22. Under the action of the link mechanism 22, the hopper 16 can drive the turning plate 20 to rotate relative to the bottom plate 15.

Specifically, when the hopper is not turned, the flap 20 is in the same plane as the bottom plate 15. Along with the overturning of the hopper 16, the turning plate 20 can rotate around the connecting shaft 25 in 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 turning plate 20 plays a role in blocking the raw material of the hopper 16 from being sprayed out.

In an actual paving operation, the operator finds that the turning plate 20 can block the raw material of the hopper 16 from being spilled during the process of turning the hopper, but when the skip (not shown) pours the paving auxiliary material into the hopper 16 or the vibration of the hopper 16 is large, a small amount of auxiliary material still splashes from the end 21 of the turning plate 20 to the lower part of the turning plate 20. As these adjuvants accumulate for a long period of time, the flap 20 will be raised and the flap 20 will be affected to return to a horizontal state, thereby severely affecting the normal turning of the flap 20.

Thus, as shown in fig. 1, a recess 30 is also provided in the frame 10 at the lower end of the flap 20, the recess 30 having a first cavity 32 configured to receive gravel. The number of grooves 30 is preferably two, and the two grooves 30 are respectively arranged at the end portions 21 at the two ends of the flap 20.

Thus, during the spreading operation, when a small amount of auxiliary material splashes down from the end 21 of the flap 20 to the lower side of the flap 20, the auxiliary material can first enter the first inner cavity 32 in the groove 30, so as to prevent the auxiliary material gravel from accumulating under the flap 20 and affecting the normal turning of the flap 20.

As shown in fig. 1, in a preferred embodiment, the bottom surface 25 of the recess 30 is provided as a slope and is arranged in a vertical direction. Meanwhile, the bottom surface 25 of the recess 30 is provided to extend in a direction away from the bottom plate 15, i.e., the lower end of the recess 30 is provided at a side of the upper end thereof away from the bottom plate 15. So that when the auxiliary material is accumulated more in the cavity 32, it can slide downward by its own weight to reach the lower end of the recess 30 and then drop on the ground.

In a preferred embodiment, the bottom 25 of the recess 30 is disposed at an angle of 30 ° -45 ° to the vertical. Multiple experiments on site show that by setting the inclination of the bottom surface 25 in this range, the auxiliary material gravel has a proper falling speed, so that the auxiliary material gravel can be prevented from falling too slowly to cause blockage in the groove 30, and the problem of splashing of the auxiliary material gravel caused by too fast falling can be avoided.

As shown in fig. 1, a carrier box 40 is further disposed at the lower end of the groove 30, and the carrier box 40 may be configured as a cylinder, for example. A second interior cavity 42 is defined within the carrier box 40 in communication with the first interior cavity 32. Therefore, when the auxiliary material reaches the lower end of the groove 30, the auxiliary material can enter the material carrying box 40, so that on one hand, the recycling of the auxiliary material during splashing is facilitated, and on the other hand, the auxiliary material can be prevented from polluting the paved road surface.

Further, the carrier box 40 is detachably connected to the frame 10. The connection mode can be pin connection, for example, so that the auxiliary materials in the carrier box 40 can be cleaned and collected by operators more conveniently.

As shown in fig. 1, in the present utility model, the upper end of the recess 30 is disposed flush with the fixed end 25 of the flap 20 near the bottom plate 15 and is connected to the fixed end 25. It will be readily appreciated that since the bottom surface 25 of the recess 30 is arranged to extend away from the base plate 15, when the fixed end 25 of the flap 20 adjacent to the base plate 15 is flush with the upper end of the recess 30, the entire recess 30 will be located outside the fixed end 25 away from the base plate 15. Thus, when flap 20 is flipped to a horizontal position, it will interface with the adjuvant within cavity 32, thereby exerting a downward pressure on the adjuvant. By means of said pressure, the entry of the auxiliary material in said recess 30 into the carrier box 40 can be facilitated even more.

Fig. 2 is a schematic view of the recess 30 of the paver hopper apparatus 100 shown in fig. 1. In a preferred embodiment, as shown in fig. 2, the upper end of the recess 30 is provided with an opening 50, and a sidewall 55 of the opening 50 is configured as a tapered surface such that an upper end 51 of the opening 50 is larger in size than a lower end 52. By this arrangement, the opening 50 can be configured in a substantially bell-mouth shape, thereby further facilitating the collection of falling auxiliary material by the recess.

In a preferred embodiment, the angle of inclination of the conical surface is set to 30 ° -60 °. Experiments in the field have shown that by setting the angle of the opening 50 in this angular range a better collection of the recess 30 is obtained.

The operation of the hopper device 100 for a paver according to the present utility model is briefly described below.

During the spreading operation, when the micro-ingredients in the hopper 16 splash from the end 21 of the flap 20 to the lower side of the flap 20, they first enter the first cavity 32 in the recess 30 and then fall into the carrier box 40 under the action of gravity. Therefore, the auxiliary materials which are splashed down can be prevented from affecting the normal overturning of the overturning plate 20, and the working efficiency is improved. And the splashed auxiliary materials can be collected, so that the operation cost is reduced.

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.
