Description

Technical Field

[0001] This utility model relates to the field of personal asphalt concrete technology, specifically a recycling chute for asphalt production. Background Technology

[0002] Asphalt concrete recycling equipment utilizes recycling technology to process old asphalt mixtures scraped from failed asphalt pavements. After screening, heating, storage, and metering, the mixtures are added to the mixers of various types of asphalt mixing plants in different proportions, where they are uniformly mixed with the virgin material to produce high-quality asphalt concrete. The main components of asphalt concrete recycling equipment include a hoist, drying drum, hot aggregate silo, and metering hopper.

[0003] However, since the recycled asphalt comes out of the metering hopper and enters the mixing tank of the asphalt mixing plant through a chute, the temperature and slope of the recycled asphalt decrease and the viscosity increases during the flow of the recycled asphalt in the chute, which may cause blockage of the chute and affect the normal operation of production.

[0018] The utility model embodiment provides a regenerative chute for asphalt production, such as Figures 1-2As shown, it comprises a first cylinder 11, an oil inlet 13, an oil outlet 14, a fixed platform 15, a knocking mechanism and a striking pad 20. The lower end of the first cylinder 11 is fixedly provided with a second cylinder 12. The first cylinder 11 and the second cylinder 12 are arranged between a measuring hopper and a stirring cylinder. The inner sides of the first cylinder 11 and the second cylinder 12 are both provided with a material passing groove. The oil inlet 13 is arranged at the feeding position of the first cylinder 11 and the second cylinder 12. The oil outlet 14 is arranged at the discharging position of the first cylinder 11 and the second cylinder 12. The oil inlet 13 and the oil outlet 14 jointly form an oil guiding pipeline system. The fixed platform 15 is fixedly arranged outside the second cylinder 12. The fixed platform 15 comprises a connecting part and a parallel part. The connecting part of the fixed platform 15 is fixedly arranged on the second cylinder 12. The parallel part of the fixed platform 15 is parallel to the outer surface of the second cylinder 12. The striking pad 20 is fixedly arranged on the outer surface of the second cylinder 12 and opposite to the parallel part of the fixed platform 15. The knocking mechanism is arranged between the striking pad 20 and the parallel part of the fixed platform 15.

[0019] The angle between the first cylinder 11 and the second cylinder 12 is less than 180°, thereby eliminating the direct impact of the asphalt regenerant at the connecting position of the two cylinders on the inner wall of the cylinder and prolonging the service life of the chute.

[0020] As shown, Figure 2 The knocking mechanism comprises a power assembly, a sliding sleeve 18, a fixed sleeve 21 and an elastic member. The power assembly is arranged on the horizontal part of the fixed platform 15. The fixed sleeve 21 is fixedly arranged on the striking pad 20. The sliding sleeve 18 is symmetrically arranged with the fixed sleeve 21. The end of the sliding sleeve 18 in contact with the fixed sleeve 21 is provided with symmetrically arranged teeth. The power assembly is used to drive the rotation of the sliding sleeve 18. The elastic member is arranged between the sliding sleeve 18 and the parallel part of the fixed platform 15.

[0021] The power assembly comprises a driving motor 16 and a driving shaft 17. The driving motor 16 is fixedly arranged on the horizontal part of the fixed platform 15. The driving shaft 17 is power-connected to the driving motor 16. The sliding sleeve 18 is sleeved on the outer circular surface of the driving shaft 17. The sliding sleeve 18 is key-connected with the driving shaft 17. The elastic member is a telescopic spring 22.

[0022] The linear speed of the teeth of the sliding sleeve 18 is greater than the axial speed of the telescopic spring 22 when the telescopic spring 22 makes the sliding sleeve 18 rebound.

[0023] When the driving motor 16 drives the driving shaft 17 to rotate, the driving shaft 17 drives the sliding sleeve 18 to rotate through the spline, the teeth of the fixed sleeve 21 abut against the teeth of the sliding sleeve 18, and then the sliding sleeve 18 moves away from the fixed sleeve 21 and compresses the extension spring 22, when the driving shaft 17 drives the sliding sleeve 18 to pass the tooth tip of the fixed sleeve 21, the sliding sleeve 18 continues to compress the extension spring 22 through inertia, when the elastic potential energy of the extension spring 22 is greater than the kinetic energy balance of the sliding sleeve 18, at this time the extension spring 22 releases the elastic potential energy to make the sliding sleeve 18 accelerate to move to the side of the fixed sleeve 21, and then the fixed sleeve 21 hits the impact pad 20, so that the surface of the second cylinder body 12 is periodically knocked.

[0024] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of the present application is defined by the appended claims and their equivalents.
