Description

Technical Field

[0001] This utility model relates to the field of crushing mechanism technology, specifically a crushing mechanism for construction stone used in highways. Background Technology

[0002] The block stones used in highway engineering are usually derived from the quarrying and processing of natural rocks, and occasionally natural pebbles are also used. During the selection process, priority should be given to hard stones that are uniform in properties, not easily weathered, and free of cracks. Furthermore, various industries have specific requirements for the quality of sand and gravel, such as flaky and needle-like particles, mud content, clay lump content, stone powder content, and strength.

[0003] As disclosed in the authorization announcement number CN113617667B, a stone processing equipment for construction includes a stone crushing device. The stone crushing device includes a feeding shell and a crushing mechanism. The crushing mechanism is provided inside the feeding shell. The bottom of the feeding shell has a conical discharge hopper. The lower part of the discharge hopper is connected to a discharge port. A stone sorting device is provided below the stone crushing device. The stone sorting device includes a base, a sorting plate, and a vibrating frame. The sorting plate is installed above the base through the vibrating frame and is inclined.

[0004] Although it achieves regular vibration of the sorting plate driven by the vibrator, it efficiently classifies and separates particles according to size by multiple baffles on the left and right, making it convenient for stones to be used in construction according to different particle sizes. Compared with the multi-layer screen separation of the existing technology, it has higher strength. The screens in the existing technology are difficult to withstand the long-term impact of the stones, and the multi-layer screens are not easy to clean. This device is more durable and the sorting plate is easy to clean.

[0005] However, this does not solve the problem that existing crushing mechanisms of this type are generally not conducive to the convenient crushing of road construction stones, are not convenient for the thorough crushing of larger road construction stones, thus affecting the crushing effect of road construction stones, and are not convenient for the crushing mechanism to carry out the crushed road construction stones in a continuous flow, thus affecting the efficiency of crushing and conveying road construction stones.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A road construction stone crushing mechanism includes a conveyor frame and a support frame. Support frames are symmetrically mounted on the top of the conveyor frame, and a servo motor is mounted on the top of one set of support frames. A crushing chamber is installed between the two sides of the support frame, and a feed hopper is installed on the top of the crushing chamber. A feeding conveyor is provided outside the conveyor frame. A pulley assembly is provided at the output end of the servo motor. A rotating shaft is movably mounted inside the crushing chamber, extending to the outside of the crushing chamber, and the pulley assembly extends to the surface of the rotating shaft. Multiple sets of crushing blades at equal intervals are fitted onto the surface of the rotating shaft on one side of the crushing chamber. Adjusting frames are symmetrically mounted on the outer wall of the crushing chamber. Drive arms are slidably mounted on the outer wall of the crushing chamber on one side of the adjusting frame, extending into the interior of the crushing chamber. Springs are fitted onto the surface of each drive arm, with one end of the spring connected to the drive arm and the other end of the drive arm connected to the adjusting frame. Impact plates are provided inside the crushing chamber on one side of the drive arm.

[0009] Optionally, a drive shaft is installed on the outer wall of the impact plate near the drive arm, and the drive arm is connected to the impact plate through the drive shaft. A support seat is installed inside the crushing chamber on one side of the impact plate.

[0010] Optionally, a drive shaft is installed on the outer wall of each support base, and the support base is movably connected to the impact plate via the drive shaft. A hard filter screen is installed at the bottom of the crushing chamber.

[0011] Optionally, a stepper motor is installed on the outer wall of the conveyor frame, and a conveyor shaft is installed at the output end of the stepper motor. The conveyor shaft extends to the outside of the conveyor frame and is movably connected to the conveyor frame.

[0012] Optionally, the surface of the conveyor shaft is symmetrically fitted with drive sprockets, and the surface of each drive sprocket is fitted with a chain.

[0013] Optionally, a limit frame is installed at the top of the conveyor frame on one side of the chain, and the chain is slidably connected to the limit frame.

[0014] Optionally, a support shaft is movably mounted on the top of the conveyor frame on the side away from the conveyor shaft, and the support shaft extends to the outside of the conveyor frame.

[0015] Optionally, driven sprockets are symmetrically fitted on the surface of the support shaft, and the chains extend to the surface of the driven sprockets on the adjacent side.

[0016] Optionally, a support block is installed at the bottom of the conveyor frame, a lifting cylinder is installed at the top of the support block, and a drive plate is installed at the output end of the lifting cylinder.

[0017] Optionally, multiple sets of storage boxes with equal spacing are provided on the outside of the conveyor frame on one side of the chain, and the storage boxes are slidably connected to the chain.

[0019] A stepper motor moves the storage bin below the hard filter screen. A lifting cylinder moves the storage bin to a suitable position, placing the road construction stone on the surface of the feeding conveyor. The feeding conveyor is then turned on to facilitate the transport of the road construction stone through the feed hopper into the crushing chamber. A servo motor drives the pulley assembly to rotate, which in turn drives the rotating shaft. The crushing chamber provides movable support for the rotating shaft, which in turn drives multiple sets of crushing blades to rotate, facilitating the crushing of the road construction stone by these blades. Supported by an adjusting frame, a spring provides elastic support for the drive arm, while the crushing chamber provides sliding support for the drive arm. The drive arm, via the drive shaft, drives the impact plate to rotate elastically around the transmission shaft. This allows the impact plate to elastically rebound the road construction stone splashed by the multiple sets of crushing blades back into the working range of the blades. This achieves convenient crushing of the road construction stone by the crushing mechanism, facilitating thorough crushing of larger road construction stones and improving the crushing effect.

[0020] The lifting cylinder drives the drive plate to move, which in turn moves the storage box to facilitate its movement onto the chain surface. The stepper motor drives the conveyor shaft to rotate, which in turn drives the drive sprocket to rotate. The drive sprocket then moves the chain, which in turn moves the storage box and the crushed road construction stone to the next process. This achieves convenient, continuous conveying of the crushed road construction stone by the crushing mechanism, improving the efficiency of crushing and conveying road construction stone, reducing manual labor intensity, and enhancing the convenience of crushing and conveying road construction stone.
