Description

Technical Field

[0002] In the existing technology, there are many devices for crushing concrete pavements. The resonance crushing technology is mainly used in the renovation projects of concrete roads, municipal concrete roads, concrete tanks, and concrete highways. It can also be used for the demolition of cement floors such as factories, docks, and parking lots. On some roads, it is very necessary to debond the pavement from the roadbed before using the concrete pavement resonance crushing equipment.

[0003] For example, a Chinese patent (publication number: CN108316118A) discloses a full-range resonance stone crushing device for a concrete pavement, comprising a bracket, a traveling system, a power supply system and a stone crushing system, wherein the bracket is arranged on the traveling system, the stone crushing system comprises a vibrating beam, an eccentric block, a transmission device and a hammer head, the power output shaft of the transmission device is connected to the eccentric block by transmission, the tail end of the vibrating beam is connected to the eccentric block, the hammer head is installed at the front end of the vibrating beam through a hammer head bracket, the vibrating beam is hinged on the bracket, a positioning block is arranged on the top of the vibrating beam, the positioning block limits the upward path of the vibrating beam, the hinge point of the vibrating beam is staggered with the positioning block, when the vibrating beam is driven by the eccentric block to swing, due to the action of the hinge point and the positioning block, the vibrating beam is excited in an S shape; the hammer head works on one side of the traveling system, the invention has a reasonable structure, and can crush the concrete pavement throughout the whole process without omission, and will not affect the foundation.

[0004] The above-mentioned full-process resonance stone crushing equipment for concrete pavement still has certain shortcomings. The improved full-process resonance stone crushing equipment for concrete pavement uses the harmonic principle to oscillate up and down. When the eccentric block moves, it generates a swinging force on the beam, and the hammer head on the beam will instantly contact the ground and then immediately leave the ground. These actions are all achieved by the cooperation of the eccentric block, the hinge point and the positioning block. However, a large amount of dust will be generated in the process of crushing the stones, and the resonance stone crushing equipment cannot effectively suppress the dust, resulting in the spread of dust and affecting the surrounding environment. Therefore, this application proposes a new type of resonance stone crushing equipment for concrete pavement to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] See also Figure 1 A novel resonance stone crushing device for concrete pavement in this embodiment includes a vehicle body 1. A stone crushing assembly 2 is provided inside the vehicle body 1 for striking the concrete pavement to produce stone crushing. A dust removal mechanism 3 for removing dust from the stone crushing is provided on the right side of the vehicle body 1 for spraying water on the concrete pavement to prevent dust from flying. A protective mechanism 4 for protecting the dust removal mechanism 3 is provided on the dust removal mechanism 3. The vehicle body 1 is protected by the protective mechanism 4 to prevent damage to the vehicle body 1 after a collision.

[0033] It should be noted that the stone crushing assembly 2 is a device in the prior art. The stone crushing assembly 2 includes a bracket, a walking system, a power supply system and a stone crushing system. The bracket is arranged on the walking system. The stone crushing system includes a vibrating beam, an eccentric block, a transmission device and a hammer head. The power output shaft of the transmission device is connected to the eccentric block by transmission. The tail end of the vibrating beam is connected to the eccentric block. The hammer head is installed at the front end of the vibrating beam through the hammer head bracket. The vibrating beam is hinged to the bracket. A positioning block is provided on the top of the vibrating beam. The positioning block limits the upward path of the vibrating beam. The hinge point of the vibrating beam and the positioning block are staggered. When the vibrating beam is driven by the eccentric block to swing, due to the action of the hinge point and the positioning block, the vibrating beam is S-shaped and excited. The hammer head works on one side of the walking system. According to the harmonic principle, it will oscillate up and down. When the eccentric block moves, it will generate a swinging force on the beam. The hammer head on the beam will instantly contact the ground and then leave the ground immediately. These actions are achieved by the cooperation of the eccentric block, the hinge point and the positioning block. Therefore, the impact force borne by the concrete floor will not increase. After the force is applied, cracks will appear at the stressed part and the concrete floor will be broken instantly. At the same time, the hammer head works on one side of the walking system, which can crush the road surface throughout the entire process to avoid omissions on both sides of the road surface that cannot be reached and need to be supplemented by manual labor and excavators. In addition, since the crushing of the concrete road surface will generate dust, the dust removal mechanism 3 can be set to irrigate the impacted part to prevent dust from being generated without affecting the surrounding environment.

[0037] In addition, a water inlet pipe is fixed to the back of the water tank 301, and a control valve is fixed to the back of the water inlet pipe to facilitate the control of water inlet into the water tank 301. The lower surfaces of the two second water pipes 304 on the opposite sides are respectively fixed to the front and rear sides of the spray box 305. The spray box 305 and the second water pipe 304 are both U-shaped. The water pump 303 draws the water in the water tank 301 through the first water pipe 302 and sends it to the second water pipe 304, and the water will continue to enter the spray box 305.

[0044] In the protective mechanism 4 of this embodiment, when the baffle 406 collides with an obstacle, the baffle 406 drives the fixed rod 405 to move and squeezes the first spring 404. The baffle 406 also drives the push block 411 to move together. The push block 411 pushes the moving block 410 to slide on the outer surface of the sliding rod 408 and squeezes the second spring 409. The baffle 406 is buffered by the first spring 404 and the second spring 409 to prevent the collision with the obstacle and cause damage to the vehicle body 1.

[0045] The working principle of the above embodiment is:
