Description

Technical Field

[0001] This invention belongs to the field of municipal construction, specifically a protective cutting machine for municipal construction. Background Technology

[0002] In municipal road maintenance, reconstruction, and pipeline laying, road cutting is a fundamental and frequent process. It is mainly used to cut cement concrete, asphalt, and other road materials to create expansion joints, settlement joints, or trenches, providing the necessary conditions for subsequent grouting, demolition, and repair work. With the acceleration of urbanization, municipal road construction demands increasingly higher efficiency, construction quality, safety, and environmental protection. As a core piece of equipment, the performance of road cutting machines directly affects construction progress and on-site management. Currently, most road cutting machines for municipal construction on the market adopt a traditional structural design, mainly consisting of a power motor, cutting saw blade, machine frame, walking mechanism, and spray cooling system. The motor drives the saw blade to rotate at high speed, and road cutting is completed with manual or mechanical traction. However, the following shortcomings still exist: Urban roads are mostly divided into two types: cement roads and asphalt roads. When cutting cement roads, a lot of dust and gravel are easily generated, which pollutes the environment and can easily injure nearby workers. When cutting asphalt roads, the asphalt melts and easily adheres to the cutting wheel, which increases the cutting resistance and reduces the cutting efficiency. Summary of the Invention

A top sliding frame 4106 is fixedly mounted on the top of the cutting box 401. 5 is slidably connected to the top sliding frame 4106. The top sliding frame 4106 has a first screw 4107 rotatably mounted inside. The first screw 4107 is threadedly connected to the U-shaped frame 4105. The top end of the first screw 4107 is fixedly connected to the output shaft of the first rotating motor 4108.

The first rotating motor 4108 drives the first screw 4107 to rotate, causing the toothed plate 4103 to move downward, which in turn drives the rotating cylinder 40961 to rotate. This facilitates the adjustment of the orientation of the rotating cylinder 40961 and controls the output of the atomizing hole 40965 and the water spray nozzle 40966, making it convenient to use.

[0023] The range adjustment assembly 411 includes an arc-shaped baffle 4116 disposed on the side of the rotating cylinder 40961 near the inner cavity of the cutting box 401. A groove 4117 is formed on the arc-shaped baffle 4116 along the length of the rotating cylinder 40961. A fixed slider 4118 is fixedly installed on the inner wall of the cutting box 401, and the fixed slider 4118 is slidably connected to the groove 4117. A connecting plate 4119 is installed on the front side of the arc-shaped baffle 4116, and an inner plate 4 is provided on the inner side of the cutting box 401. 114, an inner plate 4114 is disposed between two connecting plates 4119. First connecting rods 41110 are symmetrically hinged to both sides of the inner plate 4114. The bottom ends of the two first connecting rods 41110 are respectively hinged to the two connecting plates 4119. A connecting slide plate 41112 is fixedly installed on the top of the inner plate 4114. A top through groove 41111 is opened on the top of the cutting box 401. The connecting slide plate 41112 is slidably installed inside the top through groove 41111. A return spring 4115 is symmetrically installed at the top of the 114. The top of the return spring 4115 is fixedly connected to the inner top wall of the cutting box 401. A clamping and fixing assembly 412 is provided on both sides of the connecting slide plate 41112. A top plate 4111 is fixedly installed at the top of the bottom plate 4113. The top plate 4111 is located above the cutting box 401. A bottom plate 4113 is provided on the side of the cutting box 401 near the moving vehicle 1. The bottom plate 4113 is connected to the top wall of the protective box 402. A connecting frame 4112 is symmetrically installed between the top plate 4111 and the bottom plate 4113. The bottom plate 4113 contacts the top wall of the protective box 402. When adjusting the cutting depth, the cutting box 401 moves longitudinally along the protective box 402, thereby driving the inner plate 4114 to move synchronously. Then, the first connecting rod 41110 pulls the two arc-shaped baffles 4116 to move, adjusting the water outlet range so that the water outlet range can be adapted to the cutting depth of the cutting wheel 406.

