Description

Technical Field

[0001] This utility model relates to a gravel cleaning device, and more particularly to a road surface maintenance device for highway construction, belonging to the field of highway maintenance technology. Background Technology

[0002] Highway surface maintenance includes road sweeping, gravel removal, and crack filling. During this process, gravel and debris accumulate on the road surface, posing safety hazards if not cleaned up promptly. During construction, safety warning signs must first be placed near the construction site. Then, workers clean up the gravel. Since the garbage collection vehicles are mostly large trucks with high cargo beds, workers need to lift the garbage to a certain height to accurately place it into the truck bed. During this process, garbage may not fit or may scatter. Furthermore, since the trucks stop at fixed points, workers must also move the garbage closer to the truck before it can be disposed of. This method is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a road surface maintenance device for highway construction, which facilitates the unified disposal of garbage by workers, improves work efficiency, and reduces labor intensity.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] A road surface maintenance device for highway construction includes a U-shaped frame, a displacement frame, and a hopper. The displacement frame is slidably connected to both sides of the U-shaped frame. A vertical plate is provided at the front end of the displacement frame, and a lead screw is provided on the left vertical plate. A support column is provided on the right vertical plate. A displacement rod is sleeved on the lead screw and the support column. One end of the displacement rod is connected to the lead screw, and the other end is slidably connected to the support column. A first motor is provided at the top of the lead screw. A hopper is rotatably connected to the displacement rod, and a guide hopper is provided on the U-shaped frame.

[0006] A connecting rod is provided between the inner walls of the U-shaped frame. A guide wheel is provided at the top of the connecting rod. Two clamping plates are provided on both sides of the bottom of the rear end of the connecting rod, and tightening bolts are provided on the clamping plates.

[0007] The right end of the U-shaped frame has two extension plates on both sides, and the displacement frame passes through the extension plates and is slidably connected to them.

[0008] The upper and lower ends of the vertical plate are respectively provided with end plates. The support column is fixedly connected to the two end plates on one of the vertical plates, and the lead screw is rotatably connected to the two end plates on the other vertical plate.

[0009] An end block is provided in the middle of the right end face of the displacement rod, and a U-shaped end frame is rotatably connected to the outside of the end block. A worm wheel is provided on one side of the U-shaped end frame, and a worm is connected above the worm wheel. The end of the worm wheel is connected to the output end of the second motor, which is mounted on the displacement rod.

[0010] The right end of the U-shaped end frame is provided with a first end plate, and the back of the hopper is provided with a second end plate. The first end plate and the second end plate are fixedly connected together by bolts, and the second end plate is located in the middle of the back of the hopper.

[0011] The bottom of the hopper is equipped with rollers.

[0012] The positive and beneficial effects of this utility model are:

[0013] 1. This utility model, by setting displacement rods on the support column and lead screw, can lift the hopper under the action of the first motor, and tilt the hopper under the action of the second motor, worm gear and worm, so that the garbage in the hopper can be tilted into the guide hopper, which makes it easier for workers to accurately put the crushed stone garbage. At the same time, it reduces the construction intensity and improves the work efficiency.

[0014] 2. The hopper and end frame of this utility model are fixedly connected together by bolts, which makes it easy for workers to disassemble the hopper for separate use. By setting rollers at the bottom of the hopper, it is easy for workers to collect and transport garbage on the ground, saving time and effort and making the operation simple.

[0015] 3. This utility model uses guide wheels on a U-shaped frame to facilitate the movement of the guide hopper, avoiding the situation where the guide hopper is difficult to move due to a large amount of garbage and gravel inside and its overall weight. When the hopper is raised to a certain height, the displacement frame moves the hopper backward and tilts the garbage inside, allowing it to enter the guide hopper. The operator in the crane only needs to tilt the garbage in the guide hopper into the crane hopper, avoiding the situation of garbage scattering during the feeding process, thus achieving precise feeding.

[0034] Working principle:

[0035] Before cleaning up the garbage, the clamping plate at the bottom of the U-shaped frame is clamped onto the side plate of the vehicle and secured with the tightening bolts. When cleaning up the garbage, the bolts between the first end plate and the second end plate are loosened to separate the hopper from the end frame, allowing workers to push the hopper to collect the garbage. When the garbage is full, the first end plate and the second end plate are connected together, and the second motor is started to move the hopper upwards. When the height of the hopper exceeds the height of the displacement frame, the displacement frame is pulled back, and the first motor is started to tilt the hopper until the garbage in the hopper is dumped into the guide hopper. Workers inside the crane then drag the guide hopper from the displacement frame into the crane's hopper.

[0036] This invention features displacement rods on the support pillars and lead screws. A first motor lifts the hopper, while a second motor quickly tilts the waste inside, enabling precise waste disposal. Rollers are installed at the bottom of the hopper. The hopper and end frame are detachable, facilitating waste transportation and collection on the ground. The invention is convenient, easy to use, and simple to operate, improving work efficiency and reducing labor intensity.
