Description

Technical Field

[0001] This utility model belongs to the technical field of road construction equipment, and in particular relates to an asphalt concrete pavement unloading device. Background Technology

[0002] During the construction of asphalt concrete pavement, asphalt concrete needs to be unloaded from transport vehicles onto construction equipment such as pavers. Most existing unloading devices have relatively simple structures and single functions. During the unloading process, the direction and angle of the discharge are difficult to adjust flexibly, failing to meet the needs of different construction scenarios. For example, when there are obstacles on the construction site or when the asphalt concrete needs to be unloaded to a specific location, existing unloading devices are often inadequate, leading to low unloading efficiency and potentially affecting construction quality. Therefore, developing an asphalt concrete pavement unloading device that can flexibly adjust the discharge direction and angle is of significant practical importance. Utility Model Content

[0003] The purpose of this utility model is to provide an asphalt concrete pavement unloading device to solve the problems of existing unloading devices having simple structure, single function, difficulty in flexibly adjusting the direction and angle of material discharge, and inability to meet the needs of different construction scenarios.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an asphalt concrete pavement unloading device includes a hopper, a support assembly, a rotation adjustment assembly, and a discharge plate. The support assembly includes a support plate and multiple legs. The hopper is fixedly installed in the middle of the support plate. Legs are provided at the four corners of the lower end face of the support plate. The hopper is fixed to the operating surface by the support assembly. A discharge port is opened at the lower end of the hopper. The rotation adjustment assembly is installed at the lower end of the support plate.

[0005] Furthermore, the rotation adjustment assembly includes a rotation motor, an internal gear ring, a gear, a connector, a sliding plate, a support plate, a hinge frame, and two electric telescopic rods. The internal gear ring is disposed on the lower end face of the support plate and located outside the hopper. The gear is rotatably disposed on the lower end face of the support plate and meshes with the internal gear ring. The rotation motor is disposed on the upper end face of the support plate, and its output shaft passes vertically through the support plate and is fixedly connected to the gear. The rotation motor drives the gear to rotate. The support plate is disposed at the lower end of the hopper, and a slide rail is provided along the circumferential direction on the outer wall of the support plate. The upper end of the connector is fixedly connected to the lower end face of the internal gear ring, and the lower end of the connector is fixedly connected to one end of the sliding plate. The other end of the sliding plate is slidably connected to the slide rail on the outer wall of the support plate. Two electric telescopic rods are vertically disposed on the lower end face of the sliding plate, and the lower ends of both electric telescopic rods are fixedly connected to the upper end of the hinge frame. The hinge frame is hinged to the feeding plate.

[0006] Furthermore, the upper end of the feeding plate is hinged to the hinge frame, and the lower end of the feeding plate is inclined and located below the feeding port of the hopper.

[0007] Furthermore, the lower end of the feed plate has two parallel long slots along its length, and each long slot is hinged with a limit telescopic rod.

[0008] Furthermore, one end of the limiting telescopic rod is hinged to one end of the long groove. When not in use, the limiting telescopic rod is placed in the long groove. When in use, the other end of the limiting telescopic rod is vertically downward and set on the operating surface.

[0010] 1. This utility model, by setting up a rotation adjustment component, drives the gear to rotate by a rotating motor, which in turn drives the internal gear ring to rotate. The internal gear ring drives the sliding plate to slide on the slide rail of the support plate through the connecting piece, thereby driving the material feeding plate to rotate around the hinge frame, realizing the horizontal rotation adjustment of the material feeding plate, which can flexibly adjust the feeding direction to adapt to different construction scenarios.

[0011] 2. The two electric telescopic rods of this utility model can drive the unloading plate to swing up and down around the hinge frame, thereby adjusting the height of the unloading plate and further improving the flexibility of unloading.

[0012] 3. The lower end face of the feeding plate of this utility model is provided with a limiting telescopic rod.

The motor 4 drives the gear 11 to rotate. The support plate 5 is set at the lower end of the hopper 1. The outer wall of the support plate 5 is provided with a slide rail 15 along the circumference. The upper end of the connector 12 is fixedly connected to the lower end face of the inner gear ring 10. The lower end of the connector 12 is fixedly connected to one end of the sliding plate 13. The other end of the sliding plate 13 is slidably connected to the slide rail 15 on the outer wall of the support plate 5. Two electric telescopic rods 6 are vertically provided on the lower end face of the sliding plate 13. The lower ends of the two electric telescopic rods 6 are fixedly connected to the upper end of the hinge frame 7. The hinge frame 7 is hinged to the feeding plate 8.

