Description

Technical Field

[0001] The utility model relates to the technical field of asphalt regeneration auxiliary equipment, in particular to a wear-resistant discharge nozzle device. Background Art

[0002] The asphalt regeneration equipment transports the materials on the conveyor belt to the feeding end of the regeneration drying drum through the elevator. The feeding port of the elevator and the discharging port of the conveyor belt are connected through the discharging nozzle device.

[0003] In the prior art, the discharge nozzle device is made of steel plates with good wear resistance. However, since the discharge nozzle device needs to transport materials such as aggregates and asphalt recycled materials, during long-term use, the collision of materials with the steel plates will still cause wear of the steel plates, resulting in damage to the discharge nozzle device. The disassembly and replacement procedures of the discharge nozzle device are relatively complicated and require a long production time, thereby affecting production efficiency. Utility Model Content

[0004] In view of the shortcomings in the above-mentioned existing production technology, the applicant provides a wear-resistant discharge nozzle device. By setting up an interlayer mechanism and a first lining plate, it is possible to prevent the material from directly contacting the wall surface of the discharge nozzle device, thereby preventing the material from colliding with the discharge nozzle device, ensuring the structural integrity of the discharge nozzle device, and extending the service life of the discharge nozzle device.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A wear-resistant discharge nozzle device comprises a first hopper for feeding materials and a second hopper for discharging materials, wherein the second hopper is fixed to the bottom of the first hopper, and the inner space of the second hopper is connected to the inner space of the first hopper;

[0007] The first hopper is provided with a first discharging slope, the second hopper is provided with a second discharging slope, and the second discharging slope is connected to the first discharging slope;

[0008] The first discharging slope and the end surface of the second discharging slope are both equipped with a first lining plate through a partition mechanism, and the material is moved from the feeding end to the discharging end through the first lining plate.

[0009] As a further improvement of the above technical solution:

[0010] The partition mechanism comprises a plurality of angle irons arranged at even intervals.

[0011] The structure of a single angle iron is as follows: it comprises two vertically arranged partition parts, and the connection part of the two partition parts forms a connection part.

[0012] For a single angle iron, the inner side of the connecting portion is provided with a rounded corner.

[0013] The single angle iron is fixed to the end surfaces of the first discharge inclined surface and the second discharge inclined surface through corresponding connecting parts.

[0014] The structure of the first hopper is as follows: it includes a first shell, an upper flange is fixed above the outer wall of the first shell, a first connecting flange is fixed below the outer wall of the first shell, and one side end face of the first shell is arranged inclined to form a first discharge slope.

[0015] A second lining plate is fixed to the inner wall surface of the first shell.

[0016] The structure of the second hopper is as follows: it includes a second shell, a second connecting flange is arranged above the outer wall of the second shell, and one side end surface of the second shell is arranged tilted to form a second discharge slope.

[0017] The third lining plates are symmetrically arranged on the inner wall surface of the second shell.

[0018] The first hopper and the second hopper are both fixed with lifting ears.

[0019] The beneficial effects of the utility model are as follows:

[0020] The utility model has a compact and reasonable structure and is easy to operate. By arranging the first lining plate, it can avoid direct contact between the material and the wall surface of the discharge nozzle device, thereby preventing the material from hitting the discharge nozzle device, ensuring the structural integrity of the discharge nozzle device, and extending the service life of the discharge nozzle device; at the same time, by arranging the partition mechanism, when the first lining plate is damaged, the material is stuck in the angle iron, so that there is material stored in the hopper to form a buffer layer, thereby preventing subsequent materials from impacting the wall surface of the discharge nozzle device.

[0021] In the utility model, by arranging angle irons, it can be used to support the first lining plate and separate the first lining plate 5 from the first shell and the second shell; at the same time, it can also be used to reduce the flow rate of the material inside the discharge nozzle device after the first lining plate is damaged, and make the material stuck inside the partition mechanism, so that a buffer layer is formed inside the discharge nozzle device to protect the wall surface of the hopper.

[0022] In the utility model, a second lining plate and a third lining plate are arranged, wherein the second lining plate is used to protect the inner wall surface of the first shell, and the third lining plate is used to protect the inner wall surface of the second shell, thereby further reducing the impact of the material on the hopper wall surface and protecting the discharge nozzle device.
