Description

Technical Field

[0001] The utility model relates to the technical field of pavers, in particular to a hopper conveying mechanism for pavers. Background Art

[0002] The paver is a key equipment used to lay asphalt or other pavement materials in road construction. Its core function is to spread the material evenly on the road surface through its feeding mechanism to form a flat and dense pavement structure. However, the existing paver has some technical problems in the feeding process.

[0003] Traditional paver feeding mechanisms usually use hoppers and conveyor belts to deliver materials to the paving area. During this process, material flow interruption may occur. Another method is to use threaded blades with a feeding pipe to deliver materials to the paving area. This method may also cause material flow interruption in the middle of the material. These problems will lead to uneven paving of materials. Material flow interruption will cause partial material shortage during the operation of the paver, thereby reducing the quality and efficiency of road construction.

[0004] For this purpose, we propose a paver hopper conveying mechanism. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment: A hopper conveying mechanism for a paver, such as Figure 1-Figure 4 As shown, it includes a paver 1 and a hopper 2 arranged at the front end of the paver 1.

In this embodiment, the conveying mechanism includes a front part, a middle part and a rear part. The front part conveys the material in the hopper 2 and guides it upward. The middle part is a hollow space. The material guided upward flows in from the top of the middle part and falls into the bottom of the middle part. The rear part conveys away the material accumulated in the middle part but only conveys the material from the bottom of the material, thereby forming a flow interruption space, so that the flow interruption and air part generated in the front transportation can be processed in the middle part, so that the rear part can stably output the material, thereby making the material spread by the paver 1 more uniform and without temperature difference agglomeration.

[0025] Specifically, the front body is the front conveying pipe 3, the rear body is the rear conveying pipe 4, a middle body transfer space 5 is formed between the front conveying pipe 3 and the rear conveying pipe 4, a lifting block 7 is fixedly installed at the rear end of the front conveying pipe 3, the lifting block 7 is a cylinder with an inclined front end face and a flat upper side, the lifting block 7 and the front conveying pipe 3 form a lifting space 8, the material is guided by the inclined surface of the lifting block 7 and flows through the lifting space 8 to the transfer space 5, and a stopper block 10 is fixedly installed on the front end face of the rear conveying pipe 4, the stopper block 10 is a cylindrical block and the bottom end of the stopper block 10 is flat and the transfer The spaces 5 are connected to form a feed space 11, and the blocking block 10 blocks the upper part of the material pile in the transfer space 5, so that the material pile can only enter the rear feed pipe 4 from the bottom of the feed space 11, wherein a stirring shaft 12 is arranged in the transfer space 5, and the bottom end of the stirring shaft 12 extends to the bottom of the transfer space 5 and is fixedly installed with a stirring blade 13, and the stirring shaft 12 is fixedly connected to an external motor. After starting, the stirring shaft 12 rotates to drive the stirring blade 13 to rotate in the material pile, so that the material pile keeps flowing, and at the same time, drives the material to flow to the feed space 11, and is transported to the rear for paving.

[0026] Furthermore, the front part also includes a front conveying mechanism, which can be a conveyor belt type, a spiral blade type or a push rod type. In the present embodiment, it is a spiral blade type, specifically including a main shaft 6 movably installed between the blocking block 10 and the lifting block 7. The main shaft 6 passes through the front conveying pipe 3 and extends into the hopper 2. The main shaft 6 corresponds to the position in the front conveying pipe 3 and is fixedly installed with a front feeding spiral blade 15. The front feeding spiral blade 15 is a spiral blade structure, and the material is transported in the front conveying pipe 3 through the front feeding spiral blade 15.

[0027] Furthermore, the front feed pipe 3 extends to the top opening of the hopper 2, and the material enters the front feed pipe 3 from the opening. The main shaft 6 has multiple groups of feed blades 14 evenly and fixedly installed on the part corresponding to the hopper 2. The feed blades 14 have a pushing inclination angle to push the material into the front feed pipe 3.

[0028] Furthermore, a material guide platform 9 is fixedly installed on the rear end face of the lifting block 7.