[0024] The clamping and fixing assembly 412 includes side grooves 4121 symmetrically opened on both sides of the connecting frame 4112. A clamping plate 4122 is disposed inside the side groove 4121, and the clamping plate 4122 contacts the side wall of the connecting slide plate 41112. A pressure plate 4123 is disposed on the side of the clamping plate 4122 away from the connecting slide plate 41112. A clamping spring 4124 is installed between the pressure plate 4123 and the clamping plate 4122. A push rod 4125 is fixedly installed on the side of the pressure plate 4123 away from the connecting slide plate 41112. One end of the push rod 4125 extends through to the outside of the cutting box 401, and a second connecting rod 4126 is hinged to the end of the push rod 4125. The top of the second connecting rod 4126 is hinged to the U-shaped frame 4105. When cutting cement pavement, the U-shaped frame 4105 moves downward, so that the atomizing hole 40965 faces the inner cavity of the cutting box 401. The second connecting rod 4126 pushes the pressure plate 4123 toward the clamping plate 4122, so that the compression spring 4124 is compressed. Then, under the elastic force of the compression spring 4124, the two clamping plates 4122 clamp the connecting slide plate 41112, ensuring the fixing effect of the arc baffle 4116 and the stability of the water outlet range when the vibration of cutting cement pavement is too large. Since the asphalt pavement is softer, the cutting vibration is much less than that of cement pavement cutting.

[0025] Working principle: In its original state, the water nozzle 40966 on one side of the rotating cylinder 40961 is located near the inner cavity of the cutting box 401, which is suitable for cutting asphalt pavement. During use, the equipment is moved to the pavement to be cut, and the output pipe of the water tank 2 is connected to the top pipe 4095 through a hose. A water pump is installed on the output pipe of the water tank 2. Then, the drive motor 408 is turned on to drive the cutting wheel 406 to rotate. Then, the second rotating motor 7 is turned on to drive the second screw 6 to rotate. Since the second screw 6 is threadedly connected to the longitudinal sliding plate 5, it drives the cutting box 401 to move downward, thereby adjusting the cutting depth. During this process, the protective box 402 is always fitted outside the cutting box 401 to block cutting dust and prevent dust from spreading. At the same time, it prevents stones and other debris from flying and causing injury to surrounding workers or passers-by during the cutting process, thus playing a protective role. When the cutting box 401 moves downward relative to the protective box 402, the bottom plate 4113 contacts the top wall of the protective box 402, causing the top plate 4111 to rise under pressure, which in turn causes the internal plate 4114 inside the cutting box 401 to rise. The internal plate 4114 is connected to the two side connecting plates 4119 by two first connecting rods 41110. When the internal plate 4114 moves upward, it causes the two connecting plates 4119 to move closer to each other, which in turn causes the arc-shaped baffles 4116 to move closer to each other, thereby opening some of the water spray nozzles 40966 or some of the atomizing holes 40965, so that the water outlet range is adapted to the cutting depth of the cutting wheel 406. When cutting asphalt pavement, the water pump is turned on, driving water from the water tank 2 into the rotating drum 40961, and then spraying it out from the spray nozzle 40966 toward the side surface of the cutting wheel 406. The spray nozzle 40966 is designed in the shape of an isosceles trapezoid, so that the water flow is accelerated when it enters the spray nozzle 40966, increasing the force of the water flow impacting the surface of the cutting wheel 406. On the one hand, it can cool the cutting wheel 406, and on the other hand, it can wash the surface of the cutting wheel 406, preventing asphalt from sticking to the surface of the cutting wheel 406 when cutting asphalt, which would increase the subsequent cutting resistance. When cutting the cement road surface, the first rotating motor 4108 is turned on, driving the first screw 4107 to rotate. Since the U-shaped frame 4105 is threadedly connected to the first screw 4107, the U-shaped frame 4105 is driven to move downward, which in turn drives the toothed plate 4103 to move downward. The toothed plate 4103 is meshed with the gear 40964, which drives the rotating cylinder 40961 to rotate 180 degrees, so that the atomizing hole 40965 faces the inside of the cutting box 401. Then the water pump is turned on, and water is atomized from the atomizing hole 40965 and sprayed onto the inside of the cutting box 401 and the surface of the cutting wheel 406. On the one hand, the cutting wheel 406 is cooled down, and on the other hand, the atomized water droplets combine with the dust generated by cutting the cement road surface in the air and settle down, which plays a role in dust removal. Simultaneously, as the U-shaped frame 4105 moves downward, the second connecting rod 4126 pushes the pressure plate 4123 toward the clamping plate 4122, compressing the compression spring 4124. Then, under the elastic force of the compression spring 4124, the clamping plates 4122 on both sides clamp the connecting slide plate 41112, improving the fixing effect of the arc baffle 4116 and avoiding the decrease in spraying effect due to excessive vibration when cutting cement pavement, where the vibration of cutting cement pavement is much greater than that of cutting asphalt pavement. Furthermore, when water is sprayed onto the surface of the cutting wheel 406, the continuous rotation of the cutting wheel 406 accelerates the sprayed water under the action of centrifugal force and carries it to other positions inside the cutting box 401, expanding the water mist diffusion range and improving the dust removal effect.