[0023] Furthermore, the upper end of the feeding plate 8 is hinged to the hinge frame 7, and the lower end of the feeding plate 8 is inclined and located below the feeding port 16 of the hopper 1.

[0024] Furthermore, two long slots 14 are arranged side by side along the length of the lower end of the lower surface of the feeding plate 8, and a limit telescopic rod 9 is hinged in each long slot 14.

[0025] Furthermore, one end of the limiting telescopic rod 9 is hinged to one end of the long groove 14. When not in use, the limiting telescopic rod 9 is placed in the long groove 14. When in use, the other end of the limiting telescopic rod 9 is vertically downward and set on the operating surface.

[0026] Working principle:

[0027] The working principle of this utility model is as follows: the rotating motor 4 drives the gear 11 to rotate, the gear 11 meshes with the internal gear ring 10, thereby driving the internal gear ring 10 to rotate. The internal gear ring 10 drives the sliding plate 13 to slide on the slide rail 15 of the support plate 5 through the connecting piece 12, thereby driving the two electric telescopic rods 6, the hinge frame 7 and the material plate 8 hinged to the hinge frame 7 to rotate, realizing the horizontal rotation adjustment of the material plate 8; at the same time, the two electric telescopic rods 6 can drive the hinge frame 7 to move up and down, realizing the vertical adjustment of the material plate 8; the material plate 8 is hinged to the hinge frame 7, realizing the angle adjustment of the material plate 8; the limiting telescopic rod 9 on the lower end face of the material plate 8 can extend during use to increase the stability of the material plate 8.

[0028] Work process:

[0029] Preparation:

[0030] Place the unloading device on the operating surface using the support legs 3, ensuring stability. Check that components such as the rotating motor 4, the electric telescopic rod 6, and the limit telescopic rod 9 are functioning properly.

[0031] Horizontal adjustment:

[0032] When the feeding direction needs to be adjusted, the rotary motor 4 is started. The output shaft of the rotary motor 4 drives the gear 11 to rotate, and the gear 11 meshes with the internal gear ring 10, causing the internal gear ring 10 to start rotating. The internal gear ring 10 drives the sliding plate 13 to slide on the slide rail 15 of the support plate 5 through the connecting piece 12. The sliding plate 13 drives the two electric telescopic rods 6, the hinge frame 7, and the feeding plate 8 hinged to the hinge frame 7 to rotate, thereby realizing the horizontal rotation adjustment of the feeding plate 8. By observing whether the feeding direction meets the requirements, the rotary motor 4 is stopped in time.

[0033] Vertical adjustment:

[0034] When the material discharge height needs to be adjusted, activate the two electric telescopic rods 6. These rods will move the hinge frame 7 and the discharge plate 8 on it vertically, allowing for vertical adjustment of the discharge plate 8. Observe whether the discharge height meets the requirements and stop the two electric telescopic rods 6 as needed.

[0035] Angle adjustment:

[0036] If the angle of the feed plate 8 needs to be adjusted, adjust the hinge angle between the upper end of the feed plate 8 and the hinge frame 7 to achieve the adjustment of the feed plate 8 angle. Observe whether the feed angle meets the requirements and stop the adjustment in time.

[0037] Limit fixed:

[0038] Once the feeding direction and angle are determined, extend the limiting telescopic rod 9 on the lower end face of the feeding plate 8, so that its lower end is vertically downward and positioned on the operating surface. The limiting telescopic rod 9 can increase the stability of the feeding plate 8 and prevent the feeding plate 8 from shaking during the feeding process.

[0039] Unloading operation:

[0040] The asphalt concrete is poured into the hopper 1, and then falls through the discharge port 16 of the hopper 1 onto the discharge plate 8. It then slides down the discharge plate 8 to the designated position, completing the unloading operation.

[0041] Reset operation:

[0042] After unloading, first retract the limit telescopic rod 9 back into the long slot 14, then start the electric telescopic rod 6 and the rotating motor 4 to restore the unloading plate 8 to its initial position for the next use.

[0043] The unloading device of this invention can flexibly adjust the unloading direction and angle, improve unloading efficiency, and adapt to different construction scenarios.
