Description

Technical Field

[0001] The invention relates to the technical field of concrete crushing, in particular to a concrete crushing device for municipal construction. Background Art

[0002] Municipal engineering refers to projects related to the construction of urban public infrastructure, which is an important support for urban development. It covers a wide range of areas, including urban roads, bridges, drainage, water supply, gas, heat, landscaping, environmental sanitation, public transportation and many other fields. These projects are closely related to the lives of citizens. Roads and bridges build urban transportation networks and ensure convenient travel. They are public, systematic and long-term, and are an important carrier for the government to provide public services to the public.

[0003] In the prior art, concrete crushing devices are required for municipal construction. Traditional crushing devices usually use hydraulic devices to drive the crushing mechanism to rise and fall, thereby impacting the concrete surface for crushing. However, when the hydraulic device descends, it takes a certain amount of time for the hydraulic pressure to decrease, resulting in a low speed of the crushing mechanism when descending. Multiple impacts are required to achieve the ideal effect, which affects the working efficiency of the device. In addition, the hydraulic device drives the crushing mechanism to rise and fall back and forth, which increases the operating burden of the hydraulic device. Therefore, in order to solve the above problems, the present invention proposes a concrete crushing device for municipal construction. Summary of the Invention

[0004] The present invention provides a concrete crushing device for municipal construction, which has the advantage of a fast falling hammer, increases the impact force of the crushing teeth on the concrete, improves the crushing effect of the device, and enhances the working efficiency of the crushing device. The hydraulic rod only needs to lift the crushing mechanism, which reduces the operating burden of the hydraulic device and increases the service life of the hydraulic device, thereby solving the problems in the above-mentioned background technology.

[0005] The present invention provides the following technical solution: a concrete crushing device for municipal construction, comprising a tractor, wherein a connecting plate is fixedly installed at the rear of the tractor, a connecting seat is fixedly installed at the rear of the connecting plate, a sleeve is evenly fixedly sleeved on the upper part of the connecting seat, the sleeves are four in number and are in groups of two, a connecting block is evenly fixedly installed at the edge of the upper part of the sleeve, the connecting block is movably connected to a limit claw through a shaft, the side surface of the sleeve is evenly movably connected to an electric push rod through the shaft, the electric push rod is five in number, the telescopic end of the electric push rod is movably connected to the limit claw through the shaft, an impact hammer is movably sleeved in the inner cavity of the sleeve, the bottom of the impact hammer is fixedly connected to crushing teeth, the side surface of the impact hammer is evenly provided with racks, the racks are five in number and are respectively engaged with the limit claws, the engagement of the limit claws and the racks is adjusted by the electric push rod to achieve the fixing and release of the impact hammer, thereby improving the impact force of the impact hammer on concrete, improving the crushing effect of the device, and enhancing the working efficiency of the crushing device.

[0006] Preferably, a hydraulic rod is fixedly installed on the upper part of the connecting seat and between the two sleeves, a top plate is fixedly installed on the telescopic end of the hydraulic rod, and a chain 1 is fixedly installed on the bottom of the top plate. There are two chains 1 and they are respectively fixedly connected to the top of the impact hammer. The top plate is driven to rise by the hydraulic rod, and the top plate pulls the impact hammer up through the chain 1. After the impact hammer is fixed, the telescopic end of the hydraulic rod is retracted, which reduces the operating burden of the hydraulic device and improves the service life of the hydraulic device.

[0007] Preferably, a water tank is fixedly installed on the upper part of the connecting plate, a sprinkler is fixedly installed on the bottom of the connecting seat and in front of the crushing teeth, nozzles are evenly fixedly installed on the bottom of the sprinkler, a current valve is fixedly installed on the rear of the sprinkler, a connecting line is fixedly connected between the nozzle and the current valve, and conductive electrode needles are fixedly installed symmetrically in the inner cavity of the nozzle. When the sprinkler is turned on, spraying is carried out through the nozzle. At the same time, the current valve transmits current to the conductive electrode needle through the connecting line, so that the liquid sprayed by the nozzle is charged. When the water is sprayed, it is broken into charged droplets due to surface tension, which absorbs dust generated when the concrete is crushed.

