Description

Technical Field

[0001] This application relates to the technical field of the construction of cement stabilized macadam layers on expressways, and particularly relates to a cement stabilized macadam feeding device. Background Technique

[0002] As an important building material, cement stabilized macadam needs to be continuously supplied through a feeding device during production and use. However, during the feeding process of traditional feeding devices, cement stabilized macadam often impacts the wall surface of the feeding tank, resulting in material accumulation in the tank, which affects the continuity and uniformity of feeding. Currently, common solutions are to regularly clean the accumulated materials in the feeding tank or to assist feeding by adding vibration devices. However, these methods not only have low efficiency, but also increase the equipment maintenance cost and operation complexity. Regular cleaning will lead to a decrease in production efficiency and an increase in labor costs; while the vibration device may increase the failure rate and energy consumption of the equipment. Content of the Utility Model

[0003] A cement stabilized macadam feeding device proposed in this application is used to solve the problems raised in the above background technique.

[0004] To achieve the above object, this application adopts the following technical solutions:

[0005] A cement stabilized macadam feeding device includes a feeding tank. An inlet is provided at the top of the feeding tank, and an outlet is provided at the bottom of the feeding tank. An anti-accumulation mechanism is fixedly provided on the inner wall of the feeding tank. The anti-accumulation mechanism includes a plurality of diversion plates arranged circumferentially. The diversion plates are arc-shaped and their concave surfaces face the outlet. One side of the feeding tank is fixedly connected to a side plate. The top of the side plate is fixedly connected to a bracket. A stirring mechanism is fixedly installed at the top of the bracket. The bottom of the side plate is fixedly connected to a mounting plate. An auxiliary discharging mechanism is fixedly installed on one side of the mounting plate close to the outlet.

[0006] By adopting the above technical solutions, a plurality of circumferentially arranged diversion plates with concave surfaces form a basin-like structure to guide the cement stabilized macadam that impacts the inner wall surface of the feeding tank to flow towards the outlet, preventing material accumulation in the feeding tank. The stirring mechanism can disturb the inlet of the feeding tank and the crushed stone material inside it, enabling the crushed stone stabilized material to be fed smoothly. The auxiliary discharging mechanism can further promote the flow of the accumulated material by fine-tuning the angle of the vibration plate, ensuring smooth feeding.

[0007] As a preferred embodiment, the stirring mechanism includes a first motor. The output shaft of the first motor is fixedly connected to a stirring shaft, and a spiral blade is fixedly installed at the lower end of the stirring shaft.

[0008] By adopting the above technical solution, the first motor is responsible for driving the stirring shaft to rotate, and the stirring shaft then drives the spiral blades to disturb the crushed stone material, enabling the crushed stone stabilized material to be discharged smoothly.

[0009] As a preferred embodiment, the auxiliary discharging mechanism includes a second motor. A rotating disk is fixedly installed on the output shaft of the second motor. A first hinge seat is movably connected to one side of the rotating disk close to the discharging port. A connecting rod is hinged inside the first hinge seat. Fixed plates are provided on both the front and rear sides of the discharging port. A vibrating plate is rotatably connected between the two fixed plates. The vibrating plate is in a Z-shaped structure. A second hinge seat is movably connected to one side of the bottom of the vibrating plate. The second hinge seat is hinged to the end of the connecting rod.

[0010] By adopting the above technical solution, the second motor drives the rotating disk to rotate. The rotating disk then drives the connecting rod to reciprocate through the first hinge seat. The connecting rod drives the vibrating plate to swing reciprocally by being movably connected to the second hinge seat. By finely adjusting the angle of the vibrating plate, the flow of the accumulated material can be further promoted to ensure smooth discharging.

[0011] As a preferred embodiment, the bracket is in an L-shaped structure, and symmetrically distributed reinforcing bars are fixedly connected between the two ends of the bracket.

[0012] By adopting the above technical solution, the reinforcing bars can be used to strengthen the strength of the bracket.

[0013] As a preferred embodiment, a wear-resistant coating is fixedly provided on the concave surface of the deflector. The wear-resistant coating is made of one or more of ceramic materials or metal materials.

[0014] By adopting the above technical solution, the wear-resistant coating has stable wear resistance, which can improve the service life and wear resistance of the deflector.

[0015] As a preferred embodiment, a flow control valve is fixedly installed inside the discharging port.

[0016] By adopting the above technical solution, by adjusting the opening degree of the valve of the flow control valve, the discharging speed and flow rate can be controlled to further ensure the uniformity of discharging.

[0017] The beneficial effects of this application:
