Description

Technical Field

[0001] The utility model relates to the field of road construction equipment, in particular to a high-pressure crushing device for municipal road repair gravel. Background Art

[0002] In municipal road repair work, high-pressure gravel crushing equipment plays a vital role. This device is specially designed to crush large pieces of waste rock into gravel of suitable size to meet the needs of municipal road repair. By using this device, not only the work efficiency is significantly improved, but also the construction quality and safety are greatly improved.

[0003] However, in the process of municipal road repair, workers first need to clean the damaged road surface. This step will produce many large stones. In order to facilitate the transportation of these waste stones, they need to be crushed on site. However, during the crushing process, the crushed stones will produce dust, which can easily escape from the inner wall of the crushing device, thereby polluting the environment.

[0004] Therefore, in view of the situation that dust can easily escape from the crushing device during the crushing process of the above-mentioned high-pressure crushing device for gravel, causing environmental pollution, a high-pressure crushing device for gravel repairing municipal roads can be designed. Through telescopic adjustment combined with rotation and spraying functions, the dust generated during the crushing can be removed while crushing the waste rock, thereby protecting the environment. Utility Model Content

[0005] In order to overcome the problem that dust can easily escape from the crushing device during the crushing process of the high-pressure stone crushing device, causing environmental pollution.

[0006] The technical solution of the utility model is: a high-pressure crushing device for gravel repairing municipal roads, comprising a tripod, a crushing box, a dust cover, a feed port, a discharge port, a drive component, a clamping component, and a spray component; the tripod is fixed to the lower end of the crushing box, the dust cover is installed at the upper end of the crushing box, the feed port is opened at the front end of the crushing box, the discharge port is opened at the rear end of the crushing box, the drive component is installed at the lower end of the dust cover, the clamping component is installed in the crushing box, and the spray component is installed at the bottom of the crushing box.

[0007] Preferably, the tripod serves as the foundation of the entire device to ensure that the device is placed firmly. The waste rock enters the crushing box through the feed port and is crushed under high pressure under the action of the drive component. The crushed gravel is discharged from the discharge port to facilitate subsequent transportation and processing. The drive component is the power source of the crushing device. The drive component crushes the waste rock under high pressure through high-speed rotating cutters. The clamping component is mainly used to fix the waste rock to be crushed to ensure that the waste rock will not move or pop out during the crushing process, thereby improving operation safety. The spray component reduces dust during the crushing process by spraying water mist, further reducing the generation and escape of dust, thereby protecting the environment.

[0008] Preferably, the driving assembly includes a hydraulic cylinder, a rotating motor, and a crushing toothed disc; the hydraulic cylinder is installed at the lower end of the dust cover, the rotating motor is installed at the hydraulic cylinder power element, and the crushing toothed disc is installed at the output shaft of the rotating motor. The hydraulic cylinder generates thrust through the pressure of the hydraulic oil to push the rotating motor and the crushing toothed disc below it to reciprocate up and down. This movement mode can ensure sufficient contact between the crushing toothed disc and the waste rock, thereby improving the crushing effect. The rotating motor is driven by electricity to provide rotational power for the crushing toothed disc. When the hydraulic cylinder pushes the rotating motor up and down, the rotating motor simultaneously drives the crushing toothed disc to rotate at high speed, thereby realizing high-pressure crushing of the waste rock. The crushing toothed disc is designed with multiple sharp crushing teeth. When the toothed disc rotates at high speed, the crushing teeth collide and shear with the waste rock, thereby crushing the waste rock into smaller particles.

[0009] Preferably, the clamping assembly includes a crossbeam and a stone frame; the stone frame is installed in the crushing box, one end of the crossbeam is fixed to the inner wall of the crushing box, and the other end is fixed to the outer wall of the stone frame. The crossbeam is the main supporting structure of the clamping assembly. The material of the crossbeam needs to have a certain strength and rigidity, such as alloy, to withstand the impact force and vibration generated during the crushing process. At the same time, it provides a stable frame for the stone frame to prevent it from shaking or moving during the crushing process. The stone frame is a container for directly loading stones to be crushed, which can accommodate a certain amount of stones. The material of the stone frame also needs to have a certain strength and wear resistance to withstand the impact and wear of the stones during the crushing process.

[0010] Preferably, the clamping assembly includes a cylinder and a splint; the cylinder is installed on the inner wall of the stone frame, and the splint is fixed to the cylinder power element. The cylinder is the power element in the clamping assembly, and there are components such as a piston and a spring inside the cylinder. When the cylinder is working, the piston will reciprocate in the cylinder to provide power. When the cylinder piston extends, it will push the splint to move toward the stone, thereby clamping the stone.

[0011] Preferably, the clamping assembly also includes a screening hole, a collecting box, and ball bearings; the screening hole is opened at the bottom of the stone frame, the collecting box is installed at the bottom of the crushing box, and the lower end of the collecting box is installed with ball bearings. The screening hole is used to screen and separate the crushed stones. The stone particles that meet the requirements will fall into the collecting box below through the screening hole, while the larger stone particles will be left in the stone frame or continue to be crushed. The ball bearings can reduce the friction between the collecting box and the bottom of the crushing box, making it easier to move the collecting box out of the discharge port.

[0012] Preferably, the spray assembly includes a water tank, a water pump, and a column; the water tank is installed at the bottom of the crushing box and is located on the left and right sides of the collecting box, the water pump is installed at the bottom of the crushing box and is located at the rear end of the water tank, and the column is installed at the bottom of the crushing box and is located at the rear end of the water tank. The function of the water tank is to store and supply spray water. When the crushing process is in progress, the water in the water tank is pumped out by the water pump. The function of the column is to support and fix the spray pipe to ensure its stability during the spraying process.

[0013] Preferably, the spray assembly also includes a spray pipe and a nozzle; the spray pipe is installed on the outer wall of the column and extends inward into the column, the nozzle is installed on the spray pipe and extends outward outside the column, and the spray pipe transports water pumped by the water pump to the nozzle for uniform spraying to remove dust.

At the same time, it provides a stable frame for the stone frame 702 to prevent it from shaking or moving during the crushing process. The stone frame 702 is a container for directly loading the stones to be crushed, which can accommodate a certain amount of stones. The material of the stone frame 702 also needs to have a certain strength and wear resistance to withstand the impact and wear of the stones during the crushing process. The cylinder 703 is the power element in the clamping assembly. There are pistons and springs inside the cylinder 703. When the cylinder 703 is working, the piston will reciprocate in the cylinder 703 to provide power. When the piston of the cylinder 703 extends When the crushed stone is discharged, the clamping plate 704 will be pushed to move toward the stone, so as to clamp the stone. The screening hole 705 is used to screen and separate the crushed stone. The stone particles that meet the requirements will fall into the collection box 706 below through the screening hole 705, while the larger stone particles will be left in the stone frame 702 or continue to be crushed.