[0008] Preferably, a dust collector is fixedly installed at the bottom of the connecting seat and behind the crushing teeth, a dust suction port is opened at the bottom of the dust collector, a dust collection box is fixedly installed on the upper part of the connecting seat and behind the sleeve, a dust collection pipe is fixedly connected between the dust cleaner and the dust collection box, and a cover is movably connected to the upper part of the dust collection box through an axis. When the dust cleaner is turned on, the dust suction port absorbs dust and water vapor generated by the spray, and these impurities are collected into the dust collection box through the dust collection pipe, and the cover can be opened regularly to clean the inside of the dust collection box.

[0009] Preferably, a universal wheel is fixedly installed at the bottom of the connecting seat and located behind the vacuum cleaner. There are two universal wheels and they are symmetrically distributed on the left and right. Chain 2 is fixedly installed evenly around the bottom of the connecting seat and located around the sprinkler and the vacuum cleaner. Chain 2 is used to block the gravel generated when the concrete is crushed, preventing small gravel from splashing everywhere, thereby ensuring the safety of the environment around the device.

[0010] The present invention has the following beneficial effects: 1. The electric push rod drives the limit claw to rotate, so that the limit claw and the rack are connected, thereby fixing the raised impact hammer. After the telescopic end of the hydraulic rod is retracted, the electric push rod is used to disconnect the connection between the limit claw and the rack, so that the impact hammer slides and falls along the inner cavity of the sleeve under the action of gravity, thereby crushing the ground. Compared with the traditional method of using a hydraulic device to drive the crushing mechanism to descend, it is beneficial to increase the falling speed of the impact hammer and increase the impact force of the crushing teeth on the concrete, thereby improving the crushing effect of the device and enhancing the working efficiency of the crushing device. The hydraulic rod only needs to lift the crushing mechanism, which reduces the operating burden of the hydraulic device and increases the service life of the hydraulic device.

[0011] 2. The water in the water tank is sprayed from the nozzle through the sprinkler, and the current valve is used to transmit the current through the connecting line to the conductive electrode needle, so that the liquid sprayed by the nozzle is charged. When the water is sprayed, it is broken into charged droplets due to surface tension, which absorbs the dust generated when the concrete is crushed. Compared with traditional spraying that relies on inertial collision and gravity sedimentation, there is Coulomb attraction between the charged droplets and the dust particles. Even in the case of ultra-fine dust, efficient adsorption can be achieved through the action of charge, effectively enhancing the dust removal effect of the spray. After the charged droplets collide with the dust particles, the charge is neutralized to make the tiny particles aggregate into large particles, accelerating gravity sedimentation, thereby improving the dust removal efficiency and reducing water consumption under the same dust removal effect.

