Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a steel slag ultra-thin high anti-skid road construction spreading device. Background Technology

[0002] Road engineering refers to the entire process of planning, designing, constructing, maintaining and managing roads, as well as the engineering entities involved. Like any other type of civil engineering, road engineering has distinct technical, economic and management characteristics. Road engineering includes pavement construction, which requires spreading gravel on the pavement. Therefore, in the technical field of road engineering, a gravel spreading device for pavement construction is needed.

[0003] A search revealed that patent CN219364235U discloses a road construction gravel spreading device.

[0004] However, the above technical solution has the following problems: the steel slag has a high moisture content, which can easily cause local accumulation. This may block the material feeding point of the device during use, thus affecting the uniformity of the spreading operation. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency for localized accumulation, which may cause blockages at the material feeding point and affect the uniformity of the spreading operation. Therefore, this invention proposes a steel slag ultra-thin high anti-skid pavement spreading device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A steel slag ultra-thin high anti-skid pavement construction spreading device includes a placement box. The bottom of the placement box is provided with a material discharge hole for easy material discharge. A material discharge frame for material discharge is provided on the material discharge hole. Four upright plates are fixedly connected to the four corners of the bottom of the placement box. The bottom of the placement box is provided with a hammering mechanism for easy material discharge to the pavement. The bottom of the placement box is provided with a disassembly and assembly mechanism for easy disassembly and assembly of the material discharge frame.

[0008] In one possible design, the striking mechanism includes two motors, two rotating rods, multiple sleeve blocks, multiple protrusions, two connecting plates, multiple circular plates, multiple striking ends, multiple striking columns, and multiple springs. The two rotating rods are rotatably connected to one side of each of the four upright plates via bearings. One side of each of the two motors is fixedly mounted on the two upright plates via bolts, and the motor's output shaft rotates through the upright plate and is fixedly connected to one end of each rotating rod. Multiple sleeve blocks are fixedly mounted on the two rotating rods. Multiple protrusions are fixedly connected to multiple sleeve blocks. Both connecting plates are fixedly connected to the bottom of the same placement box and are located on opposite sides of the same unloading frame. Multiple striking columns are slidably mounted on the two connecting plates. Multiple striking ends are fixedly mounted on one end of each striking column. Multiple circular plates are fixedly connected to the other end of each striking column. Multiple springs are sleeved on multiple striking columns, and the two ends of each spring are fixedly connected to the sides of the multiple circular plates and connecting plates adjacent to each other via connecting seats.

[0009] In one possible design, the disassembly and assembly mechanism includes two side plates, a rectangular plate, four sliders, two insert plates, two fixing posts, and two push plates. The rectangular plate has rectangular holes through which it is fixedly fitted onto the unloading frame. Both sides of the placement box have grooves adapted to the sliders. The four sliders are slidably connected to the four grooves. One side of each slider is fixedly connected to one side of the two side plates. The two side plates are both L-shaped. The inner walls of the two side plates are tightly fitted to the sides of the two rectangular plates. Fixing posts are threaded onto both side plates. One end of each fixing post is threaded through the two side plates and tightly fitted to the outer side of the placement box. Push plates are fixedly connected to both side plates for easy pushing. Insert plates for stabilizing the unloading frame are fixedly connected to the top two sides of the rectangular plate. Two slots adapted to the insert plates are respectively opened on the bottom two sides of the placement box.

[0010] In one possible design, anti-slip rubber pads are fixedly installed at the points where the two side plates meet the sides of the rectangular plate.

[0011] In one possible design, the material of the plurality of protrusions and the plurality of circular plates is set to wear-resistant high manganese steel.

[0012] In one possible design, the multiple springs are fixed by connecting seats and bolts, and the multiple circular plates are connected to one end of the multiple striking posts by bolts.

[0013] In one possible design, a mounting plate is fixedly connected to one side of the placement box to facilitate connection between the placement box and external mobile equipment.

[0014] In this application, during use, the entire spreading device is reliably connected to an external mobile device (such as a construction vehicle) via bolt holes on the mounting plate. When the mobile device starts and moves, it moves the spreading device along with it, enabling the device to reach the designated construction area. The steel slag and other materials to be spread are placed into the placement box. The material is prepared for discharge through the discharge hole at the bottom of the placement box and the discharge frame installed on the discharge hole. The motor drives the internal spiral blades to rotate, conveying the crushed stone through the spiral blades, preventing the crushed stone from being squeezed and blocked in the inner cavity of the placement box. The crushed stone falls into the discharge frame through the spiral blades and is evenly spread on the ground. Simultaneously, the motor is started. The motor's output shaft drives the rotating rod to rotate. As the rotating rod rotates, the protrusion rotates accordingly. When the protrusion rotates to contact the circular plate, it pushes the circular plate and the striking post to move away from the connecting plate. At this time, the spring sleeved on the striking post is compressed. When the protrusion separates from the circular plate, the spring force causes the striking post and the striking end to move closer to the feeding frame. The striking end strikes the feeding frame. As the motor continues to run, the rotating rod rotates continuously, and the protrusion periodically contacts and separates from the circular plate, causing the striking end to continuously strike the feeding frame, thereby promoting the material to be discharged from the feeding frame, reducing adhesion to the inner wall of the feeding frame, and ensuring smooth material discharge.

[0015] When the feeding frame needs to be replaced or repaired, the disassembly and assembly mechanism is used. Loosen the fixing post and push the side plate to separate it from the rectangular plate. At this time, the insert plate can be removed from the slot at the bottom of the placement box, and then the feeding frame can be removed from the placement box. During installation, insert the insert plate of the rectangular plate on the feeding frame into the slot at the bottom of the placement box, and then push the side plate so that its inner wall is in close contact with the two sides of the rectangular plate. Finally, tighten the fixing post. The feeding frame is fixedly installed through the threaded connection between the fixing post and the side plate and the contact between the side plate and the rectangular plate. The anti-slip rubber pads set at the contact points between the side plate and the rectangular plate increase the friction between the two and improve the stability of the installation.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this invention, the striking mechanism uses a motor to drive the rotating rod, protrusions, and other components to periodically strike the material feeding frame. This reduces the likelihood of material adhering to the inner wall of the feeding frame during the feeding process, ensuring that the material is smoothly and evenly spread on the road surface, thus improving construction efficiency and quality. The design of the disassembly and assembly mechanism makes the installation and disassembly of the feeding frame simple and quick. The feeding frame can be disassembled and assembled by pushing the side plates and tightening or loosening the fixing posts, facilitating replacement, repair, or cleaning of the feeding frame and reducing maintenance and time costs.