A crushing tooth 9 is fixedly connected to the bottom of the impact hammer 8. Racks 10 are evenly opened on the side of the impact hammer 8. There are five racks 10 and they are respectively engaged with the limit claw 6. A hydraulic rod 11 is fixedly installed on the upper part of the connecting seat 3 and located between the two sleeves 4. A top plate 12 is fixedly installed on the telescopic end of the hydraulic rod 11. A chain 13 is fixedly installed at the bottom of the top plate 12. There are two chains 13 and they are respectively fixedly connected to the top of the impact hammer 8. The tractor 1 is driven by a tractor. The driving device moves to the working site, and the hydraulic rod 11 is turned on to drive the top plate 12 to rise. The top plate 12 pulls the impact hammer 8 up through the chain 13. When the impact hammer 8 rises to the appropriate position, the electric push rod 7 is turned on. The telescopic end of the electric push rod 7 drives the limit claw 6 to rotate, so that the limit claw 6 and the rack 10 are connected, thereby fixing the impact hammer 8. After fixing, the hydraulic rod 11 is adjusted to retract its telescopic end, and then the limit claw 6 is driven by the electric push rod 7 to rotate, and the connection between the limit claw 6 and the rack 10 is disconnected. At this time, the impact hammer 8 slides and falls along the inner cavity of the sleeve 4 under the action of gravity, so that the crushing teeth 9 at the bottom of the impact hammer 8 crush the ground. Compared with the traditional method of using a hydraulic device to drive the crushing mechanism to descend, the impact hammer 8 is directly released by disconnecting the connection, which is conducive to increasing the falling speed of the impact hammer 8 and increasing the impact force of the crushing teeth 9 on the concrete, thereby improving the crushing effect of the device, and enhancing the working efficiency of the crushing device. The hydraulic rod 11 only needs to lift the crushing mechanism, which reduces the operating burden of the hydraulic device and prolongs the service life of the hydraulic device. A water tank 14 is fixedly installed on the upper part of the connecting plate 2, a sprinkler 15 is fixedly installed at the bottom of the connecting seat 3 and in front of the crushing tooth 9, a nozzle 16 is evenly fixedly installed at the bottom of the sprinkler 15, a current valve 17 is fixedly installed at the rear of the sprinkler 15, a connecting line 18 is fixedly connected between the nozzle 16 and the current valve 17, and a conductive electrode needle 19 is fixedly installed symmetrically in the inner cavity of the nozzle 16, a vacuum cleaner 20 is fixedly installed at the bottom of the connecting seat 3 and behind the crushing tooth 9, and a vacuum port 21 is opened at the bottom of the vacuum cleaner 20. 3 and is fixedly installed at the upper part of the sleeve 4. A dust collecting box 22 is fixedly installed between the dust collector 20 and the dust collecting box 22. A dust collecting pipe 23 is fixedly connected to the dust collecting box 22. A cover plate 24 is movably connected to the upper part of the dust collecting box 22 through an axis. A universal wheel 25 is fixedly installed at the bottom of the connecting seat 3 and is located behind the dust collector 20. There are two universal wheels 25 and they are symmetrically distributed on the left and right. A chain 26 is evenly fixedly installed around the bottom of the connecting seat 3 and the sprayer 15 and the dust collector 20. When the dust is crushed, the sprayer 15 is opened at the same time to spray the water in the water tank 14 through the sprayer. The nozzle 16 sprays, and the current valve 17 is opened so that the current is transmitted to the conductive electrode needle 19 through the connecting line 18, so that the liquid sprayed by the nozzle 16 is charged. When the water is sprayed, it is broken into charged droplets due to surface tension, which absorbs the dust generated when the concrete is crushed. Compared with the traditional spraying that relies on inertial collision and gravity sedimentation, there is a Coulomb attraction between the charged droplets and the dust particles. Even in the case of ultra-fine dust, it can achieve efficient adsorption through the action of charge, effectively enhancing the spray dust removal effect. After the charged droplets collide with the dust particles, Charge neutralization causes tiny particles to aggregate into larger particles, accelerating gravity sedimentation, thereby improving dust removal efficiency and reducing water consumption under the same dust removal effect. The vacuum cleaner 20 is then turned on to allow the suction port 21 to absorb dust and water vapor generated by the spray, and these impurities are collected into the dust box 22 through the dust collecting pipe 23. The cover 24 can be opened regularly to clean the inside of the dust box 22, and the chain 26 is used to block the gravel generated when the concrete is crushed to prevent small gravel from splashing everywhere, thereby ensuring the safety of the environment around the device.

[0016] Working principle: The device is moved to the working site by the tractor 1, and the hydraulic rod 11 is turned on to drive the top plate 12 to rise. The top plate 12 pulls the impact hammer 8 to rise through the chain 13. When the impact hammer 8 rises to the appropriate position, the electric push rod 7 is turned on. The telescopic end of the electric push rod 7 drives the limit claw 6 to rotate, so that the limit claw 6 and the rack 10 are connected, thereby fixing the impact hammer 8. After fixing, adjust the hydraulic rod 11 to retract its telescopic end, and then drive the limit claw 6 to rotate through the electric push rod 7 to disconnect the connection between the limit claw 6 and the rack 10. At this time, the impact hammer 8 slides down along the inner cavity of the sleeve 4 under the action of gravity, so that the crushing teeth 9 at the bottom of the impact hammer 8 are against the ground. The concrete surface is crushed, and the sprinkler 15 is turned on at the same time to spray the water in the water tank 14 through the nozzle 16. The current valve 17 is turned on to transmit the current to the conductive electrode needle 19 through the connecting line 18, so that the liquid sprayed by the nozzle 16 is negatively charged. When the water is sprayed, it is broken into negatively charged droplets due to surface tension, which absorbs the dust generated when the concrete is crushed. Then the vacuum cleaner 20 is turned on to make the dust suction port 21 absorb the dust and the water vapor generated by the spraying, and these impurities are collected into the dust box 22 through the dust collecting pipe 23. The cover 24 can be opened regularly to clean the inside of the dust box 22, and the chain 26 is used to block the gravel generated when the concrete is crushed.
